Description

CROSS-REFERENCE TO RELATED APPLICATION(S)

This application claims the benefit under 35 U.S.C. § 119(a) of a Korean patent application filed on Mar. 14, 2013 in the Korean Intellectual Property Office and assigned Serial number 10-2013-0027513, the entire disclosure of which is hereby incorporated by reference.

TECHNICAL FIELD

The present disclosure relates to an application management method. More particularly, the present disclosure relates to an application synchronization method of a terminal.

BACKGROUND

With the advances of technology, the mobile communication system has evolved to the level of providing various data communication services beyond early voice-oriented services. Particularly with the introduction of enhanced terminals, such as a smartphone, and an enhanced data rate network, users are capable of enjoying various data services anytime anywhere.

The enhanced terminal, such as a smartphone, supports various applications such as a mail client, a Social Network Service (SNS) client, and an Instant Messaging (IM) client. These applications are capable of connecting to a network to synchronize application data with a network entity (server). In order to achieve the synchronization of application data, the applications perform data synchronization at respective intervals configured according to the user's preference. Although it is typical to set the synchronization interval to 5 minutes, 15 minutes, 30 minutes, 1 hour, 4 hour, or the like, the synchronization interval for each application maybe set freely according to the user's intention. If the user wants to receive the data updated in real time, it is preferred to set the synchronization interval to a small value. Otherwise, if the user wants to conserve the communication resource and battery power, it may be preferred to set the synchronization interval to a longer interval.

The enhanced terminal transmits an updated data request message to the network entity (server) at an interval configured for the corresponding application. In response to the updated data request message, the server transmits the requested data to the enhanced terminal.

If the enhanced terminal is not in the state requiring communication, it is preferred to operate in an idle mode to reduce power consumption. Whenever the individual applications perform an update, the terminal has to transition from the idle mode to an active mode. Accordingly, if a plurality of applications are running with their respective synchronization intervals, the transition between the idle mode and the active mode may occur frequently. Likewise, if an application is running at least two repetitive operations configured, with two different synchronization intervals, this also causes the same problems as the at least two applications running with different synchronization intervals.

FIG. 1 is a diagram illustrating a synchronization process in a technology according to the related art.

Referring to FIG. 1, accounts, A, B, and C are registered with the mail client. Each account is configured to perform synchronization operation at an interval of 15 minutes. The account A starts the synchronization operation at time 3600 seconds and ends the synchronization operation at time 3605 seconds. An alarm is registered to start the synchronization operation for the account A after 15 minutes since the time of the end of synchronization. Afterward, the synchronization operation for account A restarts at time 4505 seconds. Similar operations are performed for accounts B and C.

After 8 seconds since the first synchronization operation for account A ends, the synchronization operation for account B restarts. In the entire synchronization process for one application, i.e. the mail client, the idle times between two consecutive synchronization operations are 8 seconds, 5 seconds, 14 minutes 35 seconds, 10 seconds, and 14 minutes and 33 seconds.

According to the conventional technology as described above, when a plurality of accounts are registered with the mail client and the accounts are configured with different synchronization intervals, the accounts have to perform synchronization at different times. Accordingly, the application (mail client) running on the terminal has to perform the synchronization operations of the plural accounts irregularly and non-periodically. In this case, the terminal has to transition between the idle mode and active mode for every synchronization operation. As the number of mode transition times increases, this increases the signaling overhead and power consumption. For example, in the 3rd Generation (3G) Wide Band Code Division Multiple Access (WCDMA) system, 35 controls messages are exchanged for Preservation mode transition and Radio Access Bearer (RAB) reconfiguration.

Accordingly, a method for synchronizing applications efficiently is desired.

The above information is presented as background information only to assist with an understanding of the present disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the present disclosure.

SUMMARY

Aspects of the present disclosure are to address at least the above-mentioned problems and/or disadvantages and to provide at least the advantages described below. Accordingly, an aspect of the present disclosure is to provide a method for synchronizing applications efficiently.

In accordance with an aspect of the present disclosure, an application synchronization method of a terminal is provided. The application synchronization method includes acquiring an alarm registration request of a first repetitive synchronization operation, acquiring a next execution time of a second repetitive synchronization operation associated with a same application as an application of the first repetitive synchronization operation, adjusting, when a difference between an alarm time of the alarm registration request of the first repetitive synchronization operation and the next execution time of the second repetitive synchronization operation is less than or equal to a threshold value, the alarm time of the alarm registration request of the first repetitive synchronization operation according to the next execution time of the second repetitive synchronization operation, and registering the adjusted alarm time.

In accordance with another aspect of the present disclosure, a terminal is provided. The terminal includes a control unit configured to acquire an alarm registration request of a first repetitive synchronization operation and a next execution time of a second repetitive synchronization operation associated with a same application as an application of the first repetitive synchronization operation, to adjust, when a difference between an alarm time of the alarm registration request of the first repetitive synchronization operation and the next execution time of the second repetitive synchronization operation is less than or equal to a threshold value, the alarm time of the alarm registration request of the first repetitive synchronization operation according to the next execution time of the second repetitive synchronization operation, and to register the adjusted alarm time and a communication unit configured to transmit and receive data necessary for synchronization under the control of the control unit.

FIG. 2 is a block diagram illustrating a configuration of a terminal 200 according to an embodiment of the present disclosure.

Referring to FIG. 2, the terminal 200 according to an embodiment of the present disclosure includes a communication unit 210, a control unit 220, and a storage unit 230. The control unit 200 controls overall operations of the terminal 200 according to one of the following various embodiments. Particularly in an embodiment, the control unit 220 estimates the intervals of individual repetitive synchronization operations and adjust the start times of the synchronization operations based on the estimation result according to an embodiment of the present disclosure. The control unit 220 stores the data necessary for use in adjusting the start times of the synchronization operations in the storage unit 230. The communication unit 210 communicates with a network entity such as server to exchange the data and/or signal necessary for use in the synchronization operation under the control of the control unit 220.

Although not illustrated in FIG. 2, the terminal 200 may further include an input unit for receiving a key input and/or touch input made by the user and/or a display unit for displaying/presenting information to the user.

Descriptions are made of the detailed operations of the components of the terminal of FIG. 2 in detail hereinafter with reference to FIGS. 3 to 7.

FIG. 3 is a diagram illustrating a configuration of an operating system of the control unit 220 according to an embodiment of the present disclosure.

Referring to FIG. 3, the operating system of the control unit 220 includes an application layer 310, an application framework layer 320, a system library layer 330, and a kernel layer 340.

The application layer 310 is the layer on which applications 315 are running. The application framework layer 320 is a set of classes and libraries implementing application program standard structure for a specific operating system. That is, the application framework 320 manages the lifecycle of the application 315 and provides event handling and application control function. The application framework layer 320 may include the alarm manager 325 which requests for synchronization of the update period of the application 315.

The system library layer 330 is a set of data sets and files sets memorizing the parts of the operating system. The system library layer 330 includes a synchronization scheduler 335 for synchronizing the synchronization interval of the application 315 running on the application layer 310.

The kernel layer 340 is a core responsible for interrupt handling, process management, memory management, and system management, and proving programming interface and basic functions of the operation system. Accordingly, the kernel 340 is loaded in the memory to which normal access is barred. That is, the kernel may be considered as an application for controlling hardware.

The above layer-structured control unit 220 may operate as follows.

The application layer 310 sends the application framework layer 320 a synchronization period registration request for synchronization operation of the registered application 315 at operation 350. The alarm manager 325 requests the synchronization scheduler 335 to add an alarm item to the alarm list at operation 355. This process is performed repeatedly whenever the synchronization operation is registered at operation 357.

An optimal synchronization calculator 360 of the synchronization scheduler 335 calculates a synchronization interval of the repetitive synchronization operation associated with the requested synchronization operation requested according to the following embodiment and adds the calculated synchronization interval to the alarm list 365 at operation 363. The synchronization scheduler 335 determines the scheduling synchronization interval stored in the alarm list at operation 367, and the alarm processor 370 determines the alarm interval for alarming the application layer 310. When the alarm time arrives, the synchronization scheduler 335 alarms the application layer 310 of the synchronization alarm of the application at operation 375.

The optimal synchronization calculator 360 may adjust the start times of the synchronization operations of the same application such that the synchronization operations are processes at the same timing and/or consecutively.

The optimal synchronization calculator 360 may be a component of the synchronization scheduler 335 and/or an independent component separated from the synchronization scheduler 335.

FIG. 4 is a diagram illustrating a configuration of an alarm list according to an embodiment of the present disclosure.

Referring to FIG. 4, the alarm list that is stored in the storage unit 230 includes a record 410 corresponding to each repetitive synchronization operation. One record 410 corresponds to one repetitive synchronization operation. Each record may include a type field 415, a start time (when) field 417, and a scheduling synchronization interval (repeat interval) field 419. The type field 417 contains the information on the method for configuring the alarm notifying of the update interval with the information on whether to use absolute time (UTC) and/or relative time (e.g. after 5 minutes and 10 minutes). The information contained in the type field 415 represented by ELAPSED_REALTIME_WAKEUP or RTC_WAKEUP. The ELAPSED_REALTIME_WAKEUP is the information for use in determining the alarm trigger time since the current time. RTC_WAKEUP is the time acquired from the network for use in determining the alarm trigger time based on the absolute time.

The start time 417 denotes the time for starting the first synchronization operation of the repetitive synchronization operation since the repetitive synchronization operation's registration. The repeat interval 419 is the information on the interval of the repetitive synchronization operation.

Each record 410 may include the identifier for use in identifying the repetitive synchronization operation corresponding thereto. The record 410 may include a final synchronization time of the corresponding repetitive synchronization operation.

According to an alternative embodiment, some fields may be stored in different records other than all of the fields as illustrated in FIG. 4 are stored in one record. In this case, the two records having the same repetitive synchronization operation identifier may be combined into one record to give an effect of the record as illustrated in FIG. 4.

If the application 315 is running with a plurality of repetitive synchronization operations, the application 315 sends the synchronization scheduler 335 an alarm registration request whenever the synchronization operation is required. The alarm registration request includes the repetitive synchronization operation identifier, but not any information on the interval. If the alarm time arrives, the synchronization scheduler 335 sends the application 315 the synchronization operation start notification including the information exemplified in Table 1. The synchronization operation start notification is also referred to as an alarm notification.


TABLE 1
alarm-registered repetitive synchronization operation identifier
Sync Status Info
First repetitive synchronization
First final synchronization time
operation identifier
Second repetitive
Second final synchronization
synchronization operation
time
identifier
Third repetitive synchronization
Third final synchronization time
operation identifier
. . .
. . .

The alarm-registered repetitive synchronization operation identifier is the identifier of the repetitive synchronization operation of which synchronization time has currently arrived. That is, if any of the alarm identifiers of Table 1 is received, the application 315 performs synchronization operation corresponding to the alarm-registered repetitive synchronization operation identifier. In a case of the mail client application, the repetitive synchronization operation for a specific account may be identified using one repetitive synchronization operation identifier. The repetitive synchronization operation of another account may have another unique repetitive synchronization operation identifier.

In addition, the notification of Table 1 includes the information on the alarm-registered repetitive synchronization operation and other synchronization operations. The notification of Table 1 stores the identifiers of the respective synchronization operations in association with the last synchronization times (e.g. completion time) of the repetitive synchronization operations corresponding to the identifiers. The information of Table 1 is characterized in that if the synchronization scheduler 335 cannot read the information of Table 1 at the time when the alarm registration is requested initially, i.e. when other applications with the exception of the application 310 which has registered the alarm cannot read the alarm, the synchronization scheduler 335 may be allowed to read the information of Table 1 when the feedback (re-notification) information of the successful notification completion with the generation of the alarm notification. If the synchronization scheduler 335 is able to read the information at the time when the alarm registration is requested, the information of Table 1 may be read at the time when the alarm registration is requested.

FIG. 5 is a diagram illustrating the synchronization procedure according to an embodiment of the present disclosure.

In the embodiment of FIG. 5, the application 315 is a mail client. The mail client 315 has three accounts (accounts A, B, and C) registered therewith. The accounts are configured to perform synchronization at an interval of 15 minutes at the application level. However, the alarm registration request message transmitted from the application 315 to the synchronization scheduler 335 does not include the information on the interval as described above. Accordingly, it is necessary for the synchronization scheduler 335 and/or a separate component to estimate the individual repetitive synchronization operation intervals. The synchronization operation interval estimation procedure is described with reference to FIG. 6.

FIG. 6 is a flowchart illustrating a synchronization interval estimation procedure according to an embodiment of the present disclosure.

Referring to FIG. 6, the control unit 220 acquires a synchronization operation start notification including the information in the form as exemplified in Table 1 or similar information at operation 610. The synchronization operation start notification includes the information on the final operation end times of other synchronization operations as well as the information on the start time of the corresponding synchronization operation.

Referring to FIG. 5, a synchronization operation of account A starts at time 3600 seconds and ends at time 3605 seconds. At the synchronization start time 3600 seconds of account A, the control unit 220 may acquire the synchronization start notification. The control unit 220 acquires the status information of all the synchronization operations of the corresponding application from the synchronization operation start notification at operation 620. For example, the control unit 220 may acquire the information on the times when the synchronization operations of accounts A, B and C have completed from the synchronization operation start notification.

The control unit 220 determines whether there is any record on the final synchronization time of the synchronization start notification target repetitive synchronization operation at operation 630. The control unit 220 may determine the corresponding repetitive synchronization operation, e.g. final synchronization time of account A, from the synchronization start notification of Table 1. According to an alternative embodiment, the control unit 220 may record the synchronization time at operation 660 and determine the final synchronization time of account A using the recorded synchronization time. The control unit 220 may also determine the final synchronization time in the synchronization start notification and the final synchronization time recorded at operation 660 to take the latest one of the two final synchronization times. In the following description, it is assumed that both the final synchronization time indicated in the synchronization start notification and the final synchronization time recorded at operation 660 are used.

If there is no final synchronization time of the repetitive synchronization operation of account A in the synchronization start notification and there is no final synchronization time of the repetitive synchronization operation of account A which has been recorded at operation 630, the procedure goes to operation 660. At operation 660, the control unit 220 records the final synchronization time of account A. The final synchronization time may be one of the time when the corresponding synchronization start notification has been generated, the time when the repetitive synchronization operation has actually started, and the time when the repetitive synchronization operation has actually ended. In the case of recording the time when the repetitive synchronization operation ends, the control unit 220 may wait for the end of the synchronization operation and records, when the final synchronization operation has completed, the final synchronization time.

If the final synchronization time of the repetitive synchronization operation of account A is acquired from the synchronization start notification and the information recorded at operation 630, the procedure goes to operation 640.

At operation 640, the control unit 220 acquires and stores the synchronization interval estimation value using the synchronization start notification occurrence time and the final synchronization time of the corresponding repetitive synchronization operation. For example, if the value obtained by subtracting the final synchronization time of the corresponding repetitive synchronization operation from the synchronization start notification occurrence time may be the synchronization interval estimation value. The synchronization interval estimation value may be stored in the record as illustrated in FIG. 4. Also, in the cast that the synchronization scheduler 335 reads the information of Table 1 at the time when the alarm registration is requested, the difference between the time when the synchronization start notification occurs, i.e. next execution time of the corresponding synchronization operation, and the last synchronization time of the corresponding repetitive synchronization operation may become the synchronization estimation value of the corresponding repetitive synchronization operation.

At operation 650, the control unit 220 acquires and store the next synchronization time using the synchronization interval estimation value. For example, if the synchronization operation of account A ends at the time 3605 seconds and if the synchronization interval estimation value is 15 minutes (=900 seconds), the next synchronization time is (end time)+(interval estimation value)=4505 seconds. For example, the next synchronization time may be stored in the record as illustrated in FIG. 4. According to an alternative embodiment, the next synchronization may be estimated as (start time)+(interval estimation value). Afterward, operation 660 is performed as described above.

Through the procedure of FIG. 6, the final synchronization time of the repetitive synchronization operation is stored. If the corresponding repetitive synchronization operation has been performed previously, it is possible to acquire the synchronization interval estimation value and the next synchronization time estimation value. In the embodiment of FIG. 5, the same procedure may be perform for both the synchronization operation of account B starting at the time 3613 seconds and the synchronization operation of account C starting at the time 3625 seconds.

The embodiment of FIG. 6 shows an interval estimation procedure and may be replaced by a similar method of acquiring at least two synchronization operation execution times and difference between the two times.

FIG. 7 is a flowchart illustrating an alarm configuration procedure according to an embodiment of the present disclosure.

Referring to FIG. 7, the control unit 220 detects the synchronization alarm registration request output by the application 315 at operation 710. As described above, the synchronization alarm request includes only the repetitive synchronization operation identifier and synchronization time but not the interval information. For example, after the synchronization operation of account B has completed at the time 3620 seconds, the application 315 sets the synchronization operation time by adding the synchronization interval of 15 minutes (=900 seconds) to the end time, i.e. 4520 (=3620+900), and sends the synchronization alarm registration request to the synchronization scheduler 335.

At operation 720, the control unit 220 acquires the information on the other synchronization operation(s) of the same application. For example, a description is made of the case where an alarm registration request of the synchronization operation having the repetitive synchronization operation identifier is generated. For example, it is possible to acquire the next synchronization operation time 4505 seconds of the repetitive synchronization operation of account A at the synchronization operation end time 3620 seconds of account B. Also, it is possible to acquire the next synchronization operation time 4505 seconds or 4510 seconds of the repetitive synchronization operation of account A at the synchronization operation end time 3630 of account C.

At operation 730, the control unit 220 compares the synchronization alarm registration request time, i.e. the time 4520 seconds included in the alarm registration request of account B, and the next synchronization estimation time 4505 seconds (or 4510 seconds) of account B to determine whether the difference between two values is in the range of a determined threshold value. Assuming that the threshold value is 20, since the difference between the time values are 15 seconds which is less than the threshold value of 20 seconds, the procedure goes to operation 740. The comparison process is performed for all of the repetitive synchronization operations of the same application. If the difference between two values is greater than the threshold value, the alarm is registered without any adjustment.

At operation 740, the control unit 220 adjusts the synchronization alarm time requested for registration. For example, the control unit 220 may adjusts the next synchronization notification time of account B to be at 4505 seconds, identical with the next synchronization alarm time of account A. However, if the two synchronization operations cannot be performed simultaneously, the control unit 220 waits for the time (4510 seconds) when the synchronization operation of account A ends and notifies the application of the repetitive synchronization operation of account B. The control unit 220 may adjusts the synchronization operation execution time of account B such that the synchronization operation of account B is performed at the same time as or immediately after (within a time difference value) the synchronization operation of account A in a similar manner.

At operation 750, the control unit 220 adjusts the synchronization interval estimation value according to the result from operation 740. For example, since the synchronization operation of account B ends at time 3620 seconds and the next synchronization operation starts at time 4505 seconds, the synchronization interval estimation value becomes 885 seconds (=15 minutes−15 seconds). In the case that the next synchronization operation is configured to start at time 4510 seconds, the synchronization interval estimation value becomes 890 seconds (=15 minutes−10 seconds). The adjusted synchronization interval estimation value is store in the storage unit 230 in the form of a record as illustrated in FIG. 4.

According to the above procedure, in the case that an application is performing a plurality of synchronization operations as shown in FIG. 5, the control unit 220 may estimate that the synchronization interval of each repetitive synchronization operation is about 15 minutes through experimental learning. The control unit 220 also may identify the individual synchronization operation based on the estimated synchronization operation interval and control the start times of the plural repetitive synchronization operations such that the synchronization operations are performed simultaneously or at similar intervals (within an error range of α,β, α′, and β′).

As described above, when an application is running a plurality of repetitive synchronization operations without provision of information on the intervals of the repetitive synchronization operations, the control unit 220 estimates the synchronization intervals of the repetitive synchronization operations and controls the synchronization operation execution times such that the synchronization operations occur simultaneously or consecutively.

As a consequence, the application execution method of the present disclosure is capable of reducing the number of transitions between the idle and active modes which is caused by irregular synchronization operations of multiple applications or processes of the same application, thereby reducing unnecessary power consumption and the radio access network traffic load caused by frequent operation mode transmission without compromising the number of execution times of synchronization operations.

It will be understood that each block of the flowchart illustrations and/or block diagrams, and combinations of blocks in the flowchart illustrations and/or block diagrams, maybe implemented by computer program instructions. These computer program instructions may be provided to a processor of a general purpose computer, special purpose computer, or other programmable data processing apparatus to produce a machine, such that the instructions, which execute via the processor of the computer and/or other programmable data processing apparatus, create means for implementing the functions/acts specified in the flowchart and/or block diagram block and/or blocks. These computer program instructions may also be stored in a computer-readable memory that may direct a computer and/or other programmable data processing apparatus to function in a particular manner, such that the instructions stored in the computer-readable memory produce an article of manufacture including instruction means which implement the function/act specified in the flowchart and/or block diagram block and/or blocks. The computer program instructions may also be loaded onto a computer and/or other programmable data processing apparatus to cause a series of operational operations to be performed on the computer and/or other programmable apparatus to produce a computer implemented process such that the instructions which execute on the computer and/or other programmable apparatus provide operations for implementing the functions/acts specified in the flowchart and/or block diagram block and/or blocks.

Furthermore, the respective block diagrams may illustrate parts of modules, segments and/or codes including at least one or more executable instructions for performing specific logic function(s). Moreover, it should be noted that the functions of the blocks may be performed in different order in several modifications. For example, two successive blocks may be performed substantially at the same time, or may be performed in reverse order according to their functions.

The term “module” according to the various embodiments of the disclosure, means, but is not limited to, a software and/or hardware component, such as a Field Programmable Gate Array (FPGA) or Application Specific Integrated Circuit (ASIC), which performs certain operations. A module may advantageously be configured to reside on the addressable storage medium and configured to be executed on one or more processors. Thus, a module may include, by way of example, components, such as software components, object-oriented software components, class components and operation components, processes, functions, attributes, procedures, subroutines, segments of program code, drivers, firmware, microcode, circuitry, data, databases, data structures, tables, arrays, and variables. The functionality provided for in the components and modules may be combined into fewer components and modules or further separated into additional components and modules. In addition, the components and modules may be implemented such that they execute one or more CPUs in a device and/or a secure multimedia card.

The terminal or mobile terminal according to an embodiment of the present disclosure may be implemented in any of various types of portable electronic devices including mobile phone, Personal Digital Assistant (PDA), navigation device, digital broadcast receiver, and Portable Multimedia Player (PMP).

It is to be appreciated that those skilled in the art may change or modify the various embodiments without departing the technical concept of this disclosure. Accordingly, it should be understood that above-described various embodiments are essentially for illustrative purpose only but not in any way for restriction thereto. Thus the scope of the disclosure should be determined by the appended claims and their legal equivalents rather than the specification, and various alterations and modifications within the definition and scope of the claims are included in the claims.
