Description

TECHNICAL FIELD [0001] The present invention relates to a mobile terminal, a service server, and an IMS status information registration method.

One embodiment of the present invention relates to a technique for effectively transferring status information regarding SIP and IMS applications for use of an IMS service to a service server.

2. Description of the Related Art In general, an IP Multimedia Subsystem (hereinafter, referred to as 'IMS') is a system for providing an IP (Internet Protocol) based packet communication service. The IMS service is based on a Session Initiation Protocol (SIP), which is a text-based application layer control protocol.

The SIP is based on a client / server architecture in which a server responds when clients initiate a call. Accordingly, the IMS service provides a high-speed packet data service capable of transmitting e-mail, still images, and large-capacity digital multimedia data to a portable terminal as well as an existing voice call service. For example, the IMS service provides a myriad of additional services such as a messenger service, a video call service, and a PoC service.

Meanwhile, with the activation of the IMS service, a portable terminal equipped with the IMS platform as a base is being released. The portable terminal periodically registers SIP in the IMS server to use the IMS service. Therefore, in order to provide the IMS service, the portable terminal requests communication to the IMS server constantly at a specific time regardless of the intention of the user. That is, the portable terminal uses not only the resources of the terminal itself but also the resources of the network.

In addition, when using any one of the IMS services, the portable terminal periodically transmits status information (ON / OFF) regarding the IMS service in use to the IMS server. This is because, if the IMS server can not receive the status information in time, it forcibly terminates the IMS service being provided to the portable terminal.

However, since the amount of status information to be transmitted periodically increases as the number of available IMS services increases, the portable terminal uses a large amount of network resources as well as resources of the terminal itself.

Accordingly, there is a need for a method for efficiently transmitting status information in a portable terminal providing the IMS service.

One embodiment of the present invention is a portable terminal including a mobile terminal and a network resource for efficiently using the mobile terminal and the network resource by including the status information about the IMS application being executed in the SIP registration message at a time to the service server, Provides a method for registering IMS status information.

An embodiment of the present invention adjusts the first period or the second period in consideration of the arrival time of the second period and the arrival time of the first period in which the registration message is created based on the execution start time of the IMS application And transmitting the registration message for SIP registration to the service server by including the status information together with the registration message for SIP registration, and an IMS status information registration method.

1 is a diagram illustrating a network connection relationship between a portable terminal, a service server, and an IMS server according to an embodiment of the present invention.

Referring to FIG. 1, the portable terminal 110 generates a registration message for SIP registration to the service server 120 according to a first cycle. The portable terminal 110 periodically transmits the created registration message to the service server 120 via the base transceiver station (BTS) and the packet data serving node (PDSN) according to the first period, IMS can provide a basis for using IMS services.

SIP is a Session Initiation Protocol (SIP), and is a text-based application layer control protocol for providing IMS services. Here, the IMS (IP Multimedia Subsystem) is a system for providing an IP (Internet Protocol) based packet communication service.

This SIP is based on a client / server architecture where the server responds when the clients initiate the call. Accordingly, the IMS service provides a high-speed packet data service capable of transmitting e-mail, still images, and large-capacity digital multimedia data to a portable terminal as well as an existing voice call service.

For example, the IMS service provides a myriad of additional services such as a messenger service, a video call service, and a PoC service. The IMS service may include an IMS server for providing each additional service, and the IMS server may include a messenger server 130, a PoC server 140, and a video chat server 150. The service server 120 may control the IMS server to provide the IMS service to the portable terminal 110. [ As described above, the service server 120 includes a CSCF (Call Session Control Function) server as an IMS core platform.

When the IMS application providing the IMS service is executed by the user, the portable terminal 110 generates status information on the IMS application being executed. The IMS application refers to an application providing each IMS service such as a messenger service, a video call service, and a PoC service. The status information relates to whether the IMS service is used through the IMS application, for example, the service use (ON) or the service use OFF (OFF). Like the registration message, the portable terminal 110 periodically transmits the status information to the service server 120 via the BS and the PDSN from the start of execution of the IMS application.

In this case, conventionally, there has been a problem in that not only the resources of the portable terminal but also the resources of the network are used much by transmitting the registration message and the status information separately according to different periods. This is because the first period for generating the registration message is different from the second period for generating the status information.

However, the portable terminal 110 of the present invention transmits the registration message and the status information at once to the service server 120 by including the status information in the registration message, thereby transmitting not only the resources of the portable terminal itself but also the resources Can be efficiently used.

For example, the period for generating the registration message may be a 'first period', and the period for generating status information of an IMS application providing a messenger service may be a 'second period'.

When the IMS application providing the messenger service is executed for the first time, the portable terminal 110 can generate the status information (ON) at the start of execution of the IMS application and transmit the status information to the service server 120. In this case, the service server 120 can notify the messenger server 130 that the portable terminal 110 is using the messenger service by transmitting the transmitted status information ON to the messenger server 130. [

Thereafter, the portable terminal 110 generates the state information at an arrival time point of the second cycle determined based on the execution start time, and transmits the state information to the service server 120 by including the generated state information in the registration message . To this end, the portable terminal 110 may synchronize the second period in the first period or synchronize the first period in the second period. That is, the portable terminal 110 can integrate the first and second periods into one, and transmit the registration message and the status information to the service server 120 at a time.

The service server 120 periodically receives a registration message from the portable terminal 110 and extracts status information from the received registration message. The service server 120 transmits the extracted status information to the messenger server 130 so that a stable messenger service can be provided to the portable terminal 110.

At this time, the service server 120 may maintain the messenger service provision to the portable terminal 110 by the messenger server 130 until the arrival of the first period even if the first period and the second period are different from each other, (130). That is, when the arrival time of the second cycle is earlier than the arrival time of the first cycle, even if the registration message is not received until the arrival time of the second cycle, the service server 120, The server 130 may control the portable terminal 110 to provide a messenger service.

2 is a block diagram illustrating a configuration of a portable terminal according to an embodiment of the present invention.

2, the portable terminal 200 may include a message creator 210, a status information control module 220, and an IMS platform 230.

The message creation unit 210 creates a registration message for SIP registration to the service server 120 according to the first cycle. SIP is a session initiation protocol, a text-based application layer control protocol for providing IMS services. That is, the SIP registration is for providing a basis for the portable terminal 200 to use the IMS service.

Here, when power is applied to the portable terminal 200 and the registration message for the SIP registration is created for the first time, the IMS platform 230 transmits the registration message to the service server 120 via the base station and the PDSN . When the IMS platform 230 transmits the registration message created according to the first period, the IMS platform 230 may transmit the registration message including status information on the IMS application using the IMS service.

The status information control module 220, when the IMS application is executed by the user, generates status information regarding the IMS application being executed. The IMS application refers to an application providing each IMS service such as a messenger service, a video call service, and a PoC service. The status information relates to whether the IMS service is used through the IMS application, for example, the service use (ON) or the service use OFF (OFF). The status information, like the registration message, should be periodically transmitted to the service server 120 from the start of execution of the IMS application.

In an embodiment, the status information control module 220 may generate the status information at the start of execution of the IMS application. Then, the state information control module 220 can generate the state information at an arrival time point of the second cycle determined based on the execution start time of the IMS application.

At this time, if the status information is generated for the first time, the IMS platform 230 transmits the generated status information to the service server 120 via the base station and the PDSN alone without including the generated status information in the registration message.

However, after this, the IMS platform 230 may transmit the status information to the service server 120 by including the status information in the registration message.

Because the first period for generating a registration message and the period for transmitting status information are generally different from each other, conventionally, the registration message and the status information are transmitted in different periods, respectively, so that not only the resources of the portable terminal itself, There was a problem that a lot of resources were used.

In order to solve this problem, the IMS platform 230 of the present invention transmits the registration message and the status information at once to the service server 120 by including the status information in the registration message, Thereby enabling efficient use of resources of the network as well as resources.

In the present invention, the cycle of generating the registration message is 'first cycle', and the cycle of generating the state information of the IMS application is described as a 'second cycle'.

The message creator 210 may generate the registration message for each arrival time of the first period. Alternatively, the IMS platform 230 may continue to use the initially created registration message.

The state information control module 220 generates state information about the IMS application at each time point of the second cycle.

Since the first and second periods may be different from each other, the state information may be included in the registration message by appropriately adjusting the first period and the second period, An embodiment will be described.

In the first embodiment, when the arrival time of the second cycle is earlier than the arrival time of the first cycle, the IMS platform 230 stores the state information generated at the arrival time of the second cycle in the temporary buffer, When the registration message is created in the first period, the state information may be included in the created registration message and transmitted to the service server 120. That is, the IMS platform 230 may transmit the state information included in the registration message according to a first period when the registration message is created.

In another embodiment, the IMS platform 230 controls the state information control module 220 when the arrival time of the first cycle is earlier than the arrival time of the second cycle, And to generate the state information in the first period. Therefore, the status information control module 220 can generate the status information according to the first period, rather than the second period. As a result, when the status information is generated, the IMS platform 230 may transmit the generated status information to the service server 120 in the registration message. At this time, the IMS platform 230 may transmit the state information to the registration message in the first period, which is the time when the registration message is created.

That is, if the arrival time of the first period is different from the arrival time of the second period, the IMS platform 230 can transmit the state information to the registration message according to the first period.

In the second embodiment, when the arrival time of the second period is earlier than the arrival time of the first period, the IMS platform 230 controls the message creation unit 210 to update the message So that the registration message can be generated in the second cycle. Accordingly, the message creator 210 may generate the registration message according to the second period instead of the first period. As a result, when the registration message is generated, the IMS platform 230 may transmit the generated state information to the service server 120 by including the generated state information in the registration message. At this time, the IMS platform 230 may transmit the state information to the registration message according to the second period, which is the time point at which the state information is generated. Thereafter, the IMS platform 230 adjusts the first period at a time interval of the second period so that the message creation unit 210 can create the registration message according to the adjusted first period.

That is, when the arrival time of the first period is different from the arrival time of the second period, the IMS platform 230 adjusts the first period in consideration of a time point ahead of time, The state information may be included in the registration message so as to be transmitted.

Hereinafter, an example of adjusting the first period when two IMS applications are executed will be described with reference to FIG.

3 is a diagram illustrating an example of adjusting a period to transmit registration messages and status information for SIP registration at a time.

Referring to FIG. 3, a period for generating a registration message is a 'first cycle', a cycle for generating first state information of a first IMS application is a 'second cycle', a second state information of a second IMS application Is described as a " third cycle ". The second period may be determined based on the first execution start time of the first IMS application and the third period may be defined based on the second execution start time of the second IMS application.

When the first and second IMS applications are executed for the first time, the status information control module 220 generates the first and second status information at the start of execution of the first and second IMS applications, respectively. Thereafter, the state information control module 220 may control the generation of the first and second state information according to the control of the IMS platform 230.

For example, if the first arrival time of the second period for the first IMS application is earlier than the first arrival time of the first period, the IMS platform 230 adjusts the first period to the second period (310) . In this case, the message creation unit 210 creates the registration message in the adjusted first period, and the state information control module 220 generates the first state information in the second period, so that the IMS platform 230 And may transmit the first state information to the service server 120 by including the first state information in the registration message at the first arrival time of the second period.

In an embodiment, the IMS platform 230 may adjust the time interval of the adjusted first period to a time interval of the second period, or may maintain the time interval of the first period as it is. For example, if the time interval of the first cycle is '1 hour', the time interval of the second cycle is '25 minutes', the first arrival time of the first cycle is '13:00' 12: 45 ', the IMS platform 230 changes the first period to' 12:45 'in accordance with the second period, and thereafter changes the arrival time interval of the first period to '25: 45' Quot ;, or the arrival time interval of the first cycle may be maintained as '1 hour'.

In this case, when the arrival time interval of the first period is adjusted to '25 minutes', the second arrival time of the first period is '13:10'. Accordingly, the IMS platform 230 can transmit the registration message including the first status information to the service server 120 according to a first period that comes every '25 minutes'.

However, if the arrival time interval of the first cycle is maintained at '1 hour', the second arrival time of the first cycle is '13:45'. Accordingly, the IMS platform 230 may transmit the first state information to the service server 120 by including the first state information in the registration message according to a first period that comes every '1 hour'.

Alternatively, if the first arrival time of the second period for the first IMS application is earlier than the first arrival time of the first period, the IMS platform 230 adjusts the second period to the first period (320 ). In this case, the state information control module 220 generates the first state information in the first period instead of the second period, and the message creation unit 210 normally creates the registration message in the first period, The control unit 230 may transmit the first state information to the service server 120 by including the first state information in the registration message at the first arrival time of the first period.

Alternatively, if the first arrival time of the second cycle is ahead of the first arrival time of the first cycle, and the first arrival time of the first cycle is earlier than the first arrival time of the third cycle of the second application, The IMS platform 230 adjusts the second and third periods to the first period (330). In this case, the state information control module 220 may generate the first state information in the first period instead of the second period, and generate the second state information in the first period, which is not the third period. Accordingly, the IMS platform 230 may include both the first status information and the second status information in the registration message at the first arrival time of the first period and transmit the registration message to the service server 120.

The IMS platform 230 may then control the status information control module 220 to cause the status information control module 220 to generate all of the first and second status information according to the first period. Accordingly, the IMS platform 230 may transmit the first state information and the second state information to the service server 120 in the registration message according to the first period.

Thus, the portable terminal 200 of the present invention can transmit the registration information for the SIP registration to the service server at once including the status information about the IMS application being executed, thereby efficiently using the portable terminal and the network resources .

However, when the registration message includes the status information, the service server 120 extracts the status information from the registration message and transmits the status information to the corresponding IMS server.

4 is a block diagram illustrating a configuration of a service server according to an embodiment of the present invention.

Referring to FIG. 4, the service server 400 may include an information extracting unit 410 and an information controlling unit 420.

The information extracting unit 410 receives the registration message from the portable terminal 200 and extracts the status information from the received registration message.

Conventionally, since the service server has separately received the registration message and the status information, the service server does not perform the process of extracting the status information from the registration message. However, in the present invention, since the registration message includes the state information, the state information is extracted from the registration message and the extracted state information is transmitted to the corresponding IMS server.

5 is a diagram showing an example of a registration message including status information.

5, the information extracting unit 410 determines whether or not the status information 520 is included in the registration message in addition to the SIP registration information 510. If the status information 520 is included in the registration message, (520) can be extracted.

The status information 520 relates to whether the portable terminal 200 is in use (ON or OFF) with respect to the IMS application being executed. Thus, the status information may vary depending on the type of IMS application.

The information extracting unit 410 may extract the first state information 530, the second state information 540, and the third state information 550 from the state information 520.

The information control unit 420 transmits the extracted state information 520 to the IMS server associated with the IMS application. The IMS service provides a myriad of additional services such as messenger service, video call service, and PoC service. The IMS service may include an IMS server for providing each additional service, and the IMS server may include a messenger server 130, a PoC server 140, and a video chat server 150.

For example, the information control unit 420 may determine that the first state information 530 is related to 'IM (Instant Messenger)', and may transmit the first state information 530 to the instant messenger server 130.

Alternatively, the information control unit 420 determines that the second state information 540 is related to 'PoC (Push to talk over Cellular)' and transmits the second state information 540 to the PoC server 140 .

Alternatively, the information control unit 420 may determine that the third state information 550 is related to the 'VT chatting', and may transmit the third state information 550 to the video chat server 150.

Accordingly, each IMS server receives the status information and enables the portable terminal 200 to maintain each IMS service provision.

As described above, the portable terminal 200 transmits the registration message and the status information according to a predetermined period, so that the portable terminal 200 can receive a desired IMS service normally. The registration message may include information on 'the arrival time of the first cycle' for creating the registration message.

Therefore, the information control unit 420 controls the IMS server to maintain the IMS service provision by the IMS server until the arrival time of the first period. For example, even if the first period of the registration message and the second period of the first status information 530 are different from each other, the information control unit 420 transmits the registration message to the portable terminal 200 by the IMS server The IMS server can be controlled to maintain IMS service provisioning. That is, if the arrival time of the second cycle is earlier than the arrival time of the first cycle, even if the registration message is not received until the arrival time of the second cycle, the information control unit 420, The server 130 may control the portable terminal 200 to provide a messenger service.

This is because the IMS server transmits a stable IMS service to the portable terminal 200 even if the status information is not received according to the different status information periods by adjusting the periods to transmit the status information to the registration message at once .

6 is a flowchart illustrating a procedure of an IMS state information registration method according to an embodiment of the present invention.

Referring to FIG. 6, in step 601, the portable terminal 200 transmits a registration message for SIP registration to the service server 400 according to the first cycle. At this time, the registration message may include only SIP information for SIP registration. At this time, the portable terminal 200 can transmit the registration message to the service server 400 via the base station (BTS) and the PDSN.

In step 602, the service server 400 receives the registration message and registers the SIP of the portable terminal 200 using the SIP information included in the registration message. When the SIP is registered, the portable terminal 200 can provide a base for using the IMS service.

Thereafter, when the first IMS application is executed by the user, the portable terminal 200 transmits the first status information of the first IMS application to the service server 400 (Step 603). The portable terminal 200 may generate the first state information at an arrival time point of the second period determined based on the execution start time of the first IMS application or the execution start time point of the first IMS application.

In step 604, the service server 400 receives the first status information from the portable terminal 200 and transmits the received first status information to the corresponding IMS server. The service server 400 may transmit the first status information to the messenger server 130 when the first status information is related to the messenger service. Accordingly, the messenger server 130 may receive the first status information from the service server 400, and may provide the messenger service to the portable terminal 200.

When the arrival time of the first period is different from the arrival time of the second period, the portable terminal 200 may adjust the first period in consideration of a time point ahead of the arrival of the second period. Accordingly, the portable terminal 200 can generate a registration message in the first period and generate the first status information. The portable terminal 200 may include the first status information in the registration message.

Thereafter, in step 605, the portable terminal 200 transmits a registration message including the first status information and the SIP to the service server 400.

In step 606, the service server 400 receives the registration message from the portable terminal 200, extracts the first status information from the received registration message, and transmits the extracted first status information to the corresponding IMS server do.

Thereafter, when the second IMS application is executed by the user, in step 607, the portable terminal 200 transmits the second status information of the second IMS application to the service server 400. The portable terminal 200 may generate the second status information at an arrival time point of the third period determined based on the execution start time of the second IMS application or the execution start time point.

In step 608, the service server 400 receives the second status information from the portable terminal 200 and transmits the received second status information to the corresponding IMS server. The service server 400 may transmit the second status information to the PoC server 140 when the second status information is related to the PoC service. Accordingly, the PoC server 140 may receive the second status information from the service server 400, and may provide the PoC service to the portable terminal 200.

The portable terminal 200 may adjust the first period in consideration of a time point ahead of arrival when the arrival time of the adjusted first period differs from the arrival time of the third period. Accordingly, the portable terminal 200 can generate the registration message in the first period and generate the first and second status information. The portable terminal 200 may include all of the first and second status information in the registration message.

In step 609, the portable terminal 200 transmits the registration message including the first and second status information and SIP to the service server 400.

In step 610, the service server 400 receives the registration message from the portable terminal 200, extracts the first and second status information from the received registration message, and extracts the extracted first and second status information To each IMS server.

For example, the service server 400 may transmit the first status information to the messenger server 130 and transmit the second status information to the PoC server 140. Accordingly, the messenger server 130 provides the messenger service to the portable terminal 200, and the PoC server 140 can provide the PoC service to the portable terminal 200. [

7 is a diagram showing an example of comparison between a conventional IMS state information registration method and an IMS state information registration method of the present invention.

Referring to FIG. 7, the flow chart on the left is a conventional IMS state information registration method, and the flow chart on the right shows an IMS state information registration method of the present invention.

The conventional IMS state information registration method 710 and the IMS state information registration method 730 of the present invention transmit the registration message to the service server 400 when the SIP registration is to be performed for the first time.

When the IMS application is executed, the conventional IMS state information registration method 710 and the IMS state information registration method 730 according to the present invention can transmit state information (messenger, PoC, video chat) regarding the IMS application in the order of execution To the service server 400.

However, when the state information is transmitted for the second time, it can be seen that the conventional IMS state information registration method 720 and the IMS state information registration method 740 of the present invention are different. The conventional IMS status information registration method 720 transmits registration messages and status information (messenger, PoC, video chat) according to different periods as in the first 710. However, the IMS state information registration method 740 of the present invention can know that, unlike the first 730, only the registration message 750 is transmitted to the service server 400.

This is because the IMS status information registration method 740 of the present invention includes SIP information for SIP registration as well as status information (messenger, PoC, video chat) in the registration message 750, So that they do not separately transmit status information of different periods.

Therefore, the IMS state information registration method 740 of the present invention can efficiently use resources and network resources of the portable terminal 200, unlike the conventional IMS state information registration method 720.

The methods according to embodiments of the present invention may be implemented in the form of program instructions that can be executed through various computer means and recorded in a computer-readable medium. The computer-readable medium may include program instructions, data files, data structures, and the like, alone or in combination. The program instructions recorded on the medium may be those specially designed and constructed for the present invention or may be available to those skilled in the art of computer software.
