The present invention relates to a method and system for supporting handover, and more particularly, to a method and system for allowing handover of a mobile communication service between various terminals possessed by a user.

Recently, a single user has various portable terminals such as a smartphone, a tablet PC, a machine to machine (MTM) device in addition to a feature phone. Although these user terminals are equipped with hardware having different capabilities, they can be commonly supported by mobile communication companies such as voice call, SMS, data (Internet, video call, MMS, etc.) services.

Therefore, if there is a mobile communication service that is commonly supported by a plurality of terminals of one user, in certain circumstances, it may be desired to receive a service through one terminal based on a user. For example, when a plurality of different types of terminals owned by a user are subscribed to support voice call service, the terminals are all located at the same location, for example, in a house, an office, or a vehicle. In certain circumstances, a user may want to specify that only one of the terminals supports voice call service, but current technology does not support such user needs smoothly.

However, in order to hand over the mobile communication service supported by the user's terminal A to the terminal B, the user's own chip (USIM) can be mounted on the terminal B, but there is a problem in that the inconvenience.

Accordingly, an object of the present invention is to solve the above-described problem, and an object of the present invention is to allow a service handover to be automatically performed between various terminals possessed by a user, so that one or more terminals set to receive a designated service preferentially. The present invention provides a method and system for supporting an inter-terminal handover so that the mobile communication service can be supported through the MS.

Controlling handover of the mobile communication service to use a service (such as a voice call service, a text message service, or a data service) at another terminal.

The plurality of terminals may be equipped with a short-range communication module to determine adjacent or spaced apart from each other, and any one of the plurality of adjacent or spaced terminals may perform the service request.

The terminal using the handover target service among the plurality of terminals performs the service request.

A service usage priority of a plurality of terminals for a neighbor mode for each subscriber is maintained in the database, and a first terminal (a terminal for performing a service request and a terminal adjacent to a second terminal) among the plurality of terminals for the neighbor mode. And when the second terminal approaches, when the mobile communication service is handed over to the second terminal having a higher priority than the first terminal, or when the first terminal has the same priority as the second terminal, Both terminals can use the corresponding mobile communication service.

The service usage priority of the plurality of terminals for the subscriber-specific separation mode is maintained in the database, and among the plurality of terminals for the separation mode, a first terminal (terminal performing a service request) and a second terminal (first terminal) When the terminal is spaced apart from the terminal), when the mobile communication service is handed over to the second terminal having a higher priority than the first terminal, or the first terminal has the same priority as the second terminal. Both terminals can use the corresponding mobile communication service.

The service usage priority may be set differently for the plurality of divided mobile communication services in the database.

The database stores a service usage priority of subscriber identification information for distinguishing the plurality of terminals, and includes subscriber identification information (USIM information, telephone number, IP) included in the service request from the terminal performing the service request. Address, or MAC address).

And, according to another aspect of the present invention, the terminal-to-terminal handover support system for supporting handover of the terminal-to-terminal mobile communication service, priority setting for setting the service usage priority for a plurality of terminals for each subscriber in the database part; And a mobile communication used by any one of the plurality of terminals based on the service usage priority of the plurality of terminals of the subscriber with reference to the database with respect to a service request from any one of the plurality of terminals.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout.

1 is a diagram illustrating an inter-terminal handover support system 100 according to an exemplary embodiment of the present invention.

1, an inter-terminal handover support system 100 according to an embodiment of the present invention is a mobile communication service (eg, voice call, text message (SMS)) through a mobile communication network operated by a mobile communication service provider. One user has various user terminals such as feature phones, smartphones, tablet PCs, machine to machine (MTM) devices that support data (Internet, video call, LMS / MMS text message, etc.) In this case, if there is a mobile communication service supported by these user terminals in common, the customer management server 110 recognizes a specific situation and provides a service handover between terminals based on a user without changing a user unique chip (USIM). It was. The service handover is performed so that the mobile communication service of the terminal A of the user is performed only at the terminal B of the user according to the situation such as the proximity or separation between terminals, or in some cases the mobile communication service is performed only at the terminal A of the user. It means the movement of the mobile communication service to perform the service at the same time terminal and terminal B.

 The user terminal referred to in the present invention is a mobile communication service (eg, a core network) through which networks can be interworked according to protocols such as CDMA, WCDMA, WiFi, WiBro, wired / wireless Internet, and PSTN operated by a mobile communication service provider (eg , Voice calls, text messages (SMS), data (internet, video call, LMS / MMS text messages, etc.) services that can be used, in addition to smart phones (iPod, Android phones, etc.) (Cellular phone), PCS phone (Personal Communications Services phone), synchronous / asynchronous IMT-2000 (International Mobile Telecommunication-2000) capable of wireless communication, personal digital assistant (PDA), WAP (WAP) phone: may be a portable or mobile terminal such as a wireless application protocol phone, a mobile play-station, or a portable multimedia player (PMP); It may be a top PC, a Palm Personal Computer, or the like, and may include various electronic devices or devices throughout a home or industrial society, such as a Machine to Machine (MTM) device that may communicate with other electronic devices.

In order to support the handover of the user-to-terminal mobile communication service of the user, the customer management server 110 that can be operated in the form of a server on the network as described above, the priority setting unit 210, And a database 211, and a service controller (adjacent terminal service unit 220, spaced terminal service unit 230, and service setting unit 240).

First, the operation of the components of the customer management server 110 will be described briefly, and the operation of the inter-terminal handover support system 100 including the customer management server 110 will be described with reference to the flowcharts of FIGS. 5 to 7. I will explain in more detail.

The priority setting unit 210 sets the service use priority of the plurality of terminals for each subscriber in the database 211 according to an input of a user or an operator. Accordingly, the service control unit (neighboring terminal service unit 220, remote terminal service unit 230, and service setting unit 240), the service request from any one of the plurality of terminals of the subscriber, the database, Based on the service usage priority of the plurality of terminals of the subscriber with reference to 211, the handover of the mobile communication service is controlled so that the other terminal uses the mobile communication service used by one of the plurality of terminals.

As shown in FIG. 3 (in adjoining mode) and 4 (in separation mode), the database 211 stores service usage priority for subscriber identification information (eg, USIM information) for distinguishing a plurality of terminals for each subscriber. The service controller may determine the corresponding subscriber through the subscriber identification information included in the service request from the terminal (eg, the terminal using the handover target service) that performs the service request.

As described above, the database 211 includes a plurality of terminals (subscriber identification information) for each mobile communication service (eg, a voice call service, a text message service, or a data service). Service usage priority may be set differently with respect to the subscriber identification information. Here, the subscriber identification information may include USIM information (eg, terminal identification number (IMSI, MSISDN, etc.), unique serial number, etc.) of the Universal Subscriber Identification Module (USIM) installed in each terminal. For example, but not limited to, a phone number, an IP (Internet Protocol) address, a MAC (Media Access Control) address, or the like.

Each terminal of the user may be equipped with a short range wireless communication module (eg, Bluetooth, ZigBee, etc.) to determine the adjacent or separated from each other, any one of the terminals of the adjacent or spaced user to perform the above service request In particular, such a service request may be performed by a terminal using a handover target service, that is, a terminal which wants to handover a service to another terminal.

For example, as shown in FIG. 3, the service usage priority of a plurality of terminals for a neighbor mode for each subscriber may be set in the database 211, and the neighbor terminal service unit 220 may include a plurality of terminals for the neighbor mode. If there is an access between the terminals and there is a difference in priority between the two accessing terminals, for example, a higher priority than the first terminal (eg, a terminal performing a service request as a terminal adjacent to the second terminal). The second terminal may control the handover of the corresponding mobile communication service. In addition, when the first terminal has the same priority as the second terminal, the adjacent terminal service unit 220 may control both terminals to use the corresponding mobile communication service. For example, in the case of a voice call service, as shown in FIG. 3, the terminal equipped with the USIM (A) may have a higher priority than the terminal equipped with the USIM (B). In the separation mode, the terminal equipped with the USIM (B) may have a higher priority than the terminal equipped with the USIM (A).

In addition, for example, as shown in FIG. 4, the service usage priority of a plurality of terminals for a subscriber-specific separation mode may be set in the database 211, and the spaced terminal service unit 230 may configure the plurality of separation modes for the separation mode. If there is a gap between the terminals among the terminals of the terminal and there is a difference in priority between the two separated terminals, for example, a second terminal having a higher priority than the first terminal (eg, a terminal performing a service request) (eg, A terminal that is spaced apart from one terminal) may be controlled to perform handover of the corresponding mobile communication service. In addition, the separate terminal service unit 230 may control both terminals to use the corresponding mobile communication service when the first terminal has the same priority as the second terminal. For example, in the case of a voice call service, as shown in FIG. 4, the terminal equipped with the USIM (A) may have a higher priority than the terminal equipped with the USIM (B). In the adjacent mode, the terminal equipped with the USIM (B) may have a higher priority than the terminal equipped with the USIM (A).

On the other hand, according to the control of the handover of the adjacent terminal service unit 220 and the remote terminal service unit 230 as described above, the service setting unit 240 is a change history of the mobile communication service for the plurality of terminals of the subscriber (eg Information on the terminal currently using the service) can be set, and the change details are requested upon request of equipment (e.g., exchange, home location register, etc.) on the mobile communication network to relay the service on the mobile communication network according to the change details. It can be provided.

Hereinafter, the operation of the inter-terminal handover support system 100 including the customer management server 110 will be described in more detail with reference to the flowcharts of FIGS. 5 to 7.

5 is a flowchart illustrating a handover process when terminals are changed from a spaced state to an adjacent state.

First, in a state in which user terminals # 1 and # 2 are spaced apart from coverage of an adjacent mode (S110), for example, one or more of a handover target service (voice call service / text message service / data service, etc.). ) Using the terminal # 1 is moved to the terminal # 2 (S111). At this time, the user terminals (# 1, # 2) may determine the adjacent or separated from each other by measuring the power strength of the signals transmitted and received using the short-range wireless communication module (for example, Bluetooth, Zigbee, etc.), If two terminals (# 1, # 2) are placed within the coverage that is adjacent to each other within a predetermined distance (S112), the neighboring terminal service unit 220 according to the service request of the terminal # 1 that is using the service, the database as shown in FIG. If there is a terminal having a difference in priority among the plurality of terminals for the adjacent mode with reference to the information on the adjacent mode of 211, for example, service as a terminal adjacent to terminal # 1 (eg, terminal # 2). A terminal # 2 having a higher priority than the terminal performing the request may be controlled to perform a handover of the corresponding mobile communication service (S120 to S131).

For example, if UE # 1 is using a voice call service while being spaced apart from UE # 2, and wants to hand over it to UE # 2 when adjacent, UE # 1 is adjacent to UE # 2 as described above. UE # 1 that is using the service provider transmits a service request including subscriber identification information (eg, USIM information, etc.) to the customer management server 110 through the network (S120) and the adjacent terminal service unit of the customer management server 110. 220 receives this and first identifies the subscriber based on the corresponding subscriber identification information with reference to the database 211 (S121). Accordingly, the service usage priority of the plurality of terminals of the subscriber for the adjacent mode corresponding to the corresponding subscriber identification information, which exists in the database 211, is checked, and the terminal that is adjacent to the terminal # 1 (eg, the terminal # 2). As a terminal (eg, terminal # 2) having a higher priority than the terminal performing the service request, the terminal may control the mobile communication service to be handed over to the terminal # 2 (S122). In addition, when the terminal # 1 has the same priority as the terminal # 2, the neighbor terminal service unit 220 may control the two terminals to use the corresponding mobile communication service (see FIG. 7).

For example, in the case of a voice call service, as shown in FIG. 3, the terminal equipped with the USIM (A) may have a higher priority than the terminal equipped with the USIM (B). In addition, in the separation mode, the terminal equipped with the USIM (B) may have a higher priority than the terminal equipped with the USIM (A). In this case, the terminal that is powered off or does not communicate due to a failure may be processed according to the priority of the remaining terminals except the priority.

Accordingly, the service setting unit 240 may set the change history of the mobile communication service (for example, terminal information currently used by each subscriber) for the plurality of terminals of the subscriber. For example, referring to FIG. 3, the voice call service may be provided by the terminal equipped with the USIM (A) or the USIM (C) of the subscriber, unless there is a terminal that is powered off or does not communicate due to a failure. And, SMS service can be provided by the terminal equipped with the subscriber's USIM (A) or USIM (C), data (packet) service is provided by the terminal equipped with the subscriber's USIM (A) It can be provided. The service setting unit 240 may provide the change history upon request of equipment (eg, a switch, a home location register, etc.) on the mobile communication network to relay a service on the mobile communication network according to the corresponding change history information. .

When the change history of the mobile communication service is set as described above, the service setting unit 240 sends a text message indicating that the service has been released to the terminal # 1 in order to inform the transfer of the service in use from the terminal # 1 to the terminal # 2, and a push message. And the like (S130), and the terminal # 2 can be notified by a text message, a push message, etc. that the service has been transferred from the terminal # 1 has been started (S131).

Accordingly, the terminal # 2 can use the mobile communication service (voice / text / data, etc.) as its own subscriber identification information (eg, USIM information) (S140), and the subscriber identification information of the terminal # 1 (eg, USIM). Information), the mobile communication service (voice / text / data, etc.) can be used (S141). For example, the terminal # 2 may receive a mobile communication service (voice / text / data, etc.) that is received by the subscriber identification information of the terminal or the terminal # 1, and also selects the subscriber identification information of the terminal or the terminal # 1. It can also be used as a caller of a mobile communication service (voice / text / data, etc.). For this purpose, the notification message (text message, push message, etc.) transmitted to the terminal # 2 in step S131 may include subscriber identification information of the terminal # 1, and the terminal # 2 may set information as a source identifier of the mobile communication service. Can also be used as.

6 is a flowchart illustrating a handover process when terminals change from an adjacent state to a separated state.

First, in a state where the user terminals # 1 and # 2 are adjacent in the coverage of the adjacent mode (S210), for example, one or more of a handover target service (voice call service / text message service / data service, etc.). In step S211, the terminal # 1 moves away from the terminal # 2 in use. At this time, the user terminals (# 1, # 2) may determine the adjacent or separated from each other by measuring the power strength of the signals transmitted and received using the short-range wireless communication module (for example, Bluetooth, Zigbee, etc.), If the two terminals (# 1, # 2) outside the coverage not separated by a certain distance is not recognized (S212), the terminal service unit 220 in accordance with the service request of the terminal # 2 in use of the service as shown in FIG. If there is a terminal having a priority difference among the plurality of terminals in the separation mode with reference to the information on the separation mode of the database 211, for example, priority is higher than the terminal # 2 (eg, a service request performing terminal). It is possible to control the handover of the corresponding mobile communication service to the high terminal # 1 (the terminal being spaced apart from the terminal # 2) (S220 to S231).

For example, if UE # 2 is using the voice call service in the vicinity of UE # 1 and wants to hand over it to UE # 1 at a distance, if UE # 1 is spaced apart from UE # 2 as described above, the service is provided. The terminal # 2 that was in use transmits a service request including subscriber identification information (eg, USIM information) to the customer management server 110 through the network (S220), and the spaced terminal service unit of the customer management server 110 ( 230 receives this and first identifies the subscriber based on the corresponding subscriber identification information with reference to the database 211 (S221). Accordingly, the service usage priority of the plurality of terminals of the subscriber in the separation mode corresponding to the corresponding subscriber identification information, which exists in the database 211, is checked, and terminal # 2 (eg, a terminal performing a service request) among them. If a higher priority terminal (eg, terminal # 1) exists, it may be controlled to perform handover of the corresponding mobile communication service to terminal # 1 (S222). In addition, when the terminal # 1 has the same priority as the terminal # 2, the terminal service unit 230 may control both terminals to use the corresponding mobile communication service (see FIG. 7).

For example, in the case of a voice call service, as shown in FIG. 4, the terminal equipped with the USIM (A) may have a higher priority than the terminal equipped with the USIM (B). In addition, in the adjacent mode, the terminal equipped with the USIM (B) may have a higher priority than the terminal equipped with the USIM (A). In this case, the terminal that is powered off or does not communicate due to a failure may be processed according to the priority of the remaining terminals except the priority.

Accordingly, the service setting unit 240 may set the change history of the mobile communication service (for example, terminal information currently used by each subscriber) for the plurality of terminals of the subscriber. For example, referring to FIG. 4, the voice call service may be provided by a terminal equipped with the subscriber's USIM (A) unless the terminal is powered off or does not communicate due to a failure. (SMS) service can also be provided by the terminal equipped with the subscriber's USIM (A), data (packet) service can also be provided by the terminal equipped with the subscriber's USIM (A). The service setting unit 240 may provide the change history upon request of equipment (eg, a switch, a home location register, etc.) on the mobile communication network to relay a service on the mobile communication network according to the corresponding change history information. .

When the change history of the mobile communication service is set as described above, the service setting unit 240 sends a text message indicating that the service has been released to the terminal # 2 in order to notify that the service used in the terminal # 2 has been transferred to the terminal # 1, and a push message. And the like (S230), the terminal # 1 can be notified by the text message, push message, etc. that the service has been transferred from the terminal # 2 has been started (S231).

Accordingly, the terminal # 1 can use the mobile communication service (voice / text / data, etc.) as its subscriber identification information (eg, USIM information) (S240), and the subscriber identification information (eg, USIM) of the terminal # 2. Information), the mobile communication service (voice / text / data, etc.) can be used (S241). For example, the terminal # 1 may receive a mobile communication service (voice / text / data, etc.) that is received by the subscriber identification information of the terminal or the terminal # 2, and also selects the subscriber identification information of the terminal or the terminal # 2. It can also be used as a caller of a mobile communication service (voice / text / data, etc.). For this purpose, the notification message (text message, push message, etc.) transmitted to the terminal # 1 in step S231 may include subscriber identification information of the terminal # 2, and the terminal # 1 may set information as a source identifier of the mobile communication service. Can also be used as.

7 is a flowchart illustrating a handover process when simultaneously serving adjacent terminals.

First, in a state in which user terminals # 1 and # 2 are spaced apart from coverage of an adjacent mode (S310), for example, one or more of a handover target service (voice call service / text message service / data service, etc.). ) Using the terminal # 1 is moved to the terminal # 2 (S311). At this time, the user terminals (# 1, # 2) may determine the adjacent or separated from each other by measuring the power strength of the signals transmitted and received using the short-range wireless communication module (for example, Bluetooth, Zigbee, etc.), When the two terminals (# 1, # 2) are placed within the coverage that is adjacent to each other within a certain distance (S312), in response to the service request of the terminal # 1 in use of the service, the neighboring terminal service unit 220 may use the database (see FIG. 3). If there are terminals having the same priority among the plurality of terminals for the neighbor mode with reference to the information on the neighbor mode of 211, for example, a service request as a terminal neighboring to terminal # 1 (eg, terminal # 2). The terminal # 2 and the terminal # 2 having the same priority may be controlled to simultaneously perform the corresponding mobile communication service (S320 to S330).

For example, when UE # 1 is using a voice call service while it is spaced apart from UE # 2, and wants to handover such that the service is simultaneously performed between UE # 1 and UE # 2 when adjacent, UE # 1 is as described above. When the terminal # 2 is adjacent to the terminal # 2, the terminal # 1, which is using the service, transmits a service request including subscriber identification information (eg, USIM information) to the customer management server 110 through the network (S320). The neighbor terminal service unit 220 of the server 110 receives the first identification of the subscriber based on the corresponding subscriber identification information with reference to the database 211 (S321). Accordingly, the service usage priority of the plurality of terminals of the subscriber for the adjacent mode corresponding to the corresponding subscriber identification information, which exists in the database 211, is checked, and the terminal that is adjacent to the terminal # 1 (eg, the terminal # 2). If there is a terminal (eg, terminal # 2) having the same priority as the terminal performing the service request, the terminal # 1 and the terminal # 2 may be controlled to perform handover of the corresponding mobile communication service (S322). .

For example, in the case of a voice call service, as shown in FIG. 3, the terminal equipped with the USIM (A) may have the same priority as the terminal equipped with the USIM (C). In addition, in the separation mode, the terminal equipped with the USIM (B) may have a higher priority than the terminal equipped with the USIM (A) or the USIM (C) and thus may have received the corresponding service. In this case, the terminal that is powered off or does not communicate due to a failure may be processed according to the priority of the remaining terminals except the priority.

Accordingly, the service setting unit 240 may set the change history of the mobile communication service (for example, terminal information currently used by each subscriber) for the plurality of terminals of the subscriber. For example, referring to FIG. 3, the voice call service may be provided by the terminal equipped with the USIM (A) or the USIM (C) of the subscriber, unless there is a terminal that is powered off or does not communicate due to a failure. And, SMS service can be provided by the terminal equipped with the subscriber's USIM (A) or USIM (C), data (packet) service is provided by the terminal equipped with the subscriber's USIM (A) It can be provided. The service setting unit 240 may provide the change history upon request of equipment (eg, a switch, a home location register, etc.) on the mobile communication network to relay a service on the mobile communication network according to the corresponding change history information. .

When the change history of the mobile communication service is set as described above, the service setting unit 240 informs the terminal # 1 and the terminal # 2 that the service being used by the terminal # 1 is simultaneously serviced by the terminal # 1 and the terminal # 2. It can be informed that the corresponding service is made at the same time by a text message, a push message (S330).

Accordingly, the terminal # 1 and the terminal # 2 can use the mobile communication service (voice / text / data, etc.) as the subscriber identification information (for example, USIM information) at the same time. However, a service such as a text / data may be received or sent by the subscriber identification information from the terminal # 1 and the terminal # 2 like the general service (S340), and in the case of a voice call service, the terminal # 1 and the terminal # 2 All incoming calls can be made, but among them, the terminal that responds to the first call connection can receive the call with the other terminal. In the transmission of the voice call service, each terminal may make a call using its own subscriber identification information. However, in some cases, the terminal # 1 and the terminal # 2 may select subscriber identification information of the other terminal which serves itself or at the same time, and serve as a caller of the mobile communication service (voice / text / data, etc.). To this end, the notification message (text message, push message, etc.) transmitted to the terminal # 1 and the terminal # 2 in step S330 includes subscriber identification information of the corresponding terminal serving at the same time (for example, subscriber identification information of the terminal # 2 to the terminal # 1). Transmission), and each terminal may select one of two subscriber identification information and use it as information for setting as an originating identifier of a mobile communication service.
