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 for explaining an inter-terminal handover support system 100 according to an embodiment of the present invention.

Referring to FIG. 1, an inter-terminal handover supporting system 100 according to an exemplary embodiment of the present invention may include a mobile communication service (e.g., a voice call, a text message SMS) through a mobile communication network operated by a mobile communication service provider, , A smart phone, a tablet PC, and a machine-to-machine (MTM) device, which are supported by a plurality of user terminals, and data (Internet, video call, LMS / If there is a mobile communication service commonly supported by these user terminals, the customer management server 110 recognizes a specific situation and provides a service handover between the terminals on the basis of the user without installing a modification of the user specific chip (USIM) Respectively. In service handover, the mobile communication service of the user A's terminal is performed only at the user B's terminal according to the neighboring state or the separation between the terminals, or the mobile communication service is performed only at the user A's terminal, Refers to a movement of a mobile communication service for allowing a terminal and a B terminal to simultaneously perform a service.

 The user terminal referred to in the present invention may be a mobile communication service (e.g., a mobile communication service) through a network (core network) in which networks according to protocols such as CDMA, WCDMA, WiFi, WiBro, (Smart phone) such as an iPod, an Android phone, and the like, as well as a cellular phone (cellular phone), a cellular phone (PCS) phone, a synchronous / asynchronous IMT-2000 (International Mobile Telecommunication-2000) capable of wireless communication, a personal digital assistant (PDA), a wap a mobile application such as a mobile phone, a wireless application protocol phone, a mobile game-station, or other portable multimedia player (PMP) A desktop PC, a palm personal computer (PC), and the like, and may include various electronic apparatuses or devices throughout the household or industrial society, such as a machine to machine (MTM) device capable of communicating with other electronic devices in some cases.

2, the client management server 110, which can be operated in the form of a server on the above-described network, supports the handover of the inter-terminal mobile communication service by the priority setting unit 210, A database 211 and a service control unit (a neighboring terminal service unit 220, a separation terminal service unit 230, and a service setting unit 240).

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

The priority setting unit 210 sets a service use priority order for a plurality of terminals for each subscriber in the database 211 according to an input by a user or an operator. Accordingly, the service control unit (the neighboring terminal service unit 220, the separated terminal service unit 230, and the service setting unit 240) determines whether a service request from any one of a plurality of terminals of the subscriber, And controls the handover of the mobile communication service so that the mobile communication service used by one of the plurality of terminals is used by the other terminal based on the service utilization priority order of the plurality of terminals of the corresponding subscriber.

As shown in FIG. 3 (in the adjacent mode) and FIG. 4 (in the separate mode), the service utilization priority for subscriber identification information (for example, USIM information) for distinguishing a plurality of terminals for each subscriber is stored in the database 211 And the service controller can identify the corresponding subscriber based on the subscriber identification information included in the service request from the terminal performing the service request (e.g., the terminal using the handover target service).

As described above, the database 211 stores a plurality of terminals (subscriber identification information) for each mobile communication service (e.g., voice communication service, text messaging service, or data service) The subscriber identification information may include USIM information (e.g., a terminal identification number (IMSI, MSISDN, etc.) of a Universal Subscriber Identification Module (USIM) installed in each terminal, a unique serial number , Country information, etc.), but the present invention is not limited thereto, and may be a telephone number, an IP (Internet Protocol) address, a MAC (Media Access Control) address, or the like.

Each terminal of the user can determine the proximity or separation of each other by mounting a short-range wireless communication module (e.g., Bluetooth, ZigBee, etc.), and any one of the terminals of the adjacent or spaced user can perform the service request In particular, such a service request can be performed by a terminal using a handover target service, that is, a terminal desiring to hand over a service to another terminal.

For example, in the database 211, a service use priority order of a plurality of terminals with respect to a subscriber-by-subscriber neighbor mode may be set as shown in FIG. 3, and the neighbor terminal service unit 220 may include a plurality of terminals (For example, a terminal that performs a service request as a neighboring terminal to a second terminal), if there is a difference in priority between the two terminals, 2 handover of the corresponding mobile communication service can be controlled. Here, if the first terminal has the same priority as the second terminal, the neighboring 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, a terminal equipped with a USIM (A) in an adjacent mode may have a higher priority than a terminal equipped with a USIM (B) as shown in FIG. In the ranging mode, a terminal equipped with a USIM (B) may have a higher priority than a terminal equipped with a USIM (A).

4, the service use priority order of a plurality of terminals for the subscriber-specific allocation mode may be set in the database 211, and the allocation terminal service unit 230 may allocate a plurality If there is a difference in priority between the two terminals which are spaced apart from each other and have a higher priority than the first terminal (e.g., a terminal performing a service request) 1 from the mobile station) to be handed over to the corresponding mobile communication service. Here, if the first terminal has the same priority as the second terminal, the detached terminal service unit 230 may control both terminals to use the corresponding mobile communication service. For example, in the case of a voice call service, a terminal equipped with a USIM (A) in a separation mode may have a higher priority than a terminal equipped with a USIM (B) as shown in FIG. In the adjacent mode, a terminal equipped with a USIM (B) may have a higher priority than a terminal equipped with a USIM (A).

Meanwhile, according to the handover control of the neighboring terminal service unit 220 and the separated terminal service unit 230 as described above, the service setting unit 240 sets a change history of the mobile communication service for a plurality of terminals of the subscriber (For example, an exchange, a home location register, etc.) on the mobile communication network so as to relate the service on the mobile communication network according to the change history, .

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 is a flowchart for explaining a handover process when the UEs are switched from the separated state to the adjacent state.

First, when the user terminals (# 1, # 2) are out of coverage in the adjacent mode (S110), for example, one or more of the handover target service (voice call service / text message service / The terminal # 1 in use moves to the terminal # 2 (S111). At this time, the user terminals # 1 and # 2 can determine the proximity or separation between the user terminals # 1 and # 2 by measuring the power intensity of signals transmitted and received using the installed short range wireless communication module (e.g., Bluetooth, ZigBee, etc.) When the two terminals (# 1, # 2) are located within a certain distance and are within mutually recognizable coverage (S112), the neighboring terminal service unit 220 receives the service request of the terminal # (For example, as a neighboring terminal to the terminal # 2), if there are terminals having a difference in priority among a plurality of terminals for the neighbor mode by referring to the information on the neighbor mode of the terminal # The handover of the corresponding mobile communication service can be controlled to the terminal # 2 having a higher priority than the terminal performing the request (S120 to S131).

For example, when the terminal # 1 is using the voice call service while the terminal # 1 is separated from the terminal # 2 and wants to hand over to the terminal # 2 when the terminal # 1 is adjacent to the terminal # The terminal # 1 that is using the terminal transmits the service request including the subscriber identification information (e.g., USIM information) to the customer management server 110 through the network (S120) The subscriber station 220 firstly refers to the database 211 and identifies the subscriber based on the subscriber identification information (S121). Accordingly, the service utilization priorities of the plurality of terminals of the subscriber in the neighbor mode corresponding to the corresponding subscriber identification information exist in the database 211, and the terminal # 1 (for example, The handover of the corresponding mobile communication service can be controlled to the terminal # 2 (S122) if a terminal having a higher priority (e.g., terminal # 2) exists than the terminal having the higher priority (e.g. Here, if the terminal # 1 has the same priority as that of the terminal # 2, the neighboring terminal service unit 220 may control both terminals to use the corresponding mobile communication service (refer to FIG. 7).

For example, in the case of a voice call service, a terminal equipped with a USIM (A) in an adjacent mode may have a higher priority than a terminal equipped with a USIM (B) as shown in FIG. Also, in the ranging mode, a terminal equipped with a USIM (B) may have a higher priority than a terminal equipped with a USIM (A). In this case, a terminal whose power is off or not communicating due to failure can be processed according to the priority order of the remaining terminals except for the priority order.

Accordingly, the service setting unit 240 can set a change history of the mobile communication service for a plurality of terminals of the corresponding subscriber (e.g., terminal information currently being used by each subscriber). For example, referring to FIG. 3, a voice call service can be provided by a terminal equipped with a USIM (A) or USIM (C) of a corresponding subscriber, unless there is a terminal whose power is off or communication is not failed (SMS) service can be provided by a terminal equipped with a USIM (A) or USIM (C) of the corresponding subscriber, and a data (packet) service can be provided by a terminal equipped with a subscriber's USIM . The service setting unit 240 can provide the change details upon request of equipment (e.g., an exchange, a home location register, etc.) on the mobile communication network so as to relay the service on the mobile communication network according to the corresponding change history information .

When the change history of the mobile communication service is set up, the service setting unit 240 notifies the terminal # 1 that the service being used by the terminal # 1 has been transferred to the terminal # 2, (S130). The terminal # 2 can notify that the service has been transferred from the terminal # 1 and started by a text message, a push message, or the like (S131).

Accordingly, the subscriber identification information of the subscriber terminal # 1 (e.g., USIM (voice / text / data), etc.) can be used as the subscriber identification information Information (voice / text / data, etc.) can be used (S141). For example, the terminal # 2 can receive the mobile communication service (voice / text / data, etc.) received by itself or the subscriber identification information of the terminal # 1, and can also select the subscriber identification information of itself or the terminal # And may be a sender of a mobile communication service (voice / text / data, etc.). For this, the subscriber identification information of the terminal # 1 may be included in the notification message (text message, push message, etc.) transmitted to the terminal # 2 in step S131, and the terminal # 2 may transmit the information .

6 is a flowchart for explaining a handover process when the UEs are switched from the adjacent state to the separated state.

First, when the user terminals # 1 and # 2 are adjacent to each other within the coverage of the adjacent mode (S210), for example, at least one of the handover target service (voice call service / text message service / The terminal # 1 moves away from the terminal # 2 in use (S211). At this time, the user terminals # 1 and # 2 can determine the proximity or separation between the user terminals # 1 and # 2 by measuring the power intensity of signals transmitted and received using the installed short range wireless communication module (e.g., Bluetooth, ZigBee, etc.) When the two terminals # 1 and # 2 are located apart from each other by a distance greater than a certain distance and can not recognize each other (S212), the neighboring terminal service unit 220, according to the service request of the terminal # For example, if there are terminals with a difference in priority among a plurality of terminals for the separation mode by referring to the information on the separation mode of the database 211, The handover of the corresponding mobile communication service can be controlled to be performed from the terminal # 1 (the terminal that is distant from the terminal # 2) (S220 to S231).

For example, when the terminal # 2 is using the voice call service while the terminal # 2 is adjacent to the terminal # 1 and desires to perform handover to the terminal # 1 when the terminal # 2 is located apart from the terminal # 1, The terminal # 2 that is being used transmits a service request including subscriber identification information (e.g., USIM information) to the customer management server 110 through the network at step S220, 230 identifies the subscriber based on the subscriber identification information with reference to the database 211 (S221). Accordingly, the service availability priority of the plurality of terminals of the subscriber in the allocation mode corresponding to the subscriber identification information exists in the database 211, and the terminal # 2 (e.g., the terminal performing the service request) If there is a terminal having a higher priority (e.g., terminal # 1), handover of the mobile communication service can be controlled to the terminal # 1 (S222). Here, if the terminal # 1 has the same priority as the terminal # 2, the detached terminal service unit 230 can control both terminals to use the corresponding mobile communication service (refer to FIG. 7).

For example, in the case of a voice call service, a terminal equipped with a USIM (A) in a separation mode may have a higher priority than a terminal equipped with a USIM (B) as shown in FIG. Also, in the adjacent mode, a terminal equipped with a USIM (B) may have a higher priority than a terminal equipped with a USIM (A). In this case, a terminal whose power is off or not communicating due to failure can be processed according to the priority order of the remaining terminals except for the priority order.

Accordingly, the service setting unit 240 can set a change history of the mobile communication service for a plurality of terminals of the corresponding subscriber (e.g., terminal information currently being used by each subscriber). For example, referring to FIG. 4, a voice call service can be provided by a terminal equipped with a USIM (A) of a corresponding subscriber, unless there is a terminal whose power is off or not communicated due to a failure, (SMS) service can also be provided by the terminal equipped with the USIM (A) of the subscriber, and the data (packet) service can be provided by the terminal equipped with the subscriber's USIM (A). The service setting unit 240 can provide the change details upon request of equipment (e.g., an exchange, a home location register, etc.) on the mobile communication network so as to relay the service on the mobile communication network according to the corresponding change history information .

When the change history of the mobile communication service is set, the service setting unit 240 notifies the terminal # 2 that the service being used by the terminal # 2 has been transferred to the terminal # 1, (S230). In step S231, the terminal # 1 can notify that the service has been transferred from the terminal # 2 and started by using a text message, a push message, or the like.

Accordingly, not only the subscriber identification information (e.g., USIM information) of the subscriber # 1 can use the mobile communication service (voice / text / data, etc.) Information (voice / text / data, etc.) can be used (S241). For example, the terminal # 1 can receive the mobile communication service (voice / text / data, etc.) received by itself or the subscriber identification information of the terminal # 2, and can also select the subscriber identification information of itself or the terminal # 2 And may be a sender of a mobile communication service (voice / text / data, etc.). For this purpose, the subscriber identification information of the subscriber station # 2 may be included in the notification message (text message, push message, etc.) transmitted to the subscriber station # 1 in step S231, and the subscriber identification information of the subscriber station # .

FIG. 7 is a flowchart for explaining a handover process when simultaneously serving neighboring terminals.

First, in a state where the user terminals # 1 and # 2 are out of coverage in the adjacent mode (S310), for example, at least one of the handover target service (voice call service / text message service / The terminal # 1 in use moves to the terminal # 2 (S311). At this time, the user terminals # 1 and # 2 can determine the proximity or separation between the user terminals # 1 and # 2 by measuring the power intensity of signals transmitted and received using the installed short range wireless communication module (e.g., Bluetooth, ZigBee, etc.) When the two terminals # 1 and # 2 are positioned within a predetermined distance and are within mutually recognizable coverage (S312), the neighboring terminal service unit 220 receives the service request of the terminal # If the UEs having the same priority among the plurality of UEs in the neighbor mode exist by referring to the information on the neighbor mode of the UE # 1 211 (for example, (S320 to S330) to simultaneously perform the mobile communication service in the terminal # 2 having the same priority as that of the terminal # 2.

For example, in a case where the terminal # 1 is using a voice call service while the terminal # 1 is separated from the terminal # 2 and wants to perform handover so that the neighboring terminals # 1 and # 2 can simultaneously perform the corresponding service, When the terminal # 1 is adjacent to the terminal # 2, the terminal # 1 that is using the service transmits a service request including the subscriber identification information (e.g., USIM information) to the customer management server 110 via the network (S320) The neighboring terminal service unit 220 of the server 110 receives the request and identifies the subscriber based on the subscriber identification information with reference to the database 211 (S321). Accordingly, the service utilization priorities of the plurality of terminals of the subscriber in the neighbor mode corresponding to the corresponding subscriber identification information exist in the database 211, and the terminal # 1 (for example, The handover of the corresponding mobile communication service can be controlled to the terminal # 1 and the terminal # 2 (S322) if there is a terminal having the same priority (for example, terminal # 2) .

For example, in the case of a voice call service, a UE equipped with a USIM (A) in an adjacent mode may have the same priority as a UE equipped with a USIM (C) as shown in FIG. Also, in the separation mode, a terminal equipped with a USIM (B) may have a higher priority than a terminal equipped with a USIM (A) or USIM (C), and may receive the corresponding service. In this case, a terminal whose power is off or not communicating due to failure can be processed according to the priority order of the remaining terminals except for the priority order.

Accordingly, the service setting unit 240 can set a change history of the mobile communication service for a plurality of terminals of the corresponding subscriber (e.g., terminal information currently being used by each subscriber). For example, referring to FIG. 3, a voice call service can be provided by a terminal equipped with a USIM (A) or USIM (C) of a corresponding subscriber, unless there is a terminal whose power is off or communication is not failed (SMS) service can be provided by a terminal equipped with a USIM (A) or USIM (C) of the corresponding subscriber, and a data (packet) service can be provided by a terminal equipped with a subscriber's USIM . The service setting unit 240 can provide the change details upon request of equipment (e.g., an exchange, a home location register, etc.) on the mobile communication network so as to relay the service on the mobile communication network according to the corresponding change history information .

When the change details of the mobile communication service are set as described above, the service setting unit 240 sets the change history of the mobile communication service to the terminal # 1 and the terminal # 2 in order to notify that the service being used by the terminal # The service can be notified at the same time by a text message, a push message, or the like (S330).

Accordingly, the terminal # 1 and the terminal # 2 can simultaneously use the mobile communication service (voice / text / data, etc.) with their respective subscriber identification information (e.g., USIM information). However, services such as text / data can be received or originated by the respective subscriber identification information in the terminal # 1 and the terminal # 2 (S340) like a general service, and in the case of the voice call service, However, it is possible to make a call with the other party terminal by receiving a terminal that responded first by a call connection among them. In the origination of the voice call service, each terminal can transmit the call using its own subscriber identification information. However, in some cases, the terminal # 1 and the terminal # 2 can select the subscriber identification information of the terminal itself or another terminal simultaneously serving as a sender of the mobile communication service (voice / text / data, etc.). For this, in step S330, the subscriber identification information (e.g., subscriber identification information of the subscriber identification information of the subscriber terminal # 2 to the subscriber terminal # 1) Transmission) may be included. Accordingly, each of the terminals may use any of the two subscriber identification information as information for setting the transmission identifier of the mobile communication service.

While the invention has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. This is possible. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined by the equivalents of the claims, as well as the claims.
