Abstract

The present invention relates to a wireless communication system. More particularly, disclosed are a network-initiated control method and an apparatus for providing a proximity service (ProSe). A method for supporting ProSe between a plurality of terminals at a network node of a wireless communication system according to one embodiment of the present invention comprises: a step of acquiring base ProSe information from one or more of the plurality of terminals or from one or more of other network nodes; a step of allowing the network node to detect whether ProSe is enabled between the plurality of terminals based on the acquired base ProSe information; and a step of transmitting information indicating whether ProSe is allowed or not to one or more of the plurality of terminals.

First claim

1 . A method of a network node supporting proximity service (ProSe) between at least a first user equipment (UE) and a second UE in a wireless communication system, the method comprising:
receiving ProSe capability information and subscriber information; determining whether the first UE is authorized to use the ProSe based on the subscriber information; and transmitting ProSe permissibility indication information that includes information related to authentication of the first UE to use the ProSe when the first UE is authorized to use the ProSe based on the determination and the ProSe capability information indicates the first UE is enabled for the ProSe.

2 . The method according to claim 1 , wherein the ProSe capability information is received from the first UE.

3 . The method according to claim 1 , further comprising storing the received subscriber information.

4 . The method according to claim 1 , further comprising receiving ProSe information that includes at least location information, ProSe capability enable state information, preference information, device identification information, user identification information, group identification information, a list of opposite UEs, ProSe relationship information of each of the at least first and second UE with regard to the opposite UEs, operator policy information, network ProSe capability information or network congestion information related to each of the at least first and second UE.

5 . The method according to claim 1 , wherein the ProSe permissibility indication information is configured as indication information that indicates at least whether ProSe is enabled between the at least first and second UE, whether to perform direct communication between the at least the first and second UE or whether to set up a direct data path between the at least first and second UE.

6 . The method according to claim 5 , wherein the ProSe permissibility indication information further includes information indicating at least whether ProSe is enabled, information related to a use level of ProSe, information related to an opposite UE for ProSe, information related to a media type, a content type, an application type, or a service type for ProSe, information related to directivity for ProSe, information related to an amount of data for ProSe or information about an access type for ProSe.

7 . The method according to claim 6 , wherein the ProSe permissibility indication information further includes information related to at least Quality of Service (QoS), policy control rules or charging control rules.

8 . The method according to claim 7 , wherein the ProSe permissibility indication information further includes at least ProSe identification information, direct communication identification information or direct data communication path identification information.

9 . The method according to claim 8 , wherein the ProSe identification information, the direct communication identification information, and the direct data communication path identification are defined with at least one granularity among a media or content type, an Access Point Name (APN), a QoS Class Identifier (QCI), a bearer or connection type, an application type, a service type, a destination domain, an opposite UE for communication, predefined user group information, predefined subscriber group information, predefined UE group information, or a Closed Subscriber Group (CSG).

10 . The method according to claim 1 , further comprising initiating direct data path setup between the at least the first and second UE upon receiving a direct data path setup request from at least the first or second UE.

11 . The method according to claim 1 , further comprising initiating direct data path setup between the at least the first and second UE without receiving a direct data path setup request from at least the first or second UE.

12 . The method according to claim 1 , wherein:
the ProSe capability information includes at least location information of the at least first and second UE, ProSe capability information of the at least first and second UE or ProSe capability enabled state information of the at least first and second UE; the ProSe capability information of the at least first and second UE indicates whether the at least first and second UE have ProSe capability; and the ProSe capability enabled state information of the at least first and second UE indicates whether the ProSe of the first UE and the second UE is enabled or disabled.

13 . The method according to claim 1 , further comprising receiving ProSe performance result information that includes at least direct communication identification information, direct data communication path identification information, information indicating success or failure of setup of a direct data path, information related to an amount of data for communication through the direct data path, information related to time for which the direct data path is maintained, information related to a type of media or contents communicated through the direct data path, information related to directivity of the direct data path, information related to an access type used for the direct data path or information related to a number and types of bearers used for the direct data path.

14 . The method according to claim 1 , wherein the network node comprises at least a Mobility Management Entity (MME), a Serving GPRS (General Packet Radio Service) Supporting Node (SGSN), an evolved Node B (eNodeB) or a ProSe server.

15 . A network node for supporting proximity service (ProSe) between at least a first user equipment (UE) and a second UE in a wireless communication system, the network node comprising:
a transceiver module for transmitting and receiving signals between the network node and an external device; and a processor configured to: control the transceiver module to receive ProSe capability information and subscriber information; determine whether the first UE is authorized to use the ProSe based on the subscriber information; and control the transceiver to transmit ProSe permissibility indication information that includes information related to authentication of the first UE to use the ProSe when the first UE is authorized to use the ProSe based on the determination and the ProSe capability information indicates the first UE is enabled for the ProSe.

16 . The network node according to claim 15 , wherein the processor is further configured to store the received subscriber information.

17 . The network node according to claim 15 , wherein the processor is further configured to control the transceiver module to receive ProSe information that includes at least location information, ProSe capability enable state information, preference information, device identification information, user identification information, group identification information, a list of opposite UEs, ProSe relationship information of each of the at least first and second UE with regard to the opposite UEs, operator policy information, network ProSe capability information or network congestion information related to each of the at least first and second UE.

18 . The network node according to claim 15 , wherein the ProSe permissibility indication information is configured as indication information that indicates at least whether ProSe is enabled between the at least first and second UE, whether to perform direct communication between the at least the first and second UE or whether to set up a direct data path between the at least first and second UE.
