Abstract

In a proximity service, when positional information is notifies to a server in advance and the proximity service is started, UE that transmits and receives data receives the proximity degree including a communication target UE from the server before proximity discovery is performed to discover the communication target UE, and the UE controls unnecessary proximity discovery by discovering the communication target UE based on the proximity degree.

1 . A Proximity Services (ProSe) Server comprising:
 transmitting and receiving circuitry configured to:
 receive, from a User Equipment (UE), location information of the UE, intermittently; 
 receive location information of another UE; and 
 transmit, to the UE, a first control information associated with a corresponding application ID among one or more application IDs; and 
   a controller configured to detect that the UE and the another UE are in proximity, wherein   the transmitting and receiving circuitry is configured for transmitting a plurality of control information respectively corresponding to each of the one or more application IDs in a procedure for detecting the another UE.   
     
     
         2 . The ProSe Server according to  claim 1 , wherein the first control information includes information for that the UE performs WLAN direct communication with the another UE. 
     
     
         3 . The ProSe Server according to  claim 1 , wherein the first control information includes identification information regarding the another UE. 
     
     
         4 . A communication control method performed by a Core Network, the communication control method comprising:
 receiving, from a User Equipment (UE), location information of the UE, intermittently;   receiving location information of another UE; and   transmitting, to the UE, a first control information associated with a corresponding application ID among one or more application IDs; and   detecting that the UE and the another UE are in proximity; wherein   the ProSe Server is configured for transmitting a plurality of control information respectively corresponding to each of the one or more application IDs in a procedure for detecting the another UE.   
     
     
         5 . The communication control method according to  claim 4 , wherein the first control information includes information for that the UE performs WLAN direct communication with the another UE. 
     
     
         6 . The communication control method according to  claim 4 , wherein the first control information includes identification information regarding the another UE.
