Secure group creation in proximity based service communication

Abstract

A method of forming a secure group in ProSe communication includes requesting a service request to a ProSe server from a requesting device ( 21 ), the service request indicating a request to communicate with a receiving device ( 22 ) from the requesting device ( 21 ), performing verification on the requesting and receiving devices ( 21 ) and ( 22 ) by the ProSe server 24 , sending a ProSe Service Result to the requesting and receiving devices ( 21 ) and ( 22 ) to inform to be allowed a group member, and starting a group security establishment of the group including the requesting and receiving devices ( 21 ) and ( 22 )

1 . A first server for group management in a mobile communication system, the first server comprising:
 a processor; and   a memory having stored thereon a set of instructions executable by the processor, wherein, upon execution of the set of instructions, the processor causes the first server to:
 receive, from a first user equipment (UE), a request message including a first identification (ID) of the first UE, a list of second IDs of a plurality of second UEs, and first information about a request service, 
 perform verification of one or more of the plurality of second UEs, 
 send a verification result and a group ID of a group of UEs to the first UE, and 
 send the group ID to the one or more of the plurality of second UEs. 
   
     
     
         2 . The first server according to  claim 1 , wherein the request message includes second information about a request communication. 
     
     
         3 . The first server according to  claim 1 , wherein the first server sends third information about the first UE and the plurality of second UEs to a second server. 
     
     
         4 . The first server according to  claim 1 , wherein the request message is used to create the group of UEs. 
     
     
         5 . A method of a first server for group management in a mobile communication system, the method comprising:
 receiving, from a first user equipment (UE), a request message including a first identification (ID) of the first UE, a list of second IDs of a plurality of second UEs, and first information about a request service;   performing verification of one or more of the plurality of second UEs;   sending a verification result and a group ID of a group of UEs to the first UE; and   sending the group ID to the one or more of the plurality of second UEs.   
     
     
         6 . The method according to  claim 5 , wherein the request message includes second information about a request communication. 
     
     
         7 . The method according to  claim 5 , wherein the first server sends third information about the first UE and the plurality of second UEs to a second server. 
     
     
         8 . The method according to  claim 5 , wherein the request message is used to create the group of UEs. 
     
     
         9 . A first user equipment (UE) in a mobile communication system including a first server for group management, the first UE comprising:
 a processor; and   a memory having stored thereon a set of instructions executable by the processor, wherein upon execution of the instructions the processor causes the first UE to:
 send, to the first server, a request message including a first identification (ID) of the first UE, a list of second IDs of a plurality of second UEs, and first information about a request service, and 
 receive a verification result and a group ID of a group of UEs from the first server,
 wherein one or more of the plurality of second UEs receive the group ID from the first server. 
 
   
     
     
         10 . The first UE according to  claim 9 , wherein the request message includes second information about a request communication. 
     
     
         11 . The first UE according to  claim 9 , wherein the first server sends third information about the first UE and the plurality of second UEs to a second server. 
     
     
         12 . The first UE according to  claim 9 , wherein the request message is used to create the group of UEs. 
     
     
         13 . A method of a first user equipment (UE) in a mobile communication system including a first server for group management, the method comprising:
 sending, to the first server, a request message including a first identification (ID) of the first UE, a list of second IDs of a plurality of second UEs, and first information about a request service; and   receiving a verification result and a group ID of a group of UEs from the first server,
 wherein one or more of the plurality of second UEs receive the group ID from the first server. 
   
     
     
         14 . The method according to  claim 13 , wherein the request message includes second information about a request communication. 
     
     
         15 . The method according to  claim 13 , wherein the first server sends third information about the first UE and the plurality of second UEs to a second server. 
     
     
         16 . The method according to  claim 13 , wherein the request message is used to create the group of UEs.
