METHOD AND USER EQUIPMENT FOR IMPLEMENTING DEVICE TO DEVICE COMMUNICATIONS BETWEEN UES

摘要

The present application provides a method for implementing a device to device (D2D) START communication between UEs, wherein a UE and a network obtain each other's capability of Proximity Service (ProSe); the UE may activate the capability of ProSe that both the UE and the network support and initiates a request for a ProSe service with another UE to the network; the network authenticates the request for the ProSe service according to subscription information for the UE's device to device communication; and the network establishes a device to device PDN bearer between the two UEs for the request for the ProSe service passing the authentication. The present application further provides a user equipment. The present application is the basis for implementing the ProSe, the application thereof can satisfy service demands of public safety communication and realize network resource optimization configuration.
