Embodiment Construction

[0054] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and examples.

[0055] figure 2 It is a schematic flowchart of a method for implementing end-to-end communication between UEs in this application, and the method includes the following steps:

[0056] Step 201: the UE and the network obtain the communication capability of the other party's Proximity-based Services (Proximity-based Services, ProSe).

[0057] The UE and the network need to obtain each other's ProSe communication capabilities.

[0058] The UE's ProSe communication capability includes: UE ProSe wireless capability and UE ProSe core network capability;

[0059] The ProSe communication capability of the network includes: EPS ProSe network capability support and EUTRAN ProSe network capability support.

[0060] The UE ProSe core network capability i...

Abstract

The present application provides a method for implementing a device to device (D2D) 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.

Description

technical field [0001] The present application relates to wireless communication technologies, and in particular to a method for implementing end-to-end communication between UEs and user equipment. Background technique [0002] Modern mobile communication tends to provide diversified services to users, such as figure 1 Shown is the system architecture diagram of the existing Evolved Packet System (EPS). exist figure 1 Among them, a user equipment (UE) 101 is a terminal device for receiving data. Evolved Universal Terrestrial Radio Access Network (E-UTRAN) 102 is a radio access network that includes macro base stations (eNodeBs) that provide UEs with an interface to access the radio network. Mobility Management Entity (MME) 103 is responsible for managing UE's mobility context, session context and security information. Serving Gateway (SGW) 104 mainly provides user plane functions, and MME 103 and SGW 104 may be in the same physical entity. The packet data network gatew...
