Abstract

Embodiments of the present invention provides a method and apparatus for providing relay services, receiving a second message transmitted by the MME via P-GW, wherein the second message comprises a first identifier of the remote UE, according to the first identification of the remote UE to determine the upstream packet filter of the remote UE, to determine the upstream TFT of the relay UE, the upstream TFT contains the upstream packet filter of the remote UE, Wherein the upstream packet filter of the remote UE is used to relay the upstream packet of the remote UE to the EPS bearer of the relay UE, thus ensuring that the IP address used by the remote UE through the relay UE access network is consistent with the IP address used by the remote UE in the cell coverage area access network, thereby ensuring the continuity of data transmission.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a method and device for providing a relay service. Background technique [0002] In wireless communication, in order to improve data transmission efficiency, Proximity Services (full name in English: ProximityServices, hereinafter referred to as: ProSe) technology is used to enable user equipment (User Equipment, hereinafter referred to as UE) outside the coverage area of ​​the cell to pass The UE communicates with the base station, thereby improving data transmission efficiency. [0003] For ease of description, the UE outside the coverage of the cell is called a remote UE (English: remote UE), and the UE within the coverage of the cell is called a relay UE (English: relay UE). In the prior art, the remote UE Utilize the discovery process in the ProSe technology to determine the relay UE, and establish a connection and communication with the relay UE, and ...
