Embodiment Construction

[0031] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0032] method embodiment

[0033] According to an embodiment of the present invention, a method for identifying a relay node is provided, figure 2 It is a flow chart of Embodiment 1 of the relay node identification method according to the present invention.

[0034] Such as figure 2 As shown, this embodiment includes:

[0035] Step S102: the relay node carries a specific relay node identifier in the non-access sublayer message;

[0036] Step S104: The network side identifies the connected user-side device according to the relay node identifier, and determines whether it is a relay node.

[0037] In this embodiment, the relay node carries a specific relay node ...

Abstract

The invention discloses a method for identifying a relay node, a base station, the relay node and a mobile management entity (MME). The method comprises the following steps that: the relay node carries a specific relay node identifier in a non-access sublayer message; and a network side identifies the relay node according to the relay node identifier. Through each embodiment of the invention, the relay node can access network identification and complete the functions of verification of the relay node and the like at the same, and the defect that the relay node cannot be identified in an LTE-A network in the conventional access mode is overcome.

Description

technical field [0001] The present invention relates to the relay technology in the communication field, in particular to a relay node identification method, a base station, a relay node and a mobility management entity. Background technique [0002] figure 1 A schematic flow chart of performing network-side attach (Attach) for an existing user equipment (User Equipment, UE for short). Such as figure 1 As shown, in the existing LTE network, after the user side UE completes the connection establishment request (RRCConnectionRequest) through the uplink random access procedure (RACH), the base station side will feed back the connection establishment (RRCConnectionSetup) message, as shown in figure 1 In the evolved Node B (Evolved Node B, referred to as eNB), the user side sends a connection establishment complete (RRCConnectionComplete) message to the base station side. By forwarding the initial UE message (that is, the Initial UE Message) to the mobility management entity (...
