Embodiment 1

[0043] This embodiment will be described from the perspective of a relay base station.

[0044] A relay method for transmission bearer, comprising: receiving information encapsulated by the source device sent by the source device, decapsulating the information encapsulated by the source device, encapsulating the decapsulated information, and encapsulating the encapsulated information The information is sent to the sink device. like figure 1 As shown, the specific process can be as follows:

[0045] 101. Receive the information encapsulated by the source device sent by the source device;

[0046] Wherein, the received information can be uplink information or downlink information, that is, the source device can be a self-backhaul base station, correspondingly, the sink device can be a gateway; or the source device can be a gateway, correspondingly, the sink The device can be a self-backhaul base station; in addition, the information can be a signaling message or data, and the...

Embodiment 2

[0085] According to the method described in Embodiment 1, the embodiment of the present invention will be further described in detail by taking a Long Term Evolution (LTE, Long Term Evolution) system as an example.

[0086] The schematic diagram of the LTE system can be found in figure 2 , where the long-term evolution base station (eNB, E-UTRAN Node B, hereinafter referred to as the evolved base station) is the relay base station, the mobility management network element (MME, Mobility Management Entity) is the gateway corresponding to the signaling message transmission, and the serving gateway ( S-GW, Serving-Gateway) is a gateway corresponding to data transmission. A terminal (UE, User Equipment, user terminal equipment, terminal for short) interacts with a self-backhaul base station through a wireless air interface bearer. First of all, it is necessary to add a transmission bearer relay function in the evolved base station, which can be referred to as the "S1Relay" functi...

Embodiment 3

[0111] In the second embodiment, the interaction of the signaling message "S1 Setup" is described as an example. Since the interaction of the signaling message has nothing to do with the terminal, in order to better describe the embodiment of the present invention, this embodiment will be described as follows A detailed description is given by taking a terminal-related signaling interaction as an example.

[0112] In the signaling interaction process related to the terminal, in order to identify different terminals, it is necessary to generate a pair of signaling identifiers and carry the pair of signaling identifiers in the interaction process of signaling messages. For the convenience of description, the pair of signaling identifiers are named as eNB UE S1AP ID and MME UE S1AP ID in the embodiment of the present invention. For the convenience of description, in the following embodiments, the Add different subscripts to different pairs of signaling identities. For example, if...

Abstract

The embodiment of the invention discloses a transmission bearing relaying method, a device and a communication system. According to the technical scheme of the invention, when a relaying base station receives information which is sent and encapsulated by source end equipment, the relaying base station de-encapsulates the information first, then re-encapsulates the information and sends the information to terminal end equipment so as to ensure that the information has only one layer of encapsulation during the transmission and the condition of great expense due to two layers of encapsulation during the transmission is avoided. Compared with the prior art, the expense during the transmission can be reduced, and the transmission efficiency can be improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a relay method, device and communication system for transmission bearer. Background technique [0002] In a wireless communication system, in order to ensure the normal transmission and reception of user data, it is generally necessary to establish a wireless air interface bearer between the user terminal and the base station, and establish a transmission bearer between the base station and the gateway; at the same time, the wireless air interface bearer of the terminal and the transmission bearer from the base station to the gateway It is a one-to-one correspondence, for example, there is a one-to-one correspondence between a wireless air interface bearer ID (ID, Identity) and a transmission bearer ID. [0003] If during the data transmission process, the base station that establishes wireless air interface bearer with the terminal is a self-backhaul base station ...
