Relay method of transport bearer, apparatus and communication system

摘要

Embodiments of the present invention disclose a relay method of a transport bearer, an apparatus and a communication system. According to the technical solutions in the present invention, when receiving information encapsulated by a source device and sent by the source device, a relay base station first decapsulates the information, encapsulates the information again, and then sends the encapsulated information to a host device, thus ensuring that the information has only a layer of encapsulation in the transport procedure, so as to avoid a case that a high overhead caused by two layers of encapsulation occurs in the transport procedure. Compared with the prior art, the overhead in the transport procedure may be reduced, and the transport efficiency may be increased.

1. A relay method of a transport bearer, comprising:
receiving information encapsulated by a source device and sent by the source device; decapsulating the received information encapsulated by the source device; encapsulating the decapsulated information; and sending the encapsulated information to a host device; wherein the receiving the information encapsulated by the source device and sent by the source device comprises: receiving a signaling message or data, wherein the signaling message or data is encapsulated by the source device and sent by the source device; the decapsulating the received information encapsulated by the source device comprises: parsing the received signaling message or data, wherein the received signaling message or data is encapsulated by the source device; the encapsulating the decapsulated information comprises: performing signaling bearer address replacement on the parsed signaling message, or performing data bearer address replacement on the parsed data; and the sending the encapsulated information to the host device comprises: sending the signaling message after the signaling bearer address replacement to the host device, or sending the data after the data bearer address replacement to the host device.
