Update method of radio bearer and relay station

Abstract

The embodiment of the invention discloses an updating method of a radio bearer and a relay station, relating to the technical field of communications and being used for improving the use ratio of air-interface resources. The method comprises the following steps: acquiring a first bearing message of user equipment (UE), wherein the first bearing message refers to the service quality of the radio bearer to be switched of the UE; when the service quality of radio bearing resources on a Un interface does not meet the switching requirements of the bearer of the UE, determining the requirements of the UE on the service quality of the radio bearing resources on the U interface in accordance with the first bearing message; and sending a bearing resource modification request to a core network, wherein the request carries the requirements of the UE on the service quality of the radio bearing resources on the Un interface, so that a donor base station can update the radio bearer on the Un interface in accordance with the requirements of the service quality. The updating method and the relay station in the embodiment of the invention are mainly applied to occasions in which relays exist.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to a radio bearer update method and a relay station. Background technique [0002] In order to improve the quality of wireless signal coverage in hotspot areas at the edge of the cell, the wireless relay (Relay) technology is introduced into the advanced Long Term Evolved-Advanced (LTE-A) system, and the corresponding relay equipment is called a relay A relay node (Relay Node, RN) or a relay station (RelayStation, RS). The relay station communicates with the base station through the air interface, and is responsible for one or more signal processing or direct forwarding of the wireless signal sent by the base station until the wireless signal is sent to the user equipment (User Equipment, UE). After introducing the relay technology, the base station may be called a donor base station (DonorE-UTRAN Node B, DeNB). Wherein, the interface between the relay station an...

Problems solved by technology

[0004] In the process of implementing the present invention, the inventors found that in the handover process, there is no solution for updating the QoS (Quality of Service) of radio bearer resources on the Un interface in the prior art, so that The radio bearer resources do not match the radio bearer resources required in the handover process, resulting in waste of radio bearer resources on the Un interface or loss of forwarded data, reducing the utilization of air interface resources
