Abstract

The invention provides a switching method and device. The method includes the following steps: when a serving base station of user equipment (UE) switches from a source base station to a target base station, the source base station sends a switching request message to the target base station, wherein the switching request message carries data radio bearer (DRB) information of one or more UE at thesource base station and flow-level quality of service (Flow QoS) information of one or more UE at the core network side; the source base station receives a switching request confirmation message sentby the target base station, wherein the switching request confirmation message carries DRB configuration information of the UE at the target base station; and the source base station sends an RRC connection reconfiguration message carrying the DRB configuration information of the UE at the target base station to the UE. According to the scheme of the invention, the problem that QoS mechanisms adopted by a core network and an access network cannot be unified during base station switching in related technologies can be solved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a handover method and device. Background technique [0002] In 4G (4Generation, fourth generation) or LTE (Long Term Evolution, long-term evolution) mobile communication system, figure 1 It is a schematic diagram of a 4G system in the related art of the present invention, which aggregates data streams with the same QoS (Quality of Service) requirements into a bearer, and the access network (Access Network, AN) and the core network (CoreNetwork, CN) have a corresponding QoS The processing is carried out according to the bearer. In a 4G system, an access network includes an evolved base station (evolvedNode B, eNB) and a user equipment (User Equipment, UE). The network-side bearer on the S1 interface between the eNB and the core network and the radio bearer on the air interface between the eNB and the UE correspond 1:1. [0003] In the 4G system, QoS parameters include: QCI (Qo...
