Abstract

The invention discloses a method and a system for base station handover. The method comprises the following steps that: user equipment is handed over to a target base station from a source base station; the packet data convergence protocol layer of the target base station judges whether the signalling radio bearer of the user equipment receives a first uplink message, if so, then the user equipment is determined to be successfully accessed to the target base station; the target base station carries out uplink and downlink data transmission with the user equipment. According to the scheme, whether UE is successfully accessed can be judged in time in a mode of judging whether UE is successfully accessed through switching the first uplink message received by the uplink of the SRB of the UE on the physical layer of a PDCP; meanwhile, because the judgement is realized in the PDCP, signalling interaction between the PDCP and RRC is reduced; therefore, the timeliness of the data sent to the UE by TeNB during handover can be improved, handover time delay can be reduced, and user experience can be improved.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a base station switching method and system. Background technique [0002] The overall development trend of the mobile Internet will be the mutual integration with the Internet. At the business level, the content and application experience of the mobile Internet and the traditional Internet tend to be consistent. However, the launch of mobile network products is faster than that of the traditional Internet. At the network service level, Compared with the fixed Internet, cheap and relatively fast Internet access mode has also begun to be provided. [0003] For example, LTE (Long Term Evolution) is a wireless communication standard specially designed for mobile high-bandwidth applications. Higher bandwidth, larger capacity, and higher The effect of data transfer rate and lower transmission delay. [0004] LTE uses a fast hard handover method to realize handov...
