Problems solved by technology

This short-term handover increases the interaction burden between the base station and the core network, but the throughput benefit is not obvious
Especially in the scenario of continuously passing through several small base stations, this continuous switching brings system burden

Abstract

Embodiments of the present invention provide a cell switching method, base station equipment and user equipment. The method includes: determining the cell switching type of the user equipment according to the measurement report sent by the user equipment and / or the moving speed of the user equipment; determining the cell switching type When the partial handover type is used, a partial handover request is sent to the target base station. The partial handover request is used to request the target base station to configure the PDCCH that the user equipment monitors. Embodiments of the present invention can perform partial handover of the user equipment's services, and the target base station configures the PDCCH that the user equipment monitors, instead of switching all the user equipment's services to the target base station, thereby reducing the interaction burden during handover.

Description

Technical field [0001] The embodiments of the present invention relate to the field of communication technology, and more specifically, to a cell handover method, base station equipment, and user equipment. Background technique [0002] Heterogeneous networks can improve the coverage and capacity of mobile networks. Take the LTE (Long Term Evolution) heterogeneous network as an example. Place small base stations, such as Pico (micro base station), HeNB (Home eNB, home base station), Femto (pico base station), within the coverage of Macro eNB (macro base station). ), Relay (relay base station) and other wireless access points. UE (User Equipment) is under the dual coverage of macro base stations and small base stations. All base stations can be deployed at the same frequency or at different frequencies. The maximum capacity that a heterogeneous network system can obtain is the sum of the capacities of the macro base station and the small base station, and the entire communicati...
