Abstract

The invention discloses a base station configuration and cell selection / switching method, device and system and associated equipment so as to prevent frequent cell selection / switching operation in the UE moving process, which may influence the service life of a battery or network performance. The base station configuration method comprises the following steps: judging whether a picocell covered by a pico-base station meets a preset cell coverage condition, wherein the preset cell coverage condition comprises that the picocell is fully covered by a macrocell covered by a deployed macro base station, or the picocell is fully covered by at least one PBCH unshielded picocells covered by other pico-base stations; and if so, configuring the physical broadcast channel (PBCH) of the pico-base station to be in a PBCH shielding state.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a base station configuration and cell selection / handover method, device, system and related equipment. Background technique [0002] An LTE-A (Long Time Evolution Advanced, enhanced long-term evolution) network cellular system generally implements heterogeneous deployment of a set of enhanced base stations (eNBs) to reduce cell scale and improve spectrum efficiency. To improve coverage and user equipment (UE) throughput in heterogeneous networks, macro eNBs can be deployed with high transmit power and pico eNBs within the coverage area can be deployed with relatively low transmit power. This overlapping coverage deployment can increase capacity gains by enhancing space division multiplexing of spectrum. [0003] After the user equipment (UE) within the coverage area of ​​the LTE-A network is powered on, the UE first performs a cell selection process, and thr...
