Description

Background technique

In the existing LTE system, the user in the connected state changes the channel quality under the connected cell, affects the service rate, and protects the user service during the mobile process, or due to network coverage or network load. Quality, the UE searches for the neighboring neighboring area, and reports the neighboring cell that is searched and meets the measurement requirements to the base station and wants the base station to switch it. In the base station processing, when the neighboring cell does not have a neighboring cell relationship with the serving cell. If the handover fails, the next UE needs to report the measurement information of other neighboring areas.

When a base station is placed in an existing network, the neighboring relationship needs to be manually added by the network planner. This requires not only a large amount of human and material resources, but also mismatching and mismatching due to environmental changes and human negligence.
