A network switching method and device

Abstract

Embodiments of the present invention provide a network handover method and device, the method comprising: receiving first measurement report information sent by a user terminal, where the first measurement report information includes a first handover target cell and a user terminal identifier; if according to the user terminal Identifying and judging that the user terminal is a carrier aggregation user, obtaining the priority of each wireless network cell in the carrier aggregation group corresponding to the first handover target cell; For the wireless network cell, the wireless network cell with the highest priority in the carrier aggregation group is selected as the second handover target cell, and the second handover target cell is handed over as the serving cell of the user terminal according to preset rules. The device is used to perform the above method. The embodiment of the present invention avoids handover of the user terminal to a wireless network cell with a small coverage area, resulting in frequent and chaotic handover, and improves the performance of the wireless communication network.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of wireless networks, and in particular to a network switching method and device. Background technique [0002] 3GPP (3rd Generation Partnership Project, third-generation mobile communication partnership organization) introduced carrier aggregation (Carrier Aggregation, hereinafter referred to as CA) in the Release 10 phase, by combining multiple continuous or discontinuous subcarriers (Component Carrier, referred to as CC) Aggregate into a larger bandwidth to meet 3GPP's requirements for speed. To implement CA, subcarriers need to be configured on the side of the eNodeB (Evolved Node B, evolved Node B, the name of the base station in the LTE network). When the UE, that is, the user terminal, meets the relevant level conditions, the eNodeB will configure multiple subcarriers. In general scenarios, the subcarriers included in the same sector are configured in the same group, and dif...

Problems solved by technology

However, when performing network switching in the prior art, the coverage of sub-carriers is not considered, but the switching is performed according to the signal strength, and the coverage of sub-carriers has no substantial relationship with the signal strength.

If for some reason, sub-carriers with smaller coverage are configured as PCells, problems such as frequent and confusing handovers, interoperability between systems caused by coverage holes, and call drops caused by handovers caused by corner effects will easily occur, which will degrade network performance.
