Abstract

Embodiments of the present invention provide a handover method and device suitable for multi-connection networks, which are applied to LTE base stations. The method includes: obtaining the measurement result of the received signal strength of the surrounding millimeter-wave access points measured by the user equipment, and calculating the user equipment The device receives the signal-to-interference-noise ratio value of the signal, and adds the millimeter-wave access points in the inactive set that meet the preset conditions to the candidate set, and then judges whether the signal-to-interference-noise ratio value is lower than the set threshold value and whether the candidate set is If it is not empty, trigger handover, use the recursive least squares method to predict the signal strength of the millimeter wave access point, and make the user equipment switch to the preset number of millimeter wave access points with the highest predicted signal strength. By applying the embodiment of the present invention, unnecessary switching times can be reduced, and the time delay caused by switching can be reduced.

Description

technical field [0001] The present invention relates to the technical field of multi-connection network switching, in particular to a switching method, device and LTE base station suitable for multi-connection networks. Background technique [0002] Currently, in a multi-connection system, the control plane is separated from the user plane. like figure 1 As shown, on the control plane, all RRC (Radio Resource Control, radio resource control protocol) signaling information required by the user equipment, such as public radio resource configuration, dedicated radio resource configuration, measurement and mobility management, etc., are provided by LTE ( Long Term Evolution, long-term evolution) base station is responsible, and the user equipment only responds to the RRC message to the LTE base station; on the user plane, only the LTE base station is connected to the core network, and all downlink data streams are first sent to the LTE base station, and then passed through the ...
