Problems solved by technology
[0003] Based on the current network architecture, handover between systems often requires complex signaling interaction to ensure that the complexity of the signaling process reduces the success rate of handover, and the resulting long handover delay affects user experience.
According to our current test situation, the delay in the CDMA and LTE handover scenarios following the 3GPP standard handover process has reached 5-10s. It is foreseeable that in the future 5G network, the handover time of multiple access heterogeneous networks The delay will not be an optimistic figure, it will seriously affect the user's business experience

The invention discloses a method and a system for mobile network switching. The method comprises the following steps: a mobile management module receives a switching request, and sends the switching request to a radio resource management module; the radio resource management module allocates spare vent physical resources according to the vent physical resource information of a base station, which is obtained from a centralized control module, and returns the allocated vent physical resources to the mobile management module; the mobile management module sends a switching instruction to the centralized control module, and then sends the switching instruction to the target base station under the centralized control module. According to the method and the system disclosed by the invention, hop-by-hop signalling forwarding is avoided, signalling switching is simple, a switching process can be shortened, and a switching success rate is increased.
Description
technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a mobile network switching method and system. Background technique [0002] With the gradual evolution of mobile networks, multiple wireless access technologies must coexist and jointly provide users with access services. The coordination and management of heterogeneous networks under multiple wireless access technologies will be a problem, such as how to reduce the signaling and delay of handover in cross-RAT (radio access technology) scenarios, and ensure the continuity of user experience (QoE) ; How to better allocate resources under the multi-access system to achieve the maximum utilization of resources. [0003] Based on the current network architecture, switching between systems often requires complex signaling interactions to ensure that the complexity of the signaling process reduces the success rate of switching, and the resulting long switching del...
