Switching method in network virtualization fog wireless access network

Abstract

The invention provides a switching method in a network virtualization fog wireless access network, being capable of reducing switching signal overhead. The method comprises the steps as follows: a source frog base station judges whether to execute an access switch, if the access switch is executed, the source frog base station sends a user access switch request to a target frog base station; the target frog base station sends command information of allowing user access and wireless resource distribution information to the source frog base station; the source frog base station sends system serial number information to the target frog base station, and forwards cache data to the target frog base station; the frog user is synchronized with the target frog base station, the target frog base station distributes an uplink resource and a tracking area to the frog user, and when the frog user accesses the target frog base station, the target frog base station receives a switch confirmation message from the frog user; and the target frog base station sends a path switching request to a preset virtual sub-group core network, wherein the virtual sub-group core network processes to complete switching. The method provided by the invention is applicable to a radio access network.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a switching method in a network virtualized fog wireless access network. Background technique [0002] With the rapid development of technical fields such as the mobile Internet, more and more users desire to access the Internet. At the same time, various types of base stations are deployed in large numbers, and the mobility of users in the network becomes one of the important issues in the future network system. The mobility of excess users, and the mobility between thousands of base stations cause a large number of handovers. The dense deployment of base stations and the frequent movement of users will lead to a large amount of handover signaling. How to reduce the impact of a large number of handover signaling on the network and reduce signaling overhead is an urgent problem to be solved.
