Method, system and device for network handover

摘要

A method, a system and a device for network handover are provided, which are applied to the field of communications technologies. The method includes the following steps that: a terminal first obtains information of a handover manner of handover from a virtual base station to a target base station, and then sends a corresponding message to the virtual base station according to the information of the handover manner, so as to perform network handover, so that in a procedure that the terminal is handed over from a non-WiMAX network to a WiMAX network, the terminal may be directly handed over according to the handover manner supported by the virtual base station. Compared with the conventional art in which handover manners require handover attempts, the adoption of the method for network handover reduces handover time and increases network handover efficiency.

1. A method for non-WiMAX (Worldwide Interoperability for Microwave Access) network to WiMAX network handover, comprising:
obtaining by a terminal from an information server, information of a non-WiMAX network to WiMAX network handover manner of the terminal being handed over from a virtual WiMAX base station to a target base station, wherein the information of the non-WiMAX network to WiMAX network handover manner is supported by the virtual WiMAX base station, and the information of the non-WiMAX network to WiMAX network handover manner comprises at least one of information indicating initiate handover and information indicating idle mode handover; and sending by the terminal, a corresponding message to the virtual WiMAX base station according to the information of the non-WiMAX network to WiMAX network handover manner, so that the terminal is handed over from the virtual WiMAX base station to the target base station according to the information of the non-WiMAX network to WiMAX network handover manner; and wherein the obtaining the information of the non-WiMAX network to WiMAX network handover manner of the terminal being handed over from the virtual WiMAX base station to the target base station comprises:
sending a query request message to the information server, wherein the query request message comprises at least one of position information of the terminal and identifier information of the target base station, so that the information server locates, according to the position information, a base station available for the terminal and the virtual WiMAX base station capable of interacting with the base station; or the information server locates, according to the identifier information of the target base station, the virtual WiMAX base station capable of interacting with the target base station; and
receiving a query response message, wherein the query response message is returned by the information server in response to the query request message, wherein the query response message comprises the information of the non-WiMAX network to WiMAX network handover manner of the terminal being handed over from the virtual WiMAX base station to the target base station.
