Method/system, access point equipment and terminal equipment for switching initialization between heterogeneous networks

Abstract

The invention relates to a method for switching initialization between heterogeneous networks, which comprises the following steps: sending a switching candidate inquiry request carrying user requirements to the current access point by a terminal; inquiring available resources of each candidate access point and determining effective access points by the current access point; sorting the effectiveaccess points according to the user requirements by the current access point; using the first effective access point after sorting as a target access point by the current access point, and feeding the switching candidate inquiry response including the object access point back to the terminal; and directly carrying out switching operation by the terminal through the object access point fed back. By adopting the method, the network side can select the most appropriate object access point according to the user requirements to avoid the occurrence of the inconsistent condition of user selection and network selection, thereby bringing good switching feeling for users. The invention also provides a system, access point equipment and a terminal for switching the initialization between heterogeneous networks.

Description

technical field [0001] The present invention relates to mobile communication technology, in particular to a method and system for handover between heterogeneous networks, and an access point device / terminal device for initialization of handover between heterogeneous networks. Background technique [0002] The next-generation mobile wireless network will be an all-IP network that carries integrated services such as voice, data, and multimedia, and where multiple wireless access technologies coexist. With the widespread use of personal digital terminals supporting multiple wireless access technologies, it is foreseeable that the next generation of user terminals will have a variety of different wireless air interface standards, and the networks of these different technologies may belong to different operators or service provider. Therefore, it is becoming more and more important to study the seamless mobility management and smooth handover mechanism of mobile terminals betwee...

Problems solved by technology

[0007] According to the existing technical solution, after the user sends a handover candidate query request to the current POA at the terminal, since the current POA can select a better handover target network and target POA based on the network side's understanding of the candidate network and POA information, Replace the target network and target POA suggested in the handover candidate inquiry request, and perform the initialization operation with the new target network and target POA, resulting in the fact that the final handover target network and POA are inconsistent with the user's choice

For example, the user selects WLAN as the target network for handover at the terminal. On the network side, the current POA selects a more suitable target network WiMAX and its POA according to the available resources of each candidate POA to replace the target network suggested in the handover candidate inquiry request. Network WLAN and its POA, and initialize the handover with the new target network WiMAX and its POA. In this way, when the handover is finally completed, the user will find that the network WiMAX used by the terminal after handover is inconsistent with the network WLAN he selected, which will cause user inconvenience. to feel bad
