Embodiment Construction

[0046] The present invention provides a method for handover judgment between multiple access networks. The core of the present invention is: the upper layer application of the user terminal obtains the load information of each cell in the access network, and uses the load information as a reference to the user terminal. Auxiliary information for handover decision.

[0047] The method of the present invention will be described in detail below in conjunction with the accompanying drawings. Taking the communication system based on the IEEE 802 standard as an example, the specific processing flow of the embodiment of the method of the present invention is as shown in Figure 4, including the following steps:

[0048] Step 4-1. The MIH User periodically sends a command carrying a cell load information request to the user terminal and the network.

[0049] The present invention first needs to add a cell load information request in the GetStatusRequestSet or Link_Get_Information comma...

Abstract

The provided fast deciding method among multiple access networks comprises: the MIH User obtains the subzone loading message as the assist message for accurate MIH switch decision. This invention works well in a communication system based on IEEE 802 standard.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a method for switching judgment among multiple access networks. Background technique [0002] At present, various communication technologies are developing rapidly, which makes roaming switching and network selection among various communication systems more prominent. In order to solve the roaming handover problem of users among communication systems such as IEEE (Institute of Electrical and Electronics Engineers) 802.11, IEEE 802.15, IEEE 802.16, 3GPP (Third Generation Partnership Project), 3GPP2, etc., the IEEE 802 wireless working group established the IEEE802 Handover Research Group - Handoff ECSG. Handoff ECSG was later officially named IEEE802.21. IEEE 802.21 is mainly responsible for formulating a public switching framework, standardizing the requirements for switching between software and hardware between different systems and the corresponding switching mechanism. ...
