[0065] The first embodiment provided by the present invention, as shown in Figure 2, includes:

[0066] Step 1. The terminal detects the surrounding access network, and selects each type of network that can be accessed according to business requirements, and each target access point that can access the type of network, and then sends a handover initialization request to the service access point message, and send the selected network type and the identification information of the target access point accessing the type of network to the service access point through the suggested network type list and the suggested target access point ID list carried in the message entry point.

[0067] The message also carries the upper-layer mobile protocol of the service access point, the command type (local / remote), the network ID of the service access point, the command transport layer (L2 / L3), the switching mode, and the link behavior of the current access network information. as shown in...

[0099] The fourth embodiment provided by the present invention differs from the third embodiment in that step 4 and step 5:

[0100] In step 4, after receiving the response message fed back by each target access point, the service access point obtains the available resource information fed back by each target access point, and then compares it with the network type suggested by the terminal and the target access point, Select consistent information therefrom, then sort the selected target access points according to service quality (QoS) or service price, and save them in the preferred network type list and the preferred target access point list, Then send to the terminal by handover initialization request response message.

[0101] In step 5, after receiving the message sent by the network, the terminal selects a target access point and network type to be accessed, and then sends a handover execution request to the target network through the target access point.

Abstract

This invention relates to a switch method among isomeric networks by terminals including: a service access point receives an initialized request of switch, it requires resource distribution information to an adjacent target access point and selects multiple available target access points and their corresponding access networks to send them to the terminal for switching, in which, a terminal can select multiple target access points and their corresponding access networks, and when the terminal is ready for switch, it can set up links with the target access points and the corresponding networks so as to increase probability of successful switch.

Description

technical field [0001] The present invention relates to the field of communication, in particular to the switching of terminals between heterogeneous networks. Background technique [0002] With the rapid development of communication technology, multiple heterogeneous networks coexist, and the problem of seamless switching of terminals between existing heterogeneous networks has become increasingly prominent. [0003] Changes in the channel environment, user movement, selection of different services, etc. may lead to switching between networks. In order to realize the seamless handover of terminals between heterogeneous networks, the concept of media-independent handover is proposed. experience. [0004] Media-independent switching is mainly realized through media-independent services, and the media-independent services include: [0005] 1. Media-independent event service, including events and triggers generated by local and remote interfaces. [0006] 2. The media-indep...
