Cross-domain heterogeneous network system and adjacent network switching method and device

Abstract

The adjacent network includes user terminal affiliated source network, one or more objective networks neighboring to source network. The switch management server (SMS) in source network is configured in service switching management server. The method includes steps: context-sensing server in source network collects and processes relevant context information (RCI) of user terminal; based on RCI to generate switching trigger event; RCI includes network information of source network, network information of target network, and terminal information; SMS in source network and SMS in target network to be switched to carries out switching management for the switching trigger event; under switching management, user terminal is switched to target network from source network. The invention also discloses a kind of switch equipment in use for isomeric network across domains, and isomeric network system across domains.

Description

technical field [0001] The present invention relates to the communication field, and more specifically, to a cross-domain heterogeneous network system and a handover method and device between adjacent networks. Background technique [0002] With the rapid development of communication technology, new communication technologies and standards emerge one after another, and the communication industry is experiencing a new period of development and transformation. In the process of communication network developing towards high-speed, broadband and personalization, a variety of wireless communication technologies and networks have emerged, including: 2G (GSM), 2.5G (GPRS), 3G (UMTS), WLAN, WiMax , PAN, fixed network, etc., which brings rich heterogeneity to the communication network, and heterogeneity will also be one of the main characteristics of the wireless network environment for a long time in the future. Therefore, research on the interworking and integration of heterogeneo...

AI Technical Summary

Problems solved by technology

[0009] (1) Handover technology between heterogeneous networks that mainly supports terminal triggering and decision-making, lacks support for vertical handover of network initialization and decision-making; because the terminal cannot completely collect relevant information of the network part, this leads to handover of terminal triggering and decision-making Cannot achieve optimal results

At the same time, this type of method also leads to complex terminal design, which needs to support multiple additional functions and a large number of calculations to provide triggering and decision-making for vertical switching, and has poor energy saving performance;

[0010] (2) The context-aware function and the reconfiguration function are isolated and independent, resulting in slow network initialization and low efficiency in the decision-making process;

[0011] (3) The function definition of the equipment for user switching management in the network is not clear enough;

[0012] (4) In the design of the terminal, a compromised multi-mode terminal is usually used, which is expensive and does not have versatility and scalability, and cannot meet the needs of users for ubiquitous and various types of network resource applications
