Method, system and multi-mode terminal for implementing network selection in multi-standard communication network

Abstract

The invention discloses a method, a system and a multimode terminal for the realization of the network selection in a multi-system communication network. When a network selection control entity is configured in the multi-system communication network and the multimode terminal needs services, the network selection control entity controls the multimode terminal to selectively access a network according to the configuring selection policy and the obtained selection reference information, and the multimode terminal carries out services via the selected access network. According to the proposal provided by the invention, a suitable access network can be determined to supply the service connection for the multimode terminal by combining the selection policy with the selection reference information according to the relevant information of the access network such as the load condition, so as to make the appropriate access network bear appropriate subscribers and services and ensure reasonable use of network resources. Accordingly, the multi-system networks can be matched with each other in a cooperation mode so as to economize the network resources and guarantee the economy of the construction of the multi-system communication network.

Description

technical field [0001] The invention relates to the field of multi-standard communication networks, in particular to a method, a system and a multi-mode terminal for realizing network selection in a multi-standard communication network. Background technique [0002] In order to meet the requirements of wireless application scenarios and diversified services, wireless access technologies are becoming increasingly diversified. Due to users' demands for ubiquitous wireless services and business experience, wireless access technologies and networks targeted at different wireless application scenarios and services can develop in diversification and coexist and complement each other for a long period of time. Various wireless access technologies and networks have unique advantages in adaptability to wireless application scenarios and service deployment. For example, the supporting services of wide-area coverage are mainly voice and low-to-medium-rate data services, and supporting...

Problems solved by technology

In a multi-standard communication network, it is contrary to the ease of use for business development to allow users to understand which access networks are available in their environment, and the support capabilities of each access network for services, so as to select the appropriate network. sometimes even unrealistic

In addition, in order to facilitate users' understanding, multi-mode terminals are required to convert specific standard connections into more intuitive information, which is very inconvenient in practical applications and affects the convenience of service deployment and user experience

And because the user manually selects, it is not controlled by the network side, and cannot be selected according to the actual situation of each access network, such as the load condition

[0006] When a multi-mode terminal selects the default connection as the connection for business according to the configuration, it is directly selected according to the configuration,
