Method, system and server for implementing domain selection in communication system

Abstract

The invention discloses a method and a system for realizing domain selection in a communication system, and an IMS general domain selecting server. The method includes the steps of: at first, acquiring a domain selecting strategy at a terminal side and the domain selecting strategy at a network side; carrying out the domain selection according to the acquired domain selecting strategy at the terminal side and the domain selecting strategy at the network side. The system of the invention includes a domain selecting strategy storing unit at the terminal side, a domain selecting strategy storing unit at the network side, a domain processing unit and a domain selection execution unit. The IMS general domain selecting server provided by the invention includes a domain information exchange unit at the terminal side, the domain information exchange unit at the network side and a domain decision-making unit. The invention can guarantee that the selected domain can meet the requirements of the user equipment and the service at the network side, thus considerably improving the overall performance of the system.

Description

technical field [0001] The invention relates to network communication technology, in particular to a method, system and server for realizing domain selection in a communication system. Background technique [0002] With the development of communication technology, the interconnection among mobile network, fixed network and Internet has become the current trend of network development. In view of the development trend of network interconnection and intercommunication, an IP Multimedia Subsystem (IMS) has appeared at present. The IMS network is a network subsystem introduced on the basis of the packet bearer network to complete IP multimedia communication control. It can face multiple access technologies, shield user access methods according to personalized user data, control the degree of openness of service capabilities, and provide The communication experience of IP multimedia has fundamentally changed the vertical structure of one service and one network in traditional net...

Problems solved by technology

Moreover, when the network side selects a service domain, it may not consider the current service requirements of the terminal side. In this way, the finally selected service domain cannot meet the service requirements of the UE and the network side at the same time, and cannot improve the overall performance of the system.

For example, the network side selects the CS domain as the service domain to provide services for the UE according to the load balancing requirements, but the UE does not want the CS domain to obtain business services due to the consideration of service costs, so it cannot meet the service requirements of the UE side and reduces the system's service requirements. overall performance

[0007] 3. At present, only a specific implementation scheme for selecting between the IMS domain and the CS domain is provided. However, with the rapid development of communication technology, the types of access domains and service domains are not limited to IMS domains and CS domains. For example, Currently, there are networks such as Worldwide Interoperability for Microwave Access (Wimax), fixed broadband access such as Digital Subscriber Line Multichannel Access (DSLAM) networks, and IP-based cable television networks such as Packet Cable networks Therefore, the method that can only be implemented in the IMS domain and the CS domain, which can be realized by the existing technology, also greatly reduces the flexibility of service implementation, limits the development of services, and reduces the business service quality
