Method and system for IP service capability negotiation of WiMAX network

Abstract

The invention discloses a method and a system for IP service capability negotiation of a WiMAX network. In a mode of attaching user-preferred IP service capability mode information to initial user registration information, by accessing service transaction and network IP capability negotiation between an access service network and a home service network, the home service network can make an authorization strategy decision according to the user-preferred IP service capability information, business needs of a service provider, a user-signed database, a network architecture and the capacity of a network entity. The method and the system overcome the defect that a mobile terminal does not support the authorization mode of the home service network decision because the mobile terminal does not participate in the current IP service capability authorization mode.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a method and system for negotiating WiMAX network IP service capabilities. Background technique [0002] Worldwide Interoperability for Microwave Access (WiMAX for short) technology is a broadband wireless access standard. figure 1 is a schematic diagram of the logical architecture of the existing WiMAX network participating in quality of service assurance, such as figure 1 As shown, in the WiMAX system, it includes a home service network (Home Connect Service Network, referred to as H-CSN), a visiting service network (Visit Connect Service Network, referred to as V-CSN), an access service network (AccessService Network) , referred to as ASN). [0003] Network nodes that provide users with service flow operations mainly include: Service Flow Management (SFM for short) module, Service Flow Authorization (SFA for short) module and Policy Function (PF for short) module ; Whe...

Problems solved by technology

[0015] It can be seen from the above description that the user does not participate in the decision-making process of the IP service capability authorization policy, that is to say, the user's IP service capability information is not used as the home service service network to determine what IP service capability to provide for the user. According to the basis, it may lead to the situation that the IP service mode authorized by the home service service network based on the access service network, visit service service network, subscription information, and its own IP service capability information is not supported by the mobile terminal, so that although the user accesses Network but can’t use the service, or the service service network authorizes multiple IP modes to access the service network, need to access the service network and then make a judgment on the selection of IP service mode based on user information
