Method and system for acquiring user priority attributes in multi-access system

Abstract

The invention discloses a method and system for acquiring user priority attributes in a multi-access system. The method includes: when authenticating a user equipment UE connected to the network, the access control network element sends the Add the UE user priority request identifier in the authentication request message, the authentication server adds the UE user priority attribute information in the authentication success message sent to the access control network element; the access control network The unit acquires and stores the UE user priority attribute information. In the present invention, the user selects the priority attribute of the access network to perform pre-filtering, which reduces the signaling overhead and the pressure of the LMA.

Description

technical field [0001] The present invention relates to a technology for obtaining user priority attribute information, in particular to a method and system for obtaining user priority attribute information in a multi-access system. Background technique [0002] With the development of communication networks and the widespread use of multi-mode terminals, various data services have developed rapidly, such as web browsing, online games, media on demand and other data service traffic has exploded; The higher the increase, the more pressure on the network of operators, and the problem of network congestion is becoming more and more serious. Wireless Local Area Network (WLAN, Wireless Local Area Network) is favored by many operators due to its low cost, high bandwidth, and good hotspot coverage. As a supplementary means, in the aspect of data service distribution, it can help operators solve the problems of excessive data traffic on the 3G network, excessive occupation of wirel...

Problems solved by technology

The currently proposed network-side flow migration trigger is triggered by the LMA based on conditions such as operator policies and user subscription attributes. However, since the LMA cannot know the specific information of the WLAN where the MN is located, if the If the WLAN signal strength is low or the WLAN load is already too large, if the LMA migrates service flows to the WLAN, the migrated flows may be lost, degrading user experience.

If accurate flow migration is required, the WLAN access network needs to report user-related WLAN information to the LMA, and when there are a large number of user terminals in the WLAN, a large amount of signaling overhead is required to report relevant information, and the LMA also needs to report the received Update, save, calculate and other processing of information, which greatly increases the pressure on LMA

Especially for users with different contracts, it will increase unnecessary resource overhead
