Method for controlling user access in wireless network

Abstract

The method includes following steps: the resources of SGSN of GPRS are divided into several parts; based on the subscription network and the access network users belong to, distinguishes different access type; sets the condition of limiting the use of each part resource for different access type user. When user initiates an access request, takes following steps: a) the network recognizes the access type of user; b) compares the limiting conditions of each part resource currently used by the access type, and selects one part of them to complete the user access.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for controlling user access in a wireless network. Background technique [0002] In order to solve the problem of low transmission rate of GSM system in digital communication, GSM system adds General Packet Radio Service (GPRS) on the basis of the original system, so that the maximum rate of GPRS data transmission reaches 115kbit / s, The GPRS system is the transition from the GSM system to the 3G system, and when the GSM system develops to 3G, it is WCDMA. [0003] In the existing mobile communication system, the WCDMA+GPRS network co-construction technology is currently used, in which the GPRS business support node SGSN (Service GPRS Support Node) completes functions such as security management, access control and data packet routing, and participates in GPRS A PDP (Packet Data Protocol, data packet protocol) activation process for network subscribers and WCDMA network subscri...

AI Technical Summary

Problems solved by technology

For example, abnormal billing of WCDMA services may cause loss of GPRS user bills; abnormal user control of WCDMA services may cause GPRS network to be unusable, etc.

This often leads to a decline in service quality for legacy GPRS users and reduces the value of the GPRS network

With the continuous popularization of WCDMA services, there will be a situation where the network resources used by GPRS access users + WCDMA access users will cause SGSN resource congestion, and cause the service quality of GPRS access users and WCDMA access users to decline at the same time, and operators Inability to selectively control resource allocation status

For example: considering that GPRS users are often attached to the network and do not use GPRS services, SGSN should be able to limit the number of GPRS users attached to the network

At the same time, with the increase of WCDMA users and GPRS trial WCDMA network users, it will also lead to resource congestion in SGSN, which will lead to the decline of service quality of WCDMA subscribers and cause user dissatisfaction

It is also inappropriate to completely refuse GPRS users to try WCDMA network, which will reduce the effect of cultivating user habits, and will also bring greater economic losses
