Method and base station controller for optimized access control

Abstract

The invention discloses a method for optimizing access control and a base station controller. The method for optimizing access control includes the following steps that: when it is detected that no data transmission exists between an access network and an access terminal, an air interface dormancy timer and an interface dormancy timer are started; If the air interface dormancy timer does not receive a data transmission request associated with the access terminal before time-out, air interface wireless connections between the access network and the access terminal are released; and if the interface dormancy timer receives a data transmission request associated with the access terminal before time-out, air interface wireless connections between the access network and the access terminal are re-established, so that packet data can be transmitted between the access terminal and a packet data service node. With the method for optimizing access control and the base station controller of the invention adopted, a large quantity of signaling interaction of A interfaces among a BSC and a PCF and a PDSN network element at a network side can be avoided, and signaling load of the network side can be reduced.

Description

Technical field [0001] The present invention relates to the field of communications, and in particular to a method for optimizing access control and a base station controller. Background technique [0002] With the development of mobile Internet and smart terminals, mobile Internet business applications are becoming increasingly abundant. Among mobile Internet business data interaction methods, "always online" is a mainstream application interaction method, such as currently commonly used mobile phone QQ, MiLiao, Weibo, etc. This type of application has the characteristics of small traffic per unit time and long online time. Features, often referred to as "small traffic and long online" business. Since the "low traffic and always online" service requires terminals to frequently reestablish signaling connections, it will cause problems such as increased network signaling load. [0003] In the HRPD (High Rate Packet Data) communication system, in order to promptly release th...

AI Technical Summary

Problems solved by technology

[0036] From the above content, it can be seen that for long-term online services with small traffic, the following problems exist in the signaling interaction of the A interface of the existing HRPD network: the terminal frequently switches between the dormant state and the active state, and the A9 interface on the network side needs to frequently establish and release the A8 connection, and the A11 The interface requires frequent registration requests (lifetime, charging data) and registration responses, which greatly increases the signaling load of BSC, PCF and PDSN
