Method, system and detecting device for controlling system high load

Abstract

The method includes steps: obtaining information of access terminal, based on obtained information to determine the access terminal causing high load of system; releasing the calling from the access terminal causing high load of system. The system includes access terminal, detection equipment, and access network. The detection equipment is in use for determining the access terminal causing high load of system. The invention guarantees normal operation of system.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a method, system and detection device for controlling high load of a system. Background technique [0002] With the rapid development and wide application of mobile communication technology, CDMA2000 in Code Division Multiple Access (CDMA) technology has become the fastest commercial progress in the third generation mobile communication technology, and its evolution technology - High Speed ​​Packet Data (HRPD) ), has also gained increasing attention. [0003] In the HRPD system, the access terminal (AT) has a powerful AT command set. For example, the AT command at$qchdrr=N can be used to fix the reverse rate, where N is an integer value from 1 to 5, indicating that the rate is fixed. for 2 N-1 Times times 9.6kbps, the user can realize the fixed reverse upload rate of AT through this AT command. However, the fixed reverse rate has a great impact on the forward and reverse ...

AI Technical Summary

Problems solved by technology

This method can automatically adjust the rate according to the system status, but it does not work for AT with a fixed reverse rate

[0012] The second, broadcast or unicast reverse rate limiting method

However, when the fixed reverse rate of the upload data service set by the AT command exceeds the set value of the broadcast or unicast reverse rate limit, the actual data transmission rate is still the fixed rate of the terminal AT command. If the system has a high load at this time , the existing two methods of controlling the high load of the system by limiting the reverse rate cannot achieve control

[0015] In addition, abnormal power AT can also cause high system load. The existing two methods of controlling high system load by limiting the reverse rate obviously cannot solve the problem of high system load caused by abnormal power AT.
