Problems solved by technology

When the monitoring mechanism detects a sudden abnormality, if the reverse carrier CDMA channel that the AT independently selects to delete is carrying control information for some forward carrier links, then the deletion of the reverse carrier CDMA channel will make the forward carrier chain The control information of the link is lost, which affects the data transmission of the forward carrier link
If the AT avoids this situation by selecting an algorithm, the selection algorithm will greatly limit the implementation flexibility of the reverse link monitoring and management mechanism

Embodiment Construction

[0042] The core of the present invention is to select at least one reverse carrier link from each reverse carrier link of the wireless access terminal when detecting abnormal reverse transmission of the wireless access terminal, keep the selected reverse carrier link, and The predetermined channel of the selected reverse carrier link is in the state of stopping transmission, and the selected reverse carrier link is monitored and managed according to the predetermined condition of maintaining the selected reverse carrier link.

[0043] The technical solution provided by the present invention will be further described below based on the core idea of ​​the present invention.

[0044] In the EV-DO system, each reverse carrier link of the wireless access terminal is based on the mechanism of code division multiplexing. For example, the wireless access terminal multiplexes the pilot channel, MAC channel, ACK channel and traffic channel in the Transmitting together at the same time, ...

Abstract

This invention provides one reverse wave load monitor management method and device, which comprises the following steps: interfacing terminal AT reverse emission to wireless network and taking at least one reverse load linkage from each direction of AT to keep selected reverse load wave linkage and to make the reverse linkage signal at stop emission status; according to reverse linkage preset condition, processing reverse load linkage monitoring. This invention can avoid burst interference reverse load linkage deletion phenomenon.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a reverse carrier link monitoring and management method and device. Background technique [0002] At present, 3G mobile communication technology is gradually mature and commercially available. 3GPP2 (Third Generation Mobile Communication Cooperation Project Organization 2) CDMA2000 1XEV-DO (Evolution, Evolution, Data Only, only supports packet data services) will further provide competitive services in the next few years. wireless access system. [0003] 1XEV-DO technology is a technology used to transmit high-speed packet data services. The maximum peak rate supported by each sector carrier frequency can reach 2.4Mbps. In version A, the peak rate can reach 3.1Mbps. However, in order to maintain competitiveness in the next decade or decades, it is necessary to introduce new wireless access technologies. [0004] At present, the industry has reached a preliminary c...
