Configurating method and apparatus for channel band width in telecommunicating system

Abstract

The method includes following steps: the target channel band width of user terminal is acquired; according to the target channel band width conforming to preset conditions, the down stream band width of the above user terminal is set again. The device consists of: the target channel band width acquired module, the target channel band width determined module; the channel band width reset up module.

Description

Technical field [0001] The invention relates to the technical field of network communication, in particular to a method and device for configuring channel bandwidth in a communication system. Background technique [0002] With the continuous rapid development of network communication technology, services that people had to implement in a wired state, such as Internet services, can now also be implemented in a wireless state. All kinds of handheld mobile devices can provide high-speed interconnection access function. This technical advantage is particularly obvious in 3G (third-generation mobile communications). For example, some terminal devices in WCDMA (Wideband Code Division Multiple Access) systems can provide High-speed interconnection access function, its data transmission rate can reach at least 2Mbps in indoor static environment, and its data transmission rate can reach at least 384kbps in indoor and outdoor walking environment. [0003] Among various wireless Internet ac...

Problems solved by technology

[0007] To sum up, the method for reconfiguring the downlink channel of the user terminal in the prior art only considers the downlink transmission power status of the user terminal under the current bandwidth when increasing the bandwidth of the user terminal, and does not Considering whether the downlink transmission power of the user terminal configured to the target bandwidth can meet the service requirements of the user terminal at the same location, if not, it will lead to call drop or reduce the downlink channel bandwidth again, resulting in the oscillation of downlink channel bandwidth reconfiguration

Moreover, when increasing the bandwidth of the downlink channel for the user terminal, it is not considered that the increase of the system load will lead to admission rejection, that is, when the system load is not allowed to increase, the existing method will no longer negotiate the bandwidth of the downlink channel, reducing a certain amount of time. The target channel bandwidth reconfigures the downlink channel bandwidth for the user terminal

At the same time, in the prior art, when the bandwidth of the downlink channel is increased for the user terminal, the increase of the bandwidth of the downlink channel is not considered, the increase of the system load will cause the system to enter a congested state, thereby affecting the stability of the communication system
