Problems solved by technology

[0007] However, the throughput rate cannot accurately measure the quality of the air interface. This is because when the amount of data in the cache is very small, the data that can be sent out in a time interval is less than the amount of data that the channel bandwidth can carry. If the throughput is calculated at this time A smaller value will be obtained, and it may be concluded that the quality of the air interface is poor, but the actual situation is not necessarily the case; moreover, sometimes the high-priority traffic will occupy the resources of the low-priority business after the increase , so that the rate of services with lower priority is reduced, and the measured throughput is also small,

Example Embodiment

[0049] In mobile communication systems, such as WCDMA (Wideband Code Division Multiple Access), the downlink code transmission power refers to the average power of the pilot bits on the downlink dedicated physical channel, and the downlink code transmission power can reflect the air interface load. When the air interface load becomes lighter, the interference received by the user becomes smaller, and the signal-to-interference ratio of the data received by the user will be improved. If the quality of the received data is very good, it is expressed as the measured signal-to-interference ratio If the value is higher than the expected target value, then the downlink code transmission power will be reduced by one level through the inner loop power control; on the contrary, if the air interface load becomes larger, the user will suffer more interference and the quality of the received data will change. Poor, manifested as a decrease in the signal-to-interference ratio. When it is lower...

Abstract

The dynamic channel bandwidth allocating method includes determining aerial interface quality based on the emitting power of the downstream code, and re-allocating the channel bandwidth of best effort (BE) business according to the aerial interface quality. Adopting the emitting power of the downstream code as the criterion of interface quality can reflect the aerial interface status precisely. Therefore, the present invention can meet the requirement of user in quality of service (QoS) as possible under the condition of allowed resource on one hand and limit the transmission rate of BE service under limited resource condition to maintain system stability on the other hand.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method for dynamically configuring channel bandwidth. Background technique [0002] With the development of network communication technology, wireless terminal devices in wireless communication systems, such as mobile phones, also provide Internet access functions accordingly. Users can enjoy WWW (World Wide Web) browsing and FTP (Text Transfer Protocol) provided by the Internet in a wireless state. ) download and E Mail (e-mail) and other services. This type of service has low requirements on delay, but the source data rate varies greatly. For example, when a user clicks on a WWW page connection, a page download request is sent, and one or more packet sequences will be sent. At this time, the channel There will be a large amount of data that needs to be transmitted quickly; when the download is completed, the user needs to spend a certain amount of time to read, and the...
