Radio base station resource allocation method and radio base station

Abstract

By allocating resources so as to minimize call losses, both capacity efficiency and load distribution improvements can be achieved. Set the calls to be protected and modify the resource allocation method according to the resource status of each card. Call distribution processing is performed as follows. When the traffic volume is low, load distribution is performed, and when the traffic volume is high, the resources of the high-usage cards are exhausted. Therefore, load distribution among signal processing cards can be obtained by efficiently using resources and minimizing call losses.

Description

technical field [0001] The present invention relates to a resource management scheme suitable for allocating resources in a wireless base station holding terminals performing wireless communication. Background technique [0002] In recent years, cellular phones have been widely used, and the cellular phone service in the W-CDMA (Wideband Code Division Multiple Access) standard was first started in Japan in 2001. As far as communication technology is concerned, digital cellular phones only provide voice and low-speed packet communication, while the introduction of W-CDMA allows broadband transmission, such as the 384kbps service that started in 2002. [0003] A network of W-CDMA includes switching devices, RNC (Radio Network Controller), BTS (Base Transceiver Station) and the like. The BTS performs wireless communication with cellular phone terminals, and converts signals into signals for a network. Various applications utilizing broadband transmission are provided in W-CDM...

Problems solved by technology

However, in the algorithm of the above-mentioned patent document, since the existence of the common channel is not considered, even when there are vacant resources capable of accommodating the common channel in the entire base station, it is impossible to allocate the common channel to other resources due to the distribution of the vacant resources. resource

Therefore, when the common channel fails, the communication between the terminal and the base station may be disconnected even during the communication with the terminal
