通信系统和通信方法及其交换中心和基站控制台技术方案

本发明专利技术提供了一种ＷＣＤＭＡ通信系统，该通信系统即使在因资源不足而不能确保与用户期望的通信服务对应的通信速率时，也能顺利进行数据传输。当因资源不足而不能确保期望的通信速率时，不是强制性地设定为更低的替代的通信速率，只有在基站控制台（２－１，２－２）才可使用比请求通信速率低的通信速率来提供服务的情况下，才在交换台（１）和基站控制台（２－１，２－２）之间对实际用于数据通信的通信速率进行调整。作为该方法，在从交换台（１）发送到基站控制台（２－１，２－２）的ＲＡＢ设定请求中设有指示通信速率可调／不可调的指示符。只有在该指示符指示通信速率可调的情况下，基站控制台才会在资源不足时决定比期望通信速率低的通信速率，并将在ＲＡＢ设定响应包含的该决定的通信速率中发送到交换台（１）。根据该通信速率，开始用户终端（４）的通信服务。（*该技术在2021年保护过期，可自由使用*）

Communication system and communication method, and switching center and base station console thereof

The present invention provides a WCDMA communication system capable of carrying out data transmission smoothly even when the communication rate corresponding to the communication service required by the user is not guaranteed due to insufficient resources. When due to a lack of resources can not ensure the desired communication rate, it is not mandatory to set lower alternative communication rate, only in the base station console (2 - 1, 2 - 2) can be used to provide the service communication request rate low communication rate than the case in Taiwan exchange (1) the console and the base station (2 - 1, 2 - 2) of actual data communication for communication rate adjustment. As the method, from the exchange in Taiwan (1) sent to the base station console (2-1, 2-2) indicator RAB setting request with adjustable / adjustable indicating communication rate. Only can be adjusted in an indicator indicating the communication rate under the condition of lack of resources in the base station console will determine the desired communication rate than the low rate of communication, the communication rate and set the decision contained in the RAB response sent to the exchange (1). The communication service of the user terminal (4) is started according to the communication rate.
