    • A system and method of controlling a data rate of a user equipment (UE) for a packet data service in a mobile communication system is provided. In the system and method, a radio access bearer (RAB) assignment request message comprising maximum rate information is received. The maximum rate information indicates a requested data rate for the packet data service. An initial data rate is set to the requested data rate, and it is determined whether the initial data rate is available by checking available resources. If the initial data rate is not available, it is determined whether the initial data rate is the lowest of a plurality of levels of predetermined data rates. If the initial data rate is the lowest level, a RAB is established in a common channel state. If the initial data rate is available, a RAB is established at the initial data rate in a dedicated channel state.
    • 提供了一种在移动通信系统中控制分组数据服务的用户设备(UE)的数据速率的系统和方法。 在系统和方法中,接收包括最大速率信息的无线电接入承载(RAB)分配请求消息。 最大速率信息表示分组数据业务的请求数据速率。 将初始数据速率设置为所请求的数据速率,并且通过检查可用资源来确定初始数据速率是否可用。 如果初始数据速率不可用,则确定初始数据速率是否是预定数据速率的多个级别中的最低数据速率。 如果初始数据速率是最低级别,则RAB建立在公共信道状态。 如果初始数据速率可用,则以专用信道状态的初始数据速率建立RAB。
