Method for controlling operational states of a MAC layer in an OFDM mobile communication system
摘要：
A mobile communication system includes a medium access control (MAC) layer, and the MAC layer supports an idle state (719) in which no downlink and uplink dedicated control channel and dedicated traffic channel exists and also supports an active state (711) in which the downlink and uplink dedicated control channel and dedicated traffic channel exist. The MAC layer controls transitioning to a contention state (717) and then transitioning from the contention state (717) to the active state (711) through contention-based access, if there is transmission data in the idle state; transitioning to a fast access state (713) or a slow access state (715) according to priority of the data if there is no transmission data in the active state (711) for a preset time; transitioning to the active state (711) through contention-free-based access if there is transmission data in the fast access state (713); and transitioning to the active state (711) through contention-free-based access if there is transmission data in the slow access state (715).
摘要（中）：

移动通信系统包括媒体接入控制（MAC）层，MAC层支持没有下行链路和上行链路专用控制信道和专用业务信道的空闲状态（719），并且还支持活动状态（711），其中 存在下行链路和上行链路专用控制信道和专用业务信道。 如果存在处于空闲状态的传输数据，则MAC层控制转换到竞争状态（717），然后通过基于竞争的接入从竞争状态（717）转换到活动状态（711） 如果在预设时间内没有活动状态（711）中的传输数据，则根据数据的优先级转换到快速访问状态（713）或缓慢访问状态（715） 如果存在快速访问状态的传输数据（713），则通过基于无竞争的访问来转换到活动状态（711）; 并且如果存在处于慢速访问状态的传输数据（715），则通过无争用访问转换到活动状态（711）。
