    • A method and a system is disclosed for controlling a sleep mode in broadband wireless access communication system. The subscriber terminals are managed by grouping the subscriber terminals in a broadband wireless access communication system, so an efficiency for controlling the sleep mode of the broadband wireless access communication system may increase. A further advantage is provided that each point of time for transmitting a paging message of each group is established differently from each other within a unit time slot for controlling the sleep mode, such that subscriber terminals are managed according to groups. Another advantage is provided that the base station can previously find subscriber terminals awaking at each point of time for transmission the paging message of each other from among subscriber terminals having the sleep mode, so an efficiency for controlling the sleep mode of the broadband wireless access communication system may increase.
    • 公开了一种用于控制宽带无线接入通信系统中的睡眠模式的方法和系统。 通过在宽带无线接入通信系统中对用户终端进行分组来管理用户终端,因此可以增加用于控制宽带无线接入通信系统的睡眠模式的效率。 另外的优点是,用于发送每组的寻呼消息的每个时间点在用于控制睡眠模式的单位时隙内彼此不同地建立,使得用户终端根据组来管理。 另一个优点在于,基站可以预先找到在每个时间点唤醒的用户终端,以从具有睡眠模式的用户终端之间传输彼此的寻呼消息,从而控制宽带无线接入通信的睡眠模式的效率 系统可能会增加。

    • A power saving mode is provided. A method for entering a power saving mode of a terminal includes a first operation for starting a first timer after transmitting an idle mode request message; a second operation for, when an idle mode approval message is not received until the first timer expires, checking whether a number of retransmissions of the idle mode request message exceeds a number of allowed retransmissions of the idle mode request message; a third operation for, when the number of the retransmissions of the idle mode request message exceeds the number of the allowed retransmissions of the idle mode request message, increasing a number of idle mode entry failures; and a fourth operation for, when the increased number of the idle mode entry failures is greater than N times, entering a power saving mode which powers off a modem.
    • 提供省电模式。 用于进入终端的省电模式的方法包括:在发送空闲模式请求消息之后启动第一定时器的第一操作; 第二操作,当在所述第一定时器到期之前没有接收到空闲模式批准消息时,检查所述空闲模式请求消息的重发次数是否超过所述空闲模式请求消息的允许重发次数; 第三操作,当所述空闲模式请求消息的重发次数超过所述空闲模式请求消息的允许重发次数时,增加空闲模式进入故障的数量; 以及第四操作,当空闲模式进入故障的数量增加大于N次时,进入关闭调制解调器的省电模式。
