    • A plurality of consoles (111-113) share use of a single landline (101) with minimal requirements for internal maintenance data signalling. As two or more consoles both share use of the link, a telephone interface (103) assigns one of the consoles to be responsible for maintenance signalling. If and when the assigned console concludes its communication needs or otherwise becomes unable to continue the maintenance signalling, the telephone interface will assign a new interested console to provide the maintenance signalling. This continues until no consoles remain having an interest in maintaining the communication link. In one embodiment, when the link is used by only a single console, a hold function can be accommodated. When two or more consoles are serviced, however, the hold function is not applied. Also, when the link has been placed on hold, any console can remove the hold condition.
    • 多个控制台(111-113)共享使用单个固定电话(101),对内部维护数据信令的要求最低。 由于两个或多个控制台共享使用链路,所以电话接口(103)分配一个控制台来负责维护信令。 如果当分配的控制台完成其通信需求或以其他方式不能继续维护信令时,电话接口将分配新的感兴趣的控制台来提供维护信令。 这一直延续到没有任何控制台仍然有兴趣维护通信链接。 在一个实施例中,当链接仅由单个控制台使用时,可以容纳保持功能。 然而,当服务了两个或更多个控制台时,不应用保持功能。 此外,当链接已被搁置时,任何控制台都可以取消保持状态。

    • In a wireless communication system, session timers are separately maintained by a communication device (101) and a system controller (104). When a portion of outbound data is sent to a base station (102) for transmission to the communication device, the base station creates at least one transmission time stamp which is then sent to the system controller (203). If a session has not been previously established, the system controller uses the at least one transmission time stamp to establish a session and initiate a session timer (204). If a session has been previously established, the system controller uses the at least one transmission time stamp to determine whether to continue the current session timer (709). This applies to inbound data as well. Furthermore, session timers can also be synchronized to paging acknowledgments (305), channel information messages (503) or channel access messages (602). In this manner, session timers are more accurately synchronized.
    • 在无线通信系统中,会话定时器由通信设备(101)和系统控制器(104)单独维护。 当将一部分出站数据发送到基站(102)以传送到通信设备时,基站创建至少一个传输时间戳,然后发送给系统控制器(203)。 如果会话尚未建立,则系统控制器使用至少一个传输时间戳来建立会话并发起会话定时器(204)。 如果会话先前已经建立,则系统控制器使用至少一个传输时间戳来确定是否继续当前会话定时器(709)。 这也适用于入站数据。 此外,会话定时器还可以与寻呼确认(305),信道信息消息(503)或信道接入消息(602)同步。 以这种方式,会话定时器更准确地同步。
