    • A method for managing data in a maintenance system of a digital cellular system which provides for the simultaneous management (i.e., change, addition and removal) of a plurality of data via a unified man machine communication (MMC). The method includes steps such as requesting, by the unified MMC, changing, adding, removing and display operations of data contained in either a single tuple data list or data contained in a plurality of tuple data lists, reading data from a table that provides either the single tuple data list or the plurality of tuple data lists, and performing the changing, adding, removing and display operations of the data via the unified MMC.
    • 一种用于管理数字蜂窝系统的维护系统中的数据的方法,其通过统一的人机通信(MMC)提供多个数据的同时管理(即,改变,添加和移除)。 该方法包括诸如由统一的MMC请求改变,添加,删除和显示包含在单个元组数据列表中的数据或包含在多个元组数据列表中的数据的操作的步骤,从提供 单元组数据列表或多个元组数据列表,并且经由统一MMC执行数据的改变,添加,删除和显示操作。

    • A method for providing push-to-talk (PTT) so as to conference between a plurality of user equipments (UEs) serving as clients in a mobile communication network including a PTT over cellular (PoC) server, a conference server, and a mixer for mixing for the conference. The method comprises performing a request procedure for switching over to the conference during a PoC session between the UEs; performing a conference client invitation or participation procedure for opening a conference session through the conference server; and performing a procedure for releasing the conference session between the PoC server and the UEs. The method can switch over to a conference service during a PTT service without newly initializing the conference service after completing an old PoC session, and can also switch over to bidirectional communication between all or some of the participants during a PoC session which is using unidirectional communications.
    • 一种用于提供一键通(PTT)的方法,以便在包括基于蜂窝的PTT(PoC)服务器,会议服务器和混合器的移动通信网络中用作客户机的多个用户设备(UE)之间进行会议 用于混合会议。 该方法包括在UE之间的PoC会话期间执行切换到会议的请求过程; 执行会议客户邀请或通过会议服务器打开会议会话的参与过程; 并执行用于释放PoC服务器和UE之间的会议会话的过程。 该方法可以在PTT业务中切换到会议业务,而不需要在完成旧的PoC会话之后重新初始化会议业务,并且还可以在使用单向通信的PoC会话期间切换到全部或部分参与者之间的双向通信 。

    • A method and system are provided for servicing a full duplex call in Push-To-Talk over cellular (PoC) in a communication system including at least two or more calling/called terminals for receiving a Push-To-Talk (PTT) service and a mobile network for providing the PTT service to the calling/called terminals. The calling terminal generates a full-duplex mode request message and transmits the full-duplex mode request message to the mobile network. The mobile network transmits the full-duplex mode request message to a PoC server that provides a PoC service to the calling terminal. Upon receiving the full-duplex mode request message, a PoC server of the calling terminal sets the calling terminal to a full duplex mode, and transmits the full-duplex mode request message to a PoC server of the called terminal. The PoC server of the called terminal transmits the full-duplex mode request message to the called terminal, and performs a call between the calling terminal and the called terminal in the full duplex mode if the called terminal responds to the full-duplex mode request message.
    • 提供了一种方法和系统,用于在包括用于接收一键通(PTT)服务的至少两个或更多个呼叫/被叫终端的通信系统中通过蜂窝(Push-To-Talk over cellular)(PoC)进行全双工呼叫的服务,以及 用于向呼叫/被叫终端提供PTT服务的移动网络。 主叫终端生成全双工模式请求消息,并将全双工模式请求消息发送到移动网络。 移动网络将全双工模式请求消息发送到向呼叫终端提供PoC服务的PoC服务器。 在接收到全双工模式请求消息时,主叫终端的PoC服务器将主叫终端设置为全双工模式,并将全双工模式请求消息发送到被叫终端的PoC服务器。 被叫终端的PoC服务器向被叫终端发送全双工模式请求消息,如果被叫终端响应全双工模式请求消息,则以全双工模式在主叫终端和被叫终端之间进行呼叫 。
