    • A method for performing a push to talk (PTT) communication service in a portable terminal. The method comprises entering a PTT communication mode and providing a PTT application, when a function key and an abbreviated number key for performing the PTT communication service are input to the portable terminal and performing the PTT communication service based on subscriber information of the PTT communication service corresponding to the input abbreviated numbers. Several steps of key inputs and menu selections can be removed because, the method requires only a few abbreviated number for reflecting all the necessary steps stored previously in the memory such that it can provide an improved convenience and simplicity of the operation for the PTT communication service to the users.
    • 一种用于在便携式终端中执行一键通(PTT)通信服务的方法。 该方法包括:当用于执行PTT通信服务的功能键和缩写数字键被输入到便携式终端并且基于PTT通信服务的用户信息执行PTT通信服务时,输入PTT通信模式并提供PTT应用 对应于输入的缩写数字。 可以删除关键输入和菜单选择的几个步骤,因为该方法仅需要几个缩写号码来反映先前存储在存储器中的所有必要步骤,从而可以提供PTT通信服务的操作的改进的便利性和简单性 给用户

    • A method for communicating using a Push To Talk (PTT) call traffic scheme in a mobile communication system. The method comprises the steps of selecting at least one subscriber with whom a calling user wants to communicate through the PTT call traffic scheme, determining if a Push To Data (PTD) is to be transmitted when sending a PTT call request, and selecting the PTD to be transmitted if the PTD is to be transmitted, in a calling mobile communication terminal, transmitting the PTD and the PTT call request message from the calling mobile communication terminal to at least one called mobile communication terminal of the selected subscriber via a PTT server, outputting contents of the PTD and indicating reception of the PTT call request to the selected subscriber by the called mobile communication terminal, when receiving the PTD and the PTT call request; and transmitting a PTT call request acceptance message to the PTT server to allow the calling and the called mobile communication terminals to communicate with each other through the PTT call traffic if the at least one called mobile communication terminal inputs the PTT call request acceptance key by the subscriber's operation.
    • 一种用于在移动通信系统中使用一键通(PTT)呼叫业务方案进行通信的方法。 该方法包括以下步骤:通过PTT呼叫业务方案选择主叫用户与之通信的至少一个用户,确定在发送PTT呼叫请求时是否发送推送数据(PTD),并选择PTD 在呼叫移动通信终端中通过PTT服务器将PTD和PTT呼叫请求消息从呼叫移动通信终端发送到所选用户的至少一个被叫移动通信终端, 当接收到PTD和PTT呼叫请求时,由被叫移动通信终端输出PTD的内容并指示接收到PTT呼叫请求给所选择的用户; 以及如果所述至少一个被叫移动通信终端将所述PTT呼叫请求接受密钥输入到所述PTT呼叫请求接受密钥,则向所述PTT服务器发送PTT呼叫请求接受消息,以允许呼叫和被叫移动通信终端通过所述PTT呼叫业务相互通信 用户的操作。
