    • A print server and method for forwarding printing data in a network are provided. The print server receives an IP address of a printer and a uniform resource identifier of printing data from a mobile station. The print server determines which printer corresponds to the IP address and forwards the printing data to the printer for printing, thereby allowing a mobile station to print data in remote locations. The mobile station does not have to format the printing data or transmit the formatted printing data, thereby reducing the burden on the operating system and the storage space of the mobile station.
    • 提供了一种用于在网络中转发打印数据的打印服务器和方法。 打印服务器从移动台接收打印机的IP地址和打印数据的统一资源标识符。 打印服务器确定哪个打印机对应于IP地址,并将打印数据转发到打印机进行打印,从而允许移动台在远程位置打印数据。 移动台不必格式化打印数据或发送格式化的打印数据,从而减轻了操作系统和移动台的存储空间的负担。

    • An apparatus, method and computer-readable medium for controlling dispatch voice communications between fleets in a network are provided. The apparatus includes a multi-fleet dispatch console configured to receive a request for a dispatch group call including dispatch stations in a plurality of fleets and to establish the dispatch group call based upon the request. The multi-fleet dispatch console has a higher priority than any other dispatch console in the network. According to the method, the multi-fleet dispatch console may also determine whether a requestor of the dispatch group call is authorized to establish the requested dispatch group call and output an authorization denial message, if the requestor is not authorized to establish the dispatch group call. Additionally, the multi-fleet dispatch console may drop unavailable dispatch stations from existing group calls, if a priority of the request exceeds a priority of the existing group calls.
    • 提供了一种用于控制网络中的队列之间的调度语音通信的装置,方法和计算机可读介质。 该装置包括:多车队调度台,被配置为接收对包括多个车队中的调度站的调度组呼叫的请求,并且基于该请求建立调度组呼叫。 多队列调度控制台的优先级高于网络中的任何其他调度控制台。 根据该方法,如果请求方未被授权建立调度组呼叫,则多机群调度控制台还可以确定调度组呼叫的请求者是否被授权建立所请求的分派组呼叫并输出授权拒绝消息 。 此外,如果请求的优先级超过现有组呼叫的优先级,则多机群调度控制台可能会将不可用的调度站从现有组呼中丢弃。

    • A method and system for establishing group multicast communication, such as PoC multicast communication. Multiple terminals will join a PoC multicast group automatically at some point before the underlying PoC session is being initiated and thus before there is any PoC content for a PoC server to multicast to the group members. Further, this joining process will occur without the PoC multicast channel being listed in the terminals' multicast channel listings. Thereafter, when one of the terminals opts to initiate the PoC session and thus signals to the PoC server, the server will cause the participating terminals to tune to the associated PoC multicast channel for the PoC multicast group that the terminals had already joined. The invention thereby helps to effectively randomize the timing of join-signaling by the various terminals and thus helps to conserve network resources.
    • 一种建立组播组播通信的方法和系统,如PoC组播通信。 多个终端将在基础PoC会话启动之前的某个时间点自动加入PoC组播组,因此在PoC服务器有PoC内容多播到组成员之前。 此外,如果没有在终端的多播信道列表中列出PoC多播信道,则该加入处理将发生。 此后,当其中一个终端选择启动PoC会话并且因此向PoC服务器发信号时,服务器将使参与终端调谐到终端已经加入的PoC组播组的相关PoC组播信道。 因此,本发明有助于有效地随机地将各种终端的加入信令的定时随机化,从而有助于节省网络资源。
