    • A radio communication system (200) employs a method (400) and system (200) for establishing a communication between communication units (212-217) using geographically distributed packet duplicators (203-205). The communication system (200) includes a system controller (201), a plurality of packet duplicators (203-205), a plurality of base sites (207-210), and a plurality of communication units (212-217). The packet duplicators (203-205), which provide interconnectivity between the base sites (207-210), are distributed throughout geographic regions (233-234) of the system (200). When the system controller (201) receives a request to communicate from one communication unit (e.g., 212) in a group of communication units (e.g., 212-215), the system controller (201) selects a packet duplicator (e.g., 203) serving a geographic region (e.g., 233) containing at least one communication unit in the group and uses the selected packet duplicator (203) to establish the group communication.
    • 无线电通信系统(200)采用方法(400)和系统(200),用于使用地理上分布的分组复制器(203-205)在通信单元(212-217)之间建立通信。 通信系统(200)包括系统控制器(201),多个分组复制器(203-205),多个基站(207-210)和多个通信单元(212-217)。 在基站(207-210)之间提供互连的分组复制器(203-205)分布在系统(200)的整个地理区域(233-234)中。 当系统控制器(201)从一组通信单元(例如212-215)中接收到来自一个通信单元(例如212)的通信请求时,系统控制器(201)选择分组复制器(例如203) 服务于在该组中包含至少一个通信单元的地理区域(例如,233),并使用所选择的分组复制器(203)建立组通信。

    • The present invention encompasses a method of providing communication service to members of a talkgroup in a radio communication system (100). A typical system (100) includes a plurality of communication units (116-122), a plurality of communication sites (106-112), and a central controller (114) that communication resources among the communication units (116-122). Upon receipt of a request for a talkgroup call from a communication unit, the central controller (114) grants the talkgroup call request for the first talkgroup. When the central controller (114) receives, during the first call, a talkgroup call request for the same talkgroup, the controller (114) agglomerates the two concurrent talkgroup calls, thereby providing communication service to all members of the talkgroup using a single communication resource.
    • 本发明包括向无线电通信系统(100)中的通话组的成员提供通信服务的方法。 典型的系统(100)包括在通信单元(116-122)之间通信资源的多个通信单元(116-122),多个通信站点(106-112)和中央控制器(114)。 在从通信单元接收到对话组呼叫的请求时,中央控制器(114)授予第一通话组的通话组呼叫请求。 当中央控制器(114)在第一次呼叫期间接收到同一谈话组的通话组呼叫请求时,控制器(114)聚集两个并发谈话组呼叫,从而使用单个通信资源向通话组的所有成员提供通信服务 。

    • A multi-site communication system (100) includes a plurality of communication units ( 112-117), a central controller (101) for coupling a plurality of communication sites (106-108), and a site controller (103) corresponding to one of the communication sites (106). Communication access between two or more communication units (112-117) can be enhanced by a method (200, 300) including the steps of receiving (201) a request for a first communication, and directing (211) the appropriate site controller to re-submit the request. By so doing, the site controller (103) can request (314) the central controller (101) to establish a realizable communication between two communication units in the system (113, 114).
