    • A first communication unit (101) transmits, to a central controller (105), a request for a group call. The central controller allocates a first inbound (11), a second inbound (12), and an outbound (O.sub.1) wireless communication resource for use in the group call. At the central controller, primary voice signals from the first communication unit, received via the first inbound wireless communication resource, are summed (109) with interrupt voice signals from a second communication unit (102), received via the second inbound wireless communication resource, to produce summed voice signals. The summed voice signals and a busy signal (108) are transmitted via the outbound wireless communication resource, thereby allowing the second communication unit to interrupt the group call. Additionally, the central controller can allocate a third inbound communication resource (13) for use with priority interrupt voice signals which can also be summed with the primary and interrupt voice signals.
    • 第一通信单元(101)向中央控制器(105)发送对群组呼叫的请求。 中央控制器分配在组呼中使用的第一入站(11),第二入站(12)和出站(O1)无线通信资源。 在中央控制器处,经由第一入站无线通信资源接收到的来自第一通信单元的主要语音信号通过经由第二入站无线通信资源接收的来自第二通信单元(102)的中断语音信号相加(109) 产生相加的语音信号。 通过出站无线通信资源发送相加的语音信号和忙信号(108),从而允许第二通信单元中断组呼。 此外,中央控制器可以分配第三入境通信资源(13),以便与也可以与主要和中断语音信号相加的优先中断语音信号使用。

    • While participating in a group call on a first wireless communication resource 114, senior members 104-107 of a communication group 108 can initiate a semi-private call. A central controller 110 allocates a second wireless communication resource 115 for the semi-private call. Furthermore, executive members 106-107 can initiate an executive call to be established on a third wireless communication resource 116. Executive members can participate in the executive call, the semi-private call, and the group call, whereas senior members can participate in the semi-private call and the group call. Junior members 101-103, normally allowed to participate only in the group call, can be selected by senior members to temporarily participate in the group call and the semi-private call.
    • 在参与第一无线通信资源114的组呼叫时,通信组108的高级成员104-107可以发起半私有呼叫。 中央控制器110为半私人呼叫分配第二无线通信资源115。 此外,执行成员106-107可以启动在第三无线通信资源116上建立的执行呼叫。执行成员可以参与执行呼叫,半私人呼叫和组呼,而高级成员可以参与 半私人电话和群组通话。 初级会员101-103,通常只允许参加集团电话,可由高级会员选择,暂时参加集团电话和半私人电话。
