摘要： A system and method for signaling and delivering group communication data, such as push-to-talk (PTT) setup data, to a dormant wireless telecommunication device across a control channel on a wireless communication network. Each wireless telecommunication device is able to direct a single group communication stream to a designated target group of other wireless telecommunication devices, and the wireless telecommunication device has a dormant state in which the wireless telecommunication devices bridges a control channel with a communication server and an active state in which the wireless telecommunication device bridges a dedicated communication channel with the communication server. The wireless telecommunication device receives group communication setup data though a control channel for incoming group communications, and such delivery occurring without fully bridging a dedicated communication channel to that wireless telecommunication device.

摘要： A wireless push-to-talk (PTT) communication system 100 assigns a special dispatch priority to for emergency communications to and from police, fire dept. or communications to other emergency personnel. A communication which has been assigned dispatch priority takes precedence over all other non-dispatch priority communications for initially completing the call and maintaining the communications links. An indication of dispatch priority in a 1xEV-DO system may be achieved by setting a bit in the RequestReason field 604 of the ConnectionRequest message 602.
摘要翻译： 无线一键通（PTT）通信系统100将特别的调度优先级分配给来自警察，消防部门的紧急通信。 或与其他应急人员沟通。 已经分配了调度优先级的通信优先于所有其他非调度优先级通信，用于初始完成呼叫并维护通信链路。 可以通过在ConnectionRequest消息602的RequestReason字段604中设置一个位来实现1xEV-DO系统中的调度优先级的指示。

摘要： Apparatus and method for reducing latency in push-to-talk communications in a wireless communication network. Time sensitive push-to-talk (PTT) related messages are identified in a specially designated header, so they can be handled differently by radio mobile devices. These messages with the special designated header are transmitted through signaling channels from a radio transmission unit to a mobile device, as opposed to being transmitted as dedicated channel traffic.

摘要： A system and method for minimizing latency for direct group communications, such as push-to-talk (PTT) calls, among a group of wireless telecommunication devices on a wireless telecommunication network. The wireless telecommunication device selectively requests and then receives an open dedicated broadcast channel for an outgoing communication, which can include a group communication stream to a communication server that receives and creates a group communication to all wireless telecommunication devices of the designated group. The wireless telecommunication device selectively receives a broadcast channel based upon a predetermined probability, and assigns a greater probability of receiving an open broadcast channel for requests to transmit group communication streams than for requests to open a broadcast channel that are not for a group communication.

摘要： In an embodiment, an access terminal sends a request for a level of Quality of Service (QoS) resources to an access network, the QoS resource request associated with a call attempt by the access terminal. The access terminal proceeds with call set-up for the call attempt irrespective of whether the access network grants the QoS resource request. Alternatively, the access terminal waits for an extended period of time before the call attempt is permitted to fail. In a further example, in the event of call failure, the access terminal can refrain from informing a user thereof of the call failure. In another embodiment, the access network can respond to the QoS resource request with an allocation of a lower level QoS resources than requested if the requested QoS resources are not available. The access terminal can likewise be permitted to participate in the call with the lower level QoS resources.
摘要翻译： 在一个实施例中，接入终端向接入网发送对服务质量（QoS）等级的请求，所述QoS资源请求与接入终端的呼叫尝试相关联。 无论接入网络是否授予QoS资源请求，接入终端进行用于呼叫尝试的呼叫建立。 或者，接入终端在允许呼叫尝试失败之前等待较长的时间段。 在另一示例中，在呼叫失败的情况下，接入终端可以避免向其用户通知呼叫失败。 在另一个实施例中，如果所请求的QoS资源不可用，则接入网络可以以比所请求的低的QoS资源的分配来响应QoS资源请求。 同样可以允许接入终端参与具有较低级QoS资源的呼叫。
