摘要： A method and apparatus are provided for allocating radio frequency carriers in a radio service area having a plurality of radio frequency TDMA carriers and FDMA carriers. The method includes the steps of receiving a call, when the received call is a FDMA call and a FDMA carrier is not available for the FDMA call, then preempting a pre-existing call on a TDMA carrier of the plurality of radio frequency TDMA carriers for the FDMA call and when the received call is a TDMA call and a TDMA slot is not available for the TDMA call, then preempting a pre-existing FDMA call on a TDMA capable carrier of the plurality of radio frequency TDMA carriers for the TDMA call.

摘要： A system and method for dynamically altering detection criterion value at a receiving device based on the portion of a call signal being received. A receiving device is configured to extract a first call signal portion from the call signal, and compare the first call signal portion to a plurality of call information portions, wherein each call information portion has a detection criterion value. If the first call signal portion matches one of the call information portions, the receiving device adjusts the detection criterion value for at least one of the plurality of call information portions, extracts a second call signal portion from the call signal, and compares the second call signal portion to the plurality of information portions.

摘要： A device receives a communication request for a time division multiple access (TDMA) communication. Upon receipt of the communication request, the device identifies a first communication channel that currently has at least one available TDMA slot and that is currently supporting a greatest number of active TDMA communications amongst a plurality of communication channels. Once the device identifies the first communication channel, the device allocates a first available TDMA slot for the TDMA communication on the first communication channel.

摘要： A method of key distribution includes generating, by a first system device (101), key material and forwarding the key material from the first system device (101) to a second system device (107). It is determined whether a mobile station (401), for which the key material is directed, is active on the system. When the mobile station is active, the key material is forwarded to a base station (115) where the mobile station (401) is active, and the base station (115) forwards the key material to the mobile station (401).

摘要： Systems and methods for implementing dispatch calls using IP multicasting protocols are disclosed. The methods include utilizing a payload multicast group address for distributing payload, and utilizing a control multicast group address for distributing control messages to members of the talkgroup in a single-zone (FIG. 1). A zone controller 116 dynamically identifies payload and control multicast group addresses and sends them to participating sites 102, 104. The participating sites 102, 104 issue Join commands to associated network devices 108, 110 to receive payload and control messages addressed to the respective payload and control multicast group addresses. There is further disclosed a system and method for implementing dispatch calls for members in multiple zones (FIG. 6). Zone controllers 630, 632 separately identify control multicast group addresses and send them to affiliating devices in their respective zones. A controlling zone controller 630 dynamically identifies a payload multicast group address that is used by participating devices in both zones. The participating sites 606, 616 issue Join commands to associated network devices 610, 622 to receive payload messages addressed to the payload multicast group address and control messages addressed to their control multicast group address.

摘要： A method of handling busy calls, performed by a controlling entity (ZC1) in a multiple-zone system, includes the steps of issuing (201) a request to participate in a call to one or more participating zones (101, 103, and 105) and concluding (203) that at least one zone of the participating zones (101, 103, and 105) is unable to grant the call, thereby resulting in a busy status for the call. The controlling entity (ZC1) informs the participating zones (101, 103 and 105) of the busy status. A resource available notification is received (209) from a first zone, and the controlling entity (ZC1) determines (211) if a predetermined number of the participating zones (101, 103, and 105) have indicated ability to grant the call. When at least one zone of the one or more participating zones has not indicated ability to grant the call, the controlling entity (ZC1) issues (213) a still busy notification to the first zone, which still busy notification indicates that the call still has a busy status.
摘要翻译：一种处理由多区域系统中的控制实体（ZC1）执行的忙碌呼叫的方法，包括以下步骤：发出（201）参与对一个或多个参与区域（101,103和105）的呼叫的请求并且结束（203）参与区域（101,103和105）的至少一个区域不能授予呼叫，从而导致呼叫的忙状态。控制实体（ZC1）通知参与区（101,103和105）忙碌状态。从第一区域接收资源可用通知（209），并且控制实体（ZC1）确定（211）预定数量的参与区域（101,103和105）是否已经指示了授权呼叫的能力。当一个或多个参与区域的至少一个区域没有指示授权呼叫的能力时，控制实体（ZC1）发出（213）仍然忙碌的通知给第一区域，仍然忙碌通知指示呼叫仍然具有忙碌状态。

摘要： In a communication system, the following describes a method for the communication system to more efficiently process control information when the control channel is temporarily used as a voice channel. When a communication unit has control information to transmit to the communication resource allocator, it determines whether the monitored voice channel is busy. When the monitored voice channel is not busy, the communication unit transmits the control information to the communication resource allocator on the monitored voice channel. Regardless of whether the monitored voice channel is busy or not, the communication resource allocator transmits recommended channel parameters on the monitored channel wherein the recommended channel parameters comprises at least one recommended channel. When the monitored voice channel is busy, the communication unit decodes the recommended channel parameters to ascertain the at least one recommended channel. Having done this, the communication unit determines whether the at least one recommended channel is usable, and when the recommended channel is usable, the communication unit transmits its control information on that channel to the communication resource allocator.

摘要： In a trunked communication system with at least two communication sites, a call hand-off mid-call may occur when a mobile radio (109) moves from the coverage area of one site to the coverage area of another site. This second site may not have any communication resources available for this hand-off, and the radio (109) is issued a busy message. With user selectable site switching, the user may enter into the radio (221) the desire to return to the previous site, and the radio moves to the previous channel to continue (229) receiving the call.
