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. 8 ). Zone controllers (830, 832) separately identify control multicast group addresses and send them to affiliating devices in their respective zones. A controlling zone controller (830) dynamically identifies a payload multicast group address that is used by participating devices in both zones. The participating sites (806, 816) issue Join commands to associated network devices (810, 822) to receive payload messages addressed to the payload multicast group address and control messages addressed to their control multicast group address.

摘要： In a communication system network, the central controller may more efficient respond to group regrouping requests in the following manner. Once a console generates a dynamic group regrouping request which requests the regrouping of a set of communication groups into a super group, the central controller determines, for each communication system, whether at least one of the set of communication groups is registered in that communication system. When at least one of the set of communication groups is registered in the communication system, the central controller groups the at least one of the set of communication groups into a local super communication group. Having done this, the central controller then generates super communication group information and transmits it to the communication systems but only that portion that pertains to the local super communication group.

摘要： A system and method for effectively and reliably terminating a voice call in any burst within a multi-burst superframe. A transmitting unit generates a termination burst upon detecting a dekey event. The termination burst includes a data synchronization pattern, a slot type field indicating an end of a call, and an information field surrounding the data synchronization pattern and the slot type field. The information field is encoded from a predetermined voice encoder frame unique to the termination burst. Once all buffered voice information is transmitted, the termination burst is transmitted prior to the end of the multi-burst superframe. A base station or other receiving unit monitors the incoming signal. Upon detecting the data synchronization pattern, the receiving unit decodes the slot type field and the information field. The receiving unit determines whether the decoded slot type field is indicative of the end of a call, and whether a specific portion of the decoded information field matches the predetermined voice encoder frame. If both are true, the receiving unit terminates the call.
