摘要： An incident commander computing device dynamically reconfigures subscriber unit usage of radio access networks by first identifying, based at least on a type of incident occurring within a particular geographic area, a first incident response group having a first higher priority for responding to the incident and a second incident response group having a second lower priority for responding to the incident, then identifying a first higher priority radio access network having a sufficient coverage level across the particular geographic area and a second lower priority radio access network having a sufficient coverage level across the particular geographic area, and finally assigning the first incident response group to the first higher priority radio access network and assigning the second incident response group to the second lower priority radio access network.

摘要： A method for Fixed Network Equipment (FNE) to control the three of four and one of four slow associated control channel (SACCH) pattern on an Association of Public-Safety Communications Officials (APCO) Project 25 (P25) trunked voice channel is provided. Knowledge of this pattern by both the FNE and radio allows for unique information to be signaled in each type of SACCH. According to some embodiments, an operation enables controlling the floor (inbound) while there is an independent outbound (floor) (e.g. Console takeover). The provided operation also allows each radio to differentiate inbound floor control signaling from outbound caller identification (ID). Having the infrastructure control the inbound SACCH pattern and communicate this to all radios, makes the correct detection of the transmitted pattern from the radio more reliable.

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 call information portions.

摘要： A method for providing a mobile device in a packet data network access to a channelized network is disclosed. At a gateway between the two networks, a first channelized network message that is encapsulated in a first IP data packet from the packet data network is received. The first channelized network message is retrieved and reformatted for sending over the channelized network. The gateway then receives a second channelized network message from the channelized network. An identifier of a mobile device associated with the second channelized network message is retrieved and an IP address for the identified mobile device is determined. Then, the gateway encapsulates the second channelized network message into a second IP data packet and sends the encapsulated second channelized network message to the identified mobile device in the packet data network.

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 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.
摘要翻译：一种用于在多突发超帧内的任何突发中有效且可靠地终止语音呼叫的系统和方法。一个发送单元在检测到一个dekey事件时产生一个终止脉冲串。终止脉冲串包括数据同步模式，指示呼叫结束的时隙类型字段以及围绕数据同步模式和时隙类型字段的信息字段。该信息字段由终止脉冲串唯一的预定语音编码器帧编码。一旦发送了所有缓冲的语音信息，则在多突发超帧结束之前发送终止脉冲串。基站或其他接收单元监视输入信号。在检测到数据同步模式时，接收单元对时隙类型字段和信息字段进行解码。接收单元确定解码的时隙类型字段是否表示呼叫的结束，以及解码的信息字段的特定部分是否与预定语音编码器帧匹配。如果两者均为真，则接收单元终止呼叫。

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： From an unusable site, one or more communication units selects a usable site, thereby reducing missed communications. First, a manager determines (201, 401, 601) that a site is unusable for a predetermined set of communication unit(s). The predetermined set of communication units may include one or more individual communication units or communication units that are affiliated with a particular talkgroup at a particular time. A zone controller (104) identifies (205, 405, 605) any communication units from the set that are registered at the unusable site. The zone controller sends (207, 407, 607) a message to the identified units to assist them in leaving the site. The communication units search (303, 505, 709) the near sites for usability and register (307, 515, 713) at new usable sites. An algorithm is provided to stagger registration by communication units at usable sites.
