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： In a wireless communication system with an air interface comprising a plurality of bursts, a plurality of bursts is defined. Each burst comprises a field (300) embedded within the burst. The field is one of a synchronization field (300′) and a signaling field (300″). When the field is a synchronization field, a position of at least one subsequent burst comprising the signaling field is defined, and a position of at least one subsequent burst comprising the synchronization field is defined.

摘要： In a wireless communication system with an air interface comprised of a plurality of bursts, a communication device (102) receives a burst (200). The burst comprises payload (206, 208), a first indicator (202) and a second indicator (204). Upon receipt of the burst, the communication device determines a value of the first indicator to determine whether end-to-end encryption is applied to at least a portion of the payload, and determines a value of the second indicator to determine whether air interface encryption is applied to at least a portion of the payload.

摘要： A received synchronization pattern is compared against first and second known synchronization patterns. If the received pattern is of the first known pattern, the payload is processed as voice; and if the received pattern is of the second known pattern, the payload is processed as non-voice. In an alternative, the received pattern is compared against first and second known synchronization patterns. If the received pattern is of the first known pattern, a first operating mode is selected, and if the received pattern is of the second known pattern, a second operating mode is selected.

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.
