  • Patent number: 9049688
    Abstract: A device establishes a first communication session with an endpoint and is configured to perform the first session via one of two different call configurations. In response to unplanned termination of the first session, the device identifies a specific call terminating condition and determines when the call terminating condition is within a first subset of call terminating conditions. Then, in response, the device: creates a record of the first session, including information identifying the established call configuration; and activates a timer associated with the record. The device then autonomously accepts a request to establish a second communication session from an endpoint and implements the same call configuration for the second session, in response to the request (a) being received before expiration of the timer and (b) establishing the second session between the communication device and the same endpoint. With a Push-to-Talk call, the established call configuration is full duplex mode.

  • Patent number: 8195250
    Abstract: A multi-mode communication device (100) uses a first wireless modem (118) and a second wireless modem (120) which operates independently to facilitate communication over different air interfaces. Both modems are powered by a common battery (105). When the first wireless modem engages in a communication activity, the second wireless modem's maximum operating power level is reduced. When the first wireless modem ceases communication activity, the second wireless modems full operating power range is restored.

  • Patent number: 8059702
    Abstract: Within a communication device, a method of managing a plurality of modems can include determining a first measure of transmission power for a first modem (710), wherein the first measure of transmission power is a running total of transmission power for the first modem over a predetermined time period, and determining a second measure of transmission power for a second modem (715), wherein the second measure of transmission power is a running total of transmission power for the second modem over the predetermined time period. If a sum of the first measure of transmission power and the second measure of transmission power exceeds a threshold during the predetermined time period, at least one predetermined action can be performed (725, 730).

  • Patent number: 7937102
    Abstract: A multi-camp mobile communication device (100) includes a first radio modem (102) and a second radio modem (104). Each modem is designed to communicate with a respective communication system (110, 112). Upon engaging in an interconnect call (204) over the first modem with the first communication system, the multi-camp mobile communication device receives a dispatch call at the second modem (206) from the second communication system. The multi-camp mobile communication device replies to the dispatch call with a pre-recorded message (208). The dispatch calling party may respond to the pre-recorded message with a voice message that is recorded by the multi-camp mobile communication device (210, 212).

  • Publication number: 20080161050
    Abstract: A wireless communication device performs a method for automatically configuring itself to operate in a wireless communication system managed by a system controller. The wireless device includes an internal memory device containing a first memory identifier associated with a first removable memory device and a first user identifier associated with a user of the wireless device. In one embodiment, the wireless device compares the first memory identifier with a second memory identifier stored in a removable memory device coupled to the wireless device, and transmits a registration message including the second memory identifier to the system controller if the first memory identifier is different than the second memory identifier. The wireless device receives a registration confirmation message including a second user identifier associated with an expected user, and stores the second memory identifier in the internal memory device if the second user identifier matches the first user identifier.

  • Patent number: 6002948
    Abstract: A radio communication system (100) includes equipment (112) that manages communication initiated at a subscriber unit (122) and targeted at another subscriber unit (124). At the initiating subscriber unit, a communication mode is selected (410) from among multiple communication modes supported by the target subscriber unit. A mode independent identifier is obtained (420) for the target subscriber unit, and transmitted (430) to the system equipment along with the selected communication mode. The system equipment uses information based on the mode independent identifier to access (510, 520) the target subscriber unit. The system equipment then operates to enable (530, 540) the communication mode at the target subscriber unit, and to establish (550) communication between the initiating and target subscriber units.

  • Patent number: 5949774
    Abstract: A subscriber unit handles incoming calls routed through an old server site while in the process of switching site affiliation to a new server site (500). The subscriber unit initiates the switching of site affiliation (510), and during the process, alternates between receiving communication from the new server site (520) and receiving communication from the old server site to monitor for an incoming call (530). When an incoming call routed through the old server site is detected (540), the subscriber unit aborts or suspends the switching process and accepts the incoming call through the old server site (551, 552).

  • Patent number: 5937351
    Abstract: A mobile station (100) maintains a preferred bandmap (106) and a fixed bandmap (104). Upon powering up the mobile station, the mobile station begins scanning frequencies listed in the preferred bandmap. The strength of each detected carrier signal is measured, and the mobile station connect to the serving cell having the strongest carrier signal. The preferred bandmap is maintained by placing the frequency of the most recently connected serving cell at the head of the list, and moving other frequencies down the list as other are added or rotated to the top of the list.

  • Patent number: 5561852
    Abstract: A portable radio (104) initiates a communication link using a synchronous protocol format. A base station (102) generates a synchronization pattern (200) which includes a marker. The marker (202) includes a generic code that invites portables to make link requests. The portable radio (104) synchronizes to the marker (202) and recognizes the generic code that indicates base availability. The portable radio (104) sends a link request in response to the generic code to initiate the communication link, and the base station (102) grants a link in order to establish the communication link.
