Abstract:
A selective call transceiver (20) in a messaging system (100) having a plurality of transmitters (90, 94, 99), comprises a receiver module (26), a transmitter module (22) coupled to the receiver module and a controller (28) coupled to the receiver module and the transmitter module for controlling the operation of the selective call transceiver. Additionally the selective call transceiver comprises a GPS receiver (24) for receiving GPS information and coupled to the controller, wherein the controller uses the GPS information to assist in the control of functions selected from the group consisting of transmitter power control, site selection switching, sub-zone selection switching, forward error correction, retry transmission decisions, Doppler frequency shifting, synchronization, and frequency scanning and selection.
Abstract:
A subscriber unit (122) acquires (604) communications with a first network (102) of a messaging system, the first network able to communicate at a first bandwidth. Thereafter, the subscriber unit determines (606) that it momentarily needs to communicate at a second bandwidth higher than the first bandwidth. In response, the subscriber unit reacquires (612) communications with a second network (115) different from the first network and able to communicate at the second bandwidth.
Abstract:
In an ad hoc wireless network having a plurality of members, a master, while communicating on a first communication channel, recognizes (202) a need for assistance in managing the network. In response to the need, the master negotiates (204) with a member of the ad hoc wireless network for the member to become a sub-master. The sub-master then assumes (206) management of a portion of the plurality of members. The sub-master and the portion then communicate (208) on a second communication channel negotiated with the master.
Abstract:
A user selects (402) a first communication device (122) from a plurality of terminal devices capable of supporting differing sets of communication features. The user then conveys (404) a user identity to the first communication device. The first communication device then conveys (406) the user identity and a device description describing the first communication device and the communication features supported by the first communication device to a bearer service (116) through which the first communication device communicates. The bearer service then conveys (408) the user identity and the device description, along with a bearer description describing characteristics of the bearer service, to a registry controller (112). Thereafter, the registry controller provides (418) communications to the user in accordance with the user identity, the device description, and the bearer description.
Abstract:
A first transceiver (122) detects (402) a need for desired information available from a network server (108). In response to detecting the need and before contacting the network server, the first transceiver attempts (412) to obtain the desired information from another transceiver of a plurality of wireless transceivers near the first transceiver, thereby potentially eliminating a necessity for the first transceiver to contact the network server to obtain the desired information.
Abstract:
A self configuring multiple element portable electronic device ( 100 ) and method is provided. The device comprises at least a first electronic element ( 104 ) and a second electronic element ( 106 ) and a joint ( 112 ) connecting the first electronic element and the second electronic element, with the joint allowing movement in more than one plane of the first electronic element in relation to the second electronic element, wherein the self configuring multiple element portable electronic device is capable of self configuring an operational mode based on a relative position of the first electronic element with respect to the second electronic element. The method comprises the steps of detecting a relative position of the first electronic element relative to the second electronic element, and selecting an operational mode of the device based on the relative position.

Abstract:
A table (328) is created (402) for mapping, for ones of a plurality of portable subscriber units (122), a plurality of message types to a corresponding plurality of locations. A message matching one of the plurality of message types is then received (404) by a controller (112), the message intended for a portable subscriber unit. In response, the controller and the portable subscriber unit cooperate to determine (406) the location of the portable subscriber unit. The controller sends (428) the message to the portable subscriber unit when the location matches one of the plurality of locations corresponding to the one of the plurality of message types.
