Abstract: A method (100) and system (10) for controlling ad-hoc membership in wireless networks to improve battery life includes determining (102) the capabilities of each of the members of a network and upon launching an application at a member, determining (104) a profile of members of the network required to support the application. A master device (12) can optionally disassociate (106) from the slave devices surveyed until an application is launched having a profile requiring a particular slave device. The method can further include associating (108) the members of the network in the profile and temporarily disassociating (110) a remaining group of members of the network. At another step (112), the method can also assign a higher priority to the members meeting the profile and assign a lower priority to the members that are temporarily disassociated and thereby reduce a maintenance cycle by probing the lower priority members less frequently.

Abstract: A communication device (110) that includes a wireless adapter (112) and a processor (114). The wireless adapter can communicate via a Bluetooth communications protocol. The processor can determine whether at least a second communication device (130) is identified in a device history list (120). In response to determining that the second communication device is identified in the device history list, the processor can automatically attempt to connect to the second communication device via the wireless adapter. In response to determining that the second communication device is not identified in the device history list, the processor can automatically initiate discoverable mode in the communication device. The processor also can generate a user notification in response to a detection of the second communication device. In addition, the processor can add the second communication device to the device history list in response to connecting to the second communication device.

Abstract: A mobile communication device (100) contains a local wireless controller (114) for operating with a remote audio processor (124). The remote audio processor is used for listening to and speaking with remote parties via the mobile communication device, and operates in a mode having a relatively long latency in communicating with the mobile communication device. Upon receiving a dispatch call (306), a baseband processor (108) of the mobile communication device notifies an application processor (110) with a high priority dispatch notification (122). The high priority dispatch notification causes an active link to be established between the mobile communication device and remote audio processor sooner than if were to occur with ordinary call processing.

Abstract: A global positioning system (GPS) receiver (100) for receiving signals from a plurality of GPS satellites has a plurality of antennas (102), a receiver (104) coupled to the plurality of antennas, and a processor (106) coupled to the receiver. The processor is programmed to collect (202) from the receiver information from each of the plurality of antennas corresponding to signals received from the plurality of GPS satellites, process (204) the information, identify (206) from the processed information an antenna from the plurality of antennas having a probability higher than the other antennas for accurately locating the GPS receiver, locate (210) the GPS receiver according to signals from the plurality of GPS satellites received by the antenna if (208) the probability is greater than a predetermined threshold.

Abstract: A method (100) and system (11) of dynamic power savings for a shorter range wireless connection based on service conditions for a longer range wireless connection can include the monitoring (102) a latency requirement for the longer range wireless connection based on service conditions and dynamically modifying (104) a reconnect time for the shorter range wireless connection with a change in the latency requirement for the longer range wireless connection based on change in service conditions. The latency requirement for the longer range wireless connection can be based on changes in communication modes for the longer range wireless connection. The communication modes can be a dispatch audio mode, an interconnect audio mode, or an out of service mode for example. The step of dynamically modifying the reconnect time can optionally include adjusting (106) the reconnect time as service conditions change to meet a most critical timing to be encountered.
