  • Patent number: 8086279
    Abstract: Handover of call serviced by modular ear-piece/microphone between servicing base portions is presented. A wireless headset includes wireless interface(s), earpiece, a microphone, processing module, and a user interface. The wireless interface(s) wirelessly couples the wireless headset to a base unit via a wireless personal area network (WPAN). The earpiece renders inbound portions of the service calls audible while the microphone is operable to produce the outbound portion of the call. Both the earpiece and microphone are communicatively coupled to the wireless interface(s). The processing module also coupled to the wireless interface(s) allows the wireless headset to initiate call functions between the wireless headset and a servicing network made available through the base unit, service a call and call control functions, and anchor the call to the wireless headset.

  • Patent number: 8041404
    Abstract: A system and method for managing messaging in a mobile communication system (e.g., having power-save capability) in a multiple network environment. For example, the mobile communication system may operate in a power-save mode (e.g., a mode in which the mobile communication system does not communicate messages). The mobile communication system may exit the power-save mode. After exiting from the power-save mode, the mobile communication system may determine to establish communication with a second system (e.g., a message server) over a second communication path instead of a first communication path. Communication with the second system may be established over the second communication path, and message-related information may be communicated between the mobile communication system and the second system. Such message-related information may, for example, comprise message information, information regarding message availability, or information regarding the communication of message information.

  • Patent number: 8040788
    Abstract: A system and method for allocating communication resources in a multi-transceiver communication system, where multiple transmitters transmit respective signals to a generally similar area. Various aspects of the present invention may comprise allocating frequency and time bandwidth for communication with a second communication system. A first portion of a plurality of transmitters may be allocated for communication with the second communication system utilizing the allocated frequency and time bandwidth. A second portion of the plurality of transmitters may be allocated for a purpose other than utilizing the allocated frequency and time bandwidth to communicate with the second communication system. For example, the second portion of the plurality of transmitters may be blocked from transmitting or allocated for communication with a third communication system utilizing the allocated frequency and time bandwidth.

  • Publication number: 20110202576
    Abstract: A mobile device communicates position samples of one or more reference position with respect to one or more other communication device such as access points to a location server communicatively coupled to a reference database. The location server determines whether to utilize the one or more reference position in the reference position database based on the communicated samples. The mobile device scans the position samples, which indicate position information of the one or more other communication device and/or whether the position information is reliable for use. The scanned position samples are accumulated and transmitted to the location server. The location server updates records for the one or more reference positions with respect to the one or more other communication device in the reference position database based on the accumulated position samples received. The updated records are utilized to determine a fast position fix for the position device.
