  • Apparatus, and associated method, for facilitating communication handovers in a bluetooth-public-access radio communication system
    Patent number: 6675015
    Abstract: Apparatus, and an associated method, for facilitating handover of communication in a BLUEPAC (Bluetooth public access) or other radio communication system. Address and timing information associated with potential target base stations is collected and broadcast to mobile devices during operation of the radio communication system. The information is utilized by the mobile device during handover procedures to facilitate efficient handover of communications to a selected target base. In a further implementation, a base station is provided with separate, dedicated transmitters in which a first set of dedicated transmitters is dedicated for setup operations with a mobile device during handover operation and another set of dedicated transmitters is dedicated for regular data communications.
