  • Publication number: 20060211431
    Abstract: A system and method for determining the location of a base transceiver station (BTS) are provided. A personal BTS can determine its location using information transmitted by neighboring BTSs or from mobile station transmissions to neighboring BTSs. If the personal BTS cannot determine its location using information from neighboring BTSs or from mobile station transmissions, the personal BTS can contact a cellular network operator to request that a technician come out to verify the location.

  • Publication number: 20060056374
    Abstract: Systems and methods for Walsh code assignment are provided. In accordance with the disclosed exemplary embodiments, when a set of mobile communication units (MU) is in a control/hold state, instead of a base transceiver station (BTS) assigning Walsh codes for respective dedicated control channels (dcch) to the set of mobile communication units (MU) on a one-to-one basis, the base transceiver station (BTS) circulates the Walsh codes among the set of mobile communication units (MU). Thus, at a given time, the base transceiver station (BTS) has assigned the available Walsh codes to only a subset of the mobile communication units (MU) in the control/hold state. Accordingly, this Walsh code assignment allows the system to support more mobile communication units (MU) in the control/hold state.
