Abstract: A method for managing an attempted connection between a home base station (HBS) and a device not registered with the HBS is provided. The method includes transferring the connection when the attempted connection can be transferred to a traditional base station. When the attempted connection cannot be transferred to a traditional base station, it is determined whether a portion of the resources of the HBS can be used by the device not registered with the HBS. When a portion of the resources can be used, the portion is used. When a portion of the resources cannot be used, the attempted connection is not completed.

Abstract: A code division multiple access telecommunications network including an underlay base station in a private premises and a plurality of overlay macro base stations. The underlay base station includes a GPS receiver and a mobile unit receiver. The underlay base station uses its geographic location to obtain information identifying macro base stations within a preselected distance of the underlay base station. It uses the mobile receiver to measure pilot signal strength of the macro base stations. It generates a neighbor list of the identified macro base stations ranked according to pilot signal strength.

Abstract: A method for allocating a pseudorandom noise identifier (PN) to a home base station (HBS) is provided. The method includes determining the location of the HBS, determining the PNs in use adjacent to the HBS, and using the location of the HBS and the PNs in use to select a PN for the HBS.

Abstract: A small office/home office base transceiver station (SOHO BTS) server capable of managing interference by correlating pilot strength measurements sent by mobile devices and directing the attenuation settings for each transmit path. An array of antennas coupled to an array of transmit paths are selectively activated one at a time. When a transmit path is activated, the SOHO BTS server sets the associated variable attenuator to its maximum level. The SOHO BTS server detects whether a radio environment report or and a pilot strength measurement message (PSMM) containing information about a mobile station's pilot strength is present. When the pilot strength is greater than a predetermined value, the SOHO BTS server increases the setting on the attenuator. Otherwise, the SOHO BTS server decreases the attenuator setting until such pilot strength information is available or if the lowest attenuator setting has been set. The other transmit paths are also tested accordingly.

Abstract: A base station for use within a structure is provided. The base station includes an apparatus to automatically set an operating carrier power level to be effective within the structure and in a limited area surrounding the structure to promote reducing interference with mobile units outside the limited area. The base station also includes an apparatus to automatically set beacon channel power to provide service substantially within the structure.

Abstract: A system and method for dynamic threshold determination. The system and method of operating a base station. A base station is configured to transmit a first message to a subscriber station. The first message including a first threshold for use in measuring against the serving frequency strength and a second threshold for determining one or more target base stations. The mobile station responds with messages listing zero or more target base stations. Further, the base station is configured to dynamically adjust a value of at least one of the first threshold parameter and second threshold parameter in response to a call event.

The underlay base station includes a GPS receiver and a mobile unit receiver. The underlay base station uses its geographic location to obtain information identifying base stations within a preselected distance of the underlay base station. It uses the mobile receiver to measure signal strength of the base stations. It automatically selects as an operating frequency a channel dedicated to underlay stations or an unused channel allocated for macro base stations or a macro base station frequency which results in minimum interference. The mobile unit receiver may be used to identify the frequency with lowest signal level at the underlay station.

Abstract: A method for reducing a failure of a handoff to a home base station (HBS) is provided. The method includes a user device promoting initiating a handoff request. Responsive to receiving the handoff request from the user device, a mobile switching center (MSC) requests a hub HBS for the user device to sense whether the user device is in range to communicate with the hub HBS. The MSC completes the handoff when the hub HBS senses that the user device is in range and prevents the handoff when the hub HBS does not sense that the user device is in range.
