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.

Claims

1. A method for determining a location of a base station comprising the acts of:

assigning the base station to an initial base station controller;

determining the location of the base station using wireless communication signals monitored by the base station; and

determining a final serving base station controller for the base station based on the determined location of the base station,

wherein the base station is at a same location when the initial base station controller is assigned and the final serving base station controller is determined,

wherein the wireless communication signals comprise signals transmitted from base stations,

wherein when the base station cannot determine its location from information in the wireless communication signals transmitted from the base stations, the wireless communication signals further comprise signals transmitted by mobile stations, and the location of the base station is determined using information in the signals transmitted by the mobile stations, and

wherein signals transmitted by the mobile stations comprise location update messages which include a GPS time and location.

3. The method of claim 1, wherein the base station communicates with mobile stations using a code division multiple access (CDMA) scheme.

4. The method of claim 1, wherein when the location of the base station cannot be determined using the monitored wireless communication signals, the method comprises the act of:

transmitting a message to a cellular network operator requesting a technician to verify the location of the base station.

5. The method of claim 1, wherein the base station communicates with a cellular macro network over a consumer'"'"'s Internet connection.

2. A method for determining a location of a base station comprising the acts of:

determining that the location cannot be determined using received global positioning satellite (GPS) signals;

monitoring wireless communication signals; and

determining the location of the base station using the monitored wireless communication signals,

wherein the wireless communication signals comprise signals transmitted from base stations,

wherein when the base station cannot determine its location from information in the wireless communication signals transmitted from the base stations, the wireless communication signals further comprise signals transmitted by mobile stations, and the location of the base station is determined using information in the signals transmitted by the mobile stations, and

wherein signals transmitted by the mobile stations comprise location update messages which include a GPS time and location.

6. A method for determining a location of a base station comprising the acts of:

assigning the base station to an initial base station controller;

determining the location of the base station using wireless communication signals monitored by the base station, wherein the location is determined by triangulation using global positioning satellite (GPS) time and location information in the monitored wireless communication signals; and

determining a final serving base station controller for the base station based on the determined location of the base station, wherein the GPS time and location information is broadcast from at least three base stations,

wherein when the base station cannot determine its location from information in the wireless communication signals transmitted from the base stations, the wireless communication signals further comprise signals transmitted by mobile stations, and the location of the base station is determined using information in the signals transmitted by the mobile stations, and

wherein signals transmitted by the mobile stations comprise location update messages which include a GPS time and location.

8. The method of claim 6, wherein when the location of the base station cannot be determined using the monitored wireless communication signals, the method comprises the act of:

transmitting a message to a cellular network operator requesting a technician to verify the location of the base station.

9. The method of claim 6, wherein the base station communicates with a cellular macro network over a consumer'"'"'s Internet connection.

7. A method for determining a location of a base station comprising the acts of:

monitoring wireless communication signals transmitted by at least one other base station or at least one mobile station; and

determining the location of the base station using the monitored wireless communication signals, wherein the location is determined by triangulation using global positioning satellite (GPS) time and location information in the monitored wireless communication signals,

wherein when the base station cannot determine its location from information in wireless communication signals transmitted from base stations, the wireless communication signals further comprise signals transmitted by at least one mobile station and the signals transmitted by the at least one mobile station comprises location update messages which include the GPS time and the location.
