Radio access point location verification using GPS location and radio environment data

摘要

Techniques are provided to perform location verification of a radio access point device such as femtocell. The radio access point device is configured to receive signals from global positioning system (GPS) satellite transmitters to produce GPS location data representing a GPS location of the radio access point device. The radio access point device is also configured to receive wireless signals at one or more specified channels and to generate radio environment data representing characteristics of received wireless signals. A comparison is made between the GPS location data and reference GPS location data for an expected location of the radio access point device. When the GPS location data substantially matches the reference GPS location data, operations of the radio access point device are enabled and the radio environment data is stored to be used as reference radio environment data for purposes of subsequent location verification of the radio access point device.

1. A method comprising:
at a radio access point device:
receiving signals from global positioning system (GPS) satellite transmitters to produce GPS location data representing a GPS location of the radio access point device;receiving wireless signals in one or more specified channels and generating radio environment data representing characteristics of received wireless signals in the one or more channels;comparing the GPS location data with reference GPS location data for an expected location of the radio access point device;verifying that the radio access point device is at an acceptable location when results of the comparing indicate that the GPS location data substantially matches the reference GPS location data; when the GPS location data substantially matches the reference GPS location data:
enabling service of the radio access point device;storing the radio environment data to be used as reference radio environment data for purposes of subsequent comparison to subsequently generated radio environment data for location verification of the radio access point device, wherein the radio environment data is not used to determine a location of the radio access point; and when the GPS location data does not substantially match the reference GPS location data:
disabling service of the radio access point device, andwherein when the radio access point device is subsequently rebooted, the radio access point device subsequently boots up with service disabled, further comprising receiving additional wireless signals to generate additional radio environment data, comparing the additional radio environment data with the reference radio environment data, and re-enabling service of the radio access point device when the additional radio environment data substantially matches the reference radio environment data.
