Radio access point device location verification based on wireless user device roaming history
First Claim
1. A method comprising:
- obtaining roaming history data of wireless user devices in a wireless cellular communication network with respect to base transceiver stations each configured to serve a corresponding coverage area at a fixed known location and with respect to radio access point devices each configured to serve a corresponding relatively smaller coverage area in the wireless cellular communication network and which radio access point devices are readily movable from one location to another location, the roaming history data comprising;
location update information comprising local area code information associated with location areas of the wireless user devices relative to the base transceiver stations in the network; and
measurement record information comprising indications of frequencies of signals received by the user devices; and
analyzing the local area code information in the location update information and frequency information in the measurement record information of the roaming history data to determine a time between updates of the location update information and the measurement record information; and
determining that a radio access point device is operating at a location other than its expected location when the determined time indicates that the updates of the location update information and the measurement record information would not be possible unless the radio access point is operating at the location other than its expected location.

Abstract
Techniques are provided to detect when a radio access point device in a wireless cellular communication network is operating at a location other than its expected location. Roaming history data is obtained for wireless user devices in a wireless cellular communication network with respect to base transceiver stations each configured to serve a corresponding coverage area at a fixed known location and with respect to radio access point devices each configured to serve a corresponding relatively smaller coverage area in the wireless cellular communication network than a macro base transceiver station. Radio access point devices are also readily movable from one location to another location. The roaming history data of wireless user devices is analyzed against expected locations of radio access point devices to determine when a radio access point device is operating at a location other than its expected location.

14. An apparatus comprising:
-
a network interface unit configured to enable communications over a network; a processor configured to be coupled to the network interface unit, the processor configured to; obtain roaming history data of wireless user devices in a wireless cellular communication network with respect to base transceiver stations each configured to serve a corresponding coverage area at a fixed known location and with respect to radio access point devices each configured to serve a corresponding relatively smaller coverage area in the wireless cellular communication network and which radio access point devices are readily movable from one location to another location the roaming history data comprising; location update information comprising local area code information associated with location areas of the wireless user devices relative to the base transceiver stations in the network; and measurement record information comprising indications of frequencies of signals received by the user devices; and analyze the location area code information in the location update information and frequency information in the measurement record information of the roaming history data of wireless user devices to determine a time between updates of the location update information and the measurement record information; and determine that a radio access point device is operating at a location other than its expected location when the determined time indicates that the updates of the location update information and the measurement record information would not be possible unless the radio access point is operating at the location other than its expected location. - View Dependent Claims (15, 16, 17, 18, 19)

20. A non-transitory computer readable medium storing instructions that, when executed by a processor, cause the processor to:
-
obtain roaming history data of wireless user devices in a wireless cellular communication network with respect to base transceiver stations each configured to serve a corresponding coverage area at a fixed known location and with respect to radio access point devices each configured to serve a corresponding relatively smaller coverage area in the wireless cellular communication network and which radio access point devices are readily movable from one location to another location, the roaming history data comprising; location update information comprising local area code information associated with location areas of the wireless user devices relative to the base transceiver stations in the network; and measurement record information comprising indications of frequencies of signals received by the user devices; and analyze the location area code information in the location update information and frequency information in the measurement record information of the roaming history data to determine a time between updates of the location update information and the measurement record information; and determine that, a radio access point device is operating at a location other than its expected location when the determined time indicates that the updates of the location update information and the measurement record information would not be possible unless the radio access point is operating at the location other than its expected location. - View Dependent Claims (21, 22, 23, 24)
