Patent ID: 8311561

Claim:
A method of location verification of an Access Point (AP) comprising: receiving a message carrying an IP address of the AP which is located in a coverage of a macro cell, and location information of the macro cell; querying, according to the IP address of the AP, a Connectivity Session Location and Repository Function (CLF) to obtain an access Line Location Identifier (ALLI) of the AP; determining whether a stored ALLI of the AP and stored location information of the macro cell exist; if the stored ALLI of the AP and the stored location information of the macro cell exist, determining that a location of the AP is not changed if the obtained ALLI of the AP is same as the stored ALLI of the AP, and the location information of the macro cell carried in the received message is same as the stored location information of the macro cell; and if the stored ALLI of the AP exists and the stored location information of the macro cell does not exist, determining whether the obtained ALLI of the AP is same as the stored ALLI of the AP; and determining that a location of the AP is changed if the obtained ALLI of the AP is different from the stored ALLI of the AP.
