Patent ID: 8694023

Claim:
A method of tracking device location in a communication network, the method comprising: detecting, at a Machine Type Communication (MTC) device, location indicia from one or more access points in a vicinity of the MTC device; determining, based on the detected location indicia, that a current location of the MTC device is different than a preceding location of the MTC device, including: determining that a received signal strength of a signal received from at least one of one or more candidate access points is above a first predetermined threshold for a predetermined time period; determining that a received signal strength of a signal received from a serving access point is below a second predetermined threshold for the predetermined time period; and determining that an incoming angle of a signal received from at least one of the one or more access points is different than a previous incoming angle of a signal previously received from the at least one of the one or more access point; and reporting the detected location indicia to a network end in the communication network, wherein the network end is configured to update location information of the MTC device in response to receiving the detected location indicia; wherein the first predetermined threshold is −80 dBm, the predetermined time period is between five to ten milliseconds, and the second predetermined threshold is −90 dBm.
