Abstract

In some examples, a method of tracking device location in a communication network is described. The method may include, detecting at a Machine Type Communication (MTC) device, location indicia from one or more access points (APs) in a vicinity of the MTC device. The method may also include 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. The method may also include reporting the detected location indicia to a network end in the communication network. The network end may be configured to update location information of the MTC device in response to receiving the detected location indicia.

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.

2. The method of claim 1, wherein the location indicia include, for each of the one or more access points in the vicinity of the MTC device, at least one of a serial number of the access point, a received signal strength of a signal received from the access point, or an incoming angle of the signal received from the access point.

3. The method of claim 1, wherein 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 comprises at least one of:

determining that the location indicia includes a serial number of an access point with which the MTC device was not previously in communication during a predetermined time period;

or

determining that the location indicia excludes a serial number of an access point with which the MTC device was previously in communication during the predetermined time period.

4. The method of claim 1, wherein the location information of the MTC device comprises data representing a sector within a coverage area of a serving access point of the MTC device, the sector being determined by the network end, based on the reported location indicia, to cover the current location of the MTC device.

5. The method of claim 1, wherein:

detecting location indicia from one or more access points in the vicinity of the MTC device is performed periodically by the MTC device with a predetermined frequency;

the MTC device comprises a static MTC device configured to remain at a fixed location for a long term or a low speed mobile MTC device configured to change locations during the long term;

the predetermined frequency is a first predetermined frequency if the MTC device comprises a static MTC device or a second predetermined frequency if the MTC device comprises a low speed mobile MTC device; and

the first predetermined frequency is less than the second predetermined frequency.

6. The method of claim 1, wherein the detected location indicia is reported by the MTC device to the network end without the MTC device being called by the network end and in response to the MTC device determining that the current location of the MTC device is different than the preceding location of the MTC device.

7. A non-transitory computer-readable storage medium having computer-executable instructions stored thereon that are executable by a computing device to perform operations comprising:

detecting location indicia from one or more access points in a vicinity of a Machine Type Communication (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
