User equipment geolocation using a history of network information

Network equipment, comprising:

• a processor;
• and
• a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising:
• obtaining network information associated with a user equipment, the network information comprising a serving cell identification of a serving cell that serves the user equipment and a timing advance value indicating a timing advance associated with the user equipment;
• looking up the serving cell and the timing advance value in a location lookup data structure for the user equipment, wherein the location lookup data structure comprises frequently repeated serving cells, correlated timing advance values, and correlated predetermined user equipment locations, wherein the frequently repeated serving cells correspond to frequently-visited locations of the user equipment, wherein a predetermined frequency criterion defines a frequency needed to qualify as a frequently repeated serving cell, wherein the location lookup data structure for the user equipment further comprises information about a secondary location of secondary network node associated with a neighboring cell adjacent to a frequently repeated serving cell of the frequently repeated serving cells and a secondary correlated timing advance value associated with the neighboring cell while the user equipment was served by the neighboring cell;
• and
• in response to the serving cell identification and the timing advance value being determined to match a frequently repeated serving cell of the frequently repeated serving cells and a correlated timing advance value of the correlated timing advance values, applying a correlated predetermined user equipment location of the correlated predetermined user equipment locations to the user equipment.

A non-transitory machine-readable medium, comprising executable instructions that, when executed by a processor, facilitate performance of operations, comprising:

• determining location information to associate with a frequently repeated serving cell and timing advance value pair,
• wherein the frequently repeated serving cell and timing advance value pair is frequently repeated, based on a frequency criterion, in a history of network information associated with a user equipment, wherein the frequency criterion is selected to define a frequency of visitation needed to quality as a frequently repeated serving cell, and
• wherein determining the location information comprises:
• identifying a neighbor cell and neighbor timing advance value pair in the history of network information, wherein the neighbor cell is a neighbor of the frequently repeated serving cell;
• identifying candidate user equipment locations using arc intersections of a first arc formed using the frequently repeated serving cell and timing advance value pair and a second arc formed using the neighbor cell and neighbor timing advance value pair;
• and
• using azimuth information associated with at least one of the frequently repeated serving cell and the neighbor cell to select a candidate user equipment location from among the candidate user equipment locations, wherein the location information comprises the selected candidate user equipment location;
• determining secondary location information to associate with the frequently repeated serving cell, wherein the secondary location information is based on a secondary location of a secondary access node associated with a neighboring cell of the frequently repeated serving cell and secondary correlated timing advance information indicating a timing advance while the user equipment was served by the neighboring cell;
• and
• associating the location information and the secondary location information with the frequently repeated serving cell and timing advance value pair in a location lookup table for the user equipment.
