Abstract: A base location associated with a user of a communication device can be determined. A location identifier component can determine the base location, such as a home location, of the user based on activity data and/or other data, wherein the activity data can be obtained from base stations with which the user's communication device communicates during a defined time period. The location identifier component can designate a defined area as the base location, wherein the defined area can be associated with the base station with which the communication device most frequently communicates during the defined time period or can be an area that is determined based on the activity data and the other data, in accordance with a defined location algorithm. To facilitate maintaining the privacy of users, the activity data can be anonymized and/or the granularity of defining the base location can be adjusted.
