A method comprising: storing, by a computer system, information about a location of a first wireless device associated with a first user profile of a first subscriber; storing, by the computer system, information about a location of a second wireless device associated with a second user profile of a second subscriber; determining, by the computer system, a frequency of proximity over a period of time and a duration of proximity for the first and second wireless devices based on the stored information about the location of the first and second wireless devices; identifying, by the computer system, the second wireless device as being substantially collocated with the first wireless device when the frequency of proximity over the period of time is greater than a first predetermined threshold and the duration of proximity is greater than a second predetermined threshold; and in response to said identifying the second wireless device as being substantially collocated with the first wireless device, generating an association between the first user profile and the second wireless device to indicate that the first wireless device and the second wireless device are used by a single subscriber.
