Abstract

A system and method for identifying transient friends for a social network of a user are provided. A transient friend processing function obtains locations of a number of users or locations otherwise associated with the number of users. In order to identify transient friends for a first user, the transient friend processing function identifies other users associated with locations within a proximate area of the first user. For each of the identified users, the transient friend processing function compares a user profile of the first user to a user profile of the identified user to determine whether to add the identified user as a transient friend of the first user. If the transient friend processing function determines that the identified friend is to be added as a transient friend of the first user, the identified friend is then added as a transient friend of the first user.

Claims

1. A method comprising:

identifying, for a first user, a second user that is associated with a location within a proximate area of the first user as a transient friend of the first user in a social network of the first user;

adding the second user as a transient friend of the first user; and

after adding the second user as a transient friend of the first user, monitoring the second user such that a status of the second user as a transient friend of the first user is based upon whether the second user continues to be associated with a location within the proximate area of the first user;

wherein monitoring the second user comprises;

determining that the second user is no longer associated with a location within the proximate area of the first user;

waiting at least an amount of time defined by a proximity exit delay after determining that the second user is no longer associated with a location within the proximate area of the first user;

after waiting the at least an amount of time defined by the proximity exit delay, determining whether the second user is associated with a location outside the proximate area of the first user; and

if a determination is made that the second user is associated with a location outside the proximate area of the first user after waiting the at least an amount of time defined by the proximity exit delay, removing the second user as a transient friend of the first user.
