System and Method for Enhancing the Probability of a Successful Communication Event Between the Users of Mobile Devices within an Intended Period of Time

A mobile device, comprising:

• a dialer, operatively coupled to at least one communication transceiver;
• a contact tracker, operatively coupled to the dialer, the contract tracker operative to:
• detect that a first call placed by a caller using the mobile device to a called party using a second mobile device was not answered by the called party using the second mobile device;
• obtain at least one candidate contact having a third mobile device, an association with the called party, and a probability of being in proximity to the called party at the time of the first call;
• and
• place a second call to the third mobile device.

A system comprising:

• a server, operatively coupled to a database, the database containing an association map having a plurality of nodes, each node corresponding to a contact and having at least one association with a different node, each association defining relationship categories comprising at least one of family member, coworker, business contact, or social contact, and location information, time and date for at least one node;
• a mobile device, operatively coupled to the server, comprising:
• a dialer, operatively coupled to at least one communication transceiver;
• a contact tracker, operatively coupled to the dialer, the contract tracker operative to:
• detect that a first call placed by a caller using the mobile device to a called party using a second mobile device was not answered by the called party using the second mobile device;
• obtain, from the server, at least one candidate contact having a third mobile device, an association with the called party, and a probability of being in proximity to the called party at the time of the first call;
• and
• place a second call to the third mobile device.
