A method is provided of targeting short message service (SMS) message for delivery to a mobile station. When an SMS center (SMSC) in a cellular network receives an SMS message and is to send it to a mobile station, the SMS center determines the location of the mobile station either directly or indirectly via a location register. The SMS center correlates that location with a particular base transceiver station serving that location. The SMS center then causes the SMS message to be delivered to the mobile station via that particular base transceiver station. The SMS center thus can avoid sending SMS messages to all base transceiver stations in a given area, thereby conserving network resources.

Localized SMS messaging based on location of a mobile station

A method for handing off a wireless communication session between a first radio network and a second radio network. The method includes handing off the wireless communication session from the first wireless communication to the second radio network based on a first trigger. The method also includes handing off the wireless communication session from the second wireless communication to the first radio network based on a second trigger, wherein the second trigger is different than the first trigger.

Method and system for asymmetric handoff of wireless communication sessions

A system and method for managing multiple mobile stations provisioned for use by a single user with a common mobile identification number (MIN). In an advanced intelligent network, a call control system may receive requests to set one of the multiple mobile stations to an active state. The call control system may also receive requests to set one or more of the multiple mobile stations to an inactive state. The call control system stores the active or inactive indication in a subscriber profile database. When a request is made to register one of the multiple mobile stations for service, the call control system determines if the mobile station is active or inactive. If the mobile station is inactive, it is not permitted to register. If the mobile station is active, it is permitted to register.
