Abstract: Method and system for performing handoff in wireless networks. According to an embodiment, the present invention provides a method for wireless communication. The method includes providing an access terminal that is configured to perform wireless IP communication. The method also includes providing a first wireless connection for the access terminal by a first access node. The method further includes providing a first network access for the access terminal by a first connectivity node. Additionally, the method includes obtaining a plurality of addresses for the access terminal. The plurality of address includes a first address and a second address. The first address is associated with a first priority level. The second address is associated with a second priority level. The method additionally includes storing the plurality address by a home agent. The method also includes initiating a handoff process for switching from the first connectivity node to a second connectivity node.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A system and method are provided for using differentiated telephone numbers to determine whether to perform a vocoder bypass. In an exemplary embodiment, a mobile station may call a terminating node. An intermediate entity may search an identifier of the terminating node for a predetermined aspect. If the predetermined aspect is found, the terminating node may be a mobile station, and the intermediate entity may perform a vocoder bypass. If the predetermined aspect is not found, the terminating node may be a non-mobile station, and the intermediate entity may perform vocoding.
