Abstract

Method and apparatus for effecting handoff in a system supporting both wireless and packet date service communications. In one embodiment, the serving network provides information to the target network sufficient to establish the Point-to-Point Protocol (PPP) connections for handoff. In an alternate embodiment, the serving network and the target network do not share capabilities with respect to concurrent multiple service instances. When the serving network knows the status of the target network, the serving network takes responsibility for the handoff.

Claims (21)

1. A method for handoff in a communication system, comprising:
establishing a main link and a secondary link between a mobile unit a serving packet data service node via a serving radio network;
initiating a handoff from the serving radio network to a target radio network;
and sending a message to a target packet data service node identifying the main link.
2. The method as in claim 1, further comprising:
Establishing a main link and a secondary link between the mobile unit and the target packet data service node.
3. The method as in claim 2, further comprising:
sending a Point-to-Point Protocol (PPP) configuration request from the target packet data service node to the mobile unit.
4. The method as in claim 1, wherein the main link is associated with a first service instance, and the secondary link is associated with a second service instance.
5. The method as in claim 4, wherein the second service instance is a Voice over Internet Protocol service.
6. The method as in claim 1, wherein the serving packet data service node and the target packet data service node incorporate compatible protocols.
7. The method as in claim 6, wherein the compatible protocols are a same protocol.
8. The method as in claim 1, wherein the initiating further comprises:

sending a pilot report from the mobile unit to the serving radio network.
9. The method as in claim 8, further comprising:
sending a handoff message form the service radio network to the target radio network.
10. The method as in claim 9, wherein the pilot report identifies a pilot signal strength.
11. The method as in claim 1, wherein the message is a reply to a registration request.
12. A method for handoff in a communication system, comprising:
initiating handoff from a serving radio network to a target radio network;
receiving a registration request from a target radio network;
sending a link initiation message to a mobile unit on a first link via the target radio network, the first link associated with a first service instance;
and sending the link initiation message to the mobile unit on a second link via the target radio network, the second link associated with a second service instance.
13. The method as in claim 12, wherein the first link is a Point-to-Point Protocol (PPP) connection.
14. The method as in claim 13, wherein the second link is an auxiliary link for Voice over Internet Protocol.
15. The method as in claim 12, further comprising:
requesting registration from a serving packet data service node.
16. A method for handoff in a communication system, comprising:

sending main link information of the serving radio network to the target radio network; and performing handoff to the target radio network.
18. An apparatus in a communication system, comprising:
means for establishing a main link and a secondary link between a mobile unit a serving packet data service node via a serving radio network;
means for initiating a handoff from the serving radio network to a target radio network; and means for sending a message to a target packet data service node identifying the main link.
19. An apparatus in a communication system, comprising:
means for initiating handoff from a serving radio network to a target radio network;
means for receiving a registration request from a target radio network;

means for sending a link initiation message to a mobile unit on a first link via the target radio network, the first link associated with a first service instance; and means for sending the link initiation message to the mobile unit on a second link via the target radio network, the second link associated with a second service instance.
20. An apparatus in a communication system, comprising:
means for initiating a handoff from a serving radio network to a target radio network, the serving radio network adapted to support multiple service instances, the target radio network adapted to support one service instance;
means for terminating a secondary link to the serving radio network;
means for sending main link information of the serving radio network to the target radio network; and means for performing handoff to the target radio network.
21. A packet data service node in a communication system, adapted to:
establish a main link and a secondary link with a mobile unit via a serving radio network;
initiate a handoff to a target radio network; and send a message to a target packet data service node identifying the main link.
