Abstract
A method of sending reset message sequence number is provided. During a connected state handoff of an access terminal (AT) between a source access network (AN) and a target AN, the source AN sends a reset message sequence number of the AT to the target AN. The source AN adds the reset message sequence number of the AT to the message sent to the target AN. Thereby, the problem in the existing systems that the source AN cannot send the reset message sequence number of the AT to the target AN and, thus, the target AN cannot perform a reset process on the AT when the AT is switched from the source AN to the target AN, is solved. An access network (AN) and a communication system are also provided.
Claims9
A method for use in a connected state handoff of an access terminal (AT) between a source access network (AN) and a target AN, comprising:
- sending, by the source AN, an A16-Session Transfer Request Message to the target AN;
- receiving, by the source AN, an A16-Session Transfer Response Message from the target AN;
- sending, by the source AN, an A16-Session Transfer Complete Message to the target AN;
- wherein the A16-Session Transfer Complete Message carries a reset message sequence number of the AT.
A communication system for use in a connected state handoff of an access terminal (AT), comprising:
- a source AN, configured to send an A16-Session Transfer Request Message to a target AN;
- receive an A16-Session Transfer Response message from the target AN and send an A16-Session Transfer Complete Message to the target AN;
- the target AN, configured to receive the A16-Session Transfer Request Message from the source AN;
- send the A16-Session Transfer Response message to the source AN and receive the A16-Session Transfer Complete Message from the source AN;
- wherein the A16-Session Transfer Complete Message carries a reset message sequence number of the AT.
