Circuit switched fallback procedure

摘要

A CS fallback procedure handles conflict that may arise when handover operations occur during CS fallback. If CS fallback is initiated for an access terminal and handover of that access terminal is then initiated before the CS fallback completes, the target for the handover is informed of the CS fallback so that the target may perform the appropriate CS fallback operations.

1. A method of communication, comprising:
sending a first message to a first access point, wherein the first message includes a circuit switched fallback indicator associated with a circuit switched fallback procedure for an access terminal; determining, after the first message is sent to the first access point, that handover of the access terminal from the first access point to a second access point has been initiated during the circuit switched fallback procedure at the first access point; and sending a second message to the second access point as a result of the determination, wherein the second message sent to the second access point includes the circuit switched fallback indicator associated with the circuit switched fallback procedure for the access terminal.
