Circuit switched fallback procedure
First Claim
Patent Images
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.

Abstract
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.

16. An apparatus for communication, comprising:
-
a circuit switched fallback controller configured to send 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; and a handover controller configured to determine, 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, wherein the circuit switched fallback controller is further configured to send a second message to the second access point as a result of the determination, and 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. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)

31. An apparatus for communication, comprising:
-
means for 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; means for 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 means for 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. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45)

46. A computer-program product, comprising:
a non-transitory computer-readable medium comprising code for causing a computer to; send 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; determine, 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 send 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. - View Dependent Claims (47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60)
