Abstract

A method and apparatus for establishing an access channel in a wireless communication system is provided, comprising receiving an AccessGrant on a carrier on which the last probe was transmitted and ending an access probe transmission upon receiving the AccessGrant. A method and apparatus is further provided, comprising determining expiration of an access grant timer and ending an access probe transmission upon the expiration of the timer. A method and apparatus is further provided comprising receiving an IdleState.IdleHO indication and ending an access probe transmission upon receiving the IdleState.IdleHO indication. A method and apparatus is further provided receiving a new AttemptAccess command, wherein the AttemptAccess command is processed after a current probe transmission ends and ending an access probe transmission on receiving the new AttemptAccess command.

Claims

1. A method of establishing an access channel in a wireless communication system, characterized in that:

receiving an AccessGrant on a carrier on which the last probe was transmitted; and

ending an access probe transmission upon receiving the AccessGrant.

2. A computer-readable medium including instructions stored thereon, characterized in that:

a first set of instructions for receiving an AccessGrant on the carrier on which the last probe was transmitted; and

a second set of instructions for ending access probe transmission upon receiving the access grant.

3. An apparatus operable in wireless communication system, the apparatus characterized in that:

means for receiving an AccessGrant on the carrier on which the last probe was transmitted; and

means for ending access probe transmission upon receiving the AccessGrant.

4. A method of establishing an access channel in a wireless communication system, characterized in that:

determining expiration of an access grant timer; and

ending an access probe transmission upon the expiration of the timer.

5. A computer-readable medium including instructions stored thereon, characterized in that:

a first set of instructions for determining expiration of an access grant timer; and

a second set of instructions for ending access probe transmission upon the expiration of the timer.

6. An apparatus operable in wireless communication system, the apparatus characterized in that:

means for determining expiration of an access grant timer; and

means for ending access probe transmission upon the expiration of the timer.

7. A method of establishing an access channel in a wireless communication system, characterized in that:

receiving an IdleState.IdleHO indication; and

ending an access probe transmission upon receiving the IdleState.IdleHO indication.

8. A computer-readable medium including instructions stored thereon, characterized in that:

a first set of instructions for receiving an IdleState.IdleHO indication; and

a second set of instructions for ending access probe transmission upon receiving the IdleState.IdleHO indication.

9. An apparatus operable in wireless communication system, the apparatus characterized in that:

means for receiving an IdleState.IdleHO indication; and

means for ending access probe transmission upon receiving the IdleState.IdleHO indication.

10. A method of establishing an access channel in a wireless communication system characterized in that:

receiving a new AttemptAccess command, wherein the AttemptAccess command is processed after a current probe transmission ends; and

ending an access probe transmission on receiving the new AttemptAccess command.

11. A computer-readable medium including instructions stored thereon, characterized in that:

a first set of instructions for receiving a new AttemptAccess command, wherein the AttemptAccess command is processed after the current probe transmission ends; and

a second set of instructions for ending access probe transmission on receiving the new AttemptAccess command.

12. An apparatus operable in wireless communication system, the apparatus characterized in that:

means for receiving a new AttemptAccess command, wherein the AttemptAccess command is processed after the current probe transmission ends; and

means for ending access probe transmission on receiving the new AttemptAccess command.
