Abstract

An apparatus and method of transmitting a Redirect message in a wireless communication system is described. A Redirect message is generated comprising an 8 bit MessageID field, a 16 bit StayAwayDuration field wherein the StayAwayDuration field indicates the units of second for which an access terminal will not make an access attempt at the sector sending this message, an 8 bit NumChannel field wherein the NumChannel indicates the number of channel records included in the message, an 8 bit RedirectReason field wherein the RedirectReason reflect the redirect reason and a Channel field wherein the Channel field indicates the channel that the access terminal should reacquire. The Redirect message is transmitted over a communication link.

Claims

1. A method of transmitting a Redirect message in a wireless communication system, characterized in that:

generating a Redirect message comprising an 8 bit MessageID field, a 16 bit StayAwayDuration field wherein the StayAwayDuration field indicates the units of second for which an access terminal will not make an access attempt at the sector sending this message, an 8 bit NumChannel field wherein the NumChannel indicates the number of channel records included in the message, an 8 bit RedirectReason field wherein the RedirectReason reflect the redirect reason and a Channel field wherein the Channel field indicates the channel that the access terminal should reacquire; and

transmitting the Redirect message over a communication link.

2. The method as claimed in claim 1, characterized in that providing the access terminal with information directing it to a set of different networks.

3. The method as claimed in claim 1, characterized in that:

setting the RedirectReason field with a value “

0×

00”

to indicate reserved;

setting RedirectReason field with a value “

0×

01”

to indicate network busy;

setting RedirectReason field with a value “

0×

02”

to indicate authentication or billing failure;

setting RedirectReason field with a value “

0×

03”

to indicate desired QoS unavailable;

setting RedirectReason field with a value “

0×

04”

to indicate no route to host;

setting RedirectReason field with a value “

0×

05”

to indicate network maintenance; and

setting RedirectReason field with a value “

0×

ff”

to indicate general failure.

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

a first set of instructions for generating a Redirect message comprising an 8 bit MessageID field, a 16 bit StayAwayDuration field wherein the StayAwayDuration field indicates the units of second for which an access terminal will not make an access attempt at the sector sending this message, an 8 bit NumChannel field wherein the NumChannel indicates the number of channel records included in the message, an 8 bit RedirectReason field wherein the RedirectReason reflect the redirect reason and a Channel field wherein the Channel field indicates the channel that the access terminal should reacquire; and

a second set of instructions for transmitting the Redirect message over a communication link.

5. An apparatus operable in a wireless communication system, characterized in that:

means for generating a Redirect message comprising an 8 bit MessageID field, a 16 bit StayAwayDuration field wherein the StayAwayDuration field indicates the units of second for which an access terminal will not make an access attempt at the sector sending this message, an 8 bit NumChannel field wherein the NumChannel indicates the number of channel records included in the message, an 8 bit RedirectReason field wherein the RedirectReason reflect the redirect reason and a Channel field wherein the Channel field indicates the channel that the access terminal should reacquire; and

means for transmitting the Redirect message over a communication link.

6. The apparatus as claimed in claim 5, characterized in that means for providing the access terminal with information directing it to a set of different networks.

7. The apparatus as claimed in claim 5, characterized in that:

means for setting the RedirectReason field with a value “

0×

to indicate authentication or billing failure;

means for setting the RedirectReason field with a value “

0×

03”

to indicate desired QoS unavailable;

means for setting the RedirectReason field with a value “

0×

04”

to indicate no route to host;

means for setting the RedirectReason field with a value “

0×

05”

to indicate network maintenance; and

means for setting the RedirectReason field with a value “

0×

ff”

to indicate general failure.

8. A method of receiving a Redirect message in a wireless communication system, characterized in that:

receiving a Redirect message comprising an 8 bit MessageID field, a 16 bit StayAwayDuration field wherein the StayAwayDuration field indicates the units of second for which an access terminal will not make an access attempt at the sector sending this message, an 8 bit NumChannel field wherein the NumChannel indicates the number of channel records included in the message, an 8 bit RedirectReason field wherein the RedirectReason reflect the redirect reason and a Channel field wherein the Channel field indicates the channel that the access terminal should reacquire; and

processing the received Redirect message and directing to a network indicated by the Redirect message.

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

a first set of instructions for processing a Redirect message comprising an 8 bit MessageID field, a 16 bit StayAwayDuration field wherein the StayAwayDuration field indicates the units of second for which an access terminal will not make an access attempt at the sector sending this message, an 8 bit NumChannel field wherein the NumChannel indicates the number of channel records included in the message, an 8 bit RedirectReason field wherein the RedirectReason reflect the redirect reason and a Channel field wherein the Channel field indicates the channel that access terminal should reacquire; and

a second set of instructions for processing the received Redirect message and directing to a network indicated by the Redirect message.

10. An apparatus operable in a wireless communication system, characterized in that:

means for receiving a Redirect message comprising an 8 bit MessageID field, a 16 bit StayAwayDuration field wherein the StayAwayDuration field indicates the units of second for which an access terminal will not make an access attempt at the sector sending this message, an 8 bit NumChannel field wherein the NumChannel indicates the number of channel records included in the message, an 8 bit RedirectReason field wherein the RedirectReason reflect the redirect reason and a Channel field wherein the Channel field indicates the channel that access terminal should reacquire; and

means for processing the received Redirect message and directing to a network indicated by the Redirect message.
