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, comprising:

employing a computer processor to execute instructions retained in a non-transitory computer-readable storage medium to perform operations, comprising;

generating a Redirect message comprising an 8 bit MessageID field, a 16 bit StayAwaypuration field, wherein the StayAwaypuration field indicates the units in seconds that an access terminal does not attempt to access a sector sending the Redirect message, an 8 bit NumChannel field, wherein the NumChannel field indicates a number of channel records included in the Redirect message, an 8 bit RedirectReason field, wherein the RedirectReason field indicates a reason for redirect, and a Channel field wherein the Channel field indicates a channel that the access terminal is to reacquire; and

transmitting the Redirect message over a communication link.

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

3. The method as claimed in claim 1, further comprising setting the RedirectReason field to at least one of:

a value of “

0x00”

a value of “

0x03”

to indicate desired QoS unavailable;

a value of “

0x04”

to indicate no route to host;

a value of “

0x05”

to indicate network maintenance;

or

a value of “

0xff”

to indicate general failure.

4. A non-transitory computer readable storage medium comprising computer executable instructions that, in response to execution, cause a computing system to perform operations, comprising:

generating a Redirect message comprising an 8 bit MessageID field, a 16 bit StayAwaypuration field, wherein the StayAwaypuration field indicates the units in seconds that an access terminal does not attempt to access a sector sending the Redirect message, an 8 bit NumChannel field, wherein the NumChannel field indicates a number of channel records included in the Redirect message, an 8 bit RedirectReason field, wherein the RedirectReason field indicates a reason for redirect, and a Channel field, wherein the Channel field indicates a channel that the access terminal is to reacquire; and

transmitting the Redirect message over a communication link.

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

means for generating a Redirect message comprising an 8 bit MessageID field, a 16 bit StayAwaypuration field, wherein the StayAwaypuration field indicates the units in seconds that an access terminal does not attempt to access a sector sending the Redirect message, an 8 bit NumChannel field, wherein the NumChannel field indicates a number of channel records included in the Redirect message, an 8 bit RedirectReason field, wherein the RedirectReason field indicates a reason for redirect, and a Channel field wherein the Channel field indicates a channel that the access terminal is to reacquire; and

means for transmitting the Redirect message over a communication link.

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

7. The apparatus as claimed in claim 5, comprising means for setting the RedirectReason field to at least one of:

a value of “

0x00”

to indicate reserved;

a value of “

0x01”

to indicate network busy;

a value of “

0x02”

to indicate authentication or billing failure;

a value of “

0x03”

to indicate desired QoS unavailable;

a value of “

0x04”

to indicate no route to host;

a value of “

0x05”

to indicate network maintenance;

or

a value of “

0xff”

to indicate general failure.

8. A method of receiving a Redirect message by an access terminal in a wireless communication system, comprising:
