Method and apparatus for efficient channel assignment
First Claim
1. A method for a base site to perform efficient channel assignment comprising:
- transmitting overhead broadcast messaging containing information that identifies a fast call setup (FCS) channel;
receiving a request to establish a service with the remote unit; and
transmitting a channel assignment message to the remote unit via a paging channel in response to the request, wherein the channel assignment message assigns the remote unit to the FCS channel and the service by referencing the information previously transmitted.

Abstract
To address the need for efficiently performing channel assignment in a manner that reduces call setup time, the present embodiments provide an abbreviated channel assignment message (300) that references information stored by a remote unit (113). The information that is referenced can be removed from the message. By shrinking the channel assignment message in this manner, the present embodiment allows it to be transmitted in a paging slot without negatively impacting the battery life of listening units. Thus, the reduced-call-setup-time benefit of transmitting a channel assignment message in a paging slot can be realized without trading off battery life.

12. A method for a base site to perform efficient channel assignment comprising:
-
storing information that describes a wireless configuration used for service sessions with a remote unit;
receiving a request to establish a service with the remote unit; and
transmitting a channel assignment message to the remote unit via a paging channel in response to the request, wherein the channel assignment message assigns the remote unit to a traffic channel and the service by referencing wireless configuration information used for a previous service session with the remote unit. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. A method for a remote unit to facilitate efficient channel assignment comprising:
-
receiving from a radio access network (RAN) overhead broadcast messaging containing information that identifies a fast call setup (FCS) channel;
storing the information that identifies the FCS channel; and
receiving a channel assignment message from the RAN via a paging channel, wherein the channel assignment message assigns the remote unit to the FCS channel and a service by referencing the information that identifies the FCS channel.

20. A method for a remote to facilitate efficient channel assignment comprising:
-
storing information that describes a wireless configuration used for service sessions with a radio access network (RAN);
receiving a channel assignment message from the RAN via a paging channel, wherein the channel assignment message assigns the remote unit to a traffic channel and a service by referencing wireless configuration information used for previous service sessions with the remote unit.

21. A radio access network (RAN) comprising:
-
a transmitter;
a receiver; and
a controller, coupled to the transmitter and receiver, adapted to instruct the transmitter to transmit overhead broadcast messaging containing information that identifies a fast call setup (FCS) channel, adapted to store information that describes a wireless configuration used for service sessions with a remote unit, adapted to receive via the receiver a request to establish a service with the remote unit, and adapted to instruct the transmitter to transmit a channel assignment message to the remote unit via a paging channel in response to the request, wherein the channel assignment message assigns the remote unit to a traffic channel and the service by referencing at least one of the information previously transmitted and wireless configuration information used for a previous service session with the remote unit.

22. A remote unit comprising:
-
a receiver;
a transmitter; and
a processor, coupled to the transmitter and receiver, adapted to receive, via the receiver from a radio access network (RAN), overhead broadcast messaging containing information that identifies a fast call setup (FCS) channel, adapted to store the information that identifies the FCS channel, adapted to store information that describes a wireless configuration used for service sessions with the RAN, and receive via the receiver a channel assignment message from the RAN via a paging channel, wherein the channel assignment message assigns the remote unit to a traffic channel and a service by referencing at least one of wireless configuration information used for previous service sessions with the remote unit and the information that identifies a FCS channel.
