Abstract

Some embodiments provide a method of activating a packet transport channel (PTC) in a communication system that includes a first licensed wireless communication system and a second generic access network (GAN) that has a generic access network controller (GANC). The GANC is communicatively coupled to the first communication system through a universal mobile telecommunication system (UMTS) terrestrial radio access network (UTRAN) Iu interface. The method sends a GA-PSR activate PTC request message from the GANC to a user equipment (UE). The message comprises a terminal endpoint identifier (TEID) that the GANC assigns to the UE. The message also receives a GA-PSR activate PTC acknowledge message from the UE at the GANC.

Claims

1. A method of activating a packet transport channel (PTC) in a communication system comprising a first licensed wireless communication system and a second generic access network (GAN) comprising a generic access network controller (GANC), wherein the GANC is communicatively coupled to the first communication system through a universal mobile telecommunication system (UMTS) terrestrial radio access network (UTRAN) Iu interface, the method comprising:

a) sending a GA-PSR activate PTC request message from the GANC to a user equipment (UE), wherein the message comprises a terminal endpoint identifier (TEID) that the GANC assigns to the UE;

b) receiving a GA-PSR activate PTC acknowledge message from the UE at the GANC.

2. The method of claim 1, wherein the GA-PSR activate PTC request message further comprises a GANC IP address.

3. The method of claim 1, wherein the GA-PSR activate PTC request message further comprises a GANC TEID.

4. The method of claim 3, wherein the GANC sets the GANC IP address to an IP address associated with the first communication system when the GANC is configured to allow the UE to send PTC packets directly to the first communication system.

5. The method of claim 3, wherein the GANC sets the GANC IP address to an IP address local to the GANC when the GANC is not configured to allow the UE to send PTC packets directly to the first communication system.

6. The method of claim 3, wherein the GANC sets the GANC TEID to a TEID associated with the first communication system when the GANC is configured to allow the UE to send PTC packets directly to the first communication system.

7. The method of claim 3, wherein the GANC sets the GANC TEID to a GANC allocated TEID system when the GANC is not configured to allow the UE to send PTC packets directly to the first communication system.
