Multiple communication sessions in wireless communication devices
First Claim
1. A method of operating a communication system, the method comprising:
- receiving a first request to initiate a voice communication session with a wireless communication device;
determining a first spreading code for the voice communication session;
transferring the first spreading code for delivery to the wireless communication device;
exchanging communications of the voice communication session using the first spreading code;
receiving a second request to initiate a data communication session with the wireless communication device, wherein the voice communication session is at least partially concurrent with the data communication session;
determining a second spreading code for the data communication session, wherein the second spreading code is determined based upon the first spreading code;
transferring the second spreading code for delivery to the wireless communication device; and
exchanging communications of the data communication session using the second spreading code.

Abstract
What is disclosed is a method of operating a communication system. The method includes receiving a first request to initiate a first communication session with a wireless communication device, determining a first spreading code for the first communication session, and transferring the first spreading code for delivery to the wireless communication device. The method also includes receiving a second request to initiate a second communication session with the wireless communication device, determining a second spreading code for the second communication session, where the second spreading code is determined based upon the first spreading code, and transferring the second spreading code for delivery to the wireless communication device.

8. A method of operating a communication system, the method comprising:
-
in a wireless communication device, requesting to initiate a voice call through a wireless access system, receiving a first spreading code for the voice call, and exchanging communications of the voice call through the wireless access system using the first spreading code; in the wireless communication device, requesting to initiate a data session through the wireless access system, wherein the data session is at least partially concurrent with the voice call, receiving a second spreading code for the data session, wherein the second spreading code is determined based upon the first spreading code, and exchanging communications of the data session through the wireless access system using the second spreading code. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A communication system, comprising:
-
a wireless communication device configured to transfer a first request for a voice communication session to a wireless access system, receive a first spreading code for the voice communication session, and exchange communications of the voice communication session using the first spreading code; the wireless access system configured to establish the voice communication session with the wireless communication device based upon the first request, determine the first spreading code, transfer the first spreading code for delivery to the wireless communication device, and exchange the communications of the voice communication session with the wireless communication device using the first spreading code; the wireless communication device configured to transfer a second request for a data communication session to the wireless access system, receive a second spreading code for the data communication session, and exchange communications of the data communication session using the second spreading code, wherein the data communication session is at least partially concurrent with the voice communication session; the wireless access system configured to establish the data communication session with the wireless communication device based upon the second request, determine the second spreading code based upon the first spreading code, transfer the second spreading code for delivery to the wireless communication device, and exchange the communications of the data communication session with the wireless communication device using the second spreading code. - View Dependent Claims (16, 17, 18, 19, 20)
