Radio network control
First Claim
1. A method comprising,in connection with a wireless network that includes a first radio network controller, a second radio network controller, a first radio node, and a second radio node,establishing a first session for a first access terminal on the first radio network controller via the first radio node,establishing a second session for a second access terminal on the second radio network controller via the second radio node,communicating first packets over a first traffic channel between the first access terminal and the first radio network controller using the first radio node and without the first packets passing through the second radio network controller,maintaining the first traffic channel as the first access terminal moves from a coverage area of the first radio node to a coverage area of the second radio node,communicating second packets over the first traffic channel between the first access terminal and the first radio network controller using the second radio node and without the second packets passing through the second radio network controller while the first access terminal remains in an active state in any portion of the coverage area of the second radio node, andestablishing a new session for the first access terminal on the second radio network controller or performing an inter-RNC dormant handoff from the first radio network controller to the second radio network controller when the first access terminal is in a dormant state in the coverage area of the second radio node.

Abstract
A first session is established for a first mobile access terminal on a first radio network controller via a first radio node. A first traffic channel is established between the first mobile access terminal and the first radio network controller. A first plurality of packets are sent and received over the first traffic channel. The first plurality of packets travel between a first radio node and the first radio network controller without passing through a second radio network controller. The first traffic channel is maintained as the first access terminal moves from a coverage area of the first radio node to a coverage area of a second radio node. A second plurality of packets travel between the second radio node and the first radio network controller without passing through another radio network controller.

24. A computer program product, on a computer readable medium tangibly embodied in an information carrier, and to work in a wireless network including a first and a second radio network controller and a first and a second radio node, the computer program product comprising instructions operable to cause data processing apparatus to:
-
establish a first session for a first access terminal on the first radio network controller via the first radio node, establish a second session for a second access terminal on the second radio network controller via the second radio node, establish a first traffic channel between the first access terminal and the first radio network controller, communicate first packets over the first traffic channel between the first radio node and the first radio network controller without the first packets passing through the second radio network controller, maintain the first traffic channel as the first access terminal moves from a coverage area of the first radio node to a coverage area of the second radio node, and while the first access terminal remains in an active state in any portion of the coverage area of the second radio node, communicate second packets over the first traffic channel between the first access terminal the first radio network controller using the second radio node and without the second packets passing through another radio network controller. - View Dependent Claims (25)

26. A wireless network comprising,
a first radio network controller, a second radio network controller, a first radio node, a second radio node, a first access terminal that is associated with a first session established on the first radio network controller via the first radio node and a first traffic channel established with the first radio network controller, the first access terminal communicating first packets over the first traffic channel, between the first radio node and the first radio network controller without the first packets passing through the second radio network controller, and a second access terminal that is associated with a second session established on the second radio network controller via the second radio node, wherein the first traffic channel is maintained as the first access terminal moves from a coverage area of the first radio node to a coverage area of the second radio node, and wherein second packets are communicated between the first access terminal and the first radio network controller using the second radio node and without the second packets passing through the second radio network controller while the first access terminal remains in an active state in any portion of the coverage area of the second radio node.
