1. A method comprising:
- enabling many-to-many communication among radio network controllers and radio nodes through a packet network,establishing a first session for a first access terminal on a first radio network controller through a first radio node, andmaintaining the first session on the first radio network controller when the first access terminal is dormant and moves from a coverage area of the first radio node to any portion of a coverage area of a second radio node through which a second access terminal has a second session on a second radio network controller without transferring the first session to the second radio network controller;
wherein when the first access terminal is dormant, the first access terminal has the first session established on the first radio network controller and does not have any traffic channel established with any radio network controller; and
wherein when the second access terminal is dormant, the second access terminal has the second session established on the second radio network controller and does not have any traffic channel established with any radio network controller.

Abstract
In connection with a mobile wireless subnetwork having multiple radio network controllers and multiple radio nodes, a session established for an access terminal is associated with a serving radio network controller. The association is maintained as the access terminal moves from the coverage area of one radio node to the coverage area of another radio node within the same subnetwork. Access channel packets are routed from an access terminal having an existing session to the serving radio network controller by determining the IP address of the serving radio network controller using a session identifier.

9. A method performed by a radio node, the method comprising:
-
receiving routing information for a first session between a dormant first access terminal and a first radio node controller, the first session having been maintained by a first radio node; receiving a notification that the dormant first access terminal has moved into a coverage area of the radio node; and while maintaining a second session between a dormant second access terminal and a second radio node controller, maintaining the first session between the dormant first access terminal and the first radio node controller; wherein the dormant first access terminal does not have any traffic channel established with any radio network controller; and wherein the dormant second access terminal does not have any traffic channel established with any radio network controller. - View Dependent Claims (10, 11, 12, 13)

14. A system comprising:
a radio node in a mobile wireless network, the radio node configured to; receive routing information for a first session between a dormant first access terminal and a first radio node controller, the first session having been maintained by a first radio node; receive a notification that the dormant first access terminal has moved into a coverage area of the radio node; and while maintaining a second session between a dormant second access terminal and a second radio node controller, maintain the first session between the dormant first access terminal and the first radio node controller; wherein the dormant first access terminal does not have any traffic channel established with any radio network controller; and wherein the dormant second access terminal does not have any traffic channel established with any radio network controller. - View Dependent Claims (15, 16, 17, 18)
