1. A method for exchanging digital information using mobile access terminals in a wireless network, the method comprising:
- transmitting packets over a first traffic channel, established between a first mobile access terminal and a first radio network controller, via a first radio node without passing through a second radio network controller;
transmitting packets over a second traffic channel, established between a second mobile access terminal and the second radio network controller, via a second radio node without passing through the first radio network controller;
maintaining the first traffic channel between the first access terminal and the first radio network controller when packets are received from or transmitted to the first access terminal via the second radio node; and
transmitting packets received from the first access terminal to an external network.

Abstract
In a radio access network, multiple radio network controllers are connected to several radio nodes using a network. The interconnected radio network controllers and radio nodes are addressable, and, therefore, each radio network controller can communicate directly with each radio node and visa versa. The radio access network can be configured to avoid active handoffs between radio network controllers by maintaining a traffic channel set up between an access terminal and a radio network controller even as the flow.
