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.
