ABSTRACT:
A system, method and node for supporting PDSN load balancing in a CDMA2000 network. A mobile node (MN) sends an origination message to a BSC/PCF that sends a registration request indicating that it supports load balancing according to the invention to the manager part of a PDSN that selects an agent to take care of the connection and redirects the request to it. The agent then validates the request and sends a reply to the BSC/PCF indicating that the initial request has been redirected. The reply also comprises the IP address of the agent. The BSC/PCF then sets up an A10 connection with the agent, and the MN and the agent negotiate a PPP session. There is further a method of setting up a connection between two entities, via a third entity.
