Relay Access Node with Separate Control and Transport Signaling for Session-based Communications

  Bruno R. Preiss, Giyeong Son, and Allan Lewis, April 2009. Patent Application[36].

A system and method of control and management of communications between endpoints using access nodes, comprising receiving data at a first access node from a first endpoint using a protocol that does not support session-based communications, initiating a communication session between the first access node and second access node associated with a second endpoint using a transport-independent signaling protocol, wherein the session is uniquely identified using source and destination identifiers and payload type of the data received from the first endpoint, during the communication session between the first access node and second access node controlling routing of data transfer between the first and second endpoints, and terminating the communication session responsive to determining that the transfer of data has stopped.
