Method and system for supporting simultaneous data sessions of dissimilar access networks

A PDSN comprising:

• a first network communication interface for connection to a radio access network;
• a second network communication interface for connection to a packet network;
• a processing unit;
• data storage;
• correlation-data stored in the data storage, the correlation-data defining parameters associated with an ongoing data session, wherein the parameters correspond to at least one of a first RP transfer protocol or a second RP transfer protocol;
• and
• a protocol abstraction routine stored in the data storage and executable by the processing unit to identify if a data packet received from a radio access network is associated with at least one of the first RP transfer protocol or the second RP transfer protocol, and to decapsulate the data packet according to the associated RP transfer protocol for transmission of the data packet between the radio access network and a packet network.

A method for supporting simultaneous data sessions on dissimilar access networks, the method comprising:

• receiving a data packet from a first network;
• identifying if the data packet corresponds to at least one of a first RP transfer protocol or a second RP transfer protocol;
• at least one of encapsulating or decapsulating the data packet according to the first RP transfer protocol when the data packet is associated with the first RP transfer protocol;
• at least one of encapsulating or decapsulating the data packet according to the second RP transfer protocol when the data packet is associated with the second RP transfer protocol;
• and
• transmitting the data packet to a second network.
