Selecting a communications protocol

A system for selecting a communications protocol, comprising:

• a processor associated with a packet data serving node operable to:
• receive an initial request comprising a static Internet Protocol address from a mobile node;
• assign a dynamic address to the mobile node;
• receive a data packet from the mobile node;
• and
• determine whether the data packet comprises the dynamic address or a mobile Internet Protocol request to select a communications protocol;
• and
• a first protocol module coupled to the processor and operable to process the data packet using a mobile Internet Protocol process if the data packet comprises the mobile Internet Protocol request;
• and
• a second protocol module coupled to the processor and operable to process the data packet using a simple Internet Protocol process if the data packet comprises the dynamic address.

A system for selecting a communications protocol, comprising:

• a processor with a packet data serving node operable to:
• receive a initial request comprising a static Internet Protocol address from a mobile node, the static Internet Protocol address comprising a non-zero Internet Protocol address;
• assign a dynamic address to the mobile node;
• establish a point-to-point session with the mobile node;
• authenticate the mobile node;
• receive a data packet from the mobile node;
• and
• determine whether the data packet comprises the dynamic address or a mobile Internet Protocol request to select a communications protocol;
• and
• a first protocol module coupled to the processor and operable to process the data packet using a mobile Internet Protocol process if the data packet comprises the mobile Internet Protocol request by:
• transmitting the mobile Internet Protocol request to a home agent;
• receiving a mobile Internet Protocol reply from the home agent, the mobile Internet Protocol reply comprising an address assigned to the mobile node;
• and
• forwarding the mobile Internet Protocol reply to the mobile node;
• and
• a second protocol module coupled to the processor and operable to process the data packet using a simple Internet Protocol process if the data packet comprises the dynamic address.
