System and method for interworking SCFs and protocols in open service gateway

A method of interworking service capability features and protocols in an open service gateway, the method comprising:

• (a) requesting a service by a computer to be provided from an open application server to a service capability feature in the open service gateway, wherein a protocol stack enables the open service gateway to interface with a plurality of communications networks of different types, the protocol stack including a message identifier and a protocol identifier, the service capability features having different ranges of the message identifier;
• (b) generating a protocol message required to accomplish the service, and encoding the protocol message to include the message identifier which differentiates the service capability feature from other service capability features;
• (c) transmitting the encoded protocol message to a unit for maintaining a protocol corresponding to the service capability features;
• and
• (d) allocating the protocol identifier to the transmitted protocol message, the protocol identifier differentiating the protocols from one another.

• (a) receiving a protocol message which includes a protocol identifier and a message identifier, the protocol identifier differentiating the protocols from one another and the message identifier differentiating the service capability features from one another, the service capability features of the open service gateway interfacing with a plurality of communication networks of different types through a protocol stack, wherein the service capability features have different ranges of the message identifier;
• (b) decoding the received protocol message by a computer;
• (c) checking the protocol identifier included in the protocol message, and transmitting the protocol message to a unit for maintaining a protocol corresponding to the protocol identifier;
• and
• (d) checking the message identifier included in the protocol message, and providing the protocol message to a corresponding service capability feature.
