Abstract

Provided are a system and method for interworking Service Capability Features (SCFs) and protocols in an open service gateway. The system includes service capability features that generate and process various protocol messages, and a protocol stack that enables an interwork with a communications network. The protocol stack includes: one or more units that maintain various protocols, a unit that performs data connection and transmits and processes messages, and a unit that manages the various protocols. In the protocol stack, protocol identifiers that differentiate the protocols from one another, and message identifiers that differentiate service capability features from one another are stored in the unit that manages the various protocols.

Claims

1. A system for interworking service capability features and protocols in an open service gateway, the system comprising:

a computer including;

the service capability features generating and processing various protocol messages; and

a protocol stack enabling an interwork between the open service gateway and a plurality of communications networks of different types, wherein the protocol stack includes protocol identifiers which differentiate the protocols from one another, and message identifiers which differentiate the service capability features from one another, and wherein the service capability features have different ranges of the message identifier.

2. The system of claim 1, wherein the protocol stack comprises:

one or more units maintaining various types of protocols;

a first unit performing data connection, and transmitting and processing a message; and

a second unit managing the various types of protocols,

wherein the protocol identifiers and the message identifiers are stored in the second unit managing the various types of protocols.

3. The system of claim 2, wherein the protocol stack is an SS No. 7 protocol stack,

the first unit performing data connection, and transmitting and processing messages is a message transfer part, and

the second unit managing the various types of protocols is a signal connection control part.

4. The system of claim 1, wherein the protocol identifiers are subsystem numbers, and

the message identifiers of different ranges are allocated to the service capability features.

5. The system of claim 4, wherein the protocol messages are distributed to corresponding the unit maintaining protocols using the subsystem numbers, and

the service capability features are detected and distributed using the corresponding message identifiers.

6. 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.

7. The method of claim 6, wherein in the step (a), when a service request is a new session, a corresponding message identifier to the service capability feature is allocated.

8. The method of claim 6, wherein the ranges of message identifiers allocated to the service capability features are different from one another.

9. The method of claim 6, wherein the protocol identifier is a number of sub-system which maintains the corresponding protocol.

10. A computer recording medium having embodied thereon a computer program for the method of claim 6.

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

(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.

12. The method of claim 11, wherein if it is determined in the step (d) that the protocol message includes the message identifier, the protocol message is provided to a network event processing service capability feature.

13. The method of claim 11, wherein the protocol identifier is a number of sub-system which maintains the corresponding protocol.
