Signaling gateway
First Claim
Patent Images
1. A signaling gateway for passing messages from a first network to an application server process provided on a second network, the messages comprising a transaction identifier, whereinthe transaction identifier comprising a set of bits utilized by a transmission protocol, and a set of remaining bits comprising a part;
- the signaling gateway is configured to receive an initial message from a calling entity and read the transaction identifier within the initial message,to identify the application server process from the part of the transaction identifier,to forward the initial message to the application server process,to receive a continuation message from the application server process, in response to the application server process receiving the initial message, the continuation message including the transaction identifier,to modify the transaction identifier within the continuation message as a modified transaction identifier, andto forward the continuation message to the calling entity,wherein the modified transaction identifier includes at least a part identifying the application server process and a further part identifying an application server prior to forwarding the continuation message to the calling entity, and the set of remaining bits of the transaction identifier comprises the part and the further part.

1. A signaling gateway for passing messages from a first network to an application server process provided on a second network, the messages comprising a transaction identifier, wherein
the transaction identifier comprising a set of bits utilized by a transmission protocol, and a set of remaining bits comprising a part; -
the signaling gateway is configured to receive an initial message from a calling entity and read the transaction identifier within the initial message, to identify the application server process from the part of the transaction identifier, to forward the initial message to the application server process, to receive a continuation message from the application server process, in response to the application server process receiving the initial message, the continuation message including the transaction identifier, to modify the transaction identifier within the continuation message as a modified transaction identifier, and to forward the continuation message to the calling entity, wherein the modified transaction identifier includes at least a part identifying the application server process and a further part identifying an application server prior to forwarding the continuation message to the calling entity, and the set of remaining bits of the transaction identifier comprises the part and the further part. - View Dependent Claims (2, 3, 4, 5, 6)

7. An application server configured to
receive an initial message from a calling entity forwarded by a signaling gateway, to generate a continuation message, in response to receiving the initial message, the continuation message including a transaction identifier comprised of a set of bits utilized by a transmission protocol to modify the transaction identifier within the continuation message as a modified transaction identifier, wherein the modified transaction identifier includes a set of remaining bits comprising at least a part identifying an application server process and a further part identifying the application server, and to forward the continuation message to the signaling gateway.

8. A method of passing messages from a first network to an application server process provided on a second network, the messages comprising a transaction identifier comprised of a set of bits utilized by a transmission protocol and a set of remaining bits including a part, comprising the steps of:
-
receiving by a signaling gateway an initial message from a calling entity and reading the transaction identifier within the initial message, identifying by the signaling gateway the application server process from the part of the transaction identifier; forwarding by the signaling gateway the message to the application server process; receiving by the signaling gateway a continuation message from the application server process, in response to the application server process receiving the initial message, the continuation message including the transaction identifier; to modify the transaction identifier within the continuation message as a modified transaction identifier; and forwarding by the signaling gateway the continuation message to the calling entity, wherein the modified transaction identifier includes at least a part identifying the application server process and a further part identifying an application server prior to forwarding the continuation message to the calling entity, and the set of remaining bits of the transaction identifier comprises the part and the further part. - View Dependent Claims (9)
