Abstract

A method of routing a message is described, comprising: receiving a message indicating an operation to be performed by a destination node; determining an address of the destination node by consulting a local database indicating the address of the destination node; initiating a dialogue with the destination node; and sending a message indicating the operation to the destination node.

Claims

1. A signalling method for routing a signalling message, the method comprising the steps of:

exchanging signalling messages with an originating network entity comprising a receiving a first signalling message comprising a requested service;

determining an address of a destination network entity by consulting a database comprising the address of the destination node;

exchanging signalling messages with the destination network entity;

the exchanging comprising initiating a signalling dialogue with the destination network entity and sending a second signalling message comprising an indication of the requested service to the destination network entity.

2. A method as claimed in claim 1 in which consulting the database comprises requesting the address from at least one of a process and a thread, the at least one of a local process and a local thread having access to the database, and receiving the address from the at least one of the local process and the local thread.

3. A method as claimed in claim 2, wherein the at least one of the process and the thread performs the steps of initiating the dialogue with the destination network entity and sending the signalling message to the destination network entity.

4. A method as claimed in any preceding claim in which exchanging signalling messages with an originating network entity comprising a receiving a first signalling message comprising a requested service comprises the steps of:

receiving, from the originating network entity, a dialogue begin message to initiate a dialogue with the originating node; and

acknowledging the begin message to initiate the dialogue.

5. A method as claimed in claim 4 in which consulting the database comprises forwarding the dialogue begin message to at least one of a process and a thread, the at least one of a local process and a local thread having access to the database, and receiving the address from the at least one of the process and the thread.

6. A method as claimed in any preceding claim comprising storing a context for identifying further messages associated with the first signalling message, wherein the context comprises at least one of an application context, a calling party address, a called party address, an originating transaction ID and a destination transaction ID.

7. A method as claimed in any preceding claim in which receiving the first signalling message comprising a requested service comprises receiving a message comprising a mobile application part (MAP) indicating the operation.

8. A method as claimed in any preceding claim in which sending the second signalling message comprising the indication of the requested service to the destination network entity comprises forwarding the message including the mobile application part (MAP) indicating the operation to the destination network entity.

9. A method as claimed in any preceding claim in which the database is a local database.

10. A signalling system for routing signalling messages comprising means to implement a method as claimed in any preceding claim.

11. A computer program comprising computer executable instructions for implementing a system or method as claimed in any preceding claim.
