A method for routing short messages using a router in a mobile telecommunications network. The method comprises: receiving a short message from a short message element; attempting to deliver a short message without passing through a store and forward function; and if said attempted delivery fails, directing said short message using a mobile originated procedure to a short message service center having a store and forward function.

Method and apparatus for routing short messages in mobile telephone networks

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, the signaling gateway being operable to receive a message and read the transaction identifier, identify the application server process from a part of the transaction identifier and forward the message to the application server process.

Signaling gateway

Embodiments of the present invention relate to a communication arrangement for distinguishing between network entities having the same address by translating between the same addresses and surrogate addresses using an intermediary network entity.

Communication system and method

A method of providing a routing key interpreter for a signalling gateway, the method comprising the steps of generating an input file comprising a plurality of input expressions and a plurality of routing keys corresponding to the input expression, supplying the input file to a lexical analyser generator to generate a lexical analyser, and implementing the routing key interpreter using the lexical analyser.

Routing key interpreter

A method is described for operating a gateway to act as a conduit for a structured transaction between a first transaction peer and a second transaction peer, the structured transaction having at least a begin message for opening a logical communication path, a continue message for maintaining a logical communication path and an end message for closing a logical communication path. The method comprises the steps of: receiving a first begin message from the first transaction peer; receiving from the first transaction peer a continue message having a request element; determining a routing key identifying the second transaction peer from the continue message; constructing and sending a second begin message, including the component, to the second transaction peer; receiving a first end message including a response element from the second transaction peer; constructing and sending a second end message including the response element to the first transaction peer. In described embodiments, the gateway is a signalling gateway linking an SS7 network and an IP network and the structured transaction is a TCAP structured dialogue.

Methods and related apparatus for operating a gateway to act as a conduit for a structured transaction

A method is described for operating a signalling gateway comprising determining information enabling an application server to identify a signalling gateway process to which to direct a message destined for a particular point code and making said information available to the application server. In preferred embodiments, the information takes the form of a routing table that serves to distribute signalling gateway process identifiers over possible SLS values by, for instance, mapping process instance identifiers to possible SLS values for messages sent by the application server. By allowing the application server processes the possibility to determine to which signalling gateway process each message should be directed, retransmission of messages within the signalling gateway can be avoided.
