摘要:
According to one embodiment of present invention, there is provided a method of controlling access to a communication network. The method includes receiving a request from a communication device to connect to the communication network, the request including a substantially unique identifier of the device, and determining whether the identifier is contained in a local device database of the network. Where it is determined that the identifier is not contained in the local database, the method further includes authorizing the device to connect to the network, and at a subsequent update of the local device database, determining the status of the identifier from a shared device database, and updating the status of the determined identifier in the local device database with the determined status.

According to one embodiment of the present invention, there is provided a method, in a communication network, of associating a subscriber directory identifier to a first subscriber identifier. The method comprises receiving a request to connect a communication device to the network, the request including a subscriber identifier derived from the first subscriber identifier, determining the first subscriber identifier from the received subscriber identifier, and associating a subscriber directory identifier with the determined subscriber identifier.

Methods and related apparatus are described of operating a transaction proxy to act as a conduit for a structured transaction, such as TCAP structured dialog between a first transaction peer, for instance an SMSC, and a second transaction peer, for instance an MSC. The method comprises the steps of: receiving a begin message; determining an address of the first transaction peer from the begin message; responding to the begin message by sending a continue message to the first transaction peer; and, if no abort message is received from the first transaction peer, forwarding the begin message to the second transaction peer. Embodiments of the invention employ the techniques for filtering mt-forwardSM messages containing spoofed addresses in GSM systems,

One embodiment of a method for operating a signaling gateway process determines routing information enabling an application server process to discriminate a signaling message and makes the routing information available to the application server process together with the signaling message payload.
摘要:
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.
摘要:
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.
摘要:
A signalling gateway for connecting a first network to a second network, the signalling gateway being operable to store a plurality of routing keys, wherein at least one of the routing keys comprises monitoring destination information associated with a monitoring entity, the signalling gateway being operable to, receive a message via the first network, the message comprising message destination information identifying a recipient entity, compare the destination information and the routing key and, when the message destination information matches the monitoring destination information, transmit the message to the monitoring entity on the second network.

摘要:
A routing element passes messages between an application server and a plurality of signalling gateways. The routing element is operable to receive a message comprising routing information from one of the application server and a one of the signalling gateways and forward the message to the other of the application server and the one of the signalling gateways in accordance with the routing information
