  • Patent number: 6078584
    Abstract: In order to relieve the loading of a service control point SCP in a telecommunications signalling network, query messages addressed to the SCP are intercepted prior to receipt by the SCP. These intercepted query messages are examined and response data generated, at least for certain query types. For a query message for which response data is generated, the query message is replaced by a response message addressed to the querying entity. The response message is then forwarded on in the same sense as the received query message. In a preferred implementation, the forwarded response message will next be received by a signalling transfer point STP and be directed back to the querying entity.

  • Patent number: 5949871
    Abstract: A method of providing a service, such as local number portability (LNP), in a switched telecommunications system, in which a message interceptor is disposed in a signalling link of an SS7 signalling network of the system. The message interceptor detects calls for which service implementation is required, by comparing the content of intercepted circuit-related SS7 messages with service trigger conditions, such as message type (checked directly by the interceptor) and message content (e.g. called number, which the interceptor checks by reference to a database). When service implementation is detected as being required, the message interceptor may implement at least part of the required service by modifying parameters of the intercepted message; alternatively, the interceptor may re-direct the message to a service control function for service implementation.

  • Patent number: 5940492
    Abstract: A method is disclosed that avoids the need to enlarge the translation tables held by Signal Transfer Points (STPs), for the purpose of effecting global title routing of certain signalling messages to enable number portability. Signalling links are monitored to detect messages needing to be routed by global title; the global title of each such message is then checked to see if it relates to a ported number and if this is the case, the global title is modified to a number that will result in the appropriate routing of the message on the basis of the existing translation tables of the STPs.

  • Patent number: 5905724
    Abstract: A programmable message substitution unit PMSU (60) is provided for modifying signalling messages passing across a link (61) of a telecommunications signalling network without disrupting the link-level procedures operating over the link. In the event of a power failure or upon the detection of an operational anomaly, a bypass relay arrangement (65) is used to bypass the PMSU (60). The PMSU (60) comprises a substitution block for modifying selected messages, a database block for doing database lookups to ascertain new message parameter values to be substituted for existing ones, and a supervision block for checking the operation of the substitution block. The PMSU may be used to implement local number portability or other services.
