  • Methods and systems for providing database node access control functionality in a communications network routing node
    Patent number: 7564870
    Abstract: A network element provides service control point or database node front end processing functionality, as well as routing functionality for routing data packets through a network. The network element includes a first communication module for receiving data packets from a first communication network. A second communication module transmits data packets over a second communications network. A database access control (DAC) process queries a DAC database and modifies received packets to include information returned by the database lookup.

  • Method and apparatus for signal mediation in a common channel signaling network
    Patent number: 6167129
    Abstract: A method and apparatus for signal mediation in a common channel signaling network are described. The method involves identifying candidate message signal units that require mediation and transmitting the candidate signal unit to an associated mediation function which performs access mediation on the contents of the candidate signal unit. The access mediation function may return one or more data packets to the network. The apparatus includes the signal transfer point, the associated mediation function and enhanced functionality in the signal transfer point for screening candidate signal units. The advantage is a more flexible and easily managed signal mediation point that removes the bulk of signal mediation from the signal transfer point so that the signal transfer point can remain dedicated to its signal transfer function.

  • Method and system for providing mediated access between signaling networks
    Patent number: 5953404
    Abstract: A method and system is disclosed for mediating signalling protocol dialogue between an internal signalling network operational domain operated by one network operator and an external signalling network operational domain operated by another network operator. One embodiment provides a method of dividing the SS7 traffic (Message Signal Units or MSUs) arriving for Mediation, into classes such that network performance requirements can be met, wherein some message classes will receive only normal SS7 processing while others will be analyzed in detail. MSUs requiring detailed analysis must be routed to a mediation application process appropriate to that class. Another embodiment provides a method of manipulating Signalling Connection Control Part (SCCP) address parameters in the SMP in order to maintain normal SS7 message processing and routing functions while mediating individual messages.
