  • 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.
