MTP 3 User Adaptation (M3UA) - SIGTRAN Stack
M3UA is a protocol for supporting the transport of any SS7 MTP3-User signaling (e.g., ISUP and SCCP messages) over IP using the services of the Stream Control Transmission Protocol (SCTP). In addition, provision is made for protocol elements that enable a seamless operation of the MTP3-User peers in the SS7 and IP domains. This protocol would be used between a Signaling Gateway (SG) and a Media Gateway Controller (MGC) or IP-resident Database. SG: SG is a Signaling Agent, which interface between the SS7 and IP network. It appears the SS7 SP to the SS7 . SG is logical entity with contains the one of more SGP. SGP: SGP is logical instance of SG. SGP is a physical entity, which has the association between to ASP. All SGP within the SG have the view towards the SS7 Network. AS: AS is a logical entity, which serves as a specific Routing key. It is present in IP domain. An AS contains set of one or more ASP. There is 1:1 mapping of AS to r...
