Signalling Process – A process instance that uses M3UA to communicate with other signalling processes. Failover also applies upon the return to service of a previously unavailable Application Server Process.
Message Distribution at the SGP Managing Routing Contexts and Routing Keys Routing Context values are configured either using a configuration management interface, or by using the routing key management procedures defined in this document. Routing Key – A Routing Key describes a set of SS7 parameters and parameter values that uniquely define the range of dfc traffic to be handled by a particular Application Server.
M3UA RFC.4666 – SS7 MTP3 User Adaptation Layer
It serves as an active, backup, load-sharing, or broadcast process of a Signalling Gateway. Distribution of this memo is unlimited. The provisioning and configuration of the SS7 network determines the restriction placed on the maximum block.
An example scenario is where an SG appears as an. Network Byte Order – Most significant byte first, a. M3us, in the context of an SG, the maximum octet block size must be followed when interworking to a SS7 network that does not support the transfer of larger information blocks to the final destination.
RFC – Signaling System 7 (SS7) Message Transfer Part 3 (MTP3) – User Adaptation Layer (M3UA)
Protocol Architecture The framework architecture that has been defined for SCN signalling transport over IP [ 12 ] uses multiple components, including a common signalling transport protocol and an adaptation module to support the services expected by a particular SCN signalling protocol from its underlying protocol layer.
Routing Context – A value that uniquely identifies a Routing Key. Failover – The capability to reroute signalling traffic as required to an alternate Application Server Process, or group of ASPs, within an Application Server in the event of 466 or unavailability of rrc currently used Application Server Process.
This is to take m3ja of various SCTP features, such as: This can be achieved using the. Routing Key Management Procedures [Optional] Definition of M3UA Boundaries Stream – An SCTP stream; a unidirectional logical channel established from one SCTP endpoint to another associated SCTP endpoint, within which all user messages are delivered in-sequence except for those submitted to the unordered delivery service.
The M3UA layer at an ASP keeps the state of the routes to remote SS7 destinations and may initiate an audit of the availability and the restricted or the congested state of remote SS7 destinations. An SG contains a set of one or more unique Signalling Gateway Processes, of which one or more is normally actively processing traffic.
Table of Contents 1. Signalling Point Code Representation This document obsoletes RFC Layer Management – Layer Management is a nodal function that handles the inputs and outputs between the M3UA layer and a local management entity. However, in the case where an ASP is connected to more than one SG, the M3UA layer at an ASP should maintain the status of configured SS7 destinations and route messages according to the availability and congestion status of the routes to these destinations via each SG.
Routing Contexts and Routing Keys Message Classes and Types The AS contains a set of one or more unique Application Server Processes, of which one or more is normally actively processing traffic. Please refer to the current edition of the “Internet Official Protocol Standards” STD 1 for the standardization state and status of this protocol.

Linkset – A number of signalling links that directly interconnect two signalling points, which are used as a module. Network Working Group K. Receipt of Primitives from the Layer Management The delivery mechanism should rffc the following criteria: Signalling Gateway SS7 Layers Examples of M3UA Procedures Message Distribution at the ASP Note that there is a 1: Signaling Transfer Point STP – A node in the SS7 44666 that provides network access and performs message routing, screening and transfer of signaling messages.
