M3UA RFC.4666 – SS7 MTP3 User Adaptation Layer
However, 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 466 information blocks to the final destination. The AS contains a set of one or more unique Application Server Processes, of which one or more is normally actively processing traffic. Routing Key Management Procedures [Optional] Distribution of this memo is unlimited.
Note that there is ,3ua 1: 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. Linkset – A number of signalling links that directly interconnect two signalling points, which are used as a module.

Routing Key – A Routing Key describes a set of SS7 parameters and parameter values that uniquely define the range of signalling traffic to be handled by a particular Application Server. Signalling Gateway SS7 Layers 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.
Routing Contexts and Routing Keys 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.
Message Distribution at the ASP This is to take advantage of various SCTP features, such as: This can be achieved using the. 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.
Network Byte Order – Most significant byte first, a.
This document obsoletes RFC Signalling Point Code Representation Message Classes and Types Table of Contents 1. It serves as an active, backup, load-sharing, or broadcast process of a Signalling Gateway.
RFC – part 1 of 5
The delivery mechanism should meet the following criteria: Examples of M3UA Procedures Please refer to the current m3uw of the “Internet Official Protocol Standards” STD 1 for the standardization state and status of this protocol. Definition of M3UA Boundaries Routing Context – A value that uniquely identifies a Routing Key.
Signaling Transfer Point STP – A node in the SS7 network that provides network access and performs message routing, screening and transfer of signaling messages. Routing Context values are configured either using a configuration management interface, or by using rfd routing key management procedures defined in this document. Message Distribution at the SGP An example scenario is where an SG appears as an.
Managing Routing Contexts and Routing Keys Receipt of Primitives from the Layer Management However, in the case where an ASP is connected to m3uw 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.
