Signaling Transfer Point STP – A node in the SS7 network that provides network access and performs message routing, screening and transfer of signaling messages. If the Unexpected message contained. Receipt of Primitives from the Layer Management The “Unsupported Message Type” error is sent if a message with an unexpected or unsupported Message Type is received.

The “Missing Parameter” error would be sent if a mandatory parameter were not included in a message. The “Parameter Field Error” would be sent if a message is received with a parameter having a wrong length field.

rfx 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. Please refer to the current edition of the “Internet Official Protocol Standards” STD 1 for the standardization state and status of this protocol. The format of rfv Traffic Mode Type Identifier is as follows: Note that there is a 1: This document obsoletes RFC An SG contains a set of one or more unique Signalling Gateway Processes, of which one or more is normally actively processing traffic.


Signalling Gateway SS7 Layers For example, the message type might be unexpected given the current state, or a parameter value might be invalid.

The “Unsupported Message Class” error is sent if a message with an unexpected or unsupported Message Class is received. The “No Configured AS for ASP” error is sent rff a message is received from a peer without a Routing Context parameter and it is not known by configuration data which Application Servers are referenced.

Routing Key Management Procedures [Optional] The “Unexpected Message” error MAY be sent if a defined and recognized message is received that is not expected in the current state in some cases, the ASP may optionally silently discard the message and not send an Error message. For an alias point code configuration, the DPC parameter would be repeated for each point code.

The receiving end responds with an Error message, indicating the version the receiving node supports, and notifies layer management.

The receiver of a BEAT message does not process this field, as it is only of significance to the sender. The ASP Up message contains the following parameters: Network Working Group K. An example scenario is where an SG appears as an. This is used to allow the registration of multiple Routing Keys in a single message.

For this error, the Diagnostic Information parameter MUST be included with the first 40 octets of the offending message. The value reflects the new state of the Application Server. 46666 format for the ASP Inactive message parameters is as follows: A Diagnostic Information parameter with a zero length 44666 is not considered an error this means that the Length field in the TLV will be set to 4.


The delivery mechanism should meet the following criteria: The format for the BEAT message is as follows: This can be achieved using the.

The format rf each result is as follows: The Routing Key parameter may be present multiple times in the same message. Failover – The capability to reroute signalling traffic as required to an alternate Application Server Process, or group of ASPs, within rtc Application Server in the event of failure or unavailability of a currently used Application Server Process.

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.

However, in the context of an 6466, the maximum octet block size must be followed when interworking to a SS7 network that does not rvc the transfer of larger information blocks to the final destination. The ASP Active message contains the following parameters: Failover also applies upon the return to service of a previously unavailable Application Server Process.

The sender of this message expects that the receiver of this message will create a Routing Key entry and assign a unique Routing Context value to it, if the Routing Key entry does not already exist.
