Chapter 6 Command Definitions
6.12.9 SGRKI – Signaling Gateway Routing Key Initiate
Synopsis
This command initiates a routing key or partial routing key to determine a destination identifier. The
destination identifier is then used to select the outgoing destination. The Signaling Gateway compares the
routing keys with a data message in an attempt to find a data match. If a match is found, the destination
identifier is then used to select a route to an eventual destination.
The user can define a number of different tables of routing keys. In the routing model, the incoming route
identifies which routing table to use.
Apart from the routing key index and routing key table, the routing key elements are optional and can be
wildcarded with a null string.
A routing key is defined as a combination of NC // NI / SI / OPC / DPC / BCIC / RANGE .
For DPC , OPC , NI , SI , NC , BCIC and RANGE , a value of “null” is supported. “null” indicates a wildcard value
and means any value. “null” is the default value for a routing key entry.
Note: The value “null” cannot be used for these parameters elsewhere in the system unless explicitly
specified in the command.
Syntax
SGRKI: RKI =, RKTAB =,[ NC =,][ OPC =,][ NI =,][ SI =,][ DPC =,][ RANGE =, BCIC =,] DEST =;
Prerequisites
•
The routing key ID has not already been specified.
•
The routing key combination has not already been specified nor does it form a superset or subset of an
existing routing key.
Note: This check takes into account one or more routing elements marked as a wild card.
•
The destination ID has already been initiated.
•
If SI is set to SCCP, the BCIC / RANGE parameters cannot be specified.
•
If one of BCIC / RANGE are specified, the other must be specified.
•
For circuit related keys, the CIC ranges specified for an NC / OPC / NI / DPC combination must not overlap
existing ranges for that combination.
•
If an OPC or DPC are specified, the NC cannot be wildcarded.
•
BCIC cannot be negative.
•
If the routing key has a destination to an AS , the NC / DPC parameters are required and must match with
the AS NC/DPC.
