SS7 Sample Configuration Files

This section shows the sample configuration files for creating the basic SS7 connection to an HLR. These sample files show how to set up one board with two SS7 links.

NA — INT
DIG — Enter the first digits of MSISDN/IMSI. The routing decision is made with "best match" method. The PC message is sent towards this Point Code if "digit" matches the item specified as NP (ISDN-Tel).
Point codes — in decimal format.

Sample authGateway Command and File

sampleCreateProcess.mml

CRTE-PROCESS:NAME="GMT",CE="as1",EXEC="authGateway -name GMT -port 2000 -host as1 -node MGW -prot C7 
-conf conf/authGateway.conf.100 -lri 1 -lssn 7 -appctx 3 -ldigits 358402114300"; 
START-PROCESS:NAME="GMT", CE="as1";

authGateway.conf (Gateway Routing Configuration File)

Each line of this configuration file describes:

• The parameters used to form the destination SCCP address.
• The decimal value of the bearer service (bs) and/or teleservices (ts) indicating an authorization.
• A string associated with each bs or ts value. If no bs and no ts are specified, no authorization is performed by the authGateway.

For each request, the first digits of the IMSI are compared with odigits. The first line of the configuration file that matches is selected for the current request. If the routing indicator (rri) specifies that the routing is done on GT, the leading digits are replaced with the new digits (ndigits) to perform the numbering plan translation. If a parameter is not present on the line, it is not present in the SCCP destination address. If this is incompatible with the routing indicator, an error message is issued when the MAP authentication Gateway is started.

After modifying this configuration file, the authGateway has to be restarted. Modification of the ndigits value may require the creation of a new GT rule (CREATE-GT command).

 bs dec:string
 If the specified bearer service exists in HLR SIM-profile, then string is returned for further processing (see ProfileMap in simauth.aut).


 ts

 ts dec:string
 If the specified teleservice exists in HLR SIM-profile, then string is returned for further processing (see ProfileMap in simauth.aut).



 

Sample smsGateway Commands and Files

CREATE-PROCESS:NAME="SMS", CE="as1", EXEC="smsGateway -name SMS -port 2004 -host as1 -node MGW -conf 
conf/smsGateway.conf.100 -smsc 1935840123456 -appctx 3 -invktimeout 180"; 

START-PROCESS:NAME="SMS", CE="as1";

Table 51: Parameters Used in Create and Start Commands 

Parameter	Description
name	Process name
port	Remote port specified in smsulcmmg.conf
host	Hostname
node	Node name (used in swmml command)
smsc	GT number of SMSC
appctx	MAP version (2 or 3) to be used
invktimeout	Timeout for sending SMS
NAME	Process name
CE	Hostname (CE means computing element)
EXEC	Program to be executed

smsGateway.conf

This configuration file describes the parameters used to form the destination SCCP address.

• One line containing DestAdress is used to address the destination node (HLR, MSC or SGSN). It is used only for SEND_ROUTING_INFO_FOR_SM in case of a Mobile Terminated SMS or to obtain the IMSI from the subscriber's MSISDN.
• The digits to address the HLR (that is, subscriber's MSISDN) are obtained from the client library.
• The digits to address the serving MSC (or SGSN) are obtained as a result of the SEND_ROUTING_INFO_FOR_SM message.
• If a parameter is not present on the line, it will not be present in the SCCP destination address. If this is incompatible with the routing indicator, an error message will be issued when the SMS Gateway is started.
• An optional parameter rssn, can be used to specify the destination ssn. This parameter will be used for routing only if the message is routed with a GT rule configured with SSN=DEF. If a normal GT is used (SSN=value), the value will overwrite the rssn defined in this file.
• All RoutingInfo messages are sent by default to SSN 6 (HLR).

The smsGateway has to be restarted after it is modified. Modification of the digits value may require the creation of a new GT rule (CREATE-GT command).

Example:

DestAddress rssn 8 rnai 4 rnp 1 rgti 4 rtt 0 rri 0
