SMS MO (Short Message Service Mobile Originating) - Routing

configuration in Ericsson MSC

SMS sending bypassing SCAddress in MS (Mobile Station)

ObjectivesThis document is an answer to

customer request to make possible the sending of SMS’s directly to a destination without going through SMS-SC configured in MS.

Example: SMS delivery to a Tele-Voting machine.

ReferencesCheck in ALEX, MSC Feature:

Destination Based Routing (DBR) of a Mobile Originating (MO) Short Message Service (SMS)

Configuration

MGDRI:DANUM=80555, NSCADDR=966yyyyyyyyy; 

DANUM=danum : This parameter specifies, in numerical format, the address digits of the Transfer Protocol destination Address TP-DA of the MO-SM (B-number).NSCADDR=nscaddr : New SC address to be used for the routing of the MO-SMS. In our case Tele-voting address is

966yyyyyyyyy

Configuration

The syntax of the command can include other parameters i.e. SCADDR. In our case since all SMS’s will be routed to same address, this parameter is not included.

ConfigurationDANUM can be given in: Numerical format with:

◦ 1. Address digits in a value range 0-9 or #10-#15 Note:   # means hexadecimal digits

◦ 2. TON with values 0-4, 6-7. Note:   Value 5 is restricted since it implies alphanumeric format

◦ 3. NAPI with allowed values 0-15 Alphanumerical format with :

◦ 1. Address digits containing characters coded according to GSM 7-bit default alphabet

◦ 2. TON value 5 (automatically associated)

◦ 3. NAPI value 0 (automatically associated)

ConfigurationParameter DescriptionNAPI Numbering Plan Indicator

Test of functionality

This test case is showing that SMS delivery, to a e.g. Tele-Voting machine, is going directly, and NOT first to the SMS-SC configured in MS.

1. Check Subscriber categories for MS(msisdn) in HLR

Command: HGSDP:MSISDN=msisdn,SSDA;

Result:HLR SUBSCRIBER DATAPERMANENT SUBSCRIBER DATASUPPLEMENTARY SERVICE DATA

2. Assign if missing TS22 (SM-MO) in HLR

Command: HGSDC:MSISDN= msisdn, SUD=TS22-1;

Result: EXECUTED

4. Perform a LOCATION UPDATE for MS1 in MSC and verify

Command: MGSLP:IMSI=imsi;Result: Printout MT MOBILE

SUBSCRIBER LISTCheck: Check that MS is

registered successfully in MSC and has state IDLE

Test of functionality

5. Define SC ADDRESS of the general SMS-SC in MS.

6. Action: Perform MO SMS operation to the Tele-Voting machine

Result: The SMS is routed directly to the Tele-Voting machine, defined as new SC-address in MSC.
