23.2.4 Procedure in the SMS Interworking MSC (SMS-IWMSC)

29.0023GPPMobile Application Part (MAP) specificationRelease 17TS

This procedure applies only when the SMS-IWMSC is not integrated with the serving MSC or SGSN.

The process starts when the SMS-IWMSC receives a dialogue opening request with the application context shortMsgMO-RelayContext. The MAP process invokes macros not defined in this clause; the definitions of these macros can be found as follows:

Receive_Open_Ind see clause 25.1.1;

Check_Indication see clause 25.2.1.

Sheet 1:The decision box "TCAP Handshake required" takes the "yes" or "no" exit depending on agreements between the SMS-IWMSC’s operator and the serving node’s operator (see 3GPP TS 33.204 [34a]).

The mobile originated short message service transfer process in the SMS-IWMSC is shown in figure 23.2/5.
