|Publication Date:||1 April 2021|
The present document defines the Diameter-based interfaces specific to SMS when they are used in conjunction with the "SMS in MME" architecture specified in 3GPP TS 23.272  or for SGSN supporting EPS interfaces, or the" SMS in 5GS" architecture specified in 3GPP TS 23.501 . It comprises:
- the Diameter application for the S6c interface between the HSS/UDM and the central SMS functions (SMS-GMSC, SMS Router) ;
- the Diameter application
- for the SGd interface between the MME/SMSF, the SMS-IWMSC, the SMS-GMSC and the SMS Router.
- for the Gdd interface between the SGSN, the SMS-IWMSC, the SMS-GMSC and the SMS Router.
For the purpose of supporting SMS in 5GS, the UDM may implement the requirements specified in the present specification for HSS, with the following modification:
- "HSS" is to be replaced with "UDM".
