1  Scope  p. 7

This 3GPP Technical Specification (TS) specifies:
  1. The interactions between the HSS (Home Subscriber Server) and the SIP AS (Application Server) and between the HSS and the OSA SCS (Service Capability Server). This interface is referred to as the Sh reference point.
  2. The interactions between the SIP AS and the SLF (Subscription Locator Function) and between the OSA SCS and the SLF. This interface is referred to as the Dh reference point.
The IP Multimedia (IM) Core Network Subsystem stage 2 is specified in TS 23.228 and the signalling flows for the IP multimedia call control based on SIP and SDP are specified in TS 24.228.
The IP Multimedia (IM) Session Handling with the IP Multimedia (IM) call model is specified in TS 23.218.
This document addresses the signalling flows and message contents for the protocol at the Sh and Dh interface.
This document also addresses how the functionality of Ph interface is accomplished.
The Presence Service Stage 2 description (architecture and functional solution) is specified in TS 23.141.

3.1  Definitions  p. 9

For the purposes of the present document, the following terms and definitions apply.
IP Multimedia session:
IP Multimedia session and IP Multimedia call are treated as equivalent in this specification.
Transparent data:
Data that is understood syntactically but not semantically by the HSS. It is data that an AS may store in the HSS to support its service logic. One example is data that an AS stores in the HSS, using it as a repository.
Non-transparent data:
Data that is understood both syntactically and semantically by the HSS.
AS (Application Server):
a term used to denote either of a SIP Application Server or an OSA Service Capability Server.

4  Main Concept  p. 9

This document presents the Sh interface related functional requirements of the communicating entities.
It gives a functional classification of the procedures and describes the procedures and message parameters.
Error handling flows, protocol version identification, etc. procedures are also included.

5  General Architecture  p. 10

This clause further specifies the architectural assumptions associated with the Sh reference point, building on TS 23.228, TS 23.218 and also the Ph reference point building upon TS 23.141.

5.1  Functional requirements of network entities  p. 10

5.1.1  Functional Requirements of the Application Server  p. 10

The Application Server may communicate with the HSS over the Sh interface.
For functionality of the Application Server refer to TS 23.002, TS 23.228 and TS 23.218.

5.1.2  Functional requirements of HSS  p. 10

The HSS may communicate with the Application Server over the Sh interface and with the Presence Network Agent over the Ph interface. The functionality of the Ph interface shall be the same as the functionality of the Sh interface.
For functionality of the HSS refer to TS 23.002, TS 23.228 and TS 23.218.

5.1.3  Functional Requirements of the Presence Network Agent |R6|  p. 10

The Presence Network Agent may communicate with the HSS over the Ph interface. In this case, all references to an Application Server in this specification apply also to a Presence Network Agent.

5.2  Functional classification of Sh interface procedures  p. 10

Operations on the Sh interface are classified in functional groups:
  1. Data handling procedures
    • The download of data from the HSS to an AS.
    • The update of data in the HSS.
  2. Subscription/notification procedures
    • An AS can subscribe to receive notifications from the HSS of changes in data.
    • The HSS can notify an AS of changes in data for which the AS previously had subscribed.
