ETSI ETSI TS 124 482 V15.0.0 (2018-06)53GPP TS 24.482 version 15.0.0 Release 151 Scope This document specifies the id
24、entity management and authentication protocols needed to support Mission Critical Services (MCSs). Identity management applies only to on-network operation. MCSs are services that require preferential handling compared to normal telecommunication services, e.g. in support of police or fire brigade.
25、MCSs can be used for public safety applications and also for general commercial applications (e.g., utility companies and railways). This document is applicable to User Equipment (UE) supporting the identity management client functionality, and to application servers supporting the identity manageme
26、nt server functionality. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. - References are either specific (identified by date of publication, edition number, version number, etc.) or non-specific. - For a s

41、MC services is shown in figure 4.1-1 below and consists of the identity management server located in the common services core and the identity management client located in the MC UE. The IdM server and the IdM client in the MC UE establish the foundation for MC services user authentication and user
42、authorisation. Figure 4.1-1: Functional model for MC services identity management The CSC-1 reference point, between the IdM client in the UE and the Identity Management server, provides the interface for user authentication. CSC-1 supports OpenID Connect Core 1.0 6 and IETF RFC 6749 5. The OpenID C
43、onnect profile for MC services is implemented as described in 3GPP TS 33.180 17. The MC services user authentication, the MC services user authorisation, the OpenID Connect Core 1.0 6 and the OpenID Connect profile described in 3GPP TS 33.180 17 for MC services forms the basis of the MC services ide
44、ntity management architecture. Subclause 6.2.1 and subclause 6.3.1 describes the procedures for the MC services user authentication. OIDC is flexible with respect to the user authentication mechanism used. As 3GPP TS 33.180 17 has indicated that username and password authentication is mandatory to s
45、upport, that mechanism is included in subclause 6.2.1 and subclause 6.3.1, although other mechanisms are possible. When the MC services user is authenticated, the procedure will provide an id token, an access token and a refresh token, which are all described in 3GPP TS 33.180 17. The access token i
46、s scoped to the services the MC services user is authorised for, e.g., group management services, key management services and MC services. The access token will be utilized for MCPTT service authorisation, MCData service authorisation and MCVideo service authorisation as documented in 3GPP TS 24.379
47、 12, 3GPP TS 24.282 22 and 3GPP TS 24.281 21 respectively. After an MC service user has obtained an access token from their home IdM server, they can acquire a security token from their home IdM server by means of the procedures of subclause 6.2.2, subclause 6.3.2. The security token can be used to
48、acquire an access token from the IdM server of a partner system to allow access to resources in the partner systems domain by means of the procedures of subclause 6.2.3 and subclause 6.3.3.
