B.3 Client registration

33.1803GPPRelease 17Security of the Mission Critical (MC) serviceTS

Before a client can obtain ID tokens and access tokens (required to access MCX resource servers) it shall first be registered with the IdM server of the service provider as required by OpenID Connect 1.0. The method by which this is done is not specified by this profile. For native clients, the following information shall be registered:

– The client is issued a client identifier. The client identifier represents the client’s registration with the authorization server, and enables the IdM server to reference parameters associated with that client’s registration when being requested for an access token by the client.

– Registration of the client’s redirect URIs.

Other information about the client such as (for example): application name, website, description, logo image, legal terms to be consented to, may optionally be registered.
