7  Security, authorization and privacy  p. 20

7.1  Description  p. 20

Security and privacy requirements are important to consider in the context of the present document. Regulatory requirements and user consent are mentioned throughout, emphasizing the importance of data confidentiality. The requirements listed below identify specific capabilities needed for authorization to support functionality described in other clauses of the present document. These requirements supplement the general security requirements for the 5G system defined in TS 22.261.
This clause includes requirements that provide functionality to define and enforce authorization policies. These policies are articulated in the case of avatar-based real-time communication to provide users with the ability to define specific authorization rights to use avatars and multimedia communication services on behalf of a subscriber.
