In metaverse, digital humans (avatars) are widely used in business activities, such as advertising, news reporting, live shows. With the maturity of digital human technologies and the continuous growth of market demands, lifelike avatars have become reality in recent years. In the future, more and more people are expected to use their own avatar to participate in business activities in the virtual world. Especially, celebrities, famous professors and other people with special social positions have influences also in the virtual world. In some scenarios, authorization of avatar usage rights is needed for commercial or other purposes. If there were no proper management of avatar usage rights, it could cause the spread of false information, even result in chaos in virtual world. Therefore, the 5G system needs to support management and authorization of avatar usage rights. The owner of the avatar is expected to be responsible for the speech and behavior of his/her avatar. An individual or an enterprise has to be authorized by the owner of an avatar before using the avatar especially in business activities.

Singer J has her own lifelike avatar, which is used for her live concerts in metaverse. Her touching voice has won hundreds of millions of fans. Company A is a clothing manufacturer. Seeing the commercial value of Singer J, the company invited her to be the company's brand ambassador, who helps to increase brand awareness and attends product promotion activities. Singer J has signed one-year business contract with Company A. Subject to the contract, Singer J's avatar is the brand ambassador for Company A in metaverse. MNO B provides management services (including authorizing and deauthorizing) for the use of avatars in the mobile metaverse services. Each avatar has been assigned a unique identification code in MNO B's management system. MNO B also provides avatar storage services. Singer J is one of the subscribers of MNO B, and Company A is also served by MNO B.

1. Company A registers with the MNO B as an enterprise customer, while Singer J registers as an individual customer of MNO B. MNO B assigns IDs for Company A and Singer J respectively.
2. Singer J registers her personal avatar with MNO B. The avatar is lifelike and mapped to Singer J's ID in real world. So MNO B identifies and stores the avatar and its ID, also associates with the avatar's owner, Singer J's ID.
3. Company A sends a request for the usage rights of Singer J's avatar that is managed by MNO B.
4. MNO B sends a request to Singer J to ask for authorization of the avatar to be used in the mobile metaverse services.
5. After being confirmed by Singer J, Company A's usage rights of avatar has been authorized. MNO B updates the system with the information that Company A has the usage rights of Sing J's avatar.

Upon authorization, Singer J has granted the usage rights of her avatar to Company A for one year to be used in mobile metaverse services. During this year, Company A is authorized to use Singer J's avatar for business purposes. When Company A wants to use Singer J's avatar in a mobile metaverse service, the 5GS searches the avatar by its ID, and pushes the requested avatar to company A. At the end of the year, Company A's usage rights of Singer J's avatar will be duly terminated.
