Methods for ue/ac/eec authorization in group services provided by common eas using a group server

A method implemented by a wireless transmit/receive unit (WTRU), the method comprising:

• sending a discovery request to an edge enabler server (EES), wherein the discovery request comprises an indication of an application client (AC) at the WTRU, an indication of a group profile associated with the AC, and AC authorization credentials, the AC authorization credentials comprising an authorization scope and a token digitally signed by an application server (AS);
• receiving a discovery response message, wherein the discovery response message comprises information associated with an edge application server (EAS) for the AC, wherein the discovery response message further comprises an indication that the AC is authorized for a group session with the EAS;
• and
• providing the information associated with the EAS to the AC for communication with the EAS.

A group server (GS) comprising:

• a processor configured to:
• receive a first group allocation request message, wherein the first group allocation request message comprises information associated with a first application client group profile (AGP), wherein the first group allocation request message further comprises information associated with a first Edge Application Servers (EAS), wherein the first AGP comprises a first applicant client (AC) authorization token and a first AC authorization scope;
• generate allocation information that associates the first AGP with the first EAS based on a determination that the first AC authorization token and the first AC authorization scope are successfully validated by the GS;
• and
• send a first group allocation response message to a first Edge Enabler Server (EES), wherein the first group allocation response message comprises the allocation information.
