8.12 Dynamic EAS instantiation triggering

8.12.1 General

The EES may trigger the EAS instantiation dynamically due to e.g., EAS discovery request, UE mobility, upon receiving EEC Registration request containing AC profile.

Upon receiving the EAS discovery request with EAS discovery filter from the EEC or the S-EES during the procedures for EAS discovery or ACR, the EES may fail to discover and select the EAS that matches the UE location and the requesting application characteristics specified in table 8.5.3.2-2 due to no EAS is available or instantiated. The EES may trigger the EAS management system to instantiate the EAS serving the AC in the EDN before returning the EAS information to the EEC or S-EES, based on the pre-configured dynamic EAS instantiation information about which EAS can be dynamically instantiated at the associated EDN.

NOTE 1: The EAS management system is responsible for the authorization of the dynamic EAS instantiation.

NOTE 2: The EAS management system can provide the pre-configured dynamic EAS instantiation information to the EES. Such a mechanism is out of scope of this release of the present document.

NOTE 3: Dynamic EAS instantiation information at the EES is left implementation specific in this version of the specification.
