1. A method for wireless communication, comprising:
establishing secure communication between a user equipment and a service application in a communication network by performing:
receiving, by the user equipment, an authentication and key management for service applications identifier (AKMAID) from an authentication server function (AUSF) network node upon successful completion of an authentication process for registering the user equipment with the communication network;
storing, by the user equipment, the AKMAID;
deriving, by the user equipment, an application key based on a base authentication key;
sending, by the user equipment, a communication request to the service application, the communication request comprising the AKMAID; and
receiving, by the user equipment, an application session establishment response to the communication request from the service application to establish a secure communication session between the user equipment and the service application based on the application key,
wherein:
the service application, upon receiving the communication request from the user equipment, determines whether the service application has a pre-shared application key for the user equipment, and
in response to the determination that the service application does not have the pre-shared application key for the user equipment, the service application sends a first request for the application key to an AKMA Anchor function (AAnF) network node, the first request comprising the AKMAID.
