Abstract
A communication method and apparatus, and a storage medium. A UE may send, to an AMF, an indication that the UE supports an enhanced LADN, or the AMF may obtain group subscription data from a UDM, so that the AMF can learn that the UE supports the enhanced LADN, and a group service area configured for the UE is at a DNN and S-NSSAI granularity. In this way, the AMF can perceive that an LADN processing capability of the UE is enhanced, and send a correct group service area to the UE.
