US 2026/0089480 A1 · METHOD FOR COMMUNICATION BETWEEN RADIO ACCESS NETWORK AND CORE NETWORK AND COMMUNICATION APPARATUS

Abstract

Embodiments of this application provide a method for communication between a radio access network and a core network and a communication apparatus. The method includes: A first wireless network device obtains first indication information of a first control plane network function serving a terminal device, where the first control plane network function is a network function determined based on a second control plane network function. The first wireless network device communicates with the first control plane network function based on the first indication information. This avoids a delay caused by proxy processing or forwarding of the second control plane network function when the first wireless network device communicates with the first control plane network function via the second control plane network function. Therefore, signaling can be reduced, and communication efficiency can be improved.
