Communication method, user equipment, and single radio controller

A communication system, comprising:

• a single radio controller (SRC), configured to establish a first connection with user equipment by using a first communications network, and send non-access stratum (NAS) signaling or Layer 3 signaling of a second communications network to the user equipment by using the first connection, wherein the first communications network and the second communications network use different radio access technologies (RATs), and the SRC is configured to manage radio resources of the first communications network and the second communications network;
• the user equipment, configured to establish the first connection with the SRC by using the first communications network, and receive the NAS signaling or Layer 3 signaling of the second communications network from the SRC by using the first connection.
