1. A communication method, comprising:
receiving, by a first radio access device, a first message from a second radio access device, wherein the first message comprises:
a first control plane message for an interface between a first radio backhaul device and the second radio access device, and
first indication information which indicates a first type of the first control plane message;
receiving, by the first radio access device, a configuration message from the second radio access device, wherein the configuration message comprises a mapping relationship between
different types of control plane messages for the interface between the first radio backhaul device and the second radio access device, wherein the different types of control plane messages include the first type of the first control plane message, and
corresponding different radio bearers for communication from the first radio access device to the first radio backhaul device;
determining, by the first radio access device and among the different radio bearers, a first radio bearer corresponding to the first type of the first control plane message based on
the first type of the first control plane message included in the first indication information, and
the mapping relationship included in the configuration message; and
sending, by the first radio access device, a second message to the first radio backhaul device by using the first radio bearer, wherein the second message comprises the first control plane message,
wherein both the first radio access device and the second radio access device are connected to the first radio backhaul device.
