[0002] At present, the core network defines the Network Exposure Function (NEF) to realize network capability exposure, which can support applications to safely provide some user behavior and service-related information to the 3GPP network, and also support the external exposure of core network data analysis capabilities. The current capability exposure solution only supports the exposure of related network capabilities on the core network side, and does not consider the exposure of related air interface information on the wireless access network side.

[0003] Traditional wireless access networks are mainly used to provide wireless access service capabilities to ensure reliable transmission of users and services. At present, the opening of wireless network capabilities has also received more extensive attention.
