Description

Technical Field

[0002] In existing methods, RAN (Radio Access Network) nodes and AMF (Access and Mobility Management Function) exchange non-UE (User Equipment) related data through the N2 interface via the NGAP (NG Application Protocol) process. Among these, one type of message in the N2 interface message exchange is that which is transparently transmitted from the core network NF (Network Function) to the RAN via the AMF in the form of an N2 Message Container (such as the broadcast message that MB-SMF (Multicast / Broadcast Session Management Function) wants to send to the RAN node).

[0003] However, the existing technology uses the NF←→AMF←→RAN method to forward data, which increases signaling routing latency and network overhead.

[0221] It should be noted that the relevant content on the wireless access network equipment side and the network function equipment side can be referred to each other, and the repeated parts will not be repeated.

[0222] The following is an example of the information transmission method provided in the embodiments of this application. The above application-level information is taken as non-UE related information, and the above network function device is taken as core network NF device or RAN device.

[0223] To address the aforementioned technical problems, this application provides an information transmission method, specifically a non-UE-related signaling interaction method based on RAN interface service-orientation. This method mainly involves: defining the interface architecture for interaction between the RAN (corresponding to the aforementioned radio access network equipment) and the core network NF (corresponding to an example of the aforementioned network function equipment) after RAN service-orientation; and defining the services and service operations of the RAN and core network NF based on this architecture. Figure 6As shown, the core network NFs such as AMF, MB-SMF, LMF (Location Management Function), CBCF (Cell Broadcast Center Function), and PWS (Public Warning System)-IWF (Interworking Function) can all call the services provided by the RAN node (corresponding to the aforementioned radio access network equipment) through the service interface Nran. The RAN node sends uplink messages to specific NFs (i.e., the corresponding NFs in the aforementioned core network NFs) by calling the services provided by the aforementioned core network NFs, so that specific NFs can call each other's services and exchange related messages with the RAN node, reducing signaling transmission latency. Specifically, Figure 6 The corresponding reference point architecture can be as follows Figure 7 As shown, each core network NF interacts with the RAN node's service interface Nran through its corresponding N2 interface.
