This specification and claims of this application, and terms “first” and “second” are used to distinguish similar objects, but are unnecessarily used to describe a specific sequence or order. It should be understood that terms used like this is interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than those illustrated or described here. Furthermore, objects distinguished by “first”, “second”, and the like are usually of the same class and do not limit the number of objects. For example, the first object can be one or multiple. In addition, “and/or” used in this specification and the claims represents at least one of the connected objects. Symbol “/” usually represents an “or” relationship between front and back associated objects.

The terms “system” and “network” in the embodiments of this application are often used interchangeably, and the described technology can be applied to both the aforementioned systems and radio technologies, as well as other systems and radio technologies. The following describes a new radio (NR) system for the example purpose and uses the term NR in most of the following descriptions. However, these technologies can alternatively be applied to applications other than the NR system application, such as a 6th generation (6G) communication system.

To support determining a RAN network element that provides a piece of information/event, the following problems need to be solved:

There are requirements in media services such as extended reality (XR) as follows: Quality of service (QOS) information, a network state, and the like are provided to an application to enable the application to determine a code and a rate, to facilitate better scheduling of networks and avoid network congestion. Since a RAN does not support a servitization interface, a CN network element may be used to act as the RAN to provide public information through the servitization interface to facilitate service invocation.

How a first CN network element assists the RAN in publishing a piece of information/event provided by the RAN through the servitization interface, how to register services to a second CN network element (such as, but not limited to, an NRF, a BSF, a UDR, a UDM, and a charging function (CHF)), how to index the first CN network element in a case that a third CN network element (such as an AF and an NEF) needs to subscribe to the information/event of the RAN, and how the first CN network element indexes a RAN network element that provides the information/event are problems mainly resolved in this application.
