In some embodiments, the fifth communication device sending fifth information to the RAN network element, comprising:

in case the sixth condition is met, the fifth communication device sends fifth information to the RAN network element;

the sixth condition includes at least one of:

The RAN network element is determined to have information/event disclosure capabilities.

It is determined that the first CN network element has the second capability.

According to the embodiment of the invention, the fifth communication equipment sends the fifth information to the RAN network element, so that the information disclosure can be realized by assisting the RAN network element through the core network element, and a guarantee can be provided for quick adjustment of coding rate and the like of media services such as XR and the like.

The information disclosure method of the embodiment of the present invention is described below with reference to a specific application scenario.

Application scenario 1 of the embodiment of the invention. Referring to fig. 7, the method comprises the following steps:

step 0: the RAN network element has previously configured an address of a first CN network element (e.g., AMF) supporting RAN information/event disclosure.

Step 0 is optional.

Step 1, a RAN network element sends a first request message, namely an NG interface establishment request or other request information (first information), to a first CN network element (such as AMF);

first information comprising at least one of: description information of the RAN network element; the RAN network element supporting information/events provided for disclosure; requesting an auxiliary RAN network element for public information/events; first capability information indicating one of: the RAN network element has the capability of information/event disclosure, and the RAN network element does not have the capability of information/event disclosure; granularity of information/event disclosure supported by RAN network elements; the RAN network element supports a granularity range of information/event disclosure; a first request for requesting an auxiliary RAN network element to perform information/event disclosure; the RAN network element requests to assist the RAN network element to carry out information/event disclosure granularity; the RAN network element requests granularity to assist the RAN network element in information/event disclosure.

Optionally, the RAN network element may also send first indication information to the first CN network element, indicating that the NG interface establishment is only used for RAN information/event disclosure, not for serving the UE.

Step 2, the first CN network element (such as AMF) sends NG interface setup response to the RAN network element.

Alternatively, the first CN network element (e.g., AMF) may send first indication information to the RAN network element, indicating that the NG interface is established only for RAN information/event disclosure (e.g., RAN information disclosure at RAN granularity), and not for serving the UE.

According to the first indication information, when the RAN network element selects the AMF serving the UE for the UE, the first CN network element is not selected.

And 3, the first CN network element registers the service or updates the supported first service with the second CN network element (such as NRF) according to the first information, and provides the information/event disclosed by the support of the RAN network element, namely, sends the first registration information. Most of the first services are first services per RAN network element granularity, or first services per NG interface. The AMF also provides first public information associated with the first service to the NRF.

Step 4, the fourth CN network element generates or receives information/event query requirements disclosed by the RAN network element, for example, a QoS condition of a certain UE service, or a resource load condition of a certain area.

And 5, the fourth CN network element transmits first query information to the second CN network element (such as NRF) to query the first CN network element capable of providing RAN information.

Step 6, the first CN network element receives a first subscription request of a fourth CN network element, determines that the second request is used for requesting first information/event, and/or the second request includes at least one of the following: descriptive information of the first information/event;

and sending the second request to the RAN network element.

When the first CN already has corresponding RAN information. The information may also be returned directly without having to request the RAN.

And 7, the RAN network element performs measurement and returns corresponding information according to the second request.

Step 8, the RAN network element reports first information/event to the first CN network element;

and 9, the first CN network element reports the first information/event to the fourth CN network element.

Referring to fig. 8, an application scenario 2 of the embodiment of the present invention includes the following steps:

Step 0 is optional.

Step 1, the ran network element sends a first request message, i.e., an NG interface establishment request, to a first CN network element (e.g., DCCF).

The RAN network element sends first information to a first CN network element, wherein the first information comprises at least one of the following: description information of the RAN network element; the RAN network element supporting information/events provided for disclosure; requesting an auxiliary RAN network element for public information/events; first capability information indicating one of: the RAN network element has the capability of information/event disclosure, and the RAN network element does not have the capability of information/event disclosure; granularity of information/event disclosure supported by RAN network elements; the RAN network element supports a granularity range of information/event disclosure; a first request for requesting an auxiliary RAN network element to perform information/event disclosure; the RAN network element requests to assist the RAN network element to carry out information/event disclosure granularity; the RAN network element requests granularity to assist the RAN network element in information/event disclosure.

And step 2, the first CN network element (such as DCCF) sends an NG interface establishment response to the RAN network element.

Alternatively, the first CN network element (e.g., DCCF) may send first indication information to the RAN network element, indicating that the NG interface is established only for RAN information/event disclosure (e.g., RAN information disclosure at RAN granularity), and is not used for serving the UE.

And 3, the first CN network element registers service or updates supported first service to NRF according to the first information, and provides information/event for RAN network element support disclosure. Most of the first services are first services per RAN network element granularity, or first services per NG interface. The AMF also provides first public information associated with the first service to the NRF.

And 5, the second CN network element inquires the NRF of the first CN network element capable of providing RAN information.

Steps 6 to 9, such as steps 6 to 79 in application scenario 1, are not described herein.

Application scenario 3 of the embodiment of the invention: referring to fig. 10, the method comprises the following steps:

step 0: the fourth CN network element (e.g., AMF, SMF, PCF) sends fifth information to the RAN network element, the fifth information including at least one of: disclosing request information; a first measurement requirement; index information of the first CN network element or address information of the first CN network element; wherein the public request information is used for requesting one of the following: and requesting the RAN network element to perform information/event disclosure, and requesting the RAN network element to perform information/event disclosure through the CN network element.

The remaining steps 1 to 9 are as in steps 1 to 9 in fig. 8, and are not described here again.

In the embodiment of the invention, the information disclosure is realized by the core network element assisting the RAN network element, and the guarantee can be provided for quick adjustment of the coding rate and the like of media services such as XR and the like.
