Embodiments of this application are introduced below in conjunction with the accompanying drawings of the specification. In the following introduction process, an example in which the embodiments of this application are applied to the network functional structure as shown in
As shown in
S11: a NWDAF determines a UE to be monitored for which network data analytics is required, and a type of data analytics for the UE to be monitored.
In the embodiment of this application, the NWDAF determines the UE to be monitored for which the network data analytics is required, and a type of data analytics corresponding to a requirement of data analytics, according to a UE identity and the requirement of data analytics configured by a static configuration, or according to a UE identity and the requirement of data analytics carried by a request of data analytics from a network function. Unless otherwise specified, “UE” mentioned in the subsequent content herein may refer to the UE to be monitored.
In a practical application, types of data analytics corresponding to different demands of data analytics are generally different. In the embodiment of this application, the types of data analytics may include moving trajectory analytics, service traffic analytics and the like.
S12: the NWDAF determines a provider network function and a monitoring event for the UE to be monitored according to the type of data analytics, wherein the provider network function provides source data, corresponding to the type of data analytics, of the UE to be monitored, and the monitoring event indicates the provider network function to monitor the source data.
In the embodiment of this application, after the NWDAF determines the UE for which the data analytics is required and the type of data analytics, on one hand, the NWDAF can determine the monitoring event corresponding to the type of data analytics, i.e., the UE-related data to be monitored or collected, the monitoring event can be an event subscribed by the NWDAF to a network function providing the data, which indicates the data corresponding to the type of data analytics to be collected, for example, could be location information or data traffic information.
On the other hand, the NWDAF may also determine the provider network function for providing the source data corresponding to the type of data analytics for the UE according to the type of data analytics, and the UE is the UE required to acquire the source data indicated by the UE identity. The provider network function in the embodiment of this application may be any one or more of the AMF, the SMF, a next generation-radio access network (NG-RAN) and the UPF. For example, if the source data is the location information of the UE, the provider network function may be the AMF taking charge of the mobility management, or if the source data is the traffic information of the UE, the provider network function may be the SMF for the session management and the UPF connected with the SMF.
In a practical application, after the NWDAF signs a contract with the provider network function for a corresponding monitoring event, the provider network function may be indicated to monitor, acquire and even report the source data, related to a data type, of specific UE in slices.
S13: the NWDAF transmits the monitoring event to the provider network function.
In the embodiment of this application, when the NWDAF transmits the monitoring event to the provider network function, the following manners may be adopted, but are not limited.
Manner 1: the NWDAF may transmit the monitoring event to the UDM or the PCF, and furthermore, the UDM or the PCF transmits the monitoring event to the provider network function.
For example, the NWDAF may transmit a monitoring event that the location information of the UE is monitored to the UDM or the PCF, and the UDM or the PCF further transmits the monitoring event to the AMF which serves for the UE, to monitor the location information of the UE.
Manner 2: the NWDAF may also transmit the monitoring event to the NEF, then, the NEF transmits the monitoring event to the UDM or the PCF, and furthermore, the UDM or the PCF transmits the monitoring event to the provider network function.
For example, the NWDAF may also transmit a monitoring event that the location information of the UE is monitored to the NEF; the NEF further transmits, the event that the location information of the UE is monitored, through the UDM or the PCF; and the UDM or the PCF further transmits the monitoring event to the AMF which serves for the UE, to monitor the location information of the UE.
In a practical application, the NWDAF may also transmit an address (a NWDAF address) or an equipment identity of the NWDAF while transmitting the monitoring event (in manner 1 or 2, for example), so that the provider network function may directly report the acquired source data to the NWDAF later according to the NWDAF address or the equipment identity. Of course, the NWDAF may also transmit the UE identity of the UE to be monitored, or the UE identity may also be carried in the monitoring event.
S14: the provider network function receives the monitoring event and monitors the source data, corresponding to the type of data analytics, of the UE to be monitored according to the monitoring event.
In the embodiment of this application, the NWDAF may transmit the monitoring event to the UDM or the PCF directly or through the NEF, and then, the UDM or the PCF transmits the monitoring event to the provider network function, so that the provider network function may receive the monitoring event from the NWDAF by communication of the communicating UDM or PCF.
For example, the provider network function receives the monitoring event from the NWDAF through the UDM or the PCF, or the provider network function receives the monitoring event from the NEF through the UDM or the PCF, wherein the monitoring event in the NEF is an event transmitted by the NWDAF.
Furthermore, the provider network function may monitor the source data, corresponding to the type of data analytics, of the UE according to the monitoring event. For example, the AMF monitors the position of the UE in real time, or the SMF monitors service traffic such as the traffic rate of the UE.
S15: the provider network function reports the source data, corresponding to the type of data analytics, of the UE to be monitored to the NWDAF.
After monitoring the source data, corresponding to the type of data analytics, of the UE according to the monitoring event, the provider network function may report the monitored source data of the UE according to an analytics demand. For example, the provider network function may report the source data of the UE to the NWDAF when a monitoring condition is met, for example, the provider network function monitors the change of the position or the traffic rate of the UE.
In a practical application, the provider network function may report the monitored source data of the UE in real time or at intervals. For example, if the UE is in a moving state, the position of the UE is continuously changed, then, the AMF serving for the UE may report the position, such as the changed position, of the UE in real time. Or if the UE is in a semi-moving state, for example, the UE is in the moving state and a static state in turns, the position of the UE may be discontinuously changed, and thus, the changed position of the UE may be reported. Of course, it is also necessary to set an interval time according to a monitoring demand, and the provider network function may report the source data of the UE once every other the interval time.
In the embodiment of this application, when reporting the monitored source data, corresponding to the type of data analytics, of the UE, the provider network function may reversely transmit the source data of the UE according to a transmission path of the received monitoring event and report the source data to the NWDAF.
For example, the source data of the UE may be transmitted to the UDM or the PCF by the provider network function and then reported to the NWDAF by the UDM or the PCF. Or the provider network function transmits the source data of the UE to the UDM or the PCF, then the UDM or the PCF transmits the source data to the NEF, and then the NEF reports the source data to the NWDAF.
In another embodiment of this application, if the NWDAF further transmits the NWDAF address/equipment identity to the provider network function while transmitting the monitoring event in step S13, the provider network function may directly transmit the source data, corresponding to the type of data analytics, of the UE to the NWDAF according to the NWDAF address and/or equipment identity in step S15.
For example, if the provider network function is the AMF, the AMF may directly transmit the position of the UE monitored in real time to the NWDAF according to the NWDAF address and/or equipment identity, so that the transmission path is shortened, and the rate of reporting the network data is increased.
Or, in another embodiment of this application, if the NWDAF transmits the monitoring event in manner 2 and the NEF also carries an NEF address/equipment identity of the NEF while transmitting the monitoring event to the provider network function in step S13, the source data, corresponding to the type of data analytics, of the UE may be directly transmitted to the NEF by the provider network function according to the NEF address and/or equipment identity of the NEF and then the source data is reported to the NWDAF by the NEF in step S15.
S16: the NWDAF receives the source data, corresponding to the type of data analytics and reported by the provider network function, of the UE to be monitored, and analyzes and processes the received source data to generate a result of data analytics, conforming to the type of data analytics, for the UE.
The source data of the UE, received by the NWDAF, may be the source data, directly reported by the provider network function and corresponding to the type of data analytics, of the UE to be monitored, such as the traffic information directly reported by the SMF according to the NWDAF address.
Or, the source data of the UE, received by the NWDAF, may be source data which is not directly reported by the provider network function. Such a manner includes two situations as follows.
Situation 1: the NWDAF receives the source data, corresponding to the type of data analytics and reported by the provider network function through the UDM or the PCF, of the UE. For example, the NWDAF receives the location information of the UE, reported by the AMF through the UDM or the PCF.
