Data analytics for network automation utilizing user QoE data

1. A method performed by an Operations, Administration and Maintenance (OAM) management function, the method comprising:

receiving, from an application function, a request to change a network capacity of network resources for at least one service provided by an application function;

obtaining, from a function providing management data analytics services (MDAS), at least one of: a Quality of Experience (QoE) parameter, a Key Performance Indicator (KPI), and a Quality of Service (QoS) parameter derived based on at least one of:

data relating to at least one of service and performance, associated with at least one user provided by the application function, and

data relating to network performance associated with the at least one user; and

changing the network capacity of the network resources for the at least one service provided by the application function for the at least one user in dependence on at least one of: the QoE parameter, the KPI, and the QoS parameter.

2. The method according to claim 1 , wherein the OAM management function comprises at least one of: a Network Function Management Function (NFMF), a Network Slice Management Function (NSMF), and a Network Slice Subnet Management Function (NSSMF).

3. The method according to claim 1 , wherein the changing the network capacity of the network resources comprises reconfiguring resources allocated for the at least one user at the OAM management function and/or at another function.

4. The method according to claim 1 , wherein:

the at least one of the QoE parameter, the KPI, and the QoS parameter is derived based on the data relating to network performance associated with the at least one user, and

the method further comprises:

receiving, from the network function, a Nnwdaf Events Subscription Notify message including results of data analytics based on the data relating to at least one of service and performance, associated with the at least one user.

5. The method according to claim 1 , further comprising:

based on the request:

identifying a network slice related to the application function;

deriving new network requirements of the application function; and

initiating a modification of the network capacity of the network slice.

6. The method of claim 1 , wherein:

the receiving the request is performed in a case where an over the top service provider determines that the at least one of: the QoE parameter, the KPI, and the QoS parameter drops below a threshold, and

the changing the network capacity of the network resources includes improving QoE corresponding to the at least one of: the QoE parameter, the KPI, and the QoS parameter by a network provider corresponding to the OAM management function.

7. An Operations, Administration and Maintenance (OAM) management function comprising a controller and a transceiver, wherein the controller is configured to:

receive, from an application function, a request to change a network capacity of network resources for at least one service provided by an application function,

obtain, from a function providing management data analytics services, at least one of: a Quality of Experience (QoE) parameter, a Key Performance Indicator (KPI), and a Quality of Service (QoS) parameter derived based on at least one of:

data relating to at least one of service and performance, associated with at least one user provided by the application function, and

data relating to network performance associated with the at least one user; and

change the network capacity of the network resources for the at least one service provided by the application function for the at least one user in dependence on at least one of: the QoE parameter, the KPI, and the QoS parameter.
