Methods and apparatuses for service layer charging correlation with underlying networks

A server in a service layer comprising a processor and a non-transitory memory including computer-executable instructions which, when executed by the processor, cause the server to:

• send, via the server located outside of an underlying 3GPP network, a trigger request to an underlying 3GPP network, where the trigger defines a QoS parameter change event in the underlying 3GPP network, and where the underlying 3GPP network is configured with functionality to send a notification to the service layer upon detecting the QoS parameter change event;
• receive, from the underlying 3GPP network, the notification the detected QoS parameter change event has occurred;
• and
• perform, at the service layer residing on the server, a service layer operation in response to the received notification.

A computer-implemented method comprising:

• receiving, at an underlying 3GPP network, a trigger request from a service layer, the service layer residing on a server located outside of the underlying 3GPP network, the trigger defining a QoS parameter change event in the underlying 3GPP network, and the underlying 3GPP network being configured with functionality to send a notification to the service layer upon detecting the QoS parameter change event;
• producing, at the underlying 3GPP network, the notification based on the detected QoS parameter change event occurring;
• and
• sending, from the underlying 3GPP network, the notification to the service layer as a result of the detected QoS parameter change event.

An underlying 3GPP network with supported functions that communicates with a service layer for updating charging operations comprising a processor and a non-transitory memory including computer-executable instructions which, when executed by the processor cause the underlying 3GPP network to:

• receive, at the underlying 3GPP network, a trigger request from the service layer, the service layer residing on a server located outside of the underlying 3GPP network, the trigger request defining a QoS parameter change event in the underlying 3GPP network, and the underlying 3GPP network being configured with functionality to send a notification to the service layer upon detecting the QoS parameter change event;
• produce, at the underlying 3GPP network, the notification based on the detected QoS parameter change event occurring;
• and
• send, from the underlying 3GPP network, the notification to the service layer as a result of the detected QoS parameter change event.
