6.1 Introduction

There are services that spans domains, systems and functions to provide the service, this clause gives an overview of these services and which specifications that could be used to charge for the service.

6.2 5G LAN-type service charging

6.2.1 General

The 5G LAN-type service charging specified in the clause 5.34.10 of TS 23.501[215], including the 5G VN group management and 5G VN group communication.

The 5G VN group configuration is either provided by OA&M or provided by an AF to the NEF.

The 5G VN group management charging is applicable for the 5G VN group addition/deletion/modification (i.e.5G VN members), including the following two optional architecture specified in TS 32.254 [14]. which optional charging architecture to be used is depended on the operator’s decision.

– CEF based charging: obtains the 5G VN group information from UDM by CEF, and reports to CHF.

– NEF based charging: reports the 5G VN group charging information by NEF based on the API invocation from AF. NEF exposure function Northbound Application Program Interfaces (APIs) charging, using the NEF embedding the CTF.

The 5G VN group communication includes one to one communication and one to many communications. The 5G VN group communication charging is applicable for traffic forwarding via PDU session of 5G VN group members which covered by 5G data connectivity domain converged charging architecture specified in TS 32.255 [15], using the SMF embedding the CTF.

6.3 5G Edge computing services charging

Edge Computing support in 5GS is defined in TS 23.501[215], TS 23.502[214] and TS 23.548[217]. The architecture for enabling Edge Applications is specified in TS 23.558[218].

The charging principles for the Edge Computing domain are specified in TS 32.257[17] and TS 32.255[15].

The architecture of Edge Computing in Local Breakout roaming scenario and charging for Edge Computing in local breakout follows the principles in clause 5.5.3.9 are specified in TS.23.501 [215].
