- mapping the content flow (HPF-1; HPF-2; LPF-1; LPF-2) to at least one radio bearer in dependence on the at least one downlink radio condition and in

dependence on the at least one flow property;

- receiving the content flow (HPF-1; HPF-2; LPF-1;

LPF-2) ; and

The method according to claim 1, wherein the mapping comprises :

- selecting a unicast mapping of the content flow (HPF-1; HPF-2; LPF-1; LPF-2) to a plurality of unicast bearers between the network entity (gNB) and the subscribing user equipments (UE1, UEx) if the downlink radio condition permits the operation of the unicast mapping and if the flow property indicates the use of the unicast mapping, or

- selecting a multicast mapping of the content flow (HPF-1; HPF-2; LPF-1; LPF-2) to a multicast bearer between the network entity (gNB) and the subscribing user equipments (UE1, UEx) if the downlink radio

condition constrains the operation of the unicast mapping and if the flow property indicates the use of the unicast mapping.

The method according to claim 1 or 2, wherein the mapping comprises:

- selecting the multicast mapping of the content flow (HPF-1; HPF-2; LPF-1; LPF-2) to the multicast bearer between the network entity (gNB) and the subscribing user equipments (UE1, UEx) if the downlink radio condition permits the operation of the multicast mapping and if the flow property indicates the use of the multicast mapping, or

- selecting the unicast mapping of the content flow (HPF-1; HPF-2; LPF-1; LPF-2) to the plurality of unicast bearers between the network entity (gNB) and the subscribing user equipments (UE1, UEx) if the downlink radio condition constrains the operation of the multicast mapping and if the flow property

indicates the use of the multicast mapping.

The method according to one of the preceding claims, wherein

- selecting a multicast mapping of the content flow (HPF-1; HPF-2; LPF-1; LPF-2) to a multicast bearer between the network entity (gNB) and a first group of the subscribing user equipments (UE1, UEx) and a unicast mapping of the content flow (HPF-1; HPF-2; LPF-1; LPF-2) to a plurality of unicast bearers between the network entity (gNB) and a second group of the subscribing user equipments (UE1, UEx) if the downlink radio condition permits the simultaneous operation of the multicast and the unicast mapping and if the flow property indicates the simultaneous operation, or

- selecting the multicast mapping of the content flow (HPF-1; HPF-2; LPF-1; LPF-2) to the multicast bearer between the network entity (gNB) and the subscribing user equipments (UE1, UEx) if the downlink radio condition constrains the simultaneous operation of the multicast and the unicast mapping and if the flow property indicates the simultaneous operation.
