Abstract: The present invention relates to Edge Computing (EC) systems. The invention presents an EC entity of an EC system, and a Mobile Communication Core (MCC) entity for a MCC system, like a 3GPP system. The EC entity is configured to obtain topology information of the EC system, and expose the topology information to another network, in particular to a MCC system. The MCC entity is configured to receive topology information of an EC system from the EC entity, and provide the topology information to a Network Exposure Function (NEF) or to a Policy Control Function (PCF) of the MCC system.

Abstract: An edge computing (EC) entity belongs to an EC system, and a mobile communication core MCC entity belongs to a MCC system, like a 3GPP system. The EC entity is configured to obtain topology information of the EC system, and expose the topology information to another network, in particular to a MCC system. The MCC entity is configured to receive topology information of an EC system from the EC entity, and provide the topology information to a network exposure function (NEF) or to a policy control function (PCF) of the MCC system.

Abstract: A control plane network entity for providing a multicast/broadcast service for one or more user equipments in a cellular communication network is provided. The control plane network entity is configured to: receive a session setup request for a multicast/broadcast session for the user equipments, wherein the session setup request comprises one or more identifiers identifying the user equipments and/or one or more spatial regions the user equipments are located in; select one or more access and mobility management function entities of the cellular communication network based on the one or more identifiers for providing the multicast/broadcast session to the user equipments; and send a user plane session setup request to the selected one or more access and mobility management function entities. Moreover, the disclosure relates to a user plane network entity and a radio access network node for anchoring and providing a multicast/broadcast service respectively.
