Abstract: Apparatuses and methods for controlling a manner of delivering content to a content user in a mobile telecommunication network are provided. The content is sent to the content user using first a first transmission rate when the content user is in a first radio state and uses a first battery power, and then using a second transmission rate that is lower than the first transmission rate, when the content user is in a second radio state and uses a second battery power that is smaller than the first battery power. The sending is performed such as, (A) while delivering the content, an amount of the content already received by the content user to exceed an amount of the content used by the content user, and (B) to minimize an energy used by the content user during delivery.

Abstract: A method in a network node for handling a traffic flow of a User Equipment, UE is provided. The network node is related to a local service cloud.

Abstract: Method in and a network node (160; 110; 401a, 600) for congestion management of a transport network (130) comprised in a wireless communications network (100). The wireless communications network (100) further comprises a base station (110; 401a) configured to receive data being transported via a data transport path (132; 404a,d) of the transport network (130) and to transmit the received data to one or more wireless devices (120) served by the base station (110; 401a).

Abstract: Methods and apparatuses maintain user-plane session status information of user equipment in an edge cloud. Upon determining that a handover of UE at a network edge has occurred, a status-information-acquisition mechanism is added to a handover signaling chain. The status-information-acquisition mechanism triggers providing UP session status information of the UE to a target gateway, which intermediates traffic between the target base station and a network device outside the edge cloud. The UP session status information of the UE is then used by the target gateway to determine UE-related data to be reported to the network device for execution of a function such as legal interception or charging.

Abstract: A method in a network node for handling a traffic flow of a User Equipment, UE. The network node creates a unique Network Address Translated, NAT:ed, Internet Protocol, IP, address mapping to an IP address of the UE. The NAT:ed IP address includes a local IP address prefix assigned to a related first local service cloud. The NAT:ed IP address is usable for the traffic flow both before and after a handover of the UE from the first local service cloud to a neighboring second local service cloud. The NAT:ed IP address is unique at least in all local service clouds neighboring to the first local service cloud, including the second local service cloud. The network node assigns the NAT:ed IP address to the UE for local break out of the traffic flow of the application session to the first local service cloud.
