Abstract: A method is disclosed performed by a system (115) of a home communication network (110) for enabling roaming to a visiting communication network (120) of a first wireless communication terminal (130) belonging to the home communication network. The method comprises receiving, from the visiting network (120), an information of a connection attempt from the first terminal at the visiting network, detecting whether federated cloud roaming is allowed for the first terminal, and when federated cloud roaming is allowed for the first terminal, sending a request to the visiting network to deploy virtual network functions (128) reflecting a number of network functions (117) existing in the home network.

Abstract: A method performed by an Operation and Support System (OSS) node for handling communication between a wireless device and a communication network node in a communication network, which communication network comprises a first radio access node associated with a first gateway and a second radio access node associated with a second gateway. The OSS node determines to initiate a change of an Internet Protocol (IP) address for the wireless device. The OSS node further identifies a session of packets for the wireless device, which session is run over a protocol that supports session continuity even though source or destination IP addresses change in the packets. Furthermore, the OSS node triggers the change of the IP address associated with the first gateway for the wireless device, of packets of the session, to a changed IP address associated with the second gateway.

Abstract: A method is discussed for balancing processing loads to at least a first and a second VM instances associated with the same processing circuitry. Information about first and second applications respectively running on the first and second VM instances is obtained. Incoming data corresponding to a first and second pluralities of jobs to be performed respectively by the first and second VM instances is received. Based on the obtained information and on the received data, a first number of the first plurality of jobs which the first VM instance is allowed to perform is determined by means of the processing circuitry, and a second number of the second plurality of jobs which the second VM instance is allowed to perform is determined by means of the processing circuitry. The first VM instance is instructed to release the processing circuitry after having performed the determined first number of jobs to allow the second VM instance to use the processing circuitry for performing the second number of jobs.

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: It is disclosed a client node, a first network node, a second network node, and methods therefore, for enabling forward error correction, FEC, of data. In uplink, the client node is adapted to transmit a lightweight FEC packet, enabling to save radio resources. The first network node is adapted to calculate a payload for the FEC packet and to append the payload to a “lightweight” FEC packet, and to transmit the thus modified FEC packet to an endpoint of the uplink. In the downlink, the second network node may be adapted to determine whether a received FEC packet is redundant or not, and is adapted not to transmit it as is, to an endpoint client node, if the FEC packet is redundant, enabling saving radio resources.

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 neighbouring second local service cloud. The NAT:ed IP address is unique at least in all local service clouds neighbouring 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.
