Abstract: A method performed by a network node to change a transport path for a user plane session in a radio communications network. The path prolongs along a first part between an antenna endpoint of a network node and a Packet Processing Function (PPF) instance serving the network node and a second part between the PPF instance and a Core Network (CN) endpoint. The network node identifies available CN endpoints in a CN, available PPF instances in a Radio Access Network (RAN) and of available antenna endpoints in the RAN that are available for the user plane session and comprises a number of possible transport paths for the user plane session. When detecting a change event related to the user plane session, the network node controls whether or not to change the transport path to any of the a number of possible transport paths for the user plane session.

Abstract: A new port state (called “Limited (Lim)”) and a new flag “Port-Limited”) are introduced. The Port-Limited flag is used to move a port of a network device from an Enabled state to the Limited state when the line protocol status for the port goes from down to up. In one embodiment, when the port is in the Limited port state, only a predefined set of protocols can work over the port.

Abstract: Network policies for providing a network service are managed in a Network Function Virtualization (NFV) environment. The policies are obtained from service requests and specify placement and lifecycle management of Virtual Network Functions (VNFs). Attribute values are extracted from each policy. The extracted attribute values include at least a policy type value which specifies an action performed by the policy. The policies are grouped based on the attribute values. The policies in the same group share at least a common policy type value. The attribute values are compared within each group to detect conflicts and redundancies before deployment of the network service and in real-time after the network service is deployed. One or more of the obtained policies are removed to produce a policy repository free of the conflicts and the redundancies.

Abstract: In one aspect of the teachings herein, a transmitter transmits synchronization signals according to one or more defined transmission characteristics that enable a receiver to distinguish the type of transmitter and/or the type of carrier used to convey the synchronization signals. Different types of transmitters reuse at least some of the same synchronization signal sequences and generation algorithms, but use different transmission parameters to impart one or more recognizable characteristics to the transmitted synchronization signals. In turn, an appropriately configured receiver “knows” which characteristics are associated with which transmitter and/or carrier types. For example, wireless devices operating in a wireless communication network transmit device-generated synchronization signals that reuse at least some of the same sequences used by network base stations for the transmission of network synchronization signals.
