Abstract: Embodiments relate to e.g. a method performed by an orchestration node for managing network interfaces. The orchestration node sends to a function manager, trunk-port specific information of a trunk port to enable the function manager to unambiguously orchestrate trunk ports.

Abstract: Embodiments herein disclose for example a method performed by a controlling network node for handling one or more virtual network functions (VNF) in a communication network. The controlling network node initiates a setup of virtual resources for a VNF, wherein an aggregating connection point (CP), indicates a set of CPs to be connected to a same external virtual link. The controlling network node transmits configuration data to a managing function wherein the configuration data comprises an indication.

Abstract: Embodiments herein relate to e.g. a method performed by a node for handling a management operation. The node receives from an orchestration node, a request for an operation related to virtual network function operation. The node maps a first parameter associated with the request to a second parameter related to a cloud native template; and invokes an orchestration command comprising the mapped second parameter related to the cloud native template.

Abstract: Methods and network systems for enabling a network service for a client belonging to a home network (200) by using at least one Virtual Network Function, VNF (202D) of a Virtualized Infrastructure (202C) in a visited network (202). When requested by the home network, the visited network instantiates (2:10), a nested Virtualized Infrastructure Manager, VIM, (202E) which previously has been onboarded in the visited network and has been selected from a set of predefined VIMs supported by the home network. The visited network also instantiates (2:10) in the nested VIM a VNF package which has been onboarded in the visited network and having software needed to execute the network service. The network service can then be employed using the instantiated VIM and VNF package.

Abstract: A method for restoring connectivity between a node in an IP Multimedia Subsystem, IMS, network, and a User Equipment, UE. The UE is associated with a Proxy Call Session Control Function node, P-CSCF, of said IMS network, and with at least one control node of a packet access network, through which the UE connects to the IMS network. The method allows for restoring the connectivity of the UE to an IMS network node after said IMS node has failed to establish a communication to said UE via said P-CSCF node.

Abstract: An originating P-CSCF node receives a SIP INVITE request from first user equipment (UE) that originates a call to a second UE. If a relay candidate address for the first UE is not present in the SIP INVITE request, the SIP INVITE request is modified to include a first address provided by an originating IMS-AGW node as a relay candidate for the first UE and forwarded to the second UE. The originating P-CSDF node receives a SIP INVITE response message from the second UE in response to the SIP INVITE request. If a relay candidate address for the second UE is not present in the SIP INVITE response, the SIP invite response is modified to include a second address provided by an originating IMS-AGW node as a relay candidate for the second UE and forwarded t the first UE. The address information is used by both UEs in ICE operations.

Abstract: A network element included in a telecommunication system contains several nodes (1226, 1232, 1234, 1236, 1238) which are included in a system internal to this network element and provides internal network element functions in an internal bearer service network, and internal resources in the form of hardware and software which are used for performing the internal network element functions.The network element can offer an operations system a "white box" view, implying that internal resources are available to this operations system, enabling it to use managed objects representing the internal resources in order to manage the resources according to a second management information model in connection with using them for performing internal network element functions.

Abstract: A network element in a telecommunication network providing a number of different types of services, supports several telecommunication network applications (1304, 1306). It furthermore contains system resources and management information software. This software includes application specific management information and management information for system resources common to the applications, and is available to an operations system for managing the system resources when they are to be used. All of said management information is organized, from the point of view of naming, in several application specific management information bases each in the form of a respective hierarchical tree structure (1310, 1312).
