A Network Functions Virtualisation Management and Orchestration system, NFV-MANO, for managing resources in a Network Function Virtualisation Infrastructure, NFVI, has elements (NFVO, VNFM) for orchestrating and managing virtual resources to provide a network service and has an allocation element (VIM) for managing an allocation of physical resources for the virtual resources. One of the elements for orchestrating (NFVO, VNFM), obtains () information about which of the virtual resources could be affected by a planned adjustment of the allocation, and determines an impact () of the planned adjustment on a network service, based on this information. An indication based on the impact on the network service is sent () to the allocation element (VIM), which implements the planned allocation according to the indication. This can help enable a better trade off between allocation efficiency and quality of network service.

Managing planned adjustment of allocation of resources in a virtualised network

A system () includes a telecommunication network node (), a first unit () configured for sending information () relating to the status of the node (), and a second unit () configured for receiving information () for controlling the node (). A management unit () of the node () is connected with the second unit () and is configured for controlling the node () according to the information () received by the second unit (). The form of the information () sent by the first unit () and/or the information () received by the second unit () either does not include, or includes more than, only text. The invention also relates to use of such a system (), and methods and computer programs implementing the invention. In one embodiment, the first unit includes a camera configured for taking pictures of at least an outer surface of the telecommunication network node. This enables sending information of the telecommunication network node to be controlled, monitored and/or managed, so as to enable the detection, for instance, of any light-emitting diodes (LEDs) which would therefore provide evidence of an abnormal condition within telecommunication network node.

System for controlling a telecommunication network node, method and computer program therefor

Rerouting, as specified by ITU-T Q.730 is a network service that is executed by and under control of switching nodes, whereas IN services are executed under the control of a service control entity and invoked for certain calls only. Because of the two levels of control that are also separate from each other, inconsistencies may occur when an IN service is invoked for a call that may be in addition subject to rerouting. This problem is solved-in that a service control entity is adapted to perform the steps of receiving information relating to the rerouting of the call from the service switching entity, selecting a rerouting procedure for the call according to the received information, and sending an instruction to the service switching entity to continue the call according to the rerouting procedure. The information relating to the rerouting of the call information is in particular information about a rerouting capability of a preceding switching node.

Interaction between network services and intelligent network services for controlling rerouting of a call

A method for handling a call in an Intelligent telecommunications network, wherein the following steps are performed by a controller () providing logic for the Intelligent telecommunications network:&#x2014;receiving () a first information element relating to a precedence indicator of a call prioritization service,&#x2014;sending () a second information element derived from the first information element to a switch () for the handling of the call according to a priority indicated by the second information element. The method is particularly suitable for CAMEL networks in which the call prioritization service is eMLPP.
