Embodiment Construction

[0041] In the following, the system, method, node and computer program for provisioning services for roaming UEs according to the present invention are described in more detail.

[0042] Within the context of this application, the term "service" refers to a communication service or an application service. The communication service may be a packet transfer service such as Internet browsing, file delivery, file download, audio / video streaming, and the like. Communication services may also be voice calls, multimedia calls, chats, messaging, conferencing, and the like. An application service may be any service provided by an application or server, such as processing tasks on behalf of the UE (such as MTC), gaming, sensor data upload, sensor data analysis, remote control (also as a result of sensor data analysis) or monitoring task etc.

[0043] Within the context of this application, the term "user equipment" (UE) refers to, for example, a device that someone uses for his or her...

Abstract

The application relates to Network Function Virtualisation as standardised by ETSI GS NFV002 VI.2.1. The standard provides for dynamic instantiation and management of VNF instances. When using base stations as platforms on which VNFs can be instantiated, it has to be decided how this is done in an efficient way. The application proposes that in case a UE moves from an area covered by a source base station (210) to an area covered by a target base station (220), at least one VNF (250) is deployed on the target base station. This VNF may be a clone of a VNF (240) hosted by the source bases station.

Description

technical field [0001] The non-limiting and exemplary embodiments of the present disclosure relate generally to virtualized communication networks, and in particular to systems, methods, nodes and computer programs for provisioning services for roaming UEs. Background technique [0002] There is a continuing trend in the telecommunications field to "move network functions to the cloud", meaning that the implementation of corresponding network functions in general-purpose data centers involves large amounts of general-purpose (but cheap) processing hardware, instead of using dedicated and Specialized (but expensive) processing hardware. These data centers could even be owned and operated by different companies, and processing capacity would be leased out dynamically depending on demand and price. [0003] As the processing power of computing hardware increases, it becomes possible to use spare resources of network nodes to act as platforms for hosting more / other network func...
