METHOD FOR AN IMPROVED PROCESSING OF NETWORK COMMUNICATION BETWEEN A TELECOMMUNICATIONS NETWORK AND AT LEAST ONE USER EQUIPMENT BY MEANS OF REALIZING, WITHIN THE TELECOMMUNICATIONS NETWORK, NETWORK FUNCTIONS VIRTUALIZATION, TELECOMMUNICATIONS NETWORK, PROGRAM AND COMPUTER PROGRAM PRODUCT

摘要

The invention relates to a method for an improved processing of network communication between a telecommunications network and at least one user equipment by means of realizing, within the telecommunications network, network functions virtualization, wherein the telecommunications network provides a plurality of communication services to the user equipment, wherein the telecommunications network comprises at least one application server functionality, wherein the application server functionality is realized by means of a plurality of virtual network function instances, wherein the telecommunications network furthermore comprises a shared database functionality, wherein - in order for the telecommunications network to provide a specific communication service, out of the plurality of communication services, to the user equipment - subscription data, session data and/or call state data are required to be available to at least a first virtual network function instance out of the plurality of virtual network function instances, wherein the method comprises the steps of:-- in a first step, the subscription data, session data and/or call state data - required by the first virtual network function instance out of the plurality of virtual network function instances - are transmitted, by the shared database functionality, to the first virtual network function instance out of the plurality of virtual network function instances,-- in a second step, subsequent to the first step and in case of at least a change being applied to the subscription data, session data and/or call state data, the changed subscription data, session data and/or call state data or an updated version of the subscription data, session data and/or call state data is transmitted, by the first virtual network function instance out of the plurality of virtual network function instances, to the shared database functionality,-- in a third step, subsequent to the second step and in case of a failure of the first virtual network function instance out of the plurality of virtual network function instances, a second virtual network function instance out of the plurality of virtual network function instances resumes the functionality of the first virtual network function instance, using the changed subscription data, session data and/or call state data or the updated version of the subscription data, session data and/or call state data.
