Abstract

The invention relates to a method for routing data of an initialized session between a terminal and a server through a first network slice, the first network slice corresponding to a set of data processing functions of a communication infrastructure, the method being implemented by the terminal. The method comprises the steps of receiving from the server at least one routing identifier determined from at least one communication parameter of the session, configuring session information according to the received at least one identifier, and transmitting to the server subsequent data of the session routed through at least one second slice corresponding to the configured information.

Description

Method for routing data of an initialized session between a terminal and a server The present application is a divisional application of patent application of the application of which the application date is 2018, 11, 29, the application number is 201880077715.3, and the application name is "a method for routing data of an initialized session between a terminal and a server". Technical Field The application of the invention belongs to the field of telecommunication infrastructure and technology related to so-called "network slots" in english. Background Prior to the current 4G mobile networks being deployed in most countries, network architecture was most often based on highly specific devices dedicated to certain precise functions in both the access network and the core network, in particular functions related to packet transmissions to or from the mobile terminal. To date, in deployed network infrastructures, a single set of functions is used regardless of the type of traffic. Thus, the various session flows go through the same set of functions (routing, addressing, data flow control, naming, etc.). As this type of conventional architecture lacks its inherent flexibility and scalability, it has been considered to employ a more flexible architecture for the next generation mobile network (starting from the generation called 5G) to allow rapid response to highly varying demands in terms of traffic or quality of service. It should be noted that 5G networks are intended to cover both mobile and fixed networks. Thus, the technology involved in 5G network development applies to both fixed and mobile infrastructures. Among the solutions considered, one of the most promising solutions is based on a technique of dividing the network into slices (english "network slicing (network slices)"). This is because 5G will have to support widely varying usage scenarios and meet extreme requirements (e.g., in terms of speed, energy efficiency, device type, fragmentation of actors (actor), etc.), for which flexibility and scalability of the network are critical. Network slicing techniques are generally based on techniques related to virtualization and may be considered a technique for implementing specific communication path instances on the same physical infrastructure. This technology enables operators to create networks suited to different requirements (operators, service providers, clients) and to provide solutions meeting various requirements of different market segments. These solutions are optimized, for example, in terms of routing functionality, performance, isolation between applications or between clients. Currently, according to the known art, various methods are being considered to assign network "slices" (called "slices" in english) to terminals, and these methods are the subject of the proposal, in particular with respect to standardization (3GPP TR 23.799v2.0.0 of 12 in 2016 or evolution of wireless technology to 5G, 3GPP versions 13 to 15 and higher (5G america, 2 in 2017, pages 163 to 167). There are no solutions based on deployed technical solutions or assigning slices during deployment by the application provider (also called "THIRD PARTIES (third party)", in some documents). These third parties also play a role in the terminology used in the 5G network specification and in the department of communication services (english "Communication Service Providers (communication service provider)" (CSP)) that are considered "vertical" (in english, known as "SMART CITY (smart city)", in terms of health, etc.), also known as "Over the Top" (OTT). This is because these third parties have their own technical infrastructure enabling services to be provided to clients via the internet and fixed or mobile networks. These technical infrastructures consist in particular of servers, caches and routing and streaming service platforms using proprietary or standardized technical solutions. It should be noted that these technology infrastructures may also use technologies related to "network slicing" and in particular associate slices with traffic characteristics. However, there is no solution that provides visibility of slices at the terminal end or server end. Thus, for example, it is not possible to assign slices based on the communication characteristics of OTT applications in the transport layer and/or the application layer (e.g., in the context of the transport layer and/or the application layer being subject to significant evolution, especially due to third party behavior). The object of the present invention is to overcome some of the drawbacks of the currently used techniques. Disclosure of Invention The present invention aims at improving this situation by means of a method for routing data of a session between a terminal and a server initialized by a first network slice corresponding to a set of functions of a communication infrastructure for processing the data, implemented by the terminal and characterized in that i
