    [0001] The invention relates to a system architecture for a digital information transmission network. It applies to the exchange of content conveyed by the Internet and concerns in particular geostationary satellite broadcasting satellites and non-geostationary communication satellite data transmission. The evolution of the richness of the contents conveyed by the Internet combined with a quality of experience of the users always growing, in particular in the instantaneity, that it is for the consultation of contents on line or for the games whose parts are put implemented between distant players, leads content providers and network operators to deport and duplicate content, when it makes sense, closer to users.
    [0002] The development of the Internet has led to an explosion of traffic in recent years due to the wealth of data transported, mainly because the streams concerned are video programs for the general public, for example NetFLix, Youtube, etc. . Transit networks (intercontinental fiber, national networks), collection networks (better known as "backhauling" in English) and access networks or "local access networks" are saturated. This results in packet loss by the routers and the need to retransmit the corresponding programs (television or video programs) as well as other streams that are also impacted accordingly and undifferentiated. The increase in transfer time induced by these retransmissions, due to a decrease in the performances of the networks, leads to a degradation of the quality perceived by the users. In an attempt to solve these problems, the network operators 30 have deployed more efficient infrastructures in terms of throughput and to carry large volumes, but it is an endless race between the increase in the capacity of the networks and that of the network. the wealth of content that has to pass through these same networks; as soon as the new infrastructures are deployed, new content encoding standards are available (SDTV, HDTV, 4K, 8K, ...).
    [0003] 5 An alternative approach has therefore been proposed by Internet operators operating telecommunication networks in order to offer a better quality of experience (QoE) to end-users (time to access content, rich content): Specific architectures for storage, management, access to content and management of user requests, known as Content Delivery Network or CDN allow through the duplication of content in "caches" placed closer to users to reduce the rate of contention in transit networks and therefore the time to access the same content. These CDNs were set up in the terrestrial networks and placed in the infrastructure networks of the telecommunication operators. Nevertheless, broadband terrestrial infrastructures can not reach all subscribers, especially for economic reasons, the cost of deploying fiber optics, ADSL copper networks, or 20 fourth-generation (4G) or fifth-generation (5G) wireless networks. ) can be unacceptable when the subscriber density becomes too low. Some actors have proposed in the past or more recently, the deployment of constellations of satellites in non-geostationary orbit NGSO (in low orbit: between 500 and 2000 km altitude, in 25 medium orbit, between 6 000 and 20 000 km altitude). This type of solution has a propagation delay compatible with those encountered in terrestrial networks, ie a few tens of milliseconds (ms) for the lowest orbits. On the other hand, the deployment of such a constellation requires the implementation of several tens (see the O3bNetworks, Globalstar or Iridium, Skybridge satellite networks) to several hundred satellites (see Teledesic or WorldVu) in order to guarantee a continuity of 3027173 3 services in inhabited areas of the globe. In addition, a low orbiting satellite provides limited capacity over a geostationary satellite in a comparable point-to-point configuration, but allows the cost of the space infrastructure to be limited by using several satellites per launcher. Because of their altitude and low latency, this type of satellite contributes to the efficient implementation of a telecommunication network, with performances comparable to those of terrestrial networks. Geostationary or GEO satellites (placed at a distance of 10 35 786 km in the plane of the Earth's equator) have the advantage of covering a large area of the Earth's surface (up to 1/3 of this surface); the same content can therefore be received simultaneously by several hundreds of thousands, or even millions of users, thereby reducing the cost of transmitting the same content in the same proportion. Nevertheless, the transmission delay of a geostationary satellite (more than 500 ms between two points of the Earth for a round trip) is much greater than the delays encountered in the terrestrial networks and incompatible for real-time users or with the quality of experience now encountered in terrestrial networks (a few tens of 20 milliseconds), in the case where the content must be downloaded through such a geostationary network in an interactive framework (as for example during a consultation on a page Web through a browser). Moreover, in order to circumvent this obstacle, specific protocols or devices (for example the "Performance Enhancement Proxy" protocol in English or 25 PEP) must be implemented by the satellite network operators in order to integrate their solutions in the networks. terrestrial networks, often to the detriment of security. In this document, the word "CDN" refers to a set of servers networked and cooperating to make content or data available to users through caches, a micro-cache corresponds to a cache located at the level of the network. of a geostationary or non-geostationary satellite network 3027173 4, a nano-cache designates a cache which is situated at the level of a user's access to the closest to a user (at the user terminal itself of the satellite network, serving a local loop connected to a set of users - a case of a village or a small business for example - or serving a single user - case of a home for example -). The term "cache" is well known to those skilled in the art and will not be explained. The term "end-user", "end-user", will be referred to as a user or user who accesses data content or transfers data to the network for data exchange with other users via a terminal intended to interact with a telecommunication network - whether terrestrial or not. The preliminary description indicates that the altitude criterion is essential for delivering a service enabling a non-terrestrial infrastructure network to integrate into terrestrial networks, the propagation delay being essential. Beyond non-geostationary satellites, other types of platforms fulfill this criterion: drones (unmanned aircraft) and stratospheric balloons (stabilized balloons). Subsequently, the term "low-orbit vehicle" will thus denote a non-geostationary satellite, a stratospheric balloon, a drone, for example. The NGSO terminology therefore extends in the rest of the patent to the expression "vehicle in low orbit". An NGSO network is a telecommunication network composed of land user stations, terrestrial access stations connected to telecommunication infrastructures, and a set of NGSO vehicles. Land-based stations are interconnected with access stations through NGSO vehicles. The invention is based in particular on the use of an architecture combining GEO geostationary satellites for broadcasting the most popular or anticipated content 30, and NGSO vehicles for access to real-time telecommunication services, or content not otherwise stored, following distribution by GEO satellites. The most consulted data will be deposited closer to users, in a nano-cache, which will lead to faster access to this data. The data stored in this nano-cache is accessed with a minimum response time by the users if the anticipation is correct. If the anticipation is not correct, a second level of cache, or micro-cache, storing indifferently all the contents coming from the geostationary satellites, is possible through the network NGSO, thus offering a level of performances in delay comparable to that of terrestrial networks. Real-time services, such as network games, are offered via a NGSO network. This architecture is therefore complementary to that of the terrestrial networks insofar as a CDN operator can use it according to the routing algorithms to obtain the best performances. The advantage of this solution is that it provides broadband services anywhere in the world by avoiding the need to deploy infrastructure collection or transit. Performance is also guaranteed to users everywhere in the world. The invention relates to a telecommunication system for the transmission of digital information between at least one content provider F1, and at least one set of users 14 comprising at least the following elements: a first geostationary satellite network R1 comprising at least one first geostationary satellite G1, at least one first access station SAG1 in association with one or more content providers Fi, at least one first subscriber station SG2 to the geostationary satellite, and at least one second station of subscriber SG1 to the geostationary satellite, - a second non-geostationary vehicle network R2 comprising at least a first SAN1 access station, at least a first non-geostationary vehicle network user station 3027173 6 SN1, at least one first vehicle in low orbit NG1 including means adapted to the exchange of low latency data between the first station access to the non-geostationary network and the first non-geostationary network network user station, 5 - a local loop B1 comprising one or more users Ui, - a first nano-cache N1 connected to the first subscriber station of the network geostationary R1 and adapted to store the content from content providers (Fi, i at least equal to 1) according to the profile of users, the first nano-cache N1 is also connected to the local loop B1 and the first subscriber station SN1 of the second non-geostationary network R2, - a first micro-cache M1 for storing content from the content provider F1 or content received through the subscriber station SG1 to the first geostationary satellite G1; the first micro-cache M1 is also connected to the second non-geostationary network R2 via SAN1 access stations, this connection of M1 to R2 being direct possibly through a terrestrial network T1, - at least one CDN cache (CDN1 ), comprising a routing algorithm adapted to determine a micro-cache to be used to find the content required by a user and which is not stored in a nanocache close to the user. The system may include means for managing the mobility of subscribed users at the local network level.
    [0004] The local loop B1 is, for example, a terrestrial access network of Wifi, 4G, 5G or FTTH type. A low-orbit vehicle network may be a network of non-geostationary satellites. The low-orbit vehicle network includes, for example, a stratospheric balloon or drone or a set of non-geostationary satellites, stratospheric balloons and drones, or a mixed set of these three types of platforms (balloons). stratospheres, drones or satellites). According to an exemplary embodiment, a user is connected to the networks by a local Wi-Fi loop comprising a central mast equipped with several non-geostationary and geostationary subscriber terminals of solar panels. According to an alternative embodiment, the GEO and NGSO networks operate in the same frequency bands according to principles of mutual protection, in particular by the so-called technique of geostationary arc avoidance by the NGSO network. The invention also relates to a method for the exchange of digital information between one or more content providers and one or more users, and between several users, said digital information being transported through several telecommunication networks, characterized in that it comprises at least the following steps: a first content provider F1 delivers its content in at least one first nano-cache N1 located to the users, and the nano-cache stores some or all of the content received according to 20 pre-established rules, through a first GEO R1 satellite network, - at the same time, the content provider delivers the content in at least a first micro-cache M1 maintained by a first geostationary satellite network R1, the first micro-cache stores all content issued by the content provider, - users 1.1; consult the content stored in the first nanocache N1, - if the content required by a user is present in the first nano-cache N1, then the first nano-cache delivers this content to the user Ui, 3027173 8 - if the content required is not present in the first nano-cache N1, then the content is searched in another micro-cache, a request is sent and transits through the loop B1, via the first nano-cache N1, via the first SN1 subscriber station to the network R2, 5 via NG1 non-geostationary vehicles and SAN1 access stations, if the services required are real-time services, then the transaction is performed directly via the network R2 from the B1 loop. The request to search the contents in a micro-cache is transmitted, possibly, through a terrestrial network T1. The method uses non-terrestrial networks integrated into the Internet for data exchange and content delivery. Other features and advantages of the present invention will appear better on reading the description of exemplary embodiments given by way of illustration and in no way limiting, appended figures which represent: - Figure 1, a representation of the world divided into several regions, - Figure 2, a representation of exchanges between several regional CDNs (or regional cache areas), 20 - Figure 3, an example of architecture according to the invention, and - Figure 4, an example of implementation from the system to a user level. In order to better understand the invention, the following description is given by way of illustration for the dissemination of content conveyed by the Internet network. Figure 1 shows an example of a global organization of a content delivery network. The network is considered a global CDN. Each region A: North America, B: South America, C: Europe and Middle East, D: Africa and Southern Europe, E: Eurasia, F: Middle 30 East and South East Asia, G: Oceania is defined so to be able to be covered by a geostationary satellite radio for the service of small receiving stations or user station of the GEO network at any point of this area by a single power amplifier and a single antenna, a single signal broadcast in every respect. Each of the zones is controlled by a regional CDN RA, RB, Rc, RD which is connected to the other CDNs of the other zones through an interchange CDN, CDX (FIG. 2). Figure 2 illustrates the control of regional CDN flows in their respective area. In each of the zones, all content providers (Fj) wishing to access the nano caches or users of the global CDN are coordinated by the regional CDN for regional users or 10 by the other regional CDNs. In order to have access to nano-caches intended for a list of users or end-users, the content providers follow the following procedure, for example: - an authorization is entered into by each content provider with each regional CDN in order to enable it to access the nano-caches 15 end users. Accreditation consists, for example, in the respect of a charter on the contents content, the neutrality of the network, the respect of the rights of the child, or the payment of a subscription, the maximum volume committed per month, copyright management, etc. when a content provider Fi wishes to issue a new content in the nano caches or users, it sends a request to the regional controller. The regional controller validates or not the access to the CDN network and allows the transmission to the nanocaches, or a list of nano-caches. These acknowledge the good reception of the contents according to principles known to those skilled in the art. In case the content has not been transmitted correctly, a new transmission is requested by the user. Content is stored in each nano-cache closest to a user. Each time the content is used, a token is transmitted to the content provider and to the regional controller of the CDN in order to manage the rights of use of the content.
    [0005] 3027173 10 The use of the content stored in the nano-caches can be managed according to the agreements put in place with the content providers: at the request of the users (potentially managed by a "aggregator" of intermediate content during consultations of the Web for example), or in broadcast mode (whether generalist, or according to a structuring of broadcast chain locally adapted to each group of users or even for each user according to their habits). In nano-caches, we will find: TV news, sports events selected according to the preferences detected according to the 10 users present in the local loop, locally adapted advertising sequences, for example, videos on demand, Daily, weekly, monthly, general or specialized newspapers depending on the demands or preferences of the local loop population.
    [0006] One of the objectives of the invention is to transmit content from a content provider via a geostationary satellite at the level of a nano-cache of a set of users; the retained content (Cd) in the nanocache is a function of the profiles of the end users and the rejected content (Cr) is that which does not correspond to these profiles, the management being carried out by the manager of the nano-cache, this manager being placed indifferently in the nano-cache or the infrastructure of the CDN. When a user wishes to consult a content (Cr) not retained in a nano-cache, this content (Cr) is transmitted via the NGSO network connected to a micro-cache located at an access station (also called connection station) of the NGSO network. A regional CDN routing algorithm can find the "best" micro-cache of the network, which will ensure the best performance of content distribution: the routing algorithm has not identified the content in the nano the next proximity cache will be the closest micro-cache connected through the NGSO network through an access station.
    [0007] FIG. 3 schematizes an example of an architecture that makes it possible to implement the method according to the invention. An F1 content provider accesses the geostationary satellite network R1 via a geostationary network access station SAG1.
    [0008] The content is broadcast over the broadcast region, in particular to a subscriber station SG1 geostationary network and subscriber station SG2 geostationary network. The subscriber station SG1 is connected to a micro-cache M1 which stores all the contents received from all the content providers. The stationary network subscriber station SG1, SG2 is connected to a nano-cache Ni which stores the contents according to the rules which have been defined to it. The nano-cache N1 is connected with a local loop B1, this local loop allows the interconnection of the nano-cache Ni with users U1, U2, etc. In the case where the content consulted or used by the users U1 or U2 can not be found in the nano-cache Ni, the users U1 or U2 are connected to a micro-cache M1 through a non-geostationary network NGSO R2, via on the one hand a subscriber station to the non-geostationary network SN1 - connected to Bi - and on the other hand a non-geostationary network access station SAN2 - connected to M1, through NGSO NG1 vehicles. All content access management is managed by the CDN operator CDN1. With regard to real-time services, such as network games for example, a user, U1 for example, will be connected to the Internet via the access loop B1, directly through the NGSO network, R2: the nano- cache N2 is then transparent.
    [0009] The network comprises a regional CDN comprising a routing algorithm adapted to determine a micro-cache to be used to find the content required by a user and which is not stored in a nano-cache close to the user. The non-geostationary vehicle network R2 comprises, for example, the network access station SAN1, a network user station with non-geostationary vehicles SN1, a vehicle in low orbit NG1, 3027173 12 comprising means adapted to the low-latency data exchange between the SAN1 access station and the SN1 user station. In particular, a subscriber station can be connected simultaneously or successively with the geostationary network and a non-geostationary vehicle. One of the functions of a regional CDN is to manage the access to the geostationary satellite by the stations content providers in order to optimize the distribution of the content in a nano-cache, by managing the rights of access and distribution, while minimizing distribution costs 10 for content creators. The access request issued by a content provider will be managed according to known techniques of access mode of a subscriber station to a satellite network in random mode. Simultaneously to all nano caches, a regional CDN receives all requests for content transmission, such as a subscriber to all 15 providers in its regional area. It also receives all the corresponding contents. A regional CDN is connected to terrestrial servers. It is then possible for a regional CDN to map the nearest nanocaches and / or micro-caches to access one or more contents located on other nano-caches in a very short time.
    [0010] The caches (micro or macro) are interconnected with the subscriber stations or the access stations directly or via terrestrial networks Th according to the proximity or the distance of caches with respect to these stations and quality of service constraints. A user can be mobile and change CDNs. When a user leaves a nano CDN, a micro-CDN, or a regional CDN, his content consumption profile can be shared, if he accepts, according to methods known to those skilled in the art. Content providers, for example, have VSAT stations of small diameter, typically less than 120cm, and low transmission power, for example, some Watt, to transmit bit rates of a few Mbps. These small stations of low power are associated with solar panels, for example, which makes them autonomous in energy and independent of any network. Each of these stations access a satellite placed on the region of interest by a transmission frequency chosen in the range Ka (27/30 GHz) or Ku 5 (12/14 GHz), a geostationary satellite receiving these emissions through a highly sensitive antenna having a significant merit factor and a large number of narrow brushes, unlike conventional radio broadcast satellites which rather use terrestrial transmitting stations of very large diameters (several meters) and very large power d emission (several hundred watts). The geostationary satellite G1, FIG. 3, receives the signal comprising the content to be broadcast and provided by the content provider. The signal is amplified by the geostationary satellite and transmitted to the nanocache stations of the different user groups of the system which select the content to be stored closer to a user. The signal is broadcast and transmitted once, either in Ka band (18/20 GHz) or in Ku band (11/13 GHz). Where appropriate, a digital signal processor, not shown for reasons of simplification of the figure, is positioned at the geostationary satellite and adapted to process the signals received from the content providers in order to repack them before changing frequency, and transmission to the earth. This treatment is known to those skilled in the art and will not be explained. Figure 4 is an example architecture of a local loop on which several users are subscribers. Several users Ui are connected to the satellite and non-satellite networks by a local loop 5G, 4G, FTTH or other comprising a central mast 40 equipped with several satellite terminals NGSO, 42 and GEO 43 of solar panels 44 allowing the contribution of energy to the operation of the system. Telecommunication modules, modulators, demodulators of the GEO and NGEO networks, storage means equip the central mast 40. An example of implementation of terminals may be the following: a subscriber station may have the dual function of GEO network subscriber station,; SG2 and network NGSO, SN1. The station may be provided with a simultaneous transmission capacity with the two networks or successively: the use of the GEO capacity will only be implemented when the NGSO capacity will not be used, the GEO function not being a priority. The invention is of interest in the fact that nano-caches can be deployed in a progressive manner depending on the users located in the loop and evolutions mass memory storage technologies, whose costs are increasing very quickly. Nano caches may initially have limited capacity and see their capacity increase gradually. On the contrary, micro-caches, placed in the infrastructure networks, can be managed as very large storage infrastructures such as data farms as they are known at present, physically co-located , or in the form of a "cloud" if necessary. The difference between the nanocaches and the micro-caches resides essentially in their storage capacity and the upgrade of their storage capacity. In this context, the proposed system architecture thus distributes the complexity of managing content storage resources and upgrading storage capacities. The invention can be implemented in a system based on a constellation of NGSO satellites avoiding the orbit of the GEO satellites for spectrum sharing. This allows the sharing of the same user terminal 25 when this terminal is automatically pointable, the GEO and NGSO modes can be exclusive of one another or simultaneous with two channels. The invention finds application in remote areas of urban centers, where it is difficult to deploy buried fiber-optic terrestrial networks or millimeter-based wireless networks for cost reasons: the density of the users is not important enough to hope for a sufficient return on investment. The solution using non-geostationary satellites, in low orbit, offers transmission delays of several tens of milliseconds, comparable to those of a fiber optic network and provides an advantageous complement to the optical fiber. The architecture according to the invention offers an extension to the terrestrial networks, ensuring access to the same services without modifying the protocols, with the same quality of service and experience for the users, while maintaining the compatibility of the requirements of the latency and security. The invention also alleviates the need for capacity of non-geostationary satellites, the content being in general often the same among all users. The infrastructure put in place therefore presents a perspective of sustainability compared to an NGSO system. The advantage of this solution is that it offers high capacity for growth: with local storage means, the band perceived by the users is almost infinite because they can download very rapidly a volume of more and more quickly (it it is sufficient to increase storage capacities by benefiting from the progress of the corresponding technologies, without changing the means of transmission in the networks). The modifications are therefore local, with incremental investments depending on the subscribers' local usage; without having to systematize the approach across the network.
