Definitions
- the present invention relates to an optimized device for broadcasting information over a telecommunication network.
- the invention relates more particularly to the field of multimedia telecommunications services.
- the mobile Internet offers a privileged application perspective for the broadcasting device according to the invention.
- the invention is intended for advertisers who wish to increase the effectiveness of their information campaign by targeting more the groups of persons concerned via a telecommunications network.
- Pull techniques are not suitable for distribution. These techniques can only be implemented on condition that the user has been previously informed of the existence of the information made available on the network. Thus, the population affected by dissemination is small, even if in proportion to this affected population, the percentage of population interested in transmission is significant.
- the dissemination of information can also be carried out by another technique called “Push”.
- Push This technique consists for a content provider in widely disseminating the information it wishes to transmit. Customers then have access to the information disseminated through appropriate receivers free of charge or for a fee. Radio and television are quite significant examples of the application of these so-called push information dissemination techniques. If the techniques of push make it possible to minimize the occupation of bandwidth compared to the techniques of Pull the same information being generally conveyed only once in a given node of the network, the quality of the information made available of users is very poor compared to that obtained with pull techniques. Indeed, the information sent corresponds to targeting a priori the areas of interest of the users and an individual who receives information through such a communication channel finds himself facing a significant amount of information which does not are not necessarily of interest to him.
- the problem which the invention proposes to solve is to provide an information dissemination device allowing advertisers to route the information for which they are responsible to the segment of the population which will be the most receptive, while alleviating the drawbacks of diffusion techniques according to the prior art.
- the device according to the invention is intended to be more effective on the one hand, in terms of bandwidth and, on the other hand, in terms of the ratio of the population concerned to the population affected.
- the invention provides on the one hand, to take into account the profile of users so as to direct the dissemination of information to users whose profile more closely matches that of target population and, on the other hand, take into account the network load to minimize the cost of information transmission.
- the elements of information to be disseminated are associated with dissemination criteria on the one hand, and with routing constraints on the other hand, with a view to simple filtering on reception.
- Filtering is therefore carried out on the basis of objective criteria such as geographic position, climatic environment, linguistic environment, etc. Filtering can possibly be carried out on the basis of subjective criteria such as professional situation, leisure activities, user interests, etc.
- the setting up of cache memory in certain nodes of the network makes it possible to optimally exploit the peaks in the load of the network.
- the invention therefore relates to a device for distributing information in an access network consisting of several interconnected nodes making it possible to convey streams of information elements between content providers and reception terminals, characterized in that said device is installed at at least one node of the network, and in that it comprises a circuit for managing the profile of the node configured by a network or node operator according to objective or even subjective criteria and a filtering mechanism broadcast pieces of information that control a switch to filter said pieces of information.
- the device further comprises a mechanism for synthesizing the profiles of the downstream nodes making it possible to automatically update the circuit for managing the profile of the node in which said broadcasting device is located as a function of subjective criteria.
- the device further comprises a cache memory for temporarily storing the filtered information elements, and a mechanism for retransmission of the information elements thus stored.
- the device according to the invention is characterized in that it applies to any type of access network.
- the device according to the invention is characterized in that it applies to a mobile radio network access network.
- the device can also be applied to an access network of mobile radiocommunication networks in which a spatial segment is implemented.
- FIG. 1 is a diagram illustrating the installation of the device in a node of the access network.
- FIG. 1 therefore illustrates the installation of the device according to the invention in a node of an access network. It can be an input node, an output node or an intermediate node of the access network.
- An access network comprises a plurality of branches each consisting of several interconnected nodes.
- the device can then be installed in several branches of the access network as well as in several interconnected nodes of a branch of the access network. It is therefore considered that the device according to the invention is installed at the level of at least one node of the access network.
- the node 1 of the network in which the optimized broadcasting device is installed information is connected on the one hand, to another node of the network located upstream 2 and, on the other hand, to one or more other nodes of the network located downstream 3.
- the operator 4 has the possibility of connecting a management equipment on node 1 so that it can be configured or analyzed.
- Node 1 receives input streams of information from upstream node 2.
- a mechanism for synthesizing the profiles of the downstream nodes 10 located within the node 1 is provided to receive as input information concerning the profile of the downstream nodes. It is however possible not to activate and not to implant the synthesis mechanism 10 within node 1.
- the information concerning the profiles of the downstream nodes is provided for going back from the downstream node 3 to the node 1.
- the mechanism 10 which operates the synthesis of the profiles of the downstream nodes provides its results to a management circuit of the profile of the node 8, which circuit is also configured by the network operator 4.
- the node 1 where the device is located also includes a filtering mechanism 6 which receives, on the one hand, the profile of the node established by the circuit for managing the profile of node 8 and, on the other hand, broadcasting criteria and routing constraints associated with the elements of the information flows.
- the . filtering mechanism 6 controls a switch 5 to store elements of information in a cache memory 7.
- a retransmission mechanism 9 is finally provided in node 1 to retransmit the elements of information stored destined for the downstream node 3.
- the retransmission mechanism 9 acts as a function of the commands associated with the flow of information entering the node 1.
- the node 1 in which the device according to the invention is installed is therefore endowed with a certain number of additional functions compared to a classic node of an access network.
- the diffusion device makes it possible first of all to implement the characterization of the profile of the node.
- the characterization of the profile of the node is implemented in particular by means of the profile management circuit of the node 8.
- This circuit 8 can be configured by the operator of the network 4 or possibly by the operator of the node.
- the profiles of the downstream nodes 3 go back to the network and are processed in the mechanism for synthesizing the profiles of the downstream nodes.
- the result of this processing is then supplied to the node profile management circuit 8.
- a variable component typically subjective criteria
- an update of the node profile can be envisaged. automatically.
- the characterization of the node profile can thus be updated in real time thanks to the device for synthesizing the downstream nodes 10.
- the broadcasting device therefore makes it possible to operate a filtering of the streams of information broadcast according to objective, even possibly subjective, criteria.
- the filtering of the information elements received in the node 1 is based on the comparison between the dissemination criteria associated with the information elements and the criteria of the profile of the node. In the event of a match, the information element is kept in the cache memory. Otherwise, the information item is discarded.
- Information is therefore disseminated in a segmented form in the form of information elements.
- a piece of information only deals with one or a few subjects.
- a header is associated with the information element and specifies its dissemination criteria and the time constraints for the delivery of information to users.
- Each element of information in an information flow is therefore associated with information characterizing it.
- information specifying the time constraints for routing information to users and information allowing filtering according to objective or even subjective criteria.
- the geographic area of diffusion can be specified for example by a disc characterized by a center and a diameter.
- the filtering mechanism 6 therefore receives as input on the one hand, the profile criteria from the profile management circuit of node 8 and, on the other hand, the information associated with a given piece of information making it possible to characterize it.
- node 1 is provided with a cache memory 7 which makes it possible to store part of the information broadcast. For example, any exit node of the access network located in the geographical area indicated must keep the broadcast information in its cache memory.
- the device according to the invention further comprises a retransmission mechanism 9 of the information elements stored in the cache memory 7.
- the presence of the cache memory 7 in the node 1 of the network where the device is installed makes it possible to disseminate information during network load peaks.
- Each item of information disseminated is associated with information characterizing it, in particular information allowing filtering according to objective or even subjective criteria as explained above.
- Each element of the information flow broadcast is also associated with retransmission commands specifying the time constraints. routing information to user terminals such as for example a retransmission and / or routing time slot, or even the repetition frequency of the broadcast, etc.
- the retransmission mechanism 9 therefore determines the type of retransmission as a function of the retransmission commands associated with the information elements received.
- the node of the network 1 where the device is located is provided with special means allowing the optimized diffusion of information in the network intended for the downstream nodes which are in its coverage area.
- the optimized information dissemination device can be installed at at least one node of the access network without the cache memory 7 and without the retransmission mechanism.
- the device according to the invention then only comprises the circuit for managing the profile of the node 8 configured by the network operator or of the node 4 as a function of objective or even subjective criteria, and the filtering mechanism 6 of the information items broadcast which controls the switch (5) so as to filter the information elements.
- the device filters the pieces of information received according to the criteria of the profile of the node where it is located and it then directly transmits the pieces of information whose distribution criteria correspond to the criteria of the profile from the node to the nodes downstream located in the coverage area without taking into account the network load peaks or the constraints of delay in routing information to users.
- the filtering mechanism (6) commands the switch (5) to discard the item of information.
- the device thus implanted may nevertheless also include the mechanism for synthesizing the profiles of the downstream nodes 10, so as to automatically update, according to subjective criteria, the circuit for managing the profile of the node 8 in which the device is installed. .
- the access network consists of two types of node: nodes of the base station controller type and base station type nodes.
- the device according to the invention can be installed, for example, at a base station, that is to say at a network output node.
- the downstream node as shown in FIG. 1 is then directly a user terminal and the upstream node a base station controller.
- the groups of users covered by one or more base stations in which the device according to the invention is implemented therefore benefit from programs adapted to their needs. Indeed, the information elements made available to them are perfectly targeted since they are based on the environment covered by the node considered, even on the synthesis of the characteristics linked to the profiles of the users connected to the node.
- the device according to the invention can also be installed at the level of a base station controller, that is to say at the level of an input node of the access network.
- the downstream nodes then correspond to base stations and the upstream nodes correspond to nodes of the core network of the mobile radiocommunication network.
- the optimized information dissemination device according to the present invention can also be applied to a satellite access network.
- a satellite access network mainly consists of three types of node: the satellite gateway, the satellite and finally the satellite terminal.
- the broadcasting device according to the invention can advantageously be installed in the satellite gateway so as to take account of the charge rate of the capacity of the air interface of the space segment.
- provision can be made for installing the device in the satellite or in the terminal.
- the optimized information dissemination device can also be applied to an access network of mobile radiocommunication networks in which a satellite access network is inserted between the station controller and the base station or upstream of the data controller. base station or downstream of the base station, in which case the satellite terminal and the mobile terminal could be confused. A spatial segment is therefore implemented.
- the installation of the device can then be done in the base station controller, the satellite gateway, the satellite, the satellite terminal or the base station as desired.
- the device is installed in the base station controller.
- this device can be installed in any type of access network
- the device according to the invention therefore makes it possible to optimize the dissemination of information since the information made available to users is perfectly targeted.
- the device requires a modification of certain nodes of the network which consists of adding a filtering device and possibly adding a device for temporarily storing information flows as well as a retransmission device.
