Description

PROCEDE DE RESERVATION POUR COMMUNICATION DANS UN RESEAU DE COMMUNICATION MOBILE RESERVATION METHOD FOR COMMUNICATION IN A MOBILE COMMUNICATION NETWORK
L'invention concerne le domaine des procédés de réservation pour communication dans un réseau de communication mobile, ainsi que les systèmes et les serveurs pouvant mettre en œuvre lesdits procédés de réservation pour communication. Lorsqu'une personne est amenée à utiliser un procédé de réservation pour communication au sein d'un réseau de communication mobile, souvent elle aimerait se voir garantir une qualité de service minimum lui permettant de se retrouver dans des conditions analogues à celles qu'elle peut avoir dans son environnement habituel au sein d'un réseau de communication fixe.The invention relates to the field of reservation methods for communication in a mobile communication network, as well as systems and servers that can implement said reservation processes for communication. When a person is required to use a reservation method for communication within a mobile communication network, often she would like to be guaranteed a minimum quality of service allowing her to find herself in conditions similar to those she can have in his usual environment within a fixed communication network.
Selon un art antérieur, par exemple décrit dans la demande de brevet européen EP 1458148 ou bien dans la demande de brevet européen EP 1324628, il est connu, dans le contexte des réseaux de communication mobile dits « ad-hoc », c'est-à-dire dans le contexte de réseaux mobiles constitués par d'autres terminaux mobiles, d'abord de réaliser des mesures préalables de qualité de service, ensuite de réserver plusieurs chemins potentiels le long desquels les données de la communication sont susceptibles d'être acheminées, enfin de libérer les nombreuses ressources réservées qui ne seront finalement pas utilisées.According to a prior art, for example described in the European patent application EP 1458148 or in the European patent application EP 1324628, it is known, in the context of so-called "ad-hoc" mobile communication networks, that is, in the context of mobile networks constituted by other mobile terminals, first of all to carry out prior measures of quality of service, then to reserve several potential paths along which the data of the communication are likely to be conveyed Finally, to release the many reserved resources that will ultimately not be used.
Un inconvénient de cei art antérieur est d'être extrêmement lourd et complexe. En effet, la réservation anticipée de ressources, auprès de points d'accès mobiles et de manière tout à fait provisoire, est particulièrement difficile à mettre en œuvre si l'on veut effectivement garantir un seuil minimum de qualité de service au cours du déplacement de l'utilisateur du terminal mobile participant à une communication mobile, notamment lors du changement de connexion, d'un point d'accès à un autre point d'accès.A disadvantage of this prior art is that it is extremely heavy and complex. Indeed, the advance reservation of resources, with mobile access points and in a very temporary way, is particularly difficult to implement if we want to effectively guarantee a minimum threshold of quality of service during the trip. the user of the mobile terminal participating in a mobile communication, in particular when changing the connection, from an access point to another access point.
L'invention se propose de résoudre ce problème au regard d'un type de déplacement de l'utilisateur du terminal mobile qui n'est pas considéré dans l'art antérieur, à savoir le cas d'un déplacement d'un utilisateur de terminal mobile le long d'un trajet temporellement et spatialement prédéterminé avec une assez bonne précision, par exemple un voyage en train sans accident et sans retard excessif. Ainsi, connaissant l'évolution spatiale et temporelle de l'utilisateur de manière anticipée avec une assez bonne précision, il deviendra possible de réserver de manière ferme, auprès de points d'accès fixes dans le réseau, les ressources nécessaires à maintenir un seuil minimum de qualité de service. Il est intéressant de maintenir un seuil minimum de qualité de service, car si toute chute de qualité de service lors d'un changement de connexion est dommageable en soi pour l'utilisateur, une micro-coupure l'est encore plus à cause de du fait qu'il faut remettre en place l'ensemble de la session. Puisque les points d'accès fixes constituent souvent des goulots d'étranglement dans le réseau, ce sont par exemple des stations de base, il est particulièrement intéressant de pouvoir réserver à bon escient des ressources auprès de ces points d'accès fixes de manière anticipée, le risque de ne pas avoir satisfaction en cas de demande trop tardive étant trop élevé. Une réservation ferme signifie que l'on réserve les ressources que l'on a effectivement l'intention d'utiliser et non pas un grand nombre de ressources dont on sait à l'avance que la plupart ne seront jamais utilisées comme dans le cas des différents chemins potentiels de l'art antérieur alors qu'un seul des chemins potentiels réservés sera effectivement utilisé. Malgré la prise d'une certaine marge de sécurité en termes de fenêtre temporelle de réservation, c'est-à-dire de période de réservation, de préférence, lorsque des ressources auprès de plusieurs points d'accès fixes successifs le long du trajet de l'utilisateur seront réservées, pour un moment donné futur d'utilisation envisagé, des ressources auprès d'un seul point d'accès fixe seront réservées, même si un certain recouvrement des fenêtres temporelles de réservation de ressources auprès de deux points d'accès fixes consécutifs le long du trajet reste possible. Les points d'accès fixes successifs sont de préférence consécutifs, auquel cas notamment les fenêtres temporelles correspondantes seront également consécutives ; des points d'accès fixes successifs peuvent toutefois ne pas être consécutifs, notamment dans le cas où l'utilisateur n'est intéressé par une qualité de service minimum que pendant des périodes disjointes, par exemple deux conférences vidéo séparées par une période d'inactivité. De préférence, i! n'y a recouvrement des fenêtres temporelles de réservation de ressources qu'entre deux fenêtres consécutives ; il n'y a alors jamais recouvrement de trois ou de plus de trois fenêtres temporelles de réservation de ressources : dans ce cas préférentiel, à un instant donné, des ressources ne peuvent être réservées qu'auprès de deux points d'accès fixes au maximum.The invention proposes to solve this problem with regard to a type of displacement of the user of the mobile terminal which is not considered in the prior art, namely the case of a displacement of a terminal user. mobile on along a temporally and spatially predetermined path with a fairly good accuracy, for example a trip by train without accident and without excessive delay. Thus, knowing the spatial and temporal evolution of the user in advance with a fairly good accuracy, it will become possible to firmly reserve, with fixed access points in the network, the resources necessary to maintain a minimum threshold quality of service. It is interesting to maintain a minimum threshold of quality of service, because if any drop in quality of service during a change of connection is damaging in itself for the user, a micro-cut is even more because of the the fact that the entire session needs to be reinstated. Since fixed access points are often bottlenecks in the network, for example, they are base stations, it is particularly interesting to be able to reserve resources with these fixed access points in a timely manner. , the risk of not being satisfied in case of too late demand being too high. A firm reservation means reserving the resources that we actually intend to use and not a large number of resources known in advance that most will never be used as in the case of different potential paths of the prior art whereas only one of the reserved potential paths will actually be used. Despite taking a certain safety margin in terms of the reservation window, that is to say the reservation period, preferably when resources from several successive fixed access points along the route of the user will be reserved, for a given future time of use envisaged, resources from a single fixed access point will be reserved, even if some recovery time windows of resource reservation from two access points consecutive fixtures along the path remains possible. The successive fixed access points are preferably consecutive, in which case the corresponding time windows will also be consecutive; successive fixed access points may however not be consecutive, especially in the case where the user is interested in a minimum quality of service that during disjointed periods, for example two video conferences separated by a period of inactivity. Preferably, i! resource time windows only overlap between two consecutive windows; there is never any recovery of three or more time windows of resource reservation: in this preferential case, at a given time, resources can be reserved only for two fixed access points at the most .
Selon l'invention, il est prévu un procédé de réservation pour communication dans un réseau de communication mobile comprenant des points d'accès au réseau de communication mobile et des terminaux mobiles destinés à être connectés aux points d'accès, caractérisé en ce que pour un terminal mobile destiné à suivre un trajet prédéterminé comportant une liste de points d'accès fixes, on réserve de manière ferme et anticipée, auprès de plusieurs points d'accès fixes successifs de la dite liste, les ressources nécessaires à maintenir un seuil minimum de qualité de service pendant une communication dudit terminal mobile lors d'un changement de connexion dudit terminal mobile, d'un desdits points d'accès fixe à un autre desdits points d'accès fixes. La liste de points d'accès fixes peut être prédéterminée. De préférence, l'étape de réservation est précédée par une étape de détermination d'une liste de points d'accès fixes situés le long d'un trajet prédéterminé d'un terminal mobile.According to the invention, there is provided a reservation method for communication in a mobile communication network comprising access points to the mobile communication network and mobile terminals intended to be connected to the access points, characterized in that for a mobile terminal intended to follow a predetermined path comprising a list of fixed access points, the resources necessary to maintain a minimum threshold of the number of fixed access points in a fixed and anticipated manner are reserved at several successive fixed access points of said list; quality of service during a communication of said mobile terminal upon a connection change of said mobile terminal from one of said fixed access points to another of said fixed access points. The list of fixed access points can be predetermined. Preferably, the reservation step is preceded by a step of determining a list of fixed access points located along a predetermined path of a mobile terminal.

Selon l'invention, il est également prévu un serveur d'application pour réseau de communication mobile comprenant des points d'accès au réseau de communication mobile et des terminaux mobiles destinés à être connectés aux points d'accès, apte à réserver, à partir d'une liste de points d'accès fixes situés le long d'un trajet prédéterminé d'un terminal mobile, de manière ferme et anticipée, de la ressource, auprès de plusieurs points d'accès fixes successifs de ladite liste, de manière à garantir en permanence audit terminal mobile une qualité de service minimum pendant une communication dudit terminal mobile lors d'un changement de connexion dudit terminal mobile, d'un desdits points d'accès fixe à un autre desdits points d'accès fixes.According to the invention, there is also provided an application server for a mobile communication network comprising access points to the mobile communication network and mobile terminals intended to be connected to the access points, able to reserve, from a list of fixed access points located along a predetermined path of a mobile terminal, in a firm and anticipated manner, of the resource, at several successive fixed access points of said list, so as to permanently guaranteeing said mobile terminal a minimum quality of service during a communication of said mobile terminal during a connection change of said mobile terminal, from one of said fixed access points to another of said fixed access points.
L'invention sera mieux comprise et d'autres particularités et avantages apparaîtront à l'aide de la description ci-après et des dessins joints, donnés à titre d'exemples, où :The invention will be better understood and other features and advantages will become apparent from the following description and accompanying drawings, given by way of example, where:

De préférence, l'étape de réservation réserve de manière anticipée de la ressource auprès de plusieurs points d'accès successifs de ladite liste respectivement pendant des fenêtres temporelles successivement décalées dans le temps. Cela permet un mode un mode de réservation réalisant un bon compromis entre la sécurité de la réservation, la réservation faite bien à l'avance a de bonnes chances d'être acceptée, et l'efficacité de la réservation, la réservation est effectuée sur une fenêtre temporelle relativement peu étendue pendant laquelle la ressource réservée sera effectivement utilisée selon toutes probabilités. Les fenêtres temporelles ne présentent avantageusement pas de recouvrement entre elles.Preferably, the reservation step reserves the resource in advance of several successive access points of said list respectively during time windows successively shifted in the time. This allows a mode a reservation mode achieving a good compromise between the security of the reservation, the reservation made well in advance is likely to be accepted, and the efficiency of the reservation, the reservation is made on a relatively small time window during which the reserved resource will actually be used in all likelihoods. The time windows advantageously have no overlap between them.
La figure 1 représente schématiquement un exemple de diagramme temporel mettant en évidence l'étape de réservation de ressource auprès de plusieurs points d'accès fixes situés le long d'un trajet prédéterminé d'un terminal mobile, conformément au procédé de réservation pour communication selon l'invention. Au cours du temps, représenté par un axe temporel 1 , l'utilisateur 9 va traverser successivement plusieurs cellules 2, 3 et 4. Autour du passage de la cellule 2 à la cellule 3, se trouve une zone de changement de connexion 5. Autour du passage de la cellule 3 à la cellule 4, se trouve une zone de changement de connexion 6. En début de déplacement ou alors que l'utilisateur est en déplacement dans une autre cellule, c'est-à-dire avant et de préférence bien avant son arrivée au niveau de la zone de changement de connexion 5, pendant une fenêtre temporelle 7 située au niveau du temps d'arrivée prévu de l'utilisateur sur la zone de changement de connexion 5 et incluant aussi une période de temps située avant le temps d'arrivée prévu de l'utilisateur sur la zone de changement de connexion 5, les ressources nécessaires à la garantie d'un seuil minimum de qualité de service sont réservées auprès du point d'accès fixe associé à la celluleFIG. 1 diagrammatically represents an exemplary timing diagram highlighting the resource reservation step with several fixed access points located along a predetermined path of a mobile terminal, in accordance with the reservation method for communication according to the invention. Over time, represented by a time axis 1, the user 9 will successively cross several cells 2, 3 and 4. Around the passage from cell 2 to cell 3, there is a connection change zone 5. Around from the passage of the cell 3 to the cell 4, there is a connection change zone 6. At the beginning of displacement or while the user is moving in another cell, that is to say before and preferably long before it arrives at the connection change zone 5, during a time window 7 located at the expected arrival time of the user on the connection change zone 5 and also including a period of time before the expected arrival time of the user on the connection change zone 5, the resources required to guarantee a minimum quality of service threshold are reserved for the fixed access point associated with the cell

De même, pendant une fenêtre temporelle 8 située au niveau du temps d'arrivée prévu de l'utilisateur sur la zone de changement de connexion 6 et incluant aussi une période de temps située avant le temps d'arrivée prévu de l'utilisateur sur la zone de changement de connexion 6, les ressources nécessaires à la garantie d'un seuil minimum de qualité de service sont réservées auprès du point d'accès fixe associé à la cellule 4. De préférence, l'étape de réservation réserve de manière anticipée de la ressource auprès d'au moins cinq points d'accès successifs de ladite liste, voire auprès d'au moins dix, ce qui permet de diminuer encore la probabilité de se voir refuser la réservation.3. Similarly, during a time window 8 located at the expected arrival time of the user on the change of connection zone 6 and also including a period of time before the expected arrival time of the user on the connection change zone 6, the resources necessary to guarantee a minimum threshold of quality of service are reserved with the fixed access point associated with the cell 4. Preferably, the reservation step reserves so anticipated resource at least five points successive accesses of said list, or even at least ten, which further reduces the probability of being denied the reservation.
De préférence, l'étape de réservation n'est pas précédée par une étape de mesure de qualité de service, ce qui rend le procédé de réservation pour communication selon l'invention encore plus simple.Preferably, the reservation step is not preceded by a quality of service measurement step, which makes the reservation process for communication according to the invention even simpler.
La figure 2 représente schématiquement un exemple de système comprenant un réseau de communication mobile 10, un réseau cœur de type Internet 20, un réseau applicatif 30 comprenant des moyens mettant en œuvre l'étape de réservation, conformément au procédé de réservation pour communication selon l'invention. Le réseau de communication mobile 10 comprend plusieurs points d'accès fixes, par exemple stations de base dans un réseau de deuxième génération ou contrôleurs de réseau radio (« radio network controller » en langue anglaise) dans un réseau de troisième génération, deux points d'accès fixes 1 1 et 12 seulement étant représentés sur la figure 1 pour des raisons de simplicité. De préférence, le réseau de communication mobile est au moins de la troisième génération, éventuellement au moins de la quatrième génération. Un terminal mobile 40 se déplace d'une première cellule rattachée au point d'accès fixe 1 1 vers une deuxième cellule rattachée au point d'accès fixe 12. Le réseau de communication mobile 10 est relié au réseau cœur de type Internet 20 lui-même relié au réseau applicatif 30. Le réseau applicatif 30 comprend une serveur d'application 31 chargé de gérer le procédé de réservation pour communication selon l'invention au niveau applicatif. Le serveur d'application 31 est relié à un serveur de réservation de voyage 32, à un serveur d'envoi de vidéo 33, à une base de données 34 contenant les informations relatives aux trajets correspondant aux voyages que peut effectuer l'utilisateur du terminal mobile 40, à un serveur de localisation 35. Le serveur de réservation de voyage 32 réserve un voyage à un moment donné pour un utilisateur de terminal mobile 40 le long d'un trajet donné. Le serveur d'envoi de vidéo 33 envoie au moment voulu par l'utilisateur du terminal mobile 40 la vidéo qu'il demande. La base de données 34 est capable d'indiquer en fonction du voyage choisi à quels points d'accès fixes l'utilisateur du terminal mobile 40 est censé être rattaché et à quel moments il est censé y être rattaché. Le serveur de localisation 35 peut constituer une garantie supplémentaire, car sachant au cours du temps où l'utilisateur du terminal mobile 40 se trouve effectivement, il peut aider le serveur d'application 31 à moduler ou à corriger les informations fournies par la base de données 34. A l'aide des informations fournies par le serveur de réservation de voyage 32, par la base de données 34 et éventuellement par le serveur de localisation 35, c'est le serveur d'application 31 qui réserve de manière anticipée les ressources auprès des points d'accès fixes 1 1 et 12 pour le compte du terminal mobile 40 et non pas le terminal mobile 40 lui-même.FIG. 2 diagrammatically represents an exemplary system comprising a mobile communication network 10, an Internet-type core network 20, an application network 30 comprising means implementing the reservation step, in accordance with the reservation method for communication according to the 'invention.

The envisaged communications are rather of broadcast type (" broadcast "in English) than peer-to-peer.
De préférence, l'application est une application temps réel. Ce peut être par exemple une opération de transaction sur un marché boursier. Ce type d'application rend toute coupure même courte dans le déroulement de l'application extrêmement pénible pour l'utilisateur du terminal mobile. Ce phénomène est encore plus marqué lorsque l'application implique un transfert de vidéo à destination de l'utilisateur du terminal mobile. De préférence, l'application est une application transmettant de la vidéo en temps réel. Ce peut être par exemple une conférence vidéo ou une visualisation d'émission télévisée en direct.Preferably, the application is a real-time application. It may be for example a transaction transaction on a stock market. This type of application makes any break even short in the course of the application extremely painful for the user of the mobile terminal. This phenomenon is even more marked when the application involves a transfer of video to the user of the mobile terminal. Preferably, the application is an application transmitting video in real time. This may be for example a video conference or live TV viewing.
Un exemple préférentiel de paramètre représentatif de la qualité de service concerne la bande passante, le seuil minimum de qualité de service correspondant à une bande passante minimum garantie. D'autres paramètres représentatifs de la qualité de service sont également envisageables. A preferred example of a parameter representative of the quality of service relates to the bandwidth, the minimum threshold of quality of service corresponding to a guaranteed minimum bandwidth. Other parameters representative of the quality of service are also conceivable.
