Description

[Technical field]

[0001] The present invention relates generally to the field of telecommunications, and more particularly to a method for subscribing a mobile device to specific information about its geographic location in a Mobile Edge Computing (MEC) architecture. and systems This is regarding. [Background technology]

[0002] The MEC architecture, defined in the ETSI GS MEC 003 ("European Telecommunications Standards Institute Group Specification Mobile Edge Computing") specification, allows certain computations performed on mobile terminals to be relocated to distributed servers located in a limited geographical zone around the mobile terminal's location and / or centralized in the MEC architecture. This allows mobile terminals, especially those embedded in connected cars, to take advantage of the very large computational power available on these servers, and in particular to display real-time, event-rich high-precision maps of roads that can be shared among connected cars. These servers also provide services to determine the virtual horizon, also called electronic horizon, in order to inform the vehicle of obstacles or events occurring in the near future that are not immediately accessible by the vehicle's built-in sensors. These mapping or electronic horizon services are geo-services in the same way that the data they process depends on the geographical location.

[0003] A mobile device ME of a vehicle that wishes to benefit from such a service must first be identified and registered with the central server SC of the MEC architecture network in a first step E1, corresponding to the sending of a registration message ME1 as shown in Figure 1. Upon receiving this message ME1, the central server SC authenticates the mobile device ME. Once the latter is authenticated, the central server SC checks that the mobile device ME has the necessary rights to use the requested geo-service and authorizes it to do so.

[0004] In a second step E2, the mobile device ME sets up a communication session with a data processing peripheral server SP which instantiates this geo-service for the geographical zone in which the mobile device ME is located.

[0005] Once the communication session has been set up, the mobile device ME sends a message ME3 of subscription to the geoservice to the peripheral server SP in step E3. This message ME3 consists of a list of events likely to be of interest in a region of interest ROI (region of interest), also indicated in this message ME3. The list of events consists, for example, of a value corresponding to a traffic accident and a value corresponding to a traffic jam. Note that the message ME3 may be a secure http type request.

[0006] The next step E4 is for the peripheral server SP to send an acknowledgement message ME4 (here a secure acknowledgement http message) to the mobile device ME.

[0007] When an event occurs that corresponds to the list transmitted by the mobile device ME in step E3, the peripheral server SP transmits, in step E5, a secure message ME5 to inform the mobile device ME of this. Summary of the Invention [Problem to be solved by the invention]

[0008] This procedure, which allows a mobile device to subscribe to a geoservice, induces costly communications between the mobile device and the peripheral server. In fact, step E2 of the https (hypertext transfer protocol secure) connection involves an exchange of about 20 messages, including the opening of the communication session and the TLS (transport layer security) negotiation. These communications also use high quality of service uRLLC (Ultra-reliable and low latency connection) slices to accommodate real-time notifications from the mobile device. These communications are relatively expensive and data-heavy for both the mobile device and the MEC architecture network, due to the limited resources of uRLLC, as well as the computational resources of the network's peripheral servers. Also, the time used by the peripheral server to start the execution of the geoservice is costly.

[0009] Therefore, when a mobile device is a user of geo-services in a MEC architecture network, there is a need to restrict the use of URLC resources and connections on peripheral servers.

[0010] One of the objects of the present invention is to provide a method for subscribing a mobile device to geo-services. and systems and how to transmit mobile device information linked to Geo Services. and systems The present invention aims to remedy at least some of the shortcomings of the prior art by providing a geoservice that is based on a geo-service-based service that is based on a geo-service-based service that is based on a geo-service-based service that is based on a geo-service-based service. [Means for solving the problem]

[0011] For this purpose, the invention relates to a method for subscribing a mobile device to information about at least one type of event, using a notification service linked to the geography of the location. and systemsThe present invention proposes a method for providing a notification service to a data processing peripheral server of a MEC architecture network, the notification service being hosted on a data processing peripheral server of the MEC architecture network, the method comprising: and systems is executed on the mobile device and includes the following steps: sending a registration request message to a central server of said network requesting registration; sending a subscription message addressed to a data processing peripheral server requesting subscription to said at least one event type; receiving a message providing information about said at least one event to said mobile equipment (ME); the registration request message indicates the at least one type of event; The step of sending the subscription message is conditional on there being a preceding step of receiving a notification message that at least one type of event has occurred at the location, and corresponding information is stored in the data processing peripheral server, and the notification message is delivered to the mobile device via a high-speed messaging channel, referred to as a "paging" channel.

[0012] According to the invention, the mobile device will only initiate a subscription procedure with the data processing peripheral server if the data processing peripheral server has information that it should actually provide to the mobile device, i.e. information corresponding to not more than one of the types of events that the mobile device previously registered with the central server. Thus, unnecessary transmission of messages corresponding to the subscription procedure is avoided, saving uRLLC resources of the MEC architecture and the core network and reducing the electricity consumption of the vehicle.

[0013] Subscription method according to the present invention and systems According to an advantageous characteristic, the mobile device indicates in the subscription message a region of interest to which the peripheral server must send the information relating to at least one type of the event.

[0014] In this way, even if the vehicle subscribes to certain types of events at the peripheral server, it is possible to reduce the transmission of information that does not correspond to a geographical zone of pure interest to the mobile device.

[0015] The mobile device is a vehicle communication module and the area of ​​interest corresponds to a route programmed in the vehicle. This use case of the invention is particularly advantageous since the area of ​​interest can be processed dynamically, and a central server and a peripheral server can, for example, be coupled to the location service of the vehicle to track its position and dynamically restrict the broadcast zone of notification messages.

[0016] The subscription method according to the present invention and systems According to another advantageous feature of the present invention, the step of receiving a notification message comprises a sub-step of decoding a data field specific to such an event notification, said specific data field being included in a data field allocated to the core network and present in a "paging record" field of said high-speed messaging channel.

[0017] This particular data field is assigned to, for example, all V2X (short for vehicle-to-everything) services and makes it possible to specify a list of types of events to which a vehicle can subscribe.

[0018] The invention also relates to a method for transmitting information about a type of event to a mobile device by a data processing peripheral server hosting a notification service linked to the geography of a location in a MEC architecture network. and systems The method is carried out in the network and includes the following steps: receiving, by a central server, a registration request message sent from the mobile device, the registration request message including at least an indication of the type of event; said central server sending a message indicating at least said type of event to at least one data processing peripheral server of said network hosting said notification service; said at least one data processing peripheral server verifying the existence of said type of event in its database; sending a message from said at least one data processing peripheral server to at least one base station connected to it for broadcasting a message informing said mobile device of the presence of said type of event on a high speed messaging channel, called a "paging" channel, if said at least one data processing peripheral server contains an event of said type in its database; receiving, by said at least one peripheral server, a subscription message for said type of event sent from said mobile device; sending, by said at least one data processing peripheral server, a message to said mobile device providing information regarding said event.

[0019] Advantageously, said subscription message includes a region of interest and said step of sending an informative message is conditional on the fact that said event is related to said region of interest.

[0020] Also advantageously, in the step of sending by the central server a message indicating at least the type of event, said message indicating at least the type of event is sent only to data processing peripheral servers of the network hosting the notification service whose network coverage corresponds to the current or programmed location of the mobile device.

[0021] Advantageously, the at least one peripheral server is characterized in that it transmits, on a high-speed messaging channel, a message to broadcast to the mobile device notifying the mobile device of the presence of the event only to the base station corresponding to the current or programmed location of the mobile device.

[0022] Also advantageously, said at least one peripheral server transmits said message to said at least one base station only if said event relates to a zone covered by said at least one base station.

[0023] Also advantageously, the step of said at least one peripheral server sending a message informing said mobile device is followed by a step of said at least one peripheral server sending a message to said at least one base station to which it is connected in order to stop broadcasting said notification message on said high-speed messaging channel when said event becomes obsolete or when said mobile device leaves the zone served by said at least one information processing peripheral server. The present invention provides a method for a mobile device to subscribe to a service hosted on at least one data processing peripheral server in a MEC architecture network, comprising the following steps: sending a registration request message to a central server of said network requesting joining; establishing a communication session with the data processing peripheral server; The central server Upon receiving the registration request message including location information of the mobile device, the data processing peripheral server is extracted based on the location information before establishing the communication session with the data processing peripheral server.

[0024] METHOD FOR SENDING INFORMATION ABOUT TYPE OF EVENT TO A MOBILE DEVICE BY A DATA PROCESSING PERIPHERAL SERVER accommodating the present invention and systems The subscription method according to the present invention and systems provides similar benefits. Effect of the Invention

[0025] According to the invention, unnecessary sending of messages corresponding to subscription procedures can be avoided. [Brief description of the drawings]

[Diagram 2] FIG. 2 illustrates, in a preferred embodiment of the invention, a procedure for subscribing a mobile device to events using geoservices according to the invention, and a method for transmitting information about these events to the mobile device according to the invention. [Diagram 3] FIG. 3 illustrates the steps of stopping sending notification messages to a mobile device when the corresponding event becomes stale in this preferred embodiment of the present invention. [Figure 4] FIG. 4 represents, in a variant embodiment of the method according to the invention, a step of stopping the sending of notification messages to a mobile device when the mobile device leaves the corresponding coverage zone. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0027] According to a preferred embodiment of the invention, the mobile device ME subscribes to a location geography linked information notification service, called GeoServices, by the procedure depicted in FIG.

[0028] In a first step E11, the mobile equipment ME, here integrated in the vehicle, sends a message ME11 for registration to the central server SC of the MEC architecture network. This message ME11 consists of an identifier of the mobile equipment ME, values ​​of parameters allowing the evaluation of the processing and communication capabilities of the vehicle, an identifier of the geoservice to which the mobile equipment ME is registered, and one or more values ​​corresponding to the type of events for which the mobile equipment wants to be notified. These events correspond for example to works, accidents, slow vehicles, traffic jams, etc. The message ME11 is for example based on the https protocol.

[0029] On receiving this message ME11, the central server SC authenticates the mobile device ME and then verifies that the mobile device ME has the necessary capabilities to use the requested geo service and authorizes it to be used in the data-processing peripheral server that instantiates it. The central server SC in particular sends a message ME12 in step E12 to the first peripheral server SP1 and a message ME13 in step E13 to the second peripheral server SP2 after step E11, which correspond to the peripheral servers that instantiate the geo service and whose operator has granted access to the mobile device ME in particular according to its subscription. The messages ME12 and ME13 are for example based on the https or MQTT (short for message queuing telemetry transport) protocol of the secure layer. As a variant, if the central server SC interfaces with the location service of the mobile device ME, it sends a message immediately after the first step E11 only to the data-processing peripheral server that corresponds to the vehicle's rough position. The vehicle can thus benefit from the geo service even if it is moving within a predefined distance zone.

[0030] Messages ME12 and ME13 each contain an identifier of the mobile equipment ME and a list of values ​​corresponding to the types of events for which notification is desired, the identifier of the mobile equipment being derived from its IMEI (short for International Mobile Equipment Identity) according to the standards of cellular networks. Steps E12 and E13 are followed by steps E14 and E15 respectively, which may for example be executed simultaneously.

[0031] Step E14 consists in the peripheral device SP1 verifying that one or more events of the type included in the list received in step E12 are stored in its database. In this exemplary embodiment of the invention, it is assumed that at least one of these events is stored in the database of the peripheral server SP1, for example an accident in the geographical zone covered by this peripheral server.

[0032] Likewise, step E15 consists in verifying by the peripheral server SP2 that it has stored in its database one or more events of the type included in the list received in step E13. In this exemplary embodiment of the invention, it is assumed that the peripheral server SP2 does not have any corresponding events stored in its database, so that it stores the list received in step E13 but does not initiate a notification procedure with the mobile device ME.

[0033] After the step E14, the peripheral server SP1 sends a message ME16 to the first base station SB1 in a step E16 and a message ME18 to the second base station SB2 in a step E18. These messages use, for example, the https protocol.

[0034] These base stations SB1, SB2 correspond to radio transceiver stations to which the peripheral server SP1 is connected. In a variant embodiment, if the peripheral server SP1 is linked to the location services of the mobile device ME, the peripheral server SP1 sends messages immediately after step E14 only to those base stations which correspond to the vehicle's general position and / or to events whose geographical extent is stored in the peripheral server SP1's database. Thus, the vehicle can benefit from geo-services even if it is moving within a predefined distance zone, and will only be notified of events related to this predefined distance zone.

[0035] Messages ME16 and ME18 each include an identifier of the mobile device ME and one or more values ​​corresponding to a type of event stored in the database of the peripheral server SP1 and included in the list received in step E12 (here, values ​​corresponding to an accident).

[0036] On receiving the message ME16, the base station SB1 transmits a notification message ME17 to the mobile device ME in step E17. The transmission of this notification message ME17 uses a fast messaging channel called the “paging” channel. To do so, the base station SB1 appends a specific data field “V2X” called “paging record” of a “paging record list” to an LTE (short for long term evolution) subfield called “paging occasion (PO)” that corresponds to the identifier of the mobile device. The “paging record list” is a list of data intended for the mobile devices connected to the base station SB1.

[0037] Next, the data field "Paging Record" is composed of the following data fields: - "UE-identity" which is an encoded value of the mobile equipment ME's identifier. A "cn-domain" that can take one of the following values: "ps" for packet switched, "cs" for circuit switched, or a new value "V2X" that is used for notification to the mobile device according to the present invention. The selected value "cn-domain" corresponds to a message (incoming data communication, incoming voice communication, or notification message) that is intended for the mobile device according to the present invention. In this exemplary embodiment of the present invention, the "cn-domain" field takes the value "V2X". · Specific data field "V2X" The specific data field "V2X" codes the type of event, which in this exemplary embodiment corresponds to an accident. More generally, the content of this field is a table that is present in the database of the peripheral server associated to the base station in question and that has as its entry all events of potential interest to the mobile device with the identifier "UE-identity", i.e. that forms part of the registration message ME11. Thus, if at the time of the registration message ME11 the vehicle indicated that it is interested in four types of events {accident, animals on the road, construction works, traffic jam}, the peripheral server SP1 only has events of type accident in its database, and therefore the field "V2X" will take the value {accident}.

[0038] The message ME17 corresponding to this particular data field "V2X" is periodically signaled to the mobile equipment ME, which typically wakes up every 1.048 seconds (s) to read the "paging occasion" field. This period of 1.048 corresponds to a discontinuous reception cycle, called DRX, which allows the mobile equipment ME not to continuously monopolise radio resources to listen to the "paging" channel when it is in standby mode. Thus, upon reception of the message ME17 in this step E17, the mobile equipment ME decodes this particular field "V2X" of the message ME17 transmitted via the "paging" channel and ascertains that the geo-services have recorded an event of type "accident" that is likely to correspond to its region of interest ROI.

[0039] Likewise, upon receipt of the message ME18, the base station SB2 sends, in step E19, a notification message ME19 to the mobile equipment ME. The sending of this notification message ME17, containing the type of event corresponding to the accident and the identifier of the mobile equipment, uses the "paging" channel, as in step E17.

[0040] In this exemplary embodiment of the invention, it is assumed that the mobile equipment ME is located within the coverage of base station SB1 and has therefore received the notification message ME17.

[0041] Then, in the next step E20, a communications session is set up with the data processing peripheral server SP1 in order to recover information relating to the event of type "accident" just notified. This step E20 is carried out in a similar way to step E2.

[0042] In a next step E21, the mobile device ME sends a subscription message ME21 subscribing to an event of type "accident". This message ME21 contains the identity of the mobile device, a value corresponding to the "accident" type of event and a corresponding region of interest ROI (which in this exemplary embodiment of the invention corresponds to the programmed route of the vehicle).

[0043] It should be noted that this message ME21 does not contain any values ​​corresponding to types of events other than "accident", since the mobile device ME has been able to determine through the notification message ME17 that there are no other types of events stored in the database of the peripheral server SP1. Furthermore, the mobile device ME sends a join message only to the peripheral server SP1, since this is the one that corresponds to its geographical location.

[0044] If in the meantime a new type of event occurs in the database of the server SP1 (for example an animal on the road is detected), the "V2X" field of the "paging record" of the mobile device ME that is interested in this type of event is updated and the mobile device ME will be informed of this new type of event at the next transmission of a high speed message called paging message. The mobile device ME receives a notification on this channel with the "V2X" field set to {accident, animal on the road}. After receiving this notification, the mobile device can include this new type of event in its next subscription message to the server SP1.

[0045] Upon receiving the message ME21, the peripheral server SP1 sends an acknowledgement message ME22 to the mobile device ME in step E22. The peripheral server SP1 then checks whether the stored event is within the region of interest ROI of the vehicle, within which it is assumed in this exemplary embodiment the accident occurred.

[0046] The next step E23 is then the sending by the peripheral server SP1 of a message ME23 to the mobile device ME containing information related to the accident, in particular the location of the accident.

[0047] It should be noted that depending on the occurrence of events handled by the geoservice, more or less message exchanges may be required in the MEC architecture network when using the present invention. If the accident did not occur within the vehicle's area of ​​interest, step E23 is not performed and, in this case, the periphery server does not send the corresponding information to the vehicle. · If another type of event occurs within the zone served by the peripheral server SP1 (e.g. construction), messages ME17 and ME19 contain in the specific data field “V2X” two values ​​corresponding to the types “accident” and “construction”. If another event of a type included in the list received in step E13 occurs within the zone served by the peripheral server SP2, the peripheral server SP2 sends a message to the relevant base stations which inform the mobile equipment ME of the presence of this other event by means of a "paging" channel. The latter receives this notification only when it enters the coverage of one of these base stations.

[0048] It should be noted that the order of execution of the steps is different in a variant embodiment in which, in the last case, another event occurs in the zone served by the peripheral server SP2, the central server SC sends a message containing the event of interest for the mobile device only to the peripheral server SP1 serving the zone in which the vehicle is located. In fact, in this version it is necessary to wait for the vehicle to enter the zone served by the peripheral server SP2. For this, the central server SC, informed by the location service of the movement of the vehicle, sends a message containing the event of interest to the peripheral server SP2, which in turn sends messages to the base stations to which it is connected, which in turn inform the mobile device ME. If the peripheral server SP2 is connected to the location service, it preferably sends messages only to the base station at which the mobile device ME is located, in order to further save network and radio resources, and possibly only if this other event is located in the zone covered by this base station.

[0049] 3, the additional steps E30 to E33 are provided in case the peripheral server SP1 does not store in its database the event for which the mobile device ME has requested to receive notification. In an example of use of the invention, it is assumed for example that a vehicle involved in an accident corresponding to the event notified in step E17 has left the road.

[0050] Then, at step E30, the event corresponding to this accident is deleted in the database of the peripheral server SP1.

[0051] In the following steps E32 and E33, the peripheral server SP1 sends messages ME32 and ME33 to the base stations SB2 and SB1, respectively, requesting them to stop inserting "V2X" messages corresponding to events of type "accident" in the "paging" channel to the mobile device ME. The base stations SB2 and SB1 then erase this notification request from their databases, thus freeing up their radio and memory resources. It should be noted that the peripheral server does not erase in any way the data linked to the mobile device ME for the geo service, unless the mobile device unsubscribes from this geo service. Thus, in case of the occurrence of a new event of interest to the mobile device ME, the peripheral server SP1 can resend messages similar to the messages ME16 and ME18 to its attached base stations.

[0052] In an alternative embodiment in which the peripheral server SP1 is linked to a location service, the peripheral server SP1 sends a message via a "paging" channel only to the base station under whose coverage the mobile device ME is located, requesting it to stop notifying the mobile device ME.

[0053] The mobile equipment ME is informed of the disappearance of the incident by the absence of the “V2X” data field of the “Paging” channel in the next discontinuous reception cycle DRX. On the other hand, if the next “V2X” data field transmitted by the “Paging” channel contains a new type of event, e.g. corresponding to the work “work”, contained in the message ME11, the mobile equipment “ME” can renew its subscription request to receive the corresponding information by sending a new message similar to the message ME21.

[0054] With reference to FIG. 4, in a variant of this embodiment in which the central server SC interfaces with the location services of the mobile device ME, additional steps E40 to E43 are provided.

[0055] Indeed, in this variant embodiment, in order to save radio resources, the central server SC releases the resources allocated to the mobile device ME in the peripheral server when the mobile device ME leaves the zone provided by this peripheral server. Of course, when the central server SC detects that the mobile device ME has returned to the zone provided by this peripheral server, these resources are reallocated by a message sent from the central server SC to the peripheral server.

[0056] Thus, in a step E40, the central server SC detects the departure of the mobile device ME from the zone provided by the peripheral server SP1.

[0057] In a next step E41, the central server SC sends a message ME41 to the peripheral server SP1, which message ME41 notifies that the mobile device ME has changed the peripheral server of attachment.

[0058] On receiving the message ME41, the peripheral server SP1 sends a message ME42 in step E42 to the base station SB2 and a message ME43 in step E43 to the base station SB1 before deleting from its memory the data assigned to the mobile device ME relating to geo-services. These messages ME42 and ME43, like the messages ME32 and ME33, request the mobile device ME to stop being notified by the "paging" channel of types of events that are of interest to the mobile device ME. The base stations SB2 and SB1 therefore free up radio and memory resources by deleting this notification request from their databases.

[0059] In an alternative embodiment in which the peripheral server SP1 is linked to a location-based service, the peripheral server SP1 sends a message via a "paging" channel requesting the mobile device ME to stop notifications only to base stations under whose coverage the mobile device ME was located.

[0060] It should be noted that in the main variant embodiment, the resources allocated to event notification to the vehicle are deterministically released in the perimeter server and in the general base station only upon deregistration of the vehicle from the geo service.

[0061] Furthermore, other variants of the invention are of course conceivable, sometimes even combined. For example, in a variant, the central server SC interfaces with the location service of the mobile device ME, but instead of allocating resources for the mobile device ME in different peripheral servers dynamically depending on the location of the mobile device, it allocates these resources only once after a registration message ME11 in all peripheral servers serving the region of interest of the mobile device ME, for example a programmed route. In this case, the registration message ME11 contains the region of interest ROI of the mobile device ME. In this or another variant, the peripheral server is, for example, interfaced with a very accurate location service, and can monopolise the mobile device ME's resources for geo-services only in the base station to which the mobile device ME is connected.

[0062] Finally, notification messages using the paging channel can be addressed to a single mobile device or a group of mobile devices (e.g., a group of vehicles subscribed to the same geo-service). In this case, the identity associated with and transmitted on the notification channel is a collective identity. In this case, a single registration message is transmitted to a central server for this set of vehicles, for example via a fleet management server.
