Description

SYSTEM FOR PROVIDING INFORMATION ABOUT A GEOGRAPHICAL AREA WITHIN A NETWORK AND METHOD THEREOF

TECHNICAL FIELD

The present disclosure relates generally to a field of data communication. More particularly, it relates to systems and methods for sharing information about geographical area within the network.

BACKGROUND

Traffic and road perception for a vehicle has become of paramount importance in the automotive industry. This is not only important for Autonomous Driving, AD, vehicles, but is also important for vehicles with Automated Driving Assistance Systems, ADAS. Industries are investing in sensor based systems to increase this perception. The sensor based systems provide road related inputs which are then combined and fused with vehicle's own sensors to increase the perception. In many scenarios, the vehicles also share road related information with other vehicles as outlined, for example by the European Telecommunications Standards Institute, ETSI, standard for Collective Perception Message, CPM, and by Society of Automotive Engineers, SAE, standard for Sensor Data Sharing Message, SDSM. These standards historically are based on short range broadcast technology, i.e. vehicles in a surrounding area may receive vehicle broadcast information about objects detected by other vehicles and may enhance their perception.

SUMMARY

Though short range communication technologies are widely known for sharing information over a short range, however, not many vehicles are equipped with short range devices. Furthermore, there exists several variants of short range technology fundamentally different, e.g. ITS-G5, DSRC, LTE-PC5 and soon to come NR-PC5, and for interoperability, devices must support same technology in every protocol detail, this makes it complicated and costly to maintain interoperability. Additionally, the short range broadcast system may only benefit vehicles which are in the vicinity of a broadcasting entity. Regarding sustainability, the short range broadcast technology may not be preferred since it keeps on emitting information without considering the importance of the information and this thus lead to power wastage and creating interference. There is also an issue of trust and security. It is difficult for receivers for example, vehicles of the road information to know that detected objects which are reported have been correctly identified and classified.

Therefore, there is a need for an improved system for sharing secure road information with better precision and/or accuracy.

It is therefore an object of the present disclosure to provide a system and a method for sharing road information using cellular networks to mitigate, alleviate, or eliminate all or at least some of the above-discussed drawbacks of presently known solutions.

Some embodiments disclosed herein have one or more of the following advantages: - With the proposed solution the information about detected objects over a particular geographical area may be obtained by consumers which are further away from the detected object. Having such information, the consumer may get traffic information over a determined geographical area and may take any early actions.

- The proposed solution uses unicast for transmitting the information over a cellular network. The proposed solution provides a scalable and distributed database structure which organizes the information in a tile system to enable presentation of objects in a specific area. All consumers that can use a cellular network will be able to make use of the information presented in the tile.

- The database in the proposed system may combine multiple information sources for example producers from different locations and share information which can be used to make conclusions on the traffic situation in a specific geographical area. This is not individual producers and consumer able to do. Thus the proposed solution provides a scalable and dynamic arrangement of producers, databases and consumers to enhance a collaborative perception of the information.

- Compared with available solutions, the proposed solution offers end-to-end unicast connections between consumer's producers. The end-to-end connectivity between the consumer and the producer increases the security for consumers since it allows protection between the communicating end points using standard IP based technology, such as TLS. It can thereby be secured that the consumers do not receive tampered data from databases. Through this end-to-end connectivity, the consumers may now receive the data directly from the source or the producer.

- The proposed solution may also provide an option of receiving raw data to the consumer, e.g., high resolution video or point cloud. The raw data may comprise unfiltered or unprocessed information about objects captured by the producer. The consumer may directly process the raw data and analyze it for road information predictions.

- This possibility of accessing fixed/infrastructure detection modules or sensors improves the experience of the consumer. These sensors gives an accurate position, compared with vehicle sensors. Vehicle sensors characteristically give a position and then as the vehicle moves, i.e., sends a position during movement, and hence the position information becomes less accurate than a position from a fixed/infrastructure sensor.

Other advantages may be readily apparent to one having skill in the art. Certain embodiments may have none, some, or all of the recited advantages.

The wireless communication system 100 may comprise and/or interface with any type of communication, telecommunication, data, cellular, and/or radio network or other similar type of system. The wireless communication system 100 may be configured to operate according to specific standards or other types of predefined rules of procedures. Thus, the wireless communication system 100 may implement communication standards, such as, but are not limited to, global system for mobile communications, GSM, universal mobile telecommunications system, UMTS, long term evolution, LTE, new radio, NR, and/or other suitable 2G, 3G, 4G, 5G, or 6G standards, wireless local area network, WLAN, standards such as, IEEE 802.11 standards, and/or any other appropriate wireless communication standards, such as, worldwide interoperability for microwave access, WiMax, Bluetooth, Z-Wave and/or ZigBee standards.

For simplicity, as depicted in FIG. 1, the wireless communication system 100 comprises a system 1000, a network node 104, and a network 106. The system 1000 and the network node 104 operate together in order to provide wireless connections in the wireless communication system. The wireless communication network 106 may comprise one or more backhaul networks, core networks, IP networks, public switched telephone networks, PSTNs, packet data networks, optical networks, wide-area networks, WANs, local area networks, LANs, wireless local area networks, WLANs, wired networks, wireless networks, metropolitan area networks, and other networks to enable communication between devices (for example, wireless devices and network node).

In an example, the network node 104 refer to equipment capable, configured, arranged, and/or operable to communicate directly or indirectly with the container-based computer system 200, 400 and/or with other network nodes or equipment in the wireless communication system 100 to enable and/or provide wireless access to the system 1000 and/or to perform other functions (for example, administration) in the wireless communication system 100. Examples of the network node 104 may include, but are not limited to, access points, APs (for example, radio access points), base stations, BSs (for example, radio base stations, nodeBs, evolved NodeBs, eNBs, new radio, NR, nodes (gNBs), or the like). The BSs may be categorized based on an amount of coverage the BSs provide (or, stated different, their transmit power level) and may then also be referred to as femto BSs, pico BSs, micro BSs, macro BSs. The BS may be a relay node or a relay donor node controlling a relay.

The wireless communication system 100 hosts large scale applications.

In an example, when the short range communication technologies are used for broadcasting road related information, the vehicle may encounter certain challenges in terms of adequate short range device support in the vehicle and problem with reception of information due to the reach of short range communication. This may result in that complete data may not be received by the vehicle. Thus there is a huge risk of incomplete and erroneous data.

FIG. 4 is an exemplary flowchart illustrating example steps for a method 4000 implemented in the system 1000 for sharing the information about the geographical area within the network 106.

The order in which the method 4000 is described is not intended to be construed as a limitation, and any number of the described method blocks may be combined in any order to implement the method 4000 or alternate methods. Additionally, individual blocks may be deleted from the method 4000 without departing from the spirit and scope of the embodiments described herein.

At step 4002, the method 4000 detects, through the object detection module 200, the objects in the relevant geographical area and at step 4004, the method 4000 provides receive, through the first database 300, the object information relating to the geographical coordinates of the detected objects from the object detection module 200.

At step 4006, the method 4000 receive, via the second database 400, the identifier of the first database 300 containing the object information. The second database 400 is arranged to communicate with at least one of: the object detection module (200) and the first database 300 and at step 4008 the method 4000 receives, via at least one of: the object detection module 200, the first database 300 and the second database 400, a user request for the object information relating to the objects detected in the relevant geographical area, wherein the user request is received from the User Equipment 500.

FIG. 5 is an exemplary flowchart illustrating example steps for a method 5000 performed by the UE 500 for receiving information about the geographical area within the network 106.

The order in which the method 5000 is described is not intended to be construed as a limitation, and any number of the described method blocks may be combined in any order to implement the method 5000 or alternate methods. Additionally, individual blocks may be deleted from the method 5000 without departing from the spirit and scope of the embodiments described herein.

At step 5002, the method 5000 send, through the UE 500, the user request for the object information relating to objects detected in the relevant geographical area, wherein the user request is sent to at least one of: the object detection module 200, the first database 300 and the second database 400 arranged in the network 106.

At step 5004 the method 5000 receive, through the UE 500, at least one of: the request response containing the object information relating to the objects detected in the relevant geographical area from at least one of: the object detection module 200, and the first database 300 and the request response from the second database 400 containing the identifier of the first database 300 to obtain the object information from the first database 300.

The details of the method 4000 and the method 5000 are similar to details of the system 1000 and hence are not repeated for the sake of brevity. In an example, FIG. 6 shows a distribution of each of the object detection module 200, the first database 300, the second database 400 and the UE 500 in the system 1000.

The object detection module 200 may also referred to as a producer, for example, a camera. The first database 300 may also be referred as an Object Database, ODB. The second database 400 may also be referred as a Discovery Database, DDB, and the UE 500 may also be referred to as consumer, user or customer.

FIG. 6 shows one object detection modules 200, one ODB 300, one DDB 400 and one UE 500 however this is to be understood the system 1000 may comprise any number of object detection modules 200, the ODBs 300, the DDBs 400 and the UEs 500.

At step 602, the camera 200 reports the object to the ODB 300 detected by the camera 200. At step 604 the ODB stores the objects. All the objects are stored in at least one tile. In an example, the tile refers to a part of a larger bit-mapped image, herein an image of the detected object. At step 606, the car, UE 500, sends the user request to the ODB 300 for obtaining the object information. The car 500 shares the identifier of the car which comprise position (geographical area) of the car i.e., latitude and longitude information with the ODB 300. At step 608, the ODB translates the position of the object into the tile, collects the object on the tile and share the request response with the user of the car 500.

Again referring to FIG. 6, the ODBs 300 are integrated with a functionality to handle and to keep the ODBs 300 up to date. The functionality is provided to:

Translate the geographical coordinates (latitude/longitude) of the object to the tile. The translation is used to allocate the received detected object to a certain tile in the ODB 300 and is based on geographical coordinates obtained together with the object.

Read out the object information related to the tile in the ODB 300, based on the geographical coordinates received together with the user request for the object information.

Maintain the ODB 300 regarding object ageing or movement to remove the object from the tile or move the object to another tile based on object information about object speed and/or direction. The ODB 300 follows one or more rules or protocols for inserting the object information into the tile. The protocols to provide the objects to be inserted in the ODB 300, comprises proprietary protocols, based on publish-subscribe protocols, e.g., Message Queuing Telemetry Transport, MQTT.

Protocols to receive or respond to the user query for object information about the objects related to the tile. Such a protocol may be based on a publish-subscribe protocol e.g. MQTT. The user request may include actual coordinates where the UE 500 or requester is located so that the ODB 300 only reply with relevant objects relevant to the location of the UE 500. The data format of the objects in the tile may comprise ETSI CPM or SAE SDSM message.

The functionality is provided for communication with the central registry, i.e., the DDB 400. This protocol for example may be used to update the DDB 400 when a new ODB 300-A (shown later in FIG. 9) been started and may inform the DDB 400 about an address of the new ODB 300-A and the tiles handled by the new ODB 300-A.

In an example, when the consumer through the UE 500 connects direct to the producer(s) 200, the ODB 300 maintains the addresses for the producer(s) 200 as the identifier of the producer 200.

In beginning or at an initial stage, the ODB 300, is communicatively coupled to a few UEs 500 and a few producers 200, and thus the ODB 300 may handle multiple tiles, or larger tiles. But as usage grows the number of ODBs 300 increases which makes the tiles smaller as more tiles are stored in the ODB 300 and such smaller tiles may not be sufficient to provide an accurate object information to producers 200 or the consumers 500. Thus, the system 1000 provides the ODBs 300 to be distributed appropriately in a geographical area, to reduce the communication latency between the producers 200 and the consumers 500. With distribution of additional ODBs, the mobile network requires more internet access points to reduce the transport paths.

The system 1000 thus have the DDB 400. The system 1000 may also have a plurality of DDBs communicating with each other. Each DDB 400 may be communicatively coupled to a number of ODBs 300, producers 200 and the UEs 500. The DDB 400 is used to identify the selected ODB 300 from the plurality of ODBs 300 through the identifiers having the geographical area of the plurality of ODBs 300. The DDB 400 may then store the object information translated into the tile and the object information may then be fetched from the selected ODB 300 when requested by any of the producer 200, or the UE 500. The DDB 400 may be a more entity repository in the system 1000 since the DDB 400 contains static information about the objects, the ODBs 300 or the producers 200, that can be fetched by the users through the UE 500 and may be cached in the UE 500, and just refreshed at regular intervals to get information about potentially new ODBs 300 in the determined area or area of interest to the user.

The DDB may be associated with a well-known URL or the DDB may also be configured in the producer 200 or in the UE 500 of the consumers. The DDB would thus keep information about addresses (e.g. URLs or IP addresses) to ODBs and the tiles an ODB have information for, as well as information needed to establish a connection to an ODB. The DDB 400 may then be updated when the new ODB 300-A being deployed. This could be done automatically by using some registration procedure between the ODB 300 and the DDB 400, as illustrated in Error! Reference source not found.

In an example, FIG. 7 shows an arrangement or translation, also referred as representation of the object information i.e., the image of the object into the tile. All the objects in the 'world' may be organized in 'tiles', e.g., based on quadtree or geohash. To allocate a position to a geographical area, the tile based systems, here, provide different zoom levels to allow different tile sizes. In the proposed system 1000, the allocation of the position into the geographical area is over the tile performed through the ODBs 300.

As shown in FIG. 7, the zoom level of the object in the tile may be high, e.g., the zoom level 18 for quadtree may result in an area of around 175 * 175 meters, so according to the user request, the tile-based system arranged in the system 1000 may apply different zoom levels, for example zoom level 18 or higher over the objects. Different zoom levels of the object information (image) provide better perception of the object information. For example, in case the producers 200, like sensors such as cameras 200 are used to increase the perception of the object at an intersection, a zoom level 18 for quadtree may be sufficient for better perception of the object. As also discussed above, the ODBs 300 are used to store objects related to tiles. The ODBs 300 are likely distributed in a determined area for high performance and low latency, and distribution of the object information may depend on the performance needs, e.g. could be on state level, city level, or even more regional level.

FIG. 8a shows an example wherein the ODB 300 is handling the object information received from the producers 200. The consumer may then request the ODB 300 and obtain the object information stored in the database related to the tile.

As shown in FIG. 8a, at step 1, the producer 200 reports the object, at step 2, the ODB 300 stores the object information. At step 3, when the UE 500 request for the object according to the identifier/geographical area of the UE 500, the ODB 300 shares the object information after the translation of the object position into the tile, at step 4.

In an example as shown in FIG. 8b, as an alternative to use the ODB 300 for the objects, the camera 200, which is arranged locally in the relevant geographical area, reports the position of the camera and the object detected to the ODB 300 at step 1. At step 2, the ODB store and handle the object information. The system 1000 also provide the ODB 300 to store details of producers 200 i.e. the position/geographical area (identifiers). The identifier comprising the address information of the actual producers 200 of the objects that may be stored in the ODB 300 and the identifier may be shared with the UE 500 to connect directly with the producer.

As shown in step 3 and 4, the consumer may send the user request to the ODB 300. The consumer may share the consumer's identifier with the ODB to share details about an 'area of interest' for the consumer, i.e., the determined relevant geographical area. The consumer may receive the request response containing the identifier of the producers 200 for example, location of the camera, IP address of the camera etc. At step 5 and 6, the consumer may establish the end-to-end connection with the camera 200 and request for the information, e.g., data in digital format (raw video, Lidar data, Point cloud data) or object (translated over the tile) from the producer 200. The consumer 500 may establish end-to-end connections to multiple producers 200, to avoid use of old/obsolete data, to improve security and/or to exclude sources that might tamper with the data. According to step 6 of FIG. 8b, the system 1000 may also provide an additional option to provide raw data in digital format captured by the camera 200 to the consumer/user/UE 500. The raw data in the digital format to be used in case the consumer 500 is unsure about how trustworthy the producer's 200' algorithms are to detect the objects. In such scenario the consumer 500 may request for the raw data in digital format and analyse the raw data in digital format using its own algorithms by streaming the raw data in digital format to the UE 500. To support such feature, the object information provided by the ODB 300 or the DDB 400 is not limited to detected object information or address information to cameras 200 to obtain objects directly from the camera 200. The ODB 300 or the DDB 400 may also provide address information such as a URL or IP address and port information of the producer 200. The consumer 500 may use the URL or IP address and port information to request for the raw data in digital format. Then the consumer 500 may establish an end-to-end connection with the producer 200 and obtain the raw media/data in digital format.

In an example, the system 1000 may provide a security feature within the system 1000 to provide the sharing of the information of a geographical area through collaborative communication and approach. The system 1000 provide each of the producer 200, the first database 300, the second database 400 and the UE 500 to be accredited and approved to participate in the communication and sharing of the object information and the identifiers of each other. Mutual authentication is needed between the producer 200, the ODB 300, the DDB 400 and the UE 500. Also, secure and protected communication protocols need to be used between the producer 200, the ODB 300, the DDB 400 and the UE 500. The secure and protected communication protocols may be achieved by using a Public Key Infrastructure, PKI, solution where certificates to be used are provided to the producer 200, the ODB 300, the DDB400 and the UE 500. The certificates can then be used for identification and to secure the communication with e.g. Transport Layer Security, TLS, and Datagram Transport Layer Security, DTLS.

In an example, FIG. 9 provides an addition of the new ODB4 300-A into the network 106. At step 1, the new ODB4 registers by sharing the identifier (address) of the new ODB4 with the DDB 400 which has information about the plurality of ODBs (ODB1, ODB 2, ODB3 etc.). The ODB4 also shares the object information in terms of handled tiles to the DDB 400. At step 2, the DDB 400 stores the ODB4's identifier and the object information which is later shared according to the user request.

In an example, as shown in FIG. 10a, in step 1, the consumer 500 of the object information from the ODB 300 may download the identifier of the ODB 300 from the DDB 400. In step 2, the consumer 500 maintain locally information on where to fetch the object information based on its location i.e., the identifier of the consumer 500, e.g. in location latitude A and longitude B. for example, The consumer 500 is in tile xyz, the ODB 300 for tile xyz may be found on URL wz (or IP yz) as illustrated in Error! Reference source not found., (e.g., several ODB addresses can be received and cached by the consumer. Hence the consumer selects ODB to use). When consumer leaves the tiles supported by the current serving ODB, consumer 500 query the DDB to get a new ODB.

In an example, as shown in FIG. 10 b at step 1, the producer 200 of the object information may send the request or query the DDB 400 (just like the consumer 500 as discussed above) to obtain the identifier of the relevant ODB 300. For example, as shown in step 2, for a fixed camera, the camera (producer 200) obtains the identifier of ODB 300 that handles the tile where the camera 200 is mounted, and the object information needed to establish the connection to the ODB 300 toError! Reference source not found. 300. Alternatively, also a vehicle may act as a producer 200 of the object information for the ODBs 300.

In each of the FIG. 10a and 10b, instead of downloading the information from the DDB 400 and locally resolving the ODB 300, the DDB 400 may use the consumer500/producers 200 geographic location or the identifier as an input and respond with the relevant ODB 300 when requested by the user or the UE 500.
