Description

Technical Field

[0001] The present disclosure relates to the field of Bluetooth communications. Embodiments relate to a method for user equipment, a method for a communication device, an apparatus, a vehicle and a computer program. Background Art

[0002] Functionality that requires physical proximity between two Bluetooth Low Energy (BLE) communication participants may have a connection without physical proximity. The corresponding energy consumption depends on the BLE connection interval, which is the time when the next message exchange is scheduled. The shorter the connection interval, the higher the energy consumption. Therefore, improvements in BLE communication may be needed.

[0003] It is therefore found that BLE communication can be improved by adjusting the connection interval between the user equipment and the communication device. To this end, the user equipment obtains connection data to adjust the connection interval based on the connection data. Summary of the invention

[0004] The example provides a method for user equipment for adjusting a Bluetooth low energy connection interval with a communication device. The method includes obtaining connection data indicating a desired adjustment of the connection interval. In addition, the method includes adjusting the connection interval between the user equipment and the communication device based on the connection data. In this way, the connection interval of the BLE communication can be adjusted according to current needs. Therefore, energy consumption can be reduced. For example, if the distance between the user equipment and the communication device exceeds a certain distance, the connection interval can be increased (thereby reducing energy consumption).

[0005] In an example, the connection data may indicate a distance between the user equipment and the communication device, a location of the user equipment, a location of the communication device, interference with BLE communications between the user equipment and the communication device, and / or movement of the user equipment. In this way, the adjustment of the connection interval may be associated with different boundary conditions. For example, when the movement of the user equipment is determined, the connection interval may be reduced.

[0006] In an example, the method may further include determining a desired adjustment based on a distance between the user equipment and the communication device. In addition, the method may include obtaining distance data indicating a distance between the user equipment and the communication device, and comparing the distance data with a threshold, and if the threshold is exceeded or below, adjusting the connection interval. In this way, the connection interval may be adjusted to take into account the distance between the user equipment and the communication device. Thus, for example, if the user equipment is close to the communication device or near the communication device, the connection interval may be reduced, or if the user equipment is far from the communication device or moved away, the connection interval may be increased.

[0007] In an example, the connection interval may be increased or decreased based on the connection data. In this way, adjustment of the connection interval may be facilitated.

[0008] In an example, the method may further include obtaining usage data indicating the use of the adjusted connection interval, and resetting the connection interval based on the usage data. By obtaining the usage data, for example, the time of use and / or the location of use may be determined. The connection interval may be adjusted to a value different from a default value. For example, after a certain time, the connection interval may be reset to a default value. In this way, the adjustment of the connection interval may be associated with the current use.

[0009] In an example, the method may further include transmitting an adjustment signal to the communication device indicating the adjustment of the connection interval. In this way, the user equipment may notify the communication device (e.g., a vehicle including the communication device) of the adjusted connection interval. Therefore, the communication device may adjust the connection interval.

[0010] The example provides a method for adjusting a BLE connection interval with a user equipment for a communication device. The method includes receiving an adjustment signal indicating an adjustment of a connection interval from the user equipment, and adjusting a connection event interval between the user equipment and the communication device based on the adjustment signal. In this way, the adjustment of the connection interval can be notified to the communication device. Therefore, the communication device can perform certain measures to adjust the connection interval, for example, adjusting the connection interval of its BLE communication with the user equipment.

An example relates to a vehicle comprising an apparatus as described above.

[0012] The examples also relate to a computer program having a program code for executing the above method when the computer program is executed on a computer, a processor or a programmable hardware component. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] As used herein, the term "or" refers to a non-exclusive or, unless otherwise specified (e.g., "otherwise" or "or as an alternative"). In addition, unless otherwise specified, words used herein to describe relationships between elements should be broadly interpreted to include direct relationships or the presence of intervening elements. For example, when an element is referred to as being "connected" or "coupled" to other elements, the element may be directly connected or coupled to the other elements, or there may be intervening elements. Conversely, when an element is referred to as being "directly connected" or "directly coupled" to other elements, there are no intervening elements. Similarly, terms such as "between," "adjacent," and the like should also be interpreted in a similar manner.

[0019] The terms used herein are only used for the purpose of describing specific embodiments and are not intended to limit the exemplary embodiments. Unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" used herein are intended to also include plural forms. It should also be understood that the terms "comprise" or "include" when used herein specify the presence of stated features, integers, steps, operations, elements or components, but do not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components or groups thereof.

[0020] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the example embodiments belong. It should also be understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning consistent with their meaning in the context of the relevant art and will not be interpreted in an idealized or overly formal sense unless explicitly defined as such herein.

[0021] Figure 1 An example of a method 100 for user equipment is shown. Method 100 is used to adjust a BLE connection interval with a communication device. A (BLE) connection interval of a BLE communication may be an interval between two communication signals. A connection interval may be the time between two connection events, and within each connection event there may be a data packet transmission of the BLE communication. A reduction in the connection interval results in a shorter time between two connection events. Therefore, the connection latency may decrease as the connection interval decreases, or may increase as the connection interval increases. Therefore, there may be a trade-off between connection latency and energy consumption. Method 100 as described herein may be an industry standard, for example, part of a Bluetooth standard, or may be a best practice.

[0022] The method 100 includes obtaining 110 connection data indicating a desired adjustment of a connection interval. The connection data may be obtained 110 by, for example, determining by a processing circuit system of a user equipment and / or by, for example, receiving via an interface circuit system of the user equipment. For example, the user equipment may determine the distance between the user equipment and the communication device, for example, based on sensor data (such as a lidar sensor, a camera, an ultra-wideband sensor). In addition, the user equipment may determine the desired adjustment of the connection interval based on the distance. For example, the desired connection interval may increase as the distance between the user equipment and the communication device increases. For example, the user equipment may receive a connection interval signal indicating the desired connection interval from the communication device. In this way, the user equipment may adjust the connection interval according to a request of the communication device. For example, the user equipment may receive information about a current location (e.g., a garage of an owner of the user equipment). Therefore, the user equipment may determine the desired adjustment of the connection interval based on the current location.

[0023] Furthermore, the method 100 comprises adjusting 120 a connection interval between the user equipment and the communication device based on the connection data. The adjustment of the connection interval can be performed by adjusting the connection interval. By adjusting 120 the connection interval, the energy consumption and / or performance of the BLE connection can be adjusted. For example, by reducing the connection interval, the connection latency can be reduced, thereby improving the performance of the BLE connection. Alternatively, by increasing the connection interval, the energy consumption of the BLE connection can be reduced.

[0024] The technical problem of the trade-off between energy consumption and connection latency is described below in the context of a digital key according to the Car Connectivity Consortium (e.g., standard version 3 [1]). However, this is merely an illustrative example. The concept of adjusting the connection interval can also be applied to different areas of BLE communication, such as a user equipment for opening a door to provide certain functions of a smart home. For example, a communication device can trigger the lighting of a room in a smart home based on the location of the user equipment. If the user equipment is a certain distance away from the room, the connection interval between the communication device and the user equipment can be reduced to reduce energy consumption.

[0025] For the use of digital keys, the BLE connection interval should be as low as possible to increase the data exchange speed, especially when the user equipment is physically close to the communication device, for example, the communication device may be part of a vehicle. If the connection interval is large, then for example, the UWB ranging session setup handshake in other communications between the user equipment and the communication device will be slow. This problem is exacerbated when there is a lot of interference in the 2.4 GHz (BLE) band. In these cases, the user may not be able to open the vehicle, or the opening is delayed (functional degradation), which may reduce the user experience. On the other hand, device energy consumption depends on the connection interval. In some use cases, for example, when the user lives near the vehicle, the phone may always be connected to the vehicle. In this scenario, a 30 ms connection interval (as defined by the CCC in 19.5.9.2 Persistent RKE Actions of [3]) may not be necessary to ensure the functionality of vehicle access. Therefore, the problem is to decide when to reduce and increase the connection interval. This problem can be solved by obtaining 110 connection data and adjusting 120 the connection interval based on the connection data.

[0026] In an example, the connection data may indicate the distance between the user equipment and the communication device, the location of the user equipment, the location of the communication device, the interference of the BLE communication between the user equipment and the communication device, and / or the movement of the user equipment. For example, the connection data may be determined by the user equipment, for example, by a sensor (such as a motion sensor, a lidar sensor) of the user equipment. For example, the connection data may be received from another communication device part of the infrastructure of the communication device or the user's garage of a gas station or user equipment, for example. For example, the connection data may be determined by the user equipment, for example, based on the interference of the BLE communication between the ultra-wideband communication with the communication device and / or the user equipment and the communication device. If there is strong interference in the BLE communication between the user equipment and the communication device, the connection interval may be reduced to increase the transmission reliability, such as retransmission. In this way, if there is a high probability of needing to retransmit due to high interference, the connection data may indicate interference, thereby reducing the connection interval. For example, the interference of the BLE communication may be determined based on the retransmission of the BLE data packet. In principle, as the distance between the communication device and the user equipment increases, the connection interval may be increased. For example, the greater the distance between the user equipment and the communication device, the longer the connection interval may be.

[0027] The connection interval can be adjusted to any number of connection intervals (lengths). For example, there may be two different connection intervals: 30ms (for a distance of up to 20m, or up to 15m, up to 10m, or up to 5m) and 120ms (for a greater distance, for example, at least 20m, at least 25m, at least 30m). The adjustment condition may be determined based on the connection data, for example, reducing the connection interval from 120ms to 30ms. For example, a trigger may be defined to adjust the connection interval. The trigger may be a motion, a non-empty BLE data packet received from the communication device, or a lower limit of the minimum distance between the user equipment and the communication device. The connection data may indicate a trigger. Optionally, in order to ensure the functionality of vehicle access, the reduction of the connection interval should be performed immediately. The motion of the user equipment may be any movement of the user equipment. For example, the motion of the user equipment may depend on a motion threshold, for example, motion may only be detected when the user takes two, three, or four steps.

[0028] Optionally, several triggers may be combined. For example, if a movement of the user equipment is determined, a distance measurement of the user equipment may be initiated to determine the distance between the user equipment and the communication device. If the determined distance exceeds a threshold, the connection interval may be reduced. For example, if the user equipment transmits a ranging intention to the communication device, the connection interval may be reduced. In this way, if the user equipment may attempt to initialize a ranging session, for example, the reliability of the ranging session may be improved by reducing the connection interval.

[0029] Optionally or alternatively, the user equipment may determine proximity to the communication device. For example, the user equipment may perform a vehicle proximity check based on channel sounding and / or relative signal strength indication. If the proximity check indicates that the distance to the vehicle is below a threshold, the connection interval may be reduced.

[0030] Optionally or alternatively, the user equipment may determine the connection data based on user behavior. For example, if the user of the user equipment approaches the communication device several times in succession to unload the vehicle, the connection interval may be adjusted according to the user behavior, for example, the connection interval may be reduced and increased according to the user's approach. In this way, energy consumption may be reduced and the user experience may be kept unchanged. Alternatively, if the user is unloading the vehicle, he may return several times, and if there are several unlockings of the vehicle in a short period of time, the connection interval may be kept at 30ms.

[0031] Optionally or alternatively, the user equipment may determine the connection data based on location (e.g., GPS location). For example, geo-fencing and / or points of interest may be used to adjust the connection interval. For example, if the user stops at a gas station, a bakery, the likelihood of (re)entering the vehicle increases compared to if the user stops at the user's garage. Thus, for example, for the case of stopping at a gas station, the connection interval may be maintained at 30 ms.

[0032] Optionally or alternatively, the user equipment may determine connection data based on a history of functional usage. For example, if the user of the vehicle parks the vehicle in his or her own garage, the connection interval may be adjusted based on past use of the vehicle, e.g., the connection interval may be increased. Since human patterns are often repeated based on individual users (users of the user equipment), vehicle entry intent may be learned. This learned vehicle entry intent may be part of the connection data.

[0033] Optionally or alternatively, the user equipment may determine the connection data based on data from another sensor (e.g., an ultra-wideband sensor, a lidar sensor, a camera) that is unrelated to the BLE communication of the user equipment. For example, another sensor may be used to determine the distance between the user equipment and the communication device. In this way, the determination of the distance may be improved so that the connection interval may be adjusted more reliably. For example, if, for example, a UWB-based trajectory shows that the user is moving away from the vehicle, the user equipment may increase the connection interval (e.g., to 120ms).

[0034] In an example, method 100 may also include determining a desired adjustment based on a distance between the user equipment and the communication device. In addition, method 100 may include obtaining distance data indicating the distance between the user equipment and the communication device, comparing the distance data with a threshold, and adjusting the connection interval if it exceeds or falls below the threshold. In this way, adjustment of the connection interval may be facilitated. For example, the threshold may be the minimum distance between the communication device and the user equipment at which a 30ms connection interval may be used. If the user equipment is within the minimum distance, the connection interval may be adjusted to the standard 30ms connection interval defined in [1]. If the user equipment is not within the minimum distance, the connection interval may be increased. The comparison may be performed by a processing circuit system of the user equipment. The threshold may depend on the location of the communication device, the use of the communication device, or an undesirable user experience.

[0035] In an example, the connection interval may be increased or decreased based on the connection data. In this way, the connection interval may be adjusted to account for reduced energy consumption and / or reduced connection latency. For example, a user may provide input indicating desired performance of a BLE connection.

[0036] In an example, method 100 may also include obtaining usage data indicating the use of the adjusted connection interval, and resetting the connection interval based on the usage data. For example, the usage data may indicate the time of use, the location of use. In this way, resetting the connection interval may be facilitated. For example, the connection interval may be increased during parking in a garage.

[0037] In an example, the method 100 may further include transmitting an adjustment signal indicating the adjustment of the connection interval to the communication device. In this way, the user equipment may notify the communication device of the adjusted connection interval. Therefore, the communication device may similarly adjust the connection interval.

[0038] In general, user equipment may be a device capable of wireless communication. However, in particular, user equipment may be mobile user equipment, e.g., user equipment suitable for being carried around by a user. For example, user equipment may be a user terminal or user equipment within the meaning of a corresponding communication standard for mobile communication. For example, user equipment may be a mobile phone, such as a smartphone, or another type of mobile communication device, such as a smartwatch, a notebook computer, a tablet computer, or autonomous augmented reality glasses.

[0039] Generally speaking, the communication device may be a device capable of wireless communication. For example, the communication device may be part of a vehicle, for example, part of an electronic control unit of the vehicle.

[0040] Further details and aspects will be mentioned in conjunction with the embodiments described below. Figure 1 The examples shown in may include one or more optional additional features corresponding to one or more aspects mentioned in conjunction with the proposed concept or below (e.g., Figure 2-4 ) described in one or more examples.

[0041] Figure 2 An example of a method 200 for a communication device is shown. The method 200 is for adjusting a BLE connection interval with a user equipment. The method 200 includes receiving 210 an adjustment signal from the user equipment indicating an adjustment of the connection interval, and adjusting 220 a connection event interval between the user equipment and the communication device based on the adjustment signal. In this way, the communication device can be notified of the adjustment of the connection interval. Thus, the communication device can perform certain measures to adjust to the adjusted connection interval, for example, adjusting the connection interval of its BLE communication with the user equipment. The communication device can be a reference Figure 1 The counterpart of the user equipment described.

[0042] Further details and aspects will be mentioned in conjunction with the embodiments described above and / or below. Figure 2The examples shown in may include one or more optional additional features corresponding to one or more aspects mentioned in conjunction with the proposed concept or above (e.g., Figure 1 ) and / or the following (for example, Figure 3-4 ) described in one or more examples.

[0043] Figure 3 An example of adjusting the connection interval for active mode is shown. The active mode may be characterized by a short connection interval, for example, 30ms. Therefore, the active mode may achieve a good connection latency and / or user experience.

[0044] For example, after the movement 310 of the user equipment ends, a timeout (e.g., 2 minutes) can be used to define a time period in which the vehicle proximity check 320, 330 can be performed. The vehicle proximity check 320, 330 can be based on a relative signal strength indicator (of the BLE connection) as described above. Optionally or alternatively, channel detection can be used. If the vehicle proximity check 320, 330 indicates that the distance between the user equipment and the communication device is greater than a threshold, the connection interval can be adjusted. For example, the connection interval can be reduced so that an idle mode is set. Since the connection interval is reduced, the energy consumption of the BLE connection for the idle mode can be reduced.

[0045] Optionally or alternatively, adjusting the connection interval may be prohibited under certain conditions. For example, the user equipment may periodically scan the 2.4 GHz band for activity. If strong interference is present, the handshake to reduce the connection interval may be delayed due to retransmissions. Therefore, it may be beneficial to keep the connection interval at a predefined value (e.g., 30 ms). In addition, if the connection interval was previously increased, the interference may be used to predictively reduce the connection interval.

[0046] Optionally or alternatively, even without a trigger, the connection interval can be increased if the user equipment determines that the communication device is physically close. The determination of physical proximity can be based on a relative signal strength indicator. For example, BLE fingerprinting allows a threshold or more advanced algorithm to decide whether the user equipment is close to the vehicle. Optionally, the determination of physical proximity can be based on channel sounding (phase-based, e.g., mode 2). Via channel sounding, an approximate distance can be determined (with a measurement uncertainty of less than 1 m). A threshold value (e.g., 10 m) can be used as a proximity measurement for the communication device.

[0047] Furthermore, since it is possible to live close to a communication device (eg, less than 10 m away), it may be beneficial to use both the received signal strength indicator and channel sounding to increase the reliability of determining physical proximity.

[0048] As described above, if motion stops 310 and there is no active BLE communication (e.g., no non-empty BLE packets are received at the user equipment), the user equipment can check whether the user equipment is physically close to the communication device after a timeout (e.g., 2 minutes). If the user equipment is physically close to the communication device, the timeout can be reset and another vehicle proximity check can be performed after the timeout.

[0049] Further details and aspects will be mentioned in conjunction with the embodiments described above and / or below. Figure 3 The examples shown in may include one or more optional additional features corresponding to one or more aspects mentioned in conjunction with the proposed concept or above (e.g., Figure 1-2 ) and / or the following (for example, Figure 4 ) described in one or more examples.

For example, the proposed concept may be applied to public transportation (trains, buses) and future means of mobility (e.g., robotaxi).

[0052] like Figure 4As shown in , the corresponding interface circuit system 32 is coupled to the corresponding processing circuit system 34 at the device 30.
