METHOD FOR COMMUNICATION BETWEEN A BASE STATION AND AT LEAST ONE COMMUNICATIONS DEVICE, BASE STATION, COMMUNICATIONS DEVICE AND CORRESPONDING COMPUTER PROGRAM

Description

1. Field of the invention

[0001] The field of invention is that of telecommunications.

[0002] More specifically, the invention relates to uplink communications, i.e. from communication equipment to a base station, and downlink communications, i.e. from the base station to the communication equipment.

[0003] Here, communication equipment is understood to mean a network terminal equipment (also called UE for “User Equipment”), or an intermediate equipment of the network, such as a CPE (“Customer Premises Equipment”). Such communication equipment can therefore be mobile or fixed.

[0004] The proposed solution applies in particular, but not exclusively, in the context of LTE / 4G (“Long Term Evolution”) or 5G NR (“New Radio”) mobile networks. 2. Prior art

[0005] Traditionally, we distinguish three main configurations of quality of service or QoS (“Quality of Service”) depending on access to radio spectral resources between communication equipment: configuration associated with a classic radio resource allocation, called BE or "best effort". Classic allocation corresponds to a radio QoS configuration with a radio quality level that can be low if the cell load is high. In this configuration, nothing is set up specifically for a given device. The base station applies a scheduling algorithm that distributes resources to the different devices in the cell it serves, following fairness rules. Such algorithms are, for example, of the "Round Robin" or "Proportional fair" type; configuration associated with a radio resource allocation with relative prioritization. Allocation with relative prioritization corresponds to the radio QoS configuration with an intermediate radio quality level if the cell load is high.According to this configuration, the base station authorizes more resources to flows of a device with relative prioritization (with "privileged QoS") than to those called "best effort"; configuration associated with an allocation of radio resources with strict prioritization at guaranteed bit rate called "GBR" ("Guaranteed bit rate"). The allocation with strict GBR prioritization corresponds to a radio QoS configuration presenting a high level of radio quality even if the cell load is high. The base station ensures a minimum throughput in the upstream and / or downstream direction to one or more flows of the device. The prioritization between the BE flows and the GBR flows is therefore strict. It should be noted that if the total resources of the cell allow it, the observed throughputs of the equipment with guaranteed throughputs can be higher than these minimum throughputs.

[0006] These three configurations, presenting different QoS levels, can coexist at the same time on different flows of the same device.

[0007] Hereinafter, a BE flow (respectively a “privileged QoS” flow, respectively a “GBR” flow) is a flow transmitted or received by a communication device with a radio quality of service configuration associated with a “BE” allocation (respectively with relative prioritization, respectively with strict prioritization at guaranteed throughput).

[0008] Typically, the mobile network (particularly the base station) is configured to provide a guaranteed target throughput as a priority to the flows of devices benefiting from a GBR configuration. The remaining radio resources are then allocated, unless there is a specific configuration such as throughput limitation, to all devices, including devices with at least one "GBR" flow.

[0009] GBR speeds correspond to the necessary, useful speeds to ensure the corresponding service. This could be, for example, the bandwidth required to transmit HD video streams, 3D, etc. However, there are some disadvantages to setting up a configuration associated with an allocation with strict prioritization at guaranteed speed for certain equipment, particularly mobile terminals.

[0010] Indeed, when a terminal receiving or transmitting at least one GBR stream is far from the base station, for example located at the edge of the cell, or when the transmission channel between the base station and the terminal has a lot of interference, the amount of resources allocated to this terminal to offer it a guaranteed throughput is very high, and is to the detriment of the other terminals in the cell receiving or transmitting at least one “non-GBR” stream (for example the terminals receiving or transmitting at least one BE stream or with relative prioritization). In other words, a terminal receiving or transmitting at least one GBR stream can drastically reduce the capacity of the cell and thus deteriorate the performance of the other terminals.

[0011] Furthermore, the aggregation of terminals receiving or transmitting at least one GBR flow in the same cell can create a shortage of resources for terminals receiving or transmitting at least one "non-GBR" flow. In extreme conditions of cellular overload, the resources may even become insufficient to honor the sum of the GBR rates of the terminals in the cell.

[0012] We can thus define four typical states of a radio cell served by a base station: "Congestion-free" cell: there are more radio resources than necessary to handle the traffic of the communication equipment in the cell. The expected throughputs on the GBR flows are reached or even exceeded, the traffic of the BE flows is handled without encountering any radio limitation; overall congestion controlled in the cell: the communication equipment generates traffic mobilizing all the radio resources of the cell. The volume of radio resources required to serve the GBR flows is less than the capacity of the cell, and corresponds to the operator's planning. QoS mechanisms will make it possible to serve the "GBR" flows. The BE flows share the remaining radio resources, as defined by the operator; overall congestion not controlled in the cell: the communication equipment generates traffic mobilizing all the radio resources of the cell.The volume of radio resources required to serve GBR flows is less than the cell capacity, but greater than the operator's planning. QoS mechanisms will allow "GBR" flows to be served. BE flows share the remaining uncontrolled volume of radio resources, which can drastically decrease and negatively impact the quality of experience of users of equipment transmitting or receiving these BE flows; uncontrolled GBR congestion in the cell: all communication equipment generates traffic mobilizing all the radio resources of the cell. In this case, the theoretical volume of radio resources required to serve GBR flows is greater than the cell capacity, there is a shortage. QoS mechanisms will no longer allow all GBR flows to be served as desired. The network can then trigger protection mechanisms.However, despite the implementation of protection mechanisms, the quality of experience for users of equipment receiving or transmitting "non-GBR" streams is extremely degraded. In addition, the guaranteed GBR target bitrates cannot all be met, and customer service (e.g. HD video, 3D, etc.) may be disrupted.

[0013] To avoid uncontrolled GBR congestion in the cell, an operator can implement mechanisms limiting the volume of radio resources usable for GBR configurations (e.g., "slice"). When the theoretical volume of radio resources required to serve GBR flows reaches this authorized "GBR" resource threshold, there is a shortage. One advantage of these mechanisms is that BE flows can be served by the radio resources preserved thanks to this mechanism.

[0014] In the last two cases of uncontrolled congestion, the proposed solutions do not allow the quality of service to be maintained equitably for all the equipment in a cell served by a base station.

[0015] There is therefore a need for a new technique for allocating radio resources to communication equipment attached to a base station. WO 2020 / 125525 concerns the allocation of resources in the downlink channel, for a single terminal, and more precisely the selection of an allocation type (type 0, type 1). 3. Statement of the invention

[0016] The invention proposes a solution which does not have all the drawbacks of the prior art, in the form of a method of communication between a base station and at least one piece of communication equipment attached to the base station, said at least one piece of communication equipment comprising client equipment.

[0017] According to the invention, such a method comprises: obtaining at least one first quality value of an uplink or downlink radio link between the base station and the client equipment, allocating radio resources to said at least one equipment attached to the base station (i.e. to the client equipment attached to the base station and, where appropriate, to at least one other equipment attached to the base station) according to an allocation scheme implementing a first radio QoS configuration dependent on said at least one first uplink or downlink value for at least one stream transmitted or received by the client equipment, if at least one current quality value of the uplink or downlink radio link between the base station and the client equipment, obtained from at least one measurement carried out by the client equipment or the base station, is associated with a radio link quality level lower than said at least one first uplink or downlink value respectively,allocation of radio resources to said at least one device attached to the base station according to an allocation scheme implementing a second radio QoS configuration for at least one stream transmitted or received by the client device, said second configuration having a radio quality of service level lower than said first configuration.

[0018] Thus, according to the invention, for example during a first phase, a first quality value of the radio link between the base station and the client equipment in the uplink direction and / or a first quality value of the radio link between the base station and the client equipment in the downlink direction is obtained.

[0019] This first value of the quality of the radio link in the upstream and / or downstream direction can be associated with the first QoS configuration.

[0020] The base station can thus allocate radio resources to the client equipment and possibly to the other equipment that it serves according to an allocation scheme implementing this first radio QoS configuration (for example of the allocation type with strict prioritization at guaranteed throughput), for at least one flow transmitted or received by the client equipment.

[0021] If the quality of the radio link between the base station and the client equipment in the uplink and / or downlink direction deteriorates, the base station can modify the allocation scheme to allocate radio resources by implementing a second radio QoS configuration for at least one flow transmitted or received by the client equipment (for example of the allocation type with relative prioritization or “best effort”), for example during a second phase implementing at least one iteration.

[0022] In this way, the maintenance of the QoS rules applied to at least one flow of the client equipment is conditioned on the observed quality of the radio link between the base station and the client equipment. If the quality of the radio link degrades (either in the uplink direction, or in the downlink direction, or in both directions, depending on the embodiment), the base station replaces for example the initial configuration of the QoS mechanisms (first radio QoS configuration) with a less favorable configuration for the client equipment (second radio QoS configuration).

[0023] In other words, the proposed solution makes it possible to activate QoS differentiation mechanisms for a client device by controlling the quantity of radio resources consumed by this access. For example, if the radio link is of good quality (as during the first phase), the quantity of radio resources to maintain a guaranteed throughput is reasonable, and the base station can activate a first configuration associated with an allocation with strict prioritization at guaranteed throughput for at least one flow of the client device. On the other hand, if the radio link is of poorer quality, the quantity of radio resources to maintain a guaranteed throughput is very high, and the base station can activate a second configuration associated with an allocation with relative or BE-type prioritization for at least one flow of the client device.It should be noted that the reasons for the degradation can be multiple: degradation of the antenna of the customer equipment, its support, appearance of an obstacle (construction of a wall, building, growth of a tree, etc.), weather conditions, etc.

[0024] This makes it possible to help control the disturbances caused to other equipment attached to the base station compared to a schedule established by the operator (initially for example).

[0025] For example, the first and second radio quality of service configurations belong to the group comprising: a configuration associated with a classic “best effort” type radio resource allocation (for the second configuration only); a configuration associated with a radio resource allocation with relative prioritization; a configuration associated with a radio resource allocation with strict prioritization with guaranteed throughput.

[0026] In all cases, the second radio QoS configuration has a lower quality level than the first configuration. For example, the first configuration is of the configuration type associated with an allocation with strict prioritization with guaranteed throughput, and the second configuration is of the configuration type associated with an allocation with relative prioritization or of the BE type.

[0027] According to a particular embodiment, the method implements, prior to the allocation of radio resources according to an allocation scheme implementing a second radio quality of service configuration, the reception of said at least one current value in the downlink direction, from the client equipment.

[0028] The client equipment can thus carry out one or more measurements of the quality of the downlink radio link, at different times, to obtain one or more values of the quality of the downlink radio link, and send the current value(s) back to the base station, or an average of these current values. It is thus possible, for example, to have information on the quality of the radio link in real time.

[0029] According to another embodiment, the method implements, prior to the allocation of radio resources according to an allocation scheme implementing a second radio quality of service configuration, the reception of a notification from the client equipment, informing the base station that said at least one current downlink value is associated with a radio link quality level lower than said at least one first downlink value.

[0030] The client equipment can thus carry out one or more measurements of the quality of the downlink radio link, at different times, to obtain one or more downlink radio link quality values, and compare the current downlink value(s) with the first downlink value. If at least one current value has a radio quality level lower than the first value, a notification can be transmitted to the base station.

[0031] According to these different embodiments, the base station can thus know in “real time” the current value of the quality of the radio link for the client equipment (or any other equipment transmitting this information to the base station), or more simply receive a notification when the current value changes sufficiently to be taken into account.

[0032] According to a particular embodiment, the allocation of radio resources according to an allocation scheme implementing a second radio quality of service configuration is implemented when several successive current values in the uplink or downlink direction are associated with a radio link quality level lower than said at least one first uplink or downlink value respectively.

[0033] Thus, in some embodiments, the base station may not modify the allocation of resources for the client equipment, to switch from a first configuration to a second configuration, in the event of occasional degradation of the radio link. For example, a time range may be defined by the operator of the order of a few seconds, a few minutes or a few hours. If more than half of the current values measured over this time range have a radio link quality level lower than the first value, the base station may modify the allocation of resources for at least one stream of the client equipment to switch from a first configuration to a second configuration.

[0034] Similarly, a notification as described above can be transmitted to the base station only if more than half of the current values measured over a defined time range have a radio link quality level lower than the first value.

[0035] According to a particular embodiment, the method further implements: if at least one new current quality value of the uplink or downlink radio link between said base station and said client equipment, obtained from at least one new measurement carried out by said client equipment or said base station, is associated with a radio link quality level greater than or equal to at least one second quality value of a radio link between the base station and the client equipment, uplink or downlink respectively, allocation of radio resources to said at least one equipment attached to said base station according to an allocation scheme implementing said first radio quality of service configuration for at least one stream transmitted or received by said client equipment.

[0036] According to this embodiment, the base station can again modify the allocation of radio resources to return to the first configuration for at least one stream of the client equipment, when the quality of the radio link in the upstream and / or downstream direction, one or the other, is no longer degraded for example, or is less degraded.

[0037] For example, said at least one first and / or second value or current value in ascending or descending direction belongs to the group comprising: a received power of a reference signal (or RSRP, in English "Reference Signal Receive Power"); a channel quality indicator (or CQI, in English "Channel Quality Indicator"); an indicator constructed from the CQI; a channel state indicator (or CSI, in English "Channel State Information"); an indicator constructed from the CSI, for example a CRI-RI-PMI-CQI indicator (with RI a rank indicator "Rank Indicator" and PMI a precoding matrix indicator "Precoding Matrix Indicator"); etc.

[0038] RSRP is an average value of the received power of the reference signal emitted by the base station. It is a simple measurement, carried out by the physical layer of the communication equipment, which is expressed in Watts or dBm. The value is typically between -140 dBm (poor quality radio link) and -44 dBm (very good quality radio link).

[0039] RSRP therefore makes it possible to measure a first and / or second value and / or current value of the quality of the downlink radio link at a time or over a time range. RSRP can also be used to estimate the quality of the uplink radio link.

[0040] The CQI is an indicator of the quality of the radio link, determined by the communication equipment. It can be used by the base station, in particular by the scheduler, to determine the modulation to be used at a given time.

[0041] The CQI therefore makes it possible to measure a first and / or second value and / or current value of the quality of the downlink radio link at an instant or over a time range.

[0042] The CSI, or CRI-RI-PMI-CQI, can be used in particular to estimate the quality of the upstream radio link.

[0043] Other indicators can also be used to obtain a first and / or second value and / or current value, in ascending and / or descending direction.

[0044] According to a particular embodiment, the second value in the upstream and / or downstream directions is equal to the first value in the upstream and / or downstream directions.

[0045] Alternatively, the second up and / or down value is different from the first up and / or down value.

[0046] In particular, said allocation of radio resources according to an allocation scheme implementing said first radio quality of service configuration for at least one stream transmitted or received by said client equipment is implemented if said at least one new current uplink radio link quality value is greater than said at least one second uplink value and if said at least one new current downlink radio link quality value is greater than said at least one second downlink value.

[0047] In other words, in some embodiments, the base station may again modify the allocation of radio resources to return to the first configuration for at least one stream of the client equipment, when the quality of the upstream and downstream radio link is no longer degraded, or is less degraded.

[0048] According to a particular embodiment, the allocation of radio resources according to an allocation scheme implementing a second radio quality of service configuration implements said first radio quality of service configuration for at least one stream transmitted or received by equipment attached to said base station, distinct from said client equipment.

[0049] In other words, in some embodiments, the transition from a first configuration to a second radio quality of service configuration concerns only the client equipment, for which the quality of the radio link is degraded. The configuration of the other equipment(s) attached to the base station can be done independently of the change of configuration for the client equipment.

[0050] The allocation scheme can thus allocate radio resources according to the second quality of service configuration for the client equipment, and according to the first quality of service configuration for at least one other equipment attached to the base station.

[0051] According to a particular embodiment, said at least one first quality value of an uplink or downlink radio link between the base station and the client equipment, and / or said at least one second quality value of an uplink or downlink radio link between the base station and the client equipment, is obtained from: of at least one measurement carried out by said client equipment; of at least one measurement carried out by said base station; of a reading in a table, an abacus, etc.

[0052] Thus, according to a first example, the client equipment performs one or more measurements of the quality of the downlink radio link, at different times, and sends this or these measurements back to the base station, or an average of these measurements. The first / second downlink value can be obtained from this or these measurements, or from the average of these measurements.

[0053] In a second example, the base station performs one or more upstream radio link quality measurements at different times. The first / second upstream value can be obtained from this measurement or from the average of these measurements.

[0054] In particular, the first / second uplink and / or downlink value may be determined when the equipment is stable, in the geographical sense (its position is substantially fixed) and / or radio sense (its transmission channel varies little). For example, the equipment is a mobile terminal which remains within a radius of 25 meters around an initial position) for a certain time (for example for at least 3 to 5 minutes). In this case, the terminal is equipped with geolocation means, making it possible to determine that its position is substantially fixed.

[0055] According to a third example, the first / second value in ascending and / or descending direction is a theoretical value, obtained from tables such as tables, abacuses, etc.

[0056] According to a fourth example, the first / second uplink and / or downlink value corresponds to an acceptability threshold for the quality of the radio link defined by the operator.

[0057] In a particular embodiment, the method comprises, for example during the first phase, preliminary steps of obtaining at least one reference value for the quality of an uplink or downlink radio link between the base station and the client equipment, and of verifying that said at least one first uplink or downlink value is associated with a radio link quality level greater than or equal to said at least one uplink or downlink reference value respectively.

[0058] In this case, the first value in the upstream or downstream direction can, for example, be measured when the equipment is installed and compared with a reference value in the upstream or downstream direction, obtained from a table, abacus, etc.

[0059] These steps can help validate that the first “practical” value in the uplink and / or downlink direction is associated with a radio link quality level greater than or equal to the “theoretical” reference value in the uplink and / or downlink direction.

[0060] Another embodiment relates to a corresponding base station, configured to communicate with at least one communication equipment, said at least one communication equipment comprising a client equipment, comprising: means for obtaining at least a first quality value of an uplink or downlink radio link between said base station and said client equipment, means for allocating radio resources to said at least one equipment attached to said base station according to an allocation scheme implementing a first radio quality of service configuration dependent on said at least one first uplink or downlink value for at least one stream transmitted or received by said client equipment, means for allocating radio resources to said at least one equipment attached to said base station according to an allocation scheme implementing a second radio quality of service configuration for at least one stream transmitted or received by said client equipment, activated if at least one current quality value of the uplink or downlink radio link between said base station and said client equipment,obtained from at least one measurement carried out by said client equipment or said base station, is associated with a radio link quality level lower than said at least one first upstream or downstream value respectively, said second configuration having a radio service quality level lower than said first configuration.

[0061] Such a base station is particularly suitable for implementing the communication method described above. It is, for example, an eNodeB or gNode. Such a base station may of course include the various characteristics relating to the method according to the invention, which may be combined or taken in isolation. Thus, the characteristics and advantages of the base station are the same as those of the method described above. Consequently, they are not detailed further.

[0062] The invention also relates to a method for managing communication between a base station and at least one communication device attached to the base station, said at least one communication device comprising a client device, comprising, implemented by said client device: obtaining at least one first quality value of a downlink radio link between the base station and the client equipment, if said at least one first downlink value is measured by the client equipment, transmitting said at least one first downlink value to the base station, intended to be used by the base station for allocating radio resources to said at least one equipment attached to the base station according to an allocation scheme implementing a first radio quality of service configuration dependent on said at least one first downlink value for at least one stream transmitted or received by the client equipment, measuring at least one current quality value of the downlink radio link between the base station and the client equipment, transmitting said at least one current downlink value to the base station,or a notification informing the base station that said at least one current downlink value is associated with a radio link quality level lower than said at least one first downlink value, said at least one current downlink value or said notification being intended to be used by the base station for the allocation of radio resources to said at least one equipment attached to the base station according to an allocation scheme implementing a second radio quality of service configuration for at least one stream transmitted or received by the client equipment, said second configuration having a radio quality of service level lower than said first configuration.

[0063] According to the invention, the client equipment can thus inform the base station in real time if the quality of the radio link between the base station and the client equipment deteriorates. Part of the processing ("monitoring") is thus moved from the base station to the client equipment. In this way, the base station can modify the allocation scheme to allocate radio resources according to a second radio QoS configuration for at least one stream transmitted or received by the client equipment (for example of the allocation type with relative prioritization or "best effort").

[0064] It is noted that if said at least one first downlink value is previously known to the base station (for example obtained from a table, such as a reference table), there is no point in transmitting it from the client equipment to the base station.

[0065] In particular, the client equipment can implement a step of determining its geographical position. Its geographical position can in particular be determined for each measurement of at least one current value. Information representative of this position can be sent back to the base station.

[0066] It is thus possible to determine whether the position of the client equipment is substantially fixed.

[0067] The invention also relates to a corresponding client equipment, configured to communicate with a base station, comprising: means for obtaining at least one first quality value of a downlink radio link between said base station and said client equipment, means for transmitting said at least one first downlink value to said base station, intended to be used by said base station for allocating radio resources to at least one equipment attached to said base station according to an allocation scheme implementing a first radio quality of service configuration dependent on said at least one first downlink value for at least one stream transmitted or received by said client equipment, activated if said at least one first value is measured by the client equipment, said at least one equipment attached to said base station comprising said client equipment, means for measuring at least one current quality value of the downlink radio link between said base station and said client equipment,means for transmitting said at least one current downlink value to said base station, or a notification informing said base station that said at least one current downlink value is associated with a radio link quality level lower than said at least one first downlink value, said at least one current downlink value or said notification being intended to be used by said base station for the allocation of radio resources to said at least one equipment attached to said base station according to an allocation scheme implementing a second radio quality of service configuration for at least one stream transmitted or received by said client equipment, said second configuration having a radio quality of service level lower than said first configuration.

[0068] Such equipment is particularly suitable for implementing the communication management method described above. For example, such equipment is mobile network equipment (mobile phone, smartphone, laptop, etc., particularly capable of communicating on an LTE or NG network) or fixed intermediate equipment installed at a customer's site (individual, company, etc.) and which is connected to the infrastructure of an operator / service provider (CPE).

[0069] According to a particular embodiment, such equipment is equipped with geolocation means, for example a GPS.

[0070] The client equipment may of course include the various characteristics relating to the method according to the invention, which may be combined or taken in isolation. Thus, the characteristics and advantages of the client equipment are the same as those of the method described above. Consequently, they are not detailed further.

[0071] The invention also relates to one or more computer programs comprising instructions for implementing a communication method or a communication management method as described above when this or these programs are executed by at least one processor.

[0072] The invention further relates to one or more computer-readable recording media, on which one or more computer programs are recorded, comprising program code instructions for executing at least one step of a communication method or a communication management method as described above, according to any of the embodiments. Such recording media may be any entity or device capable of storing a program. 4. List of figures

Description of a particular embodiment 5.1 General principle

[0074] We are in the context of a communication network implementing a base station (for example eNodeB, gNode, etc.) and at least one communication device (for example a terminal, a CPE, etc.) located in the cell served by the base station, said at least one communication device comprising a client device.

[0075] The general principle of the invention is based on a change in the radio quality of service configuration applied to at least one stream of a communication device, to move from a first configuration to a second configuration presenting a lower radio quality of service level, when the quality of the radio link between the base station and the communication device deteriorates.

[0076] For example, the first configuration can be associated with an allocation with strict prioritization with a first guaranteed flow rate (for example negotiated in advance with the operator) and the second configuration can be associated with an allocation with strict prioritization with a second guaranteed flow rate, lower than the first guaranteed flow rate.

[0077] In another example, the first configuration may be associated with an allocation with strict prioritization with guaranteed throughput and the second configuration may be associated with an allocation with relative prioritization.

[0078] In yet another example, the first configuration may be associated with a strict prioritization allocation with guaranteed throughput and the second configuration may be associated with a best effort allocation.

[0079] In a final example, the first configuration can be associated with an allocation with relative prioritization and the second configuration can be associated with a “best effort” allocation.

[0080] The proposed solution can thus, in at least certain embodiments, help to improve the quality of service for the equipment(s) located in the cell served by the base station compared to at least certain solutions of the prior art, in particular in the two cases of uncontrolled congestion presented in relation to the prior art.

[0081] In particular, the invention proposes a new solution for the allocation of radio resources to the communication equipment attached to the base station, making it possible, according to a particular embodiment, to optimize the quality of service for all the equipment located in the cell served by the base station.

[0082] Below is presented, in relation to the figure 1 , the main steps implemented by the base station according to certain embodiments of the invention.

[0083] During a first phase 11, called the initialization phase, a first quality value of a radio link between the base station and a client equipment attached to the base station in the uplink direction and / or a first quality value of the radio link between the base station and the client equipment in the downlink direction can be obtained (111). Such first uplink and / or downlink values can be obtained from at least one measurement of the quality of the radio link carried out by the client equipment, from at least one measurement of the quality of the radio link carried out by the base station, from a reading in a table, etc.

[0084] The base station (or the “scheduler”) can allocate (112) radio resources to the client equipment, and, where appropriate, to at least one other equipment attached to the base station, according to an allocation scheme implementing for example, for at least one stream transmitted or received by the client equipment, a first radio quality of service configuration dependent on the first upstream and / or downstream value(s) (for example by using a dedicated GBR “bearer”).

[0085] For example, if the first radio link quality value is of the order of -70dBm, which means that the radio link is of good quality, the first radio quality of service configuration can be associated with an allocation with strict prioritization at guaranteed throughput, with a high throughput, for example of the order of a few tens of megabits per second. If the first radio link quality value is of the order of -95dBm, which means that the radio link is of average quality, the first radio quality of service configuration can be associated with an allocation with strict prioritization at guaranteed throughput with an average throughput, for example of the order of a few megabits per second, or with an allocation with relative prioritization.

[0086] During a second phase 12, called the operating phase, several uplink and / or downlink radio link quality values, called current uplink and / or downlink values, can be measured at different times. The current uplink values can be obtained from at least one radio link quality measurement carried out by the base station (121), and the current downlink values can be obtained from at least one radio link quality measurement carried out by the client equipment. Optionally, the client equipment can transmit the current measurements / values to the base station.

[0087] Optionally, an average current value in the downlink and / or uplink direction may be determined for a given time range, by the base station and / or by the client equipment. The current value(s) (possibly averaged) in the downlink and / or uplink direction may be compared to the first value in the downlink and / or uplink direction respectively. This comparison may be performed by the base station or by the client equipment, depending on the information available to the base station or the client equipment. If the comparison is performed by the client equipment, the client equipment may send a notification to the base station to inform it of the result of the comparison (current value in the downlink and / or uplink direction associated with a quality level lower than the first value in the downlink and / or uplink direction, or significant change in the current value in the downlink and / or uplink direction, etc.).

[0088] If the quality of the radio link between the base station and the client equipment deteriorates, i.e. if: a current value in the downlink and / or uplink direction, or an average current value in the downlink and / or uplink direction over a given time range, or at least one current value in the downlink and / or uplink direction over a given time range, is associated with a quality level lower than the first value in the downlink and / or uplink direction respectively, the base station (or the "scheduler") can allocate (122) radio resources to the client equipment and, where appropriate, to at least one other equipment attached to the base station, according to an allocation scheme implementing, for at least one stream transmitted or received by the client equipment, a second radio quality of service configuration having a radio quality of service level lower than the first configuration (for example by using a dedicated non-GBR "bearer").

[0089] According to a particular embodiment, it is also possible to remain at the first radio quality of service configuration for at least one stream transmitted or received by the client equipment if the quality of the radio link between the base station and the client equipment remains stable, or to return to the first radio quality of service configuration for at least one stream transmitted or received by the client equipment if the quality of the radio link between the base station and the client equipment improves, i.e. if: a new current value in descending and / or ascending direction, or a new average current value in descending and / or ascending direction over a given time range, or at least one new current value in descending and / or ascending direction over a given time range, is associated with a radio link quality level greater than or equal to a second quality value of a radio link between the base station and the client equipment, downlink and / or uplink direction respectively.

[0090] The operating phase may implement at least one iteration of the steps described above. Thus, new measurements of the quality of the uplink and / or downlink radio link between the base station and the client equipment may be carried out regularly, for example every second, every 30 seconds, every minute, or when a change in the channel is detected. Information on the quality of the radio link may thus be available in “real time”. The allocation of radio resources of the various equipment attached to the base station may be updated taking into account the evolution of the quality of the uplink and / or downlink radio link between the base station and the client equipment. 5.2 Implementation example

[0091] An example of implementation of the invention is described below, in a network comprising a base station and a plurality of communication devices.

[0092] The following describes the use of the quality of the radio link between the base station and at least one piece of communication equipment, called client equipment, in the downstream direction, to optimize the allocation of resources. Of course, this is a simple example, and the quality of the radio link in the upstream direction can also be used, alone or in combination with the quality of the radio link in the downstream direction, to optimize the allocation of resources.

[0093] According to the example illustrated in figure 2 , we consider a base station 21, a first communication device installed on a first customer site, for example a business or residential CPE1 22 allowing FWA access (“Fixed Wireless Access”), a second communication device installed on a second customer site, for example a business or residential CPE2 23 also allowing FWA access, and a plurality of terminals 24. The base station communicates with the core network 20.

[0094] When installing the CPE1 22, the CPE1 22 can measure a first quality value of a downlink radio link between the base station and the CPE1 22, for example by measuring the reception power of a reference signal.

[0095] This first value, noted RSRP1, can in particular be transmitted to the base station, or to the operator, to verify that it is indeed associated with a quality level greater than or equal to a value (reference for example) known to the base station, or to the operator. For example, such a value is defined from tables such as reference tables or abacuses.

[0096] Alternatively, a radio link quality acceptability threshold may be defined, and the base station, or the operator, may verify that the first value is indeed associated with a quality level greater than or equal to the acceptability threshold. Such an acceptability threshold may in particular be defined from a compromise between the estimated load in the cell and the desired guaranteed throughput.

[0097] Thus, according to at least one embodiment, the operator can determine in advance a guaranteed flow rate, a number of users / or GBR flows per cell, a radio link quality acceptability threshold (from which a user or a flow can obtain a guaranteed GBR flow rate).

[0098] According to the example illustrated in figure 2 , this RSRP1 value is for example of the order of -80dBm.

[0099] The base station / operator then indicates whether the first customer site's access is eligible, and whether the desired guaranteed speeds are allowed. Otherwise, the operator may offer lower guaranteed speeds or non-guaranteed speeds.

[0100] It is assumed below that the desired guaranteed throughputs are permitted. The base station can therefore allocate resources to the various devices in its cell. In particular, it can implement a radio quality of service configuration associated with an allocation with GBR prioritization for at least one flow entering or leaving the CPE1 22 of the first customer site, and a “best effort” allocation for at least one other flow entering or leaving the CPE1 22 of the first customer site.

[0101] Similarly, the base station may implement a radio quality of service configuration associated with an allocation with GBR prioritization for at least one flow entering or leaving the CPE2 23 of the second customer site, and a “best effort” allocation for at least one other flow entering or leaving the CPE2 23 of the second customer site.

[0102] The cell is therefore in a situation of no congestion or controlled global congestion type.

[0103] The CPE1 22 measures at different times the quality of its radio link with the base station 21, for example by measuring the reception power of a reference signal.

[0104] If the current RSRPc value is associated with a radio quality level lower than the first RSRP1 value, there is over-consumption of radio resources and fewer resources available (for example fewer RB "resource blocks") for other equipment in the cell.

[0105] If the current RSRPc value is associated with a radio quality level greater than or equal to the first RSRP1 value, there is underconsumption of radio resources and more resources available (for example more RB "resource blocks") for other equipment in the cell.

[0106] According to a first example illustrated in figures 3A et 3B , we consider that at least one current RSRPc value measured by the CPE1 22 of the first customer site decreases (for example, going from -80dBm to -105dBm), for example following the presence of an obstacle on the transmission channel.

[0107] The cell then enters a situation of uncontrolled global congestion.

[0108] In the example illustrated in figure 3A , without implementing the invention, the base station 21 allocates resources to the different equipment (CPE1 22, CPE2 23, terminals 24) and seeks to provide a guaranteed target rate as a priority to the flows of the equipment benefiting from a GBR configuration (CPE1 22 and CPE2 23). The remaining radio resources are then allocated to the other equipment (terminals 24) and to the BE flows of the CPE1 22 and CPE2 23.

[0109] There is overconsumption of radio resources to provide CPE1 22 with the desired guaranteed throughput. As the base station seeks to prioritize resources for GBR streams from CPE1 22 and CPE2 23, there are few radio resources left to allocate to BE streams from CPE1 22, CPE2 23 and terminals 24.

[0110] Each BE flow is therefore negatively impacted.

[0111] In the example illustrated in figure 3B , with implementation of the invention, if the current value RSRPc is associated with a quality level of the downstream radio link lower than the first value RSRP1, the base station 21 can modify the radio quality of service configuration for the GBR flows of the CPE1 22 of the first customer site. For example, the base station 21 can modify the configuration of the processing of the GBR flows of the CPE1 22 (first configuration) in BE (second configuration). The initially GBR flows transmitted or received by the CPE1 22 of the first site therefore switch to QoS BE. An alarm can possibly be generated to inform equipment upstream of the base station 21, the operator or the customer, for example by using the APIs (“Application Programming Interface”) SCEF (“Service Capability Exposure Function”) in 4G, or NEF (“Network Exposure Function”) in 5G. The customer can use these APIs to be notified on an event for a given equipment.For example, it is possible to define and implement a notification of the type “QoS degradation GBR to BE on drop in radio quality”.

[0112] The base station 21 seeks to allocate resources as a priority to the GBR flows of the CPE2 23. The GBR flows of the CPE2 23 of the second client site are therefore served according to the initial configuration without problem. All of the BE flows share the remaining radio resources. According to this embodiment, there are still sufficient radio resources to allocate to the BE flows of the CPE1 22, CPE2 23 and terminals 24. Thus, if we denote by n the number of BE flows before “downgrading” the GBR flows transmitted or received by the CPE 22 of the first site into BE flows, and X the volume of radio resources available after allocation to the GBR flows, then the radio resources for each BE flow go from X / n (overall congestion controlled) to X / (n+1), in the case of a “Round Robin” type scheduling algorithm. We thus note that the higher the number of BE flows, the more negligible the impact. In any case, each BE stream is better served according to the invention.

[0113] If the degradation is punctual, and a new current RSRPc value measured by the CPE 22 of the first site is associated with a radio quality level greater than or equal to a second RSRP2 value, for example equal to the first RSRP1 value, a return to normal is possible.

[0114] In other words, if subsequently a current value RSRPc is associated with a quality level of the downlink radio link greater than or equal to the second value RSRP2, the base station 21 can again modify the radio quality of service configuration for the GBR flows of the CPE1 22 previously downgraded to BE flows. For example, the base station 21 modifies the configuration of the processing of these BE flows of the CPE1 22 (second configuration) to GBR (first configuration). In other words, the GBR QoS configurations are reinstalled.

[0115] An alarm can optionally be generated to inform equipment upstream of the base station 21, the operator or the customer, for example using SCEF or NE coupling as mentioned previously. In this case, it is possible to define and implement a notification of the type "QoS improvement BE to GBR on increase in radio quality".

[0116] According to a second example illustrated in figures 4A et 4B , we consider that at least one current RSRPc value measured by the CPE1 22 of the first customer site decreases sharply (for example, going from - 80dBm to -120dBm), for example following the presence of an obstacle on the transmission channel.

[0117] The cell then enters an uncontrolled GBR congestion type situation.

[0118] In the example illustrated in figure 4A , without implementing the invention, the base station 21 allocates resources to the different equipment (CPE1 22, CPE2 23, terminals 24) and seeks to provide as a priority a guaranteed target rate to the flows of the equipment benefiting from a GBR configuration (CPE1 22 and CPE2 23).

[0119] There is overconsumption of radio resources in an attempt to provide CPE1 22 with the desired guaranteed throughput. In particular, according to this example, CPE1 22 at the first site overconsumes radio resources compared to the initial setting, to the point that the theoretical volume of radio resources required for GBR flows exceeds the cell's capacity.

[0120] All or part of the GBR flows of CPE1 22 and CPE2 23 (depending on the protection mechanisms activated) are negatively degraded, the minimum guaranteed flow rates are not reached.

[0121] In addition, all BE flows are negatively impacted.

[0122] In the example illustrated in figure 4B , with implementation of the invention, if the current value RSRPc is associated with a quality level of the downstream radio link lower than the first value RSRP1, the base station 21 modifies the radio quality of service configuration for the GBR flows of the CPE1 22 of the first client site. For example, the base station 21 modifies the configuration of the processing of the GBR flows of the CPE1 22 (first configuration) in BE (second configuration). The initially GBR flows transmitted or received by the CPE1 22 of the first site therefore switch to QoS BE. An alarm may possibly be generated to inform equipment upstream of the base station 21, the operator or the client, for example by using SCEF or NEF coupling as mentioned previously, with for example a notification of the type “QoS degradation GBR to BE on drop in radio quality”.

[0123] The base station 21 seeks to allocate resources as a priority to the GBR flows of the CPE2 23. The GBR flows of the CPE2 23 of the second client site are therefore served according to the initial configuration without problem. All of the BE flows share the remaining radio resources. According to this embodiment, there are therefore sufficient radio resources to allocate to the BE flows of the CPE1 22, CPE2 23 and terminals 24. Thus, if we denote by n the number of BE flows before “downgrading” the GBR flows transmitted or received by the CPE 22 of the first site into BE flows, and X the volume of radio resources available after allocation to the GBR flows, then the radio resources for each BE flow go from X / n (overall congestion controlled) to X / (n+1), in the case of a “Round Robin” type scheduling algorithm. We thus note that the higher the number of BE flows, the more negligible the impact. In all cases, BE flows are preserved.

[0124] If the degradation is punctual, and a new current RSRPc value measured by the CPE 22 of the first site is associated with a radio quality level greater than or equal to a second RSRP2 value, for example equal to the first RSRP1 value, a return to normal is possible.

[0125] In other words, if subsequently a current value RSRPc is associated with a quality level of the downlink radio link greater than or equal to the second value RSRP2, the base station 21 can again modify the radio quality of service configuration for the GBR flows of the CPE1 22 previously downgraded to BE flows. For example, the base station 21 modifies the configuration of the processing of these BE flows of the CPE1 22 (second configuration) to GBR (first configuration). In other words, the GBR QoS configurations are reinstalled.

[0126] An alarm may optionally be generated to inform equipment upstream of the base station 21, the operator or the customer, for example using SCEF or NEF coupling as mentioned previously, with for example a notification of the type “QoS improvement BE to GBR on increase in radio quality”.

[0127] Thus, according to the examples presented above, the proposed solution can help to provide guaranteed QoS on 4G or 5G to a customer for the connectivity of one of its customer sites, if the available resources allow it. The negotiated parameters of the QoS can be kept as long as the quality of the radio link between the antenna of the customer site (CPE1 22 of the first customer site) and the base station is greater than or equal to the first value, and therefore “acceptable” by the operator.

[0128] As previously indicated, in certain embodiments, a radio link quality acceptability threshold may be defined, and the base station, or the operator, verifies that the first value is indeed associated with a quality level greater than or equal to the acceptability threshold.

[0129] The notion of "acceptability" of the radio link may, for example, depend on a compromise between the load in the cell, the guaranteed throughput and the quality of the radio link. If the quality of the radio link degrades excessively (outside the acceptability window defined by the operator), for example, construction of a wall, relocation of the antenna on the customer site, tree, etc.), the QoS parameters can be renegotiated and revised downwards. The customer and the operator can be warned, and thus take appropriate decisions and actions.

[0130] For example, “long-term” actions can be put in place between the operator and the customer if the quality of the radio link remains degraded for a long period (for example for a period exceeding 24 hours): decrease of the previously negotiated guaranteed flow rate; cancellation of the guaranteed flow rate and negotiation of a relative priority; cancellation of the guaranteed flow rate, the negotiated QoS of the flow becomes BE; cancellation of the relative priority, the negotiated QoS of the flow becomes BE; etc. 5.3 Variants

[0131] An exemplary embodiment has been described above in which the radio link quality values are customer equipment received power (RSRP) values.

[0132] Alternatively, radio link quality values can be an indicator of CQI channel quality.

[0133] So, according to the example illustrated in figure 5 , the base station 51 can receive, from the core network 50, the command to create a dedicated bearer for a first configuration (501), for example a GBR configuration for a type of flow, as well as a first value of the radio link between the base station 51 and the CPE1 52 (502), corresponding to the initial CQI, noted CQI1. The base station 51 can allocate resources to the CPE1 52 using the dedicated bearer for the GBR configuration (511).

[0134] The CPE1 52 can perform one or more measurements of the quality of the radio link in the downstream direction, and send the current CQI, noted CQlc, to the base station 51 (521, 522, 523).

[0135] As long as the current CQI has a radio quality level greater than or equal to the initial CQI (521, 522) (CQIc ≥ CQI1), the dedicated bearer for the BGR configuration of CPE1 52 is not modified.

[0136] On the other hand, if the current CQI has a radio quality level lower than the initial CQI (521, 522), the base station 51 can send an alert (512) to the core network 50. The base station 51 can receive the command from a dedicated bearer for a second configuration (503), for example a GBR configuration with a guaranteed throughput lower than that of the first configuration.

[0137] Base station 51 can allocate resources to CPE1 52 using the new bearer (513).

[0138] Furthermore, examples have been described above in which the client equipment is fixed equipment, for example enabling FWA access. In other embodiments, the client equipment may be a mobile terminal.

[0139] In this case, the method described above can be implemented when the terminal stabilizes in the cell (in the radio and / or geographical sense), in particular to obtain the first value if it is determined from a measurement of the quality of the radio link. A terminal in motion could therefore see its connectivity (i.e. its flow rate) change from GBR to non-GBR then GBR, etc., depending on the characteristics of the cells crossed and its position in the cell. 5.4 Simplified structures of a base station and client equipment

[0140] We now present, in relation to the figure 6 , the simplified structure of a base station according to at least one embodiment described above.

[0144] Finally, we present, in relation to the figure 7 , the simplified structure of a client equipment according to at least one embodiment described above.

[0145] As illustrated in figure 7 , such client equipment, comprises at least one memory 71 comprising a buffer memory, at least one processing unit 72, equipped for example with a programmable computing machine or a dedicated computing machine, for example a processor P, and controlled by the computer program 73, implementing steps of the communication management method according to at least one embodiment of the invention.

[0146] Upon initialization, the code instructions of the computer program 73 are for example loaded into a RAM memory before being executed by the processor of the processing unit 72.
