Description

Technical Field

[0001] The present invention relates to the field of communication technologies, and in particular, to a service scheduling method, apparatus, device, and storage medium. Background Art

[0002] With the booming development of the mobile Internet, the contradiction between the explosive demand for high-bandwidth wireless services by the public and the scarcity of spectrum resources has become increasingly acute. As a supplement to licensed spectrum, unlicensed spectrum still has rich resources and great development space. Taking the 5GHz band as an example, the total unlicensed spectrum resources allocated in various countries around the world currently exceed 500MHz. Among them, unlicensed spectrum refers to the spectrum that can be directly used without authorization under the relevant regulations of government departments.

[0003] In the related art, in the solution of sharing a 200MHz shared carrier in 5G SA (Standalone), the licensed spectrum resources of this carrier are dynamically shared by the co-constructed operators, and it is difficult for users of a single operator to reach the maximum peak rate of 200MHz.

[0004] When the number of users or the volume of services of an operator is large, traffic congestion problems will occur, thus affecting the user experience. Summary of the Invention

[0033] The second scheduling sub-module is used to, if the spectrum resources required by any operator meet the second condition, schedule the services of each target user belonging to the operator on the authorized spectrum and the predetermined unlicensed spectrum, and schedule the services of each target user belonging to other operators on the unlicensed spectrum; wherein, the second condition is the total amount of spectrum resources greater than the authorized spectrum.

[0034] The third scheduling sub-module is used to, otherwise, schedule the services of each target user belonging to the first operator on the authorized spectrum, and schedule the services of each target user belonging to the second operator on the authorized spectrum or the predetermined unlicensed spectrum; wherein, the first operator is the operator with the most required spectrum resources, and the second operator is the operator other than the first operator.

[0039] Advantages of the embodiments of the present invention:

[0040] The solution provided by the embodiments of the present invention first determines the total amount of spectrum resources required to send the services of each target user. Then, it judges whether the total amount of the spectrum resources exceeds the size of the spectrum resources of the preset shared carrier. If so, the services of each target user are scheduled on the authorized spectrum and the predetermined unlicensed spectrum in a preset scheduling manner; otherwise, the services of each target user are scheduled on the authorized spectrum. It can be seen that in this solution, when the total amount of spectrum resources required to send the services of each target user is greater than the size of the spectrum resources of the preset shared carrier, by introducing the unlicensed spectrum, the services are scheduled on the authorized spectrum and the predetermined unlicensed spectrum, solving the traffic congestion problem caused by a large number of users or a large amount of services.

[0041] Of course, it is not necessary for any product or method implementing the present invention to achieve all the above-mentioned advantages at the same time. Description of the Drawings

[0042] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the following will briefly introduce the drawings required for the description of the embodiments or the prior art. Obviously, the drawings in the following description are only some embodiments of the present invention. For those of ordinary skill in the art, other embodiments can also be obtained based on these drawings.

[0048] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art based on this application belong to the scope of protection of the present invention.

[0049] In the related art, in the 5G SA co-construction and sharing 200MHz shared carrier solution, the authorized spectrum resources of this carrier are dynamically shared by the co-constructed operators. It is very difficult for users of a single operator to reach the maximum peak rate of 200MHz through the way of CA (Carrier Aggregation) or DC (Dual-connectivity).

[0050] With the explosion of the public's demand for high-bandwidth wireless services, when the number of users or the volume of services of the operator is large, more spectrum resources are needed for service scheduling. However, due to the limited spectrum resources of the shared carrier co-constructed by the operator, traffic congestion problems will occur during service scheduling, seriously affecting the user experience.

[0051] Based on the above content, in order to solve the traffic congestion problem caused by a large number of operator users or a large volume of services, the embodiments of the present invention provide a service scheduling method, device, equipment, and storage medium.

[0052] First, a service scheduling method provided by an embodiment of the present invention will be introduced below.

[0053] A service scheduling method provided by an embodiment of the present invention can be applied to an electronic device. In a specific application, the electronic device can be a server or a terminal device, which is reasonable. In actual applications, the terminal device can be a scheduling console, a tablet computer, a desktop computer, and so on.

[0054] Specifically, the execution subject of the service scheduling method can be a service scheduling device. Exemplarily, when the service scheduling method is applied to a terminal device, the service scheduling device can be a functional software running on the terminal device, such as service scheduling software. Exemplarily, when the service scheduling method is applied to a server, the service scheduling device can be a computer program running on the server, and the computer program can be used for service scheduling.

[0055] In addition, it should be noted that in the actual application of 5G SA, the service scheduling device can be installed on the 5G core network side or the 5G base station side. It can be understood that installing the service scheduling device on the base station side can reduce the delay caused by the service scheduling device sending scheduling decision instructions, thereby improving the service scheduling speed.

[0056] Among them, a service scheduling method provided by an embodiment of the present invention may include the following steps:

[0057] Determine the total amount of spectrum resources required for sending the services of each target user, where the target user is a user of an operator sharing a carrier and waiting to send a service;

[0058] Judge whether the total amount of the spectrum resources exceeds the size of the spectrum resources of a preset shared carrier; where the spectrum resources of the shared carrier are the spectrum resources of authorized spectrum;

[0059] If so, schedule the services of each target user on the authorized spectrum and a predetermined unlicensed spectrum in a preset scheduling manner; where the preset scheduling manner is a service scheduling manner set for each operator sharing a carrier;

[0060] Otherwise, schedule the services of each target user on the authorized spectrum.

[0061] In the solution provided by the embodiments of the present invention, first, determine the total amount of spectrum resources required for the services of each target user; then, determine whether the total amount of the spectrum resources exceeds the size of the spectrum resources of a preset shared carrier; if so, schedule the services of each target user on the licensed spectrum and a predetermined unlicensed spectrum in a preset scheduling manner; otherwise, schedule the services of each target user on the licensed spectrum. It can be seen that in this solution, when the total amount of spectrum resources required for the services of each target user is greater than the size of the spectrum resources of the preset shared carrier, by introducing the unlicensed spectrum, the services are scheduled on the licensed spectrum and the predetermined unlicensed spectrum, thus solving the traffic congestion problem caused by a large number of users or a large amount of services.

[0062] Next, the service scheduling method provided by the embodiments of the present invention will be introduced with reference to the accompanying drawings.

[0063] As Figure 1 shown, the service scheduling method provided by the embodiments of the present invention may include steps S101 - S104:

[0064] S101, determine the total amount of spectrum resources required for the services of each target user, where the target user is a user of an operator sharing a shared carrier and waiting to send services;

[0065] In this embodiment, when multiple operators share a shared carrier, the spectrum resources of the shared carrier are shared by the operators building the carrier. It can be understood that since the spectrum resources of the shared carrier jointly built by the operators are limited, therefore, when sending the services of each target user, in order to reasonably allocate the limited spectrum resources, the total amount of spectrum resources required for the services of each target user may be determined first. Exemplarily, the size of the spectrum resources required for sending the service of any one of the target users may be the bandwidth size required for sending the service. Among them, the service of any one of the target users may be a call service, a video download service, and so on.

[0066] It should be noted that each operator has its own licensed spectrum. When multiple operators share a shared carrier, their respective spectrum resources can be shared by the operators participating in the construction. Exemplarily, if Operator A and Operator B jointly build a 200 MHz shared carrier, then the 200 MHz spectrum resources of the shared carrier are dynamically shared by Operator A and Operator B.

[0067] S102, determine whether the total amount of the spectrum resources exceeds the size of the spectrum resources of a preset shared carrier. If so, execute S103; otherwise, execute S104; where the spectrum resources of the shared carrier are the spectrum resources of the licensed spectrum;

[0068] After determining the total amount of spectrum resources required for the services of each target user through step S101, it is possible to judge the total amount of the spectrum resources, so as to facilitate the subsequent decision on whether to introduce unlicensed spectrum for service scheduling. Exemplarily, if the size of the spectrum resources of the preset shared carrier is 200 MHz, it is judged whether the total amount of the spectrum resources required for the services of each target user exceeds 200 MHz, so as to be used for the subsequent decision on whether to introduce unlicensed spectrum for service scheduling.

[0069] It should be noted that in practical applications, each operator has the spectrum resources of the pre-applied licensed spectrum, and the spectrum resources of the licensed spectrum are only used by the operator that applies for the resources. When building and sharing a carrier, the spectrum resources of the licensed spectrum can be shared by the operators that build the shared carrier; while the spectrum resources of the unlicensed spectrum are shared by the public and need to be preempted when used.

[0070] S103, schedule the services of each target user on the licensed spectrum and the predetermined unlicensed spectrum in a preset scheduling manner; wherein, the preset scheduling manner is the service scheduling manner set for each operator that builds and shares the carrier;

[0071] In this embodiment, scheduling the services of each target user on the licensed spectrum and the predetermined unlicensed spectrum means allocating the available spectrum resources of the licensed spectrum and the unlicensed spectrum for the services to be sent of each target user. It can be understood that if the total amount of the above spectrum resources exceeds the size of the spectrum resources of the preset shared carrier, when using the spectrum resources of the shared carrier for service scheduling, due to insufficient spectrum resources, there will be a problem of traffic congestion. Therefore, unlicensed spectrum can be introduced, that is, the services to be sent are scheduled on the licensed spectrum and the predetermined unlicensed spectrum to solve the problem of traffic congestion. Among them, the predetermined unlicensed spectrum can be a predetermined size of unlicensed spectrum that is activated when in use.

[0072] Optionally, in one implementation manner, scheduling the services of each target user on the licensed spectrum and the predetermined unlicensed spectrum in a preset scheduling manner may include steps A1 - A4:

[0073] A1, for each operator to which each target user belongs, determine the spectrum resources required by the operator according to the spectrum resources required by the services of the target users belonging to the operator;

[0074] It can be understood that for the operators that build and share a carrier, the allocation of spectrum resources can follow the "egalitarianism", that is, evenly allocate the spectrum resources for the target users of each operator to ensure the fairness of the allocation. Therefore, in this implementation manner, it is possible to first determine the spectrum resources required by the services of the target users belonging to each operator among each target user.

[0075] A2. If the spectrum resources required by each operator meet the first condition, the services of each target user that belong to each operator are evenly scheduled on the authorized spectrum and the predetermined unlicensed spectrum; where the first condition is greater than the total amount of spectrum resources of the unlicensed spectrum and less than the total amount of spectrum resources of the authorized spectrum.

[0076] It can be understood that if the spectrum resources required by each operator meet the first condition, and the services of each target user that belong to each operator are evenly scheduled on the authorized spectrum and the predetermined unlicensed spectrum, the fairness of spectrum resource allocation can be ensured. Exemplarily, if the total amount of spectrum resources of the unlicensed spectrum is 100 MHz, the total amount of spectrum resources of the authorized spectrum is 200 MHz, and the spectrum resources required by each operator meet the first condition, that is, within (100 MHz, 200 MHz), then the services that belong to each operator are evenly scheduled on the authorized spectrum and the predetermined unlicensed spectrum, which can ensure the fairness of spectrum resource allocation.

[0077] A3. If the spectrum resources required by any one operator meet the second condition, the services of each target user that belong to this operator are scheduled on the authorized spectrum and the predetermined unlicensed spectrum, and the services of each target user that belong to other operators are scheduled on the unlicensed spectrum; where the second condition is greater than the total amount of spectrum resources of the authorized spectrum.

[0078] It can be understood that if the spectrum resources required by any one operator meet the second condition, then the spectrum resources of the authorized spectrum are not enough for the services of this operator. At this time, spectrum resources of the unlicensed spectrum also need to be allocated for the services of this operator, and at this time, all the spectrum resources of the authorized spectrum are allocated to this operator to avoid a large number of services being blocked due to the occupation of the unlicensed spectrum.

[0079] Exemplarily, if the total amount of spectrum resources of the unlicensed spectrum is 100 MHz, the total amount of spectrum resources of the authorized spectrum is 200 MHz, and the spectrum resources required by a certain operator meet the second condition, that is, greater than 200 MHz, then the services that belong to this operator are scheduled on the authorized spectrum and the predetermined unlicensed spectrum, and the services of other operators are scheduled on the unlicensed spectrum.

[0080] A4. Otherwise, the services of each target user that belong to the first operator are scheduled on the authorized spectrum, and the services of each target user that belong to the second operator are scheduled on the authorized spectrum or the predetermined unlicensed spectrum; where the first operator is the operator that requires the most spectrum resources, and the second operator is the operator other than the first operator.

[0081] It can be understood that scheduling the services of the operator with the most required spectrum resources among each operator on the authorized spectrum can ensure the timely transmission of such a large amount of services, so as to avoid the problem of traffic congestion caused by the preemption of the unlicensed spectrum when it calls the unlicensed spectrum.

[0082] In addition, the second operator is the operator other than the first operator among the operators to which each target user belongs. Since the second operator requires less spectrum resources, the remaining available spectrum resources in the authorized spectrum except for the spectrum resources occupied by the first operator, and the spectrum resources of the unlicensed spectrum can be allocated to it.

[0083] S104, schedule the services of each target user on the authorized spectrum.

[0084] It can be understood that if the total amount of spectrum resources required to send the services of each target user does not exceed the size of the spectrum resources of the preset shared carrier, the spectrum resources of the shared carrier are sufficient to be allocated to the services to be sent by the operator. At this time, there is no need to introduce additional unlicensed spectrum, and directly schedule the services to be sent by each target user on the authorized spectrum.

[0085] In the solution provided by the embodiment of the present invention, first, determine the total amount of spectrum resources required to send the services of each target user; then, judge whether the total amount of the spectrum resources exceeds the size of the spectrum resources of the preset shared carrier; if so, schedule the services of each target user on the authorized spectrum and the predetermined unlicensed spectrum in a preset scheduling manner; otherwise, schedule the services of each target user on the authorized spectrum. It can be seen that in this solution, when the total amount of spectrum resources required to send the services of each target user is greater than the size of the spectrum resources of the preset shared carrier, by introducing the unlicensed spectrum, the services are scheduled on the authorized spectrum and the predetermined unlicensed spectrum, and the problem of traffic congestion caused by a large number of users or a large amount of services is solved.

[0086] Optionally, in one implementation manner, before scheduling the services of each target user on the authorized spectrum and the predetermined unlicensed spectrum in a preset scheduling manner, the method further includes:

[0087] Activate the unlicensed spectrum of a preset size as the predetermined unlicensed spectrum; where the preset size is a value representing the size of its spectrum resources.

[0088] It can be understood that since the spectrum resources of the unlicensed spectrum are shared by the public, when using them, it is necessary to preempt the spectrum resources of the unlicensed spectrum. Therefore, before scheduling the services of each target user in a preset scheduling manner, it is necessary to activate an unlicensed spectrum of a preset size, that is, apply for the spectrum resources of the unlicensed spectrum of the preset size, and then call the unlicensed spectrum of the preset size. Exemplarily, the preset size can be 100 MHz, 200 MHz, and so on.

[0089] It can be seen that through this implementation method, before using the unlicensed spectrum, an unlicensed spectrum of a preset size is activated, and subsequently, the services of the target users can be scheduled on the unlicensed spectrum of the preset size.

[0090] Optionally, in another embodiment of the present invention, before activating the unlicensed spectrum of the preset size as a predetermined unlicensed spectrum, it further includes:

[0091] Listening to whether the unlicensed spectrum of the preset size is occupied;

[0092] If it is not occupied, perform the step of activating the unlicensed spectrum of the preset size as a predetermined unlicensed spectrum.

[0093] It should be noted that by adopting the method of first listening to whether the unlicensed spectrum of the preset size is occupied and then activating the unlicensed spectrum, that is, the LBT (Listen Before Talk) method for the unlicensed spectrum, the services of each target user are scheduled on the licensed spectrum and the predetermined unlicensed spectrum.

[0094] It can be understood that when scheduling the services of each target user on the predetermined unlicensed spectrum, if the unlicensed spectrum is directly activated and called, since the unlicensed spectrum is shared by the public, when preempting the unlicensed spectrum, that is, when activating and calling the unlicensed spectrum, conflicts may occur, resulting in traffic congestion. To avoid conflicts when activating the unlicensed spectrum, the LBT method can be adopted. When it is monitored that the unlicensed spectrum is not occupied, the unlicensed spectrum is then activated.

[0095] In this embodiment, the LBT method of listening before transmitting for the unlicensed spectrum of the preset size means that when calling the predetermined unlicensed spectrum, first listen to whether the unlicensed spectrum is occupied by other users. If not, then activate the unlicensed spectrum of the preset size, and schedule the services of each target user on the predetermined unlicensed spectrum, so as to ensure that the unlicensed spectrum can be effectively shared. Exemplarily, the listening method can be physical carrier sensing, virtual carrier sensing, and so on.

[0096] In addition, it should be noted that if it is monitored that the unlicensed spectrum is occupied by other users, at this time, the services of each operator can be scheduled on the licensed spectrum in sequence, or wait until the unlicensed spectrum is not occupied and then schedule the services of the operator on the unlicensed spectrum. At this time, the latency of service transmission will increase to some extent.

[0097] It can be seen that through this solution, the listen-before-talk LBT method for the unlicensed spectrum of the preset size can avoid conflicts when calling the unlicensed spectrum, thus ensuring that the unlicensed spectrum can be effectively shared.

[0098] To more clearly understand the content of the embodiments of the present invention, the following will be combined with Figures 2 - 3 to introduce the present invention.

[0099] Figure 2 shows a schematic diagram of a service scheduling method. As Figure 2 shown, in the scenario where Operator A and Operator B share a 200 MHz shared carrier in 5G SA co-construction, Operator A and Operator B share the spectrum resources of 200 MHz of licensed spectrum, and the size of the spectrum resources of the unlicensed spectrum is 100 MHz. According to the user service requirements of Operator A and Operator B, that is, the spectrum resources required to send the services of each operator, the following four scheduling methods can be adopted:

[0100] (1) Scheduling method 1: When the sum of the service requirements of all users of Operator A and Operator B is less than or equal to 200 MHz, schedule the services of the users of each operator on the licensed spectrum (corresponding to scheduling the services of each target user on the licensed spectrum in the above text). At this time, the unlicensed spectrum is not activated;

[0101] (2) Scheduling method 2: When the service requirements of all users of Operator A are greater than 100 MHz and less than or equal to 200 MHz, but the service requirements of all users of Operator B are less than 100 MHz, or vice versa; then adopt the LBT method, first listen to the unlicensed spectrum. When the unlicensed spectrum is not occupied, it is necessary to activate the unlicensed spectrum (corresponding to the unlicensed spectrum of the preset size in the above text), and schedule the services of Operator A on the licensed spectrum (corresponding to scheduling the services belonging to the first operator on the licensed spectrum in the above text), and schedule the services of Operator B on the remaining spectrum resources of the unlicensed spectrum and the licensed spectrum (corresponding to scheduling the services belonging to the second operator on the licensed spectrum or the predetermined unlicensed spectrum in the above text), or vice versa;

[0102] (3) Scheduling method 3: When the service demands of all users of operator A are greater than 200 MHz and less than or equal to 300 MHz (corresponding to the second condition in the above text), but the service demands of all users of operator B are less than 100 MHz, or vice versa; then the LBT method is adopted. First, listen to the unlicensed spectrum. When the unlicensed spectrum is not occupied, it is necessary to activate the unlicensed spectrum, and schedule the services of operator A on the licensed spectrum and part of the unlicensed spectrum, and schedule the services of operator B on the unlicensed spectrum, or vice versa;

[0103] (4) Scheduling method 4: When the service demands of all users of operators A and B are both greater than 100 MHz and their sum is less than or equal to 300 MHz (corresponding to the first condition in the above text); then the LBT method is adopted. First, listen to the unlicensed spectrum. When the unlicensed spectrum is not occupied, at this time, it is necessary to activate the unlicensed spectrum, and schedule the services of operator A on the exclusive 100 MHz licensed spectrum of operator A and part of the unlicensed spectrum, and schedule the services of operator B on the exclusive 100 MHz licensed spectrum of operator B and part of the unlicensed spectrum.

[0104] Figure 3 Shows a flowchart of a specific example of the service scheduling method provided by the embodiments of the present invention. As Figure 3 shown, the workflow steps of service scheduling are as follows:

[0105] (1) The 5G SA shared base station powers on and initializes; among them, the shared base station is jointly built by operator A and operator B;

[0106] (2) Determine whether the sum of the service demands of all users of operators A and B is less than or equal to 200 MHz. If so, execute step (2a); if not, execute step (3);

[0107] (2a) Schedule the services of each operator's users on the licensed spectrum. At this time, the unlicensed spectrum is not activated.

[0108] (3) Determine whether the service demands of all users of operator A are in the range of (100 MHz, 200 MHz), and the service demands of all users of operator B are less than 100 MHz? (Or vice versa); if so, execute step (3a), if not, execute step (4);

[0109] (3a) Adopt the LBT method. First, listen to whether the unlicensed spectrum is occupied. If it is not occupied, activate the unlicensed spectrum, and schedule the services of operator A on the licensed spectrum, and schedule the services of operator B on the unlicensed spectrum, (or vice versa); if it is occupied, schedule the services of each operator's users on the licensed spectrum. At this time, the unlicensed spectrum is not activated.

[0110] (4) Determine whether the service requirements of all users of Operator A are in the range of (200 MHz, 300 MHz), and the service requirements of all users of Operator B are less than 100 MHz? (Or vice versa); if so, execute step (4a), if not, execute step (5);

[0111] (4a) Adopt the LBT method to first listen for whether the unlicensed spectrum is occupied. If it is not occupied, activate the unlicensed spectrum, schedule the services of Operator A on the licensed spectrum and part of the unlicensed spectrum, and schedule the services of Operator B on the unlicensed spectrum, (or vice versa); if it is occupied, schedule the services of users of each operator on the licensed spectrum, and at this time the unlicensed spectrum is not activated.

[0112] (5) Determine whether the service requirements of all users of Operator A and Operator B are both greater than 100 MHz, and the sum of the service requirements of all users of Operator A and Operator B is less than or equal to 300 MHz? If so, execute step (5a), if not, return to step (2);

[0113] (5a) Adopt the LBT method to first listen for whether the unlicensed spectrum is occupied. If it is not occupied, activate the unlicensed spectrum, and schedule the services of Operator A on the dedicated 100 MHz licensed spectrum of Operator A and part of the unlicensed spectrum, and schedule the services of Operator B on the dedicated 100 MHz licensed spectrum of Operator B and part of the unlicensed spectrum; if it is occupied, schedule the services of users of each operator on the licensed spectrum, and at this time the unlicensed spectrum is not activated.
