[0037] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0038] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0039] The resource allocation method provided in the embodiment of the present application can be applied in the application environment shown in Figure 1. Among them, the base station 104 is a device deployed in the access network to provide wireless communication functions for the terminal 102. In systems using different wireless access technologies, the name of the device with base station functions may be different. For example, in the LTE system, it is called an evolved Node B (eNodeB) or eNB; in the 5G New Radio (NR) system, it is called a gNodeB or gNB. Wireless communication can be carried out between the terminal 102 and the base station 104. The terminal 102 can be a smartphone, tablet computer, personal computer, laptop computer, wearable device, vehicle-mounted device, etc. The base station 104 can be any type of base station device such as a macro base station, a micro base station or a pico base station.

[0040] Currently, 5G networks define three service types: Ultra-Reliable and Low Latency Communications (URLLC), Enhanced Mobile Broadband (eMBB), and Massive Machine-Type Communications (eMTC). Each service has different latency and rate requirements, leading to the coexistence and scheduling of multiple services within the same network. The communication protocol does not specify resource allocation for these three services, leaving it up to each vendor to implement independently. When a high-priority service (for example, a latency-critical URLLC service) requires resource allocation but no idle resources are available, the network preempts resources allocated to a lower-priority service (for example, a latency-relatively lenient eMBB service) to allow the higher-priority service to use them. This can cause service interruptions for the preempted lower-priority service. Furthermore, if resources allocated to the lower-priority service are concentrated in the preemption area, this can cause prolonged service interruptions for the lower-priority service. Based on this, the present application proposes a resource allocation method, device, base station, readable storage medium and program product, which can avoid the problem of long-term service interruption of services whose resources are preempted.

[0041] In one embodiment, as shown in FIG2 , a resource allocation method is provided, which is described by taking the method applied to the base station in FIG1 as an example, including the following steps:

[0042] S201 , when a first service needs to seize resources of a second service, allocate the reserved resources of the second service to the first service; the priority of the first service is higher than that of the second service.

[0043] Among them, the first service is a high-priority service, and the second service is a low-priority service. High-priority service refers to services with strict latency requirements, such as URLLC services, and low-priority service refers to services with relatively loose latency requirements, such as eMBB services.

[0044] It should be noted that the terminal will carry the Quality of Service (QoS) parameters when initiating a service. The base station can determine whether the service is a high-priority service based on the QoS parameters. For example, the base station can determine whether there is a terminal access for URLLC service in the network, or whether there is a terminal access for autonomous driving V2X service based on the QoS parameters. If there is terminal access for these services, or the terminal initiates these services, it is considered that a high-priority service is being carried out.

[0045] Furthermore, when the base station determines that a high-priority first service is accessed in the network, if there are no resources allocated to the first service in the network, the base station can determine that the reserved resources of the low-priority second service need to be allocated to the high-priority first service. At this time, the base station can allocate the reserved resources of the second service to the first service.

[0046] S202: Switch the second service to target resources; the target resources are resources other than the reserved resources.

[0047] In this embodiment, after the base station allocates the reserved resources of the second service to the first service, the first service can be operated using the allocated reserved resources. In addition, the second service can be switched to target resources other than the above-mentioned reserved resources so that the second service can continue to operate using the switched target resources, thereby avoiding the problem of service interruption of the second service due to the allocation of resources to the first service.

[0048] Optionally, in this embodiment, the base station can switch the second service to a target resource other than the reserved resources through a radio resource control (RRC) connection reconfiguration message, or can switch the second service to a target resource other than the reserved resources through downlink control information (DCI).

[0049] Optionally, in this embodiment, the base station may allocate all reserved resources for the second service to the high-priority first service, or may allocate part of the reserved resources for the second service to the high-priority first service. This embodiment does not impose any restrictions on the reserved resources allocated to the first service.

[0050] In the above resource allocation method, when a high-priority first business needs to preempt the resources of a low-priority second business, the reserved resources of the second business are allocated to the first business, and the second business is switched to target resources other than the reserved resources. In this way, the first business can continue to run using the allocated reserved resources, and the second business can continue to run using the switched target resources. While ensuring that the first business can run, the problem of long-term business interruption after the resources of the second business are allocated to the first business is avoided, and the second business can achieve business continuity on other resources.

[0051] In the above scenario of allocating the reserved resources of the second service to the first service and switching the second service to the target resources, it is necessary to pre-allocate the reserved resources and the target resources to the second service. In one embodiment, the above method further includes: step A, allocating the reserved resources to the target terminal corresponding to the second service within the preemption area, and allocating the target resources to the target terminal outside the preemption area; the preemption area includes the reserved frequency domain resources.

[0052] In this embodiment, the preemption area is a reserved frequency domain resource pre-determined from the total frequency domain resources of the network. That is, the base station may determine a portion of the frequency domain resources within the total frequency domain resources of the network as the preemption area. Further, it can be understood that the base station allocates reserved resources to the target terminal corresponding to the second service within the preemption area. That is, the reserved resources allocated by the base station to the target terminal corresponding to the second service are frequency domain resources determined from the reserved frequency domain resources included in the preemption area.

[0053] The specific implementation method for determining the preemption area is described below:

[0054] First, the base station can determine the above-mentioned preemption area based on the total frequency domain resources of the network and the preset preemption resource ratio. For example, the preset preemption resource ratio can be 5%, that is, the base station can determine 5% of the total frequency domain resources of the network as the above-mentioned preemption area.

[0055] The second type: the base station can determine the above-mentioned preemption area from the total frequency domain resources of the network based on the amount of resources corresponding to the first service in the historical time period. For example, the base station can determine the above-mentioned preemption area based on the peak value of the frequency domain resources used by the high-priority first service unit time in the past week. Exemplarily, the base station can determine the peak value of the frequency domain resources used by the first service unit time in the past week in the total frequency domain resources of the network as the above-mentioned preemption area, or the base station can determine the above-mentioned preemption area from the total frequency domain resources of the network according to the proportion of the peak value of the frequency domain resources used by the first service unit time in the past week to the total frequency domain resources of the network.

[0056] It should be noted that Bandwidth Part (BWP) is a technology introduced in the 5G network, which allows the terminal to work on a certain frequency (BWP) in the entire 5G frequency band. The bandwidth of 5G is large. If each terminal monitors the channel and transmits data within the entire bandwidth, this will also cause terminal power consumption. In addition, on each BWP, different carrier intervals can be set to meet the needs of different services. The BWP of each terminal is allocated by the base station equipment. Multiple BWPs can be allocated, but only one can be activated. The reserved resources and target resources in this embodiment are multiple BWPs allocated to the target terminal. Optionally, in this embodiment, the base station can allocate the above-mentioned reserved resources to the target terminal in the preemption area and allocate the above-mentioned target resources to the target terminal outside the preemption area according to the allocation strategy that the frequency band of the allocated reserved resources does not overlap with the frequency band of the allocated target resources.

[0057] In this embodiment, the base station allocates reserved resources to the target terminal corresponding to the second service within the preemption area including the reserved frequency domain resources, and allocates target resources to the target terminal outside the preemption area. This ensures that when a high-priority first service in the network requires allocation of reserved resources for the second service, the second service can be switched to the target resources outside the preemption area to ensure the continued operation of the second service and avoid service interruption or even long-term service interruption of the second service.

[0058] This embodiment will describe the detailed process of determining the target terminal corresponding to the second service. In one embodiment, the method further includes: step B, determining the target terminal from each terminal according to capability reporting information of each terminal in the network.

[0059] First of all, it should be noted that the 3rd Generation Partnership Project (3GPP) protocol specification stipulates that if the terminal supports resources being preempted, the terminal will report pre-EmptIndication-DL under the New Radio (NR) physical layer capability Phy-Parameters to inform the network that its own supported resources are preempted. In this embodiment, as an optional implementation method, the base station can determine the terminal that reports pre-EmptIndication-DL capability information as the target terminal based on the capability reporting information of each terminal in the network.

[0060] As an optional implementation, before determining the target terminal from each terminal based on the capability reporting information of each terminal in the network, the base station may first determine whether the base station needs to allocate frequency domain resources within the above-mentioned preemption area based on the number of terminals in the network or the frequency domain resource range of the network. If the base station determines that the frequency domain resources within the above-mentioned preemption area need to be allocated, the base station may then determine the target terminal from each terminal based on the capability reporting information of each terminal. For example, the base station may determine whether the base station needs to allocate frequency domain resources within the above-mentioned preemption area based on whether the number of terminals in the network exceeds the network capacity. That is, if the number of terminals in the network exceeds the network capacity, the base station may determine that the frequency domain resources within the above-mentioned preemption area need to be allocated. As another example, the base station may determine whether the frequency domain resources within the above-mentioned preemption area need to be allocated based on whether the frequency domain resource range currently required by all terminals in the network is greater than the total frequency domain resource range of the network. That is, when the frequency domain resource range currently required by all terminals in the network is greater than the total frequency domain resource range of the network, the base station may determine that the frequency domain resources within the above-mentioned preemption area need to be allocated. Furthermore, when the base station determines that frequency domain resources within the preemption zone need to be allocated, the base station may perform the above-mentioned step of determining a target terminal from each terminal based on the capability reported by each terminal. It is understood that when the base station determines that frequency domain resources within the reserved preemption zone need to be allocated, the base station determines a target terminal from each terminal based on the capability reported by each terminal, thereby avoiding waste of resources.

[0061] In this embodiment, the base station reports information based on the capabilities of each terminal, and the process of determining the target terminal from each terminal is relatively simple and does not require excessive complex calculations, so that the target terminal can be quickly determined from each terminal in the network, thereby improving the efficiency of determining the target terminal.

[0062] In some scenarios, the base station may first determine whether to allocate the reserved resources of the low-priority second service to the first service based on whether there are available frequency domain resources in the preemption area. In one embodiment, as shown in FIG3 , the method further includes:

[0063] S301: Determine whether there are available frequency domain resources in the preemption area.

[0064] The available frequency domain resources may include idle frequency domain resources in the preempted area and remaining frequency domain resources in the preempted area.

[0065] Optionally, in this embodiment, the base station may determine whether there are available frequency domain resources in the preemption area based on the current network resource load. For example, if the current network resource load is not severe, it may be determined that the frequency domain resources in the preemption area are not completely occupied, and that there are available frequency domain resources in the preemption area. If the current network resource load is severe, it may be determined that the frequency domain resources in the preemption area are completely occupied, and that there are no available frequency domain resources in the preemption area.

[0066] S302: If there are no available frequency domain resources in the preemption area, it is determined that the reserved resources of the second service need to be allocated to the first service.

[0067] In this embodiment, if the base station determines that there are no available frequency domain resources in the above-mentioned preemption area, it means that there are no available frequency domain resources in the reserved frequency domain resources. In order to ensure the operation of the high-priority first service, the base station needs to allocate the reserved resources of the low-priority second service to the first service.

[0068] Optionally, as another possible scenario, the base station may also determine that there are available frequency domain resources in the preemption area. In this case, the base station may allocate the available frequency domain resources in the preemption area to the high-priority first service, so that the high-priority service can run. It is understandable that when there are available frequency domain resources in the preemption area, the base station allocates the available frequency domain resources in the preemption area to the priority first service, which can reduce unnecessary resource preemption, while also ensuring the operation of the low-priority second service, avoiding service interruption of the second service.

[0069] In this embodiment, the base station determines whether there are available frequency domain resources in the preemption area. If it is determined that there are no available frequency domain resources in the preemption area, it determines that the reserved resources of the low-priority second service need to be allocated to the first service. This can reduce unnecessary resource preemption, ensure that both the first service and the second service can operate normally, and avoid service interruption of the low-priority second service.

[0070] In a scenario where the base station allocates the reserved resources of the low-priority second service to the second service and the second service needs to be switched to the target resources, whether the second service needs to be switched to the target resources can be determined based on a preset preemption parameter. As shown in FIG4 , in one embodiment, the above S202 includes:

[0071] S401 , determining whether to switch the second service to the target resource according to a preemption parameter; the preemption parameter includes any one of a duration for preempting the reserved resource, a number of preempting the reserved resource, and a service type of the second service.

[0072] The preemption parameter includes any one of the duration of preempting the reserved resources of the second service, the number of times the reserved resources of the second service are preempted, and the service type of the second service. The following will respectively describe in detail the implementation methods of determining whether to switch the second service to the target resource based on the preemption parameter:

[0073] The first one is that, when the preemption parameter is the duration of preempting the reserved resources for the second service, if the preemption of the reserved resources for the second service is a short-term preemption, the base station can determine not to switch the second service to the target resources; if the preemption of the reserved resources for the second service is a long-term preemption, the base station can determine to switch the second service to the target resources.

[0074] The second type is that when the preemption parameter is the number of times the reserved resources for the second service are preempted, if the preemption of the reserved resources for the second service is a low-frequency preemption, the base station can determine not to switch the second service to the target resources; if the preemption of the reserved resources for the second service is a high-frequency preemption, the base station can determine to switch the second service to the target resources.

[0075] The third type is that when the preemption parameter is the service type of the second service, if the second service is not in operation, or the second service is a low-rate service, the base station can determine not to switch the second service to the target resource; if the second service is in operation, or the second service is a high-rate service, the base station can determine to switch the second service to the target resource.

[0076] S402: If it is determined to switch the second service to the target resource, the second service is switched to the target resource.

[0077] In this embodiment, if the base station determines to switch the second service to the target resource, the base station may perform the above-mentioned step of switching the second service to the target resource. That is, the base station may switch the second service to the target resource other than the reserved resource through the RRC connection reconfiguration message, or the base station may switch the second service to the target resource other than the reserved resource through the DCI information.

[0078] In this embodiment, the process of the base station determining whether to switch the second service to the target resource based on the preemption parameters is relatively simple. The base station can quickly determine whether to switch the second service to the target resource. Therefore, the base station can quickly switch the second service to the target resource when it determines to switch the second service to the target resource, ensuring the timeliness of the second service switching to the target resource, ensuring the business continuity of the second service, and avoiding business interruption problems of the second service.

[0079] In the scenario where the base station allocates the reserved resources of the low-priority second service to the first service, the base station may allocate the reserved resources with higher signal strength among the reserved resources of the low-priority second service to the first service. As shown in FIG5 , in one embodiment, the above S202 includes:

[0080] S501: Obtain signal strength of a terminal corresponding to a first service within reserved resources.

[0081] Typically, a terminal periodically reports a cell signal measurement report. Therefore, the base station can obtain the signal strength of the terminal within the cell resources based on the measurement report reported by the terminal.

[0082] Optionally, in this embodiment, the base station may obtain the signal strength of the terminal corresponding to the first service within the reserved resources based on the signal measurement report within the reserved resources reported by the terminal corresponding to the first service. Optionally, the signal strength of the terminal corresponding to the first service within the reserved resources obtained by the base station may be greater than a preset strength threshold, or may be less than or equal to the preset strength threshold, which is not limited in this embodiment.

[0083] S502: Allocate reserved resources whose signal strength is greater than a preset strength threshold to a first service.

[0084] In this embodiment, the base station may compare the acquired signal strength of the terminal corresponding to the first service within the reserved resources with a preset strength threshold, and allocate the reserved resources with signal strength greater than the preset strength threshold to the first service. In other words, in this embodiment, the base station allocates the reserved resources with better signal conditions among the preempted reserved resources to the first service.

[0085] In this embodiment, the base station obtains the signal strength of the terminal corresponding to the first service within the reserved resources of the second service, and can determine the reserved resources with signal strength greater than the preset strength threshold. The reserved resources with signal strength greater than the preset strength threshold can then be allocated to the first service, ensuring that the first service can operate normally and improving the reliability of the operation of the first service.

[0086] To facilitate understanding by those skilled in the art, as shown in FIG6 , the resource allocation method provided by this application is described in detail below in conjunction with a complete embodiment:

[0087] S1: The base station reserves a portion of frequency domain resources as the preemption area.

[0088] S2: The base station allocates frequency domain resources to each terminal in the network.

[0089] S3: The base station determines whether it is necessary to allocate frequency domain resources in the reserved preemption area according to the number of terminals in the network or the frequency domain resource range of the network.

[0090] S4. If the base station determines that the frequency domain resources in the reserved preemption area need to be allocated, the base station determines the target terminal to which the reserved resources can be allocated from the terminals according to the capability reporting information of each terminal in the network.

[0091] S5, according to a preset allocation strategy, allocate reserved resources to the target terminal to which reserved resources can be allocated in the preemption area, and allocate target resources to the target terminal outside the preemption area; wherein the preset allocation strategy includes that the frequency band of the reserved resources does not overlap with the frequency band of the target resources.

[0092] S6: When a high-priority service appears in the network, it is determined whether a preemption operation is required.

[0093] S7, when it is determined that a preemption operation is required, the reserved resources of the target terminal are allocated to the high priority service, and at the same time, resources of the target terminal are switched to target resources other than the reserved resources.
