[0034] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0035] The resource allocation method provided in the embodiment of the present application can be applied to Figure 1In the application environment shown. 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 names of devices with base station functions may be different. For example, in the LTE system, it is called an evolved node (evolved Node B, eNodeB) or eNB; in the 5G new radio (New Radio, NR) system, it is called gNodeB or gNB. Wireless communication can be carried out between the terminal 102 and the base station 104. The terminal 102 can be a smart phone, a tablet computer, a personal computer, a laptop, a wearable device, a 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.

[0036] Currently, three types of services are defined in 5G networks, including Ultra-Reliable and Low Latency Communications (URLLC) services, Enhanced Mobile Broadband (eMBB) services, and Massive Machine-Type Communications (eMTC) services. Each service has different requirements for latency and rate. In the same network, there will be a phenomenon of multiple services coexisting and scheduling. The communication protocol does not stipulate the resource allocation of these three services, which is implemented independently by each manufacturer. When a high-priority service (for example, a URLLC service with strict latency requirements) needs to be allocated resources but there are no idle resources at this time, the network will preempt the low-priority service (for example, an eMBB service with relatively loose latency requirements) and preempt the resources allocated to the low-priority service for the high-priority service. This may cause the preempted low-priority service to be interrupted. Furthermore, if the resources allocated to the low-priority service are concentrated in the preemption area, the low-priority service will be interrupted for a long time. 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.

[0037] In one embodiment, Figure 2 As shown, a resource allocation method is provided, which is applied to Figure 1 The base station in FIG. 1 is taken as an example to illustrate, and the following steps are included:

[0038] S201, when a first service needs to seize resources of a second service, allocate reserved resources of the second service to the first service; the priority of the first service is higher than that of the second service.

[0039] Among them, the first service is a high-priority service, and the second service is a low-priority service. The high-priority service refers to the service with strict latency requirements, such as URLLC service, and the low-priority service refers to the service with relatively loose latency requirements, such as eMBB service.

[0040] 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 terminal access for URLLC services in the network, or whether there is terminal access for autonomous driving V2X services based on the QoS parameters. If there is terminal access for these services, or the terminal initiates these services, it is considered that high-priority services are being carried out.

[0041] 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.

[0042] S202, switching the second service to target resources; the target resources are resources other than reserved resources.

[0043] 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 the second service 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.

[0044] Optionally, in this embodiment, the base station may switch the second service to target resources other than reserved resources through a radio resource control (Radio Resource Control, RRC) connection reconfiguration message, or may switch the second service to target resources other than reserved resources through downlink control information (Downlink Control Information, DCI).

[0045] 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.

[0046] 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.

[0047] 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 allocate the reserved resources and the target resources to the second service in advance. In one embodiment, the above method further includes: step A, allocating reserved resources to the target terminal corresponding to the second service in the preemption area, and allocating target resources to the target terminal outside the preemption area; the preemption area includes reserved frequency domain resources.

[0048] In this embodiment, the preemption area is a reserved frequency domain resource determined in advance from the total frequency domain resources of the network, that is, the base station can determine a part of the frequency domain resources in the total frequency domain resources of the network as the above-mentioned preemption area. Further, it can be understood that the base station allocates reserved resources to the target terminal corresponding to the second service in 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.

[0049] The specific implementation method for determining the preemption area is described below:

[0050] 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.

[0051] 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 total frequency domain resources of the network in the past week 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 ratio 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.

[0052] 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 also 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 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, and allocate the above-mentioned target resources to the target terminal outside the preemption area.

[0053] In this embodiment, the base station allocates reserved resources to the target terminal corresponding to the second service in 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 needs to be allocated 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.

[0054] In this embodiment, the detailed process of determining the target terminal corresponding to the second service is described. In one embodiment, the method further includes: step B, determining the target terminal from each terminal according to the capability reporting information of each terminal in the network.

[0055] 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 support resources are preempted. In this embodiment, as an optional implementation, the base station can determine the terminal that reports the pre-EmptIndication-DL capability information as the target terminal based on the capability reporting information of each terminal in the network.

[0056] As an optional implementation, before the base station determines the target terminal from each terminal according to the capability reporting information of each terminal in the network, the base station may first determine whether the base station needs to allocate the frequency domain resources in the above-mentioned preempted area according to the number of terminals in the network or the frequency domain resource range of the network. When the base station determines that the frequency domain resources in the above-mentioned preempted area need to be allocated, the base station determines the target terminal from each terminal according to the capability reporting information of each terminal. For example, the base station may determine whether the base station needs to allocate the frequency domain resources in the above-mentioned preempted area according to 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 in the above-mentioned preempted area need to be allocated. As another example, the base station may determine whether the frequency domain resources in the above-mentioned preempted area need to be allocated according to 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 in the above-mentioned preempted area need to be allocated. Further, when the base station determines that the frequency domain resources in the preemption area need to be allocated, the base station can perform the above-mentioned step of determining the target terminal from each terminal according to the capability reporting information of each terminal. It can be understood that when 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 from each terminal according to the capability reporting information of each terminal, which can avoid waste of resources.

[0057] 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 too many 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.

[0058] 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. Figure 3 As shown, the above method also includes:

[0059] S301, determining whether there are available frequency domain resources in the preemption area.

[0060] The available frequency domain resources may include idle frequency domain resources in the preempted area and remaining frequency domain resources in the preempted area.

[0061] Optionally, in this embodiment, the base station can determine whether there are available frequency domain resources in the preemption area according to the current network resource load of the network. For example, if the current network resource load is not serious, it can be determined that the frequency domain resources in the preemption area are not completely occupied, and there are available frequency domain resources in the preemption area; if the current network resource load is serious, it can be determined that the frequency domain resources in the preemption area are completely occupied, and there are no available frequency domain resources in the preemption area.

[0062] 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.

[0063] 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.

[0064] Optionally, as another possible situation, the base station may also determine that there are available frequency domain resources in the above-mentioned preemption area. In this case, the base station can 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 and avoiding the problem of service interruption of the second service.

[0065] 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.

[0066] In the scenario where the base station allocates the reserved resources of the second service with a low priority to the second service and the second service needs to be switched to the target resources, it can be determined whether the second service needs to be switched to the target resources according to the preset preemption parameters, such as Figure 4 As shown, in one embodiment, the above S202 includes:

[0067] 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.

[0068] The preemption parameter includes any one of the duration of preempting the reserved resources of the second service, the number of times of preempting the reserved resources of the second service, 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 according to the preemption parameter:

[0069] 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.

[0070] 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.

[0071] The third type is that when the preemption parameter is the service type of the second service, if the second service is not in a running state, 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 a running state, or the second service is a high-rate service, the base station can determine to switch the second service to the target resource.

[0072] S402: If it is determined to switch the second service to the target resource, the second service is switched to the target resource.

[0073] 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.

[0074] In this embodiment, the process by which the base station determines 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. Thus, when the base station determines to switch the second service to the target resource, the base station can quickly switch the second service to the target resource, thereby ensuring the timeliness of switching the second service to the target resource, ensuring the service continuity of the second service, and avoiding service interruption problems of the second service.

[0075] In the above 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. Figure 5 As shown, in one embodiment, the above S202 includes:

[0076] S501: Obtain signal strength of a terminal corresponding to a first service within reserved resources.

[0077] Usually, the terminal periodically reports the signal measurement report of the cell. Therefore, the base station can obtain the signal strength of the terminal in the cell resources according to the measurement report reported by the terminal.

[0078] Optionally, in this embodiment, the base station may obtain the signal strength of the terminal corresponding to the first service in the reserved resources based on the signal measurement report in the reserved resources reported by the terminal corresponding to the first service. Optionally, the signal strength of the terminal corresponding to the first service in the reserved resources obtained by the base station may be greater than a preset strength threshold, or may be less than or equal to a preset strength threshold, which is not limited in this embodiment.

[0079] S502: Allocate reserved resources whose signal strength is greater than a preset strength threshold to a first service.

[0080] In this embodiment, the base station can compare the signal strength of the terminal corresponding to the first service in the reserved resources with the preset strength threshold, and allocate the reserved resources with signal strength greater than the preset strength threshold to the first service. That is, in this embodiment, the base station allocates the reserved resources with better signal conditions among the preempted reserved resources to the first service.

[0081] In this embodiment, the base station can determine the reserved resources with signal strength greater than the preset strength threshold by obtaining the signal strength of the terminal corresponding to the first service within the reserved resources of the second service, so that the reserved resources with signal strength greater than the preset strength threshold can be allocated to the first service, ensuring the normal operation of the first service and improving the reliability of the operation of the first service.

[0082] In order to facilitate the understanding of those skilled in the art, Figure 6 As shown, the resource allocation method provided by this application is described in detail below in combination with a complete embodiment:

[0083] S1, the base station reserves a part of the frequency domain resources as the preemption area.

[0084] S2: The base station allocates frequency domain resources to each terminal in the network.

[0085] S3, the base station determines whether it is necessary to allocate the 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.

[0086] 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.

[0087] S5, according to a preset allocation strategy, allocate reserved resources to target terminals to which reserved resources can be allocated in the preemption area, and allocate target resources to target terminals outside the preemption area; wherein the preset allocation strategy includes that a frequency band of the reserved resources does not overlap with a frequency band of the target resources.

[0088] S6: When a high-priority service appears in the network, determine whether a preemption operation is required.

[0089] 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.
