[0060] 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.

[0061] The method for quickly changing and switching channel resources provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown. Among them, the industrial automation equipment 102 communicates with the control terminal 101 through a wireless network. The control terminal 101 configures high-speed communication signaling based on rapid change and switching of channel resources according to the business requirements of the industrial automation equipment; wherein the high-speed communication signaling based on rapid change and switching of channel resources is used to indicate at least one operation of allocating, changing, and switching channel resources; the channel resources include: main carrier resources, service carrier resources, and reserved carrier resources; when it is necessary to rapidly change and switch channel resources, the channel resources are changed and switched according to the instructions in the high-speed communication signaling based on rapid change and switching of channel resources. Among them, the industrial automation equipment 102 can be, but is not limited to, various personal computers, laptops, smart phones, tablet computers, Internet of Things devices, etc. The control terminal 101 can be a gNB (5G base station).

[0062] In an exemplary embodiment, Figure 2 As shown, a method for quickly changing and switching channel resources is provided, and the method is applied to Figure 1 The control end in FIG. 1 is taken as an example to illustrate, and the method includes the following steps 201 to 202. Among them:

[0063] Step 201 : configuring high-speed communication signaling based on rapid change and switching of channel resources according to the business requirements of industrial automation equipment.

[0064] In the industrial automation application environment, the interference types and intensities of different industrial application devices and sensors on the communication system are unpredictable and random. The industrial automation test information carried by the uplink (UL) and downlink (DL) is different, and the changes in test items cause load imbalance caused by changes in network load, which can easily cause radio link failure (RLF, Radio Link Failure). When the equipment, sensors, etc. carried by industrial automation equipment change, or the test items change, when the communication system on the industrial automation equipment uses a carrier aggregation system, if the existing control channel signaling is used to change the main carrier resources, it will cause the network to have a hard switching problem caused by the change of the main carrier resources.

[0065] In view of the above problems, the control end configures high-speed communication signaling based on rapid change and switching of channel resources according to the business requirements of industrial automation equipment. Thus, the rapid change and switching of channel resources can be completed through the instructions of high-speed communication signaling based on rapid change and switching of channel resources.

[0066] Among them, the high-speed communication signaling based on rapid change and switching of channel resources is used to indicate at least one operation of allocating, changing, and switching channel resources; the channel resources include: main carrier resources, service carrier resources, and reserved carrier resources.

[0067] Optionally, the primary carrier resource is used to carry signaling for communication in carrier aggregation mode, a service list on industrial automation equipment, and a rapid change and switching threshold on service carrier resources;

[0068] Optionally, the service carrier resource is used to carry the payload of different applications on the industrial automation equipment. In addition, the service carrier resource can also be controlled through the service carrier resource control field corresponding to each payload. When the signaling carried on the main carrier causes the interference type and / or interference level to change due to the change in the application environment of the industrial automation equipment, resulting in a large number of errors and / or retransmissions in the interaction of control signaling, the main carrier activates the service carrier resource control field corresponding to each payload to assist in sending control signaling, so as to minimize the number of errors and retransmissions of control signaling, thereby significantly reducing the resources occupied by control signaling, thereby significantly improving the payload and throughput.

[0069] Optionally, the reserved carrier resource is used as a backup resource for the service carrier resource, and is used to simultaneously send the effective load carried by the service carrier resource before the channel resource is quickly changed and switched, thereby avoiding the communication interruption problem caused by hard switching of channel resources during high-speed communication.

[0070] For example, Figure 3As shown, a composition structure of a high-speed communication signaling based on rapid change and switching of channel resources is shown. The high-speed communication signaling based on rapid change and switching of channel resources is divided into several functional fields according to functions, and the functional fields include: an automation equipment service carrier switching threshold setting field, an automation equipment service carrier type allocation field, an automation equipment service carrier channel resource rapid change and switching enable field, an automation equipment reserved resource enable field, an automation equipment channel resource measurement field, an automation equipment channel resource rapid change and switching strategy selection field, and at least one of an automation equipment channel resource rapid change and switching high-speed communication feedback field.

[0071] It should be noted that this embodiment provides a possible configuration example of high-speed communication signaling based on rapid change and switching of channel resources. In actual application, it can also be divided into different fields (for example, different names and numbers of fields) as needed, and the function of each field is defined. During program operation, the definition of field names does not affect the actual functions performed.

[0072] The automation equipment service carrier switching threshold setting field is used to set different channel resource rapid change and switching thresholds for different service requirements on the automation equipment.

[0073] Exemplarily, the control end sets different channel resource rapid change and switching thresholds for different services on industrial automation equipment to meet different requirements for interference, bit error rate, number of retransmissions, real-time performance, etc. through the automation equipment service carrier switching threshold setting field. When the preset threshold is reached, the control end initiates high-speed communication based on rapid change and switching of channel resources. By setting the threshold, the number of rapid changes and switching of channel resources in the communication system on the automation equipment can be significantly reduced, thereby reducing the number of signaling interactions and significantly improving the throughput of the payload.

[0074] It should be noted that different thresholds can be set for different carrier resources and service requirements, such as control signaling transmission, service data transmission, etc. Among them, the preset threshold can be dynamically adjusted according to the actual requirements and measurement values ​​on the automation equipment to adapt to different working environments, channel qualities and communication requirements.

[0075] The automation equipment service carrier type allocation field is used to divide the component carriers of the automation equipment into different types.

[0076] Exemplarily, the control end divides all component carriers into different types according to the interference type, interference intensity, uplink (UL) and / or downlink (DL) component carrier payload size, user end (UE) uplink (UL) and / or downlink (DL) component carrier resource duplex mode, signaling interaction overhead, etc. (not limited to these) in different working areas of the industrial automation equipment through the automation equipment service carrier type allocation field.

[0077] Exemplarily, the service carrier types may be divided into: communication stability type, parameter change type, and service support type, and different service carrier types correspond to different service scenarios.

[0078] Exemplarily, for stable communication, its characteristics include: 1) the interference type and / or interference intensity is kept within a preset range, and the interference is controllable; 2) high data throughput and data rate are not required; 3) it is usually used for carrying and interacting communication signaling on automation equipment.

[0079] Exemplarily, for the parameter change type, its features include: 1) the bit error rate, channel resource multiplexing mode, duplex mode, etc. on the carrier resources can be flexibly and conveniently adjusted; 2) after the parameters are changed, it can adapt to different service types and requirements; 3) it is usually used for the allocation of service carrier resources and / or the allocation of reserved carrier resources.

[0080] Exemplarily, for the service support type, its characteristics include: 1) classifying carrier resources according to the bit error rate, channel resource multiplexing mode, duplex mode, etc. required by the service; 2) allocating carrier resources to different services in their respective categories; 3) minimizing resource allocation signaling interactions; 4) when reallocating / releasing, usually reallocating / releasing as a whole according to classification standards such as bit error rate, channel resource multiplexing mode, duplex mode, etc., to avoid carrier resource fragmentation; 5) usually used for the allocation of service carrier resources.

[0081] The automation equipment service carrier channel resource rapid change and switching enable field is used to enable or disable rapid change and switching of service carrier channel resources.

[0082] It should be noted that when the rapid change and switching of service carrier channel resources are disabled, all other fields can be disabled based on the high-speed communication signaling for the rapid change and switching of channel resources, thereby reducing the signaling load.

[0083] The automation equipment reserved resource enable field is used to enable or disable reserved carrier resources.

[0084] The automation equipment channel resource measurement field is used to enable or disable the main carrier resource and complete the measurement of the service carrier resource and the reserved carrier resource. The measured data includes: interference type / interference intensity, bit error rate, channel resource multiplexing mode, duplex mode, etc. (not limited to this).

[0085] It should be noted that different business requirements correspond to different measurement requirements. For example, for carrier resources that carry signaling, only the interference type / interference intensity needs to be measured; interference-sensitive services only need to measure the interference type / interference intensity; services with high bit error rate requirements only need to measure the bit error rate; and service types with high carrier resource requirements need to measure the channel resource multiplexing mode and duplex mode in order to dynamically adjust the working mode of the carrier resources.

[0086] The automation equipment channel resource rapid change and switching strategy selection field is used to set different strategies according to the change and switching conditions initiated by the rapid change and switching of the main carrier resources, service carrier resources, and reserved carrier resources.

[0087] Exemplarily, the channel resource rapid change and switching strategy may include: any one of a signaling retention strategy, a service support strategy, a performance improvement strategy, an auxiliary transmission strategy, a resource supplement strategy, and a fragmentation integration strategy. Optionally, the signaling retention strategy includes: changing the multiplexing mode on the signaling carrier resources, and / or the control commands carried by part of the main carrier by the service carrier; the service support strategy includes: changing the data rate and / or transmission mode on the existing carrier resources according to the measurement data of the carrier resources on different service types; the performance improvement strategy includes: adjusting the service carrier resource allocation based on the service and / or measurement requirements, and adjusting the data rate and / or transmission mode on the existing service carrier resources; the auxiliary sending strategy includes: sending and measuring all the information carried on the signaling on the main carrier resources on the service carrier resources and / or reserved carrier resources, and selecting carrier resources to assist in sending signaling based on at least one influencing factor of interference type, interference intensity, and bit error rate; the resource supplement strategy includes: cutting carrier resources and changing the transmission mode on the existing carrier resources; the fragment integration strategy includes: replacing partially fragmented and / or fully fragmented carrier resources, and integrating the fragmented carrier resources into continuous and complete carrier resources for scheduling and allocation.

[0088] Among them, the signaling retention strategy includes: using time multiplexing, space multiplexing, frequency multiplexing and other methods, as well as using the service carrier to carry part of the control commands carried by the main carrier, and sending them using time multiplexing and other methods, so as to increase the transmission efficiency and complete the rapid change and switching of the main carrier resources. This strategy can ensure the stability of the control signaling sent by the main carrier and avoid the retransmission problem caused by the unstable control signaling. Exemplarily, the control end sets the main carrier resource selection threshold. When the selection threshold is exceeded, the control end changes the multiplexing method on the signaling carrier resource; at the same time, the interference of the service carrier resource, the wireless link connection status, etc. are measured, and compared with the selection threshold; if the selection threshold is exceeded, the control end adds the same resource as the worst auxiliary carrier resource as a temporary main carrier resource, and releases the service carrier resource.

[0089] Among them, the service support strategy includes: using fewer interference types, lower interference intensity, lower data rate, stable duplex mode, etc. for transmission. Therefore, the effectiveness of all services on industrial automation equipment can be supported with the most stable communication parameter set. Exemplarily, the control end measures the carrier resource interference, bit error rate, number of retransmissions, etc. on different service types. If the measured value exceeds the preset threshold, the control end changes the data rate, duplex mode, multiplexing mode, etc. on the existing carrier resources, so that the service can be maintained in the most stable way.

[0090] Among them, the performance improvement strategy includes: the control end adjusts the service carrier resource allocation based on the service and / or measurement requirements, the multiplexing mode, duplex mode, data rate, etc. on the existing service carrier resources to adjust the performance of the service and / or measurement requirements. When the service and / or measurement requirements on the industrial automation equipment change, the throughput and payload requirements on the communication link will also change; at this time, the control end can adjust the resources on the current service to adapt to the new service and / or measurement requirements. Exemplarily, the control end adjusts the multiplexing mode, duplex mode, data rate, etc. on the existing service carrier resources to meet the service and / or measurement requirements; if the performance parameters on the existing service carrier resources cannot meet the energy and / or measurement requirements, the control end initiates a service carrier resource rapid change and switching request through a temporary service carrier resource, and the control end receives the request and supplements additional resources that are the same as the main carrier resources as the new main carrier resources of the base station (BS), and releases the same number of carrier resources from the service carrier resources to make the occupied service carrier resources equivalent to the original ones.

[0091] Among them, the auxiliary transmission strategy includes: the control end sends and measures all the information carried on the signaling on the main carrier resources on the service carrier resources and / or reserved carrier resources, and selects the carrier resources with the lowest interference type and / or interference intensity and bit error rate to assist in sending signaling. Thereby, the robustness of signaling on the main carrier resources can be enhanced. Exemplarily, the control end allocates service carrier resources and / or reserved carrier resources to send all the information sent by signaling on the existing main carrier resources, and measures the interference type and / or interference intensity, bit error rate and other information, selects service carrier resources and / or reserved carrier resources that do not exceed the preset threshold to assist the main carrier resources in sending signaling, and releases the service data carried on the existing service carrier resources and / or reserved carrier resources.

[0092] Among them, resource supplement strategies include: using carrier resource cutting, changing the multiplexing mode on existing carrier resources, changing the duplex mode, etc. to improve carrier resource utilization. When the signaling information carried on the main carrier changes and the service resources carried on the service carrier resources are insufficient, additional resources can be supplemented by the multiplexing mode and / or duplex mode on the reserved carrier resources. Exemplarily, if the main carrier, service carrier, and reserved carrier resources are insufficient, the control end can change the multiplexing mode and duplex mode on the existing carrier resources to improve carrier resource utilization. If the requirements are still not met, the control end can allocate new carrier resources as new main carriers, service carriers, and reserved carrier resources. At the same time, release the main carrier, service carrier, and reserved carrier resources to keep the total number of carrier resources used for signaling and / or services controlled or unchanged.

[0093] Among them, the fragment integration strategy includes integrating the fragmented carrier resources into continuous and complete carrier resources by replacing part and / or all of the fragmented carrier resources, so as to facilitate the scheduling and allocation of the control end. When the communication adjustment based on the rapid change and switching of channel resources is implemented on the industrial automation equipment, after the frequent allocation and release of the main carrier, service carrier, and reserved carrier resources, there will be a large number of fragmented carrier resources distributed in different areas on all carrier resources, which increases the scheduling complexity and difficulty of the carrier resources on the control end. At this time, the control end records the position and size of the fragmented carrier resources and calculates the size of the total fragmented carrier resources; matches the size of the fragmented carrier resources on the main carrier, service carrier, and reserved carrier resources that are adjacent to the fragmented carrier resource position; after the matching is completed, the control end initiates a rapid change and switching request for the main carrier resources on the fragmented carrier resources, completes the allocation of fragmented carrier resources, and releases the existing carrier resources to form a new complete carrier resource.

[0094] The high-speed communication feedback field for rapid change and switching of automation equipment channel resources is used to implement signaling interaction and signaling feedback for rapid change and switching of automation equipment channel resources.

[0095] For example, Figure 4 As shown, step 201 may include the following steps:

[0096] Step 2011, respectively initialize various functional fields in the high-speed communication signaling based on rapid change and switching of channel resources.

[0097] Exemplarily, the control end respectively initializes at least one functional field in the automation equipment service carrier switching threshold setting field, the automation equipment service carrier type allocation field, the automation equipment service carrier channel resource rapid change and switching enable field, the automation equipment channel resource measurement field, the automation equipment channel resource rapid change and switching strategy selection field, and the automation equipment channel resource rapid change and switching high-speed communication feedback field in the high-speed communication signaling based on the rapid change and switching of channel resources.

[0098] Step 2012: Initiate a communication adjustment request based on rapid change and switching of channel resources.

[0099] In this embodiment, the control end initiates a communication adjustment request based on rapid change and switching of channel resources. For example, the control end initiates a service carrier resource rapid change and switching request through a temporary service carrier resource, and the control end receives the request and supplements additional resources that are the same as the main carrier resource as the new main carrier resource of the base station, and releases the same number of carrier resources from the service carrier resource.

[0100] Step 2013: according to the service requirements of the industrial automation equipment, the automation equipment channel resource rapid change and switching strategy selection field in the high-speed communication signaling based on the channel resource rapid change and switching is changed.

[0101] In this embodiment, the interference type, interference intensity, and industrial automation test information sent on the uplink and / or downlink on the communication system of the industrial automation equipment can be changed through pre-set change and switching strategies. When the test item changes, the automation equipment channel resource rapid change and switching strategy selection field in the high-speed communication signaling based on rapid change and switching of channel resources is changed.

[0102] Step 202: When it is necessary to quickly change and switch the channel resources, change and switch the channel resources according to the instructions in the high-speed communication signaling based on the fast change and switch of the channel resources.

[0103] In this embodiment, the initiation of high-speed communication signaling based on rapid change and switching of channel resources is all based on the carrier resources currently occupied by the control end, without the need to use additional signaling and resources, thereby significantly reducing the overhead of the communication system.

[0104] Exemplarily, the transmission of the payload on the existing service carrier resources is disconnected, the payload is sent and received only on the reserved carrier resources, and new service carrier resources are reallocated for the service types that need to be quickly changed and switched.

[0105] In the above-mentioned method for rapid change and switching of channel resources, high-speed communication signaling based on rapid change and switching of channel resources is configured according to the business requirements of industrial automation equipment; thus, rapid change and switching of channel resources can be initiated on the currently occupied carrier resources through the base station without using additional signaling and resources, thereby reducing the overhead of the communication system. When rapid change and switching of channel resources is required, the channel resources are changed and switched according to the instructions in the high-speed communication signaling based on rapid change and switching of channel resources. Thus, different strategies can be set for the change and switching conditions initiated by different main carrier resource rapid change and switching triggers, effectively reducing the overhead of the communication system and the probability of wireless link failure while ensuring that the system communication is not interrupted, thereby significantly improving the throughput of the communication system.

[0106] In an exemplary embodiment, Figure 5 As shown, another method for quickly changing and switching channel resources is provided, and this method is applied to Figure 1 The control end in FIG. 1 is taken as an example to illustrate, and the following steps 501 to 506 are included. Among them:

[0107] Step 501 : According to the business requirements of the industrial automation equipment, high-speed communication signaling based on rapid change and switching of channel resources is configured.

[0108] Step 502: When it is necessary to quickly change and switch the channel resources, change and switch the channel resources according to the instructions in the high-speed communication signaling based on the fast change and switch of the channel resources.

[0109] For the specific implementation process and technical effects of steps 501 to 502 in this embodiment, please refer to Figure 2 The descriptions of steps 201 to 202 in the method are not repeated here.

[0110] Step 503: Send the service payload on the reserved carrier resources and the reallocated new service carrier resources simultaneously, and measure the interference, bit error rate and number of retransmissions on the reserved carrier resources and the new service carrier resources simultaneously.

[0111] In this embodiment, when the carrier resources are rapidly changed and switched, the control end disconnects the transmission of the payload on the existing service carrier, and only transmits and receives the payload on the reserved carrier resources. At the same time, the control end reallocates new service carrier resources for the service types that need to be rapidly changed and switched. After the carrier resources are rapidly changed and switched, the service payload is simultaneously transmitted on the reallocated corresponding service carrier resources and the reserved carrier resources, and the interference, bit error rate, and number of retransmissions on the two resources are simultaneously measured.

[0112] It should be understood that when the control end measures the interference on the reserved carrier resources and the new service carrier resources, the network architecture of the base station and the terminal can be used for reference. Exemplarily, the various types of interference generated within the cell / between cells, cell edges, etc. determined by the base station include but are not limited to: inter-subband cross-link interference between base stations, inter-subband cross-link interference between terminals within the cell, inter-subband cross-link interference between terminals between cells, interference from the final terminal between cells to base stations of other adjacent cells, interference from base stations between cells to terminals of adjacent cells, etc.

[0113] For example, Figure 6 As shown, a schematic diagram of a network architecture for rapid change and switching of channel resources is provided, which can be applied to the network architecture of a terminal (UE) and a base station (gNB). In this network architecture, it is applicable to the above Figure 2 The method of rapid change and switching of channel resources is shown. Among them, interference type 1: Inter-subband cross-link interference (CLI) between gNBs refers to the interference of the gNB receiver from another gNB transmitter. Interference type 2: Inter-subband cross-link interference (CLI) between UEs in a cell refers to the impact of UE transmission on non-overlapping resources in the same cell on another UE. Interference type 3: Inter-subband cross-link interference (CLI) between UEs in an inter-cell refers to the impact of UE transmission on non-overlapping resources in an adjacent cell on another UE. Interference type 4: Inter-cell UE interference to gNBs in other adjacent cells refers to the interference of UE transmission in one cell to the uplink (UL) reception of gNBs in other cells. Interference type 5: Inter-cell gNB interference to UEs in adjacent cells refers to the downlink (DL) reception interference of gNBs in one cell to UEs in other cells. Interference type 6: New strong inter-cell interference caused by cell identity conflict means that when there is a cell identity conflict, the UE at the cell edge is subject to strong inter-cell interference caused by the gNB with the same identity in the adjacent cell; due to the cell identity conflict, multiple gNBs use different interference suppression methods for the same UE at different locations in different cells, resulting in the UE being subject to different types of strong interference at the same time.

[0114] Step 504: compare the measured values ​​of the reserved carrier resources and the new service carrier resources with a preset threshold.

[0115] In this embodiment, when the rapid change and switching of the carrier resources ends, the control end compares the measured values ​​on the two resources (the reserved carrier resources and the new service carrier resources) with the preset threshold.

[0116] Step 505: If the measured value is less than a preset threshold, the transmission and / or reception of the reserved carrier resources is disconnected to release the reserved carrier resources.

[0117] Step 506: If the measured value is greater than a preset threshold, new service carrier resources are reallocated.

[0118] In this embodiment, if the measured value is less than the preset threshold, the control end disconnects the reserved carrier resource for transmission and / or reception, releases the reserved carrier resource, and completes the rapid change and switching based on the channel resource. If the measured value is greater than the preset threshold, the control end will reallocate new service carrier resources and repeat the above steps 504 to 506.

[0119] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above-mentioned embodiments can include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the steps or stages in other steps.

The implementation scheme for solving the problem provided by the device is similar to the implementation scheme recorded in the above method, so the specific limitations in the embodiments of one or more devices for quickly changing and switching channel resources provided below can refer to the limitations of the method for quickly changing and switching channel resources above, and will not be repeated here.

[0121] In an exemplary embodiment, Figure 7 As shown, a device for quickly changing and switching channel resources is provided, which is applied to a control end and includes: a configuration module 701 and a change and switch module 702, wherein:

[0122] Configuration module 701, configured to configure high-speed communication signaling based on rapid change and switching of channel resources according to the service requirements of industrial automation equipment; wherein the high-speed communication signaling based on rapid change and switching of channel resources is used to indicate at least one operation of allocating, changing, and switching channel resources; the channel resources include: main carrier resources, service carrier resources, and reserved carrier resources;

[0123] The changing and switching module 702 is used to change and switch the channel resources according to the instructions in the high-speed communication signaling based on the rapid change and switching of channel resources when rapid change and switching of channel resources is required.

[0124] Exemplarily, the high-speed communication signaling based on rapid change and switching of channel resources is divided into several functional fields according to functions, and the functional fields include: an automation equipment service carrier switching threshold setting field, an automation equipment service carrier type allocation field, an automation equipment service carrier channel resource rapid change and switching enable field, an automation equipment reserved resource enable field, an automation equipment channel resource measurement field, an automation equipment channel resource rapid change and switching strategy selection field, and at least one of the high-speed communication feedback fields for rapid change and switching of automation equipment channel resources.

[0125] Exemplarily, the automation equipment service carrier switching threshold setting field is used to set different channel resource rapid change and switching thresholds for different service requirements on the automation equipment;

[0126] The automation equipment service carrier type allocation field is used to divide the component carriers of the automation equipment into different types;

[0127] The automation equipment service carrier channel resource rapid change and switching enable field is used to enable or disable rapid change and switching of service carrier channel resources;

[0128] The automation device reserved resource enable field is used to enable or disable reserved carrier resources;

[0129] The automation equipment channel resource measurement field is used to enable or disable the main carrier resource and complete the measurement of the service carrier resource and the reserved carrier resource;

[0130] The automation equipment channel resource rapid change and switching strategy selection field is used to set different strategies according to the change and switching conditions initiated by the rapid change and switching of the main carrier resources, service carrier resources, and reserved carrier resources;

[0131] The high-speed communication feedback field for rapid change and switching of automation equipment channel resources is used to implement signaling interaction and signaling feedback for rapid change and switching of automation equipment channel resources.

[0133] The service carrier resources are used to carry the payloads of different applications on industrial automation equipment;

[0134] The reserved carrier resources serve as backup resources for the service carrier resources and are used to simultaneously send the effective load carried on the service carrier resources before the channel resources are quickly changed and switched.

[0135] Exemplarily, the configuration module 701 is specifically used to initialize each functional field in the high-speed communication signaling based on rapid change and switching of channel resources; initiate an adjustment communication request based on rapid change and switching of channel resources; and change the automation equipment channel resource rapid change and switching strategy selection field in the high-speed communication signaling based on rapid change and switching of channel resources according to the business requirements of the industrial automation equipment.

[0136] Exemplarily, the change and switching module 702 is specifically used to disconnect the payload transmission on the existing service carrier resources, send and receive the payload only on the reserved carrier resources, and reallocate new service carrier resources for the service types that need to be quickly changed and switched.

[0137] The above-mentioned device configures high-speed communication signaling based on rapid change and switching of channel resources according to the business requirements of industrial automation equipment; thus, rapid change and switching of channel resources can be initiated on the currently occupied carrier resources through the base station without using additional signaling and resources, thereby reducing the overhead of the communication system. When rapid change and switching of channel resources are required, the channel resources are changed and switched according to the instructions in the high-speed communication signaling based on rapid change and switching of channel resources. Thus, different strategies can be set for the change and switching conditions initiated by different triggers for rapid change and switching of main carrier resources, effectively reducing the overhead of the communication system and the probability of wireless link failure while ensuring that the system communication is not interrupted, thereby significantly improving the throughput of the communication system.
