Abstract
Description
Technical Field
[0001] This application relates to the field of communication technology, and in particular to a spectrum resource allocation method, apparatus, device and storage medium. Background Technology
[0002] In the 5th-Generation (5G) mobile communication system and its subsequent evolution, mobile base station equipment is a commonly used emergency communication device. Specific forms may include emergency base station vehicles. In the event of emergencies such as floods, hurricanes, or public safety incidents, deploying mobile base station equipment can help specific users access mobile communication signals and ensure their communication experience.
[0003] Because mobile base stations and conventional base stations (non-mobile base station equipment) use the same spectrum to communicate with terminals during air interface wireless transmission, but there is no X2 interface between mobile base stations and conventional base stations, mobile base stations cannot communicate with conventional base stations.
[0004] To improve frequency utilization and increase system capacity, mobile communication systems typically employ frequency reuse technology. However, if mobile base stations and conventional base stations use the same spectrum resources and the same frequency resources, it can lead to severe co-channel interference, thereby affecting communication quality.

[0154] The accompanying drawings have illustrated specific embodiments of this disclosure, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concepts of this disclosure to those skilled in the art through reference to particular embodiments. Detailed Implementation
[0155] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0156] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to limit the invention. The singular forms "a" and "the" used in the embodiments of this application are also intended to include the plural forms, unless the context clearly indicates otherwise.
[0157] Depending on the context, the words “if” or “suppose” can be interpreted as “when”, “when”, “in response to determination”, or “in response to detection”. Similarly, depending on the context, the phrases “if determination” or “if detection (of the stated condition or event)” can be interpreted as “when determination”, “in response to determination”, “when detection (of the stated condition or event)”, or “in response to detection (of the stated condition or event)”.
[0158] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a product or system comprising a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a product or system. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the product or system that includes said element.
[0159] Mobile base station equipment is a commonly used emergency communication device. Specific forms of mobile base station equipment include emergency base station vehicles. In the event of emergencies such as floods, hurricanes, or public safety incidents, deploying mobile base station equipment can help specific users use mobile communication signals and ensure their communication experience.
[0160] Taking 5G communication systems as an example, Figure 1 The diagrams shown are of the mobile 5G equipment and conventional 5G equipment in this application. Figure 1 As shown, the mobile 5G equipment 10 typically includes a mobile base station 11 and a mobile core network 12, while the conventional 5G equipment 20 typically includes a conventional base station 21 (usually fixed in location) and a conventional core network 22. The base station and its corresponding core network can communicate via the S1 interface, and base stations of the same type can communicate via the X2 interface. Furthermore, the mobile core network 12 can communicate with the conventional core network 22.
[0161] Since the mobile 5G device 10 and the conventional 5G device 20 use the same 5G spectrum for air interface wireless transmission, but there is no X2 interface between the mobile base station 11 of the mobile 5G device 10 and the conventional base station 21 of the conventional 5G device 20, the mobile base station 11 cannot communicate with the conventional base station 21.
[0162] In 5G communication systems, frequency reuse technology is typically used to improve frequency utilization and increase system capacity. However, if the mobile base station 11 and the conventional base station 21 use the same spectrum resources and the same frequency resources, it will lead to severe co-channel interference, which will affect the communication quality of both the mobile base station 11 and the conventional base station 21.
[0163] To solve the above problems, the existing technology is to configure the spectrum resources used by the network administrators of the mobile base station 11 and the conventional base station 21 respectively, and the frequency positions of the spectrum resources configured by the two base stations are staggered to avoid co-channel interference.
[0164] However, with manual coordination, on the one hand, if one of the two types of base stations adjusts its spectrum resources, the other must also dynamically adjust accordingly; on the other hand, due to the mobile deployment characteristics of the mobile 5G equipment 10, it is necessary to ensure that the spectrum resources of all mobile base stations 11 and conventional base stations 21 within its deployment area are staggered. This results in a large workload for manual coordination, slow response time, and a high risk of errors, which is not conducive to the rapid deployment of the mobile 5G equipment 10.
[0165] The spectrum resource allocation method, apparatus, equipment, storage medium, and products provided in this application are intended to solve the above-mentioned technical problems of the prior art.
[0166] The main concept of this application is as follows: Although the mobile base station 11 cannot communicate with the conventional base station 21, the mobile core network 12 can communicate with the conventional core network 22. Therefore, when the mobile 5G equipment 10 has service needs, it can communicate with the conventional core network 22 through the mobile core network 12 to notify the conventional 5G equipment 20 to adjust the spectrum resources of the conventional base station 21. In addition, the mobile base station 11 can also determine the spectrum resources currently used by adjusting the spectrum resources, thereby ensuring that the spectrum resources used by the two base stations are different, so as to avoid co-channel interference and ensure communication quality.
[0167] It is understood that the technical solution of this application is not limited to 5G communication systems, but can also be applicable to subsequent mobile communication systems (such as 6G), and this application does not limit it.
[0168] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will be described below with reference to the accompanying drawings.
[0169] 5G communication systems introduce the concept of network slicing (NS) to address the varying network performance requirements of different communication services. Network slicing is a logical concept that involves the reorganization of resources. This reorganization selects the necessary virtual machines and physical resources for specific communication service types based on Service Level Agreements (SLAs).
[0170] Based on network slicing functionality, for service applications (such as making phone calls and accessing the internet), the core network processes slices with corresponding slice service types and slice identifiers. Network Slice Selection Assistance Information (NSSAI) includes an S-NSSAI (Single-NSSAI, used to identify a network slice) or a list of S-NSSAIs.
[0171] In the technical solution of this application, for a hybrid co-frequency networking scenario of mobile 5G equipment 10 + conventional 5G equipment 20, a first dynamic spectrum sharing method is proposed: the mobile core network 12 sends service request information to the conventional core network 22. This service request information contains a corresponding slice identifier. Based on this service request information, the conventional core network 22 allocates a specific network slice for a specific service. The specific network slice contains guaranteed reserved resources. The conventional base station 21 does not occupy the radio resources of the specific network slice for data transmission. In addition, the mobile base station 11 performs dynamic spectrum sensing and selects specific resources for uplink and downlink data transmission based on the sensing results. Furthermore, the conventional base station 21 can also perform dynamic spectrum sensing on the usage of radio resources of a specific network slice. If it finds that there is no uplink or downlink data transmission, the conventional base station 21 can use the radio resources of the specific network slice for data transmission.
[0172] Therefore, for both mobile base station 11 and conventional base station 21, wireless resources are allocated through network slicing, thereby solving the problem of co-channel interference.
[0173] Based on the first dynamic spectrum sharing method proposed in this application, the information interaction process between the devices will be explained below.
[0174] Figure 2 This is a schematic diagram of information interaction for the first dynamic spectrum sharing method in the embodiments of this application. For ease of explanation, the mobile base station 11 of the mobile 5G device 10 is defined as the first base station, the mobile core network 12 is defined as the first core network, the conventional base station 21 of the conventional 5G device 20 is defined as the second base station, and the conventional core network 22 is defined as the second core network.
[0175] It is understood that the first base station and the second base station are not limited to 5G base stations, and the first core network and the second core network are not limited to 5G core networks. The above scheme can also be applied to subsequent mobile communication systems (such as 6G). For example, the first base station and the second base station can also be 6G base stations, and the first core network and the second core network can also be 6G core networks. This application does not limit this.
[0176] like Figure 2As shown, this information interaction process mainly includes the following steps:
[0177] S101, The first core network generates service request information;
[0178] The service request information includes slice type information. When a mobile base station needs to use spectrum resources to perform a service, such as when a terminal device in a base station emergency vehicle needs to make a phone call or access the internet, the first core network generates this service request information containing slice type information.
[0179] Specifically, for different services, each network slice is uniquely identified by S-NSSAI. S-NSSAI includes Slice / Service Type (SST) information. SST is used to indicate the characteristics and service classification of the network slice, represented by 8 bits, with a value range of 0-255. Among them, the range of 0-127 is the standard SST, and the range of 128-255 is the operator-defined SST.
[0180] Standard SST values provide a method for establishing global interoperability for slices, enabling Public Land Mobile Networks (PLMNs) to provide more efficient roaming for the most frequently used slice / service types. Standard SST values are shown in Table 1 below:
[0181] Slice / Service Type SST value characteristic eMBB 1 Slicing is suitable for 5G mobile broadband enhancement URLLC 2 Slicing is suitable for high-reliability, low-latency communication. MIoT 3 Slicing is suitable for large-scale Internet of Things V2X 4 Slicing is suitable for V2X services
[0182] Table 1
[0183] S102, The first core network sends a service request message to the second core network.
[0184] The service request information is used to instruct the second core network to send a first notification message containing slice type information to the second base station. The first notification message is used to instruct the second base station to adjust the spectrum resources according to the slice type information so that the spectrum resources used by the second base station are different from those used by the first base station.
[0185] The first base station and the second base station have at least partially overlapping coverage areas. Since the two base stations have overlapping coverage areas, if they use the same frequency spectrum resources, it will lead to co-channel interference. Therefore, this embodiment adjusts the spectrum resources to ensure that the frequencies used by the two base stations are different, thereby avoiding the problem of co-channel interference.
[0186] S103. The second core network receives service request information sent by the first core network;
[0187] The service request information includes slice type information; after receiving specific service request information sent by the first core network, the second core network activates a network slice guarantee scheme for the specific service.
[0188] S104, The second core network sends the first notification message to the second base station;
[0189] The first notification message contains slice type information and is used to instruct the second base station to adjust spectrum resources according to the slice type information, so that the spectrum resources used by the second base station are different from those used by the first base station. Thus, the second core network notifies the second base station through the first notification message to enable a specific service to ensure the network slicing scheme.
[0190] S105. The first base station determines the spectrum resources used by the first base station;
[0191] For a specific slice, the second base station reserves the corresponding radio resources according to the corresponding priority. However, since network slicing can only guarantee the size of the physical resource block (PRB) occupied by the spectrum resources, and cannot correspond to the specific frequency location, the first base station determines the spectrum resources it uses based on the scheduling situation. Specifically, it can determine the spectrum resources used by the first base station through the spectrum sensing function.
[0192] S106. The first base station transmits data with the terminal equipment (UE) through the spectrum resources used by the first base station.
[0193] Since the spectrum resources used by the first base station are different from those used by the second base station, the first base station can avoid co-channel interference when transmitting data with the terminal equipment (UE) of a specific user, thus ensuring the communication quality of both the first and second base stations.
[0194] S107. The second base station receives the first notification message sent by the second core network.
[0195] The first notification message includes slice type information;
[0196] S108 and the second base station will adjust their spectrum resources.
[0197] After receiving the first notification message from the second core network, the second base station activates a specific service guarantee network slicing scheme based on the slice type information, so that the spectrum resources used by the second base station are different from those used by the first base station.
[0198] For a specific slice, the second base station reserves corresponding radio resources according to the corresponding priority. However, since network slicing only guarantees the size of the physical resource block (PRB) occupied by the spectrum resource and does not correspond to a specific frequency location, the second base station also determines the spectrum resources it uses based on the scheduling situation. Because the spectrum resources used by the first base station and the second base station are different, the second base station can avoid co-channel interference when transmitting data with the UE in the cell, thus ensuring the communication quality of both the first and second base stations.
[0199] In some embodiments, the service request information also includes slice differentiation information;
[0200] The service request information is used to instruct the second core network to send a first notification message containing slice type information and slice differentiation information to the second base station. The first notification message is used to instruct the second base station to adjust the spectrum resources according to the slice type information and slice differentiation information, so that the spectrum resources used by the first base station are the reserved physical resource blocks (PRBs) corresponding to the slice type, and the spectrum resources used by the second base station are other PRB resources besides the reserved PRBs.
[0201] Figure 3 A schematic diagram of S-NSSAI containing slice type information (SST) and slice differentiation information (SD), as shown below. Figure 3 As shown, the Slice Differentiator (SD) is used to indicate the priority of different slices within the same slice type, and is represented by 24 bits. Examples of slice differential information are shown in Table 2 below:
[0202]
[0203] Table 2
[0204] Correspondingly, the second core network sends a first notification message containing slice type information and slice differentiation information to the second base station. The first notification message is used to instruct the second base station to adjust the spectrum resources according to the slice type information and slice differentiation information, so that the spectrum resources used by the first base station are the reserved physical resource blocks (PRBs) corresponding to the slice type, and the spectrum resources used by the second base station are other PRB resources besides the reserved PRBs.
[0205] Therefore, the second core network notifies the second base station of the resource guarantee scheme for the service start of the first base station, including the number of reserved PRBs.
[0206] Correspondingly, the second base station adjusts the spectrum resources according to the slice type information and slice differentiation information, so that the spectrum resources used by the first base station are the reserved physical resource blocks (PRBs) corresponding to the slice type, and the spectrum resources used by the second base station are other PRB resources besides the reserved PRBs.
[0207] Therefore, when allocating resources, the second base station reserves a specific number of PRBs (Platform Buffers) to avoid scheduling uplink and downlink data for public network users. Based on service request information, including slice type information and slice differentiation information, the spectrum resources used by the first base station and the second base station are different. Therefore, when the first and second base stations transmit data, co-channel interference can be avoided, ensuring the communication quality of the first and second base stations.
[0208] In some embodiments, when there is service demand in the mobile base station equipment, the first base station enables spectrum sensing and interference avoidance functions to determine the spectrum resources used by the first base station.
[0209] In this embodiment, the first base station can continuously enable spectrum sensing functionality after power-on. Furthermore, after the first core network sends a service request to the second core network, the second core network can send a request confirmation message back to the first core network. The first core network then sends a confirmation message to the first base station based on the request confirmation message. Upon receiving this confirmation message, the first base station then enables spectrum sensing functionality. This embodiment does not limit the timing at which the first base station enables spectrum sensing and interference avoidance functions.
[0210] Specifically, the first base station can measure and count downlink signals within the total bandwidth of the communication system to determine whether there are specific frequency resources that meet the conditions for data transmission, thereby determining the spectrum resources used by the first base station.
[0211] Figure 4 This is a schematic diagram illustrating the determination of the spectrum resources used by the first base station in an embodiment of this application, as shown below. Figure 4 As shown, the process includes:
[0212] S105a. The first base station measures the downlink signal within the total bandwidth of the communication system and obtains the measurement results, which include the amplitude value of the frequency domain signal.
[0213] S105b: The first base station compares the amplitude value of the frequency domain signal with a preset threshold and determines that the spectrum resources with an amplitude value less than the preset threshold are available spectrum resources.
[0214] S105c: The first base station determines whether the available spectrum resources are greater than the reserved PRB resources. The reserved PRB resources are the PRB resources corresponding to the current slice type of the first base station.
[0215] S105d. If the available spectrum resources are greater than the reserved PRB resources, the first base station determines the spectrum resource with the smallest amplitude value among the available spectrum resources as the spectrum resource used by the first base station.
[0216] S105e. If the available spectrum resources are less than or equal to the reserved PRB resources, the first base station determines that the available spectrum resources are the spectrum resources used by the first base station.
[0217] Specifically, the first base station measures the downlink signal across the entire bandwidth. After receiving the time-domain signal, it performs an inverse fast fourier transform (IFFT) to transform it to the frequency domain and then calculates the amplitude value of the frequency domain signal.
[0218] The first base station processes data in downlink time slots. It performs IFFT transformation on the 14 Orthogonal Frequency Division Multiplexing (OFDM) symbols within a time slot to transform them into the frequency domain. After deducting the number of symbols occupied by the Physical Downlink Control Channel (PDCCH), the frequency domain data of the remaining symbols is calculated in units of PRBs (Physical Resource Blocks). During the calculation, the OFDM symbols occupied by each time slot are averaged, and then averaged in the frequency domain.
[0219] After obtaining the amplitude value of the frequency domain signal, the first base station compares the amplitude value of the frequency domain signal with a preset threshold, and determines that the spectrum resources with amplitude values less than the preset threshold are available spectrum resources, and determines that the spectrum resources with amplitude values greater than the preset threshold are unavailable spectrum resources.
[0220] After determining the available spectrum resources, the first base station further determines whether the size of the available spectrum resources is greater than the size of the reserved PRB resources. If it is greater, the spectrum resource with the smallest amplitude value among the available spectrum resources is determined to be the spectrum resource used by the first base station; if it is less than or equal to, the available spectrum resource is determined to be the spectrum resource used by the first base station.
[0221] After determining the spectrum resources used by the first base station, the first base station receives data signals in the downlink time slot according to the configured period and performs the above-mentioned measurement and interference avoidance process.
[0222] In some embodiments, for the second base station, after enabling the network slicing scheme for specific services, the signal is measured in the downlink time slot according to the configured time and period. If it is determined that the first base station is transmitting data using the reserved PRB resources corresponding to the slice type, the second base station continues to enable the network slicing scheme for specific services, that is, the second base station does not use the reserved PRB resources for uplink and downlink data transmission to public network users. If the second base station determines that the first base station is not transmitting data using the reserved PRB resources corresponding to the slice type, the second base station can use the reserved PRB resources for uplink and downlink data transmission to public network users.
[0223] Specifically, the second base station adjusts spectrum resources based on slice type information and slice differentiation information, including:
[0224] The downlink signal is measured within the total bandwidth of the communication system, and the measurement results are obtained, including the amplitude value of the frequency domain signal.
[0225] The amplitude value of the frequency domain signal is compared with a preset threshold, and the spectrum resources with amplitude values less than the preset threshold are determined as usable spectrum resources.
[0226] Determine whether the available spectrum resources are greater than the reserved PRB resources. The reserved PRB resources are the PRB resources corresponding to the current slice type of the first base station.
[0227] If the available spectrum resources are greater than the reserved PRB resources, then the spectrum resource with the smallest amplitude value among the available spectrum resources is determined as the spectrum resource used by the second base station.
[0228] If the available spectrum resources are less than or equal to the reserved PRB resources, then the available spectrum resources are determined to be the spectrum resources used by the second base station.
[0229] In this embodiment, the second base station can measure specific downlink signals in the same way as the first base station, and spectrum sensing can be enabled. The specific limitations of the above steps can be found in the details of signal measurement performed by the first base station in the preceding embodiments, and will not be repeated here.
[0230] In some embodiments, the second base station may also perform spectrum sensing based on terminal-assisted measurement feedback.
[0231] The second base station adjusts spectrum resources based on slice type information, including: obtaining signal measurement results of reserved PRB resources fed back by UEs in the second base station cell; within a single measurement period, if the difference between the signal measurement result of the reserved PRB resources and the signal measurement results of other PRB resources is less than a preset threshold, and the number of times the difference is less than the preset threshold reaches a preset number, then the reserved PRB resources are determined to be spectrum resources used by the second base station.
[0232] Specifically, the second base station configures a measurement signal for the user equipment (UE) within the cell. The measurement signal is a Channel State Information-Reference Signal (CSI-RS), and the measured frequency domain bandwidth is the size of the PRB slice. Then, the UE performs Channel Quality Indication (CQI) measurement feedback. The second base station is configured with a period parameter T and a count threshold N. The second base station performs frequency domain amplitude measurements of specific PRB resources in the downlink time slot according to the period parameter T, or receives CQI information fed back by the UE.
[0233] The counter is initially set to 0. If the frequency domain amplitude measurement of the PRB resource is not greater than a preset threshold, the counter is incremented by 1; if the frequency domain amplitude measurement of the PRB resource is greater than the preset threshold, the counter is reset to 0. Alternatively, the counter is initially set to 0. If the difference between the CQI information of the reserved PRB resource reported by the UE and the CQI on other PRB resources is not greater than a preset threshold, the counter is incremented by 1; if the difference between the CQI information of the reserved PRB resource reported by the UE and the CQI on other PRB resources is greater than the preset threshold, the counter is reset to 0. When the counter exceeds the parameter value N, the base station can use specific reserved PRB resources for data transmission to public network users.
[0234] The second base station continuously performs measurements according to the periodic parameter T. If the detected value is greater than the preset threshold, the counter is reset to 0, and the specific reserved PRB resources are no longer used for data transmission to public network users.
[0235] In some embodiments, reference Figure 2 After the service of the mobile base station equipment (i.e., the first base station) ends, the method also includes:
[0236] S109. The first core network sends a service cancellation message to the second core network. The service cancellation message is used to instruct the second core network to send a second notification message to the second base station. The second notification message is used to instruct the second base station to stop spectrum resource adjustment.
[0237] S110, the second core network receives service cancellation information sent by the first core network;
[0238] S111. The second core network sends a second notification message to the second base station based on the service cancellation information. The second notification message is used to instruct the second base station to stop adjusting spectrum resources.
[0239] S112, The second base station receives the second notification message sent by the second core network;
[0240] S113. The second base station stops adjusting spectrum resources according to the second notification message.
[0241] Specifically, after a specific user and service ends, the first core network sends a service cancellation message to the second core network. Upon receiving the service cancellation message, the second core network notifies the second base station to cancel the scheme of guaranteeing network slicing for the specific service, and also cancels the restrictions on scheduling resources and spectrum awareness functions.
[0242] The first dynamic spectrum sharing method provided in the above embodiments of this application allows base station equipment to autonomously resolve co-channel interference issues in scenarios where mobile communication systems operate on the same frequency, avoiding various problems caused by manually coordinating base station configurations. When deploying mobile base station equipment, no manual intervention in network adjustments is required, which helps to accelerate the response of mobile base station equipment and facilitates its rapid deployment.
[0243] In some embodiments, based on the first dynamic spectrum sharing method described above, a second dynamic spectrum sharing method is further proposed. In the second method, specific frequency location information, i.e., the frequency domain resource location information that a specific slice is expected to occupy, can be added to the slice information. Thus, the first base station and the second base station can schedule and transmit uplink and downlink data according to the agreed frequency information and a specific strategy, which can also solve the problem of co-channel interference. At the same time, it can also save the process of spectrum sensing for the first base station and the second base station, save the deployment process of mobile base station equipment, and improve deployment efficiency.
[0244] Figure 5 This is a schematic diagram of information interaction for the second dynamic spectrum sharing method in the embodiments of this application, such as... Figure 5 As shown, this information interaction process mainly includes the following steps:
[0245] S201. The first core network generates service request information, which includes slice type information, slice differentiation information, and target frequency domain PRB information corresponding to the first base station.
[0246] Optionally, the target frequency domain PRB information to be occupied by the slice can be carried in the slice differentiation information. For example, the slice differentiation information can be divided into two parts: the first part is used to indicate priority information, and the second part is used to indicate target frequency domain PRB information.
[0247] Optionally, the target frequency domain PRB information can be independent of the slice type information and slice distinction information. That is, based on the existing S-NSSAI, a frequency indicator field (FI) is added, which is used to indicate the target frequency domain PRB information.
[0248] In some embodiments, for a scheme that adds a frequency indication domain, the target frequency domain PRB information includes first indication information, which is used to indicate the location of the spectrum resources used by the first base station in the total bandwidth of the communication system.
[0249] Specifically, the first indication information can be frequency indication information, and the number of bits in the first indication information can be selected according to the actual situation. For n-bit first indication information, the total bandwidth of the communication system can be divided into 2^n equal parts, and then the specific part of the frequency resources to be used can be determined based on the specific value of the first indication information.
[0250] For example, if the first indication information is 1 bit, the total bandwidth of the communication system can be divided into two equal parts with the midpoint as the boundary, and "0" and "1" can be used to indicate which part of the bandwidth resources are used. For example, if the first indication information is "0", it means that the lower frequency half of the resources (i.e., from the lowest point to the midpoint) is used, and if the first indication information is "1", it means that the higher frequency half of the resources (i.e., from the midpoint to the highest point) is used.
[0251] For example, if the first indication information is 2 bits, the total bandwidth of the communication system can be divided into four equal parts, with the 1 / 4 point, the midpoint, and the 3 / 4 point as boundaries. The "00", "01", "10", and "11" indicate which part of the bandwidth resources to use. For instance, if the first indication information is "01", it means using the portion of resources from the 1 / 4 point to the midpoint; if the first indication information is "10", it means using the portion of resources from the midpoint to the 3 / 4 point.
[0252] Therefore, by directly indicating the location information of the frequency domain resources that a specific slice is expected to occupy through the first indication information, the first base station and the second base station can schedule and transmit uplink and downlink data according to the agreed frequency information and a specific strategy, which can also solve the problem of co-channel interference. At the same time, it can also save the first base station and the second base station from the process of spectrum sensing, reduce the deployment process of mobile base station equipment, and improve deployment efficiency.
[0253] In some embodiments, for a scheme that adds a frequency indication domain, the target frequency domain PRB information includes second indication information, which is used to indicate the PRB block location corresponding to the spectrum resources used by the first base station.
[0254] Specifically, a PRB slice parameter slice_RBG can be introduced. This parameter can be used to indicate the number of PRBs that are grouped from the total number of PRB resources. Thus, after the total PRB resources are grouped, the second indication information can be used to indicate the corresponding PRB location.
[0255] For example, if the total number of PRB resources is 100, the value of slice_RBG can be configured as {10, 20, 25, 50}, etc. Correspondingly, according to the frequency from low to high (or from high to low), the PRB resources are divided into 10 groups, 5 groups, 4 groups, 2 groups, etc. The second instruction information can specifically indicate which group of PRB resources to use.
[0256] For example, if slice_RBG is 25, then the total 100 PRB resources are divided into 4 groups, and the value of the second indication information can be any value in {1, 2, 3, 4}. If the value of the second indication information is 3, it means that the first base station is specifying the use of the third group of PRB resources.
[0257] Therefore, by directly indicating the location information of the frequency domain resources that a specific slice is expected to occupy through the second indication information, the first base station and the second base station can schedule and transmit uplink and downlink data according to the agreed frequency information and a specific strategy, which can also solve the problem of co-channel interference. At the same time, it can also save the first base station and the second base station from the process of spectrum sensing, save the deployment process of mobile base station equipment, and improve deployment efficiency.
[0258] refer to Figure 5 The methods also include:
[0259] S202, The first core network sends a service request message to the second core network;
[0260] The service request information is used to instruct the second core network to send a first notification message to the second base station, which includes slice type information, slice differentiation information and target frequency domain PRB information. The first notification message is used to instruct the second base station to adjust the spectrum resources according to the target frequency domain PRB information, so that the spectrum resources used by the first base station are the target PRB resources corresponding to the target frequency domain PRB information, and the spectrum resources used by the second base station are other PRB resources besides the target PRB resources.
[0261] S203. The second core network receives service request information sent by the first core network. The service request information includes slice type information, slice differentiation information, and target frequency domain PRB information.
[0262] S204. The second core network sends a first notification message to the second base station, which includes slice type information, slice differentiation information and target frequency domain PRB information. The first notification message is used to instruct the second base station to adjust the spectrum resources according to the target frequency domain PRB information, so that the spectrum resources used by the first base station are the target PRB resources corresponding to the target frequency domain PRB information, and the spectrum resources used by the second base station are other PRB resources besides the target PRB resources.
[0263] S205. The first base station obtains the target frequency domain PRB information corresponding to the first base station; and determines that the spectrum resource corresponding to the target frequency domain PRB information is the spectrum resource used by the first base station.
[0264] S206. The first base station transmits data with the UE using the spectrum resources used by the first base station;
[0265] S207. The second base station receives a first notification message sent by the second core network. The first notification message includes slice type information, slice differentiation information, and target frequency domain PRB information.
[0266] S208. The second base station adjusts the spectrum resources according to the target frequency domain PRB information so that the spectrum resources used by the first base station are the target PRB resources corresponding to the target frequency domain PRB information, and the spectrum resources used by the second base station are other PRB resources besides the target PRB resources.
[0267] Specifically, upon receiving a specific service request, the second core network initiates a network slicing scheme to guarantee that specific service. When scheduling public network users based on the frequency domain location corresponding to the network slice identifier, the second base station does not use the frequency domain location corresponding to the network slice identifier. The first base station uses specific network slice resources to transmit data information for specific users. The first base station schedules uplink and downlink data for specific users based on the frequency domain location corresponding to the network slice identifier.
[0268] After the service of the mobile base station equipment ends, the method also includes:
[0269] S209. The first core network sends a service cancellation message to the second core network. The service cancellation message is used to instruct the second core network to send a second notification message to the second base station. The second notification message is used to instruct the second base station to stop spectrum resource adjustment.
[0270] S210, The second core network receives service cancellation information sent by the first core network;
[0271] S211. The second core network sends a second notification message to the second base station based on the service cancellation information. The second notification message is used to instruct the second base station to stop adjusting spectrum resources.
[0272] S212, The second base station receives the second notification message sent by the second core network;
[0273] S213. The second base station stops adjusting spectrum resources according to the second notification message.
[0274] Specifically, after a specific user and service ends, the first core network sends a service cancellation message to the second core network. Upon receiving the service cancellation message, the second core network notifies the second base station to cancel the scheme of guaranteeing network slicing for the specific service, and also cancels the restrictions on scheduling resources and spectrum awareness functions.
[0275] The second dynamic spectrum sharing method provided in the above embodiments of this application involves adding target frequency information corresponding to the slice to the slice identifier. This allows the first and second base stations to directly associate the slice with specific frequency information. Consequently, dynamic spectrum sensing is no longer required between the first and second base stations, accelerating the response of mobile equipment and facilitating rapid deployment of mobile base station equipment.
[0276] It should be understood that although the steps in the flowcharts of the above embodiments are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some of the steps in the figures may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily completed at the same time, but can be executed at different times, and their execution order is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the sub-steps or stages of other steps.
[0277] In some embodiments, a core network device is provided, which may specifically be a first core network (i.e., the mobile core network of a mobile base station device).
[0278] Figure 6 This is a schematic diagram of the core network equipment in the embodiments of this application, such as... Figure 6 As shown, the core network equipment includes a memory 101, a transceiver 102, and a processor 103.
[0279] The system includes a memory for storing computer programs, a transceiver for sending and receiving data under the control of the processor, and a processor for reading the computer programs from the memory and performing the following operations:
[0280] Generate business request information, which includes slice type information;
