Description

Technical Field

[0001] The present application relates to the field of wireless communication technology, and in particular to a communication method, a communication device, and a communication system. Background Art

[0002] Currently, new radio (NR) systems use shared channel transmission, dynamically sharing time and frequency resources between terminals. Base stations use scheduling features to allocate time and frequency resources for uplink and downlink. This not only ensures system throughput and user resource fairness, but also improves system capacity and network performance. Scheduling features include the following basic functions: priority calculation, modulation and coding scheme (MCS) selection, and resource allocation.

[0003] In traditional uplink scheduling, terminals periodically send Scheduling Requests (SRs) to request time and frequency resources. Depending on the protocol, the period for sending SRs can be quite long, for example, up to 80 milliseconds. Therefore, in the worst case, if a terminal has uplink data to send, it will have to wait a long time before sending a SR, increasing uplink latency.

[0004] There is currently no good way to reduce the latency of a terminal requesting uplink scheduled time and frequency resources. Summary of the Invention

[0005] The present application provides a communication method, a communication device, and a communication system for reducing the delay of a terminal requesting time-frequency resources for uplink scheduling, thereby improving communication efficiency.

[0006] In the first aspect, an embodiment of the present application provides a wireless communication method, which can be executed by an access network device or a module (such as a chip) applied to the access network device. The method includes: receiving a first pre-scheduling parameter set from an application function network element and a 5QI corresponding to each pre-scheduling parameter set in the first pre-scheduling parameter set; receiving a data packet of a target service from a terminal, the data packet containing a QFI; determining a first 5QI corresponding to the QFI; determining a pre-scheduling parameter set corresponding to the first 5QI from a second pre-scheduling parameter set; wherein the second pre-scheduling parameter set includes the first pre-scheduling parameter set; and pre-scheduling the uplink resources of the terminal according to the pre-scheduling parameter set corresponding to the first 5QI.

[0007] According to the above solution, since multiple pre-scheduling parameter sets are configured for the base station, the base station can pre-schedule the terminal's uplink resources based on the pre-scheduling parameter sets, thereby reducing the time it takes for the terminal to obtain uplink resources and thereby improving the terminal's communication efficiency. Furthermore, since the AF configures one or more pre-scheduling parameter sets for the base station, the pre-scheduling parameter sets can be dynamically configured or adjusted according to actual needs, facilitating the accurate allocation of corresponding resources to the terminal.

[0008] In a possible implementation method, the QFI and the QoS configuration corresponding to the QFI are received from a session management network element, where the QoS configuration includes the first 5QI; and the first 5QI is determined based on the QFI and the QoS configuration corresponding to the QFI.

[0009] According to the above solution, the base station can determine the 5QI corresponding to the QFI, thereby providing a basis for subsequent determination of the pre-scheduling parameter set.

[0010] In a possible implementation method, the second pre-scheduling parameter set also includes a default pre-scheduling parameter set.

[0011] According to the above scheme, on the one hand, a pre-scheduling parameter set can be configured for the base station, and on the other hand, the base station also has a default pre-scheduling parameter set, thereby ensuring that the base station has at least a default pre-scheduling parameter set available, which helps to pre-scheduling uplink resources for the terminal and reduce the delay in the terminal obtaining resources.

[0012] In one possible implementation method, a third pre-scheduling parameter set is received from the application function network element; based on the third pre-scheduling parameter set, a default pre-scheduling parameter set is updated to obtain a fourth pre-scheduling parameter set; wherein the second pre-scheduling parameter set also includes the fourth pre-scheduling parameter set.

[0013] According to the above solution, the base station can update the default pre-scheduling parameter set to obtain a new pre-scheduling parameter set, which helps to dynamically adjust the pre-scheduling parameter set.

[0014] In a possible implementation method, the default pre-scheduling parameter set includes a first pre-scheduling maximum number of users and a first total amount of scheduled data; any one of the pre-scheduling parameter sets in the third pre-scheduling parameter set includes a second pre-scheduling maximum number of users and a second total amount of scheduled data; the default pre-scheduling parameter set and any one of the pre-scheduling parameter sets include the same pre-scheduling minimum interval period; based on the second pre-scheduling maximum number of users and the second total amount of scheduled data, the first pre-scheduling maximum number of users and the first total amount of scheduled data in the default pre-scheduling parameter set are updated to obtain a pre-scheduling parameter set in the fourth pre-scheduling parameter set.

[0015] In a possible implementation method, a pre-scheduling parameter set includes one or more of the following information: a pre-scheduling minimum interval period, a pre-scheduling maximum number of users, and a total amount of scheduled data.

[0016] In a second aspect, an embodiment of the present application provides a wireless communication method, which can be performed by an application function network element or a module (such as a chip) applied to the application function network element. The method includes: determining a first pre-scheduling parameter set and a 5QI corresponding to each pre-scheduling parameter set in the first pre-scheduling parameter set, the first pre-scheduling parameter set including pre-scheduling parameter sets corresponding to multiple device groups respectively; and sending the first pre-scheduling parameter set and the 5QI corresponding to each pre-scheduling parameter set in the first pre-scheduling parameter set to an access network device.

[0017] According to the above solution, since multiple pre-scheduling parameter sets are configured for the base station, the base station can pre-schedule the terminal's uplink resources based on the pre-scheduling parameter sets, thereby reducing the time it takes for the terminal to obtain uplink resources and thereby improving the terminal's communication efficiency. Furthermore, since the AF configures one or more pre-scheduling parameter sets for the base station, the pre-scheduling parameter sets can be dynamically configured or adjusted according to actual needs, facilitating the accurate allocation of corresponding resources to the terminal.

[0018] In one possible implementation method, configuration information of the network is obtained, where the configuration information includes the period of service messages in the multiple devices; based on the configuration information, the multiple devices are divided into the multiple device groups; wherein each pre-scheduling parameter set in the first pre-scheduling parameter set corresponds to a period, and the multiple pre-scheduling parameter sets correspond to different periods respectively.

[0019] According to the above scheme, multiple devices can be grouped to obtain multiple device groups, and then pre-scheduling parameter sets can be obtained based on the multiple device groups. This method can accurately determine each pre-scheduling parameter set, which helps to achieve accurate pre-scheduling of resources for the terminal.

[0020] In one possible implementation method, the maximum number of pre-scheduled users in the pre-scheduling parameter set corresponding to the first device group is determined based on the number of devices in the first device group; the total amount of scheduled data in the pre-scheduling parameter set corresponding to the first device group is determined based on the total amount of data of the first device group; wherein the first device group is any one device group among the multiple device groups.

[0021] The above solution helps to accurately divide each device group.

[0022] In one possible implementation method, the 5QI corresponding to the first device group is determined based on the QoS requirement information of the first device group; wherein the first device group is any one of the multiple device groups, and the first device group corresponds to a pre-scheduling parameter set in the first pre-scheduling parameter set.

[0023] According to the above scheme, it is helpful to accurately determine the 5QI corresponding to each device group.

[0024] In one possible implementation method, the first pre-scheduling parameter set and the 5QI corresponding to each pre-scheduling parameter set in the first pre-scheduling parameter set are sent to the access network device through the 5G core network; or, the first pre-scheduling parameter set and the 5QI corresponding to each pre-scheduling parameter set in the first pre-scheduling parameter set are sent to the access network device through the network management device corresponding to the access network device.

[0025] In a possible implementation method, a default pre-scheduling parameter set is obtained; based on the first pre-scheduling parameter set, the default pre-scheduling parameter set is updated to obtain a fifth pre-scheduling parameter set; and the fifth pre-scheduling parameter set is sent to the access network device.

[0026] According to the above solution, the application function network element can dynamically adjust the default pre-scheduling parameter set, which helps to accurately determine the pre-scheduling parameter set.

[0027] In a possible implementation method, the default pre-scheduling parameter set includes a first pre-scheduling maximum number of users and a first total amount of scheduled data; any one of the pre-scheduling parameter sets in the first pre-scheduling parameter set includes a third pre-scheduling maximum number of users and a third total amount of scheduled data; the default pre-scheduling parameter set and any one of the pre-scheduling parameter sets include the same pre-scheduling minimum interval period; based on the third pre-scheduling maximum number of users and the third total amount of scheduled data, the first pre-scheduling maximum number of users and the first total amount of scheduled data in the default pre-scheduling parameter set are updated to obtain a pre-scheduling parameter set in the fifth pre-scheduling parameter set.

[0028] In a possible implementation method, a pre-scheduling parameter set includes one or more of the following information: a pre-scheduling minimum interval period, a pre-scheduling maximum number of users, and a total amount of scheduled data.

Optionally, the above-mentioned network element or function can be implemented by a single device, or by multiple devices, or can be a functional module within a single device, and this is not specifically limited in the embodiments of the present application.

[0098] The session management network element, user plane network element, policy control network element, and application function network element in this application can be the SMF, UPF, PCF, and AF in Figure 2(a) or Figure 2(b), respectively, or can be network elements having the functions of the above-mentioned SMF, UPF, PCF, and AF in future communications such as 6G networks.

[0099] The access network device in the embodiment of the present application may be a wireless access network device. For ease of explanation, in the embodiment of the present application, a base station is described as an example of an access network device.

[0100] Communication technologies in traditional industrial scenarios are usually connected via wired connections. In wired industrial field networks, the following two types of communication messages are defined in existing industrial communication protocols:

[0101] 1) Aperiodic messages: These are non-real-time messages between business servers and industrial terminals, used for configuration and maintenance, and are typically L3 messages. Industrial terminals include industrial controllers (such as programmable logic controllers (PLCs)) and industrial devices (such as input / output (I / O) devices).

[0102] 2) Periodic messages: Real-time or quasi-real-time messages strongly related to production operations, sent between PLCs or between PLCs and I / O devices, usually L2 messages. Periodic messages usually use a "periodic" bus transmission mechanism.

[0103] With the continuous development of 5G industrial Internet technology, the communication of industrial terminals in industrial field networks is currently transitioning from wired to wireless communication. Industrial terminals themselves are not within the scope of 3GPP definition, meaning they cannot communicate directly with 3GPP networks. Currently, industrial terminals generally access 3GPP networks through customer premises equipment (CPE). The CPE here can be the UE shown in Figure 2(a) or Figure 2(b), i.e., a terminal in the 3GPP network.

[0104] Figure 3 Schematic diagram of industrial terminals accessing the 5G network in the industrial field network. The 5G local area network (LAN) provides data access for a large number of industrial terminals and provides transmission services with strict quality assurance, such as latency and reliability, which must comply with industrial standards. Taking industrial terminals including PLC and I / O devices as an example, usually, one CPE is connected to one PLC, but for I / O devices, there may be multiple IOs connected to one CPE. In industrial scenarios, real-time business communication between PLC and I / O devices is carried out through fixed periodic messages, and their communication relationship is determined during configuration. Due to differences in services and functions, the cycles of different business messages may not be consistent. Even two I / O devices connected to the same CPE may execute services with different communication cycles. For example, Figure 3 The communication cycle between the devices in is shown in Table 1.

[0107] It should be noted that industrial terminals may not have 3GPP communication capabilities. Industrial terminals can communicate using the 3GPP network through terminals in the 3GPP network. Alternatively, for future communications, when industrial terminals have 3GPP communication capabilities, they can be considered terminals in the 3GPP network, such as the UE in Figure 2(a) or Figure 2(b).

[0108] In order to reduce the uplink delay, the embodiment of the present application introduces an uplink pre-scheduling function. Specifically, regardless of whether the terminal sends a scheduling request to the base station, the base station will actively schedule the terminal once every period of time through the pre-scheduling parameter set, and allocate appropriate time-frequency resources to the terminal for the terminal to send and receive data. This method can reduce the delay of the terminal in obtaining the uplink scheduled time-frequency resources.

[0109] In the embodiment of the present application, each pre-scheduling parameter set includes the following three parameters:

[0110] 1) Minimum pre-allocation period (MinPreallocationPeriod): This can be represented by X and refers to the minimum time interval for active pre-allocation.

[0111] 2) Maximum number of pre-scheduled users (PreschUeNumUpperLimit): This can be represented by Y and refers to the maximum number of users that can be pre-scheduled in a time unit, where the time unit can be a symbol, time slot, frame, or second.

[0112] 3) Total amount of scheduled data (PreallocationSize): This can be represented by Z and refers to the total amount of data that can be scheduled for pre-scheduled users.

[0113] Figure 4 A communication method according to an embodiment of the present invention is provided, which includes the following steps:

[0114] Step 401 : The AF determines a first pre-scheduling parameter set and a 5QI corresponding to each pre-scheduling parameter set in the first pre-scheduling parameter set, where the first pre-scheduling parameter set includes pre-scheduling parameter sets corresponding to a plurality of device groups.

[0115] The AF here can be, for example, an Industrial Field Enable Service (IFES) device. In a specific implementation, the IFES can be deployed on the UPF, or deployed together with the UPF on a Mobile Edge Compute (MEC) device.

[0116] As an implementation method, the device group here refers to a group composed of terminals in a 3GPP network, so a device group includes one or more terminals in the 3GPP network.

[0117] As another implementation method, the device group here refers to a group composed of industrial terminals. Therefore, a device group contains one or more industrial terminals. The industrial terminals here do not have the ability to communicate on the 3GPP network, but can communicate using the 3GPP network through terminals on the 3GPP network.

[0118] Take the industrial terminal included in the device group as an example, combined with Figure 3 After the 5G LAN is established, the CPE (such as the terminal of the 3GPP network) goes online and creates an Ethernet or IP type PDU session. The business server then configures the industrial terminal (such as PLC, I / O equipment), obtains the topology information of the field network, and also sets the cycle of the business message in the industrial terminal. The topology information of the field network is used to represent the connection relationship between multiple industrial terminals and CPE. AF can obtain the field network configuration information from the business server, wherein the field network configuration information includes the topology information of the field network and the cycle of the business message in the industrial terminal. The industrial terminal here can be, for example, Figure 3 PLC 1, PLC 2, I / O device 1, I / O device 2, or I / O device 3 in the AF. After obtaining the configuration information, the AF can divide the multiple industrial terminals into multiple device groups, where each device group contains one or more industrial terminals. The AF then determines a pre-scheduling parameter set for each device group. The one or more determined pre-scheduling parameter sets constitute a first pre-scheduling parameter set. Each pre-scheduling parameter set corresponds to one period, and different pre-scheduling parameter sets correspond to different periods.

[0119] Specifically, the AF can group industrial terminals in the field network based on their service message cycles, resulting in multiple device groups. Industrial terminals within the same device group have the same service message cycle, while industrial terminals in different device groups have different service message cycles. It should be noted that if an industrial terminal contains multiple service messages with different cycles, the industrial terminal can be divided into multiple device groups.

[0120] For example, there are 8 industrial terminals in the field network, namely industrial terminal 1 to industrial terminal 8. According to the cycle of the business messages in the industrial terminals, the 8 industrial terminals are grouped as follows:

[0121] Device group 1: {Industrial terminal 1, Industrial terminal 2, Industrial terminal 3};

[0122] Device group 2: {industrial terminal 1, industrial terminal 4, industrial terminal 5, industrial terminal 6};

[0123] Device group 3: {industrial terminal 2, industrial terminal 7, industrial terminal 8};

[0124] The service message period for device group 1 is 1ms, meaning that all industrial terminals in device group 1 have service messages with a period of 1ms. The service period for device group 2 is 2ms, meaning that all industrial terminals in device group 2 have service messages with a period of 2ms. The service period for device group 3 is 4ms, meaning that all industrial terminals in device group 3 have service messages with a period of 4ms. It should be noted that industrial terminal 1 contains both service messages with a period of 1ms and service messages with a period of 2ms, so industrial terminal 1 belongs to both device group 1 and device group 2. Similarly, industrial terminal 2 contains both service messages with a period of 1ms and service messages with a period of 4ms, so industrial terminal 1 belongs to both device group 1 and device group 3.

[0125] After obtaining multiple device groups, a pre-scheduling parameter set can be determined for each device group. Taking any one of the multiple device groups as an example (hereinafter referred to as the first device group), the AF can determine the pre-scheduling minimum interval period in the pre-scheduling parameter set corresponding to the first device group based on the period of the service messages corresponding to the first device group, determine the pre-scheduling maximum number of users in the pre-scheduling parameter set corresponding to the first device group based on the number of devices in the first device group, and determine the total amount of scheduled data in the pre-scheduling parameter set corresponding to the first device group based on the total amount of data in the first device group.

[0126] Taking the above example as an example, device group 1, device group 2, and device group 3 correspond to pre-scheduling parameter set 1, pre-scheduling parameter set 2, and pre-scheduling parameter set 3, respectively, as shown below:

[0127] Pre-scheduling parameter set 1: X = 1ms, Y = 3, Z = 100;

[0128] Pre-scheduling parameter set 2: X = 2ms, Y = 4, Z = 200;

[0129] Pre-scheduling parameter set 3: X=4ms, Y=3, Z=400.

[0130] Specifically, since the industrial terminals in device group 1 all contain service messages with a period of 1ms, the pre-scheduling minimum interval period X in the pre-scheduling parameter set 1 corresponding to device group 1 is set to 1ms. Since device group 1 contains 3 industrial terminals, the pre-scheduling maximum number of users Y in the pre-scheduling parameter set 1 corresponding to device group 1 is set to 3. Since the total amount of data of the 3 industrial terminals in device group 1 is 100, the total amount of scheduled data Z in the pre-scheduling parameter set 1 corresponding to device group 1 is set to 100. Similarly, pre-scheduling parameter set 2 and pre-scheduling parameter set 3 can be obtained. Pre-scheduling parameter set 1, pre-scheduling parameter set 2, and pre-scheduling parameter set 3 can be collectively referred to as the first pre-scheduling parameter set.

[0131] Furthermore, AF can also assign a 5QI to each device group. For example, AF can determine the 5QI corresponding to the first device group based on the QoS requirement information of the first device group, wherein the first device group is any one of the multiple device groups. A 5QI is an index of a set of QoS parameters, and therefore, a 5QI indicates a set of QoS parameters. A set of QoS parameters may include one or more of resource type (Resource Type), priority level (Priority Level), packet delay budget (Packet Delay Budget, PDB), packet error rate (Packet Error Rate, PER), default maximum data burst volume (Default Maximum Data Burst Volume, Default MDBV), and default averaging window (Default Averaging Window).

[0132] Each device group in the multiple device groups corresponds to a pre-scheduling parameter set, each device group corresponds to a 5QI, and therefore each pre-scheduling parameter set corresponds to a 5QI.

[0133] Taking the above example, the assigned 5QI is as follows:

[0134] Device group 1, corresponding to pre-scheduling parameter set 1, corresponding to 5QI 1;

[0135] Device group 2, corresponding to pre-scheduling parameter set 2, corresponding to 5QI 2;

[0136] Device group 3, corresponding to pre-scheduling parameter set 3, corresponding to 5QI 3.

[0137] Step 402: The AF sends the first pre-scheduling parameter set and the 5QI corresponding to each pre-scheduling parameter set in the first pre-scheduling parameter set to the base station. Correspondingly, the base station receives the first pre-scheduling parameter set and the 5QI corresponding to each pre-scheduling parameter set in the first pre-scheduling parameter set.

[0138] Taking the above example as an example, the first pre-scheduling parameter set and the 5QI corresponding to each pre-scheduling parameter set in the first pre-scheduling parameter set sent by the AF to the base station include the following information:

[0139] Pre-scheduling parameter set 1, and 5QI 1 corresponding to pre-scheduling parameter set 1;

[0140] Pre-scheduling parameter set 2, and 5QI 2 corresponding to pre-scheduling parameter set 2;

[0141] Pre-scheduling parameter set 3, and 5QI 3 corresponding to pre-scheduling parameter set 2.

[0142] As an implementation method, the AF may send the first pre-scheduling parameter set and the 5QI corresponding to each pre-scheduling parameter set in the first pre-scheduling parameter set to the base station through the 5G core network. For example, the AF sends the first pre-scheduling parameter set and the 5QI corresponding to each pre-scheduling parameter set in the first pre-scheduling parameter set to the base station via network elements such as the NEF, PCF, and SMF.

[0143] As another implementation method, the AF may also send the first pre-scheduling parameter set and the 5QI corresponding to each pre-scheduling parameter set in the first pre-scheduling parameter set to the base station through the network management device corresponding to the base station. For example, the AF sends the first pre-scheduling parameter set and the 5QI corresponding to each pre-scheduling parameter set in the first pre-scheduling parameter set to the base station through the application programming interface (API) opened by the operation, administration and management (OAM) system of the base station.

[0144] Step 403: The base station receives a data packet of a target service from the terminal, where the data packet includes a QFI.

[0145] The terminal here refers to a terminal in a 3GPP network. The QFI in the data packet of the target service is added to the packet header by the terminal.

[0146] If the device group is composed of terminals in a non-3GPP network (such as industrial terminals), the industrial terminals in the device group transmit and receive data packets for the target service through terminals in the 3GPP network (also known as CPE). The target service here refers to the service in the industrial terminal.

[0147] If the device group is composed of terminals in a 3GPP network, the terminals in the device group can directly send and receive data packets of target services through the 3GPP network. The target services here refer to services in the terminals in the 3GPP network.

[0148] Step 404: The base station determines the first 5QI corresponding to the QFI in the data packet.

[0149] Among them, the correspondence between QFI and 5QI is stored on the base station. For example, after the above step 401, AF can send a policy authorization request to PCF, which carries the service flow description information and QoS requirements of the target service. The service flow description information may include IP five-tuple, virtual local area network (VLAN) identifier, etc. Then PCF generates a packet filter based on the service flow description information. The packet filter can be an Ethernet type packet filter or an IP type packet filter. And, PCF allocates 5QI to the target service according to the QoS requirements. Then, PCF sends a policy and charging control (PCC) rule to SMF. The PCC rule contains a packet filter and QoS attributes, and the QoS attributes contain 5QI. After receiving the PCC rule, SMF allocates QFI to the PCC rule, and generates QoS configuration (QoS profile), QoS rule (QoS rule) and packet detection rule (PDR). The QoS configuration includes the QoS attributes in the PCC rules, the QoS rules include the QFI and packet filters in the PCC rules, and the PDR includes the QFI and packet filters in the PCC rules. The SMF then sends the QFI and QoS configuration to the base station, sends the QoS rules to the terminal, and sends the packet inspection rules to the UPF. Based on the received QFI and QoS configuration, the base station can determine the correspondence between the QFI and the 5QI, for example, determining that QFI 1 corresponds to 5QI 1, QFI 2 corresponds to 5QI 2, and QFI 3 corresponds to 5QI 3.

[0150] In step 404, the base station determines that the QFI in the data packet of the target service corresponds to a first 5QI. The first 5QI may be, for example, 5QI 1, 5QI 2, or 5QI 3. For example, if the base station determines that the QFI in the data packet of the target service is QFI 1, the base station determines, based on the correspondence between QFI 1 and 5QI 1, 5QI 1 corresponding to QFI 1, and 5QI 1 is the first 5QI.

[0151] Step 405: The base station determines a pre-scheduling parameter set corresponding to the first 5QI from the second pre-scheduling parameter set.

[0152] The second pre-scheduling parameter set includes the first pre-scheduling parameter set.

[0153] As an implementation method, the second pre-scheduling parameter set is the same as the first pre-scheduling parameter set. That is, the base station determines the pre-scheduling parameter set corresponding to the first 5QI from the first pre-scheduling parameter set. Taking the above example as an example, assuming that the first 5QI is 5QI 1, the pre-scheduling parameter set corresponding to 5QI 1 in the first pre-scheduling parameter set is determined to be pre-scheduling parameter set 1. Assuming that the first 5QI is 5QI 2, the pre-scheduling parameter set corresponding to 5QI 2 in the first pre-scheduling parameter set is determined to be pre-scheduling parameter set 2.

[0154] As another implementation method, the second pre-scheduling parameter set includes the first pre-scheduling parameter set, and also includes a default pre-scheduling parameter set. The default pre-scheduling parameter set is pre-configured on the base station, or is pre-defined by a protocol. Therefore, the base station determines the pre-scheduling parameter set corresponding to the first 5QI from the first pre-scheduling parameter set and the default pre-scheduling parameter set. As an example, the base station is pre-configured with a default pre-scheduling parameter set a, a default pre-scheduling parameter set b, and a default pre-scheduling parameter set c, wherein the default pre-scheduling parameter set a, the default pre-scheduling parameter set b, and the default pre-scheduling parameter set c correspond to 5QIa, 5QIb, and 5QI c, respectively. If the above-mentioned first 5QI is 5QI 1, the pre-scheduling parameter set determined by the base station is pre-scheduling parameter set 1, and if the above-mentioned first 5QI is 5QI b, the pre-scheduling parameter set determined by the base station is the default pre-scheduling parameter set b.

[0155] As another implementation method, the second pre-scheduling parameter set includes the first pre-scheduling parameter set, and also includes a fourth pre-scheduling parameter set. The fourth pre-scheduling parameter set is obtained by the base station according to the following method: the base station receives the third pre-scheduling parameter set from the AF, and the third pre-scheduling parameter set includes one or more pre-scheduling parameter sets; the base station updates the default pre-scheduling parameter set on the base station according to the third pre-scheduling parameter set to obtain the fourth pre-scheduling parameter set. That is, the base station can update the local default pre-scheduling parameter set according to the third pre-scheduling parameter set received from the AF, thereby obtaining an updated pre-scheduling parameter set, namely the fourth pre-scheduling parameter set. Subsequently, the base station can determine the pre-scheduling parameter set corresponding to the first 5QI from the first pre-scheduling parameter set and the fourth pre-scheduling parameter set. The third pre-scheduling parameter set may be the same as or different from the above-mentioned first pre-scheduling parameter set. The method for AF to generate the third pre-scheduling parameter set is similar to the method for generating the first pre-scheduling parameter set, and will not be repeated here. Taking any default pre-scheduling parameter set on a base station as an example, the default pre-scheduling parameter set includes a first pre-scheduling maximum number of users and a first total amount of scheduled data; any pre-scheduling parameter set in a third pre-scheduling parameter set includes a second pre-scheduling maximum number of users and a second total amount of scheduled data, and the default pre-scheduling parameter set and any pre-scheduling parameter set include the same pre-scheduling minimum interval period, then the base station can update the first pre-scheduling maximum number of users and the first total amount of scheduled data in the default pre-scheduling parameter set based on the second pre-scheduling maximum number of users and the second total amount of scheduled data, to obtain a pre-scheduling parameter set in a fourth pre-scheduling parameter set. This is explained below with reference to specific examples. For example, the base station is pre-configured with a default pre-scheduling parameter set a (X=6ms, Y=4, Z=300), corresponding to 5QIa. The base station receives a third pre-scheduling parameter set from the AF, and the third pre-scheduling parameter set includes the pre-scheduling parameter set 4 (X=6ms, Y=5, Z=400). The base station can update the default pre-scheduling parameter set to the default pre-scheduling parameter set a' (X=6ms, Y=5, Z=400), which corresponds to 5QI a. It should be noted that, as another implementation method, if the AF also sends 5QI 4 corresponding to the pre-scheduling parameter set 4 to the base station, the updated pre-scheduling parameter set a' can also be updated from the corresponding 5QI a to the corresponding 5QI 4.

[0156] As another implementation method, the second pre-scheduling parameter set includes the first pre-scheduling parameter set and also includes a fifth pre-scheduling parameter set. The fifth pre-scheduling parameter set is obtained by the base station from the AF, and the method for the AF to generate the fifth pre-scheduling parameter set is: the AF obtains a default pre-scheduling parameter set, and the AF updates the default pre-scheduling parameter set based on the above-mentioned first pre-scheduling parameter set to obtain the fifth pre-scheduling parameter. For example, the default pre-scheduling parameter set obtained by the AF includes the first pre-scheduling maximum number of users and the first total amount of scheduled data, and any one of the pre-scheduling parameter sets in the first pre-scheduling parameter set includes the third pre-scheduling maximum number of users and the third total amount of scheduled data. The default pre-scheduling parameter set and any one of the pre-scheduling parameter sets include the same pre-scheduling minimum interval period, then the AF updates the first pre-scheduling maximum number of users and the first total amount of scheduled data in the default pre-scheduling parameter set based on the third pre-scheduling maximum number of users and the third total amount of scheduled data to obtain a pre-scheduling parameter set in the fifth pre-scheduling parameter set. The following is an explanation with reference to specific examples. For example, AF obtains the default pre-scheduling parameter set a (X=6ms, Y=4, Z=300), corresponding to 5QI a. The first pre-scheduling parameter set determined by the base station includes pre-scheduling parameter set 5 (X=6ms, Y=8, Z=600). Then, based on the default pre-scheduling parameter set a, an updated default pre-scheduling parameter set a" (X=6ms, Y=8, Z=600) is obtained. The updated default pre-scheduling parameter set a" is a pre-scheduling parameter set in the fifth pre-scheduling parameter set. It should be noted that while AF sends the fifth pre-scheduling parameter set to the base station, it can also send the 5QI corresponding to each pre-scheduling parameter set in the fifth pre-scheduling parameter set to the base station.

[0157] Step 406: The base station pre-schedules uplink resources of the terminal according to the pre-scheduling parameter set corresponding to the first 5QI.

[0158] According to the above solution, since multiple pre-scheduling parameter sets are configured for the base station, the base station can pre-schedule the terminal's uplink resources based on the pre-scheduling parameter sets, thereby reducing the time it takes for the terminal to obtain uplink resources and thereby improving the terminal's communication efficiency. Furthermore, since the AF configures one or more pre-scheduling parameter sets for the base station, the pre-scheduling parameter sets can be dynamically configured or adjusted according to actual needs, facilitating the accurate allocation of corresponding resources to the terminal.

[0159] It should be noted that the pre-scheduling parameter set configured by the AF for the base station and the 5QI corresponding to the pre-scheduling parameter set can be adjusted dynamically. For example, if the AF obtains that the configuration information of the field network has changed, such as adding or reducing industrial terminals, the AF can update the pre-scheduling parameter set and the 5QI corresponding to the pre-scheduling parameter set. For another example, if the AF learns that a new or deleted service has been added to the industrial terminal in the field network, or that the cycle of the existing service of the industrial terminal in the field network has changed, the AF can also update the pre-scheduling parameter set and the 5QI corresponding to the pre-scheduling parameter set. The following is a combination of the above examples to illustrate the update process.

[0160] For example, before the update, the device group, pre-scheduling parameter set, and 5QI determined by AF are as follows:

[0161] Device group 1: {Industrial terminal 1, Industrial terminal 2, Industrial terminal 3};

[0162] Device group 2: {industrial terminal 1, industrial terminal 4, industrial terminal 5, industrial terminal 6};

[0163] Device group 3: {industrial terminal 2, industrial terminal 7, industrial terminal 8};

[0164] Device group 1, device group 2, and device group 3 correspond to pre-scheduling parameter set 1, pre-scheduling parameter set 2, and pre-scheduling parameter set 3, respectively, as shown below:

[0165] Pre-scheduling parameter set 1: X = 1ms, Y = 3, Z = 100;

[0166] Pre-scheduling parameter set 2: X = 2ms, Y = 4, Z = 200;

[0167] Pre-scheduling parameter set 3: X=4ms, Y=3, Z=400.

[0168] Example 1

[0169] If industrial terminal 9 is added and the service message period in industrial terminal 9 is 4ms, the updated device group is as follows:

[0170] Device group 1: {Industrial terminal 1, Industrial terminal 2, Industrial terminal 3};

[0171] Device group 2: {industrial terminal 1, industrial terminal 4, industrial terminal 5, industrial terminal 6};

[0172] Device group 3: {industrial terminal 2, industrial terminal 7, industrial terminal 8, industrial terminal 9};

[0173] Among them, device group 1, device group 2, and device group 3 correspond to pre-scheduling parameters 1, pre-scheduling parameters 2, and pre-scheduling parameters 3, respectively, as shown below:

[0174] Pre-scheduling parameter set 1: X = 1ms, Y = 3, Z = 100;

[0175] Pre-scheduling parameter set 2: X = 2ms, Y = 4, Z = 200;

[0176] Pre-scheduling parameter set 3: X=4ms, Y=4, Z=500.

[0177] And, according to the QoS requirement information of each device group, a 5QI is newly allocated to each device group. It should be noted that if a device group has not changed, the previous 5QI can continue to be used.

[0178] Example 2

[0179] Delete industrial terminal 4, and the updated device group is as follows:

[0180] Device group 1: {Industrial terminal 1, Industrial terminal 2, Industrial terminal 3};

[0181] Device group 2: {industrial terminal 1, industrial terminal 5, industrial terminal 6};

[0182] Device group 3: {industrial terminal 2, industrial terminal 7, industrial terminal 8};

[0183] Among them, device group 1, device group 2, and device group 3 correspond to pre-scheduling parameters 1, pre-scheduling parameters 2, and pre-scheduling parameters 3, respectively, as shown below:

[0184] Pre-scheduling parameter set 1: X = 1ms, Y = 3, Z = 100;

[0185] Pre-scheduling parameter set 2: X = 2ms, Y = 3, Z = 150;

[0186] Pre-scheduling parameter set 3: X=4ms, Y=3, Z=400.

[0187] And, according to the QoS requirement information of each device group, a 5QI is newly allocated to each device group. It should be noted that if a device group has not changed, the previous 5QI can continue to be used.

[0188] Example 3

[0189] The service message period of industrial terminal 3 is changed to 2ms. The updated device group is as follows:

[0190] Device group 1: {Industrial terminal 1, Industrial terminal 2};

[0191] Device group 2: {industrial terminal 1, industrial terminal 3, industrial terminal 4, industrial terminal 5, industrial terminal 6};

[0192] Device group 3: {industrial terminal 2, industrial terminal 7, industrial terminal 8};

[0193] Among them, device group 1, device group 2, and device group 3 correspond to pre-scheduling parameters 1, pre-scheduling parameters 2, and pre-scheduling parameters 3, respectively, as shown below:

[0194] Pre-scheduling parameter set 1: X = 1ms, Y = 2, Z = 50;

[0195] Pre-scheduling parameter set 2: X = 2ms, Y = 5, Z = 250;

[0196] Pre-scheduling parameter set 3: X=4ms, Y=3, Z=400.

[0197] And, according to the demand information of each device group, a 5QI is re-assigned to each device group. It should be noted that if a device group has not changed, the previous 5QI can continue to be used.

[0198] Example 4

[0199] A new service message is added to industrial terminal 1. The period of this service message is 4ms. The updated device group is as follows:

[0200] Device group 1: {Industrial terminal 1, Industrial terminal 2, Industrial terminal 3};

[0201] Device group 2: {industrial terminal 1, industrial terminal 4, industrial terminal 5, industrial terminal 6};

[0202] Device group 3: {industrial terminal 1, industrial terminal 2, industrial terminal 7, industrial terminal 8};

[0203] Among them, device group 1, device group 2, and device group 3 correspond to pre-scheduling parameters 1, pre-scheduling parameters 2, and pre-scheduling parameters 3, respectively, as shown below:

[0204] Pre-scheduling parameter set 1: X = 1ms, Y = 3, Z = 100;

[0205] Pre-scheduling parameter set 2: X = 2ms, Y = 4, Z = 200;

[0206] Pre-scheduling parameter set 3: X=4ms, Y=4, Z=500.

[0207] And, according to the QoS requirement information of each device group, a 5QI is newly allocated to each device group. It should be noted that if a device group has not changed, the previous 5QI can continue to be used.

[0208] Subsequently, the AF may configure the updated pre-scheduling parameters and the corresponding 5QI to the base station.

[0209] The following is a specific example of an industrial field network. Figure 4 The following examples are provided for illustration. Figure 5 A communication method provided in an embodiment of the present application includes the following steps:

[0210] Step 501: AF obtains configuration information of the field network.

[0211] AF can be an IFES device. The field network configuration information includes the field network topology information and the service message cycle in the industrial terminal. Figure 4 Description of embodiments of the present invention.

[0212] Step 502: AF groups the industrial terminals according to the configuration information of the field network.

[0213] Step 503: The AF determines a pre-scheduling parameter set for each device group.

[0214] In step 504, the AF determines a 5QI for each device group.

[0215] Step 505: The AF sends the first pre-scheduling parameter set and the 5QI corresponding to each pre-scheduling parameter set in the first pre-scheduling parameter set to the base station. Correspondingly, the base station receives the first pre-scheduling parameter set and the 5QI corresponding to each pre-scheduling parameter set in the first pre-scheduling parameter set.

[0216] For the specific implementation of the above steps 501 to 505, reference may be made to the description of the above steps 401 to 402.

[0217] Step 506: The AF sends a policy authorization request to the PCF. Correspondingly, the PCF receives the policy authorization request.

[0218] Step 507: The PCF sends the PCC rules to the SMF. Correspondingly, the SMF receives the PCC rules.

[0219] Step 508: The SMF sends the QoS configuration and QFI to the base station. Correspondingly, the base station receives the QoS configuration and QFI.

[0220] Step 509: The SMF sends a PDR to the UPF. Correspondingly, the UPF receives the PDR.

[0221] Step 510: The SMF sends the QoS rules to the terminal. Correspondingly, the terminal receives the QoS rules.

[0222] For the specific implementation of the above steps 506 to 510, reference may be made to the description of the above step 404.

[0223] After the above configuration is performed on the UPF, base station, and terminal, for the uplink data flow of the target service of the industrial terminal, the industrial terminal subsequently sends the uplink data packet of the uplink data flow to the terminal. The terminal matches the uplink data packet of the target service according to the packet filter in the QoS rule.
