[0077] The terminal 120 may be a mobile terminal, such as a mobile phone (or "cellular" phone) and a device with mobile communication capabilities. For example, the terminal 120 may be a portable, pocket-sized, handheld, computer-built-in or vehicle-mounted mobile terminal. In different mobile communication networks, the terminal 120 may have different names, such as: mobile station, mobile, access terminal, user terminal, user agent, user device, or user equipment.

[0078] The mobile communication network 140 may be a Third Generation Partnership Project (3GPP) network. 3GPP networks include, but are not limited to, Long-Term Evolution (LTE) networks, New Radio (NR) networks, and next-generation mobile communication networks based on 5G. The mobile communication network 140 includes at least one network element. Schematically, the mobile communication network 140 includes at least one core network element 142 and at least one access network element 144. The core network element 142 may be a Mobility Management Entity (MME), a Serving Gateway (SGW), a Packet-Data Network Gateway (P-GW or PDN-GW), or other network elements with similar capabilities. The access network element 144 may be a base station. For example, the base station may be a base station (gNB) in a 5G system that adopts a centralized distributed architecture. When the access network element 120 adopts a centralized distributed architecture, it generally includes a centralized unit (CU) and at least two distributed units (DU).

[0079] There is at least one core network element 142 connected to the external network 160, and the core network element 142 has the ability to forward data to realize communication between the terminal 120 and the external network 160. A wireless connection is established between the access network element 144 and the terminal 120 through a wireless air interface.

[0080] The external network 160 may be an external Internet Protocol (IP) network or an external vertical network. Optionally, the external network 160 is a network applicable to vertical industries such as agriculture, manufacturing, logistics, transportation, life services, public services, education, finance, medical care, and energy.

The external network 160 uses a different communication protocol from the mobile communication network 140, that is, it is a network different from the mobile communication network 140.

[0081] Optionally, the external network 160 includes a network element 162, which may be a control network element, a data network element, a terminal, or a sensor. The specific type of the network element 162 is not limited in the embodiment of the present application.

[0082] Optionally, there is a predefined control plane interface between the network element 162 and the network element in the mobile communication network 140 (core network element or access network element). The control plane interface is used to implement the sending and receiving of control plane signaling by the network element 162, and the control plane interface can be a logical interface on a wireless network or a wired network. For example, a logical interface existing on an optical cable, a logical interface existing on an electric cable. The network element 162 can communicate control plane data with the network elements in the mobile communication network 140 through the control plane interface. Alternatively, when there is no control plane interface between the network element 162 and the network elements in the mobile communication network 140, the network element 162 and the mobile communication network 140 can also communicate control plane data with the mobile communication network 140 through ordinary IP data packets, which is not limited in this application.

[0083] Optionally, the network element 162 also has a predefined data plane interface with the network elements (core network elements or access network elements) in the mobile communication network 140. The data plane interface is used to enable the network element 162 to send and receive data packets of related services. The data plane interface can be a logical interface on a wireless network or a wired network. For example, a logical interface on an optical cable, or a logical interface on an electrical cable. The network element 162 can send and receive data packets with the terminal 120 through the data plane interface. Alternatively, when there is no data plane interface between the network element 162 and the network elements in the mobile communication network 140, the network element 162 and the mobile communication network 140 can also communicate data plane data through ordinary IP data packets, which is not limited in this application.

[0084] It should be noted that in Figure 1In the communication network shown, the number of the terminal 120, the core network element 142, the access network element 144, and the network element 162 is only for illustration. In a specific implementation, the number of the terminal 120, the core network element 142, the access network element 144, and the network element 162 can be one or more, and the embodiment of the present application does not limit this.

[0085] Please refer to Figure 2 , which shows a flowchart of a network configuration method provided by an exemplary embodiment of the present application. The first network element in this embodiment may be Figure 1 In the core network element 142 or access network element 144 of the mobile communication network 140 shown in FIG. 1 , the second network element may be Figure 1 The network element 162 in the external network 160 is shown. The method comprises the following steps:

[0086] Step 201, the second network element sends the service attributes of the terminal to the first network element;

[0087] Optionally, there is a service between the second network element and the terminal, and the service data of the service is transmitted through at least one data packet. For example, the service data may be data that the second network element needs to periodically report to the terminal, or the service data may be data that the terminal needs to periodically report to the second network element.

[0088] The service attribute is attribute information related to the service. Optionally, the service attribute is attribute information related to a data packet in the service.

[0089] Illustratively, the service attributes of the terminal include: length information of a data packet, and / or arrival interval information of a data packet.

[0090] Optionally, the second network element sends the service attributes of the terminal to the first network element through a predefined interface. The service attributes may also include an identifier of the terminal. The identifier of the terminal may be a first identifier in the mobile communication network, such as a Cell Radio-Network Temporary Identifier (C-RNTI); or a common identifier in both the mobile communication network and the external network, such as an International Mobile Equipment Identifier (IMEI); or a second identifier of the terminal in the external network, in which case the mobile communication network may store the correspondence between the first identifier and the second identifier of the terminal.

[0091] Step 202: The first network element receives the service attributes of the terminal sent by the second network element;

[0092] Optionally, the first network element receives the service attribute of the terminal sent by the second network element through a predefined interface.

[0093] Step 203: The first network element configures network operating parameters of the terminal according to service attributes of the terminal.

[0094] Optionally, the network operating parameters of the terminal are operating parameters related to the service. The configuration process of the network operating parameters may be to configure the network operating parameters in the terminal; and / or, to configure the network operating parameters related to the terminal in the access network element; and / or, to configure the network operating parameters related to the terminal in the core network element.

[0095] In summary, the network configuration method provided in this embodiment sends the service attributes of the terminal to the first network element in the mobile communication network through the second network element in the external network, and the first network element configures the network operating parameters of the terminal according to the service attributes of the terminal. Different from the related art, the first network element usually configures the network operating parameters of the terminal according to the SR sent by the terminal and the current channel conditions. This application can achieve more optimized configuration of the terminal in combination with the external network, and improve the service transmission efficiency between the terminal and the second network element.

[0096] Based on Figure 2 In an optional embodiment, the service attribute of the terminal includes: length information of the data packet. Figure 3 As shown, the method includes:

[0097] Step 301: The second network element sends service attributes of the terminal to the first network element, where the service attributes include length information of the data packet.

[0098] The data packet of the terminal includes: a data packet sent by the terminal to the second network element, and / or a data packet sent by the second network element to the terminal.

[0099] Optionally, the second network element sends the length information of the data packet of the terminal to the first network element through a predefined interface. The length information can be expressed in different ways. The length information can also be called the size information of the data packet.

[0100] Indicatively, the length information may be any one of the following four types of information:

[0101] 1. The length of the data packet, for example, the length of the data packet is 256 bits;

[0102] 2. The length range of the data packet, for example, the length range of the data packet is [100bit, 120bit];

[0103] 3. The distribution probability of the length of the data packet. For example, the distribution probability of the length of the data packet is 60% for 256 bits and 40% for 128 bits.

[0104] 4. Distribution probability of the length range of the data packet. For example, the probability that the length of the data packet belongs to the range [100bit, 200bit] is 98%, and the probability that it belongs to the range [201bit, 400bit] is 2%.

[0105] Optionally, the service attribute further includes: an identifier of the terminal.

[0106] Step 302, the first network element receives the service attributes of the terminal sent by the second network element;

[0107] Optionally, the first network element receives the length information of the data packet of the terminal sent by the second network element through a predefined interface. The first network element may also receive the identifier of the terminal sent by the second network element at the same time.

[0108] Step 303: The first network element configures network operating parameters of the terminal according to the length information of the data packet.

[0109] The network operating parameters of the terminal are the operating parameters related to the service. The configuration process of the network operating parameters can be to configure the network operating parameters in the terminal; and / or, to configure the network operating parameters related to the terminal in the access network element; and / or, to configure the network operating parameters related to the terminal in the core network element.

[0110] Optionally, the first network element configures at least one network operating parameter related to the terminal according to the length information of the data packet of the terminal. The at least one network operating parameter includes but is not limited to:

[0111] 1. QoS parameters;

[0112] QoS parameters are used to ensure the transmission rate, reliability, bit error rate, and packet loss rate of data packets.

[0113] Indicatively, when the length of a data packet is less than a threshold, a first set of QoS parameters is configured for the terminal; when the length of a data packet is greater than a threshold, a second set of QoS parameters is configured for the terminal. The second set of QoS parameters is superior to the first set of QoS parameters to ensure that the number of retransmissions is reduced when the data packet is large. QoS parameters include, but are not limited to, at least one of: QoS Class Identifier (QCI), Allocation / Retention Priority (ARP), Guaranteed Bit Rate (GBR), and Maximum Bit Rate (MBR). A QCI can be used to define a set of scheduling weights, cache queue management thresholds, link layer protocol configurations, etc. The embodiment of the present application does not limit the specific configuration method of the first network element.

[0114] 2. The number of time and frequency resources;

[0115] The time-frequency resources may be a physical resource block (PRB), a physical resource block pair (PRB pair), a physical resource block group (RBG), or a virtual resource block (VRB). Optionally, a PRB pair includes 12 consecutive subcarriers in the frequency domain and 14 consecutive symbols in the time domain. Among them, the symbol is an orthogonal frequency division multiplexing (OFDM) symbol or a single-carrier frequency division multiple access (SC-FDMA) symbol of a mobile communication system in which the frequency domain where a subcarrier is located is 15kHz, or a symbol of a communication system in which the frequency domain where a subcarrier is located is greater than 15kHz. A PRB occupies a resource of a transmission time length in the time domain. In different mobile communication versions, the transmission time length can be any number of symbols from 1 symbol to 14 symbols.

[0116] Schematically, the first network element can configure the number of time-frequency resources allocated to the terminal based on the length information of the data packet. For example, the length range of the data packet that the terminal needs to upload each time is [100bit, 200bit]. The first network element can allocate uplink time-frequency resources sufficient to transmit 200bit data packets to the terminal each time based on the current channel conditions of the terminal, the modulation and coding method adopted by the terminal, and other information. For another example, if the length of all data packets is 10MB, the first network element configures uplink time-frequency resources sufficient to transmit 10MB of data to the terminal.

[0117] 3. Transmission mode;

[0118] Since different multi-antenna transmission schemes correspond to different transmission modes, the first network element can dynamically configure different transmission modes for the terminal according to the length information of the data packet.

[0119] 4. Safety mechanism;

[0120] Security mechanisms are mechanisms related to identity authentication, data transmission security, etc.

[0121] For example, when the length information of the data packet is less than the first threshold, the first network element starts the security mechanism of the terminal. For another example, when the length information of the data packet is within a specified length range, the first network element starts the security mechanism of the terminal. For another example, when the length information of the data packet is less than the second threshold, the terminal configuration uses the first encryption and decryption algorithm to encrypt and decrypt the data packet; when the length information of the data packet is greater than the second threshold, the terminal configuration uses the second encryption and decryption algorithm to encrypt and decrypt the data packet. Among them, the algorithm complexity of the first encryption and decryption algorithm is less than the algorithm complexity of the second encryption and decryption algorithm, so that the transmission delay introduced by the encryption and decryption process can be reduced when the data packet is small.

[0122] In summary, the network configuration method provided in this embodiment sends the length information of the data packet of the terminal to the first network element in the mobile communication network through the second network element in the external network, and the first network element dynamically configures the network working parameters of the terminal according to the length information of the data packet of the terminal. The first network element configures appropriate network working parameters for the terminal under different length information of the data packet, improves the efficiency and success rate of data packet transmission between the terminal and the second network element, and reduces the delay.

[0123] Based on Figure 3 In an optional embodiment, the service attribute of the terminal further includes: a time period corresponding to the length information. Schematically, the length information of the data packet in the first time period is length information 1, the length information of the data packet in the second time period is length information 2, and the length information of the data packet in the third time period is length information 3. That is, different length information may correspond to different time periods.

[0124] The first network element can configure the network working parameters of the terminal according to the length information of the data packet, the time period corresponding to the length information, and the current time. Schematically, the first network element determines the time period to which the current time belongs, queries the length information of the data packet corresponding to the time period, and configures the network working parameters of the terminal according to the length information of the data packet corresponding to the time period.

[0125] The network configuration method of this embodiment can configure appropriate network operating parameters for the terminal in different time periods according to the length information of the data packets in different time periods, thereby improving the efficiency and success rate of transmitting data packets between the terminal and the second network element in different time periods and reducing the delay.

[0126] Based on Figure 3In an optional embodiment, the service attribute of the terminal further includes: a geographical area corresponding to the length information. Schematically, the length information of a data packet in a first geographical area is length information 1, the length information of a data packet in a second geographical area is length information 2, and the length information of a data packet in a third geographical area is length information 3. That is, different length information may correspond to different geographical areas.

[0127] The first network element can obtain the current geographical location of the terminal, and configure the network operating parameters of the terminal according to the length information of the data packet, the geographical area corresponding to the length information, and the current geographical location of the terminal. Schematically, the first network element determines the target geographical area where the current geographical location of the terminal is located, queries the length information of the data packet corresponding to the target geographical area, and configures the network operating parameters of the terminal according to the length information of the data packet corresponding to the target geographical area.

[0128] The network configuration method of this embodiment can configure appropriate network operating parameters for terminals in different geographical areas according to the length information of data packets in different geographical areas, and can also configure appropriate network operating parameters for terminals when the terminals are in different geographical areas, thereby improving the efficiency and success rate of transmitting data packets between the terminal and the second network element in different geographical areas, and reducing latency.

[0129] Based on Figure 3 In an optional embodiment, the service attribute of the terminal further includes: a PLMN corresponding to the length information. Schematically, the length information of the data packet in the first PLMN is length information 1, the length information of the data packet in the second PLMN is length information 2, and the length information of the data packet in the third PLMN is length information 3. That is, different length information may correspond to different PLMNs.

[0130] The first network element may obtain the current PLMN where the terminal is located, and configure the network operating parameters of the terminal according to the length information of the data packet, the PLMN corresponding to the length information, and the current PLMN where the terminal is located. Schematically, the first network element determines the current PLMN of the terminal, queries the length information of the data packet corresponding to the current PLMN, and configures the network operating parameters of the terminal according to the length information of the data packet corresponding to the current PLMN.

[0131] The network configuration method of this embodiment can configure appropriate network operating parameters for terminals using different PLMNs based on the length information of data packets of different PLMNs, and can also configure appropriate network operating parameters for the terminal when the terminal is in different PLMNs, thereby improving the efficiency and success rate of transmitting data packets between the terminal and the second network element in different PLMNs, and reducing latency.

[0132] Network slicing is a feature introduced in 5G networks. Since 5G networks will support different applications in three scenarios, namely eMBB, mMTC and uMTC, setting up different dedicated networks for different applications will cause a lot of resource waste. Therefore, with the development of Network Function Virtualization (NFV), 5G networks can build different virtual networks for different business needs. Network slicing is to logically define and divide the network based on the common physical infrastructure to form an end-to-end virtual network, each of which has different functional characteristics. A typical network slice includes a set of virtualized access network functions and core network functions to form an end-to-end dedicated network.

[0133] Based on Figure 3 In an optional embodiment, the service attribute of the terminal further includes: network slice information corresponding to the length information. Schematically, the length information of the data packet in the first network slice is length information 1, the length information of the data packet in the second network slice is length information 2, and the length information of the data packet in the third network slice is length information 3. That is, different length information may correspond to different network slices.

[0134] The first network element may obtain the current network slice where the terminal is located, and configure the network operating parameters of the terminal according to the length information of the data packet, the network slice corresponding to the length information, and the current network slice where the terminal is located. Schematically, the first network element determines the current network slice of the terminal, queries the length information of the data packet corresponding to the current network slice, and configures the network operating parameters of the terminal according to the length information of the data packet corresponding to the current network slice.

[0135] The network configuration method of this embodiment can configure appropriate network operating parameters for terminals using different network slices according to the length information of data packets in different network slices, and can also configure appropriate network operating parameters for the terminal when the terminal is in different network slices, thereby improving the efficiency and success rate of transmitting data packets between the terminal and the second network element in different network slices, and reducing latency.

[0136] Based on Figure 2 In an optional embodiment, the service attribute of the terminal includes: arrival interval information of the data packets. Figure 4 As shown, the method includes:

[0137] Step 401: The second network element sends service attributes of the terminal to the first network element, where the service attributes include arrival interval information of data packets.

[0138] The data packets of the terminal include: data packets sent by the terminal to the second network element, and / or data packets sent by the second network element to the terminal. When the data packets are sent regularly, there is an arrival interval between two adjacent data packets (or data packet groups). For example, if the second network element sends a data packet to the terminal every 15 minutes, the arrival interval is 15 minutes.

[0139] Optionally, the second network element sends the arrival interval information of the data packet of the terminal to the first network element through a predefined interface. The arrival interval information can be expressed in different ways. The arrival interval information can also be called the size information of the data packet.

[0140] Illustratively, the arrival interval information may be any one of the following four types of information:

[0141] 1. The duration of the arrival interval of data packets, for example, the arrival interval of data packets is 5 seconds, 10 minutes, 1 hour, etc.;

[0142] 2. The duration range of the arrival interval of the data packets, for example, the duration range of the arrival interval of the data packets is [2 seconds, 4 seconds];

[0143] 4. The distribution probability of the time range of the arrival interval of the data packets. For example, the distribution probability of the time range of the arrival interval of the data packets is 80% for 15 minutes and 20% for 20 minutes.

[0144] 4. The distribution probability of the time range of the arrival interval of the data packets. For example, the probability that the arrival interval of the data packets belongs to the range [8 seconds, 10 seconds] is 98%, and the probability that it belongs to the range [10 seconds, 20 seconds] is 2%.

[0145] Optionally, the service attribute further includes: an identifier of the terminal.

[0146] Step 402: The first network element receives the service attributes of the terminal sent by the second network element;

[0147] Optionally, the first network element receives the arrival interval information of the data packets of the terminal sent by the second network element through a predefined interface. The first network element may also simultaneously receive the identifier of the terminal sent by the second network element.

[0148] Step 404: The first network element configures the network operating parameters of the terminal according to the arrival interval information of the data packets.

[0149] The network operating parameters of the terminal are the operating parameters related to the service. The configuration process of the network operating parameters can be to configure the network operating parameters in the terminal; and / or, to configure the network operating parameters related to the terminal in the access network element; and / or, to configure the network operating parameters related to the terminal in the core network element.

[0150] Optionally, the first network element configures at least one network operating parameter related to the terminal according to the arrival interval information of the data packets of the terminal. The at least one network operating parameter includes but is not limited to:

[0151] 1. QoS parameters;

[0152] QoS parameters are used to ensure the transmission rate, reliability, bit error rate, and packet loss rate of data packets.

[0153] Indicatively, when the arrival interval of data packets is less than a threshold, a first set of QoS parameters is configured for the terminal; when the arrival interval of data packets is greater than the threshold, a second set of QoS parameters is configured for the terminal. The first set of QoS parameters is superior to the second set of QoS parameters to ensure that the number of retransmissions is reduced when the arrival interval of data packets is small. QoS parameters include, but are not limited to: at least one of: QoS Class Identifier (QCI), Allocation / Retention Priority (ARP), Guaranteed Bit Rate (GBR), and Maximum Bit Rate (MBR). A QCI can be used to define a set of scheduling weights, cache queue management thresholds, link layer protocol configurations, etc. The embodiment of the present application does not limit the specific configuration method of the first network element.

[0154] 2. Time and frequency resource location;

[0155] The time-frequency resources may be a physical resource block (PRB), a physical resource block pair (PRB pair), a physical resource block group (RBG), or a virtual resource block (VRB). Optionally, a PRB pair includes 12 consecutive subcarriers in the frequency domain and 14 consecutive symbols in the time domain. Among them, the symbol is an orthogonal frequency division multiplexing (OFDM) symbol or a single-carrier frequency division multiple access (SC-FDMA) symbol of a mobile communication system in which the frequency domain where a subcarrier is located is 15kHz, or a symbol is a symbol of a communication system in which the frequency domain where a subcarrier is located is greater than 15kHz. A PRB occupies a resource of a transmission time arrival interval in the time domain. In different mobile communication versions, the transmission time arrival interval can be any number of symbols from 1 symbol to 14 symbols.

[0156] Indicatively, the first network element may configure the time-frequency resource position allocated to the terminal according to the arrival interval information of the data packet. For example, if the arrival interval range of the data packet that the terminal needs to upload each time is [5s, 6s], the first network element may configure the time-frequency resource position used next time in combination with the time-frequency resource position and arrival interval range used by the terminal this time.

[0157] 3. Transmission mode;

[0158] Since different multi-antenna transmission schemes correspond to different transmission modes, the first network element can dynamically configure different transmission modes for the terminal according to the arrival interval information of the data packets.

[0159] 4. Safety mechanism;

[0160] Security mechanisms are mechanisms related to identity authentication, data transmission security, etc.

[0161] For example, when the arrival interval information of the data packet is less than the first threshold, the first network element starts the security mechanism of the terminal. For another example, when the arrival interval information of the data packet is within the specified arrival interval range, the first network element starts the security mechanism of the terminal. For another example, when the arrival interval information of the data packet is less than the second threshold, the terminal configuration uses the first encryption and decryption algorithm to encrypt and decrypt the data packet; when the arrival interval information of the data packet is greater than the second threshold, the terminal configuration uses the second encryption and decryption algorithm to encrypt and decrypt the data packet. Among them, the algorithm complexity of the first encryption and decryption algorithm is less than the algorithm complexity of the second encryption and decryption algorithm, so that the transmission delay introduced by the encryption and decryption process can be reduced when the arrival interval of the data packet is small.

[0162] 5. Scheduling strategy;

[0163] The scheduling strategy can be divided into an uplink scheduling strategy and a downlink scheduling strategy. When the data packets are sent periodically, the first network element can semi-statically configure the time and frequency resources used by the terminal according to the arrival interval information of the data packets.

[0164] 6. DRX cycle;

[0165] Alternatively, the first network element may configure a discontinuous reception (DRX) cycle for the terminal according to the arrival interval information of the data packet. In each DRX cycle, the terminal may wake up only on one subframe to receive the data packet sent by the second network element; in other DRX cycles, the terminal may turn off the receiving circuit and enter a sleep state, thereby greatly reducing the power consumption of the terminal.

[0166] In summary, the network configuration method provided in this embodiment sends the arrival interval information of the data packets of the terminal to the first network element in the mobile communication network through the second network element in the external network, and the first network element dynamically configures the network operating parameters of the terminal according to the arrival interval information of the data packets of the terminal. The first network element configures appropriate network operating parameters for the terminal under different arrival interval information of the data packets, improves the efficiency and success rate of data packets transmitted between the terminal and the second network element, and reduces the delay.

[0167] Based on Figure 4 In an optional embodiment, the service attribute of the terminal further includes: a time period corresponding to the arrival interval information. Schematically, the arrival interval information of the data packets in the first time period is arrival interval information 1, the arrival interval information of the data packets in the second time period is arrival interval information 2, and the arrival interval information of the data packets in the third time period is arrival interval information 4. That is, different time periods may correspond to different arrival interval information.

[0168] The first network element can configure the network operating parameters of the terminal according to the arrival interval information of the data packets, the time period corresponding to the arrival interval information, and the current time. Schematically, the first network element determines the time period to which the current time belongs, queries the arrival interval information of the data packets corresponding to the time period, and configures the network operating parameters of the terminal according to the arrival interval information of the data packets corresponding to the time period.

[0169] The network configuration method of this embodiment can configure appropriate network operating parameters for the terminal in different time periods according to the arrival interval information of data packets in different time periods, thereby improving the efficiency and success rate of transmitting data packets between the terminal and the second network element in different time periods and reducing latency.

[0170] Based on Figure 4 In an optional embodiment, the service attribute of the terminal further includes: a geographical area corresponding to the arrival interval information. Schematically, the arrival interval information of the data packets in the first geographical area is arrival interval information 1, the arrival interval information of the data packets in the second geographical area is arrival interval information 2, and the arrival interval information of the data packets in the third geographical area is arrival interval information 4. That is, different arrival interval information may correspond to different geographical areas.

[0171] The first network element can obtain the current geographical location of the terminal, and configure the network operating parameters of the terminal according to the arrival interval information of the data packets, the geographical area corresponding to the arrival interval information, and the current geographical location of the terminal. Schematically, the first network element determines the target geographical area where the current geographical location of the terminal is located, queries the arrival interval information of the data packets corresponding to the target geographical area, and configures the network operating parameters of the terminal according to the arrival interval information of the data packets corresponding to the target geographical area.

[0172] The network configuration method of this embodiment can configure appropriate network operating parameters for terminals in different geographical areas according to the arrival interval information of data packets in different geographical areas, and can also configure appropriate network operating parameters for terminals when the terminals are in different geographical areas, thereby improving the efficiency and success rate of transmitting data packets between the terminal and the second network element in different geographical areas, and reducing latency.

[0173] Based on Figure 4 In an optional embodiment, the service attribute of the terminal further includes: the PLMN corresponding to the arrival interval information. Schematically, the arrival interval information of the data packet of the first PLMN is arrival interval information 1, the arrival interval information of the data packet of the second PLMN is arrival interval information 2, and the arrival interval information of the data packet of the third PLMN is arrival interval information 4. That is, different arrival interval information may correspond to different PLMNs.

[0174] The first network element may obtain the current PLMN where the terminal is located, and configure the network operating parameters of the terminal according to the arrival interval information of the data packet, the PLMN corresponding to the arrival interval information, and the current PLMN where the terminal is located. Schematically, the first network element determines the current PLMN of the terminal, queries the arrival interval information of the data packet corresponding to the current PLMN, and configures the network operating parameters of the terminal according to the arrival interval information of the data packet corresponding to the current PLMN.

[0175] The network configuration method of this embodiment can configure appropriate network operating parameters for terminals using different PLMNs according to the arrival interval information of data packets of different PLMNs, and can also configure appropriate network operating parameters for the terminal when the terminal is in different PLMNs, thereby improving the efficiency and success rate of transmitting data packets between the terminal and the second network element in different PLMNs, and reducing the delay.

[0176] Network slicing is a feature introduced in 5G networks. Since 5G networks will support different applications in four scenarios, namely eMBB, mMTC and uMTC, setting up different dedicated networks for different applications will cause a lot of resource waste. Therefore, with the development of NFV, 5G networks can build different virtual networks for different business needs. Network slicing is to logically define and divide the network based on the common physical infrastructure to form an end-to-end virtual network, each of which has different functional characteristics. A typical network slice includes a set of virtualized access network functions and core network functions to form an end-to-end dedicated network.

[0177] Based on Figure 4 In an optional embodiment, the service attribute of the terminal further includes: network slice information corresponding to the arrival interval information. Schematically, the arrival interval information of the data packet in the first network slice is arrival interval information 1, the arrival interval information of the data packet in the second network slice is arrival interval information 2, and the arrival interval information of the data packet in the third network slice is arrival interval information 4. That is, different arrival interval information may correspond to different network slices.

[0178] The first network element may obtain the current network slice where the terminal is located, and configure the network operating parameters of the terminal according to the arrival interval information of the data packet, the network slice corresponding to the arrival interval information, and the current network slice where the terminal is located. Schematically, the first network element determines the current network slice of the terminal, queries the arrival interval information of the data packet corresponding to the current network slice, and configures the network operating parameters of the terminal according to the arrival interval information of the data packet corresponding to the current network slice.

[0179] The network configuration method of this embodiment can configure appropriate network operating parameters for terminals using different network slices according to the arrival interval information of data packets in different network slices, and can also configure appropriate network operating parameters for the terminal when the terminal is in different network slices, thereby improving the efficiency and success rate of transmitting data packets between the terminal and the second network element in different network slices, and reducing latency.
