Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a method, system, device and medium for transmitting small packet data for large-scale terminals. Background Art

[0002] In mobile communications based on 5G or 6G networks, for services with large terminals, non-video data packets are generally small, and small packets cause greater performance loss to forwarding nodes. Experimental results show that the maximum forwarding rate of a 10GE network card forwarding a 64-byte small packet is about 1 Gbps, while the maximum forwarding rate of a 1400-byte large packet can reach 8-9 Gbps. At the same time, since the number of small packets forwarded per unit time is greater than that of large packets, the CPU responsible for forwarding will also be in a high-load state for a long time.

[0003] The user plane function in the current 5G standard does not consider the impact of forwarding a large number of small packets on the performance of the forwarding function entity. In large-scale terminal scenarios, a large amount of small packets will have a serious impact on the performance of the forwarding function entity, not only reducing the amount of information forwarded per unit time, but also causing a high CPU usage. Summary of the invention

[0004] In view of the problems in the prior art, the purpose of the present invention is to provide a small packet data transmission method, system, device and medium for large-scale terminals, so as to solve the problem that the user plane function of the 5G standard in the prior art does not consider the impact of forwarding a large amount of small packet data on the performance of the forwarding function entity.

[0008] If so, the first forwarding function entity aggregates the data packets and sends them to the second forwarding function entity.

[0012] If so, the first forwarding function entity transmits the data packet based on the corresponding PDU session; the third preset threshold is less than the second preset threshold.

[0013] Optionally, before the first forwarding function entity aggregates the data packets and sends them to the second forwarding function entity, the method further includes the following steps:

[0016] Optionally, the first forwarding function entity aggregates the data packets and sends them to the second forwarding function entity, including:

[0017] After the small packet aggregation session is successfully established, the first forwarding function entity starts to cache the data packet according to a preset time period;

[0025] Optionally, the first forwarding function entity aggregates the data packets and sends them to the second forwarding function entity, including:

[0026] During the aggregation process, data packets belonging to the QoS flow of the same 5QI are mapped into the same small packet aggregation session.

[0027] Optionally, the first forwarding function entity is a 5G core network or a 6G core network, and the second forwarding function entity is a base station; the first forwarding function entity includes a session management function entity, an access and mobility management function entity, and a user plane function entity; the method includes:

[0059] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention will be comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their repeated description will be omitted.

[0060] like Figure 1 As shown, in the prior art, taking the downlink communication link as an example, when the user terminal 11 requests data from the enterprise server 13, and the data is small non-video data, the enterprise server 13 sends the small packet data to the base station 12 based on the user plane function entity of the mobile network, and the base station 12 then forwards it to the user terminal 11.

[0061] However, when the number of user terminals 11 is large, the number of small packets forwarded per unit time is large. The user plane functional entity in the current 5G standard does not consider the impact of too much forwarding of small packets on the performance of the forwarding device. In a large-scale terminal scenario, a large number of small packets will have a serious impact on the performance of the forwarding device, not only reducing the amount of information forwarded per unit time, but also causing a higher CPU usage.

[0062] So, if Figure 2As shown, an embodiment of the present invention discloses a method for transmitting packet data for large-scale terminals. In this embodiment, there are multiple PDU (Packet Data Unit) sessions between the first forwarding function entity and the second forwarding function entity. One PDU session can correspond to one user terminal. Because only under the premise of multiple PDU sessions, there will be a large amount of packet data forwarding. The above method disclosed in this embodiment includes the following steps:

[0063] S110, the first forwarding function entity obtains the number of data packets whose length is less than a first preset threshold within a unit time from all the above PDU sessions.

[0064] S120, the first forwarding function entity determines whether the number of the data packets is greater than or equal to a second preset threshold.

[0065] If yes, step S130 is executed: the first forwarding function entity aggregates the data packets and sends them to the second forwarding function entity.

[0066] The first forwarding function entity transmits the aggregated large data packet through the GTP (GPRS Tunnelling Protocol) tunnel protocol.

[0067] If not, jump to step S110.

[0068] Specifically, in step S120, when the number of data packets is greater than or equal to the second preset threshold, the first forwarding function entity aggregates the data packets in a time period T. For example, starting from the current time t0, caching data packets, all cached data packets within the time [t0, t0+T] are sequentially spliced ​​and encapsulated into a large data packet.

[0069] The first preset threshold may be 256 bytes, the second preset threshold may be 1000, and the unit time may be 1 second, that is, the first forwarding function entity obtains the number of data packets whose length is less than the first preset threshold and forwarded per second. This application does not impose any restrictions on this.

[0070] In one embodiment of the present application, the first forwarding function entity is a 5G core network or a 6G core network, and the second forwarding function entity is a base station. At this time, the first forwarding function entity includes a session management function entity, an access and mobility management function entity, a policy and charging function entity, and a user plane function entity.

[0071] like Figure 3 As shown, it shows the process of forwarding data packets between the server 23 and the user terminal 21. The server 23 is connected to the user plane function entity, and the user terminal 21 is connected to the base station. Figure 3Two user terminals 21 are shown. The base station 22 is also connected to the access and mobility management function entity and the user plane function entity respectively, and the session management function entity is connected to the access and mobility management function entity, the policy and charging function entity and the user plane function entity respectively.

[0072] Taking the downlink communication link as an example, when the user terminal 21 requests to obtain small packet data, the user plane function entity aggregates the downlink traffic obtained from the server 23 to form a large data packet, and sends it to the base station 22. Then the base station 22 decomposes the large data packet into small data packets, and each small data packet is transmitted to each user terminal 21 through the original PDU session.

[0073] like Figure 4 As shown, the packet data transmission method disclosed in this embodiment includes the steps of:

[0074] S310, the user plane function entity obtains the number of data packets whose length is less than a first preset threshold within a unit time from all PDU sessions.

[0075] S320, the user plane function entity determines whether the number of the data packets is greater than or equal to a second preset threshold.

[0076] If yes, step S330 is executed: the session management function entity sends a session establishment request to the user plane function entity and to the base station through the access and mobility management function entity.

[0077] S340, the user plane function entity and the base station respectively respond to the above session establishment request to establish a small packet aggregation session.

[0078] S350, after the small packet aggregation session is successfully established, the user plane functional entity aggregates the data packets and sends them to the base station.

[0079] If not, jump to step S310.

[0080] In this embodiment, when the number of data packets is greater than or equal to the second preset threshold, the user plane function entity will report to the session management function entity, or send a session establishment trigger instruction, and then the session management function entity will send the above session establishment request.

[0081] In other embodiments, when the communication link is an uplink, the second forwarding function entity is a 5G core network or a 6G core network, and the first forwarding function entity is a base station. This application does not limit this.

[0082] In another embodiment of the present application, another method for transmitting small packet data for large-scale terminals is disclosed. Figure 5 As shown in the above Figure 2Based on the embodiment, it also includes:

[0083] S140, the first forwarding function entity monitors the number of the data packets to determine whether the number of data packets forwarded per unit time is less than a third preset threshold.

[0084] If the number of data packets is less than the third preset threshold, then step S150 is executed: the first forwarding function entity transmits the data packets based on the corresponding original PDU session. The third preset threshold is less than the second preset threshold. If not, then step S130 is continued.

[0085] That is, for example, when the user plane function entity senses that the number of data packets forwarded per unit time is less than the third preset threshold, it reports to the session management function. The session management function decides to cancel the packet aggregation session. After the session is deleted, the packet data is transmitted through the original PDU session. Exemplarily, the third preset threshold may be 800, which is not limited in this application.

[0086] In another embodiment of the present application, another method for transmitting small packets of data to large-scale terminals is disclosed. Figure 2 Based on the embodiment, if the number of data packets is greater than or equal to the second preset threshold, the method further includes the following steps before step S130:

[0087] S160, the session management function entity sends a session establishment request to the first forwarding function entity and the second forwarding function entity respectively.

[0088] S170, the first forwarding function entity and the second forwarding function entity respectively respond to the session establishment request to establish a small packet aggregation session.

[0089] In another embodiment of the present application, another method for transmitting small packet data for large-scale terminals is disclosed. In the method, step S130 includes:

[0090] After the above-mentioned small packet aggregation session is successfully established, the above-mentioned first forwarding function entity begins to cache the above-mentioned data packet according to a preset time period.

[0091] The first forwarding function entity splices the cached data packets in sequence, encapsulates them into a large data packet, and sends the large data packet to the second forwarding function entity.

[0092] In another embodiment of the present application, the session establishment request includes an aggregate frequency. Step S130 includes:

[0093] The first forwarding function entity calculates a preset time period according to the aggregation frequency. Then the first forwarding function entity starts to cache the data packet according to the preset time period. The preset time period is the inverse of the aggregation frequency. In this way, small packet data can be accurately aggregated in a time period.

[0094] In other embodiments, the session establishment request may also include other parameters, such as a destination IP address, which is not limited in this application.

[0095] In another embodiment of the present application, Figure 6 As shown in the above Figure 2 On the basis of the embodiment, that is, on the basis of steps S110 and S120, step S130 is replaced by step S170:

[0096] The first forwarding function entity sequentially splices the data packets to form a large data packet, obtains an offset position index of each data packet, and sends the offset position index and the large data packet to the second forwarding function entity.

[0097] The packet data transmission method disclosed in this embodiment also includes the steps of:

[0098] S180, after receiving the large data packet, the second forwarding function entity decomposes the large data packet according to the offset position index, so as to facilitate accurate decomposition of small packets.

[0099] Alternatively, the first forwarding function entity sends the number of small packets together with the offset position index and the above-mentioned large data packet to the second forwarding function entity, and the second forwarding function entity decomposes the above-mentioned small packets according to the number of small packets and the offset position index.

[0100] In another embodiment of the present application, in the above Figure 2 Based on the embodiment, step S130 includes:

[0101] During the aggregation process, data packets of QoS (Quality of Service) flows belonging to the same 5QI (5-Generation QoS Indicator) are mapped to the same packet aggregation session. Data packets of QoS flows belonging to different 5QIs are mapped to different packet aggregation sessions. In this way, data packets of QoS flows with the same 5QI can obtain the same service strategy (such as bandwidth, packet loss rate), and data transmission can be guaranteed accordingly. Otherwise, data transmission will not be guaranteed accordingly.

[0102] Specifically, QoS flows of the same 5QI can be mapped to the same small packet aggregation session according to the rules pre-configured by the user plane functional entity, or issued by the session management functional entity, or issued by the policy and charging functional entity through the session management functional entity. QoS flows of different 5QIs can be mapped to the same or different small packet aggregation sessions according to the rules pre-configured by the user plane functional entity, or issued by the session management functional entity, or issued by the policy and charging functional entity through the session management functional entity.

[0103] The present application discloses another embodiment below, and exemplarily illustrates the method flow:

[0104] In this embodiment, data is transmitted between the server and the user terminal, and three PDU sessions are performed between the base station and the user plane functional entity. The user plane functional entity is preset with the first preset threshold of 2566 bytes, the second preset threshold of 1000, and the third preset threshold of 900.

[0105] When the user plane functional entity senses that the number of data packets less than 256 bytes forwarded per second is 1500, it reports to the session management functional entity. Based on the report message, the session management functional entity determines to establish a small packet aggregation session. The session management functional entity sends a session establishment request to the base station through the access and mobility management functional entity, where the request carries the IP address 10.1.1.3 assigned to the small packet aggregation session, TEID (Tunnel Endpoint Identifier) ​​= 1001, and the session management functional entity sends a session establishment request to the user plane functional entity at the same time.

[0106] The above session establishment request also carries an aggregation frequency. For example, the aggregation frequency is 1 Hz. Then, after the small packet aggregation session is successfully established, the user plane function entity aggregates the downlink traffic according to the aggregation frequency 1 Hz carried in the session establishment request. The base station aggregates the uplink traffic according to the aggregation frequency 1 Hz carried in the session establishment request.

[0107] For example, at time t0, the aggregation entity (user plane functional entity or base station) starts to cache data packets (length < 256 bytes) that need to enter the small packet aggregation session, and these small packets belong to QoS flow 5QI = 4. That is, the aggregation entity is the user plane functional entity in the downlink, and the aggregation entity is the base station in the uplink.

[0108] Since the aggregation frequency is 1 Hz, the aggregation period is 1 second. At t0+1s, the aggregation entity sequentially concatenates all cached data packets within the time [t0, t0+1s], encapsulates them into a large data packet, and sends them out through the small packet aggregation session.

[0109] At t0+1s, the aggregation entity sequentially concatenates all cached data packets within the time [t0, t0+1s], encapsulates them into a large data packet, and sends them out through the small packet aggregation session. After the small packet data is concatenated, the offset position index of each small packet and the number of small packets contained in the large data packet are obtained.

[0110] The outer GTP-U header of the large data packet contains information about the small packet aggregation session tunnel, including version number = 1, protocol type = 1, message type = GTP-U (GPRS Tunnelling Protocol for the user plane), total length = 1300, TEID = 1001, etc. Figure 7 As shown, the content first includes the number of small packets K=6 in the large data packet and the offset position index indexK=[100,300,500,700,900,1100] of each small packet, and then arranges each small packet in order in the content domain.

[0111] The aggregated large data packet is transmitted through the GTP tunnel of the small packet aggregation session. When the data packet reaches another aggregation entity, the other aggregation entity can decompose all small packets according to K and indexK and process these small packets in the usual way. Then continue to aggregate small packets in the next aggregation cycle.

[0112] When the user plane functional entity senses that the number of data packets with a length less than 256 forwarded per second is 800, it reports to the session management functional entity. The session management functional entity decides to cancel the small packet aggregation session. After the session is deleted, the small packet data is transmitted through the original PDU session.

[0113] It should be noted that all the above embodiments disclosed in this application can be freely combined, and the technical solutions obtained after the combination are also within the protection scope of this application.

[0115] The packet quantity acquisition module 81, the first forwarding function entity obtains the number of data packets whose length is less than a first preset threshold within a unit time from the PDU session.

[0116] The packet quantity determination module 82, the first forwarding function entity determines whether the number of the data packets is greater than or equal to a second preset threshold; if so, the packet aggregation sending module is executed. If not, the packet quantity acquisition module is executed.

[0117] The small packet aggregation and sending module 83, the first forwarding function entity aggregates the data packets and sends them to the second forwarding function entity.

[0118] It can be understood that the small packet data transmission system for large-scale terminals of the present invention also includes other existing functional modules that support the operation of the small packet data transmission system for large-scale terminals. Figure 8 The small packet data transmission system for large-scale terminals shown is only an example and should not bring any limitation to the functions and scope of use of the embodiments of the present invention.

[0123] The request sending module 93, the session management function entity sends a session establishment request to the user plane function entity and to the base station through the access and mobility management function entity.

[0124] The small packet aggregation session establishing module 94, the user plane function entity and the base station respectively respond to the above session establishment request to establish a small packet aggregation session.

[0125] The first aggregation sending module 95, after the small packet aggregation session is successfully established, the above-mentioned user plane function entity aggregates the data packets and sends them to the base station.

[0127] The second judgment module 84, the first forwarding function entity monitors the number of the data packets and judges whether the number of data packets forwarded per unit time is less than a third preset threshold. If yes, the original transmission module 85 is executed. If no, the small packet aggregation sending module 83 is executed.

[0128] The original transmission module 85, the first forwarding function entity transmits the data packet based on the corresponding original PDU session. The third preset threshold is less than the second preset threshold.

[0129] like Fig.11 As shown, another embodiment of the present invention further discloses a packet data transmission system 11 for large-scale terminals. The system, in addition to the above-mentioned packet quantity acquisition module 81 and packet quantity determination module 82, further includes:
