Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention. In the base station, the importance of user QoS control appears more important, mainly in the following two aspects: in the first aspect, the service performance of each scene is affected, and the scene expansibility is further affected; one of the key characteristics of communication is to support various application scenes, such as high-definition video streaming media, virtual reality, internet of things and the like. The requirements of different application scenes on network service quality are different, and network resource allocation and scheduling strategies are required to be optimized in a targeted manner so as to ensure that users obtain the optimal service quality. There is therefore a need for a suitable QoS control mechanism to match to prioritize high priority service requests in a network.

In the first aspect, the user experience is improved; because the QoS of the user directly influences the service experience of the user, the service experience comprises the experience during mobile phone switching, network video playing, clamping and audio interruption and the like. If the network fails to meet the user's expectations, the user will not continue to use the service, which will seriously affect service promotion. Therefore, a proper QoS mechanism is formulated, differentiated services are carried out according to the user demands, and the user satisfaction degree and the user viscosity can be improved.

In summary, in the base station, the importance of QoS control of the user link can be reflected in expanding the 5G application scenario and improving the user service experience, so how to accurately and efficiently perform QoS control of the base station link is an important topic to be studied in the industry at present.

For the quality control of wireless link service, the related technology mainly performs the quality control of base station link service based on the unified parameter adjustment of the wireless link network transmission layer, that is, performs the parameter adjustment on the wireless link network transmission layer according to the network requirement of the user, and realizes the control of the quality of base station link service. For example, according to the network demands of users, the priorities of the users are uniformly scheduled to be higher levels so as to ensure the network service quality of the users; according to the network demands of users, more bandwidths are uniformly distributed to the users so as to meet the high-speed network demands of the users; according to the network demands of users, the network flow is uniformly controlled to ensure the network service quality; according to the network demands of users, the network delay is uniformly controlled to ensure the network service quality; according to the network demands of users, the network message loss is uniformly controlled so as to ensure the network service quality. The control mode is based on a protocol layer, fair competition among different users and stability of data transmission are ensured mainly by adjusting parameters of wireless signal transmission, services of different user data cannot be accurately distinguished, and service quality requirements required by all kinds of service data are difficult to meet, so that service stability and service quality of a base station are low.

For the quality control of the cable link, the related technology is mainly based on the unified control of the quality of service of the base station link by the parameter adjustment of the transmission layer of the cable link network. For example, for areas of high traffic density where transient incidents need to be eliminated, cache management techniques may be uniformly utilized to provide traffic synchronization; different QoS standards are set in the network according to various services to unify network traffic classification so as to ensure that the service requirements of different types of data can be met; for variable bandwidth requirements in the network, such as VoIP (Voice over Internet Protocol ) telephony, video, bandwidth management can uniformly balance bandwidth resource allocation; the network congestion condition is uniformly limited by limiting the data traffic size sent by the producer, and the speed of opening the connection can be even limited in the case of buffering and the like. The above-mentioned wired link service control methods cannot accurately distinguish the services of different user data, and are difficult to meet the service quality requirements required by all kinds of service data, so that the service stability and the service quality of the base station are low.

In summary, in the related art, the quality of service control of the base station link is generally performed based on the parameters of the transmission layer such as the wired network and the wireless channel, so that the link control of the user data with finer granularity cannot be performed, and the types of service data to be processed by the user are various, so that it is difficult to meet the quality of service requirements required by all types of service data, which results in low service stability and quality of service of the base station.

In view of the above problems, the present embodiment provides a method and an apparatus for controlling quality of service of a base station link, by performing depth recognition on user data to determine a characteristic parameter and a service parameter of a terminal, and adaptively performing closed loop control on a quality of service parameter of a wired link and a quality of service parameter of a wireless link of the base station based on the corresponding characteristic parameter and the corresponding service parameter, so that qualities of service corresponding to different user data are all optimal, thereby improving service stability and quality of service of the base station.

The base station link quality of service control method of the present invention is described below in conjunction with fig. 1-8.

It should be noted that the technical solution provided in the embodiments of the present application may be applicable to various systems. For example, suitable systems may be long term evolution (long term evolution, LTE) systems, LTE frequency division duplex (frequency division duplex, FDD) systems, LTE time division duplex (time division duplex, TDD) systems, long term evolution-advanced (long term evolution advanced, LTE-a) systems, universal mobile systems (universal mobile telecommunication system, UMTS), worldwide interoperability for microwave access (worldwide interoperability for microwave access, wiMAX) systems, new air interface (New Radio, NR) systems and their evolution communication systems, 5g+, B5G, 6G, etc. Terminal devices and network devices may be included in the various systems. Core network parts such as evolved packet system (Evloved Packet System, EPS), 5G system (5 GS) etc. may also be included in the system.

In addition, the method can be applied to various application scenes, such as a communication scene of the internet of things, a video streaming media transmission scene and the like, and the embodiment is not limited in particular.

The method is implemented by a base station, wherein the link of the base station comprises a wired link and a wireless link, the wireless link is used for providing a communication link for transmitting information data from the base station to a terminal (UE), and the wired link is used for providing a communication link for transmitting information data between the base station and a core network.

As shown in fig. 1, a flow chart of a base station link quality of service control method provided in this embodiment is shown, and the method includes the following steps:

step 101, obtaining user plane general packet radio service tunnel protocol GTP-U data packet transmitted by core network;

step 102, analyzing the GTP-U data packet to obtain the characteristic parameters of the target terminal service corresponding to the GTP-U (General Packet Radio Service Tunnelling Protocol User plane, user plane general packet radio service tunnel protocol) data packet and the service parameters of the user data in the GTP-U data packet;

step 103, according to the characteristic parameters and the service parameters, the link service quality parameters of the base station are adjusted; the link quality of service parameters include quality of service parameters of the wired link and quality of service parameters of the wireless link

The user data includes at least one of uplink traffic data, downlink traffic data, TCP (Transmission Control Protocol ) data, or UDP (User Datagram Protocol, user datagram protocol) data.

Because the actual requirement of the wireless communication network design is that the downlink service of the user is far higher than the uplink service, the requirement of the downlink transmission rate is higher than the uplink transmission rate, and the TCP data flow in the user data is connection-oriented and has higher importance than the UDP data flow of the user, in order to simplify the description, the embodiment takes the user data as the downlink TCP data flow as an example, and the base station link service quality control method provided by the embodiment is developed and described, and other user data can be adaptively replaced according to the actual requirement.

Optionally, the base station receives the data packet from the core network, performs UDP port number identification on the data packet, determines that the data packet is a GTP-U data packet if the UDP port number is determined to be 2152, acquires the GTP-U data packet, and enters the base station for processing.

Fig. 2 is a schematic diagram of a message structure of a GTP-U packet provided in this embodiment, where, as shown in fig. 2, the GTP-U packet includes a MAC (Media Access Control ) header, an IP (Internet Protocol, internet protocol) header, a UDP header, a GTP (General Packet Radio Service Tunnelling Protocol, general packet radio service tunneling protocol) header, and a UE data (User Equipment data, terminal data) header;

The GTP header includes a plurality of fields, namely a VER (Version) field for identifying a Version Number of the GTP protocol, a TYPE field for identifying a message TYPE of the GTP protocol, a TEID (Tunnel Endpoint Identifier, tunnel identification) field for identifying a GTP tunnel identification Number, an SN (Serial Number) field for identifying a GTP sequence Number, and a PDU-N (Protocol Data Unit, network layer data unit) field for distinguishing different network layer data units.

The UE data header includes a plurality of fields, an IP field for identifying an internet protocol address of user data, a TCP field for identifying transmission control protocol data, and a TCP data (Transmission Control Protocol data ) field for storing transmission control protocol data, respectively.

And then, analyzing all protocol heads of the GTP-U data packet or analyzing only target protocol heads, such as the GTP protocol heads and the UE data heads, so as to acquire characteristic parameters of target terminal service corresponding to the GTP-U data packet and service parameters of user data in the GTP-U data packet.

The characteristic parameters include, but are not limited to, tunnel identification, user identification code, terminal number, source internet protocol address and source port identification; the so-called traffic parameters include, but are not limited to, acknowledgement character repetition identification, data retransmission identification, and reception window size.

In some embodiments, the parsing step of the GTP-U packet further comprises:

and analyzing the protocol header of the general packet radio service tunneling protocol GTP in the GTP-U data packet and the data segment borne on the GTP to obtain the characteristic parameters and the service parameters.

Optionally, since the GTP protocol header includes the TEID, the GTP protocol header is parsed to obtain the corresponding TEID feature parameter, and the user identification code and the terminal number of the terminal corresponding to the target terminal service may be further obtained according to the TEID.

The Tunnel identifier (Tunnel ID or TEID) is used to identify a unique GTP-U Tunnel identifier between the UE and the AMF (Access and Mobility Management Function, access mobility management) or UPF (User Plane Function, user port function), specifically, when the UE accesses the base station, the base station creates and generates a corresponding Tunnel according to the IMSI (International Mobile Subscriber Identity ) of the UE, and configures the Tunnel with a globally unique identifier. Therefore, a corresponding mapping relation exists between the tunnel identifier and the UE, and the terminal of the target terminal service corresponding to the GTP-U data packet can be determined through the mapping relation, so that whether the target terminal service is the important terminal service or not can be determined according to the characteristic parameters of the target terminal service, and whether the GTP-U data packet is the data packet corresponding to the important terminal service or not is further determined.

Further, the data segment carried on the GTP protocol, that is, the UE data header, may be further parsed to obtain IP data therefrom, where the IP data includes TCP data and UDP data.

Optionally, a protocol number field and a source IP address (hereinafter abbreviated as SrcIP) in an inner layer IP protocol header of the UE data header are parsed, and a protocol number of 6 indicates that the next layer is a TCP protocol, and the SrcIP is recorded, and non-TCP is processed according to the original flow.

Next, the TCP header is parsed. As shown in fig. 3, the TCP protocol header includes the following fields: source port number, destination port number, sequence number, acknowledgement sequence number, reserved field, control field, window size, checksum, emergency pointer, option, and data.

Wherein, the source port number is the port number of the transmitting end; the destination port number is the port number of the receiving end; the serial number is used for sequentially marking the data, so that the data packets are recombined according to the correct sequence; confirmation of sequence number: a sequence number for confirming the data that has been received; the control bit is used for storing flag bits of the URG (Urrgent), the ACK (Acknowledge character, the acknowledgement character), the PSH (Push flag), the RST (Reset flag), the SYN (Synchronize Sequence Numbers, the synchronization sequence number), the FIN (Finish, the release flag) and the like, and is used for controlling the establishment, the termination and the state management of the connection; window size: the receiver informs the window size of the sender for flow control; and (3) checksum: for detecting whether data is in error during transmission. Emergency pointer: indicating the offset of the urgent data in the message segment; options: including some optional fields such as maximum segment length, time stamp, etc.

Optionally, parsing the TCP header to obtain a source Port identification (hereinafter also referred to as Src TCP Port) stored in a TCP source Port field; the TCP source port field of the downstream user data is used to identify the TCP port served by the UE peer. The service flow to which the GTP-U data packet belongs can be uniquely identified through the SrcIP and the Src TCP Port obtained through analysis.

Note that, MSI, UEID, tunnelID in the characteristic parameters obtained by parsing is used for uniquely identifying the terminal corresponding to the target terminal service, and srccip and Src TCP Port identify the service flow to which the GTP-U data packet belongs. In order to facilitate the management of the characteristic parameters of the target terminal service, the characteristic parameters may be stored in a link control information linked list of the base station.

Further, since the TCP header includes fields such as an acknowledgement character repetition identifier (hereinafter also referred to as a repeat ack), a data repetition transmission identifier (hereinafter also referred to as a unsend), and a receiving window size (hereinafter also referred to as a WindowSize), the TCP header is continuously parsed, so that service parameters of user data such as the acknowledgement character repetition identifier, the data repetition transmission identifier, and the receiving window size can be obtained therefrom.

The confirm character repetition mark is used for marking whether ACK is received repeatedly for a plurality of times, such as 3 times, so as to judge whether message data is lost or not and needs quick retransmission; the acknowledgement character repetition mark is obtained by setting an acknowledgement character repetition mark (hereinafter referred to as repeat ACK) according to repeated ACK returned by the UE when the repeated field is received; the specific setting mode can confirm according to actual requirements, if the ACK is determined to be received repeatedly for a plurality of times, the repeated identification of the confirm character is set to be 1, otherwise, the repeated identification of the confirm character is set to be 0.

The data repeated transmission identifier is used for identifying whether packet loss occurs in the message data or not;

the receive window size is used to identify the data flow control situation and thereby determine whether the data packet is lost.

Optionally, after the characteristic parameters and the service parameters are obtained by parsing, the service quality parameters of the wired link and the service quality parameters of the wireless link can be dynamically adjusted based on the characteristic parameters and the service parameters, so that the important TCP service flows of the important UE are ensured to have enough bandwidths, and the service stability and the service quality of the base station are improved.

The manner in which the quality of service parameters of the wireless link are adjusted here includes: based on the characteristic parameters and the service parameters, dynamically adjusting DRBs (Data Radio Bearer, data radio bearers), establishing proprietary bearers, controlling the transmission power of the terminal corresponding to the target terminal service, and other parameters, such as RAT (Radio Access Technology ), or increasing AAU (Active Antenna Unit, active antenna unit) power, to increase wireless signal strength and coverage, thereby improving signal quality of user data transmission, making the user data more stable and reliable before reaching the base station, thereby reducing the possibility of CRC (Cyclic redundancy check ) error in data transmission, or inputting the characteristic parameters and the service parameters into a pre-constructed machine learning model, and implementing adjustment of the quality of service parameters of the wireless link based on the quality of service parameters of the wireless link to be adjusted output by the machine learning model.

The manner in which the quality of service parameters of the wired link are adjusted here includes: based on the characteristic parameters and the service parameters, a data optimization channel between the base station and the core network is established, multi-queue buffering of user data is established, service class protocol fields in the GTP message are changed, or the characteristic parameters and the service parameters are input into a pre-established machine learning model, the identified user important service is preferentially processed and sent in the base station based on the mode of parameter adjustment of the to-be-adjusted cable link service quality parameters output by the machine learning model, so that adjustment of the cable link service quality parameters is realized, and the embodiment is not limited in detail.

According to the base station link service quality control method, the GTP-U data packet is deeply identified to determine the characteristic parameters of the target terminal service corresponding to the GTP-U data packet and the service parameters of the user data in the GTP-U data packet, and the service quality parameters of the wired link and the service quality parameters of the wireless link of the base station are adaptively closed-loop controlled based on the corresponding characteristic parameters and the corresponding service parameters, so that the service quality corresponding to different user data is optimal, and the service stability and the service quality of the base station are improved.

In some embodiments, the characteristic parameters include a tunnel identification, a user identification code, a terminal number, a source internet protocol address, and a source port identification; the user data comprises a Transmission Control Protocol (TCP) data packet, and the service parameters comprise an acknowledgement character repetition identifier, a data repeated transmission identifier and a receiving window size;

according to the importance degree and the congestion degree, a second adjustment strategy is adopted to adjust the service quality parameters of the wired link; the second adjustment strategy comprises at least one of adjustment strategy of kernel and user mode program cooperation, adjustment strategy of multi-queue buffer and adjustment strategy of GTP-U data packet protocol update. Optionally, a mapping relationship is pre-established between the tunnel identifier, the user identifier, the terminal number, the source internet protocol address and the source port identifier and the importance degree of the terminal service of the terminal, so that the importance degree of the target terminal service can be searched and determined according to the tunnel identifier, the user identifier, the terminal number, the source internet protocol address and the source port identifier and the mapping relationship.

Because the confirm character repeated identification, the data repeated transmission identification and the receiving window size can be used for representing whether the packet data is lost or not, the congestion degree of the user data can be determined through congestion logic judgment; alternatively, the character repetition identification, the data repetition transmission identification, and the reception window size are input into a recognition model constructed in advance, and the degree of congestion of the output user data is recognized by the recognition model, which is not particularly limited in this embodiment.

Then, after determining the importance degree of the target terminal service and the congestion degree of the user data, the radio link resource of the base station can be automatically controlled based on at least one of the adjustment strategy of the data radio bearer resource update, the adjustment strategy of the bearer channel resource update and the adjustment strategy of the terminal transmission power update, that is, at least one of the radio bearer resource update, the bearer channel resource update and the terminal transmission power update is performed on the base station; and adjusting the wired link resources according to at least one of an adjustment strategy of the cooperation of the kernel and the user mode program, an adjustment strategy of the multi-queue buffer and an adjustment strategy of the update of the GTP-U data packet protocol, namely at least one of data optimization transmission of the cooperation of the kernel and the user mode program, data optimization transmission of the multi-queue buffer and data optimization transmission of the update of the GTP-U data packet protocol.

By the link service quality control mode, the bandwidths of the wired links between the core networks and the wireless links between the core networks and the mobile user terminal (UE) are autonomously adjusted, so that the user data congestion degree of important terminals is ensured to be serious, namely, higher priority allocation is automatically carried out on the wired links and the wireless links where the TCP business of the user data is located when congestion is generated or is about to be generated, and the base station automatically allocates more bandwidths to the application for transmitting the user data so as to ensure more stable and high-quality service.

In some embodiments, in the case where the first adjustment policy includes an adjustment policy for data radio bearer resource updates, adjusting the quality of service parameter of the radio link with the first adjustment policy according to the importance level and the congestion level includes:

Optionally, the base station may implement the purpose of allocating radio bandwidth resources as needed by adjusting the DRB, thereby implementing the adjustment of the quality of service parameters of the radio link, which specifically includes the following steps:

in step 201, when determining that the importance degree is greater than the importance degree threshold, that is, determining that the target terminal service is an important terminal service, the enb (Evolved Node B, i.e., base station) establishes a DRB between the terminal corresponding to the target terminal service and the base station, that is, allocates a unique DRB identifier to the terminal corresponding to the target terminal service in RRC (Radio Resource Control ) connection, and configures corresponding radio resources, such as RB (Resource Block) number, and Resource configuration such as data transmission mode, in the PHY (Physical) layer.

Step 202, the base station allocates initial RB resources from the available RB pool thereof, and establishes an association relationship between the allocated initial RB resources and DRBs corresponding to terminals corresponding to the target terminal service, so that the terminals corresponding to the target terminal service can utilize the allocated initial RB resources for uplink and downlink data transmission.

In step 203, the base station determines whether congestion occurs in the user data according to the congestion degree of the user data identified by the user data depth identification technology, so as to dynamically determine the number of target resource blocks and the target transmission mode to be allocated corresponding to the target terminal service, and dynamically adjust the number of RB resources and the transmission rate allocated to the target terminal service in the data radio bearer.

Here, determining the number of target resource blocks and the target transmission mode of the target terminal service to be allocated may be that the congestion degree of the user data is input into a pre-constructed neural network model for prediction, or may be that the congestion degree is obtained by searching according to a pre-constructed mapping relationship between the congestion degree and the number of target resource blocks and the target transmission mode, or the allocation is determined according to a pre-configured allocation rule, if it is determined that the congestion degree of the user data is greater than a congestion degree threshold, that is, it is indicated that congestion or impending congestion occurs, more RB resources and higher transmission rates are allocated to the user data, thereby increasing transmission capacity, improving bandwidth utilization and parallel transmission, and reducing transmission delay; if it is determined that the congestion degree of the user data is less than or equal to the congestion degree threshold value within a certain period of time, that is, congestion does not occur, part of the RB resources can be retracted and the transmission rate can be reduced, so that the resource utilization rate can be improved.

In step 204, the base station sends a resource adjustment message to the core network via the communication interface S1 between the base station and the core network, so as to notify the core network that the base station has completed resource adjustment and the bandwidth of the base station has been changed.

In step 205, the base station updates the relevant configuration in the core network to ensure that the core network has corresponding radio resources and traffic capacity to stably and effectively process the corresponding user data.

According to the method provided by the embodiment, through adjusting the physical layer and link layer resources, corresponding wireless resources are adaptively allocated to the DRB, so that when user data of an important terminal is congested, the data processing priority of the DRB can be improved, the MAC scheduling program can grant the UE access right of the DRB more frequently, the data channel capacity of the DRB is improved, and the service stability and the service quality of the base station are improved.

In some embodiments, in a case where the first adjustment policy includes an adjustment policy for bearer channel resource update, adjusting a quality of service parameter of the radio link with the first adjustment policy according to the importance level and the congestion level includes:

transmitting the user data to the configured bearing channel;

Alternatively, the adjustment of the quality of service parameter of the radio link may be achieved by creating a dedicated bearer, allocating a corresponding data transmission rate, bandwidth, delay, priority, etc. to the dedicated bearer according to the importance level and the congestion level, and allocating the dedicated bearer to a specific logical channel or DRB, which comprises the following specific steps:

step 301, when determining that the importance level is greater than the importance level threshold, the base station sends a bearer establishment request of the bandwidth UE to be adjusted (i.e. the terminal corresponding to the target terminal service) to the control service in the core network, where the bearer establishment request is used to request to establish a transport stream of the TCP service of the terminal corresponding to the target terminal service, and designates a QoS attribute of a corresponding priority according to the congestion level.

Step 302, after receiving the bearer establishment request, the core network executes corresponding user policy and service policy according to the bearer establishment request, so as to generate a special bearer instance corresponding to the target terminal service according to the priority and the specific rule.

In step 303, the core network performs corresponding configuration, such as configuring minimum guaranteed bandwidth, maximum packet loss rate, etc., for the private bearer instance corresponding to the target terminal service, and installs or modifies a configuration file on each gateway device, such as a UPF (User Plane Function, user plane protocol gateway) or a P-GW (Packet Data Gateway ), to establish a corresponding private bearer channel.

Step 304, the base station determines a target antenna resource and a target carrier frequency bandwidth according to the congestion degree, and dynamically configures the resource information of the bearing channel according to the target antenna resource and the target carrier frequency bandwidth so as to meet the requirement of a physical link; and can also establish a correct mapping relationship between different logical channels of the bearer channel to place the user data stream into the proprietary bearer channel.

In step 305, during the process of managing and controlling the dedicated bearer, the UPF or the P-GW tracks and records the quality of service metric value of the bearer channel, and returns the quality of service metric value to the core network, so that when the quality of service metric value cannot meet the requirement, the configured resource information of the bearer channel is configured and updated, so that the quality of service metric of the resource information of the bearer channel is optimal, or a decision of whether to overflow, such as skipping loss, recovery, etc., is performed, so as to ensure the normal operation and reliability of data of the base station, and further improve the service stability and quality of service of the base station.

According to the method provided by the embodiment, the special bearing is added, and the resource allocation is adaptively performed according to the importance degree and the congestion degree, so that when the user data of the important terminal is congested, the resource occupancy rate of the special bearing channel can be increased, the capacity of the user data channel is increased, the user data of the important terminal is congested, the highest processing priority level and sufficient resources can be provided, and the service stability and the service quality of the base station are improved.

In some embodiments, in a case where the first adjustment policy includes an adjustment policy for terminal transmit power update, adjusting a quality of service parameter of the wireless link with the first adjustment policy according to the importance level and the congestion level includes:

The target transmit power is used to cause the corresponding congestion level of the user data to be less than the congestion level threshold.

Optionally, the wireless resource usage may be optimized by adjusting the transmission power level of the terminal corresponding to the target terminal service, for example, by increasing TPC power control, to ensure that the signal required to be transmitted by the important terminal is strong enough to increase the data channel capacity, thereby implementing adjustment of the quality of service parameter of the wireless link, which specifically includes the following steps:

executing at least one adjustment on the transmitting frequency of the terminal corresponding to the target terminal service under the condition that the importance degree is greater than the importance degree threshold and the congestion degree corresponding to the user data is greater than the congestion degree threshold; for each adjustment step, the following operations are performed:

Step 401, the base station receives a feedback signal corresponding to last adjustment returned by a terminal corresponding to a target terminal service, detects a service parameter of user data in a TCP service data stream, and determines whether congestion degree is relieved; under the condition that the congestion degree is not relieved, determining the congestion degree after the last adjustment corresponding to the user data according to the feedback signal so as to determine the transmission power corresponding to the current adjustment;

in step 402, the base station sends control signaling to the terminal corresponding to the target terminal service again based on the transmission power corresponding to the current adjustment, so as to instruct the terminal corresponding to the target terminal service to continue to adjust the transmission power according to the transmission power corresponding to the current adjustment, and receive the feedback signal corresponding to the current adjustment returned by the terminal corresponding to the target terminal service, and return to step 401 until the congestion degree corresponding to the user data is less than the congestion degree threshold value, and obtain the target transmission power (hereinafter also referred to as the optimal transmission power) of the terminal corresponding to the target terminal service.

Step 403, the base station determines the target bandwidth resources to be allocated to the terminal corresponding to the target terminal service according to the adjusted optimal transmitting power, so as to allocate the adaptive bandwidth resources to the terminal corresponding to the target terminal service, and provide appropriate bandwidth resources for the terminal, so as to realize data transmission of important TCP service and ensure TCP service performance of the UE.

In some embodiments, where the second adjustment policy includes an adjustment policy for kernel and user mode program cooperation, the step of adjusting the quality of service parameter of the wired link using the second adjustment policy according to the importance level and the congestion level further includes:

Optionally, a GTP-U data optimization channel may be implemented based on the cooperation of the kernel and the user mode program in the base station, so as to implement quality of service parameter adjustment of the wired link, thereby providing more efficient communication and data transmission; meanwhile, processing through a kernel IP protocol stack is avoided for GTP-U data flow, and efficiency is improved; in addition, as the kernel can enter a sleep state when waiting for an event, the mechanism can also reduce the occupancy rate of a CPU (Central Processing Unit ) and improve the system efficiency, so that the user TCP service on the GTP-U can be ensured, and the service stability and the service quality of the base station are improved.

As shown in fig. 4, the specific implementation steps of the data optimization channel include:

in step 501, a shared memory object is created in the kernel, specifically, a shared memory object with a specified name is created by using a shagat function, and an anonymous memory mapping file is mapped. The named shmget function is a function in a shared memory function library, and is used for distributing, applying for or obtaining a shared memory segment in a specified system, namely obtaining a shared memory identifier.

Step 502, mapping the shared memory area to the user space, the shared memory area may be mapped to the user space (virtual memory) using a mmap function, and the memory area may be set to be a readable and writable right.

In step 503, a custom ioctl (input/output control) command is defined in the user mode program, and a_io macro (used for transmitting the command) may be used to generate a unique command value for the command, where the ioctl system call is used in the user mode program, and the command value needs to be transferred as a parameter.

In step 504, the user mode program may use the ioctl system call to pass the command to the kernel and specify, by parameters, a GTP-U packet arrival event waiting in the kernel, at which point the user mode program blocks in the ioctl system call, waiting for the kernel to release the blocking signal.

In step 505, after receiving the ethernet packet, the network card determines whether the IP version number is IPV4 (0 x 04) or IPV6 (0 x 06), and the GTP-U uses only two protocols, i.e., IPV4 and IPV 6. If the IP protocol field is IPV4, judging whether the IP protocol field is 17, namely UDP protocol; if it is IPV6, it is determined whether the next header field is UDP protocol (0 x 11).

Step 506, if the protocol field is UDP, it is determined whether the source port and the destination port are respectively the default port number 2152 (or other specified port numbers) of GTP-U, if so, it indicates that the IP packet is a GTP-U packet, otherwise, it is not. And storing the message judged as the GTP-U into a shared memory area of the kernel.

And 507, releasing a signal after the GTP-U message arrives, recovering the user mode program from the ioctl system call, detecting the GTP-U data in the shared memory area, and forwarding the GTP-U data to a wireless protocol stack PDCP (packet data convergence protocol) module for processing.

Storing user data to a first data processing queue;

The multi-queue buffer processing technology is characterized in that a plurality of different TCP stream services of a UE user are subjected to differentiated processing so as to realize the optimization processing of different service data.

Optionally, a multi-queue buffer processing technology may be adopted to put important user data with higher congestion level into a high priority queue, so that a PDCP (Packet Data Convergence Protocol packet data convergence protocol) module preferentially processes service flows in the high priority queue, thereby implementing adjustment of service quality parameters of a wired link, and further improving service stability and service quality of a base station, as shown in fig. 5, the specific steps of the multi-queue buffer processing are as follows:

step 601, after a terminal corresponding to a target terminal service accesses a base station, the base station allocates a plurality of GTP-U data processing queues for each target, wherein each queue is used for caching data of a TCP stream; the specific way can be to analyze the user TCP protocol head in GTP-U, divide different queues according to the destination IP address and port number of TCP flow, and reserve a highest priority queue.

Step 602, when GTP data is transferred to a GTP user state receiving program, selecting a corresponding first data processing queue according to a destination address and a port number corresponding to user data in the GTP data, and placing the user data to be sent into the corresponding first data processing queue.

In step 603, when it is determined that the importance level of the target terminal service is greater than the importance level threshold and the congestion level of the user data is less than or equal to the congestion level threshold, the PDCP module adopts an average scheduling algorithm to schedule the corresponding data processing queue.

In step 604, if it is determined that the importance level of the target terminal service is greater than the importance level threshold and the congestion level of the user data is greater than the congestion level threshold, the user data is forwarded to the highest priority queue, i.e. the second data processing queue, so that the PDCP module preferentially processes the user data before processing other common queue data.

In some embodiments, the step of adjusting the quality of service parameter of the wired link further comprises:

As shown in fig. 6, the protocol header of the outer layer internet protocol address is called as the IP protocol header between the MAC field and the UDP field; the protocol header of the inner layer internet protocol address is called as the IP protocol header in the UE data field.

Optionally, by changing a Service class protocol field in a GTP-U packet, optimization of an uplink TCP Service can be achieved, specifically, important Service data with serious congestion degree is modified by TOS (Type of Service) in an inner-outer IP protocol header, so that network traffic Qos management is achieved, when other routers and switches are reached, data is also preferentially processed, and end-to-end Qos management is achieved, thereby meeting high Service quality requirements of a message in a network transmission process, and the specific steps are as follows:

in step 701, under the condition that the importance degree is determined to be greater than the importance degree threshold and the congestion degree is greater than the congestion degree threshold, that is, the TCP traffic flow of the important terminal is congested or is about to be congested, the GTP-U data of the TCP traffic flow is modified.

Step 702, based on the PDCP module, the user data is assembled, the TOS field of the inner IP protocol header of the GTP-U packet is modified to be the highest service priority label, and the checksum of the inner IP packet is synchronously updated according to the update result of the TOS field. The TOS field is used to specify the priority and quality of service of IP packets.

Step 702, when the outer layer IP header is encapsulated before forwarding the GTP-U packet to the core network, modifying the TOS field of the outer layer IP header to be of high priority, and synchronously updating the checksum of the outer layer IP packet according to the update result of the TOS field.

According to the method provided by the embodiment, under the condition that the importance degree of the target terminal service corresponding to the GTP-U data packet is larger than the importance degree threshold and the congestion degree of the user data is larger than the congestion degree threshold, the highest service priority mark is configured in the protocol header of the outer Internet protocol address and the protocol header of the inner Internet protocol address of the GTP-U data packet, so that the stability and the service quality of the GTP-U data packet transmission are guaranteed to be optimal, and the service stability and the service quality of the base station aiming at the user data are enabled to be optimal.
