An embodiment of the present disclosure provides a base station transmission self-inspection method, the method is applied to the system shown in FIG. 1 , and the system includes a control system, a base station, and a terminal device. Multiple terminal devices are connected to the base station, and the control system is used as an independent network element or a module in the independent network element outside the base station. The control system is configured to send packet filling task information to the base station, and the base station is configured to create a packet filling message according to the packet filling task information and send the packet filling message to the terminal device, and is also configured to send the packet filling message according to the transmission Parameters and preset thresholds determine base station transmission self-test results.

As shown in FIG. 2 , the base station transmission self-inspection method in the embodiment of the present disclosure may include the following steps S11 to S14.

In step S11, the packet filling task information is obtained from the control system, and the packet filling task information includes at least the packet filling start protocol layer type and the terminal address.

The control system can be used as a control module inside the base station, or as an independent network element or a module in an independent network element outside the base station, configured to perform the task of creating packets, displaying the self-test results of base station transmission, and monitoring the KPI (Key Performance Indication, key performance indicators, such as signaling channel availability rate, voice channel availability rate, signaling channel drop rate, and voice channel assignment failure rate, etc.) and other operations.

The acquisition of the package filling task information from the control system may include: receiving the package filling task information issued by the control system after creating the package filling task; or sending a package filling task request to the control system, and receiving the control system according to the package filling task Packet filling task information sent by request.

In step S12, a packet filling message is created.

After obtaining the packet filling task information, the base station can create a packet filling message according to the configuration parameters carried in the packet filling task information, and the specific information carried in the packet filling message, that is, the packet filling content, can be created according to the packet filling task information In addition to the packet-filling start protocol layer type and terminal address, other configuration parameters are determined to realize the customization of the packet-filling content.

In step S13, according to the packet-filling start protocol layer type, the packet-filling message is sent to the terminal address.

The base station can include different types of protocol layer entities. The control system configures the initial protocol layer type of packet filling in the packet filling task information. The base station needs to start from the protocol layer entity corresponding to the initial protocol layer type of the packet filling internally. Initiate packet filling to the terminal.

In step S14, after the packet filling message is sent to the terminal address, the transmission parameters for sending the packet filling message are determined, and the base station transmission self-inspection result is determined according to the transmission parameters and a preset threshold.

In this step, the base station transmission self-inspection result can be determined according to the transmission parameter and the preset threshold. For example, in the case where the transmission parameter is the packet loss rate, if the transmission parameter is greater than the preset threshold, it can be determined that the base station transmission self-inspection result is There is a fault; if the transmission parameter is less than or equal to the preset threshold, it can be determined that there is no fault in the transmission self-test result of the base station.

The base station transmission self-inspection method provided by the embodiment of the present disclosure first configures the packet filling task information including at least the packet filling initial protocol layer type and the terminal address, creates a packet filling message according to the packet filling task information and sends the packet filling message Send to the terminal device corresponding to the terminal address, and after sending the packet filling message to the terminal address, determine the transmission parameters for sending the packet filling message, and determine the base station transmission self-test result according to the transmission parameters and the preset threshold. Through the above process, it is possible to detect whether there is a fault in the base station, and the detection of the transmission fault of the base station can be realized without relying on the core network side equipment, which can reduce the complexity of the transmission fault detection of the base station, shorten the detection time, and improve the detection efficiency. Moreover, the base station can start filling packets from different internal protocol layers to the designated terminal equipment according to the type of the initial protocol layer, and can comprehensively detect the transmission performance of each protocol layer entity inside the base station.

In some embodiments, the type of the initial protocol layer of the packet filling can be PDCP (Packet Data Convergence Protocol, packet data convergence protocol). The corresponding protocol layer entity initiates packet filling to the terminal, that is, the PDCP entity inside the base station initiates packet filling to the terminal. However, the PDCP layer entity first needs to determine whether the base station has the air interface bearer information of the terminal equipment. Only when the base station has the air interface bearer information of the terminal equipment, the PDCP layer entity will send the filling packet to the terminal equipment. Save the air interface bearer information of the terminal equipment connected to the base station, so that the PDCP layer entity can successfully forward the packet filling message to the terminal equipment.

Correspondingly, the base station transmission self-inspection method may also include the following step S13'.

In step S13', before the packet filling message is sent to the terminal address (that is, step S13), the air interface bearer information of the terminal equipment connected to the base station is obtained and saved, and the air interface bearer information includes access to The terminal address of the terminal equipment of the base station.

According to the initial protocol layer type of the filling packet, sending the filling packet message to the terminal address (that is, step S13) may include the following steps: in the case of querying the corresponding air interface bearer information from the base station according to the terminal address, the The packet filling message is sent to the terminal address.

It should be noted that the air interface bearer information is the correspondence between the IP (Internet Protocol, Internet Protocol) address of the terminal equipment and the wireless bearer RB (Radio Bearer) information, and RB is a channel for carrying data transmission, and the air interface bears In addition to the terminal address, the information also includes radio bearer RB information corresponding to the terminal address.

In some implementations, as shown in Figure 3, the acquiring and storing the air interface bearer information of the terminal equipment connected to the base station (ie step S13') may include the following steps S131' and S132'.

In step S131', receive the service message sent by the terminal equipment connected to the base station, and obtain the air interface bearer information carried in the service message.

After the terminal device is connected to the base station, it can send uplink service messages to the base station. The service messages can include browsing web pages, logging in to APP (Application, application program) and ping (Packet Internet Groper, Internet packet explorer) Packets in business processes such as network IP (Internet Protocol, Internet Protocol) addresses.

When receiving a service message sent by a terminal device that has accessed the base station, the base station can obtain the air interface bearer information of the terminal device from it.

In step S132', if the air interface bearer information carried in the service message is stored locally and the quantity of the air interface bearer information carried in the service message locally stored is less than the preset number, or if there is no locally stored In the case of the air interface bearer information carried in the service message, save the air interface bearer information carried in the service message.

After obtaining the air interface bearer information of the terminal device from the uplink service message, the base station can determine whether the air interface bearer information has been stored locally. When the air interface bearer information is not stored locally, the air interface bearer information may be directly stored. When the air interface bearer information has been stored locally and the quantity of the locally stored air interface bearer information is less than a preset quantity, the air interface bearer information may also be saved.

Specifically, the air interface bearer information may include information such as the IP address of the terminal device. For each terminal device, the base station may store a preset number of air interface bearer information, and maintain a preset number of variables locally to record whether Store a preset number of air interface bearer information. For example, for a terminal device, the base station can store two air interface bearer information including IPv4 (Internet Protocol version 4) addresses and two air interface bearer information including IPv6 (Internet Protocol version 6) addresses of the terminal device, and The local maintenance variables IP14, IP24, IP16, IP26 are used to record whether two air interface bearer information including IPv4 addresses and two air interface bearer information including IPv6 addresses of the terminal device have been stored. If the value of any variable in IP14 and IP24 is invalid_word32, it means that the base station can also store an air interface bearer information including an IPv4 address of the terminal device. If the values of IP14 and IP24 are both invalid_word32, it means that the base station can also store the terminal device. Two air interface bearer information including IPv4 addresses; similarly, if the value of any one of the variables in IP16 and IP26 is invalid_word32, it means that the base station can also store one air interface bearer information including IPv6 addresses of the terminal device. If IP16, IP26 The values of all are invalid_word32, indicating that the base station can also store two air interface bearer information including the IPv6 address of the terminal device.

After determining that the air interface bearer information (obtained from the service message) has been stored locally, the base station can further determine whether the air interface bearer information can be stored by querying locally maintained variables, for example, in the IP type In the case of IPv4 (Internet Protocol Version 4), the base station can determine whether the value of the locally maintained variable IP14 is invalid_word32. If the value of the variable IP14 is invalid_word32, it means that the base station can store the bearer information of the air interface. At this time, the base station directly stores the Air interface bearer information; if the value of the variable IP14 is not invalid_word32, the base station cannot directly determine that the air interface bearer information cannot be stored locally at this time, and needs to determine whether the value of the locally maintained variable IP24 is also invalid_word32 If it is not invalid_word32, it means that the bearer information of the air interface cannot be stored locally, but if the value of IP24 is invalid_word32, it means that the bearer information of the air interface can be stored. At this time, the base station stores the bearer information of the air interface. When the IP type is IPv6 (Internet Protocol Version 6), the base station can judge whether the value of the locally maintained variable IP16 is invalid_word32. If the value of the variable IP16 is invalid_word32, it means that the base station can store the bearer information of the air interface. At this time, the base station directly stores the bearer information of the air interface; if the value of the variable IP16 is not invalid_word32, the base station cannot directly determine that the bearer information of the air interface cannot be stored locally at this time, and needs to determine whether the value of the locally maintained variable IP26 is also invalid_word32. If the value of IP26 is not invalid_word32, it means that the air interface bearer information cannot be stored locally, but if the value of IP26 is invalid_word32, it means that the air interface bearer information can be stored. At this time, the base station stores the air interface bearer information.

In the embodiment of the present disclosure, the control system configures the terminal address in the packet filling task information, that is, specifies the target terminal device to which the base station needs to send the packet filling message for packet filling. The base station can also obtain the address from the control system in advance. Or cooperate with the control system in advance to configure the relevant information of the target terminal device that needs to be filled, and obtain and save the air interface bearer information of the target terminal device by judging whether the terminal device connected to the base station is the target terminal device.

Correspondingly, in some implementation manners, the acquisition and storage of the air interface bearer information of the terminal equipment connected to the base station (that is, step S13') can also be implemented by a target terminal identification method based on the tracking identifier TraceID, for example, When a terminal device accesses the base station, the base station can determine whether there is a TraceID consistent with the pre-configured or pre-acquired TraceID in the access request and other packets. When the terminal device currently accessing the base station is identified as the target terminal device based on the TraceID, the base station can directly acquire and save the air interface bearer information of the terminal device. After obtaining and saving the air interface bearer information of the terminal equipment, the base station can request the control system to obtain packet filling task information.

In addition to identifying whether the terminal device accessing the base station is a target terminal device based on TraceID, the base station may also identify whether the terminal device accessing the base station is a target terminal device based on other information of the terminal device. In some implementation manners, the Obtaining and storing the air interface bearer information of the terminal equipment connected to the base station (ie step S13') can also be achieved in the following manner: in response to receiving the uplink message sent by the terminal equipment connected to the base station, parsing the uplink message In order to obtain the characteristics of the uplink packet, if the characteristics of the uplink packet meet the pre-configured target terminal information, identify and save the IP address and air interface bearer information of the terminal device. The target terminal information may include the protocol type of the uplink message, the IP address of the opposite end, the data packet length of the uplink message, the data packet content of the uplink message, and the like. After obtaining and saving the air interface bearer information of the terminal equipment, the base station can request the control system to obtain packet filling task information.

In some embodiments, the type of the initial protocol layer of the packet filling is RLC (Radio Link Control, radio link control layer protocol). The corresponding protocol layer entity initiates packet filling to the terminal, that is, the RLC entity inside the base station initiates packet filling to the terminal. Generally speaking, the RLC entity can directly send the packet filling message to the terminal device. Correspondingly, according to the packet filling initial protocol layer type, sending the packet filling message to the terminal address (ie step S13) may include the following Step: Send the packet filling message to the terminal address.

In the base station transmission detection scheme, as shown in Figure 4, the packet filling is usually initiated in the core network, that is, from the AMF (Access and Mobility Management Function, access and mobility management function) entity or UPF (User Plane Function, user plane function ) entity and other core network elements initiate packet filling, via AMF or UPF GTPU (General Packet Radio Service Tunneling Protocol User Plane, General Packet Radio Service Tunneling Protocol User Plane), UDP (User Datagram Protocol, User Datagram Protocol)/ TCP (Transmission Control Protocol, Transmission Control Protocol), and IP and other planes are used to encapsulate the packet-filling message, and the packet-filling message is sent to the base station, and the packet-filling message is packaged on the IP, UDP/TCP, GTPU and other planes inside the base station After processing, the packet filling message is sent to the terminal device through the PDCP entity, RLC layer entity, MAC (Media Access Control, media access control) layer entity, and PHY (Physical Layer, physical layer) entity inside the base station, and the terminal device The PHY entity, MAC layer entity, RLC layer entity, and PDCP entity send the packet filling message to the APP of the terminal device.

In the embodiment of the present disclosure, as shown in Figure 5, line ① represents the packet filling process when the initial protocol layer type of packet filling is PDCP, and line ② represents the packet filling process when the initial protocol layer type of packet filling is RLC. Package process. The base station can open the APP client of the open source component Iperf, establish a connection with the Iperf APP server of the terminal device through the Iperf APP client, and then encapsulate the created packet filling message through UDP/TCP, IP and other planes. When the initial protocol layer type of the packet is PDCP, the packet filling message is sent to the terminal device through the PDCP entity, RLC layer entity, MAC layer entity, and PHY entity inside the base station, and the PHY entity, MAC layer entity, and RLC layer entity of the terminal device The entity and the PDCP entity receive the packet filling message; when the initial protocol layer type of the packet filling is RLC, the packet filling message is sent to the terminal device through the RLC layer entity, MAC layer entity, and PHY entity inside the base station, and the terminal device The PHY entity, the MAC layer entity, and the RLC layer entity receive the packet filling message. The embodiment of the disclosure directly initiates packet filling from the APP client of the base station, which can quickly and accurately locate the transmission problem inside the base station, reduces the complexity of base station transmission fault detection, shortens the detection time, and improves the detection efficiency.

At present, a commonly used base station transmission detection method is to check the transmission link problem of the base station through ping. Ping is a command used to check whether the network is smooth or the network connection speed. Ping sends an ICMP (Internet Control Message text protocol) echo request message to the destination, and report whether to receive the desired ICMP echo (ICMP echo response). However, in some scenarios, this method will be considered as a ping attack packet, which is limited by the packet length and number of discarded packets. It can only detect transmission link problems when the base station is no-loaded or low-loaded. The effect of base station transmission problems caused by high load is not obvious. In addition, ICMP is used to transmit control messages. Control messages refer to the network itself, such as whether the network is smooth, whether the host is reachable, and whether the route is available. These control messages do not transmit user data, and cannot detect the transmission of the base station when transmitting user data. question. Existing terminal devices mostly use APP, and APP usually uses TCP protocol to transmit user data. Once the APP freezes and goes offline, it becomes unreliable to detect the transmission problem of the base station through ping. In order to solve the above technical problem, the embodiment of the present disclosure independently detects the transmission problem of the base station by performing TCP/UDP packet filling.

Correspondingly, in some implementation manners, the packet filling task information further includes a packet filling message protocol type, and the packet filling message protocol type includes TCP or UDP.

In addition to the packet-filling start protocol layer type and terminal address, the control system can also configure the packet-filling message protocol type in the packet-filling task information, and the packet-filling message protocol type is TCP or UDP. When the protocol type of the packet filling message is TCP, it is used to instruct the base station to establish a TCP connection with the terminal device and send a TCP downlink packet filling message to the terminal device, or when the protocol type of the packet filling message is UDP, use To instruct the base station to establish a UDP connection with the terminal device and send a UDP downlink packet filling message to the terminal device.

In some implementation manners, the packet filling protocol type is TCP, and the transmission parameter is a packet loss rate.

When the protocol type of the packet filling message in the packet filling task information is TCP, the base station can create a TCP packet filling message, and establish a TCP connection with the terminal device to send the TCP packet filling message to the terminal device. For example, the base station can Open the client of the open source component Iperf, and establish a TCP connection with the Iperf server of the terminal device through the client of Iperf. After connecting to the base station, the terminal device can start the Iperf server, execute the TCP packet receiving command, wait for the establishment of a TCP connection with the Iperf client of the base station and receive the TCP packet filling message sent by the base station. After sending the TCP packet filling message to the terminal device, each protocol layer entity inside the base station can directly count the TCP packet loss rate, and the base station can determine the base station transmission self-inspection result according to the TCP packet loss rate and the preset threshold. The preset threshold may include a first preset threshold, and when the TCP packet loss rate counted by any protocol layer entity of the base station is greater than the first preset threshold, it can be determined that the base station transmission self-inspection result is faulty.

When the protocol type of the packet filling message is TCP, the packet filling task information can also carry other necessary packet filling message configuration parameters such as the packet filling duration, the size of the TCP window, the number of threads, and the packet filling port. After sending the TCP packet filling message to the terminal device, each protocol layer entity inside the base station can also directly count the actual transmission parameters. The base station can also calculate the target transmission parameters according to the configuration parameters such as the TCP window size, and then calculate the actual transmission parameters and the target transmission parameters. parameter ratio. The actual transmission parameter is the actual flow transmitted by each protocol layer entity, the target transmission parameter is the packetized flow configured by the control system, and the ratio of the actual transmission parameter to the target transmission parameter is the flow parameter. The preset threshold may also include a second preset threshold. The base station may compare the traffic parameter with the second preset threshold. When the traffic parameter calculated according to the actual transmission parameter and the target transmission parameter of any protocol layer entity is less than the first When two preset thresholds are used, it can be determined that there is a fault in the transmission self-test result of the base station. The first preset threshold and the second preset threshold may be set according to actual conditions, for example, the second preset threshold may be set to 94%, 95%, 96%, etc., which is not specifically limited in this embodiment of the present disclosure.

In some embodiments, the protocol type of the packet filling message is UDP, the packet filling task information also includes the packet filling bandwidth and the number of threads, the transmission parameter is a traffic parameter, and the transmission of the sending packet filling message is determined. Parameters (that is, described in step S14) may include the following steps: determining target transmission parameters according to packet bandwidth and thread number, counting actual transmission parameters, and determining flow parameters according to target transmission parameters and actual transmission parameters.

When the protocol type of the packet filling message in the packet filling task information is UDP, the base station can create a UDP packet filling message according to the UDP message format shown in Figure 6. As shown in Figure 6, the UDP message includes two Part, one of which is the UDP packet header, including 16-bit source port field, 16-bit destination port field, 16-bit UDP datagram length field and 16-bit check value field; and, the second is UDP data section, including UDP data of optional length. The base station can open the client of the open source component Iperf, and initiate UDP packet filling to the terminal device through the client of Iperf.

After sending the UDP packet filling message to the terminal device, each protocol layer entity inside the base station can also directly count the actual transmission parameters, and the base station can also calculate the target transmission parameters according to the packet filling bandwidth and the number of threads in the packet filling task information, and then calculate The ratio of the actual transfer parameter to the target transfer parameter. The actual transmission parameter is the actual traffic transmitted by each protocol layer entity, the target transmission parameter is the packetized traffic configured by the control system, and the ratio of the actual transmission parameter to the target transmission parameter is the traffic parameter. The preset threshold may also include a third preset threshold. The base station may compare the traffic parameter with the third preset threshold. When the traffic parameter calculated according to the actual transmission parameter and the target transmission parameter of any protocol layer entity is less than the first When three preset thresholds are used, it can be determined that there is a fault in the transmission self-test result of the base station. The third preset threshold can be set according to actual conditions, for example, it can be set to 94%, 95%, 96%, etc., which is not specifically limited in this embodiment of the present disclosure.

When the protocol type of the packet filling message is UDP, the packet filling task information may also carry other necessary configuration parameters of the packet filling message such as the packet filling duration, the packet filling port, and the packet length.

In some embodiments, the base station transmission self-inspection method may further include the following steps: after the base station transmission self-inspection result is determined according to the transmission parameters and the preset threshold (ie step S14), when the base station transmission self-inspection result is existence In the event of a failure, obtain link state information and collect the operation logs of each protocol layer entity in the base station within a preset period of time, and send the operation logs and link state information to the control system.

The link state information is configured to identify the state of the internal transmission link of the base station, including "poor", "general", "good", and "excellent", etc., and the corresponding link state information can be determined according to the transmission parameters, for example, when TCP When the packet loss rate is 10%, the link state information may indicate that the state of the internal transmission link of the base station is "normal". The link state information may be determined while determining the base station transmission self-test result according to the transmission parameter and the preset threshold.

When it is determined that there is a fault in the transmission self-test result of the base station, the base station can obtain the determined link state information, and collect the operation logs of the internal protocol layer entities within the preset time length, and feed back the operation logs and link state information to the The control system is used for the control system to analyze and diagnose the transmission performance of each protocol layer entity. It should be noted that, when it is determined that there is no fault in the transmission self-test result of the base station, the base station may also feed back link state information to the control system for the control system to analyze and diagnose the transmission performance of each protocol layer entity.

It should be noted that the packet filling task information may also carry the packet filling direction, which is used to indicate whether the base station fills the terminal with the packet for the base station transmission self-inspection, or the terminal fills the packet with the base station for the base station transmission self-inspection; and, the terminal The equipment can also obtain bag filling task information from the control system. When the packet filling direction is uplink, the base station receives the packet filling message created and sent by the terminal through the open source component Iperf, determines the transmission parameters of the received packet filling message, and determines the base station transmission self-test result according to the transmission parameters and the preset threshold.

Based on the same technical concept, as shown in FIG. 7 , an embodiment of the present disclosure also provides a base station for performing the base station transmission self-inspection method provided in the above embodiment. The base station may include an acquisition module 101, a creation module 102, The transmission module 103 and the self-test module 104.
