Description

Technical Field

[0001] This article relates to mobile communication technology, and more particularly to a method and apparatus for obtaining the rate of a base station backhaul network and a rate testing system. Background Technology

[0002] 5G communication system base stations are mainly divided into macro base stations and small base stations. Macro base stations are mainly used for outdoor coverage, characterized by their large size and wide coverage area, but the signal range they can cover is limited. Small base stations are mainly used to cooperate with macro base stations for continuous coverage and shallow indoor coverage, and their transmission power is relatively low.

[0003] The deployment of network elements in the backhaul network of macro base stations is relatively stable, therefore the backhaul network of macro base stations is generally considered reliable. However, small base stations typically use the Internet as their backhaul network, which has relatively poor stability. Therefore, investigating the stability of the backhaul network of small base stations is particularly important. In existing technologies, rate tests can be performed between the small base station and the gateway device, and the results of these tests can be used as a basis for judging the stability of the small base station's backhaul network.

[0004] In practical applications, it has been found that the rate obtained by the above method depends on the deployment of the gateway device. That is, if the gateway device corresponding to the small base station is not deployed, the rate of the backhaul network cannot be obtained. In addition, the accuracy of the rate obtained by the above method needs to be further improved. Summary of the Invention

[0007] A method for obtaining the rate of a base station backhaul network is applied to a receiving device, wherein the receiving device is one of a small base station and a speed test server, and the corresponding transmitting device is the other of the small base station and the speed test server, wherein the speed test server is connected to the access device of the core network, and the backhaul network is the Internet between the small base station and the core network, the method comprising: Receive a test request carrying test data, wherein the test data carries an identity identifier for uniquely identifying the target UE, and the test request is used to obtain the rate of the backhaul network of the target UE in the current transmission direction; The rate of the target UE in the current transmission direction is calculated using the test data.

The device includes: The generation module is used to generate test data for a preset target UE, wherein the test data carries an identity identifier used to uniquely identify the target UE. The sending module is used to send a test request carrying the test data, wherein the test request is used to obtain the rate of the backhaul network of the target UE in the current transmission direction.

Therefore, the specific order of steps set forth in the specification should not be construed as a limitation of the claims. Moreover, the claims concerning the method and / or process should not be limited to the steps performed in the written order, and those skilled in the art will readily understand that these orders can be varied and still remain within the spirit and scope of the embodiments of this application.

[0017] In this embodiment of the application, the backhaul network of the small base station is the Internet between the small base station and the core network.

[0018] Figure 1 This is a schematic diagram of the structure of a rate testing system in related technologies. For example... Figure 1 As shown, a rate test was conducted between a small base station and a gateway device. Since the gateway device is deployed between the small base station and the core network, the transmission link between the small base station and the gateway device cannot fully cover the transmission link of the backhaul network.

[0019] Figure 2 This is a schematic diagram of the rate testing system provided in an embodiment of this application. Figure 2 As shown, the transmitting device is one of a small base station and a speed test server, and the receiving device corresponding to the transmitting device is the other of the small base station and the speed test server. That is, when the transmitting device is a small base station, the receiving device is a speed test server; when the transmitting device is a speed test server, the receiving device is a small base station.

[0020] The speed test server is connected to the access equipment of the core network.

[0021] Specifically, the speed test server can be located in the core network. Since the small base station is connected to the core network, the speed test server can connect to the small base station. Alternatively, the speed test server can be located outside the core network (e.g., on the public network), and the speed test server can connect to the small base station using the core network.

[0022] When the speed test server is located in the core network, the transmission link between the sending and receiving devices largely overlaps with the transmission link of the backhaul network. However, when the speed test server is not located in the core network, the transmission link between the sending and receiving devices differs from the backhaul network transmission link. This difference lies in the fact that the transmission link between the sending and receiving devices has an additional segment compared to the backhaul network transmission link; specifically, the transmission link between the speed test server and the core network. As can be seen from the above description, in this embodiment of the application, the transmission link between the transmitting device and the receiving device can completely cover the transmission link of the backhaul network.

[0023] By comparison, it can be seen that the transmission link used for the rate test in this application embodiment can cover the transmission link of the backhaul network, while the transmission link used for the rate test in the related technology cannot cover the transmission link of the backhaul network. Therefore, the accuracy of the rate test results provided by this application embodiment is better than the accuracy of the rate test results in the related technology.

[0024] Furthermore, since speed testing is performed using a speed test server, the involvement of gateway devices is not required. Therefore, the speed testing system provided in this application embodiment reduces the constraints on the network structure in the backhaul network, improves versatility, and has a wider range of applications.

[0025] Furthermore, when the speed test server is located in the core network, the transmission link between the sending and receiving devices largely overlaps with the transmission link of the backhaul network. Therefore, the speed obtained using the method described below can accurately reflect the stability of the backhaul network. When the speed test server is not located in the core network, the transmission link between the sending and receiving devices has an additional segment compared to the backhaul network, which may affect the accuracy of the speed test results to some extent. However, it can still provide guidance for judging the stability of the backhaul network.

[0026] The method provided in the embodiments of this application is described below: Figure 3 This is a flowchart illustrating a method for obtaining the rate of a base station backhaul network, provided in an embodiment of this application. Figure 3 As shown, the method is applied to a transmitting device, and the method includes: Step 301: Generate test data for a preset target UE, wherein the test data carries an identity identifier used to uniquely identify the target UE; This test data serves as the primary data volume required for rate testing, facilitating rate calculation by the receiving device.

[0027] In existing technologies, test data comes from network packet flooding operations between small base stations and gateway devices. Network packet flooding refers to sending a large number of data packets to test the network's resilience and stability.

[0028] In contrast, the data in this application embodiment is not generated randomly, but rather the data of the target UE is generated in a targeted manner. The target UE can be a UE with an unsatisfactory current transmission rate. For example, if the current transmission rate of a certain UE is lower than a preset rate threshold, then the UE can be determined as the target UE.

[0029] In practical applications, the reasons why the current transmission rate of the UE is not ideal may be: 1. There is a problem with the air interface between the UE and the small base station; 2. Performance issues inherent in small base stations; 3. The backhaul network between the small base station and the core network is unstable.

[0030] In existing technologies, maintenance personnel troubleshoot in the order of the aforementioned issues.

[0031] Unlike existing technologies, in this application embodiment, considering that points 2 and 3 above are common problems of UEs with unsatisfactory current transmission rates under small base stations, the problem elimination order provided by this application embodiment is as follows: First, rule out problems with the backhaul network, then rule out problems with the small base stations, and finally rule out problems with the air interface.

[0032] Based on the above exclusion order, in this embodiment of the application, when performing the backhaul network rate test operation, the transmission link used does not pass through the air interface corresponding to the UE and the small base station. This can eliminate the influence of air interface factors, more accurately complete the backhaul network detection, and at the same time reduce the reasons for the target UE's current transmission rate being unsatisfactory.

[0033] Preferably, the IP address of the target UE is used as the identity identifier of the target UE in the test data.

[0034] Specifically, when the current transmission direction is uplink, the source address of the test data is the IP address of the target UE; when the current transmission direction is downlink, the destination address of the test data is the IP address of the target UE.

[0035] Step 302: Send a test request carrying the test data. The test request is used to obtain the rate of the backhaul network of the target UE in the current transmission direction. In one exemplary embodiment, the IP address of the speed test server carried in the test request is used to instruct the test request to obtain the rate of the target UE's backhaul network in the current transmission direction.

[0036] Specifically, when the current transmission direction is uplink, the destination address of the test request can be set to the IP address of the speed test server so that the speed test server can receive the test request and thus complete the calculation of the uplink speed. When the current transmission direction is downlink, the source address of the test request can be set to the IP address of the speed test server. This allows the small base station to determine, after receiving the data, that the data is used for downlink rate testing and is not normal communication data of the target UE, based on the source address of the data, and thus calculate the downlink rate.

[0037] The method provided in this application embodiment utilizes a speed test server connected to the access device of the core network to perform a rate test operation between the small base station and the speed test server using the test data of the target UE, thereby obtaining the backhaul network rate. This improves the accuracy of the backhaul network rate and eliminates the need for the involvement of gateway devices.

[0038] The following is about Figure 3 The method shown is explained below: In an exemplary embodiment, when the transmitting device is a small base station, the method for selecting the target UE includes: Obtain the International Mobile Subscriber Identification Number (IMSI) of the UE to be accessed, wherein the UE to be accessed is the UE requesting access to the small base station; When the IMSI of the UE to be accessed is the same as the reference IMSI stored locally, the UE to be accessed is determined to be the target UE.

[0039] The reference IMSI can be a pre-stored IMSI, such as the IMSI of a commercial UE that has been pre-acquired; or, the reference IMSI can be the IMSI of a UE selected by a small base station based on a preset strategy, for example, the IMSI of a UE with an unsatisfactory transmission rate selected based on the UE's transmission rate in a recent period of time.

[0040] Using IMSI to filter target UEs can ensure accurate acquisition of target UEs because the network address (e.g., IP address) of a UE may change due to changes in its geographical location. In addition, the network address of a UE may also change after re-entering the network in some cases. However, using IMSI will not change in the above situations.

[0041] Furthermore, obtaining the IMSI of the UE to be accessed includes: Send a locally generated Identity Request message to the UE to be accessed, wherein the Identity Request message carries indication information of the core network's Identity Request message; The identification response message received from the identification request message carries the IMSI of the UE to be accessed.

[0042] It should be noted that in the existing communication protocol, the identification request message is sent by the core network and forwarded to the UE via the small base station. The UE then sends an identification response message carrying its own IMSI and forwards it to the core network via the small base station.

[0043] In this embodiment, the small base station simulates the core network and sends an identification request message. It uses the existing communication protocol's interaction process between the core network and the UE to obtain the IMSI of the UE to be accessed, making full use of the existing interaction mechanism in the communication protocol to improve the efficiency of information interaction.

[0044] Specifically, the identification request message can be a Non-Access Stratum (NAS) identification request message, and the identification response message can be a NAS identification response message.

[0045] When the transmitting device is a speed test server, the target UE can be selected from a pre-stored UE list, or, after receiving a speed test request from a small base station, the target UE in the received test request can be used as the local target UE.

[0046] In one exemplary embodiment, the test request is encapsulated based on a tunneling protocol, wherein the test request carries the tunnel identifier of the target UE.

[0047] The tunneling protocol can be the GPRS Tunneling Protocol (GTP), and the tunnel identifier of the target UE serves as a unique identifier for the UE during tunnel transmission.

[0048] Figure 4 This is a flowchart illustrating another method for obtaining the rate of a base station backhaul network provided in an embodiment of this application. Figure 4 As shown, the method is applied to a receiving device, and the method includes: Step 401: Receive a test request carrying test data, wherein the test data carries an identity identifier for uniquely identifying the target UE, and the test request is used to obtain the rate of the backhaul network of the target UE in the current transmission direction; When the receiving device is a small base station, if the source address of the data received from the core network is the IP address of the speed test server, then the received data is determined to be a test request corresponding to any UE. Optionally, when it is determined that the received data is a test request, since the test data is not data from normal communication of the target UE, the small base station will not send the test request to the target UE.

[0049] When the receiving device is a speed test server, the received data is used for speed measurement calculation; more specifically, the received data can be classified according to the identity of the target UE to obtain the test data corresponding to each target UE.

[0050] Preferably, the IP address of the target UE is used as the identity identifier of the target UE in the test data.

[0051] Specifically, when the current transmission direction is uplink, the source address of the test data is the IP address of the target UE; when the current transmission direction is downlink, the destination address of the test data is the IP address of the target UE.

[0052] In one exemplary embodiment, the IP address of the speed test server carried in the test request is used to instruct the test request to obtain the rate of the target UE's backhaul network in the current transmission direction.

[0053] Specifically, when the current transmission direction is uplink, the destination address of the test request can be set to the IP address of the speed test server so that the speed test server can receive the test request and thus complete the calculation of the uplink speed. When the current transmission direction is downlink, the source address of the test request can be set to the IP address of the speed test server. This allows the small base station to determine, after receiving the data, that the data is used for downlink rate testing and is not normal communication data of the target UE, based on the source address of the data, and thus calculate the downlink rate.

[0054] Step 402: Calculate the rate of the target UE in the current transmission direction using the test data; The rate can be calculated based on the amount of test data and the transmission duration of the test data; When the receiving device is a small base station, the downlink rate of the backhaul network can be calculated based on the data volume of the test data for the same UE and the transmission duration of the test data; when the receiving device is a speed test server, the uplink rate of the backhaul network can be calculated based on the data volume of the test data for the same UE and the transmission duration of the test data.

[0055] The method provided in this application embodiment utilizes a speed test server connected to the access device of the core network to perform a rate test operation between the small base station and the speed test server using the test data of the target UE, thereby obtaining the backhaul network rate. This improves the accuracy of the backhaul network rate and eliminates the need for the involvement of gateway devices.

[0056] The method provided in the embodiments of this application is illustrated below with application examples: Figure 5 This is a flowchart illustrating the method for obtaining the uplink rate of the backhaul network provided in an embodiment of this application. Figure 5 As shown, the method includes: Step 501: The small base station receives the uplink speed test request from the backhaul network; Step 502: The small base station obtains the IMSI of the UE to be accessed; Step 503: The small base station determines whether the IMSI of the UE to be accessed is the reference IMSI; If so, proceed to step 504; otherwise, the process ends.

[0057] Step 504: The small base station takes the UE to be accessed as the target UE and generates test data for the target UE; Step 505: The small base station encapsulates the test data into tunnel data and sends it to the speed test server; Step 506: The speed test server receives the test data; Step 507: The speed test server calculates the speed test data to obtain the uplink speed of the backhaul network, and the process ends.

[0058] The method provided in this application uses the test data of the target UE to complete the uplink rate test between the small base station and the speed test server to obtain the uplink rate of the backhaul network, thereby improving the accuracy of the uplink rate of the backhaul network.

[0059] Figure 6 This is a flowchart illustrating the method for obtaining the downlink rate of the backhaul network provided in an embodiment of this application. Figure 6 As shown, the method includes: Step 601: The speed test server generates test data for the preset target UE; Step 602: The speed test server sends test data; Step 603: The small base station determines whether the source address of the received data is the IP address of the speed test server; If so, proceed to steps 604 and 605; otherwise, proceed to step 606. Step 604: Small base station acquires test data; Step 605: The small base station calculates the speed measurement data to obtain the downlink rate of the backhaul network, and the process ends.

[0060] Step 606: The small base station forwards the data according to the destination address of the received data, and the process ends.

[0061] The method provided in this application uses the test data of the target UE to complete the downlink rate test between the small base station and the speed test server to obtain the downlink rate of the backhaul network, thereby improving the accuracy of the downlink rate of the backhaul network.
