technical field

The invention relates to the technical field of wireless communication, in particular to a wireless network testing system, testing method and device.

Background technique

In a wireless communication system, the performance of the wireless network has a direct impact on whether the user's mobile terminal can communicate normally. Therefore, testing the performance of the wireless network is the key to ensuring the service quality of the wireless communication system.

At present, wireless dial test technology has been widely used in wireless communication systems as an important means of wireless communication network performance detection. By implementing wireless dial test technology in wireless communication systems, the performance of wireless networks can be evaluated, thereby providing network optimization and maintenance work. Reliable data support. As shown in Figure 1, it is a schematic diagram of a test system for testing wireless network performance based on wireless dial test technology, the test system includes:

Dial test platform 101, dial test terminal 102 and base station 103;

in:

The dial test platform 101 and the dial test terminal 102 communicate based on the transmission network 1 and the wireless network 2 ; the dial test terminal 102 and the base station 103 communicate through the wireless network 3 . In practical applications, the wireless network 2 and the wireless network 3 may correspond to different base stations, or may correspond to the same base station.

The wireless network is tested based on the system architecture shown in FIG. 1 , that is, the wireless network 3 between the dial test terminal 102 and the base station 103 is tested. Specifically, the process of testing based on the system architecture is shown in Figure 2, including the following steps:

Step 201 , the dial test platform 101 sends a test command to the main control board in the transmission network 1 .

Step 202 , the main control board in the transmission network 1 determines the transmission path of the test command inside the transmission network 1 .

Step 203, the transmission network 1 sends a test command to the last transmission device on the transmission path according to the determined transmission path.

Step 204 , the last transmission device in the transmission path sends the test command to the dial-up test terminal 102 through the wireless network 2 .

Step 205 , after receiving the test instruction, the dial test terminal 102 sends the dial test instruction to the base station 103 through the wireless network 3 , and obtains a dial test result according to the feedback from the base station 103 .

Step 206 , the dial test terminal 102 sends the dial test result to the dial test platform 101 through the wireless network 2 and the transmission network 1 .

Step 207 , the dial test platform 101 determines the performance of the wireless network 3 according to the dial test result fed back by the dial test terminal 102 .

Based on the test system shown in Figure 1 and the test process shown in Figure 2, the evaluation of wireless network performance can be realized, but in practical applications, there are the following problems:

1. The realization of the above-mentioned dial test process requires the dial test personnel to hold the dial test terminal 102 to the coverage area of the wireless network 3. After receiving the test command sent by the dial test platform 101 through the transmission network 1 and the wireless network 2, the dial test personnel Use the dial test terminal 102 to perform dial test. Since the premise of realizing the existing dial testing process is that the dial test personnel hold the dial test terminal 102 to the coverage area of the wireless network 3, so the real-time performance of the wireless network 3 test cannot be guaranteed.

2. In the above-mentioned dial test process, after the dial test terminal 102 obtains the dial test result, it needs to send the dial test result to the dial test platform 101 through the wireless network 2 and the transmission network 1, and the dial test platform determines according to the received dial test result The performance of the wireless network. Since the feedback process of the dial test result depends on the wireless network 2, if there is an abnormality in the wireless network 2, it cannot be guaranteed that the dial test result is sent to the dial test platform 101 normally, or the dial test result received at the dial test platform 101 shows that the wireless When the network is abnormal, it cannot be determined whether it is the abnormality of the wireless network 2 or the abnormality of the wireless network 3, thereby affecting the accuracy of the test of the wireless network 3.

To sum up, the dial testing technology implemented based on the existing technology has low real-time performance for wireless network testing and low accuracy of test results.

And in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

Embodiment one

According to the first embodiment of the present invention, a wireless network testing system is provided. The wireless network testing system based on the wireless network testing system provided by the first embodiment can improve the real-time performance and accuracy of the wireless network testing.

As shown in Figure 3, the wireless network testing system provided by the first embodiment mainly includes:

The control device 301 and the transmission devices 302 distributed in the transmission network 1 .

In practical applications, there may be one transmission device 302 distributed in the transmission network 1, or there may be multiple transmission devices 302. The wireless network test system shown in FIG. 3 includes two transmission devices 302 as an example.

The communication system involved in testing based on the test system shown in FIG. 3 is shown in FIG. 4 , the communication system includes the test system shown in FIG. Communication, the wireless network 2 is the wireless network 2 under test. In practical applications, there may be one or more base stations 303. Correspondingly, there may be one or more wireless networks 2 where the transmission device 302 communicates with the base station 303. The communication system shown in FIG. 4 includes one base station 303 as an example .

Specifically, the main functions of each device included in the wireless network testing system are as follows:

The control device 301 is configured to send a test instruction to the transmission device 302 in the transmission network 1 through the transmission network 1; and receive a test result fed back by the transmission device 302 in the transmission network 1 according to the test instruction;

The transmission device 302 is configured to receive the test instruction sent by the control device 301, and according to the test instruction, send test information to the base station 303 through the wireless network 2 under test, and after determining the test result of the wireless network 2 according to the feedback from the base station, pass The transmission network 1 sends the determined test result to the control device 301 .

In the preferred implementation manner provided by Embodiment 1 of the present invention, when the transmission network 1 includes multiple transmission devices 302, the optimal transmission device 302 may be assigned to the wireless network under test to perform the test process. Specifically, to achieve this purpose, the transmission device 302 included in the system shown in FIG. 3 is specifically used for:

Before sending the test information to the base station 303 through the wireless network 2 under test, determine whether it meets the processing conditions for the test instruction;

If yes, execute the step of sending test information to the base station 303 through the tested wireless network 2, if not, forward the test command to the transmission equipment 302 distributed in the transmission network 1 that meets the processing conditions for the test command.

Embodiment 1 of the present invention also provides a preferred embodiment for the transmission device 302 to determine whether it meets the processing conditions for the test instruction. Specifically, the above transmission device 302 is specifically used for:

Before sending test information to the base station 303 through the wireless network 2 under test, determine whether the self-identification matches the identification carried in the received test instruction;

If yes, then determine that it meets the processing conditions for the received test instructions; if not, determine that it does not meet the processing conditions for the received test instructions.

Embodiment 1 of the present invention also provides a preferred implementation manner in which the transmission device 302 forwards the test instruction when it determines that it does not meet the processing conditions for the received test instruction. Specifically, the above transmission device 302 is specifically used for:

When it is determined that it does not meet the processing conditions for the received test command, it forwards the test command to the transmission equipment 302 distributed in the transmission network 1 that meets the processing conditions for the test command according to the identifier carried in the test command.

In the embodiment of the present invention, the communication between the control device 301 and the transmission device 302 can be based on the network management channel in the transmission network 1, that is, the control device 301 sends control information such as test instructions to the transmission device 302 through the network management channel, and the transmission device 302 passes through the network management channel. The channel sends feedback information such as test result information to the control device 301; correspondingly, the communication between the transmission devices 302 can also be based on the network management channel in the transmission network 1, that is, the transmission devices 302 forward test instructions through the gateway channel. Specifically, the network management channel is a communication channel between the network management device (such as the control device 301 ) and the network element device (such as the transmission device 302 ) and between network element devices. In different networks, the specific implementation of the network management channel is different. For example, for an SDH network, the network management channel is generally a channel based on transmission overhead bytes; for a PON (passive optical network), the network management channel is generally a channel based on OMCI (Operation Management Control Interface); for PTN (Packet Transport Network ), and the network management channel is generally an independent tunnel. It should be understood that the technical solutions provided by the embodiments of the present invention are applicable to various network architectures, and the gateway channel for communication between the control device 301 and the transmission device 302 and between the transmission devices 302 also has different implementation methods according to the specific network structure adopted. . In the subsequent embodiments, the network management channel is used as an example to describe the transmission overhead bytes in the SDH network.

In the preferred implementation mode provided by Embodiment 1 of the present invention, the transmission devices 302 can forward test instructions based on the transmission overhead bytes in the transmission network 1, specifically:

The transmission device 302 is specifically configured to forward the test instruction through the transmission overhead bytes in the transmission network 1 to the transmission devices 302 distributed in the transmission network 1 that meet the processing conditions for the test instruction.

In the preferred implementation mode provided by Embodiment 1 of the present invention, before the control device 301 sends a test instruction to the transmission device 302, it can detect each transmission device 302, specifically:

The control device 301 is specifically configured to determine the transmission device 302 in the normal working state among the multiple transmission devices 302 in the transmission network 1;

Send a test instruction to one of the determined transmission devices 302 in a normal working state through the transmission network 1 .

Through the above preferred implementation mode provided by Embodiment 1 of the present invention, the control device 301 detects each transmission device in the transmission network 1 before sending the test command to the transmission device 302, and sends the test command to the detected normal working The transmission device 302 adopts this method to avoid sending test instructions to the transmission device 302 in an abnormal working state, thereby ensuring that the sent test instructions can be executed.

Based on the above-mentioned wireless network testing system provided by Embodiment 1 of the present invention, the control function to the base station can be further implemented, for example, to control the restart of the base station, etc., specifically:

The control device 301 is further configured to send a control instruction to the base station to the transmission device 302 through the transmission network 1, for example, an instruction to control the restart of the base station;

Correspondingly, the transmission device 302 is further configured to receive a control instruction for the base station sent by the control device 301, and control the base station according to the received control instruction.

In Embodiment 1 of the present invention, the transmission process of the control command to the base station in the transmission network 1 is basically the same as the transmission process of the test command in the transmission network 1 , and will not be repeated here.

The wireless network test system provided by Embodiment 1 of the present invention can be based on an actual communication network, with little improvement to the network, and the specific implementation method is as follows:

The control device 301 can be implemented by integrating the existing dial test platform. The dial test platform is mainly responsible for remotely issuing test instructions, that is, inputting the remote dial test module on the network management software (that is, realizing the wireless network test by interacting with the base station) Module) control instructions, such as testing, starting the dial test, changing the dial test parameters, repeatedly returning specific information and other test instructions; and receiving and presenting the network quality parameter information (that is, the test result) fed back by the dial test module. Specifically, the control device 301 and the transmission device 302 can be connected by using an existing transmission DCN (data communication network), and control information can be exchanged by using an out-of-band (independent data network, generally using the TCP/IP protocol) information transfer method (such as test instructions, control instructions to the base station, etc.), for example, the control device 301 transmits information with the transmission device 302 through the Ethernet interface. The transmission devices 302 may forward the test instructions in an in-band (transmission overhead byte of service channel) information transmission manner. Specifically, when the transmission equipment 302 transmits the test command through the transmission overhead byte, the DCC (data communication channel) of SDH itself can be used. Generally, three bytes D1, D2, and D3 can be selected to forward the test command, that is, in D1 , D2, D3 three bytes carry test instruction information; when the transmission equipment 302 transmits the test instruction through the transmission overhead byte, it can also use the reserved byte in the transmission overhead byte to transfer, for example, D4～D12, Reserved bytes for transmitting test commands can be defined.

In the prior art, the transmission device 302 is mainly used as a carrier for information transfer between different regions. For example, the intercommunication information between base stations that are far apart must rely on the transmission device in the transmission network for transmission. In the embodiment of the present invention, by integrating the dialing test module in the transmission device 302, not only can the test results obtained through interaction with the base station be obtained, but also the control information and the obtained test results can be exchanged with the control device 301 through the transmission network to complete command receiving, dialing functions such as measuring and sending feedback information.

The base station 303 serves as the dial-up test object, and cooperates with the dial-up test module in the transmission device 302 to complete corresponding tests. The base station 303 and the dial test module in the transmission device 302 may be connected through an air interface. When the dial test module initiates an operation, the base station 303 needs to respond accordingly to this operation.

Through the wireless network test system provided in Embodiment 1 of the present invention, the control device 301 sends test instructions to each transmission device 302 distributed in the transmission network 1, and the transmission device 302 that receives the test instruction interacts with the base station 303 to test the wireless network. The performance of the network 2, and feed back the test results to the control device 301 through the transmission network 1. With this technical solution, test instructions can be transmitted in real time through the transmission network without the intervention of test personnel, thereby improving the real-time performance of wireless network testing; on the other hand, the test results are fed back through the transmission network, independent of wireless networks, Therefore, the test result can more objectively reflect the performance of the wireless network under test, thereby improving the accuracy of the obtained test result of the wireless network.

Step 501, the control device sends a test instruction to the transmission devices distributed in the transmission network.

Step 502, the transmission device receives the test instruction sent by the control device, and sends test information to the base station through the wireless network under test according to the test instruction.

Step 503, the transmission device determines the test result of the wireless network under test according to the feedback from the base station.

Step 504, the transmission device sends the determined test result to the control device through the transmission network.

Through the above process, the test command is sent through the transmission network, thereby ensuring the timeliness of testing the wireless network, and the feedback of the test result is passed through the transmission network, thereby improving the accuracy of the test result.

In the preferred implementation mode provided by Embodiment 2 of the present invention, before performing the above step 501, that is, before the transmission device sends a test command to the transmission devices distributed in the transmission network, the transmission device can detect the Whether the transmission device is in a normal working state, and send the test command to the dial test module in the normal working transmission device for testing. Specifically, the transmission device can determine whether the transmission device is in a normal working state through ID positioning or polling. For example, information is regularly sent to each transmission device, and if a feedback on the information is received from the transmission device, it is determined that the transmission device is in a normal working state; otherwise, it is determined that the transmission device is in an abnormal working state.

In the preferred implementation mode provided by Embodiment 2 of the present invention, the specific execution process of step 502 of the flow shown in Figure 5, that is, the process in which the transmission device sends test information to the base station through the wireless network under test according to the received test instruction, as shown in Figure 6 shown, including the following steps:

Step 601 , the transmission device receiving the test instruction determines whether it meets the processing conditions for the test instruction, if yes, execute step 602 , if not, execute step 603 .

Step 602, the transmission device sends test information to the base station through the wireless network under test.

Step 603, the transmission device forwards the test instruction to transmission devices distributed in the transmission network that meet the processing conditions for the test instruction.

Through the process shown in Figure 6, when the transmission network includes multiple transmission devices, the optimal transmission device can be assigned to the wireless network under test to perform the test process, that is, for different wireless networks under test, different transmission devices are assigned to perform the test process .

In the preferred implementation mode provided by Embodiment 2 of the present invention, the execution process of the above step 601, that is, the process for the transmission device receiving the test command to determine whether it meets the processing conditions for the test command, as shown in Figure 7, includes the following steps :

Step 701 , the transmission device receiving the test instruction judges whether its own identification matches the identification carried in the test instruction, if yes, execute step 702 , if not, execute step 703 .

Step 702 , determine that it meets the processing conditions for the test instruction.

Step 703 , determine that it does not meet the processing conditions for the test instruction.

Specifically, after the control device determines the transmission device used for testing, it can carry the identification corresponding to the transmission device in the test instruction, and send the test instruction to the transmission equipment distributed in the transmission network; correspondingly, the transmission device After receiving the test command, judge whether the self-identity matches the test command. The device forwards the test instruction to other transmission devices in the transmission network. Specifically, when the transmission device forwards the test instruction, it can forward the test instruction to any transmission device in the transmission network that has a connection relationship with itself, or forward it according to the identifier included in the test instruction, that is, according to the test instruction carried in the test instruction. identify, and forward the test instruction to the transmission equipment distributed in the transmission network that meets the processing conditions for the test instruction.

In the second embodiment of the present invention, the reserved and unused transmission overhead bytes stipulated by the SDH transmission technology are used to realize the information transmission between transmission devices (such as the forwarding of test instructions), specifically, some of the bytes can be customized for control Carriers of information (such as test instructions, control information to the base station), such as F1, F2, X2, etc., can also directly use unused reserved transmission overhead bytes, such as D4-D12 bytes of the ECC channel to transmit control information to The wireless dial test module can also use the used transmission overhead bytes in the transmission network, such as D1, D2, D3.

The above is the preferred way of forwarding test instructions between transmission devices in Embodiment 2 of the present invention. In practical applications, the transmission overhead byte J1 of SDH can also be used to transmit the above information. The specific transmission format can preferably adopt text format or 16 Hexadecimal format.

Compared with the prior art, the technical solution provided by Embodiment 2 of the present invention does not require the support of the wireless network for the transmission of test instructions and the feedback of test results, that is, it can truly separate from the wireless network and use the transmission network to perform remote wireless dialing test control. The existing dial test terminal function is carried by the transmission equipment in the transmission network (that is, the dial test module is integrated in the transmission equipment). The entire dial test process does not depend on the wireless network environment, and only needs to be completed in a single transmission network. Test of wireless network.
