Detailed Description
In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.
Aiming at the problems that the signal intensity in the shielding space cannot be ensured in real time by means of manual adjustment and the manual adjustment error is large in the prior art, the invention provides a method and a device for adjusting the signal intensity.
As shown in fig. 1, an embodiment of the present invention provides a method for adjusting signal strength, including:
and step 12, establishing an adjusting instruction aiming at the signal intensity in the shielded space according to the real-time signal intensity of the terminal to be detected, and sending the adjusting instruction to a network side, so that the network side can adjust the signal intensity in the shielded space according to the adjusting instruction.
In the above embodiment of the present invention, the real-time signal intensity in the shielding space is, in a broad sense, equal to the real-time signal intensity of the terminal to be tested in the shielding space; however, in a strict sense, the two are not equal, and the real-time signal intensity of the terminal to be tested is affected by factors such as the signal receiving capability of the terminal to be tested, the operating state of the terminal to be tested, and the real-time load of the terminal to be tested, besides the real-time signal intensity in the shielded space. And then, in step 12, an adjusting instruction for the signal strength in the shielded space is constructed according to the real-time signal strength of the terminal to be tested, where the adjusting instruction is generally a control command for increasing or decreasing the signal strength.
The specific entity of the network side can be a network environment control module in the shielded space, and the network environment control module adjusts the signal intensity in the shielded space according to the adjustment instruction; or the entity can also be a network management system at the network base station side, and the network management system at the base station side directly adjusts the emission intensity of the radio frequency signal, thereby achieving the purpose of adjusting the signal intensity in the shielding space.
The embodiment of the invention adjusts the signal intensity in the shielding space in real time according to the real-time signal intensity of the terminal to be tested, is suitable for scenes needing long-time testing, and ensures the accuracy and timeliness of signal intensity adjustment.
Further, in the foregoing embodiment of the present invention, step 11 specifically includes:
and step 111, receiving the real-time signal strength reported by the terminal to be tested in a shielded space through the USB interface of the terminal to be tested. Namely, the embodiment of the invention realizes the control of the terminal through the USB interface of the terminal, thereby acquiring the signal intensity of the signal received by the terminal.
Furthermore, when the concrete entity of the network side is a network environment control module in a shielded space, the network environment control module is composed of an adjustable attenuator; specifically, step 12 includes:
and 121, sending the adjusting instruction to an adjustable attenuator on the network side, and adjusting the signal intensity in the shielding space by the adjustable attenuator through adjusting the attenuation value of the adjustable attenuator.
Further, the automatic calibration scheme of the embodiment of the present invention regarding the signal strength is as follows, that is, step 12 specifically includes:
step 122, obtaining an average value of a plurality of real-time signal intensities of the terminal to be detected within a preset time period;
the reporting period of the signal intensity of the terminal to be tested can be preset in a program, for example, can be set to 1s, the real-time can be basically achieved, the preset time period can be set to 5min, that is, all real-time signal intensities of the terminal to be tested which are obtained within 5min are averaged, and the signal intensity is changed in real time, and the size fluctuation of the signal intensity within a period of time can be better reflected by adopting an averaging method.
Step 123, comparing the average value with a preset intensity value to obtain a difference value between the average value and the preset intensity value; the method for comparing the average value with the preset intensity value reduces the real-time comparison times to a certain extent and improves the efficiency.
Step 124, if the difference value is within a preset range, the signal intensity in the shielding space does not need to be adjusted; otherwise, constructing an adjusting instruction for controlling the signal intensity in the shielding space to rise or fall. Theoretically, when the difference is equal to 0, the signal strength in the mask space does not need to be adjusted; however, in general, the average value and the preset intensity value do not need to be completely equal, so a preset range is preset, when the difference value exceeds the preset range, an adjustment instruction for controlling the signal intensity to rise or fall is constructed, and the specific value of the difference value determines the adjustment amplitude and the rise or fall.
Specifically, in the foregoing embodiment of the present invention, step 124 specifically includes:
step 1241, if the difference exceeds the preset range and the difference is a positive value, constructing an adjustment instruction for controlling the signal intensity reduction in the shielding space;
and 1242, if the difference exceeds the preset range and the difference is a negative value, constructing an adjustment instruction for controlling the signal intensity in the shielding space to rise.
In order to ensure accurate sending, receiving and executing of the adjustment instruction, the embodiment of the invention further provides that two pairs of message primitives are utilized to carry out the real-time signal strength reporting and the specific communication of sending the adjustment instruction; that is, in the embodiment of the present invention, the step 11 described in terms of information interaction specifically includes: a
Step 112, receiving a report message primitive sent by a terminal to be tested in a shielded space, wherein the report message primitive comprises the real-time signal intensity of the terminal to be tested and a report message primitive serial number; and the sequence numbers of the reported message primitives in the continuous reported message primitives sent by the terminal to be tested are continuous integers.
Specifically, the structure of the primitive of the reported message is shown in fig. 2, and the primitive mainly includes a primitive type and a serial number of the reported message primitive, wherein the primitive type field is used for filling the real-time signal strength of the terminal to be tested; secondly, in order to more clearly identify the real-time signal strength of the terminal, the report message primitive also comprises a time information field which is used for filling the specific time of the terminal reporting the corresponding signal strength and can be represented by a form of year-month-day-hour-minute-second; the further report message primitive may further include a network information field, where the network information field is used to identify information such as a network type, a cell name, and a signal strength of the corresponding terminal to be tested. The sequence number of the reported message primitive is a cyclic sequence which can be set to be increased within the range of 0-127, and the sequence numbers of the reported message primitives in the continuous reported message primitives are continuous integers when the terminal to be tested sends the reported message primitives.
Based on the principle of a general message system, in order to know whether a message sent by the receiver is correctly received by another party in time, the receiver needs to return a response message aiming at the message after receiving the message sent by the sender, so that the sender can know whether the message is successfully or unsuccessfully sent, whether the message needs to be retransmitted or not in real time. Accordingly, in the above embodiment of the present invention, after step 112, the adjusting method further includes:
step 113, responding the report message primitive to feed back a first confirmation message primitive to the terminal to be tested; wherein the first acknowledgement message primitive comprises: confirming state and confirmed primitive sequence number of report message; wherein the content of the first and second substances,
the acknowledgement status includes: and confirming that the ACK state of the reported message primitive is correctly received and receiving the NACK state of the reported message primitive abnormity.

It should be noted that, when the first acknowledgement message primitive is used to acknowledge other primitive messages, the acknowledgement object field therein may be filled with primitive type information corresponding to other primitive messages.
Specifically, when the serial number of the reported message primitive reported by the continuous terminal to be tested is correctly received, the ACK message is replied, which indicates that the reported message primitive is continuously and correctly received; if receiving discontinuous report, it shows that the discontinuous part is lost, at this moment, it sends NACK information to the lost specific sequence number; if the primitive of the report message can not be received continuously, the loss or other abnormality is also shown, and the NACK information should be replied at this time.
Continuing with the above example, the step of sending the adjustment instruction in step 12 in the embodiment of the present invention includes:
step 125, sending the adjustment command to the network side by using the primitive of the adjustment command;
wherein the adjustment command primitive comprises: adjusting mode, adjusting step length and adjusting command primitive sequence number; the adjusting mode comprises ascending, descending or stopping; wherein the content of the first and second substances,
primitive serial numbers of the adjusting commands corresponding to the continuous uplink or descending adjusting modes are continuous integers, and the adjusting command corresponding to the stopped adjusting mode is a preset value.
Specifically, the structure of the primitive of the adjustment command is shown in fig. 4, which mainly includes an adjustment mode, an adjustment step size, and a serial number of the primitive of the adjustment command, wherein the adjustment mode and the adjustment step size are determined according to the difference, the positive and negative of the difference determine the adjustment mode, and the absolute value of the difference determines the adjustment step size; in order to more clearly identify the adjustment command primitive, the adjustment command primitive further includes a primitive type field, and the primitive type field identifies the primitive as an adjustment command; an adjustment interval field for identifying an adjustment interval in its adjustment process. Its justification command primitive sequence number is also a circular sequence and may also be set to increment in the range of 0-127. When the adjustment mode is ascending or descending, the adjustment step length and the adjustment time interval are effective, and the signal intensity is adjusted according to the adjustment step length and the adjustment time interval; when the adjustment mode is stop, the adjustment step length and the adjustment time interval are both invalid.
Similarly, in the above embodiments of the present invention, after step 125, the adjusting method further includes:
step 126, receiving a second confirmation message primitive returned by the network side according to the adjustment command primitive; wherein the content of the first and second substances,
the second confirmation message primitive includes a confirmation status and a confirmed adjustment command primitive sequence number; wherein the content of the first and second substances,
the acknowledgement status includes: confirming correct reception of the ACK status of the adjustment command primitive and receiving an abnormal NACK status of the adjustment command primitive.
That is, after receiving the primitive of the adjustment command sent by the network side, a second primitive of the acknowledgement message needs to be returned, the structure of the second primitive of the acknowledgement message is shown in fig. 5, which mainly includes an acknowledgement status and a sequence number of the confirmed primitive of the adjustment command, wherein, a field of the acknowledgement status is used for filling an ACK message or a NACK message for the reception situation of the primitive of the adjustment command; further, in order to more clearly identify the confirmation condition of the second confirmation message primitive to the adjustment command primitive, the second confirmation message primitive further includes a primitive type field, and the field is used for filling the confirmation as the terminal confirmation; and a validation object field for identifying the primitive type validated by the validation object field, specifically the network adjustment command in the invention. It should be noted that, when the second confirmation message primitive is used to confirm other primitive messages, the confirmation object field therein may be filled with primitive type information corresponding to other primitive messages.
In summary, the method for adjusting signal strength provided by the embodiment of the invention can collect the wireless signal strength of the terminal to be measured in real time, and adjust the strength of the wireless signal in the shielded space according to the preset fluctuation range of the wireless signal, thereby avoiding the introduction of time delay of artificial observation and solving the accuracy and timeliness of adjustment; meanwhile, two pairs of message primitives are utilized for communication, so that accurate sending, receiving and execution of the adjusting instruction are ensured.

Specifically, in the foregoing embodiment of the present invention, the receiving module 61 specifically includes: a
The system comprises a message primitive receiving module, a message primitive processing module and a message primitive processing module, wherein the message primitive receiving module is used for receiving a reporting message primitive sent by a terminal to be tested in a shielded space, and the reporting message primitive comprises the real-time signal intensity of the terminal to be tested and a reporting message primitive serial number; and the sequence numbers of the reported message primitives in the continuous reported message primitives sent by the terminal to be tested are continuous integers.
Specifically, in the above embodiment of the present invention, the adjusting device further includes:
the first response module is used for responding the reporting message primitive to feed back a first confirmation message primitive to the terminal to be tested after receiving the reporting message primitive sent by the terminal to be tested in a shielded space; wherein the first acknowledgement message primitive comprises: confirming state and confirmed primitive sequence number of report message; wherein the content of the first and second substances,

Specifically, in the above embodiment of the present invention, the adjusting module further includes:

Specifically, the adjusting method provided by the above embodiment of the present invention is applied to a system, where the system includes an adjusting device for signal strength, a shielding space, a terminal to be tested in the shielding space, a network environment control module in the shielding space, and a network base station, and a basic architecture of the system is shown in fig. 7.
The invention aims to provide an automatic signal calibration method in a shielding space, which is characterized in that the intensity of a signal in a shielding box is uploaded to an adjusting device in real time, and the adjusting device starts a calibration strategy according to the intensity of the signal and controls the shielding space to adjust an adjustable attenuator so that a terminal to be tested obtains proper signal intensity.
Specifically, the terminal signal strength reporting primitive is sent by the terminal to be tested and is responsible for reporting information related to the network strength at a certain moment to the adjusting device, and the adjusting device needs to respond by using the network confirmation primitive after receiving the report. If the continuous primitive serial numbers reported by the terminal are correctly received, the adjusting device replies ACK, which indicates that the reported primitives are continuously and correctly received. If discontinuous report is received, it indicates that the discontinuous part is lost, and at this time, the adjusting device should send NACK for the lost specific sequence. If the report cannot be received continuously, it indicates that there is a loss or other abnormality, and at this time, the adjusting device should also reply NACK, but the sequence number of the corresponding confirmed primitive should be set to a special value. The primitive sequence number is a cyclic sequence and is increased within the range of 0-127. The terminal judges whether to continue sending the reporting primitive according to the receiving condition of the NACK, and the judgment can be the duration of the NACK or the occurrence frequency of the NACK. The adjusting device determines whether to continue issuing the network confirmation primitive and the adjusting instruction or not through the duration and the times of replying the NACK.
The network adjusting command primitive is sent by the adjusting device and is responsible for sending an adjusting command to the network side; the second confirmation message primitive is responsible for performing a correctness check on the receipt of the adjustment instruction. When the adjustment command sent by the adjustment device is ascending/descending, the adjustment step length and the adjustment interval field are valid, and the network side should execute adjustment operation according to the configuration to achieve the target of calibration adjustment. When this command is stop, the step size and interval are invalid and the sequence number should be set to a special value (e.g., 255). When the terminal correctly and continuously receives the adjustment command, a terminal confirmation primitive needs to be sent, and the confirmation state is ACK. If a sequence number discontinuity occurs (and the sequence number is not a value of a particular meaning, e.g., 255), or no adjustment command is received for a long time, a NACK is sent. The software management station and the network environment control module can decide whether to continue sending the adjustment command and the confirmation primitive according to the duration and the times of the NACK duration.
Then when the adjusting device finds that the detection intensity of the terminal to be detected reaches the standard, the network environment control unit is controlled to stop adjusting through the stop command, at the moment, the network adjusting command primitive and the network adjusting confirmation primitive stop sending, and the serial number returns to zero; and after the adjustment is finished, the software management station informs the terminal to be tested, the reporting of the terminal signal strength is stopped, and the calibration is finished.
It should be noted that, the signal strength adjusting apparatus provided in the above embodiments of the present invention is an adjusting apparatus applying the signal strength adjusting method, and all embodiments of the signal strength adjusting method are applicable to the adjusting apparatus and can achieve the same or similar beneficial effects.

An identified module of executable code may, for instance, comprise one or more physical or logical blocks of computer instructions which may, for instance, be constructed as an object, procedure, or function.
