Referring to fig. 1, fig. 1 is a schematic structural diagram of a molding system according to an embodiment of the present application. The modeling system may include, but is not limited to, one or more modeling receiving terminals, one or more modeling sending terminals, for example, in fig. 1, a modeling receiving terminal 2, a modeling receiving terminal 3, a modeling receiving terminal 4, a modeling sending terminal 5, and a central control software, where the modeling sending terminal 5 may establish a wireless link with the modeling receiving terminal 1 to perform communication, the modeling sending terminal 5 may also establish a wireless link with the modeling receiving terminal 2 to perform communication, the modeling sending terminal 5 may also establish a wireless link with the modeling receiving terminal 3 to perform communication, and the modeling sending terminal 5 may also establish a wireless link with the modeling receiving terminal 4 to perform communication. The central control software is responsible for collecting the information of the modular testing terminals of different testing points (for example, collecting the measurement information of different modular testing receiving terminals and the configuration information transmitted by the modular testing transmitting terminal), intelligently analyzing the collected information by the central control software to obtain an analysis result, and outputting the net-rule net-optimizing suggestion according to the analysis result. The analog testing system shown in fig. 1 includes, but is not limited to, an analog testing receiving terminal, a central control software and an analog testing transmitting terminal, and may also include other communication devices, where the number and the form of the devices shown in fig. 1 are used as examples and are not limited to the embodiments of the present application.

In the embodiment of the application, the analog testing transmitting terminal represents a network gauge network optimal quasi-selected station, provides a signal source required by analog testing for the analog testing system, and is the core of the whole analog testing system. The modular test transmitting terminal needs to have the characteristic of portability and can be realized by terminal equipment of the existing communication system. A Mobile Station may refer to various forms of User Equipment (UE), access terminals, subscriber units, subscriber stations, mobile Stations (MSs), remote stations, remote terminals, mobile devices, user terminals, wireless communication devices, user agents, or User Equipment.

In an alternative embodiment, the form structure of the die test transmitting terminal is shown in fig. 2, and as shown in fig. 2, the die test transmitting terminal may be composed of a smart terminal and a mushroom antenna. The intelligent terminal can use an internet of things chip platform (for example, chun teng UIS8910 DM) which is connected with the remote mushroom antenna through a radio frequency cable. The relevant parameters of the modular test receiving terminal are configured by means of an AT (an instruction set) instruction set.

In the embodiment of the application, the analog detection receiving terminal can sweep the current network signal and also can scan the signal of the analog transmitting terminal equipment to provide the measurement information of the covered area. In addition, the module detection receiving terminal also has the characteristic of portability, and can be terminal equipment similar to the module detection transmitting terminal, and the description is omitted herein. For example, the modular test receiving terminal is in a conventional terminal equipment form, and can directly use an internet of things chip platform (for example, chun teng UIS8910 DM).

In an alternative embodiment, as shown in fig. 3a, the deployment scenario of the analog measurement system illustrated in fig. 1 may be that the analog measurement transmitting terminal and the analog measurement receiving terminal need to synchronize to the current network cell, the analog measurement transmitting terminal 5 synchronizes to the current network cell and designates a transmitting cell signal, or synchronize to the designated analog measurement cell and designate a transmitting cell signal. The die measurement receiving terminal 1, the die measurement receiving terminal 2, the die measurement receiving terminal 3 and the die measurement receiving terminal 4 are synchronized to the current network cell or the appointed die measurement cell, and the current network cell and the appointed cell are measured.

In another alternative embodiment, as shown in fig. 3b, the deployment scenario of the analog measurement system shown in fig. 1 may be that the analog measurement terminal is "independently networked", and the analog measurement sending terminal 5 is in a coverage loss state and works as an isolated station to directly send the public signal and the system information to the designated cell. If a plurality of module testing transmitting terminals exist in the module testing system, the module testing transmitting terminal #1 started at first is in a lost coverage state, and the module testing transmitting terminal # 2 started later and the module testing transmitting terminal N# are synchronized to the module testing transmitting terminal #1 according to the network searching result started or work as an isolated station. The module test receiving terminal 1, the module test receiving terminal 2, the module test receiving terminal 3 and the module test receiving terminal 4 measure cells according to the system information and the monitored cell list.

In an alternative embodiment, after the modeling system shown in fig. 1 is deployed according to the deployment scenario shown in fig. 3a or fig. 3b, the modeling sending terminal 5 periodically and circularly sends a common signal to the modeling receiving terminal 1, the modeling receiving terminal 2, the modeling receiving terminal 3 and the modeling receiving terminal 4, the modeling receiving terminal 1 completes residence of a serving cell or performs periodic measurement and reporting on the serving cell and the neighboring cell according to the received common signal, the modeling receiving terminal 2 completes residence of the serving cell or performs periodic measurement and reporting on the serving cell and the neighboring cell according to the received common signal, the modeling receiving terminal 3 completes residence of the serving cell or performs periodic measurement and reporting on the serving cell and the neighboring cell according to the received common signal, and the modeling receiving terminal 4 completes residence of the serving cell or performs periodic measurement and reporting on the serving cell and the neighboring cell. The power consumption of the analog measurement transmitting terminal 5 is necessarily increased due to the fact that the analog measurement transmitting terminal 5 circularly transmits a plurality of signals for a long time, and the duration of the analog measurement transmitting terminal 5 is affected.

The application provides a signal transmission method which can be applied to a modular test system shown in fig. 1. When the analog measurement receiving terminal is not required to measure the neighbor cells, the analog measurement transmitting terminal 5 does not transmit the system information (System Information Block, SIB) of the service cell to the analog measurement receiving terminal, and informs the analog measurement receiving terminal of the resident cell through a main information block (Master Information Block, MIB) carrying message, and the analog measurement receiving terminal measures the signal of the analog measurement transmitting terminal by using a preset paging period. The power consumption of the analog measurement transmitting terminal is reduced, and the endurance time of the analog measurement transmitting terminal in the network gauge optimization is improved.

Referring to fig. 4, fig. 4 is a flowchart of a signal transmission method according to an embodiment of the present application, where the signal transmission method can be applied to the analog measurement system shown in fig. 4, and the signal transmission method is described from the perspective of interaction between the analog measurement receiving terminal and the analog measurement transmitting terminal. The signal transmission method comprises the following steps:

s401, the module testing sending terminal determines the current module testing scene requirement.

The requirement of the mode measurement scene can be that a service cell is measured, and the service cell is periodically measured and a measurement result is reported; the module measurement scene requirement can also be to measure the service cell and the adjacent cell, and periodically measure and report the measurement result to the service cell and the adjacent cell. The neighbor cell may be the same-frequency neighbor cell of the serving cell, or may be a different-frequency neighbor cell of the serving cell, or may be the same-frequency neighbor cell and the different-frequency neighbor cell of the serving cell.

S402, the module testing transmitting terminal transmits a first downlink public signal according to the module testing scene requirement; correspondingly, the analog detection receiving terminal receives the first downlink public signal.

The reserved field in the MIB in the first downlink common signal is used to indicate whether the first downlink common signal includes system information of a serving cell. That is, according to the requirement of the analog measurement scene, the transmission of signals unnecessary for the resident cell can be reduced, and the endurance time of the analog measurement transmitting terminal in the network gauge network is improved.

In an alternative embodiment, when the modulo measurement scenario requirement is to measure the serving cell, the reserved field in the MIB in the first downlink common signal indicates that the system information of the serving cell is not included in the first downlink common signal. It may be that when the reserved field in the MIB indicates the first value, system information of the serving cell is not included in the first downlink common signal. Wherein, the system information of the serving cell may include SIB1-SIB5. Since frequency point information, cell list information, etc. in the system information of the serving cell are not required when the neighbor cell is not required to be measured, the system information of the serving cell may not be transmitted. When the reserved field in the MIB in the first downlink common signal indicates that the system information of the serving cell is not included in the first downlink common signal, the primary synchronization signal (Primary Synchronization Signal, PSS), the secondary synchronization signal (Secondary Synchronization Signal, SSS), the cell reference signal (Cell Reference Signal, CRS) and the MIB may be included in the first downlink common signal. As shown in fig. 5, the MIB includes downlink Bandwidth (dl-Link Bandwidth), physical hybrid automatic repeat request indicator channel (Physical Hybrid ARQ Indicator Channel, PHICH) configuration parameters (ph-Config), system frame number (System Frame Number, SFN), scheduling information of SIB1, and reserved field (spare). For example, the spark has 5 bits, let the 5 bits in the spark be all 1, that is 11111, at this time, the first value indicated by the spark is 31, and the first value 31 indicates that the system information of the serving cell is not included in the first downlink common signal, that is, when the spark is set to the first value 31 in the MIB, SIB1-SIB5 is not included in the first downlink common signal sent by the modestly sending terminal.

In another alternative embodiment, when the modulo measurement scenario requirement is to measure the serving cell and the neighbor cell, the reserved field in the MIB in the first downlink common signal indicates that the system information of the serving cell is included in the first downlink common signal. It may be that when the reserved field in the MIB indicates the second value, system information of the serving cell is included in the first downlink common signal. At this time, PSS, SSS, CRS, MIB and SIB1-SIB5 may be included in the first downlink common signal. For example, the spark has 5 bits, let 5 bits in the spark be all 0, that is 00000, at this time, the second value indicated by the spark is 0, where the second value 0 indicates that the first downlink common signal includes system information of the serving cell, that is, when the spark in the MIB is set to be the second value 0, SIB1-SIB5 is included in the first downlink common signal sent by the modestly sending terminal.

In an alternative embodiment, the modulo transmitting terminal sets the transmission period of the CRS and MIB in the first downlink common signal to 20ms, and transmits the CRS and MIB only in subframe #0 of the radio frame satisfying SFN mod2=0. That is, the modular test transmitting terminal increases the transmission period of the CRS and the MIB, and does not retransmit the CRS and the MIB when transmitting the CRS and the MIB in the transmission period of the CRS and the MIB, so that the number of times of transmitting the CRS and the MIB can be reduced in a certain time, and the data transmission amount of the modular test transmitting terminal can be reduced, so that the working time of the modular test transmitting terminal can be reduced, the power consumption of the modular test transmitting terminal can be reduced, and the endurance time of the modular test transmitting terminal in the network standard network optimization can be improved.

In an alternative embodiment, when the modeling scenario requirement is that the serving cell and the neighbor cell are measured, SIB1 is transmitted once in a transmission period of SIB1 in system information of the serving cell, and the transmission period may also be a scheduling period. That is, when the modulo receiving terminal is required to measure the serving cell and the neighbor cell, the modulo transmitting terminal does not perform retransmission transmission when transmitting SIB1 in the transmission period of SIB1, i.e., transmits SIB1 only in subframe #5 of the radio frame satisfying SFN mod8=0. The times of transmitting SIB1 can be reduced, and the data transmission quantity of the modular test transmitting terminal is reduced, so that the working time of the modular test transmitting terminal is reduced, the power consumption of the modular test transmitting terminal can be reduced, and the endurance time of the modular test transmitting terminal in the network gauge optimization is prolonged.

In an alternative embodiment, when the modeling scenario requirement is to measure the serving cell and the neighbor cell, the modeling transmitting terminal sets a transmission period of SIB2-SIB5 in system information of the serving cell to 80ms, that is, sets a system information window (System Information Window, SI-window) to 80ms. Each SIB is contained in only one system information (System Information, SI), each SI is associated with one SI-window, and the SI-windows of different SIs do not overlap each other, that is, SIB2-SIB5 can be transmitted within the SI-window. The length of the SI-window is the same for all SI and is configurable. Thus, the length of the SI-window may be set to 80ms, i.e. the scheduling periods of SIB2-SIB5 are all 80ms. And, SIB2-SIB5 is transmitted once in the transmission period of SIB2-SIB5, that is, SIB2-SIB5 is transmitted only once in subframe #0 of the first radio frame in SI-window, that is, SIB2-SIB5 is not retransmitted in SI-window. The times of transmitting SIB2-SIB5 can be reduced, and the data transmission amount of the modular test transmitting terminal is reduced, so that the working time of the modular test transmitting terminal is shortened, the power consumption of the modular test transmitting terminal can be reduced, and the endurance time of the modular test transmitting terminal in the network gauge network optimization is prolonged.

In an alternative embodiment, the modular receiving terminal determines whether the first downlink common signal includes the system information of the serving cell according to the reserved field in the MIB in the first downlink common signal. After receiving the MIB, the module measurement receiving terminal analyzes the MIB to obtain parameter information in the MIB, and at this time, the module measurement receiving terminal may obtain a value indicated by a spark in the MIB, determine whether to receive SIB1-SIB5 according to the value indicated by the spark, that is, determine whether the first downlink common signal includes system information of the serving cell according to the value indicated by the spark. The method may pre-negotiate to indicate that SIB1-SIB5 is not included in the first downlink common signal when the value indicated by the spark in the MIB is a first value, and indicate that SIB1-SIB5 is included in the first downlink common signal when the value indicated by the spark in the MIB is a second value, or indicate that SIB1-SIB5 is included in the first downlink common signal when the value indicated by the spark in the MIB is not the first value. When the analog detection receiving terminal receives the MIB, the information in the MIB is analyzed, a value indicated by the spark is obtained, when the spark indicates the first value, the system information of the serving cell is determined not to be included in the first downlink public signal, when the spark indicates the second value, the system information of the serving cell is determined to be included in the first downlink public signal, or when the spark does not indicate the first value, the system information of the serving cell is determined to be included in the first downlink public signal. Accordingly, the analog reception terminal may determine whether system information of the serving cell is included in the first downlink common signal according to the value indicated in the spark, that is, the analog reception terminal may determine whether to receive SIB1-SIB5 according to the value indicated in the spark. For example, it may be negotiated in advance that the analog receiving terminal determines that the system information of the serving cell is not included in the first downlink common signal when the spark indication is 31, that is, the analog receiving terminal does not receive SIB1-SIB5 when the spark indication is 31, and determines that the system information of the serving cell is included in the first downlink common signal when the spark indication is 0, that is, the analog receiving terminal receives SIB1-SIB5 when the spark indication is 0.

In an alternative embodiment, when the analog receiving terminal determines that SIB1-SIB5 is not received according to the spare indication first value in the MIB, that is, the analog receiving terminal determines that system information of the serving cell is not included in the first downlink common signal. At this time, the module test receiving terminal directly resides in the service cell and enters an idle mode, and periodically measures the service cell according to a preset paging period and reports a measurement result. In order to ensure that a measurement result with higher accuracy is obtained, the number of measurement times in a certain time is as large as possible, but the more the number of measurement times is, the higher the power consumption is, so that a relatively-compromise preset paging cycle can be selected in order to achieve both measurement accuracy and power consumption, that is, the preset paging cycle can be set to 640ms.

In an alternative embodiment, when the analog receiving terminal determines to receive SIB1-SIB5 according to the spark indication second value in the MIB, that is, the analog receiving terminal determines that the system information of the serving cell is included in the first downlink common signal. At this time, after receiving the MIB, the module measurement receiving terminal receives SIB1 according to the transmission period of SIB1, and then the module measurement receiving terminal obtains the scheduling information of SIB2-SIB5 by analyzing SIB1, and the module measurement receiving terminal receives SIB2-SIB5 according to the scheduling information of SIB2-SIB5, so as to complete cell residence. And then, the module measurement receiving terminal acquires the same-frequency adjacent cell information and different-frequency adjacent cell information of the service cell, enters an idle mode, determines a paging cycle according to the SIB2, and then periodically measures the service cell and the adjacent cell according to the paging cycle and reports a measurement result. In order to ensure that a measurement result with higher accuracy is obtained, the number of measurements in a certain period of time is as large as possible, but if the number of measurements is large, the power consumption is high, so that a more compromised paging cycle can be selected for both measurement accuracy and power consumption, that is, the paging cycle can be set to 640ms.

When the signal transmission method shown in fig. 4 is applied to the analog measurement system, the flow of the analog measurement transmitting terminal transmitting the first downlink common signal can be seen in fig. 6. As shown in fig. 6, when the analog measurement transmitting terminal transmits the first downlink common signal, the method may include the following steps S601 to S606:

If the receiving terminal needs to measure the neighbor cell, step S602 is executed, otherwise step S603 is executed.

S606, after PSS, SSS, CRS, MIB is transmitted according to the configured transmission period of PSS, SSS, CRS, MIB, SIB1-SIB5 is transmitted according to the configured transmission period of SIB1, SIB2, SIB3, SIB4, SIB5.

When the signal transmission method shown in fig. 4 is applied to the analog measurement system, the flow of the analog measurement receiving terminal receiving the first downlink common signal can be seen in fig. 7. As shown in fig. 7, the analog detection receiving terminal may include the following steps S701 to S710 when receiving the first downlink common signal:

s701, the receiving PSS/SSS completes cell synchronization.

S702, according to the sending period of the MIB, receiving the MIB and decoding the MIB.

S703, analyzing the information in the MIB to obtain the downlink bandwidth, PHICH configuration, SFN and SIB1 scheduling information.

S704, analyzing the reserved field in the MIB.

S705, determining whether the reserved field in the MIB indicates the first value.
