The one or more instrumented substrates include one or more sensors. When the one or more sealable containers transport the one or more instrumented substrates through the semiconductor factory, the one or more sensors measure one or more conditions of the one or more instrumented substrates. The one or more sealable containers also receive sensor data from the one or more sensors contained on the one or more instrumented substrates.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to provide a method and system for collecting industrial big data in semiconductor factories, which can overcome the shortcomings of the prior art.

[0006] To achieve the above objectives, the present invention provides a method for collecting industrial big data in semiconductor factories, characterized in that the method includes the following steps:

[0007] Industrial big data information is collected from mobile terminals;

[0008] The mobile terminal listens to the primary synchronization signal and the secondary synchronization signal sent by the base station.

[0009] In response to detecting the primary synchronization signal and the secondary synchronization signal sent by the base station, the mobile terminal determines the first signal strength of the primary synchronization signal and the second signal strength of the secondary synchronization signal.

[0010] The mobile terminal determines whether the absolute value of the difference between the first signal strength and the second signal strength is greater than a signal difference threshold, wherein the signal difference threshold is indicated in the system information;

[0011] If the absolute value of the difference between the first signal strength and the second signal strength is greater than the signal difference threshold, the mobile terminal sends a first random access preamble to the base station on the PRACH resource, and at the same time sends a random access request and a scheduling request to the base station on the first PUSCH resource. There is a first mapping relationship between the PRACH resource used to send the first random access preamble and the first PUSCH resource, and the first mapping relationship is indicated in the system information.

[0012] If the absolute value of the difference between the first signal strength and the second signal strength is less than the signal difference threshold, the mobile terminal sends a first random access preamble to the base station on the PRACH resource, and at the same time sends a random access request and a scheduling request to the base station on the second PUSCH resource. There is a second mapping relationship between the PRACH resource used to send the first random access preamble and the second PUSCH resource, which is indicated in the system information.

[0013] In response to receiving the first random access preamble, the base station attempts to receive the random access request and scheduling request sent by the mobile terminal on the first PUSCH resource based on the first mapping relationship;

[0015] In a preferred embodiment, the method for collecting industrial big data for semiconductor factories includes the following steps:

[0016] If a random access request and a scheduling request sent by a mobile terminal are received on the first PUSCH resource, the base station sends a first downlink control message to the mobile terminal on the PDCCH channel, wherein the first downlink control message is repeated at least 4 times.

[0017] If a random access request and a scheduling request sent by a mobile terminal are received on the second PUSCH resource, the base station sends a second downlink control message to the mobile terminal on the PDCCH channel, wherein the second downlink control message is sent at least twice.

[0018] In response to receiving a first downlink control message, the mobile terminal listens for a first PDSCH message sent by the base station on the downlink resources indicated by the first downlink control message. The first PDSCH message includes a C-RNTI, a timing advance value, and an uplink grant. The first PDSCH message is sent at least four times.

[0098] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0099] Unless otherwise expressly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "comprises" shall be understood to include the stated elements or components without excluding other elements or other components.

[0100] Figure 1 This is a schematic diagram of the system structure according to an embodiment of the present invention.

[0101] Figure 2 This is a flowchart of a method according to an embodiment of the present invention. As shown in the figure, the method of the present invention includes the following steps:

[0102] Step 101: Collect industrial big data information using mobile terminals;

[0103] Step 102: The mobile terminal listens to the primary synchronization signal and secondary synchronization signal sent by the base station;

[0104] Step 103: In response to detecting the primary synchronization signal and the secondary synchronization signal sent by the base station, the mobile terminal determines the first signal strength of the primary synchronization signal and the second signal strength of the secondary synchronization signal; those skilled in the art should understand that the signal strength can be expressed using metrics such as RSRP and RSRQ;

[0105] Step 104: The mobile terminal determines whether the absolute value of the difference between the first signal strength and the second signal strength is greater than the signal difference threshold, wherein the signal difference threshold is indicated in the system information;

[0106] Step 105: If the absolute value of the difference between the first signal strength and the second signal strength is greater than the signal difference threshold, the mobile terminal sends a first random access preamble to the base station on the PRACH resource, and the mobile terminal simultaneously sends a random access request and a scheduling request to the base station on the first PUSCH resource. There is a first mapping relationship between the PRACH resource used to send the first random access preamble and the first PUSCH resource, and the first mapping relationship is indicated in the system information.

[0107] Step 106: If the absolute value of the difference between the first signal strength and the second signal strength is less than the signal difference threshold, the mobile terminal sends a first random access preamble to the base station on the PRACH resource, and at the same time sends a random access request and a scheduling request to the base station on the second PUSCH resource. There is a second mapping relationship between the PRACH resource used to send the first random access preamble and the second PUSCH resource, and the second mapping relationship is indicated in the system information.

[0108] Step 107: In response to receiving the first random access preamble, the base station attempts to receive the random access request and scheduling request sent by the mobile terminal on the first PUSCH resource based on the first mapping relationship;

[0109] Step 108: In response to receiving the first random access preamble, the base station attempts to receive the random access request and scheduling request sent by the mobile terminal on the second PUSCH resource based on the second mapping relationship.

[0110] In a preferred embodiment, the method for collecting industrial big data for semiconductor factories includes the following steps:

[0111] If a random access request and a scheduling request sent by a mobile terminal are received on the first PUSCH resource, the base station sends a first downlink control message to the mobile terminal on the PDCCH channel, wherein the first downlink control message is repeated at least four times. In one embodiment, if a random access request and a scheduling request sent by a mobile terminal are received on the first PUSCH resource, the base station can confirm that the first mapping relationship is used, thereby determining that the absolute value of the difference between the first signal strength and the second signal strength is greater than the signal difference threshold. Those skilled in the art should understand that the absolute value of the difference between the first signal strength and the second signal strength being greater than the signal difference threshold may be due to excessive random jitter of the channel over time, a situation that is more serious in 5G short-wavelength communication.

[0112] Those skilled in the art should understand that downlink control messages have several aggregation levels, such as 1, 2, 4, and 8, and the corresponding downlink control messages can have several repetitions, such as 1, 2, 4, and 8.
