Description

Technical Field

[0001] The present invention relates to the technical field of Internet of Things, and in particular to a multi-material storage path planning method based on the Internet of Things. Background Art

[0002] Ambient IoT (A-IoT) is also called Ambient Power-enabled IoT Passive IoT (P-IoT), which means that some network nodes can be passive. They can obtain energy through solar energy, radio frequency, wind energy, water energy or tidal energy, and there is no restriction on the way of obtaining energy. These nodes are not equipped with or rely on power devices such as batteries, but obtain energy from the environment to support data perception, transmission and distributed computing. Nodes can also store the obtained energy. The passive IoT architecture can include passive terminals, readers and servers. Passive terminals can be in the form of tags or any other terminal forms without restriction. Readers can be access network devices, such as base stations, pole stations, micro base stations, macro stations, etc. Readers can also be terminal devices, such as mobile phones, IoT devices, handheld readers and writers, etc. The typical application scenario of A-IoT is warehouse / logistics. For example, in a storage scenario, by embedding or affixing passive or semi-passive IoT tags to goods, the goods are stored in warehouses, shopping malls, etc. During the logistics process, the goods-related information is automatically collected by the reader, that is, inventory or inventory, and the management personnel can quickly query the goods information in the system.

[0029] The technical solution of the present invention will be described below in conjunction with the accompanying drawings.

[0030] In the embodiment of the present invention, "indication" may include direct indication and indirect indication, and may also include explicit indication and implicit indication. The information indicated by a certain information is called information to be indicated. In the specific implementation process, there are many ways to indicate the information to be indicated, such as but not limited to, the information to be indicated can be directly indicated, such as the information to be indicated itself or the index of the information to be indicated. The information to be indicated can also be indirectly indicated by indicating other information, wherein there is an association relationship between the other information and the information to be indicated. It is also possible to indicate only a part of the information to be indicated, while the other parts of the information to be indicated are known or agreed in advance. For example, the indication of specific information can also be achieved by means of the arrangement order of each information agreed in advance (for example, specified by the protocol), thereby reducing the indication overhead to a certain extent. At the same time, the common parts of each information can also be identified and indicated uniformly to reduce the indication overhead caused by indicating the same information separately.

[0031] In addition, the specific indication method may also be various existing indication methods, such as but not limited to the above-mentioned indication methods and various combinations thereof. The specific details of the various indication methods can refer to the prior art and will not be repeated herein.

The type of memory can be any form of storage medium, which is not limited by the embodiments of the present invention.

[0034] The "protocol" involved in the embodiments of the present invention may refer to a protocol family in the communication field, a standard protocol with a similar protocol family frame structure, or a related protocol applied in future systems, and the embodiments of the present invention do not specifically limit this.

[0035] In the embodiments of the present invention, descriptions such as "when...", "in the case of...", "if" and "if" all mean that the device will perform corresponding processing under certain objective circumstances, but do not limit the time, nor do they require the device to perform judgment actions when implementing, nor do they mean the existence of other limitations.

[0039] like Figure 1 As shown, the IoT system may include: an ambient IoT management function (Ambient IoT management Function, AIoTMF), a reader and an AIoT device.

[0040] AIoTMF is used for business operations indicated by the application party, instructing the reader to perform AIoT-related operations, such as inventory, reading, and writing.

[0041] The reader can be a base station or a terminal. In the embodiment of the present application, the reader is a base station.

[0042] AIoT devices can be devices in the form of terminals, i.e., terminals. The terminal can be a terminal with transceiver functions, or a chip or chip system that can be set in the terminal. The terminal can also be called user equipment (UE), access terminal, subscriber unit, user station, mobile station (MS), mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication equipment, user agent or user device.

Alternatively, the terminal may also be customer-premises equipment (CPE).

[0043] Figure 2A flowchart of a method provided by an embodiment of the present invention. This multi-material storage path planning method based on the Internet of Things is applicable to the above-mentioned Internet of Things system, and involves the interaction between devices in the above-mentioned Internet of Things system. The specific process is as follows: S201, AIoTMF determines the storage areas of M types of AIoT devices respectively, and determines a total of N storage areas.

[0044] The device form of the AIoT device is a material device. For example, the AIoT device can be a label attached to the material device. M is an integer greater than 1, and N is an integer greater than or equal to 1. The M types of AIoT devices are AIoT devices of different forms, or the material devices attached to the AIoT devices are devices of different forms, such as different types of products, or different models of the same product.

[0045] Taking any one of the M types of AIoT devices as an example, AIoTMF can obtain the storage area of ​​the AIoT device during the inventory process, which is described in detail below.

[0046] Step S1: When the AIoTMF triggers the reader to take inventory of the designated area, the AIoTMF receives a request message from the reader.

[0047] The request message may include identification information, and the identification information may be information determined based on the device identification of the AIoT device and the identification of the terminal device.

[0048] The terminal device is a device that carries an AIoT device. It can be understood that the terminal device can be a device that transports the AIoT device. For example, in a logistics park scenario, the terminal device can transport the AIoT device to the storage where it needs to be stored in the logistics park. The terminal device can transport multiple AIoT devices, and the embodiment of this application is introduced by taking one of them as an example.

[0049] AIoT devices can be devices that are counted by the reader in a designated area. The designated area can be the entrance area of ​​a logistics park, that is, when the terminal device transports the AIoT device to the entrance area of ​​the logistics park, the AIoT device can be sensed by the network through the inventory. AIoT devices can be products with tags, such as electronic devices, materials, accessories, etc., without specific restrictions.

[0050] The device identification of an AIoT device can be used to uniquely identify the AIoT device. The identification type of the device identification of an AIoT device can be any of the following: an identification assigned to the AIoT device by the mobile communication network serving the AIoT device (such as a subscription permanent identifier (SUPI)), an identification assigned to the AIoT device by the manufacturer of the AIoT device (such as an electronic product code (EPC)), or an identification assigned to the AIoT device by the application party of the AIoT device (such as a user name / password, etc.).

[0051] For example, the frame structure of the device identification of the AIoT device includes the first information and the second information, and the first information and the second information can both contain multiple bits. In the frame structure, the second information is located after the first information. The first information can be the first 2 bits in the first byte (8 bits), and the last 6 bits in the byte are reserved. The first information can indicate the identification type of the device identification of the AIoT device through 4 values ​​of 2 bits. For example, 00 indicates that the identification type of the device identification of the AIoT device is the identification assigned to the AIoT device by the mobile communication network serving the AIoT device, 01 indicates that the identification type of the device identification of the AIoT device is the identification assigned to the AIoT device by the manufacturer of the AIoT device, 10 indicates that the identification type of the device identification of the AIoT device is the identification assigned to the AIoT device by the application party of the AIoT device, and 11 indicates that the identification type of the device identification of the AIoT device is other identification types other than the above types. The second information can include the content of the device identification of the AIoT device. Depending on the type of identification, the content included in the second information is also different, that is, the length of the second information is correspondingly different.

[0052] For example, if the identification type of the device identification of the AIoT device is an identification assigned to the AIoT device by the mobile communication network serving the AIoT device, then the second information is (or includes) the identification assigned to the AIoT device by the mobile communication network.

[0053] If the identification type of the device identification of the AIoT device is an identification assigned by the manufacturer of the AIoT device to the AIoT device, the second information may include the manufacturer information of the AIoT device manufacturer and the identification assigned by the manufacturer of the AIoT device to the AIoT device. In the frame structure, the identification assigned by the manufacturer of the IoT device to the AIoT device may be after the manufacturer information of the AIoT device manufacturer. For example, the manufacturer information of the AIoT device manufacturer is 3 bytes, and the identification assigned by the manufacturer of the AIoT device to the AIoT device may be 2-8 bytes (because the identification lengths assigned by different manufacturers are different).

[0054] If the identification type of the device identification of the AIoT device is an identification assigned by the application party of the AIoT device to the AIoT device, the second information may include the application party information of the application party of the AIoT device and the identification assigned by the application party of the AIoT device to the AIoT device. In the frame structure, the identification assigned by the application party of the AIoT device to the AIoT device may be after the application party information of the application party of the AIoT device. For example, if the application party information of the application party of the AIoT device is 3 bytes, the identification assigned by the application party of the AIoT device to the AIoT device may be 1-4 bytes (because the identification lengths assigned by different application parties are different).

[0055] The terminal device accesses the operator network where the AIoTMF device is located. The terminal device identifier can be an identifier assigned to the terminal device by the mobile communication network (or operator network) when the terminal device accesses the network, such as SUPI / SUCI / GUTI, etc.

[0056] The identification information can be obtained by constructing the terminal device based on the device identification of the AIoT device and the identification of the terminal device.

[0057] Specifically, the terminal device can be configured as follows: when the terminal device carries an AIoT device, the terminal device can act as a virtual reader to inventory the AIoT device, that is, broadcast a paging message, and the mask in the paging message is empty, which means that any device that receives the paging message initiates access to the terminal device and reports its own device identification, so that the terminal device can obtain the device identification of the AIoT device. The terminal device can generate identification information based on the device identification of the AIoT device and the identification of the terminal device.

[0058] For example, since the length of the terminal device's identifier is fixed, while the device identifier of the AIoT device is not fixed, the terminal device determines the length relationship between the terminal device's identifier and the device identifier of the AIoT device.

[0059] The identification information can be obtained by embedding the terminal device's identification in the device identification of the AIoT device. Assume that the length of the terminal device's identification is X bits, X is an integer greater than 1, and the length of the AIoT device's device identification is K bits, K is an integer greater than 1. If X<K, the terminal device can embed the terminal device's identification into the device identification of the AIoT device to obtain identification information. In one example, the terminal device determines to embed the terminal device's identification between the Z1+nth and Z1+n+1th bits of the device identification of the AIoT device based on KmodX=Z1 to obtain identification information, where n is a preset random positive integer for scrambling, and n is a parameter that the terminal device and the network device have configured in advance.

[0060] Alternatively, the identification information can also be obtained by embedding the device identification of the AIoT device in the identification of the terminal device. Assume that the length of the terminal device identification is X bits, and the length of the device identification of the AIoT device is K bits. If X>K, the terminal device can embed the device identification of the AIoT device into the identification of the terminal device to obtain identification information. In one example, the terminal device determines to embed the device identification of the AIoT device between the Z2+nth and Z2+n+1th bits of the identification of the terminal device based on XmodK=Z2 to obtain identification information, where n is a preset random positive integer for scrambling, and n is a parameter that the terminal device and the network device have configured in advance.

[0061] The terminal device can send the identification information to the AIoT device and instruct the AIoT device to use the identification information to replace the device identification of the AIoT device.

[0062] Correspondingly, AIoTMF can reverse the above process to obtain the terminal device identification and the device identification of the AIoT device respectively.

[0063] For example, the identification information is obtained by embedding the identification of the terminal device in the device identification of the AIoT device. AIoTMF determines the first designated bit to the second designated bit after the first designated bit in the identification information as the identification of the terminal device. After extracting the identification of the terminal device from the identification information, the remaining information is the device identification of the AIoT device.

[0064] Specifically, the length of the terminal device's identifier is X bits, the value of X is predefined or preconfigured by the protocol, the length of the device information is Y bits, and Y is an integer greater than 1. When the length of the terminal device's identifier is known (i.e., predefined or preconfigured by the protocol), AIoTMF can determine that the identifier information is obtained by embedding the terminal device's identifier in the device identifier of the AIoT device based on Y / X>2 (i.e., the device identifier of the AIoT device is longer than the identifier of the terminal device). Furthermore, AIoTMF determines that the Z1+nth bit in the device information is the first designated bit, and determines that the Z1+n+YX-1th bit in the device information is the second designated bit based on (YX)modX=Z1, where n is a preset random positive integer for scrambling; AIoTMF extracts the first designated bit to the second designated bit from the device information to obtain the identifier of the terminal device.

[0065] Alternatively, the identification information is obtained by embedding the device identification of the AIoT device in the identification of the terminal device. The AIoTMF can determine the third designated bit to the fourth designated bit after the third designated bit in the identification information as the device identification of the AIoT device. The remaining information after extracting the device identification of the AIoT device from the identification information is the identification of the terminal device.

[0066] Specifically, the length of the terminal device's identifier is X bits, the value of X is predefined or preconfigured by the protocol, the length of the device information is Y bits, and Y is an integer greater than 1. AIoTMF can determine that the identification information is the device identifier of the AIoT device embedded in the identifier of the terminal device based on Y / X<2; AIoTMF determines that the Z2+nth bit in the device information is the third designated bit position, and determines that the Z2+n+YX-1th bit in the device information is the fourth designated bit position based on Xmod(YX)=Z2, where n is a preset random positive integer for scrambling; AIoTMF extracts the third designated bit position to the fourth designated bit position from the device information to obtain the device identifier of the AIoT device.

[0067] Step S2, AIoTMF determines the storage area of ​​the AIoT device according to the device identification of the AIoT device.

[0068] Case 1: AIoTMF can determine the storage area corresponding to the identification type according to the identification type in the device identification of the AIoT device. The storage area corresponding to the identification type in the device identification of the AIoT device is the storage area of ​​the AIoT device. Different identification types correspond to different storage areas. The identification type in the device identification of the AIoT device indicates that the device identification of the AIoT device is any one of the following: an identification assigned to the AIoT device by the mobile communication network serving the AIoT device, an identification assigned to the AIoT device by the manufacturer of the AIoT device, or an identification assigned to the AIoT device by the application party of the AIoT device.

[0069] Case 2: AIoTMF can determine the target length interval where the length of the device identification of the AIoT device is located from multiple length intervals with different lengths; AIoTMF determines the storage area corresponding to the target length interval, and the storage areas corresponding to the multiple length intervals are different. The storage area corresponding to the target length interval is the storage area of ​​the AIoT device.

[0070] Case 3: AIoTMF can determine the storage area corresponding to the manufacturer indicated by the manufacturer information based on the manufacturer information in the device identification of the AIoT device. Different manufacturers have different corresponding storage areas. The manufacturer indicated by the manufacturer information is the manufacturer of the AIoT device, and the storage area corresponding to the manufacturer indicated by the manufacturer information is the storage area of ​​the AIoT device; or; AIoTMF can determine the storage area corresponding to the application party indicated by the application party information based on the application party information in the device identification of the AIoT device. Different application parties have different corresponding storage areas. The application party indicated by the application party information is a third-party entity that applies the AIoT device, and the storage area corresponding to the application party indicated by the application party information is the storage area of ​​the AIoT device.

[0071] It can be understood that the storage areas of different types of AIoT devices can be the same, so M types of AIoT devices can correspond to N storage areas.

[0072] S202, AIoTMF determines the storage paths of M types of AIoT devices according to the respective locations of N storage areas.

[0073] Among them, AIoTMF can determine the physical optimal path from the terminal device to the N storage areas and the service optimal path located in the service area of ​​the reader according to the respective locations of the N storage areas and the location of the terminal device. AIoTMF determines the physical optimal path or the service optimal path as the storage path of the M AIoT devices.

[0074] The physical optimal path of N storage areas refers to the shortest path that reaches the N storage areas in sequence without considering whether it passes through the service area of ​​the reader. The service optimal path of N storage areas located in the service area of ​​the reader refers to the shortest path that reaches the N storage areas in sequence while passing through the service area of ​​the reader as much as possible.

[0075] On the one hand, AIoTMF can determine the first shortest path from the terminal device to the N storage areas based on the respective locations of the N storage areas and the location of the terminal device. The first shortest path is the physically optimal path. For example, AIoTMF determines all paths from the terminal device to the N storage areas based on the respective locations of the N storage areas and the location of the terminal device. AIoTMF can select the shortest first shortest path from all paths from the terminal device to the N storage areas. Among them, AIoTMF can plan all paths from the terminal device to the N storage areas in the road network based on the road network.

[0076] On the other hand, AIoTMF determines the second shortest path from the terminal device to the N storage areas and located in the service area of ​​the reader based on the respective locations of the N storage areas, the location of the terminal device, and the service area of ​​the reader. The second shortest path is the optimal service path.

[0077] Specifically, AIoTMF determines the optimal service sub-paths between the terminal device and the N storage areas, and determines the optimal service sub-path between any two storage areas in the N storage areas, according to the respective positions of the N storage areas, the position of the terminal device, and the service area of ​​the reader. Among them, the optimal service sub-path passes through the service area of ​​at least one reader. If the reader is a base station, the service area of ​​the reader is the service cell. For example, for the i-th storage area in the N storage areas, i is an integer traversing from 1 to N; AIoTMF can determine all paths between the terminal device and the i-th storage area that pass through the service area of ​​the reader according to the respective positions of the i-th storage areas, the position of the terminal device, and the service area of ​​the reader, and determine the shortest path in the path as the optimal service sub-path between the terminal device and the i-th storage area. AIoTMF can determine all paths between the optimal service sub-paths between any two storage areas that pass through the service area of ​​the reader according to the respective positions of the i-th storage areas and the service area of ​​the reader, and determine the shortest path in the path as the optimal service sub-path between any two storage areas. AIoTMF combines the service optimal sub-paths between the terminal device and the N storage areas respectively with the service optimal sub-path between any two storage areas, and determines the shortest path from the terminal device to the N storage areas in the combination as the second shortest path.

[0078] Finally, AIoTMF can determine the path coupling ratio between the physical optimal path or the service optimal path; if the path coupling ratio is greater than the preset ratio threshold, the service optimal path is determined as the storage path of M types of AIoT devices, otherwise, the physical optimal path is determined as the storage path of M types of AIoT devices. In other words, considering the location tracking of the storage of IoT devices through the service area of ​​the reader, the service optimal path is usually greater than the physical optimal path. In this case, a judgment can be made by setting a ratio threshold to achieve a balance between mobility tracking and distance, that is, taking into account mobility tracking and storage efficiency. Among them, the preset ratio threshold can be set according to the actual situation, such as 60%, 65% or other ratios, without specific restrictions.

[0079] S203, AIoTMF sends the storage paths of M types of AIoT devices to the terminal device.

[0080] AIoTMF sends a NAS message to the terminal device. The NAS message contains the storage path of M types of AIoT devices, which is used for the terminal device to move along the storage path. Correspondingly, if the storage path of M types of AIoT devices passes through the service area of ​​the reader, AIoTMF can also track the mobility of M types of AIoT devices, such as instructing the reader to take inventory of M types of AIoT devices. When the terminal device moves to the service area of ​​the reader, the reader can obtain the identification of the corresponding AIoT device through the inventory and report it to AIoTMF. In this way, AIoTMF knows that the AIoT device has moved to the vicinity of the location of the reader, thus realizing mobility tracking.

[0081] In summary, by enhancing AIoTMF, AIoTMF can plan the best storage paths to the N storage areas for the M types of AIoT devices in their respective storage areas, such as N storage areas, and send the storage paths to the terminal devices carrying the M types of AIoT devices, so as to achieve efficient and reliable storage path planning for A-IoT devices.
