Description
Technical Field
The application relates to the field of communication, in particular to an identification method and device for nodes of the Internet of things.
Background
Narrow-band internet of things (NB-IOT) and ZigBee protocol (ZigBee) are the main Internet of things protocols at present. Telecom operators mainly deploy NB-IOT as wide area coverage, and deploy ZigBee to realize local area coverage. In practical use, operators often adopt the two protocols for mixed networking. In the hybrid networking, an NB-IOT node is used as a main node to communicate with the Internet, and a ZigBee node is used as an actual control node to communicate with Internet of things equipment.
The global unified 64-bit MAC address of the ZigBee node is usually written into the node when the ZigBee node leaves a factory, and usually, the MAC address does not participate in routing and addressing, so that the MAC address cannot be used as the identifier of the node. Therefore, the Internet of things equipment cannot conveniently address the ZigBee node.
At present, a common method is to additionally establish an article identification system in a hybrid networking, and establish an independent coding system for the article identification system for addressing of the internet of things devices. However, such a method requires a large amount of engineering for the equipment already in use on the web. Meanwhile, the independent coding system does not participate in the system routing function, and further network overhead is increased. Therefore, an appropriate solution is urgently needed for the technical problem of how to identify the ZigBee node in the NB-IOT and ZigBee mixed networking.

In order to facilitate understanding of the technical solutions of the present application, some technical terms are described below.
1. Narrow-band Internet of things
Narrow-band internet of things (NB-IOT) is an important branch of the internet of everything. The NB-IOT is constructed in a cellular network, only consumes about 180kHz bandwidth, and can be directly deployed in a GSM network, a UMTS network or an LTE network so as to reduce the deployment cost and realize smooth upgrading.
In the IOT domain, NB-IOT is an emerging technology that supports cellular data connectivity for low power devices over a wide area network, and is therefore also referred to as a low power wide area network. The NB-IOT supports efficient connection of devices with long standby time and high requirements for network connection. Due to the advantage of low power consumption of the NB-IOT, the standby time of the NB-IOT terminal module can be as long as 10 years, while still providing very comprehensive indoor cellular data connection coverage.
The NB-IOT has the advantages of low power consumption, wide coverage, low cost, large capacity and the like, so that the NB-IOT can be widely applied to various vertical industries, such as remote meter reading, asset tracking, intelligent parking, intelligent agriculture and the like.
2. Protocol for zigbee
The ZigBee protocol (ZigBee) is a wireless network protocol for low-speed short-distance transmission, and the bottom layer adopts a medium access layer and a physical layer specified by IEEE802.15.4 standard.
ZigBee is a novel wireless communication technology, and is suitable for a series of electronic component devices with short transmission range and low data transmission rate. The ZigBee wireless communication technology can achieve coordinated communication among thousands of tiny sensors by means of special radio standards, and thus the technology is often called Home RF Lite wireless technology and FireFly wireless technology.
The ZigBee wireless communication technology can also be applied to the fields of control, automation and the like based on wireless communication in a small range, can save wired cables among computer equipment and a series of digital equipment, and can further realize wireless networking among various different digital equipment to realize mutual communication or access the Internet.
3. Binary coded decimal number
Binary-Coded Decimal (BCD), also called BCD code, is a coding scheme that uses 4-digit Binary numbers to represent 10 digits, 0-9, in 1-digit Decimal numbers.
As a binary digital coding form, the BCD code uses four bits to store a decimal number, so that the conversion between binary and decimal is rapidly carried out. This coding technique is often used in applications requiring accurate calculations for very long strings of numbers.
Compared with the common floating-point notation, the BCD code is adopted, so that the accuracy of the numerical value can be saved, and the time consumed by the computer in the floating-point operation can be saved. Moreover, for other calculations that require high precision, BCD encoding is also commonly used.
BCD codes are generally classified into 6 categories of 8421, 5421, 2421, the remaining 3 codes, the remaining 3 cyclic codes, and the Gray code. Among them, 8421BCD code is the most basic and most commonly used BCD code.
4. International mobile equipment identity code
The International Mobile Equipment Identity (IMEI), which is a mark for distinguishing mobile equipment, is stored in the mobile equipment and can be used for monitoring stolen or invalid mobile equipment. The IMEI is an "electronic serial number" consisting of 15 digits, which corresponds one-to-one to each mobile device and is unique throughout the world. Each mobile device, after assembly, will be assigned a globally unique IMEI that will be recorded from manufacture to delivery by the manufacturer.
In order to solve the technical problem how to identify a ZigBee node when NB-IOT and ZigBee are in hybrid networking, the embodiment of the application provides an identification method and device of an Internet of things node.
As shown in fig. 1, the architecture of an NB-IOT and ZigBee mixed identity system to which the technical solution provided by the embodiment of the present application is applied is shown. The hybrid identification system may include: the system comprises an identification analysis server, an NB-IOT node and a ZigBee node. The identifier analysis server corresponds to the NB-IOT nodes one to one, and one NB-IOT node can be connected with a plurality of ZigBee nodes.
The identification analysis server stores the identifications of all ZigBee nodes, and the identifications can be used as unified identifications of the ZigBee nodes and also can be used as routing addresses of the ZigBee nodes in an IPv6 network. The identification analysis server has identification conversion capability, and can map the identification information of the ZigBee node with the information of the actual function, the manufacturer and the like of the ZigBee node, or convert the identification of the ZigBee node into the identification format of other identification systems.
And the NB-IOT node is used as a master node to communicate with the Internet. The NB-IOT and ZigBee dual-protocol stacks are built in, namely, communication can be finished with the NB-IOT node and the ZigBee node respectively, and the distributed IPv6 address of the ZigBee node and ZigBee node equipment information are reported to the identification analysis server, so that identification coding of the ZigBee node is finished finally.
And the ZigBee node is used as an actual control node to communicate with the Internet of things equipment. The ZigBee node is connected with the final Internet of things equipment and reports the 64-bit MAC address of the ZigBee node to the NB-IOT node. Meanwhile, the ZigBee node needs to report function information such as a device type, a manufacturer, a measurement range, and a measurement unit connected to the ZigBee node.
In addition, the network architecture and the service scenario described in the embodiment of the present application are for more clearly illustrating the technical solution of the embodiment of the present application, and do not constitute a limitation to the technical solution provided in the embodiment of the present application, and it can be known by a person skilled in the art that the technical solution provided in the embodiment of the present application is also applicable to similar technical problems along with the evolution of the network architecture and the appearance of a new service scenario.
The technical solution provided by the present application is specifically explained below with reference to the drawings of the specification.
As shown in fig. 2, a method for identifying a node of an internet of things provided in the embodiment of the present application includes the following steps:
and S101, the NB-IOT node receives the MAC address sent by the ZigBee node.
Wherein, the MAC address of the ZigBee node consists of 64 bits. The MAC address is written into the ZigBee node when the ZigBee node leaves a factory.
It should be noted that, since the 64-bit MAC address does not participate in routing and addressing, it cannot be directly used as an identifier of the ZigBee node.
Optionally, the ZigBee node further reports the function information to the NB-IOT node. The functional information may include one or more of the following parameters: the type, the manufacturer, the measurement range, the measurement unit and the like of the equipment connected with the ZigBee node.
And S102, the NB-IOT node generates a routing address of the NB-IOT node according to the IMEI of the NB-IOT node.
The IMEI is an identifier written in the NB-IOT node when leaving the factory, the total length is 15 bits, and each digit only uses digits from 0 to 9.
Optionally, the NB-IOT node supplements one bit of 0 after the original 15-bit IMEI address of the NB-IOT node, and acquires the sequence number. The NB-IOT node then converts the sequence number into a 64-bit routing address via BCD encoding.
It is understood that the sequence number consists of an IMEI and a bit of 0.
Illustratively, the original 15-bit IMEI address of the NB-IOT node is "012345678912345" when the 8421BCD coding category is employed. One bit 0 is added after the IMEI address, resulting in a sequence number of "0123456789123450". Then the serial number is converted by BCD coding, and the 64-bit routing address is obtained as '0000000100100011010001010110011110001001000100100011010001010000'.
S103, the NB-IOT node generates an IPV6 address of the ZigBee node according to the MAC address of the ZigBee node and the routing address of the NB-IOT node.
Wherein, the IPV6 address of the ZigBee node consists of 128 bits.
Optionally, in the IPv6 address, the NB-IOT node uses the first bit to the 64 th bit to carry a routing address of the NB-IOT node, and uses the 65 th bit to the 128 th bit to carry a MAC address of the ZigBee node.
As shown in table 1 below, a 128-bit IPv6 address structure of an identifier of a ZigBee node designed for the embodiment of the present application.
Table 1 IPv6128 bit address structure of ZigBee node
| First 64 bits | Last 64 bits |
| Routing address of NB-IOT node | 64-bit MAC address of ZigBee node |
Optionally, in the IPv6 address, the NB-IOT node uses the first bit to the 64 th bit to carry the MAC address of the ZigBee node, and uses the 65 th bit to the 128 th bit to carry the routing address of the NB-IOT node.
As shown in table 2 below, a 128-bit IPv6 address structure of an identifier of a ZigBee node designed for the embodiment of the present application.
Table 2 IPv6128 bit address structure of ZigBee node
| First 64 bits | Last 64 bits |
| 64-bit MAC address of ZigBee node | Routing address of NB-IOT node |
Based on the technical scheme shown in fig. 2, the NB-IOT node identifies the ZigBee node in the hybrid networking and generates a 128-bit IPv6 address of the ZigBee node, so that the internet of things device can conveniently address and access the ZigBee node without upgrading the device in the original hybrid networking and without additionally establishing an article identification system and an independent coding system, thereby effectively reducing the cost consumption and network overhead of the hybrid networking system.
As shown in fig. 3, for the identification method of an internet of things node provided in the embodiment of the present application, after step S103, the method further includes the following steps:
and S201, the NB-IOT node sends the IPV6 address of the ZigBee node to the identification resolution server.
Optionally, the NB-IOT node further sends the function information of the ZigBee node to the identity resolution server.
S202, the identification resolution server stores the IPV6 address of the ZigBee node.
It can be understood that the identification resolution server can determine a unique ZigBee node through the IPv6 address of the ZigBee node.
Optionally, if the identifier resolution server further receives the function information of the ZigBee node, the identifier resolution server may establish a correspondence between the IPv6 address of the ZigBee node and the function information.
For example, the IPv6 address and function information may be as shown in table 3.
TABLE 3
| IPv6 address | Function information |
Therefore, the equipment of the Internet of things can address the ZigBee node to be accessed by the equipment of the Internet of things through the access identifier resolution server. Meanwhile, the identification analysis server can convert the IPv6 address of the ZigBee node into the identification of other identification systems, so that different types of Internet of things equipment can access the ZigBee node.
As shown in fig. 4, the method for identifying a node of an internet of things provided in the embodiment of the present application further includes, before step 101, the following steps:
s301, the NB-IOT node receives an access request message sent by the ZigBee node.
The access request message is used for the ZigBee node to request to access the Internet of things.
And S302, the NB-IOT node sends a response message to the ZigBee node.
The response message is used for indicating that the ZigBee node is allowed to access the Internet of things.
Therefore, after the ZigBee node is accessed to the Internet of things system and powered on, the ZigBee node can actively send a network access request to the NB-IOT node to apply for joining the Internet of things. Then, the NB-IOT node identifies the ZigBee node and generates a 128-bit IPv6 address of the ZigBee node, so that the Internet of things equipment can access the corresponding ZigBee node through the IPv6 address.
