Description

Technical Field

[0001] The present invention relates to the field of wireless communications, and in particular to a star flash short-range communication technology in the field of wireless communications, and more particularly to a management method for the coexistence of star flash multiple domains. Background Art

[0002] With the rapid development of science and technology, industries such as smart cars, smart homes and smart manufacturing are undergoing unprecedented changes, and these fields have put forward higher and more diversified requirements for wireless communication technology. Although traditional wireless short-range communication technologies, such as Bluetooth and WiFi, have played an important role in past communication scenarios, their limitations in terms of latency, reliability, synchronization accuracy and security have become increasingly prominent in the face of emerging application scenarios, and they can no longer meet the needs of current and future technological evolution.

[0003] To meet these challenges, researchers have proposed a new generation of wireless short-range communication technology, Star Flash Short-Range Technology. This technology aims to overcome the bottlenecks of existing technologies through innovative design and optimization, and meet the wireless communication needs in complex scenarios such as smart car autonomous driving, smart home device interconnection, and smart manufacturing production line collaboration.

[0004] However, with the widespread application of Starflash short-range communication technology and the surge in the number of communication nodes, how to efficiently build and manage a network where multiple Starflash communication domains coexist to ensure that the wireless transmission needs of a large number of Starflash communication nodes are met has become an urgent problem to be solved. The existing Starflash short-range standard T / XS 20004-2022 "Starflash Wireless Communication System Basic Service Layer Multi-Domain Coordination and Management V1.0.0" provides coordination and management methods in multi-domain management mode and non-management mode. In this document, the following are given: Figure 1 The example of multi-domain coordination management topology including three Star Flash communication domains is shown. Figure 1 It includes G1 star flash communication domain, G2 star flash communication domain and G3 star flash communication domain, among which, G1 star flash communication domain includes management node G1, management node G2, management node G3 and terminal node T1, and management node G1, as a multi-domain management node, is uniformly responsible for the spectrum resource configuration of G2 star flash communication domain, G3 star flash communication domain and terminal node T1; G2 star flash communication domain includes management node G2, terminal node T3 and terminal node T4, and management node G2 allocates spectrum to terminal node T3 and terminal node T4 based on the spectrum resources allocated by the multi-domain management node G1; G3 star flash communication domain includes management node G3 and terminal node T2, and management node G3 allocates spectrum to terminal node T2 based on the spectrum resources allocated by the multi-domain management node G1.

[0005] Although the existing multi-domain management methods can achieve multi-domain coordinated management, the communication distance of Star Flash technology is relatively limited, usually only between ten meters and tens of meters. When the number of nodes increases and the distribution range is wider, the multi-domain management node may not be able to directly cover all the management nodes in the Star Flash communication domain, resulting in blind spots in management. In addition, if the management nodes that are not within the communication range of the multi-domain management node randomly select the working frequency band for communication, it may not only cause frequency band conflicts, but also cause interference to nodes in other Star Flash communication domains, thereby reducing the communication performance and stability of the multi-domain coordination group composed of multiple Star Flash communication domains. Summary of the invention

[0006] Therefore, the purpose of the present invention is to overcome the defects of the above-mentioned prior art and provide a management method for the coexistence of multiple star flash domains.

[0007] The objectives of the present invention are achieved through the following technical solutions.

[0008] According to a first aspect of the present invention, there is provided a management method for Star Flash multi-domain coexistence, which is used for centrally managing available spectrum resources in multiple Star Flash communication domains, each of which includes a management node and multiple terminal nodes paired and authenticated with the management node, and the method includes: setting any one of the multiple management nodes as a master management node, and setting the remaining management nodes as slave management nodes, and each slave management node needs to be paired and authenticated with the master management node; wherein the master management node is used to allocate available spectrum resources to the slave management nodes that are paired and authenticated with it, and each slave management node is used to allocate spectrum resources to the terminal nodes that are paired and authenticated with the slave management node based on the available spectrum resources allocated to it by the master management node; the master management node is configured to: periodically broadcast the discovered information so that the slave management nodes can be authenticated through the discovered information The slave management node is configured as follows: the slave management node within the communication range of the master management node initiates a first type of access request to the master management node through the discovered information to achieve pairing authentication with the master management node; the slave management node that is not within the communication range of the master management node initiates a first type of access request to the master management node through the discovered information, and sends the first type of access request to other slave management nodes that have been paired with the master management node for authentication, so that other slave management nodes that have been paired with the master management node forward the first type of access request to the master management node, thereby achieving pairing authentication between the slave management node that is not within the communication range of the master management node and the master management node; the slave management node is also configured as follows: periodically broadcast the discovered information so that the terminal node initiates a second type of access request through the discovered information to achieve pairing authentication with the slave management node.

[0009] In some embodiments of the present invention, the method includes: the slave management node within the communication range of the master management node is configured to perform pairing authentication with the master management node in the following manner: the slave management node scans the discovered information broadcast by the master management node, and sends a first type of access request to the master management node according to preset rules to achieve pairing authentication with the master management node.

[0010] In some embodiments of the present invention, the method includes: a slave management node that is not within the communication range of the master management node is configured to perform pairing authentication with the master management node in the following manner: the slave management node that is not within the communication range of the master management node scans the discovered information broadcast by the master management node, and sends a first type of access request to the slave management node with the strongest surrounding receiving power and that has been paired and authenticated with the master management node according to preset rules, so that the slave management node with the strongest surrounding receiving power and that has been paired and authenticated with the master management node forwards the received first type of access request to the master management node according to the preset rules, thereby realizing pairing authentication between the slave management node that is not within the communication range of the master management node and the master management node.

[0011] In some embodiments of the present invention, the preset rule is: each slave management node is configured with only one set of transceiver links, and the set of transceiver links supports each slave management node to communicate with other slave management nodes as a management node or a terminal node, and each slave management node to communicate with the main management node as a terminal node; when a slave management node within the communication range of the main management node performs pairing authentication with the main management node, the slave management node sends a first-class access request to the main management node through its own configured transceiver link as a terminal node; when a slave management node that is not within the communication range of the main management node performs pairing authentication with the main management node, the slave management node sends a first-class access request to the slave management node with the strongest receiving power in the surrounding area and has been paired with the main management node through its own configured transceiver link as a terminal node, and the slave management node with the strongest receiving power in the surrounding area and has been paired with the main management node receives the first-class access request of the slave management node that is not within the communication range of the main management node through its own configured transceiver link as a management node, and then forwards the first-class access request of the slave management node that is not within the communication range of the main management node to the main management node through its own configured transceiver link as a terminal node.

[0012] In some embodiments of the present invention, the preset rules are: each slave management node is configured with two sets of transceiver links, wherein one set is a management transceiver link, used to enable the slave management node to send and receive data as a management node; the other set is a terminal transceiver link, used to enable the slave management node to send and receive data as a terminal node; when a slave management node within the communication range of the master management node performs pairing authentication with the master management node, the slave management node sends a first-class access request to the master management node through the terminal transceiver link; when a slave management node that is not within the communication range of the master management node performs pairing authentication with the master management node, the slave management node sends a first-class access request to the slave management node with the strongest receiving power in the surrounding area and has been paired and authenticated with the master management node through the terminal transceiver link, and the slave management node with the strongest receiving power in the surrounding area and has been paired and authenticated with the master management node receives the first-class access request of the slave management node that is not within the communication range of the master management node through the management transceiver link, and then forwards the first-class access request of the slave management node that is not within the communication range of the master management node to the master management node through the terminal transceiver link.

[0013] In some embodiments of the present invention, the method includes the main management node being configured to allocate available spectrum resources to the slave management node in the following manner: when the ratio of the number of slave management nodes managed by the main management node to the number of frequency points is greater than or equal to a preset threshold, the available spectrum resources are allocated in a semi-static spectrum configuration management manner; otherwise, the available spectrum resources are allocated in a static spectrum configuration management manner.

[0014] In some embodiments of the present invention, the semi-static spectrum configuration management method is: based on a preset semi-static period, the master management node reallocates available spectrum resources to each slave management node within each semi-static period; the static spectrum configuration management method is: based on a preset static period, the management node reallocates available spectrum resources to each slave management node within each static period; wherein the preset semi-static period value is less than and not equal to the preset static period value.

[0015] In some embodiments of the present invention, the method also includes the terminal node being configured to perform pairing authentication with the slave management node in the following manner: after the terminal node scans the discovered information broadcast by the slave management node, it selects the slave management node with the strongest signal based on the signal strength of the scanned discovered information, and initiates a second type of access request to the slave management node for pairing authentication.

[0016] Compared with the prior art, the advantages of the present invention are: (1) through the single-hop or multiple communication links between management nodes, to assist in the coordinated management of multiple Star Flash communication domains, while avoiding the interference problem caused by the management nodes that are not within the communication range of the main management node randomly selecting the working frequency band for communication; (2) introducing static spectrum configuration management methods and semi-static spectrum configuration management methods, thereby reducing the spectrum usage conflicts of adjacent Star Flash communication domains.

[0021] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below through specific embodiments in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0022] As mentioned in the background technology section, although the existing multi-domain management methods can achieve multi-domain coordinated management, the communication distance of Star Flash technology is relatively limited, usually only between ten meters and tens of meters. When the number of nodes increases and the distribution range is wider, the multi-domain management node may not be able to directly cover all the management nodes in the Star Flash communication domain, resulting in blind spots in management. In addition, if the management nodes that are not within the communication range of the multi-domain management node randomly select the working frequency band for communication, it may not only cause frequency band conflicts, but also cause interference to nodes in other Star Flash communication domains, thereby reducing the communication performance and stability of the multi-domain coordination group composed of multiple Star Flash communication domains.

[0023] In order to solve the above problems, the inventors proposed that a single-hop or multiple communication links between management nodes can be used to assist in the coordinated management of multiple Star Flash communication domains, while avoiding the interference problem caused by the random selection of working frequency bands by management nodes that are not within the communication range of the multi-domain management nodes.

[0024] In summary, if Figure 2As shown, the present invention proposes a management method for the coexistence of multiple Star Flash domains, which is used for centrally managing the available spectrum resources in multiple Star Flash communication domains, each of which includes a management node and multiple terminal nodes paired and authenticated with the management node. The method includes: setting any one of the multiple management nodes as a master management node, and setting the remaining management nodes as slave management nodes, and each slave management node needs to be paired and authenticated with the master management node; wherein the master management node is used to allocate available spectrum resources to the slave management nodes that are paired and authenticated with it, and each slave management node is used to allocate spectrum resources to the terminal nodes that are paired and authenticated with the slave management node based on the available spectrum resources allocated by the master management node; the master management node is configured to: periodically broadcast the discovered information so that the slave management nodes can communicate with the master management node through the discovered information The management node performs pairing authentication; the slave management node is configured as follows: the slave management node within the communication range of the main management node initiates a first type of access request to the main management node through the discovered information to achieve pairing authentication with the main management node; the slave management node not within the communication range of the main management node initiates a first type of access request to the main management node through the discovered information, and sends the first type of access request to other slave management nodes that have been paired with the main management node for authentication, so that other slave management nodes that have been paired with the main management node forward the first type of access request to the main management node, thereby achieving pairing authentication between the slave management node that is not within the communication range of the main management node and the main management node; the slave management node is also configured as follows: periodically broadcast the discovered information so that the terminal node initiates a second type of access request through the discovered information to perform pairing authentication with the slave management node.

[0025] In order to better understand the present invention, the master-slave pairing authentication, slave pairing authentication and spectrum allocation management are respectively described in detail below in conjunction with specific embodiments.

[0026] 1. Master-slave pairing authentication

[0027] The master-slave pairing authentication refers to the process of pairing authentication between the master management node and other slave management nodes, specifically including the pairing authentication between the master management node and the slave management nodes within its communication range, and the pairing authentication between the master management node and the slave management nodes outside its communication range.

[0028] According to one embodiment of the present invention, the slave management node within the communication range of the master management node is configured to perform pairing authentication with the master management node in the following manner: the slave management node scans the discovered information broadcast by the master management node, and sends a first type of access request to the master management node according to preset rules to achieve pairing authentication with the master management node.

[0029] According to one embodiment of the present invention, a slave management node that is not within the communication range of the master management node is configured to perform pairing authentication with the master management node in the following manner: the slave management node that is not within the communication range of the master management node scans the discovery information broadcast by the master management node, and sends a first type of access request to the slave management node with the strongest surrounding receiving power that has been paired and authenticated with the master management node according to preset rules, so that the slave management node with the strongest surrounding receiving power that has been paired and authenticated with the master management node forwards the received first type of access request to the master management node according to the preset rules, thereby realizing pairing authentication between the slave management node that is not within the communication range of the master management node and the master management node.

[0030] According to one embodiment of the present invention, the preset rule is: each slave management node is configured with only one set of transceiver links, and the set of transceiver links supports each slave management node to communicate with other slave management nodes as a management node or a terminal node, and each slave management node to communicate with the main management node as a terminal node; when a slave management node within the communication range of the main management node performs pairing authentication with the main management node, the slave management node sends a first-class access request to the main management node through its own configured transceiver link as a terminal node; when a slave management node that is not within the communication range of the main management node performs pairing authentication with the main management node, the slave management node sends a first-class access request to the slave management node with the strongest receiving power in the surrounding area and has been paired with the main management node through its own configured transceiver link as a terminal node, and the slave management node with the strongest receiving power in the surrounding area and has been paired with the main management node receives the first-class access request of the slave management node that is not within the communication range of the main management node through its own configured transceiver link as a management node, and then forwards the first-class access request of the slave management node that is not within the communication range of the main management node to the main management node through its own configured transceiver link as a terminal node. It should be noted that when only one set of transceiver links is configured in the slave management node, it is necessary to switch the management node identity and the terminal node identity as needed. Therefore, the frame structure of the slave management node can be adjusted and designed, and a flexible frame structure design can be introduced to assist communication. The frame structure can be designed as a GG, GT or TG working mode, wherein the GG working mode indicates that both communicating parties communicate as management nodes, and the GT or TG working modes indicate that one party is a management node and the other is a terminal node. The difference is that the GT working mode indicates that the data sender sends data as a management node, and the data receiver receives data as a terminal node; the TG working mode indicates that the data sender sends data as a terminal node, and the data receiver receives data as a management node.

[0031] According to one embodiment of the present invention, the preset rules are: each slave management node is configured with two sets of transceiver links, wherein one set is a management transceiver link, which is used to enable the slave management node to send and receive data as a management node; the other set is a terminal transceiver link, which is used to enable the slave management node to send and receive data as a terminal node; when the slave management node within the communication range of the main management node performs pairing authentication with the main management node, the slave management node sends a first-class access request to the main management node through the terminal transceiver link; when the slave management node that is not within the communication range of the main management node performs pairing authentication with the main management node, the slave management node sends the first-class access request to the slave management node with the strongest receiving power in the surrounding area and has been paired and authenticated with the main management node through the terminal transceiver link, and the slave management node with the strongest receiving power in the surrounding area and has been paired and authenticated with the main management node receives the first-class access request of the slave management node that is not within the communication range of the main management node through the management transceiver link, and then forwards the first-class access request of the slave management node that is not within the communication range of the main management node to the main management node through the terminal transceiver link. Among them, when there are two sets of transceiver links from the management node, there is no need to switch the management node identity and the terminal node identity. It is only necessary to select different transceiver links for data transmission according to the transmission requirements, and the two sets of transceiver links can transmit data at the same time.

[0032] It should be noted that all slave management nodes that have completed the master-slave pairing authentication form a Star Flash communication domain with the master management node, and within the Star Flash communication domain, the master management node allocates the spectrum resources available in the Star Flash communication domain where the slave management node is located to each slave management node through centralized spectrum resource management. Among them, the spectrum resources managed by the master management node can be authorized frequency bands or unauthorized frequency bands. If the spectrum resources managed by the master management node are authorized frequency bands, the spectrum resources are exclusive; if the spectrum resources managed by the master management node are authorized frequency bands, the spectrum resources are shared with other communication systems.

[0033] 2. Slave Pairing Authentication

[0034] The slave-side pairing authentication refers to the process of pairing authentication between the slave management node and the terminal node.

[0035] According to one embodiment of the present invention, the terminal node is configured to perform pairing authentication with the slave management node in the following manner: after the terminal node scans the discovered information broadcast by the slave management node, it selects the slave management node with the strongest signal according to the signal strength of the scanned discovered information, and initiates a second-type access request to the slave management node for pairing authentication. It should be noted that the terminal node is only configured with one set of transceiver links to support the terminal node to communicate with the slave management node as a terminal node, and when the slave management node is only configured with one set of transceiver links, the terminal node sends the second-type access request to the slave management node as a terminal node through its own configured transceiver link, and the slave management node receives the second-type access request through its own configured transceiver link as a management node; when the slave management node is configured with two sets of transceiver links, the terminal node sends the second-type access request to the slave management node as a terminal node through its own configured transceiver link, and the slave management node receives the second-type access request through the management transceiver link. It should be noted that if the terminal node scans and detects the discovery information broadcast by multiple slave management nodes, it can select the slave management node with the strongest signal strength for pairing authentication, or select other slave management nodes for pairing authentication according to actual needs.

[0036] It should also be noted that the terminal node that completes the slave pairing authentication and the corresponding slave management node form a Star Flash communication domain, and within the Star Flash communication domain, the slave management node allocates spectrum to each terminal node through centralized spectrum resource management.

[0037] 3. Spectrum Allocation Management

[0038] After pairing authentication, the master management node can allocate available spectrum resources to the slave management node that is paired and authenticated with it, and the slave management node can also allocate spectrum to the terminal node that is paired with it according to the allocated available spectrum resources.

[0039] According to an embodiment of the present invention, the master management node is configured to allocate available spectrum resources to the slave management node in the following manner: when the ratio of the number of slave management nodes managed by the master management node to the number of frequency points is greater than or equal to a preset threshold, the available spectrum resources are allocated in a semi-static spectrum configuration management manner; otherwise, the available spectrum resources are allocated in a static spectrum configuration management manner. It should be noted that the preset threshold is determined by actual needs and is not specifically limited in the present invention.

[0040] According to an embodiment of the present invention, the semi-static spectrum configuration management method is: based on a preset semi-static period, the master management node reallocates available spectrum resources to each slave management node in each semi-static period; the static spectrum configuration management method is: based on a preset static period, the management node reallocates available spectrum resources to each slave management node in each static period; wherein the preset semi-static period value is less than and not equal to the preset static period value. It should be noted that in the semi-static spectrum configuration management method, the preset semi-static period can be set as a superframe, and a certain number of slave management nodes are activated in each superframe, and the spectrum is reallocated orthogonally to the activated slave management nodes. It should also be noted that in the semi-static spectrum configuration management method, when the master management node allocates spectrum resources to the slave management node in each semi-static period, it can comprehensively consider the business demand, business active time, and geographical location distribution of the terminal nodes in the communication domain of each slave management node in the star flash communication domain where each slave management node is located, and other information to reallocate spectrum resources to each slave management node.

[0041] The reason for setting up semi-static spectrum configuration management and static spectrum configuration management is that as the number of Star Flash communication domains increases, the number of frequency points managed by the master management node may be difficult to orthogonally reuse in multiple Star Flash communication domains. Therefore, a preset threshold is introduced. When the ratio of the number of slave management nodes managed by the master management node to the number of frequency points is greater than or equal to the preset threshold, the semi-static spectrum configuration management method is used to allocate available spectrum resources; otherwise, the static spectrum configuration management method is used to allocate available spectrum resources, thereby reducing the spectrum usage conflicts of adjacent Star Flash communication domains.

[0042] In order to better understand the present invention, Figure 3 The StarFlash multi-domain management example is shown for illustration.

[0043] Figure 3 There are three management nodes and two terminal nodes, one of which is set as the main management node, referred to as the main G node; the other two management nodes are set as slave management nodes, referred to as slave G1 node and slave G2 node, and the slave G1 node is within the communication range of the main management node, and the slave G2 node is not within the communication range of the main management node; the terminal nodes are T1 node and T2 node. Figure 3 The master-slave pairing authentication process, slave pairing authentication process and spectrum allocation management process shown are used to illustrate. Figure 3 In the example given, each slave management node is configured with only one set of transceiver links, and needs to switch identities according to different data transmission requirements.

[0044] like Figure 3As shown, after the master G node is powered on, it will periodically broadcast the information of being discovered; after the slave G1 node is powered on, it will scan the broadcast information and be configured as a terminal node identity (identity T) to initiate a first-class access request message through its own configured transceiver link; after the master G node receives the first-class access request from the slave G1, it will perform pairing authentication with the slave G1 node. After the pairing is completed, the slave G1 node requests the master G node for the spectrum resource configuration information for the slave G1 star flash communication domain where it is located. After the decision of the centralized spectrum management unit of the master G node, the master G node will issue the spectrum resource configuration information of the slave G1 star flash communication domain. Among them, the spectrum resource allocation within the slave G1 star flash communication domain will be managed by the slave G1 node, and must comply with the usage rules in the spectrum resource configuration information of the slave G1 star flash communication domain issued by the master G node.

[0045] After obtaining the available spectrum resource configuration information from the G1 node, it switches its identity from the terminal node identity to the management node identity (identity G), and begins to periodically broadcast the discovery information; after scanning the discovery information from the G1 node, the T1 node will initiate a second-type access request to the G1 node through its own configured transceiver link as a terminal node; after receiving the second-type access request from the T1 node, the G1 node will perform pairing authentication with the T1 node; after pairing is completed, the T1 node will perform data communication and interaction with the G1 node. Among them, if the T1 node scans the discovery information of multiple G nodes, it will try access requests and pairing authentication in order from strong to weak according to the received signal strength, or manually select the G node to be accessed for pairing authentication.

[0046] When the slave G2 node wants to access the master G node but is not within the communication range of the master G node, it needs to access the master G node in a multi-hop manner with the assistance of other slave G nodes that have already accessed the master G node. Specifically, the pairing authentication process between the slave G2 node and the master G node is as follows: after the slave G2 node is powered on, it scans the broadcast information and is configured as a terminal node identity (identity T) to initiate a first-class access request message, and sends the first-class access request message to the slave G1 node through its own configured transceiver link; the slave G1 node receives the first-class access request from the slave G2 node as a management node through its own configured transceiver link, and then forwards the first-class access request from the slave G2 to the master G1 node as a terminal node through its own configured transceiver link, so as to assist the slave G2 node in pairing authentication with the master G node and send spectrum resource configuration information.

[0047] After obtaining the available spectrum resource configuration information from the G2 node, it switches its identity from the terminal node identity to the management node identity (identity G) and starts to periodically broadcast the discovery information; after scanning the discovery information from the G2 node, the T2 node will initiate a second-type access request to the G2 node; after the G2 node receives the second-type access request from the T2 node, it will perform pairing authentication with the T2 node; after the pairing is completed, the T2 node will perform data communication and interaction with the G2 node.

[0048] Since the master G node may continuously access new slave G nodes, and as the number of slave G nodes increases, the number of frequencies managed by the master management node may be difficult to orthogonally reuse in multiple star flash communication domains. Therefore, it is necessary to determine whether the ratio of the number of slave G nodes managed by the master G node to the number of managed frequencies is greater than or equal to the threshold. If the ratio is greater than or equal to the threshold, a semi-static spectrum configuration management method is used to reallocate available spectrum resources to the slave G1 node and the slave G2 node, and the semi-static spectrum configuration information of the reallocated slave G1 node and the semi-static spectrum configuration information of the slave G2 node are sent to the slave G1 node and the slave G2 node, so that the slave G1 node and the slave G2 node perform user scheduling or frequency switching according to the semi-static spectrum configuration information they receive. Among them, the semi-static spectrum configuration information of the slave G2 node is forwarded by the slave G1 node to the slave G2 node.

[0049] The beneficial effects of the present invention are: (1) by managing single-hop or multiple communication links between nodes, it assists in completing the coordinated management of multiple Star Flash communication domains, while avoiding the interference problem caused by the management nodes that are not within the communication range of the multi-domain management nodes randomly selecting the working frequency band for communication; (2) by introducing static spectrum configuration management methods and semi-static spectrum configuration management methods, thereby reducing the spectrum usage conflicts of adjacent Star Flash communication domains.

[0050] It should be noted that although the above describes the various steps in a specific order, it does not mean that the various steps must be executed in the above specific order. In fact, some of these steps can be executed concurrently or even in a different order as long as the required functions can be achieved.
