Description

Network equipment communication method, device and storage medium

Technical Field

The present disclosure relates to low-rate wireless personal area networks, and more particularly, to a method and apparatus for network device communication and a storage medium.

Background

A low-rate wireless personal area network, LR-WPAN, is a collection of devices that communicate over the IEEE 802.15.4 standard using the same wireless channel within a personal operating space. According to the strength of the communication capability of the equipment, the equipment can be divided into two types: a Reduced-Function Device (RFD) and a Full-Function Device (FFD). The communication relationship between these two types of devices is: the FFD can directly communicate with the FFD and the RFD, but the RFD and the RFD cannot directly communicate with each other and must be forwarded by the FFD. In the IEEE 802.15.4 standard, an FFD having a forwarding function is referred to as a PAN network coordinator (network coordinator for short). The network coordinator is the master controller in the LR-WPAN and is responsible for tasks such as identification, link management, and packet forwarding, in addition to participating directly in the application. The conventional physical layer technology of the LR-WPAN cannot realize direct communication between RFDs, but the FFD needs too high power consumption, generally, equipment of the Internet of things powered by a battery is difficult to bear, the network coverage is poor, a network coordinator has large load, connection conflict is easy to occur, and the whole capacity of the network is limited.

In the 3GPP standard, a D2D (Device-to-Device) based communication technology is introduced. D2D communication is a technology that allows terminals to directly communicate by multiplexing cell resources under the control of a system, but the conventional D2D communication technology requires the assistance of a cellular system, and cannot realize the function of terminal direct communication in the context of a personal area network.

Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

There are two network topologies according to different needs in the existing LR-WPAN network: a star topology as shown in fig. 1a, and a peer-to-peer topology as shown in fig. 1 b. As described in the background, both of the above two topologies have the disadvantage that the devices cannot communicate directly with each other, and the device 1 in the network shown in fig. 1a wants to communicate with other devices 1 only through the master coordinator 2 therebetween, and the device 1 and other devices 1 shown in fig. 1b can communicate only through the master coordinator 2 and/or the coordinators 3, wherein the master coordinator 2 is the coordinator with the highest authority in the network, and only one master coordinator 2 in each network can manage the other coordinators 3 in the network; the coordinator 3 has lower management authority than the master coordinator 2, and can only manage the devices 1 in the network maintained by the coordinator, but cannot manage other coordinators 3 having the same authority.

In contrast, according to the network device communication method of the present disclosure, the LR-WPAN implemented based on the D2D technology can upgrade two existing network topologies shown in fig. 1a and 1b to: a star mesh topology as shown in fig. 1c, and a peer-to-peer mesh topology as shown in fig. 1 d. In the star mesh topology as shown in fig. 1c and the peer-to-peer mesh topology as shown in fig. 1d, the master coordinator 2 still has only one, and the coordinator 3 still exists only in the peer-to-peer mesh topology as shown in fig. 1d, but the connection relationship between the device 1 and the connection relationship between the device 1 and the coordinator 3 are greatly changed. In the two existing network topologies, the device 1 can only communicate with one master coordinator 2 or one coordinator 3, and therefore can only be connected with one master coordinator 2 or one coordinator 3, and if one device 1 needs to communicate with another device 1, information needs to be forwarded through the master coordinator 2 or the coordinator 3; according to the network device communication method disclosed by the invention, the device 1 and the device 1 in the upgraded mesh topology structure can also be in direct communication, so that the device 1 and the device 1 can also be connected, and one device 1 can also be in direct communication with the plurality of coordinators 3 and the master coordinator 2, so that the two mesh topology structures obtained according to the network device communication method disclosed by the invention have the advantages that the device 1 and the device 1 in the network can be in direct communication, communication contents between the devices 1 do not need to be forwarded through the master coordinator 2 or the coordinators 3 in the network for communication, and the power consumption of the master coordinator 2 and other coordinators 3 in the network is greatly reduced. The difference between the two topologies shown in fig. 1c and fig. 1d is that fig. 1c only includes one master coordinator 2 and several devices 1, and fig. 1d includes several coordinators 3 in addition to one master coordinator 2 and several devices 1 to assist the master coordinator in performing maintenance management on part of the devices 1.

Fig. 2 is a flowchart illustrating a network device communication method according to an exemplary embodiment, which is applied to the device 1 shown in fig. 1c or fig. 1 d. As shown in fig. 2, the network device communication method is used in a low-rate wireless personal area network having a network structure as shown in fig. 1c or as shown in fig. 1d, and includes the following steps.

In step S21, network resource configuration information sent by a coordinator is obtained, where the network resource configuration information includes resource configuration information of all devices in a network maintained by the coordinator and resource configuration information of the coordinator, and the resource configuration information at least includes a monitoring information resource location and a sending information resource location allocated by the coordinator when each device accesses the network.

In a possible real-time manner, the network maintained by the coordinator may be a subnet in a low-rate wireless personal area network, and the coordinator is the coordinator 3 of the subnet, and the coordinator can also directly communicate with the coordinators 3 of other subnets in the low-rate wireless personal area network and the master coordinator 2 in the low-rate wireless personal area network; in another possible real-time approach, the coordinator may also be the master coordinator 2.

The resource allocation information of the device in the network is allocated by the coordinator of the network when the device accesses the network, wherein the resource allocation information at least includes a sending information resource position and a monitoring information resource position, the sending information resource position indicates a resource position where the device sends a signal during communication, and the monitoring information resource position indicates a resource position where the device receives a signal during communication. The time for each device in the network to maintain the receiving state at the position where the device monitors the information resource may be always maintained, or the time may be set to be periodic or event-triggered according to the requirement of the actual application scenario, and if there is a related receiving state time setting, the setting information may also be included in the resource configuration information related to the device in the network resource configuration information.

In step S22, the listening information resource location of the target device is queried according to the network resource configuration information.

In step S23, a paging signal is sent to the target device at the listening information resource location of the target device to establish a link connection with the target device, where the paging signal includes the sending information resource location of the device.

The device in the network can query the monitoring information resource position and the sending information resource position of the target device in the network through the acquired network resource configuration information. One embodiment of a process for sending a paging signal to the target device at the listening information resource location of the target device to establish a link connection with the target device may be as shown in the signal interaction diagram of fig. 3. After acquiring the network resource configuration information sent by the coordinator, the device in fig. 3 may send a PAGING signal, that is, a PAGING signal shown in fig. 3, to the target device according to the monitored information resource location of the target device queried from the PAGING signal, where the PAGING signal further needs to include a sending information resource location of the device, so that the target device can receive data sent by the device at the sending information resource location of the device after the communication link is successfully established; after the target device successfully receives the PAGING signal, the two devices start to attempt to establish a communication link, as shown in fig. 3, the target device may first send a random access preamble to the device, that is, a preamble signal shown in fig. 3, then the device responds to the RAR signal for target device feedback timing and power adjustment, then the target device sends MSG3 to the device, the device sends MSG4 back to the target device, then a communication link is established, and data transmission may be performed between the device and the target device (DATA TRANS), as shown in step S24.

In step S24, after determining that the link connection is established with the target device, data is transmitted to the target device on the transmission information resource location of the device, and data transmitted by the target device is received on the transmission information resource location of the target device.

After the communication link between the device and the target device is established, when the device and the target device communicate with each other, only data transmission needs to be performed at the information resource sending position of the device. The device can acquire the sending information resource position of the target device in the acquired network resource configuration information, so that data sent by the target device can be received at the sending information resource position of the target device, the device already sends the sending information resource position of the device to the target device when sending a PAGING signal to the target device, and the target device can also inquire the sending information resource position of the device from the network resource configuration information sent by the coordinator after knowing the identity of the device, so that the target device can also receive the data sent by the device at the sending information resource position of the device, and data transmission between the device and the target device is realized.

After the data transmission is over, the link may be released by one embodiment as shown in fig. 3, i.e. by sending REL REQ signaling and REL CNF signaling to release the communication link.

Through the technical scheme, the LR-WPAN is improved and realized by adopting the physical layer technology of D2D, and the equipment in the network can realize direct communication with another target equipment in the network through the acquired network resource configuration information, so that the equipment in the network can directly communicate without a coordinator, and the power consumption of the coordinator in the network is greatly reduced.

In one possible embodiment, the method further comprises: and sending the network resource configuration information request to the coordinator. That is, the present device may send a request to the coordinator when the network resource configuration information is needed. Step S21 shown in fig. 2 may include: receiving the network resource configuration information sent by the coordinator through periodic broadcast; or receiving the network resource configuration information sent by the coordinator in response to the network resource configuration information request. That is, the coordinator may broadcast the network resource configuration information to the access device in the network, or may respond to the request of the device in the network and send the network resource configuration information to the requesting device.

The time for the coordinator to maintain the receiving state at the corresponding position of the monitored information resource may be always maintained, or corresponding time setting may be performed on the maintaining time according to an actual application scenario, and if there is a related receiving state maintaining time setting of the coordinator, the time setting information may also be included in the resource configuration information related to the device in the network resource configuration information. When new equipment needs to access a network, the network information resource position periodically broadcasted by a coordinator in a nearby network can be acquired through searching, the monitoring information resource position of the coordinator is acquired from the network information resource position, and network access information is sent to the coordinator to access the network. After receiving the network access information sent by the new network access device, the coordinator allocates a sending information resource location and a monitoring information resource location for the new network access device, or may also set a time for the new network access device to maintain a receiving state at the monitoring information resource location, and updates all configuration information of the new network access device in the network resource configuration information.

In a possible implementation manner, after a new network access device accesses the network, reporting device performance of the device to the coordinator, where the device performance at least includes processing capability and power consumption capability of the device; and reporting the channel quality of the device to the coordinator periodically or event-triggered. This enables the coordinator maintaining the network to obtain the device performance of all the devices in the maintained network, thereby achieving better management and coordination of the devices in the network.

Fig. 4 is a flowchart illustrating a network device communication method according to yet another exemplary embodiment of the present disclosure. As shown in fig. 4, in the case that there is another coordinator capable of communicating with the coordinator, the network resource configuration information further includes resource configuration information of the other coordinator and resource configuration information of devices in another network maintained by the other coordinator, and the method further includes step S41 and step S42.

In step S41, signal evaluation is performed according to the resource configuration information of all the coordinators in the network resource configuration information.

In step S42, according to the result of the signal evaluation, a network maintained by the coordinator with the best signal is selected for access.

The device can acquire the resource configuration information of the coordinator corresponding to the device from the network resource configuration information acquired by the coordinator used for maintaining the device, and can also acquire the resource configuration information of the coordinators of other networks. The resource configuration information may include device performance and channel quality of each coordinator. As shown in fig. 1d, the relationship between the network in which the device is located and other networks may be implemented by using a unique coordinator in each network to implement communication between devices in different networks, where one of the coordinators in each network has the highest authority as a master coordinator, and the device and the coordinator in each network may be managed. The network resource configuration information may be updated after the resource configuration information acquired by the master coordinator from the coordinators in each network, so that the network resource configuration information may include resource configuration information of networks maintained by all coordinators managed by the master coordinator and resource configuration information of networks maintained by the master coordinator, and when a network structure changes, for example, the coordinator is replaced, or devices in the network are increased or decreased, the network resource configuration information may be updated accordingly. The network resource configuration information periodically broadcast to each device in each network by the master coordinator and the coordinators managed by the master coordinator are consistent. The relationship between the networks may be formed by splitting one network, and the specific content will be described in the following.

The coordinator for maintaining the own device may be a master coordinator or a coordinator in a split network, but the network supporting network configuration information transmitted to the own device by either the master coordinator or the coordinator includes the resource configuration information of the coordinator for maintaining the own device and the resource configuration information of all other coordinators capable of communicating with the coordinator for maintaining the own device.

After the network resource configuration information is acquired, the device can respectively perform signal evaluation on corresponding coordinators according to the resource configuration information of all coordinators, and when the coordinator with better signals exists, the device can initiate an access request to the coordinator with better signals again so as to join the network maintained by the coordinator with better signals. Therefore, when the position of the equipment in the network moves or other events causing signal changes occur, the equipment can be intelligently and timely accessed into the network maintained by the coordinator with better signals for the equipment, judgment by the coordinator is not needed, the communication quality of the equipment can be always ensured, and the power consumption of the coordinator of the network where the equipment is located can be reduced.

In one possible embodiment, a network device communication method is provided, which is applied to a master coordinator 2 and/or a coordinator 3 as shown in fig. 1c or fig. 1d, and includes: broadcasting network resource configuration information to all devices in a network maintained by the coordinator, wherein the network resource configuration information comprises resource configuration information of all the devices in the network maintained by the coordinator and resource configuration information of the coordinator, and the resource configuration information at least comprises monitoring information resource positions and sending information resource positions distributed by the coordinator when each device accesses the network. The above steps are applied to the coordinator in the network, that is, the coordinator sends the network resource configuration information to all the devices in the network maintained by the coordinator through periodic broadcast.

Fig. 5 is a flowchart illustrating a network device communication method applied to a coordinator in a low-rate wireless personal area network according to still another exemplary embodiment of the present disclosure, the method including steps S51 and S52.

In step S51, a network resource configuration information request is received.

In step S52, in response to the network resource configuration information request, the network resource configuration information is sent to the device that sent the network resource configuration information request.

In one possible embodiment, the method further comprises: and receiving the device performance and the channel quality reported by all the devices in the network, wherein the device performance comprises processing capacity and power consumption capacity. The device performance may be reported when the device accesses the network as described above, and the channel quality may be reported periodically or event-triggered by the device that has accessed the network as described above.

In addition, in a case where there is a master coordinator having a higher authority than the own coordinator among other coordinators capable of communicating with the own coordinator, that is, in a case where the own coordinator is not a master coordinator, the method further includes: and sending the device performance and the channel quality reported by all the devices in the network, and the device performance and the channel quality of the coordinator to the master coordinator. In this way, after receiving the device performance and the channel quality reported by the devices in the respective networks, the coordinators in the multiple networks managed by the master coordinator can report the device performance and the channel quality to the master coordinator, so that the master coordinator can know the states of all the devices in the networks and the states of all the coordinators in the networks, which are maintained by the coordinators managed by the master coordinator.

In one possible embodiment, the method further comprises: and reallocating the network resources in the network according to the device performance and the channel quality reported by all the devices in the network. For example, when the channel quality of a device in the network maintained by the coordinator is poor, the coordinator may reallocate the corresponding location of the transmission information resource and/or the location of the monitoring information resource to the device, so as to improve the channel quality of the device.

In addition, the method may further include: evaluating the device performance of the coordinator and the device performance reported by all the devices in the network, and under the condition that the preferred device with the device performance higher than that of the coordinator exists, handing over the coordinator authority of the coordinator to the preferred device so as to enable the preferred device to be used as the coordinator in the network. For example, a new device a is added to the network maintained by the coordinator, the device performance reported when the device a enters the network is compared with the device performance of the coordinator itself, and when it is determined that the device performance of the device a is higher than the device performance of the coordinator, the coordinator management authority of the coordinator is handed over to the device a, the device a replaces the coordinator to maintain other devices in the network, and after the coordinator hands over the coordinator management authority, the coordinator becomes a normal device in the network and is maintained by the device a having the coordinator management authority.

When the coordinator is not the master coordinator, after the reallocation of the resources or the handover of the coordinator management authority is executed, the corresponding network structure change information is timely updated to the master coordinator, and then the network resource configuration information is updated, so that the master coordinator, the devices in the network maintained by the master coordinator, the other coordinators managed by the master coordinator and the devices in the network maintained by the other coordinators can acquire the corresponding change information; and under the condition that the coordinator is the main coordinator, the network resource configuration information can be directly updated according to the corresponding change information.

Fig. 6 is a flowchart illustrating a network device communication method according to yet another exemplary embodiment of the present disclosure. As shown in fig. 6, in the case where the present coordinator is the master coordinator, the method further includes step S61 and step S62.

In step S61, the device performance and the channel quality reported by all devices in the network that can communicate with the coordinator and that are lower in authority than all other coordinators of the coordinator, the device performance and the channel quality of all other coordinators, the device performance and the channel quality reported by all devices in the network that are maintained by the coordinator, and the device performance and the channel quality of the coordinator are evaluated.

In step S62, the updated master coordinator and each other coordinator, and the devices in the network respectively maintained by each other coordinator and the master coordinator are determined according to the result of the evaluation, and the network resource configuration information is updated according to the update result.

With the increase of devices added in the network, fading among some devices will increase, and if a master coordinator is used to maintain all the devices, the effect will be poor, so at this time, the network needs to be split into multiple networks, and then a common coordinator with lower authority than the master coordinator needs to be added to maintain the split network, each coordinator maintains a split network, and only one master coordinator still exists. The inside of the split network is still the same as the star mesh network shown in fig. 1c, and the devices can directly communicate with each other without a coordinator, but the communication between two devices in different networks needs to be relayed by the coordinator of the network in which each device is located. Also, the more devices within the network have higher performance requirements on the coordinator, so that it needs to be split every time a network is large to some extent, to form a peer-to-peer mesh network as shown in fig. 1 d.

Since the network structure will change continuously with the increase of devices, the requirements for the coordinator will change continuously, and the requirements for the master coordinator will be higher and higher, the master coordinator needs to evaluate the device performance and channel quality of all devices in the network, so as to select a suitable coordinator or even the master coordinator, to adapt to the changing network structure, and update the coordinator and/or the master coordinator in the network resource configuration information in time.
