Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

According to the air interface design requirements, the new short-distance communication low-power air interface needs to support several communication modes between nodes as shown in Figure 1, where the G node in each communication mode represents the link management node, and the T node represents the terminal (Terminal ) node, the G node can be used to configure link transmission resources between its corresponding T node. Among them, the first method is the unicast (peer-to-peer) method, which is a typical two-node direct connection and mutual transmission, and the functions of the nodes of both communication parties are similar. Compared with the T node, the G node can only perform some simple links on the communication link. Management and control, such as the selection and configuration of the transmission format; the second method is unicast (scheduling) mode, which requires multiple terminal nodes to be able to access a unified management node and keep connected. The management node in this mode is responsible for scheduling each terminal Communication resources of node links to improve resource utilization efficiency; method 3 is a multicast/broadcast transmission method with a feedback mechanism, data packets are sent from a single node to several nodes, and the sending node receives feedback from these receiving nodes Message confirmation; method four is a scheduled direct connection between devices, in which the communication resources between T ₁ and T ₂ are provided by the management node.

Traditional short-distance wireless communication attempts to reduce energy consumption by introducing technologies that reduce transmission power, but sacrifices flexibility and performance at higher transmission rates. Taking Bluetooth as an example, Bluetooth Low-Energy (BLE), by introducing a variety of technologies to reduce transmission power, such as link state machine, asymmetric design, short data packets, low duty cycle, etc., greatly reduces The power consumption of traditional Bluetooth is reduced. Among them, the link layer state machine concept introduced in BLE (Bluetooth Low Energy) can effectively manage and control the link state between nodes, as shown in Figure 2, including ready state (Standby), advertising state (Advertising), scanning Scanning, Initiating, Synchronization, Isochronous Broadcasting and Connection. The introduction of these states can simplify the management mechanism of the Bluetooth link and reduce the high power consumption caused by highly complex management algorithms, but these state definitions sacrifice communication flexibility and performance at higher transmission rates, for example, cannot support Figure 1 The communication methods of mode 2 and mode 4 in China.

In view of this, on the basis of wireless short-distance communication technology supporting high-standard, high-quality wireless communication such as low delay, high reliability, and high data rate, further meet the requirements of related applications for short-distance communication in terms of energy consumption, and at the same time meet the The air interface design requires and supports various communication modes shown in FIG. 1 , and the present application discloses a communication processing method, system and communication node.

The communication processing method disclosed in this application can be applied to communication nodes based on short-distance wireless communication technology. Short-distance wireless communication technology includes but not limited to Bluetooth, Wi-Fi and Starlight 1.0 technologies. Communication nodes can be but not limited to A node composed of terminal devices in fields such as smart terminals, smart homes, or smart manufacturing.

The processing flow of the communication processing method provided in the embodiment of the present application is shown in Figure 3, specifically including:

Step 301. Determine whether the communication node satisfies a state transition condition corresponding to the current node state of the communication node.

According to the characteristics of the short-distance communication physical layer, the embodiment of the present application redefines the basic state of the communication node and the state transition relationship of the link layer, and designs matching state transition conditions and definitions for the state transition relationship between different node states Relevant processing procedures to achieve the purpose of reducing power consumption while meeting flexible and scalable air interface design requirements.

Among them, the node state in the short-distance wireless communication technology is defined as at least including the following two basic states:

a. It is used to represent the first state in which the communication node is turned on and the radio frequency unit of the communication node is turned off.

In this embodiment, the first state is called U state.

This state is the default state after the device where the communication node is located is turned on. In this state, the radio frequency unit is turned off, does not receive or send any wireless signals, and the communication power consumption is 0.

The device where the communication node is located may be, but not limited to, smart phones, smart earphones, smart home appliances and other devices.

b. The radio frequency unit used to characterize the communication node turns on a second state that can be used for sending and receiving wireless signals, and can be used for communication management and control.

In this embodiment, the second state is called G state, and a communication node in this state is regarded as a management node, that is, a G node shown in FIG. 1 .

In this state, the radio frequency unit of the device is turned on and can be used to receive and send wireless signals, and can be used for communication management and control.

Communication nodes correspond to different communication capabilities and different power consumption in different node states. Taking the above-mentioned first state and second state as examples, the communication capability of the first state is lower than that of the second state. The first state The power consumption of is correspondingly lower than the power consumption of the second state.

At the same time, state transition conditions corresponding to different states of the communication nodes are defined. A state transition condition corresponding to a certain node state of the communication node is used to trigger the communication node to transition from this state to another state.

Wherein, the state transition condition corresponding to the first state of the communication node includes at least a first sub-condition for triggering the transition of the communication node from the first state to the second state.

The first sub-condition includes:

Detecting that the communication node initiates a request to send the corresponding service broadcast;

Or, detecting that the communication node initiates a request to send a corresponding paging message;

Or, it is detected that the communication node has received access requests from multiple other communication nodes and communication resource scheduling needs to be performed among the multiple other communication nodes.

If it is detected that the communication node meets any one of the above conditions, then the communication node is deemed to satisfy the first sub-condition.

In the embodiment of the present application, in the current node state where the communication node is located, the state transition control is performed on the communication node by determining whether the communication node satisfies the state transition condition corresponding to its current node state.

Step 302, if the state transition condition corresponding to the current node state is met, control the communication node to the target state.

Wherein, if the communication node satisfies the state transition condition corresponding to its current node state, the communication node is controlled to transition from the current node state to the target state. The target state is the node state indicated by the state transition condition currently satisfied by the communication node.

Taking the current node state of the communication node as the above-mentioned first state as an example, if it is determined that the communication node satisfies the above-mentioned first sub-condition, correspondingly based on the judgment situation, triggering the transition of the communication node from the first state to the first sub-condition indicating turning The second state is to turn on the radio frequency unit of the communication node so that it can be used to send and receive wireless signals, and at the same time configure it to have corresponding communication management and control functions to meet the service broadcast, paging, or Multi-node access and communication resource scheduling requirements between multiple nodes.

Step 303, performing processing matching the above target state on the communication node.

After the condition judgment of the state transition condition controls the communication node to transition from its current node state to the target state, further in the entered target state, the communication node is processed to match the communication capability of the target state.

For example, if the target state is the above-mentioned first state, the radio frequency unit of the communication node is turned off, thereby not performing any wireless signal transceiving processing on the communication node; For communication requirements, the required service broadcasting, paging message transmission, or multi-node access and communication resource scheduling among the accessed nodes are processed on the communication nodes.

The embodiment of the present application is based on the defined node state of high communication capability to meet the requirements of communication nodes for high-standard, high-quality wireless communication such as low delay, high reliability and high data rate, and based on the defined low communication capability Node status to meet the energy consumption requirements of communication technology.

According to the above solution, it can be seen that the communication processing method provided by the present application defines the node state of the communication node, wherein the node state is defined as at least including the first state used to indicate that the communication node is turned on and its radio frequency unit is turned off, and used for The radio frequency unit representing the communication node turns on the second state that can be used to send and receive wireless signals and can be used for communication management and control. Different node states correspond to different communication capabilities and different power consumption. At the same time, set the interval between different node states. conversion condition. On this basis, by controlling the transition of the node status of the communication nodes, the communication capabilities of the nodes are matched with the communication requirements, avoiding the waste of communication capabilities, and achieving the purpose of saving energy consumption. On the basis of high-standard and high-quality wireless communications such as time, high reliability and high data rate, it further meets the requirements of related applications for communication technology in terms of energy consumption.

In an embodiment, optionally, the basic state defined for a communication node may also include any one or more of the following node states:

c. A third state used to represent a power-off of the communication node.

In this embodiment, the third state is called N state.

In this state, the device where the communication node is located is completely powered off, the radio frequency unit is turned off, the device does not provide any services, and the power consumption is 0.

d. It is used to represent the fourth state in which the radio frequency unit of the communication node is turned on and can only be used to send and receive wireless signals.

In this embodiment, the fourth state is called T state, and the communication node in this state is called T node. The T node can communicate with the node in the G state (that is, the G node), and can perform direct communication with another T node after performing necessary configuration (necessary communication resource configuration by the G node), such as, In the fourth manner shown in FIG. 1 , after the _T2 node is configured by the G node, it can communicate with the _T1 node based on the direct connection mode.

The node in the fourth state (T node) satisfies the wireless communication requirements of all communication modes for T nodes in Figure 1, and can provide the wireless communication functions required by the services carried by T nodes in various communication modes, and correspondingly has certain wireless communication capabilities. Power consumption, the specific power consumption value depends on the service requirements and service duration. Under the premise of the same duration, high-definition audio transmission requires high power consumption. Only the transmission of some temperature/humidity and other status data requires only low power consumption.

In the embodiment of the present application, the node state of the communication node is mainly defined as four basic states including the first state (U), the second state (G), the third state (N) and the fourth state (T) as As an example, the scheme of this application will be described.

Among them, the communication capabilities and power consumption of the N, U, T, and G states increase sequentially.

For the above four states, the transition relationship between each state and the corresponding state transition conditions are defined at the same time. Referring to Figure 4, after the device where the communication node is located is turned on (Turn on), the state changes from N to U. After entering this state, the device is in the state where the radio frequency unit is off, that is, there is no communication power consumption state; in order to realize communication, it is necessary to switch the device from the U state to the T or G state based on the request of the upper layer application or the device configuration, that is, according to The actual communication needs of the communication nodes, by upgrading the status of the communication nodes, meet the high-standard and high-quality wireless communication requirements such as low delay, high reliability and high data rate; after that, in the T or G state, when certain conditions are met Returning to the U state, that is, returning to the state of the communication node to meet the requirements of the communication technology in terms of energy consumption and achieve the purpose of reducing power consumption.

Optionally, the second state, that is, the G state, is further divided into multiple sub-states with different communication capabilities/power consumption. Exemplarily, the sub-states of the second state may include two types: primary management state (G _low ) and High management status (G _high ). The communication management and control capability of the communication node in the primary management state is lower than that in the advanced management state, and the power consumption of the communication node in the primary management state is lower than that in the advanced management state.

in:

Primary management state (G _low ): Similar to the T state, it can handle non-broadcast or broadcast data sent to itself or received from other single nodes, and has all the functions of the T state. Compared with the T state, the communication node in the G _low state, It can also control the communication links of multiple T nodes after accessing multiple T nodes. This control is only some simple controls, such as the selection and configuration of the transmission format, so the function of the device in the G _low state The consumption is slightly higher than that of the equipment in the T state.

The communication node in the G _low state can meet the functional requirements for the G node in the mode 1 and mode 3 in Fig. 1. The selection and configuration of the transmission format by the node in the G _low state include but are not limited to modulation/coding methods (such as, Selection and configuration of binary phase shift keying BPSK, quadrature phase shift keying QPSK, etc.).

Advanced management state (G _high ): refers to the state where the communication node is in the advanced communication mode. A node in the G _high state can access multiple T nodes at the same time, and schedule and manage the communication links of multiple T nodes. Compared with G _{In the low} state, since resource scheduling for multiple links is required, a more complex algorithm is required, so the power consumption in the G _high state is slightly higher than that in the G _low state, and the G node in the G _high state can support the second and fourth methods in Figure 1 The functional requirements of the communication mode on the G node.

The scheduling and management of communication links by nodes in the G _high state includes, but is not limited to, the scheduling and configuration of communication resources in the time domain, air domain, frequency domain, and code domain of the communication link in addition to simple transmission format configuration. .

The state transition conditions between states are further introduced below.

(1) Transition conditions from U state to T state

Condition 11: It is detected that the application on the communication node initiates a service request;

Specifically, it can refer to detecting that the upper-layer application of the device where the communication node is located initiates a service request, such as initiating a service request for earphone service, screen projection service, or configuration information synchronization service in smart home based on the user's interactive operation in the upper-layer application.

Based on this condition, the device (T node) that switches to the T state needs to turn on the receiving unit of the radio frequency, and search for the broadcast information from the G node within the coverage area. Once the broadcast information from the G node is detected, and the broadcast information carries all To request system messages related to services (such as screen projection services), the device in the T state continues to initiate a service request (consistent with the service request initiated by the upper-layer application) and establish a connection with the G node.

Condition 12: detecting that the communication node initiates a service request to be discovered;

Based on this condition, the device (T node) that switches to the T state needs to turn on the sending unit of the radio frequency, send a "service request to be discovered" request to the G node within the wireless communication coverage, declare that it wants to be discovered by the G node, and is allowed to communicate with the G node. The G node establishes the connection.

For example, a smart phone/earphone or a smart home appliance, after starting up, triggers the timer (timer) timing based on the pre-configured timing duration, or determines the periodic node based on the pre-configured periodic trigger strategy, and when the timing duration or the periodic node is reached , the device actively initiates a "service request is discovered" request. Once the device detects the request, it switches to the T state, sends the request to the G node within the coverage area, declares that it wants to be discovered by the G node, and is allowed to communicate with the G node. establish connection.

Condition 13: A paging message related to the communication node is received.

For this condition, the communication node needs to temporarily turn on the receiving unit of the radio frequency based on its own pre-configured strategy to receive the paging information of the G node within the coverage area, and determine whether the G node should page the communication node, that is, the communication node Determine whether it is paged by a G node within the coverage area. Once it is found that it is paged, the communication node enters the T state, and makes an access request to the G node that initiated the paging, and establishes a connection with the G node. If it is found to be paged, turn off the receiving unit of the radio frequency, maintain the U state of the communication node, until the node arrives in the next cycle, temporarily turn on the receiving unit of the radio frequency, and perform the above processing.

Optionally, the corresponding timing duration or periodic trigger strategy can be pre-configured in the equipment system, and when the timing information of the timer reaches the configured timing duration, or reaches the set period node, the receiving unit of the radio frequency is temporarily turned on , and receive paging information from G nodes within the coverage area.

This condition 13 is compared with the above condition 12. Under condition 13, the equipment of the communication node passively waits for the paging of the G node, and accesses the G node that initiates paging when there is a G node paging. The node actively initiates a discovery request to the G node within the coverage area, and establishes a connection with the G node.

(2) Transition conditions from U state to G _low state

Condition 21: It is detected that the communication node initiates a request to send the corresponding service broadcast;

Based on this condition, the device (G node) that switches to the G _low state needs to turn on the transmitting unit of the radio frequency and send broadcast information to the coverage area. The broadcast information includes but is not limited to the basic interface required to establish a connection with the device in the G _low state. Input information, and related information about services provided by the device in the G _low state.

Basic access information, including but not limited to the address of the device in the G _low state, ID (Identity document), ID card identification number) and other information; information about the services provided, including but not limited to the information of the device in the G _low state Information such as the service type of the service provided (such as screen projection service, information synchronization service between smart home devices, etc.), service status (such as the maximum number of accesses when accessing a T node, and the current number of accesses, etc.).

Condition 22: It is detected that the communication node initiates a request to send a corresponding paging message.

Based on this condition, the device (G node) that switches to the G _low state needs to turn on the transmitting unit of the radio frequency, send paging information carrying specific T node information to the coverage area to find a specific T node, and turn on the receiving unit of the radio frequency to wait The access request of the paged T node.

The specific T-node information carried in the paging information may include but not limited to information such as the device ID or device address of the T-node.

(3) Conditions for transition from G _low state to G _high state

Condition 31: Access requests from multiple T nodes are received, and communication resource scheduling needs to be performed among the multiple T nodes.

Once a device in the G _low state receives access requests from more T nodes, if the device is configured to support the G _high state, it will accept the access requests of more T nodes and Coordinated scheduling of relevant communication resources between T nodes for data transmission.

In practical applications, optional, according to the actual functional requirements of the node device, it can be configured in the node device whether it is allowed to have the functions of certain node states. For example, in the smart home scene, some edge devices, such as sensors, can be The configuration supports the functions of N, U, T, and G _low states, but does not support the functions of G _high states, and some central devices, such as devices used to synchronize configuration information in smart homes, can be configured to support N, U, and G low states. Function of T and G _low , G _high state.

(4) Transition conditions from G _high state to G _low state

Condition 41: Only communicate with a single T-node or no T-node

A device in the G _high state, once it detects that it only communicates with a single T node or does not communicate with any T node, it will fall back to the G _low state and perform processing that matches the G _low state, such as performing a single link Transmission format control or sending system message broadcast, etc.

For example, in the second mode shown in Figure 1, after the G node completes the communication resource scheduling and control between different T nodes, if it only communicates with a single T node or no T node, it can fall back from the G _high state to the G _low state.

Condition 42: The direct link between different T nodes is established successfully.

A device in the G _high state can switch back to the G _low state after successfully configuring direct connections between different T nodes, and maintain a single-link communication mode with a T node.

For example, in mode 4 shown in FIG. 1, when node G schedules and configures corresponding communication resources (such as frequency domain resources and time domain resources) to node _T2 , and node _T2 establishes communication with node _T1 based on the configured resources. After the direct link, the G node returns from the G _high state to the G _low state.

(5) Conditions for transition from G _low state to U state

Condition 51: the service carried in the G _low state is completed;

A device in the G _low state, once the carried service is completed (for example, the selection and configuration of the link transmission format is completed, and there is no need to communicate with the T node, etc.), and there is currently no follow-up service to be provided, it will be in the G _low state The device falls back to the U state, that is, the radio frequency unit is turned off.

Condition 52: The communication link quality does not meet the quality condition.

Quality conditions can be set by technicians according to actual needs, and the set quality conditions should at least enable the communication quality of the channel to ensure the completion of the required communication.

During the communication process with the T node, if the device in the G _low state detects that the channel communication quality is too poor for a period of time and does not meet the set quality conditions, it will fall back to the U state and turn off the radio frequency unit.

Optionally, if it is detected that the channel communication quality does not meet the set quality conditions within a period of time, the state rollback process can be performed directly, or the transmit power of the radio unit can be further increased. After the communication is completed, choose to return from the G _low state to the U state, and turn off the radio frequency unit.

(6) Transition conditions from T state to U state

Condition 61: the service carried in the T state is completed;

Similar to condition 51, once the service carried by the device in the T state is completed (for example, the required data transmission with the G node or other T nodes is completed), and there is no follow-up service, the device in the T state will fall back To the U state, that is, to turn off the wireless radio frequency unit.

Condition 62: The communication link quality does not meet the quality condition.

Similar to condition 52, if a device in the T state detects that the channel communication quality is too poor for a period of time during communication with other nodes (G nodes or other T nodes), and does not meet the set quality conditions, Then return to the U state and turn off the radio frequency unit.

In practical applications, when it is also detected that the channel communication quality does not meet the set quality conditions for a period of time, the state rollback process is directly performed, or the transmit power of the radio frequency unit is further increased, and the communication cannot be completed by increasing the transmit power. , perform state rollback.

On the basis of the above definition of the node state of the communication node and the transfer relationship between nodes, and setting the state transfer conditions corresponding to the transfer relationship between nodes, referring to Figure 5, the communication processing method disclosed in the present application can be further implemented as:

Step 501. Determine whether the communication node satisfies a first transition condition corresponding to its current node state, and/or whether it satisfies a second transition condition corresponding to its current node state.

The first transition condition is a condition corresponding to the current node state of the communication node and used to trigger the communication node to upgrade its node state.

In contrast to the first transition condition, the second transition condition is a condition corresponding to the current node state of the communication node and used to trigger the communication node to roll back its node state.

Here, "upgrade" means that the communication capability and power consumption of the communication node are improved, and "rollback" means that the communication capability and power consumption of the communication node are reduced.

In this step 501, in the current node state where the communication node is located, determine whether the first transition condition corresponding to its current node state and used to trigger its node state upgrade is satisfied, and/or whether the first transition condition corresponding to its current node state is satisfied. to trigger the second transition condition of its node state rollback. If any one of them is satisfied, the status upgrade or rollback of the communication node will be triggered accordingly.

Step 502, if the first transition condition is met, control the communication node to the first target state.

The first target state is the corresponding state after the current node state of the communication node is upgraded.

That is, when the communication node satisfies the first transition condition corresponding to its current node state and used to trigger its node state upgrade, the state upgrade of the communication node is triggered, and the communication node is converted to the corresponding first target state after the state upgrade.

Step 503, if the second transition condition is satisfied, control the communication node to the second target state.

The second target state is a corresponding state after rolling back the current node state of the communication node.

That is, when the communication node meets the second transition condition corresponding to its current node state and used to trigger its node state rollback, the state rollback of the communication node is triggered, and the communication node is switched to the corresponding second transition condition after the state rollback. target state.

Wherein, it is determined whether the communication node satisfies the first transition condition corresponding to its current node state, and if the first transition condition is met, the communication node is controlled to the first target state, which can be specifically realized as follows:

11) If the current node state of the communication node is the third state (N), determine whether the communication node satisfies the conversion condition from N to U, that is, determine whether the device where the communication node is located is powered on, once it is detected that the device is powered on, switch the communication node from The current N state is upgraded to U state. In the U state, the device is turned on but the radio frequency unit of the device remains off.

12) If the current node state of the communication node is the first state (U), determine whether the communication node satisfies the first sub-condition for triggering the transition of the communication node from the first state (U) to the second state (G), and/or Or whether to meet the second sub-condition for triggering the communication node from the first state (U) to the fourth state (T); if the first sub-condition is met, the communication node is controlled to the second state (G), that is, Turn on the radio frequency unit of the device so that it can be used to send and receive wireless signals, and at the same time provide corresponding wireless scheduling and management functions; if the second sub-condition is met, control the communication node to the fourth state (T), that is, turn on the radio frequency of the device unit so that it can only be used to send and receive wireless signals.

Wherein, for the situation that the second state (G) is further divided into a primary management state (G _low ) and an advanced management state (G _high ), it is determined whether the communication node satisfies the first subcondition, and when it is satisfied, the communication node is controlled as The second state (G) can be further realized as:

First, in the U state, it is determined whether the communication node satisfies the transition condition from the U state to the G _low state, that is, whether any of the following conditions is met: the communication node is detected to initiate a request to send the corresponding service broadcast, and the communication node is detected The node initiates a request to send the corresponding paging message. If it is satisfied, it will trigger the communication node to switch to the G _low state; then, in the G _low state, once it detects that the communication node meets the transition condition from G _low to G _high , it will detect If the communication node satisfies the following condition—the communication node receives access requests from multiple other communication nodes and needs to perform communication resource scheduling among the multiple other communication nodes, then the communication node is further controlled to an advanced management state (G _low ).

The second sub-condition is the transition condition from the U state to the T state described above, which specifically includes: detecting that the application on the communication node initiates a service request, or detecting that the communication node initiates a "service request is found" request, or receiving to a paging message associated with a correspondent node. Thus, in case the communication node is in the first state (U), once it is detected that it satisfies the second sub-condition, the communication node is transferred to the fourth state (T).

On the contrary, in combination with the situation that the second state (G) is further divided into primary management state (G _low ) and advanced management state (G _high ), it is determined whether the communication node satisfies the second transition condition corresponding to its current node state, if Satisfy the second conversion condition, control the communication node to the second target state, which can be specifically realized as:

21) If the current node state of the communication node is the fourth state (T), determine whether the communication node satisfies the transition condition from the T state to the U state, that is, whether any one of the following conditions is satisfied: Complete the currently carried service in the four states, and detect that the current communication quality of the communication node does not meet the quality conditions; if any of the above conditions is met, return the communication node to the first state (U), that is, turn off the radio frequency unit of the device.

22) If the current node state of the communication node is the primary management state (G _low ), determine whether the communication node satisfies the transition condition from the G _low state to the U state, that is, whether any one of the following conditions is satisfied: it is detected that the communication node is in the Complete the currently carried service in the primary management state, and detect that the current communication quality of the communication node does not meet the quality conditions; once it is detected that any of the above conditions is met, the communication node will fall back to the first state (U), that is, turn off the device’s RF unit.

23) If the current node state of the communication node is the advanced management state (G _high ), determine whether the communication node satisfies the transition condition from the G _high state to the G _low state, that is, whether it meets any one of the following conditions: the communication node only communicates with A single communication node communicates or does not communicate with any communication node, and the communication node completes the establishment of direct communication links between other different communication nodes; once it detects that any of the above conditions is met, the communication node returns to the primary management state (G _low ), that is, the control communication node only has simple communication resource management and control functions in addition to the function of the T node, for example, it can only be used for the selection and configuration of the transmission format.

24) If the current node state of the communication node is U, once it is detected that the device where the communication node is located is powered off, the communication node enters the third state (N).

Step 504: Perform processing matching the transition to the first target state or the second target state on the communication node.

After the communication node is controlled to the corresponding target state (such as the first target state or the second target state), in the corresponding target state of the communication node, the process matching the target state it is in is performed.

Wherein, the communication node is processed to match the first target state, which can be specifically implemented as:

31) If the first target state is the first state (U), since in this state, the device where the communication node is located is powered on but its radio frequency unit is turned off, therefore, no communication processing is performed on the communication node (for example, no communication processing is performed) wireless signal transmission and reception), the communication power consumption of the device is 0.

32) If the first target state is the fourth state (T), then based on the current communication requirements of the communication node in the T state, the communication node performs matching communication processing.

Specifically, when it is detected that the application on the communication node initiates a service request, the communication node searches for the broadcast information from the G node within the coverage area. Once the broadcast information from the G node is detected and the broadcast information carries information related to the requested service system message (for example, the carried service type is consistent with the service type requested by the upper-layer application), the communication node (ie, a communication node in T state, or T node) continues to initiate a service request and establish a connection with the G node.

When it is detected that the communication node initiates a "service request to be discovered" request, the communication node sends a "service request to be discovered" request to the G node within the coverage area, declaring that it wants to be discovered by the G node, and is allowed to establish with the G node. connect.

If the communication node receives the paging message related to its own node, such as, the communication node receives the paging message carrying the ID or address of the communication node itself of the G node, in this case, the communication node sends the paging message to G The node makes an access request and establishes a connection with the G node.

33) If the first target state is the primary management state (G _low ), then based on the current communication requirements of the communication node in the G _low state, perform matching communication processing on the communication node.

Specifically, in response to detecting that a communication node initiates a request to send a corresponding service broadcast, the communication node in the G _low state sends broadcast information to the coverage area. The broadcast information includes but is not limited to establishing a service with the communication node in the G _low state. The basic access information required for the connection, and the relevant information about the services provided by the communication node in the G _low state, etc.

Basic access information, including but not limited to the address, ID and other information of the communication node in the G _low state; information about the services provided, including but not limited to the type of service provided by the communication node in the G _low state (such as, Screencasting service, information synchronization service between smart home devices, etc.), service status (such as the maximum number of accessable and current accesses when accessing T devices, etc.) and other information.

When it is detected that a communication node initiates a request to send a corresponding paging message, the communication node in the G _low state sends paging information carrying specific T-node information to the coverage area to find a specific T-node, and turns on the radio frequency The receiving unit waits for an access request from the paged T node.

In combination, refer to FIG. 6(a)-FIG. 6(c) for a schematic flowchart of the state transition of the node under different trigger conditions and the subsequent connection establishment.

Among them, in Fig. 6(a), device 1 in state U triggers a state transition based on the detected request to send the corresponding service broadcast, and enters state G _low , device 2 in state U based on the detected request of the upper layer application The service request transitions to state T, after which, device 2 accesses device 1 by receiving the system broadcast message from device 1, and performs a successful access confirmation.

In Fig. 6(b), device 1 in state U triggers a state transition based on the detected request to send corresponding service broadcast, and enters state G _low , and device 2 in state U transitions to G low based on the detected discovery request. In state T, afterward, device 2 accesses device 1 by receiving an access-related message from device 1, and performs access success confirmation.

In Figure 6(c), device one in state U triggers a state transition based on the detected request for paging a specific node, and enters state G _low , and device two in state U transitions based on the detected request to receive paging After reaching the state T, the device 2 accesses the device 1 by receiving the relevant paging message from the device 1, and performs the confirmation of successful access.

Nodes in the G _low state, in addition to the function of T nodes, can also and can only be used for simple communication resource management and control of communication links, such as the selection and configuration of communication link transmission formats, etc., which can meet the requirements of Fig. Functional requirements for G nodes in mode 1 and mode 3 in 1.

34) If the first target state is the high-level management state (G _high ), then based on the current communication requirements of the communication node in the G _high state, perform matching communication processing on the communication node.

Once a node in the G _low state detects access requests from multiple other communication nodes (that is, multiple T nodes) and needs to perform communication resource scheduling among multiple other communication nodes (multiple T nodes), the state will be triggered Transition into the G _high state, and after the state transition, establish connections with multiple T nodes. The state transition and access process are specifically shown in Figure 7. In Figure 7, Device 2 in the G _low state first connects Device 3, and on this basis, further detects the access request of Device 1. At this time, Device 2 triggers a state transition to enter the G _high state, and continues to access device 1 in the G _high state to establish connections with multiple devices in the T state, that is, multiple T nodes.

The nodes in the G _high state can not only be used for simple communication resource management and control such as the selection and configuration of the communication link transmission format, but also can control the communication link in the time domain, air domain, frequency domain, code domain, etc. Scheduling and configuration of communication resources. Exemplarily, according to the current resource scheduling requirements, the communication resource scheduling process of mode 2 shown in FIG. 1 or the communication resource scheduling process of mode 4 shown in FIG. 1 can be performed on each accessed T node.

For the second method shown in Figure 1, the G _high node can allocate communication resources (such as time domain resources, frequency domain resources, etc. ) is prioritized to be dispatched to one or some T nodes that are accessed, and other T nodes are waiting. After that, after the T node that has allocated resources completes the required processing and releases the communication resources, the released communication resources are scheduled to Other corresponding nodes in waiting state.

For the fourth method shown in Figure 1, after the G _high node establishes a connection with a different T node, it allocates communication resources to a certain T node among the different T nodes that need to establish a direct link, as shown in Figure 8, the The communication resource is allocated to the device 2. For another example, the communication resource is allocated to the node T ₂ in the fourth mode shown in FIG. Establish direct links with other T nodes based on the configured communication resources, and confirm the successful establishment of direct links to the G _high node.

The communication node is processed to match the second target state, which can be specifically implemented as:

41) If the second target state is the first state (U) or the third state (N), since the radio frequency unit of the communication node is turned off in the first state (U) or the third state (N), there is no communication node When performing any communication processing (for example, not performing any wireless signal transmission and reception), the communication power consumption of the device is 0.

42) If the second target state is the primary management state (G _low ), then in the G _low state, only communicate with a single communication node or not communicate with any communication node, or establish direct communication between different T nodes for completion In the case of the link, maintain a communication connection with a T node. As shown in Figure 8, device 1 is completing the establishment of a direct communication link between device 2 and device 3, and the node status returns from G _high to G _low After that, device one continues to maintain the connection with device two.

In this embodiment, according to the actual communication requirements of the communication nodes, the state of the communication nodes is upgraded to meet high-standard and high-quality wireless communication requirements such as low delay, high reliability, and high data rate, and the state of the communication nodes is rolled back. It satisfies the requirements of communication technology in terms of energy consumption and achieves the purpose of reducing power consumption, and the embodiment of the present application defines each basic state of the communication node, the state transition relationship and the state transition condition matching the state transition relationship, which can effectively support the new Various communication methods that need to be supported by the short-range communication low-power air interface provide a flexible and scalable air interface design solution.
