The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.

The following briefly describes a body area network architecture, a smart sensor device, a short-range communication technology, and a Relay (Relay) technology related to the present invention.

(1) Body area network architecture

The wireless body area network is a wireless body area network which takes a human body as a center and integrates intelligent sensing equipment and a wireless communication technology. The human body wireless special system is formed by taking sensing equipment and the like around a human body as objects, can be applied to the field of medical health, can also be applied to the fields of consumer electronics, entertainment, military, safety and the like, and fully realizes data connection and intelligent feedback between people and the environment.

As shown in fig. 1, the wireless body area network architecture mainly comprises three parts, that is, (1) an internal network of the wireless body area network, that is, devices such as wearable or implantable sensors around a human body, which mainly complete acquisition and transmission of service data, and is equivalent to a body device node in the embodiment of the present invention; (2) the intelligent analysis system is an information center, namely an intelligent analysis system for storing and managing medical information and the like of health data, mainly completes the release of monitoring tasks, the acquisition of specific data and the like, analyzes and pre-warns the acquired data, and is equivalent to a wireless access node in the embodiment of the invention; the user terminal (3) serving as an information interaction bridge between the (1) and the (2) is controlled by the long-distance external communication base station and the local control network to transmit information and control signaling, and is equivalent to the user terminal node in the embodiment of the invention.

(2) Intelligent sensor device

Body equipment in a body area network is roughly divided into medical application fields and non-medical application fields, and the medical application fields are divided into wearable type, implantable type and remote control type applications according to the arrangement condition of a sensor.

The wireless sensor node in the wearable application is arranged on the surface of clothes or skin of a carrier and used for monitoring information such as body temperature, breathing frequency, motion mode, limb swinging condition and the like of the carrier; the wireless sensor node in the implantable body area network application is implanted into a human body to monitor key health indexes such as health conditions of relevant organs, oxygen content of blood, sugar content and the like; most of wireless sensor nodes in the remote control type are also provided with actuators, and the remote controller can transmit instructions to specific actuators through wireless communication to complete functions of medicine delivery, environment control, early warning/alarming and the like.

Non-medical application fields include consumer electronics, entertainment, sports, environmental intelligence, military and security, etc., for real-time data stream transmission and event processing for interactive entertainment.

(3) Short-range communication technology

The short-distance wireless communication technologies which are applied more in the wireless body area network architecture include ZigBee, Bluetooth and Wi-Fi. The ZigBee has extremely low power consumption and supports star, tree and mesh topological structures. Wi-Fi has higher power consumption and higher cost, but has high transmission rate, and can meet the transmission requirements of various services. The Bluetooth technology greatly increases the reliability in the data transmission process through a series of measures such as error detection and correction, error control, data drying and the like, supports the transmission rate of low power consumption and 1Mbps, and basically meets the transmission rate requirement of medical data.

It should be noted that the above short-range communication technology can only perform data interaction with the wireless access node by means of the user terminal or the adjuster device, and has certain limitations.

The relay technology is to add one or more relay nodes between a base station and a mobile terminal, and is responsible for forwarding a wireless signal once or many times, that is, the wireless signal can reach the mobile terminal through multiple hops. Two-hop relay is to divide a base station-terminal link into two links, namely a base station-relay station and a relay station-terminal, so that a link with poor quality is replaced by two links with better quality, and higher link capacity and better coverage are obtained.

A Relay Node (RN) is connected to its home eNodeB Cell (Donor Cell) by radio.

Fig. 2 is a schematic diagram of an air interface after the introduction of a relay node. As shown in fig. 2, there are three airlinks:

an interface between the RN and a home cell thereof is a Uu interface or a Backhaul Link;

an interface between the R-UE and the RN is a Uu interface or an Access Link (Access Link);

and the interface between the UE and the eNodeB is a Uu interface or Direct Link (Direct Link).

The embodiments of the present invention will be described in further detail with reference to the drawings attached hereto.

As shown in fig. 3, the system structure diagram for data transmission according to the embodiment of the present invention includes: a radio access node 300, a user terminal node 301 and a body equipment node 302.

A wireless access node 300, configured to send a connection establishment request to a body equipment node connected to a user terminal node after receiving a dedicated signaling sent by the user terminal node, where the dedicated signaling is used to indicate that the user terminal node is about to fail or energy is about to be exhausted; after receiving a connection establishment response fed back by the body equipment node, quickly establishing a new connection between the wireless access node and the body equipment node; and after the new connection is established, transmitting data with the body equipment node by using the frequency spectrum resource of the wireless access node.

The user terminal node 301 is used for detecting whether the user terminal node is abnormal or not; and if the abnormality exists, transmitting a special signaling to a wireless access node by using the frequency spectrum resource of the wireless access node connected with the user terminal node, wherein the special signaling is used for indicating that the user terminal node is about to fail or the energy source is about to be exhausted.

A body device node 302, configured to receive a connection establishment request sent by a wireless access node connected to a user terminal node, where the user terminal node is a user terminal node that is about to fail or is about to be depleted of energy; feeding back a connection establishment response to the wireless access node so that the wireless access node quickly establishes a new connection between the wireless access node and the body equipment node; and after the new connection is established, transmitting data with the wireless access node by using the frequency spectrum resource of the wireless access node.

According to the scheme, if the user terminal node detects that the user terminal node is abnormal, the frequency spectrum resource of the wireless access node connected with the user terminal node is used for sending a special signaling to the wireless access node, so that the wireless access node establishes a new connection with a body equipment node after receiving the special signaling, wherein the body equipment node is the body equipment node connected with the user terminal node, and then the wireless access node performs data transmission by using the frequency spectrum resource of the wireless access node after the new connection is established. Therefore, when the user terminal node fails or the energy is exhausted, the information transmission can be continuously carried out between the nodes, and the information transmission rate is improved.

In the body area network, if the user terminal node is not abnormal, the body equipment node sends the collected data to the user terminal node, the user terminal node sends the data to the wireless access node after receiving the data sent by the body equipment node, the wireless access node analyzes the received data and sends an analysis result to the user terminal node, and a user can monitor the body condition according to the analysis result on the user terminal node. If the analysis result is abnormal, the wireless access node can send early warning or alarm information to the user terminal node.

Fig. 4 is a schematic flow chart of data transmission when there is no abnormality in the ue node.

S400, collecting data by body equipment nodes;

s401, the body equipment node sends the acquired data to a user terminal node;

s402, a user terminal node receives data sent by a body equipment node;

s403, the user terminal node sends the received data to the wireless access node;

s404, the wireless access node receives data sent by a user terminal node;

s405, the wireless access node analyzes the received data to obtain an analysis result;

s406, the wireless access node sends the analysis result to the user terminal node, wherein the analysis result comprises early warning/alarm information.

The above is an explanation of data transmission when the user terminal node is not abnormal, and how data transmission is performed when the user terminal node is abnormal will be explained below.

The user terminal detects whether the user terminal is abnormal or not, and if the user terminal is detected to be abnormal, the user terminal sends a special signaling to the wireless access node by using the frequency spectrum resource of the wireless access node connected with the user terminal node, wherein the special signaling is used for indicating that the user terminal node is about to fail or the energy source is about to be exhausted.

When the user terminal node detects whether the user terminal node is abnormal, the user terminal node can detect periodically, for example, the detection is performed once in 1s, and the detection can also be performed in real time.

The abnormality refers to that the user terminal node is about to fail or the energy is about to be exhausted, and after the failure or the energy is exhausted, the user terminal node cannot perform normal communication.

The user terminal node sends a special signaling for indicating that the user terminal node is about to fail or the energy is about to be exhausted to the wireless access node, and the wireless access node establishes connection with a body equipment node connected with the user terminal node to perform data transmission.

In an implementation, the dedicated signaling may include device information of the body device node connected to the user terminal node, such as a device identification of the body device node. And after receiving the equipment identification of the body equipment sent by the user terminal node, the wireless access node determines which body equipment node to establish connection with according to the equipment identification.

The dedicated signaling may also include failure information of the failure of the user terminal node, such as the cause of the failure, the time of the failure, and may enable the periodic detection task to be sent without interruption.

Correspondingly, the wireless access node establishes connection with the body equipment node after receiving the special signaling. Specifically, the wireless access node sends a connection establishment request to the body equipment node, the body equipment node feeds back a connection establishment response to the wireless access node after receiving the connection establishment request, and then the wireless access node quickly establishes a new connection between the wireless access node and the body equipment node.

After the wireless access node establishes a new connection with the body equipment node, the new connection is used, and the spectrum resource of the wireless access node is utilized for data transmission.

The following describes a radio access node using a new connection and transmitting data using the spectrum resources of the radio access node.

After the new connection is established, the wireless access node sends detection task information to the body equipment node by using the frequency spectrum resource of the wireless access node, wherein the detection task information is used for indicating the body equipment node to collect data to be analyzed.

And after the body equipment node receives the detection task information sent by the wireless access node, acquiring the data to be analyzed according to the detection task information.

It should be noted that the detection task information herein may include part or all of the following: detection data information, detection cycle information, and medical method information.

For example, if the detection task information sent by the wireless access node to the body equipment node is detection data information, the data acquired by the body equipment node is data corresponding to the detection data information.

The body equipment nodes in the wireless body area network can be applied to the medical field and also can be applied to the non-medical field, and if the body equipment nodes are applied to the medical field, the detection task information can also be medical method information.

If the method is applied to the medical field, the data to be analyzed comprises the physiological parameter information and/or the time for acquiring the physiological parameter information, and the physiological parameter information and/or the time for acquiring the physiological parameter information are/is sent to the wireless access node, so that the wireless access node can trace the abnormal data conveniently.

When the wireless access node and the body equipment node perform data transmission, after the new connection is established, the wireless access node can also utilize the frequency spectrum resource of the wireless access node to send mobility management information and/or safety information to the body equipment node, so that the unified management and scheduling of the wireless access network on the body equipment node are facilitated.

The body equipment node receives the mobility management information and/or the security information sent by the wireless access node, so that the body equipment node can obtain uniform access and security management.

In the implementation, when the wireless access node and the body equipment node perform data transmission, the spectrum resource of the wireless access node is used. In order to make data transmission more reliable, before the wireless access node establishes a new connection between the wireless access node and the body equipment node, the wireless access node may allocate a dedicated spectrum resource to the body equipment node, so that the wireless access node and the body equipment node use the dedicated spectrum resource for data transmission.

When the wireless access node and the body equipment node transmit data, if the dedicated spectrum resource is occupied, the wireless access node has the highest priority for data transmission with the body equipment node by using other unoccupied spectrum resources of the wireless access node in order to not interrupt data transmission.

Similarly, when the physical device node transmits data with the wireless access node, if the dedicated spectrum resource is occupied, the physical device node enjoys the highest priority for data transmission with the wireless access node using other unoccupied spectrum resources of the wireless access node in order that data transmission is not interrupted.

After receiving the data to be analyzed sent by the body equipment node, the wireless access node analyzes the data to be analyzed, and if the analysis result is abnormal, the wireless access node can give an early warning or alarm to other preset fault-free nodes.

When the user terminal node fails or the energy is exhausted, the early warning or warning information of the wireless access node cannot be received, so that other nodes without faults can be preset to receive the early warning or warning information, and the safety is improved.

The following examples are given by way of illustration.

Example 1:

the body equipment node can communicate with the wireless access node by using the relay user terminal node, and can also directly communicate with the wireless access node.

Fig. 15 is a schematic diagram of a body area network architecture node, as shown in fig. 15, the body area network architecture node includes a wireless access node 1, a body equipment node 2, and a user terminal node 3.

The wireless access node 1 is responsible for connecting the user terminal node 3 or the body equipment node 2 with the network node by using a wireless medium so as to realize information transfer between the user terminal node 3 or the body equipment node 2 and the network.

The body equipment node 2 may be composed of various wireless sensors, medical chips, etc. on the body and is responsible for the acquisition and transmission of human body diversified physiological parameters. The user terminal node 3 serves as a relay node between the wireless access node 1 and the body equipment node 2, and assists in information interaction between the wireless access node 1 and the body equipment node 2.

Under normal conditions, the wireless access node 1 and the body equipment node 2 assist in information interaction by using the relay user terminal node 3. However, when the user terminal node 3 suddenly fails or the energy is about to be exhausted, the wireless access node 1 and the body equipment node 2 directly utilize the spectrum resource of the wireless access node 1 to communicate, record and report the acquired physiological parameter information, and if an abnormal phenomenon occurs, early warning/alarming can be timely carried out.

Example 2:

as shown in fig. 16, a flowchart for recording and reporting a fault event instruction for a user terminal node is shown.

Step 1: normal service data transmission is carried out between the wireless access node 1 and the body equipment node 2 through the relay user terminal node 3, and frequency spectrum resources of the wireless access node 1 are used;

step 2: the user terminal node 3 is about to fail or the energy is about to be exhausted, and the pivot function between the wireless access node 1 and the body equipment node 2 cannot be executed;

and step 3: the user terminal node 3 records the fault information and sends a related special signaling to the wireless access node 1 to indicate the fault event of the user terminal node 3, so that the user terminal node 3 can not assist in message transmission between the wireless access node 1 and the body equipment node 2;

information of the body equipment node 2 to which the user terminal node 3 is connected, which may contain an identification of the body equipment node 2, etc.;

fault information of the user terminal node 3, which may contain the origin of the fault, the time of occurrence of the fault, etc.

And 4, step 4: the wireless access node 1 and the body equipment node 2 establish quick connection, perform data interaction by using the frequency spectrum resource of the wireless access node 1, and directly send a detection task and receive the acquired physiological parameter information;

and 5: the wireless access node 1 receives the detection data collected by the body equipment node 2, analyzes the data in real time, and quickly performs early warning/alarming if the detection is abnormal, acquires professional rescue and ensures personal safety.

Example 3: body equipment node and wireless access node interactive information content

In the wireless body area network communication, the body equipment node and the wireless access node transmit information which can include data information such as detection tasks, detection periods, medical methods and the like issued by the wireless access node side and collected physiological parameter information reported by the body equipment node, wherein the physiological parameter information can include recording time, detection result information and the like and is used for detection, analysis and early warning of physiological parameters of human bodies.

When the user terminal node is about to have sudden abnormity, the transmission information comprises human body sudden abnormity parameter information, such as detection time, abnormal result information and the like, the wireless access node side carries out early warning in time, and a first-aid scheme is adopted by utilizing the time and the parameter information.

Meanwhile, when the user terminal node is about to be abnormal, the information transmitted to the wireless access node can also comprise signaling information such as mobility management, safety and the like, so that the body equipment node obtains uniform access and safety management, and uniform management and scheduling of a wireless access network are facilitated.

Example 4: spectrum resource optimization at wireless access node side

Step 1: in the initial frequency division, the wireless access node 1 allocates a rated dynamic proprietary spectrum resource to the body equipment node 2 in advance, so that the wireless access node 1 and the body equipment node 2 can directly communicate and use the spectrum resource.

Step 2: normally, the body equipment node 2 performs information transmission with the wireless access node 1 through the relay user terminal node 3.

And step 3: under the above conditions, the wireless access node 1 may allocate the dedicated spectrum resource reserved for the body equipment node 2 to other terminals for use, thereby increasing the spectrum utilization rate.

And 4, step 4: when the node 3 is about to fail or the energy is about to be exhausted, the user terminal node 3 sends a related dedicated signaling to the wireless access node 1 to indicate a failure event occurred in the user terminal node 3, and then the user terminal node 3 cannot continue to perform the pivot function of information transmission between the wireless access node 1 and the body equipment node 2.

And 5: the body equipment node 2 utilizes the special spectrum resource allocated by the wireless access node 1 to directly communicate with the body equipment node 2, and if the frequency band resource is occupied by other terminals, the body equipment node 2 enjoys the highest priority and directly uses the same amount of dynamic spectrum resource to directly perform information interaction.
