Description

Equipment networking state control method, device and medium

Technical Field

The present disclosure relates to wireless internet of things technologies, and in particular, to a method, an apparatus, and a medium for controlling a device networking state.

Background

The wireless networking technology comprising a narrow-band Internet of things (NB-IoT), long-distance radio (LoRa), 5G, a subsequent Next Generation Mobile Network (NGMN) and the like has the advantages of being long-distance, low in power consumption, capable of supporting large-scale networking, ranging, positioning and the like. These wireless networking technologies have enabled the development of the Internet of Things (IoT) from short distances to long distances.

Internet of things (IoT) devices are generally characterized by low throughput, delay tolerance, low power consumption, and the like. In order to realize low power consumption and long-distance transmission, the wake-up period of the new wireless internet of things technology is set to be longer, so that physical layer links do not exist between the internet of things equipment and a core network under a general condition. Only when the terminal has data to send or checks that own service data arrives after the paging cycle arrives, the connection with the network is established.

Taking NB-IoT as an example, in order to achieve low Power consumption, in addition to the connected state (Connect state) and the IDLE state (IDLE state), a new networking state sleep state (PSM) is introduced, that is, the terminal turns off radio frequency reception and enters the sleep state; an eDRX (extended Discontinuous reception) technology is also adopted, and the Discontinuous interception period is prolonged from 2.56s to 2.92 hours; and the updating of the location area with a longer period is defined, and the updating period is prolonged from the current 2 hours of LTE to 310 hours.

Aiming at IoT equipment, the introduction of PSM state (radio frequency reception is turned off by the terminal and the terminal enters dormancy), the eDRX technology and a longer location area updating period greatly save the power consumption of the equipment of the Internet of things.

For example, as a smoke detector of an internet of things device, under a normal condition, in order to save power consumption, the device is in a low power consumption PSM state, that is, the device does not remain a physical link with an IoT core network, and the device may enter an idle state or even a sleep state. But sometimes the internet of things equipment may encounter some emergency, which requires communication connection with the core 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 embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.

Sometimes, some emergency state can be met by the equipment of the internet of things. For example, when a smoke detector serving as the internet of things device detects smoke, the smoke detector cannot simply report the state and then stays in a dormant state for a long time. Instead of sleeping immediately after reporting data according to a normal flow, the networking state with the core network needs to be maintained in a connection state so as to communicate with the background server in real time.

It is desirable that the IoT device in the emergency state can maintain a real-time connection state with the core network and further with a subsequent application server behind the core network, and report various data in the emergency state in real time, so as to prevent the IoT device from entering a long-time dormant state.

The connection state between the IoT device and the wireless base station is divided into a Connect state, a PSM state, and an IDLE state. Wherein the Connect state belongs to the connected state, and the PSM state and the IDLE state both belong to the unconnected state. The device enters an IDLE state if it does not receive and transmit data for a long time in the Connect state, and enters a PSM state if the IDLE state lasts for a certain time. These three states are briefly described below.

Connection state: there is an actual physical link between the IoT device in the Connect state and the wireless base station, the core network and the background server. The equipment in the Connect state can receive and transmit data instantly.

IDLE state: the IoT device in the IDLE state may periodically receive a page from the base station, but cannot directly transmit and receive data. If data is to be transmitted or received, the state of Connect is required to be entered first.

PSM status: the IoT device in the PSM state cannot directly transmit and receive data and cannot receive paging from the base station. And only after the PSM sleep cycle is ended or when the IoT equipment has data to send, switching to the Connect state to further realize data receiving and sending.

When the IoT device transmits data in the IDLE state or PSM state, it automatically switches to the Connect state. When the IoT device transmits data in the Connect state, the networking state switch timer is caused to reset.

The disclosure provides a device networking state control method. When the equipment is in an emergency mode and the networking state is a non-connection state, switching the networking state of the equipment into a connection state; the equipment is kept in the connection state with the core network by transmitting data to the server in the connection state, and the real-time existence of a physical link is ensured, so that the UE can transmit the data in the emergency state outwards with the lowest time delay. The method can ensure that the IoT equipment does not enter a dormant state or an idle state in an emergency state, so that the IoT equipment and the core network and the background server thereof keep a real-time and low-delay connection state.

The IoT devices are, for example, smoke detectors, smart meters, shared bicycles, and other internet of things devices.

Fig. 1 is a flowchart illustrating a device networking state control method according to an exemplary embodiment, as shown in fig. 1, the method comprising the steps of:

step 101, when the device is in an emergency mode, obtaining a networking state of the device and a core network, wherein the emergency mode is a working mode in which the device needs to be connected with the core network;

step 102, when the networking state is a non-connection state, switching the networking state of the equipment to a connection state;

step 103, during the period that the equipment is in the connection state, determining whether the equipment is to be switched to the non-connection state within a set time period;

and 104, when determining that the device is to be switched to the non-connection state in a set time period, sending set data to the core network.

In step 101, when the device detects an abnormal condition, the device is considered to enter an emergency mode. The emergency mode is an operational mode in which the device needs to maintain a connection with the core network. For example, when a smoke detector detects the presence of smoke, an emergency mode is entered; and when the shared bicycle monitors that the positioning is abnormal, the shared bicycle enters an emergency mode. Since the device cannot report data to the server in real time in the Idle state and the PSM state, the device needs to keep its networking state in the Connect state in order to report various data in the emergency state in real time when the device monitors an abnormal condition.

In step 102, when the device is in the emergency mode, the networking state of the device and the core network is obtained, if the networking state of the device is the non-connection state, the device is switched to the connection state, and then step 103 is executed; if the device networking status is the connection status, step 103 is directly executed. Here, the unconnected state includes the IDLE state and the PSM state described above.

In step 103, when the device is in the connected state, it is determined whether the device will be switched to the disconnected state within the set time period, so as to intervene in time to prevent the device from being switched to the disconnected state when it is determined that the device will be switched to the disconnected state.

In step 104, when the device is to be switched to the non-connected state within the set time period, the device is enabled to maintain the connected state by sending the set data to the core network, that is, sending the data to the server through the core network.

It can be seen that in the above method, when the device is in the emergency mode, if the device networking state is not the connection state, the device is switched to the connection state, and in the connection state, when it is determined that the device is to be switched to the non-connection state, the device is sent data to the server through the core network, so as to be maintained in the connection state. By the method, the IoT equipment is ensured not to enter the dormant state or the idle state in the emergency state, so that the IoT equipment and the core network and the background server thereof keep a real-time and low-delay connection state. The setting data here may be data that is set in advance but has no clear meaning.

In an alternative embodiment, the determining whether the device is to be switched to the non-connected state within a set period of time includes:

As can be seen from the foregoing, when a device sends data to the core network, it causes the network state switching timer to reset. That is, when data is transmitted in the connected state, the timing of switching from the connected state to the disconnected state is restarted. Therefore, in this embodiment, it is first determined whether the device has data to be transmitted to the core network, and if so, the networking state switching timer is reset along with the transmission of the data, so that the device can be maintained in the connected state for the next timing period. If there is no data to be sent to the core network, it needs to be determined whether the device is switched to the disconnected state within a set time period. Of course, in the case of data to be transmitted to the core network, it is not necessary to determine whether the device is switched to the non-connected state within a set time period.

Here, the data to be sent to the core network may be data sensed by the device to be reported to the server. For example, when the device is a smoke detector, the data to be sent to the core network is smoke concentration data and smoke temperature data detected by the detector through a sensor, and the like.

In an optional embodiment, the triggering the switching of the device from the connected state to the disconnected state within a set time period includes:

It is known to switch from a connected state to a disconnected state by a device, in one case via the following process: after the device receives and transmits data, if no data interaction lasts for a first time period in the connection state, the device enters an idle state, and if no data interaction lasts for a second time period in the idle state, the device enters a sleep state. The first time period and the second time period are clocked here by a timer. Therefore, the determination of whether the switching from the connected state to the disconnected state is triggered within the set time period can be realized by determining whether the networking state switching timer triggers the switching from the connected state to the disconnected state within the set time period. The set time period here may take a value between 500ms and 2 s. For example, when taking 1s, it is determined whether the networking state switching timer will reach the switching time within 1 s.

In an alternative embodiment, the method further comprises:

After sending the setup data to the core network, the networking state switch timer is reset to restart a new switch time period. This ensures that the device remains connected for the next timing period.

When the device is in the emergency mode and the networking state of the device is the connection state, whether the device is to perform networking state switching or not can be judged at set time intervals, that is, whether the device is to perform networking state switching or not can be judged at set periods. Here, the set period is a timer period that is smaller than the period at which the device switches from the connected state to the disconnected state.

In an alternative embodiment, the non-connected state includes an idle state and a dormant state.

As described above, the non-connected state includes an IDLE state (IDLE state) and a dormant state (PSM state).

Specific embodiments according to the present disclosure are described below in conjunction with specific application scenarios. In this embodiment, the IoT device is a smoke detector. And when the smoke detector detects smoke, entering an emergency mode. The method of this embodiment comprises the steps of:

step 201, the smoke detector detects smoke and determines to enter an emergency mode.

Step 202, obtaining the networking state of the smoke detector and the core network.

Step 203, the networking state is an idle state, and the networking state is switched to a connection state.

Step 204, periodically determining whether the smoke detector needs to send detection data, wherein the period is less than the timing period for switching the smoke detector from the connection state to the disconnection state.

Step 205, if yes, sending, if not, judging whether the state switching timer in the 1s intranet reaches the switching time.

Step 206, when determining that the networking state switching timer triggers switching from the connection state to the disconnection state within 1s, sending a preset data packet to the core network.

Step 207, reset the networking state switch timer to a maximum value.

When the device is in the emergency mode, in the connected state, preset data is periodically transmitted to periodically reset the networking state switching timer.

The present disclosure also provides an apparatus networking state control device, as shown in fig. 3, the device includes:

a state obtaining module 301, configured to obtain a networking state of the device and a core network when the device is in an emergency mode, where the emergency mode is a working mode in which the device needs to maintain a connection with the core network;
