The terminal 102 sends a wireless connection request to the server 104, the terminal 102 establishes a wireless link with the server 104 to perform data interaction, and the terminal 102 receives a wake-up period corresponding to the first timer sent by the server 104.

The terminal 102 may be, but not limited to, various personal computers, notebook computers, smartphones, tablet computers, and portable wearable devices, and the server 104 may be implemented by a stand-alone server or a server cluster composed of a plurality of servers.
In one embodiment, as shown in fig. 2, a data transmission method is provided, and the method is applied to the terminal in fig. 1 for illustration, and includes the following steps:
step 202, a wireless connection request is sent to a server, a wireless link is established with the server to perform data interaction, and a wake-up period corresponding to a first timer sent by the server is received.
With the large-scale commercial use of NB-IOT networks, NB-IOT terminals are also becoming popular in large scale. NB-IOT networks, i.e., narrowband internet of things (Narrow Band Internet of Things, NB-IOT), become an important branch of the internet of everything. The NB-IoT is built in the cellular network, consumes only about 180kHz bandwidth, and can be directly deployed in the GSM network, the UMTS network or the LTE network, so that the deployment cost is reduced, and smooth upgrading is realized. Meanwhile, NB-IoT is also an emerging technology in the IoT field, supporting cellular data connectivity of low power devices in a wide area network, also called Low Power Wide Area Network (LPWAN). NB-IoT supports efficient connections for long standby times, high network connection requirements, and also provides very comprehensive indoor cellular data connection coverage. PSM (Power Saving Mode), i.e. the power saving mode, is an important feature of NB-IoT networks, the principle of which is to allow a terminal to turn off the functions related to signal transceiving and signaling after entering an idle state for a period of time, thereby reducing the power consumption of antennas, radio frequencies, signaling processing, etc. After entering PSM mode, the terminal will not detect whether there is paging data in the downlink, and will exit PSM mode only when the periodicity TAU and the uplink need to send data. Wherein TAU refers to the fact that when a mobile station moves from one TA to another TA, it needs to re-register with the new TA to inform the network to change its stored location information of the mobile station, a procedure called tracking area update (Tracking Area Update, TAU). In order to confirm the location of the mobile station, the LTE network coverage Area will be divided into a number of Tracking Areas (TAs), which function like the Location Area (LA) and Routing Area (RA) of the 3G, is a basic unit for location update and paging in the LTE system. Specifically, after the terminal registers with the NB-IoT network, the terminal may send a wireless connection request to the server, establish a wireless link with the server to perform data interaction, and receive a wake-up period corresponding to the first timer sent by the server. The first timer is a pre-configured timer, and is set to enable the server and the terminal to start the first timer after data interaction is completed, so as to keep synchronous awakening of the server and the terminal. After the terminal registers with the NB-IoT network, the terminal sends a radio connection request to the server, and after the terminal establishes a radio link with the server, the server may send a message to the terminal, for example, through the TCP/UDP protocol, which corresponds to the server sending a default wake-up period of the first timer to the terminal. The NB-IOT network comprises an NB-IOT terminal, an NB-IOT base station, an NB-IOT packet core network, an IOT connection management platform and an industry application server.
In step 204, when the data interaction with the server is completed, a first timer is started to start timing.
The terminal sends a wireless connection request to the server, establishes a wireless link with the server to perform data interaction, and starts the first timer to start timing when the terminal and the server complete data interaction after receiving a wake-up period corresponding to the first timer sent by the server. Specifically, when the terminal and the server complete data interaction, the terminal may start the first timer to start timing according to the wake-up period of the first timer pushed by the server. In addition, the terminal can negotiate the wake-up period corresponding to the first timer with the server through the TCP/UDP protocol, and when the terminal and the server complete data interaction, the terminal can start the first timer to start timing according to the negotiated wake-up period.
And 206, releasing the wireless link, starting a second timer, and entering the energy-saving mode after the second timer is detected to be overtime.
When the terminal and the server finish data interaction, the terminal starts a first timer to start timing, simultaneously releases a wireless link which is currently established, starts a second timer, and enters an energy-saving mode after the terminal detects that the second timer is overtime. The second Timer refers to a Timer (Active Timer) set in the system in the NB-IoT network according to the 3GPP protocol specification, for example, a T3324 Timer in general. Specifically, when the terminal and the server complete data interaction, the terminal starts a first timer to start timing, meanwhile, the terminal releases the currently established wireless link, namely, after the terminal processes the data, the RRC connection is released, the terminal enters an idle state, meanwhile, the terminal starts a second timer, namely, starts a T3324 timer, and when the terminal detects that the T3324 timer is overtime, the terminal enters a PSM mode. After the terminal successfully registers with the NB-IoT network, if the terminal does not receive and transmit data within a period of time, the wireless link is released by the network side, which is determined by the characteristics of the NB-IoT network. The PSM mode is initiated after termination of a data connection or after completion of a periodic TAU. The RRC refers to radio resource control (Radio Resource Control, RRC), also called Radio Resource Management (RRM) or Radio Resource Allocation (RRA), and refers to performing radio resource management, control, and scheduling by a certain policy and means, and under the condition of meeting the requirement of quality of service, fully utilizing limited radio network resources as far as possible, ensuring reaching a planned coverage area, and improving service capacity and resource utilization as far as possible.
Step 208, when the first timer is detected to be overtime, the network station wakes up from the energy-saving mode, sends a tracking area update notification to the network station, re-establishes a wireless link with the server for data interaction, and when the data interaction with the server is completed, restarts the first timer to start timing.
After the terminal enters the energy-saving mode, when the terminal detects that the first timer is overtime, the terminal wakes up from the energy-saving mode, sends a tracking area update notification to the network base station, re-establishes a wireless link with the server for data interaction, and when the data interaction with the server is completed, re-starts the first timer to start timing. The network base station refers to an NB-IOT base station in an NB-IoT network, wherein the NB-IOT base station is a basic unit forming a cellular cell in mobile communication, and mainly completes communication and management functions between a mobile communication network and UE. I.e. NB-IOT user terminal devices connected via the operator network must be within the coverage area of the base station signal in order to communicate. Tracking area update refers to the process of requiring a new location registration at a new TA to inform the network to change its stored location information of the mobile station when the mobile station moves from one TA to another, i.e., tracking area update (Tracking Area Update, TAU). In order to confirm the location of the mobile station, the LTE network coverage Area will be divided into a number of Tracking Areas (TAs), which function like the Location Area (LA) and Routing Area (RA) of the 3G, is a basic unit for location update and paging in the LTE system. The first timer wakes up after expiration in order to allow the terminal to communicate with the server. The terminal sends the tracking area update notification to the network base station to notify the network side that the terminal is awake, and the terminal is in an awake state and can communicate with the server.
In this embodiment, a wireless connection request is sent to a server, a wireless link is established with the server to perform data interaction, and a wake-up period corresponding to a first timer sent by the server is received. When the data interaction with the server is completed, starting a first timer to start timing, releasing the current wireless link, starting a second timer, and entering an energy-saving mode after the second timer is detected to be overtime. When the first timer is detected to be overtime, the network station wakes up from the energy-saving mode, sends a tracking area update notice to the network station, reestablishes a wireless link with the server for data interaction, and restarts the first timer to start timing when the data interaction with the server is completed. Therefore, effective data transmission in a PSM mode can be realized based on the NB-IOT network, the flexibility of data transmission is improved, low power consumption is ensured, meanwhile, data interaction can be effectively carried out, and the problems that a server cannot acquire a terminal state for a long time and cannot interact with the terminal are solved.
In one embodiment, after the wireless link is released and the second timer is started, the method further includes a step of when the second timer does not expire, specifically including:
When the second timer is detected not to be overtime, the timing of the first timer is stopped when the message sent by the server is received.
And when the terminal releases the currently established wireless link, starting a second timer, namely, the terminal enters an idle state. And stopping timing of the first timer when the terminal receives the message sent by the server during the idle state of the terminal, namely when the terminal detects that the second timer does not expire. The terminal can read the message content according to the received message, and execute the corresponding operation according to the message content. Therefore, the terminal and the server can flexibly perform data transmission in the network based on the NB-IOT, and can effectively perform data interaction while ensuring low power consumption.
In one embodiment, after detecting that the first timer expires, the method further includes a step of receiving a message sent by the server, and specifically includes:
and receiving a message sent by the server, initiating a wireless connection request according to the content of the message, and establishing a wireless link with the server to perform data interaction.
When the data interaction with the server is completed, restarting the first timer to start timing.
When the terminal detects that the first timer is overtime, namely, the terminal is in a wake-up period, the terminal can initiate a wireless connection request according to the content of the message when receiving the message sent by the server, and establish a wireless link with the server to perform data interaction. When the terminal and the server complete data interaction, the terminal restarts the first timer to start timing. For example, as shown in fig. 3, a flow chart of a data transmission method corresponding to the terminal side is shown. When the terminal is in the wake-up mode and receives a message sent by the server, the terminal initiates a wireless connection request according to the content of the message, and establishes a wireless link with the server to perform data interaction. When the terminal and the server complete data interaction, the terminal restarts the first timer stopped before, so that the first timer restarts to count time and enters a new wake-up period. Therefore, in the wake-up period, the server can actively inform the terminal to initiate a data connection request in a short message mode, so that data interaction is performed, the problem that the server cannot acquire the state of the terminal for a long time or perform data interaction with the terminal after the terminal enters the PSM mode is solved, and user experience is remarkably improved.
In one embodiment, after detecting that the first timer expires, the method further includes a step of receiving a message sent by the server, and specifically includes:
and receiving a message sent by the server, reconfiguring a wake-up period corresponding to the first timer according to the content of the message, and restarting the first timer to start timing according to the configured wake-up period.
When the terminal detects that the first timer is overtime, the terminal wakes up from the energy-saving mode, sends a tracking area update notice to the network base station, reestablishes a wireless link with the server for data interaction, namely, when the terminal receives a short message sent by the server in the wake-up period, the terminal stops the first timer, reconfigures a wake-up period corresponding to the first timer according to the content of the message sent by the server, and restarts the first timer to start timing according to the configured wake-up period. Therefore, the terminal and the server can negotiate the wake-up period of the first timer, and reconfigure the wake-up period at any time in a short message mode, so that effective data transmission in a PSM mode in the NB-IOT network is realized, and meanwhile, the flexibility of data transmission is improved.
In one embodiment, as shown in fig. 4A, a data transmission method is provided, and the method is applied to the server in fig. 1 for illustration, and includes the following steps:
and step 402, receiving a wireless connection request sent by the terminal, and establishing a wireless link with the terminal to perform data interaction.
Step 404, when the data interaction with the terminal is completed, starting a first timer to start timing.
Step 406, in the timeout period of the first timer, if it is determined that the wake-up period corresponding to the first timer needs to be updated, notifying the terminal to reconfigure the wake-up period corresponding to the first timer by sending a short message, and restarting the first timer according to the reconfigured wake-up period to start timing.
After the server receives the wireless connection request sent by the terminal, the server establishes a wireless link with the terminal to perform data interaction. Fig. 4B is a schematic flow chart of data transmission at the server side. When the server and the terminal complete data interaction, the server starts a first timer to start timing. And if the server judges according to the processed traffic or data quantity during the overtime period of the first timer, and determines that the wake-up period corresponding to the first timer needs to be updated, the server informs the terminal to reconfigure the wake-up period corresponding to the first timer in a manner of sending a short message, and restarts the first timer to start timing according to the reconfigured wake-up period. The server sends a short message to the terminal, and the short message is used for notifying the terminal to reconfigure the wake-up period corresponding to the first timer, so that the terminal reconfigures the wake-up period corresponding to the first timer according to the short message, and also restarts the first timer to start timing according to the reconfigured wake-up period, thereby keeping the wake-up periods of the server and the terminal consistent and realizing synchronous wake-up.
In this embodiment, a wireless link is established with a terminal to perform data interaction by receiving a wireless connection request sent by the terminal. When the data interaction with the terminal is completed, starting a first timer to start timing, and when the first timer is overtime, if the fact that the wake-up period corresponding to the first timer needs to be updated is judged, informing the terminal to reconfigure the wake-up period corresponding to the first timer in a short message sending mode, and restarting the first timer to start timing according to the reconfigured wake-up period. Therefore, effective data transmission in the PSM mode can be realized based on the NB-IOT network, the wake-up period corresponding to the first timer can be modified according to the user requirement, so that the terminal can be flexibly awakened to perform data interaction, and the problem that the server cannot acquire the terminal state for a long time and cannot perform data interaction with the terminal is solved.
In one embodiment, during the first timer timeout period, the method further comprises:
and receiving a wireless connection request initiated by the terminal, wherein the wireless connection request is a wireless connection request sent to the server after the terminal wakes up from the energy-saving mode and sends a tracking area update notification to the network base station.
And according to the wireless connection request initiated by the terminal, reestablishing a wireless link with the terminal to perform data interaction, and restarting the first timer to start timing when the data interaction with the terminal is completed.
And during the timeout period of the first timer, after the server sends the short message to the terminal, the server receives the wireless connection request initiated by the terminal, the service reestablishes a wireless link with the terminal according to the wireless connection request initiated by the terminal to perform data interaction, and when the data interaction with the terminal is completed, the first timer is restarted to start timing. The short message is used for notifying the terminal to initiate a wireless connection request and re-conduct data interaction with the server. The wireless connection request is a wireless connection request sent to a server after the terminal wakes up from the energy-saving mode according to the negotiated wake-up period and sends a tracking area update notification to the network base station. Therefore, the server and the terminal can be kept to wake up synchronously, the problem that the server cannot acquire the state of the terminal for a long time or cannot interact with the terminal after the terminal enters the PSM mode is solved, and user experience is remarkably improved.
In one embodiment, as shown in fig. 4B, a flow chart of the server-side data transmission is shown. After the terminal registers with the NB-IoT network, the terminal may send a wireless connection request to the server, and after the server receives the wireless connection request sent by the terminal, the server establishes a wireless link with the terminal to perform data interaction. After the server establishes a wireless link with the terminal, the server may send the wake-up period of the first timer to the terminal in a message manner, for example, through a TCP/UDP protocol, which is equivalent to that the server sends a default wake-up period of the first timer to the terminal, that is, the terminal receives the wake-up period corresponding to the first timer sent by the server. When the server and the terminal complete data interaction, the server starts a first timer to start timing. And if the server judges that the wake-up period corresponding to the first timer needs to be updated or the server needs to interact with the terminal in the overtime period of the first timer, the server sends a corresponding message to the terminal. If the message is used for informing the terminal to initiate the wireless connection request, the server re-establishes the wireless link with the terminal to perform data interaction according to the received wireless connection request re-initiated after the terminal wakes up from the energy-saving mode, and when the data interaction with the terminal is completed, the server re-starts the first timer to start timing. If the message is used for informing the terminal to reconfigure the wake-up period corresponding to the first timer, the server restarts the first timer to start timing according to the reconfigured wake-up period. The server sends a message to the terminal, wherein the message is used for notifying the terminal to reconfigure the wake-up period corresponding to the first timer, so that the terminal reconfigures the wake-up period corresponding to the first timer according to the short message, and also restarts the first timer to start timing according to the reconfigured wake-up period, thereby keeping the wake-up periods of the server and the terminal consistent and realizing synchronous wake-up.
