The terminal 102 may be, but not limited to, various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices, and the server 104 may be implemented by an independent server or a server cluster formed by a plurality of servers.
In an embodiment, as shown in fig. 2, a data transmission method is provided, which is described by taking the application of the method to the terminal in fig. 1 as an example, and includes the following steps:
With the large-scale commercialization of NB-IOT networks, NB-IOT terminals are also becoming widespread on a large scale. The NB-IOT network, Narrow Band Internet of Things (NB-IoT), is an important branch of the world Wide Internet. The NB-IoT is constructed in a cellular network, only consumes about 180kHz bandwidth, and can be directly deployed in a GSM network, a UMTS network or an LTE network so as to reduce the deployment cost and realize smooth upgrading. Meanwhile, NB-IoT is also an emerging technology in the IoT field, supporting cellular data connection of low-power devices in a wide area network, also called low-power wide area network (LPWAN). The NB-IoT supports efficient connectivity for devices with long standby time and high requirements for network connectivity, and can also provide very comprehensive indoor cellular data connectivity coverage. Psm (power Saving mode), i.e. power Saving mode, is an important characteristic of NB-IoT network, and its principle is to allow the terminal to turn off the transceiving of signals and related signaling functions after entering idle state for a period of time, thereby reducing power consumption of antenna, radio frequency, signaling processing, etc. After entering the PSM mode, the terminal does not detect whether the downlink has paging data, and exits the PSM mode only when the periodic TAU and the uplink need to transmit data. The TAU means that when the mobile station moves from one TA to another TA, the location registration needs to be performed again on the new TA to notify the network to change the location information of the mobile station stored in the TA, and this process is Tracking Area Update (TAU). In order to confirm the location of the mobile station, the LTE network coverage Area is divided into many Tracking Areas (TAs), which function like the Location Area (LA) and Routing Area (RA) of 3G and are the basic units for location update and paging in the LTE system. Specifically, after the terminal registers in the NB-IoT network, the terminal may send a wireless connection request to the server, establish a wireless link with the server for data interaction, and receive a wakeup period corresponding to the first timer sent by the server. The first timer is a preconfigured timer and is set to start the first timer after data interaction between the server and the terminal is completed, so as to keep synchronous awakening of the server and the terminal. After the terminal registers in the NB-IoT network, the terminal sends a wireless connection request to the server, and after a wireless link is established with the server, the server may send the wireless connection request to the terminal in a message manner, for example, through a TCP/UDP protocol, which is equivalent 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 grouping core network, an IOT connection management platform and an industry application server.
And step 204, starting a first timer to start timing when the data interaction with the server is completed.
The terminal sends a wireless connection request to the server, establishes a wireless link with the server for data interaction, and starts the first timer to start timing when the terminal and the server finish data interaction after receiving a wakeup 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 a wakeup period of the first timer pushed by the server. In addition, the terminal may negotiate a wakeup period corresponding to the first timer with the server through a TCP/UDP protocol, and when the terminal and the server complete data interaction, the terminal may start the first timer to start timing according to the negotiated wakeup period.
When the terminal and the server finish data interaction, the terminal starts a first timer to start timing, meanwhile, the terminal releases a currently established wireless link, 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 NB-IoT network according to the 3GPP protocol specification, and is typically, for example, a T3324 Timer. Specifically, when the terminal and the server complete data interaction, the terminal starts a first timer to start timing, and at the same time, the terminal releases the currently established radio link, that is, after the terminal finishes processing data, the RRC connection is released, the terminal enters an idle state, and at the same time, the terminal starts a second timer, that is, 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 in the NB-IoT network, if data transceiving does not occur 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 completion of a periodic TAU. The RRC refers to 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 using a certain strategy and means, and under the condition of meeting the requirement of service quality, fully utilizing the limited Radio network resources as much as possible, ensuring that the Radio Resource Control reaches the planned coverage area, and improving the service capacity and the Resource utilization rate as much as possible.
And step 208, after detecting that the first timer is overtime, waking up from the energy-saving mode, sending a tracking area updating notice to the network base station, reestablishing a wireless link with the server for data interaction, and restarting the first timer to start timing when finishing the data interaction with the server.
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 updating notice to the network base 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. The network base station refers to an NB-IOT base station in an NB-IoT network, and the NB-IOT base station is a basic unit forming a cell in mobile communication and mainly completes communication and management functions between a mobile communication network and UE. That is, NB-IOT user terminal devices connected through the operator network must be within the coverage area of the base station signal for communication. Tracking Area Update refers to when a mobile station moves from one TA to another TA, the procedure is Tracking Area Update (TAU) which requires re-location registration on the new TA to inform the network to change the location information of the mobile station it stores. In order to confirm the location of the mobile station, the LTE network coverage Area is divided into many Tracking Areas (TAs), which function like the Location Area (LA) and Routing Area (RA) of 3G and are the basic units for location update and paging in the LTE system. The first timer is awakened after being overtime so as to enable the terminal to communicate with the server. The reason that the terminal sends the tracking area update notification to the network base station is to notify that the network side 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 the server, a wireless link is established with the server to perform data interaction, and a wake-up period corresponding to the first timer sent by the server is received. And 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 detecting that the second timer is overtime. And when the first timer is detected to be overtime, awakening from the energy-saving mode, sending a tracking area updating notice to the network base station, reestablishing a wireless link with the server for data interaction, and restarting the first timer to start timing when the data interaction with the server is completed. Therefore, effective data transmission can be achieved in a PSM mode based on the NB-IOT network, the flexibility of data transmission is improved, low power consumption is guaranteed, meanwhile, data interaction can be effectively conducted, and the problems that a server cannot acquire a terminal state for a long time and cannot conduct data interaction with a terminal are solved.
In one embodiment, after the radio link is released and the second timer is started, the method further includes a step of when the second timer has not timed out, specifically including:
and when the second timer is not detected to be timed out and the message sent by the server is received, stopping the timing of the first timer.
And when the terminal releases the currently established wireless link, the terminal enters an idle state after the second timer is started. And when the terminal is in an idle state, namely when the terminal detects that the second timer is not timed out, the terminal stops timing by the first timer when receiving the message sent by the server. The terminal can read the message content according to the received message, and the terminal executes the corresponding operation according to the message content. Therefore, the terminal and the server can flexibly transmit data in the network based on the NB-IOT, and data interaction can be effectively carried out while low power consumption is ensured.
In one embodiment, after detecting that the first timer times out, the method further includes a step of receiving a message sent by the server, which 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 for data interaction.
And 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, that is, the terminal is in the wake-up period, and the terminal receives the message sent by the server, the terminal can initiate a wireless connection request according to the content of the message, and establish a wireless link with the server for data interaction. And when the terminal and the server finish data interaction, the terminal restarts the first timer to start timing. For example, as shown in fig. 3, it is a flowchart of a data transmission method corresponding to the terminal side. When the terminal is in the wake-up mode and receives the 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 for data interaction. When the terminal and the server finish data interaction, the terminal restarts the first timer which is stopped before, so that the first timer restarts timing and enters a new wake-up period. Therefore, in the awakening period, the server can actively inform the terminal to initiate the data connection request in a short message mode, so that data interaction is performed, the problems that the server cannot acquire the state of the terminal for a long time and cannot perform data interaction with the terminal after the terminal enters the PSM mode are solved, and user experience is remarkably improved.
In one embodiment, after detecting that the first timer times out, the method further includes a step of receiving a message sent by the server, which specifically includes:
and receiving a message sent by the server, reconfiguring a wakeup cycle corresponding to the first timer according to the content of the message, and restarting the first timer to start timing according to the configured wakeup cycle.
When the terminal detects that the first timer is overtime, the terminal wakes up from the energy-saving mode, sends a tracking area updating notice to the network base station, and reestablishes a wireless link with the server for data interaction, namely when the terminal receives a short message sent by the server during the wake-up period, the terminal stops the first timer, and can reconfigure the wake-up period corresponding to the first timer according to the content of the message sent by the server and restart 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 can reconfigure the wake-up period at any time in a short message mode, so that effective data transmission is realized in a PSM mode in an NB-IOT network, and meanwhile, the flexibility of data transmission is improved.
In one embodiment, as shown in fig. 4A, a data transmission method is provided, which is described by taking the method as an example applied to the server in fig. 1, and includes the following steps:
And step 404, when the data interaction with the terminal is completed, starting a first timer to start timing.
And step 406, during 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 to start timing according to the reconfigured wake-up period.
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 server-side data transmission. When the server and the terminal finish data interaction, the server starts a first timer to start timing. And during the timeout period of the first timer, if the server judges according to the processed traffic or data volume and determines that the update operation needs to be carried out on the wake-up period corresponding to the first timer, the server informs the terminal to reconfigure the wake-up period corresponding to the first timer by 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, wherein the short message is used for informing the terminal to reconfigure the awakening period corresponding to the first timer, so that the terminal reconfigures the awakening period corresponding to the first timer according to the short message, and restarts the first timer to start timing according to the reconfigured awakening period, thereby keeping the awakening periods of the server and the terminal consistent, and realizing synchronous awakening.
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 data interaction with the terminal is completed, starting a first timer to start timing, and during the timeout period of the first timer, if the awakening period corresponding to the first timer needs to be updated, notifying the terminal to reconfigure the awakening period corresponding to the first timer in a short message sending mode, and restarting the first timer to start timing according to the reconfigured awakening period. Therefore, effective data transmission can be achieved in a PSM mode based on the NB-IOT network, the awakening period corresponding to the first timer can be modified according to user requirements, the terminal can be awakened flexibly to conduct data interaction, and the problems that a server cannot acquire the state of the terminal for a long time and cannot conduct data interaction with the terminal are 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 the 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 a wireless connection request initiated by the terminal, reestablishing a wireless link with the terminal for 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, when the server sends a short message to the terminal and receives a wireless connection request initiated by the terminal, the service reestablishes a wireless link with the terminal for data interaction according to the wireless connection request initiated by the terminal, and when the data interaction with the terminal is completed, the first timer is restarted to start timing. The short message is used for informing the terminal to initiate a wireless connection request and carrying out data interaction with the server again. The wireless connection request is a wireless connection request which is sent to a server after the terminal wakes up from an energy-saving mode according to a negotiated wake-up period and sends a tracking area update notification to a network base station. Therefore, the server and the terminal can be kept to be awakened synchronously, the problems that the server cannot acquire the state of the terminal for a long time and cannot perform data interaction with the terminal after the terminal enters the PSM mode are solved, and the user experience is remarkably improved.
In one embodiment, as shown in fig. 4B, a flow diagram of server-side data transmission is shown. After the terminal registers in 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 the wireless link with the terminal, the server may send the wakeup period of the first timer to the terminal in a message manner, for example, through a TCP/UDP protocol, which is equivalent to the server sending a default wakeup period of the first timer to the terminal, that is, the terminal receives the wakeup period corresponding to the first timer sent by the server. When the server and the terminal finish data interaction, the server starts a first timer to start timing. And during the overtime period of the first timer, if the server judges that the awakening period corresponding to the first timer needs to be updated or the server needs to perform data interaction with the terminal, 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 reestablishes a wireless link with the terminal for data interaction according to the received wireless connection request initiated again after the terminal is awakened from the energy-saving mode, and restarts the first timer to start timing when the data interaction with the terminal is completed. And if the message is used for informing the terminal to reconfigure the awakening period corresponding to the first timer, the server restarts the first timer according to the reconfigured awakening period to start timing. The server sends a message to the terminal, wherein the message is used for informing the terminal to reconfigure the awakening period corresponding to the first timer, so that the terminal reconfigures the awakening period corresponding to the first timer according to the short message, and restarts the first timer to start timing according to the reconfigured awakening period, thereby keeping the awakening periods of the server and the terminal consistent, and realizing synchronous awakening.
It should be understood that although the various steps in the flow charts of fig. 1-4 are shown in order as indicated by the arrows, the steps are not necessarily performed in order as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise. Moreover, at least some of the steps in fig. 1-4 may include multiple steps or multiple stages, which are not necessarily performed at the same time, but may be performed at different times, which are not necessarily performed in sequence, but may be performed in turn or alternately with other steps or at least some of the other steps.
