Description
Technical Field
The present invention relates to the field of mobile communications technologies, and in particular, to a data sending method, device, medium, and apparatus based on an NBIOT protocol.
Background
In the related art, to confirm the location of a mobile terminal, an NBIoT (narrowband internet of things) network coverage Area is divided into a number of TAs (Tracking areas), which are basic units of location update and paging in an NBIoT system. The tracking area is identified by a TAC (Tracking Area Code, TA code), which may contain one or more cells, the TAC being broadcast in SIB1 of these cells, and the network being operated with a TAI (tracking area identification) as the unique identification of the TA.
When a mobile terminal moves from one tracking area to another, it must re-register with the new tracking area to inform the network to change the mobile station's location information it stores, a TAU (Tracking Area Update ).
In Tracking Area Update (TAU), if there is no user data and control plane data already buffered, the parameter "Signalling active flag" (SAF) in the TAU Request signaling data is set to 0 in IE (information element): additionalupdate type value (AUTV), and the connection between the terminal device and the new tracking area is released after the terminal device completes the tracking area update without maintaining RRC (radio resource control (RadioResource Control)) connection after the tracking area update procedure is completed.
For the above reasons, if the mobile terminal needs to send data during the tracking area update process, since the TAU procedure has already been started, and if the terminal device does not have the cached user data and control plane data before the TAU procedure starts, the mobile terminal will immediately release RRC after the TAU procedure is completed, and the mobile terminal does not have resources to send data, so that the data is discarded.
The user is unaware of the TAU procedure, if the moment when the user sends the data is exactly within the TAU update time period, the user considers that the data is sent because the data sent by the user is discarded after the TAU procedure is finished, but in fact, the data is not sent, thus unnecessary loss is possibly caused for the user, and the user experience is affected.

Detailed Description
For the purposes of making the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure. It should be noted that, in the case of no conflict, the embodiments and features in the embodiments may be arbitrarily combined with each other.
In order to solve the problem that in the prior art, when a user terminal sends target data in a tracking area updating period, after the tracking area is ended, RRC connection between the terminal equipment and a new tracking area is released, so that the target data is discarded, the application provides a data sending method based on an NBIOT protocol.
The data transmission method based on the NBIOT protocol is applied to terminal equipment, wherein the terminal equipment is electronic equipment with a mobile communication function, such as a mobile phone, a tablet personal computer with a mobile communication function and the like.
Fig. 1 is a flowchart illustrating a data transmission method based on an NBIOT protocol, according to an exemplary embodiment. Referring to fig. 1, the data transmission method based on the NBIOT protocol includes the steps of:
step S11, receiving indication information from a user, wherein the indication information indicates transmission target data;
the user can connect the wireless network at any time and any place by using the mobile terminal device, and enjoys the convenience brought by the network. With the development of network technology and the popularization of various application software, the demands for users to transmit and receive various data through terminal devices are becoming more and more common.
When the user opens the APP in the terminal device, selects data to be transmitted (for example, transmitting a picture), or inputs data to be transmitted (for example, editing a text), clicks a "transmit" button on the terminal, and generates instruction information of the transmission target data. After receiving the indication information, the terminal equipment enters a flow for sending target data.
Step S12, judging whether the terminal equipment is updating the tracking area.
In this embodiment, after receiving the instruction information for transmitting the target data, the terminal device does not immediately transmit the target data, but detects whether the terminal device is performing tracking area update.
More and more users use terminal devices in a mobile scenario, and the mobile process may span different tracking areas. Mobility is a main feature of a wireless communication system, and connection between a terminal device and a wireless network is achieved through handover of a tracking area. In the prior art, data is sent in the tracking area updating process, so that the situation that the data is discarded easily occurs, and therefore, the terminal equipment firstly judges whether the tracking area updating is performed or not, and adopts a corresponding method according to the judging result.
Step S13, if the terminal equipment is updating the tracking area, the target data is cached.
When the terminal equipment judges that tracking area update is being performed, the terminal equipment is stated to be executing a TAU flow, in order to prevent the terminal equipment from releasing RRC after the TAU flow is completed, the target data is discarded, and the terminal equipment does not immediately send the target data, but firstly caches the target data.
Step S14, after the tracking area update is determined to be finished, the target data is sent.
And after the terminal equipment determines that the tracking area is updated, the terminal equipment transmits the target data again, so that the target data is ensured not to be discarded.
In this real-time example, the terminal device determines that the time when the indication information of the target data sent by the user is received, and the TAU procedure is started, but the TAU procedure is not completed, the target data to be sent at this time is buffered first, and then sent after the TAU procedure is completed, so that it is possible to prevent the data from being discarded due to the release of RRC connection after the TAU procedure is completed. Ensuring that the target data is accurately transmitted after the user clicks the transmit button. In addition, as the TAU updating process is very short, the target data is sent after waiting for the TAU updating to finish, the waiting time of the user is not obviously increased, the user is unaware, and the user experience can be effectively improved.
In an exemplary embodiment, the data transmission method based on the NBIOT protocol further includes:
and if the detection result is that the terminal equipment does not update the tracking area, immediately transmitting the target data.
If the terminal device does not perform tracking area update, the terminal device can immediately transmit the target data. At this time, since the tracking area update is not involved, the target data can be smoothly sent out. Even if the terminal device enters the target tracking area from the source tracking area and needs to update the tracking area in the process of sending the target data, the terminal device can set the parameter 'Signallingactive flag' (SAF) in IE (information element): additional Update Type Value (AUTV) in the TAU Request signaling data to be 1 according to the existing NBIOT protocol when sending the TAU Request message because the data moment of sending the target data is located before the TAU update flow, and after the tracking area update process is completed, the connection of the RRC is maintained, so that the terminal device can maintain the service state of the current sending target data, and after the TAU flow is finished, the target data is continuously sent, without discarding the target data.
In an exemplary embodiment, determining whether the terminal device is performing a tracking area update includes:
and if the current time is in the tracking area updating period, judging that the terminal equipment is carrying out tracking area updating, wherein the tracking area updating period is from the time when the terminal equipment initiates the RRC connection establishment request to the time when the tracking area updating issued by the network is received or refused.
When the terminal equipment enters the target tracking area from the source tracking area, the source tracking area sends RRC connection reconfiguration information to the terminal equipment, the information comprises target tracking area identification TAI, and after receiving the RRC connection reconfiguration information sent by the source tracking area, the terminal equipment deletes the current wireless link and detects the target tracking area. And then the terminal equipment accesses the target tracking area, and after the RRC connection reestablishment is completed, the terminal equipment sends an RRC reestablishment completion message to the target tracking area to indicate the completion of the RRC connection reestablishment. Therefore, the time from the time when the terminal device initiates the RRC establishment request to the time when the terminal device receives the tracking area update issued by the network is received or rejected may be used as the tracking area update period. The terminal device may determine that the current period belongs to the tracking area update period when detecting that the RRC connection establishment request is initiated, but no message is received that the tracking area update issued by the network is received or rejected. And the terminal equipment detects that the moment of sending the target data is in the tracking area updating period and judges that the terminal equipment is updating the tracking area.
In an exemplary embodiment, the data transmission method based on the NBIOT protocol, after determining that the tracking area update is finished, includes:
detecting whether the RRC connection with the target tracking area is released or not, and if the RRC connection is not released, transmitting the target data through the RRC connection; and if the RRC connection is released, sending a control plane service request to reestablish the RRC connection and sending the target data.
When the terminal device determines that the tracking area update is finished, the terminal device further comprises detecting whether the RRC connection with the target tracking area is released or not before transmitting the target data.
When the terminal device receives instruction information to transmit target data, the terminal device detects that it is within the tracking area update period, and the TUA flow has started to be executed. But before the TUA procedure the terminal device may be in an idle state, and may be transmitting data or have buffered user data and control plane data.
If the terminal equipment is in an idle state before TUA process, after the terminal equipment and the target tracking area establish connection, the newly-built RRC connection is released, the terminal equipment detects whether the RRC connection is released, if the detection result is that the RRC connection is released, a control plane service request is triggered, the RRC connection is re-established, and the target data is sent through the newly-built RRC connection.
If the terminal device is in a state of transmitting data or having cached user data and control plane data before the TUA flow, the terminal device can maintain the new RRC connection after establishing connection with the new tracking area, and the terminal device can directly transmit the target data without re-establishing the RRC connection.
In an exemplary embodiment, determining whether the terminal device is performing a tracking area update includes:
and acquiring the value of the parameter of the signal activation mark in the transmitted signaling data, and judging that the terminal equipment is updating the tracking area if the value of the parameter of the signal activation mark is 0.
When the terminal transmits the TAU Request message, if the terminal device is in an idle state, a parameter 'Signalling active flag' (SAF) in IE (information element): additionalupdate type value (AUTV) in TAU Request signaling data is set to 0, so that it can be judged that the terminal device is performing tracking area update by acquiring a value of the parameter SAF in the transmitted signaling data, if the value of SAF is 0.
It is noted that if the terminal acquires the value of the parameter SAF in the transmitted signaling data, if the value of SAF is 1, the terminal is in fact also performing the tracking area update at this time. According to the foregoing description, when the value of SAF is 1, after the terminal device and the new tracking area establish a connection, a new RRC connection will be maintained, and the problem that the data sent by the user is discarded after the tracking area update is completed due to the tracking area update is not occurred. Therefore, in the data transmission method based on the NBIOT protocol disclosed in the present application, the tracking area update performed by the terminal device in the case where the value of SAF is 1 may be omitted.
In an exemplary embodiment, after determining that the tracking area update is over, transmitting the target data includes:
and after receiving the RRC release message issued by the network, the terminal equipment sends a control plane service request to reestablish the RRC connection and sends the target data.
On the basis that the terminal equipment is judged to be updating the tracking area by acquiring the value of the parameter SAF in the signaling data, if the value of the SAF is 0, after the terminal equipment completes the TUA flow, the RRC connection with the target tracking area is necessarily released first, and the terminal equipment needs to send a control plane service request to reestablish the RRC connection and send the target data.
In the implementation, the terminal device may wait for the release of the RRC connection after receiving the RRC release message issued by the network, or wait for a predetermined period of time, and initiate a request again and reestablish the RRC connection after ensuring that the RRC connection between the terminal device and the target tracking area is released.
