Specifically, in the NB-IoT/GSM multimode dual-standby terminal, data transmission service can be preferentially provided for the terminal through the NB-IoT network, and short message service, voice service, and supplementary data coverage service can be provided for the terminal through the GSM network. Compared with the method of providing data transmission and voice call service completely based on the GSM network, the NB-IoT optimizes the Power Saving performance on the protocol, namely, a Power Saving Mode (PSM) is introduced, and certain Power consumption can be saved compared with the GSM network during data transmission. Therefore, the NB-IoT/GSM multimode dual-standby terminal can have better power saving performance while ensuring the service continuity.
However, when the NB-IoT/GSM multimode dual standby terminal is in the NB-IoT mode, once the PSM state is entered, the NB-IoT receiving module is turned off, so that downlink data sent by the NB-IoT network cannot be received in the period, and the downlink data is not reachable.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, an embodiment of the present invention provides a data sending method, which is applied to a platform server, and the method includes the following steps:
step 101: and sending downlink data to be sent to the terminal through the GSM short message, or sending indication information to the terminal through the GSM short message or the GSM signaling.
The indication information is used for triggering the terminal to establish the NB-IoT connection to receive downlink data to be sent. The terminal may support both GSM mode and NB-IoT mode.
Specifically, the sending of the downlink data to be sent to the terminal through the GSM short message may be understood as transmitting the downlink data through a GSM short message function. When the indication information is sent to the terminal through the GSM short message or the GSM signaling, the GSM short message can be understood as a wake-up short message, and the GSM signaling can be signaling such as a GSM paging message. And after receiving the indication information, the terminal can actively establish NB-IoT connection with the corresponding network for data transceiving.
In the embodiment of the invention, the downlink data to be sent is sent to the terminal through the GSM short message, or the indication information is sent to the terminal through the GSM short message or the GSM signaling, and the indication information is used for triggering the terminal to establish the NB-IoT connection to receive the downlink data to be sent, so that the NB-IoT/GSM multimode dual standby terminal can still receive the downlink data when being in a downlink unreachable state, and the downlink data can be guaranteed to be reachable in time.
Furthermore, with the help of the scheme of the embodiment of the invention, the PSM can be configured to achieve better electricity saving performance and ensure timely accessibility of downlink data, thereby solving the contradiction between the electricity saving effect and the downlink data transmission delay.
In the embodiment of the invention, when downlink data need to be sent to the NB-IoT/GSM multimode dual-standby terminal, the platform server can perform logic judgment according to the data service type, the data volume to be issued, the power consumption and other factors, namely, judge whether the downlink data is directly issued through GSM short messages or trigger the terminal to establish NB-IoT connection through the GSM short messages or GSM signaling to receive the downlink data.
Optionally, the step 101 may include:
when the downlink data to be issued needs to be fed back by the terminal, sending indication information to the terminal through a GSM short message or a GSM signaling;
alternatively, the first and second electrodes may be,
when the downlink data to be issued does not need to be fed back by the terminal and the data volume of the downlink data to be issued is less than or equal to a preset threshold value, sending the downlink data to be issued to the terminal through a GSM short message;
alternatively, the first and second electrodes may be,
when the downlink data to be issued does not need to be fed back by the terminal and the data volume of the downlink data to be issued is larger than a preset threshold value, sending indication information to the terminal through a GSM (global system for mobile communications) short message or a GSM signaling;
the condition that the terminal needs to perform feedback on the downlink data to be transmitted can be understood that the terminal needs to perform subsequent uplink transmission on a data service (such as a remote location request service) corresponding to the downlink data to be transmitted. The downlink data to be transmitted does not need to be fed back by the terminal, which can be understood as that the data service (such as single downlink service) corresponding to the downlink data to be transmitted does not need to be subsequently uplink-transmitted by the terminal. The preset threshold may be preset according to an actual situation, for example, the preset threshold may be the maximum capacity of one or N short messages, the unit is byte, and N is a positive integer greater than 1.
In the embodiment of the invention, in order to accurately determine whether downlink data needs to be directly sent down through a GSM short message function or trigger the NB-IoT/GSM multimode dual standby terminal to actively establish NB-IoT connection, the platform server can firstly judge whether the terminal is in a downlink unreachable state when the downlink data needs to be sent to the terminal, and executes corresponding operation when the terminal is in the downlink unreachable state.
Optionally, before the step 101, the method may include:
judging whether the terminal is in a downlink unreachable state;
and when the terminal is in a downlink unreachable state, sending the downlink data to be issued to the terminal through a GSM (global system for mobile communications) short message, or sending the indication information to the terminal through the GSM short message or a GSM signaling.
Therefore, by judging whether the terminal is in a downlink unreachable state or not, the platform server can accurately determine whether downlink data needs to be directly issued through a GSM short message function or trigger the NB-IoT/GSM multimode dual-standby terminal to actively establish NB-IoT connection or not.
Further, the determining whether the terminal is in the downlink unreachable state may include:
judging whether the terminal is in a PSM state or not according to the value of a timer T3324 negotiated by the terminal and the platform server recently and the time of successfully receiving or sending data for the last time by the terminal;
and when the time interval between the last successful data receiving or transmitting time and the current time of the terminal exceeds the value of T3324, determining that the terminal is in the PSM state, otherwise, determining that the terminal is not in the PSM state.
It can be understood that the above-mentioned T3324 is a timer for the terminal to enter the PSM state from the Idle state Idle. And the terminal may negotiate a configuration value of T3324 with the network side in an attachment and location Area Update (TAU) procedure. When the terminal is in the PSM state, i.e., in the downlink unreachable state.
Or, the determining whether the terminal is in the downlink unreachable state may include:
judging whether the terminal overtimes and does not respond to the downlink data sent by the platform server;
when the terminal does not respond to the downlink data issued by the platform server after overtime, the terminal is determined to be in the downlink unreachable state, otherwise, the terminal is determined not to be in the downlink unreachable state. That is, when judging whether the terminal is in the downlink unreachable state, the platform server can directly issue downlink data to the terminal, and if the terminal does not respond after time out, the terminal is determined to be in the downlink unreachable state.
For example, the NB-IoT/GSM dual-mode dual-standby smart watch is in an NB-IoT and GSM common coverage area, and preferentially uses the NB-IoT to provide data services and uses the GSM to provide voice services. The smart watch and network complete one data transfer at 13:00 and no data transfer for the T3324 timer time (e.g., 64s), the smart watch enters PSM state.
If the platform server has a remote positioning request to send to the smart watch in a ratio of 13:30 and needs the smart watch to immediately report the current position information, the platform server may first determine that the terminal is in a PSM state (i.e., a downlink unreachable state) according to the time (13:00) of the last data transmission of the smart watch and the value (64s) of T3324, that is, the time interval between the last successful data transmission time of the smart watch and the current time exceeds the value of T3324, and then issue a remote positioning request message to the smart watch through a GSM short message to trigger the smart watch to establish an NB-IoT connection to upload the current position information.
Or, if the platform server has the short message notification information (16 bytes) to send to the smart watch in 13:30, and the smart watch does not need to perform uplink transmission subsequently, the platform server may first determine that the terminal is in the PSM state (i.e., downlink unreachable state) according to the time (13:00) of the last data transmission of the smart watch and the value (64s) of T3324, that is, the time interval between the last successful data transmission time of the smart watch and the current time exceeds the value of T3324, and then select the GSM short message to directly send the short message notification information to the smart watch according to the data service type (no need to perform uplink transmission subsequently) and the downlink data amount (16 bytes, which does not exceed a preset threshold, such as a maximum capacity of the short message).
Referring to fig. 2, an embodiment of the present invention further provides a data receiving method, which is applied to a terminal, where the terminal supports a GSM mode and an NB-IoT mode simultaneously, and the method includes the following steps:
step 201: and receiving downlink data to be issued sent by the platform server through the GSM short message, or receiving indication information sent by the platform server through the GSM short message or the GSM signaling.
The indication information is used for triggering the terminal to establish the NB-IoT connection to receive downlink data to be sent. When the indication information is sent to the terminal through the GSM short message or the GSM signaling, the GSM short message can be understood as a wake-up short message, and the GSM signaling can be signaling such as a GSM paging message.
In the embodiment of the invention, the receiving platform server receives the downlink data to be transmitted sent through the GSM short message, or receives the indication information sent by the platform server through the GSM short message or the GSM signaling, and the indication information is used for triggering the terminal to establish the NB-IoT connection to receive the downlink data to be transmitted, so that the NB-IoT/GSM multimode dual standby terminal can still receive the downlink data when being in a downlink unreachable state, and the downlink data can be ensured to be accessible in time.
Furthermore, with the help of the scheme of the embodiment of the invention, the PSM can be configured to achieve better electricity saving performance and ensure timely accessibility of downlink data, thereby solving the contradiction between the electricity saving effect and the downlink data transmission delay.
