Currently, LPWA (Low Power Wide Area) technology introduces a deep sleep state. The deep sleep state is carried out by controlling the terminal of the Internet of things, so that the power consumption of the terminal of the Internet of things is effectively reduced.
Disclosure of Invention
The inventor finds that, when the terminal of the internet of things is in a deep sleep state, the terminal of the internet of things cannot receive downlink messages, namely, the terminal cannot be reached. To solve this problem, the following two approaches are generally adopted:
the first method is as follows: after the service platform receives the downlink message, the terminal is determined to send the downlink message when being capable of receiving the downlink message according to the base station inactivity timer. Because the service platform cannot know the actual state of the terminal, the downlink message cannot be sent to the terminal in time.
The second method comprises the following steps: and in the case that the terminal is not reachable, delivering by a repeated transmission mode. This may result in the service platform needing to send multiple times, and the success rate of one-time delivery is low. In addition, if the deep sleep time of the terminal is long, the terminal cannot successfully transmit the downlink message within the specified retransmission times, which may cause a complete failure of downlink message transmission of the service platform.

Fig. 1 is an exemplary flowchart of a downlink packet transmission method according to an embodiment of the present disclosure. In some embodiments, the method steps of this embodiment may be performed by a downlink message transmitting apparatus.
In step 101, downlink message information sent to the user terminal by the network side is received.
In step 102, the current state of the user terminal is determined according to the working state parameters reported by the user terminal.
Executing step 103 under the condition that the user terminal is currently in a downlink reachable state; if the ue is currently in the downlink unreachable state, step 104 is executed.
In some embodiments, the operational status parameters include a Tracking Area Update (TAU) Timer parameter and an activation Timer (Active Timer) parameter.
During one TAU timer period, the terminal is in an idle state during the active timer period, where the terminal can receive downlink data, and is in a PSM (Power Saving Mode) state during the rest of the TAU timer period, where the terminal is in an unreachable state.
In some embodiments, if the ue is currently in an idle state, it is determined that the ue is currently in a downlink reachable state. And if the user is in the power saving mode state at present, determining that the user terminal is in a downlink unreachable state at present.
In step 103, the downlink message is sent to the user terminal.
In step 104, waiting for the user terminal to enter a downlink reachable state;
in step 105, the downlink message is sent to the user terminal when the user terminal enters the downlink reachable state.
In the downlink packet sending method provided by the above embodiment of the present disclosure, the current state of the terminal is determined by using the working state parameter reported by the terminal, so that the downlink packet can be sent under the condition that the terminal can receive the downlink packet, thereby improving the sending efficiency of the downlink packet.
Fig. 2 is a schematic diagram of an embodiment of an operating state of a user terminal according to the present disclosure. As shown in fig. 2, if the terminal is in an idle state, it indicates that the terminal can receive the downlink data at this time, and in this case, the platform can send the downlink data to the terminal. If the terminal is in the PSM state, it indicates that the terminal cannot receive the downlink data at this time, in this case, the platform waits for the terminal to enter the next idle period, and after the terminal enters the next idle period, the platform sends the downlink data to the terminal again.
Fig. 3 is an exemplary flowchart of a downlink packet transmission method according to another embodiment of the present disclosure. In some embodiments, the method steps of this embodiment may be performed by a downlink message transmitting apparatus.
In step 301, downlink message information sent to the user terminal by the network side is received.
In step 302, it is determined whether the ue is currently in an idle state according to the working state parameters reported by the ue.
If the user terminal is currently in an idle state, executing step 303; if the user is currently in the power saving mode, step 307 is executed.
In some embodiments, if the ue further introduces an eDRX (extended Discontinuous Reception) mechanism in the idle state, the operating state parameters further include an eDRX Paging cycle and a Paging Time Window (PTW) period. By utilizing the eDRX mechanism, the power consumption of the terminal can be further reduced.
In step 303, determining whether the ue is currently in a paging time window period of an eDRX paging cycle;
if the ue is currently in the paging time window period of the eDRX paging cycle, go to step 304; if the ue is currently in the non-paging time window period of the eDRX paging cycle, step 305 is executed.
In step 304, it is determined that the ue is currently in a downlink reachable state, and a downlink packet is sent to the ue.
In step 305, it is determined that the ue is currently in a downlink unreachable state, and waits for the ue to enter the next eDRX paging cycle.
In step 306, the downlink message is sent to the ue during the paging time window period in the next eDRX paging cycle.
In step 307, it is determined that the ue is currently in the downlink unreachable state, and waits for the ue to enter the next idle state.
In case the user terminal enters the next idle state, step 303 is performed.
Fig. 4 is a schematic diagram of another embodiment of the working state of the user terminal according to the disclosure. As shown in fig. 4, an eDRX mechanism is also introduced in the idle state of the terminal. That is, the idle state cycle is further divided into a plurality of eDRX paging cycles. A PTW cycle is included in each eDRX paging cycle. Wherein the terminal is capable of receiving downlink messages in the PTW period of each eDRX paging cycle. And the terminal cannot receive the downlink message in the non-PTW period of the eDRX paging period. In this case, the platform waits for the PTW cycle of the next eDRX paging cycle in the idle state to perform downlink packet transmission.
For example, if the time that the service platform receives the last uplink message from the terminal is L, the current time of the platform is N, the corresponding base station inactivity timer parameter is NA, and the TAU timer parameter is TAU, the time parameter T is calculated by using the formula T = MOD [ (N-L-NA)/TAU ]. If T < Active timer parameter, then deeming terminal in idle state, otherwise deeming terminal in PSM state, platform waits (TAUT-T) and then sends down message.
Further, the time parameter D is calculated using the formula D = MOD [ T/eRDX paging cycle ]. If D is less than PTW period, the terminal is determined to be accessible, otherwise, the terminal is determined to be inaccessible, and the platform sends down message after waiting (eRDX paging period-D).
