Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

Referring to FIG. 1, there is shown an interactive schematic diagram of a data transmission method provided by an embodiment of the present invention. The method is applied to a transmission system, and the system includes: a base station and a terminal;

The method includes:

S101: After the base station enters the critical sleep state, the base station sends a sleep message to the terminal;

In this embodiment, a period of time before the base station transitions from the active state to the dormant state is regarded as the dormant critical state. The time to enter the critical state of sleep can be set by the technician based on experience, or can be obtained through experiments.

For example: before entering sleep for 120 ms, as shown in FIG. 2, the base station sends a sleep message to the terminal, where the sleep message carries the remaining time to enter sleep, for example, 120 ms.

In this embodiment, the base station sending the dormant message to the downstream terminal may be implemented through an air interface downlink broadcast.

The critical state of the base station can be determined in the following ways:

When the base station is activated, set the sleep critical control timer;

When the sleep critical state timer expires, it means that the base station enters the sleep critical state.

In this embodiment, the sleep message is used to indicate that the terminal has entered a critical sleep state, that is, it can indicate that the base station is about to enter the sleep state.

Or the dormant state includes the remaining time for the base station to enter the dormant state, which is represented here as the first remaining time.

In this embodiment, the sleep critical state can be defined as the time between the end of the sleep critical control timer and the end of the sleep timer.

Among them, the sleep critical control timer is used to indicate whether the base station enters the sleep critical state;

The sleep timer is used to indicate whether the base station enters the sleep state.

What needs to know is that after the base station is activated, the SIT timer will be set. If the SIT timer expires, the base station will enter the dormant state.

After the sleep critical control timer is started, the timing time of the sleep timer has the following relationship:

SIT_Len=Dactive_Time_Len+r;

Among them, SIT_Len represents the time of the sleep timer, Dactive_Time_Len represents the time of the sleep critical control timer, and r represents the time interval between the sleep timer and the sleep critical control timer.

Wherein, when the base station enters the critical state, that is, when the sleep critical control timer ends, r may be the remaining time for the base station to enter sleep when the base station enters the sleep critical state, for example, may be expressed as the first remaining time.

In this embodiment, after the base station enters the critical sleep state, it can send sleep messages to the terminal in the following two ways:

Embodiment 1: When it is detected that the base station enters a critical sleep state, a sleep message is sent to the terminal;

In this embodiment, when it is detected that the base station enters a critical sleep state, a sleep message is sent to the terminal.

In this case, when it is detected that the base station enters the critical sleep state, the remaining time for the base station to enter the sleep state is T, then at this time, a sleep message is sent to the terminal.

Embodiment 2: After the base station enters the critical sleep state, the base station sends a sleep message to the terminal at a preset frequency;

Wherein, if the sleep message includes the first remaining time for the base station to enter sleep, for the second embodiment, after the base station enters the critical sleep state, the base station can continuously send sleep messages to the terminal, and each time a sleep message is sent, the base station enters sleep The remaining time of the state will change.

For example: when the base station enters the critical state of sleep, the first remaining time for the base station to enter sleep is T, then the sleep message contains the first remaining time T; after 30ms, the sleep message is sent again, then the sleep message is sent The first remaining time included in the message is T-30ms.

S102: After obtaining the dormant message sent by the base station, the terminal determines whether to send an activation frame based on the dormant message and preset conditions before sending effective signaling;

In this embodiment, after the terminal obtains the dormant message sent by the base station, in order to ensure that the valid signaling sent by the terminal after receiving the dormant message can be transferred by the base station, it is necessary to ensure that the base station is in an active state after receiving the valid signaling sent by the terminal.

Therefore, in order to ensure that after the base station enters the critical sleep state, the base station is still in the active state when it receives valid signaling sent by the terminal, the terminal may determine whether to send an activation frame based on the received sleep message and preset conditions.

Wherein, the preset conditions for determining whether to send the activation frame may include multiple, for example, may include the following two conditions:

1. The preset conditions include: after receiving the sleep message, the terminal sends an activation frame to the base station before sending valid signaling.

The preset condition indicates that after receiving the sleep message sent by the base station, the terminal needs to send an activation frame to the base station before sending valid signaling. In this way, it can be ensured that after the base station receives the activation frame, even if the base station is in or immediately enters the dormant state, it can be transformed into the active state to perform the transfer operation normally.

2. The preset conditions include: the second remaining time when the base station enters sleep is less than or equal to a preset time threshold, then an activation frame is sent to the base station; the second remaining time is determined based on the first remaining time.

In this embodiment, determining the second remaining time based on the first remaining time can be implemented in the following two ways:

Manner 1: Determine the second remaining time for the base station to enter sleep based on the first remaining time for the base station to enter sleep, the sending time of the base station, and the current time of the terminal in the sleep message;

If the base station sends the dormant message to the terminal in the first embodiment, the dormant message may include: the first remaining time for the base station to enter dormancy and the sending time (wherein, the sending time represents the moment when the base station sends the dormant message).

However, after receiving the dormant message, the terminal may send valid signaling to the base station after a short period of time. Then the remaining time for the base station to enter dormancy has changed at this time, and it is no longer the first remaining time received.

Based on the above description, when the terminal determines the second remaining time, it needs to determine the second remaining time for the base station to enter sleep based on the first remaining time in the sleep message, the sending time of the base station, and the current time of the terminal.

For example: assuming that the transmission time of the base station is T, the first remaining time is 120ms, and the current time of the terminal is T+20ms, then the second remaining time is 100ms.

It should be noted that, in order to implement the first embodiment in S101 and the first method in S102, a synchronization clock needs to be set in the base station and the terminal to ensure time synchronization between the base station and the terminal.

Manner 2: Determine the target sleep message from all the received sleep messages; use the first remaining time for the base station to enter sleep included in the target sleep message as the second remaining time; the target sleep message is the latest received sleep message among the received sleep messages Hibernation message that arrives;

In this embodiment, since the base station continuously sends dormant messages to the terminal, after receiving the dormant message, the terminal can save the dormant message received each time. When the target dormant message needs to be determined, it can retrieve all received dormant messages. The latest dormant message received from the dormant message is selected.

Alternatively, each time the terminal receives the sleep message, it replaces the historical sleep message with the latest received sleep message, so that the newly received sleep message can be directly used as the target sleep message. (The sleep message received recently is consistent with the sleep message received at the latest mentioned above)

S103: If an activation frame needs to be sent, send an activation frame to the base station;

In this embodiment, when the preset condition is the above condition 1, after the terminal receives the dormant message sent by the base station, before sending the effective signaling, the terminal sends an activation frame to the base station;

When the preset condition is the second condition, when the second condition is met, that is, if the second remaining time for the base station to enter sleep is less than or equal to the preset time threshold, the activation frame is sent to the base station.

S104: After the base station receives the activation frame sent by the terminal, it determines whether the base station is in an activated state;

S105: If the base station is in the active state, reset the sleep timer and the sleep critical control timer; the sleep timer is used to indicate whether the base station enters the sleep state, and the sleep critical control timer is used to indicate whether the base station enters the sleep critical state;

Among them, the sleep critical control timer is used to indicate whether the base station enters the sleep critical state, for example, the sleep critical control timer expires, the base station enters the sleep critical state; the sleep timer is used to indicate whether the base station enters the sleep state, for example, if the sleep timer expires, then The base station enters a sleep state.

S106: If the base station is in a dormant state, the base station performs an activation operation.

In this embodiment, after the base station receives the activation frame, if the base station is not dormant, that is, the base station is still active, then in order to prevent the base station from going to sleep during the transfer operation, sufficient processing time needs to be guaranteed. The sleep timer is reset.

Or, after the base station receives the activation frame sent by the terminal, the base station is in a dormant state, so in order for the base station to implement the transfer service, the base station needs to be activated.

In this embodiment, the base station sends a sleep message to the terminal in a critical sleep state. The terminal determines whether to send an activation frame by receiving the sleep message sent by the base station and preset conditions. If it needs to send an activation frame, it sends the activation frame to the base station. After receiving the activation frame, if the base station is in the active state, the dormancy timer is reset; if the base station is in the dormant state, the activation operation is performed. In this way, if the terminal sends effective signaling in the critical dormant state of the base station, it is ensured that the base station is in an active state when the base station receives effective signaling, and it is ensured that the base station can realize the transfer of effective signaling.

Further, the sleep message includes the first remaining time for the base station to enter sleep, and the terminal determines the second remaining time for the base station to enter sleep based on the first remaining time in the received sleep message, and determines the second remaining time for the base station to enter sleep based on the second remaining time for the base station to enter sleep. Whether to send an activation frame. Therefore, the terminal determines whether to send an activation frame by analyzing the remaining time when the base station enters sleep. In this way, on the one hand, when the base station is about to enter the sleep state, the terminal sends an activation frame to the base station to ensure that the base station receives a valid signal. The base station can be in the active state at the time of order. On the other hand, there is no need to continuously send activation frames, which reduces the power consumption of the terminal.

Further, after the base station receives the activation frame, the following two situations are also included:

Case 1: The base station receives valid signaling after receiving the activation frame:

The base station performs a transfer operation on the received valid signaling, and stops the sleep timer and the sleep critical control timer;

After the transfer operation ends, start the sleep timer and the sleep critical control timer;

If the sleep critical control timer expires, the base station enters the sleep critical state;

If the sleep timer expires, the base station enters the sleep state.

In this embodiment, when the base station performs the transfer operation, the sleep timer and the sleep critical control timer are stopped. After the transfer operation is completed, when the base station is in an idle state, the sleep timer and the sleep critical control timer are started. The critical control timer is used to indicate whether the base station enters the critical sleep state, for example, the sleep critical control timer expires, the base station enters the sleep critical state; the sleep timer indicates whether the base station enters the sleep state, for example, if the sleep timer expires, the base station enters sleep state.

Case 2: The base station does not receive valid signaling after receiving the activation frame:

When the sleep critical control timer expires, the base station enters the sleep critical state;

When the sleep timer expires, the base station enters the sleep state.

When the base station does not receive valid signaling, the base station is in the idle state, then the sleep critical control timer and sleep timer continue to run, when the sleep critical control timer expires, the base station enters the sleep critical state, when the sleep timer expires , The base station enters the dormant state.

Referring to FIG. 2, there is shown a schematic flowchart of a data transmission method according to an embodiment of the present invention. In this embodiment, the method is applied to a base station, and the method includes:

S201: After the base station enters the sleep critical state, the base station sends a sleep message to the terminal; the sleep critical state is the time between the end of the sleep critical control timer and the end of the sleep timer; the sleep timer is used to indicate whether the base station enters sleep State, the sleep critical control timer is used to indicate whether the base station enters the sleep critical state;

Among them, the dormant message is used to indicate that the terminal has entered a critical dormant state, that is, it can indicate that the terminal is about to enter a dormant state.

Or the dormant state includes the remaining time for the base station to enter the dormant state, which is represented here as the first remaining time.

S202: After the base station receives the activation frame sent by the terminal, it determines whether the base station is in an active state; the activation frame is sent by the terminal when the base station is in a critical sleep state;

S203: If the base station is still active, reset the sleep timer and the sleep critical control timer;

S204: If the base station is in a dormant state, perform an activation operation.

In this implementation, when the base station is in the critical sleep state, it sends a sleep message containing the first remaining time to sleep to the terminal, so that the base station determines whether to send an activation frame before sending valid signaling based on the received sleep message. If the activation frame is received in the dormant critical state, the dormancy timer is reset, and if it is in the dormant state, the base station is activated. In this way, even when the base station is in a critical sleep state, the base station is guaranteed to be in a state capable of realizing transfer.

After the base station receives the activation frame, on the basis of FIG. 2 and referring to FIG. 3, the processing flow of the data transmission method applied to the base station further includes:

S205: The base station receives valid signaling after receiving the activation frame, and the base station performs a transfer operation on the received valid signaling, and stops the sleep timer and the sleep critical control timer;

S206: After the transfer operation ends, start the sleep timer and the sleep critical control timer;

S207: If the sleep critical control timer expires, the base station enters the sleep critical state;

S208: If the sleep timer expires, the base station enters a sleep state.

In addition, it also includes:

S209: After receiving the activation frame, the base station does not receive valid signaling, and when the sleep critical control timer times out, the base station enters the sleep critical state, and when the sleep timer times out, the base station enters the sleep state.

In this implementation, the base station sends a sleep message to the terminal when it is in a sleep critical state, so that the base station determines whether to send an activation frame before sending valid signaling based on the received sleep message. If the base station receives an activation frame in the sleep critical state, Then reset the dormancy timer, and activate the base station if it is in the dormant state. In this way, even if the terminal sends effective signaling to the base station when the base station is in the critical state of sleep, the base station can guarantee the normal realization of the transfer service.

Referring to FIG. 4, a schematic diagram of a state transition of a base station provided by an embodiment of the present invention is shown. The state transition process includes:

When the base station is in the dormant state, if the base station receives an activation frame, it will perform activation processing;

After the base station is activated, it starts the sleep critical state control timer, and starts the sleep timer; the time of the sleep timer=the time of the sleep critical state control timer+r.

Judge whether the base station receives valid signaling;

When the base station receives valid signaling, it will switch to the transit state, stop the sleep timer and the sleep critical state control timer;

After the transfer service ends, enter the idle state;

If the base station does not receive valid signaling and the sleep critical state control timer expires, send a sleep message to the terminal;

If the base station does not receive valid signaling and the sleep timer expires, the base station enters the sleep state.

Referring to FIG. 5, there is shown another schematic flowchart of a data transmission method provided by an embodiment of the present invention. In this embodiment, the method is applied to a terminal, and the method includes:

S501: After obtaining the dormant message sent by the base station, the terminal determines whether to send an activation frame based on the dormant message and preset conditions before sending valid signaling;

The preset conditions for determining whether to send the activation frame may include multiple, for example, may include the following two conditions:

1. The preset conditions include: after receiving the sleep message, the terminal sends an activation frame to the base station before sending valid signaling.

The preset condition indicates that after receiving the sleep message sent by the base station, the terminal needs to send an activation frame to the base station before sending valid signaling. In this way, it can be ensured that after the base station receives the activation frame, even if the base station is in or immediately enters the dormant state, it can be transformed into the active state to perform the transfer operation normally.

2. The preset conditions include: the second remaining time when the base station enters sleep is less than or equal to a preset time threshold, then an activation frame is sent to the base station; the second remaining time is determined based on the first remaining time.

S502: If an activation frame needs to be sent, send an activation frame to the base station;

S503: Send valid signaling to the base station.

In this embodiment, after obtaining the dormant message sent by the base station, the terminal determines whether an activation frame needs to be sent based on a preset condition, so as to ensure that the base station is in an active state after receiving valid signaling. In this way, even if the terminal sends effective signaling to the base station when the base station is in a critical sleep state, it can ensure that the base station can implement a transfer service for effective signaling.

Referring to FIG. 6, there is shown another schematic flowchart of a data transmission method provided by an embodiment of the present invention. In this embodiment, the method is applied to a terminal, and the method includes:

S601: After obtaining the sleep message of the base station, the terminal determines the second remaining time for the base station to enter sleep based on the received sleep message before sending effective signaling;

S602: Determine that the remaining time for the base station to enter sleep in downlink is in relation to a preset time threshold;

S603: If the remaining time for the base station to enter dormancy in downlink is less than or equal to the preset time threshold, send an activation frame to the base station, and send valid signaling to the base station after the activation frame.

S604: If the remaining sleep time of the base station in downlink is greater than a preset time threshold, directly send valid signaling.

In this embodiment, the preset time threshold may be determined by technicians through a lot of experiments. When the time for the base station to enter sleep is less than or equal to the preset time threshold, if the terminal sends valid signaling at this time, the base station receives the After the effective signaling, it may have entered the sleep time, then the transfer service cannot be performed. Therefore, in order to ensure that the base station is in the active state or in the critical dormant state when receiving the effective signaling, it can be sent before the effective signaling is sent. An activation frame.

Or, in this embodiment, further, when the terminal determines that the second remaining time for the base station to enter sleep is greater than a preset time threshold, it directly sends valid signaling.

In this embodiment, if the remaining sleep time of the base station downlink is greater than the preset time threshold, it means that the base station can receive valid signaling before entering the sleep state, and realize the transfer of valid signaling.

In this embodiment, the terminal determines the second remaining time for the base station to enter sleep based on the first remaining time in the sleep message sent by the base station, and determines whether to send the activation frame based on the second remaining time for the base station to enter sleep, so that even if the terminal is in the base station Sending effective signaling to the base station in the critical state of dormancy can also ensure that the base station can realize the transfer of effective signaling.
