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 only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.
Referring to fig. 1, an interaction diagram of a data transmission method provided by an embodiment of the present invention is shown, where the method is applied to a transmission system, and the system includes: a base station and a terminal;
the method comprises the following steps:
s101, when the base station enters a dormancy critical state, the base station sends a dormancy message to a terminal;
in this embodiment, a period of time before the base station switches from the active state to the dormant state is used as the critical dormant state. The time for entering the sleep critical state may be set by a technician based on experience or may be obtained through experiments.
For example, the following steps are carried out: before entering sleep for 120ms, as shown in fig. 2, the base station may send a sleep message to the terminal, where the sleep message carries the remaining time to enter sleep, for example, 120ms.
In this embodiment, the sending of the sleep message to the downlink terminal by the base station may be implemented by downlink broadcast over an air interface.
The critical state of the base station can be determined by the following method:
setting a dormancy critical control timer after the base station is activated;
when the dormancy threshold timer expires, it indicates that the base station enters the dormancy threshold state.
In this embodiment, the sleep message is used to indicate that the terminal enters a sleep critical state, that is, it can be indicated that the base station is about to enter the sleep state.
Or the sleep state includes the remaining time for the base station to enter the sleep state, which is herein denoted as the first remaining time.
In this embodiment, the sleep critical state may be defined as: the time between the end of the sleep critical control timer and the end of the sleep timer.
The dormancy critical control timer is used for indicating whether the base station enters a dormancy critical state or not;
the dormancy timer is used to indicate whether the base station enters a dormant state.
It should be noted that the base station sets the SIT timer after activation, and if the SIT timer is over time, the base station enters the sleep state.
After the sleep critical control timer is started, the following relationship exists between the timing times of the sleep timers:
SIT_Len＝Dactive_Time_Len+r；
wherein, 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 Time of the sleep timer and the Time of the sleep critical control timer.
When the base station enters the critical state, that is, when the sleep critical control timer ends, r may be a remaining time of the base station entering the sleep critical state, which may be represented as a first remaining time, for example.
In this embodiment, after entering the critical sleep state, the base station may send a sleep message to the terminal in the following two ways:
in the first embodiment, when the base station is detected to enter a dormancy critical state, a dormancy message is sent to the terminal;
in this embodiment, when it is detected that the base station enters the sleep critical state, a sleep message is sent to the terminal.
In this case, when it is detected that the base station enters the sleep critical state, the remaining time for the base station to enter the sleep state is T, and then, at this time, a sleep message is transmitted to the terminal.
In the second embodiment, after the base station enters the critical dormancy state, the base station sends a dormancy message to the terminal at a preset frequency;
if the sleep message includes the first remaining time for the base station to enter the sleep mode, for the second embodiment, after the base station enters the critical sleep state, the base station may continuously send the sleep message to the terminal, and the remaining time for the base station to enter the sleep state changes each time the sleep message is sent.
By way of example: when the base station enters a dormancy critical state, the first remaining time for the base station to enter dormancy is T, and then the dormancy message comprises the first remaining time T; when the sleep message is transmitted again after 30ms has elapsed, the first remaining time included in the transmitted sleep message is T-30ms.
S102: after acquiring a sleep message sent by a base station, a terminal determines whether to send an activation frame based on the sleep message and a preset condition before sending an effective signaling;
in this embodiment, after the terminal acquires the sleep message sent by the base station, in order to ensure that the effective signaling sent by the terminal after receiving the sleep message can be relayed by the base station, it is necessary to ensure that the base station is in an activated state when receiving the effective signaling sent by the terminal.
Therefore, in order to ensure that the base station is still in the active state when receiving the effective signaling sent by the terminal after entering the sleep critical state, the terminal may determine whether to send the active frame based on the received sleep message and a preset condition.
The preset condition for determining whether to transmit the activation frame may include multiple conditions, for example, the following two conditions may be included:
1. the preset conditions include: and after receiving the sleep message, the terminal sends an activation frame to the base station before sending the effective signaling.
The preset condition indicates that the terminal needs to send an activation frame to the base station after receiving the sleep message sent by the base station but before sending the effective signaling. Therefore, the base station can be ensured to be in the activated state even if the base station is in or immediately enters the dormant state after receiving the activation frame, so that the relay operation can be normally executed.
2. The preset conditions include: if the second remaining time for the base station to enter the sleep mode is less than or equal to the preset time threshold, sending an activation frame 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 may be implemented in two ways as follows:
determining second remaining time for the base station to enter the dormancy based on first remaining time for the base station to enter the dormancy, sending time of the base station and the current time of the terminal in the dormancy message;
if the base station sends the sleep message to the terminal in the first embodiment, the sleep message may include: a first remaining time for the base station to go to sleep and a transmission time (where the transmission time represents a time at which the base station transmits a sleep message).
However, after receiving the sleep message, the terminal may send valid signaling to the base station for a short time, and then the remaining time for the base station to go to sleep is changed and is no longer the first remaining time received.
Then, based on the above description, when determining the second remaining time, the terminal needs to determine the second remaining time for the base station to go to sleep based on the first remaining time in the sleep message, the transmission time of the base station, and the current time of the terminal.
For example, if 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.
In order to implement the first embodiment in S101 and the first embodiment in S102, it is necessary to set synchronous clocks at the base station and the terminal to ensure time synchronization between the base station and the terminal.
Determining a target sleep message from all received sleep messages in a second mode; taking the first remaining time of the base station entering the sleep mode contained in the target sleep message as a second remaining time; the target sleep message is the latest received sleep message in the received sleep messages;
in this embodiment, because the base station continuously sends the sleep message to the terminal, the terminal may store the sleep message received each time after receiving the sleep message, and when the target sleep message needs to be determined, the latest received sleep message may be selected from all the received sleep messages.
Or, the terminal replaces the historical sleep message with the latest received sleep message after receiving the sleep message each time, so that the latest received sleep message can be directly used as the target sleep message. (the most recently received sleep message corresponds to the latest received sleep message mentioned above)
S103: if the activation frame needs to be sent, sending the activation frame to a base station;
in this embodiment, when the preset condition is that the preset condition is one, after the terminal receives a sleep message sent by the base station, before sending an effective signaling, an activation frame is sent to the base station;
and when the preset condition is a second condition, namely when the second condition is met, namely the second remaining time for the base station to enter the sleep mode is less than or equal to a preset time threshold value, sending an activation frame to the base station.
S104: after receiving an activation frame sent by a terminal, a base station judges whether the base station is in an activation state;
s105: if the base station is in the activated state, resetting the dormancy timer and the dormancy critical control timer; the dormancy timer is used for indicating whether the base station enters a dormancy state, and the dormancy critical control timer is used for indicating whether the base station enters the dormancy critical state;
the dormancy critical control timer is used for indicating whether the base station enters the dormancy critical state, for example, if the dormancy critical control timer is overtime, the base station enters the dormancy critical state; the dormancy timer is used to indicate whether the base station enters the dormant state, for example, if the dormancy timer is timed out, the base station enters the dormant state.
S106: and if the base station is in the dormant state, the base station performs activation operation.
In this embodiment, after the base station receives the active frame, if the base station is not in the sleep state, that is, the base station is still in the active state, in order to prevent the base station from entering the sleep state during the relay operation performed by the base station, sufficient processing time needs to be ensured, so that the sleep timer can be reset.
Or, when the base station receives an activation frame sent by the terminal, the base station is in a dormant state, and then the base station needs to be activated in order to implement the transit service.
In this embodiment, a base station sends a sleep message to a terminal in a critical sleep state, the terminal determines whether to send an activation frame or not by receiving the sleep message sent by the base station and a preset condition, if the activation frame needs to be sent, the activation frame is sent to the base station, and after receiving the activation frame, the base station resets a sleep timer if the base station is in the activation state; and if the base station is in the dormant state, executing activation operation. Therefore, if the terminal sends the effective signaling in the critical dormant state of the base station, the base station is ensured to be in the activated state when the base station receives the effective signaling, and the base station is ensured to realize the transfer of the effective signaling.
Further, the sleep message includes a first remaining time for the base station to go to sleep, and the terminal determines a second remaining time for the base station to go to sleep based on the first remaining time in the received sleep message and determines whether to send an active frame based on the second remaining time for the base station to go to sleep. Therefore, the terminal judges whether to send the activation frame or not by analyzing the remaining time of the base station entering the dormancy state, so that on one hand, when the terminal is about to enter the dormancy state at the base station, the activation frame is sent to the base station to ensure that the base station can be in the activation state when the base station receives an effective signaling. On the other hand, the activation frame does not need to be sent continuously, and the power consumption of the terminal operation is reduced.
Further, after the base station receives the activation frame, the following two situations are included:
in case one, the base station receives an active signaling after receiving an active frame:
the base station transfers the received effective signaling and stops a dormancy timer and a dormancy critical control timer;
after the transfer operation is finished, starting a dormancy timer and a dormancy critical control timer;
if the dormancy critical control timer is overtime, the base station enters a dormancy critical state;
and if the dormancy timer is overtime, the base station enters a dormancy state.
In this embodiment, when the base station performs the relay operation, the dormancy timer and the dormancy critical control timer are stopped, and after the relay operation is finished, when the base station is in an idle state, the dormancy timer and the dormancy critical control timer are started, where the dormancy critical control timer is used to indicate whether the base station enters the dormancy critical state, for example, if the dormancy critical control timer is overtime, the base station enters the dormancy critical state; the dormancy timer is used to indicate whether the base station enters the dormant state, for example, if the dormancy timer is over, the base station enters the dormant state.
In case two, after receiving the activation frame, the base station does not receive the effective signaling:
when the dormancy critical control timer is overtime, the base station enters a dormancy critical state;
and when the dormancy timer is overtime, the base station enters a dormancy state.
Under the condition that the base station does not receive the effective signaling, the base station is in an idle state, the dormancy critical control timer and the dormancy timer run continuously, when the dormancy critical control timer is overtime, the base station enters the dormancy critical state, and when the dormancy timer is overtime, the base station enters the dormancy state.
Referring to fig. 2, a flowchart of a data transmission method provided in an embodiment of the present invention is shown, where in this embodiment, the method is applied to a base station, and the method includes:
s201: when the base station enters a dormancy critical state, the base station sends a dormancy message to the terminal;
the sleep message is used to indicate that the terminal enters a sleep critical state, that is, it may indicate that the terminal is about to enter a sleep state.
Or the sleep state includes the remaining time for the base station to enter the sleep state, here denoted as the first remaining time.
S202: after receiving an activation frame sent by a terminal, a base station judges whether the base station is in an activation state; the activation frame is sent by the terminal when the base station is in a critical dormancy state;
s203: if the base station is still in the activated state, resetting the dormancy timer and the dormancy critical control timer; the dormancy timer is used for indicating whether the base station enters a dormancy state, and the dormancy critical control timer is used for indicating whether the base station enters the dormancy critical state;
s204: and if the base station is in the dormant state, performing activation operation.
In this embodiment, when the base station is in the sleep critical state, the base station sends a sleep message including a first remaining time for entering into sleep to the terminal, so that the base station determines whether to send an active frame before sending an effective signaling based on the received sleep message, resets the sleep timer if the base station receives the active frame in the sleep critical state, and performs an activation operation on the base station if the base station is in the sleep critical state. Therefore, even if the terminal is in the dormancy critical state at the base station, the base station can be ensured to be in the state capable of realizing the transfer.
After the base station receives the activation frame, with reference to fig. 3 on the basis of fig. 2, the processing flow of the data transmission method applied to the base station further includes:
s205: the base station receives the effective signaling after receiving the activation frame, transfers the received effective signaling and stops the dormancy timer and the dormancy critical control timer;
s206: after the transfer operation is finished, starting a dormancy timer and a dormancy critical control timer;
s207: if the dormancy critical control timer is overtime, the base station enters a dormancy critical state;
s208: if the dormancy timer is overtime, the base station enters the dormancy state.
Besides, the method also comprises the following steps:
s209: after receiving the activation frame, the base station does not receive the effective signaling, and when the dormancy critical control timer is overtime, the base station enters the dormancy critical state, and when the dormancy timer is overtime, the base station enters the dormancy state.
In this embodiment, when the base station is in the sleep critical state, the base station sends a sleep message to the terminal, so that the base station determines whether to send an active frame before sending an effective signaling based on the received sleep message, resets the sleep timer if the base station receives the active frame in the sleep critical state, and performs an activation operation on the base station if the base station is in the sleep critical state. Therefore, even if the terminal sends an effective signaling to the base station when the base station is in the dormancy critical state, the base station can ensure the normal realization of the transfer service.
Referring to fig. 4, a schematic diagram of a state transition of a base station provided in an embodiment of the present invention is shown, where the state transition process includes:
when the base station is in a dormant state, if the base station receives an activation frame, activating processing is carried out;
after the base station is activated, starting a dormancy critical state control timer and starting a dormancy timer; time of the sleep timer = time of the sleep critical state control timer + r.
Judging whether the base station receives an effective signaling;
when the base station receives the effective signaling, the base station is switched to a transfer state, and the dormancy timer and the dormancy critical state control timer are stopped;
after the transfer service is finished, entering an idle state;
if the base station does not receive the effective signaling and the dormancy critical state control timer is overtime, sending a dormancy message to the terminal;
if the base station does not receive the effective signaling and the dormancy timer is overtime, the base station enters the dormancy state.
Referring to fig. 5, a schematic flowchart of a data transmission method provided in an embodiment of the present invention is shown, where in this embodiment, the method is applied to a terminal, and the method includes:
s501: after acquiring a sleep message sent by a base station, a terminal determines whether to send an activation frame based on the sleep message and a preset condition before sending an effective signaling;
the preset condition for determining whether to transmit the activation frame may include various conditions, for example, the following two conditions may be included:
1. the preset conditions include: and after receiving the sleep message, the terminal sends an activation frame to the base station before sending the effective signaling.
The preset condition indicates that the terminal needs to send an activation frame to the base station after receiving the sleep message sent by the base station but before sending the effective signaling. Therefore, the base station can be ensured to be in the activated state even if the base station is in or immediately enters the dormant state after receiving the activation frame, so that the relay operation can be normally executed.
