The technical solutions in the embodiments of the present invention are 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 embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.

Embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

As shown in fig. 1, an embodiment of the present invention provides a DRX control method, including:

11. and acquiring data volume information of data transmitted by the user terminal UE.

12. And when the data volume information is determined to be lower than the corresponding first preset threshold, sending first control information to the UE, wherein the first control information is used for indicating the UE to enter a Discontinuous Reception (DRX) state.

The execution main body of the DRX control method of the embodiment of the invention can be a base station, such as an eNodeB of an LTE system.

The DRX control method according to the embodiments of the present invention may also be applied to other systems, such as UMTS (Universal mobile telecommunications System), in an extended manner, and the execution main body of the DRX control method according to the embodiments of the present invention may be a Node B, or the execution main body may be a base station controller, such as an RNC (Radio network controller). The method of the embodiment of the invention is suitable for various systems with similar problems, and the embodiment of the invention does not limit the specific systems.

Those skilled in the art will appreciate that when the UE enters the DRX state, the UE does not have to continuously listen to the PDCCH channel and the UE can turn off its transceiver to achieve power saving.

In step 12, the base station may carry the first Control information through an RRC (Radio Resource Control) message.

Optionally, the manner for the first control information to indicate the UE to enter the DRX state may include:

the first control information may further include a DRX parameter, and when the setup field of the RRC message carries the DRX parameter of the first control information, the UE is instructed to enter the DRX state.

Or, the first control information may further include an indication bit, and when the RRC message carries the indication bit, the UE is indicated to enter the DRX state, and the message carrying the indication bit may be an existing message or an added message, which is not limited in this embodiment of the present invention. In addition, the DRX parameter may be carried by a setup field of the RRC message.

The DRX state corresponding to the DRX parameter comprises the following steps: the UE monitors a PDCCH (physical Downlink control channel) in the active period and does not monitor the PDCCH in the dormant period, so that the UE can turn off a transceiver thereof to achieve the power saving effect.

The DRX parameters may include: a long DRX cycle (DRX long cycle) for controlling a length of the DRX long cycle; an on duration timer for controlling the shortest time for the UE to monitor the control PDCCH channel in the DRX period; a DRX inactivity timer for controlling extension of an active period in a DRX state; a long DRX start offset (DRX long cycle start position offset) for controlling when the DRX long cycle starts; a short DRX cycle (DRX short cycle) for controlling a length of the DRX short cycle; a DRX short cycle timer (DRX short cycle timer) for controlling a lifetime of the DRX short cycle; a DRX retransmission timer (DRX retransmission timer) for ensuring that the UE can normally receive downlink retransmission data in the DRX state. Those skilled in the art will appreciate that "downlink" refers to a direction from the base station to the UE, and will not be described in detail below.

Wherein, DRX short cycle parameter and DRX short cycle timer parameter are optional parameters. If the UE does not monitor the PDCCH packet of the UE within the time period of the DRX Short CycleTimer, the UE enters into a Long DRX Cycle.

In the DRX control method according to the embodiment of the present invention, the DRX parameters can be understood by referring to the technical content of the DRX parameters in the prior art, which is not described herein again.

In the DRX control method according to the embodiment of the present invention, the DRX active period can be obtained by using the DRX parameter, and specifically, the manner of counting the DRX active period according to the DRX parameter can be understood by referring to related contents in the prior art, which is not described herein again.

Optionally, the DRX control method according to the embodiment of the present invention may further include:

and when the data volume information is determined to be higher than a corresponding second preset threshold, sending second control information to the UE, wherein the second control information is used for indicating the UE to exit the DRX state.

Wherein, the base station can carry the second control information through the RRC message.

Optionally, the manner in which the second control information indicates the UE to exit the DRX state may include:

and a release field of the RRC message carries second control information and indicates the UE to exit the DRX state.

Or, the second control information may further include an indication bit, and when the RRC message carries the indication bit, the UE is indicated to enter the DRX state.

The message carrying the second control information may be an existing message or an added message, which is not limited in the embodiment of the present invention.

Therefore, the DRX control method of the embodiment of the invention realizes the control of the DRX through the data volume information of the data transmitted by the user terminal, thereby balancing the data transmission performance and the power saving performance of the UE.

Moreover, the first preset threshold may be less than or equal to the second preset threshold, and when the first preset threshold is less than the second preset threshold, the UE may be prevented from repeatedly oscillating between entering the DRX state and exiting the DRX state.

Exemplarily, as shown in fig. 2, an embodiment of the present invention provides a DRX control method, including:

21. a base station (e.g., eNodeB) acquires data volume information of UE transmission data.

22. And when the data volume information is determined to be lower than a first preset threshold, the base station sends first control information to the UE, wherein the first control information is used for indicating the UE to enter a Discontinuous Reception (DRX) state.

23. The UE receives first control information sent by a base station, and enters a DRX state according to the first control information.

24. The base station acquires data volume information of UE transmission data.

25. And when the data volume information is determined to be higher than a second preset threshold, the base station sends second control information to the UE, wherein the second control information is used for indicating the UE to exit the Discontinuous Reception (DRX) state.

26. And the UE receives second control information sent by the base station, and exits the DRX state according to the second control information.

Specifically, in step 21, the data amount information of the UE transmission data may be acquired in the following three ways:

the method comprises the steps of obtaining the data sending rate of the UE or the data receiving rate of the UE in a time period, or obtaining the data sending rate of the UE or the data receiving rate of the UE, wherein the data volume information is the instantaneous data sending rate of the UE or the instantaneous data receiving rate of the UE.

At this time, the first preset threshold is a first speed value, the second preset threshold is a second speed value, and the first speed value is smaller than or equal to the second speed value.

The time period may be a preset time period, and may be adjusted according to needs.

Alternatively, the rate of data transmission refers to the amount of data transmission per unit time, which may be in units of bps (bits per second), or kbps (kilobits per second), or Mbps (megabits per second).

For example, the rate at which the UE transmits data on a PUSCH (Physical Uplink Shared CHannel) or the rate at which the UE receives data on a PDSCH (Physical Downlink Shared CHannel) may be obtained.

When the data transmission rate of the UE is lower than the first rate value, the data transmission rate indicates that the data transmission amount of the corresponding UE is small; when the rate of the UE data transmission is higher than the second rate value, it indicates that the amount of data of the corresponding UE data transmission is large.

Therefore, when the data transmission rate of the UE is lower than the first rate value, the UE can be controlled to enter the DRX state, the power saving performance of the UE is ensured, and when the data transmission rate of the UE is higher than the second rate value, the UE can be controlled to exit the DRX state, and the data transmission performance of the UE is ensured.

Or,

obtaining the ratio of the time for sending data by the UE to the time period in a time period, or the ratio of the time for receiving data by the UE to the time period in a time period, or the ratio of the time for sending data by the UE to receive data by the UE to the time period in a time period; the data volume information is the proportion of the time for sending data by the UE to the time period, or the proportion of the time for receiving data by the UE to the time period, or the proportion of the time for sending data by the UE to the time period.

At this time, the first preset threshold is a first time proportion value, the second preset threshold is a second time proportion value, and the first time proportion value is smaller than or equal to the second time proportion value.

Or acquiring the proportion of the number of subframes of UE sending data to the total number of subframes of the time period in a time period, or the proportion of the number of subframes of UE receiving data to the total number of subframes of the time period in a time period, or the proportion of the number of subframes of UE sending data and receiving data to the total number of subframes of the time period in a time period; the data volume information is the proportion of the number of subframes for transmitting data by the UE to the total number of subframes in the time period, or the proportion of the number of subframes for receiving data by the UE to the total number of subframes in the time period, or the proportion of the number of subframes for transmitting data by the UE and receiving data to the total number of subframes in the time period.

At this time, the first preset threshold is a first subframe proportion value, the second preset threshold is a second subframe proportion value, and the first subframe proportion value is smaller than or equal to the second subframe proportion value.

Therefore, when the ratio of the time for the UE to send data to the time period in a time period is lower than the first time ratio value, or the ratio of the time for the UE to receive data to the time period in a time period is lower than the first time ratio value, or the ratio of the time for the UE to send data to receive data to the time period in a time period is lower than the first time ratio value, it indicates that the data amount corresponding to the UE data transmission is small, and the UE can be controlled to enter a DRX state, so that the electricity saving performance of the UE is ensured.

Therefore, when the ratio of the time for the UE to send data to the time period in a time period is higher than the second time ratio, or the ratio of the time for the UE to receive data to the time period in a time period is higher than the second time ratio, or the ratio of the time for the UE to send data to the time period to receive data to the time period in a time period is higher than the second time ratio, it indicates that the data amount corresponding to the UE data transmission is large, and the UE can be controlled to exit the DRX state, thereby ensuring the data transmission performance of the UE.

It can be seen that when the ratio of the number of subframes during which the UE transmits data to the total number of subframes during a time period is lower than the first subframe ratio, or the ratio of the number of subframes during which the UE receives data to the total number of subframes during the time period is lower than the first subframe ratio, or the ratio of the number of subframes during which the UE transmits data to the number of subframes during a time period to the total number of subframes during the time period is lower than the first subframe ratio, it indicates that the data amount corresponding to the UE data transmission is small, and the UE can be controlled to enter the DRX state, thereby ensuring the power saving performance of the UE.

As can be seen, when the ratio of the number of subframes during which the UE transmits data to the total number of subframes in the time period is higher than the second subframe ratio value, or the ratio of the number of subframes during which the UE receives data to the total number of subframes in the time period is higher than the second subframe ratio value, or the ratio of the number of subframes during which the UE transmits data to the number of subframes during the time period to the total number of subframes in the time period is higher than the second subframe ratio value, it indicates that the data amount corresponding to the UE data transmission is large, and the UE can be controlled to exit the DRX state, thereby ensuring the data transmission performance of the UE.

Or,

and acquiring the proportion of the duration of the active period of the DRX state to the total duration of the time period in a certain time period in the DRX state corresponding to the DRX parameter, wherein the data volume information is the proportion of the duration of the active period of the DRX state to the total duration of the time period.

At this time, the first preset threshold is a first duration proportional value, the second preset threshold is a second duration proportional value, and the first duration proportional value is less than or equal to the second duration proportional value.

That is, the eNodeB schedules and maintains the UE according to the DRX parameter and the DRX state that the UE has entered the DRX parameter configuration. Specifically, in the statistical time period, the eNodeB performs statistics on the proportion of the DRX active period in the DRX state to the statistical time period, and if the proportion is lower than a preset threshold, the eNodeB sends the DRX parameter to the UE, thereby triggering the UE to enter the DRX state corresponding to the DRX parameter.

In the DRX control method according to the embodiment of the present invention, the DRX active period can be obtained by using the DRX parameter, and specifically, the manner of counting the DRX active period according to the DRX parameter can be understood by referring to the related content in the prior art, which is not described herein again.

Therefore, when the ratio of the active period duration of the DRX state to the total duration of the time period is lower than the first duration ratio value, the data volume of the corresponding UE data transmission is small, the UE can be controlled to enter the DRX state, and the electricity saving performance of the UE is ensured; when the ratio of the active period duration of the DRX state to the total duration of the time period is higher than the second duration ratio value, the data volume corresponding to the UE data transmission is large, the UE can be controlled to exit the DRX state, and the data transmission performance of the UE is ensured.

It should be noted that, in the DRX control method according to the embodiment of the present invention, the UE may be controlled to enter the DRX state and exit the DRX state according to different factors, for example:

and controlling the UE to enter the DRX state according to the first mode, and controlling the UE to exit the DRX state according to the second mode.

Or controlling the UE to enter the DRX state according to the first mode and controlling the UE to exit the DRX state according to the third mode.

Or controlling the UE to enter the DRX state according to the mode two, and controlling the UE to exit the DRX state according to the mode one.

Or controlling the UE to enter the DRX state according to the mode two, and controlling the UE to exit the DRX state according to the mode three.

Or controlling the UE to enter the DRX state according to the mode three, and controlling the UE to exit the DRX state according to the mode one.

Or controlling the UE to enter the DRX state according to the mode three and controlling the UE to exit the DRX state according to the mode two.

The DRX control method provided by the embodiment of the invention can avoid that when the data volume of the data transmitted by the UE is large, the UE is in the DRX state, so that the sending of SRS (Sounding Reference Signal) and CQI (Channel quality indicator) is limited, and the SRS and the CQI can influence the data transmission performance of uplink data and downlink data, and can avoid that the power saving effect of the UE is poor due to the fact that the active period of DRX is greatly expanded when the data volume is large.

The first preset threshold may be less than or equal to the second preset threshold, and when the first preset threshold is less than the second preset threshold, the UE may be prevented from repeatedly oscillating between entering the DRX state and exiting the DRX state.

Specifically, the obtaining unit 31 may be specifically configured to obtain a data sending rate of the UE or a data receiving rate of the UE within a time period, or obtain an instantaneous data sending rate of the UE or an instantaneous data receiving rate of the UE, where the data amount information is a data sending rate of the UE or a data receiving rate of the UE.

The first preset threshold is a first duration proportional value, the second preset threshold is a second duration proportional value, and the first duration proportional value is smaller than or equal to the second duration proportional value.

It will be understood by those skilled in the art that the first and second sending

units

32, 41 may be implemented by one transmitter, for example, the DRX control apparatus includes one transmitter for performing the actions performed by the first and second sending

units

32, 41. Optionally, the first sending unit 32 and the second sending unit 41 may be implemented by different transmitters, for example, the DRX control apparatus includes: a first transmitter and a second transmitter for performing the actions performed by the first transmitting unit 32 and the second transmitting unit 41, respectively.

The DRX control device provided by the embodiment of the invention can avoid that when the data volume of UE transmission data is large, the UE is in the DRX state, so that the sending of SRS and CQI is limited, and the SRS and CQI can influence the data transmission performance of uplink data and downlink data, and can avoid that when the data volume is large, the active period of DRX is greatly expanded, so that the power saving effect of the UE is poor.

The DRX control apparatus and the configuration thereof provided in the embodiments of the present invention may be used to implement actions performed by a base station in the DRX control method provided in the above embodiments, and may be understood by referring to corresponding parts of the DRX control method in the above embodiments specifically, and are not described herein again.

The DRX processing equipment of the embodiment of the invention avoids that when the data volume of the UE transmission data is large, the UE is in the DRX state, so that the sending of the SRS and the CQI is limited, and the SRS and the CQI can influence the data transmission performance of the uplink data and the downlink data, and simultaneously avoids that when the data volume is large, the active period of the DRX is greatly expanded, so that the power saving effect of the UE is poor.

The DRX processing apparatus and the configuration thereof provided in the embodiments of the present invention may be used to implement actions performed by the UE in the DRX processing method provided in the above embodiments, and may be understood by referring to corresponding parts of the DRX processing method in the above embodiments specifically, and are not described herein again.

The following describes the DRX control method according to the present invention with a specific application embodiment, taking an LTE system as an example.

Embodiment 1 of the invention

In the DRX control method of the embodiment of the present invention, entering or exiting a DRX state is controlled based on a rate at which UE transmits data:

and in the counting time period, the eNodeB counts the data transmission rate of the UE, when the rate is lower than a preset threshold value, the data volume of the data transmission corresponding to the UE is small, the eNodeB sends the DRX parameter to the UE to trigger the UE to enter a DRX state, and when the rate is higher than the preset threshold value, the data volume of the data transmission corresponding to the UE is large to trigger the UE to exit the DRX state.

Of course, 2 different DRX entry and exit state thresholds may also be set to avoid the UE from oscillating repeatedly between entering and exiting the DRX state.

Therefore, when the data volume of the UE data transmission is small, the UE enters the DRX state to ensure the power saving performance of the UE, and when the data volume of the UE data transmission is large, the UE exits the DRX state to ensure the data transmission performance of the UE.

Example two of the invention

In the DRX control method of the embodiment of the invention, the entering or exiting DRX state is controlled based on the proportion of the number of subframes of UE sending data to the total number of subframes:

in the statistical time period, the eNodeB counts the number of the subframes of the data sent by the UE, calculates the ratio of the number of the subframes of the data sent by the UE to the total number of the subframes of the statistical time period, when the ratio is lower than a preset threshold value, the data volume of the data transmission corresponding to the UE is small, the eNodeB sends a DRX parameter to the UE to trigger the UE to enter a DRX state, and when the ratio is higher than the preset threshold value, the data volume of the data transmission corresponding to the UE is large, and the UE is triggered to exit the DRX state.

Third embodiment of the invention

In the DRX control method of the embodiment of the invention, the entering or exiting DRX state is controlled based on the proportion of the active period in the DRX state:

although the UE does not enter the DRX state, the eNodeB selects a set of DRX parameters for the UE, which mainly includes the following items: a long DRX cycle (DRX long cycle) for controlling a length of the DRX long cycle; an on duration timer for controlling the minimum time for the UE to monitor the control PDCCH channel in the DRX state; a DRX inactivity timer for controlling extension of an active period in the DRX state; long DRX startoffset (DRX long cycle start position offset) for controlling when the DRX long cycle starts; a short DRX cycle (DRX short cycle) for controlling a length of the DRX short cycle; a DRX short cycle timer (DRX short cycle timer) for controlling a lifetime of the DRX short cycle; a DRX retransmission timer (DRX retransmission timer) for ensuring that the UE can normally receive downlink retransmission data in the DRX state.

And the eNodeB schedules and maintains the UE according to the DRX parameters and the DRX state configured by the DRX parameters. However, the DRX parameter is not configured to the UE at this time.

Specifically, in the statistical time period, the eNodeB performs statistics on the proportion of the DRX active period in the statistical time period, and sends the DRX parameter to the UE if the proportion is lower than a preset threshold, thereby triggering the UE to enter a DRX state corresponding to the DRX parameter.

After the UE enters the DRX state corresponding to the DRX parameter, the eNodeB also counts the proportion of the DRX active period in the DRX state, and if the proportion is higher than a preset threshold value, the eNodeB triggers the UE to exit the DRX state

Inventive example four

In the DRX control method of the embodiment of the present invention, the factors considered in controlling to enter the DRX state and controlling to exit the DRX state are different:

and in the counting time period, the eNodeB counts the data transmission rate of the UE, when the rate is lower than a preset threshold value, the data transmission amount of the corresponding UE is small, and the eNodeB sends the DRX parameter to the UE to trigger the UE to enter a DRX state.

After the UE enters the DRX state, the eNodeB counts the number of the subframes of the data sent by the UE in the counting time period, calculates the proportion value of the number of the subframes of the data sent by the UE to the total number of the subframes in the counting time period, and triggers the UE to exit the DRX state when the proportion value is higher than a preset threshold value and the data volume corresponding to the data transmission of the UE is large.

Example five of the invention

and in the statistical time period, the eNodeB carries out statistics on the data transmission rate of the UE, when the rate is lower than a preset threshold, the data transmission amount of the corresponding UE is small, and the eNodeB transmits the DRX parameter to the UE to trigger the UE to enter a DRX state.

After the UE enters the DRX state, the eNodeB counts the proportion of the DRX active period in the statistical time period, and if the proportion is higher than a preset threshold value, the eNodeB sends the DRX parameter to the UE, so that the UE is triggered to exit the DRX state corresponding to the DRX parameter.
