Description

Method and device for reducing data receiving time delay
The present application claims priority from a chinese patent application filed by the chinese patent office on 26/4/2018 under application number 201810387682.4 entitled "a method for reducing data transmission latency", which is incorporated herein by reference in its entirety.
Technical Field
The present application relates to the field of mobile communications technologies, and in particular, to a method and an apparatus for reducing data reception delay.
Background
In the field of mobile communications, Discontinuous Reception (DRX) refers to a working mode of a communication device such as a User Equipment (UE) or a base station that saves power consumption of the UE, taking the UE as an example, in the DRX mode, the UE is alternately in an active state and a sleep state, and the UE turns on a receiver only in the active state to monitor and receive downlink data and signaling, and turns off the receiver to stop receiving the downlink data and the signaling when in the sleep state, so that transmission delay when the UE is in the active state is lower than transmission delay when the UE is in the sleep state.
In the current DRX scheme, a base station sends a DXR parameter to a communication device managed by the base station to configure a duration that the communication device is in a sleep state and a duration that the communication device is in an active state, and once the communication device receives the DRX parameter configured by the base station and executes DRX according to the DRX parameter, the communication device cannot actively request to extend the active state to reduce transmission delay.
Disclosure of Invention
The application provides a method and a device for reducing data receiving time delay, which are used for solving the technical problem that the conventional communication equipment cannot actively request to prolong an active state or stop executing DRX so as to reduce transmission time delay.
In a first aspect, an embodiment of the present application provides a method for reducing data reception delay, where a communication device sends a request message to a network device, where the request message is used for the network device to determine to send a first message to the communication device, so that the network device may send the first message to the communication device after receiving the request message, where the first message is used for the communication device to determine an extended activation state, and the communication device extends the activation state after receiving the first message.
By adopting the method, the communication equipment such as the UE can request the network equipment to prolong the time length in the activated state, and the activated state is prolonged after the first message sent by the network equipment is received.
In one possible design, the communication device may send a request message to the network device before determining that the duration timer and/or the inactivity timer maintained by the communication device is timed out, so as to avoid that the communication device enters a sleep state due to the timed-out of the duration timer and the inactivity timer, and increase the transmission delay; in implementation, the communication device may send the request message to the network device when determining that the self-maintained inactivity timer is in a timed state or not, and determining that the self-maintained persistence timer is not overtime; the communication device may also send a request message to the network device upon determining that the self-maintained keep-alive timer is in or out of the timed state and that the self-maintained inactivity timer is not expired.
In one possible design, the communication device may send a request message to the network device after determining to enter a low latency scenario and/or use a low latency service, so as to avoid an increase in power consumption caused by the communication device extending an active state when not in the low latency scenario or not using the low latency service.
In one possible design, the communication device may send a scheduling request SR to the network device, and after receiving the scheduling request, the network device may send a PDCCH scheduling signaling to the communication device, so as to restart an inactive state timer of the communication device, and after receiving the PDCCH scheduling signaling sent by the network device, the communication device restarts the inactive state timer to prolong an active state. In implementation, after sending the PDCCH scheduling signaling to the communication device, the network device may restart the non-active state timer of the communication device that is maintained by the network device, and consider that the communication device is in an active state before the non-active state timer times out, so that the network device may immediately perform downlink transmission to the communication device after receiving downlink data that needs to be sent to the communication device.
In one possible design, if the communication device performs DRX according to the first DRX parameter before sending the request message, the communication device may carry second DRX parameter information in the request message, which is used to request the network device to configure the second DRX parameter information for the communication device.
In an implementation, the network device may carry, in the first message, information indicating that it is agreed to configure the second DRX parameter for the communication device, so that the communication device may perform DRX according to the second DRX parameter information after receiving the first message, where the second DRX parameter information may include one of the following information: information indicating that the communication apparatus does not perform DRX, indicating that the communication apparatus does not enter a sleep state within a long DRX cycle, indicating that the length of the long DRX cycle is set to 0: information indicating a length of the long DRX cycle, the length of the long DRX cycle being smaller than the length of the long DRX cycle indicated by the first DRX parameter information; information indicating a value of an inactivity timer, the value of the inactivity timer being greater than the value of the inactivity timer indicated by the first DRX parameter information; information indicating a value of an on duration timer, the value of the on duration timer being greater than the value of the on duration timer indicated by the first DRX parameter information; information indicating a value of a short cycle timer, the value of the short cycle timer being smaller than the value of the short cycle timer indicated by the first DRX parameter information. By adopting the above mode, after the communication equipment receives the first message, the DRX can not be executed according to the first DRX parameter information any more, and the DRX can be executed according to the second DRX parameter information, so that the extension of the active state can be realized.
In addition, in an implementation, the network device may carry third DRX parameter information in the first message, so that the communication device may perform DRX according to the third DRX parameter information after receiving the first message, where the third DRX parameter information may include one of the following information: information indicating that the communication apparatus does not perform DRX, indicating that the communication apparatus does not enter a sleep state within a long DRX cycle, indicating that the length of the long DRX cycle is set to 0: information indicating a length of the long DRX cycle, the length of the long DRX cycle being smaller than the length of the long DRX cycle indicated by the first DRX parameter information; information indicating a value of an inactivity timer, the value of the inactivity timer being greater than the value of the inactivity timer indicated by the first DRX parameter information; information indicating a value of an on duration timer, the value of the on duration timer being greater than the value of the on duration timer indicated by the first DRX parameter information; information indicating a value of a short cycle timer, the value of the short cycle timer being smaller than the value of the short cycle timer indicated by the first DRX parameter information. By adopting the above mode, after receiving the first message, the communication device does not execute DRX according to the first DRX parameter information any more, and executes DRX according to the third DRX parameter information, thereby realizing the extension of the active state.
In one possible design, a request message sent by a communication device to a network device may carry information indicating that DRX discontinuous reception capability of the communication device is not supported by DRX, the network device may send, after receiving the request message, a first message specifically used for instructing the communication device not to perform DRX to the communication device, and the communication device may not enter a sleep state from an active state after receiving the first message. In implementation, the request message sent by the communication device to the network device may be a registration request message for implementing re-registration of the communication device, and the communication device informs the network device of information that the communication device does not support DRX through the registration request. In implementation, the request message may include a DRX command medium access control element, where the corresponding bit of the element is 0.
In a possible design, before the communication device sends the request message to the network device, it may be further determined that a time interval from the previous sending of the first registration request by the communication device reaches a preset time duration, for example, the preset time duration may be 24 hours, so as to prevent the communication device from performing the registration process frequently.

The following describes a DRX manner performed by the communication device 101, taking the communication device 101 as an example: when performing DRX, the UE needs to configure a value of an on duration timer (on duration timer) maintained by the UE according to DRX parameter information sent by the network side device 102 (for example, the value of the on duration timer in the DRX parameter information is 100, and the UE may configure the on duration timer according to the DRX parameter information and make it execute a maximum timing of 100 milliseconds) and a value of an inactive state timer (DRX inactivity timer), where the values of the on duration timer and the inactive state timer may be indicated by a slot (slot) or a symbol (symbol) number; the value of the duration timer may be used to indicate the shortest duration for the communication device to remain in the active state after entering the active state, and the value of the inactivity timer may be used to indicate the duration for the communication device to remain in the active state after receiving a scheduling signaling of a Physical Downlink Control Channel (PDCCH) each time; when the UE performs DRX according to the DRX parameter information, the schematic diagram of the DRX cycle is as shown in fig. 5, when performing DRX, the UE turns on the receiver only at necessary time to enter an active state to receive downlink data and signaling, and turns off the receiver at other time to enter a sleep state to stop receiving downlink data and signaling to save power consumption of the UE. DRX is divided into idle DRX and connected DRX. C-DRX (C-DRX, namely connected DRX, is DRX in RRC connected state) refers to DRX characteristics of UE in RRC connected state, the C-DRX is realized by monitoring PDCCH, the UE (although in connected state) can enter a sleep state periodically according to the DRX, and meanwhile, the base station considers that the UE is in the sleep state; the base station does not schedule data for the UE in the sleep state, and the UE in the sleep state does not receive the PDCCH; (including voice traffic, the UE will also perform DRX); the base station only sends a PDCCH to the UE for scheduling when the UE is in an activated state (including the time indicated by the on Duration Timer, which is defined as a wake-up window), and the UE also receives the PDCCH sent by the base station in the wake-up window; in the Long DRX cycle window, except the on Duration Timer, the UE is in a sleep state, and the base station does not send the PDCCH to the UE for scheduling; in the DRX long cycle, except for the time indicated by the on duration tier, the UE may be in a sleep state, and if the UE transmits an SR in the long cycle, the UE may be in an awake state. When the UE enters the activation state each time, starting the timing of a continuous timer, wherein the UE is kept in the activation state before the timing of the continuous timer is overtime (the overtime means that the counting of the timer reaches a value configured for the UE), so that the UE can receive downlink data and signaling; when the continuous timer times out, the UE determines whether the inactive state timer is in a timing state, if the inactive state timer is not in the timing state (not starting timing or timed out), the UE may end the active state and enter a sleep state of DRX, and if the inactive state timer is still in the timing state, the UE still needs to remain in the active state until the timing of the inactive state timer times out, where the inactive state timer works according to a principle that the UE in the active state starts the timing of the inactive state timer each time it receives a PDCCH scheduling signaling (or restarts the timing of the inactive state timer, that is, the inactive state timer in the timing state is restarted).
For example, the UE may configure the persistence timer according to the number of timeslots or the number of symbols configured by the network side device 102, for example, the number of timeslots configured by the network device 102 for the persistence timer of the UE is 10, and assuming that the timeslot length of the partial Bandwidth (BWP) currently activated by the UE 102 is 1 millisecond (ms), the duration of the persistence timer, which is actually required to be executed after the timeout of the timing, is 1 ms; if the UE101 starts the duration timer, and the duration timer expires after counting for 10ms, it indicates that the UE has monitored 10 timeslots of the currently activated BWP; for another example, the number of symbols configured by the network device 102 for the duration timer of the UE is 10, the slot length of the BWP currently activated by the UE is 1ms, if the slot length of the BWP is seven times of the symbol length, that is, the symbol length of the BWP is 0.143ms, the actual time duration from the time counting of the duration timer to the time counting timeout is 1.43ms, and if the duration timer expires after performing the time counting of 1.43ms, it indicates that the UE has monitored 10 symbols. In implementation, the configuration of the inactivity timer may refer to the above-exemplified configuration of the persistence timer.
If the communication device 101 is a UE, a method for reducing data reception delay according to an embodiment of the present application may include the steps shown in fig. 6:
step S101: the UE sends a request message to the network equipment 102, wherein the request message is used for the network equipment 102 to determine to send a first message to the UE, and the first message is used for the UE to determine to prolong the time length of the UE in an active state when the DRX is received discontinuously;
step S102: network device 102 receives a request message sent by a UE;
step S103: network device 102 sends a first message to the UE:
step S104: and after the UE receives the first message, prolonging the time length of the UE in the activated state.
By adopting the method, the UE can actively send the request message to request to prolong the activation state during the DRX, and after receiving the first message sent by the network equipment 102, the UE can prolong the duration of the activation state with lower transmission delay, thereby reducing the transmission delay of the UE.
In the implementation of step S104, the extension of the active state of the UE may be implemented by starting or restarting (resetting) the timing of an inactive state timer of the UE, specifically, if the current inactive state timer of the UE is in a timing state, the UE may reset the inactive state timer, and restart the timing of the inactive state timer; if the current inactivity timer of the UE is not in the working state, the UE may start timing by the inactivity timer.
According to the above scheme, the transmission delay of the UE can be reduced but the power consumption of the UE can be increased, and it can be determined that the UE enters a low-delay scenario and/or that the UE uses a low-delay service before the UE performs the steps shown in S101, so that the increase of the power consumption of the UE caused by the reduction of the data reception delay time length by the method for reducing the data reception delay described in the present application performed under the condition that the UE does not enter the low-delay scenario and does not use the low-delay service can be avoided. It should be noted that the low latency scenario herein includes, but is not limited to, application scenarios where the UE enters into a red packet, snatchs a train ticket, plays an online game, etc., and in this scenario, the UE needs to be in a low transmission latency state for a long time; low latency services include, but are not limited to, calls used by UEs, Virtual Reality (VR), Augmented Reality (AR), or ultra-reliable low latency Communication (URLLC).
It should be understood that the UE in step S101 sends a request message to the network device 102, including but not limited to one or more of the following: the UE sends a request message to the network device 102 and the request message is successfully sent; the UE prepares to send a request message to the network device 102, the request message not yet being successfully sent; the UE has triggered the sending of the request message, which has not been successfully sent.
For example, before step S101, the UE may receive DRX parameter information configured for the UE by the network device 102, and perform DRX according to the DRX parameter information. Specifically, the network device 102 may send first DRX parameter information to the UE, where the UE configures at least one of the following according to the first DRX parameter information: a long DRX cycle (long DRX cycle), an inactive state Timer, a short cycle Timer (DRX short cycle Timer), a hybrid automatic repeat request (HARQ) loop time (RTT) Timer (HARQ RTT Timer), a retransmission Timer (DRX retransmission Timer), and an On Duration Timer.
In implementation, the UE may further perform the step shown in S101 before determining that the persistent timer and/or the inactive state timer maintained by the UE is expired, so as to avoid that the UE enters the sleep state due to the expiration of the persistent timer and the inactive state timer before the active state is extended according to the methods shown in steps S101 to S104.
Specifically, before step S101, the UE may determine that a persistent timer maintained by itself has not expired, and/or determine that an inactive state timer maintained by itself has not expired; or, the UE may further execute the step shown in S101 when determining that the persistent timer maintained by the UE is in the time keeping state or not in the time keeping state and determining that the inactivity timer maintained by the UE is not overtime; alternatively, the UE may further execute the step shown in S101 when the inactivity timer maintained by the UE is in the time counting state or not in the time counting state, and it is determined that the continuous timer maintained by the UE is not timed out.
It should be understood that the embodiments of the present application do not limit the UE to perform the step shown in S101 after determining that the persistent timer and/or the inactive state timer maintained by the UE expires, for example, the UE may perform the step shown in S101 to reduce the transmission delay even if the UE has determined that the persistent timer and the inactive state timer expire. For example, after the persistence timer expires, in a case that it is determined that the duration that the persistence timer has expired is less than N times of the timing duration represented by the value configured for the persistence timer by the UE, the UE may perform the step shown in S101, where N may be 3, 2, or 1.5; after the inactivity timer, the UE may also execute the step S101 when determining that the time length that the inactivity timer has timed out is less than N times of the timing time length represented by the value configured for the inactivity timer by the UE, where N may be 3, 2, or 1.5. In the above manner, even if the duration timer and/or the inactivity timer expires, the UE may still be in the active state for a period of time after performing the steps shown in S101 to S104, so as to reduce the transmission delay.
For example, in the implementation of step S101, when sending the request message to the network device 102, the UE may generate uplink data through a higher layer (e.g., through an application layer), and trigger a modem (modem) module of the UE to send the request message based on the generated uplink data; alternatively, the UE may trigger the modem module to send the request message through an Application Processor (AP) module; alternatively, the user equipment may directly transmit the request message through the modem module. In implementation, the UE may also trigger the SR to transmit by transmitting an IP (internet protocol) packet to the designated 1 or more servers.
In the implementation of step S101, the request message sent by the UE to the network device 102 is a Scheduling Request (SR), the SR may be used to request an uplink resource, where the uplink resource may be used for the UE to send uplink data, after receiving the SR, the network device 102 may send a PDCCH scheduling signaling to the UE, where the PDCCH scheduling signaling is used to indicate the uplink resource to the UE, and after receiving the PDCCH scheduling signaling, the UE may restart the timing of the inactive status timer, so as to extend the timing duration of the inactive status timer and keep the active status before the timing of the active status timer expires.
As shown in fig. 7, a method for reducing data reception delay according to an embodiment of the present application may include the following steps:
step 701: the network device 102 sends first DRX information to the UE; the first DRX information is used for configuring the UE to execute DRX;
step 702: after receiving the first DRX parameter information sent by the network device 102, the UE executes DRX according to the first DRX parameter information;
step 703: the UE determines to enter a low-delay scene and/or determines to use a low-delay service; for example, after receiving downlink red packet data, the UE may determine to enter a low-delay red packet robbing scenario; the low-delay service may be a call service, etc.;
step 704: the UE determines that the timing of a self-maintained continuous timer and/or an inactive state timer is not overtime;
step 705: the UE sends an SR to the network device 102;
step 706: after receiving the SR sent by the UE, the network device 102 sends a PDCCH scheduling signaling to the UE, and starts or restarts the inactive state timer maintained by the network device 102, and before the time of the inactive state timer maintained by the network device 102 expires, the network device 102 determines that the UE is in an active state;
step 707: after receiving the PDCCH scheduling signaling sent by the network device 102, the UE starts or restarts the timing of the inactive state timer, and keeps the active state before the timing of the inactive state timer is over time, and then ends the process.
By adopting the method, the UE can actively request the network device 102 to send the PDCCH scheduling signaling to the UE to indicate uplink resources by sending the SR to the network device 102, the UE can start (or restart) the timing of its own non-active state timer to extend the active state after receiving the PDCCH scheduling signaling, so as to avoid that the UE enters the DRX sleep state and cannot receive downlink data in a low-delay scenario and/or cannot use a low-delay service, and the network device 102 can also start (or restart) the timing of the non-active state timer after sending the PDCCH scheduling signaling to the UE.
In the implementation of step S101, the UE may further carry second DRX parameter information in the request message sent to the network device 102, where the second DRX parameter information is different from the first DRX parameter information previously received by the UE, so that, in step S103, the network device 102 may send a first message to the UE to indicate that the network device 102 agrees to configure the second DRX parameter information for the UE, for example, the first message may carry a specific bit, and the UE may perform DRX according to the second DRX parameter information after receiving the first message carrying the specific bit; alternatively, the network device 102 may also carry the second DRX parameter information in the first message to indicate that the UE is agreeable to configure the second DRX parameter information; in an implementation, the first message sent by the network device 102 to the UE may be a Radio Resource Control (RRC) message;
wherein the second DRX parameter information may indicate that the UE is no longer in the sleep state and thus the UE may remain in the active state without entering the sleep state, for example, the second DRX parameter information may include at least one of: information for indicating that the UE does not use the DRX mechanism, information for indicating that the UE does not enter a sleep mode within a long DRX cycle, and information for indicating that the long DRX cycle is set to 0; wherein the information indicating that the UE does not use the DRX mechanism may include time information indicating that the UE does not use the DRX mechanism, for example, information indicating that the UE does not use the DRX mechanism, including information indicating that the UE does not use the DRX mechanism within 60 minutes;
the second DRX parameter information may also instruct the UE to perform a shorter long DRX cycle (long DRX cycle), for example, the second DRX parameter information carries information for indicating the length of the long DRX cycle, which is smaller than the length of the long DRX cycle indicated by the first DRX parameter information;
the second DRX parameter information may also instruct the UE to perform a longer short DRX cycle (short DRX cycle), for example, the second DRX parameter information carries information for indicating the length of the short DRX cycle, which is greater than the length of the short DRX cycle indicated by the first DRX parameter information;
in addition, the second DRX parameter information may also instruct the UE to increase a maximum timing of the on-duration timer and/or to increase a maximum timing of the inactive state timer. For example, the second DRX parameter information carries information indicating a value of an on duration timer, which is greater than the value of the on duration timer indicated by the first DRX parameter information; the second DRX parameter information may also carry information indicating a value of an inactivity timer, which is greater than the value of the inactivity timer indicated by the first DRX parameter information.
In another implementation, after the UE sends the second DRX parameter information to the network device 102, if the network device 102 indicates that the UE configures the second DRX parameter information differently, the network device 102 may further configure a new DRX parameter information for the UE and instruct the UE to perform DRX according to the new DRX parameter information through the first message, so as to extend the active state of the UE, where the new DRX parameter information configured for the UE by the network device 102 is different from the second DRX parameter information. Specifically, in S103, the network device 102 may carry the third DRX parameter information in the first message, so that the UE performs DRX according to the third DRX parameter information after receiving the first message. In an implementation, the first message sent by the network device 102 to the UE may be an RRC message.
Wherein the third DRX parameter information may indicate that the UE is no longer in the sleep state and thus the UE may remain in the active state without entering the sleep state, for example, the third DRX parameter information may include at least one of: information for indicating that the UE does not use the DRX mechanism, information for indicating that the UE does not enter a sleep mode within a long DRX cycle, and information for indicating that the long DRX cycle is set to 0; wherein the information indicating that the UE does not use the DRX mechanism may include time information indicating that the UE does not use the DRX mechanism;
the third DRX parameter information may also instruct the UE to perform a shorter long DRX cycle, for example, the third DRX parameter information carries information for indicating the length of the long DRX cycle, which is smaller than the length of the long DRX cycle indicated by the first DRX parameter information;
the third DRX parameter information may also instruct the UE to perform a longer short DRX cycle, for example, the third DRX parameter information carries information for indicating the length of the short DRX cycle, and the length of the short DRX cycle is greater than the length of the short DRX cycle indicated by the first DRX parameter information;
in addition, the third DRX parameter information may also instruct the UE to increase a maximum timing of the on-duration timer and/or to increase a maximum timing of the inactive state timer. For example, the third DRX parameter information carries information indicating a value of an on duration timer, which is greater than the value of the on duration timer indicated by the first DRX parameter information; the third DRX parameter information may also carry information indicating a value of an inactivity timer, which is greater than the value of the inactivity timer indicated by the first DRX parameter information.
As shown in fig. 8, a method for reducing data reception delay according to an embodiment of the present application may include the following steps:
step 801: the network device 102 sends first DRX information to the UE; the first DRX information is used for configuring the UE to execute DRX;
step 802: after receiving the first DRX parameter information, the UE executes DRX according to the first DRX parameter information;
step 803: the UE determines to enter a low-delay scene and/or determines to use a low-delay service; for example, after receiving downlink red packet data, the UE may determine to enter a low-delay red packet robbing scenario; the low-delay service may be a call service, etc.;
step 804: the UE determines that the timing of a self-maintained continuous timer and/or an inactive state timer is not overtime;
step 805: the UE sends a request message to the network equipment 102, wherein the request message carries second DRX parameter information;
step 806: after receiving the request message sent by the UE, the network device 102 sends a first message to the UE; in an implementation, the first message may be used to indicate that the network device 102 agrees to configure the second DRX parameter information for the UE, or the first message may carry third DRX parameter information configured for the UE by the network device 102;
step 807: after receiving the first message sent by the network device 102, the UE executes DRX according to the second DRX parameter information; or the UE executes DRX according to the third DRX parameter information carried in the first message.
By adopting the method, the UE can request the network equipment 102 to configure the second DRX parameter information for the period so as to reduce the time length of the data receiving time delay, the network equipment 102 can send the first message indicating the agreement to the UE, and can also carry the third DRX parameter information configured for the UE in the first message, and the UE can execute the DRX according to the second DRX parameter information or the third DRX parameter information so as to realize the extension of the activation state.
In another implementation manner of step S101, the UE may further notify the network device 102 that the DRX capability of the UE is not DRX-supported through a request message sent to the network device 102, for example, the UE sends a request message indicating that the DRX capability of the UE is not DRX-supported to the network device 102, so that the UE may no longer enter the sleep state from the active state according to a first message sent by the network device 102, the first message may be used to instruct the UE not to perform DRX, and meanwhile, the network device 101 may determine that the UE does not enter the sleep state after sending the first message to the UE, so that the network device 102 may perform downlink transmission to the UE after receiving downlink data that needs to be sent to the UE, so that it is no longer necessary to wait for the UE to enter the active state from the sleep state, and transmission delay is reduced.
Specifically, the request message sent by the UE to the network device 102 may be a registration request for accessing the network by the UE, where the registration request may carry information indicating that the DRX capability of the UE does not support DRX; the first message sent by the network device 102 may specifically be used to instruct the UE not to configure at least one of the following: a long DRX cycle, an on duration timer, an inactive state timer, a short cycle timer, a hybrid automatic repeat request loop back time timer, or a retransmission timer. In an implementation, in the registration request sent by the network device 102, a bit position corresponding to a DRX command media access control element (DRX command MAC control element) may be set to 0 to indicate that the DRX capability of the UE does not support DRX.
For example, before the UE sends the above registration request to the network device 102, it may further determine that a time interval from a sending time of a first registration request has reached a preset duration, where the first registration request is a registration request sent by the UE before, and a DRX capability of the UE indicated by the first registration request is different from a DRX capability indicated by the registration request sent by the UE to the network device 102 in step S101, for example, the first registration request may carry information indicating that the UE supports DRX. For example, the preset duration may be set to 24 hours, or 60 minutes, or ten minutes to avoid frequently modifying the DRX capability of the UE.
As shown in fig. 9, a method for reducing data reception delay according to an embodiment of the present application may include the following steps:
step 901: the UE sends a first registration request to the network equipment 102, wherein the first registration request carries information indicating that the UE supports DRX; in implementations, the UE may determine and record a time at which to send the first registration request;
step 902: after the registration of the UE is completed, the network device 102 sends first DRX information to the UE; the first DRX information is used for configuring the UE to execute DRX;
step 903: after receiving the first DRX parameter information, the UE executes DRX according to the first DRX parameter information;
step 904: the UE determines to enter a low-delay scene and/or determines to use a low-delay service; for example, after receiving downlink red packet data, the UE may determine to enter a low-delay red packet robbing scenario; the low-delay service may be a call service, etc.;
step 905: the UE determines that the timing of a self-maintained continuous timer and/or an inactive state timer is not overtime;
step 906: the UE sends a registration request to the network equipment 102, wherein the registration request carries information indicating that the UE does not support DRX;
step 907: after receiving a registration request sent by the UE, the network device 102 sends a first message to the UE, the first message being used for indicating that the UE does not execute DRX;
step 908: after receiving the first message sent by the network device 102, the UE does not enter the sleep state any more.
By adopting the method, the UE can request the network equipment 102 to perform the UE re-registration, and the UE is indicated not to execute the DRX by re-registering another network equipment 102, so that the UE does not enter the sleep state from the active state any more, and the extension of the active state is realized.
In another method for reducing data reception delay provided in this embodiment, a UE performing DRX according to first discontinuous reception DRX parameter information configured by a network device sends a scheduling request SR to the network device 102 multiple times within a preset first duration to request the network device 102 to configure an uplink resource for the UE, where a time interval between any two consecutive times of sending the SRs is determined according to a value of an inactive state timer, the network device sends a PDCCH scheduling signaling to the UE after receiving the SR each time, the UE starts or restarts an inactive state timer maintained by the UE after receiving the PDCCH scheduling signaling each time, and the UE is kept in an active state before the time of the inactive state timer expires; in an implementation, the network device 102 may also start or restart the timing of the inactivity timer maintained by itself after each PDCCH scheduling signaling is sent, and determine that the UE is in the active state before the timing of the inactivity timer is expired. For example, the first duration may be a preset duration, for example, 1000ms, 60 minutes, and the like, and may be determined according to a low-latency scenario entered by the communication device or a latency requirement of the executed low-latency service.
In implementation, after determining to enter a low latency scenario and/or use a low latency service, the communication device may send a scheduling request SR to the network device 102 multiple times within a preset first duration, so as to save power consumption of the communication device.
In an implementation, the time interval may be determined according to a maximum timing of the inactivity timer, and the time interval may be different between any two transmissions of the SR. For example, if the maximum count of the inactivity timer is 100 (the unit may be s seconds, ms milliseconds, or subframe, or slot, or symbol), we take ms as an example, such as: the UE may send the SR once within the first time duration after a time of about 100ms, for example, the UE may send one SR after a time of 130 (i.e., 100+30) ms, and send the next SR after a time of 70 (i.e., 100-30) ms; for another example: the UE may transmit one SR after 120 (i.e., 100+20) ms, or may transmit one SR after 80 (i.e., 100-20) ms.
In another embodiment, the time interval may be smaller than the maximum timing of the inactivity timer, for example, the maximum timing of the inactivity timer is 100ms, and the UE may transmit an SR in a time interval smaller than 100ms, for example, the time interval is 80 or 90ms, so that the UE may not enter the sleep state, or may be in the sleep state for a shorter time.
In another embodiment, the time interval may also be greater than or equal to the maximum count of the inactivity timer. For example, the time interval may be greater than a maximum timing of an inactivity timer maintained by the communication device and less than N times the maximum timing, where N is 3, 2, or 1.5.
For example, if the maximum timing of the inactivity timer is 100ms, the UE may wait for a time interval greater than 100ms and less than 300ms to send one SR each time; alternatively, the UE waits for a time interval greater than 100ms and less than 150ms at a time to transmit one SR. Therefore, the UE may stay awake for a period of time within the DRX long cycle (excluding the time indicated by the on duration timer) to reduce the reception delay of the UE, otherwise, the UE stays in the sleep state for the DRX long cycle (excluding the time indicated by the on duration timer).
In a possible implementation manner, the time intervals between any two consecutive transmissions of the SR by the communication device are all preset durations, so that the communication device can transmit the scheduling request SR to the network device every other preset duration within the first duration, for example, if the maximum timing of the inactive state timer is 100ms, the preset duration can be 80ms, so that the communication device can transmit one SR every 80ms within the first duration.
Illustratively, the embodiment of the present application further provides a method for extending a wake-up state, which is applied to a user equipment, and includes:
the user equipment judges whether the on duration timer and/or the inactivity timer activity timer is overtime or before or after the overtime;
