Description

Discontinuous reception DRX (discontinuous reception) adjusting method and device
Technical Field
The present invention relates to the field of wireless communications technologies, and in particular, to a method and an apparatus for adjusting Discontinuous Reception (DRX).
Background
At present, the most concerned of NB-IoT (narrowband Internet of things) and LTE is the power saving and low cost of the terminal, DRX (discontinuous reception), that is, a mechanism for the terminal to sleep periodically, which is designed for power saving, and comprises a connection state DRX (C-DRX) and an idle state DRX (idle state DRX) I-DRX; wherein, the I-DRX can be further divided into sDRX (short period DRX) and eDRX (long period DRX). The sDRX is the existing DRX of the LTE, the maximum sleep time is 2.56 seconds, the eDRX is the enhancement of the LTE in the R13 version aiming at the long standby requirement of the application of the Internet of things, and the sleep time is 2.56 seconds to 2.91 hours.
The configuration method of the sDRX comprises the following steps: the UE leaves a factory and is provided with an sDRX period, a cell where the UE resides also broadcasts the sDRX period, and the UE selects the shortest one from the two as the sleep period of the UE. And paging according to the sDRX when the eNB pages.
The eDRX configuration method comprises the following steps: and the UE reports the expected eDRX period to the MME, the MME feeds back a suggested eDRX period, and the UE adopts the suggested eDRX period as the sleep period of the UE. The MME also informs the serving base station of the UE of the eDRX.
Generally, for saving power, the terminal generally uses eDRX with a longer sleep cycle. Thus, as described above, both the MME and eNB may know the eDRX cycle of the UE.
However, the existing protocol sdrc is configured by the base station, eDRX is specified by the MME after the UE coordinates with the MME, and in general, DRX is specified by the network side. The UE cannot flexibly adjust the DRX sleep cycle, such as lengthening or shortening the cycle, so that the current traffic characteristics of the UE may not match the DRX cycle.
To solve this problem, in the prior art, there is a PPI (power preference index) indication, when the UE enters a connected state, the PPI indication is sent to the base station, and the base station adjusts the DRX cycle of the UE to be long (the PPI indication does not carry an expected value, and the base station autonomously determines how to adjust, and the base station adjusts all terminals together in a broadcast manner). However, this solution still has two disadvantages: 1. the DRX period can be adjusted only by entering a connected state; 2. the cycle can only be adjusted to be long in one direction, and cannot be adjusted to be short.

Detailed Description
In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.
Aiming at the problem that the scheme for adjusting the DRX period by the terminal in the prior art is inconvenient and imperfect, the invention provides a plurality of solutions, which are as follows:
example one
As shown in fig. 1, a method for adjusting DRX in discontinuous reception according to an embodiment of the present invention is applicable to a terminal, and includes:
step 11: sending request information for adjusting a DRX period to a base station; the request information may request to adjust the DRX cycle length, or invariance;
step 12: receiving indication information fed back by the base station according to the request information;
step 13: and when the indication information indicates that the DRX period is permitted to be adjusted, adjusting the local DRX period according to the indication information.
The discontinuous reception DRX adjustment method provided by the embodiment of the invention sends the request information for adjusting the DRX period to the base station, and the request information can request to adjust the DRX period to be long, short or unchanged; then receiving indication information fed back by the base station according to the request information, and adjusting the local DRX period according to the indication information when the indication information indicates that the adjustment of the DRX period is permitted; the DRX period can be actively adjusted to a certain degree, and not only can the length be adjusted, but also the length can be adjusted to be short or unchanged; meanwhile, the state of the terminal is not limited, so that the terminal can adjust the DRX period conveniently; the problem that the scheme for adjusting the DRX period by the terminal in the prior art is inconvenient and incomplete is well solved.
In consideration of the fact that the terminal may be in different states, the present implementation provides corresponding specific strategies:
a first policy, wherein the step of transmitting request information for adjusting the DRX cycle to the base station comprises: when the terminal is in an idle state, the request information is sent to a base station in a preset beacon mode;
correspondingly, the step of receiving the indication information fed back by the base station according to the request information includes: and receiving the indication information fed back by the base station in a paging mode.
Specifically, the step of sending the request information to the base station in a preset beacon mode includes: when the base station is an original base station which allocates time-frequency resources to the terminal in advance, the request information is sent to the base station in a preset beacon mode on the time-frequency resources allocated to the terminal in advance by the base station;
when the base station is not the original base station which distributes time-frequency resources to the terminal in advance, controlling the terminal to enter a connection state and sending a resource request to the base station; receiving resource information and beacon information fed back by the base station according to the resource request; and sending the request information to a base station in a corresponding preset beacon mode on the corresponding time-frequency resource according to the resource information and the beacon information.
Further, before the sending the request information to the base station in a preset beacon manner, the method further includes: and monitoring system information, and judging whether the base station is an original base station which allocates time-frequency resources to the terminal in advance according to the system information.
This is mainly because the time-frequency resources used by the beacon and the transmitted beacon may not be used across base stations, otherwise there may be a risk that multiple terminals share the same beacon and time-frequency resources, resulting in a confusion of DRX adjustment.
In order to facilitate the original base station to release resources, in this embodiment, when sending a resource request to the base station, the DRX adjustment method further includes: and sending the original base station information to the base station.
In this embodiment, before the base station sends the request information to the base station in a manner of a preset beacon on a time-frequency resource pre-allocated to the terminal by the base station, the DRX adjustment method further includes: receiving resource information of time-frequency resources pre-distributed to the terminal by the base station and beacon information of beacons pre-distributed to the terminal by the base station, wherein the beacon information comprises a corresponding relation between request information and preset beacons; obtaining time-frequency resources which are pre-allocated to the terminal by the corresponding base station according to the resource information; and obtaining a preset beacon corresponding to the request information to be sent according to the beacon information.
Specifically, the step of adjusting the local DRX cycle according to the indication information includes: and adjusting the local DRX period according to the target period value in the indication information.
That is, after receiving the request message sent by the terminal, the base station selects a suitable target period value for the terminal according to its current capability status, and sends the target period value to the terminal.
In a second strategy, the step of sending the request information for adjusting the DRX cycle to the base station comprises: when the terminal is in the random access process, the request information is sent to a base station in a Radio Resource Control (RRC) signaling mode;
correspondingly, the step of receiving the indication information fed back by the base station according to the request information includes: and receiving the indication information fed back by the base station in a Radio Resource Control (RRC) signaling mode.
It can also be understood that, if the terminal needs to adjust the DRX cycle in the random access process, the request information may be carried in the interaction information with the base station in the random access process to implement DRX cycle adjustment.
In a third strategy, the step of sending the request information for adjusting the DRX cycle to the base station includes: when the terminal is in a connected state, the request information is sent to a base station in a special signaling mode;
correspondingly, the step of receiving the indication information fed back by the base station according to the request information includes: and receiving the indication information fed back by the base station in a dedicated signaling mode.
It can also be understood that a set of signaling is redesigned, which is dedicated to the terminal to adjust the DRX cycle in the connected state.
Further, after the receiving the indication information fed back by the base station according to the request information, the DRX adjusting method further includes: and controlling the terminal to enter an idle state when the indication information indicates that the DRX adjustment is refused.
For completeness of the scheme, in this embodiment, after the adjusting the local DRX cycle according to the indication information, the DRX adjusting method further includes: and feeding back a response message of receiving the indication information to the base station.
Further, before the sending the request information for adjusting the DRX cycle to the base station, the DRX adjusting method further includes: judging whether the DRX period needs to be adjusted or not according to the service requirement and the electric quantity information; if yes, constructing corresponding request information, and executing the step of sending the request information for adjusting the DRX period to the base station.
That is, when the terminal needs to adjust the DRX cycle, the request message is sent to the base station, which saves resources.
In summary, the method for adjusting DRX in discontinuous reception according to the embodiment of the present invention well solves the problem that the scheme for adjusting DRX cycle by the terminal in the prior art is inconvenient and imperfect.

In summary, the discontinuous reception DRX adjustment method provided in the second embodiment of the present invention well solves the problem that the scheme for adjusting the DRX cycle by the terminal in the prior art is inconvenient and imperfect.
The discontinuous reception DRX adjusting method provided by the embodiment of the present invention is further described below with reference to the terminal and the base station.
To solve the above technical problem, an embodiment of the present invention provides a method for adjusting DRX in discontinuous reception, so that a terminal UE can flexibly adjust a DRX cycle, and a network can acquire the change (the network needs to acquire the DRX cycle of the UE because the network needs to send a paging message when the UE wakes up).
There are three main implementations:
in the scheme 1, after the UE enters a connected state, the modification of the DRX is coordinated with a network through a special signaling, namely, the signaling for adjusting the DRX request is initiated after the terminal feeds back RRC connection completion information to a base station;
scheme 2, the UE modifies DRX in the process of random access RACH, reports 1 or more expected DRX values in RRC connection request information (carrying the ID of the terminal), receives an RRC connection establishment command fed back by the base station according to the RRC connection request, and carries an adjusted value, namely an adjustment target value of the terminal (if the UE only reports one value, the base station can directly feed back 'agree', and does not feed back to represent rejection);
and 3, coordinating the modification of DRX with the network by the UE without establishing connection, and sending a specific beacon, wherein each UE needs to allocate 1 or more beacons. The network (base station) allocates specific time-frequency resources to the UE in advance (when the terminal is in a connected state, the network allocates the specific time-frequency resources to the UE), the UE sends beacon in the time-frequency resources, the network determines which UE the UE belongs to according to the position of the time-frequency resources, and the network determines whether the UE is adjusted to be larger or smaller according to the beacon. The base station may also send an indication to the terminal to permit adjustment of DRX when feeding back information to the terminal.
The beacon value taking and updating operations are also required for the scheme 3.
The method comprises the following specific steps:
scheme 1 example:
when the UE wants to adjust the DRX period, the UE firstly enters an RRC _ connected state through random access, and then sends RRC signaling 'DRX change request' to the eNB and is attached with 1 or several expected DRX periods; the eNB feeds back 'DRX change permission' through RRC signaling and attaches 1 DRX period, and the UE adjusts the DRX period of the UE to the value after receiving the DRX period and feeds back the DRX period to the eNB through an RRC message 'DRXchange ACK' to inform that the DRX adjustment signaling is received.
Wherein the 'DRX change permission' may be placed in an RRCConnectionReconfiguration (RRC connection reconfiguration) message in the existing LTE protocol.
Wherein 'DRX change request' means that adjustment of DRX is requested, and the UE requests adjustment of DRX in the signaling and attaches a desired 1 or more DRX values;
'DRX change permission' means that DRX is permitted to be adjusted, the eNB allows the DRX cycle to be adjusted, and feeds back an adjusted cycle value;
'DRX change ACK' means that the UE receives a DRX adjustment message, and informs the eNB that the UE has received the DRX adjustment message.
Scheme 2 example 1:
as shown in fig. 3, includes:
step 31: UE initiates random access and sends a preamble to a base station eNB;
step 32: a base station feeds back uplink resources (UL grant) and a Temporary C-RNTI (cell radio Network Temporary Identifier) allocated to the UE;
step 33: the UE sends an RRC connection request to the base station and carries a UE ID (identity) and the desired DRX value(s);
step 34: after receiving the command, the base station selects a proper DRX value for the UE, feeds back an RRC connection establishment command to the UE and carries the selected DRX value;
step 35: the UE feeds back RRC connection establishment completion information to the base station and enters an RRC _ connected connection state;
step 36: and the subsequent base station side releases connection RRC connection release, and the UE returns to an idle state (enters RRC _ idle).
Scheme 2 example 2:
as shown in fig. 4, includes:
step 41: the UE sends a preamble (preamble) to a base station eNB;
in order to establish a wireless connection with the network.
Step 42: a base station feeds back uplink resources and a temporary C-RNTI (Cell radio network temporary Identifier) allocated to the UE;
and the base station allocates uplink scheduling resources for the UE according to the lead code.
Step 43: the UE transmits a DRX adjustment request (DRX change request) to the base station, and attaches a UE ID and expected 1 or more DRX values;
step 44: the base station feeds back a DRX adjustment permission (DRX change permission) and the selected target period value (DRX value) to the UE;
step 45: the UE sends a DRX adjustment reply message (DRX change ACK) to the base station, informs the base station of the reception of the message, and then returns to the RRC _ idle state.
The difference between this scheme and embodiment 1 is that the signaling for RRC connection establishment in steps 33 to 35 is modified, and a new RRC signaling (dedicated signaling) is designed: 'DRX change request', DRX change permission ', DRXchange ACK':
wherein, 'DRX change request' means that the DRX is requested to be adjusted, and the UE requests to adjust the DRX in step 43, and attaches the UE ID and the desired 1 or more DRX values, informs the network side which UE the UE is, and how much the DRX cycle is desired to be adjusted;
'DRX change permission' means that DRX is permitted to be adjusted, the network side allows the DRX period to be adjusted, and feeds back a selected target period value;
the 'DRX change ACK' means that the UE receives a DRX adjustment message, and informs the network that the UE has received the DRX adjustment message.
The group of signaling is dedicated to adjusting the DRX period, and the advantage is that the UE directly requests the eNB to change the DRX without the need of establishing RRC connection allocation resources at the network side. The adjusted UE can immediately return to the RRC _ idle state, so that more energy and resources are saved.
Scheme 3 example:
in the connected state, the eNB pre-allocates, to the UE, time-frequency resources dedicated to the UE and available for the idle state to use in the cell, and allocates, to all the UEs, 2 common beacon (beacon) codes (which may also be understood as a value of a beacon or the above-mentioned preset beacon), where beacon code 1 represents an extended DRX cycle and beacon code 2 represents a shortened DRX cycle. Of course, the UEs may not share the beacon code, or some UEs may share the beacon code, which is not limited herein.
When the UE is in an idle state, if the DRX cycle is to be extended (whether the DRX cycle is to be extended is determined mainly according to the service requirement and the power consumption), the UE monitors a system message, determines whether the UE still resides in the original cell, if so, indicates that a dedicated time-frequency resource allocated to the UE by the eNB is still valid, the UE transmits a beacon code 1 on the time-frequency resource, and after the eNB receives the beacon code, the DRX cycle of the UE stored in the eNB is extended. Optionally, the eNB informs the UE of the adjusted DRX cycle through the paging message paging. The UE may or may not inform the eNB after receiving the information.
If the UE judges that the cell is not the originally resident cell, the dedicated time-frequency resource allocated before is unavailable. The UE needs to enter a connected state to acquire dedicated time-frequency resources from the new eNB. The new eNB informs the original eNB through an X2 (between base stations) or S1 (between base stations and core network) interface that the UE has moved, and the original eNB releases the dedicated time-frequency resources allocated to the UE.
Specifically, when the terminal enters a connected state with a new base station, the terminal actively reports its own identity information, the new base station allocates resources to the terminal according to the identity information of the terminal, and before allocation, receives the identity information of the old base station reported by the terminal, and notifies the old base station to release the resources.
The scheme for the UE to adjust DRX in the new eNB is similar to the above-mentioned scheme, and is not described herein again.
In addition, in this embodiment, when the base station does not support the function of the terminal for actively adjusting the DRX cycle or the resource allocation is completed, the base station may also notify the terminal that the adjustment is rejected, and the terminal directly enters an idle state.
As can be seen from the above, in the prior art, the network configures the same DRX for the UE in all cells, and the UE can send a message to the base station to request to adjust the DRX length, but cannot flexibly adjust the DRX length and the DRX length, and must enter a connected state; the scheme provides three specific methods for flexibly adjusting the DRX, can adjust in the connection state and also can not enter the connection state adjustment, and well solves the problem that the scheme for adjusting the DRX period by the terminal in the prior art is inconvenient and incomplete.
