Description

Method and terminal device for realizing discontinuous reception

Technical field

The present invention relates to the field of communications technologies, and in particular, to a method and a terminal device for implementing discontinuous reception.

Background of the invention

DRX (Discontinuous Reception) technology is one for LTE (Long Term) Evolution, Long Term Evolution) Terminal power saving technology in communication systems. The DRX technology specifically allows the terminal to be in a certain period of time: part of the time is in an active state, and another part of the time is in a dormant state. By this implementation, the purpose of saving terminal power consumption can be achieved.

In the DRX working mode, the terminal needs to determine when it is active and when to process the sleep state according to parameters such as the length of the activation period, the activation time point, and the length of the sleep period. Specifically, the terminal may obtain parameters such as a length of the activation period, an activation time point, and a length of the sleep period through the received configuration message. After obtaining the corresponding parameters, the terminal enters the DRX state, so that in the DRX working mode, the start time and timing of the corresponding timers (such as the activation timer, sleep timer, etc. in the DRX state) can be determined based on each parameter. duration.

Due to DRX for terminals and eNBs (evolved Node The timing synchronization requirement of the B-evolved base station is relatively high. Therefore, after the terminal enters the DRX working mode, each timer needs to be started at an accurate time to ensure synchronization between the terminal and the eNB, that is, the terminal and the eNB can be simultaneously Active state or hibernation state Therefore, the reliability of the air interface data transmission is ensured, and the problem of air interface data loss is avoided, that is, if the eNB transmits data during the period in which the terminal sleeps, the corresponding data is lost.

However, in the prior art, after the terminal enters the network, when the DRX configuration parameter configuration is performed on the terminal through the reconfiguration message, in the period from the start of the DRX configuration parameter configuration to the parameter configuration success, the message takes time and the message is sent. There is a possibility of loss of transmission, so the eNB cannot determine whether the terminal is in an active state or in a sleep state. As a result, the eNB cannot accurately transmit the air interface data during this time.

Summary of the invention

An object of the present invention is to provide a method and a terminal device for implementing discontinuous reception, so that the reliability of air interface data transmission can be ensured during the discontinuous reception parameter configuration process.

A method of implementing discontinuous reception, comprising:

After receiving the discontinuous reception configuration parameter information carried in the RRC reconfiguration message, entering a continuous activation state, and exiting the continuous activation state after a predetermined period of time elapses;

It can be seen from the foregoing technical solution that, in the technical solution, after adopting the DRX configuration parameter information carried in the reconfiguration message, the terminal device maintains the continuous activation period after a period of continuous activation period, and thus can exit the continuous activation state. It is ensured that the data transmitted by the network side terminal device can be reliably received by the terminal device during the configuration process of the DRX configuration parameter, thereby effectively improving the reliability of data transmission between the terminal device and the network side.

Mode for carrying out the invention

The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the drawings in the embodiments of the present invention. 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 obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

In the embodiment of the present invention, after the terminal device receives the DRX configuration parameter information in the reconfiguration message, the terminal device maintains a continuous activation period for a period of time, so that the air interface data can be reliably transmitted between the terminal and the network side.

In a specific implementation process, as shown in FIG. 1 , the method for implementing the discontinuous reception provided by the embodiment of the present invention may specifically include:

Step 11, receiving RRC (Radio Resource Control Protocol, Radio Resource Control) After the non-continuous receiving configuration parameter information carried in the reconfiguration message enters a continuous activation state;

Step 12, exiting the continuous activation state after a predetermined period of time;

That is, the terminal device can keep the continuous activation period for a period of time after receiving the reconfiguration message, and exit the continuous activation state after satisfying the threshold for a period of time;

In this step, the specific time length of the corresponding predetermined time period may be determined according to the time required for the DRX configuration parameter configuration to be successful, so that after the continuous activation period ends, the terminal device may enter the DRX mode based on the newly configured DRX configuration parameter. Realizing reliable communication with the network side. For example, the average time value or the maximum value of the time required for the DRX configuration parameter configuration to be successfully obtained may be determined based on statistics to determine a specific time length value of the predetermined time period;

Step 13: Enter the discontinuous reception state according to the received discontinuous reception configuration parameter information, that is, enter the normal DRX state with the newly configured DRX configuration parameter.

It should be noted that, in the foregoing step 12, the corresponding operation of exiting the continuous activation state after a predetermined period of time may be specifically, but not limited to, implemented by any of the following methods:

Method 1: Implement by timer

After receiving the discontinuous reception configuration parameter information, the continuous activation timer is started, and the terminal device is in a continuous activation state before the continuous activation timer expires; for example, the timing duration of the continuous activation timer may be, but is not limited to, n times The activation timer timing duration in the continuous reception state, and is an integer with n greater than 1. After the continuous activation timer expires, the continuous activation state is exited; or, after the continuous activation timer expires, the continuous activation state is maintained until the activation timer in the DRX state is started, and the continuous activation state is exited.

Method 2: Implement by counter

After receiving the discontinuous reception configuration parameter information, the counter is started. When the activation timer in the DRX state is determined to be started N times according to the counter, the continuous activation state is exited, and N is an integer greater than 1.

Through the foregoing implementation manner, the terminal can maintain a continuous activation period after receiving the DRX configuration information for a period of time, and then exit the continuous activation state, and enter the normal DRX state based on the newly configured DRX configuration parameter. This ensures that the data transmitted by the network side terminal device can be reliably received by the terminal device during the DRX configuration parameter configuration process, thereby improving the reliability of data transmission.

Step 22: After receiving the DRX configuration parameter information, the terminal device starts a continuous activation timer.

Specifically, the timing duration of the corresponding consecutive activation timer may be determined according to the time required for the DRX configuration parameter to be successfully configured. For example, the timing of the corresponding continuous activation timer is based on statistics to obtain the average time required for the DRX configuration parameter to be successfully configured. The value is determined.

Further, the timing of the continuous activation timer may be set to n times the duration of the activation timer in the DRX state, and is a positive integer with n greater than 1, and the value of the parameter n may be configured according to the network condition; The timing of the activation timer in the corresponding DRX state may be obtained according to the received DRX configuration parameter information;

Step 23: The terminal device is in a continuous activation state before the continuous activation timer expires;

The terminal device can normally perform operations such as receiving air interface data in the continuous activation state; specifically, the function operation required by the terminal device in the continuous activation state may be equivalent to the function operation required by the activation state terminal device in the DRX mode, such that In the process of receiving the DRX configuration parameter information and configuring the DRX configuration parameter, the terminal device can still communicate with the network side and reliably receive the air interface data transmitted from the network side.

In the above process, after the continuous activation timer expires, the continuous activation state may be exited, or the continuous activation state may be continued until the activation timer in the DRX state is started, and then the continuous activation state is exited.

With the application embodiment, the terminal device can maintain a continuous activation period of a period of time after receiving the DRX configuration parameter information in the RRC reconfiguration message, so as to accurately receive data sent by the network side, thereby improving data transmission reliability.

Step 31: The terminal device receives an RRC reconfiguration message carrying DRX configuration parameter information.

Step 32: Start a continuous activation timer with a timing duration of n times the OD timer, and enter a continuous activation period, that is, enter a continuous activation state;

The OD timer timing duration is obtained based on the received RRC reconfiguration message carrying the DRX configuration parameter information.

Step 33, it is determined whether the continuous activation timer has timed out, if not, proceed to step 34, otherwise, go to step 35;

In step 34, the continuous activation period is maintained to ensure that the terminal device can reliably receive the air interface data sent by the network side, and step 33 is performed.

Step 35: Maintain a continuous activation period, and when the OD timer starts, exit the continuous activation period and enter the DRX normal timing mode, that is, enter the DRX mode by using the DRX configuration parameter obtained based on the RRC reconfiguration message.

Application Example 3

As shown in FIG. 4, in the application embodiment, the specific implementation of the corresponding step 11 and step 12 may include the following steps:

Step 41: The terminal device receives an RRC reconfiguration message carrying DRX configuration parameter information.

The counter may be counted up by 0, 1, 2, ..., N; or, may be counted down, such as by N, ..., 2, 1, 0; N is an integer greater than one;

Step 43: Whether the counter value of the counter is greater than N (that is, whether the counter count value is greater than N), if yes, proceed to step 44; otherwise, perform step 45; wherein the value of N can be configured as needed, for example, Not limited to configuration 2, 3 or 4, etc.;

In this step, if the counter uses the accumulated count, it is directly determined whether the statistically obtained counting result is greater than N. If the counter is counted down, the counter can be decremented from N, and the step needs to determine whether the counter is decremented to 0. To determine whether the counter value of the counter is greater than N.

In step 44, the continuous activation period is exited.

In step 45, the continuous activation period is maintained, and step 43 is performed.

Through the above processing, the terminal device can exit the continuous activation state at the beginning of the Nth OD timer and enter the normal DRX state.

With the above technical solution, the eNB processing in the ambiguous period (ie, the eNB cannot determine the period in which the eNB is in the active or dormant state) is more efficient, and avoids a large number of retransmissions and false detections caused by the eNB and the terminal state misalignment. problem.
