Background
The RRC (Radio Resource Control) state of an LTE (Long Term evolution) system includes two states, RRC idle and RRC connected. In order to improve the power saving performance, a drx (discontinuous reception) operation mode is adopted in the RRC connected state, allowing the mobile terminal to monitor the physical downlink control channel discontinuously.

Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
Example one
Referring to fig. 1, a flowchart illustrating a first step of a method for processing channel quality anomaly according to the present invention is shown, which may specifically include the following steps:
Where spectral efficiency is the symbol transmission rate within a unit frequency band. The greater the spectral efficiency, the better the channel quality; the smaller the spectral efficiency, the worse the channel quality.
The spectrum efficiency threshold is used for judging whether the frequency efficiency of the mobile terminal is normal or not, and can be determined according to the mobile terminal with poor channel quality in an actual application scene, and the embodiment of the invention does not limit the frequency efficiency threshold.
Specifically, the step of judging whether the channel quality is abnormal according to the spectrum efficiency includes: firstly, a Media Access Control (MAC) layer of a base station determines whether a spectrum efficiency is less than or equal to a spectrum efficiency threshold; then, if the spectrum efficiency is less than or equal to the spectrum efficiency threshold value, the channel quality is abnormal; and if the spectral efficiency is greater than the spectral efficiency threshold, the channel quality is normal.
The signal receiving strength of the current cell is the strength of the reference signal received by the mobile terminal from the current serving cell. The larger the signal receiving strength of the current cell is, the better the channel quality is; the smaller the signal reception strength of the current cell, the worse the channel quality.
The first intensity threshold is used for judging whether the signal receiving intensity of the mobile terminal to the current cell is too small. It is to be understood that the first intensity threshold may be set according to an actual application scenario, and the embodiment of the present invention does not limit the setting.
Specifically, the step of determining whether the channel quality is abnormal according to the signal reception strength of the current cell includes: firstly, judging whether the signal receiving intensity of the current cell is less than or equal to a first intensity threshold value; then, if the signal receiving intensity of the current cell is less than or equal to a first intensity threshold value, determining that the channel quality is abnormal, and reporting an A2 event to a base station; and if the signal receiving intensity of the current cell is greater than the first intensity threshold value, determining that the channel quality is normal, and not reporting an A2 event to the base station.
The signal reception strength to the neighboring cell is the strength at which the mobile terminal receives the reference signal from the neighboring cell. The signal receiving strength to the adjacent cell is greater than the signal receiving strength to the current cell, which indicates that the more likely the user is to switch from the current cell to the adjacent cell, the worse the channel quality; the signal reception strength for the neighboring cell is less than the signal reception strength for the current cell, indicating that the less likely it is that the user is to switch from the current cell to the neighboring cell, the better the channel quality.
The second intensity threshold is used for judging whether the signal receiving intensity of the mobile terminal to the adjacent cell is larger than the signal receiving intensity of the current cell. It can be understood that the second intensity threshold is a positive value, and may be set according to an actual application scenario, which is not limited in the embodiment of the present invention.
Specifically, the step of determining whether the channel quality is abnormal according to the signal reception strength of the neighboring cell includes: firstly, calculating the intensity difference value of the channel receiving intensity of the adjacent cell and the signal receiving intensity of the current cell; then, judging whether the difference value is greater than or equal to a second intensity threshold value; finally, if the difference is greater than or equal to the second intensity threshold, determining that the channel quality is abnormal, and reporting an A3 event to the base station; and if the difference is smaller than the second intensity threshold, determining that the channel quality is normal, and not reporting the A3 event to the base station.
It can be understood that in practical application, three different ways to determine whether the channel quality of the mobile terminal is abnormal may be determined simultaneously or only one of them may be determined. In practical application, in order to judge the channel quality accurately, three methods can be simultaneously adopted to judge whether the channel quality is abnormal.
And 102, if the spectrum efficiency of the mobile terminal is smaller than a preset spectrum efficiency threshold value and/or the report information of the mobile terminal to the specified event is received, exiting the discontinuous reception mode of the mobile terminal or stopping normal scheduling of the mobile terminal.
Wherein, exiting the Discontinuous Reception (Discontinuous Reception) mode can be realized by sending a DRX configuration instruction, and the base station can directly stop normal scheduling for the mobile terminal.
It is to be appreciated that the mobile terminal changes from the active state DRX active state to the DRX inactive state after exiting the discontinuous reception mode or stopping normal scheduling of the mobile terminal.
The embodiment of the invention can reduce the influence of the channel quality on the communication quality of the DRX activation user by exiting the discontinuous reception mode of the mobile terminal or stopping the normal scheduling of the mobile terminal, thereby improving the user experience.
Specifically, the exit from the discontinuous reception mode of the mobile terminal needs to be controlled by MAC and higher layer software, and the stop of the normal scheduling of the mobile terminal can be controlled by the MAC layer.
In the embodiment of the present invention, it is determined whether the spectrum efficiency of a mobile terminal is less than or equal to a preset spectrum efficiency threshold, and/or whether information reported by the mobile terminal to a specified event is received, where the specified event at least includes: the method comprises the following steps that a first specified event and a second specified event are carried out, wherein the first specified event comprises that the signal receiving intensity of a mobile terminal to a current cell is smaller than or equal to a preset first intensity threshold value, and the second specified event comprises that the difference between the signal receiving intensity of the mobile terminal to an adjacent cell and the signal receiving intensity of the mobile terminal to the current cell is larger than or equal to a preset second intensity threshold value; and if the frequency spectrum efficiency of the mobile terminal is smaller than a preset frequency spectrum efficiency threshold value and/or the report information of the mobile terminal to the specified event is received, exiting the discontinuous reception mode of the mobile terminal or stopping normal scheduling of the mobile terminal. Therefore, the problems that the DRX states of a base station and a terminal are inconsistent and downlink receiving cannot be carried out due to missed detection of a physical downlink control channel when the channel quality is poor are solved, the problem that the user experience is reduced is solved, the DRX configuration can be removed or the mobile terminal can be stopped to be scheduled when the channel quality is poor, the influence of the channel quality on the communication quality of a DRX activation user is reduced, and the beneficial effect of the user experience is improved.
Example two
Referring to fig. 2, a flowchart illustrating steps of a second embodiment of a method for processing channel quality anomalies according to the present invention is shown, which may specifically include the following steps:
This step can refer to the detailed description of step 101, and is not described herein again.
This step can refer to the detailed description of step 102, and is not described herein again.
Optionally, in another embodiment of the present invention, step 202 includes sub-step 2021:
substep 2021, adding a first instruction for exiting the discontinuous reception mode of the mobile terminal to a new message, and sending the new message to the mobile terminal.
Wherein, the new message is a Radio Resource Control (RRC) reconfiguration message.
When the channel quality is judged to be abnormal according to the spectrum efficiency and the A3 event, an air interface RRC reconfiguration message needs to be added separately and carries a de-configuration message so as to indicate the mobile terminal to exit the discontinuous reception mode.
Optionally, in another embodiment of the present invention, step 202 includes sub-step 2022:
substep 2022, adding a first instruction for exiting the discontinuous reception mode of the mobile terminal to a preset configuration message, and sending the configuration message to the mobile terminal.
The preset configuration message is an air interface message for configuring the pilot frequency measurement event.
After the mobile terminal reports the event a2, the base station configures the pilot frequency measurement event for the terminal through an air interface message, and carries a DRX de-configuration or configuration message. Step 203, if the spectrum efficiency of the mobile terminal is greater than the sum of the preset spectrum efficiency threshold and the preset spectrum efficiency offset, starting a discontinuous reception mode of the mobile terminal or resuming normal scheduling of the mobile terminal.
The preset spectrum efficiency deviation is used for improving the judgment accuracy, and avoiding frequent quitting/starting of a discontinuous reception mode and stopping/resuming normal scheduling of the mobile terminal by edge users with spectrum efficiency above and below a spectrum efficiency threshold. It can be understood that the preset spectral efficiency offset may be set according to an actual application scenario, and the embodiment of the present invention does not limit the preset spectral efficiency offset.
The embodiment of the invention can start the discontinuous reception mode and recover the normal scheduling of the mobile terminal when the channel quality is judged to be normal through the spectrum efficiency.
Optionally, in another embodiment of the present invention, step 203 includes sub-step 2031:
substep 2031, adding a second instruction for starting the discontinuous reception mode of the mobile terminal to the new message, and sending the new message to the mobile terminal.
In practical application, the MAC layer may notify the higher layer software to issue a new message when it determines that the channel quality is abnormal according to the spectrum efficiency.
It is understood that the new message is the new message in sub-step 2021, except that the new message carries the second instruction to turn on the discontinuous reception mode of the mobile terminal, and the new message in sub-step 2021 carries the first instruction to exit the discontinuous reception mode of the mobile terminal.
The preset time period may be set according to an actual application scenario, and is not limited in the embodiment of the present invention. In practical application, a preset first offset strength may be further configured in the event of a2, so as to improve the accuracy of the determination, avoid frequent exiting/starting of the discontinuous reception mode and stop/resume normal scheduling of the mobile terminal by the user whose signal reception strength is above or below the first strength threshold.
It is to be understood that the first offset strength may be set according to an actual application scenario, and the embodiment of the present invention does not limit the first offset strength.
When the embodiment of the invention judges that the channel quality is normal through the A2 event, the discontinuous reception mode is started, and the normal scheduling of the mobile terminal is recovered.
Optionally, in another embodiment of the present invention, step 204 comprises sub-steps 2041:
substep 2041, adding a second instruction for starting the discontinuous reception mode of the mobile terminal to the new message, and sending the new message to the mobile terminal.
In practical application, when the base station receives the report of the a3 event, the new message is issued by the higher layer software.
It is understood that the new message is the new message in sub-step 2021, except that the new message carries the second instruction to turn on the discontinuous reception mode of the mobile terminal, and the new message in sub-step 2021 carries the first instruction to exit the discontinuous reception mode of the mobile terminal.
The preset time period may be set according to an actual application scenario, and is not limited in the embodiment of the present invention.
In practical application, a preset second offset strength may be configured in the event of a3, so as to improve the accuracy of the determination, avoid frequent exiting/starting of the discontinuous reception mode and stop/resume normal scheduling of the mobile terminal for users at the edge of two adjacent cells. It can be understood that the preset second offset strength may be set according to an actual application scenario, and the embodiment of the present invention does not limit the preset second offset strength.
The embodiment of the invention can start the discontinuous reception mode and recover the normal scheduling of the mobile terminal when the channel quality is judged to be normal according to the A3 event.
Optionally, in another embodiment of the present invention, step 205 comprises sub-step 2051:
substep 2051, adding a second instruction for starting the discontinuous reception mode of the mobile terminal to the configuration message, and sending the configuration message to the mobile terminal.
In practical applications, when the base station receives the report of the a2 event, the base station issues a configuration message through higher-layer software.
It is to be understood that this configuration message corresponds to the preset configuration message in sub-step 2022, with the difference that it carries the second instruction to turn on the discontinuous reception mode of the mobile terminal, whereas the preset configuration message in sub-step 2022 carries the first instruction to exit the discontinuous reception mode of the mobile terminal.
It can be understood that steps 203, 204, and 205 are three different ways to determine whether the channel quality of the mobile terminal is recovered to normal, and may be determined at the same time or only one of them. In practical application, in order to judge the channel quality accurately, three methods can be simultaneously adopted to judge whether the channel quality is recovered to be normal.
In the embodiment of the present invention, it is determined whether the spectrum efficiency of a mobile terminal is less than or equal to a preset spectrum efficiency threshold, and/or whether information reported by the mobile terminal to a specified event is received, where the specified event at least includes: the method comprises the following steps that a first specified event and a second specified event are carried out, wherein the first specified event comprises that the signal receiving intensity of a mobile terminal to a current cell is smaller than or equal to a preset first intensity threshold value, and the second specified event comprises that the difference between the signal receiving intensity of the mobile terminal to an adjacent cell and the signal receiving intensity of the mobile terminal to the current cell is larger than or equal to a preset second intensity threshold value; and if the frequency spectrum efficiency of the mobile terminal is smaller than a preset frequency spectrum efficiency threshold value, and/or receiving report information of the mobile terminal to a specified event. Therefore, the problems that the DRX states of a base station and a terminal are inconsistent and downlink receiving cannot be carried out due to missed detection of a physical downlink control channel when the channel quality is poor are solved, the problem that the user experience is reduced is solved, the DRX configuration can be removed or the mobile terminal can be stopped to be scheduled when the channel quality is poor, the influence of the channel quality on the communication quality of a DRX activation user is reduced, and the beneficial effect of the user experience is improved. In addition, it is also possible to reconfigure DRX and resume normal scheduling for the mobile terminal after the channel quality becomes good.
