It should be understood that the described embodiments are only some embodiments of the invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

These terms are only used to distinguish one processing module from another. For example, a first processing module may also be referred to as a second processing module, and similarly, a second processing module may also be referred to as a first processing module without departing from the scope of embodiments of the present invention.

Similarly, the phrases "if determined" or "if detected (a stated condition or event)" may be interpreted as "when determined" or "in response to a determination" or "when detected (a stated condition or event)" or "in response to a detection (a stated condition or event)", depending on the context.

It should be understood that the term "and/or" as used herein is merely one type of association that describes an associated object, meaning that three relationships may exist, e.g., a and/or B may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.

The embodiment of the invention provides an information processing method, which is applied to an unlicensed frequency band LTE system sharing frequency spectrum with other communication systems based on an LBT technology.

The method is performed in a base station operating in an unlicensed frequency band, as shown in fig. 1, and includes:

101. and monitoring the parameters to be detected of the terminal when the terminal runs the Long Term Evolution (LTE) service.

The LTE service may be an uplink LTE service or a downlink LTE service.

The parameter to be detected may be any one of Block Error Rate (BLER), Retransmission Times (Retransmission Times), and Signal-to-noise ratio difference (Delta Signal to Interference plus noise ratio) of the LTE Signal, or a combination of any two or a combination of any three of these.

Specifically, the snr difference refers to the difference between the current snr and the snr at the designated transmission.

It should be noted that the block error rate, the number of retransmissions, the snr difference value, and the waiting detection parameter may reflect the LTE signal transmission quality of the terminal. When the signal transmission quality is continuously poor, other system signals (such as Digital Enhanced Cordless Telecommunications (DECT) system signals) may occur, and interference is generated on the LTE signals.

102. And comparing the to-be-detected parameter with the target parameter value to obtain a comparison result.

The target parameter value is a standard for judging good and poor signal transmission quality in the LTE system with the unlicensed frequency band, and may also be a threshold value at which signals of other systems may appear.

In a specific implementation manner, when the parameter to be detected is the block error rate, the target parameter is the target block error rate, the value of the target block error rate is greater than or equal to 0 and less than or equal to 0.1, and usually a default value of 0.07 is taken; when the parameter to be detected is the retransmission times, the target parameter is the target retransmission times, the value of the target parameter is greater than or equal to 1 time and less than or equal to 6 times, and a default value of 3 is usually adopted; when the parameter to be detected is the signal-to-noise ratio difference, the target parameter is the target signal-to-noise ratio difference, the target signal-to-noise ratio difference is greater than or equal to 1 db and less than or equal to 40 db, and the default value is usually 2.

103. And obtaining the duration of the parameter to be detected which is greater than or equal to the target parameter value according to the comparison result.

104. And if the duration is greater than or equal to the target duration, starting detection of a preset communication system signal.

The preset communication system signal refers to other communication system signals which may be present, and may be a DECT system signal or a Wi-Fi signal (wireless fidelity signal).

When the parameter to be detected is greater than or equal to the target parameter value and lasts for a period of time, namely the duration is greater than or equal to the target duration, it is considered that other communication system signals may appear, and at the moment, the detection of the preset communication system signals is started.

The target duration may be a value greater than or equal to 1ms (millisecond) and less than or equal to 30000ms, and is typically a default value of 100 ms.

In the information processing method provided by the embodiment of the invention, the detection of the signal of the preset communication system is started only when the parameter to be detected is greater than or equal to the target parameter and the duration time is greater than or equal to the target duration time by monitoring the parameter to be detected of the terminal running the LTE service, and the starting of the detection has high flexibility. According to the technical scheme provided by the embodiment of the invention, when the parameter to be detected is greater than or equal to the target parameter and the duration is greater than or equal to the target duration, the interference of the signal of the preset communication system is considered to possibly occur, the detection of the signal of the preset communication system is started only at the moment, the LTE service does not need to be frequently and periodically stopped, the unnecessary LBT of the base station can be avoided, the performance of the LTE system working in an unauthorized frequency band is improved, and the communication requirement of the LTE service can be better met.

In addition, the method provided by the embodiment of the invention has higher accuracy for judging whether other communication system signals appear or not by monitoring each parameter to be detected (or the combination of the parameters to be detected).

Further, with reference to the foregoing method flow, another possible implementation manner of the embodiment of the present invention provides the following method flow for a specific implementation manner of how to determine that the duration of the parameter to be detected is greater than or equal to the target parameter value in step 103, as shown in fig. 2, step 103 includes:

1031. and taking the moment when the parameter to be detected is greater than or equal to the target parameter value as the initial moment.

In one possible implementation, the initial time may be marked as the current system frame number × 10+ the current subframe number.

1032. And taking the moment when the parameter to be detected is smaller than or equal to the target parameter value as the termination moment.

It should be noted that, since the LTE system frame number range is 0 to 1023, the situation of system frame number cycling needs to be considered when recording the termination time.

1033. And taking the time interval between the initial time and the termination time as the duration of the parameter to be detected which is greater than or equal to the target parameter value.

Further, in combination with the foregoing method flow, in order to improve the accuracy of determining whether other system signals occur, for example, if the monitored terminal is located at a cell edge, the block error rate, the retransmission times, and the difference between the signal to noise ratio of the terminal may be higher due to the fact that the received signal to noise ratio is weaker and interference possibly from an intra-frequency neighbor cell, so that whether other communication system signals occur or not is determined by mistake. Therefore, in order to increase the randomness of the monitored terminal, the percentage of the number of all terminals with the parameters to be detected being larger than or equal to the target parameters in all terminals operating the LTE service in the cell can be calculated to assist in judging whether other communication system signals appear. Therefore, another possible implementation manner of the embodiment of the present invention further provides the following method flow, which is executed after step 102, as shown in fig. 3, and further includes:

102', determining the ratio of the number of the terminals with the parameters to be detected being larger than or equal to the target parameters to the total number of the terminals running the LTE service.

Step 103 is specifically executed as the following steps:

1034. and when the ratio is greater than or equal to the target ratio, obtaining the duration of the parameter to be detected which is greater than or equal to the target parameter value according to the comparison result.

After the ratio of the number of the terminals with the parameters to be detected being greater than or equal to the target parameters in a certain direction (uplink or downlink) to the total number of the terminals running the LTE service in the direction is greater than or equal to the target ratio, the duration of the parameters to be detected being greater than or equal to the target parameters is further determined, and whether other communication system signals appear can be judged more accurately and more quickly.

It should be noted that, in an optional implementation manner, after obtaining the duration of the parameter to be detected in a certain direction (uplink or downlink) that is greater than or equal to the target parameter value, a ratio of the number of terminals whose duration is greater than or equal to the target duration in the direction to the total number of terminals that are running the LTE service in the direction is determined, and then whether to start detection on signals of other communication systems is determined according to the size of the ratio.

Further, with reference to the foregoing method flow, if the duration of the parameter to be detected is greater than or equal to the target parameter value and is greater than or equal to the target duration, before starting detection of the preset communication system signal, in order to prevent interference, the LTE service currently running needs to be stopped or switched, so that another possible implementation manner of the embodiment of the present invention provides the following three possible implementation manners for implementation of step 104.

The first implementation, as shown in fig. 4, includes:

1041. if the current cell has the GBR service in operation, rejecting a terminal access request and a GBR service request of the current cell, and stopping the non-GBR service in operation of the current cell after the GBR service in operation is finished, and starting the detection of the signal of the preset communication system.

The LTE traffic may include GBR traffic and non-GBR traffic. Wherein, GBR is called Guaranteed Bit Rate, and translated into Guaranteed Bit Rate, GBR service refers to service with lowest Guaranteed Rate, and generally includes ductility sensitive service such as voice call, video chat, etc.; non-GBR traffic, which refers to traffic without the lowest guaranteed rate (only the maximum rate limit), generally includes traffic that is not ductility insensitive, such as file downloading, web browsing, etc.

The terminal access request means a request that a new terminal requests to access a current cell so as to run an LTE service in the current cell.

Considering the experience of the user, the operation of the GBR service needs to be guaranteed, so if there is a GBR service in operation in the current cell, the first implementation manner adopts a waiting strategy, and starts the detection of the signal of the preset communication system only after stopping the non-GBR service in the cell after all the GBR services in operation in the cell are finished.

The second implementation, as shown in fig. 5, includes:

1042. if the current cell has the GBR service in operation, the terminal access request and the GBR service request of the current cell are rejected, a timer is started, and the terminal in which the GBR service is in operation and the terminal in which the non-GBR service is in operation of the current cell are sequentially switched to the adjacent cells.

1043. After the timer is overtime, if the current cell has the GBR service running, the non-GBR service running in the current cell is stopped after the GBR service running in the current cell is finished, and the detection of the signal of the preset communication system is started.

The duration range set by the timer can be between 1000ms and 60000ms, and a default value of 1000ms is usually adopted.

Considering the experience of the user, the operation of the GBR service needs to be guaranteed, so if there is a GBR service in operation in the current cell, the second implementation method adopts a handover strategy, a timer sets a specified time period, the GBR service in operation in the cell is sequentially handed over to the adjacent cell within the specified time period, if all GBR services in operation at the specified time end are handed over, the non-GBR service starts to be handed over, if not, in order to prevent the neighbor cell from being fully loaded or from being unable to be handed over due to other reasons, the handover is stopped, after the remaining GBR services in operation are finished, the non-GBR service in operation in the cell is stopped, and then the detection of the signal of the preset communication system is started.

The third implementation, as shown in fig. 6, includes:

1044. if the current cell does not have the GBR service in operation, rejecting a terminal access request and a GBR service request of the current cell, and starting detection of a signal of a preset communication system after stopping the non-GBR service in operation of the current cell.

If there is no GBR service in operation in the current cell, in order to prevent the LTE service from continuously interfering with other communication systems, the third embodiment adopts a stopping strategy, that is, immediately stops the non-GBR service in operation in the current cell, and immediately starts the detection of the signal of the preset communication system.

Compared with the prior art, by the three implementation manners, before the detection of the preset communication system signal is started, the mutual continuous interference between the LTE system and other communication systems can be eliminated more quickly as long as all LTE services (including GBR service and non-GBR service) in operation in the cell are always waited to finish.

With reference to the above method flow, the embodiment of the present invention determines whether to start a specific algorithm for detecting DECT system signals based on monitoring each parameter to be detected, and provides the following six possible implementation manners:

first, the parameters to be detected are block error rate:

step 1, the eNB normally operates the LTE service in the current cell, and sets FIRST _ DECT _ MEAS as TRUE.

Wherein, eNB is called evolved Node B in english, i.e. evolved base station.

Where FIRST _ DECT _ MEAS refers to the FIRST DECT system signal detection, TRUE.

Step 2, if the downlink transmission BLER of one UE in the UE of the cell in the RRC _ CONNECTED state is less than or equal to TARGET _ BLER, setting FIRST _ DECT _ MEAS as TRUE and waiting for next downlink scheduling and repeating the step 2 again; if the downlink transmission BLER of one UE in the UE of the cell in the RRC _ CONNECTED state is more than or equal to TARGET _ BLER, the following judgment and steps are executed:

if the FIRST _ DECT _ MEAS is TRUE, it means that the window length statistics is performed for the FIRST Time, the Initial Time Initial _ Time of the statistics is set to be the current system frame number × 10+ the current subframe number, the end Time Last _ Time is set to be the Initial _ Time, and meanwhile, the FIRST _ DECT _ MEAS is set to be FALSE;

if FIRST _ DECT _ MEAS is FALSE, meaning that the window statistics have already started, Last _ Time is set to current system frame number × 10+ current subframe number.

Wherein, UE is called User Equipment in all, Chinese meaning terminal; TARGET _ BLER refers to the TARGET block error rate, i.e., the TARGET parameter value; FALSE.

The UE in the RRC (Radio Resource Control) CONNECTED state refers to that the terminal is operating an LTE service.

And 3, if Last _ Time-initial _ Time < Time _ WINDOW, repeating the step 2 and the step 3 (wherein, when the step 2 is repeated, the judgment of the step 2 should be carried out on the UE selected for the first Time, but one UE is not selected again to carry out the judgment of the step 2).

Wherein, TIME WINDOW, translated into TIME WINDOW, refers to target duration.

And 4, if the Last _ Time-initial _ Time is not less than the Time _ WINDOW, starting the detection of the DECT system signal.

Secondly, the parameters to be detected are the repetition times:

Step 2, if the retransmission times of downlink transmission of one UE in the UEs of the cell in the RRC _ CONNECTED state is less than or equal to TARGET _ RETRANS _ COUNTER, setting FIRST _ DECT _ MEAS as TRUE and waiting for next downlink scheduling to repeat step 2 again; if the retransmission times of downlink transmission of one UE in the UEs with the cell in the RRC _ CONNECTED state is more than or equal to TARGET _ RETRANS _ COUNTER, the following judgment and steps are executed:

if FIRST _ DECT _ MEAS is TRUE, it means that the window length statistics is performed for the FIRST Time, and the Initial Time Initial _ Time of the statistics is set to be current system frame number × 10+ current subframe number, and the end Time Last _ Time is set to be Initial _ Time; meanwhile, setting FIRST _ DECT _ MEAS as FALSE;

The TARGET _ retransmission _ COUNTER refers to a TARGET retransmission number, that is, a TARGET parameter value.

And 3, if Last _ Time-initial _ Time < Time _ WINDOW, repeating the step 2 and the step 3.

Thirdly, the parameters to be detected are the signal-to-noise ratio difference value:

Step 2, if the FIRST _ DECT _ MEAS is TRUE, the downlink SINR of one UE in the UEs in the RRC _ CONNECTED state in the cell is reduced by more than or equal to DELTA _ SINR for the last time (i.e., the signal-to-noise ratio difference), setting the FIRST _ DECT _ MEAS as TRUE and waiting for next downlink scheduling to repeat the step 2 again; if the descending extent of the downlink SINR of one UE in the UE of the cell in the RRC _ CONNECTED state relative to the last time is more than or equal to DELTA _ SINR, (marking the last SINR as ORIGINAL _ SINR), executing the step a;

if the FIRST _ DECT _ MEAS is FALSE, the downlink SINR-ORIGINAL _ SINR of one of the UEs in the RRC _ CONNECTED state in the cell is less than or equal to DELTA _ SINR, setting the FIRST _ DECT _ MEAS to TRUE, and repeating the step 2; if the downlink SINR-ORIGINAL _ SINR of one UE in the UE of the cell in the RRC _ CONNECTED state is more than or equal to DELTA _ SINR, executing the step b;

a. if FIRST _ DECT _ MEAS is TRUE, it means that the window length statistics is performed for the FIRST Time, and the Initial Time Initial _ Time of the statistics is set to be current system frame number × 10+ current subframe number, and the end Time Last _ Time is set to be Initial _ Time; meanwhile, setting FIRST _ DECT _ MEAS as FALSE;

b. if FIRST _ DECT _ MEAS is FALSE, meaning that the window statistics have already started, Last _ Time is set to current system frame number × 10+ current subframe number.

Where DELTA _ SINR refers to the target signal-to-noise ratio difference, i.e. the target parameter value.

Fourthly, the parameter to be detected is the block error rate, and the ratio of the number of the terminals with the block error rate larger than or equal to the target block error rate to the total number of the terminals running the LTE service is taken into consideration:

Step 2, if the BLER of any UE in the UE of the cell in the RRC _ CONNECTED state is more than or equal to TARGET _ BLER, entering step 3; otherwise, the process is restarted from step 1.

Step 3, if ((the number of UE with downlink BLER being more than or equal to TARGET _ BLER)/the total number of UE doing downlink service) being more than or equal to TARGET _ UE _ PERCENTAGE, executing the following judgment and steps, otherwise, restarting from step 1:

if FIRST _ DECT _ MEAS is TRUE, it means that the window length statistics is performed for the FIRST Time, and the Initial Time Initial _ Time of the statistics is set to be current system frame number × 10+ current subframe number, and the termination Time Last _ Time is set to be Initial _ Time; meanwhile, setting FIRST _ DECT _ MEAS as FALSE;

Where TARGET _ UE _ PERCENTAGE represents the TARGET ratio.

And 4, if Last _ Time-initial _ Time < Time _ WINDOW, repeating the steps 2, 3 and 4.

And 5, if the Last _ Time-initial _ Time is not less than the Time _ WINDOW, starting the detection of the DECT system signal.

Fifthly, the parameter to be detected is the repetition frequency, and the ratio of the number of the terminals with the repetition frequency greater than or equal to the target repetition frequency to the total number of the terminals running the LTE service is taken into consideration:

Step 2, if the retransmission times of the downlink transmission of any UE in the UE of the cell in the RRC _ CONNECTED state is more than or equal to TARGET _ RETRANS _ COUNTER, entering step 3; otherwise, the process is restarted from step 1.

Step 3, if ((the number of downlink retransmission times is more than or equal to the number of UE of TARGET _ RETRANS _ COUNTER)/the total number of UE doing downlink service) is more than or equal to TARGET _ UE _ PERCENTAGE, executing the following judgment and steps, otherwise, restarting from step 1:

Step 2, if the FIRST _ DECT _ MEAS is TRUE, the reduction amplitude of the downlink SINR of one UE in the UEs in the RRC _ CONNECTED state in the cell relative to the previous time is less than or equal to DELTA _ SINR, and waiting for the next downlink scheduling and repeating the step 2 again; if the descending amplitude of the downlink SINR of one UE in the RRC _ CONNECTED state of the cell relative to the last time is more than or equal to DELTA _ SINR, (marking the last SINR as ORIGINAL _ SINR), entering the step 3;

if the FIRST _ DECT _ MEAS is FALSE, the downlink SINR-ORIGINAL _ SINR of one of the UEs in the RRC _ CONNECTED state in the cell is less than or equal to DELTA _ SINR, setting the FIRST _ DECT _ MEAS to TRUE, and repeating the step 2; if the downlink SINR-ORIGINAL _ SINR of one UE in the UE with the cell in the RRC _ CONNECTED state is larger than or equal to DELTA _ SINR, the procedure goes to step 3.
