Description
Technical Field
The present application relates to the field of communications technologies, and in particular, to an anti-interference implementation method and apparatus.
Background
Due to the complex electromagnetic environment, the civil frequency equipment is mainly communication operator base stations, broadcast launching towers and other equipment, and the civil frequency equipment is mainly short waves, ultrashort waves, microwaves, talkbacks and the like. These devices are likely to cause interference to the wireless broadband communication network, resulting in serious consequences such as communication quality degradation and even communication interruption.
For the characteristics of a partial interference source in a full Time domain and a partial frequency band, that is, interference of an interference signal of a continuous partial frequency band in a working frequency band, based on the characteristic of uplink and downlink Time Division transmission of LTE TDD (Time Division Long Term Evolution Time Division duplex), an interference detection function of an LTE uplink subframe is used to find whether interference exists in a system. The specific implementation mode can be as follows: the Interference strength is judged by calculating an IOT (Interference over Thermal) value, IOT values on continuous effective subframes are calculated by calculating all PRBs (Physical Resource blocks) in bandwidth configuration, when the IOT values at the same PRB position are all higher than a certain threshold value, the system can be judged to be in an Interference state, an anti-Interference avoidance mechanism needs to be adopted, and the current Interference threshold is always a fixed Interference threshold value configured according to experience.
For example: after the cell is activated, an interference period detection timer is started, whether continuous PRBs are interfered is periodically judged, 100 PRBs exist by taking an LTE cell with a bandwidth of 20M as an example, the bandwidth of each PRB is 180KHz, and an IOT value is independently calculated for each PRB. When the subframes of the base station are configured as 2 uplink and 2 downlink within 10ms, that is, within one radio frame, 4 uplink subframes can calculate the IOT value within 10ms, and when the IOT values at the same PRB position within 10ms are consistent (the IOT value is higher than the threshold), it is considered as interference outside the LTE system, and the interference position of the PRB needs to be determined. And judging whether the PRB position is in a control channel or a service channel, starting an anti-interference avoidance mechanism, and performing pre-configuration on a fixed interference threshold value of the IOT value in the realization process according to an empirical value or a test result.
Based on the scheme disclosed by the prior art, it can be determined that the fixed interference threshold set according to human experience in the prior art does not have an accurate standard, so that the requirement of accurate judgment is often not met, if the interference threshold is set too low, unnecessary interference processing is often caused, the originally available PRB resources are limited, so that air interface resources are wasted, and the service processing performance is influenced; and the interference threshold value is set too high, if the interference is not avoided in time, the problem of service drop or access failure can be caused.

Detailed Description
In the interference detection mode of the LTE uplink subframe in the prior art, whether interference exists in the system is judged according to a fixed interference threshold set by human experience, and the fixed interference threshold does not have an accurate standard, so that the requirement of accurate judgment cannot be met, and the following problems can be caused:
1, due to uncertainty of human experience, the interference threshold fixed value is easily to be configured improperly and adjusted repeatedly.
2, after the interference threshold is configured as a fixed value, the flexibility is poor, and the interference threshold cannot be adaptively adjusted according to the service condition or the external environment change, so that the accuracy of interference detection is poor.
If the specified interference threshold value is unreasonable, the system does not reach the interference state, and the interference may be judged to exist, so that the detected PRB is deducted, the processing capability of the base station on the service is directly influenced, precious air interface resources are wasted, and if the control channel is used, the user access or the user with the service is possibly influenced; when strong interference is received, if the threshold configuration is high, it is determined that no interference is received, and user drop or access failure is caused. Therefore, the detection of the external interference is closely related to the configuration of the interference threshold to a great extent, and the proper configuration of the interference detection threshold plays a crucial role in the accuracy of the interference detection.
Based on the above problems in the prior art, an embodiment of the present application provides an anti-interference implementation method, and a question answering idea of the method is as follows:
s1, judging whether to start the interference threshold training process, if yes, obtaining the training parameter of the pre-configured interference threshold; the training parameters comprise single interference training threshold duration and interference training threshold times;
s2, acquiring a current interference threshold value to determine the interference state information of an uplink physical resource block PRB of a current cell, and judging whether a single interference training threshold duration is reached;
and S3, when the single interference training threshold duration is reached, determining the uplink service rate of the cell under the current interference threshold value, and judging whether the interference training threshold number is reached, if so, determining the maximum value of a plurality of uplink service rates acquired within the interference training threshold number range, and taking the interference threshold value corresponding to the maximum value as the interference threshold value of the periodic interference detection processing.
Based on the method provided by the embodiment of the application, when the system interference detection is carried out, a fixed test experience value is not taken, but a proper interference threshold value is determined according to the service rate test condition, and the purpose of configuring the proper interference threshold value is achieved through multiple self-adaptive adjustments, so that the interference detection is more accurate, and the interference avoidance is more accurate and effective.
The method and apparatus provided by the embodiments of the present application are further described in detail below with reference to the accompanying drawings and specific application scenarios:
example one
As shown in fig. 1, an embodiment of the present application provides an anti-interference implementation method, which may specifically include the following steps:
considering the most serious external interference, namely, directly influencing the access of a new user, the influence on the uplink service rate of a cell is considered as an index for judging whether the interference threshold configuration is appropriate or not when the new user accesses, so that the method provided by the embodiment of the application can trigger the training of the interference threshold value to obtain the optimized interference threshold value (namely, the interference threshold value corresponding to the maximum value of the uplink service rate within a certain range) when the new user accesses. In addition, in order to ensure that the interference threshold value training has the minimum influence on the cell service, only one UE is required to perform training at the same time when the interference threshold value training is performed.
in the embodiment of the present application, when a new User Equipment (UE) accesses, a base station is triggered to acquire a training parameter of a preset interference threshold, where the training parameter of the preset interference threshold may be a pre-stored default value set according to an artificial experience value.
In addition, in order to ensure accuracy of interference detection, in the embodiment of the present application, when determining whether a cell is interfered, the interference state of each PRB may be comprehensively determined for how many consecutive PRBs are interfered and the number of consecutive interferences of each PRB. Therefore, in the embodiment of the present application, a specific implementation manner of determining whether an uplink PRB of a current cell is in an interference state may be:
determining interference state information of a plurality of continuous uplink PRBs according to the current interference threshold value, and acquiring continuous interference times of each uplink PRB in the plurality of uplink PRBs;
and determining whether each uplink PRB is in an interference state or not according to the interference state information and the continuous interference times.
102, acquiring a current interference threshold value to determine interference state information of an uplink Physical Resource Block (PRB) of a current cell, and judging whether a single interference training threshold duration is reached;
in the embodiment of the present application, in order to obtain an interference threshold that most reasonably and optimally meets an actual requirement, a plurality of different interference thresholds need to be set to perform specific training on a cell, and then it is determined according to different downlink service rates under different interference thresholds how the interference thresholds do not cause excessive limitation on resources of the cell or cause a user to drop. In this embodiment, therefore, an optimized interference threshold value may be determined in a cyclic manner based on the duration of a single interference training threshold and the number of times of interference training thresholds.
The single interference training threshold duration and the number of times of the interference training threshold may be set according to actual empirical values, and are not specifically limited herein.
103, when the single interference training threshold duration is reached, determining the uplink service rate of the cell under the current interference threshold value, and judging whether the interference training threshold number is reached, if so, turning to 104; otherwise, go to step 105;
and step 104, determining the maximum value of the plurality of uplink service rates obtained within the interference training threshold frequency range, and taking the interference threshold value corresponding to the maximum value as the interference threshold value of the periodic interference detection processing.
In the embodiment of the present application, a plurality of interference thresholds may be formed based on the adjustment step size, then the uplink traffic rate of the cell under each interference threshold is determined, and the threshold is determined to be optimized according to the size of the uplink traffic rate. Therefore, the interference threshold value determined by the embodiment of the application can ensure that the detection of the interference is more accurate, so that the interference evasion is more accurate and effective.
In order to ensure that the measured uplink service rate can correctly reflect the condition of the cell, some factors influencing the interference state of the cell are excluded in the interference threshold training process of the method in the embodiment of the present application, for example, periodic interference avoidance processing may not be performed in the interference threshold training process, and the specific implementation may be:
if the current cell is in an interference state, closing an interference avoidance mechanism; and after the interference threshold corresponding to the maximum value is taken as the interference threshold of the periodic interference detection processing, starting the interference avoidance mechanism.
Example two
In order to describe the method provided by the embodiment of the present application in more detail, the following describes in further detail an anti-interference implementation method provided by the embodiment of the present application with reference to the flow shown in fig. 2, and specific implementations may include:
step 202, the RRC initiates an interference threshold training process, and sends an interference threshold training request message to the MAC ((media access control, media access control); the request message carries a single interference training threshold duration and PRB interference state information, where the interference state information includes:
and determining whether a plurality of continuous uplink PRBs are interfered or not according to the current interference threshold value, the number of the continuously interfered PRBs, and the continuous interference frequency information of each uplink PRB in the plurality of uplink PRBs.
In the step, if the interference threshold training is carried out firstly at present, the PRB interference state information is obtained after the RRC carries out interference judgment on the uplink PRB of the current cell based on an initial default interference threshold value; if the training is not the first training, the interference threshold value for judging the interference state information is the interference threshold value obtained after adjusting the step length.
When the RRC determines the interference state of the PRB, it may be determined by combining multiple factors, where the multiple factors may include: the continuous interference suffered by the PRB (namely whether a plurality of PRBs are continuously interfered), the continuous interference frequency of the same PRB and the like.
Step 203, after receiving the request message, the MAC replies an Interference _ Train _ Response message to the RRC after the configured single Interference training threshold duration is reached according to the PRB Interference state information issued by the RRC; the message carries the uplink service rate of the cell;
step 204, the RRC records the cell uplink service rate under the interference training threshold value, then determines whether the configured maximum interference training frequency has been reached, and if so, proceeds to step 205; otherwise, go to step 206;
step 205, selecting a target interference threshold with the maximum uplink service rate to be issued to the RRM, as an interference threshold to be subsequently provided to the periodic interference detection processing;
step 206, after recording the interference threshold and the corresponding cell rate for each time, obtaining a new interference threshold (the new interference threshold is the sum of the interference threshold adjustment step and the interference threshold adopted in the previous interference training) according to the configured interference threshold adjustment step, and going to step 202, initiating a new interference threshold training process based on the new interference threshold.
In the embodiment of the application, the interference threshold value is trained for multiple times based on the training times of the interference threshold, the interference threshold value corresponding to each training is different, and the training process is ended after the maximum training time of the interference threshold is reached, so that the optimized interference threshold value can be determined through the uplink service rates under different interference threshold values.
