It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

These terms are only used to distinguish one element from another. For example, a first xx script may be referred to as a second xx script, and similarly, a second xx script may be referred to as a first xx script, without departing from the scope of the present disclosure.
As shown in fig. 1, in an embodiment, a communication security management method based on signal strength is provided, which is applied to a communication base station, and specifically includes the following steps:
step S110, broadcasting base station information to the outside, and receiving a user identification code returned by the mobile terminal aiming at the base station information;
step S120, network registration is carried out on the received user identification code;
step S130, completing network registration, and distributing communication frequency band and paging time interval for the user identification code;
step S140, acquiring the signal intensity of the mobile terminal corresponding to the user identification code according to a set frequency;
step S150, adjusting the communication frequency band and the paging interval according to the acquired signal intensity;
and step S160, data transmission is carried out on the adjusted communication frequency band and the paging interval.
In one embodiment, the base station information broadcasted by the base station includes, but is not limited to, LAI (location area number, LAI is composed of two parts, CID and LAC. CID are operator identifiers of SCDMA network, LAC is a location area code of SCDMA network), BSIC (base station identity code 9), CGI (global cell identity), cellID (cell identity), URA (UTRAN, including registration areas of WCDMA and TD-SCDMA), and other encoded information, which is used for unique pointing of the base station, and facilitates the network to transmit information to the base station. After receiving the base station information broadcasted by the base station, the mobile terminal needs to periodically return a user identification code to the base station, so that the network can confirm the state and position of the terminal.
In one embodiment, after receiving the subscriber identity uploaded by the mobile terminal, the network registers the subscriber identity and stores the subscriber identity in the basic relative storage area, so that the network knows that the subscriber represented by the subscriber identity is located within the coverage of the base station, and thus communicates with the subscriber through the base station. This is a common procedure of the prior art.
In one embodiment, after the network registration is completed, the base station allocates a communication band and a paging interval to the user or the mobile terminal with the user identification code, and the base station communicates with the mobile terminal only in the allocated band and the paging interval.
In an embodiment, the main difference from the general prior art is that, after the communication frequency band and the paging interval are allocated, the scheme provided by the present invention further obtains the signal strength of the mobile terminal corresponding to the user identification code at a set frequency at a fixed time, and adjusts the communication frequency band and the paging interval according to the obtained signal strength, thereby implementing dynamic adjustment of the communication frequency band and the paging interval, so that a potential monitoring party cannot obtain continuous data, and thus protecting data security during transmission.
The method provided by the invention can dynamically adjust the connection link between the mobile terminal and the base station according to the signal intensity after establishing the communication connection and regularly changing the communication frequency band and the paging time sharing, so that a third party can not stably track the communication link, thereby avoiding the information from being continuously monitored and ensuring the safety of data in the data transmission stage.
As an alternative of the present invention, the allocating a communication band and a paging interval for the user identification code includes:
acquiring a first occupancy rate of each current frequency band, and selecting a plurality of frequency bands from low to high according to the first occupancy rate;
and acquiring the second occupancy rate of each time interval of each selected frequency band, selecting the time interval with the lowest second occupancy rate to obtain the paging time interval, and selecting the frequency band where the paging time interval is located to obtain the communication frequency band.
In one embodiment, for any frequency band, the first occupancy rate is equal to the ratio of the current number of devices (or users) in the frequency band to the maximum device (or user) accommodation capacity in the frequency band.
In one embodiment, a communication cycle is set in any frequency band, each cycle is divided into several time periods, and a device or a user communicates with a base station only in one fixed time period of each cycle of a specific frequency band. The second occupancy rate of each time interval herein refers to a ratio of the current number of devices (or users) in the time interval to the maximum device (or user) accommodating amount in the time interval in a certain frequency band.
In one embodiment, the number of frequency bands selected according to the first occupancy rate of the frequency bands is not less than 3.
As an alternative of the present invention, the acquiring the signal strength of the mobile terminal corresponding to the user identification code according to the set frequency includes:
sending intensity detection data carrying the user identification code according to a set frequency in the current communication frequency band and the paging interval;
receiving intensity feedback data returned by the mobile terminal aiming at the intensity detection data;
determining communication time delay according to the intensity feedback data;
and searching the corresponding signal strength according to the communication time delay.
In one embodiment, the set frequency may be 2-5 times of the communication period between the mobile terminal and the base station. In this embodiment, the strength detection data is used for detecting the signal strength, and the content of the strength detection data is not important, but the signal strength is obtained through the transceiving time delay of the data, and even if a potential third party can acquire data propagated in a space, the potential third party cannot know the data receiving time of a base station or a terminal, so that the signal strength cannot be acquired, the hopping result of a subsequent communication frequency band and time period cannot be known, and continuous tracking cannot be realized.
In one embodiment, the intensity feedback data is substantially identical to the intensity detection data in data content and volume, thereby avoiding asymmetry of results due to differences in the data itself. In this embodiment, the sending time of the base station carried by the strength detection data and the sending time of the mobile terminal carried by the strength feedback data may be a first communication delay from the sending time of the strength detection data and the time when the mobile terminal receives the strength detection data, and the sending time of the strength feedback data and the time when the mobile terminal receives the strength feedback data may be a second communication delay from the sending time of the strength feedback data and the time when the mobile terminal receives the strength feedback data. After the communication delay is obtained, the mobile terminal and the base station can obtain corresponding signal strength through table lookup respectively, and the corresponding relation table of the communication delay and the signal strength is shared in the process of establishing communication between the mobile terminal and the base station for the first time. In this embodiment, it should be noted that the correspondence between the communication delay and the signal strength is preset, and is not equal to the real delay under the signal strength, and the real delay is also affected by a distance, an obstacle, and the like, and has no reference meaning.
As an alternative of the present invention, the adjusting the communication band and the paging interval according to the acquired signal strength includes:
sequencing the frequency bands from low to high according to the first occupancy rates of the frequency bands;
in each frequency band, sequencing each time interval from low to high according to the second occupancy rate of each time interval;
calculating the ratio of the searched signal intensity to a preset intensity threshold;
and multiplying the ratio by a given coefficient, then rounding, and selecting the frequency band and the time period in the corresponding sequence according to the rounding result.
In one embodiment, the predetermined strength threshold is the strongest signal that the mobile terminal can receive, and is generally set to the strongest signal sent by the base station. The ratio of the searched signal intensity to the preset intensity threshold ranges from 0 to 1, and the signal intensity is multiplied by a given coefficient and then amplified. For example, if the given coefficient is 15 and the given coefficient corresponds to 15 frequency bands, the ratio ranges from 0 to 15, an integer value from 0 to 15 is obtained after rounding, and the frequency band and the time period corresponding to the sequence are obtained. For example, the ratio is 0.238, multiplied by a given factor of 10 to obtain 2, and the second time interval in the second frequency band is selected as the new communication link. It should be noted that, in this embodiment, the occupancy rates of the frequency bands and the time periods also change at any time, so that the mobile terminal can continuously adjust the link where the mobile terminal is located in this manner, and obtain higher communication quality.
As shown in fig. 2, an embodiment of the present invention further provides a communication security management method based on signal strength, which is applied to a mobile terminal, and the communication security management method based on signal strength includes:

returning intensity feedback data for the intensity detection data;
determining communication time delay according to the intensity detection data;
and searching the corresponding signal strength according to the communication time delay.
