Fig. 1 shows a flowchart of an interference monitoring method under a sensing system according to an embodiment of the present invention, and as shown in fig. 1, the interference monitoring method under the sensing system according to the embodiment is as follows.
Step 101: the monitoring control center receives a first message sent by a site A in the perception system.
The first message is that the station A monitors a frequency band F ═ F in the process of monitoring idle resources1,f2]At time interval T ═ T1,t2]When the mobile terminal is in a busy state, sending the message;
the first message includes: the frequency band F ═ F1,f2]The time period T ═ T1,t2]Station a of the sensing system during a time period T ═ T1,t2]Internal use frequency band F ═ F1,f2]Time duration t0And location information L of site A of the sensing system0。
Step 102: after receiving the first message, the monitoring control center searches a plurality of other stations B with distance difference values with the station A within a preset range and position information of the other stations B from a public database storing position information of all stations of at least one perception system.
Step 103: the monitoring control center respectively sends request messages to the other stations B, and the request messages are used for enabling the other stations B to acquire the time T ═ T of the station B1,t2]Internal use frequency band F ═ F1,f2]Time duration ti。
Step 104: the monitoring control center receives respective time T ═ T transmitted by the other stations B1,t2]Internal use frequency band F ═ F1,f2]Time duration tiWhere i is 1,2,. n, n is the number of the other stations B.
Step 105: the monitoring control center is used for monitoring the state of the equipment according to a preset formulaObtaining at time T ═ T1,t2]In the frequency band F ═ F1,f2]A total duration T _ total used by the station a and a plurality of further stations B; when the total duration is greater than a preset first threshold, determining that the frequency band F ═ F1,f2]At time T ═ T1,t2]Without being disturbed.
In this embodiment, the monitoring control center in fig. 1 is a hardware device, and one monitoring control center may be arranged in units of a district or a city, or certainly, the district or the city may be divided into a plurality of sub-areas, and one monitoring control center is arranged in each sub-area to monitor interference information in the sub-area.
Therefore, in the interference monitoring method under the sensing system of this embodiment, the monitoring control center receives a message that a certain frequency band sent by a station in the sensing system is occupied for a long time in a certain period of time, and the monitoring control center determines whether the frequency band is occupied illegally in the period of time, that is, whether the frequency band is interfered, by combining the total duration of the frequency band used by the station and surrounding stations in the period of time. The method solves the problem that the existing interference monitoring method cannot monitor the interference under the sensing system. In addition, the interference monitoring method described in this embodiment does not need to increase the extra sensing amount of the sensing system station, and only needs the sensing system station to send the station position and the actual duration using a certain frequency band within a certain period of time to the monitoring control center, so that the implementation is simple.
Under the sensing system, each industry user establishes a sensing system, a plurality of sensing systems share resources, and the sensing systems of a plurality of industry users use the resources in a dynamic mode, so that when network resource interference occurs, an interference monitoring method is needed for monitoring and analyzing. Fig. 2 shows a flowchart of an interference monitoring method under the sensing system according to a second embodiment of the present invention, and as shown in fig. 2, the interference monitoring method under the sensing system according to the present embodiment is as follows.
Step 201: when monitoring idle resources, site A monitors frequency band F ═ F1,f2]At time interval T ═ T1,t2]While in a busy state, the public database is queried.
In this step, the station a is a station under a certain sensing system G, and the station a monitors that a frequency band F ═ F is monitored in the process of monitoring idle resources1,f2]At time interval T ═ T1,t2]Internally busy, including: if station a is in time period T ═ T1,t2]Determining the frequency band F ═ F1,f2]Available probability is less thanA preset second threshold value, then determining that the frequency band F ═ F1,f2]At time interval T ═ T1,t2]The inside is in a busy state;
the frequency band F ═ F1,f2]The available probability is that station a is in the time period T ═ T1,t2]Internally monitoring said frequency band F ═ F1,f2]The number of times of idling and the time period T ═ T1,t2]The ratio of the minimum monitoring times of the site A is specified.
The preset value of the second threshold is related to the number of sensing systems sharing resources, for example, n sensing systems sharing resources are provided, so that if the sensing systems use resources averagely, the probability of using the resources by each sensing system is 1/n, and if the time delay caused by the factors such as site monitoring of each sensing system is considered, the preset value of the second threshold may be (1/n) × 50%. Of course, the second threshold may also be set to (1/n) × 60%, etc., depending on the actual delay.
Here, the time period T ═ T1,t2]The unit of (b) may be an hour or a day, and is generally an integer greater than 0.
When the frequency band F ═ F1,f2]When the available probability is smaller than the preset second threshold, the sensing system site cannot obtain enough resources for service transmission, and the sensing system site considers that the frequency band resources may be interfered, so that the information is sent to the monitoring control center to inform the monitoring control center that the frequency band may be interfered.
Step 202: judging whether the frequency band F ═ F exists in the public database1,f2]If not, step 203a is executed, otherwise, step 203b is executed.
In this step, the public database stores fixed frequency bands in advance, and these frequency bands have specific uses and cannot be used by the station. If the frequency band F is stored in the public database[f1,f2]If the frequency band is proved to be a reserved fixed frequency band and cannot provide resource service for the station, the frequency band F ═ F can be obtained1,f2]Is not disturbed.
Step 203 a: the monitoring control center receives a first message sent by a site A in a perception system, wherein the first message comprises: the frequency band F ═ F1,f2]The time period T ═ T1,t2]Station a of the sensing system during a time period T ═ T1,t2]Internal use frequency band F ═ F1,f2]Time duration t0And location information L of site A of the sensing system0。
Step 203 b: determining the frequency band F ═ F1,f2]Is not disturbed.
Step 204: after receiving the first message, the monitoring control center searches a plurality of other stations B with distance difference values with the station A within a preset range and position information of the other stations B from a public database storing position information of all stations of at least one perception system.
In this step, the public database stores the location information of all stations of at least one sensing system in advance, and after receiving the first message sent by the station a, the monitoring control center starts to query the location information of a plurality of adjacent stations B from the public database.
Step 205: the monitoring control center respectively sends request messages to the other stations B, and the request messages are used for enabling the other stations B to acquire the time T ═ T of the station B1,t2]Internal use frequency band F ═ F1,f2]Time duration ti。
Step 206: the monitoring control center receives respective time T ═ T transmitted by the other stations B1,t2]Internal use frequency band F ═ F1,f2]Time duration tiWhere i is 1,2,. n, n is the number of the other stations B.
In this step, after receiving the request message sent by the monitoring control center, the other stations B respectively set their own time T ═ T1,t2]Internal use frequency band F ═ F1,f2]Time duration tiIs sent to the monitoring control center, and the monitoring control center receives respective time T ═ T sent by the other stations B respectively1,t2]Internal use frequency band F ═ F1,f2]Time duration tiThe information of (1).
Step 207: the monitoring control center is used for monitoring the state of the equipment according to a preset formulaObtaining at time T ═ T1,t2]In the frequency band F ═ F1,f2]The total duration T total used by said station a and a plurality of further stations B.
Step 208: and judging whether the total time length T _ total is greater than a preset first threshold value, if so, executing a step 209a, otherwise, executing a step 209 b.
In this step, the monitoring control center performs monitoring according to a preset formulaObtaining at time T ═ T1,t2]In the frequency band F ═ F1,f2]And judging whether the total duration T _ total occupied by the legal system is greater than a preset first threshold value T _ thredhold or not, if the total duration T _ total is greater than the T _ thredhold, executing the step 207a, and otherwise, executing the step 207 b. Here, the preset value of the preset first threshold T _ thredhold is set with a time interval T' ═ T2-t1In connection with this, the predetermined value of the first threshold T _ thredhold is generally (T)2-t1)×μ,0.5≤μ＜1。
Step 209 a: determining theFrequency band F ═ F1,f2]At time T ═ T1,t2]Without being disturbed.
In this step, it is determined that T _ total > T _ thdhold, which means that the frequency band F is ═ F1,f2]At time T ═ T1,t2]Is normally used by a station a and a plurality of adjacent stations B, and thus the frequency band F ═ F can be determined1,f2]At time T ═ T1,t2]Without being disturbed.
Step 209 b: determining the frequency band F ═ F1,f2]At time T ═ T1,t2]Is internally disturbed.
In this step, it is determined that T _ total is less than or equal to T _ thredhold, which means that the frequency band F is ═ F1,f2]At time T ═ T1,t2]The frequency band F may be analyzed or checked in a subsequent process because the frequency band F is not normally used by the station a and a plurality of neighboring stations B and may be interfered by an illegal station1,f2]And interference is eliminated due to interference, so that the resources are recovered to a normal state.
Therefore, in this embodiment, steps 201 and 202 are added on the basis of the first embodiment, and the station a monitors that the frequency band F is ═ F in the process of monitoring the idle resources1,f2]At time interval T ═ T1,t2]When the user is in a busy state, whether the frequency band F is stored in a public database or not is firstly inquired1,f2]The message mode is used for judging the frequency band F ═ F1,f2]Frequency resources which cannot be used by the station of the perception system and are reserved for certain specific purposes, wherein fixed frequency bands which have specific purposes and cannot be used by the station are stored in the public database in advance. If the frequency band F ═ F is stored in the public database1,f2]Then, the frequency band F ═ F can be directly obtained1,f2]Messages not illegally occupied, determiningThe frequency band F ═ F1,f2]Interference is not received, and interference monitoring time is saved. If the frequency band F ═ F is not stored in the public database1,f2]Then, the monitoring control center needs to monitor the time period T ═ T according to the station a and a plurality of neighboring stations B1,t2]Inner pair of frequency bands F ═ F1,f2]Using the total duration of time to determine said F ═ F1,f2]Whether interference is received.
The embodiment is an implementation manner under the condition that each station does not know the frequency resources reserved for the specific use and cannot be used by the station of the sensing system by default, and of course, if the frequency resources reserved for the specific use and cannot be used by the station of the sensing system are pre-stored or pre-known in each station of the sensing system, when the station monitors that a certain frequency band is in a busy state, the station itself will judge whether the frequency band in the busy state is in a normal working state according to the stored message, so as to determine whether to send the first message to the monitoring control center, without checking a public database.
