Description
Technical Field
The embodiment of the invention relates to the technical field of mobile communication, in particular to a mobile terminal shielding method and an interference base station.
Background
With the continuous development of mobile communication technology, the issue of secret leakage in mobile phone communication is also being regarded. Because the wireless channel has openness, the communication information of the mobile phone can be intercepted and positioned, tracked and monitored by using corresponding receiving equipment. However, in a special environment such as a conference room, a prison, and a national important government or military department, it is not desirable to perform mobile communication in order to prevent the mobile communication from being compromised. Therefore, the signal shielding device can be used for cutting off the contact between the mobile phone and the base station, so that any communication tool and receiving equipment cannot obtain the information of the mobile phone.
At present, a signal shielding scheme for signal synchronization interference is proposed, which mainly includes: scanning wireless signals transmitted by a mobile terminal in a shielding area, and judging whether the captured wireless signals are known signals to be shielded; the known signal to be shielded is interfered by the shielding equipment, so that the normal sending of the signal to be shielded is influenced.
The interference of the shielding equipment on the known signal to be shielded is mainly that the shielding equipment transmits high-power white noise as an interference signal, so that the signal-to-noise ratio of a received signal of the base station is low, a wireless signal transmitted by a mobile terminal in a shielding area cannot be normally demodulated from the received signal, and the signal shielding between the mobile terminal in the shielding area and the base station is realized.
However, since the interference signal has a certain coverage, when the shielding device interferes the known signal to be shielded to transmit a high-power interference signal, the wireless signal transmitted by the mobile terminal that does not need to be shielded within the coverage of the interference signal is also affected by the interference signal, so that the base station cannot normally demodulate the wireless signal transmitted by the mobile terminal that does not need to be shielded.
Therefore, according to the existing shielding scheme based on the interference signal, the high-power interference signal blocks the communication between the mobile terminal and the base station in the shielding area, and simultaneously, the interference is also caused to the normal communication between the mobile terminal and the base station which do not need to be shielded, so that the service quality of the terminal user which does not need to be shielded is reduced.
Therefore, there is a need to provide a shielding scheme that effectively reduces communication interference to mobile terminals that do not require shielding.

Detailed Description
The technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings, and it is obvious that the described embodiments are only some embodiments of the present invention, 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.
As used in this application, the terms "module," "device," and the like are intended to encompass a computer-related entity, such as but not limited to hardware, firmware, a combination of hardware and software, or software in execution. For example, a module may be, but is not limited to: a process running on a processor, an object, an executable, a thread of execution, a program, and/or a computer. For example, an application running on a computing device and the computing device may both be a module. One or more modules may reside within a process and/or thread of execution and a module may be localized on one computer and/or distributed between two or more computers.
As mentioned in the background, existing shielding schemes based on high power interfering signals have the problem of communication interference to the wirelessly shielded mobile terminals.
In view of the above-mentioned drawbacks of the prior art, the inventor of the present application considers that an interfering base station for shielding a mobile terminal can be obtained by modifying a wireless base station device used by an operator and setting a central processor. When the target area is in the shielding period, the interference base station controls the preset shielding control parameters and the shielding service type through the central processing unit, so that the mobile terminal in the signal coverage range is forcibly absorbed, the mobile terminal to be shielded which is forcibly absorbed is subjected to targeted service shielding processing, and communication interference on the mobile terminal which does not need to be shielded is avoided.
Further, when the target area is in the non-shielding period, the interference base station can be compatible with the function of the public network base station, broadcast the initial control parameter and provide normal mobile communication service for the mobile terminal in the signal coverage range; or, more preferably, the signal coverage of the target area during the non-shielding period can be enhanced through the signal distribution system, so that the terminal capacity of the area can be improved.
In the present application, a target area refers to an area where signal shielding needs exist within a set time or periodically, such as an examination room, a conference room, and the like, and the target area has a shielding period and a non-shielding period. On the premise of ensuring that the wireless signal of the interference base station can cover the target area, the interference base station can be arranged in or around the target area according to actual requirements.
The technical scheme of the invention is explained in detail in the following with the accompanying drawings.
Referring to fig. 1, an exemplary flowchart of a mobile terminal screening method according to one embodiment of the present invention is shown.
As shown in fig. 1, a mobile terminal shielding method according to an embodiment of the present invention may include the following steps:
s110: and if the interference base station judges that the shielding triggering condition is met, acquiring a shielding control parameter and a shielding service type corresponding to the target area.
Specifically, the shielding trigger condition is that the current shielding state of the target area is a shielding period.
Specifically, after the interference base station is started, the central processing unit may detect a current shielding state of the target area, and when the current shielding state of the target area is in a shielding period, the interference base station determines that a shielding trigger condition is satisfied. Wherein the shielding state of the target region may include: a mask period and a non-mask period.
In practical application, the current shielding state of the target area can be detected according to the current time and a preset shielding demand time range of the target area. When detecting that the current time is within the preset shielding requirement time range of the target area, the central processing unit of the interference base station can determine that the current shielding state of the target area is the shielding period.
Optionally, the current shielding state of the target area may also be detected by the number of mobile terminals currently establishing connection with the interfering base station in the target area, or the number of mobile terminals in the target area in a set time period with the current time as a node. For example, when the number of mobile terminals currently establishing connection with the interfering base station in the target area exceeds a first threshold, it may be determined that the current shielding state of the target area is a shielding period; or, when the number of mobile terminals in the target area exceeds the second threshold within a set time period taking the current time as the node, it may be determined that the current shielding state of the target area is the shielding period.
In the embodiment of the invention, after the interference base station judges that the shielding triggering condition is met, the shielding control parameter and the shielding service type corresponding to the target area can be acquired so as to carry out targeted shielding subsequently.
The shielding control parameter corresponding to the target area includes a cell parameter preset for the interfering base station according to an actual situation of the target area, and specifically includes at least one of the following: a first maximum transmit power, a first priority parameter, and a first cell reselection parameter and a first cell handover bias parameter. The actual situation of the target area includes information of the neighboring public network base station, a shielding time range and a shielding influence range of the target area, and the like. In order to refine the control target area influence range, power multi-level regulation and control setting can be performed, and the transmitting power corresponding to the target area influence range is set in the shielding control parameters.
In practical application, the interfering base station can open 890-2635 full frequency bands, and integrate at least one of the following network systems in a system integration manner: GSM (Global System for Mobile communications), TD-SCDMA (Time Division-Synchronous Code Division Multiple Access), TD-LTE (Time Division-Long Term Evolution), FDD-LTE (Frequency Division duplex-Long Term Evolution), WCDMA (Wideband Code Division Multiple Access), CDMA2000(Code Division Multiple Access 2000), to support Mobile communication services providing different network formats. Moreover, the interfering base station may also set an MCC (Mobile Country Code) and an MNC (Mobile Network Code) in parallel in advance through the central processing unit, so as to support terminals of different operators in the target area to access the interfering base station simultaneously and in parallel.
The shielding control parameters corresponding to the target area can be respectively set for different network systems. For example, for the GSM system, the shielding control parameters corresponding to the target area may include: CBQ (CELL _ BAR _ quallify, CELL barring limit), CELL reselection bias (CRO, CELL _ reset _ OFFSET), PT (PENALTY _ TIME), frequency bias, CELL bias, and hysteresis bias. For the LTE system, the shielding control parameter corresponding to the target area may specifically include: the method comprises the steps of setting a cell priority parameter with a value of 0-7 based on cell frequency points, CSFB (Circuit Switched Fallback) service bias, redirection bias, neighbor cell bias of a local cell, neighbor cell reselection bias, a tracking area and the like.
Taking GSM as an example, the first priority parameter of the interfering base station may include a first CBQ; the first cell reselection parameter may include: a first cell reselection offset CRO and a first PT; the first cell handover bias parameter may include: a first frequency offset, a first cell offset, and a first hysteresis offset.
Of course, in practical applications, the shielding control parameters may also include parameters commonly used by those skilled in the art, such as a minimum access level, the number of antennas, an identification code, and the like.
The shielding service type corresponding to the target area is a service type which is set according to actual requirements and is required to be shielded by the mobile terminal to be shielded, such as a call service, a short and multimedia message service, a mobile data service and the like.
In practical application, the communication service of the mobile terminal can be distinguished in advance, the type of the communication service which needs to be shielded by the mobile terminal to be shielded in the target area is determined, and the type of the communication service is stored as the shielding service type corresponding to the target area. The shielding service type corresponding to the target area may include one or more communication service types to be shielded. In this way, by setting the type of the masking service, masking of the specified communication service can be realized conveniently, and influence on other communication services can be avoided. For example, school prohibits students from accessing internet, but needs to meet the call requirement, and the set shielding service type includes mobile data service, but does not include call service.
In the embodiment of the present invention, the shielding control parameter and the shielding service type corresponding to the target area may be stored in advance in the interfering base station or in another device connected to the interfering base station. Accordingly, after the interference base station judges that the target area meets the shielding trigger condition, the shielding control parameter and the shielding service type corresponding to the target area can be searched locally or obtained from other equipment.
Preferably, in the embodiment of the present invention, the shielding control parameter may further include: the masking duration. The shielding time length is used for controlling the shielding control time length of the mobile terminal in the target area.
S120: and the interference base station replaces the initial control parameter in the broadcast message with the shielding control parameter and sends the broadcast message to the mobile terminal in the target area, so that the mobile terminal in the target area preferentially selects the interference base station to establish communication connection.
The interference base station is configured with initial control parameters in the broadcast message, and is used for being compatible with the functions of the public network base station and providing normal mobile communication service for the mobile terminal in the coverage area.
In this step, in order to implement mobile terminal shielding, the shielding control parameter corresponding to the target area obtained in step S110 may replace the initial control parameter originally configured in the broadcast message, and then the broadcast message containing the shielding control parameter is sent to the mobile terminal in the target area.
In order to avoid establishing communication connection between a mobile terminal to be shielded and a neighboring public network base station of an interfering base station, in the embodiment of the present invention, the mobile terminal in a target area is forcibly absorbed, so that the mobile terminal preferentially selects to establish communication connection with the interfering base station, that is, the mobile terminal in the target area can preferentially select a cell of the interfering base station as a resident cell in cell selection, reselection and handover processes.
In the embodiment of the present invention, in order to distinguish cell parameters of an interfering base station from cell parameters of neighboring public network base stations around the interfering base station, each cell parameter of the neighboring public network base stations may be respectively referred to as: a second maximum transmit power, a second priority parameter, a second cell reselection parameter, and a second cell handover bias parameter. Taking GSM as an example, the second priority parameter of the neighboring public network cell may include a second CBQ, and a value of the second CBQ may be 0 or 1; the second cell reselection parameters may include: a second cell reselection bias and a second PT; the second cell handover bias parameter may include: a second frequency offset, a second cell offset, and a second hysteresis offset.
The neighboring public network base stations around the interfering base station may be one or more, and the same type of cell parameters of different neighboring public network base stations may be further distinguished by other means commonly used in the art. For example, the second maximum transmit power of neighboring public network base stations a and B may be written as: a second maximum transmit power PWR2A, a second maximum transmit power PWR 2B.
In the embodiment of the invention, the forced absorption of the mobile terminal in the target area can be realized by setting the shielding control parameter. Specifically, the shielding control parameter may be set based on a condition required to complete forced absorption in three states when the mobile terminal establishes connection with the base station.
State one, cell selection
When considering cell selection by a mobile terminal, a cell with a high maximum transmission power and a higher priority is selected. Therefore, in the embodiment of the present invention, the first maximum transmission power in the shielding control parameter is greater than the second maximum transmission power of the neighboring public network base station of the interfering base station; the cell priority characterized by the first priority parameter is higher than or equal to the cell priority characterized by the second priority parameter of the neighboring public network base station.
In practical application, for example, GSM is taken as an example, the first priority parameter of the interfering base station and the second priority parameter of the public network base station can both be represented by CBQ. The CBQ is used for setting the priority level of a cell, and the priority level is divided into high (high priority level) and low (low priority level); CBQ is 0(high), normal, high priority; and CBQ is 1(low) with low priority. In the embodiment of the present invention, in order to ensure that the cell priority represented by the first priority parameter is higher than or equal to the cell priority represented by the second priority parameter of the neighboring public network base station, the first CBQ in the first priority parameter of the interfering base station may be directly set to 0 (high).
Further, the CBA (CELL _ BAR _ ACCESS _ SWITCH) is used to set whether the CELL is forbidden to ACCESS, which is divided into YES (forbidden ACCESS) and NO (allowed ACCESS). When CBA is 0(NO), it indicates that access is not prohibited, i.e., allowed; when CBA is 1(YES), access is prohibited. In view that the value of the CBA will affect the effectiveness of the value of the CBQ, in this embodiment of the present invention, the first priority parameter of the interfering base station may further include the first CBA, and the values of the first CBQ and the first CBA of the interfering base station are set to 00, which ensures that the cell priority represented by the first priority parameter is in a normal state, i.e., a high priority state, during cell selection or reselection.
Therefore, after the interference base station sends the broadcast message containing the shielding control parameter to the mobile terminal in the target area, if the mobile terminal is in a power-off state or a power-on unconnected state, when the mobile terminal is powered on to be ready to establish connection with the base station, the mobile terminal can perform cell selection according to the received broadcast message of the interference base station and the broadcast message of the adjacent public network base station, and then preferentially select the interference base station with higher maximum transmission power and higher cell priority to establish communication connection, so that forced absorption of the interference base station to the mobile terminal in the target area during cell selection is realized.
State two, cell reselection
Considering that the value of the cell reselection channel quality standard parameter C2 of a certain cell exceeds the C2 value of the current serving cell of the mobile terminal for 5 seconds continuously, the mobile terminal will perform cell reselection. Therefore, in the embodiment of the present invention, the cell reselection channel quality standard parameter characterized by the first cell reselection parameter is greater than the cell reselection channel quality standard parameter characterized by the second cell reselection parameter of the neighboring public network base station.
Taking GSM as an example, the value of C2 is related to PT and cell reselection bias, and when PT is not equal to 640 seconds, the larger the cell reselection bias is, the larger the value of C2 is. Therefore, in order to ensure that the value of C2 of the interfering base station exceeds the value of C2 of the current serving cell, the first compensation time PT in the first cell reselection parameter is not equal to 640 seconds, and the first cell reselection bias is greater than the second cell reselection bias of the neighboring public network base station.
Thus, when a plurality of interference base stations send broadcast messages containing shielding control parameters to the mobile terminal in the target area, the mobile terminal already establishes communication connection with the adjacent public network base station and does not perform any service, then the mobile terminal determines that the C2 value of the interference base station exceeds the C2 value of the current service cell of the mobile terminal for 5 seconds continuously according to the received broadcast messages of the interference base station, the broadcast messages of the adjacent public network base station and the C2 of the current service adjacent public network base station, and then triggers cell reselection, and preferentially selects the interference base station to establish communication connection, so as to realize forced absorption when the interference base station performs cell reselection on the mobile terminal in the target area.
In practical application, when the first priority parameter of the interfering base station is a cell priority parameter which is set in advance based on cell frequency points and takes a value of 0-7, the parameter defines the priority of service frequency reselection in a pilot frequency cell and takes a value between 0 and 7, wherein 0 represents the lowest priority. Therefore, in the embodiment of the present invention, the cell priority parameter of the interfering base station may be directly set to 7, so as to further improve the chance of selecting the interfering base station during cell reselection.
State three, cell handover
When the cell quality of the adjacent cell calculated by the mobile terminal is higher than the preset handover threshold, cell handover is triggered. Therefore, in the embodiment of the present invention, the quality of the cell represented by the first cell handover offset parameter in the shielding control parameter corresponding to the target area is higher than the preset absolute threshold for handover.
Taking GSM as an example, the cell quality is mainly characterized by frequency offset, cell offset and hysteresis offset, and the larger the frequency offset and cell offset are, the smaller the hysteresis offset is, the higher the characterized cell quality is. Therefore, to ensure that the quality of the cell characterized by the first cell handover offset parameter is above a predetermined absolute threshold for handover, a first frequency offset in the first cell handover offset parameter of the interfering base station is higher than a second frequency offset in a second cell handover offset parameter of the neighboring public network base station, the first cell offset is higher than the second cell offset, and the first hysteresis offset is lower than the second hysteresis offset.
Therefore, when a plurality of interference base stations send broadcast messages containing shielding control parameters to mobile terminals in a target area, the mobile terminals already establish communication connection with adjacent public network base stations and perform communication service, then, when the mobile terminals determine that the cell quality of the adjacent interference base stations of the current service cell is higher than a preset switching absolute threshold according to the received broadcast messages of the interference base stations and the broadcast messages of the adjacent public network base stations, cell switching is triggered, the mobile terminals preferentially take the interference base stations as target switching objects to establish communication connection, and forced absorption of the interference base stations to the mobile terminals in the target area during cell switching is realized.
S130: and if an access request sent by the mobile terminal according to the shielding control parameter is received, responding to the access request corresponding to the mobile terminal in the white list of the shielding terminal according to a preset white list of the shielding terminal, and shielding the mobile terminal according to the type of the shielding service after the communication connection is established.
In the embodiment of the invention, after the mobile terminal in the target area receives the broadcast message of the interference base station and preferentially selects the interference base station to establish communication connection, an access request is sent to the interference base station so as to access the wireless network of the interference base station.
In order to avoid communication interference to the mobile terminal which does not need to be shielded, the interfering base station may perform targeted processing of the mobile terminal to be shielded. Specifically, after receiving an access request sent by the mobile terminal according to the shielding control parameter, the interfering base station may obtain a preset white list of the shielding terminal through the central processing unit; the white list of the shielded terminal comprises the mobile terminal to be shielded. Then, aiming at the mobile terminal to be shielded in the white list of the shielding terminal, the interference base station responds to the access request corresponding to the mobile terminal and establishes the communication connection between the interference base station and the mobile terminal.
After establishing the communication connection, the interfering base station may perform shielding processing on the mobile terminal according to the shielding service type corresponding to the target area acquired in step S110. For example, when the mobile terminal initiates a communication service, the type of the communication service may be matched with the type of the shielding service, and if the matching is successful, the interfering base station performs shielding processing on the communication service.
Preferably, in the embodiment of the present invention, after receiving an access request sent by a mobile terminal according to a shielding control parameter, the number of users can be monitored in real time, and the number of mobile terminals that have established communication connection with the interfering base station can be monitored in real time; and if the number of the mobile terminals which have established communication connection with the interference base station is monitored to exceed the preset maximum number of the access terminals, rejecting the currently received access request.
As can be seen from the above description, in the embodiment of the present invention, for the problem of communication interference of a mobile terminal that does not need to be shielded in the existing shielding scheme, it is proposed to force the mobile terminal in the target area to preferentially select the base station to establish a communication connection and block the connection between the mobile terminal to be shielded and the public network base station by shielding the control parameter and the shielding service type; and then, distinguishing the mobile terminal to be shielded and the mobile terminal which does not need to be shielded according to the white list of the shielding terminal, and carrying out targeted service shielding processing on the mobile terminal to be shielded which is absorbed forcibly, so that the shielding of the mobile terminal to be shielded is realized, and meanwhile, the communication interference caused to the mobile terminal which does not need to be shielded is avoided.
Preferably, for the mobile terminal that does not need to be shielded, the interfering base station may preset a white list of the serving terminal, so as to further ensure normal communication of the mobile terminal that does not need to be shielded.
In particular, referring to fig. 2, there is shown an exemplary flowchart of a mobile terminal shielding method according to a second embodiment of the present invention.
As shown in fig. 2, a mobile terminal shielding method according to a second embodiment of the present invention may include the following steps:
s210: and if the interference base station judges that the shielding triggering condition is met, acquiring a shielding control parameter and a shielding service type corresponding to the target area.
S220: and the interference base station replaces the initial control parameter in the broadcast message with the shielding control parameter and sends the broadcast message to the mobile terminal in the target area, so that the mobile terminal in the target area preferentially selects the interference base station to establish communication connection.
S230: and if an access request sent by the mobile terminal according to the shielding control parameter is received, responding to the access request corresponding to the mobile terminal in the white list of the shielding terminal according to a preset white list of the shielding terminal, and shielding the mobile terminal according to the type of the shielding service after the communication connection is established.
Steps S210, S220, and S230 in the mobile terminal shielding method provided in the embodiment shown in fig. 2 may refer to specific implementations of steps S110, S120, and S130 in the mobile terminal shielding method provided in the embodiment shown in fig. 1, and are not described herein again.
S240: and if an access request sent by the mobile terminal according to the shielding control parameter is received, responding to the access request corresponding to the mobile terminal in the white list of the service terminal according to a preset white list of the service terminal, and providing mobile communication service for the mobile terminal after communication connection is established.
The mobile terminal in the white list of the service terminal is specifically a mobile terminal that does not need shielding.
Therefore, through a preset white list of the service terminal, the interference base station can screen out mobile terminals which do not need shielding in the mobile terminals sending the access request; for a mobile terminal which does not need shielding, an interference base station can establish communication connection between the interference base station and the mobile terminal based on an access request sent by the mobile terminal, and provide mobile communication service for the mobile terminal, thereby avoiding communication interference caused to the mobile terminal which does not need shielding when shielding processing is carried out on the mobile terminal which needs shielding.
Optionally, for the mobile terminal that does not need to be shielded, the interfering base station may preset a service terminal blacklist for further ensuring normal communication of the mobile terminal that does not need to be shielded.
In particular, referring to fig. 3, there is shown an exemplary flowchart of a mobile terminal shielding method according to a third embodiment of the present invention.
As shown in fig. 3, a mobile terminal shielding method according to a third embodiment of the present invention may include the following steps:
s310: and if the interference base station judges that the shielding triggering condition is met, acquiring a shielding control parameter and a shielding service type corresponding to the target area.
S320: and the interference base station replaces the initial control parameter in the broadcast message with the shielding control parameter and sends the broadcast message to the mobile terminal in the target area, so that the mobile terminal in the target area preferentially selects the interference base station to establish communication connection.
S330: and if an access request sent by the mobile terminal according to the shielding control parameter is received, responding to the access request corresponding to the mobile terminal in the white list of the shielding terminal according to a preset white list of the shielding terminal, and shielding the mobile terminal according to the type of the shielding service after the communication connection is established.
Steps S310, S320, and S330 in the mobile terminal shielding method provided in the embodiment shown in fig. 3 may refer to specific implementations of steps S110, S120, and S130 in the mobile terminal shielding method provided in the embodiment shown in fig. 1, and are not described herein again.
S340: and if an access request sent by the mobile terminal according to the shielding control parameter is received, rejecting the access request corresponding to the mobile terminal in the blacklist of the service terminal according to a preset blacklist of the service terminal so that the mobile terminal selects an adjacent public network base station of the interference base station to establish communication connection.
The mobile terminal in the service terminal blacklist is specifically a mobile terminal that does not need to be shielded. Through a preset service terminal blacklist, the interference base station can screen out mobile terminals which do not need shielding in the mobile terminals sending the access requests; for a mobile terminal which does not need shielding, an interference base station refuses to respond to an access request sent by the mobile terminal so as to refuse to establish communication connection with the mobile terminal; therefore, the mobile terminal refused to connect can reselect the cell capable of establishing communication connection from the adjacent public network base station to provide mobile communication service for the mobile terminal, and communication interference caused to the mobile terminal without shielding when shielding processing is carried out on the mobile to be shielded is avoided.
More preferably, the masking state considering the target region may be divided into a masking period and a non-masking period.
In order to more effectively use the interference base station, the interference base station can select the function of being compatible with the public network base station under the condition that the shielding triggering condition is not met, and mobile communication service is provided for the mobile terminal in the coverage range. Specifically, if the interfering base station determines that the shielding trigger condition is not satisfied, the interfering base station may send a broadcast message containing an initial control parameter to the mobile terminal in the target area, so as to provide a normal mobile communication service for the mobile terminal in the target area together with the neighboring public network base station.
Or, more preferably, if it is determined that the shielding trigger condition is not satisfied, under the condition that the interfering base station is compatible with the function of the public network base station, the mobile communication network signal transmitted by the interfering base station is distributed in the target area through a preset signal distribution system, so as to enhance the signal coverage of the target area during the non-shielding period and improve the terminal capacity of the area.
For example, an existing indoor distribution system may be coupled to serve as a signal source of the indoor distribution system, and a mobile communication network signal transmitted by an interfering base station is distributed in a target area by a signal distribution system in the indoor distribution system. Or, a distributed system form or a pull-out outdoor antenna coverage mode can be newly established, and the mobile communication network signals transmitted by the interference base station are distributed in the target area.
In practical application, when judging that the shielding trigger condition is met, if a mobile terminal which establishes communication connection with the interference base station exists in a target area, the interference base station can disconnect the communication connection between all the connected mobile terminals; or, according to the white list of the shielding terminal, the communication connection between the mobile terminal and the mobile terminal to be shielded is reserved, and then the shielding processing is carried out on the mobile terminal to be shielded according to the shielding service type.
