Abstract
The invention discloses a location updating mechanism-based WCDMA communication shielding gating method. The method includes the following steps that: virtual cellular cell information is wirelessly broadcasted through a WCDMA base station; when a WCDMA mobile terminal in an effective coverage range monitors signals of a virtual cellular cell, and the signals satisfy cell switching conditions or cell signal re-selection conditions, the WCDMA mobile terminal is switched to the virtual cellular cell from an originally-resident operator cellular cell, and parses the location area identifier of the virtual cellular cell; the WCDMA mobile terminal initiates a location updating request in the virtual cellular cell; and the virtual cellular cell makes different responses to the location updating request according to an IMSI number list, so that control on communication shielding gating of the WCDMA mobile terminal can be realized. With the method adopted, efficient communication shielding can be realized, and users can be accurately distinguished, and accurate shielding or gating can be realized.
Description
Technical field
The present invention relates to a kind of WCDMA communication shielding gating method of position-based update mechanism.
Background technology
In the applications such as anti-terrorism stability maintenance, security protection, for security needs, sometimes need to carry out control to region WCDMA mobile communication.Mostly technological means is in the past that the mode adopting electromagnetic signal to suppress realizes the interference to mobile communication signal, reaches the object of shielded communication.This mode shortcoming is: first, communication screening effectiveness is low, when the WCDMA signal for strong anti-interference performance is suppressed, very large transmitting power cost (interfering signal power exceeds 26dB than normal communications signal) be paid, just can reach the effect of shielding; The second, cannot realize the accurate control of WCDMA mobile communication, under special occasions, need to implement accurate shielding or gating to the user specified, electromagnetic signal compacting cannot meet the demands.
Summary of the invention
In order to overcome the above-mentioned shortcoming of prior art, the invention provides a kind of WCDMA communication shielding gating method of position-based update mechanism, solve WCDMA high-effect communication shielding and accurate control problem, pass through the method: the first, high-effect communication shielding (communication shielding can be realized when jam-to-signal signal of communication exceeds 4 ~ 6dB) can be realized; The second, by the utilization to position update mechanism, accurately can distinguish user, realize accurate shielding or gating.
The technical solution adopted for the present invention to solve the technical problems is: a kind of WCDMA communication shielding gating method of position-based update mechanism, and particular content is as follows:
One, by WCDMA base station radio broadcasting virtual Cell Info;
Two, the WCDMA mobile terminal in effective coverage range monitors the signal of virtual cellular community, and signal conditioning is when meeting cell merge or cell re-selection conditions, WCDMA mobile terminal to virtual cellular cell merge, and resolves the Location Area Identification of virtual cellular community by former resident operator cellular cell;
Three, WCDMA mobile terminal initiates " position updating request " in virtual cellular community;
Four, virtual cellular community makes to " position updating request " control that different responses realizes shielding WCDMA communication of mobile terminal gating according to IMSI number list.
Compared with prior art, good effect of the present invention is:
1, utilize cell merge and cell re-selection mechanism, by rationally arranging the transmitting power of virtual cellular community, making WCDMA terminal perform cell merge or gravity treatment, realizing the absorption to WCDMA terminal.Because the threshold value of cell merge or cell reselection is lower, so virtual subdistrict signal only need exceed 4 ~ 6dB than normal communications signal;
2, utilize location updating mechanism, based on communication gating shielding list (IMSI number list), realize shielding accurately or gating mobile terminal.After WCDMA mobile terminal is switched to virtual subdistrict (cellular cell that implementer is gone out by WCDMA base station broadcast) by former resident operator's cellular cell switching or gravity treatment, because the Location Area Identification of virtual subdistrict is different from the Location Area Identification of the former persistent district of WCDMA mobile terminal, WCDMA mobile terminal will in virtual subdistrict launch position update request.Virtual subdistrict receives " position updating request " message that WCDMA mobile terminal is initiated, according to gating shielding list, different responses is made to realize the control to WCDMA communication of mobile terminal shielding gating to different user terminals: first, virtual subdistrict response " location updating refusal " message, WCDMA mobile terminal is according to location updating mechanism, being switched to can the abutting subdistrict (operator provide can the community of proper communication) of successful implementation location updating, can proper communication; The second, virtual subdistrict response " location updating acceptance " message, WCDMA mobile terminal then resides in virtual subdistrict, and virtual subdistrict shields the WCDMA mobile terminal resided within the scope of it.
Accompanying drawing explanation
Examples of the present invention will be described by way of reference to the accompanying drawings, wherein:
Fig. 1 is flow chart of the present invention.
Embodiment
A WCDMA communication shielding gating method for position-based update mechanism, as shown in Figure 1, particular content is as follows:
One, by WCDMA base station radio broadcasting virtual Cell Info:
By WCDMA base station radio air cellular cell information, " virtual " goes out a new cellular cell, and arranges the lane place (different from the lane place of adjacent cell) belonging to this virtual subdistrict.Virtual cellular cell information comprises: frequency, cell scrambling, transmitting power, lane place coding etc.
Two, the WCDMA mobile terminal in effective coverage range monitors the signal of virtual cellular community, and signal conditioning is when meeting cell merge or cell re-selection conditions, WCDMA mobile terminal to virtual cellular cell merge, and resolves the Location Area Identification of virtual cellular community by former resident operator cellular cell.
Three, WCDMA mobile terminal initiates " position updating request " in virtual cellular community:
Because the Location Area Identification of virtual cellular community is different from the Location Area Identification of the former persistent district of WCDMA mobile terminal, WCDMA mobile terminal will initiate " position updating request " in virtual cellular community.
Four, virtual cellular community makes different responses according to communication gating shielding list (IMSI number list) to " position updating request ":
When virtual cellular community receives " position updating request " message of WCDMA mobile terminal initiation, realize the control to WCDMA communication of mobile terminal shielding gating by different responses:
(1) when WCDMA mobile terminal is when belonging in IMSI number list the mobile phone users needing to shield, virtual cellular community response " location updating acceptance " message, WCDMA mobile terminal then resides in virtual cellular community, and virtual cellular community shields the WCDMA mobile terminal resided within the scope of it;
(2) when WCDMA mobile terminal is when belonging to the mobile phone users needing gating in IMSI number list, virtual cellular community response " location updating refusal " message, WCDMA mobile terminal is according to location updating mechanism, being switched to can the abutting subdistrict (operator provide can the community of proper communication) of successful implementation location updating, carries out proper communication.
