The method has the advantages that any modification to MSC side is not needed; alteration to BSC side is not much; the realization is simple; through an enforcement of the ordered registration request to lead the illegal terminal to initiate a position updating, after judging the terminal to be illegal by the network according to a valid identification parameter carried by the illegal terminal, the identification parameter is validly positioned to the illegal terminal and a locking order is sent out to the illegal terminal, thus locking the illegal terminal and reducing interruption to the legal terminal.
Description
Technical field
The present invention relates to field of mobile communication, particularly a kind of method that prevents illegal terminal interfering legality terminal.
Background technology
In mobile communication network, some illegal terminals often appear, and they have duplicated international mobile subscriber identity (IMSI) information of real user terminal, have only Electronic Serial Number (ESN) inconsistent, attempt to insert and usurp Internet resources in the wireless network.Present wireless network all has a cover security mechanism separately, can prevent fully that this illegal terminal from utilizing Internet resources to initiate every business, but in some cases, the existence of this illegal terminal still can interfere with the business of normal users and use, and validated user is caused certain puzzlement.For example, in the CDMA communication network, base station calling comes paging called by IMSI, when legal terminal and the illegal terminal of ESN are in the paged scope simultaneously, in case illegal terminal has responded the beep-page message of base station earlier, thereby the chance that will cause legal terminal to lose access is eventually exhaled failure, is illustrated in figure 1 as illegal terminal and legal terminal in same base station (BSC) following time, and illegal terminal is to exhaling disturbed condition the end of legal terminal:
Step 101: mobile switching centre (MSC) sends the paging request to BSC, requires certain user is carried out paging;
Step 102-step 103:BSC broadcast paging messages;
Step 104: illegal terminal has at first responded the paging request;
Step 105:BSC returns page-response message to MSC;
Step 106:MSC judges that the user is illegal, sends clear command to BSC;
Step 107:BSC issues clear command to illegal terminal;
Step 108: validated user response paging request, directly refused by BSC.
For legal terminal and illegal terminal respectively under different BSC, and these two BSC of MSC have issued the situation of paging request simultaneously, if same illegal terminal has responded the paging request earlier,, also can be refused by MSC even the BSC at legal terminal place has returned page response to MSC so.
The registration of receiving a mandate that normal MSC initiates, if illegal terminal has at first responded, flow chart as shown in Figure 2:
Step 201:MSC sends the registration request of receiving a mandate that contains targeted customer IMSI to BSC;
Step 202:BSC all users in the request scope send Registration Request Order (registration request) message;
Step 203: if return Registration Message (registration message) response message to BSC after illegal terminal in this receives a mandate the specified scope of registration, is received Registration Request order message;
Step 204: the base station is assembled a location update request message and is sent to MSC after receiving the Registration Message message that terminal is responded;
After step 205:MSC receives this location update request message, judge this terminal illegal (for example the ESN of ESN and validated user does not match), put the renewal refuse information for the BSC return, Reason For Denial is 3 (illegal terminals);
Step 207:BSC receives position renewal refuse information, sends the instruction of registration refusal to illegal terminal.
Summary of the invention
In order to solve above-mentioned technical problem, a kind of method that prevents illegal terminal interfering legality terminal is provided, and its purpose is, when having caused certain interference when certain illegal ESN terminal existence of discovery and to validated user, can find it and it is pinned terminal, make it no longer enter access state.
The invention provides a kind of method that prevents illegal terminal interfering legality terminal, may further comprise the steps:

Step 2, described base station all users in the request scope send register request message, carry described international mobile subscriber identity information;
Step 3, if the user of illegal terminal receives a mandate at this and registers in the specified scope, can return the registration message response message after receiving described register request message, for described base station, comprise the data parameters that to discern described illegal terminal in the described registration message response message;
Further comprising the steps of:
Step 4 confirms that described illegal terminal is illegal, and described illegal terminal transmission order, is used to pin described illegal terminal;
Described step 4 may further comprise the steps:
Step 5, described base station is after receiving described registration message response message, write down the described effectively data parameters of identification of illegal terminal, assemble a location update request message and send to described mobile switching centre, described location update request message comprises the data parameters of described effectively identification of illegal terminal and the international mobile subscriber identity of described illegal terminal;
Step 6, after this location update request message was received by described mobile switching centre, the terminal of judging described user was an illegal terminal, upgraded refuse information for described base station home position, Reason For Denial is illegal terminal for this terminal;
Step 7, described base station, sends order to described illegal terminal and pins described illegal terminal as the addressing parameter according to the international mobile subscriber identity of the data parameters of the effectively identification of illegal terminal of described record and described illegal terminal;
Step 8, described base station sends the order of registration refusal to described illegal terminal.
The described data parameters that can discern described illegal terminal is the Electronic Serial Number of described illegal terminal.
In the described step 5, if the described effectively data parameters of identification of illegal terminal is not write down in described base station, then by the interface between described mobile switching centre of expansion and the described base station, the described position in described step 6 is upgraded in the refuse information and is sent to described base station.
In the described step 7, the order that sends to described illegal terminal is that locking terminal is up to next machine open/close order.
This method need not the MSC side and makes any modification, and the change that the BSC side is done is also little, realizes simple.Forcing to allow illegal terminal initiate the position by the registration message of receiving a mandate upgrades, effective identification parameter that network based illegal terminal carries judge terminal illegal after, effectively navigate to illegal terminal and to its transmission order of locking with this identification parameter, thereby the pinning illegal terminal reduces its interference to legal terminal.
