Description
Technical field
The present invention relates to the communication technology, particularly a kind of connection control method and device based on IMEI.
Background technology
In the coverage of middle mobile existing network, have indivedual regions in border belt (as, between two countries border, separated by hundreds of rice to the wide waters of km), there is the situation of transboundary covering in domestic TD SDMA (Time Division Synchronized Code Division Multiple Access, TD-SCDMA) signal.
In practical application, conventionally cause for a certain reason part TD terminal to be wandered overseas, and this part the TD terminal being in overseas can be carried out the business such as voice, data, note by access TD-SCDMA network, make a nation's security have certain hidden danger.
For the problems referred to above, two kinds of solutions in prior art, are provided.
The first solution is: the angle of optimizing from the network planning is considered.
By adjust the antenna feeder, domestic ground of high station community mend blind, set up lamp stand station etc. mode, macrocellular is split into a succession of cellulor, to realize accurately Coverage Control.
But, but this scheme is to existing network transformation is large, cost of investment is higher.
The second solution is: solve from the angle of algorithm optimization.
Be network side based on terminal position, judge that whether terminal is in He Fei exclusion area, exclusion area, with the object to control terminal access.
This scheme is without making change to existing network, and cost of investment is little, only by software upgrading, simple.
Current existing algorithm arrangement is: based on azimuth (Arrival Of Angle, AOA)+Timing Advance (Timing Advanced, TA), user is overseas carried out to access control and traffic limits.
The party's ratio juris is: radio network controller (Radio Network Controller, RNC) at terminal (User Equipment, UE) Radio Resource control (Radio Resource Control, RRC) after having set up, the position of inquiry UE, if within UE position is positioned at prohibited area, the RRC that discharges UE connects (sending RRC release message to UE).
Wherein, consult shown in Fig. 1 and Fig. 2, the computational methods of terminal location are:
The TA that RNC reports in Uu measurement report (Uu interface is the communication interface between UE and base station) according to UE, determines the distance of UE to base station.
The RNC AOA that (Iub interface is the communication interface between base station and RNC) reports in Iub measurement report according to base station, determines the azimuth of UE.
If the azimuth of UE within limits and UE to the distance of base station be more than or equal to set thresholding (the distance threshold difference that different azimuths is corresponding), think that UE is in prohibited area, now RNC discharges the resource of UE, as, initiating Iu(Iu interface is the communication interface between RNC and core net) discharge, initiate RRC Connection Release).
Based on the algorithm arrangement of AOA+TA, in implementation process, TA measured value and the actual range deviation of finding part terminal to report are larger, and the TA measured value of the terminal to report that the TA measured value of some terminal to report is less than normal, have is bigger than normal, makes the existing use of the control program based on AOA+TA limited.
For example, under prior art, the distance transform of TA measured value and base station closes and is: distance=TA measured value * 14.7 of reporting:
Certain A brand terminal, reports TA value bigger than normal, as, 150 meters, UE actual range antenna, but the TA measured value that TA reports is 140, its respective distances is 2058 meters.
Certain B brand terminal, reports TA measured value bigger than normal, as, 550 meters, UE actual range antenna, but the TA measured value that TA reports is 167, its respective distances is 2455 meters.
Certain C brand terminal, reports TA measured value less than normal, as, 150 meters, UE actual range antenna, but the TA measured value that TA reports is 8, its respective distances is 117 meters.
Can find out from foregoing description, for control area overseas, less than normal if the TA measured value of terminal to report is compared actual range, this terminal can be at region call establishment overseas, thereby affects RNC to the calling control of control area overseas.
For territory, domestic noncontrolled area, bigger than normal if the TA measured value of terminal to report is compared actual range, this terminal also may because of erroneous judgement, cause cannot call establishment in territory, noncontrolled area, thereby affects user awareness.
In view of this, need to solve as early as possible the demand of Coverage Control overseas of TD-SCDMA signal, the TD terminal of controlling overseas accesses and commences business in China TD-SCDMA system.

Embodiment
In order to implement exactly domestic access control overseas, the embodiment of the present invention, RNC can be according to the International Mobile Station Equipment Identification of terminal (International Mobile Equipment Identities, IMEI) longitude and latitude of information and terminal and range information, judge that whether the position at terminal place is in prohibited area, to be implemented to the restriction to customer service, meet consumers' demand.
Below in conjunction with accompanying drawing, the preferred embodiment of the present invention is elaborated.
In the embodiment of the present invention, the deficiency based on existing scheme is improved, and adopts the method for IMEI+AOA+TA to carry out access control to UE.In order to realize this access control mode, pretreatment stage, RNC need to carry out magnanimity test to all kinds of UE, thereby determine UE under different application scene (as, diverse geographic location, different brands etc.) TA error amount, and building database being updated in configuration data, at least comprises the corresponding relation between IMEI information and the TA error amount of UE in this database.Like this, just on the basis of existing " AOA+TA ", IMEI information by identification UE, revise according to corresponding TA error amount the TA measured value that UE reports, and carry out judgement and the access control of UE position based on revised TA measured value.
Consult shown in Fig. 3, in the embodiment of the present invention, the general introduction flow process that RNC carries out access control based on IMEI information to UE is as follows:
Step 300:RNC receives the TA measured value that UE reports, and carries out IMEI inquiry for UE, and receives the IMEI information of UE feedback.
Concrete:
RNC first sets up RRC with UE and is connected, and after RRC connection has been set up, obtains the TA measured value that UE reports;
The IMEI information of UE needs RNC to pass through IMEI query function (IMEI CHECK) to obtain, and obtaining of IMEI information requires RNC to open IMEI CHECK query function.RNC is generally with after core net is set up Iu and is connected, and analog core net sends UE Identity Req and obtain the IMEI information of UE to above-mentioned UE; IMEI information is used for unique identification UE, and can distinguish the brand of UE.
On the other hand, in the embodiment of the present invention, RNC, in order to carry out error information processing, needs the interface of the TA error based on IMEI in internal configurations in advance, like this, carries out access control thereby administrative staff may enter error adjustment interface by man-machine interface.
Step 310:RNC determines the TA error amount that the IMEI information of corresponding UE is default, and adopts this TA error amount to revise the TA measured value of UE.
Be specially: RNC first determines the default TA error amount of IMEI information of corresponding UE, then determine the default error adjustment mode of IMEI information of corresponding UE, then, RNC adopts this error to adjust mode and TA error amount is adjusted the TA measured value of UE.
In practical application, in the IMEI of RNC information table, dispose the IMEI information of each UE and the corresponding relation of TA error amount, and dispose the corresponding relation of IMEI information and the error adjustment mode of each UE.Concrete: in the IMEI of RNC information table, dispose " TA error adjustment mark " (being that error is adjusted mode), span 0～1,0 represents that TA is bigger than normal, and 1 represents that TA is less than normal, and disposes " TA correcting offset " (being TA error amount), if TA is bigger than normal, while calibration, can on the basis of the TA measured value reporting, deduct TA error amount, if TA is less than normal, while calibration, can on the TA value of the reporting basis reporting, increase skew.
Step 320:RNC carries out access control based on revised TA measured value to UE.
Concrete, RNC determines according to the measurement report of base station the AOA that the current location of UE belongs to, whether the AOA based on obtaining and the revised TA measured value of UE judge that UE is current and are positioned in prohibited area again, if, forbid that the radio resource control RRC between described UE access release and described UE is connected, otherwise, allow described UE access and carry out access control for described UE.
In practical application, the TA threshold value difference that different AOA is corresponding, the AOA that the current location of RNC based on UE belongs to can be known the TA threshold value under this AOA, and whether the revised TA measured value that judges UE reaches this TA threshold value, if, determine that UE is in prohibited area, otherwise, determine that UE is not in prohibited area.
Below in conjunction with a concrete application scenarios, above-described embodiment is made to further description.
Consult shown in Fig. 4, in the embodiment of the present invention, the idiographic flow that RNC carries out access control based on IMEI information to UE is as follows:
Between step 400:RNC and UE, setting up RRC is connected.
Step 410:RNC receives the TA measured value that UE reports.
Step 420:RNC sends IMEI request message to UE.
Step 430:RNC receives the IMEI information of the UE of UE feedback.
Step 440:RNC, according to the IMEI information obtaining, obtain corresponding TE error amount and corresponding error alter mode, and the TA measured value that adopts this error alter mode and TA error amount to report UE is modified.
For example:
" if TA error adjustment mark " for 0(be " bigger than normal "), TA actual value (unit rice)=TA measured value (unit rice)-" TA error deviation "/10.
" if TA error adjustment mark " for 1(be " less than normal "), TA actual value (unit rice)=TA measured value (unit rice)+" TA error deviation "/10.
Replace TA measured value according to the above-mentioned TA correction result calculating (TA actual value), judge that whether UE is in prohibited area.
Does step 450:RNC determine current the be positioned at AOA of UE according to reporting of base station, and within the scope of this AOA, the TA correction value (be revised TA measured value) current according to UE judges that UE is in prohibited area? if so, carry out step 470; Otherwise, carry out step 460.
Step 460:RNC allows UE access network, and UE is carried out to access control.
Step 470:RNC forbids UE access network, and the RRC discharging between UE is connected.
