The present invention achieves the purpose that the lawless user of home base station could be rejected to other valid cell and that the authorized user is impervious by combining the RAU/LAU Reject and the process of relocation.
Description
Technical field
The present invention relates to mobile communication system, the method that particularly in Wideband Code Division Multiple Access (WCDMA) WCDMA/ TD SDMA TD-CDMA/ global system for mobile communications GSM/ third generation 3G system, the residential quarter of UE access is limited.
Background technology
In the UE access network, by Security Function (safety function), UE is carried out authentication. this authentication is mainly for the legitimacy of UE itself, main mutual by core net and HLR (attaching position register), obtain authentication 5 tuples of UE, compare the legitimacy of judgement UE with the information that obtains from UE.
There is at present operator to propose the concept of base station from home Nodeb (HNodeb) or slight Nodeb (femetoNodeb) or HBts, the general designation base station from home, be family small-sized Nodeb is provided, the coverage of this Nodeb is smaller, the carrying user is also little, but property right belongs to the user, and operator can provide rate, and bandwidth etc. are preferential.For this class Nodeb, only allow the individual user to can be accessed by this Nodeb for protecting possessory power, should limiting, other lack of competence user should be rejected.
in present 3G framework, authentication is mainly carried out at CN (core net), under present 3G framework, CN can't be known the cell information at UE place, generally can only adopt RAU/LAU (Routing Area Update/Location Area Update, Routing Area Update/location area updating) mode of refusal is carried out access limitation, but LAC is (Location Area Code, the lane place coding)/RAC (Routing Area Code, Routing Area Code) number the whole network is limited, and base station from home (HNodeb/femetoNodeb/HBts) number is numerous, can't specify LAC for each base station from home, can't directly use the method.
Another kind method is, adopt RRC (Radio Resource Control in RAN (Radio Access Network) side, Radio Resource is controlled) the refusal mode is carried out access limitation, but UE may come up again in the short time in this case, caused ping-pong.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of method that UE access residential quarter is limited, and solves existing residential quarter access limitation method and can't be applied to the Home eNodeB access limitation and maybe may cause the problem of ping-pong.
In order to solve the problems of the technologies described above, the invention provides a kind of method that subscriber equipment access residential quarter is limited, comprise following steps: after the base station connects, be its distribution locations district coding LAC; User equipment (UE) is initiated routing area updating RAU/location area updating LAU request by described base station, and wireless controller judges whether described UE has the access authority of described base station, if do not have, described wireless controller sends the RAU/LAU refuse information to described UE.
Further, said method also can have following characteristics, if described UE does not have the access authority of described base station, described wireless controller judges also whether described UE has and the access authority of this base station with other base stations of LAC, if no, described wireless controller just sends the RAU/LAU refuse information to described UE.

Better embodiment of the present invention
The number of HNodeb is numerous in general, and the LAC number is limited, can not distribute separately a LAC for each base station from home (as HNodeb), therefore must consider the recycling problem of LAC.
This programme considers to adopt the mode of LAU/RAU Reject (LAU/RAU refusal) and relocation (being redirected) combination.Specifically comprise following steps:
1) when HNodeb starts, be its Random assignment LAC, the LAC of different HNodeb can be identical, and namely LAC can duplicate allocation;
Wherein, repeat the probability of LAC in order to reduce adjacent HNodeb, HNodeb for same macrocell distributes different LAC as far as possible, when being HNodeb distribution LAC, at first select the LAC that do not taken by other HNodeb under macrocell, if LAC all under this macrocell are taken by other HNodeb, for its select one minimum occupied be the minimum LAC of occurrence number; If the same LAC of several occurrence numbers is arranged, therefrom choose at random one.
The above-mentioned method of salary distribution can reduce UE and meet the HNodeb that uses with this user with the probability of the HNodeb of LAC.
2) initiate RRC (Radio Resource Control, Radio Resource is controlled) when connecting at UE to HNodeb, allow its RRC to connect and set up;
3) RNC need to be when UE carries out LAU/RAU, the access authority of judgement UE, as long as being UE, judgment principle has the access authority of this HNodeb of access, or and this HNodeb with the access authority of any HNodeb of LAC, allow this UE to carry out normal LAU/RAU process, otherwise RNC send the LAU/RAU refusal with analog core net (CN) to UE;
When running into HNodeb with the HNodeb of LAC, UE can not refused by LAU/RAU, thereby avoid occurring going back home, due to LAI (Location Area Identificaton, Location Area Identification) in the banned list (Forbidden list) of UE, cause this UE can't enter the situation of the HNodeb of authority.
4) when being attached on HNodeb, without the access authority of this HNodeb, but have and this HNodeb when initiating other business with the UE of the access authority of other HNodeb of LAC, utilize the relocation process, UE is switched to macrocell.
For the UE that is attached to lack of competence HNodeb, can be switched to macrocell by RNC in the business of initiation, therefore can not affect the user's of this HNodeb oneself use.
Further describe below by specific embodiment.
After the HNodeb transport layer connected, RNC was this HNodeb and distributes LAC, and as shown in Figure 1, allocation strategy is:
1. search connected and and this HNodeb with the HNodeb of macrocell;
2. select current that connected and this HNodeb there is no the LAC that uses with the HNodeb of macrocell, distribute to this HNodeb;
3. if the current same macrocell HNodeb that has connected has taken all available LAC, check and currently connected and with HNodeb this HNodeb adjacency, whether untapped LAC arranged with macrocell, if have, therefrom choose at random one, distribute to this HNodeb.
4. if the current same macrocell HNodeb that has connected has taken all available LAC, and the HNodeb of this HNodeb adjacency also taken all available LAC, selects a minimum LAC who is used to distribute to HNodeb.
Wherein, the minimum LAC that is used refers to minimum LAC by using with all HNodeb of macrocell, or the minimum LAC that is used by the HNodeb with this HNodeb adjacency, or minimum the use with all HNodeb of macrocell and the minimum LAC that is used by the HNodeb with this HNodeb adjacency.
5. if the minimum LAC that is used has more than one, select at random one.
in another embodiment of the present invention, the HNodeb quantity that macrocell comprises usually is very big, therefore, in the specific implementation, above-mentioned steps 2 can be omitted, namely can not check with all HNodeb under macrocell whether taken all available LAC, whether the HNodeb that only checks the HNodeb adjacency has untapped LAC, if have, select the untapped LAC of HNodeb of an adjacency, distribute to HNodeb, thereby guarantee different the getting final product of its LAC of HNodeb of adjacency, in step 4, if the HNodeb of this HNodeb adjacency has also taken all available LAC, select a minimum LAC who is used to distribute to HNodeb.
Figure 2 shows that unauthorized UE initiates the flow chart of LAU/RAU after distributing LAC for HNodeb, wherein this UE does not also have and accesses HNodeb with the access authority of other HNodeb of LAC.
210, UE initiates ROUTING/LOCATION AREA UPDATE REQUST (routing area/location update request) message;
220, RNC resolves NAS (Non-Access Stratum) layer signaling, obtains this NAS layer information; RNC judges whether UE has the access authority of this HNodeb, if do not have, judges that further whether this UE has other and this HNodeb with the access authority of other HNodeb of LAC, if UE does not all have authority, enters step 230;
230, RNC sends ROUTING/LOCATION ARAE UPDATE REJECT (routing area/location upgrades refusal) message to UE.
Further, in realization, the RAU/LAU refusal can be controlled by CN, also can be controlled by RNC.If controlled by CN, need to revise the Iu mouth.
If controlled by RNC, RNC has following two kinds to realize selecting:
The first: RNC cushions the ROUTING/LOCATION AREA UPDATE REQUST that UE sends, if judge that this UE does not access authority, direct modeling CN sends ROUTING/LOCATION AREA UPDATE REJECT to UE.At CN, it never received the ROUTING/LOCATION AREA UPDATE REQUST request of UE.Only in the situation that UE has authority, RNC just can send to CN with ROUTING/LOCATION AREA UPDATE REQUST.
The second: RNC directly is transmitted to CN with the ROUTING/LOCATION AREA UPDATE REQUST that UE sends, if judge that this UE does not access authority, direct modeling CN sends ROUTING/LOCATION AREA UPDATE REJECT to UE.Other NAS layer message that issue for CN directly abandon.Be equivalent to the RAU/LAU process that due to UE there is no respond the failure that cause at CN this moment.
In step 230, the reason of RAU refusal can be as shown in table 1 below:
Table 1RAU Reason For Denial
Wherein Reason For Denial 15 relatively is fit to the scene of H residential quarter (residential quarter under HNodeb) and the same PLMN of macrocell (Pulic Land Mobile Network, Public Land Mobile Nerwork), but is not suitable for for different PLMN.13 of Reasons For Denial are with can be to the frequency of other PLMN of search under PLMN, and are more suitable for the scene of different PLMN, for the scene of the PLMN electric power of some waste UE.
The reason of LAU refusal can be as shown in table 2:
Different Reasons For Denial can according to different networking situations, be selected by system.
Figure 3 shows that unauthorized UE initiates the flow chart of LAU/RAU, wherein this UE has and accesses HNodeb with the access authority of other HNodeb of LAC.This unauthorized UE is arrived macrocell by relocation when the business of initiation.
310, UE enters HNodeb, carries out the LAU/RAU process.
Although UE does not have the authority of access HNodeb, it has the access authority with other HNodeb of LAC with this HNodeb, so RNC allows its LAU/RAU process.
320, carry out the RRC connection procedure;
330, when UE initiated business, RNC carried out normal access procedure (comprising Access Layer and Non-Access Stratum process);
Table 2LAU Reason For Denial
340, carry out RAB and assign, in carrying out RAB appointment process, this moment is not because this UE has the access authority of this HNodeb, so the RNC judgement should to this UE execution Relocation process referring to Fig. 4, specifically comprise:
S410, CN initiates RAB Assignment Request (RAB assignment request) to RNC;
S420, RNC returns to RAB Assignment Response (RAB assigns response) to CN.
This moment, RNC should indicate unsuccessful RAB configuration modification (failed RAB config update) in the RAB Assignment Response of CN initiation, and indication Cause Value (fail values) is " Relocation triggered " (is redirected and triggers).
Certainly system also can allow after RAB is allocated successfully, then initiates the Relocation process.
350, carry out normal relocation process.
The access limitation of above-described embodiment HNodeb in the 3G system describes enforcement of the present invention as example, the method of submitting a written statement to a higher authority also is applicable in the systems such as WCDMA/TD-CDMA/GSM, RNC is the wireless controller in corresponding system, as base station controller BSC etc., HNodeb also can be base station from home such as HBts or the femetoNodeb etc. of other type.
The present invention has reached the HNodeb unauthorized user and can be denied to other efficient cells, the impregnable purpose of authorized user by RAU/LAU Reject and the combination of relocation process.
Industrial applicibility
UE access of the present invention residential quarter method for limiting has following advantage: 1) to UE, CN, HNodeb all can adopt standard interface without any impact; 2) can reduce UE and meet the HNodeb that uses with this user with the probability of the HNodeb of LAC; 3) when running into HNodeb with the HNodeb of LAC, UE can not refused by LAU/RAU, thereby avoid occurring going back home, due to LAI (Location Area Identificaton, Location Area Identification) in the banned list (Forbidden list) of UE, cause this UE can't enter the situation of the HNodeb of authority; 4) even be attached to the UE of lack of competence HNodeb, also can be switched to macrocell by RNC in the business of initiation, therefore can not affect the user's of this HNodeb oneself use.
