Step 704: described database returns to described CN with the UE that obtains and the CAMEL-Subscription-Information of AP, and CN judges that according to this CAMEL-Subscription-Information obtaining this UE is not allowed to access described AP's;
Step 705:CN informs that AP does not allow current UE to insert; Wherein, in embodiments of the present invention, CN utilizes direct-sending message to inform that AP does not allow UE to insert;
So far, in the embodiment of the invention, the flow process relevant with described control method finishes; In the preferred embodiment of the present invention,, also can further comprise the steps: in order to provide better service to the user
Step 706:AP directly requires UE to carry out blind switching, with other the public private base station that switches to adjacent macro cell or allow this subscriber equipment to insert.Even without of the measurement of this subscriber equipment to peripheral cell, the switching of private base station by taking place in the past, perhaps, also can carry out blind switching on private base station so that private base station triggers subscriber equipment by thereby the information that the equipment of answering is learnt some sub-districts that exist on every side is installed.
In embodiments of the present invention, because AP knows some information of neighbor cell, therefore, do not need UE to measure adjacent macro cell and can carry out blind switching; If not adopting blind switching, then subscriber equipment is switched to the private base station of adjacent macrocell or permission access by normal switching flow.
Step 707:AP initiates to switch, and makes UE switch to adjacent macro cell, wherein, carries out the hand off signaling flow process and the reorientation flow process of described switching, needs AP and CN side gusset mutual;
Step 708:AP notice UE switches to neighbor cell, after described UE receives this notice, switches to described neighbor cell.
In embodiment four, it is the mode that adopts blind switching, by AP UE is switched to adjacent macro cell, in other embodiments of the invention, under the situation that initial UE connects with macrocell, following two kinds of changing methods are also provided, under the situation that does not allow the UE access at current AP, by macrocell UE is switched to other AP, be specially;
Changing method one: in this kind method, described UE is in macrocell, and UE near the AP that allows own access (AP is in macrocell coverage area---in the time of IS), macrocell switches to AP with UE; Here RNC and the NB function with UMTS is incorporated among the AP, so AP will be equal to the Iu interface to the interface of CN (SGSN or MSC).Referring to Fig. 8, this changing method specifically comprises:
Step 800:CN can be in (AP) CAMEL-Subscription-Information of the UE of activated state from the acquisition of CN database---this means the related information (perhaps being the CAMEL-Subscription-Information of the AP adjacent that allows the UE access) of the Iu interfaces need transmission UE～AP of macrocell with macrocell;
Step 801: macrocell send to be measured and to be opened control information to UE, wherein, comprises and tells near information---some wireless parameters configurations of eating dishes without rice or wine of AP that allow the AP that inserts the UE, such as scrambler etc., is convenient to the UE search.
Step 802: macrocell finds that the AP that described permission inserts is a good handover candidate cells, and when confirming to allow UE to insert, sends re-positioning request to CN; Begin the RNC reorientation flow process of UMTS standard thus;
Step 803:CN sends out re-positioning request and gives the described AP of step 802, and in actual applications, this request may need to cross over a plurality of CN nodes, such as a plurality of SGSN etc., here for convenience of description, no longer is described, but is used as a CN node (such as SGSN) operation.At this moment need to transmit some special information, to be different from the general flow of UMTS, this information may be the relevant CAMEL-Subscription-Information of some AP of UE, is used for the inspection of AP to visiting UE, and if not the UE that allows to insert, AP may refuse this handoff procedure.
Step 804: described AP is that UE prepares Radio Resource, after being ready to, sends out re-positioning request and confirms to CN.
Step 805:CN sends out the reorientation order and gives macrocell.
Step 806: macrocell stimulating food reason channel is reshuffled to UE.
Step 807:UE switches to AP, and stimulating food reason channel is reshuffled and finished to AP.
So far UE has finished the switching from the macrocell to AP.It should be noted that: above-mentioned flow process is with the general different place of switching flow, needs the relevant CAMEL-Subscription-Information of using of some UE～AP in these flow processs.Iu interface particularly is the information that the interface of AP～Cn node need transmit to AP.
Changing method two: in the method, allow the UE that inserts to there being privately owned AP, if there is publicly-owned AP in the current macrocell, then macrocell may switch UE and goes to publicly-owned AP; This publicly-owned AP can be certain little supermarket, the pairing AP of office;
At this moment CN can check equally perhaps whether UE is allowed to access this AP, and this AP can check also perhaps whether UE is allowed to access; Even because allow to insert, also may have the difference of priority, if come such as the power user, promptly owner AP has come, and other users may the existence meeting be seized, risk of rejection.So the UE that switches also needs the CAMEL-Subscription-Information of checking that some are relevant with AP.
Referring to Fig. 9, this kind changing method specifically comprises:
Step 900: macrocell is informed near the publicly-owned AP information the UE;
In embodiments of the present invention, macrocell carries out above-mentioned informing by the broadcast message of its macrocell; If the quantity of publicly-owned AP is more, thereby make this broadcast message can't carry the information of all publicly-owned AP, also can only inform the existence of publicly-owned AP, and some essential informations that these publicly-owned AP are common inform UE, and do not inform which publicly-owned AP is specifically arranged by this broadcast message;
Behind information notification UE, make the UE energy measurement arrive the existence of publicly-owned AP with publicly-owned AP;
Step 901: macrocell filters out the publicly-owned AP that allows UE to insert, and sends handover measurement and controls to UE, and UE sends measurement report to macrocell;
Step 902～step 907 is identical with step 802～step 807.
In this changing method two, the access monitoring at publicly-owned AP carries out UE can make that process simplification is many; In addition, consider the advantage that public AP has to be increased covering, reduce the macrocell load, operator can reduce the usage charges of publicly-owned AP, thereby attracts more user to use.
In the foregoing description three and embodiment four, owing to need to judge whether UE is allowed to access AP, therefore, between AP～CN, just on the Iu interface, institute's content transmitted and existing signaling institute content transmitted are different, are specially:
1) AP need check whether allow UE to insert described AP, therefore, need increase the sign of AP in this initial message by aforesaid initial message (Initial UE Message) notice CN, so that CN realizes described inspection according to the sign of this AP.In actual applications, can based on PLMN+LAC (+RAC)+mode of AP identity is a lane place or AP of route district unique identification;

Based on the content in the above-mentioned table 7, can realize whether allowing the UE access and need not CN to participate in by the AP detection.AP preserves some CAMEL-Subscription-Information (such as IMSI, TMSI, P-TMSI etc.) of the UE that allows access.If do not allow the UE that inserts, directly RRC is reoriented to macrocell, specifically comprises:
(1) at first UE sends the RRC connection request to AP;
(2) according to the sign of the UE in the RRC request message (IMSI or TMSI, PTMSI etc.), the UE CAMEL-Subscription-Information of AP by relatively himself preserving, check whether the UE that current request inserts is the UE that allows access, if allow the UE of access, then finishes normal access process.UE if not allowing to insert changes (3) over to;
(3) directly UE is reoriented to adjacent macro cell by RRC, wherein, described reorientation is an existing procedure.
At the preferred embodiment three (1), the control device of corresponding access private base station is provided in the embodiment of the invention, this device can adopt AP to realize that this device comprises:
Receiving element is used to receive the connection request that UE sends;
Judging unit is used for the UE sign (IMSI or TMSI, PTMSI etc.) according to described connection request, and relatively the UE CAMEL-Subscription-Information of this device self preservation checks whether the UE that current request inserts is the UE that allows access;
Notification unit: be used for the judged result of judging unit is notified to UE.
Wherein, in the preferred embodiment of the present invention, the control device of this access private base station also can further comprise the reorientation unit, be used for judgment unit judges obtain UE for the situation that does not allow the UE that inserts under, UE is reoriented to adjacent macro cell.
Whether above control method allows UE to insert at search cycle and AP respectively, below, whether be in the business of not being positioned in conjunction with AP and cover (OOS), be positioned at professional (IS) state that covers, the connection control method during to the access private base station is described in detail:
Embodiment five:
At first, OOS and IS state are introduced respectively:
Referring to scene shown in Figure 10, when AP was positioned at the macrocell Service coverage, then this AP was in the IS state; When AP partly is positioned at the macrocell Service coverage, and part is not when being positioned at the macrocell Service coverage, and this AP is in IS state/oos state; When AP was not positioned at the macrocell Service coverage, this AP was in oos state;
More particularly, in actual applications, exist two kinds of macrocells of UMTS and GSM to cover, accordingly, AP supports UMTS or GSM, or even supports UMTS and two kinds of patterns of GSM simultaneously, at this kind situation, referring to Figure 11 in an embodiment of the present invention, corresponding scene is as follows:
Shown in Figure 11 a, AP is the UMTS pattern, and it is not in the coverage of UMTS and GSM macrocell, and at this moment, this AP is in oos state for these two macrocells;
Shown in Figure 11 b, AP is the UMTS pattern, and it is not in the coverage of UMTS macrocell, but is in the coverage of GSM macrocell, and at this moment, this AP is in oos state for the UMTS macrocell, then is in the IS state for the GSM macrocell;
At above-mentioned scene, referring to Figure 12, in embodiments of the present invention, described connection control method comprises the steps:
Step 1201: judge AP present located state; Wherein, concrete is exactly for judgement AP is in oos state or IS state, or the OOS/IS state; More concrete, can judge the residing state of AP respectively at dissimilar macrocells, for example the situation shown in Figure 11 a and Figure 11 b;
Step 1202:, then be that this AP distributes independent Routing Area Code (LAC) or Routing Area Code (RAC) if judgement obtains the current oos state that is in of AP; Wherein, distribute independent sign, its purpose is to make this AP shared sign of other AP of getting along well, thereby when avoiding appearing at current AP refusal UE and inserting, also refuses UE mistakenly with the AP of the shared sign of this AP and insert; In addition, by distributing independent LAC or RAC for this AP, make and do not allow under the situation of UE access at this AP, be convenient to access with " LA not allowed " reasons such as " ROAMING NOT ALLOWED " refusal UE, at this moment UE can only urgently call on urgently and restricted service such as be, and this can display message see to the user that such as " professional limited; only for urgent ", thereby the prompting user goes to other places to make a phone call.Otherwise, there is not other very suitable reasons refusal UE to insert, why the user can be confused about his UE under the good situation of received signal, can't insert AP.
Step 1203: when UE request inserts AP,,, switch to corresponding sub-district to the limited reason of described UE prompt service or with UE then according to the residing state of this AP self if judge that obtaining this UE is not allowed to access this AP.At the scene shown in Figure 11 b, being implemented as follows of step 1203, wherein, described AP has been assigned with independent RAC:
If UE only supports the UMTS pattern, then do not allow for example to return the information of " LA not allowed " to UE under the situation of UE access, thereby make UE for example can show that " professional limited, only for urgent " such information is to the user at AP;
If UE supports UMTS pattern and GSM pattern, then do not allow under the situation of UE access at AP, AP has two kinds of settling modes:
Mode one: for example return the information of " LA not allowed " to UE, thereby make UE for example can show that " professional limited, only for urgent " such information is to the user;
Mode two: allow UE to reside among this AP, and when UE attempts from AP acquisition service, this UE is switched to the GSM macrocell.
Wherein, above-mentioned steps 1201 can realize in the following way:
Be similar to the ability arrangement for detecting that having of terminal collected other base station signal for AP installs, thereby make and utilize this device, AP can find whether lay oneself open among certain RAT publicMacro Cell of OOS or IS.
Perhaps, also can pass through in the frequency, between frequency or inter-rat measurement indirectly testing neighbor cell, judge that AP is in oos state or IS state by the terminal that in private base station, is in state of activation.
At the description of above-mentioned flow process, in actual applications, two kinds of processing modes are arranged:
1, AP reports indication need to go up for the processing mode of CN: AP at Iu interface (interface of AP and CN in other words) the residing business state information of this AP (referring to table 7) is issued CN, just often (when variation has taken place) need tell CN, and tell webmaster so that webmaster can in time distribute or reclaim the LAC/RAC that gives AP, the state (IS/OOS, IS or OOS) of present AP.CN can be according to the information that reports of AP then, gives suitable treatments of UE: switch to adjacent macro cell, or the directly access (when AP is oos state) of refusal UE.
2, AP is the processing mode at center: AP obtains UE and AP from CN a CAMEL-Subscription-Information---by Iu interface (interface of AP and CN in other words).AP directly decision is UE is switched to adjacent macro cell, still directly refuses the access (when AP is OOS) of UE with certain reason---make and can only accept emergence call service.
At the method that the embodiment of the invention five provides, the embodiment of the invention also provides the control device of corresponding access private base station, and this device can adopt network equipment to realize that in embodiments of the present invention, this network equipment is CN, and this CN further comprises:
The state judging unit is used to judge the current oos state that whether is in of AP;
The sign allocation units are used for after the state judgment unit judges obtains that AP is current and is in oos state, are that described AP distributes independent Routing Area Identifier;
The error reason Tip element is used for after this AP judges that obtaining this UE is not allowed to access, according to the residing state of this AP self, to the limited reason of described UE prompt service.
In the preferred embodiment of the present invention, this device also can further comprise switch unit, is used for after this AP judges that obtaining this UE is not allowed to access UE being switched to corresponding sub-district.
The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
