As shown in Figure 4, concrete handling process is following:
Step 401: grand RNC periodically generates the dynamic Cell ID of all sub-districts under it, and wherein RNCID is its true RNC ID; Grand RNC preserves the relation of dynamic Cell ID and true Cell ID; Preserve this corresponding relation can be used for operator on querying server through carrying out information inquiry alternately with macro network system; Issue the dynamic Cell ID of all sub-districts under this RNC through system message update.
Step 402:AP start powers on when carrying out the automatic adjacent section search or carrying out the search of periodicity automatic adjacent section, from the system message of the grand RNC broadcasting of eating dishes without rice or wine, gets access to dynamic Cell ID and real RNC ID, with this parameter configuration macrocell adjacent area;
Step 403: when certain UE of AP sub-district need proceed to the switching of grand network, AP initiated switching flow, and brought CN with the dynamic Cell ID of target macro RNC with real RNC ID; Specifically can for: AP through IAD (Access Gateway, AG) sending migration to CN must (RelocationRequired) message, initiates switching flow, brings CN through Relocation Required message with the dynamic CellID of target macro RNC;
Step 404: comprise real RNC ID because AP sends to through AG in the message of CN, CN sends message according to RNC ID to Target RNC and continues switching flow.Specifically can for: CN can issue correct Target RNC with handoff request (Relocation Request) message according to RNCID;
Step 405: grand RNC converts dynamic Cell ID into true Cell ID according to the mapping relations of the dynamic CellID that self preserves with true Cell ID; Specifically can for: convert the dynamic Cell ID in handoff request (RelocationRequest) message into true Cell ID; RNC finds the respective cell of corresponding base station (NodeB) according to above-mentioned real CellID, on this NodeB, set up Radio Link (RadioLink, RL)
Step 406:RNC sends message to CN and informs that the core net Target cell has been accomplished to switch and prepare; Specifically can for: send migration request and reply (Relocation RequestAck) message, prepare to inform that the core net Target cell has been accomplished to switch;
Step 407, step 408:CN sends message to femto (Femto) system (comprising AP and AG) and informs and can trigger subscriber equipment by AP (User Equipment UE) has switched; Specifically can inform that AP can trigger UE and switch for sending migration control (Relocation Command) message;
Step 409:AP to UE initiate radio resource control (Radio Resources Control, RRC) and radio bearer (Radio Bearer RB) reconfigures (Reconfiguration);

Because dynamically the RNC ID in the global cell identity is real RNC ID; Report dynamic cell ID wherein to comprise real RNC ID according to original flow process AP, core net can find Target RNC according to real RNC ID, and CN sends the dynamic cell sign to Target RNC and carries out the sub-district switching; Owing to preserved the corresponding relation of dynamic cell sign and true cell sign at RNC, RNC can get access to the true cell sign of Target cell according to the dynamic cell sign; Thereby when using the dynamic cell sign, UE initiates to switch to macrocell from the Femto sub-district can be successful.Because is dynamic Cell ID at RNC through the Cell ID that eats dishes without rice or wine to send to AP, illegal third party can not get access to the corresponding relation in Cell ID and geographical position, sub-district, thereby has improved Information Security.
Embodiment four; Present embodiment will use dynamic Cell ID and true Cell ID mapping relations and dynamically RNC ID and RNC ID describe as example with regard to embodiment two; In the present embodiment; AP converts dynamic CellID and RNC ID into really, and we are called that to convert dynamic overall Cell ID into real overall Cell ID as shown in Figure 5 for convenient narration, may further comprise the steps:
Step 501: grand RNC periodically generates its dynamic overall Cell ID of all sub-districts down.The dynamic overall Cell ID that supposes certain sub-district of generation is Para1;
Step 502: after dynamic overall Cell ID generates and finishes; Grand RNC sends to RNC network management system (processing of RNC webmaster for ease, all grand RNC can be provided with unified dynamic overall Cell ID and generate cycle and time point) with the mapping relations of dynamic overall Cell ID and true overall Cell ID.Further; In order to guarantee that grand RNC upgrades before the dynamic overall CellID in system message; AP has got access to up-to-date mapping relations information; Grand RNC can be provided with a back off timer t1, after the dynamic overall CellID in certain cycle generates, postpones t1, and RNC upgrades the dynamic overall CellID information that issues this cycle again in the system message of eating dishes without rice or wine;
After step 503:RNC webmaster is received the mapping relations that each RNC reports, the mapping relations information of all RNC is merged, be assembled into a file, be delivered to AP system (AP webmaster and AP) through interface with the AP webmaster.
Step 504:AP webmaster receives the overall Cell ID of grand RNC webmaster and the mapping relations of true overall Cell ID, is handed down to all AP of its management;
Step 505:AP upgrades the overall Cell ID of preservation on it and the mapping relations of true overall Cell ID;
Step 506: grand RNC upgrades in the system message of eating dishes without rice or wine and issues its dynamic overall Cell id information of all sub-districts down, comprising Para1; The above-mentioned system message of eating dishes without rice or wine can be received at the AP that eats dishes without rice or wine to receive message, UE etc.
Step 507: when AP carries out the automatic adjacent section search, get access to dynamic overall Cell IDPara1 from eating dishes without rice or wine.At this moment, AP finds the corresponding true overall Cell ID of Para1 from the overall Cell ID of its preservation with the mapping relations of true overall Cell ID, with true overall Cell ID configuration macrocell adjacent area.Follow-up AP adopts true overall Cell id information to the switching and AP self correlation properties of macrocell.
After step 507, identical because AP has got access to true overall Cell ID with the switching flow of prior art, repeat no more.
In the above-mentioned execution mode, obtain true Cell id information in the AP side and also got access to real RNC ID simultaneously, realize dynamic conversion, be used for switching and the AP correlation properties of AP to grand network to true Cell ID by AP.Adopt the method, the RNC ID among the Cell ID also can carry out mobilism to be handled, and repeats no more at this.
Because AP has got access to the mapping relations of dynamic global cell identity and true global cell identity; AP can get access to real global cell identity according to these mapping relations and also get access to real RNC ID simultaneously after receiving dynamic global cell identity; AP can carry out follow-up operation according to original method after getting access to true global cell identity; Thereby when using the dynamic cell sign, UE initiates to switch to macrocell from the Femto sub-district can be successful.
Embodiment five; Present embodiment will use dynamic Cell ID and true Cell ID to shine upon key and dynamic RNC ID and RNC ID with regard to embodiment two and describe as example; In the present embodiment, AP converts dynamic CellID and RNC ID into really, and we are called and convert dynamic overall Cell ID into real overall Cell ID for convenient narration; As shown in Figure 6, may further comprise the steps:
Step 601:RNC webmaster periodically generates dynamically and true overall Cell ID transition key K1, and mark K1 rise time t1; The mode of the generation transition key of periodic can improve the difficulty that key is cracked, thereby improves fail safe further.If do not adopt the mode that periodically generates key can realize that the embodiment of the invention will not limit yet.
Step 602: after generating key K 1, the RNC webmaster is handed down to RNC and AP webmaster with K1, has 1 rise time of key K mark t1 in the transmission information; Carry out conversion process according to the 1 couple of overall Cell ID of key K that gets access to respectively by RNC and AP system (AP webmaster and AP) then:
Step 603:RNC side, the key K 1 that employing gets access to is encrypted the true overall CellID of all sub-districts under it, obtains dynamic overall Cell ID (for example this overall Cell ID is Para1), and issues Para1 at the system message update of eating dishes without rice or wine;
The key K 1 that the AP webmaster of step 604:AP system side will have a rise time mark sends to all AP of its management.AP at a time carries out the automatic adjacent section search, and record time of implementation t2.The last key that can preserve a plurality of generation cycles of AP; AP is according to adjacent area t2 search time and the time relationship of each key rise time (beginning comparison from time t1 the latest); Judge and select correct key; Dynamic overall Cell ID to searching deciphers, and obtains true overall Cell id information, with true overall Cell ID configuration macrocell adjacent area.Follow-up AP adopts true overall Cell id information to the switching and AP self correlation properties of macrocell.
Because AP has got access to the transition key of dynamic global cell identity and true global cell identity; AP can get access to real global cell identity according to this key after receiving dynamic global cell identity; AP can carry out follow-up operation according to original method after getting access to true global cell identity; Thereby when using the dynamic cell sign, UE initiates to switch to macrocell from the Femto sub-district can be successful.Because is dynamic Cell ID at RNC through the Cell ID that eats dishes without rice or wine to send to AP, illegal third party can not get access to the corresponding relation in Cell ID and geographical position, sub-district, thereby has improved Information Security.
