As shown in Figure 3, further introduce a kind of changing method that the embodiment of the invention provides, comprising:
Step 301: the measurement result that source HeNB reports according to UE, decision switches to target HeNB with UE.
Step 302: source HeNB sends to switch to HeNB GW and requires (HO Required) message.Identification information, UE unique identification MME UE S1 AP ID, source HeNB in MME that can comprise target HeNB in the HO Required message is the sign eNB UE S1 AP ID of UE distribution and the transparent transmission information of container information such as (Source eNB to Target eNB TransparentContainer) that Target cell is arrived in the cell-of-origin.
HeNB GW judges whether it is the switching between the HeNB under the same HeNB GW after receiving the HO Required message of source HeNB transmission.HeNB is according to the identification information of the target HeNB that carries in the HO Required message, whether inquiry has the identification information of this target HeNB in HeNB GW database, if the identification information of target HeNB is present in the HeNB GW database, then HeNB GW confirms the switching between the HeNB under the same HeNB GW that switches to that source HeNB initiated.
When HeNB GW confirms that source HeNB is required and switches under the HeNB GW switching between the HeNB, can preserve the information in the HO Required message, as record MME UE S1 AP ID, eNBUE S1 AP ID, target HeNB identification information, source HeNB identification information and cell-of-origin transparent transmission information of container to Target cell.The HeNB identification information can comprise cell ID (eNB ID), (Tracking Area Identity is TAI) with CSG ID for the tracing area sign.
Step 303:HeNB GW sends HO Required message to MME.
Identification information, eNB UE S1 AP ID, MME UE S1 AP ID and the cell-of-origin of target HeNB information such as transparent transmission information of container have been carried in this HO Required message to Target cell.HO Required message can further include the access control pattern.
Can comprise an indication in the HO Required message, inform that by this indication the switching that MME source HeNB is initiated is the switching between the HeNB under the same HeNB GW.
Step 304:MME sends handoff request (HO Request) message to HeNB GW.
The identification information that can comprise target HeNB in this HO Request message, carrying tabulation (Evolved Radio Bearer list, E-RAB list), MME UE S1 AP ID, eNB UE S1 AP ID and the cell-of-origin of UE is to the information such as transparent transmission information of container of Target cell.The MME UE S1 AP ID that comprises in this HO Request message and eNB UE S1 AP ID can to send to the MME UE S1 AP ID that comprises in the HO Required message of MME identical with eNB UE S1 AP ID with HeNB GW in the step 303; The MME UE S1 AP ID that perhaps comprises in this HO Request message can to send to the MME UE S1 AP ID that comprises in the HO Required message of MME identical with HeNB GW, eNB UE S1 APID can be different, the eNB UE S1 AP ID that perhaps comprises in this HO Request message can to send to the eNB UE S1 AP ID that comprises in the HO Required message of MME identical with HeNBGW, and MMEUE S1 AP ID can be different; Perhaps, MME UE S1 AP ID that comprises in this HO Request message and eNB UE S1 AP ID can to send to the MME UE S1 AP ID and the eNB UE S1 AP ID that comprise in the HO Required message of MME all inequality with HeNB GW in the step 303.
The security capabilities (UE SecurityCapabilities) of UE or the safe context of UE be can also further comprise in this HO Request message, the security capabilities of UE and the safe context of UE perhaps comprised.The carrying tabulation of UE is preserved by MME, and record UE can set up the kind of carrying, can offer target HeNB and insert judgement.The security capabilities of UE and the safe context of UE send to HeNB GW by MME, further send to target HeNB, then after UE finally switches among the target HeNB, can pass through security capabilities or the safe context assurance target HeNB of UE and the communication security between the UE of UE.
MME can judge whether this UE is the contracted user of target HeNB, and this result is carried in the HO Request message according to the identification information of UE and the CSG ID of target HeNB.
MME can also whether whether the consistent switching of determining that source HeNB initiates be the switching between the HeNB under the same HeNB GW according to the TAI of the TAI of HeNB GW and target HeNB, if the TAI of HeNBGW is consistent with the TAI of target HeNB, then MME confirms the switching between the HeNB under the same HeNB GW that switches to of source HeNB initiation.
Step 305:HeNB GW sends HO Request message to target HeNB.
After HeNB GW receives the HO Request message of MME transmission, can confirm whether the HO Request message of MME transmission in the step 304 belongs to the switching flow of the HORequired message initiation that HeNB GW sends in the step 303, if can send HO Request message to target HeNB.
After HeNB GW receives the HO Request message of MME transmission, if MME UE S1 AP ID in this HO Request message and eNB UE S1 AP ID have at least ID corresponding in and the HO Required message identical, can confirm that then MME sends in the step 304 HO Request message belongs to the switching flow of the HO Required message initiation that HeNB sends in the step 303.Perhaps, cell-of-origin in the transparent transmission information of container of Target cell and the HO Required message, cell-of-origin in this HORequest message is identical to the transparent transmission information of container of Target cell, can confirm that then MME sends in the step 304 HO Request message belongs to the switching flow that HeNB sends in the step 303 HO Required message causes.
The information that HeNB GW comprises in the HO Request message that target HeNB sends can to send to the information that comprises in the HO Request message that HeNB GW sends identical with MME, can send to also that MME UE S1 AP ID and eNBUE S1 AP ID change in the HO Request message that HeNB GW sends to MME, MME UES1 AP ID and eNB UE S1 AP ID after in sending to HO Request message, comprising conversion.For example, the method for conversion can be mapped to one group of new MMEUE S1 AP ID and eNB UE S1 AP ID to MME UE S1 AP ID in the HORequest message and eNB UE S1 AP ID for HeNB GW, and HeNB GW writes down this mapping relations.
Step 306: target HeNB sends handoff request to HeNB GW and replys (HO Request Ack) message.
After target HeNB receives HO Request message, carry out access judgement, target HeNB can be according to the own resource operating position, and whether UE is whether the information such as carrying tabulation of contracted user, UE are carried out the access judgement and allowed to switch with decision.If agree to switch, then court verdict sent to HeNB GW by HORequest Ack message.Comprise identification information, MME UE S1 AP ID, the eNB UE S1 AP ID of source HeNB, the carrying tabulation that allows the carrying tabulation of UE access and/or do not allow UE to insert in the HO Request Ack message.To send to the MME UE S1 AP ID that comprises in the HORequest message of target HeNB identical with eNB UE S1 AP ID for HeNB GW in the MME UE S1 APID that comprises in this HO Request Ack message and eNB UE S1 AP ID and the step 305.
Step 307:HeNB GW sends switching command (HO Command) message to source HeNB.
After HeNB GW receives the HO Request Ack message of target transmission, send HO Command message to source HeNB.
After HeNB GW receives HO Request Ack message, can judge whether this HO Request Ack message belongs to the switching flow that HO Required message is initiated in the step 302, judgement is in order to make HeNB GW know which source HeNB to be HO Command message sent to, and indicates which UE to switch.The process of judging can for: judge whether the HO Request Ack message that receives is the response message that HeNBGW sends to the HO Request message of source HeNB, it is identical to send to the eNB UE S1 AP ID that comprises in the HORequest message of target HeNB according to HeNB GW in the eNB UE S1 AP ID in the HO Request Ack message and the step 305, perhaps, to send to the MME UE S1 AP ID that comprises in the HO Request message of target HeNB identical for HeNB GW in MME UE S1 AP ID in the HO Request Ack message and the step 305, perhaps in the eNB UES1 AP ID in the HO Request Ack message and MME UE S1 AP ID and the step 305 HeNB GW to send to the eNB UE S1 AP ID that comprises in the HO Request message of target HeNB identical with MME UE S1 AP ID, confirm that HO Request Ack message sends to the response message of the HO Request message of source HeNB for HeNB GW.
The information such as carrying tabulation that the carrying that comprises MME UE S1 AP ID, eNB UE S1 AP ID in this HO Command message, allows UE to insert is tabulated and/or do not allowed UE to insert.MME UE S1 AP ID that comprises in this HO Command message and eNB UE S1 AP ID can be MME UE S1 AP ID in the HORequired message in the step 302 and eNB UE S1 AP ID.
Step 308:HeNB GW sends HO Request Ack message to MME.
HeNB GW to MME send HO Request Ack message can so that MME the state of UE is in time safeguarded.
MME may further include step 308 after receiving this HO Request Ack message ': MME sends HO Command message to HeNB GW.HeNB GW ignores this HO Command message after receiving the HOCommand message of MME transmission, can not carry out any processing.
MME can not send HOCommand message to HeNB GW yet after receiving HO Request Ack message.For example, HeNB GW comprises an indication in sending to the HO Request Ack message of MME, and this indication informs that MME need not send HO Command message; Perhaps, if HeNB GW comprises an indication in the HO Required message that MME sends in step 303, this indication informs that the switching that MME source HeNB is initiated is the switching between the HeNB under the same HeNB GW, then MME can not send HO Command message to HeNBGW after the HO Request Ack message that receives HeNB GW transmission; Perhaps, if in step 304, MME has confirmed that source HeNB initiates switches under the same HeNB GW between the HeNB, and then MME can no longer send HO Command message to HeNB GW after receiving HORequest Ack message.
Step 309: source HeNB sends Radio Resource control to UE and moves control (RRC mobilitycontrol) message.
After source HeNB receives the HO Command message that HeNB GW sends, with the result of the switching demand initiated by informing UE in the RRC mobility control message.
Step 310:UE carries out switching.
UE is after the RRC mobility control message that receives source HeNB transmission, and the execution switching separates with source HeNB and target HeNB carries out down-going synchronous, uplink synchronous, sets up RRC and connects.
Step 311: target HeNB sends switching notice (HO Notification) message to MME.
After UE successfully was linked into target HeNB, target HeNB sent HO Notification message to MME, notice UE handover success.
In the prior art, all HeNB must carry out transfer by HeNB GW to the signaling message of MME in the switching set-up procedure, and the node processing time delay that causes consuming time is excessive.In the technical scheme that the embodiment of the invention provides, in switching set-up procedure, HeNB GW is after the switching request acknowledgement message that receives target HeNB transmission, can directly send switching command message to source HeNB, and need not again to send switching request acknowledgement message to MME, wait for again sending to source HeNB again after receiving the switching command message that MME sends, can reduce the handover delay that switches in the set-up procedure like this, realize switching fast, user experience is provided.In addition, because in the method that the embodiment of the invention provides, all be to send signaling message between source HeNB and the HeNB GW and between target HeNB and the HeNB GW by the S1 interface, therefore, the method that provides according to the embodiment of the invention is carried out UE when the switching of indoor base station, need not change the protocol stack of HeNB GW, also need not define new network management configuration and just can realize quick switching.
