Specific embodiment
For the purpose, technical scheme and the advantage that make the embodiment of the invention is clearer, the embodiment of the invention is described in further detail below in conjunction with accompanying drawing.
In the initial deployment stage of PS territory networks such as SAE/LTE, HSPA, HSPA+, WiMAX is that hot zones covers, and the 2G/3G network can be regarded a kind of all standing as to a certain extent.Select for use the LTE network to introduce this programme as the example of PS territory network in embodiments of the present invention, of particular note, the scheme in the embodiment of the invention still goes for said system.
Whether need MSC upgraded to support MSC transmission to the audio call beep-page message of MME, present network can have framework A and two kinds of schemes of framework B if depending on.
As shown in Figure 1, framework A need be to the MSC upgrading to support sending the audio call beep-page message to MME.If do not support BSSAP+ (Base Station System Application PartPlus on the MME, Base Station System Application Part strengthens) agreement and MAP (Mobile Application Part, MAP) agreement, protocols having conversion entity (Protocol Translator) between MME and MSC then, this entity are responsible for BSSAP+ or MAP that the Diameter that MME supports is converted on the MSC to be supported.
As shown in Figure 2, framework B increases logic function body IWF (Interworking Function, network interconnection functive), under this framework, realize CS Fallback, be by IWF transtation mission circuit territory call signaling in the SAE/LTE network, make UE be in the Active state, and then UE is switched to the 2G/3G network, and set up circuit domain call by the HandOver process.Because CS territory call signaling is to set up at the LTE/SAE network, and be to carry out CS Fallback in the mode of switching, so the choice mechanism that the user calls out with tradition the right to choose of this CS business is slightly different, promptly the called subscriber receives the selection that can accept wish after the Setup message according to calling number.
The embodiment of the invention provides a kind of voice call method, as shown in Figure 3, may further comprise the steps:
In step 301, the subscriber equipment that is positioned at packet domain is when receiving from the calling paging of circuit domain or carrying out other call establishments;
In step 302, if described subscriber equipment determines that according to the indication of network side this calling satisfies predetermined condition;
In step 303, return back to this circuit domain, carry out the circuit domain call process.
Introduce the concrete Application Example 1 of method in the network architecture shown in Figure 1 of embodiment below.In the present embodiment, UE is in the LTE network attachment, if during this UE of CS domain user's call, in page phase, the information that UE carries according to beep-page message determines whether carrying out CS Fallback.Specifically as shown in Figure 4.
Step 401 to 403 in, MSC sends CS Page information to MME, this CS Page information can be carried CS territory calling indication message; In the present embodiment, CS territory calling indication message can be calling number or caller type or other information that can indicate the CS territory to call out of network side judgement back.
It needs to be noted, this CS territory calling indication message is used for indication from CS territory calling party, but be not limited to is calling number or caller type herein, is can be as CS territory calling indication message from CS territory caller party information as long as can indicate the calling subscriber.CS territory calling indication message in the embodiment of the invention only is for convenience of description and the title that adopts.This title can not limit embodiment of the invention applicable scope, does not promptly perhaps have the title of CS territory calling indication message in some system, still, can not think thus that the technical scheme in the embodiment of the invention can not be applicable to these systems.
MME sends paging request message by eNodeB to UE after receiving this CS Page information.It is a paging from CS that CN Domain Indicator in this message indicates this, and carries CS territory calling indication message.UE receives paging request message
Alternatively, if MME supports Base Station System Application Part+, MSC directly issues MME with beep-page message, otherwise can be dealt into the protocol conversion entity, is dealt into MME through after the protocol conversion of this entity.
In step 404, after UE receives paging request message, parse CS territory calling indication message wherein, judge whether CS Fallback.
Such as, if CS territory calling indication message is a calling number, UE is as carrying out voice call with the indicated calling subscriber of this calling number, then CS Fallback is carried out in decision.
For another example, if CS territory calling indication message is a caller type, if the call request that this classification calling subscriber initiates is accepted in the UE decision, then CS Fallback is carried out in decision.
If UE decision carrying out CS Fallback, then send and accept indication to the LTE/SAE network, whether state that the network based UE of LTE/SAE is present and objective network support the PS business to initiate PS switching, RAU (routing area update, the route zone position is upgraded) or LAU (location areaupdate, the position, lane place is upgraded) process carry out CS Fallback.
Call out if UE refuses this CS, then send the refusal indication to the LTE/SAE network, MME will return this refusal indication and give MSC; Perhaps UE does not respond any message, and network side is waited for the overtime release of page response.In addition, such as, UE thinks that this calling number is the user on the blacklist of refusal conversation, then can also shield this class beep-page message that CS calls out by terminal operation, perhaps sends indication signaling by terminal operation to network and informs that network do not send out this class beep-page message to terminal this moment.
In the present embodiment, UE can be in paging, the CS territory calling indication message of carrying in the beep-page message according to CS, and as calling number, caller type, UE user selects whether to carry out CS Fallback according to this information.The decision mechanism that makes UE carry out CS Fallback depends on the autonomous selection of UE fully, embodied the wish whether UE is ready to accept this calling.For calling out, make UE can avoid unnecessary rollback from the harassing and wrecking in CS territory.Such as, if this UE this moment is just comparing important PS when professional, and the CS network is not supported the PS business, can avoid this moment UE to sacrifice existing P S business and carry out CS Fallback.
In addition, in the present embodiment,, can make eNB possess the ability that judges whether to carry out CSFallback according to the indication of network side by eNB is configured if do not consider the CS Fallback process of UE right to choose.Specifically, can be operator's configuration, perhaps receive the indication of UE to network side.After eNB receives paging request message from MME, can judge that according to the CN Domain Indicator in this message this is the paging from CS, and according to the CS territory calling indication message of carrying in this message, CS territory calling indication message can be calling number or caller type or other information that can indicate the CS territory to call out of network side judgement back, eNB can stop to continue issuing page message, carry out processes such as UE switching, make UE carry out the process of CS Fallback.
This scheme makes network side also possess identification from the caller paging of CS territory, when UE does not participate in determining whether to carry out CS Fallback, also can finish definite process of CS Fallback.
Introduce the concrete Application Example 2 of method in the network architecture shown in Figure 1 of embodiment below.In the present embodiment, UE is in the LTE network attachment, if during this UE of CS domain user's call, the information that UE carries according to setup message determines whether carrying out CS Fallback.Specifically as shown in Figure 5.
Step 501 to 503 in, MSC sends beep-page message to MME, is transmitted to UE by MME.
Alternatively, if MME supports Base Station System Application Part+, MSC directly issues MME with beep-page message, otherwise can be dealt into the protocol conversion entity, is dealt into MME through after the protocol conversion of this entity.
Step 504 to 506 in, UE returns page-response message, MME gives MSC with this forwards.
In step 507, be optional authentication, security process.
Step 508 to 509 in, MSC issues Setup message, can carry CS territory calling indication message in this message; In the present embodiment, CS territory calling indication message can be calling number or caller type or other information that can indicate the CS territory to call out of network side judgement back.MME gives UE with this forwards.
In step 510, after UE receives setup message, parse CS territory calling indication message wherein, judge whether CS Fallback.
UE, does not repeat them here shown in step 404 deterministic process of CS territory calling indication message.
Step 511 to 512 in, after UE return back to the CS territory, send call confirm message in the CS territory to MSC, and finish follow-up CS territory call signaling handshaking procedure.
Present embodiment is different with previous embodiment to be, the CS paging is finished in the LTE network, and after UE receives setup message, just according to the CS territory calling indication message of carrying in the steup message, as calling number, caller type, UE user selects whether to carry out CS Fallback according to this information.
Introduce the concrete Application Example 3 of method in the network architecture shown in Figure 1 of embodiment below.In the present embodiment, UE is in the LTE network attachment, if during this UE of CS domain user's call, network earlier with earlier with the form of LTE short message with CS territory calling indication message, be issued to UE such as calling number or caller type.
(this beep-page message CS territory calling indication message when MME receives beep-page message from MSC, such as calling number or caller type), will be with the form notice UE of LTE short message, the user selects whether to return back to CS in view of the above, if the UE decision return back to the CS territory, then send and accept indication to the LTE/SAE network, whether state that the network based UE of LTE/SAE is present and objective network support the PS business to initiate PS switching, RAU or LAU process is carried out CS Fallback.Call out if UE refuses this CS, then return the refusal indication and give the LTE/SAE network, MME will return this refusal indication and give MSC.UE returns the MSC page-response message after getting back to CS territory network.
Present embodiment is different with previous embodiment to be, the CS paging is finished in the LTE network, and after UE receives the LTE message that the LTE network sends, just according to the CS territory calling indication message of carrying in this message, as calling number, caller type, UE user selects whether to carry out CSFallback according to this information.
Aforementioned several embodiment is based on the scheme of framework A, introduces the scheme of the embodiment of the invention based on framework B below.
Introduce the concrete Application Example 4 of method in the network architecture shown in Figure 2 of embodiment below.Framework B increases logic function body IWF, realizing CS Fallback under this framework, is to send CS territory call signaling by IWF in the SAE/LTE network, makes UE be in the Active state, and then UE is switched to the 2G/3G network, and set up circuit domain call by the HandOver process.In the present embodiment, UE is in the LTE network attachment, if during this UE of CS domain user's call, the information that UE carries according to setup message determines whether carrying out CS Fallback.Specifically as shown in Figure 6.
Step 602 in the present embodiment to step 607 process basic with Fig. 5 in similar, difference is the difference owing to framework, the message in the present embodiment is transmitted by IWF.
In step 607, after UE receives setup message, parse CS territory calling indication message wherein, judge whether CS Fallback.UE, does not repeat them here shown in step 510 deterministic process of CS territory calling indication message.After if UE return back to the CS territory, send call confirm message in the CS territory to MSC, and finish follow-up CS territory call signaling handshaking procedure.After switching is finished, forwarded for the 612nd step to, return connect message in the CS territory of objective network.If the UE refusal then returns Reject Indication message and gives network, after LTE/SAE resolves this Indication message, can not carry out ensuing hand-off process.
The present embodiment effect is that in framework B, the CS paging is finished in the LTE network, and after UE receives setup message, just according to the CS territory calling indication message of carrying in the steup message, as calling number, caller type, UE user selects whether to carry out CS Fallback according to this information.
In network, UE is in the LTE network attachment, when if UE will carry out with CS territory user's short message service, consider that receipts/short-message sending required time is shorter, and be to transmit by means of signaling, to cause unnecessary spending but also can increase the battery of mobile phone power consumption if Fallback returns CS, there is no need in the time of can thinking receipts/short-message sending UE Fallback to CS:
(1) for sending SMS message, NAS (none accesssignaling, the Non-Access Stratum signaling) signaling that can directly pass through the LTE/SAE network sends;
(2) for receiving short message, SMS-GMSC directly is dealt into the short message route on the MME, and the MME calling user sends SMS message.
Introduce the embodiment of the implementation of short message service below.Specifically as shown in Figure 7.
In step 701, Short Message Service Center (SMS-SC) sends SM (short message, short message) to SMS gateway (SMS-GMSC is called for short SMS-G).
In step 702, SMS-G checks the address of object UE, sends Send Routeing Info ForShort Message message and carries out routing inquiry to corresponding HSS.
In step 703, after HSS checked user's subscription data, if UE is allowed to receive this short message, then HSS returned Send Routeing InfoFor Short Message Result message and gives SMS-G.The MME, the MSC address that comprise the current place of UE in this message.
In step 704, when having the E/Gd interface between SMS-G and the MME, SMS-G sends to MME with short message.If there is no this interface, then SMS-G will issue MSC to short message, by MSC by being dealt on the MME like Gs interface.Secondly, if the last support of MME MAP, then the direct short-message sending of SMS-G is to MME, otherwise can send to protocol conversion entity ProtocolTranslator, undertaken being dealt on the MME after the protocol conversion between SMS-G and the MME by Protocol Translator.
In step 705, MME sends short messages to UE.
In step 706, MME returns Forward Short Message Result message to SMS-G and indicate short message to send successfully.If short message sends failure, and failure is former in provisional reasons such as no-response paging, memory capacity have expired, MME will indicate the reason of failure and put a certain position to show failure cause on MME in this message, SMS-GMSC sends SMS message status message (carrying failure cause in this message) to HSS after receiving this failed message, and HSS puts corresponding failure cause position according to this status message.If in follow-up time, MME according to UE to its message (as pageresponse, sm memory capacity available) but know and can reach or the memory space time spent this moment, can send SMS message prepare message to HSS so that attempt this transmission again of short message.
In step 707, after SMS-G receives Forward Short Message Result,, then send out Delivery Report message and give SMS-SC if this message indication short message successfully sends.If above-mentioned message indication short message sends failure, SMS-G can not attempt sending short messages to MSC, but put a certain position thereon, and return SMS-SC Delivery Report message and inform that this short message sends failure and waits for follow-up continuation trial so that follow-up short message sends successfully back reception from the Forward ShortMessage Result message of MME.
Describe above is to receiving the description of short message, for sending SMS message, similar with the process of above-mentioned reception short message, the UE that LTE adheres at first is dealt into MME with short message, MME judges that according to the indication of message this message is short message service, can adopt following dual mode to continue to handle this business:
1) MME sends to SMS-GMSC by the E/Gd interface with short message, carries out follow-up processing by SMS-GMSC.
2), then can do follow-up processing by MSC by short message being sent on the MSC like Gs interface if there are not the E/Gd interface in MME and SMS-GMSC.
Repeat no more for the process that sends SMS message at this.By present embodiment as can be seen, pass through this programme, at the UE in PS territory when the user with the CS territory carries out short message service, can be according to the indication of network side, transmit by means of signaling, return CS without Fallback, thereby reduced unnecessary spending but also can reduce the battery of mobile phone power consumption.
Can realize optionally carrying out CS Fallback by above-mentioned each enforcement, if UE decision carrying out CS Fallback, the target CS territory is the circuit-domain network of 2G or 3G so, and decision UE return back to 2G network or 3G network, can be by the specific embodiment of following implementation.
1) determine preferred 3G network by network (as eNB), promptly UE is when carrying out CS Fallback, and network (as eNB) is informed UE with the Target cell of 3G network, and UE return back to the CS territory of this Target cell.
2) network (as eNB) is informed UE with the 2G of target and the relevant information of 3G network, and UE selects to return back to 2G network or 3G network according to oneself ability and business support ability.
