Description

Paging process, method for information display, Apparatus and system

Technical field

The present invention relates to communication technical field, particularly to a kind of paging process, method for information display, dress Put and system.

Background technology

Evolved universal mobile communication system (Universal Mobile Telecommunication System, letter Claim UMTS) land radio access web (Evolved Universal Mobile Telecommunication System Territorial Radio Access Network, is called for short E-UTRAN) and evolution block core net (Evolved Packet Core is called for short EPC) constitutes evolved packet system (Evolved Packet System, is called for short EPS).Owing to some operator wishes after disposing EPS network still by traditional 2/3G wireless access network and circuit (Circuit Switching is called for short CS) domain core net provide voice industry Business, EPS network provides only packet (Packet Switching is called for short PS) domain data service and accesses, In a period of time, EPS network coexists with tradition 2/3G circuit-domain network.Due to most of terminal (User Equipment, is called for short UE) examine in terms of reducing cost, space interface signaling saving, minimizing battery consumption etc. Consider, the wireless connections under synchronization can only keep a kind of wireless access technology, it is therefore proposed that " electricity Road domain dropping " i.e. the solution of CS Fallback, UE can pass through global system for mobile communications (Global System for Mobile Communications, be called for short GSM)/improve data rate GSM evolution Technology (Enhanced Data rate for GSM Evolution is called for short EDGE) wireless access network (GSM EDGE Radio Access Network, be called for short GERAN), UTRAN, CDMA (Code Division Multiple Access, is called for short CDMA) wireless access network (CDMA Access Network, Be called for short CDMAAN) etc. 2/3G access network access circuit domain core net, it is also possible to pass through E-UTRAN Access EPC.UE is after EPS side is adhered to, MME Yu UE of UE registration registers in circuit domain side MSC set up association, the interface between MME and MSC in EPS standard be referred to as SGs interface. After SGs interface conjunctionn is set up, when not having circuit domain speech business, UE is at E-UTRAN side joint Enter EPC, it is possible to use Packet Service.If desired carrying out speech business, UE then can pass through CS Fallback Flow process is switched to GERAN/UTRAN/CDMA AN side, sets up CS according to original CS territory flow process and exhales Being link, carry out speech business, this process is known as CS Fallback.Speech business is carried out at UE Time, the packet bearer of UE would generally be hung up (Suspend) by network, and under suspended state, network is still It is left the IP address of the packet bearer of UE distribution, but now can not transmitting grouped data, i.e. data industry Business is interrupted.When the speech business of UE terminates, network can pass through recovery (Resume) flow process Recovering the packet bearer of UE, now UE just can reuse Packet Service.

As a example by UE accesses CS domain core net by UTRAN, when MME takes with mobile switching centre Business device (Mobile Switching Center Server is called for short MSC) (SGs after SGs interface conjunctionn is set up Interface is set up and is represented that UE is currently accessed EPC by E-UTRAN and registered at MSC by EPC), If MSC receive a calling party to UE initially address message (Initial Address Message, It is called for short IAM) after, then forward paging request message to MME.MME receives paging request message After, if UE is currently at connection status, MME is the most directly by the signaling between MME and UE the most even Connect and send page notification message to UE.After UE receives this page notification message, according to the CS of oneself Service condition current in Fallback configuration and UE, can be with display reminding information to carry to the user of UE Show currently there is an audio call, ask the user whether to interrupt current data service and be switched to circuit domain Answer this audio call.When UE gets the interruption current data service of user's input, answers voice and exhale After the order cried, then UE can notify that MME performs CS Fallback flow process, to be switched to CS territory Set up CS territory call link and carry out speech business, and current packet bearer is switched to UTRAN side also Hang up；Answer the order of audio call when UE gets the refusal of user's input, then UE can be to MME Sending refusal and answer message, MME receives after refusal answers message, by SGs interface notification MSC Called subscriber refuses audio call, and MSC refuses flow process according to paging failure or UE and responds to calling party, Now unaffected in the current ongoing data service of E-UTRAN side UE.

In realizing process of the present invention, inventor finds that in prior art, at least there are the following problems: work as UE After showing above-mentioned information, needing the user of UE to carry out confirmation is " to interrupt current data service, connect Listen audio call " or " continue current data service, refusal answers audio call ".Above-mentioned confirmation operates Being the mutual process of a personal-machine, the user of UE, from seeing this information, to judging, and passes through Certain form sends confirmation to UE, it may be necessary to several seconds to tens seconds, when the most longer one section Between.And MSC is from sending after paging request message to MME, it is constantly in and waits UE response paging State, usual MSC etc. to be paged time time of a length of more than 10 seconds, in CS Fallback scheme, If owing to wait user's confirmation that CS Fallback is operated and cause MSC can not receive UE for a long time Page response, MSC then cannot correctly distinguish be E-UTRAN side paging UE failure, or Paging UE in E-UTRAN side is successful, and UE is waiting the confirmation of user, thus causes MSC meeting Process according to paging failure, such as, terminate call flow, or turn to 2/3G access network to enter mistakenly Row paging；In original CS territory, to called subscriber's paging success and establish CS territory call link After will return called terminal ringing message to calling party, calling party now can hear successive sounds, normal condition Under have only to time of several seconds, and in CS Fallback scheme, waiting that called subscriber confirms CS During Fallback operation, calling party is likely to be due to can't hear successive sounds for a long time, is mistakenly considered network Occur in that fault actively stops this calling, thus have impact on being normally carried out of speech business.

Detailed description of the invention

Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the present invention, and It is not all, of embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art are not making Go out the every other embodiment obtained under creative work premise, broadly fall into the scope of protection of the invention.

Due to the target CS domain systems different in the CS Fallback scheme entirety to CS Fallback scheme The thought of framework and the present invention does not affect, and in order to simplify description, accesses CS with UE by UTRAN It is real that domain core net and UE describe invention as a example by accessing the CS Fallback between EPC by E-UTRAN Execute the technical scheme of example.

The schematic flow sheet of the paging processing method that Fig. 1 provides for the embodiment of the present invention one, in the present embodiment Callee UE currently by E-UTRAN access EPC, callee UE registration MME with called The MSC of side's UE registration has passed through SGs interface and has set up association, as it is shown in figure 1, the present embodiment is permissible Comprise the following steps:

Step 101, MME receive the paging request message that callee MSC sends；

Step 102, when callee UE is in connection status, MME to callee UE send paging Notification message, and the paging state message of callee UE is returned to callee MSC.

In the present embodiment, MME receive callee UE registration MSC paging request message it After, if it find that callee UE is in connection status, then MME is except sending CS to callee UE Territory page notification message, also returns paging state message to MSC, to indicate callee UE to MSC Receive page notification message, thus avoided MSC and wait that user is confirmed whether to hold at callee UE It is judged as mistakenly during row CS Fallback flow process in E-UTRAN side paging called partner UE failure The situation carrying out corresponding fault processing occurs, and improves the success rate of calling.

The schematic flow sheet of the paging processing method that Fig. 2 provides for the embodiment of the present invention two, in the present embodiment Callee UE currently by E-UTRAN access EPC, callee UE registration MME with called The MSC of side's UE registration has passed through SGs interface and has set up association, as in figure 2 it is shown, the present embodiment is permissible Comprise the following steps:

The MSC of step 201, callee UE registration receives the IAM, this IAM that calling party sends Message carries mobile station ISDN (Mobile Station ISDN, the abbreviation of callee UE MSISDN), MSC searches called according to the MSISDN of callee UE entrained in IAM message The context of side UE, obtains IMSI International Mobile Subscriber Identity (International corresponding for callee UE Mobile Subscriber Identity, is called for short IMSI), registered to callee UE by SGs interface MME sends paging request message, carries the IMSI of callee UE in this paging request message.

Wherein, above-mentioned IAM is also possible to carry the identification information of calling party UE, such as: calling party The MSISDN of UE, can correspondingly carry the mark letter of calling party UE in the most above-mentioned paging request message Breath；

Step 202, MME receive paging request message, according to quilt entrained in paging request message The IMSI of the side of crying UE searches the context of callee UE, according to record in the context of callee UE Condition adjudgement callee UE when being in connection status, by Non-Access Stratum (Non Access Stratum, It being called for short NAS) message sends CS territory page notification message to callee UE.

If the paging request message that MSC is sent in step 201 carries the mark of calling party UE Information, i.e. MME obtain the identification information of calling party UE from MSC, such as: calling party UE's MSISDN, then in this step, the MSISDN of calling party UE can be included in the paging of CS territory by MME In notification message；

Step 203, MME return the paging state message of callee UE to MSC, to notify MSC Callee UE has received page notification message and has started a personal-machine interactive program；

Step 204, MSC receive paging state message, extend the CS territory paging waiting callee UE The time of response, and according to preset strategy to the MSC return CS territory call link that calling party UE registers (Address Complete Message is called for short the called terminal ringing message i.e. address completion message set up ACM), the MSC for calling party UE registration forwards this called terminal ringing message to calling party UE；

Step 205, callee UE receive CS territory page notification message, according to the CS pre-set Fallback configuration information display reminding information, performs CS Fallback flow process to ask user to be confirmed whether.

If the CS territory page notification message that MME is sent in step 202. carries calling party UE Identification information, i.e. callee UE obtains the identification information of calling party UE, such as from MME: main The MSISDN of the side of crying UE, then in this step, callee UE can comprise calling party in information The MSISDN of UE；

Step 206, callee UE get user input execution order i.e. interrupt current data service, Carry out the order of speech business, the selection of UE record user, and send service request (Service to eNB Request) message；

Step 207, eNB receive service request information, forward this service request information to MME；

Step 208, MME receive service request information, initiate CS Fallback flow process.

So far, callee UE is switched to CS territory, sets up CS territory call link and receives calls, and will Current PS carrying is switched to UTRAN side and hangs up.

It should be noted that in the present embodiment step 201, MSC can uniquely mark possibly through other Know the other type of identification information of callee UE, such as: the Temporary Mobile Station Identity of UE in circuit domain The MME of UE in (Temporary Mobile Station Identity is called for short TMSI), EPS network Temporary Mobile Station Identity (MME Temporary Mobile Station Identity is called for short M-TMSI) etc. Mark, does not limits this embodiment of the present invention.

In the present embodiment, MSC is constantly in the shape waiting callee UE response paging before the step 204 State, MSC can be using two kinds of message as the legal response to the paging request message that it sends to MME:

A) user of callee UE selects " acceptance " CS Fallback: callee UE is in CS territory one Service request is initiated in side, MSC using the service request information that receives in side, CS territory as page response；

B) user of callee UE selects " refusal " CS Fallback, or (example within the time set Such as 20 seconds) do not confirm, the most do not select " acceptance " CS Fallback, the most do not select " to refuse The Fallback of CS absolutely ": callee UE sends refusal to MME answers message, and MME is connect by SGs User's refusal of mouth notice MSC callee UE receives calls, and MSC is according to paging failure or user Rejection returns response to calling party.

In the embodiment of the present invention, callee UE responds the paging of CS territory, if no special instructions, refers to positive reason Under condition, the user of callee UE selects " acceptance " CS Fallback, callee UE to be switched to 2/3G and connect Network, send, to MSC, the situation that service request information pages reply as CS territory in side, CS territory.

After in the present embodiment step 204, MSC receives paging state message, can be according to preset strategy Called terminal ringing message is returned to calling party.Preset strategy therein can be that MSC is immediately to calling party UE The MSC of registration sends this called terminal ringing message.Preset strategy can also be rear to master in preset time period The MSC of the side of crying UE registration forwards this called terminal ringing message, such as: MSC can start one 12 seconds Paging waiting timer.If the most not receiving callee UE's after paging waiting timer time-out CS territory pages reply, and MSC then sends called terminal ringing message to calling party, continues waiting for callee simultaneously The CS territory of UE pages reply.If have received callee UE's before paging waiting timer time-out CS territory pages reply, and MSC then can stop paging waiting timer, sets up CS territory with callee UE Call link, returns called terminal ringing message to calling party.

The present embodiment step 203 can have two kinds of executive modes: a kind of for performing step 202 the most immediately Perform；After another kind is for performing step 202, start an intervalometer, after this timer expiry Perform again.Such as one 10 seconds waiting timer, this timer duration should be less than the paging etc. of MSC Treat that the user of the MSC and calling party UE of intervalometer and calling party UE registration typically waits for called terminal ringing and disappears The duration of breath.After this waiting timer time-out on MME, the most do not receive callee UE and connect By or time refusal CS Fallback flow process is responded, MME just sends paging state message to MSC, Although it is known that be not received by the CS territory of callee UE for a long time after MSC receives paging state message Page response, but callee UE has received CS territory page notification message, is waiting that it is used Family confirms or just during the initiation of CS Fallback flow process, and MSC extends wait callee UE's The time of CS territory page response, and return what CS territory call link was set up according to preset strategy to calling party Called terminal ringing message.

Alternatively, the present embodiment step 203 can also be with the MME in step 202 to callee UE The step sending CS territory page notification message performs simultaneously, it is possible to reach effect same.

Under normal circumstances, the duration of MSC upper paging waiting timer (including retransmitting) depends on MSC Wait the duration of UE response beep-page message and the calling retransmission number of times of MSC, such as: MSC waits UE Response beep-page message time a length of 5 seconds, the calling retransmission number of times of MSC is 3 times, then this paging etc. are undetermined Time device duration be then 15 seconds, if the most do not receive after timer expiry callee UE return seek Exhaling response, in prior art, MSC will be considered that at E-UTRAN side paging UE unsuccessful and stop this Calling, returns error message to calling party；Or think that callee UE is not at the E-UTRAN area of coverage In, then this callee UE in UTRAN side again paging, and now callee UE is actually In the E-UTRAN area of coverage, above-mentioned again both increased at UTRAN side paging called partner UE UTRAN side without specific electric load, again can not successful page to this callee UE.Simultaneously because calling party The user of UE may can't hear successive sounds for a long time, it is likely that think network occur in that fault and actively in Only this calling.

MSC in the present embodiment is owing to having been obtained for before receiving the page response of callee UE The paging state message of the callee UE that MME returns, has obtained CS territory paging request message in advance Through being successfully delivered to be in the callee UE of connected state, simply the user of callee UE may also the most really Recognize and whether perform CS Fallback flow process or it has been acknowledged that whether perform CS Fallback flow process, but phase The CS territory page response answered or refuse information the most do not arrive MSC.Therefore MSC can continue waiting for by Page response rather than the termination of the side of crying UE call or turn to 2/3G access network to carry out paging, and MSC can send called shaking in advance when UE can not timely respond to CS paging request in good time to calling party Bell message, it is to avoid calling subscribe active termination calling, improves success rate of communication.

In the present embodiment, MME is after the paging request message receiving MSC, if it find that called Side UE is in connection status, then except sending CS territory page notification message to callee UE, it is also possible to Paging state message is returned, to have received page notification disappear to MSC instruction callee UE to MSC Breath, thus avoid MSC and wait that user is confirmed whether to perform CS Fallback flow process at callee UE Period is judged as carrying out corresponding fault processing in E-UTRAN side paging called partner UE failure mistakenly Situation occur, improve the success rate of calling.MSC can also return to calling party according to certain strategy Return called terminal ringing message, thus at callee UE, the user avoiding calling party UE waits that user confirms to be Judge during no execution CS Fallback flow process that the situation that callee terminates without response to call is sent out mistakenly Raw.

The schematic flow sheet of the paging processing method that Fig. 3 provides for the embodiment of the present invention three, in the present embodiment Callee UE currently by E-UTRAN access EPC, callee UE registration MME with called The MSC that side's UE registration is bought has passed through SGs interface and has set up association, as it is shown on figure 3, the present embodiment can To comprise the following steps:

The MSC of step 301, callee UE registration receives the IAM, this IAM that calling party sends Carrying the MSISDN of callee UE in message, MSC is according to callee entrained in IAM message The MSISDN of UE searches the context of callee UE, obtains IMSI corresponding to callee UE, logical Cross the MME transmission paging request message that SGs interface is registered, this paging request message to callee UE In carry the IMSI of callee UE.

Step 302, MME receive paging request message, according to quilt entrained in paging request message The IMSI of the side of crying UE searches the context of callee UE, according to record in the context of callee UE Condition adjudgement callee UE when being in connection status, sent to callee UE by NAS layer message CS territory page notification message.

If the paging request message that MSC is sent in step 301 carries the mark of calling party UE Information, i.e. MME obtain the identification information of calling party UE from MSC, such as: calling party UE's MSISDN, then in this step, the MSISDN of calling party UE can be included in the paging of CS territory by MME In notification message；

Step 303, callee UE receive CS territory page notification message, according to the CS pre-set Fallback configuration information determines display reminding information, performs CS Fallback to ask user to be confirmed whether Flow process, and return to waiting for indicating message, to notify that MME starts man-machine interaction program to MME.

If the CS territory page notification message that MME is sent in step 302 carries calling party UE Identification information, i.e. callee UE obtains the identification information of calling party UE, such as from MME: main The MSISDN of the side of crying UE, then in this step, callee UE can comprise calling party in information The MSISDN of UE；

The message to be instructed such as step 304, MME receive, return the paging of callee UE to MSC Status message, to notify that MSC callee UE has received page notification message and started a personal-machine Interactive program；

Step 305, MSC receive paging state message, extend the CS territory paging waiting callee UE The time of response, and according to preset strategy to the MSC return CS territory call link that calling party UE registers The called terminal ringing message i.e. ACM set up, forwards to calling party UE for MSC；

Step 306, callee UE receive CS territory page notification message, according to the CS pre-set Fallback configuration information display reminding information, performs CS Fallback flow process to ask user to be confirmed whether；

Step 307, callee UE get user input execution order i.e. interrupt current data service, Carry out the order of speech business, the selection of UE record user, and send service request information to eNB；

Step 308, eNB receive service request information, forward this service request information to MME；

Step 309, MME receive service request information, initiate CS Fallback flow process.

In the present embodiment step 303, CS Fallback configuration information can be " the most preferentially receiving calls ", So callee UE then determine when receiving CS territory page notification message can not display reminding information, and Directly confirm to perform CS Fallback flow process；CS Fallback configuration information can also be for " always asking to use Family confirms ", then callee UE then determines display reminding information when receiving CS territory page notification message, It is confirmed whether to perform CS Fallback flow process with request user；CS Fallback configuration information can also be " when UE carries out some Packet Service that should not interrupt (Online Video, game etc.), ask user Confirm ", then callee UE receives CS territory during carrying out the most interruptable Packet Service and seeks Then determine display reminding information when exhaling notification message, perform CS Fallback stream to ask user to be confirmed whether Journey；CS Fallback configuration information can also be " to the calling party UE on specific white list, the most excellent Listen before phone；Or to the calling party UE on specific blacklist, always refusal receives calls；Or i.e. Not on white list, other calling party UE the most on the blacklist, request user confirms ", then quilt The side of crying UE receives during the CS territory page notification message of the calling party UE triggering on specific white list the most true Surely can not display reminding information, and directly confirm perform CS Fallback flow process, callee UE receive Then can not display reminding during the CS territory page notification message that the calling party UE on specific blacklist triggers Information, and directly refuse CS Fallback flow process, callee UE receives other calling party UE and triggers CS territory page notification message time determine display reminding information, with ask user be confirmed whether perform CS Fallback flow process.When callee UE determines display reminding information, callee UE then returns to MME The purposes of message to be instructed such as returning is that notice MME callee UE starts a personal-machine interactive program, The user of callee UE confirms perform CS Fallback flow process or refuse CS Fallback flow process The longer time that processes may be needed could to respond the paging request of MSC.If callee UE determines permissible Not during display reminding information, callee UE the most directly confirms that performing CS Fallback flow process still refuses CS Fallback flow process, then in this step callee UE can not to MME return to waiting for indicate message and straight Connect beginning CS Fallback flow process, be not received by UE etc. message to be instructed time, MME will not The paging state message of callee UE is returned to MSC.

The technical scheme of certain above-mentioned the present embodiment does not repel callee UE in the CS territory receiving MME After paging request message, when determining not display reminding information, also can disappear to MME transmission etc. is to be instructed Breath.

Similar with the embodiment of the present invention two, the present embodiment step 304 can have two kinds of executive modes: a kind of Return the paging state message of callee UE immediately to MSC for message to be instructed such as MME receive； After another kind is for message to be instructed such as MME receive, start an intervalometer, surpass at this intervalometer Return the paging state message of callee UE time after again to MSC, here is omitted.

Compared with the embodiment of the present invention two, the MME in the present embodiment is returning UE paging shape to MSC Before state message, consulted with callee UE, i.e. MME is according to the callee UE institute got Feedback etc. message to be instructed, if MME determine callee UE by start man-machine interaction program with to After user is confirmed whether to perform CS Fallback flow process, MME returns callee UE's to MSC again Paging state message, to indicate the relevant information of the paging state of callee UE；If MME determine by The side of crying UE will not start man-machine interaction program with to user be confirmed whether perform CS Fallback flow process it After, MSC then waits normal page response by normal flow process, it is not necessary to extend page response etc. Treat the time, or perform to respond to calling party in advance the process step of called terminal ringing message.

The UE reception being currently in connection status in E-UTRAN survey is mentioned in the embodiment of the present invention three After the CS territory page notification message that MME sends, can be according to configuration thereon and Packet Service shape State determines the need for display reminding information asks user to be confirmed whether to need to perform CS Fallback flow process, but The problem so introducing a Consumer's Experience, if the user of UE confirms to perform CS Fallback flow process, According to the experience of existing CS territory phone, user will be considered that and had picked up phone.But, some CS territory Supplementary service, the user of callee UE can not only telephone number with calling party UE determine whether Answer this phone, such as: Call Forwarding (Call Forwarding) business, call redirection (Call Deflection) business etc..

In Call Forwarding services, the user A of calling party UE calls user B, and user B is (front Turn side) business datum be set to Call Forwarding to user C, then show the UE of user C on carries Show that information is the calling user information i.e. telephone number of user A.But possible user C is ready listening user The phone of A, but it is unwilling to answer the phone of any user's B forward, if at request called subscriber C Confirm must confirm directly to answer this phone during CS Fallback, then just deprived called subscriber in calling Forward-shifting service selects the right answered according to forward side's information.In call deflection service, calling party UE User A call user B, user B after UE ring, by inputting user on UE The MSISDN of C is by this Call Forwarding to user C.Call redirection with the difference of Call Forwarding services is: Call deflection service needs intermediate user B to input the phone of end user C before selecting " acceptance " call Number, and confirm to perform call redirection；Call deflection service from user A arrive user B be one general Logical calling, therefore MSC cannot judge before user B operates whether user B can initiate calling and turn To operation.Owing to call redirection operation must interact between UE and MSC, if please be called The user of side UE confirms to provide only " answering " and " refusal " this audio call two during CS Fallback Option of operation, it is impossible to provide call redirection option of operation, then just deprive under CS Fallback scheme User uses the right of call deflection service.

The schematic flow sheet of the paging processing method that Fig. 4 provides for the embodiment of the present invention four, in the present embodiment Callee UE currently by E-UTRAN access EPC, callee UE registration MME with called The MSC that side's UE registration is bought has passed through SGs interface and has set up association, and as shown in Figure 4, the present embodiment can To comprise the following steps:

The MSC of step 401, callee UE registration receives the IAM, this IAM that calling party sends Carrying the MSISDN of callee UE in message, MSC is according to callee entrained in IAM message The MSISDN of UE searches the context of callee UE, obtains IMSI corresponding to callee UE, logical Cross the MME transmission paging request message that SGs interface is registered, this paging request message to callee UE In carry the IMSI of callee UE, and type of service mark.

Type of service therein mark can be to represent normal voice calls and various concrete supplementary industry The types such as business are such as: Call Forwarding services etc., notice whether called subscriber initiates call redirection as previously mentioned Business, depends entirely on the operation of called subscriber, now processes as an ordinary call before MSC. Therefore this type of service mark will not represent call deflection service.In follow-up flow process, callee UE According to the concrete type of service represented by above-mentioned type of service mark, and can believe according to the configuration of self Breath, determines and the need of at callee UE, this type of service is switched to rear flank, CS territory one, again show Information, to ask the user of callee UE to be confirmed whether to receive calls.

This type of service mark can also directly one indicate whether to need display reminding information again Mark, i.e., after the relevant informations such as the particular type of business are judged by MSC, directly indicate whether needs Being switched to rear flank, CS territory one at callee UE, display reminding information again, to ask the use of callee UE Family is confirmed whether to receive calls, such as: to normal voice calls, generates an expression and is not required to again point out Mark；Business to Call Forwarding type, generates the mark that an expression needs again to point out.

Step 402, MME receive paging request message, according to quilt entrained in paging request message The IMSI of the side of crying UE searches the context of callee UE, according to record in the context of callee UE Condition adjudgement callee UE when being in connection status, sent to callee UE by NAS layer message CS territory page notification message.

If the paging request message that MSC is sent in step 401 carries the mark of calling party UE The relevant information of the calling such as information, type of service mark, i.e. MME obtains calling party UE from MSC Identification information, the relevant information of the calling such as type of service mark, then in this step, MME can be by upper State relevant information to be included in the page notification message of CS territory；

Step 403, MME return the paging state message of callee UE to MSC, to notify MSC Callee UE has received page notification message and has started a personal-machine interactive program.

Wherein, MME can return the paging state message of callee UE, MME immediately to MSC Can also with callee UE consult after, further according to callee UE returned etc. message to be instructed to MSC Return the paging state message of callee UE, respectively as described in above-described embodiment two and embodiment three, this Embodiment repeats no more；

Step 404, MSC receive paging state message, extend the CS territory paging waiting callee UE The time of response, and return, to calling party, the called terminal ringing that CS territory call link is set up according to preset strategy Message i.e. ACM；

Step 405, callee UE receive CS territory page notification message, according to the CS pre-set Type of service mark display entrained in Fallback configuration information and CS territory page notification message the One information, performs CS Fallback flow process to ask user to be confirmed whether, and according to this type of service Mark determines the first information content, such as:

When the type of service in the page notification message of CS territory is for need not reaffirm, then callee UE In the first shown information, before answering call, user does not also needs to the content reaffirmed, I.e. information is confirmed whether directly to answer calling for request user, such as, " have 13XXXXXXXXX To your calling, if interrupt current XXXX Packet Service, directly answer this calling？", it is provided that " acceptance ", " refusal " can be included, it is also possible to include " call redirection " to the option of operation of its user.

When the type of service in the page notification message of CS territory is reaffirmed for needs, then callee UE institute First information of display also needs to the content reaffirmed, i.e. containing user before answering call Information is confirmed whether to be ready to interrupt current group business for request user, is switched to CS territory, but not It is directly to confirm to answer this calling, but needs its user to reaffirm after being switched to CS territory, such as: " having 13XXXXXXXXX to your phone, this call is forward type service, it may be necessary to you connect Being confirmed whether to answer this calling after receiving call information, if interrupt current XXXX Packet Service, receiving should Call information？", it is provided that " acceptance ", " refusal " can be included to the option of operation of its user；
