For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with accompanying drawing.
Referring to shown in Figure 2, realize that system of the present invention comprises circuit domain 211, packet domain 212, PDSN206, AN 205, MSC (plus) 210.Wherein, circuit domain 211 comprises SMC 204, HLR 203, MSC/VLR 202, BSS 201, and packet domain 212 comprises IMS SMC 209, HSS 208, S-CSCF207.And MSC/VLR 202 links to each other by MSC (plus) 210 with S-CSCF 207.In circuit domain, the function of MSC (plus) 210 is identical with common MSC, and in packet domain, the function of MSC (plus) 210 is identical with the function of AS that can terminating call and BCCF/MGW.
Based on above-mentioned network frame, when MS carries out business in circuit domain, MS can send SMS message by the multimedia short message center of short message service center in packet domain of circuit domain, utilize this short message to represent that this MS is in circuit domain, multimedia short message center this MS of notice MSC (plus) is in circuit domain, after MSC (plus) received this notice, the trigger for download device was to S-CSCF again.After this, when S-CSCF need be when this MA sends packet traffic requests, S-CSCF utilizes trigger that this calling is triggered on the MSC (plus).
When MS carries out business in packet domain, monitoring circuit territory network simultaneously, can in packet domain, judge the beep-page message that whether has in the electric territory oneself, but the business in the ongoing packet domain of MS requires than higher implementation, such as: the VT business, may be because MS own resource deficiency, MS can't monitor circuit-domain network, at this moment, need the process of MS to a location registers of circuit domain initiation, circuit domain writes down this MS and carries out business in packet domain.When circuit-domain network has the paging request of called this MS of being, the MSC of circuit domain can route the call to MSC (plus), MSC (plus) can send the VOIP calling by this MS in packet domain, also can use the CSI service mode to notify user's return circuit territory, afterwards, MS answers the call in circuit domain.
Referring to shown in Figure 3, in the present embodiment, when MS carries out business in circuit domain, realize that the detailed process of reception packet switch domain service is as follows:
Step 301:MS has carried out location registers at MSC/VLR in circuit domain by BSS, and this MS carries out business in circuit domain.Here, the business that this MS carries out in circuit domain can be this MS as caller, the called speech business of carrying out, short message services etc. also can just have been carried out location registers in circuit domain, connect but carry out business.
Step 302: at this moment, if MS need carry out packet switch domain service, this MS sends SMS message to circuit domain sms center (SMC), utilizes this note to represent that this MS carries out business in circuit domain.
Step 303:SMC should short forwards to IMS SMC.
Step 304:IMS SMC notifies MSC (plus).
In actual mechanical process, in order to realize above-mentioned steps 302~304, can set in advance a specific identifier, this sign can be MSC (plus) address, can be a particular number, also can be that specific character string is formed, this character string can be numeral, English alphabet with and combination etc., and sign placed the position of this short message destination Mobile Station International ISDN Number, like this, when short message service center receives that destination Mobile Station International ISDN Number is the short message of above-mentioned particular number, this short message directly is transmitted to IMS SMC.The destination Mobile Station International ISDN Number that IMS SMC identifies this short message is predefined specific identifier, and the transmitting terminal number notifying of this short message is given MSC (plus).Here, for the SMC in the circuit domain and the IMS SMC in the packet domain can identify specific identifier, so can above-mentioned specific identifier be set at SMC and IMS SMC, after SMC and IMS SMC receive short message, as long as determine sign in the position of making an appointment, such as the destination Mobile Station International ISDN Number position, whether with the sign that self is provided with consistent getting final product whether, if it is consistent, then thinking needs notice MSC (plus) to download sFC for the MS of the transmitting terminal number correspondence of this short message, otherwise, think a common short message, transmit processing normally.
And in above-mentioned steps 304, IMS SMC can pass through Session Initiation Protocol, and promptly SUBSCRIBE mechanism is notified MSC (plus), also can notify MSC (plus) by alternate manner.
Step 305:MSC (plus) trigger for download device sFC to S-CSCF, and the Subscriber Number that this trigger sFC triggers is the Subscriber Number of the transmitting terminal of above-mentioned short message.
Step 306: when S-CSCF need be corresponding with Subscriber Number described in the step 305 MS when carrying out packet switch domain service, then utilize the calling that this sFC should the business correspondence to be triggered on the MSC (plus), MSC (plus) initiates audio call to circuit domain again.
Here, calling is triggered to comprises two kinds of situations on the MSC (plus).First kind: packet domain is called out and can be used circuit domain to carry, and as VOIP, at this moment, MSC (plus) is equivalent to a common MSC; Second kind: when the packet domain calling can't use circuit domain to carry, as VT, MSC (plus) sends notice to IMS MSC, the sms center interface protocol that IMS MSC uses standard sends the short message of certain special format of appointing to SMC, and SMC is transmitted to the user to the note of this special format.After the user receives this short message, according to the calling identification in the note, as predetermined in advance a certain particular number, and information such as type of service, determine whether to break the current business call accepted, if the user determines to accept, then send and reply short message and represent receipt of call, the connection in the current circuit domain of breaking then forwards packet domain to, according to the MSC in the short message (plus) address and calling ID, notice MSC (plus) MS has inserted packet field network, and MSC (plus) initiates redirect to S-CSCF, and S-CSCF is handed down to this MS to call request, after this, this MS can carry out the business in the packet domain.
The foregoing description has been set forth when MS carries out business in circuit domain, receives the process of packet switch domain service.This process need MS sends SMS message to packet domain, represent self carrying out the business of circuit domain, when if there is the service request of packet domain in packet domain to this MS, business can be triggered on the MSC (plus), realize the business of packet domain by circuit domain by MSC (plus).
But, if when MS carries out business in packet domain, some is different with said process, generally speaking, promptly under the situation of resource abundance, MS monitoring circuit territory network simultaneously in packet domain, determine whether to have in the circuit domain service request of paging oneself, if have, can be directly switch to and carry out business in the circuit domain, also can be to initiate the VOIP calling by MSC (plus) with professional in the circuit domain.But, MS under the situation of own resource deficiency, such as: this MS carries out video traffic in packet domain, because video traffic requires than higher real-time, MS may can't the monitoring circuit territory because own resource is not enough.At this moment, MS can carry out location registers to MSC/VLR by MSC (plus), and then the beep-page message of circuit-domain network can be handed down to this MS by packet domain.
In such scheme, for performance is considered also can set up a special sms center for two net interoperability, this sms center links to each other with HLR with the MSC of circuit domain, links to each other with MSC (plus), and MS can directly send SMS message to sending MSC (plus) by this short message service center so.
When illustrating that below in conjunction with Fig. 4 MS carries out business in packet domain, when self can't listen to circuit-domain network, this MS answered the process of the beep-page message of circuit domain.
Referring to shown in Figure 4, when MS carried out business in packet domain, when self can't listen to circuit-domain network, the detailed process of beep-page message that this MS answers circuit domain was as follows:
Step 401:MS carries out the business of packet domain in packet domain.
Step 402:MS sends position register request by AN, PDSN, S-CSCF to MSC (plus).
After step 403:MSC (plus) received this position register request, the MSC by circuit domain carried out location registers in HLR, write down this MS at HLR and carry out business in packet domain.
Step 404: when this MS of MSC paging, determine that according to the record of HLR this MS carries out business at present in packet domain.
Step 405: source end MSC uses the circuit domain routing mode of standard to route the call to MSC (plus), and MSC (plus) initiates VOIP to the user again and calls out, and by PDSN, AN calling is sent to MS.
In step 405, MSC (plus) can use the CSI service mode to notify user's return circuit territory, makes the user carry out business in circuit domain.
In flow process shown in Figure 4, if the user registers current at MSC (plus) in HLR, the short message that oriented this MS sends in circuit domain, short message service center can be forwarded to short message MSC (plus), and MSC (plus) uses the grouping short message service of standard to give MS with this short message issuing.
In a word, the above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.
