Step 3, end.
Embodiment 5
This embodiment has described at the PC software terminal and has taken over mobile telephone registration under the state of IMS and CS core net based on embodiment 1 described network, the process when the PC software terminal initiatively makes a call, and concrete steps are as follows:
Step 1, user can use PC keyboard or cell phone keyboard to dial called number (if adopt the cell phone keyboard dialing numbers, mobile phone can send dialing information to the PC software terminal).
Step 2, PC software terminal make a call to IMS core according to IMS standard call flow process.
Step 3, after the S-CSCF among the IMS core receives INVITE, the caller iFC rule according to this user contracts is triggered to " AS+MSC/VLR " network element.Follow-up flow process is handled (this " AS+MSC/VLR " network element is the AS of standard at the IMS network, is the MSC/VLR of standard at the GSM network) according to 3GPP 23.018 standards.
Step 4, enter ring and talking state when this calling, the user can select the receiver of mobile phone or PC and microphone converse (if the user uses mobile phone communication, speech transmits by the transmission channel between mobile phone and PC software terminal).
Step 5, flow process finish.
Embodiment 6
This embodiment has described at the PC software terminal and has taken over mobile telephone registration under the state of IMS and CS core net based on embodiment 1 described network, the processing procedure when this phone number is called, and concrete steps are as follows:
Step 1, other users dial this user's phone number, call out the network (following supposition home network is GSM, in fact can be any cell communication networks such as UMTS, CDMA, TD-SCDMA) that is routed to this phone number ownership.
GMSC in step 2, the GSM net inquires about route to HLR.Because this phone number is taken over mobile phone by the PC software terminal, be registered to " AS+MSC/VLR " network element of IMS, this network element is the MSC/VLR of the current visit of user at HLR, therefore HLR obtains roaming number to this " AS+MSC/VLR " network element, the flow process of obtaining of this roaming number is followed the GSM network requirement, i.e. the requirement of 3GPP 29.002 standards.
Step 3, HLR return to GMSC to the roaming number that gets access to, and GMSC routes calls to " AS+MSC/VLR " network element.
Step 4, " AS+MSC/VLR " network element receive that GMSC sends go into to call for ask after, to the S-CSCF request of making a call, follow-up flow process is followed 3GPP 24.229 standards by ISC interface, calls out and is routed to the PC software terminal by the IMS network.
After step 5, PC software terminal are received calling, ringing tone (when adopting the mode of cell-phone bell, requiring the PC software terminal to give mobile phone ring sound by interface channel) can sent on PC or the mobile phone.
Step 6, this user can reply by cell phone keyboard or PC software terminal off-hook.Divide 2 kinds of situations: if reply by the cell phone keyboard off-hook, the receiver and the microphone of the follow-up use mobile phone of user are conversed, and voice can transmit between mobile phone and PC software terminal by interface channel.If reply by PC software terminal off-hook, microphone and the loud speaker of the follow-up use of user PC are conversed.
Step 7, end.
Embodiment 7
This embodiment has described at the PC software terminal and has taken over mobile telephone registration under the state of IMS and CS core net based on embodiment 1 described network, and this user sends the process of note/multimedia message, specifically may further comprise the steps:
Step 1, user send note/multimedia message by the PC software terminal, and this note/multimedia message is packaged into the MESSAGE message of IMS, is sent to the S-CSCF of IMS core net.
After step 2, S-CSCF receive MESSAGE message,, be triggered to " AS+MSC/VLR " network element by ISC interface according to the iFC rule.
Step 3, " AS+MSC/VLR " network element are received the MESSAGE message that ISC interface sends, and according to 3GPP 29.002 standards, the MESSAGE message conversion are become MAP message, are sent to sms center (SC).
After step 4, sms center are received this note request, follow-uply finish the note transmission flow, note is sent to callee side according to 3GPP 29.002.
Step 5, end.
Embodiment 8
This embodiment has described at the PC software terminal and has taken over mobile telephone registration under the state of IMS and CS core net based on embodiment 1 described network, and this user receives the process of note/multimedia message, specifically may further comprise the steps:
Step 1, other users send note/multimedia message to this subscriber phone number, this note/multimedia message is sent to the home network (following supposition home network is GSM, in fact can be any cell communication networks such as UMTS, CDMA, TD-SCDMA) at this user place.
Note/MMS gateway in step 2, the GSM net is to HLR short message enquiry route.Because this phone number is taken over mobile phone by the PC software terminal, be registered to " AS+MSC/VLR " network element of IMS, this network element is the MSC/VLR of the current visit of user at HLR, so HLR returns the address of the current roaming place of this user " AS+MSC/VLR " to note/MMS gateway.
Step 3, Short Message Service Gateway send note/multimedia message to " AS+MSC/VLR " network element.
After step 4, " AS+MSC/VLR " network element are received note/multimedia message requests, convert MESSAGE message to, send to S-CSCF by ISC interface, follow-up flow process is followed the IMS standard, and MESSAGE is routed to the PC software terminal by the IMS network.
After step 5, PC software terminal are received MESSAGE message, take out the note/MMS content of this message encapsulation, present to the user; Perhaps, also can send this message to mobile phone, and present to the user by mobile phone and watch by the transmission channel between mobile phone and the PC software terminal.
Step 6, end.
The scheme that provides by the embodiment of the invention, can make the user can continue to use the business of portable terminal by Internet in the area that does not have signal, utilize IP Access Network and IMS technology, allow the user select portable terminal or IMS terminal to use phone, note, MMS.The user is no matter using portable terminal still is the IMS terminal, and external number all is this mobile terminal number, the terminal type that other users can this user of perception.Thereby realize that mobile phone users is in the place of having ready conditions use IMS terminal, use the IMS terminal as far as possible, the portable terminal traffic is transferred in the fixed broadband as far as possible, thereby reduced electric quantity consumption, the wireless radiation of portable terminal, and can reduce the wireless base station investment of operator.
Obviously, those skilled in the art should be understood that, above-mentioned each module of the present invention or each step can realize with the general calculation device, they can concentrate on the single calculation element, perhaps be distributed on the network that a plurality of calculation element forms, alternatively, they can be realized with the executable program code of calculation element, thereby, they can be stored in the storage device and carry out by calculation element, and in some cases, can carry out step shown or that describe with the order that is different from herein, perhaps they are made into each integrated circuit modules respectively, perhaps a plurality of modules in them or step are made into the single integrated circuit module and realize.Like this, the present invention is not restricted to any specific hardware and software combination.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
