Fig. 2 is the business process map during as the callee according to the commentaries on classics network users of registering the net switching and number changing informing business of another embodiment of the present invention.
Embodiment
In user's information transmission method for net switching and number changing of the present invention, user's net switching and number changing information transfer service is used as the intelligent wireless network service that is independent of the reciprocal exchange of business in the new mobile radio communication and handles, therefore, in new mobile radio communication, the user who need to transmit net switching and number changing information must be signed up as the intelligent wireless network users among the attaching position register HLR under it, and under it corresponding relation between interior telephone number of its former mobile radio communication of service control point (SCP) stored (being designated hereinafter simply as former net) and the interior telephone number of the new mobile radio communication that changes over to (being designated hereinafter simply as new net) with and be user's net switching and number changing information transfer service logical types that different caller rs numbers are selected.In addition, in user's former mobile radio communication, it must be registered as according to the Call Forwarding user who goes to telephone number in the new mobile radio communication before the telephone number in the former mobile radio communication.
Thus, as calling party when telephone number makes a call as dialing numbers in the former net with the callee, change to handle before this calling is at first done in former net and continue to new net, then in new net, handle telephone number in the new net of the callee as transferred number that obtains by HLR under the callee according to changeing before in the former net, this calling is identified as the intelligent wireless network service and indicates under in return the GMSC (gateway mobile switching center) GMSC/SSP of service point SSP transfers business to callee the service control point (SCP) to handle.SCP is the Core Feature parts of intelligent network, and in the present invention, it starts corresponding user's net switching and number changing information transfer service logic according to caller rs number, dialing numbers and the transferred number that GMSC/SSP in the new net provides.Particularly, SCP at first finds telephone number in the corresponding former net of callee according to transferred number, because the former net telephone number that finds is consistent with dialing numbers, SCP determines that this calling belongs to user's net switching and number changing information transfer service, starts corresponding user's net switching and number changing information transfer service according to the aforementioned predetermined service logic type of selecting for different caller rs numbers subsequently.
Concrete user's net switching and number changing information transfer service logical type is below described.A kind of user's net switching and number changing information transfer service logic is at first to call ip intelligent peripherals IP resource when SCP determines that calling belongs to user's net switching and number changing information transfer service, play the changed number notification voice messaging to the calling party, and then between calling party and callee, set up call link.
Another kind of user's net switching and number changing information transfer service logic is at first to send message to the MC of short message service center when SCP determines that calling belongs to user's net switching and number changing information transfer service, indicate it to send the changed number notification short message, and then between calling party and callee, set up call link to the calling party.
Also have a kind of user's net switching and number changing information transfer service logic to set certain changed number notification transitional period (promptly user's net switching and number changing is professional to be transmitted the period of ending to stopping from user's net switching and number changing), therefore have the timeliness function.When SCP determines that calling belongs to user's net switching and number changing information transfer service, it at first judges current dialing constantly whether in this period, whether the i.e. number of the changing transitional period expires, if do not expire as yet, then send callee's net switching and number changing notice, and then between calling party and callee, set up call link to the calling party; Otherwise, calling is considered as infecctive call handles accordingly.In this service logic, the number of the changing transitional period both can also can oneself be set by the user as required by default.
In above-mentioned service logic type, the transmission of changed number notification information is not optionally to the calling party, in other words, and all chosen identical service logic type of all caller rs numbers.In following a kind of user's net switching and number changing information transfer service logic, increased the selection function of caller rs number.
In this service logic, the net switching and number changing user can set four kinds of modes that send the net switching and number changing information for caller rs number, promptly not the restriction of originating calls mode, allow registration caller send mode, allow registration caller send mode and allow the caller mode not.When SCP determine to call out when belonging to user's net switching and number changing information transfer service, if what set is restriction of originating calls mode not, then to all calling partys all without stint send the net switching and number changing announcement information; If what set is to allow registration caller send mode, then the caller rs number to callee's registration will not send the net switching and number changing announcement information and directly set up call link between calling party and callee; If what set is to allow registering not send mode of caller, then the caller rs number that the callee is registered neither sends the net switching and number changing announcement information and does not also set up call link between calling party and callee; If what set is to allow the caller mode, then the calling party to callee's registration will send the net switching and number changing announcement information and set up call link between calling party and callee.
It should be understood that the impossible exhaustive all service logic types of foregoing description, so it only has illustrative nature and can not be interpreted as limitation of the invention.In addition, therefore, the present invention is based on the principle of wireless intelligent network process user net switching and number changing information transfer service and the type of former net and new net has nothing to do, in other words, former net here and new net can be various types of mobile radio communications, for example global mobile system GSM net and code division multiple access CDMA net.
Below to change net CDMA network users with the callee from GSM net be example, by accompanying drawing preferred embodiment of the present invention is described, wherein, caller rs number in embodiment illustrated in fig. 1 is registered as the caller mode that allows by the callee in SCP, the caller rs number in embodiment illustrated in fig. 2 is registered as permission to registration caller send mode not by the callee in SCP.
As shown in Figure 1, as calling party when telephone number starts calling as dialing numbers in GSM net with the callee, at first handle calling out preceding commentaries on classics of work by the GMSC (gateway mobile switching center) GMSCg in the GSM net, promptly, obtain the telephone number (be transferred number) of callee in the CDMA net according to dialing numbers, GMSCg is routed to the GMSC (gateway mobile switching center) GMSC/SSP that CDMA net in have service control point function with the callee for the Call Forwarding Unconditional calling of changeing network users by sending IAI message subsequently.Comprise caller rs number, transferred number (promptly changeing network users number in CDMA nets) and dialing numbers (promptly changeing number in the network users GSM net) in the above-mentioned IAI message, and sending elsewhere the calling position indication in this message is sent calling elsewhere effectively.GMSC/SSP receives IAI message to GMSCg loopback ACM message with affirmation after receiving IAI message.
Meanwhile, GMSC/SSP sends the LOCREQ message that position requests comprises callee's telephone number or transferred number in the CDMA net to the callee at the HLR that CDMA net is belonged to, and asks this HLR to return relevant callee's relevant information.HLR then responds to LOCREQ message, confirm that this business belongs to the intelligent wireless network service, therefore position requests from affiliated SCP address to GMSC/SSP that return the called flow list of triggers inventory that is included as callee's configuration and the locreq message of receiveing the response, wherein, the called flow trigger comprises senior terminating trigger Advanced_Termination and location trigger Location.
After GMSC/SSP receives locreq message, trigger senior trigger Advanced_Termination, SCP address in message sends information analysis ANALYZD message, in the parameter that this message comprised, CallingPartyNumberDigits1 is a caller rs number, RedirectionNumberDigits is dialing numbers (callee's a GSM number), and Digits (Dialed) is callee's MDN (being CDMA network No. sign indicating number or transferred number).
SCP is after receiving information analysis ANALYZD message, find callee's GSM number according to callee's MDN, because the callee has registered the net switching and number changing information transfer service in SCP, so its GSM number is consistent with dialing numbers in the information analysis ANALYZD message, SCP confirms that thus the intelligent network business that GMSC/SSP reports is the net switching and number changing information transfer service and starts net switching and number changing information transfer service logic.
In the present embodiment, caller rs number is registered as the caller mode that allows by the callee in SCP.If therefore comprise the service logic that sends the net switching and number changing short message to the calling party, then SCP sends the point-to-point short message SMDPP that comprises net switching and number changing information to the MC of short message service center.MC returns response message smdpp to SCP after receiving SMDPP message, and sends SMS message to the calling party by short messaging gateway.
If comprise the service logic that sends the net switching and number changing voice messaging to the calling party, then SCP sends request resource message SEIZRES to ip intelligent peripherals IP.IP responds after receiving SEIZRES message, returns the seizres message that comprises its interim local telephone number TLDN.SCP puts into connection resource CONNRES message with the TLDN number of IP as parameter and sends to GMSC/SSP, and speech channel CALL SETUP is set up in indication between GMSC/SSP and IP.After speech channel was set up, IP sent indication request message INSTREQ to SCP, and request SCP gives the playback indication.And SCP sends playback Indication message SRFDIR to IP in view of the above, and indication IP plays the voice ANNOUCEMENT that comprises net switching and number changing information through GMSC/SSP and GMSCg to the calling party.When the IP playback finished, no matter playback success or failure were all returned srfdir message to SCP.If no longer need playback, then SCP sends instrreq message to IP, and indication stops playback.After playback finished, SCP sent information analysis analyzd message to GMSC/SSP, and parameter DMH_ServiceID=133 is set, and the business of indicating current activation is the changed number notification business.Subsequently, IP will discharge the traffic resource CALL RELEASE with GMSC/SSP.
Because caller rs number is for allowing the caller mode, therefore after user's net switching and number changing information transfer service is finished, be after the link circuit resource of IP and GMSC/SSP discharges, GMSC/SSP triggers the location trigger Location that aforementioned HLR provides, send LOCREQ message to HLR, callee's current location is searched in request.After HLR receives LOCREQ message, the moving exchanging center MSC with service control point function under callee's current location/SSP sends route request information ROUTREQ, and this MSC/SSP receives after the ROUTREQ message to the callee and distributes a TLDN number and return to HLR by the route requests routreq of receiveing the response.HLR is sent to GMSC/SSP by the position requests locreq of receiveing the response with the TLDN number again.And GMSC/SSP utilizes this TLDN number and the residing MSC/SSP of callee to set up speech path channel.When callee's off-hook was replied, GMSCg received the ANC message that this MSC/SSP sends, and realized conversation thus between calling party and callee.And when callee's on-hook, the calling between the caller both sides is released.
As shown in Figure 2, as calling party when telephone number starts calling as dialing numbers in GSM net with the callee, with embodiment illustrated in fig. 1 identical, after the preceding commentaries on classics of the GMSC (gateway mobile switching center) GMSCg of calling in the GSM net is handled, be routed to the GMSC (gateway mobile switching center) GMSC/SSP that has the service control point function in the CDMA net by IAI message.Also comprise caller rs number, transferred number (promptly changeing network users number in CDMA nets) and dialing numbers (promptly changeing number in the network users GSM net) in the above-mentioned IAI message, and sending elsewhere the calling position indication in this message is sent calling elsewhere effectively.GMSC/SSP receives IAI message to GMSCg loopback ACM message with affirmation after receiving IAI message.
Meanwhile, GMSC/SSP sends the LOCREQ message that position requests comprises callee's telephone number or transferred number in the CDMA net to the callee at the HLR that CDMA net is belonged to, and asks this HLR to return relevant callee's relevant information.HLR then responds to LOCREQ message, confirm that this business belongs to the intelligent wireless network service, therefore position requests from affiliated SCP address to GMSC/SSP that return the called flow list of triggers inventory that is included as callee's configuration and the locreq message of receiveing the response, wherein, the called flow trigger comprises senior terminating trigger Advanced_Termination and location trigger Location.
After GMSC/SSP receives locreq message, trigger senior trigger Advanced_Termination, SCP address in message sends information analysis ANALYZD message, in the parameter that this message comprised, CallingPartyNumberDigits1 is a caller rs number, RedirectionNumberDigits is dialing numbers (callee's a GSM number), and Digits (Dialed) is callee's MDN (being CDMA network No. sign indicating number or transferred number).
SCP is after receiving information analysis ANALYZD message, find callee's GSM number according to callee's MDN, because the callee has registered the net switching and number changing information transfer service in SCP, so its GSM number is consistent with dialing numbers in the information analysis ANALYZD message, SCP confirms that thus the intelligent network business that GMSC/SSP reports is the net switching and number changing information transfer service and starts net switching and number changing information transfer service logic.
In the present embodiment, caller rs number is registered as permission to registration caller send mode not by the callee in SCP, so SCP indication IP sends the information that can't connect to the calling party.
To send by voice suggestion can't connection information be example, and SCP will send request resource message SEIZRES to IP.IP responds after receiving SEIZRES message, returns the seizres message that comprises its TLDN number.SCP puts into connection resource CONNRES message with the TLDN of IP as parameter and sends to GMSC/SSP, and speech channel CALL SETUP is set up in indication between GMSC/SSP and IP.After speech channel was set up, IP sent indication request message INSTREQ to SCP, and request SCP gives the playback indication.And SCP sends playback Indication message SRFDIR to IP in view of the above, and indication IP plays the voice (ANNOUCEMENT) that comprise the information of can't connecting through GMSC/SSP and GMSCg to the calling party.When the IP playback finished, no matter playback success or failure were all returned srfdir message to SCP.If no longer need playback, then SCP sends instrreq message to IP, and indication stops playback.After playback finished, SCP sent analyzd message to GMSC/SSP, and parameter A ctionCode=2 is set, and indication GMSC/SSP discharges the traffic resource CALL RELEASE with IP.At last, calling party's calling is released CALL RELEASE.
