Fig. 2 registers the schematic flow sheet of business association for the VOLTE of the embodiment of the present invention, as shown in Figure 2：
Before VOLTE registrations, user can carry out EPC attachment flows, and S1-MME interface passes through Attach
Request message initiates attach request to MME, in the message comprising user IMSI, TAC, ECI, IMEI,
Type of attachment (EPS attach, combined EPS/IMSI attach), UE whether support eSRVCC switching,
The information such as PCO (whether setting up IMS signaling bears), IP address type, IMS APN；On S6A interfaces,
MME is interacted with HSS, is authenticated by AIR/AIA, wherein important related information is user
IMSI, the insertion of HSS user data is realized also by Location Update Request/ACK, wherein heavy
Wanting information includes STN-SR, C-Number；On Gx interfaces, SGW passes through Credit Control Request
Message request PCRF sets up IMS default bearings, including user IMSI, address information, ECI information, End
To set up process signalling correlated available for this by End Identifier；Eventually through S1-MME interface Attach
Accept message completes attachment flow, including the UE IP of the MME S-TMSI distributed and SGW distribution
Address, SBC addresses, dns address and correlation IMS information；Whole attachment and default bearing set up process
It can be carried out returning according to demand in efficient association, record according to IMSI, End to End Identifier marks
Fill out the information such as Subscriber Number, APN types, IP address, UE abilities.
EPC attachments are completed, are being set up after IMS default bearings, VOLTE user initiates register flow path, Gm
Interface initiates IMS registration flow by Register message, carries IMPU (IMSI is shifted onto out), UE IPv6
Address, ECI, Call ID, P-Charging-Vector；STN-SR is carried in Mw, Register message
Number；I-CSCF obtains S-CSCF information, message by the UAR/UAA message of Cx interface to HSS
Carry IMPU and Register marks；S-CSCF obtains authentication letter by MAR/MAA message to HSS
Breath, message carries the information such as IMPU and S-CSCF name；Pass through Mw for initial registration S-CSCF
Interface re-starts authentication to issuing 401Unauthorized message calls terminals, carry authentication parameter and
The information such as IMPU；UE resends Register message and authenticated；HSS passes through Cx interface
SAR/SAA message returns to the IMPU (MSISDN is derived), iFC, contract message, Charging-Address of user
Deng；S-CSCF initiates third party registration messages by ISC interface to AS, carries IMPU (MSISDN
Shift onto out) and complete log-on message；By Sh interface between AS and HSS, UDR/UDA message requests and
Return to the information, PUR/PUA information updating STN-SR parameters such as user data, eSRVCC abilities；AS
ATU-STI and MSISDN (C-NUMBER) number are issued by MESSAGE message in ISC interface
Code；The STN-SR parameters that HSS passes through IDR/IDA information updatings MME；Last UE passes through Subscribe
The state of message subscribing oneself, carries UE numbers and end message.Whole registration process can according to IMPU,
MSISDN, Call ID, P-Charging-Vector are associated, and wherein Diameter process can be with
End to End Identifier marks can also be added to be associated, the lifting association degree of accuracy.
VOLTE completely registers business association Main Basiss, by MSISDN, IMSI, IMPU, Call ID,
P-Charging-Vector, End to End Identifier marks are associated, and registration can be returned according to demand
Fill out IMEI, terminal capability, STN-SR, ATU-STI, IP address, network element address etc..
For VOLTE call business, according to VOLTE user's registration, network is obstructed can be divided into four kinds of scenes：
Calling and called VOLTE by LTE network with being called per family, and caller VOLTE user is in LTE network
Calling is registered in the VOLTE user of CS networks, and caller VOLTE user is registered in CS calling networks
The VOLTE user of LTE network, caller VOLTE user calls CSFB user in LTE network；Simultaneously
VOLTE user also needs to consider eSRVCC handoff scenarios in LTE network calling.Without loss of generality, originally
Invention illustrates calling and called VOLTE with carrying out call scenario business association, VOLTE by LTE network per family
User is in LTE network calling CSFB user scene service association and eSRVCC handoff associations.
The schematic flow sheet that Fig. 3 associates for the VOLTE call business of the embodiment of the present invention, as shown in Figure 3：
Calling UE sends Invite message by Gm to SBC, carries the IMPU (SIP of calling subscribe：
+ 86 forms or TEL:+ 86 forms), in called IMPU, Authorization field with caller IMPI,
The letters such as ECI, access SBC addresses, UE IP address, Call ID, P-Charging-Vector, conversation type
Breath；SBC asks voice dedicated bearer and QoS to configure by AAR/AAA in Rx interface to PCRF,
Carry the information such as caller MSISDN and End to End Identifier marks；PCRF passes through in Gx interfaces
RAR/RAA message calls SGW sets up dedicated bearer and QoS guarantee, carries UE IP address, End to
End Identifier identification informations；After the completion of dedicated bearer is set up, SBC connects Invite message by Mw
Mouth delivers to I/S-CSCF, and the latter triggers AS by Invite message one by one again；
AS carries out number consolidation, the called number of TEL URI forms is switched into SIP URI forms, simultaneously
Trigger compensation business；S-CSCF is obtained after called I-CSCF, and Invite message is routed into callee side
I-CSCF, carries the information such as calling and called IMPU, Call ID, P-Charging-Vector, conversation type；I-CSCF
Called S-CSCF is obtained to HSS by LIR/LIA message, called IMPU, End to End are carried
The information such as Identifier marks；Callee side S-CSCF receives the signing information that Invite obtained according to HSS and touched
Send out AS；AS is completed after called domain choosing and supplementary service triggering, by Invite message back to S-CSCF, S-CSCF
Invite is issued to SBC by Mw；Called SBC requires to set up as caller to PCRF
Voice dedicated bearer, represents to continue while replying 183Session Progress message to calling UE,
The information such as calling and called IMPU, Call ID, P-Charging-Vector are carried, Calling Side is responded PRACK and disappeared
Breath is called as 183 acknowledgement messagings and replys 200OK message；Calling Side initiates Update message and called
Resource negotiation is carried out, negotiation finishes rear callee side can 200OK；Called UE starts ring, loopback after connecting
180Ringing message；Callee side returns 200OK after receiving calls；During one side's on-hook, disappeared by BYE
Breath terminates call, while the release of the carrying including two side SBC to PCC；
Calling and called VOLTE is passed through with call scenario association Main Basiss are carried out by LTE network per family
MSISDN(C-NUMBER)、IMPU、Call ID、P-Charging-Vector、End to End Identifier
Mark, UE IP address be associated, call record can backfill according to demand IMEI, terminal capability, STN-SR,
ATU-STI, network element address, conversation type etc..
VOLTE user LTE network call CSFB user's scene service correlating method Calling Side with it is above-mentioned
Unanimously, the main distinction is the association of callee side, and flow is as shown in Figure 4：
AS carries out asking CSRN roaming numbers to called place HSS by UDR/UDA message after the choosing of domain,
Carry called IMPU, CSRN, End to End Identifier marks；S-CSCF by Mg to
MGCF sends Invite message, carry the IMPU of caller, called MSRN, P-Charging-Vector,
The information such as Call ID；MGCF initiates IAM message to the MSC at called place, carry caller MSISDN,
