Above, only brief description is carried out to several network elements main in SRVCC, other can with reference to DESCRIPTION OF THE PRIOR ART, the application does not repeat them here.
Based on above-mentioned network system architecture figure, when UE moves to 2G/3G network from LTE network, report the measurement report of different systems axiol-ogy event to E-UTRAN after, trigger SRVCC and switch (English: Handover, abbreviation: HO).Concrete SRVCC switching flow as shown in Figure 2, comprising:
1, UE sends the measurement report of different systems axiol-ogy event to source eNodeB.
Wherein, different systems axiol-ogy event comprises B1 and B2 event.
B1 event is: different wireless access type is (English: Radio Access Type, be called for short: RAT) Reference Signal Received Power (English: Reference Signal Receiving Power, the abbreviation: RSRP) value is measured of community; The report condition of B1 event measurement report is: the RSRP value of different RAT community is higher than absolute threshold value.
B2 event is: measure the RSRP value of He Yi RAT community, Serving cell; The report condition of B2 event measurement report is: the RSRP value of Serving cell is lower than absolute threshold value 1 and the RSRP value of adjacent area is higher than absolute threshold value 2.
Wherein, different RAT community refers to that the Serving cell current with UE belongs to the adjacent area of different network formats.
2, source eNodeB is according to variable structure contorl, and judgement is initiated SRVCC and is switched to UTRAN/GERAN.
3, source eNodeB sends switching demand handover required to source MME, and identifies this and switch to SRVCC.
4, after receiving the switching demand of SRVCC, according to QoS class indication, (English: QoS Class Identifier is called for short: QCI) be separated with other PS carrying by voice bearer (QCI=1) source MME.
5, then source MME performs PS-CS changeover program.Source MME, according to the Target id select target SRVCC IWF (i.e. SRVCC IWF) carried in handover required, sends PS-CS and asks SRVCC IWF.Comprise STN-SR in PS-CS request, mobile subscriber's International Integrated Services digital network is (English: Integrated Services Digital Network, be called for short: ISDN/ public switch telephone network is (English: Public Switched Telephone Network, PSTN) number be called for short: (English: Mobile Subscriber International ISDN/PSTN number, MSISDN), the information such as MME context be called for short:.
6, after SRVCC IWF receives PS-CS handover request, send to target MSC and prepare handover request.
7, target MSC is to RNS (English: RadioNetwork Subsystem, abbreviation: RNS), i.e. target BS transmission redirect request, the request dispatching CS radio bearer resources of target UTRAN/EGRAN.
8, radio bearer resources is assigned, and target MSC sends to switch to SRVCC IWF and prepares response, distributes Handover Number.
9, SRVCC IWF uses Handover Number and target MSC to set up circuit domain bearer connection.
10, SRVCC IWF initiation session transfer process, IMS network performs Session Hand-off process, and upgrades far-end.Wherein, Session Hand-off process comprises: the SCC AS in IMS network judges whether current call state mates with UE ability, if coupling, the response sent to SRVCC IWF is 200ok, otherwise is failed OXX, represents that initial session shifts unsuccessfully.
After Session Hand-off process is finished, IMS network sends response message to SRVCC IWF.
11, SRVCC IWF performs UE access.
SRVCC IWF sends PS-CS handoff response to source MME, instruction UE access.MME sends switching command HO Command to eNodeB.
UE starts to attempt access CS network, and target BS sends to target MSC and is redirected monitoring Relocation Detect message, represents that UE has detected new channel, has possessed the condition of the new wireless channel of access, but not yet really accessed.After target MSC receives the Relocation Detect message that target BS reports, map modern transmission of MAP letter by interoffice and map the modern MAP PROCESS ACCESS SIGNALLING IND message of process access letter to SRVCC IWF.After UE successfully accesses CS network or access failure, target BS sends to target MSC and has been redirected Relocation Complete message, and notification target MSC has switched.When target MSC receives after report redirected complete Relocation Complete message, by interoffice MAP believe modern send to map to send terminate the modern MAP SEND END SIGNAL IND message of letter to SRVCC IWF.Wherein, when UE does not possess SRVCC ability, UE can not access target CS territory network.
12, after SRVCC IWF receives the response message and MAP SEND ENDSIGNAL IND (that is, represent UE handoff completion message) that IMS network sends, send PS-CS to source MME and switched response.
SRVCC IWF sends PS-CS completion notice message SRVCC PS to CS CompleteNotification message and completes to source MME, notification source MME switching.
13, source MME discharges PS dedicated bearer.
SRVCC IWF sends PS-CS completion notice message to source MME after receiving the response message and UE handoff completion message that IMS network sends.After MME receives PS-CS completion notice message, release UE is at the PS dedicated bearer of IMS network.Wherein, if initial session shifts successfully, and UE accesses successfully, then SRVCC IWF can by PS-CS completion notice message instruction handover success; If initial session transfer failure or UE access failure, then SRVCC IWF can by PS-CS completion notice message instruction handoff failure.
From above process, at objective network for after UE reserves Radio Resource, due to PS-CS handoff failure, the radio bearer resources of objective network circuit domain is caused to be wasted; And initiate after SRVCC switches at eNodeB, no matter handover success or failed MME can discharge PS dedicated bearer, can cause the problem of UE call drop/call loss like this when handoff failure.
In view of above problem, present applicant proposes a kind of control method and UE of different systems axiol-ogy event, the SRVCC ability of the IMS network that UE side is recorded according to UE, the SRVCC ability of UE self, and the call state that UE is current, support that UE is after current call state carries out SRVCC switching in the SRVCC ability of UE and IMS network of determining, the measurement report of the different systems axiol-ogy event meeting report condition is just reported to eNodeB, trigger eNodeB and send SRVCC switching, thus when the SRVCC ability due to UE and IMS network can be avoided as far as possible not support UE present call state to cause SRVCC handoff failure, objective network circuit domain waste of radio resources, the problem of UE call drop/call loss.
For the ease of the understanding of those skilled in the art, the present invention is described by the specific implementation process of following examples to technical scheme provided by the invention.
