Video is switched to the domain packet switch (PS, Packet Switched) by Switched) domain, and switching control request message carries v '
SRVCC mark；
E-UTRAN switches over control to UE according to the measurement result of UE.LTE network can directly ask switching control
It asks message to be sent to UMTS, or control is switched over by MME, the present embodiment is lifted with switching over control by MME
Example explanation, does not constitute restriction of the invention.
Step 302, MME carry out carrying separation, i.e. holding the carrying of QCI=1, the carrying of QCI=2 and QCI=5
It carries and is separated from other PS carrying；
Wherein, since Android system does not support more APN, then in step 302, MME can also initiate PDN
Connectivity deletes process, deletes the default bearer of QCI=9；If not Android mobile phone can not then delete lacking for QCI=9
Save carrying.
After carrying separation, it can initiate the redirection towards MSC Server and SGSN respectively, wherein MME is to MSC
Server initiates QCI=1 carrying and is switched to CS, and the carrying for initiating QCI=2 and QCI=5 to SGSN is redirected to PS.
Step 303, MME initiate the request that QCI=1 is switched to CS to MSC Server, which carries v ' SRVCC；
Wherein, v ' SRVCC notifies IP multimedia subsystem (IMS, IP Multimedia by MSC Server for MME
Subsystem video port) is not closed.This is because the side IMS can be cut when IMS system detection is switched to CS TS11 to voice
Disconnected video bearer increases v ' SRVCC mark newly to keep video streaming logical, notifies IMS to be not related to by MSC Server for MME
Close video port.
It should be understood that the switching request message also carry IMSI, Target ID, STN-SR, C-MSISDN,

Know.
Wherein, MSC Server is received be redirected to the request of CS after, can returning response this be redirected to the request of CS
Response message.
Step 304, MME initiate the request that QCI=2 is redirected to PS to SGSN；
MME in LTE sends the request for being redirected to PS to the SGSN in UMTS, which carries generic Source
To Target Transparent Container, MM Context and PDN Connections IE, wherein PDN
The carrying ID of carrying and QCI=2 in Connections IE comprising QCI=5.
Wherein, SGSN is received be redirected to the request of PS after, can returning response this be redirected to the response of the request of PS
Message.
It should be noted that step 303 is unrelated with 304 timing.
After step 305, MME receive the response message of MSC Server and SGSN, switching command message is sent to UE, is made
It obtains UE and is switched to UMTS from LTE；
Wherein, after UE completes switching, RNS sends SES and MSC Server, UE and target MSC Server is given to rebuild connection,
Voice messaging can be sent and received.
Step 306, CS switching are completed, and MME deactivates QCI=1 carrying；
Step 307, PS switching are completed, and Target SGSN initiates bearer update request, and user face is switched to from source eNodeB
Target RNC。
Step 308, PS switching are completed, and MME initiates session removal request, delete IMS APN associated session and carrying (QCI
=2 and QCI=5).
It will be described in detail below with concrete application example when the PDP secondary activating that UE does not support UMTS network to initiate, QCI=
How video traffic in 2 carryings is redirected to PDP Context of UMTS network:
In a kind of embodiment, after the completion of CS switching, within step 306, LTE deletes QCI=1 and QCI=2 carrying, depending on
Frequency Business Stream is tied to default bearer in the side LTE, may include steps of:
Within step 306, after the completion of CS switching, QCI=1 and QCI=2 carrying is deleted, and video flowing is tied to QCI=
5 default bearers, then, the QCI=5 carrying that is switched to of PS is switched to PS.Wherein, data can be planned in advance, so that view
Frequency stream can be tied to QCI=5.
That is, video flowing uses a PDP Context in UMTS network；In LTE network, video flowing is using proprietary
Carrying.
In embodiments, it deletes QCI=2 carrying to be initiated by MME, only has dependence to MME, to other network elements without dependence
Property.Therefore, after mobile phone is switched to UMTS network, if mobile phone does not support the secondary PDP activation of UMTS network initiation, preferably should
Embodiment.
In a kind of embodiment, it directly is switched to UMTS network from LTE network, the carrying by UMTS system to handover success
Bearer update is initiated, deleting load-bearing initiated to the carrying of handover failure, and by the bearing binding of handover failure a to PDP or more
Text.
Carrying to handover failure, it is specific can include: SGSN initiates deleting load-bearing request to SGW/PGW, GGSN to
PCRF reports the PCC rule install failure of RAT Type and QCI=2, and PCRF deletes the Rule information of install failure, and to GGSN
CCA response message is returned, the Rule information of install failure is tied to a PDP Context by UGW.
It is understood that illustrating that mobile phone supports secondary PDP to swash if GGSN does not receive the message of regular install failure
It is living, then continue to execute step 308 by MME.
It should be noted that when supporting secondary PDP context activation for mobile phone, video be can be switched in present embodiment
Dedicated bearing is experienced secure.When without supporting secondary PDP context activation, video can be switched to a PDP Context.This
Embodiment is adapted to the case where mobile phone supports secondary PDP context activation and do not support secondary PDP context activation.Cause
This, after mobile phone is switched to UMTS network, if mobile phone support UMTS network to initiate secondary PDP activation, the preferred embodiment party
Formula.
Therefore, if UE is in the secondary PDP activation that UMTS network supports network to initiate, QCI=2 carrying is switched to UMTS net
The secondary PDP Context of network, it is only necessary to execute step 307；
If the secondary PDP activation that UE does not support UMTS network to initiate, data need to be mapped to UMTS's in QCI=2 carrying
Default bearer (i.e. a PDP Context) needs SGSN to initiate secondary PDP Context and deletes process.I.e. in step 307,
Further include: PS switching is completed, and to the context for establishing failure, the PDP context that SGSN initiates failure deletes process notice
GGSN rule establishes failure, and video flowing is tied to PDP Context of UMTS by GGSN.
It, specifically can be by newly increasing 3 bytes in C-MSISDN to keep video streaming logical in the present embodiment
(999) v ' SRVCC is identified, implementation may refer to following table one and table two, wherein table is first is that traditional embodiment, table
