Technical field
The present invention relates to the communications field more particularly to a kind of reverse single-standby service continuity carrying switching methods and device.
Background technology
IP multimedia subsystem (IP Multimedia Core Network Subsystem, IMS) is closed by the third generation
Make a kind of IP-based network rack of Partnership Program (3rd Generation Partnership Project, 3GPP) proposition
Structure constructs an open and flexible service environment, supports multimedia application, can provide relatively rich media sector to the user
Business.
In IMS business systems, control layer and operation layer are separation, and control layer does not provide specific business, only to business
Layer provides the functions such as necessary triggering, routing, charging.
Business triggering and control function are call session control function (Call Session Control in control layer
Function, CSCF) complete.Call session control function is divided into：Proxy Call Session Control Function (Proxy-CSCF, P-
CSCF), query call conversation control function (Interrogating-CSCF, I-CSCF) and service call conversation control function
(Serving-CSCF, abbreviation S-CSCF) three types, wherein that take the main responsibility is S-CSCF, I-CSCF is optional.
Operation layer is made of a series of application servers (Application Server, AS), and specific business can be provided
Service, AS can be independent entity, can also exist in S-CSCF.
Control layer (S-CSCF) controls business triggering according to the signing information of user, calls the business on AS, realizes business
Function.
End-to-end equipment in session is known as user equipment (User Equipment, UE), is responsible for the interaction with user,
Some UE have the mode of a variety of access networks, include accessing net by domain packet switch (Packet Switch, PS) of 3GPP
Network accesses network, it might even be possible to access by the domain circuit switching (Circuit Switch, CS) by the ps domain of other non-3 gpp
Network etc..
If CS network configurations enhancing mobile switching centre (enhanced Mobile Switch Center, eMSC),
Initial session protocol (Session Initial Protocol, SIP) interface is provided by eMSC to interact with IMS network, then IMS
The interaction of network and CS networks can be realized by eMSC.
For the UE with plurality of access modes, if the UE moment can only use a kind of access way,
It is carrying out talk business under the access way of 2/3G networks, because talk business is provided in 2/3G networks by the domains CS, works as UE
It is moved to elsewhere and needs to change the access way that it is used to be long term evolution (Long Term Evolution, LTE) net
When network or high-speed packet access (high speed packet access, HSPA) network insertion, UE and network can provide certain
The talk business that mode makes UE be carrying out is not disrupted, because talk business is provided in these networks by ps domain, such energy
Power is switched to the continuity of ps domain, abbreviation reverse single-standby service continuity we term it terminal speech business is singly waited for from the domains CS
(reverse Single Radio Voice Call Continuity, rSRVCC), it is corresponding, if it is UE from
LTE network or HSPA Network Mobilities are then referred to as singly to wait for terminal traffic continuity to 2/3G networks, and referred to as single standby service is continuous
Property (SRVCC).
Fig. 1 is that existing reverse single-standby service continuity carries switching flow figure, describes and is established between UE-1 and UE-2
Call, UE-1 are to establish call by the domains CS of 2/3G networks, therefore that connect UE-1 in media path of conversing is one section of CS

Journey comprising following steps：
Step 101：UE-1 establishes session, while UE- by the domains CS and the original domains network C S controlled entity, i.e. MSC with UE-2
1 also has movable PS business, therefore there are the connections of movable PS service bearers；
Step 102：UE-1 sends measurement report to for its former network serviced, to report cell signal strength to measure letter
Breath；
Step 103：For the base station system of the former network of UE-1 services, such as BSS or RNC, according to each small in measurement report
Area's signal strength information judges that neighbouring PS target networks are more suitable for servicing as UE-1, then determines to execute handover operation, former net
The base station system of network sends CS switching requests to MSC, for example sends Handover required (switching request) message, carries
Target identification information, such as Target cell (Cell) mark or target enhanced Node B (eNB) marks etc. connect for identifying target
Enter the information of position；
Step 104：MSC receives switching request, and dns resolution is carried out using information some or all of in target identification information
The address information of target network controlled entity is obtained, and to target network controlled entity, such as MME or SGSN, initiates CS to PS
Switching request, for example send CS to PS Forward Relocation Request；
Step 105：Simultaneously with step 103, because UE-1 also has movable PS business, thus the base station system of former network also to
Former network data domain controlled entity, such as SGSN send PS switching requests, for example send Relocation Request (switchings
Request) message, carry target identification information；
Step 106：Former network data domain controlled entity carries out DNS using information some or all of in target identification information
Parsing obtains the address information of target network controlled entity, and sends switching request to target network controlled entity, for example sends
Forward Relocation Request message；
Step 107：Target network controlled entity merges the information in two switching requests of step 104 and step 106, and
To target network base station system, such as eNB or RNC, switching request is sent, for example send Handover Request message, taken
The carrying information to be reserved of band；
Step 108：Target network base station system reserves resource, then sends switching response message, for example send
Handover Response message；
Step 109：Target network controlled entity sends CS to PS handoff responses to MSC, for example sends CS to PS
Forward Relocation Response message.
Step 110：MSC sends switching command, for example send to former network base station system, such as RNC or BSS
Handover Command message；
Step 111：Simultaneously with step 109, target network controlled entity sends to former network data domain controlled entity and switches
Response, for example send Forward Relocation Response message；
Step 112：Former network data domain controlled entity sends switching command to former network base station system, for example sends
Handover Command message；
Step 113：The information in switching command in former network base station system merging step 110 and step 112, and to
UE-1 sends switching command, for example sends Handover From UTRAN message；
Step 114, UE-1 receive switching command, are modulated to target network ps domain access target network；
After step 115, UE-1 access target networks, handoff notification message is sent to target network base station system, for example send out
Send Handover Notify message；
Step 116, target network base station system send handoff notification message to target network control network element；
The bearer connection of step 117, target network control network element update core net, such as to target network gateway, than
Such as SGW, Modify Bearer Request message is sent, so that target network base station system is established with target network gateway
Bearer connection；
Step 118：Target network gateway sends the message of more new bearer to data network gateway, for example sends Modify
Bearer Request message, so as to establish bearer connection between target network gateway and data network gateway；
So far, IMS media connection 1 is set up between UE-1 and UE-2, and UE-1 passes through target network with data network gateway
Base station system and target network gateway set up bearer connection, and UE-1 and UE-2 is enable to continue to converse, and the PS business of UE-1 can
