When for solution, LTE terminal receives call request under the scene that 4G network is not yet ready in the prior art, hold
The defect of easy call failure or calling delay, present embodiments provides a kind of originating method, is illustrated in figure 3 this reality
Apply example offer originating method basic flow chart, the originating method specifically includes the following steps:
S301, when terminal receives call request, the network state that is presently in of detection terminal.
Terminal in the present embodiment is that LTE terminal namely terminal are usually resident on an LTE network, when needing to complete voice
When business (such as receive calls or make a phone call), then take CSFB voice scheme fall back to can processing circuit domain (CS,
Circuit Switch) voice communication network on, and complete current voice service, i.e., the terminal will not reside in simultaneously
It LTE network and can handle on the network in the domain CS.After terminal booting, terminal can constantly execute network processes behavior, and be
Realization resides on target network, or resides on target network and prepare.In the present embodiment terminal receive it is external defeated
When the call request entered, the network state that terminal is presently in can be detected.
It should be noted that in practical applications, being not provided in the present embodiment under any terminal communication scenes
Process demand is initiated in calling, traditional processing mode is taken under application scenes, namely be in subject to LTE network in terminal
When receiving the request of user's incoming call in the case where for finishing, initiating to call after waiting terminal to be ready to complete can meet
User demand, then initiating process flow using the calling of the present embodiment does not bring significant superiority, then in order to save end
Process performance is held, traditional processing mode can be just used under this application scenarios, this is based on, the one of the present embodiment
In a little embodiments, before the network state that detection terminal is presently in, further includes: judging the communication scenes of present terminal is
It is no to meet preset calling initiation processing trigger condition, if so, the network state that detection terminal is presently in.
S302, judge whether network state is that LTE network is not ready to finish state.
Specifically, network state here includes that the ready state of LTE network or LTE network are not ready to finish state.
Wherein, the ready state of LTE network namely present terminal are in LTE network registration and finish and be just resident on an LTE network
State, and LTE network be not ready to finish state then be present terminal and be not implemented reside in LTE network, and be in
Stay in the state prepared on target network.
Wherein, in an embodiment of the present embodiment, LTE network is not ready to finish state to may include below
Any one in the pre-treatment situation that LTE network is ready to complete: LTE network just login state, LTE network search condition,
LTE cell switching state.
S303, if so, terminate the preparation behavior of current LTE network, and be directly switch into can processing circuit for controlling terminal
The target handover network of domain voice communication.
Specifically, being different from the prior art, when receiving call request under LTE network is not ready to finish state, still
Continue LTE network preparation, is being ready to complete (as completed LTE network registration) or is preparing failure (as do not searched
Suitable cell) after just initiate calling, in the present embodiment, terminal is in the case where LTE network is not ready to finish state once receive
To when call request, the preparation of current LTE network is terminated immediately, and directly controls terminal and takes CSFB voice
Scheme falls after rise to the network that can handle the voice communication of the domain CS.It should be understood that switching action here includes search mesh
Handover network is marked, is registered etc. to target handover network, the network of the domain CS voice communication can be handled to realize that terminal drops down onto
Frequency point.
In practical applications, the network of the domain CS voice communication can be handled as the target in 2G or 3G network namely embodiment
Handover network may include it is following any one: GSM network, WCDMA network, TD-SCDMA network, cdma network.
Optionally, being directly switch in controlling terminal can be after the target handover network of processing circuit domain voice communication, also
Include: controlling terminal to target handover network progress location registration, updates LAU to complete the band of position.
Specifically, in practical applications, in the mapping for being TAC to LAC, LAC is a virtual LAC, from
Numerically can be equal with practical LAC, it can not also wait, if used virtual LAC and practical LAC are numerically identical, and
Overlay area is errorless, then CSFB can choose after falling after rise is not band of position update (LAU, Location Area
Update), so that time delay can be reduced on to a certain extent, still, if terminal switchback 4G after voice communication
Network is abnormal, but network still will be considered that terminal resides on 4G network, at this time have paging to come, network will be in 4G
Network pages terminal, and actually terminal does not currently return to 4G network successfully, to will lead to paging failure.Base
In this, when falling call after rise and starting, controlling terminal carries out a LAU in the present embodiment, so that network is aware of the current institute of terminal
Locate network and the band of position, even if hereafter to return to 4G network after on-hook abnormal for terminal, and remain in 2G or 3G network,
Network can still page terminal.
Optionally, terminal currently can the changeable network of processing circuit domain voice communication have multiple when, controlling terminal is straight
Connect switch to can processing circuit domain voice communication target handover network include: obtain multiple changeable networks switching it is preferential
Grade；According to the sequence of switching priority, the highest changeable network of switching priority is determined as target handover network；Control is eventually
End is directly switch into target handover network.
Specifically, in practical applications, the changeable network that terminal can be supported can have multiple simultaneously, such as terminal returns
2G is fallen on, the caller that 3G goes to complete in the present embodiment can also be fallen back to and initiated, in the present embodiment, in order to enable terminal is returned
The network dropped down onto can guarantee the communication performance of terminal, according to the priority of multiple optional changeable networks, to select to switch
The high changeable network of priority avoids the communication performance caused by blindly switching bad as target handover network, such as cuts
It changes failure or communication quality is poor.
Optionally, the switching priority for obtaining multiple changeable networks includes: to obtain terminal to be presently in the multiple of position
The network quality of changeable network；According to network quality and the mapping relations of preset network quality and switching priority, divide
The switching priority of multiple changeable networks is not determined.
Specifically, the switching priority of multiple changeable networks can be end in some embodiments of the present embodiment
It is preset in end, such as rule of thumb data or experimental data are prepared for operator, are also possible to terminal user according to reality
Border use habit is carried out self-setting and is stored to terminal.It should be noted that in order to more suit the current reality of user
Application scenarios propose the network quality that each changeable network of position is presently according to terminal in the present embodiment, to determine
The peace of 3G equipment or 3G macro base station is not installed in the switching priority of changeable network, such as the position that is presently in of terminal
Holding position apart from current location farther out, it is poor so as to cause the 3G network covering of current location, and herein due to 2G macro base station
It is closer and 2G network signal is maintained at preferable level, in this case, then specifies the switching priority of 3G network
For lower priority, and the switching priority of 2G network is then higher, then switched to when carrying out network switching 2G network come into
Row calling is initiated, and avoids switching to caller caused by 3G network to connect time delay longer, is called access failure.
S304, under target handover network to base station initiate call.
Specifically, terminal completes current call business on the network for handling the domain CS switched in the present embodiment
Initiation, i.e., initiate corresponding call request to base station under the frequency point locating for target handover network.
Optionally, after initiating calling to base station under target handover network, further includes: established in initiation calling logical
After words process terminates, continue that terminal is kept to reside in target handover network.
Specifically, can use traditional approach in some embodiments of the present embodiment, terminal is conversed in this caller
It, can be by the automatic switchback 4G network of network, to guarantee terminal on packet-switched domain (PS, Packet Switch) after end
Excellent properties, it should be noted that the scheme of terminal switchback 4G network can using following several, first, terminal independently returns,
Second, bridge joint returns, such as it is first back to 3G network from 2G network, then 4G network is back to from 3G network again, third, across grade
It returns, such as is directed across 3G network from 2G network and is back to 4G network, can specifically be carried out according to actual use demand
Selection.But in practical applications, terminal is in LTE network and is not ready to the state finished before network switching occurs, namely
The LTE network being resident needed for terminal before this is possible to abnormal, if conventionally carrying out switchback may result in user's
Basic communication demand is all unable to get guarantee, is based on this, proposes in other embodiments of the present embodiment in this caller
After end of conversation, terminal is kept to continue to reside on the network for handling the domain CS switched to, at least enable to
The basic communication demand of user is protected.
In practical applications, in order to realize this of basic communication demand and ps domain performance, terminal can be resided in
The behavior of target handover network is limited, and in some embodiments, be can control terminal what is switched to and is handled CS
It is only resident preset duration on the network in domain, or stops the resident behavior when terminal location changes.
Optionally, before continuing that terminal is kept to reside in target handover network, further includes: judge that LTE network is not ready to
Finish the type of state, if meet preset target handover network and be resident condition；If so, continuing that terminal is kept to reside in mesh
Mark handover network.
It should also be noted that in practical applications, also being protected under not any scene in this caller end of conversation
