The function that calling subscriber can directly leave a message before user's off-hook.
Simple introduction is done to the IMS network ambient conditions that this method is based on first:
IMS is by third generation partner program (3rd Generation Partnership Project, abbreviation
" 3GPP ") a kind of IP-based network architecture for proposing, it constructs an open and flexible service environment, supports multimedia
Using relatively rich media business can be provided for user.The realization of VoLTE must rely on the deployment of IMS network, in IMS
In business system, control layer and operation layer are separation, and control layer does not provide specific business, only provide necessary touching to operation layer
The functions such as hair, routing, charging.Business triggering and control function are call session control function (Call Session in control layer
Control Function, referred to as " CSCF ") complete, CSCF points are agency (Proxy Call Session Control
Function, referred to as " P-CSCF "), inquiry (Interrogating Call Session Control Function, referred to as
" I-CSCF ") and service (Serving Call Session Control Function, referred to as " S-CSCF ") three types,
That wherein take the main responsibility is S-CSCF, and I-CSCF type is optional.Operation layer is by a series of application servers
(Application Server, referred to as " AS ") composition, can provide specific business service.Control layer S-CSCF is according to the label of user
About information control business triggering, calls the business on AS, realizes business function.End-to-end equipment in session is known as user equipment
UE (User Equipment), such as calling terminal UE, called terminal UE;It is responsible for the interaction with user.These functional entitys make
With session initiation protocol (Session Initiation Protocol, referred to as " SIP ") protocol, user equipment passes through
SIP Signalling exchange sets up the connection of the media for transmitting media data.In order to realize effective control media data, IMS net
Network connects user and network by media forward gateway, and the media data that user sends is forwarded by media forward gateway,
User wants received media data to be transmitted to user also by media forward gateway.In the business for needing to play multimedia messages
In, it may be desirable to the participation of Multimedia Resource Function (Media Resource Function, referred to as " MRF ").MRF is also referred to as matchmaker
Body server is divided into control section (MRF Control, referred to as " MRFC ") and media handling part (MRF Process, abbreviation
" MRFP "), control section is responsible for the SIP signaling translation by AS and is construed to the instruction to MRFP, and handles part and be responsible for matchmaker
Body stream sends and receives.The edge device of IMS network and conventional link exchange network is known as Media Gateway (Media
Gateway, referred to as " MG "), similar to MRF, MG points are Media Gateway Control Function (MG Control Function, abbreviation
" MGCF ") and Media Gateway (Media GateWay is referred to as " MGW ") two parts, the former is that control section the latter is media handling
Part.
The final purpose of session is media connection to be realized, it is therefore desirable to negotiate media resource information in a session.IMS system
The agreement for negotiating media resource information in system is Session Description Protocol (Session Description Protocol, abbreviation
" SDP "), protocol interaction mode be request response mode, i.e. a SDP Request must have SDP to respond.SDP Request and
The content of response is all media resource information, and media resource information includes media owner information (including address information), media
Link address, medium type and media port relevant to medium type and codec information etc..In the content that SDP is responded
Media quantity, type and sequence must in SDP Request media quantity, type and sequence it is identical.
And media connection includes two kinds, one is normal media connections, and one is the connections of early media.Normal media connection
Be after user's response SIP call request could transmission media data media connection;Early media connection is that user not yet replys SIP
Before call request can transmission media data media connection.The content of the SDP Request and response of negotiating normal media connection is just
The content of referred to as normal media SDP, the SDP Request and response of negotiating early media connection are known as early media SDP.
The technical goal to be realized of the application seeks to play to calling party by being called simultaneously in call establishment
The multimedia messages that side has customized in advance, and the multimedia messages for stopping not yet stopping after callee's response play.It is all
The media data occurred before user's response is referred to as early media.If master can be established at early media period (before i.e. called non-off-hook)
It cries to unidirectional message is called, the called message that can listen to decides whether to pick up phone again.
The present embodiment specifically comprises the following steps:
Step 101, IMS network element receive the call request of calling terminal.
Specifically, calling terminal calls called terminal, call request invite message is by calling terminal A through IMS network element road
By carrying the number of caller in call request to called terminal B.
Step 102, IMS network element call called terminal, so that called terminal root according to the called identification in the call request
According to the calling identification in call request, confirm whether calling terminal is speech verification object.
Called terminal B checks the mark of calling terminal A, and such as telephone number verifies whether " voice of having contracted to the number of A
Pre- message " business, to confirm whether calling terminal A is its speech verification object.Specifically, user can be directed in address list
Different validation problems is arranged in the incoming call of separate sources, and comes these in " voice the is left a message in advance " business contracted with operator
Electric validation problem uploads in the correspondence network element of IMS network, in media server.Need to verify caller specifically answers
With scene can there are many, for example, when in incoming number and called subscriber's address list number mismatch when;Although caller
Mark is in address list, but user is not intended to directly answer at this time, and thinks to decide whether the field answered again after confirmation incoming call is intended to
Scape;Incoming call can also be familiar with, the period, multiple dimensions such as group manage the verifying to incoming call according to Stranger Calls.
If step 103, calling terminal are speech verification object, IMS network element identifies according to called terminal and obtains called terminal
The speech verification resource being pre-stored at IMS network element.
If calling terminal A is speech verification object, called terminal B can return to Temporary Response to the AS of IMS network element, this disappears
It may include the identification information of " voice is left a message in advance " business and the number of the validation problem played in advance in breath, so that IMS network element root
Corresponding speech verification resource is obtained according to the number of validation problem.
Step 104, IMS network element send speech verification resource to calling terminal.
Specifically, after IMS network element receives the Temporary Response that called terminal B is returned, according to the mark of " voice is left a message in advance " business
Knowledge learns that calling terminal A is speech verification object, then the speech verification that validation problem number is X is extracted from the MRF of IMS network element
Resource plays to calling terminal A in a manner of early media.
Step 105, IMS network element receive the first identity code that calling terminal is fed back according to speech verification resource.
Specifically, determining that respond voice leaves a message in advance after calling terminal A listens to the speech verification resource that called terminal B is prestored
The problem of, then the first identity code can be fed back, answers validation problem to indicate that calling terminal A is ready for tone information.First
The feedback of identity code can specifically send INFO notification message by calling terminal A, include in message: dual-tone multifrequency code (dual-
Tone multifrequency, referred to as " DTMF "), such as: calling terminal A selection key " * " receives speech verification problem, then
Corresponding " * " key is corresponding to generate DTMF code, and include in Session Initiation Protocol INFO (or Notify, update message, below with
It is illustrated for INFO) in message, it is sent to the AS of IMS network element, so that media resource is updated, to realize calling terminal
A unidirectionally opens the function that sound-recording function records and can listen to recording in real time to called terminal B message, called terminal B.For example, early
" validation problem " of media, i.e. speech verification resource can be set to " may I ask you is whom, look for me what, start to record by *,
Press the # key end ", (* or # is an example herein, is also possible to other number keys).
According to the first identity code, the one-way voice established between called terminal and calling terminal is stayed for step 106, IMS network element
Say channel, so that calling terminal only sends voice signaling, called terminal only receives the voice signaling of calling terminal transmission.
Specifically, current intelligent terminal is powerful, sound-recording function is supported, between called terminal B and calling terminal A
One-way voice channel of leaving a message for making calling terminal A send voice signaling record one section of tone information to called;It is called
Terminal B only receives the voice signaling of calling terminal A transmission, i.e., it is called can only receive (can also by the tone information received into
Row storage local or cloud) and obtain in real time or later and listen to the message of caller.Wherein, the reception of tone information can be by IMS
The server side of network is realized, can also be realized by terminal side, if being realized by terminal side, be can use existing in intelligent terminal
Sound-recording function module is completed, thus mitigate the AS server burden of IMS network, it is also small to the revamping workload of network.
Step 107, IMS network element receive the second identity code, according to the second identity code, establish called terminal and calling terminal it
Between two-way call channel so that calling terminal sends or receives voice signaling, called terminal sends or receives voice signaling.
Specifically, that is, calling terminal A is in called terminal B and stays during the occupancy in one-way voice message channel
It makes peace during answering message, either party can interrupt the process at any time, for example, called terminal B is according to preset record
Likeness of the deceased amount or record length stop message;Or called terminal B by off-hook or is answered and is buttoned to end message;Or calling terminal
A interrupt etc. by terminating the key of message;Then IMS network element receives the second mark corresponding to above-mentioned various interrupt modes
Will code carries out media information again and updates, configuration caller and called two-way media channel.It selects to connect if being called after listening to recording
Listen, then can be carried out by well-established two-way media channel it is normal connect session, if it is called listen to recording after select to hang up,
Then terminate session by normal flow.
In conclusion the voice leaving method provided in this embodiment based on IMS network, by receiving exhaling for calling terminal
Request is cried, and forwarded call request allows called terminal according to calling identification, confirm whether it is that voice is tested to called terminal
Demonstrate,prove object;If so, obtaining called terminal is pre-stored in the speech verification resource at IMS network element, to carry out language to the calling terminal
Sound verifying;If calling terminal receives speech verification, the first identity code is fed back, then IMS network element establishes quilt according to first identity code
Cry the one-way voice message channel between terminal and calling terminal;Called terminal is set to receive the voice recording of calling terminal, i.e. language
Message enables;IMS network element also receives the second identity code, according to second identity code, establishes between called terminal and calling terminal
Two-way call channel, so that calling terminal and called terminal can mutually transmit and receive voice signaling.To utilize telephone connection
(jingle bell) process provides real-time voice message to the incoming call of calling subscriber and plays, allows called subscriber by listening to message
The one's purpose in coming of caller incoming call is known in advance, and can answer the phone of calling subscriber at any time during or after message, is realized double
To call, this method facilitates user and predicts incoming call intention before not receiving calls, improves incoming call sound efficiency, promotes user's body
Test sense.
Fig. 2 is a kind of flow chart of the voice leaving method based on IMS network shown according to another exemplary embodiment.
Fig. 3 is a kind of signaling interaction diagram of voice leaving method based on IMS network shown in an exemplary embodiment.As shown in figure 3,
Step S301, assume that calling terminal A is the domain CS terminal, called terminal B is IMS domain terminal;Calling terminal A initiation is exhaled
It cries, generates invite invitation message, carry and early media (P-early-media:supported) is supported to identify, it is whole to carry caller
The SDP of A is held to describe (the normal media resource information including calling terminal A).
Step S302, invite message by routing by caller A the domain CS transmission of network to called terminal B IMS network,
It is ultimately delivered to called terminal B.For brevity, IMS network has been simply included to the IMS network element of CSCF, AS, MRF.
Step S303, after called terminal B receives invite message, incoming number (Tel format and/or SIP lattice are extracted
Formula) and called terminal B in address book information compare:
If A, incoming number is in the address list of called subscriber, and this number is not that " voice is left a message in advance by user setting
Number " is then called according to normal flow;
If B, incoming number not in the address list of called subscriber or incoming number in the address list of called subscriber but
User is provided with " voice is left a message in advance " business to the number, then carries out step S304.
Step S304, called terminal B generates 180 response messages (180ringing), and carries early media flag position
(pre-media), the number X of " voice is left a message in advance " service identification (pre-media mark) and validation problem can also be carried, is passed through
By CSCF/AS/MRF-B, because AS has learned that calling terminal A supports early media, and have again in 180 response messages received at this time
Pre-media field, then activate " voice is left a message in advance " function, and AS obtains the speech verification resource that number is X to MRF.
Step S305,180ringing message is transmitted to caller A, the SDP media letter of addition media server MRF by AS
Breath, and the header field for adding early-media information is the mark (P-pre-media:sendonly) for only sending voice signaling, shows this
When SDP response be early media SDP, and media resource is the media money for making calling terminal A be configured to only to send voice signaling
Source.
Step S306, calling terminal A returns to confirmation message (PRACK).
Step S307, IMS network element transmits the confirmation message (PRACK) to called terminal B.
Step S308, called terminal B with response message 200OK (PRACK) message complete to 180ringing message can
By property response.
Step S309, after IMS network element transmits the response message 200OK (PRACK) message, the early matchmaker of calling terminal A and MRF
Body is negotiated to complete, and the early media audio file for the speech verification resource that number is X at this time can smoothly play to calling terminal A.
Step S310, after calling terminal A hears the early media audio file of speech verification resource, can there are two types of selection:
A, any operation is not taken, waits called terminal B off-hook or on-hook, follow-up process can be according to existing always
Standard agreement process continue.
B, " * " number key is pressed in calling terminal A selection, continues to execute step S311, prepares to start the verifying according to called terminal B
Problem makes speech answering.
Step S311 is on the basis of the above embodiments, how to establish the specific of one-way voice message channel to calling and called
Illustrate, further, as shown in Fig. 2, step 106, according to the first identity code, establish the list between called terminal and calling terminal
To tone information channel, can specifically include:
Step 1061, IMS network element are requested according to the foundation that first identifier code sends one-way voice message channel, so that called
Terminal updates called SDP media information according to request is established, and generates the first called SDP media information, and send the first called SDP
Media information is to IMS network element.
Wherein, include in the first called SDP media information: only receiving the mark of voice signaling.This only receives voice signaling
Mark can be by the header field in the first called SDP media information to set recvonly to realize.
The first called SDP media information is sent calling terminal by step 1062, IMS network element, so that calling terminal updates
Caller SDP media information generates the first caller SDP media information, sends the first caller SDP media information to IMS network element.
Wherein, include in the first caller SDP media information: only sending the mark of voice signaling.This only sends voice signaling
Mark can be by the header field in the first caller SDP media information to set sendonly to realize.
The first caller SDP media information is sent called terminal by step 1063, IMS network element, so that called terminal and master
It is the one-way voice message Path Setup between terminal.
IMS network element will be called updated media resource and be transmitted to caller, and the updated media resource of caller is forwarded
To being called, the media resource matching of calling and called is completed.
In the detailed Signalling exchange process of 1061~step 1063 of above-mentioned steps signaling interaction diagram shown in Figure 3
Step S311 to step S317.
Step S311, calling terminal A selection is when pressing " * " key, generate in a Session Initiation Protocol notification message INFO (or
Notify, update message, are subject to INFO herein), to collect the digits in DTMF event band or with collecting the digits outside in a manner of transmit
To AS, early media flag position pre-media, " voice is left a message in advance " flag bit pre-media are carried in INFO message.
Step S312, AS learns that calling terminal A needs to carry out " language by the DTMF code of correspondence " * " after receiving INFO message
Sound is left a message in advance " business, it is therefore an objective to reach calling terminal A one-way transmission RTP voice flow and give called terminal B, then stops early media
It plays, at this time because of the also non-off-hook of called terminal B, is unable to get the SDP media information of called B, in this AS in order to construct
The 200OK message of called terminal B out can send out one and re-invite message re-invite, the inside include empty SDP media information,
Early media flag position pre-media gives called terminal B.
Step S313, after called terminal B receives the re-invite with " pre-media " mark, a 200OK is constructed
Response message includes the media information SDP B of called terminal B in message, only receives the mark of voice signaling, early media flag position
Pre-media, wherein the mark of voice signaling is only received by setting a=recvonly realization for the header field of message, thus
Allow the reception audio medium stream that called terminal B is unidirectional.
Step S314, then AS construction updates media information between update calling terminal A and called terminal B, to realize
The one direction voice medium of calling terminal A and called terminal B transmits, and has changed the matchmaker of SDP B in update message update at this time
Body direction is a=recvonly, further includes: stops the mark (P-pre-media:inactive) of early media play.
Step S315, calling terminal A replys response message 200OK, carries SDP A, and change media direction is only to send language
It is unidirectional to called terminal B transmission audio medium stream to indicate that calling terminal A is ready by the mark a=sendonly that message enables, but by
Make terminal B that can only receive and cannot send.Further include: stop the mark (P-pre-media:inactive) of early media play;
Early media flag position pre-media etc..
Step S316, IMS network element sends the media information of calling terminal A to called terminal B, so that called terminal B is opened
Sound-recording function is opened, there are local terminals for the real-time voice RTP packet that calling terminal A is transmitted;Simultaneously because update message before is
Through stopped the broadcasting of early media, thus do not influence voice RTP packet at this time it is unidirectional be transferred to called terminal B.
Step S317, when calling terminal A receives response message 200OK (invite) constructed by AS, according to negotiation
Good media formats establish the calling terminal A media channel unidirectional to called terminal B, send " voice is left a message in advance ", as " I am
XXX looks for you to have a talk the thing of XX ".At this time although B does not have off-hook, but B has begun and receives the real-time voice matchmaker that A is sent
Body stream, and the message of caller at this time is recorded in terminal local by the calling to sound-recording function.
So far, stop playing early media, calling terminal A initiates unidirectional real-time voice media, answers validation problem.
Fig. 4 is a kind of flow chart of the voice leaving method based on IMS network shown according to another exemplary embodiment.
As shown in figure 4, on the basis of the above embodiments,
Further, step 107, the second identity code of reception establish called terminal and calling terminal according to the second identity code
Between two-way call channel, can specifically include:
Step 1071 receives the second identity code, according to the second identity code, sends to calling terminal and is properly received the second mark
The feedback information of code.
Specifically, the second identity code may include: the closing identity code that called terminal closes one-way voice message channel;Or
Person includes: the timeout flag code for reaching one-way voice message channel duration threshold.For example, the second identity code is calling terminal
A terminate recording after by " # " number key or long recording time reach preset threshold timeout flag code (8 seconds) etc..
Step 1072 receives the second caller SDP media information that calling terminal is sent.
Wherein, to be calling terminal carry out caller SDP media information more according to feedback information to the second caller SDP media information
It is generated after new.Include in second caller SDP media information: sending and receiving the mark of voice signaling.This sends and receives language
The mark that message enables can be to set sendrecv for the header field in the second caller SDP media information to realize.
The second caller SDP media information is sent called terminal by step 1073, IMS network element, so that called terminal updates
Called SDP media information, generates the second called SDP media information, sends the second called SDP media information to IMS network element.
Wherein, include in the second called SDP media information: sending and receiving the mark of voice signaling.This sends and receives
The mark of voice signaling can be to set sendrecv for the header field in the second called SDP media information to realize.
The second called SDP media information is sent calling terminal by step 1074, IMS network element, so that called terminal and master
It is the two-way call Path Setup between terminal.
The detailed signaling process in the above-mentioned two-way call channel established between called terminal and calling terminal can continue to join
Examine signaling interaction diagram shown in Fig. 3.
Step S318, calling terminal A is pressed the # key after terminating recording or (record length can be set in long recording time arrival
It must not exceed 8s etc.).
Step S319, calling terminal A generates a update update message, by the media row a=of SDP A in message content
Sendonly is changed to a=sendrecv, that is, sends and receives the mark of voice signaling, indicates to release one-way transmission media at this time
Form is changed to not only send but also can receive the form of Media Stream, at this time the matchmaker between calling terminal A and called terminal B
Body, which is negotiated to update, arrives intercommunication mode, starts the media interaction of both sides.
Step S320, IMS network element is forwarded update message, after called terminal B receives update, terminates recording.Quilt
Make terminal B with real-time recording and tone information can be listened to during terminating to record opening recording.
Step S321, called terminal B replys 200 OK of response message, and media row is changed to a=sendrecv, table in message
Show that called terminal B is also that can send and receive Media Stream.So that double-directional speech Path Setup.
Step S322, IMS network element is forwarded 200 OK of response message, and calling and called terminal is made to carry out media information
Match, completes double-directional speech Path Setup.
If called terminal B selects not answer the call after listening to recording at this time, call is terminated by normal flow.If at this time by
Terminal B selection off-hook after listening to recording is made to receive calls, called terminal B can send 200OK (for the invite for initiating calling
Message), calling terminal A and called terminal B can be talked with end to end at this time.Notice that 200 OK message at this time no longer contain
There is SDP message, because media update before has finished on.
In addition, for optimization user experience, if the number of calling terminal A is not present in the address list of called terminal B
In, then after called terminal B and calling terminal A end of conversation, can be popped up on the interface UI of intelligent terminal prompting frame " whether
Calling terminal A is added in address list ", avoid calling terminal A next time from calling the verifying for also needing to carry out for unknown number
Situation.
In addition, the optimization of following aspect can also be carried out on the interface UI: after called terminal B ring, waiting for a period of time, such as
Calling terminal A has selected " voice is left a message in advance " function to fruit at this time, and called terminal B is being given to leave a message, and the ring of called terminal B updates
For mute or vibration, while " voice is left a message in advance " for receiving caller is shown on the interface UI, promote user experience.If by
Cry and hung up after listening to message, illustrate that the message is inessential or the number is harassing and wrecking number, should be prompted on the interface UI whether by this
Number is added blacklist or whether deletes recording, in order to avoid occupy local resource.
The above process realizes the operation flow of the early media one-way transmission Media Stream based on IMS network, makes called subscriber
Verifying, which requires, to be proposed to the incoming call verified, after caller receives the validation problem of speech verification resource and receiving, with
DTMF event is sent to the application server of IMS network element, and application server renegotiates caller and called media resource, make caller with
The mode of one-way voice Media Stream answers verifying to i.e. tone information and is sent to called, the called sound-recording function note for calling terminal
Record, makes to be called the speech answering that can hear that caller is carried out according to validation problem before non-off-hook, it is then called can be according to staying
Speech content is decided whether to answer or be hung up.Wherein, the change in terms of caller is without doing software and hardware can be the storage now netted
Terminal (2G/3G/ fixed network user), being called can be in the IMS terminal of IMS domain registration.
Further, in step 107, establish the two-way call channel between called terminal and calling terminal after, may be used also
To include: to receive third identity code, if third identity code is the identity code that refusal answers calling, it is logical to discharge two-way call
Road;If third identity code is the identity code for answering calling, two-way call channel is connected, so that calling terminal and called end
End carries out voice communication.
Need to coordinate the media resource of double-talk end to end before calling and called converse, but whether using should
The media resource of two-way call, it is also necessary to be determined according to the triggering of the third identity code, if third identity code is to answer caller
The identity code of calling then connects two-way call channel, so that calling terminal and called terminal carry out voice communication.

Management.For example, according to the period, relationship type, the customized different speech verification resource such as group.Such as strange
Number, speech verification resource can for " you who, look for me what, by * message, # terminates to leave a message and wait a moment ";For inoperative
Period, when being not desired to be disturbed, the group, company in address list is set as " I is on furlough, busy to leave a message,
Start to leave a message by *, terminated to leave a message and be waited a moment by # ";The moment that receives calls is inconvenient to for certain, and " I is set as to all incoming calls
It is busy to leave a message on driving/meeting/road, start to leave a message by *, terminated to leave a message and be waited a moment by # "." waiting a moment " is in order to called
For user there are listening to take recording, thinking is the discovery that the time of important phone.
Speech verification resource can have multiple, targeted objects, period different.By standard Ut, returning
Belong to assigned user server (Home Subscriber Server, referred to as " HSS ") to be authenticated, business configuration proxy gateway will
Service request is sent to application server AS, and AS issuing service permission gives UE (being herein called terminal), and user recording is uploaded
" speech verification resource " classified storage is at MRF (on media server), and record traffic triggering is regular, as table 1, speech verification provide
Shown in the table of source:
Correspond to the different periods in the table 1, the problem of different incoming call type, settable different phonetic is left a message in advance,
It respectively numbers for corresponding one, the AS in IMS network element is when being sent to calling terminal for speech verification resource, by the language of different numbers
The problem of leaving a message is stored on MRF sound in advance, and when incoming number is routed on called terminal, called terminal judges incoming call type, then
