Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, technical solution in the embodiment of the present invention is explicitly described, it is clear that described embodiment is the present invention
Embodiment a part of the embodiment, instead of all the embodiments.
The call setup process of session all the way are as follows:
The process of signaling plane: VoLTE is established using SIP, modification and deletion session, caller initiate sip message to network side
INVITE, starts SIP call signalling flow since then, and calling and called are completed to negotiate.
Medium surface process: calling and called are completed after negotiating, and calling and called establish Media Stream, carry out Communication, Communication
Mode is to exchange the data packet of RTP and RTCP.
Calling release process are as follows:
The process of signaling plane: a side sends BYE (on-hook) message.
Medium surface process: no longer exchange data packets.
SIP call flow includes multiple sip messages, since INVITE message, by 100trying (response),
180ring (ringing information), 200ok (successfully indicating) and ACK (determining message) stop afterwards, wherein include mark in INVITE message
Know information, specifically: caller ID (Identification, identification), caller IP address/port numbers.
Media Stream includes multiple data packets, and it includes identification information in data packet that data packet, which belongs to IP packet, specifically: caller
IP address/port numbers, the identification information of data packet is identical in the Media Stream of session all the way.
Media Stream includes realtime transmission protocol RTP stream and RTCP Real-time Transport Control Protocol RTCP stream.
Correspondingly, data packet includes RTP packet and RTCP packet, and RTCP is the agreement being used cooperatively together with RTP, when starting one
When the medium surface of road session, two ports will be occupied simultaneously, be used respectively for RTP and RTCP.
Calling and called periodical exchange RTP packet and RTCP packet, resource size that RTP packet and RTCP packet occupy are sent
Period can not be identical, wherein RTP encapsulation voice data, that is, the call voice of calling and called, RTCP encapsulation Network status
Data, provide the information of quality of the conversation or performance quality, such as the quantity and RTP packet of the sum of RTP packet, the RTP packet of loss
Shake situations such as.
Due to not including caller ID in data packet, it is common ground that caller IP address/port numbers are used in the embodiment of the present invention
It is associated.
If INVITE message and Media Stream belong to same session all the way, caller IP address and data packet in INVITE message
In caller IP address be consistent, and the caller port numbers in the caller port numbers in INVITE message and data packet are also one
It causes.
Optionally, caller ID is unique identification when terminal unit contractual networks, and will not be changed over time, optionally, main
It is IP address and port numbers is that terminal is attached to IMS network, be the IP address and port numbers of terminal distribution by IMS network, if hair
Raw off-grid, then redistribute caller IP address and port numbers.
Port numbers are the unique identifications of the logic port for differentiated service, are one-to-one, caller IP with IP address
Address or port numbers can identify the identity of current caller.
That is, if caller IP address/port numbers in INVITE message and caller IP address/port in data packet
It number is consistent, then the caller ID in INVITE message can be backfilled in data packet, so that data packet and calling and called be closed
Connection gets up, and to this, session is assessed all the way.
It is flowed according to rtp streaming or RTCP, can all carry out speech quality evaluation.It is of course also possible to be flowed into conjunction with rtp streaming or RTCP
Row Speech Assessment.
In practical application, in the step of acquiring SIP call flow, it is possible to be lost INVITE message, then data packet
IP address be associated with less than INVITE message, so that data packet cannot backfill, therefore the data packet is abandoned, and media are equivalent to
Facial divided data packet does not carry out the assessment of speech service quality, on the whole, affects speech service quality assessment
Accuracy can avoid this problem occur using the method for the embodiment of the present invention.
Fig. 1 shows a kind of flow diagram of the method for association process provided in an embodiment of the present invention.
As shown in Figure 1, method provided in an embodiment of the present invention specifically includes the following steps:
The protocol IP interconnected between the caller network of at least one the first Media Stream in step 11, acquisition first time period
Location/port numbers, first Media Stream is the Media Stream that can not be associated with the invitation INVITE message of first time period, and is obtained
The calling identification sign ID and master of the INVITE message of at least one Session initiation protocol SIP call flow in second time period
IP address/port numbers are, the second time period is before first time period and adjacent with first time；
Before this step, the second time period described in signaling plane and the first time period, the SIP call-flow of acquisition
Journey, and the INVITE message of the SIP call flow of acquisition is cached, for the second time period and it is described first when
Between the Media Stream of section be associated.
Media Stream and SIP call flow to each period are all associated, in embodiments of the present invention, to first
Media Stream in period is illustrated for being associated with SIP call flow.
Optionally, it is associated with by the INVITE message with data packet, so that SIP call flow and media stream associations be risen
Come.
Optionally, association refer to search first time period in Media Stream caller IP address whether in first time period
The caller IP address of INVITE message is consistent, or whether searches the caller port numbers of Media Stream in first time period with first
The port numbers of INVITE message are consistent in period.
The lookup of any one of caller IP address and port numbers is consistent, and it is believed that being successfully associated, the embodiment of the present invention is with caller
It is illustrated for IP address.
If the caller IP address of the Media Stream in first time period is consistent with the caller IP address of INVITE message, it is believed that close
It is unified into function, the caller ID of the INVITE message is backfilled to each data packet of the Media Stream.
If inconsistent, it is believed that do not collect consistent INVITE message in first time period, therefore can not be by INVITE
Message and the media stream associations, obtain the first Media Stream.
Optionally, first time period and second time period can be arranged according to the actual situation, for example, first time period is (9
- 9 point of point 30 minutes] this 30 minutes, second time period be (8: 30 assign at 9 points] this 30 minutes.
Optionally, according to every one first Media Stream in first time period, respectively with SIP call flow in second time period
It is associated.
In the case that Media Stream in first time period is associated with failure with SIP call flow, when also attempting with others
Between, SIP call flow is associated in second time period.
Optionally, according to the caller IP address of every one first Media Stream, the master of the INVITE message of second time period is searched
It is IP address.
If caller, between first time period and second time period, there is no shutting down, leave ownership place and open to fly
The off-grids behavior such as row mode, caller IP address/port numbers are usually constant, it is believed that caller IP address/port numbers are identical, then
It really is same caller.
Due to that, there is no the INVITE message with media stream associations, can continue to look into second time period in first time period
Look for whether same caller initiates session.
If the caller of the INVITE message of caller IP address/port numbers and second time period of step 12, the first Media Stream
IP address/port numbers association is consistent, then the caller ID of the INVITE message of second time period is backfilled to the first Media Stream.
If second time period exists consistent INVITE is matched with the IP address of the first Media Stream of first time period disappear
Breath indicates that before first time period, another session, second time period pair were also initiated in same caller in second time period
The INVITE message for the session answered collects, and the INVITE message of the corresponding session of first time period, which acquires, loses.
Optionally, voice quality has much relations with when and where, due to temporally adjacent, even if being different two-way meeting
Words, it is believed that caller is not moved, and the voice quality of this two-way session is similar, by the master of the INVITE message of second time period
The data packet for making ID be backfilled to the first Media Stream.
Speech quality evaluation is carried out according to the corresponding SIP call flow of the INVITE message and the first Media Stream.
The corresponding SIP call flow of the INVITE message and the first media stream associations get up to be equivalent to complete all the way
Session carries out speech quality evaluation for complete session.
If the IP address matching of the INVITE message of the first Media Stream and second time period of first time period is inconsistent,
Then think that first Media Stream can not be associated with, terminates process.
In embodiments of the present invention, for the first time, (INVITE message of the first Media Stream and first time period) is associated with failure
When, also carry out it is secondary be associated with (by the INVITE message of the first Media Stream and second time period), associated success can be improved
Rate.
If secondary be successfully associated, the caller ID of INVITE message is backfilled to the first Media Stream, then to INVITE message pair
The SIP call flow answered and the first Media Stream carry out the assessment of speech service quality, reduce the feelings for abandoning the first Media Stream
Condition improves speech quality evaluation accuracy on the whole.
The method of association process provided in this embodiment, by INVITE message and media stream associations failure after, also into
Two secondary association of row, can be improved associated success rate, in the case where not changing agreement, can accurately carry out voice quality and comment
Estimate, so as to the realization speech quality evaluation of simple economy.

Suddenly specifically:
If the caller IP address of the INVITE message of caller IP address/port numbers and second time period of the first Media Stream/
Port numbers association is consistent, and caller IP address/port numbers of the INVITE message of second time period and third period
Caller IP address/port numbers of INVITE message are consistent, and the caller ID of the INVITE message of the second time period and the third
The caller ID of the INVITE message of period is consistent, then the caller ID of the INVITE message of second time period is backfilled to the first matchmaker
Body stream.
Assuming that caller IP address/port numbers by IMS network side are allocated to caller A in second time period, second has been initiated
The session of period, in first time period, equal off-grids behavior is had occurred in caller A, and the IP address of caller A is by IMS network side point
Dispensing caller B, the session of caller B in first time period there is no the INVITE message with media stream associations, at this time second
It is not the session that same caller is initiated in period and in first time period.
That is, second time period is identical with the IP address of first time period if caller IP address is reallocated, but
It is not same caller, the INVITE message of second time period should not should not also be incited somebody to action with the first media stream associations of first time period
The caller ID of the INVITE message of second time period is backfilled to the first Media Stream.
In embodiments of the present invention, due in first time period there is no INVITE message with media stream associations, can be
Second time period and continue to search whether same caller initiates session in the third period.
Do not include caller ID in Media Stream, first uses the second time period and the INVITE message of third period of signaling plane
It is associated, if second time period is identical with two INVITE message caller IP address/port numbers in the third period, and caller
ID is identical, then second time period and the INVITE message of third period it is corresponding be same caller, thus it is believed that when second
Between the first Media Stream of first time period between section and third period and the INVITE message of second time period be same master
It cries, the INVITE message with the third period is same caller.
In this case, the caller ID of the INVITE message of second time period can be backfilled to the first Media Stream.
Other steps of the present embodiment are similar to previous embodiment step, and this embodiment is not repeated.
The method of association process provided in this embodiment, in order to avoid accidentally should not be with by the INVITE message of second time period
First media stream associations of first time period, first will be using the second time period and the INVITE message of third period of signaling plane
It is associated, if being successfully associated, after being determined as same caller, then by the first Media Stream of first time period and second time period
INVITE message is associated, if being successfully associated, so that can determine is same caller.
On the basis of the above embodiments, the method for the association process that further embodiment of this invention provides, first matchmaker
Body stream includes start time point, and the SIP process includes multiple sip messages, correspondingly, if the IP address of the first Media Stream and the
The IP address of the INVITE message of two periods is consistent, then the caller ID of the INVITE message of second time period is backfilled to first

It determines in the corresponding SIP process of the INVITE message with the presence or absence of BYE message；
BYE message if it exists, using the time point of BYE message as the end time of the road session.
Optionally, after the INVITE message of second time period and the first media stream associations are successful, it is believed that the INVITE message
Session all the way corresponding with the first Media Stream, or think the corresponding session of the INVITE message, it is corresponding with the first Media Stream all the way
The voice quality of session is similar, all can carry out voice quality to the session all the way of the INVITE message and the first media stream associations and comment
Estimate.
Optionally, carry out Speech Assessment need to determine session all the way at the beginning of and the end time.
It is that INVITE message is initiated in caller at the beginning of session all the way, then using the time point of INVITE message as the road
At the beginning of session.
The end time of session is the BYE message of SIP call flow all the way, and before step 11, acquisition is entire SIP
Call flow obtains the sip message of SIP process.
After the INVITE message is successfully associated, to the SIP process of the INVITE message being successfully associated
Other sip messages are determined according to time resolution with the presence or absence of BYE message in the corresponding SIP process of the INVITE message, if depositing
In BYE message, using the time point of BYE message as the end time of the road session.
The time point of the last one data packet of Media Stream is the end time of medium surface information, in practical application, is being adopted
In the step of collecting SIP call flow, it is possible to be lost BYE message, then can not determine the accurate end time, but according to history
Empirical data can determine, when not retransmiting Media Stream, will send BYE message in a short period of time, therefore can be by Media Stream
End time of the time point of the last one data packet as session all the way.
BYE message if it does not exist, then using the end time of Media Stream as the end time of the road session.
At the beginning of determining session all the way and after the end time, speech quality evaluation can be carried out to the session.
Other steps of the present embodiment are similar to previous embodiment step, and this embodiment is not repeated.
