Data management interface, discharges described circuit domain system logic node serial number resource, and is compiled by described circuit domain system logic node
Number corresponding data management chnnels of resources is set to idle condition.
Step 605, to the return of described media gateway controlling equipment for responding the response message of described SUB signaling, and on
The medium stream information of report statistics.
With reference to Fig. 7, below just use as a example by IMS Colorful Ring Service by circuit domain user, in detailed description CS territory, user is such as
What realizes the detailed process of Ring Back Tone service.
Step 1, after the dialing of calling subscribe's UE1 off-hook, MGCF receives the ISUP initial address message of calling switchboard
(IAM), then to the CSAS of MS, (Circuit Switched Domain Access System, circuit commutative field accesses system
System) send Add message, wherein said ADD message includes:
In CSAS, create a new context, and in context, add Incoming relaying and RTP terminal number, and will
The Mode of RTP is set to Receiveonly, and arranges voice compression algorithm；
Wherein, G.711A described voice compression algorithm can use, G.711U, G.729, the compression algorithm such as 324M；
Step 2, described CSAS is RTP Resources allocation RTP1 of required Add, and to described MGCF response Reply message, its
In, described Reply message includes: the IP address of described RTP1, the voice compression algorithm of employing and RTP port numbers etc.；
Step 3, described MGCF distributes calling UE 1SDP offer；INVITE request is route after CRBT application server
To called subscriber UE2；
Described called subscriber's UE2 ring, sends 180 responses, and carries the UE2SDP of corresponding described UE1SDP offer
answer；
Step 4, CRBT application server is to MRF (Media Resource Function, the media resource function) Shen of MS
Please CRBT media resource, CRBT application server route 180 is responsive to described MGCF, carries described MRBT SDP in response
answer；
Step 5, sends Mod message to the CSAS of MS after described MGCF, arranges far-end RTP address and port numbers, voice pressure
Compression algorithm etc.；
Step 6, described CSAS returns response Reply message to described MGCF,；
Step 7,180 responses are converted to ACM by described MGCF, and (Address Complete Message, address disappears entirely
Breath), it is sent to described UE1；Described UE1 confirms described 180 responses by PRACK；PRACK is responded by described UE2；
Step 8, CRBT application server sends INFO request instruction MRF coloring ring back tone playing；
Step 9, after described called UE 2 off-hook, described CRBT application server uses UPDATE to initiate media more to MGCF
Newly；The most described CRBT application server sends BYE and asks described MRF, terminates polyphonic ringtone playing；
Step 10, described MGCF sends MOD message to CSAS, its Mode is revised as SendReceive；
Step 11, described CSAS returns Reply message to described MGCF；
Step 12, described calling UE 1 and described called UE 2 start call；
Step 13, described calling UE 1 or described called UE 2 on-hook terminate call；
Step 14, described MGCF sends SUB message to CSAS, discharges called relaying and RTP；
Step 15, CSAS returns Reply to MGCF, wherein reports the Media Stream statistical information of calling,
Wherein, described Media Stream statistical information includes: media keep duration, calling party, callee, the filename of broadcasting
Title information.
By the embodiment in present specification, following technique effect at least can be realized:
One, by the process of ADD signaling, circuit domain and the distribution of link terminal resource and circuit domain passage, RTP are solved
Passage and voice ALT-CH alternate channel open problem；And ins and outs involved in above-mentioned processing procedure are set such as: RTP receives and dispatches mould
Formula, compression algorithm pattern, packaging time length, network jitter scope and abnormality alarming attribute, the relevant parameter such as procotol standard, reach
Arrive multimedia information stream on passage, be transmitted preparing and arranging for corresponding parameter detail the technique effect of preparation.
Two, by the process of MOD signaling, the IP address of SLN and RTP of RTP terminal, port numbers, VOIP module are solved
The offering question of the port attribute of correspondence, distal compaction algorithm, far-end packaging time length etc., has reached each mould in media server
The technique effect of corresponding logic interfacing position is obtained between block.
Three, by the process of SUB signaling, solve the circuit domain passage corresponding to the SLN of RTP and the SLN of circuit domain,
RTP passage and the closing problem of voice ALT-CH alternate channel, provide channel resource and circuit domain relay resource for media services next time
Deng.
Obviously, those skilled in the art can carry out various change and the modification essence without deviating from the present invention to the present invention
God and scope.So, if these amendments and modification to the present invention belong to the model of the claims in the present invention and equivalent technologies thereof
Within enclosing, then the present invention is also intended to comprise these change and modification.
