Abstract
A method for playing multimedia through H. 248 protocol includes adding play end-point on media resource processing unit by media resource control unit to set up playing channel and then indicating media resource processing unit to play multimedia by media resource control unit. The system used for realizing said method is also disclosed.
Description
Technical field
The present invention relates to communication field, especially relate to a kind of H.248 method and system of agreement realization multimedia of passing through.
Background technology
MGC (Media Gateway Controller, Media Gateway Controller) and MG (Media Gateway, media gateway) are two key members among the NGN (Next Generation Network, next generation network).MGC is responsible for CCF, and MG is responsible for the service bearer function, realize by this calling out separating of control plane and service bearer plane, thus abundant shared network resource, simplified apparatus upgrading and professional expansion reduce development and maintenance cost greatly.
MGCP is the main agreement of communicating by letter between MG and the MGC, present widely used (the Gateway Control Protocol that has H.248/MeGaCo, gateway control protocol) and two kinds of agreements of IMGCP (MediaGateway Control Protocol, MGCP).
With agreement H.248 is example, and the various resources on the MG are terminal (Termination) by abstract representation.Terminal is divided into physical terminal and ephemeral terminations again, the former represents some physical entities with semipermanent existence, TDM passage etc. for example, the public resource that on behalf of some provisional application, the latter discharge with the back, RTP (Real-time Transport Protocol, RTP) stream etc. for example.Combination between the terminal is context (Context) by abstract representation.Context can comprise a plurality of terminals, thereby describes the correlation of terminal room with topology (Topology).
Based on this abstract model of agreement, in fact continuing of calling be exactly to terminal and contextual operation.This operation is finished by the order between MGC and the MG (Command) request and response.Command type comprises interpolation (Add), revises (Modify), deletes (Subtract), moves (Move), audit value (AuditValue), auditability (AuditCapabilities), circular (Notify), service change (ServiceChange).Command parameter is also referred to as descriptor (Descriptor), is classified as attribute (Property), signal (Signal), incident (Event), statistics (Statistic).Parameter with professional correlation polymerization in logic becomes bag (Package).
The method of advanced media server bag (Advanced Media Server Packages) definition has:
(1) plays sound bite: can indicate the position of voice snippet by URI, can indicate parameters such as the number of repetition of playing voice snippet, the blanking time between each, volume, speed;
(2) collect the digits: playing alert tones and DTMF collect the digits alternately;
(3) recording: sign or the deposit position that voice recording can return recording file carried out in the position according to indication;
(4) voice document deletion action.
Development along with the medium treatment technology, people no longer are satisfied with voice call, the video multimedia communication is accepted by more and more people, on communication network, provide the multimedia solution to become the problem that people pay close attention to, expand the agreement of original speech network, support multimedia service, become the emphasis of research.The present invention proposes a kind of expansion H248 agreement, support multi-media player function.
Summary of the invention
The technical problem to be solved in the present invention is to overcome the deficiency that above-mentioned prior art exists, a kind of H.248 method and system of agreement realization multi-media recording of passing through are provided, are used for satisfying the demand of media resource controlling device control medium processing device play multimedia files.
For solving the problems of the technologies described above, the invention provides the method that a kind of H.248 agreement realizes multi-media player function, may further comprise the steps:
(1) media resource controlling device increases the broadcast end points on media resource processing arrangements, sets up and plays passage; And
(2) media resource controlling device indication media resource processing arrangements carries out multimedia.
Further, indication described in the step (2) comprises position that needs played file and the Control Parameter that Media Stream is play, the form of the positional information of described played file comprises local file, file that this locality contains the path and the file on the remote server, and described Play Control parameter comprises broadcasting time, plays interval, broadcasting speed, broadcast sound volume, video image format, image play frame rate, image playback rate, file playing position and directly finish broadcast etc.
Further, described step (2) further comprises step:
(3) media resource controlling device indication media resource processing arrangements carries out multimedia with the file of appointment to the end points of appointment;
(4) media resource processing arrangements finds corresponding file according to indication, reads the attribute information of depositing Media Stream in the file;
(5) media resource processing arrangements reports media resource controlling device to corresponding response message; And
(6) the media resource processing server carries out multimedia.
Further, in the described step (3), media resource controlling device issues the Play Control order to each code stream, and controls playing number of times, broadcast interval, broadcasting speed, broadcast sound volume, video image format, image play frame rate, image playback rate, file playing position reach and directly finish broadcast etc.
Further, attribute information comprises Media Stream type of coding, media stream rate, Media Stream sample rate etc. in the described step (4).
Further, also comprise step:
(7) finish playing, media resource processing arrangements reports media resource controlling device playing the result.
Further, if play failure, the result who reports also comprises the failure cause return code.
The present invention also provides a kind of H.248 agreement to realize the system of multi-media player function, comprise media resource controlling device and media resource processing arrangements, described media resource controlling device increases on media resource processing arrangements plays end points, set up and play passage, described media resource controlling device sends multimedia and is indicated to described media resource processing arrangements.
Further, described media resource processing arrangements finishes playing back transmission broadcast result to described media resource controlling device.
The present invention has following useful effect: utilize method and system provided by the invention, play end points by on media resource processing arrangements, increasing, set up and play passage, can realize the operation of medium control device indication medium processing device play multimedia files, the support that provides for the ability that under scene, realizes play multimedia files by the control of agreement H.248 media resource apparatus, make the user not only hear playback, and can see image, improved user's business experience.
