Description

Called party inter-vibrator multimedia display method based on direct connection MGCF node AS

Technical Field

The invention relates to the technical field of communication exchange, in particular to a called party inter-vibrator multimedia display method based on a direct connection MGCF node AS.

Background

The MGCF is called AS media gateway control function, which is translated into a multimedia gateway control unit, and an important functional unit in the core network IMS subsystem is commonly accessed to external AS service for realizing various call functions because of good signaling and media control conversion and protection capability.

In recent years, communication technology has been rapidly developed, and switching technology belonging to the field of communication cores has also been vigorously developed. The combination of increasingly sophisticated intelligent voice technology, video communication technology and switching technology has also produced good chemical effects. The application of the new exchange technology is rapidly developed towards 2 directions. Firstly, intelligent customer service and intelligent outbound products are generated by organically integrating an intelligent voice technology and an exchange technology, and the intelligent customer service and the intelligent outbound products are used AS AS services based on direct connection core network MGCF nodes and are rapidly applied to a large-scale telephone notification scene. Secondly, the video communication technology and the exchange technology are organically integrated, so that 5G video customer service and 5G video seat are generated, and experience perception of conversation products is greatly enriched.

The intelligent outbound product is an AS service important application direction of a direct connection core network MGCF node based on a soft switching platform and an intelligent voice technology, is more and more widely applied in actual life, and the scenes of the main service are generally government affair notification, arrearage reminding, voice investigation and the like. Intelligent outbound product platforms tend to call out a large number of phones in a short time, thanks to the automation and good concurrency capabilities of the system. And after the call is made, the answering rate of the call is one of the most important factors affecting the answering effect. In order to improve the answering rate, the following methods are available in the prior art.

1. The mobile phone terminal manufacturer is used for carrying a third party marking function. The method is realized by the principle that a terminal manufacturer dials an app to have a code number recognition function, marks are marked on numbers when calling in and calling out, such as marks of express take-out, marketing advertisements, government telephones and the like, so that a strange number marking function is realized.

2. An operator side flash business card service is used. After the calling user opens the service, the operator network side captures the calling user calling signaling, analyzes the called information, and at the moment of called ringing, sends the flash information to the called, the flash information can directly jump out and be displayed on the called mobile phone.

The two methods have the advantages that the outgoing call answering rate is improved to a large extent, but the two methods have certain defects. Firstly, the display content is not rich, no matter a third party marking function or a flash business card service is used, the information transmitted to the called party is only text information, and the form is single; secondly, the mobile phone terminal manufacturer has a third party marking function, if the mobile phone terminal manufacturer wants to cover all called users, all terminal manufacturers or third party application manufacturers need to be coordinated, and the workload is huge; third, implementing both of the above functions involves having to resort to third party resources and paying third party costs.

With the development of technology, MGCF nodes in the core network gradually have video media capabilities, that is, MGCF nodes can already perform transparent transmission of video media, so that the underhung AS service also has video media capabilities, and thus, the AS has the possibility of more rich media applications. It should be noted, however, that the conventional MGCF node does not provide video channel capability by default at the time of access, and thus there is a need for a method for enabling the MGCF node to adjust to provide this capability in real time.

Therefore, there is a need for a product technology of a called party inter-vibrator multimedia display method that has a richer display form, lower cost, and no third party resource, is adapted to a direct-connection MGCF-AS, and is used for realizing multimedia display during called ringing, improving call efficiency and user experience, and more efficiently utilizing the direct-connection MGCF-AS call resource.

The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings of the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

A called inter-vibrator multimedia display method based on direct connection MGCF node AS includes the following steps:

the AS service module initiates a voice call request and establishes a voice call request and a preamble voice channel; an AS service module initiates a video media resource reservation request to confirm whether the MGCF node and a called side can reserve video media resources; after receiving the video media resource information of the opposite side, confirming the video media resource reservation information, and in the ringing stage, the AS service module initiates a unidirectional video media negotiation function to the MGCF node and the called side, and after media negotiation is completed, the called side unidirectional video channel is opened, and the AS service module can initiate video or picture pushing;

after the unidirectional video channel is established, a request can be initiated to a calling video picture media library of the cloud by a picture and video pushing function module, and video or picture storage is completed to form a cache file; after the complete file is obtained, the AS service module plays the video or the picture to the called side, so that the pushing flow of the video or the picture is realized;

at this time, intelligent voice fallback processing is carried out, if the called side is connected, the called side initiates a signaling request for closing the unidirectional video channel, and stops sending video streams; if the called side is not connected, the core network side initiates a signaling request for closing the unidirectional video channel and stops sending the video stream.

The called inter-vibrator multimedia display method based on the direct connection MGCF node AS can realize the called inter-vibrator multimedia display with richer display forms, lower cost and no help of third party resources. All call control signaling from CS users points to MGCF, which is responsible for protocol conversion between ISDN user part or bearing irrelevant call control and SIP protocol, and transmits session to AS service module of core network IMS), namely BtoC mode, and realized by signaling layer, after AS service module initiates call request, signaling interaction mode containing specific resource reservation informs media requirement, and builds one-way video channel of called side; after successful pushing of pictures and videos, a voice fallback negotiation function before called connection and a negotiated telephone traffic state analysis and follow-up action function are designed. Before the called user continues, negotiating MGCF node to obtain video media resource support and establishing video call channel of the called user; the method and the device can accurately identify the answering state of the user, carry out fallback negotiation according to different states, and carry out high-efficiency control on the services.

In the implementation, if the AS service of the direct connection core network MGCF node needs to have the function of multimedia presentation during the called ringing when a call is initiated, the audio/video negotiation module is required to have the function of video media resource reservation application and the function of unidirectional video media negotiation before answering after the called ringing, the audio/video play module is required to play the audio/video media after the unidirectional video channel negotiation is successful, and the audio/video negotiation module is required to carry out audio intelligent fallback according to the telephone traffic state and confirm whether the on-hook is required or not in the state that the called is connected or not.

If the AS service of the direct connection core network MGCF node is required to provide the multimedia display service during the ringing period of the called party, the signaling negotiation function module firstly requires the AS service call of the direct connection MGCF, and after the call is initiated, the user starts ringing moment, firstly can initiate a video resource application request to the MGCF, and can initiate the establishment service of the unidirectional video channel to the called party. Secondly, after the unidirectional video channel is established, the picture and video pushing function module can initiate a request to a calling video picture media library of the cloud, complete video or picture storage and quickly form a cache file. After the complete file is obtained, the AS service side needs to play the video or the picture to the called side, so that the pushing flow of the video or the picture is realized. And finally, according to whether the user answers or not, performing intelligent audio fallback operation and confirming whether the user needs to hang up or not.

Therefore, the method comprises the following specific steps of 3 processing flows of a service process for establishing a one-way video channel at the called side before connection, a pushing process for pictures and videos and an intelligent voice fallback processing process.

The one-way video channel establishment service process of the called side before connection mainly comprises an AS service initiation voice call sub-process, a video resource reservation sub-process and a one-way video negotiation sub-process; in the sub-flow of initiating voice call by AS service, the AS service module initiates a voice call request, and establishes a voice call request and a preamble voice channel, and specifically includes the following steps:

In step 1.1, when the AS service module initiates a voice call request, an Alert-Info: < url: service: crs > is added in the header field of the call signaling (SIP, session Initiation Protocol, which is a signaling control protocol of an application layer, for creating, modifying and releasing sessions of one or more participants, which may be Internet multimedia conferences, IP phones or multimedia distribution; adding P-Early-Media to supported, the process tells the core network that such Media service requests need to be transmitted through; meanwhile, in a media negotiation section (SDP, session description protocol, used for media negotiation between two session entities, and agreed, belonging to a signaling language family, in text or character description form) of a call Signaling (SIP), a voice media request needs to be normally initiated to a core network.

In the video resource reservation sub-process, the AS initiates a video media resource reservation request from the AS service module to confirm whether the MGCF node and the called side can reserve video media resources, and specifically includes the following steps:

In step 2.1, when the AS service module initiates a video media resource reservation request, a conf operation is performed on a counterpart resource in a media negotiation Section (SDP), specifically, a=conf: qos remote sendrecv is added in the SDP, so AS to confirm whether the MGCF node and the called side can have video resource reservation. After receiving the video resource information of the opposite party, the subsequent flow can be initiated.

In the unidirectional video negotiation sub-flow, in the ringing stage, the AS service module initiates a unidirectional video media negotiation function to the MGCF node and the called side, and specifically comprises the following steps:

In step 3.1, when the AS service module initiates the unidirectional video request, the unidirectional video request is added with a=sendonly in the video information portion of the media negotiation portion (SDP) of the Signaling (SIP), and profile-level-id=42c01f.

The pushing process of the pictures and the videos mainly comprises a cloud request video or picture information sub-process and an AS service video or picture playing sub-process. The cloud request video or picture information sub-process comprises the following steps: after the unidirectional video channel is established, a request can be initiated to a calling video picture media library of the cloud by a picture and video pushing function module, video or picture storage can be completed, and a cache file can be quickly formed; it should be noted that the requested video file is generally a picture video which is set by the calling party, and the AS service module and the cloud end need to keep the high-speed bandwidth smooth, so that the video or the picture can be cached in the shortest time, and the user experience is improved.

The AS service playing video or picture sub-process includes: after the complete file is obtained, the AS service module plays the video or the picture to the called side, so that the pushing flow of the video or the picture is realized; it should be noted that the completion of the video picture is completed after the video picture is played and the buffer is checked, so that the success of pushing is ensured.

The intelligent voice fallback process mainly comprises a call state judging sub-process and a voice fallback sub-process. In the voice fallback sub-flow, if the called side is connected, the called side initiates a signaling request for closing the unidirectional video channel and stops sending the video stream; if the called side is not connected, the core network side initiates a signaling request for closing the unidirectional video channel and stops sending the video stream; the method specifically comprises the following steps:

if the called side is connected, the called side initiates a signaling request for closing the unidirectional video channel to the AS service module through the core network, the AS service module responds to the signaling request, replies the signaling for closing the video channel, stops sending the video stream, and the call center responds to the signaling and switches to voice so AS to perform normal call; if the called side is not connected, the core network side initiates a signaling request for closing the unidirectional video channel to the AS service module, the AS service module responds to the signaling request, replies to close the video channel signaling and stops sending video streams, and the AS service module initiates a hang-up request, releases the telephone traffic resource, and the call center responds to the signaling, switches to voice and hangs up the call center.

If the called side is connected, the called side initiates a signaling request for closing the unidirectional video channel and stops sending the video stream; if the called side is not connected, the core network side initiates a signaling request for closing the unidirectional video channel and stops sending the video stream; the method for judging whether the called side is connected is a call state judging sub-process, and comprises the following steps:

Under the normal state, if the core network and the called user side complete the service process of the unidirectional video channel establishment of the called side and the process of pushing pictures and videos before connection, the user side belongs to the normal state, so that the on/off state of the called user exists.

In this embodiment, the answer state of the called side is judged and recorded by an answer state UPDATE signaling (UPDATE signaling) detection sub-module; and the answering state UPDATE signaling (UPDATE signaling) detection submodule judges whether the state is on or not according to the reflection information of the return signaling, and changes to different voice fall-back sub-flow processes according to the judging result.

The first module in the method is to build the service function of the called side video channel establishment before connection of the AS service module adapted to the direct connection MGCF, including the voice call origination, the voice channel pre-establishment flow, the video resource media reservation application and the voice-to-video channel establishment flow. The AS service module voice call initiation and voice channel pre-establishment flow is basic voice channel establishment capability, after establishment is completed, a called side returns a response Session Progress (183 Session Progress for prompting Progress information of a Session establishment, and a sentence, a header field or a message body of a Reason for the expression of a Reason-Phrase can be used for prompting more message information of call Progress) signaling to enter a ringing stage. After entering the ringing phase, the called party starts ringing. At this time, the MGCF node defaults to have voice resources, and expands the core network video media resources by applying for video media resource reservation to the MGCF node, and after the reply is obtained, an audio-video-raising request is initiated to the MGCF node side and the called side at this time, and if the called party satisfies the video call capability, a video channel can be established before the called party continues.

The second method module is to build a called on/off voice intelligent fallback module. After the pre-call unidirectional video channel is established, the AS service module carries out successful pushing of pictures and videos, at the moment, the AS service module and the user mobile phone coexist in the voice and unidirectional video channel, after entering the next state, the unidirectional video channel needs to be closed, and the accurate control of telephone traffic is carried out according to the telephone traffic state, so that the call resource waste is reduced. The AS service module builds a detection sub-module of answer state UPDATE signaling (UPDATE signaling) for detecting a Reason field in the UPDATE signaling to confirm the answer state of the user. If the AS service module detects that the called user is connected through voice, the AS service module responds to a degradation signaling request of the called user which is transmitted to the MGCF, replies to close the video channel signaling, and stops sending the video stream; if the AS service module detects that the user is not connected, the AS service module responds to the resource degradation request which is transmitted to the MGCF after the called party is not connected, replies to close the video channel signaling, stops sending the video stream, synchronously closes the telephone traffic, and reduces the waste of the call resources of the AS service module.

The invention realizes a product technology of a called party inter-vibrator multimedia display method which has richer display form, lower cost and no help of third party resources, is suitable for directly connecting with the MGCF-AS, is used for realizing multimedia display during called ringing, improves the calling efficiency and the user experience, and more efficiently utilizes the calling resources of the directly connecting MGCF-AS.

The invention provides a novel and efficient media and information push service before call connection, which brings innovation and formal enrichment. The traditional push information before call connection is to use a third party marking function of a mobile phone terminal manufacturer and use a flash business card service at an operator side. The mobile phone terminal manufacturer can realize the defects that the information form is single and all terminal manufacturers need to be coordinated together by the aid of the third-party marking function, the information form is single by using the service of the carrier side flash business card, and the problem of internet cost settlement is solved by transmitting flash information across networks by the carrier. The invention creatively provides a multimedia display method and a system during called ringing based on an AS service module of a direct connection MGCF, which have the following advantages:

(1) The AS service module based on the MGCF node in the direct connection core network is realized and innovatively applied to the B-C mode. After the call is initiated, after the voice channel is established, the video media resource capacity before the called connection is activated by a video resource reservation application mode, and the advantage of the MGCF node after the video resource is provided is successfully exerted.

(2) Native signaling, future high coverage; is realized through standard call control SIP signaling, so the method has wide popularization in the future.

(3) The method has the sub-module based on detection of the answering state UPDATE signaling (UPDATE signaling) and is more efficient. And the receiving state of the called party is obtained and corresponding operation is carried out by analyzing the UPDATE signaling request information, and the call is directly hung up for the non-receiving telephone traffic of the called party, so that the call resource consumption is greatly reduced.

(4) The information pushing form is rich, so that the cost is saved; because the video information can be pushed, the richness of the form is greatly improved, the audio, video, image and text can be downwards compatible or the omnibearing display of the audio, video, image and text can be realized, the information displayed on the user side is more vivid, and the user experience is improved and the better propaganda effect is achieved. Compared with the mobile phone terminal manufacturer with a third party marking function and using the operator side flash business card service, the mobile phone terminal manufacturer does not need to coordinate extra mobile phone terminal manufacturer to carry out modification marking by using standard signaling, and does not need to purchase information pushing resources among operators additionally, so that the economic effect is better.

The invention realizes a product technology of a called inter-vibrator multimedia display method which is more abundant in display form, lower in cost and free of third party resources and is suitable for direct connection with MGCF-AS by controlling the interaction of video media signaling before conversation, is used for realizing multimedia display during called ringing, improves the calling efficiency and user experience, and more efficiently utilizes the calling resources of the direct connection with MGCF-AS. At present, although there are some researches and preliminary applications related to video display of incoming call information on the market, most of the applications are display performed when two mobile phone users (C-C) dial each other, and the invention well compensates for the point like multimedia display during the period of calling request to user side (B-C mode) which is adapted to direct connection with MGCF-AS to realize called ringing.

The invention provides a method for activating media resources of MGCF in core network during called ringing and a use sequence, which enables an AS service module directly connected with MGCF node to have a multimedia push function during called ringing.

The invention innovatively establishes a detection sub-module of the answering state UPDATE signaling (UPDATE signaling) for judging and recording the answering state of the user. Under the normal state, if the large network and the user side complete the service process of establishing the unidirectional video channel of the called side and the pushing process of pictures and videos before connection, the user side belongs to the normal state, so that the user on/off state exists. And judging the state according to the return signaling, and turning to different voice fall-back sub-flow processes. The user is connected to keep talking normally, the user is not connected, the AS service module is directly hung up, and the utilization rate of the telephone traffic resource channel is greatly improved.
