The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
Furthermore, the drawings are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and thus a repetitive description thereof will be omitted. Some of the block diagrams shown in the figures are functional entities and do not necessarily correspond to physically or logically separate entities. These functional entities may be implemented in software or in one or more hardware modules or integrated circuits or in different networks and/or processor devices and/or microcontroller devices.
In the related art, the existing mobile network and standard only support the communication of both parties by adopting the same media type, but do not support the automatic conversion between the media types such as text, voice, sign language video and the like.
In this exemplary embodiment, in order to solve the technical defects existing in the prior art, a multimedia data conversion method is provided first, which can be applied to real-time communication between users with special requirements such as aphasia/language disorder, aphasia/hearing disorder, blindness, etc. by adopting different media types. Referring to fig. 1, the multimedia data conversion method may specifically include:
step S11, receiving a first call request of a calling terminal; the first call request comprises calling terminal media type information and called terminal identity information;
step S12, determining the corresponding convertible media type according to the calling terminal media type information, generating a second call request based on the convertible media type and sending the second call request to the called terminal;

and step S14, generating first call response information based on the called terminal media type information and sending the first call response information to the calling terminal so as to construct a media conversion link between the calling terminal and the called terminal.
In the method for converting multimedia data provided in this example embodiment, after receiving a first call request uploaded by a calling terminal through a core network, a corresponding convertible media type may be determined according to calling terminal media type information included in the first call request, and then a second call request may be generated based on the convertible media type and sent to the called terminal. Then, second call response information which is fed back by the called terminal and comprises called terminal media type information can be received; and generating first call response information based on the called terminal media type information and sending the first call response information to the calling terminal so as to construct a media conversion link between the calling terminal and the called terminal. So that the calling terminal and the called terminal can use the media conversion link established in the core network to communicate in real time by using different types of media data.
Hereinafter, each step of the multimedia data conversion method in the present exemplary embodiment will be described in more detail with reference to the accompanying drawings and examples.
In step S11, a first call request of a calling terminal is received; the first call request comprises calling terminal media type information and called terminal identity information.
In this example embodiment, the above-described method may be performed by a multimedia service communication system; the multimedia service communication system may be arranged in a core network. For example, the calling terminal and the called terminal may be intelligent terminal devices, for example: and intelligent terminal equipment such as a mobile phone, a tablet personal computer, an intelligent bracelet, an intelligent watch and a computer. When a calling terminal initiates a first call request to a called terminal, a first core network accessed by the calling terminal receives the first call request, forwards the first call request to a multimedia service communication system, and processes the first call request by the multimedia service communication system. The first call request can be used as a media negotiation signaling from the calling terminal to the called terminal, and is used for negotiating usable and converted media types and formats with the called terminal; and establishes a communication link between the calling terminal and the called terminal. The first call request may include media type information of the calling terminal and identity information of the called terminal; the calling terminal media type information may be a media type selected by the calling terminal user. For example, for an impaired person, the media type of his choice may be text, or video for presenting sign language. Of course, in some exemplary embodiments of the present disclosure, the call request described above may also include other parameters based on existing protocols, such as caller identity information, IP information, key information, and so forth.
In step S12, a corresponding switchable media type is determined according to the calling side media type information, and a second call request is generated based on the switchable media type and sent to the called terminal.
In this example embodiment, for a multimedia service communication system, conversion mapping relationships corresponding to different media types may be stored locally. For example, one media type corresponds to at least one media type in a different format that can be converted. After receiving the first call request, the calling terminal media type information contained in the first call request can be firstly extracted, then the corresponding at least one convertible media type which can be converted is determined according to the calling terminal media type information, and a second call request is generated as negotiation signaling which can be identified and processed to the called terminal.
For example, the current calling side media type a, the corresponding switchable media type B, C, D, then a second call request is generated according to the switchable media type B, C, D and sent to the called terminal. For example, a second call request may be generated based on the switchable media type B, C, D, i.e. in a negotiation signaling, containing user selectable media types; and, in the negotiation signaling, the request information of three formats corresponding to the switchable media type B, C, D may be received. For example, the above-mentioned convertible media types are text format, video format, and audio format, respectively, and then a negotiation signaling may include request information in three formats; for example, the request information may be caller identification information such as telephone numbers, nicknames, names, etc. In addition, the calling side media type a may be included in the second call request.
Alternatively, in some exemplary embodiments, after determining the switchable media type B, C, D corresponding to the current calling end media type a, negotiation signaling of three different media formats may also be generated according to the switchable media type B, C, D, and sent to the called terminal synchronously, so that the called user may process the second call request in the interaction interface of the called terminal device.
When the specific media type usable by the user at the called terminal side is not determined, after the convertible media type corresponding to the media type of the calling terminal is determined, respectively sending a second call request to the called terminal in different convertible media formats, and displaying the second call request in different media formats in an interactive interface of the called terminal, for example, respectively displaying the second call request in text, audio and video synchronous directions, so that the user at the called terminal side can select the media type usable by the user according to actual conditions. For example, for a user with visual impairment, an audio format media type may be selected according to a second call request for audio playback; or, for the user with hearing impairment and without understanding to use sign language, selecting the media type in audio format as the called media type according to the second call request displayed by the text; alternatively, for users with hearing impairment, a media type in video sign language format may be selected based on a second call request for video sign language play.
Further, in some exemplary embodiments, the determining a corresponding switchable media type according to the calling side media type information includes:
and inquiring a target database according to the identity information of the called terminal to determine the preset called terminal media type information of the called terminal so as to generate the second call request based on the preset called terminal media type information.
In particular, for multimedia service communication systems, a target database may also be configured, which may store media type information pre-configured by a particular user; or may be media types commonly used by a particular user, as counted from historical call data. The identity information of the user, and corresponding media type information, may be stored in the target database. For example, after the multimedia service communication system receives a call request for a called terminal, the target database may be queried first according to identity information of the called terminal in the call request; if the target database is queried that the preset media type of the called terminal exists, a second call request can be sent to the called terminal in a corresponding media format according to the query result, so that the called terminal can directly process the call request. Or if the preset media type corresponding to the called terminal is not queried in the target database, determining the corresponding convertible media type according to the calling terminal media type, generating a second call request based on the convertible media type, and sending the second call request to the called terminal.
In step S13, receiving second call response information fed back by the called terminal; wherein the second call response information includes called-side media type information.
In this example embodiment, after the user at the called terminal agrees to make a call and selects a media type, the user at the called terminal determines the media type as the called terminal media type and feeds back the media type to the calling terminal. For the multimedia service communication system, the second call response information fed back by the called terminal can be received through the second core network accessed by the called terminal. Wherein, the acknowledgement information in the second call response information may be produced in the called-end media type. The second core network and the first core network may be the same core network; i.e. the calling terminal and the called terminal access the same core network.
Furthermore, in some exemplary embodiments, for a multimedia service communication system, when receiving the second call response information fed back by the called terminal, the method further includes: establishing a media conversion corresponding relation according to the calling terminal media type information corresponding to the calling terminal and the called terminal media type corresponding to the called terminal; the media conversion corresponding relation comprises terminal identity information and media type information. The established temporary media conversion correspondence may be used for format conversion of the media stream in a subsequent communication process.
In step S14, first call response information is generated based on the called-side media type information and is sent to the calling terminal, so as to construct a media conversion link between the calling terminal and the called terminal.
In this example embodiment, for the multimedia service communication system, the second call response information may be received, converted into a calling side media type used by the calling terminal, and the first call response information may be generated; the first call response information may include response confirmation information of the calling side media type. After the first call response information is issued to the calling terminal, the media type negotiation process can be completed, and a media conversion link between the calling terminal and the called terminal is established through a core network and a multimedia service communication system and is used as a real-time communication channel between the calling terminal and the called terminal.
In this example embodiment, the method may further include: and receiving first media data of a calling terminal media type sent by the calling terminal, converting the first media data into second media data of a called terminal media type, and sending the second media data to the called terminal.
In this example embodiment, the method may further include: and receiving third media data of the called terminal media type sent by the called terminal, and converting the third media data into fourth media data of the calling terminal media type.
Specifically, after the media type negotiation is successful and the media conversion link is established, the calling terminal and the called terminal can respectively send media data streams with corresponding formats to the opposite terminal. For example, the calling terminal may transmit first media data in the form of a calling-side media type and first transmit to the multimedia service communication system through the core network. The multimedia service communication system encodes the first media data, converts the first media data into second media data corresponding to the called terminal media type format, and sends the second media data to the called terminal, so that the second media data can be directly displayed at the called terminal. Similarly, the multimedia service communication system may receive the third media data in the called media type format sent by the called terminal to the calling terminal, and perform encoding and decoding and format conversion on the third media data, and convert the third media data into fourth media data in the calling media type format, so that the user at the calling terminal side may directly read the fourth media data at the calling terminal.
In some exemplary embodiments, when the first media data, the second media data comprise real-time media data, non-real-time media data, the method further comprises: and when the data packet corresponding to the non-real-time media data does not meet the real-time media packing interval requirement, sending a preset white noise mute packet to keep the media conversion link alive.
Specifically, when one end uses non-real-time media and the other end uses real-time media in the calling terminal and the called terminal; for example, the calling terminal adopts an audio format, and the called terminal adopts a text format; if the non-real-time media information is too little to meet the real-time media packing interval requirement, a preset white noise mute packet is sent to keep the real-time media channel alive and improve the hearing comfort of the user. For example, the preset packing interval is 20ms, and the called terminal adopts a text format for input, so that the input speed is slower; when the interval of the data packet of the text format data uploaded by the called terminal is greater than 20ms, the multimedia service communication system can send default white noise mute data to the calling terminal, so that the media conversion link between the calling terminal and the called terminal is kept in an active state.
In the present exemplary embodiment, a multimedia data conversion method applied to a terminal device is provided. Specifically, the method can be applied to the called side terminal equipment; referring to fig. 2, the method specifically may include:
step S21, receiving a second call request; wherein the second call request includes: calling terminal identity information and convertible media types;
step S22, the media type information of the called terminal is determined in response to the selection of the convertible media type;
step S23, generating second call response information according to the called terminal media type information and feeding back to the multimedia communication service system, wherein the multimedia service system is used for generating first call response information according to the second call response information and sending the first call response information to the calling terminal so as to construct a media conversion link between the first call response information and the calling terminal.
In this example embodiment, for the called terminal, a second call request issued by the multimedia service communication system in the core network may be received; the second call request is generated after the multimedia service communication system converts the first call request sent by the calling terminal.
After the called terminal receives the second call request, the second call request can be respectively displayed in a format of a convertible media type in an interactive interface of the called terminal. For example, when the convertible media type carried in the second call request includes text and audio format, specific information of the second call request may be displayed in text format in the interactive interface, for example, displaying the number, nickname, name, etc. of the calling terminal; meanwhile, the information such as the number, the nickname, the name and the like of the calling terminal can be played in an audio format. In addition, on the called terminal side, after the second call request is displayed in a video and text format, a confirmation control can be displayed in an interactive interface of the called terminal, and after the user clicks the confirmation button, the second call response information is uploaded to the multimedia service communication system; or after the second call request is played in the audio format, an audio data acquisition process can be activated to acquire voice data input by a user; for example, when acknowledgement information such as "acknowledgement", "consent" and the like input by the user is acquired, the second call response information is uploaded to the multimedia service communication system. Or, the option of displaying a plurality of media types in the interactive interface of the called terminal is also possible, and when the user selects a media type, the second call response information is uploaded to the multimedia service communication system. The second call response information may include a called-side media type selected by the user.
After receiving the second call response information uploaded by the called terminal, the multimedia service communication system can convert the second call response information into first call response information in a calling terminal media type format and send the first call response information to the calling terminal, and a media conversion link is constructed between the calling terminal and the called terminal.
Or in some embodiments, when the user refuses the current second call request at the called terminal side, the refusal response information containing the refusal information may also be uploaded to the multimedia service communication system.
In this example embodiment, the method may further include: and receiving and displaying the second media data of the called terminal media type.
Specifically, for the called terminal, after receiving the second media data of the called terminal media type issued by the multimedia service communication system, the second media data can be directly played and displayed on the called terminal.
In this example embodiment, the method may further include: and collecting third media data of the called terminal media type and sending the third media data to the multimedia service system, so that the multimedia service system can convert the third media data into fourth media data of the calling terminal media type and send the fourth media data to the calling terminal.
In particular, for the called terminal, after responding to the first call request of the calling terminal and establishing the media conversion link, third media data of the selected called-side media type can be transmitted to the multimedia service system. For example, the user may send a media stream in text, audio or video format at the called terminal. After receiving the third media data, the multimedia service system can encode the third media data, convert the third media data into fourth media data corresponding to the media type of the calling terminal, send the media stream to the calling terminal, and display and play the media stream at the calling terminal.
In some embodiments, for the calling terminal, an interactive interface may be provided, where the user may initiate the first call request to the called terminal through touch selection, voice input, and so on. For example, the user may input identity information such as the number, name, nickname, etc. of the called terminal in the interactive interface; and determining the media type of the calling terminal. For example, when the user initiates the first call request in text format, the text format may be determined to be the caller-side media type. The first call request is sent to the multimedia service system through the accessed core network, and the multimedia service system processes the first call request to generate a second call request, and the second call request is sent to the called terminal. After receiving the processed first call response information forwarded by the multimedia service system, the media stream data can be sent to the called terminal. At this time, the first call response information can be displayed and played on the calling terminal in the format of the calling terminal media type, so as to prompt the calling terminal side user to input information and perform real-time information interaction with the called terminal.
In some example implementations, referring to fig. 4, step 401. A user initiates a media type 1 based call request at a calling terminal side; step 402, transmitting a call request based on the call request of the media type 1 to a multimedia service communication system through a calling end core network; in the process, the media type 1 selected by the calling terminal is used as a designated format to transmit negotiation signaling; step 403, the multimedia service communication system may determine, according to a preset list of switchable media types, a switchable media type corresponding to the media type 1, for example, media types 2 and 3; completing media negotiation parameter conversion in the call request based on the media types 1, 2 and 3; step 404, step 405, the call request carrying media types 1, 2, 3 is sent to the called terminal through the called terminal core network. Step 406, the called user selects the local media type, such as media type 2, according to the need at the called terminal side; step 407, step 408, the called end core network accessed by the called terminal returns the call response carrying the media 2 to the multimedia service system; step 409, step 410, the multimedia service communication system converts the call response into a call response in a media type 1 format readable by the user at the calling terminal side, and sends the call response to the calling terminal through the calling terminal core network; and completing call establishment and establishing a media conversion link. Step 411, step 412, the calling terminal sends the media stream of the media type 1 to the multimedia service communication system through the calling terminal core network, and then the multimedia service communication system converts the media stream into the media stream of the media type 2 readable by the called terminal side user, thereby realizing the transmission of the media data of both parties by using the multimedia service communication system; the multimedia service communication system completes the identification and conversion of the media information of the media type 1 and the media type 2; each terminal device presents the received media information to the user. If the calling terminal and the called terminal use the same media type, for example, both media type 1, the multimedia service communication system may not perform format conversion on the media stream. When one end actively ends the real-time communication, the network resources of the currently established media conversion link can be recovered.
According to the multimedia data conversion method provided by the embodiment of the disclosure, through a multimedia service communication system deployed in a core network, a call request containing a calling terminal media type initiated by a calling terminal is received, the call request is processed, and a list of the calling terminal media type and the media type capable of being converted with each other is provided for a called terminal side user to select; after receiving call response information generated by the called terminal based on the selected called terminal media type, establishing a media conversion link between the calling terminal and the called terminal; after the media stream of the calling terminal media type sent by the calling terminal is converted into the media stream of the called terminal media type, the converted media stream is sent to the called terminal; similarly, the media stream of the called media type sent by the called terminal can be converted into the media stream of the calling media type and then sent to the calling terminal. The identification and conversion of the media information between the calling terminal and the called terminal are realized; the calling side and the called side can use different media types to conduct real-time information interaction without manual participation.
