Detailed Description
The invention will be further illustrated with reference to specific embodiments. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Further, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teaching of the present invention, and such equivalents may fall within the scope of the present invention as defined in the appended claims.
Referring to fig. 1 and 2, the present invention discloses a method for distinguishing played sound in video early media. As shown in the figure, a preferred embodiment thereof specifies the audio played by the video early media 300 as local audio 201 (local ring tone of the called intelligent mobile terminal 200) or carried audio 301 (sound contained in the video early media) when the service application server 100 sends the video early media 300 to the intelligent mobile terminal 200 when the video business card or color ringing service is involved in the IMS mobile communication network environment. Before the service application server 100 sends the video early media 300, it negotiates the format of the video early media 300 with the intelligent mobile terminal 200 by using a media negotiation mechanism, and negotiates and determines how to play the sound of the video early media 300. In the process of media negotiation, the service application server 100 adds configuration information for specifying the audio corresponding to the video early media 300 in a message of the media negotiation, and sends the configuration information to the intelligent mobile terminal 200. The intelligent mobile terminal 200 reads, identifies and stores the configuration information in the media negotiation packet, thereby completing the media negotiation mechanism. After the media negotiation is completed, the service application server 100 sends the video early media 300 according to the negotiated format, and after the intelligent mobile terminal 200 receives the video early media 300, the local audio 201 or the carried audio 301 is played according to the configuration information.
The specific steps of a preferred embodiment of the present invention are:
step S101, after the video card or the color vibration service is triggered, the call signaling reaches the service application server 100.
The application server 100 enters the process of sending the video early media 300 at this time, and performs media negotiation with the intelligent mobile terminal 200 before actually sending the video early media 300.
In step S102, the service application server 100 specifies the audio in the video early media 300 in the media negotiation according to the service type or the service setting.
When determining the audio by the service category, the specific method is as follows: when the service type is a video business card, the audio is designated as the local audio 201 of the intelligent mobile terminal in the configuration information. When the service type is other service (such as a ticker service), the audio is specified in the configuration information as the carried audio 301 of the video early media 300.
When the audio is determined by the service setting, the specific mode is as follows: when the service is an active setting service, the audio is designated as the carried audio 301 of the video early media 300 in the configuration information. When the service is a passive setup service, the audio is designated in the configuration information as the local audio 201 of the intelligent mobile terminal 200. The active setting service comprises the prior service setting according to the calling number, and can also comprise the prior service setting according to the called number, and the like.
Step S103, the service application server 100 adds a new field or a new parameter in the message of the media negotiation mechanism, which is used for carrying configuration information and indicating the audio of the video early media 300.
The message carrying the configuration information is an SIP protocol message or an SDP protocol message.
Taking the SIP protocol packet as an example, the new field may be specifically added to the SIP Invite packet, the SIP 180 packet, or the SIP 183 packet, and the new field is used to transmit the configuration information. For example, an EarlyMedia-Audio field is newly added.
The new parameter may also be added to a Call-Info field or an Alert-Info field in an existing SIP Invite message, SIP 180 message, or SIP 183 message, and the new parameter is used to transmit configuration information. audio = local indicates a local ring tone of the sound playing terminal, and audio = withmediaia indicates a sound playing early media sound part.
Step S104, the intelligent mobile terminal 200 receives the negotiation packet, extracts the configuration information negotiated by the video early media 300, and stores the configuration information.
In step S105, the intelligent mobile terminal 200 continues to perform subsequent negotiation with the service application server 100 to complete the negotiation step of the video early media 300.
Step S106, after the media negotiation is completed, the service application server 100 pushes the video early media 300 to the intelligent mobile terminal 200. According to the configuration information stored before, the intelligent mobile terminal 200 plays the video part of the video early media 300 and simultaneously plays the carried audio 301 or the local audio 201.
The above description is only a preferred embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
