Ims (intelligent subsystem) is an IP multimedia subsystem, a new form of multimedia service, which can meet the requirements of more new and diversified multimedia services for end-users. The IMS is considered as a core technology of a next-generation network, and is also an important way to solve the convergence of mobile and fixed networks and introduce differentiated services such as triple convergence of voice, data, and video.

An IMS voice network: the IMS-based public telephone system does not refer to the original circuit-switched network PSTN based on analog technology, but rather to the IMS-based implementation of voice and multimedia communication networks over packet-switched networks.

VoLTE is called Voice over Long-Term Evolution (Long Term Evolution Voice bearer) and refers to a high-speed wireless communication standard facing mobile phones and data terminals. It is based on an IP Multimedia Subsystem (IMS) network, using profiles on LTE that are tailored to the Control plane (Control plane) and Media plane (Media plane) for voice services, which enables voice services (Control and Media plane) to be transported as data streams in an LTE data bearer network without the need to maintain and rely on a traditional circuit switched voice network. The radio access technology of 4G is LTE, and the voice over LTE is called VoLTE.

The 5GNR (New Radio, New air interface) refers to a global 5G standard designed based on a New air interface of OFDM, and is also a very important cellular mobile technology basis for the next generation, and the 5G technology will realize ultra-low delay and high reliability. NR relates to a new wireless standard based on Orthogonal Frequency Division Multiplexing (OFDM). OFDM refers to a [ digital multi-carrier modulation method ]. As 3GPP adopts this standard, the term NR is used to become another substitute for 5G, just as LTE (long term evolution) describes the 4G wireless standard.

VoNR (Voice over New radio): 3GPP has specified that 5G follows the voice architecture of 4G, still providing voice services based on IMS. The radio access technology of 5G is NR, on which the carried voice is called VoNR.

VoLTE and VoNR are respectively one of IMS voice networks, VoLTE being based on 4G and VoNR being based on 5G. In the present invention, all embodiments exemplified by VoLTE-based communication can be directly replaced by the volr-based communication.

In the present invention, at the preparation stage before performing multimedia interaction, a user operates the client 110 to send a connection request and a communication confirmation request to the server 120, so that the client 110 and the server 120 establish connection and simultaneously confirm information such as types of received files, and at this time, the client 110 and the server 120 establish VoLTE communication.

The multimedia menu is an optional menu formed by combining two or more media, namely a man-machine interactive information communication and transmission media, the used media comprise characters, pictures, photos, sounds, animations and films, and interactive functions provided by programs, and the combination of the characters and the pictures is preferably adopted in the invention. The file format of the multimedia menu may be in a format including, but not limited to, asf, wmv, rm, ra, rmvb, MPEG, AVI, DVI, SWF, etc.

The multimedia menu may be in the form of pictures, videos, and the like, and the format is a format commonly used by the client 110 and the server 120, or a format determined after connection and negotiation between the client 110 and the server 120, so that the multimedia menu is suitable for a plurality of different devices. The transmission of the multimedia file can also adopt an RTP protocol for transmission.

FIG. 3 shows a flow diagram of client 110 interacting with server 120.

As shown in fig. 3, after the VoLTE or VoNR communication is established, the server 120 sends a multimedia menu with options to the client 110 in a streaming manner, visually displays the services that can be provided to the user, and the user makes a quick selection according to the indication of the multimedia menu, and the server 120 provides the user with services or further provides a lower-level menu (sub-menu) for the user to select according to the selection made by the user at the client 110 until the user's requirement is met, and the user disconnects the connection at the client 110.

Specifically, taking a mobile phone as the client 110 and a customer service center server as the server 120 as examples:

firstly, a user enables a mobile phone to establish VoLTE or VoNR communication connection with a customer service center server in a mode of dialing a customer service center number through the mobile phone, and after the connection is established, the customer service center server sends a multimedia menu to the mobile phone of the user; after the user's handset receives the multimedia menu,

the user mobile phone interface presents the multimedia menu, and the user performs operations on the multimedia menu interface, including browsing, page turning, clicking, zooming and the like. The user can form a corresponding signal (namely a sub-request) on the mobile phone to be sent to the customer service center server by operating the multimedia menu, for example, clicking or checking an option with the sub-menu, and then the customer service center server identifies the sub-request, sends the corresponding sub-menu according to the sub-request, and repeats the process continuously until the user's requirement is met, and then the user hangs up and cuts off the connection.

In the invention, the multimedia menu is adopted to replace the voice prompt in the prior art, the service content can be visually displayed to the user through the multimedia menu, and the time for listening to the voice prompt is saved.

For example, for the problem that self-service can solve, the user can quickly and accurately find the corresponding service visually, and the user is more inclined to the self-service, instead of directly switching manual service after the call is connected due to the fact that the playing time of the voice prompt is too long, so that a self-service line is idle and the manual service is congested.

The options or buttons on the multimedia menu and the submenus thereof can be set in various ways according to requirements, and the invention is not limited.

When the user operates the multimedia menu or the submenu, any one or a combination of several operations such as clicking, sliding, checking, gesture or clicking a number playing keyboard can be adopted.

According to an embodiment of the present invention, a multimedia menu and a sub-menu are preset at the server 120, including setting the multimedia menu and the sub-menu; partitioning the multimedia menu; setting a dialing keyboard popped up when the multimedia menu is clicked; setting a keyboard dial corresponding to the subarea; associating the keypad dialing with a submenu.

For example, when setting the multimedia menu, when the user clicks the multimedia menu for selecting any content, a dial pad may pop up on the interface of the user client 110, and the user clicks a number of the corresponding content on the dial pad.

When the method is adopted, the signals sent by the user side to the server side 120 are more accurate and stable, and when the two partitions of the multimedia menu are difficult to select through gestures or click modes due to the reasons of short distance or small area, the selection based on the popped-up dial keyboard is more accurate.

Furthermore, the invention can adopt a scheme that two modes of clicking operation on the multimedia menu partition and clicking operation on the dialing keyboard coexist. For example, the user experience can be improved by setting and switching two clicking modes through gestures.

The sub-request is generated when the multimedia menu sent for the first time fails to solve the user problem, and the user operates the multimedia menu to interact with the server 120, for example, the sub-request is generated when the user selects an option in the multimedia bill.

The invention adopts the multimedia menu to replace the voice prompt, realizes the instant arrival of the interactive information and avoids the long-time waiting of the user. Meanwhile, the invention realizes the multimedia interaction between the client 110 and the server 120, does not need additional application programs needed when constructed on the basis of the Internet, and has simple structure and convenient maintenance.

According to an embodiment of the present invention, the fourth step S4 further includes the server 120 switching to manual service according to the sub-request. When the multimedia menu provided by the server 120 cannot meet the user requirement, a corresponding option may be set on the multimedia menu or the sub-menu, and when the user selects the option, the sub-request is sent to switch manual service. At this time, the multimedia interaction is finished and the manual service is started.

Fig. 4 shows a schematic diagram of a multimedia menu.

As shown in fig. 4, the server 120 presets the multimedia menu and the sub-menu, including, step one, setting the multimedia menu and the sub-menu; step two, partitioning the multimedia menu to obtain a gridding partition; setting a corresponding reflection signal during the partition point selection operation; and step four, associating the reflected signal with the submenu. The reflected signal is set by a dual-tone multi-frequency technology.

The request expressed by the reflection signal is a sub-request. The multimedia menu and the series of submenus may be set according to the self-service items provided by the server 120, and simultaneously, the requirement for the client 110 to read quickly needs to be satisfied.

The submenu can be further subdivided, and can be flexibly adjusted according to the service requirement, which is not limited by the invention.

The method shown in fig. 4 may be adopted, first, a multimedia file is made according to the service project, then a transparent picture layer is covered on the multimedia file, the picture layer is divided into a plurality of areas, and each area corresponds to DTMF tones of keys 0 to 9, # and # in a number-playing keyboard, and a multimedia menu can be obtained.

Optionally, in the present invention, the expression of the sub-request may also be selected from other existing or future inventions, and the present invention is not limited thereto.

Through the arrangement, when a user clicks the user end region corresponding to the service item in the multimedia file, the user end can send different sound signals, namely, different DTMF tones can be sent by clicking different regions in the picture layer. The setting of the sub-menu and the multimedia menu can be in the same way, and the invention is not described in detail.

In the invention, the multimedia menu file is set in a partition way and is combined with the DTMF tone of a dial-up keyboard, so that the transmission and the identification of the sub-request generated by the multimedia menu can be completed by utilizing the hardware and the transmission mechanism of the existing voice system, and the multimedia menu transmission system is compatible with the existing IVR interactive voice response system.

According to an embodiment of the present invention, there is provided a method for multimedia interaction in an IMS voice network, including, at a client 110, sending a VoLTE or VoNR communication request, establishing VoLTE or VoNR communication; receiving a multimedia menu; operating the multimedia menu and sending a sub-request; and receiving the multimedia submenu, and repeating the steps until the connection is disconnected.

Compared with voice prompt in the prior art, the mode of the multimedia menu is more intuitive and convenient.

The user returns a further sub-request to the server 120 by operating the multimedia menu at the client 110. The division of the area on the multimedia menu corresponds to a sub-request, which also corresponds to a sub-menu. The sub-request may be in the form of a signal formed by DTMF technology, which is compatible with existing equipment, but the format of the sub-request may also be in other forms.

The client 110 and the server 120 interact with each other through a VoLTE or VoNR communication manner, so that the multimedia menu, the request, the sub-menu, and the like can be transmitted in real time, and the smoothness and the stability of the interaction can be ensured.
