An: similar to a base station in a traditional network, the network access function is provided for authorized users in a specific area by being deployed at a position close to the UE, and transmission tunnels with different qualities can be determined according to the level of the users, the service requirements and the like to transmit user data. The AN can manage its own resources, make reasonable use of, provide access services for the UE as needed, and is responsible for forwarding control signals and user data between the UE and the core network.

The access network may be an access network employing different access technologies. There are two types of current radio access technologies: third generation partnership project (3rd Generation Partnership Project,3GPP) access technologies (e.g., wireless access technologies employed in 3G, 4G, or 5G systems) and non-third generation partnership project (non-3 GPP) access technologies. The 3GPP access technology refers to an access technology conforming to the 3GPP standard specification, and an access network employing the 3GPP access technology is referred to as a radio access network (radio access network, RAN), wherein an access network device in the 5G system is referred to as a next generation base station node (next generation Node Base station, gNB). The non-3GPP access technology refers to an access technology that does not conform to the 3GPP standard specification, for example, an air interface technology typified by an Access Point (AP) in wifi.

An access network implementing an access network function based on a wired communication technology may be referred to as a wired access network.

An access network implementing access network functions based on wireless communication technology may be referred to as a radio access network (radio access network, RAN). The radio access network can manage radio resources, provide access service for the terminal, and further complete the forwarding of control signals and user data between the terminal and the core network.

The radio access network device may be, for example, a base station (NodeB), an evolved NodeB (eNB or eNodeB), a base station (gNB) in a 5G mobile communication system, a base station in a future mobile communication system, an AP in a WiFi system, or the like, or may be a radio controller in a cloud radio access network (cloud radio access network, CRAN) scenario, or the access network device may be a relay station, an access point, a vehicle-mounted device, a wearable device, and a network device in a future 5G network or a network device in a future evolved PLMN network, or the like.

Cn: and the system is responsible for maintaining subscription data of the mobile network, managing network elements of the mobile network, and providing session management, mobility management, policy management, security authentication and other functions for the UE. Providing network access authentication for the UE when the UE is attached; when the UE has a service request, network resources are allocated to the UE; updating network resources for the UE when the UE moves; providing a fast recovery mechanism for the UE when the UE is idle; releasing network resources for the UE when the UE is detached; when the UE has service data, a data routing function is provided for the UE, such as forwarding uplink data to DN; or receiving the downlink data of the UE from the DN and forwarding the downlink data to the AN so as to send the downlink data to the UE.

DN: is a data network for providing business services for users, and generally, a client is located in a UE, and a server is located in the data network. The data network may be a private network, such as a local area network, or an external network not under the control of an operator, such as the Internet, or a proprietary network co-deployed by an operator, such as a network providing IP multimedia subsystem (IP multimedia subsystem, IMS) services.

Through the architecture of fig. 1, in addition to the basic voice-video call, new call data of the real-time interactive operation media can be transmitted, so that an efficient and practical new call mode is provided for users, and the upgrading of the real-time voice-video call to the enhanced call is realized.

The manner in which the new call (enhanced call) is made may include multimedia presentation, visual interactive menus, screen sharing, etc.

Multimedia to display: one or more of the content may be preset for the call topic, pre-call pictures/videos, etc. When the called terminal rings, the called terminal also receives preset display content and displays the content on the incoming call interface. The preset mode of the content can be various, for example, the content can be preset by manual selection; the user may also select via the communication service platform rules.

For the enterprise user of the enterprise, the business card information displayed by the called terminal needs to be authenticated by the communication operator.

Visual interactive menu: when a user dials a customer service call, it is often necessary to listen to a voice for a longer period of time to be able to determine the desired service. In this case, through the visual interactive menu, the user can quickly browse the menu options and click the screen to select the corresponding menu to enter the required service, thereby improving the service efficiency.

Screen sharing: the two parties in the call can initiate screen sharing, and the screen of the initiating terminal can be presented on the screen of the receiving terminal through the screen sharing.

Content sharing: in the audio and video conversation process, the two parties of conversation can wind information such as text, pictures, videos, positions and the like to the other party, can assist the two parties of conversation, and realizes the transmission of more layers of information.

Media data of the enhanced call beyond the audio and video can be transmitted through the data channel. A Data Channel (DC) for transmitting real-time interactive media outside of the underlying voice-video call is defined in R16 of 3GPP specification 26114 by a session initiation protocol (session initiation protocol, SIP)/session description protocol (session description protocol, SDP), and a user packet protocol (user datagram protocol, UDP)/packet transport layer security protocol (datagram transport layer security, DTLS)/stream control transmission protocol (streamcontrol transmission protocol, SCTP) is established. The data channel and the voice channel exist simultaneously in the call. The data channels can be divided into boot channels (bootstrap data channel, BDC) and application channels (application data channel, ADC). The boot channel is used between the terminal and the server to request and download applications such as hypertext (hypertext markup language, HTML) pages, including javascript, images and style sheets. After the terminal obtains the application program from the guide channel, the application channel can provide a channel used by the application program.
