Problems solved by technology

As a result, when media packets are forwarded in the network, the calling party needs to transmit them to the called party through paths such as 5G base stations, tunnels, user plane gateways, IMS servers, user plane gateways, and 5G base stations, resulting in high media packet transmission delays. And the transmission efficiency is low

Embodiment 1

[0026] see figure 2 , figure 2 It is a schematic flowchart of a method for processing a VONR service based on tunnel direct transmission disclosed by an embodiment of the present invention. Wherein, the VONR service processing method based on tunnel direct transmission can be applied to a VONR service system, and the system includes a calling terminal, a called terminal and an IP multimedia server. The embodiment of the present invention does not limit the application system of the VONR service processing method based on tunnel direct transmission. Such as figure 2 As shown, the VONR service processing method based on tunnel direct transmission may include the following operations:

[0027] In order to facilitate the understanding of the overall embodiment content, as image 3 The illustrated VONR service system is taken as an example for illustration. In this embodiment, both the calling end user UE-1 and the called end user UE-2 are 5G users, and can support the VONR ca...

Embodiment 2

[0047] see Figure 5 , Figure 5 It is a schematic diagram of a VONR service processing system based on tunnel direct transmission disclosed by an embodiment of the present invention. Such as Figure 5 As shown, the VONR service processing system based on tunnel direct transmission includes:

[0048] The session building module 1 is used to create a default session between the calling terminal and the called terminal through the IP multimedia server. Connect the calling end, that is, UE-1, to 5GC, and use the DNN (DataNetwork Name, data network name) of the IP multimedia server to create a default PDU (Protocol Data Unit, protocol data unit) session, so that the media plane resources of the calling end Stay at UPF-1.

[0049] Connect the called terminal, namely UE-2, to 5GC, use the DNN (DataNetwork Name, data network name) of the IP multimedia server to create a default PDU (Protocol Data Unit, protocol data unit) session, so that the media plane resources of the called t...

Embodiment 3

[0066] see Image 6 , Image 6 It is a schematic structural diagram of a VONR service processing device based on tunnel direct transmission disclosed in an embodiment of the present invention. in, Image 6 The described VONR service processing device based on tunnel direct transmission can be applied in a VONR service processing system, and the embodiment of the present invention does not limit the application system of the tunnel direct transmission based VONR service processing system. Such as Image 6 As shown, the device may include:

[0067] A memory 601 storing executable program codes;

[0068] a processor 602 coupled to the memory 601;

[0069] The processor 602 invokes the executable program code stored in the memory 601 to execute the method for processing a VONR service based on tunnel direct transmission described in Embodiment 1.

Abstract

The invention discloses a VONR service processing method based on tunnel direct transmission. The method includes: creating a default session for the calling end and the called end through an IP multimedia server; The IP multimedia server registers based on the session initiation protocol; in response to the VONR call instruction sent by the calling end, the IP multimedia server will perform media negotiation between the calling end and the called end registered according to the session initiation protocol to generate a media tunnel, wherein the media tunnel It is used to directly associate the calling terminal with the called terminal; in response to the response instruction corresponding to the VONR call instruction issued by the called terminal, the media message contained in the response instruction is obtained, and the body message is passed through the media tunnel Perform direct transmission to implement VONR service processing. The invention also discloses a VONR service processing system based on tunnel direct transmission. According to the method and system disclosed in the invention, the forwarding efficiency of media messages can be improved and the transmission time delay can be reduced.

Description

technical field [0001] The present invention relates to the technical field of 5G communication, in particular to a VONR service processing method and system based on tunnel direct transmission. Background technique [0002] For 5G NR (5G NR is a global 5G standard based on OFDM-based brand-new air interface design, which is also a very important foundation for the next generation of cellular mobile technology) voice solution design, it continues the 4G LTE (Long Term Evolution) way of carrying voice services through IP networks, The voice service is carried through the wireless network and core network of the 5G network and IMS (IP Multimedia Subsystem, IP Multimedia System). This method is called VONR (Voice Over New Radio, voice over new air interface). Contents of the invention [0003] The 5G NR voice solution based on the IMS network is a voice solution from the calling end to the called end through the IMS service under all IP conditions. That is, by deploying IMS,...
