Problems solved by technology

[0003] At present, audio code streams and video code streams need to be transmitted through different ports between cross-level calls, and each level of media server needs to allocate ports for multiple streams. Therefore, the more sessions there are, the lower the bandwidth and port occupancy rate. The larger the value, the greater the probability of signaling blockage

Embodiment 1

[0066] Figure 1b It is a flow chart of a port multiplexing control method in Embodiment 1 of the present invention. This embodiment is applicable to the situation of multi-way cross-level calls based on the SIP process. The method can be executed by a port multiplexing control device. The device can be implemented by hardware and / or software, and generally can be integrated in a server that provides cross-level call services, such as a signaling server. Such as Figure 1b As shown, the method includes:

[0067] Step 110, the signaling server receives the first multimedia call request directed to the called party.

[0068] In the process of SIP-based multi-way cross-level call, the signaling server can be used to help the calling party and the called party perform signaling interaction, so as to establish a communication link between the two parties, so that the two parties can transmit multimedia streams. In this embodiment, the signaling server can be any level of signali...

Embodiment 2

[0091] figure 2 It is a flow chart of a port multiplexing control method in Embodiment 2 of the present invention. This embodiment is applicable to the situation of multi-channel cross-level calls based on the SIP process. The method can be executed by a port multiplexing control device. The device can be implemented by hardware and / or software, and generally can be integrated in a server that provides cross-level call services, such as a media server. Such as figure 2 As shown, the method includes:

[0092] Step 210, the media server receives the multimedia call request sent by the signaling server at the same level as itself.

[0093] In this embodiment, the media server is mainly used for port allocation, port management and forwarding of multimedia information for various audio and video streams. For example, the media server may allocate its own port for receiving or sending multimedia information according to a multimedia call request sent by a signaling server at t...

Embodiment 3

[0104] image 3 It is an implementation flowchart of an application scenario adapted by the embodiment of the present invention, and this embodiment can be combined with various optional solutions in the foregoing embodiments. Specifically, refer to image 3 , taking a two-level call as an example, assuming that the two-level servers include the first-level signaling server sipserver1 and the second-level signaling server sipserver2, and the corresponding first-level media server mediaserver1 and second-level media server mediaserver2, the client Client A registers on sipserver1, Client B registers on sipserver2, and sipserver2 registers on sipserver1, Client A requests audio stream and video stream from ClientB, the steps of the two-level call flow are as follows:

[0105] F1: Client A sends a first multimedia call request to sipserver1, and the called party is Client B.

[0106] In this embodiment, the first multimedia call request includes a first non-multiplex port for i...

Abstract

The embodiment of the invention discloses a port multiplexing control method, device, server and storage medium. The method includes: the signaling server receives the first multimedia call request directed to the called party; if it is determined that the called party belongs to other signaling servers, then sending the first multimedia call request including the port reuse identifier to the media server at the same level as itself Two multimedia call requests; receive the multiplex port returned by the media server at the same level as itself for the second multimedia call request, and send the third multimedia port including the multiplex port to its own next-level signaling server call request. The technical scheme of the embodiment of the present invention realizes that when there are multiple cross-level calls, various audio and video code streams between the cross-levels can share one multiplexing port, thereby improving the utilization rate of ports and bandwidth.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular, to a port multiplexing control method, device, server, and storage medium. Background technique [0002] Session Initiation Protocol (Session Initiation Protocol, SIP) is a text-based application layer signaling control protocol for multi-party multimedia communication. It is independent of the underlying transmission protocol and is used to establish, modify and terminate Internet Protocol (Internet Protocol, IP) two-party or multi-party multimedia sessions. [0003] At present, audio code streams and video code streams need to be transmitted through different ports between cross-level calls, and each level of media server needs to allocate ports for multiple streams. Therefore, the more sessions there are, the lower the bandwidth and port occupancy rate. The larger the , the greater the probability of causing signaling blockage. Contents of...
