Embodiment Construction

[0048] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0049] The steps shown in the flowcharts of the figures may be performed in a computer system, such as a set of computer-executable instructions. Also, although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0050] At present, there are the following situations in the method for SBC access terminal real-time media stream:

[0051] 1. The port usage on the SBC side is large, and the public network IP address needs more

[0052] refer to figure 2, this method needs to allocate a different port number on the SBC for each terminal, and establish a corresponding mapping relationship by detecting the message sent to the local port. An IP address can only have up to 65535 ports, which means that an IP address can support up to 65535 media ...

Abstract

The invention discloses a real-time media stream access method and device, communication equipment and a terminal. The method comprises the steps that the communication equipment determines a media stream identification corresponding to a real-time media stream in a process of establishing a real-time media stream session; the communication device allocates a home terminal port to the real-time media stream, wherein each home terminal port corresponds to one or more real-time media streams; and after a real-time media stream session is established, the communication equipment forwards a mediamessage carrying the real-time media stream, and the media message carries the media stream identifier. According to the method disclosed in the embodiment of the invention, the media message carriesthe terminal media stream identifier, and a plurality of real-time media streams can share one home terminal port, so that the utilization rate of the media port is improved, the system capacity is improved, and the requirement of super-large-scale terminal access is met.

Description

technical field [0001] This article relates to, but is not limited to, a method, device, communication device, terminal, and computer-readable storage medium for accessing real-time media streams. Background technique [0002] IMS (IP Multimedia Subsystem, Internet Protocol Multimedia Subsystem) is a subsystem that supports IP multimedia services proposed by 3GPP (Third Generation Partnership Project, third generation partnership project). It is the development direction of multimedia communication. As an application subsystem in the 4G era The system can well meet the communication between people in the 4G era. Its notable feature is that it adopts the SIP (Session Initial Protocol, Session Initial Protocol) system, the communication has nothing to do with the access mode, and it has the control of various multimedia services. Separation of function and bearing capacity, separation of call and session, separation of application and service, separation of business and networ...
