Embodiment Construction

[0030] In the prior art, for the media plane, the mechanism that the Real-time Transport Protocol (RTP) is carried on the User Data Protocol (UDP) is often used, but those skilled in the art know that UDP cannot provide The function of multi-hole, that is, it cannot support multi-path.

[0031] Embodiments of the present invention provide a method, device and system for realizing media plane multipathing. In order to enable those skilled in the art to better understand the solution of the present invention, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings and implementation manners.

[0032] The first embodiment of the method for implementing media plane multipathing in the present invention is introduced below.

[0033] This embodiment can be used in the networking situation of the mobile softswitch. figure 2 It shows the interaction relationship between MGWs in the mobile softswitch. Accordin...

Abstract

The invention discloses a method for realizing media plane multipath, including the following steps: a local terminal transmits a path negotiating request containing local terminal address group to an opposite terminal; the local terminal receives the path negotiating response containing opposite terminal address group sent from the opposite terminal; both the local terminal address group and theopposite terminal address group contain at least one address, and the address group of at least one terminal contains at least two addresses; finally, the local terminal sets up a path according to the addresses of the local terminal address group and the opposite terminal address group. The invention also discloses a device and system for realizing media plane multipath. The invention can realize media plane multipath, thereby meeting the requirements of high reliability of telecommunication service.

Description

technical field [0001] The present invention relates to the technical field of communication networks, in particular to a method, device and system for realizing media plane multipathing. Background technique [0002] During transmission on the signaling plane of a communication network, in order to improve transmission reliability, if a Stream Control Transmission Protocol (SCTP) is used, existing technologies support the SCTP multi-home function. Multi-homing refers to multiple IP addresses. Each end of SCTP can provide multiple IP addresses, and multiple IP addresses at each end share one port. Take two IP addresses at each end as an example, such as figure 1 As shown, one end includes IP1 and IP2, the shared port is PORT1, the other end includes IP3 and IP4, and the shared port is PORT2, so that between the two ends, 4 paths can be provided: IP1-IP3, IP1-IP4, IP2-IP3, IP2-IP4. Moreover, each end can define a main IP address, and the path formed by the main IP address...
