Embodiment Construction

[0032] The core idea of ​​the present invention is: when using the IP protocol to transmit voice in the wireless network, first determine the voice packets belonging to the same voice channel; then send the voice packets of the same voice channel to the same port, and transmit them through the same path .

[0033] In order to have a further understanding of the present invention, the method described in the present invention will be described in detail below in conjunction with the accompanying drawings.

[0034] The specific implementation of the method of the present invention is as follows image 3 shown, including the following steps:

[0035] Step 31: In the case of IP transmission in the wireless network, assign a session identifier to the session during session establishment.

[0036] The session identifier can be represented by a datagram protocol UDP port number or a GRE (Generic Routing Encapsulation Protocol) key value or in other ways.

[0037] According to the ...

Abstract

The invention relates to a method for transmitting voice pack in wireless network, which comprises: when the wireless network uses IP protocol to transmit voice pack, the distributor sends the voice pack of same path to the same physical port, via same chain circuit. With inventive method and device, the problem of disorder voice pack in IP transmission can be solved, to improve the voice quality.

Description

Technical field [0001] The present invention involves the field of wireless network communication technology, especially the method and device of phonetic packet transmission in a wireless network. Background technique [0002] In modern communication networks, the user -faced protocol stack used on the IP protocol transmission on the IP transmission interface board is like figure 1 Show.In order to ensure the reliability of IP transmission, various backup measures are often used.For example, if there are multiple ports, the load sharing is often used to achieve multi -port sharing. In this case, if the voice transmission is transmitted in the wireless network, it may cause a messy order.It will lead to poor voice quality. [0003] For example, when voice transmission is performed in the wireless network, it usually shares the load in the units of voice packs, that is, the various voice packages of the same way are sent from different ports.like figure 2 It shows that the voice p...
