Example Embodiment

[0050] Example 1

[0051] This example provides a robust header compression method for sending UDP checksums, and uses UDP packet streams as UDP packets to illustrate. Figure 5 It is a flowchart of the message sending method of Example 1 according to the embodiment of the present invention, such as Figure 5 As shown, the method includes the following steps (step S501-step S506):

[0052] Step S501, the type of the current message to be compressed is UDP, which matches Profile2;

[0053] Step S502, search the Context list corresponding to Profile2, if the IP version number, upper layer protocol type, source address, destination address, source port number, and destination port number of the current UDP message to be compressed are the same as the static part of a certain context, match To the Context;

[0054] Step S503: It is judged whether the condition of "the UDP checksum of the UDP message to be compressed is not 0, but the UDP checksum in the Context is 0" is established, if it...

Example Embodiment

[0058] Example 2

[0059] This embodiment provides a method for sending a robust header compression UDP checksum, which is illustrated by taking a UDP packet stream as an RTP message. Image 6 It is a flowchart of the message sending method according to Example 2 of the embodiment of the present invention, such as Image 6 As shown, the method includes the following steps (step S601-step S606):

[0060] In step S601, the type of the current message to be compressed is RTP, which matches Profile1.

[0061] Step S602, search the Context list corresponding to Profile1, if the IP version number, upper layer protocol type, source address, destination address, source port number, destination port number and synchronization source identifier of the current RTP message to be compressed are statically related to a certain Context If the part is the same, it matches the Context;

[0062] Step S603: Determine whether the condition of "the UDP checksum of the RTP message to be compressed is not...

Abstract

The invention discloses a message sending method and a device thereof. The method comprises the following steps: according to the type of a current robust header compression message, a context corresponding to the message is determined; and when UDP checksum of the message is judged to be nonzero and UDP checksum of the context corresponding to the message is nonzero, the UDP package type of the message is selected as IR-DYN, and the message which has undergone robust header compression is sent according to the UDP package type. According to the invention, the problem that compression efficiency of a compressor is reduced because that IR package is sent when a static part in a message header to be compressed hasn't changed in a related technology is solved. Furthermore, compression efficiency of the system is raised.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a message sending method and device. Background technique [0002] Robust Header Compression (Robust Header Compression, referred to as ROHC), is a general compression technology based on the Internet Protocol (Internet Protocol, referred to as IP), published in the Internet (Internet) Engineering Task Force (Internet Engineering Task Force) RFC3095, It is defined in detail in standard documents such as RFC4815, and its main function is to compress the header of the datagram that needs to be transmitted over the air interface between the user equipment (User Equipment, referred to as UE) and the base station, for example, the real-time transport protocol (Real -time Transport Protocol, referred to as RTP) / User Datagram Protocol (User Datagram Protocol, referred to as UDP) / IP header, and then transmit compressed data to improve air interface bandwidth utilization. [0003] The ...
