Embodiment 1

[0107] In this embodiment, in the VOLTE user plane protocol stack, on the core network side, voice data forms voice packets through different frames, frequencies, sampling and encoding rates, and then encapsulates them as RTP (Real-Time Transport Protocol, real-time transport protocol ) data packets, and finally compose IP packets to form VOIP, transmit to the wireless access network side, carry RTP voice payload on PDCP for transmission, and adopt ROHC for enhanced transmission, corresponding to QCI=1 voice bearer. Before establishing the bearer with QCI=1, it is necessary to establish the bearer with QCI=5 for carrying SIP signaling.

[0108] The basic principle of the RFC3095 protocol in the ROHC protocol is to classify the packet header fields, because adjacent packets have many unchanged parts during the transmission of the entire data stream, such as IP addresses and UDP port numbers, some packet header fields Regular changes, such as SN (Sequence Number, serial number) ...

Embodiment 2

[0159] An IR message transmission method is provided in this embodiment, such as figure 2 shown, including the following steps:

[0160] Step 201: When receiving an IR message that does not carry static domain information sent by the first communication device, based on the received historical IR message, obtain the static domain information corresponding to the IR message, and the static domain information Including any one or more combinations of the source IP address, destination IP address, source UDP port number, and destination UDP port number corresponding to the IR message;

[0161] Step 201: Restoring the context information of the IR message based on the static domain information corresponding to the IR message.

[0162] Specifically, in this embodiment, the first preset state and the second preset state are pre-stored in the first communication device, and for different preset states, there are correspondingly different judgments whether the second communication d...

Embodiment 3

[0205] A communication device is provided in this embodiment, such as image 3 As shown, the communication equipment includes:

[0206] A judging module 301, configured to determine whether the second communication device receiving the IR message can obtain static domain information corresponding to the IR message based on the received historical IR message when it is determined that the IR message needs to be sent, The static domain information includes any one or more combinations of the source IP address, destination IP address, source UDP port number, and destination UDP port number corresponding to the IR message;

[0207] A sending module 302, configured to send an IR that does not carry the static domain information if the judging module indicates that the second communication device can obtain static domain information corresponding to the IR message based on the received historical IR message The message is sent to the second communication device, so that the second ...

Abstract

The present invention discloses an IR message transmission method and a communication device. The method includes: determining, when it is determined that an IR message is required to be sent, whethera second communication device receiving the IR message can acquire the static domain information corresponding to the IR message based on a received historical IR message, wherein the static domain information includes any one or more of a source IP address, a destination IP address, a source UDP port number, and a destination UDP port number corresponding to the IR message; if so, sending an IRmessage not carrying the static domain information to the second communication device, so that the second communication device acquires the IR message corresponding to the static domain information based on the received historical IR message in order to restore the context information of the IR message. The method in the present invention can solve the technical problem that an IR message transmission method in the prior art causes the inconsistency of the context information of the ROHC between a compression side and a decompression side and thus causes packet losses.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to an IR message transmission method and communication equipment. Background technique [0002] In the LTE mobile communication network, VOLTE (Voice Over LTE, voice service based on LTE) is an end-to-end voice solution under all-IP conditions. The voice data packets arrive periodically and the packet size is relatively fixed. The voice uses AMR ( Adaptive Multi-Rate, adaptive multi-rate) compression encoding, and then encapsulated into IP packets for transmission. For example: the broadband voice data packet with the highest rate of 23.85Kbps is 61 bytes, but the packet header RTP / UDP / IPv6 reaches 60 bytes, the voice silence packet size is only 7 bytes, but the packet header reaches 60 bytes Festival, bandwidth utilization as low as 10%. ROHC (Robust Header Compression, robust header compression, protocol RFC3095) can compress the message header to 1 to 3 bytes, and the ban...
