Embodiment 1

[0074] In this embodiment, the ROHC compressor at the local end and the ROHC decompressor at the opposite end are ready. After sending a series of initialization messages, there are multiple feedback messages in the feedback message sent by the ROHC decompressor at the opposite end to the ROHC compressor at the local end. When filtering, it is necessary to judge the type of feedback packets one by one, and select different filtering methods for different types. In addition, the latest received feedback message among the plurality of feedback messages is preferentially selected for filtering. Figure 4 is a flow chart of feedback message processing according to Embodiment 1 of the present invention, such as Figure 4 As shown, the process includes (step S401-step S408):

[0075] Step S401, receiving a series of feedback messages, and obtaining the latest received feedback message among the multiple feedback messages as the feedback message to be filtered;

Embodiment 2

[0084] In this embodiment, the ROHC compressor at the local end and the ROHC decompressor at the opposite end are ready. After sending a series of initialization messages, the multiple feedback messages sent by the ROHC decompressor at the opposite end to the ROHC compressor at the local end are only STATIC-NACK Feedback message. In addition, the latest received feedback message among the plurality of feedback messages is preferentially selected for filtering. Figure 5 It is a flow chart of STATIC-NACK feedback message processing according to Embodiment 2 of the present invention, such as Figure 5 As shown, the process includes (step S501-step S507):

[0085] Step S501, receiving a series of STATIC-NACK feedback messages;

[0086] Step S502, obtain the latest STATIC-NACK feedback message in a series of STATIC-NACK feedback messages, determine whether to set the STATIC-NACK feedback flag, if set, perform step S503, otherwise, perform step S504;

Embodiment 3

[0093] In this embodiment, the ROHC compressor at the local end and the ROHC decompressor at the opposite end are ready. After sending a series of initialization messages, the multiple feedback messages sent by the ROHC decompressor at the opposite end to the ROHC compressor at the local end are only NACK feedback messages. arts. In addition, the latest received feedback message among the plurality of feedback messages is preferentially selected for filtering.

[0095] Step S602, obtain the latest NACK feedback message in a series of NACK feedback messages, judge whether to set the NACK feedback flag, if set, then perform step S603, otherwise, perform step S604;

[0096] Step S603, discarding the NACK feedback message;

Abstract

A method and apparatus for processing feedback messages are provided by the present invention, which are used in network devices at both ends transmitting data messages by adopting a Robust Header Compression (ROHC) scheme to process the feedback messages. Wherein, the network device at either end is configured with a compressor and a decompressor. In the method mentioned above, after the compressor of the network device at either end receives a plurality of feedback messages transmitted by the opposite decompressor, a plurality of feedback messages are filtered to filter out redundant feedback messages. The compressor mentioned above processes the plurality of filtered feedback messages. The technical solution provided according to the present invention, solves the problem of low compression processing efficiency resulted from that the compressor processes the redundant feedback messages item by item in the prior art, improves the processing efficiency of the compressor, lightens the burden of the compressor, avoids the loss of high priority service messages, and thus improves the Quality of Service (QoS) of the service.

Description

technical field [0001] The present invention relates to the communication field, in particular to a feedback message processing method and device. Background technique [0002] Robust Header Compression (Robous Header Compression, referred to as ROHC) is a function of this layer implemented inside the protocol layer PDCP (Packet Data Convergence Protocol). Compress headers of data packets transmitted over the air interface, such as IP headers, UDP headers, and RTP headers, and then transmit the compressed data to save air interface bandwidth resources. [0003] The ROHC mechanism mainly compresses the protocol header, and its functional entities include a compressor for compressing the protocol header and a decompressor for restoring the protocol header. [0004] There are corresponding modes and states at the compressor and decompressor side. The ROHC mode can be divided into unidirectional mode and bidirectional mode. The unidirectional mode means that data can only be tr...
