Embodiment 1

[0035] This embodiment provides a working mode switching method of the ROHC layer, which is suitable for the compression end and the decompression end, see figure 1 , the method comprises the following steps (step S102-step S106):

[0036] Step S102, when it is necessary to switch the working mode of the ROHC layer, judge whether context information conversion is required according to the working modes before and after switching;

[0037] For example, if the current working mode is a one-way working mode (U mode) or a two-way optimized working mode (O mode) (it can also be simplified as "U / O mode"), when you want to switch to a two-way reliable working mode (R mode) , it is determined that context information conversion is required; or, if the current working mode is the R-mode bidirectional reliable working mode, when switching to a unidirectional working mode or a bidirectional optimized working mode, it is determined that context information conversion is required.

Embodiment 2

[0072] This embodiment provides a device for switching working modes at the ROHC layer, which can be set on the physical device at the compression end or decompression end, see figure 2 , the device consists of:

[0073] The information conversion judging module 22 is used for judging whether context information conversion is required according to the working modes before and after switching when it is necessary to switch the working mode of the ROHC layer;

[0074] The information setting module 24 is connected with the information conversion judgment module 22, and is used for setting the context information of the switched working mode according to the context information of the current working mode when the judgment result of the information conversion judgment module 22 is yes;

[0075] The mode switching module 26 is connected with the information setting module 24 and is used for initiating the working mode switching.

[0076] Wherein, the information conversion judgin...

Abstract

The invention discloses a working mode switching method and device of a robust header compression protocol (ROHC) layer, wherein the method comprises the following steps: when an ROHC layer requires for working mode switching, whether context information conversion is needed is judged according to the working mode before and after switching; and if so, context information with a switched working mode can be set according to the context information in the current working mode, and working mode switching is initiated. According to the invention, the problem that wastes of learning resources in the working mode switching of the ROHC layer can be solved, and the utilization rate of the system resource can be improved.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a method and device for switching working modes of a Robust Header Compression Protocol (Robust Header Compression Protocol, ROHC) layer. Background technique [0002] ROHC is the abbreviation of Robust Header Compression Scheme, which is a general IP-based compression technology, which can be applied to any standard of 3G (3rd Generation Partnership Project, third generation partnership project), and can also be applied to LTE (Long Term Evolution, long-term evolution) and other technologies mainly work between the base station and the user terminal. ROHC mainly compresses the header of the packet flow. Its functional entity is divided into a compression end and a decompression end. The compression end and the decompression end need to maintain a set of context information respectively. When the compression end is sure that the decompression end has maintained sufficient co...
