Embodiment 1

[0060] According to an embodiment of the present invention, a ROHC service flow processing method is provided, the method includes: for the ROHC service flow that needs to be fed back, the network element that implements the ROHC function determines the feedback service flow of the ROHC service flow, for example, from the Select a service flow from the successfully established service flow with the same feedback service flow direction as the feedback service flow of the ROHC service flow, and set the selected service flow (that is, the feedback service flow of the ROHC service flow) as the feedback service flow of the ROHC service flow business flow.

[0061] Among them, the method includes the following two situations:

[0062] Situation 1: The terminal is in the activated state, and there may be multiple successfully established service flows in the uplink and downlink at the same time. After the ROHC service flow is successfully established, if the subsequent establishment...

Embodiment 2

[0065] According to an embodiment of the present invention, a ROHC service flow processing method is also provided. For an ROHC service flow that requires a feedback service flow, the ROHC service flow does not carry feedback service flow information when it is initially established. figure 1 is a flow chart of a ROHC service flow processing method according to an embodiment of the present invention, such as figure 1 As shown, including the following steps S102 to S104:

[0066] Step S102: The network element implementing the ROHC function establishes the ROHC service flow without the feedback service flow.

[0067] Step S104: The network element implementing the ROHC function determines the feedback service flow of the ROHC service flow, and sets the determined feedback service flow as the feedback service flow of the ROHC service flow.

[0068] Wherein, the operation of determining the feedback service flow in step S104 may include the following situations:

[0069] Case 1...

Embodiment 3

[0075] According to an embodiment of the present invention, a ROHC service flow processing method is also provided. When the ROHC service flow is established successfully but the corresponding feedback service flow fails to be established, the following method is adopted: release the successfully established ROHC service flow, and then Create new business flows. The establishment of a new service flow is divided into two situations:

[0076] Case 1: A normal service flow without ROHC characteristics (that is, without ROHC compression characteristics) is established.

[0077] Case 2: continue to establish the ROHC service flow; the continued establishment of the ROHC service flow may use the same or different ROHC parameters as the original ROHC service flow.

[0078] Wherein, the network element implementing the ROHC function includes at least one of the following: a terminal, and an access service network gateway.

[0079] The implementation process of the embodiment of the...

Abstract

The invention discloses a method and a device for processing robust header compression (ROHC) service flow. The method comprises the following steps that: a network element for realizing an ROHC function determines feedback service flow of ROHC service flow; and the network element for realizing the ROHC function sets the determined feedback service flow as the feedback service flow of the ROHC service flow. By the method, the problems of waste space bandwidth or poor and unreliable compression efficiency are solved during process of unsuccessfully building the feedback service flow of the ROHC service flow so as to further realize high compression efficiency, high reliability and space bandwidth saving.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for processing a robust header compression (Robust Header Compression, ROHC for short) service flow. Background technique [0002] ROHC is an efficient compression algorithm that defines the headers of the Internet Protocol (Internet Protocol, referred to as IP) layer and above. This method is defined in detail in documents such as RFC3095 and RFC3759 issued by IETF; It is a decompressor. The compressor compresses the header of the input datagram and transmits it to the decompressor through the ROHC channel. The decompressor restores the compressed header. Among them, the functions of the compressor and the decompressor belong to the ROHC function. [0003] The ROHC parameters of each ROHC channel are defined in the RFC document, and these parameters include an optional parameter, that is, the ROHC feedback channel identifier. If the ROHC parameter of the RO...
