[0020] In order to expand the coverage of BS, the 802.16 Multihop Relay SG (802.16 Multihop Relay Research Group) has proposed the concept of WiMAX (Global Interconnection of Microwave Access) Relay Station (RS), but so far no RS has been proposed to support services based on tunnels. The method of flow management, and the corresponding RS functional architecture

[0110] For the method described in the present invention, the present invention provides a second embodiment, comprising:

[0111] Step 101: Establish a tunnel-based Layer 2 communication path between the data bearing point of the base station BS and the data bearing point of the relay station RS to which the mobile subscriber station / subscriber station MSS / SS belongs.

[0112] Between the Anchor BS (anchor BS) data bearing point (Data Path Fucnction) and the RS data bearing point to which the MSS / SS belongs, a tunnel-based Layer 2 communication path (Path) is established. The tunnel can be implemented by specific tunneling protocols such as GRE. accomplish. There are three situations for the granularity selection of the tunnel between the anchor BS and RS, such as image 3 Shown:

[0113] Establish a tunnel between anchor BS and RS based on service flow

Abstract

This invention relates to a method for carrying out flow management based on tunnel and a radio access transfer system including: setting up layer communication path based on the tunnel between the data loading points of BS and those of RS belonging to MSS / SS, when BS determines that the received flow message needs the RS transfer and adds control information to it, it carries out tunnel package process and sends out the processed flow messages via said communication path, when said flow message arrives at the RS, which de-packages it and picks up said control information then to transmit it according to said control information.

Description

technical field [0001] The invention relates to the communication field, in particular to a tunnel-based flow management method and a wireless access transfer system. Background technique [0002] IEEE 802.16 is a broadband wireless access standard, and it mainly has two versions: the broadband fixed wireless access version "802.16-2004" of the 802.16 standard, and the broadband mobile wireless access version "802.16e" of the 802.16 standard. The 802.16 protocol is based on the figure 1 The layered model shown, which defines the 802.16 physical layer (PHY) and data link layer (MAC), where the data link layer is divided into business-oriented service-specific convergence sublayer (SSCS or CS for short), MAC Common Part Sublayer (MAC CPS) and Encryption Sublayer (SS). [0003] The SSCS sublayer mainly completes the following functions: [0004] Receive protocol data packets (PDU packets) from a higher protocol layer; [0005] Classify high-level PDU packets; [0006] Payl...
