Problems solved by technology

[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, including:

[0111] Step 101: Establish a tunnel-based layer two communication path between the data bearer point of the base station BS and the transfer station RS data bearer point 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 two communication path (Path) is established. The tunnel can be used by specific tunneling protocols such as GRE achieve. There are three cases for the granularity selection of the tunnel between the anchor BS and RS, as shown in Figure 3:

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

[0114] ·Based on MSS / SS anchor point BS and RS tunnel

[0115] ·Establish a tunnel between anchor BS and RS based on RS

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 present invention relates to the field of communication, and in particular to a method for flow management based on a tunnel and a wireless access transit system. Background technique [0002] IEEE 802.16 is a broadband wireless access standard, which mainly has two versions: the 802.16 standard broadband fixed wireless access version "802.16-2004", and the 802.16 standard broadband mobile wireless access version "802.16e". The 802.16 protocol is based on the layered model shown in Figure 1, which defines the physical layer (PHY) and data link layer (MAC) of 802.16. The data link layer is divided into service-oriented service specific convergence sublayer (SSCS). Or abbreviated as CS), MAC common part sublayer (MAC CPS) and encryption sublayer (SS). [0003] The following functions are mainly completed in the SSCS sublayer: [0004] ·Receive protocol data packets (PDU packets) from the higher-level protocol layer; [0005] ·Classify high-level PDU packe...
