Abstract

The invention discloses a data channel establishing method and a system; wherein, the method includes that a serving service flow authorization entity receives the resource reservation request message from an anchoring service flow authorization entity; the serving service flow authorization entity sends a successful resource reservation response message to the anchoring service flow authorization entity under the situation that the resource reservation request is admitted; the serving service flow authorization entity receives the resource reservation confirm message from the anchoring service flow authorization entity and sends a channel establishment confirm message to a service flow management entity according to the result of the resource reservation confirm message. The data channel establishing method and the system can enable the number of the channels established by the BS and the AGW to be consistent.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and system for establishing a data channel. Background technique [0002] WiMAX (World Interoperability for Microwave Access, Microwave Access Global Interoperability) is a wireless metropolitan area network technology based on the IEEE802.16 standard. figure 1 is a schematic diagram of the WiMAX network reference model. Among them, CSN (Connectivity Service Network, connection service network), MS / SS (Mobile Station / Subscriber Station, mobile station / subscriber station), ASN (Access Service Network, access service network) are related to access services in the WiMAX network system functional entities. The ASNs are connected through R4 ports. [0003] The specific structure inside the ASN is as follows figure 2 shown. Among them, the AGW (ASN GateWay, ASN convergence gateway) and the BS (Base Station, base station) are connected through the internal interface R6, ...
