A METHOD, SYSTEM AND DEVICE FOR ESTABLISHING DATA PATH IN WIRELESS NETWORK

摘要

The present invention provides a method, system and device for establishing data path in wireless network. Said method includes: judging whether there has a directly accessible route between the source node and destination node; if there has, sending data path DP establishing request message, said DP establishing request message including directly accessible route indication and DP endpoint identifier, said DP endpoint identifier being said source node identifier; receiving DP establishing response message, DP endpoint identifier in said DP establishing response message being destination node identifier, said DP establishing response messageincluding directly accessible route indication. The technical solution of the present invention greatly decreases the burden of the serving gateway.
