Abstract
Disclosed in the present disclosure is a method for realizing continued transmission of user data when a user station crosses multiple wireless network cells. The method includes: constructing a continuation guide table in an access point (AP) of a wireless network cell; when a user station crosses a first cell to a second cell, configuring the continuation guide tables in the AP of the first cell and the AP of the second cell; based on the continuation guide tables, building a data link of a network layer between an correspondent station of the user station and the user station located in a terminal cell; continuously transmitting data between the correspondent station of the user station and the user station in a source cell along the data link after the user station accesses the terminal cell. Further disclosed in the present disclosure is an access point device of a wireless network cell. According to the present disclosure, uninterrupted transmission of data streams can be realized for data being transmitted during a complex condition that a user station crosses a plurality of wireless network cells, thereby improving the user experience when a user surfs the internet using a …
