Title:
METHOD FOR OBTAINING NETWORK ADDRESS, ACCESS DEVICE AND COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2009/059508
Kind Code:
A1
Abstract:
A method for obtaining network address is provided, which includes: establishing
a mobile station context when the mobile station accesses network; receiving
an Ethernet message carried by uplink service flow; obtaining a MAC address of
source terminal equipment from the uplink Ethernet message and establishing
the corresponding relation between the MAC address and the corresponding mobile
station context. Another method for obtaining network address is also provided,
which includes: obtaining a destination IP address from a received downlink
message, wherein the destination IP address points to a terminal equipment and
the terminal equipment connects with a mobile station. The corresponding relation
between the destination IP address and the mobile station context that is established
in advance is established. An access device is provided, which includes a storage
unit, an uplink-receiving unit and a learning unit. The above methods can increase
the switching characteristic of two-layer message in the wireless user management
architecture, ensure the downlink message to obtain the required wireless transmission
QoS guarantee and improve the credibility of the TE IP address learned by the access
device.
