Abstract
Disclosed in the present disclosure is a method for realizing wireless network convergence. The method comprises: constructing a convergence link table in an AP of a wireless network cell; arranging a user management system in an external network; when cross-cell movement of a user station occurs, the user management system configuring convergence link tables in corresponding access points (APs) of two cells; and based on the configured convergence link tables, data transmitted by the user station in an original cell being transmitted in a new cell, thereby realizing wireless network convergence.
Claims20
A method for implementing wireless network convergence, comprising:
- constructing a convergence link table in an access point (AP) of a wireless network cell, the convergence link table of the AP including a wireless forwarding table and a transfer-out link table, wherein each entry of the wireless forwarding table records a correspondence between an IP address and a MAC addresses of a user station in the wireless network cell, and each entry of the transfer-out link table records a correspondence between an IP address of a user station before leaving the wireless network cell and global IP address information of a transfer-out target station after the user station leaves the wireless network cell;
- setting up a user management system in an external network, the user management system being connected to the plurality of APs, and each AP having the corresponding convergence link table;
- when a first user station moves from an original cell having an original AP to a new cell having a current AP, obtaining, by the user management system, a name of the first user station, a current IP address of the first user station in the new cell, and a global IP address of the current AP reported by the current AP;
- determining, by the user management system according to the name of the first user station, a global IP address of the original AP and an original IP address of the first user station in the original cell;
- sending, by the user management system to the original AP, a signaling to configure a first entry of the transfer-out link table of the original AP with the original IP address of the first user station in the original cell and current global IP address information of the first user station, wherein the global IP address information of the transfer-out target station in the first entry is configured to be the current IP address of the first user station if the first user station is configured with a global IP in the new cell, and to include both the current IP address of the first user station and the global IP address of the current AP if the first user station is configured with a local IP in the new cell;
- and
- transmitting data that the first user station transmitted in the original cell to the new cell based on the transfer-out link table of the original AP and a wireless forwarding table of the current AP.

A wireless network convergence system, comprising:
- a user management system in an external network configured to manage a plurality of wireless network cells connected to the external network, each wireless network cell having an access point (AP) that connects to one or more user stations in the wireless network cell;
- and
- a plurality of APs each set with a convergence link table, the convergence link table of the AP including a wireless forwarding table and a transfer-out link table, wherein each entry of the wireless forwarding table records a correspondence between an IP address and a MAC addresses of a user station in the wireless network cell, and each entry of the transfer-out link table records a correspondence between an IP address of a user station before leaving the wireless network cell and global IP address information of a transfer-out target station after the user station leaves the wireless network cell, wherein
- a user management system including a user manager that dynamically configures the convergence link table in the AP, including:
- when a first user station moves from an original cell having an original AP to a new cell having a current AP, obtaining a name of the first user station, a current IP address of the first user station in the new cell, and a global IP address of the current AP reported by the current AP;
- determining, according to the name of the first user station, a global IP address of the original AP and an original IP address of the first user station in the original cell;
- and
- sending, to the original AP, the original IP address of the first user station in the original cell and current global IP address information of the first user station to configure a first entry of the transfer-out link table of the original AP, wherein the global IP address information of the transfer-out target station in the first entry is configured to be the current IP address of the first user station if the first user station is configured with a global IP in the new cell, and to include both the current IP address of the first user station and the global IP address of the current AP if the first user station is configured with a local IP in the new cell,
- wherein data that the first user station transmitted in the original cell is transmitted to the new cell based on the transfer-out link table of the original AP and a wireless forwarding table of the current AP.
6 more elements
A first access point (AP) device of a first wireless network cell, comprising:
- a memory that stores a convergence link table configured to provide data transmission link information between an AP in previous cell and user station in new cell when the user station moves across wireless network cells, the convergence link table at least includes a wireless forwarding table and a transfer-out link table, wherein each entry of the wireless forwarding table records a correspondence between an IP address and a MAC addresses of a user station in the wireless network cell, and each entry of the transfer-out link table records a correspondence between an IP address of a user station before leaving the wireless network cell and global IP address information of a transfer-out target station after the user station leaves the wireless network cell;
- wherein the first AP is configured to:
- receive, when a first user station moves from the first cell having the first AP to a new cell having a current AP, from a user management system in an external network, an original IP address of the first user station in the first cell and current global IP address information of the first user station to configure a first entry of the transfer-out link table of the first AP;
- configure, the global IP address information of the transfer-out target station in the first entry to:
- be the current IP address of the first user station if the first user station is configured with a global IP in the new cell, and include both the current IP address of the first user station and the global IP address of the current AP if the first user station is configured with a local IP in the new cell;
- and
- transmit data that the first user station transmitted in the first cell to the new cell based on the transfer-out link table of the first AP.
