For example, the amount of the VLANs 10a and 10b is two. The VLANs 10a and 10b also cooperate with a plurality of wireless communication devices to transmit packets. For example, the amount of the wireless communication devices 12a and 12b is two. The VLANs 10a and 10b are formed by routers connected with a plurality of servers. The wireless access setting device of the present invention comprises at least one wireless access point 14 and a wireless access controller 16 connected with the wireless access point 14 through an unshielded twisted pair (UTP). A manager can log in to a Web page management interface of the wireless access controller 16, so as to set and manage the system. The wireless access point 14 and the wireless access controller 16 can use a network control protocol to communicate with each other. For example, the network control protocol is a smart discovery protocol. The wireless access point 14 broadcasts at least one target identification datum, such as a service set identifier (SSID). For example, the two different target identification data is used in the embodiment. The amount of the wireless access point 14 is one. When the two wireless communication devices 12a and 12b respectively receive the target identification data, the wireless communication devices 12a and 12b transmit their first media access control addresses and the target identification data corresponded thereof to the wireless access point 14 according to the target identification data received and stores them in the wireless access point 14. Using the network control protocol, the wireless access point 14 outputs its second media access control address, the first media access control addresses and the target identification data corresponded thereof. The wireless access controller 16 is connected with the VLANs 10a and 10b and presets pairing data for the two target identification data corresponding to the VLANs 10a and 10b. Using the network control protocol, the wireless access controller 16 automatically receives the second media access control address, the first media access control addresses and the target identification data corresponded thereof, stores them in pairs and uses them and the pairing data to control the wireless communication devices 12a and 12b and the corresponding VLANs 10a and 10b to transmit the packets through the wireless access point 14.

[0021] The wireless access controller 16 further comprises a first power supply 18, a transmission power source unit 20, a first processor 22, a first memory 24 and a packet switch 26, wherein the transmission power source unit 20 complies with a communication protocol of IEEE802.3af or IEEE802.3at. The first power supply 18 receives a first external voltage VE1, converts the first external voltage VE1 into a first direct-current (DC) voltage and outputs the first DC voltage, wherein the first external voltage VE1 is an alternative-current (AC) voltage or a DC voltage. The transmission power source unit 20 is connected with the first power supply 18 and the wireless access point 14 and receives the first DC voltage. The first processor 22 is connected with the transmission power source unit 20, receives the first DC voltage, and uses the first DC voltage to control the transmission power source unit 20 to supply the first DC voltage to the wireless access point 14. The first memory 24 is connected with the first processor 22 and stores the pairing data. The packet switch 26 is connected with the VLANs 10a and 10b, the transmission power source unit 20 and the first processor 22, receives the first DC voltage, uses the first DC voltage and the network control protocol to receive the second media access control address, the first media access control addresses and the target identification data corresponded thereof through the transmission power source unit 20, and uses the first processor 22 to store them in the first memory 24 in pairs. The packet switch 26 and the first processor 22 use the second media access control address, the first media access control addresses, the target identification data corresponded thereof and the pairing data to control the wireless communication devices 12a and 12b and the corresponding the VLANs 10a and 10b to transmit the packets through the transmission power source unit 20 and the wireless access point 14.

[0022] The wireless access point 14 further comprise a wireless transceiver unit 28, a second memory 30 storing the two target identification data, a transmission powered unit 32 and a second processor 34, wherein the wireless transceiver unit 28 complies with a communication protocol of IEEE802.11a, IEEE802.11b, IEEE802.11g, IEEE802.11n or IEEE802.11ac, and wherein the transmission powered unit 32 complies with a communication protocol of IEEE802.3at or IEEE802.3af. The transmission powered unit 32 is connected with the transmission power source unit 20. The second processor 34 is connected with the transmission powered unit 32, the wireless transceiver unit 28 and the second memory 30, receives the first DC voltage through the transmission powered unit 32, uses the wireless transceiver unit 28 to broadcast the target identification data and to receive the first media access control addresses and the target identification data corresponded thereof, and stores the first media access control addresses in the second memory 30. Using the network control protocol, the second processor 34 outputs its the second media access control address, the first media access control addresses and the target identification data corresponded thereof through the transmission powered unit 32. When a user uses an appointed target identification datum to perform connection, the wireless access controller 16 immediately and automatically dumps packets to the VLAN as a destination according to the setting, so as to conveniently manage and distribute the packets, thereby achieving central automation setting, reducing the times of the additional setting and overcoming the problem with difficult management and security for data distribution.

[0023] Refer to FIG. 1 and FIG. 2. The operation process of the present invention is introduced below. The process suits to the state that a new user joins, and that a user roams from a target identification datum to another target identification datum, and that a user roams from a wireless access point to another wireless access point. Firstly, in Step S10, the second processor 34 receives the first DC voltage through the transmission powered unit 32 and uses the wireless transceiver unit 28 to broadcast the two target identification data. Then, in Step S12, when the two wireless communication devices 12a and 12b respectively receive the two target identification data, the wireless communication devices 12a and 12b transmit their first media access control addresses and the target identification data corresponded thereof to the wireless transceiver unit 28 according to the target identification data received, whereby the second processor 34 stores the first media access control addresses in the second memory 30. Then, in Step S14, using the network control protocol, the second processor 34 outputs its the second media access control address, the first media access control addresses and the target identification data corresponded thereof through the transmission powered unit 32. Then, in Step S16, the packet switch 26 receives the first DC voltage, uses the first DC voltage and the network control protocol to receive the second media access control address, the first media access control addresses and the target identification data corresponded thereof through the transmission power source unit 20, and uses the first processor 22 to store them in the first memory 24 in pairs. Finally, in Step S18, the packet switch 26 and the first processor 22 use the second media access control address, the first media access control addresses, the target identification data corresponded thereof and the pairing data to control the wireless communication devices 12a and 12b respectively cooperating with the corresponding the VLANs 10a and 10b to transmit the packets through the wireless transceiver unit 28, the second processor 34, the transmission powered unit 32 and the transmission power source unit 20. As a result, the packets from staffs in a company or clients can be dumped to the corresponding network, such as an internal network of the company or a wireless network for clients.

[0024] The present invention has two kinds of ways of cleaning the first media access address. The first way is introduced below. The wireless access controller 16 regularly transmits check packets to the corresponding wireless access point 14 according to the two target identification data and the network control protocol. The wireless access point 14 uses the check packets to find the first media access control addresses which are stored by itself and which correspond to the two target identification data, and transmits response packets corresponded thereof to the wireless access controller 16 by using the network control protocol. When at least one first media access control address leaves the wireless access point 14 and the wireless access controller 16 uses the response packets to determines the first media access control address stored in the wireless access controller 16 is not stored in the wireless access point 14, the wireless access controller 16 removes the first media access control address which is stored by itself and which is not stored in the wireless access point 14, and its setting for the second media access control address, the target identification datum and the VLAN.

[0025] Specifically, refer to FIG. 1 and FIG. 3. Firstly, in Step S20, the first processor 22 regularly transmits check packets to the corresponding second processor 34 through the transmission powered unit 32 and the transmission power source unit 20 according to the two target identification data and the network control protocol. Then, in Step S22, the second processor 34 uses the check packets to find the first media access control addresses which are stored by the second memory 30 and which correspond to the two target identification data, and transmits response packets corresponded thereof to the first processor 22 through the transmission powered unit 32 and the transmission power source unit 20 by using the network control protocol. Then, in Step S24, the first processor 22 uses the response packets to determine whether the first media access control address stored in the first memory 24 is not stored in the second memory 30. If the answer is yes, the first processor 22 removes the first media access control address which is stored by the first memory 24 and which is not stored in the second memory 30, and its setting for the second media access control address, the target identification datum and the VLAN, as shown in Step S26. If the answer is no, the first processor 22 dose not perform any activities, as shown in Step S28. For example, when the first media access control address of the wireless communication device 12a leaves the second memory 30, the first processor 22 uses the response packets to determine whether the first media access control address of the wireless communication device 12a stored in the first memory 24 is not stored in the second memory 30. As a result, the first processor 22 removes the first media access control address of the wireless communication device 12a which is stored by the first memory 24 and which is not stored in the second memory 30, and its setting for the second media access control address, the target identification datum and the VLAN 10a.

[0026] In addition to the abovementioned way, the second way of cleaning the first media access control address is introduced below. Refer to FIG. 1. The wireless access point 14 actively finds the first media access control addresses which are stored by itself and which correspond to the two target identification data, and regularly transmits leave packets corresponded thereof to the wireless access controller 16 by using the network control protocol. When at least one first media access control address leaves the wireless access point 14 and the wireless access controller 16 uses the leave packets to determines the first media access control address stored in the wireless access controller 16 is not stored in the wireless access point 14, the wireless access controller 16 removes the first media access control address which is stored by itself and which is not stored in the wireless access point 14, and its setting for the second media access control address, the target identification datum and the VLAN.

[0027] Specifically, refer to FIG. 1 and FIG. 4. Firstly, in Step S30, the second processor 34 actively find the first media access control addresses which are stored by the second memory 30 and which correspond to the two target identification data, and transmits leave packets corresponded thereof to the first processor 22 through the transmission powered unit 32 and the transmission power source unit 20 by using the network control protocol. Then, in Step S32, the first processor 22 uses the leave packets to determine whether the first media access control address stored in the first memory 24 is not stored in the second memory 30. If the answer is yes, the first processor 22 removes the first media access control address which is stored by the first memory 24 and which is not stored in the second memory 30, and its setting for the second media access control address, the target identification datum and the VLAN, as shown in Step S34. If the answer is no, the first processor 22 dose not perform any activities, as shown in Step S36. For example, when the first media access control address of the wireless communication device 12b leaves the second memory 30, the first processor 22 uses the leave packets to determine whether the first media access control address of the wireless communication device 12b stored in the first memory 24 is not stored in the second memory 30. As a result, the first processor 22 removes the first media access control address of the wireless communication device 12b which is stored by the first memory 24 and which is not stored in the second memory 30, and its setting for the second media access control address, the target identification datum and the VLAN 10b.

[0028] Refer to FIG. 5. The second embodiment of the wireless access setting device of the present invention is introduced below. The second embodiment is different from in that the first embodiment in an internal circuit of the wireless access point 14 and that the transmission powered unit 32 and the transmission power source unit 20 do not comply with a communication protocol of IEEE 802.3af or IEEE802.3at. In the second embodiment, The wireless access point 14 further comprise a wireless transceiver unit 28, a second memory 30 storing the two target identification data, a transmission powered unit 32, a second power supply 36 and a second processor 34, wherein the wireless transceiver unit 28 complies with a communication protocol of IEEE802.11a, IEEE802.11b, IEEE802.11g, IEEE802.11n or IEEE802.11ac. The transmission powered unit 32 is connected with the transmission power source unit 20 and the second power supply 36. The second power supply 36 receives a second external voltage VE2, converts the second external voltage VE2 into a second DC voltage and outputs the second DC voltage. The second processor 34 is connected with the transmission powered unit 32, the wireless transceiver unit 28 and the second memory 30, receives the second DC voltage through the transmission powered unit 32, uses the wireless transceiver unit 28 to broadcast the two target identification data and to receive the first media access control addresses and the target identification data corresponded thereof, and stores the first media access control addresses in the second memory 30. Using the network control protocol, the second processor 34 outputs its the second media access control address, the first media access control addresses and the target identification data corresponded thereof through the transmission powered unit 32.

[0029] The operation process of the second embodiment of the present invention is similar to that of FIG. 2 of the first embodiment. In Step S10 of FIG. 2, the second processor 34 receives the second DC voltage through the transmission powered unit 32 and uses the wireless transceiver unit 28 to broadcast the two target identification data, and other steps of the second embodiment are identical to those of the first embodiment so will not be reiterated. Besides, in the second embodiment, the processes of using the wireless access controller to transmit check packets and using the wireless access point to transmit leave packets are identical to those of the first embodiment, so the processes will not be reiterated.

[0030] In conclusion, the present invention presets pairing data for target identification datum corresponding to virtual local area networks (VLANs) in a wireless access controller, whereby packets are automatically dumped to the VLAN as a destination according to the setting when a user is in connection, and uses central setting automation to manage the packets to overcome the problem with security for data distribution.

[0031] The embodiments described above are only to exemplify the present invention but not to limit the scope of the present invention. Therefore, any equivalent modification or variation according to the shapes, structures, features, or spirit disclosed by the present invention is to be also included within the scope of the present invention.
