頻寬的裝置100之距離分別約為1〇〇公尺、18〇〇公 尺、2000公尺。無線通訊模組u〇取得站台152、站 台162、站台164之接收訊號強度分別約為-4〇dBm、 -88dBm、·9(ΜΒιη，故最小接收訊號強度約為_9讎爪。 9 201246993 相對接受訊號強度設定為10dBm，由運算模組120將 各接收訊號強度減最小接收訊號強度所得之計算結果 分別為 50dBm、2dBm、OdBm，其中 2dBm、OdBm 小 於lOdBm的相對接受訊號強度，故運算模組120選擇 站台162及站台164設定為第一群組（遠端群組），站 台152設定為第二群組（近端群組）。 接著，分配模組130用以指派第一頻寬給第一群 組的站台162、站台164,以及第二頻寬給第二群組的 站台152。藉此，裝置100依據每一個站台152、162、 164的接收訊號強度計算後，透過與相對接收訊號強

站台162、站台164總共兩個站台，故第一分配單元 132將指派5000Kbps之頻寬給站台162、站台164。 表1 第一頻寬之大小 站台數量 每一站台之頻寬 10 201246993 1〜4 5000Kbps 5〜7 3000Kbps 8〜9 2000Kbps 10〜 1000Kbps 此外，分配模組130可更包含第二分配單元134， 第二分配單元134依據第二群組包含的站台數量，指

Description of the Invention: [Technical Field] The present invention relates to a mechanism for allocating bandwidth, and more particularly to an apparatus and method for allocating bandwidth. [Prior Art] The emergence of various wireless communication products has made the use of wireless networks increasingly popular. Due to the development of network technology, various kinds of behaviors that need to transmit and receive a large amount of data are generated, for example, using streaming media (Streaming Media), watching Internet television (IPTV), using P2P (Peer-To-Peer), FTP (File Transfer Protocol), Bluetooth (Bluetooth), etc., these behaviors must rely on sufficient bandwidth. The conventional wireless network environment is that many stations (Stations) are simultaneously connected to the same wireless base station (Access Point, AP) to share the bandwidth of the wireless base station. Among them, the station can be a variety of wireless communication products, such as mobile phones, personal digital assistants (PDAs), notebook computers, tablets, and the like. Since the distance between each station and the wireless base station is different, the distance between the stations will cause uneven use of the bandwidth. Usually, the near-end station enjoys more bandwidth. If the near-end station transmits a large amount of data, it occupies a large amount of bandwidth. The remote station cannot enjoy the bandwidth, which is inconvenient to use. Therefore, the distance from the wireless base station is different, which causes the bandwidth usage of the remote user to become insufficient. 4 201246993 SUMMARY OF THE INVENTION Accordingly, it is an aspect of the present invention to provide a device for allocating bandwidth to solve the problem of bandwidth allocation.

The computing module is configured to calculate the intensity of each received signal minus the minimum received signal strength, and obtain a plurality of calculation results, and then select the corresponding calculation result from the stations to be less than the relative received signal strength, and set the first group, and from the stations Taichung selects the corresponding calculation result that is greater than the relative acceptance signal strength and sets it to the second group. The distribution module is configured to assign a first bandwidth to the first group and a second bandwidth to the second group. According to an embodiment of the invention, a device for allocating bandwidth further includes a timing module. The timing module is used to set an interval time after assigning the first and first bandwidths. After the interval, the wireless communication module will regain the received signal strength of each connected station and find the minimum of each received signal strength. Receive signal strength. According to another embodiment of the present invention, when the station individually sends a plurality of connected wireless communication modules, according to the connection information, the corresponding station receiving signal strength is obtained.

According to still another embodiment of the present invention, a distribution module includes a second component. The second allocation unit is configured to allocate a size of the second bandwidth according to the number of stations included in the second group, where the first frequency is the same when the number of stations included in the first group is the same as the number of stations included in the second group The width can be greater than the second bandwidth. Another aspect of the present invention is to provide a method of allocating bandwidth to solve the problem of bandwidth allocation. The method for allocating the bandwidth firstly connects a plurality of stations, and obtains a plurality of received signal strengths from the stations, and finds the minimum received signal strength among the received signal strengths, and then 5 different received signal strengths are minimized and received. Signal strength. A plurality of calculation results are obtained, and the relationship between each calculation result and the strength of the received No. 2 is compared. Then, from the stations, the corresponding calculation result is less than the relative received signal strength, and the first bandwidth is assigned to the first group, and the corresponding calculation result is selected from the stations to be greater than the relative received signal strength. Set to the second group and assign the second bandwidth to the second group. According to an embodiment of the invention, a method for allocating a bandwidth further includes setting an interval time after assigning the first and second bandwidths, and re-finding the minimum received signal strength in the received signal strength after the interval time. According to another embodiment of the present invention, a method for allocating a bandwidth further includes: when the station individually sends a plurality of connection information, the connection signal strength of the corresponding station is obtained according to the connection information. 201246993 According to still another embodiment of the present invention, the step of assigning a bandwidth to the first group means assigning a size of the first bandwidth according to the number of stations included in the first group. According to still another embodiment of the present invention, the step of assigning a bandwidth to the second group means assigning a size of the second bandwidth according to the number of stations included in the second group, and if the number of stations included in the first group is the second When the number of stations included in the group is the same, the first bandwidth may be greater than the second bandwidth. In summary, the method and apparatus for allocating bandwidth of the present invention have significant advantages and benefits over the prior art. When the station is connected to the device for allocating the bandwidth, according to the received signal strength of each station, the group is distinguished by comparing with the strength of the received signal, and each of the groups defined in the adaptive (Adaptive) The bandwidth of a station to reach the bandwidth will not be occupied by some stations. The above description and the following embodiments will be described in detail by way of examples, and further explanation of the technical solutions of the present invention will be provided. [Embodiment] In order to make the description of the present invention more complete and complete, reference is made to the accompanying drawings and the accompanying drawings. On the other hand, well-known elements and steps are not described in the embodiments to avoid unnecessarily limiting the invention. Please refer to FIG. 1. FIG. 1 is a block diagram of a device 100 for allocating bandwidth according to an embodiment of the present invention. The bandwidth-distributing device 100 can be applied to a wireless access point, a wireless base station, or various related technical aspects. In use, the device for allocating bandwidth] can be wirelessly connected to the station, thereby allocating bandwidth to the station. The station can be used for various wireless communication products, such as mobile phones, personal digital assistants (PDAs), notebook computers, tablets. Wait. It should be understood that the number of stations of the figure is only or μ __ is not used to limit the invention, and is familiar. ~ Actually, the actual calculation module 12^ of the platform is flexibly defined, and the width of the module 1 includes the wireless communication module 110, and the module is transferred to the module 130. As shown in FIG. 1, the calculation is connected to the computing module 12Q and the line communication module 11G, and the distribution module 130 is individually issued and exemplified according to one of the stages 164 of the present invention. The station 152, the station 162, and the station line The information is divided into two parts: 'Wireless communication module U〇 according to the strength of the serial number; station 172 port 152, station 162, station 164 receiving device (10) / disconnect (four) station from station 174, station 176 allocation allocation bandwidth The bandwidth is given to 'therefore, the device for allocating the bandwidth is just eight wide 172, the station 174, the station 176 〇 152. The nearest one is the station ^: two, the farthest from the device that allocates the bandwidth _. The station is 162 'station 164 wireless communication 槿11Λ m , and U 〇 is used to obtain a plurality of Received Signal Strength Indication (RSSI) from multiple stations 152, station 8 201246993 162, and station 164 respectively, and find A minimum received signal strength in the received signal strength. The received signal strength may be a signal strength indicator for determining the station and the device for allocating the bandwidth. The closer the station is to the device for allocating the bandwidth, the stronger the received signal strength and the weaker the further. The computing module 120 is configured to calculate the received signal strength minus the minimum received signal strength to obtain a plurality of calculation results, and then the station 152, the station 162, and the station 164 select the corresponding calculation result to be less than the relative received signal strength (ie, the station 162). The station 164) is set to the first group 'the first group is the remote group. On the other hand, the computing module 120 selects from the station 152, the station 162, and the station 164 that the corresponding calculation result is greater than the relative received signal strength (ie, the station 152) is set to the second group, and the second group is the near group. group. In an embodiment, the computing module 120 can analyze the received signal strength to determine the specific value of the received signal strength, so the value of the received signal strength can be adjusted according to the actual situation. Alternatively, the specific value of the received signal strength can be set by the system designer. For example, the distance between the station 152, the station 162, the station 164 and the device 100 for distributing the bandwidth is about 1 m, 18 ft, and 2000 metre, respectively. The receiving signal strengths of the wireless communication module u 〇 obtaining station 152, station 162, and station 164 are respectively -4 〇 dBm, -88 dBm, · 9 (ΜΒιη, so the minimum received signal strength is about _9 雠 claw. 9 201246993 relative The received signal strength is set to 10 dBm, and the calculation result of the received signal strength minus the minimum received signal strength by the computing module 120 is 50 dBm, 2 dBm, and OdBm, respectively, wherein 2 dBm and OdBm are less than 10 dBm of the relative received signal strength, so the operation module 120 select station 162 and station 164 are set as the first group (remote group), and station 152 is set as the second group (near end group). Next, the distribution module 130 is used to assign the first bandwidth to the first A group of stations 162, stations 164, and a second bandwidth are given to the stations 152 of the second group. Thereby, the device 100 calculates and transmits the relative signals according to the received signal strength of each of the stations 152, 162, and 164. The strength is compared to distinguish the group to which it belongs, and the bandwidth of each station in each group is defined by Adaptive, so that the bandwidth is not occupied by a certain station. The distribution module 130 may further include a first allocation unit 132, and the first allocation unit 132 may assign a size of the first bandwidth according to the number of stations included in the first group. The value of the first bandwidth may be based on actual usage. For example, the first allocating unit 132 performs the assignment according to the following list 1. The first group includes the station 162 and the station 164 for a total of two stations, so the first allocating unit 132 will assign a bandwidth of 5000 Kbps to the station 162. Table 164. Table 1 The size of the first bandwidth The number of stations The bandwidth of each station 10 201246993 1~4 5000Kbps 5~7 3000Kbps 8~9 2000Kbps 10~1000Kbps In addition, the distribution module 130 can further include the second allocation unit 134, the second allocation unit 134 assigns a size of the second bandwidth according to the number of stations included in the second group, wherein the value of the second bandwidth can be adjusted according to actual usage. For example, the second allocation unit 134 is assigned according to the following list 2. The second group includes one station of the station 152, so the station 152 will be assigned a bandwidth of 3000 Kbps. Table 2 The size of the second bandwidth The number of stations per station The bandwidth is 1~4 3000Kbps 5~7 2000Kbps 8~9 1000Kbps 10~500Kbps In addition, when the number of stations included in the first group is the same as the number of stations included in the second group, the first frequency assigned by the distribution module 130 The width may be greater than the second bandwidth. For example, according to Table 1 and Table 2 above, if the number of stations in both groups is five, the first bandwidth will be 201246993 3000K: bps' second bandwidth is 2 〇〇〇Kbps. This arrangement is because the received signal strength of the first group is weaker than that of the second group, which may cause an error in the information f, and the data must be transmitted again. To solve such a problem, the first bandwidth is greater than the second frequency. width. In an embodiment of the invention, the device 1 that allocates bandwidth may also include a timing module 140. The timing module 140 is coupled to the distribution module 13A and the wireless communication module 110. After the distribution module 13 assigns the first and second bandwidths to the first group and the second group, the timing module 14 sets an interval time. After the interval time, the wireless communication module 11 will find out The minimum received signal strength in the received signal strength. Among them, the interval can be selected and adjusted according to the needs. The timing module 14 is set because there may be a situation in which the station moves the position within the interval time. Therefore, the bandwidth must be reassigned for the change of status. In practice, the specific implementation manner of the wireless communication module 11〇, the computing module 120, the distribution module 13〇, and the timing module 14〇 may be a software program or a hardware circuit, and those skilled in the art should consider It is necessary to flexibly select the implementation method, and it is not necessary to use all of the software as the hardware circuit, and the part is a software program or a part of the hardware. Figure 2 is a flow chart showing a method of allocating bandwidth according to the present invention. The method 200 of allocating bandwidth can be applied to devices that allocate bandwidth (e.g., wireless access points, wireless base stations), or widely used in related technical aspects. It should be understood that the steps mentioned in this embodiment can be adjusted according to actual needs, except that the order is specifically described. 12 201246993 can even be executed simultaneously or partially. Further, the hardware device 'for the implementation of the method 2 〇 0 has been specifically disclosed as the previous embodiment, and therefore the description thereof will not be repeated. As shown in Fig. 2, in step 21, a plurality of stations are connected. In step 220, the plurality of received signal strengths are respectively obtained from the station, and the minimum received signal strength in the received signal strength is found. In step 240, the received signal strength is reduced by the minimum received signal strength, and the plurality of calculation results are compared, and the relationship between the calculated result and the relative received signal strength is calculated. 'If the calculation result is less than the relative received signal strength, the step is greater than the calculation result. Step 250 is performed relative to the received signal strength. In step 240, the station selects the group whose deer calculation result is less than the relative acceptance signal strength as the group;;,: sends the first-bandwidth to the first group. In step 25, the self-station selection is performed, and the corresponding calculation result is greater than the relative received signal strength, and the second bandwidth is assigned to the second group. The signal strength of each station in the first group is relatively small, and the station in the second group has a relatively large signal strength, so the first group is a remote group, and the first group is a near group. .

J = Frequency also has other stations issuing several disconnection messages, then the root is disconnected 1, and not The bandwidth must be allocated to the corresponding station. In step 240, the number of stations included in the first bandwidth group is assigned, and the number of stations is assigned to be the largest: and the value of the first-bandwidth can be determined in step 250 according to the actual number. The second bandwidth is given to the number of stations included in the first group, and the second bandwidth is assigned a large T. The value of the second bandwidth can be made according to the actual use situation. In addition, in step 240 and step 250, if the number of stations included in the second group is the same, the bandwidth is greater than the first bandwidth. Such an arrangement is because the strength of the received signal is weaker than that of the second group, which can cause information transmission: misconnection is to solve such a problem, so the first bandwidth is assigned to be larger than the second bandwidth. In the present invention, the method 200 can further include steps. In the step, after setting the second bandwidth (step 240, step 250), an interval time is set, and after the interval time, step 22 is performed again to find the minimum received signal strength in the received signal strength. The interval can be selected and adjusted according to requirements. For example, if the interval is set to 4 hours, step 220 will be re-executed every 4 hours. In an embodiment, the method 2 of allocating the bandwidth is implemented as a computer program, and the initial received signal is used to read the relative received signal strength, interval time, first bandwidth, second bandwidth, etc. before execution. After the reading is completed, step 210 is performed. In summary, the application of the present invention has the following advantages. 1. According to the received signal strength of each station, by comparing with the relative received signal strength, to distinguish the group, and 201246993 * and adaptively define the bandwidth of each station in each group, to achieve The bandwidth will not be occupied by some stations. 2. Set the interval time so that if there is a station move, the bandwidth can be automatically re-adjusted after a period of time. While the invention has been described above by way of example, it is not intended to limit the invention, and the invention may be modified and modified in various ways without departing from the spirit and scope of the invention. The scope is subject to the definition of the scope of the patent application attached.
