Description

TECHNICAL FIELD The present invention relates to the field of communications, and in particular to a data processing apparatus and method for a wireless access point. BACKGROUND OF THE INVENTION Wireless local area network technology is a wireless access technology widely used at present, which uses wireless signals to transmit user information. A typical wireless local area network includes a wireless access point (AP) and a user equipment (User Equipment, UE for short). The UE connects to the AP through a wireless network and is connected to the wired network by the AP. The WLAN protocol has been developed to face a small range of indoor application scenarios. In this scenario, it is necessary to consider the interference between various communication entities in the WLAN. For mobile user terminals (for example, mobile phones, handheld devices, etc.), Consider battery consumption; different countries have different requirements for the maximum transmit power of wireless LAN devices. Therefore, the transmission power of the WLAN device is limited. In China, for example, the effective omnidirectional radiated power (EIRP) of a typical AP is below 20 dbm, and the typical station (Station, referred to as STA). The EIRP is below 15dbm. Due to the limited transmit power, the coverage of wireless LAN devices is bound to be limited. The WLAN protocol defines different modulation rates for each standard. For example, llg products support 36Mbps 48Mbps, 54Mbps, etc. lln products support 6.5Mbps, 13Mbps 130Mbps, etc. Different modulation rates correspond to different modulation modes and codes. rate. In the same system, the higher the debugging rate, the higher the signal-to-noise ratio requirement. Conversely, the better the SNR condition, the higher the modulation rate supported. During signal transmission, the AP and the UE negotiate the modulation rate according to the channel condition, and improve the modulation rate by increasing the signal-to-noise ratio, thereby improving the performance of the system. The WLAN operates in accordance with the IEEE 802.11 series of protocols and operates in accordance with the Carrier Sense Multiple Access With Collision Avoidance (CSMA/CA) mechanism. In this mechanism, the communication entity is in peer-to-peer. Location, the communication entity in the common coverage area shares the channel. Any communication entity needs to perform carrier sensing before transmitting data. After listening to the channel idle, it can wait for a certain period of time before sending the data. At present, both the normal access point and the user terminal use an omnidirectional antenna. The characteristics of the omnidirectional antenna determine that the energy of the radio wave when the wireless local area network device transmits data is not only sent to the destination terminal, but around the transmitting end 360. Send within the space. In this way, on the one hand, the utilization of energy is not high (only a small part of the energy is received by the destination terminal); on the other hand, carrier sensing with collision avoidance Multi-access mechanism, when a terminal is sending data, all other terminals in its coverage need to be in the listening state, which reduces the performance of the system. As the number of WLAN devices increases, the probability of the device sharing the channel increases. Both the traditional access point and the user terminal use the omnidirectional antenna to adversely affect the user experience.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict. 1 is a block diagram showing the structure of a data processing apparatus for a wireless access point according to an embodiment of the present invention. The apparatus includes: a plurality of directional antenna groups 10, a plurality of radio frequency modules 20, a processor module 30, and an antenna logic control module 40. The plurality of directional antenna groups 10 are configured to perform signal coverage on the target area.

The auxiliary information is sent to the user equipment, and each of the radio frequency modules 20 corresponds to one directional antenna group 10; the processor module 30 is configured to receive uplink data and auxiliary information forwarded by the plurality of radio frequency modules 20, according to the uplink data. And the auxiliary information is selected for the user equipment to match the radio frequency module 20 of the user equipment, indicating that the radio frequency module 20 matching the user equipment sends the downlink data to the user equipment, and writes the logic control rule to the antenna logic control module 40 every predetermined time interval. The antenna logic control module 40 is configured to receive the logic control rule, and perform interference suppression on each of the radio frequency modules 20 according to the logic control rule. In the embodiment of the present invention, when the device completes signal coverage of the target area by using the plurality of directional antenna groups 10, each directional antenna group 10 covers a partial area of the target area, where each directional antenna group 10 The horizontal main lobe angles are the same or different; the parameters of each directional antenna group 10 match the parameters of the corresponding radio frequency module 20; the operating frequency band of each radio frequency module 20, medium access control (Media Access Control) , abbreviated as MAC) The addresses are the same. In a practical application, the multiple radio frequency modules 20 of the device may be directly or indirectly connected to the processor module 30 through a physical interface, where the physical interface includes at least one of the following: an Ethernet interface, a PCIE interface, a PCI interface, and a USB interface. Each RF module 20 includes: WLAN MAC/BB/RF chip, RC, Power Amplifier (PA), Low Noise Amplifier (LNA), filter, and electronics switch. 2 is a hardware schematic diagram of a data processing apparatus of a wireless access point according to a preferred embodiment of the present invention. As shown in FIG. 2, the apparatus adopts a hardware structure different from a normal AP including a multi-radio module. The AP hardware structure of the device is composed of a processor module, a radio frequency module group, a plurality of directional antenna groups, an antenna logic control unit, and other accessory accessories. The processor module is composed of a central processing unit (CPU), a memory (RAM), and a flash memory (FLASH). In practical applications, the processor module is mainly responsible for completing protocol processing, message processing, configuration management and the like. The device uses three sets of RF modules, each of which consists of a WLAN MAC/BB/RF chip, a PA, an LNA, a filter, and an electronic switch. Of course, in practical applications, you can also use the WLAN MAC/BB/RF chip with built-in PA and LNA. If you use a built-in chip, the peripheral device Pieces can also be reduced accordingly. The RF module group and the processor module are transferred through a converter (PCIe Switch), and the data is transmitted through the PCIe interface and the processor module. In the device, the directional antenna group has a one-to-one correspondence with the radio frequency module, that is, a group of radio frequency modules use a set of directional antennas, and the number and parameters of the antennas in each directional antenna group are matched with the parameters of the radio frequency module, specifically, each Each RF module group adopts a set of directional antennas with a horizontal main lobe of 120 degrees. The single RF module group completes coverage of 120 degree horizontal sectors. Different directional antennas are assembled in different range areas to cover, through three sets of RF modules and The directional antenna group combines the entire AP to achieve 360-degree omnidirectional coverage. The antenna logic control unit is implemented by Complex Programmable Logic Device (CPLD). The control logic (ie, control logic rules) is written by the CPU through the SPI interface. The antenna logic control unit is from the WLAN MAC/BB/RF chip. Read the transmit/receive (TX/RX) status information and frame type information stored in the chip, according to the control logic of the timing update (ie, the control logic rule, in practical applications, the processor module can move to the antenna logic every predetermined time interval) The control module writes new logic control rules to accommodate different control requirements when receiving different data. Controls the electronic switches and PAs in the RF module. The accessory accessories mainly include peripheral network interfaces (for example, GE interfaces for uplink networks) and device power supplies. The various components of the device and the working principle thereof will be specifically described below. In a preferred embodiment of the present invention, each set of radio frequency modules is externally connected with a set of directional antennas for generating signal coverage within a certain range, and different directional antennas cover signals in different range areas by using directional antennas. An antenna gain boost relative to an omnidirectional antenna can be obtained in the coverage area, thereby achieving higher link gain and better signal-to-noise ratio and transmission rate; interference sources for non-covered areas by directional reception characteristics of directional antennas The signal is suppressed, so that the AP is less affected by the interference source when receiving the UE data in the coverage area, thereby improving the signal-to-noise ratio and the transmission rate of the AP receiving direction, and also reducing the interference of the AP to the equipment outside the antenna coverage area. . In the device, the working frequency and the MAC address of the plurality of sets of radio frequency modules are set to be the same, so that the plurality of radio frequency modules operate in the same working mode. Since multiple sets of radio frequency modules are set to the same frequency and MAC address, for the UE, multiple radio frequency modules are one AP instead of multiple APs. In this case, the radio module associated with the UE is determined by the AP instead of being determined by the UE. When the UE roams in the AP coverage area, the AP may select according to the receiving condition of each radio module without affecting the UE receiving. The most suitable RF module sends data to the UE. The processor module may be configured to receive the WLAN management frame and the data frame received by each radio frequency module. For each UE, the processor module receives all the management frames and data frames of the UE that are received by the radio frequency module, because each radio frequency The range of coverage angles of the directional antennas connected to the module is different, and the processor module receives all the management frames and data frames received by the radio module, so the AP receives the data frames and management frames sent by the UE. The probability will increase, resulting in enhanced robustness of the AP uplink. The processor module filters the received management frame and data frame according to the MAC address, removes the duplicate frame, and then passes it to the upper layer protocol for further processing. At the same time, the processor module also receives additional signal quality information of the WLAN management frame and the data frame received by each radio frequency module to obtain real-time information of the best matching radio frequency module for each UE served. In particular, for all UEs associated with the AP, the processor module compares the signal quality of the data frame or the management frame of each UE received in each radio module in real time, thereby determining the received signal quality corresponding to each UE. The best RF module can be called a "matched RF module." In the apparatus, the matched radio frequency module can be used to transmit a unicast packet. For the downlink unicast packet, the processor module may be designated to be sent by the matched radio module, and for each unicast packet to be sent, the processor module finds and matches the address according to the destination MAC address of the unicast packet. The RF module is sent by the RF module. In this way, for the UE served by the AP, the most suitable directional antenna is used for data transmission, and the antenna gain of the omnidirectional antenna can be improved, thereby bringing link gain, signal to noise ratio, and downlink data. Increase in transmission rate. In the device, all the radio frequency modules can implement the transmission of the broadcast packet, and the broadcast packet can be repeatedly transmitted. For downstream broadcast packets (eg, beacon frames), it is copied by the processor module to all RF modules, and the broadcast packets are repeatedly transmitted by the RF module. The broadcast packet is sent for the entire coverage area of the AP. When the processor module detects that the downlink packet is a broadcast packet, the processor module copies the broadcast packet to the radio module for time-sharing, and each radio module is sent. The signal transmission between them follows the CSMA/CA mechanism. The RF module can also process the control frame signal autonomously. When the radio module receives the control frame sent by the UE, the control frame is automatically sent. For example, the radio module automatically responds to the ACK frame after receiving the unicast frame signal sent by the UE. The antenna control logic module can be used to suppress interference that may occur between the various radio frequency modules. The antenna control logic module receives the transmission/reception status information of each radio frequency module, and controls the electronic switch or the PA component of each radio frequency module according to the control logic written by the processor module, for example, when a certain UE sends a unicast packet to the AP. The radio module of multiple APs may receive this message and are ready to reply to the ACK signal. When the antenna control logic module detects that a radio module is replying to the control signal, it can make the ACK of other radio module through the electronic switch or PA. The signal cannot be transmitted through the air interface to prevent the multiple RF modules from returning the ACK signal, which may cause the UE to fail to receive the ACK signal normally. FIG. 3 is a schematic diagram of an application scenario according to an embodiment of the present invention. As shown in FIG. 3, a combination of three sets of radio frequency modules and directional antenna groups of an AP forms three covered sectors, and 360 is formed by three sectors. Degree Omnidirectional horizontal coverage; wherein each sector is covered by a set of RF modules and directional antenna groups, which are 1# area, 2# area, and 3# area, respectively. Since the directional antenna can obtain a higher horizontal lobe maximum gain with respect to the omnidirectional antenna in the same standing wave ratio and vertical lobe, the device can obtain the highest log3 4.78db relative to the device using the omnidirectional antenna. The gain is increased, which is suitable for the upstream and downstream directions, and can achieve a maximum coverage distance increase of more than 30% and a maximum coverage area increase of more than 80%, respectively. In the application scenario shown in Figure 3, three radio modules are set to work in the same frequency and the same MAC address. When the AP communicates with the UE in its coverage area, it can select the optimal according to the control of the program. The radio module sends data. In this scenario, the parameters displayed by the radio module for the UE are completely consistent. Therefore, UE1, UE2, and UE3 do not know which radio module to communicate with. The data processing device of the wireless access point provided by the foregoing embodiment can enhance the coverage of the single AP without increasing the bandwidth occupation, and improve the uplink and downlink link gains of the AP, thereby improving the uplink and downlink rates. The AP capacity, as well as the anti-jamming capability of the AP, reduces the interference between the APs, thereby improving the user experience and system performance of the WLAN. 4 is a flowchart of a data processing method of a wireless access point according to an embodiment of the present invention. As shown in FIG. 4, the method mainly includes the following steps (step S402 - step S406): Step S402, each radio frequency module passes the same The corresponding directional antenna group receives uplink data from the user equipment, parses the auxiliary information of the uplink data from the uplink data, and forwards the uplink data and the auxiliary information to the processor module. Step S404, the processor module selects, according to the uplink data and the auxiliary information, the radio frequency module matched to the user equipment for the user equipment. Step S406: The radio frequency module matched to the user equipment sends downlink data to the user equipment. In step S404, the processor module selects, for the user equipment, the radio frequency module that matches the user equipment according to the uplink data and the auxiliary information, where the processor module filters the uplink data according to the MAC address, and deletes the duplicate data in the uplink data. The module module parses the signal quality information of the uplink data from the uplink data and the auxiliary information; the processor module determines the radio frequency module matched to the user equipment according to the signal quality information. Preferably, after the step S404, the method further includes: the processor module sends the uplink data after the deduplication is deleted to the upper layer protocol for processing; the processor module accepts the data delivered by the upper layer protocol; and the processor module delivers the upper layer protocol The data is forwarded as downlink data to the radio frequency module that matches the user equipment. The signal quality information includes one of the following: signal strength RSSI, signal to noise ratio SR. 5 is a schematic flowchart of processing a received data frame in the application scenario shown in FIG. 3. As shown in FIG. 5, the radio frequency module 1 receives three data frames sent by the UE1, and the data frame numbers are respectively packet 1. Packet2, packet3 _{; The} radio module 2 receives a total of 6 data frames sent by UE1 and UE2, respectively, which are packet 1, packet 2, packet 3 and packet 4, packet 5, and packet 6 sent by UE1; radio module 3 receives UE3. The four data frames sent, the data frame numbers are packet 7, packets, and packets pa _C ketlO. The processor module receives the frame received by the radio frequency module. Since there are duplicate frames for the UE1 in the radio frequency module 1 and the radio frequency module 2, the processor module removes the duplicate frame according to the MAC address and the frame number, and then sends the frame to the upper layer protocol for further processing. In the process, the processor module determines a matching relationship between the UE and the radio frequency module according to the source radio frequency module of the received frame and the frame signal quality information. For example, the frame of the UE3 is reported by the radio frequency module 3, and the radio frequency module matching the UE3 is the radio frequency module 3; the frame of the UE2 is reported by the radio frequency module 2, and the radio frequency module of the UE1 is the radio frequency module 2; Module 1 and RF module 2 both report the frame of UE1, and then need to judge the matched RF module according to the frame signal quality information (which can be determined according to signal strength (RSSI) or signal-to-noise ratio (SR)). In this example, the radio frequency module 1 receives the UE1 frame signal quality better than the radio frequency module 2 receives the UE1 frame signal quality, determines that the radio frequency module matching the UE1 is the radio frequency module 1, and the processor module will update this information in real time and store the spare. . 6 is a schematic flowchart of processing a unicast frame to be sent in the application scenario shown in FIG. 3. As shown in FIG. 6, the processor module receives 10 data frames sent by the upper layer protocol to the UE, and the data frame numbers are respectively For packetl-packetlO, each data frame contains the destination MAC address of the UE to be transmitted. The processor module queries the matching radio frequency module number for the MAC address according to the destination MAC address of each data frame (such as UE1 matching radio frequency module 1 described above, UE2 matching radio frequency module 2, UE3 matching radio frequency module 3), and according to the corresponding The number sends the data frame to the send queue of the corresponding radio module. The packet _e tl~p _aC ket3 is sent to the sending queue of the radio frequency module 1, the packet4~packet6 is sent to the sending queue of the radio frequency module 2, and the packet7~packetl0 is sent to the sending queue of the radio frequency module 3. Each RF module transmits data frames in a time-sharing manner according to the CSMA/CA mechanism defined by 802.11. In this way, the purpose of directional transmission is achieved, and the performance of the downlink link is improved. Preferably, for a broadcast frame signal (for example, a beacon frame beacon signal), the processor module copies it to each radio frequency module, and the radio frequency module transmits the broadcast frame signal in time division. Preferably, for the control frame signal, it can be processed autonomously by the radio frequency module. For example, the radio module automatically responds to the ACK frame after receiving the unicast frame signal sent by the UE. In this case, it is easy for a radio module that has multiple APs to receive this message when a certain UE sends a unicast packet to the AP and is ready to reply to the ACK signal. When the antenna control logic module detects that a certain RF module is replying to the control signal, it can be controlled (turned on or off) Close) The electronic switch or PA can make the ACK signal of other RF modules unable to transmit through the air interface, so as to avoid multiple RF modules returning the ACK signal, which may cause the UE to fail to receive the ACK signal normally. The data processing method of the wireless access point provided by the foregoing embodiment can enhance the coverage of the single AP without increasing the bandwidth occupation, and improve the uplink and downlink link gains of the AP, thereby improving the uplink and downlink rates. The AP capacity, as well as the anti-jamming capability of the AP, reduces the interference between the APs, thereby improving the user experience and system performance of the WLAN. From the above description, it can be seen that the present invention achieves the following technical effects: The data processing apparatus and method for the wireless access point provided by the foregoing embodiments, the AP having multiple directional antennas relative to the use of the common omnidirectional antenna The AP can obtain a gain increase of more than 4.7 db in both the uplink and downlink directions, and can obtain a maximum coverage distance increase of more than 30% and a maximum coverage area increase of more than 80%, respectively; the interference to the outside world is reduced by 60% in the downlink direction, and is improved. AP uplink anti-jamming capability and hidden node processing capability. Moreover, compared with the AP using the ordinary omnidirectional antenna, the amount of hardware and software changes is small, the performance of the product is obviously improved, and the value of the scale promotion application is large. Obviously, those skilled in the art should understand that the above modules or steps of the present invention can be implemented by a general-purpose computing device, which can be concentrated on a single computing device or distributed over a network composed of multiple computing devices.
