Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a wireless network deployment method and a wireless access point.
Background
In the networking of the existing wireless networks such as WLAN and WIFI, the networking is generally realized by a wireless Access Point (AP) and a wireless controller (AC). In the networking mode of AC + AP, the AP is only responsible for receiving and sending signals, and the AC is responsible for the functions of client identity authentication, security policy management and the like. After the AP is started, it is necessary to find an accessible AC through AC auto-discovery, establish a connection with one of the ACs, and download a required AP configuration from the AC to provide a wireless access service, but not to provide a service alone. The AC and the AP may establish connection and communicate through a lightweight access point protocol (LWAPP) or a wireless access point control and provisioning (CAPWAP) protocol.
The WLAN network has the characteristics of easy deployment, mobility, etc., and the application range is becoming wider and wider. Not only the enterprise network needs to deploy the WLAN, but also the urban wireless network, education, personal office and other aspects, and the WLAN network is not used everywhere.
In terms of city hotspots, education, even places including hotels, airports, etc., these places are typically operators that offer public services. For any operator, there is a desire to provide ubiquitous services, these places being first of all places to be covered. Operators take advantage of WLAN coverage to distribute data traffic pressure of 3G networks. This has resulted in one such result: the WLAN networks in these places have multiple network coverage, and the networks of different operators are physically independent from each other, which results in duplication of infrastructure construction, and the WLAN networks themselves interfere with each other, resulting in not very ideal effect.
There are even some locations, such as hotels, that want to build their own operating network while providing the customer with operator network coverage. The convenience and rapidity of using a WLAN to improve its own service management is apparent. If a hotel is a branch location, they often need to connect to the headquarters and interact with the headquarters directly in real time. If each builds a different WLAN network on its own, it obviously results in duplication and is difficult to maintain. If only one WLAN network is established, it may result in incomplete service or difficulty for each home to maintain its own service independently.
Referring to fig. 1, fig. 1 is a schematic diagram of a network structure in which multiple operators deploy wireless networks in the same area according to a conventional wireless network deployment method. As shown in fig. 1, in area a, there are two wireless networks deployed by two operators, AC of the two operators are AC110 and AC120, respectively, AC110 deploys two APs, AP111 and AP112, respectively, in area a, and AC120 deploys two APs, AP121 and AP122, respectively, in area a. As can be seen in fig. 1, in area a there are multiple sets of APs of multiple operators that provide services, and each operator controls the AP that it deploys via a respective AC. However, since the wireless channel resources are limited, if too many APs in the same area exist, the phenomena of mutual signal interference, packet error or packet loss will be very serious, resulting in network performance degradation.
Disclosure of Invention
In view of this, the present invention provides a wireless network deployment method and a wireless access point, which can avoid repeated construction and reduce interference between WLAN networks.
In order to solve the technical problem, the technical scheme of the invention is realized as follows:

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the embodiments of the present invention will be described in detail with reference to the accompanying drawings.
The invention provides a wireless network deployment method, in the wireless network, an AP can establish connection with a plurality of different management entities simultaneously, and can provide wireless services from different management entities to a wireless terminal simultaneously, wherein the management entity refers to an entity unit, has a network of the management entity, can provide network services independently, and implements an independent network management strategy. In an embodiment of the present invention, a management entity owns one or more ACs and can provide its own independent wireless services, such as an operator, a company headquarters, etc., using a common AP.
Referring to fig. 2, fig. 2 is a flow chart illustrating a wireless network deployment method according to an embodiment of the present invention. The method comprises the following specific steps:
in step 201, the AP determines whether there is a master management AC in the ACs of multiple different management entities, if so, step 202 is executed, otherwise, step 204 is executed.
In this step, the determining, by the AP, whether a master management AC exists among the ACs of the plurality of different management entities includes: the AP obtains information of a plurality of management entities configured locally or sent by the DHCP server, and determines whether to designate a main management entity according to the information, wherein the AC of the management entity designated as the main management entity is a main management AC, and the AC of the management entity not designated as the main management entity is a common AC.
In the specific implementation, the information of different management entities can be configured on the AP in advance and directly acquired; or the DHCPACK message can be configured on a DHCP server, the AP is on line, and when the AP interacts with the DHCP server, the information of different management entities carried in the DHCPACK message sent by the DHCP server is received. The information of each different management entity includes its name, the IP address of the AC, and whether a certain management entity is designated as the master management entity. If the different master management entities specify the master management entity, the AC of the master management entity is the master management AC.
And if the number of the ACs of any one of the management entities is more than one, determining that one of the ACs is a main AC and the other ACs are backup ACs. If the main AC is the main management AC, the AP receives and takes effect the AP management configuration information and the wireless service class management configuration information sent by the main AC; otherwise, receiving and validating the wireless service class management configuration information sent by the main AC.
If a certain management entity in the plurality of management entities designates a plurality of ACs, the plurality of ACs are in backup relation, one of the ACs is designated as a main AC, and the AP establishes connection with all the ACs of the management entity or only establishes connection with the main AC. Only the configuration information sent by the main AC is received and validated, whether or not a connection is established with other ACs. If the management entity where the main AC is located is exactly the main management entity, receiving and taking effect the AP management configuration information and the wireless service class management configuration information sent by the main AC; if the management entity where the main AC is located is not the main management entity, that is, the main AC is not the main management AC, only the wireless service class management configuration information sent by the main AC is received and validated.
Step 202, the AP establishes a connection with the master management AC, and receives and validates the AP management configuration information and the wireless service class management configuration information sent by the master management AC.
Step 203, when the connection established between the AP and the master management AC is in a run state, establishing connections with other ACs respectively, receiving and validating the wireless service class management configuration information sent by the other ACs, and ending the process.
The run state in this step refers to a stable operation state that the AP enters after discovering the wireless controllers and performing links such as parameter negotiation through a specific protocol between them, such as CAPWAP, and at this time, the AP has already established a communication tunnel with the AC and has received initial configuration parameters of the AC.
And step 204, the AP validates the AP management configuration information configured by the AP, establishes connection with the plurality of ACs respectively, and receives and validates the wireless service class configuration information of the plurality of ACs.
In this step, if there is no main management AC in the ACs of the multiple management entities, the AP validates the AP management configuration information configured in advance, and then establishes connections with the ACs of each management entity respectively.
Wherein the AP management configuration information includes: radio frequency configuration information, mapping file information, wireless security information, wireless environment report information, and time information of the master management AC. The radio frequency configuration information comprises a channel, transmission power, radio frequency management, bandwidth and the like; the mapping file information includes the version of the mapping file, whether the mapping file is upgraded, and the like.
The wireless service class management configuration information includes: service Set Identification (SSID) management information, wireless terminal management information, and access control policy information for a wireless terminal or SSID. The SSID management configuration information includes SSID names, wireless terminal management information, and access control policy information of the wireless terminal or the SSID is a function implemented based on the SSID.
And if the AP configures the wireless service class management configuration information, the configured wireless service class management configuration information is validated, wherein SSID names in the SSID management configuration information of the AP and the ACs are different.
And when the messages are interacted between the wireless terminal and the AC of the management entity, determining whether the wireless terminal forwards the messages to the corresponding AC or locally forwards the messages according to the SSID. Due to the fact that SSID names are different and uniqueness exists, the AP can prohibit the message of the wireless terminal under the wireless service corresponding to one management entity from being forwarded to the wireless service of another management entity, namely, the flow of the wireless terminal under different management entities is strictly isolated. There is also strict isolation between them and the traffic of the AP's own wireless services. The management of the AP with respect to each VLAN is related to the management entity, i.e. traffic of the same VLAN under different management entities must not be forwarded to each other.
The AP receives the association information of the wireless terminal and associates the source MAC address of the wireless terminal with the corresponding SSID name;
when receiving a message sent by a wireless terminal, the AP searches a corresponding SSID name according to a source MAC address of the message, determines whether the searched SSID name is a self-configured SSID name, and if so, converts the message into an MAC format corresponding to a wired system and forwards the message to a wired network; otherwise, according to the wireless service class management configuration information of the AC corresponding to the SSID name, the information is forwarded to the AC through a CAPWAP tunnel between the AC and the AC corresponding to the SSID name, so that the AC forwards the message to a wired network, or the message is converted into an MAC format corresponding to the wired network and is forwarded to the wired network.
If the found SSID name is corresponding to the message issued by the AC, determining whether the message sent by the wireless terminal in the wireless service management configuration information issued by the AC is locally forwarded or intensively forwarded, if the message is locally forwarded, converting the message into an MAC format corresponding to a wired network, and directly forwarding the message to the wired network; if the message is forwarded in a centralized way, the message is forwarded to the AC through the connection established between the AC and the AC corresponding to the SSID name, so that the AC forwards the message to the wired network.
Referring to fig. 3, fig. 3 is a schematic diagram of a network structure in which different management entities deploy wireless networks in the same area according to an embodiment of the present invention. In fig. 3, AC311 is an AC of management entity 1, AC312 is an AC of management entity 2, wireless terminal 321 and wireless terminal 322 are wireless terminals of management entity 1, wireless terminal 323 is a wireless terminal of management entity 2, and wireless terminal 324 is a wireless terminal of AP 300.
Referring to table 1, table 1 is an address table entry in the embodiment of the present invention. When the local socket in table 1 is established, tcp/udp, the local IP, the peer IP, the local port number, and the peer port number are bound. Of course, the peer port number, AC, is generally known, e.g., CAPWAP uses UDP 5276/5277. The local port number is randomly selected and the local IP needs to confirm which IP address is appropriate for use depending on the route.
| Management entity | IP address | State of tunnel | Local socket number |
| Management entity 1 | IP Address of AC311 | Run | 1 |
| Management entity 2 | IP Address of AC312 | Run | 2 |
TABLE 1
Referring to table 2, table 2 is a wireless service management table entry in an embodiment of the present invention. In table 2, the management entity 1 issues centralized forwarding and local forwarding in two forwarding forms, and the AP also configures an SSID for its own local forwarding.
| Numbering | Name (R) | Management entity | Centralized/local | Default VLAN |
| 1 | SSID1 | Management entity 1 | Centralizing | 1 |
| 2 | SSID2 | Management entity 1 | Local area | 2 |
| 3 | SSID3 | Management entity 2 | Centralizing | 2 |
| 4 | SSID4 | Local AP | Local area | 3 |
TABLE 2
And aiming at the association of each wireless terminal and each management entity, the AP establishes a wireless terminal management table for each management entity respectively. Referring to table 3, table 3 is a management table of the wireless terminal of the management entity 1 in the embodiment of the present invention; table 4 is a wireless terminal management table of the management entity 2 in the embodiment of the present invention; table 5 is a wireless terminal management table local to the AP. The specific table is as follows:
| wireless terminal address | SSID | VLAN |
| MAC Address of Wireless terminal 321 | SSID1 | - |
| MAC address of wireless terminal 322 | SSID2 | 2 |
TABLE 3
| Wireless terminal address | SSID | VLAN |
| MAC Address of Wireless terminal 323 | SSID3 | - |
TABLE 4
| Wireless terminal address | SSID | VLAN |
| MAC Address of Wireless terminal 324 | SSID4 | 3 |
TABLE 5
In table 3 and table 5, when each wireless terminal establishes a connection, if a VLAN is not obtained, a default VLAN is used, and if forwarding is centralized, the VLAN does not need to be recorded.
When the AP300 receives a message sent by the wireless terminal 324, finds a corresponding SSID name in the wireless management terminal table according to a source MAC address carried in the message, and when the MAC address of the wireless terminal 324 is found to correspond to the SSID4, determines that a management entity of the SSID4 is the AP itself, determines that the message needs to be locally forwarded, locally converts the message into a MAC format corresponding to a limited network, such as an 802.3 format of ethernet, and forwards the message to the wired network in fig. 3, where the message is not forwarded to the AC311 of the management entity or the AC312 of the management entity.
When the AP300 receives a message sent by the wireless terminal 321, the corresponding SSID name is found in the wireless terminal management table according to the source MAC address carried in the message, and when the MAC address of the wireless terminal 321 is found to correspond to the SSID1, it is determined that the corresponding SSID1 is the SSID name of the management entity 1 where the AC311 is located, and the configuration of the AC311 to the wireless terminal 321 is correspondingly recorded in the wireless service management table and is forwarded in a centralized manner, so that the message is forwarded to the AC311 through the connection established between the AC311 and the AP300, and the AC311 forwards the message to a wired network, and does not forward the message to the ACs of other management entities or forward the message locally. Therefore, the message is transmitted and separated between different management entities. The process of receiving the wireless terminal 322 and the wireless terminal 323 by the AP300 is the same as above, and is not described in detail here.
In the specific implementation of the present invention, only the AP configuration management information of the master management AC will take effect, and if there is no master management AC, the AP configuration management information of the AP itself will take effect. Based on the invention, two implementation modes are provided, one mode is to receive the AP management configuration information sent by all the ACs, but only the AP management configuration information of the main management AC is validated, and the AP management configuration information sent by the common AC is ignored. Another implementation is to notify the master AC to send AP management configuration information, and notify the normal AC not to send AP management configuration information. The concrete implementation is as follows:
when the AP establishes connection with the main management AC, the main management AC is informed to serve as the main management AC, and the main management AC is enabled to send AP management configuration information; when the AP establishes connection with the common AC, the common AC is informed to serve as the common AC, so that the common AC does not send AP management configuration information.
If the main management entity is not designated in the plurality of different management entities, the ACs of all the management entities are informed not to send the AP management configuration information, or the AP management configuration information sent by the ACs of all the management entities is ignored.
The configuration information which is the same as the configuration information of the existing management AC is issued by each AC, and the information which is sent by the main management AC is only validated after the AP receives the configuration information, but the configuration information which is issued by the common AC is ignored.
The joining request and joining response process is the same as the original CAPWAP protocol, and the AP needs to tell the AC through the interaction process, and whether the opposite side is the main management AC or the common AC. In particular, the implementation can be realized by utilizing vendor custom element (VendorSpecificPayload).
In the configuration state request and configuration state response processes, the main management AC issues the following elements in the configuration state response message, the AP receives and takes effect, and the elements issued by other ACs are ignored. The method comprises the following specific steps:
IEEE802.11Antenna
IEEE802.11DirectSequenceControl
IEEE802.11MACOperation
IEEE802.11Multi-DomainCapability
IEEE802.11OFDMControl
IEEE802.11RateSet
IEEE802.11SupportedRates
IEEE802.11TxPower
IEEE802.11WTPRadioConfiguration
in the configuration update request and the configuration update response process, the AP receives each AC delivery, only validates the master management AC delivery, ignores other ACs deliveries, and has the following specific information:
ACTimestamp
RadioAdministrativeState
ImageIdentifier
IEEE802.11Antenna
IEEE802.11DirectSequenceControl
IEEE802.11MACOperation
IEEE802.11Multi-DomainCapability
IEEE802.11OFDMControl
IEEE802.11RateSet
IEEE802.11SupportedRates
IEEE802.11TxPower
IEEE802.11WTPRadioConfiguration
during the image data request and image data response, the version of the AP can only be upgraded or downgraded, or managed locally, by the primary management AC.
The AP only processes the reset request and the reset response of the master management AC, ignoring the messages issued by other ACs.
In the WLAN configuration request and WLAN configuration response process, when any AC issues a request, it needs to determine whether the SSID names of other management entities and local configuration are consistent. If so, the WLAN configuration response results in failure. I.e. the case where the same name does not exist for different management entities and local SSID names.
In the event request and event response process, the interaction on the aspects of wireless security and wireless environment report is only carried out with the main management AC.
In the process of the station configuration request and the station configuration response, any management entity can only add and delete the wireless terminal of the management entity, but cannot manage the wireless terminals of other management entities.
In the process of clearing the configuration request and the clearing the configuration response, when a clear configuration request message sent by a certain AC is received, only all configuration information related to the AC is cleared. The configuration information issued by other ACs is not affected.
