Description
Technical field
The present invention relates to wireless communication field, relates generally to the encapsulation and data interaction of wireless protocols, is a kind of base
In the CPE tuning methods of radio detection.
Background technology
CPE is customer terminal equipment in a communications system.In recent years, with the popularization of the mobile terminals such as mobile phone, computer, people
Become more and more higher for the smooth demand for playing network, especially for being even more on the outskirts of a town, under these markets potential in rural area such as
This.Due to having inconvenient traffic, difficult wiring, operator needs to reduce the cost for carrying out cable network laying under these circumstances, because
This widely used base station adds CPE laying method.In this way, can not only increase the coverage of wireless signal, and reduce
The running cost of operator.But the particularity of the installation site due to CPE, it result in when mounted because remote bad visibility
It is bad to result in antenna direction adjustment, so as to which the user for being not reaching to optimal performance and having had influence on the later stage uses.Meanwhile when
It is specific to investigate reason trouble when circuit goes wrong, considerably increase the workload of investigation concrete reason.
The content of the invention
In order to solve the deficiencies in the prior art, the maintainability of system is improved, the present invention provides one kind and is based on radio detection
CPE tuning methods, after this method installation system, engineering staff being capable of key detection customer terminal equipment CPE and base
The performance indications stood between AP, the adjustment of convenient construction personnel travel direction, improve the engineering efficiency of CPE layings.
The technical scheme is that：A kind of CPE tuning methods based on radio detection, nothing is gathered by wirelessly driving
Line data message, the data collected are sent to User space by NETLINK, and concentrated in together by network service；Should
Method includes：
Base station AP is accessed by wlan network and customer terminal equipment CPE phases, forms AP/CPE end system frameworks；
AP/CPE end systems framework includes three parts, and it is respectively in User space process airoclient, airokernel
Core module and wireless driving wireless driver；
Wireless driving wireless driver are responsible for providing wireless register information；Airokernel kernel modules are responsible for
User space process airoclient NETLINK communication SOCKET are managed, and provide intermediary interface to wireless driving wireless
Driver carries out wireless event and air message reports；
Operation airoclient processes in the AP of base station, the process pass through in wlan network and customer terminal equipment CPE
Airoclient processes are in communication with each other, after customer terminal equipment CPE receives the data of base station, on the one hand by data with curve map
Form be shown in WEB page, on the other hand send the data to the airoserver processes at PC ends, PC ends receive data it
Afterwards, file is saved as, carries out analysis and the positioning problems of message by specific software for workmen；
The airoclient processes of operation are by specifying different operational factors in customer terminal equipment CPE so that
Airoclient plays the part of three different roles：The air message person of reporting, radio capability data collection terminal and radio capability data
Service end；
When airoclient plays the part of the air message person of reporting role, it, which forms each object, is respectively：netlink
Socket and wireless pkt reporter；
Netlink socket are NETLINK communication objects, responsible and kernel communication；
Wireless pkt reporter are that wireless packet data reports object；When airoclient carries out air message
On give the correct time, object is reported by wireless pkt reporter, airoserver is connected, is taken away from pkt queue queues
The air message of netlinkw storages, is reported to airoserver；
When airoclient plays the part of data acquisition end role, it, which forms each object, is respectively：wireless
Event report service and p2p test speed service；
Wireless event report service are wireless event report services objects；When airoclient is realized
During radio capability data service function, wireless performance data is read from wireless event data data fields by this object,
Collection terminal is reported by TCP connections；
P2p test speed service are the point-to-point service units that tests the speed；The negotiation ginseng for the client that tested the speed according to P2P
Number, random data is sent, or receive the data from the other end that tests the speed, it is common to coordinate the bandwidth test for completing Radio Link；
When airoclient plays the part of radio capability data service end role, it, which forms each object, is respectively：server
Event receiver, p2p test speed client and CPE UI Displayer；
Server event receiver are the wireless event objects that the reception server reports；When airoclient is realized
During radio capability data collection service, by this object peer end of the connection, the NETLINK wireless performance event datas of opposite end are obtained；
P2p test speed client are the point-to-point service clients that tests the speed；Get parms, be sent to from order line
The point-to-point service unit that tests the speed, parameter negotiation is completed, retransmit random data, or receive the data from the other end that tests the speed, altogether
With the bandwidth test for coordinating completion Radio Link；
CPE UI Displayer are CPE interface display objects, are responsible for showing the data wirelessly reported and measurement data
To interface, shown at interface above with the mode of bar chart；
When carrying out wirelessly catching packet stream journey：
Airoclient plays the part of the air message person of reporting role in CPE, establishes and connects with airoserver, and establishing will be wireless
Data message is sent to airoserver passage；
Airoclient is connected by NETLINK and Linux kernel registrations；
The wireless data message received is sent to airoclient by wireless driving wireless driver；
Airoclient sends the wireless data message received from wireless driver to airoserver,
Airoserver is converted to obtained air message the file of TCPDUMP forms；
When progress base station AP to CPE wall scrolls flow down the calculating of row throughput：
Airoclient is run at base station AP ends, plays the part of radio capability data service end, creates SOCKET, initializes kernel
NETLINK communication connection, into intercepting service state；
Airoclient is run in cpe end, plays the part of radio capability data collection terminal role, initialization P2P tests the speed parameter association
Business is the descending communication connection tested the speed, initialize kernel NETLINK；
Airoclient in CPE establishes a session of testing the speed, and enter loop test shape according to concurrent fluxion with AP
State；
The socket writing buffers that judgement is tested the speed in the AP of base station are writeable, produce random data, and send data to CPE；
Meanwhile AP timings in base station obtain radio capability data by wireless driver, acquiescence timing is 1 second；
Timing is driven the radio capability data obtained to send to CPE by base station AP；
CPE carries out computing according to the radio capability data reported, and result is included on CPE UI interfaces；
Being shown in content on CPE UI interfaces mainly includes：Downstream rate, RSSI the and TX speed at AP ends, local terminal
RSSI and TX physical rates, when tested between to when, Mean Speed will be shown.
