Remote control center comprises radio control server (AccessController, AC) and database.Remote control center disposes public transport WLAN management platform, and for administering and maintaining each WLAN base station, its concrete methods of realizing will be described in more detail below.
Fig. 2 shows the structural representation of the WLAN base station in an embodiment.WLAN base station comprises WAP (wireless access point) (AccessPoint, AP), media server (MediaServer) and 3G assembly.3G assembly comprises: the modules such as TDSDMA, WCDMA, is connected by PCIE bus with AP, for the 3G network of access carrier.3G signal is converted to public WIFI signal by WIFI module by WLAN base station.WIFI module, as translating bridge, is changed and bridge joint the frame from different medium at link layer, is bridged in internet by wireless data by 3G network.Multimedia server, based on the streaming video service system of http protocol, by http protocol streaming media data, thus realizes transmission and the broadcasting of HD video.The form that video playback adopts random position to play, plays a time point that can be random from play content.MediaServer is connected to WIFI module by LAN, thus realizes wireless universal broadcasting.User uses and supports that the terminal equipment of http protocol just can access vehicle-mounted WLAN base station by wireless network and view and admire the HD video that built-in MediaServer provides.In one embodiment, MediaServer realizes needs 3 key elements of the function that HD video is play: server end, client and streaming video content.Server end provides the service of customer in response end request, to client transmissions streaming visual data; Client initiates the request to particular content to service end, and accepts by the next stream data of wireless network transmissions.Streaming video content is that its form of expression is the special file of separate, stored with the video data file of certain format coding.Streaming video content adopts general format.Content of multimedia to be read the multimedia server that provides from east by internet and is automatically upgraded.
With reference to figure 3, on a concrete hardware implementing, MediaServer comprises risc processor and connected synchronous DRAM, main storage, flash memory, safe digital card and real-time clock module, main storage is used for depositing the Software Mirroring of whole system, flash memory is used for the configuration of saved system, and safe digital card is used for depositing content of multimedia.Risc processor has asynchronous serial communication interface and ethernet controller, is respectively used to connect serial port and local area network (LAN).Serial communication interface is used for debugging.MediaServer is used for the coding and decoding of content of multimedia and provides multimedia service.
With reference to figure 4, on a concrete hardware implementing, AP comprises risc processor and connected synchronous DRAM, main storage, flash memory, real-time clock module, radio modem (can adopt the chip based on 802.11 agreements) and 3G assembly.Risc processor has asynchronous serial communication interface and ethernet controller, is respectively used to connect serial port and local area network (LAN).
In above-described embodiment, the public transport WLAN management platform of being disposed by remote control center administers and maintains each WLAN base station.The public transport WLAN management platform being positioned at data center realizes monitoring and management by IP network: (1). the WLAN base station running status in monitoring public transport, and realize remote base stations maintenance function.(2). monitor user's service condition of each WLAN base station.(3). centralized configuration and management WLAN base station.(4). concentrate real-time upgrading software.
Management platform timing to base station send instruction, frequency be every 10 seconds once, base station sends feedback information according to command content to management platform, reports the state of oneself.According to the data returned, the staff of data center judges that whether base station operation is normal.The generic route encapsulation (GRETunnel) of public transport WLAN management platform can transmit multipoint sending data bag; The encryption method of IPSec is used to be encrypted GRETunnel, for safety office subsystem provides a safe and reliable VPN.Public transport WLAN management platform can implement user authentication, and plays gateway function between WLAN and Internet, the data from diverse access point is carried out converging, accessing Internet.
In one embodiment, the method for public transport WLAN management platform monitoring WLAN base station is as follows:
Wlan base station regularly by the state information of oneself inside, can be transferred to remote control center by udp protocol.The transmission of these data does not need remote control center to respond.Wlan base station sends to the data type of remote control center to comprise:
Current user information: the IP address of user, MAC Address, the information such as flow;
The radio network information that current Wlan base station scans obtains: AP information around, disturbed condition, the information such as the attack detected;
Remote control center, after discovery is by software upgrading or config update, can send upgrade command to Wlan base station, after Wlan base station receives upgrade command, according to ordering the information of carrying, download software and configuration, upgrade from the position of specifying, and autoboot.
System of the present invention achieves the functions such as Wireless Mobile Office in car, wireless Internet access and amusement.Be installed in public transport, the surfing the web of passenger can be met, watch the functions such as video.The passenger taking public friendship only need have the equipment of a band WIFI function, by native system, just can be joined seamlessly to Internet whenever and wherever possible, realize various network function; Also can be connected on multimedia platform that native system carries, watch built-in multimedia video and browse built-in Domestic News.
Compared with prior art, the present invention has many advantages, is specifically described as follows:
1. creativeness is proposed built-in multimedia video broadcasting.
Current in-vehicle wireless device can only provide the function of online, and east is read onboard wireless and additionally provided multimedia video and play, only need connect native system with wireless network, can the built-in multimedia hub of connection device, random program request HD video.Exquisite smooth picture makes user can enjoy the comfortable and efficient of amusement and recreation of being in.The renewal of film source is convenient and swift equally, only need regularly replace storage medium.The advanced renewal along with software, can real-time update film source, realizes by several functions such as program request rate sequences.
2. distinctive management platform
Can controlling apparatus remote, manage and software upgrading, without the need to implementing to upgrade to each point, only needing Telnet to realize.The state of equipment can be detected in real time, management AP, is configured; For the AP running into fault, can remote reboot, detection failure repair (hardware damage except).Can also detect the service condition of user simultaneously, employ native system if any how many users simultaneously, which is the period that occupancy is higher period, can do corresponding adjustment according to the demand of user.A control appliance can connect at most 512 mobile units.
3, provide special VPM passage to realize public transport internal control, realize efficient wireless office.As the work attendance of driver, the situation of relieving of driver, the ruuning situation of car load, thus the operational management realizing public transport group internal.Can priority be set, office data is preferentially sent.So this product mainly for be the user of enterprise-level, and onboard wireless product on market mainly for be personal user.
For being more convenient to understand, table 1 gives the contrast of WLAN base station of the present invention and Huawei E5.
Table 1
Finally it should be noted that, above embodiment is only in order to describe technical scheme of the present invention instead of to limit this technical method, the present invention can extend in application other amendment, change, application and embodiment, and therefore think that all such amendments, change, application, embodiment are all in spirit of the present invention and teachings.
