Abstract

A wireless repeater device makes it possible to access the internet from a wireless LAN terminal, and notifies the state of wireless connection to a public wireless transmission network to the wireless LAN terminal, thereby alleviating uncertainty and disquiet on the part of the user when connecting to this network.The wireless repeater device detects the external network utilization information and notifies it to the wireless LAN terminal. When a terminal device has made a connection request, an authentication section authenticates the terminal device, based upon authentication information which has been stored in a storage section in advance. And an encoding section executes an encoding procedure based upon a code which has been stored in the storage section in advance. By doing this, leakage of the authentication information is prevented. The wireless LAN terminal registers getting off reservation information and its own specific recognition code in advance. When a vehicle approaches a stopping point, the recognition code is verified and the getting off reservation information is notified to the wireless LAN terminal. By doing this, it is possible for the passenger who owns the wireless LAN terminal to get off at his desired stopping point.

The application application for a patent for invention No.200410047695.5 that is entitled as " radio communications system " that to be on May 26th, 2004 submit to Patent Office of the People's Republic of China divides an application.

Technical field

The present invention relates to radio communications system.Be particularly related to the radio telecommunication terminal of the user's use that is connected on the radio communications set, when carrying out access on the internet, radio communications set uses radio communications system, radio communications set and the radio telecommunication terminal of public's radio circuit.

In addition, radio communications set and the radio terminal equipment that the invention still further relates to the authentication method of the device that is used for the specific communications object and utilize this method.

The invention still further relates to and utilize the radio communication function construct on public transportation vehicles such as bus or electric car, provide the navigation information (to call the information of getting off in the following text) of getting off etc. to the passenger, the operation management system that carries out the operational management of vehicle.

Background technology

In recent years, mobile phone or radio LAN range radio communication systems such as (Local Area Network local area network (LAN)s) obtains generally popularizing, because accessibility is good, and is widely used.For example, can simply construct LAN in the family, carry out daily:, utilize mobile phone to receive homepage on Email or the reading the Internet on the ground of going out with radio LAN.

In addition, studying radio LAN service in the vehicle that bus or electric car geometric ratio long period ride.At the radio communications system that is used for realizing this radio LAN, in the vehicle that moves, be provided as the radio communications set that the radio LAN of radio base station uses and construct radio LAN.Have again, this radio communications set, the access method as outside with the Internet etc. has: be used for connecting the function as the mobile telephone network of public's radio circuit.Thus, the terminals such as the employed radio LAN of users such as notebook personal computer in the moving vehicle by radio communications set and public's radio circuit, can connect on the internet.

As this public's radio circuit, can enumerate cellular system, PHS system etc., particularly as the high-speed radio electrical communication system, know: the system that utilizes cdma 20001xEV-DO mode.For example, open the 2002-300644 communique with reference to the spy.

, in the radio LAN of above-mentioned conduct radio communications system in the past, there is following problem.

To outsides (server) such as the WEB on the Internet (World Wide Web (WWW)) servers when access is arranged, carry out being connected between radio communications set and the public's radio circuit from wireless LAN terminal as required.Therefore, if the wireless LAN terminal request is carried out access to a certain homepage, then radio communications set at first begins and being connected of public's radio circuit, and finishes after this connection beginning access purpose homepage.Yet, during from moving vehicle connection public correspondence network, because radio transmits the reason of environmental turbulence, so on it connects, need long-time.Particularly at the public's radio circuit that uses PPP (Pointto Point Protocol point-to-point protocol), PHS (PersonalHandy-phone System people's mobile telephone system) or be called the code division multiple access connection (CDMA of " cdma 20001xEV-DO " for example; The connection of Code Division Multiple Access code division multiple access) particularly showing in the network of mode.

Therefore, finishing before public's radio circuit connects, take place earlier: overtime when coming the access homepage with the application program (browsing) of wireless LAN terminal one side, in fact, although the access to homepage is possible, on wireless LAN terminal, demonstrate information from access to the purpose homepage that to carry out.This is concerning the user, and not knowing to connect public's radio circuit still needs the time or really can't carry out access to the purpose homepage, thereby gives the user uneasy sense, and is very inconvenient.And, in wireless LAN terminal one side, show and can not carry out access to homepage although the time of application program is overtime, exist radio communications set to carry out access, thereby produce the problem of waste to public's radio circuit.

In addition, in the radio LAN as above-mentioned radio communications system in the past, also there are the following problems.

When the radio communications set in moving vehicle connects public's radio circuit, because the position difference of vehicle, and the radio state between public's radio circuit is in variation, so not necessarily successfully connect.In addition, the employed public's radio circuit of PPP (Point to Point Protocol point-to-point protocol), for example PHS (System people's mobile telephone system of Personal Handy-phone) or the code division multiple access that is called " cdma 20001xEV-DO " connect (CDMA; Code Division Multiple Access code division multiple access connects) in the network of mode, connect the required time according to radio state or radio user number and change to some extent.Yet, the user in the moving vehicle do not know and public's radio circuit between radio state or public's radio circuit user's number.Therefore, the user at first will attempt the Internet connection via public's radio circuit, and still, radio communications set is for example outside the public's radio circuit service circle time, and user's radio telecommunication terminal can not connect on the internet.In addition, when radio communications set tanglewracked in public's radio circuit business, even user's radio telecommunication terminal carries out access to the Internet, its response was also very slow.

Promptly, because the user does not know radio state between radio communications set and the public's radio circuit or user's number of public's radio circuit, so unclearly why can not connect the Internet or why access responds also bad problems such as reason even exist.

, in above-mentioned radio communications system in the past, there is following problem.

According to request from wireless LAN terminal, when the public's radio circuit in moving vehicle connects the Internet, though utilize mobile telephone network as public's radio circuit, but the communication speed of mobile telephone network and radio LAN etc. are relatively, abundant inadequately, be difficult so happy the Internet access environment is provided.In addition, along with the difference of vehicle location, and the deterioration of the radio state between the mobile telephone network, or the mobile phone user of utilization and the outside same base of moving vehicle is for a long time, and it is slower that communication speed becomes.

In recent years, as follow-on high-speed radio telecommunication mode, developing cdma 20001x-EV DO (to call " EV-DO " in the following text) mode.So-called EV-DO mode is an expansion cdmaOne mode, and will be corresponding to cdma 20001x mode characterization in data communication of third generation mode, makes the mode of transfer rate high speed.Here, " EV " means Evolutin (improvement), and " DO " means Data Only (data are unique).

In the EV-DO mode, the formation of the radio interface of the uplink from the radio telecommunication terminal to the base station and cdma 20001x mode are almost same.As for the formation of the radio interface of the downgoing line from the base station to the radio telecommunication terminal, the band field width that is defined as 1.23MHz is identical with the cdma20001x mode, and still, modulation system, multipleization mode very much not are same as cdma 20001x mode.Utilize the modulation system of QPSK, HPSK in cdma 20001x mode, relative therewith, in the EV-DO mode, QPSK, 8-PSK, 16QAM are switched according to the receiving state signal of the downgoing line of radio telecommunication terminal.Its result when receiving state signal is good, uses the low and transfer rate at a high speed of anti-mistake, and when receiving state signal is bad, though use the high transfer rate of the anti-mistake of low speed.

In addition, carry out simultaneously from a base station to the multipleization method of the communication of a plurality of radio telecommunication terminals being used for, be not to use that employed code division multiple access connects (CDMA in cdmaOne mode or the cdma 20001x mode; Code Division Multiple Access), but it was unit sliced time with 1/600 second, in its time, only communicate with a radio telecommunication terminal, and, use: the radio telecommunication terminal that will become communication object switches by each chronomere, thereby carries out being connected (TDMA with the time division multiple access of the communication of a plurality of radio telecommunication terminals; TimeDivision Multiple Access).

As accepting state from the downgoing line of the base station that becomes communication object, radio telecommunication terminal is measured the carrier wave interference Bob (to call CIR:Carrier to Interferencepower Ratio carrier-in-interference power coefficient in the following text) of pilot signal (pilot), from the accepting state of the next time of reception of its change prediction, will expect then " fixed error rate or high transmission speed that can received signal below it " notify to the base station as data rate control bit (to call " DRC:Date Rate Control bit " in the following text).Here, though fixed error rate exist with ... system design, be generally about 1%.The base station receives the DRC from a plurality of radio telecommunication terminals, scheduler function in the decision base station is in each time-division unit, which communicate with radio telecommunication terminal, but, with the communicating by letter of each radio telecommunication terminal in, basically based on the DRC of radio telecommunication terminal, use high as far as possible transfer rate.

According to above-mentioned formation, the EV-DO mode is in downgoing line, and the transfer rate of the maximum 2.4Mbps in every district (Megabit per second) becomes possibility.But this transfer rate is at a frequency band and usually has in a plurality of sections one, the total of the data traffic between a plurality of radio telecommunication terminal that the base station connected, if use a plurality of frequency bands, then transfer rate also increases.For example, open the 2002-300644 communique with reference to the spy.

Different with such EV-DO mode, may use the field in order to enlarge as the LAN of the network of company, family, also develop radio LAN, especially come standardized radio LAN to have the ability of the communication zone of the transfer rate of maximum 11Mbps and radius 50～100m with IEEE802.11b.Along with popularizing of the ADSL of cheapization of the high speed of transfer rate, access point, portable terminal or family, generally popularized.In addition, as the utilization outside the room, begun the on-the-spot service of street corner in extremely restricted place.Be that radio LAN and EV-DO mode compare,, can provide transfer rate more at a high speed though the coverage is narrow.

On the other hand, also research: the interior radio LAN service of vehicle that bus, electric car geometric ratio long period ride, by in moving vehicle, being provided with: communicator with communication agency of the communication agency of radio LAN and mobile phone, utilize radio LAN to connect between the notebook PC in the vehicle etc., utilize mobile telephone network to be connected on the outer the Internet of vehicle, thereby can the notebook PC in vehicle connect the Internet outside the vehicle.When using radio LAN in vehicle, service provides a side to connect radio for fear of irrelevant people, needs the authentication formality, and, be leaked to other user because of carelessness for fear of the information that the user sent, be necessary to implement encipherment.Usually, in radio LAN, the method for fear of other user is connected access point absent-mindedly has: key (WAP), MAC Address registration etc.During radio LAN service in vehicle etc., because the person does not distribute radio LAN card etc. to utilizing the object, so can not carry out the user's that MAC Address registers qualification.Therefore, adopt:, and be set in method on the terminal that the user utilizes in advance to the corresponding key of user notification access point.In addition, when serving this, when user radio has been electrically connected the radio relay device, show specific inlet, can utilize the authentification of user of user name, password as chargeable service.

The relative access point of the encipherment of utilizing key of above-mentioned radio LAN has only one.Therefore, be connected between the user on the access point, use identical key.Between the user who utilizes identical access point, the confidentiality boundary is low, the danger that just has the information in radio communication be read.In order to improve fail safe, be necessary each user is set different encrypted messages, authentication information.If the utilization of corresponding common WEP key or authentication formality, then at least when initial the connection, one side is seen the paper that records pre-assigned encrypted message, authentication information, see that on one side terminal picture, user just can utilize input mechanism such as keyboard to input encrypted message or authenticate authentication informations such as user name in the formality, password.Usually, during moving vehicles such as bus, electric car, the people takes with the distance that shoulder contacts with each other.In such environment, the above-mentioned paper content that records encrypted message, authentication information is seen by the bystander easily, can not guarantee confidentiality, and the user is in bus that rocks or electric car, and correctly importing the bad key of remembeing is an operation of trouble.

In recent years, mobile phone was developing to broadband direction, and in third generation mobile, the communication speed of down direction maximum realizes 2.4[Mbps] (for example, opening the 2002-300644 communique) with reference to the spy.In addition, in commercial firm, family,,, generally can construct radio LAN because its ease of use is good by among the LAN of networking.Especially, be suitable for the follow-on radio LAN of IEEE802.11b specification, along with popularizing of the ADSL of cheapization, the particularly general family of high speed, access point or the portable terminal of in recent years transfer rate, beginning is popularized widely.And, utilize outside the room as the mobile phone that has used these radio LAN, begin the scene service (to call the on-the-spot service of street corner in the following text) of street corner etc. gradually.

In addition, radio LAN will be converted to wireless mode with the mode between the wire cable connecting terminal in the past, and is high by the compatibility between wired LAN always.In this background, the radio LAN that becomes main flow now is suitable for IEEE802.11b, and its transfer rate maximum is brought up to 11[Mbps].In addition, because the zone radius of the access point of this radio LAN is 50～100[m] about narrow scope, so use the on-the-spot service of street corner of the mobile phone of these radio LAN to be defined as the service that the utmost point is limited to the place.

On the other hand, though each year of the transfer rate of mobile phone continue high speed to the broadband,, compare its transfer rate with radio LAN still slow.Yet the service area radius of an access point only is 2[km] left and right sides is wide.

In addition, in radio LAN, popularize: and mobile phone is same, and a plurality of access points are set, even go over these access points, mobile node does not change the IP address yet, thus the mobile IP technology of energy consecutive access.This mobile IP has: chain the local agent as router (Home Agent) with interface and chain the external agent as router (Foreign Agent) with interface at the moving target of mobile node at the homepage of mobile node; And mobile node obtains concern address (Care of address) that moving target chains afterwards, with this pay close attention to address as the concern address registration of moving target in local agent.On the other hand, local agent will be by carrying out capsuleization (kapsel) afterwards to the packets of information that mobile agent sends signal, be transferred to and pay close attention to the address, thereby the IP address of not changing mobile node just can be transferred to packets of information the mobile node that moving target chains existence.

In addition, at ITS (the IntelligentTransport System (intelligent transportation system): the freeway traffic system) that merges car navigation system and wide area traffic control system, the radio communicationization of planning car navigation system, by connecting mobile phone, can send and receive e-mail or the access the Internet.And, cheapization along with hard disk, than CD (Compact Disk CD) or DVD (Digital Versatile Disk DVD) access possibility more at a high speed, the road information of car navigation system is transferred to the form that is stored in the HDD (Hard Disk Drive hard disk drive) from DVD.Also have,, also realize utilizing wireless system gradually as the update method of road information.

Yet, utilize the passenger that utilizes of radio LAN service in the vehicle, to moving vehicles such as bus or electric cars,, can not in real time, know this whether around operation information of operation even can confirm the timetable that is predetermined.In addition, taking place to utilize the passenger not grasp in real time when late owing to traffic accident: to the frequency at desired station or station, arrive at a station and cause what kind of influence constantly.

In addition, in embodiments of the present invention,, be that example is illustrated with the bus as moving vehicle, still, can certainly be applied in other the vehicle such as electric car.And, in embodiments of the present invention, describe as the public correspondence net of the moving vehicle outside 1x EV-DO that gives an example, still, also can be other radio communication mechanism such as PHS.

Below, illustrate: vehicles such as bus get to the station or by the time, infer to get to the station constantly or the specific embodiment of frequency.At first, upload the information such as due in, frequency at station to administrative center from each vehicle.At this moment, additional weather forecast etc. is uploaded to administrative center.

Thus, administrative center infers that according to the arrive at a station moment, the frequency of each vehicle each vehicle arrives the moment at next station.And administrative center calculates AT STATION down time according to the time information of obtaining from each vehicle, with these temporal informations, corresponding to each station, constantly, weather and adding up.At this moment, administrative center according to the elder generation of the same routes of the travelling running time by vehicle, estimates to arrive the moment at next station.In addition, the vehicle that stops AT STATION is judged as the deduction that different routes carry out due in the vehicle that does not stop.

Figure 36 is in an embodiment of the present invention, when vehicle does not stop AT STATION, carries out the schematic diagram that due in is inferred.In addition, Figure 37 is in an embodiment of the present invention, the ridership at consideration station or weather etc., and carry out the schematic diagram that due in is inferred.And Figure 38 is in an embodiment of the present invention, tries to achieve the schematic diagram constantly that gets to the station with computational methods.

In Figure 36, vehicle 2 is by station S, and the moment YY2 (S+1) of the S+1 that gets to the station is according to estimating by the vehicle 0 and the vehicle 1 of same routes earlier.In addition, when vehicle 2 stopped AT STATION, vehicle 0 and vehicle 1 utilized the data of the vehicle that is parked in the station too.In addition, when estimating to arrive the time of station, distant place S+n, be to utilize the statistical value of databases storage to carry out the down time from station S to each station that exists the S+n of station (boarding time).And, because the ridership at consideration station shown in Figure 37, constantly, the statistical value of weather etc. is stored in the database, so, obtain corresponding statistical value from database, can obtain the due in or the frequency at each station.

Below, in conjunction with Figure 38, utilize Calculation Method to obtain and get to the station constantly.That is, get to the station moment of S+2 is shown below and obtains.

[due in of station S+2]=[due in of station S+1] (T1 (S+1))+[down time of station S+1] (W1 (S+1))+[running time] ((S1 (S+2)) from station S+1 to station S+2.

Figure 39 is in an embodiment of the present invention, when considering near the traffic conditions the crossroad, estimates the schematic diagram of due in.As shown in figure 39, at the parting of the ways near, take place: crowded with always the crossroad, by just eliminating crowded road conditions or in contrast to its condition of road surface in the crossroad.Therefore, in motion in the deduction between, as fulcrum, be divided into forward and backwardly the crossroad, estimate.In addition, for the deduction of the due in of considering such condition of road surface, each vehicle is necessary the moment that enters the moment of crossroad or come out from the crossroad is uploaded to data center.

And, when having accident to take place,, the accident occurrence positions of gps coordinate is uploaded to data center by the driver of the vehicle of having discerned this accident, append owing to after the item of the estimation due in overtime of the follow-up vehicle that accident causes, carry out correcting process.

In addition, in the above description, as the moment of uploading to data center, the example for station and crossroad due in, frequency still, is not limited to these.In addition, consider, preferably, carry out uploading of data according to each interval with being divided into thinner interval between the station from the precision that improves due in or frequency estimated result.Like this, even distance local or because accident congested and need the long time than usual also can more correctly be estimated due between the station.

Figure 40 is in an embodiment of the present invention, shows to get to the station at outside vehicle and estimates the schematic diagram of state constantly.As shown in figure 40, estimate that by showing at outside vehicle to get to the station constantly, the passenger just can know the general time of advent before by bus.And, also can provide same time information from the server of the Internet.

As above illustrated, operation management system of the present invention is to construct radio LAN in the car of bus or electric car etc., by this radio LAN, provides the railway station of getting off or the relevant information at station to the mobile telephone terminal that the passenger held in the car.For example, the information as providing to mobile telephone terminal has: the station of getting off or the notice in railway station, the notice of the time of passing through by station or railway station etc.In addition, when being train,, just know automatically that the stop or the moment also are fine if portable terminal reads in the appointment certificate.

When portable terminal was got off notice, the passenger in utilized the portable terminal registration to want the station of getting off in advance by bus.Like this, master computer is to passenger's the portable terminal of registration, in by the appropriate time behind the previous station of wanting to get off, and the notice of getting off.At this moment, the location determination of the moving vehicle that master computer carried out is ideal in conjunction with GPS or map, and still, the information the when crew gets off the audiotape of guide according to manual broadcast is judged also and is fine.

In addition, master computer has the situation that is located at the situation in the moving vehicle and is arranged on ground command centre, still, the difference of informing function can not take place.Have again, also can be only from command centre's receiving position information on the ground, and in moving vehicle, handle the identification of registered portable terminal.That is, the role-sharing of operation management system can be considered the whole bag of tricks.In other words, operation management system of the present invention can be by the master computer that is provided with on the ground, be loaded in the branch computer in the moving vehicle and the portable terminal that the passenger held that rides in the moving vehicle constitutes, and still, function sharing separately is not specific.

In addition, as with the auto-navigation system identical functions, can judge the current position of moving vehicle with mainframe computer system on the ground, utilize current position data and actual speed of service data, come the time of passing through or required time to portable terminal place that notice is decided.For example,, utilize the data such as required time of previous bus, calculate passing through the time of next station, then reflect the road congestion condition, can correctly predict passing through the time by the station if in the time will passing through the station.
