In a particular configuration, changes of the indication of the location of the portable device are used to update positional information, such as positional information obtained from a GPS receiver.
Description
Technical field
The present invention relates to radio communication and location (location) data that provide about mobile comm unit are provided, for example emergency service number is called out the location.
Background technology
Wireless transmission/receive unit (WTRU) but comprise is not limited to the equipment that can work of subscriber equipment, mobile radio station, fixing or moving user unit, beep-pager or any other type in wireless environment.When mentioning hereinafter, the base station includes, but are not limited to the interface equipment in the wireless environment of node (Node) B, site controller, access point or any other type.The wireless environment of these exemplary types includes, but are not limited to WLAN (WLAN) and public land mobile net network.In the context of the present invention, the portable nature of some WTRU is very important.Portable WTRU comprises mobile phone, has the mobile phone of data function, radio modem and other equipment.
For example various communication services are provided on the cell phone network at wireless network.In addition, it is just more and more universal to have a wireless network of multiple RF service and a plurality of networks.Many networks service of one type comprises cellular basestation that voice communication is optimized and to " focus (hot pot) " access point of high capacity data transmission optimization.In some embodiment of these systems, " focus " access point with provide the wireless network of voice communication integrated.
Cordless communication network is controlled or is controlled by bigger network for its wave point usually.Under the situation of cellular network, the control of wave point and cellular network controlled function are integrated.The cellular network controlled function directly realizes by the cellular network controller or is realized by local unit by the cellular network controller.Described local unit can be base station or pilot controller (subsidiarycontroller) Node B for example.On the contrary, access point (AP) is for its wave point and local control.
Under the situation of Universal Mobile Telecommunications System (UMTS), the control of wave point and radio network controller function are integrated.The radio network controller function directly realizes by radio network controller (RNC) or by RNC by for example Node B realization of local unit.In these are provided with, switch or provide switching although can between RNC and AP, communicate and provide from AP to AP, access point (AP) is for its wave point and local control.
Can be from a plurality of AP of single controller module controls; Yet this control has produced air interface, and the effect of this air interface is controlled at AP as communication.Because wireless communication system comprises a plurality of assemblies, some cellular network controller function can realize by AP, and some function that inserts by AP usually can insert by cellular communications networks.
Under normal conditions, cordless communication network directly provides communication by the network by operator (carrier) control.AP provides by operator or the direct communication that is connected with individual networks.For example, AP can provide and being connected of TCP/IP Internet connection.Replacedly, AP can be by setting up the TCP/IP Internet connection via the connection of operator's route.Yet should be appreciated that cellular communication can carry out and tcp/ip communication can be undertaken by cellular network by AP on WLAN (WLAN).
The locator data that WTRU outside the locator data that provides by determining localized wireless receiving zone is provided is very useful from a lot of aspects, emergency services for example is provided and provides consumer's direction auxiliary.The emergency service call person dials the emergency alarm number, and emergency services is sent the caller location immediately thus.This be by use emergency service number or general emergency number for example " 999 " (UK), " 911 " (North America), " 102 " (Europe) or the like and insert.
A lot of EC have the characteristic that is called " source point mark ".Caller's telephone number is by Network Transmission, and is arranged in telephone network supplier's database with this telephone number corresponding address.By using numerical map and mapping application program, the position of this address (position) can show on map when calling out arrival immediately.
By land under the situation of circuit, caller's location is provided by telephone bill data etc. usually, is called automatic number identification (ANI) in North America SS7 system.The modification of ANI promptly so-called " strengthen 911 " is implemented in the North America, but these services remain based on the fixed-line subscriber location.
Under the situation of mobile phone service, physical positioning is not intrinsic in the Connection Service.Mobile phone is usually by region code and prefix (if having used ANI) location, perhaps by the fixed base stations location of handling specific call.Automatically the target of positioning mark (ALI) is by based on network positioning mark or by the physical location of mobile phone is provided based on the geo-location (geolocation) of WTRU.
Exist ALI can't accurately determine the situation of the location of WTRU, especially obvious when the WTRU that supports GPS can't obtain gps satellite.For instance, the metallization of building can produce faraday's obturator that GPS receives.Therefore, although " strengthening 911 " required part and whole ALI abilities, the ALI data may be unavailable.Based on the object of the invention, " GPS " is used to describe GPS and other wide-area wireless geo-positioning systems, for example GLONASS, Omega, Loran or the like.
In the U.S., " strengthening 911 " legislation is based on governmental mandates to a great extent, wherein requires all mobile phones to have stationkeeping ability in calendar year 2001 end.When drafting, political suggestion thinks that required what do is exactly the accurate location that starting hand-set and GPS function can provide the user to the cellphone subscriber.The compatible rate of the mobile phone of new production is very low, and part is because GPS location technology expensive and because to receive enough gps signals by mobile phone very difficult, particularly in obturator in.
The GPS locating information is very accurate when the equipment of supporting GPS gets access to the satellite of sufficient amount, is common situation but satellite covers omission.This situation is not especially obvious when being positioned to receive the equipment of the support mobile GPS of gps signal specially in use.Greatly reduce the effectiveness of GPS function like this.Another problem of using the GPS location is that some WTRU is fabricated to usually and does not possess the GPS function.For instance, the WTRU that is used to transmit data rather than voice can be designed to not have geographic positioning functionality usually.
The availability of " focus " access point and other various communication networks is consistent with the environment that is difficult to acquisition ALI data usually.For instance, " focus " access point can be used the user of building interior usually.In another example, the user can confirm that near the general location the base station still needs communicate by diversity network (diverse network).
" focus " for example can be the access point that meets IEEE 802.11 standards or similar communication standard, can think WLAN or 802.11 access points.802.11 access point provides the major control of air interface, and is totally independent of air interface and sets up and being connected of external communication network.Under normal conditions, external communication network is Internet connection or is used to insert Internet connection.Although can for example by another access point, set up Internet connection by the wireless connections of access point, the outside connection finally is based upon outside the air interface of access point.Therefore, different with cell phone network, 802.11 connections are not connected to each other with the cellular network controller for the purpose of setting up wireless connections usually.Under this meaning, the wireless connections that arrive access point from WTRU are the networks by the access point outside.
In the configuration of some proposition, the ALI data combine with " focus " location database to provide information about service availability from " focus " access point to WTRU.In case identified candidate " focus ", then WTRU can determine that it can or can not connect with this " focus " access point.
Service based on the location exists for the interests that satisfy the wireless user.A kind of service like this provides the driving direction, and this can use with mobile phone is collaborative.Common, the user of these services need provide the information of " source point (from) " with the form when prelocalization before the direction that obtains " arriving (to) " expectation destination.Except requiring the additional step of user interactions, the user also can get lost usually, can not discern user's certain position at least to a certain extent.The local position information except that the positional information that honeycomb and honeycomb sector (sector) provide that is provided can allow these directional informations services to determine " source point " information and do not need the user to import.
Propose at present and realized that multiple positioning service is to provide the accurate information of sign mobile phone location.These comprise the sign of fixed base stations, honeycomb GPS and network TDOA, wherein the propagation time that arrives the some Location Measurement Units that are installed in the base station from mobile phone are compared.Location Measurement Unit is a wireless receiver, and detected signal is carried out the high speed crosscorrelation for it and common support is installed in the place, base station.
Based on standardization in the at present a lot of air interfaces of the service of location and begin to become the part of wireless experience.Current system uses from the time delay information of a plurality of base stations usually and carries out triangulation and locate with estimating user.If there are a plurality of overlapping systems, for example common and WLAN and the overlapping situation of UMTS, the location estimation of himself is finished in each system's expection.Therefore, need improved geographical positioning service.
Summary of the invention
According to the present invention, the data that connect from a plurality of wireless networks are combined so that precision higher when determining the WTRU location to be provided.In customized configuration, cellular radio and dissimilar Local wireless network cooperations produce the locator data of WTRU.
According to a particular embodiment of the invention, enlarge by using the information of obtaining from the diversity network for the locating information in the wireless network of the location of identifying user WTRU.
In yet another embodiment of the present invention, be used to be independent of the diversity network obtain the user the WTRU location data for example gps data combine with the data that location by use diversity network obtains.Described diversity network can be used for inferior locator data is proofreaied and correct adjustment and determined that the location of portable set changes.Like this by the continuity of the locating information of user WTRU is provided in conjunction with main locator data and time locator data.

Embodiment
The invention provides with detection and localization with based on the service extension of locating and arrive multi-network environment, in this multi-network environment, thereby owing to can use new information to determine the user location more exactly, and locating information between a plurality of networks, share so that with in auxiliary another network of the locating information of obtaining in one network based on the service of locating.
Detection and localization and positioning service only are defined in single network and the single-unit situation traditionally to determine customer location.Thereby the present invention allows by using the user's location estimation from a plurality of networks to obtain better user's location estimation together, and shares locating information in one network to support the service based on the location in another network.
The present invention makes location estimation more accurate by using the location estimation from a plurality of networks, thereby has increased estimated accuracy.Owing under many network condition, have more available information, therefore can obtain more accurately and estimate.For example, the location estimation during WLAN covers can be as accurate as some feet (a meter), and the precision among the UMTS only is accurate to some rice.If two networks are shared these information, then can be as accurate as some feet know in the UMTS system the user wherein.
Another advantage of the present invention is that the locating information from a network can be sent to another network and support service based on the location.
Fig. 1 is the diagram of the realization of demonstration illustrated embodiments of the invention.Wireless network 11 comprises cellular network controller 12 and a plurality of base station 13,16.WTRU 21 can communicate with base station 14 for example shown in Figure 1, one or more base station.Normally, except between transfer period or under other particular cases, communication is kept by single base station by WTRU 21.
Local " focus " access point 27,28 also can be set up the wireless connections with user WTRU 21." focus " access point 27,28 is an any wireless network services, and its scope is more limited than the scope that cellular basestation provided usually, but its at High Data Rate is provided optimised mistake.In some cases, " focus " access point 27,28 be integrated in the cellular network or can with cellular network communication.
Receive from the signal of user WTRU 21 base station 13,16, and receive the value of expression positional information by cognitive (cognizant).Except the signal that receives from the base station 14 of distributing to user WTRU 21, one or more base station 13,16 may receive the WTRU21 of enough signal messages with identifying user.These information combine with information from focus 27,28 in two ways.The first, focus 27,28 can provide the indication that closes on of WTRU 21 by signal strength signal intensity.This method is the most effective for very localized " focus ", for example can offer the enterprise customer in enterprise.This information is by the indication of cellular network controller 12 as the possible position of WTRU 21.WTRU 21 be assumed that be in by " focus " access point 27 measured signal strengths consistent location.
The second, " focus " access point 27,28 can provide some positioning service, and position data is provided thus.The most effective under the situation of this method focus of user at extensive region, block, for example some cities.A kind of method that obtains locating information by the focus access point is to calculate the relative delay between the signal that institute sends and received and infer the distance of signal propagation thus.Provided the indication of the distance of access point and WTRU like this.
A kind of method in back is in conjunction with the positioning service of some networks of great use.Therefore, although emulative network can or can not provide the connection that arrives WTRU in its overlay area, these networks can provide locator data to be used for communication service to the employed network of WTRU.
In described situation, WTRU 21 is being designated WTRU 21 on the degree required in the overlay area of base station 14 or sub-district by base station 14 communications.And " focus " access point 27 also communicates with WTRU21 in that WTRU 21 is designated on the degree required in the overlay area of " focus " access point 27.For cellular network controller and the network relevant with " focus " access point 27, these information are enough to obviously determine that WTRU 21 is in each overlay area.In some cases, base station 14 also can obtain the locating information about WTRU 21.
The geo-location data that provide by WTRU 21 can be provided locating information.Determine what geo-location was normally undertaken by the gps receiver among the use WTRU 21 by WTRU 21, this will be described below.Base station 14 can use location Calculation for example TDOA calculates or other location technologies to determine the location of WTRU 21.If the geo-location data that provide by WTRU 21 have been provided in base station 14, then these data are considered to need further to calculate accurately and not usually.Yet in fact, the geo-location data from WTRU are generally unavailable or interruption.Particularly, do not have the clearly RF observation of some satellites, data are disabled.Common construction material and other environmental factors can intercept satellite-signal, and do not have clearly RF observation.Based on this reason, base station 14 can enlarge gps data by other locator datas.
According to the present invention, the cellular network controller related with master network is direct and obtain locator data from the diversity network indirectly.Data from the diversity network combine with the data of obtaining from master network.Then the cellular network controller in conjunction with described data to obtain the location estimation of optimizing from the data of master network and diversity network by comprising simultaneously.
The information about locator data from the diversity network may perhaps can be stored in the database 29 by the cellular network controller directly from the diversity network.In a lot of situations, database 29 comprises about the general information as the location of one or more " focus " of the receiving area of diversity network.These data can be by using " focus " location catalogue, by inquiring about " focus " access point or by obtaining about the conforming historical data between the known locations of the WTRU that is connected with access point.
In the example depicted in fig. 1, master network comprises base station 13,16, thus can by from the base station 14 information of obtaining obtain described data.The diversity network can comprise " focus " 27,28, and the cellular network controller will be from the base station 14 information of obtaining combine with information from " focus " access point 27.
Wireless network can use the location from the information direct search emergency service number caller in all these sources then, perhaps replacedly, and for additive method provides additional locating information (for example TDOA).
In a lot of situations,, perhaps only has general address date for the diversity network of " focus " service can not have data available about " focus " access point geo-location.Can discern on the degree of " focus " access point by the known locations of WTRU at cellular network controller 12, cellular network controller 12 can comprise described " focus " location to enlarge described database.
Fig. 2 is for showing the diagram according to the wireless network 41 of modification of the present invention.As shown in Figure 2, GPS or other position datas strengthen by the locator data of being obtained by the combination of base station 43,46 and diversity network 47,48.User WTRU 51 has GPS or other location positioning circuit 52.If user WTRU 51 can obtain enough satellites, then user WTRU 51 can report accurately that its position is to cellular network controller 12.The gps data of satellite 53 expression is considered to than the signal that will receive from user WTRU 51 by diversity network 47,48 or more accurate by compare with the information that receives from diversity network 47,48 data that obtain of the signal that base station 13,16 receives from user WTRU 51.
Can predict, although it is gps data is more accurate, but usually unavailable.According to one aspect of the invention, when gps data is unavailable, by being used to upgrade gps data from the signal of user WTRU 51 information of obtaining of comparing with the signal that receives by diversity network 47,48.In a particular embodiment, by will be from the signal of user WTRU 51 position change that the information obtained is used to indicate WTRU 51 of comparing with the signal that receives by diversity network 47,48, thereby mainly gps data is made amendment according to the change that senses, rather than produce the new positional information that is independent of gps data by regulating gps data.
The information about locator data from the diversity network strengthens by using the gps data from WTRU, because the data of locating about " focus " are not always available for master network under many circumstances.Receive under the available situation being connected to GPS during " focus " access point, be connected conforming data about gps data with " focus " and can be stored in the database 29.Like this, after this, the connection with " focus " access point can be assumed to the gps data of previous report consistent.This is very important, because under many circumstances, and most independent and the availabilities that can not comprise gps data that are connected given " focus ".
Fig. 3 is for showing the flow process Figure 100 according to location estimation of the present invention.Obtain WTRU (step 101) and correspondingly by master network or diversity network, the network that is obtaining is attempted the location (step 102) of sign WTRU.Positioning mark (step 102) can begin when getting access to WTRU or be deferred to up to having set up further communication linkage.
Determine whether WTRU can provide positional information usually based on GPS geo-location (step 103).If the GPS positional information can be used, then be used (step 104).The determining and use (step 103 and 104) only to provide by way of example of gps data, and can adopt determining of any locator data to predetermined accuracy.
If the GPS positional information is unavailable, and is determined as step 103, determine that then previous GPS indicates whether that available (step 110) and previous GPS indicate whether effectively (step 121).Validity depends on time and motion, and the consistency represented of the local position of gps data and WTRU.
If there is not available previous effective GPS indication, the data (step 112) that provide by master network then is provided and carried out location estimation (step 111) from the data (step 113) that the diversity network obtains.This can be independent of the diversity network and by using the diversity network to carry out by master network.Under (step 113) situation that data are obtained from the diversity network, the database data that is provided by master network is used to provide additional information.Suppose that master network attempts obtaining locator data, then WTRU is assigned to specific base stations, and master network obtains available data from this base station.Except the base station that is assigned described WTRU, network can also use the data from neighbor base station usually.The ability that is resolved to master network from the data of the base station of master network can be used in the degree of determining the WTRU location.In addition, data are obtained from the diversity network.Described data can be determined for the position that is considered to have specific precision.Combine with data to obtain WTRU location estimation more accurately from the data of diversity network from master network.Described diversity network data can be obtained from a plurality of diversity networks.
Can change between the data about certain position to the particular access point of diversity network at the general information that the diversity network can be identified as WTRU in its overlay area from the data of diversity network.The ability that the possible position that precision that then must specified data and data limit are undertaken by master network is estimated.In one embodiment, the data self from the diversity network are self limit.Master network can combine described data by using database with the data of directly obtaining by master network then.For example, if the diversity network has specific geographical coverage area, can identify WTRU in this zone, then the data from the diversity network are that WTRU is in described geographic area.On the other hand, the diversity network can provide certain location to estimate.Described location estimation can comprise that accuracy data or accuracy data can obtain separately.Data from the diversity network can be compared with the data that described data are related with further data.Further related between definite of the location of geo-location data, the location determination (position fix) that provides with signal value and the pre-definite of the precision that may locate the locator data of carrying out related database, obtaining by the diversity network and by the diversity network or numerical value and known precision can be provided data.
Under ambiguous situation, the problem of design alternative is which data is accepted as truly.Can obtain some location verification, for example by obtaining GPS location registration (reading) and the GPS registration being compared with described estimation.These checkings can be used to provide the correction to following location estimation.
If previous GPS indication is confirmed as effectively (step 121), then carry out estimation (step 123) to position change.This can carry out by using the diversity network to be independent of described diversity network by master network, perhaps by using the data combination from master network to carry out from the master network of the data of diversity network.The estimation of position change is used to revise the GPS position of being reported then, thereby the position of being reported is based on (step 126) of GPS position, is not separately by the independent location estimation that produces.
The validity that previous GPS estimates can be revised by the availability from the speed sense data of WTRU, as shown in phantom in FIG..Be considered to than the signal change that receives by the diversity network when determining the validity of gps data, consider described rate information on the reliable more degree at rate information.
If WTRU provides navigation data based on GPS for the user, then network can determine to upgrade gps data for the location according to network.Under the situation that gps data may be interrupted, provide continuity like this based on the navigation data of GPS for the user.
Can be according to allowing the diversity network when gps data is unavailable, to enlarge or replacing the mode of gps data and gps data is combined with data from master network and diversity network.Gps data receives from user WTRU between the gps data available life, and the main locator data about user WTRU location is provided thus.During gps data is unavailable, use locator data, thereby the inferior locator data about user WTRU location is provided from the diversity network.Allow like this when using diversity network, master network or diversity network and combining of master network proofreaied and correct adjustment, gps data to be used as main locator data.And allow by will combine the successional GPS that uses simultaneously of the locating information that user WTRU is provided with inferior locator data from the locator data of GPS.
Foregoing description comprises use master network and diversity network.The diversity network can comprise by " focus " access point of master network management or be independent of " focus " access point or other access points that master network is managed.The diversity network can also be different network services, for example analog network or permission user's " roaming " network.Positioning service can be carried out by diversity network and master network, and particularly takes place in the user needs the situation of emergency services in " roaming " pattern.Under the situation that positioning service is carried out by the diversity network, the above-mentioned function relevant with master network can be carried out by the diversity network, and the above-mentioned function relevant with the diversity network carried out by master network or other diversity networks.
Conceptive, more than description comprises the wireless network and the local control network network that comprise one or more access point (AP) of use by the control of cellular network controller.AP can or be independent of the cellular network controller management by the cellular network controller management, but works as the independent groups of one or more wave point.Thereby from the combined precision of determining to provide raising for the WTRU position of the data of described network.Further position data for example gps data can be used to be independent of described network and obtain the position of user WTRU and combine with data of obtaining by the location of using the transceiver related and the locating information obtained from the wireless network of controlling by the cellular network controller with the local control network network.Like this by will be for example from combine with the inferior locator data continuity of locating information that user WTRU is provided of the main locator data of GPS.
