Support in function in positioning, location server 160 can using the Given information of mobile device 105 come more effectively with/ Or efficiently support positioning.For example, location server 160 can recognize that by the localization method of mobile device 105 most preferably support With certain position relevant information (such as particular measurement or specific assistance data), and/or identify some measure (such as RSSI, RTT Deng) error and/or calibration parameter possible source.Location server be also with mobile device known fault or limit with Avoid the mistake of mobile device or inaccurate positioning.In some cases, location server 160 can use with regard to mobile device 105 OEM retailer, model and may version information, with regard to software or firmware version (be for example directed to mobile device 105 or Chipset in mobile device 105 or radio chipsets) information, and may with regard in mobile device 105 contained one or The information of multiple radio chipsets is to obtain the locating features of mobile device 105.Locating features can relate to the pass of mobile device 105 In a certain known capabilities of the positioning of mobile device 105, fault, restriction or other property.Location server 160 can be using positioning Ad-hoc location is supported to provide mobile device 105 or represent mobile device 105 to provide ad-hoc location to support by characteristic.Some positioning Characteristic is provided using the example providing position to support by location server 160 in Table 1 with it.

Table 1

For different OEM retailers, model and model version and different software or firmware released version and/or different core The Given information (the known locations characteristic of the type illustrating in such as table 1) of piece retailer, model and model version can be by position The service provider of server 160 or operator's configuration.Additionally or alternatively, this information can by location server 160 and/or Collected by another server as described further below.

The information search function of being supported by location server 160 is related to by the positioning according to many mobile devices 105 Collect the information of statistics and the mobile device 105 that collects with provide " Given information " that previously mentioned positioning supports function and " locating features " part or all of.For example, location server 160 observable is when the identical retailer of positioning, model, version With specific restriction during many different target devices of chipset, fault or other property.Location server 160 then can count According to this data that collects in storehouse to provide above-described positioning to support function.

This information search function is applicable to the example in table 1.For example, be support matrix 1 example A, location-based service Device 160 can be observed, and all target mobile device 105 of specific OEM retailer and model all can not measure and carry with Serving cell The different any LTE frequency of wave frequency rate, OTDOA value (for example when be instructed to execute this little measure when with error reaction, or can letter Singly ignore this instruction).

For the information search function of the example B of support matrix 1, location server 160 can be observed, and target 105 provides and is used for The RTT measurement of one or more WLAN AP, it does not enable the calculating of single position of target 105 or does not enable and use example Calculating as the position identical position of the target 105 of other localization method calculating such as A-GNSS or OTDOA.Location server 160 then should can calculated using a certain other more reliable approach (such as this A-GNSS or OTDOA) by estimating target 105 The position of target 105 at the RTT measurement that recorded and then obtain error E as the RTT recording with should record Difference between RTT, to estimate the error E in the RTT measurement being provided by target 105.If the value of error E is identical, close to identical Or there is general statistical distribution (such as normal distribution), then for by target 105 and the institute by identical OEM retailer and model There are all RTT measurements that other targets 105 make, location server can make error E (and the appointing of the E comprising average and variance What statistical distribution) equal with the delay D (and comprising any statistical distribution of the D of average and variance) describing for example B.Position Put the target 105 that server 160 can determine this OEM retailer corresponding to known error E (and equivalent delay D) and model whereby Locating features.Additionally or as a replacement scheme, location server 160 can simply attempt to different fixed errors E and come It is added from the RTT value recording of destination apparatus or deducts from the described RTT value recording, and the subtraction of specific fixed value E can be found Realize constant location estimation and/or the calculating of the location estimation consistent with the location estimation calculating using other localization methods. Location server can be observed, and the subtraction of same fixed value E also realizes being properly positioned of other destination apparatus of same type.

For the information search function of the example C of support matrix 1, location server 160 can be observed, and it can be using more than a certain The rssi measurement of threshold value (such as -50dBm) rather than the rssi measurement being used below this threshold value obtain the accurate location of destination apparatus. Location server 160 also can be observed, and in the case of the destination apparatus of identical OEM retailer and the version after a while of model, makes Accurate location may be obtained with the RSSI value less than previous threshold (for example going straight down to -70dBm).It is fixed that these observations can provide The information of position characteristic, such as the C in table 1.

For the information search function of the example D in support matrix 1, location server 160 can be assumed that generally works as acquisition using load When OTDOA RSTD between the reference unit R of wave frequency rate, F1 and the adjacent cell N using different carrier frequencies F2 measures, target Device 105 will comprise a certain deviation B (as example D description).Described hypothesis can be based on destination apparatus 105 potentially using mesh Different inner tracks (for example can comprise the different RF chains of different RF chips and/or different antennae) in device for mark 105 are processing With the RF signal being received under measurement different frequency.Deviation B then can be considered as extra known variables by location server, and its value can Unknown position coordinate (such as latitude, longitude and possible height above sea level) together with destination apparatus 105 is provided using destination apparatus 105 RSTD measurement and obtain.By deducting with RSTD measurement or be added deviation B from RSTD measurement, deviation B can be incorporated into In RSTD equation, RSTD equation by the RSTD measurement of cell R and N be linked to the position coordinates of destination apparatus 105 and cell R and The known location coordinate of the antenna of N.Deviation B can be incorporated in any other RSTD equation in the same manner, thus will be with reference to list First R and use are linked with the RSTD measurement of any other cell N* of cell N identical frequency F2.It should be noted that link is with reference to single First R and the RSTD equation being measured using the RSTD between the adjacent cell of cell R identical frequency F1 will not be come using deviation B Adjustment.This kind of Mathematical treatment is in the art it is known that and can making it possible to work as and there is not any deviation (i.e. deviation B etc. In 0) in the case of solve for destination apparatus 105 position and originally more RSTD compared in the RSTD measurement of minimum needs and measure By to the solution of RSTD equation, the position together with destination apparatus 105 obtains partially when (and therefore more RSTD equation) can use The value of difference B.Location server 160 can be from the use two of the other mobile devices offers being related to by identical OEM retailer and model The similar position of the RSTD measurement between individual carrier frequency F1 and the cell of F2 calculates the other values obtaining deviation B.Additionally, being used for Ad-hoc location calculate reference unit usage frequency F1 or frequency F2 may generally not have relation, as long as adjacent cell use Another frequency (for example, if reference unit usage frequency F2, usage frequency F1).Location server 160 then can be true Fixed identical OEM retailer and the fixed value of deviation B of all destination apparatus of model or the statistical distribution of deviation B (for example have Specific average and variance).This information then can store and form locating features (the example D description in table 1).It will be appreciated that Location server 160 can carry out a pair of cell of RSTD measurement for the destination apparatus of given OEM retailer and model for it Any other frequency is used in terms of different deviations B being used constructed obtains similar locating features.Location server Destination apparatus also can be worked as provides reference unit some neighbouring from use more than one frequencies different with the frequency of reference unit More than one deviation is determined during the RSTD measurement of the enough numbers carrying out between cell.Additionally, can be directed to by location server 160 Belong to many difference OEM retailer, model, versions and be likely to be of different radio chip and/or different software or firmware issue The destination apparatus of version obtain single deviation B of different pairs of frequency or some deviations.

From different OEM retailers, model and version, different software or firmware released version and/or different internal wireless core All information (being for example such as exemplified above) observed that the inferred locating features of the destination apparatus of piece are associated can by one or Multiple location servers 160 configure, and described location server 160 can share, with other positions server, the information that this observes. Therefore, the information that this observes can be supported using the positioning providing relatively early description by identical or by diverse location server after a while Function.Additionally, some different servers can jointly support information search function, each server is collected with regard to different types of The information of the locating features of mobile device.Although neither one server necessarily can have enough information all the time and exactly and can Know each locating features by ground, but when some or Servers-all information combination (for example, at single central server or Each of different server place) when, can be possible to more accurately and securely determine locating features.For example, with regard to by Any one server is in a small amount of mobile device (being for example directed to given OEM retailer and OEM retailer's model) of given type In the information (such as position measurement, numerical value etc.) of certain position characteristic observed can be with the phase with regard to being collected by other servers Similar information combination with the same or like locating features of mobile device of (or similar) type.As an example, by not The numerical value (for example, deviation B (the example D in table 1) or postpone D (the example B in table 1)) collected with server can be through By average or weight averaged and combine, or can be used for determining the statistical distribution (for example passing through to determine average and variance) of numerical value. Additionally, combined information can be used for determining whether locating features generally applicable (be not only for example for several mobile devices or pin Abnormal to the statistics of particular server), and if it is then determine that locating features are applied to all of specific OEM retailer All mobile devices of mobile device, specific OEM retailer and OEM retailer's model be still only applicable to specific OEM retailer, The mobile device of retailer's model and model version (or simply uses the OEM retailer of specific wireless chipset and the shifting of model Dynamic device).

In addition, and different from needing to be pre-configured with traditional skill of location server database for each mobile device type Art, the information search function of the information of compilation mobile device 105 can be applied to location-based service by using the information being provided The not previously known new mobile device of device 160.For example, location server 160 can receive OEM from a certain destination apparatus and sell Business, retailer's model, model version and may software or firmware released version and (for the no core of one or more in target Each of piece group) chipset retailer, model and model version identifier (ID).Location server 160 can not recognize Some or all (for example possible unused described ID configurations) in these ID.However, location server 160 can still execution information be searched Collection function, and observe and storage is with regard to the information of one or more locating features of destination apparatus, and make the ability that these observe It is associated and stores, with limiting, ability and the restriction that these are observed with the ID being received.Location server can similarly be directed to Identical group of OEM and radio chipsets ID be associated (or with for example identical OEM retailer ID and identical OEM retailer's model ID General subset Deng these ID is associated) other destination apparatus execution informations collect functions, and also these targets of observable fill Same or like locating features in putting.Location server then can in the case of numerical value locating features (for example, such as table 1 In example D in deviation B) for example via average or weight averaged or by inferring, there is the statistics of specific average and variance It is distributed and to combine the locating features of the same type of different mobile devices.Location server 160 or another location server can make With the information observed, (for example it can comprise the destination apparatus of whole or general subsets of shared its OEM and/or chipset ID Integrated positioning characteristic) come the time after a while pass through make from device receive OEM and/or chipset ID whole or general subsets with Previously stored ID mates and helps support the positioning of the destination apparatus of same type.Although ID can for location server 160 (for example the configuring in location server 160) known, but as just now described, this is not required in that, and information search can be for Not previously known OEM and/or chipset ID is possible.This can allow identification and adaptation in the case of no any being pre-configured with to treat The function of the mobile device 105 supported.Therefore, location server 160 can learn and to adapt to location server 160 not previously known New mobile device.

As an example, can be in the more recent version of phone, in the newer software of phone or firmware version and/or newer core The known fault of certain types of mobile phone is corrected in piece group.When initially using redaction, location server 160 can work as knowledge Using with for previous version identical function and locating features when not supporting for the positioning of mobile phone with adjustment, comprise Know fault.However, the analysis of the information being collected of redaction for mobile phone (for example, is derived from by accumulation in time The data of one or more mobile devices of redaction) can show, previous failures no longer occur, and therefore can be by location server 160 think and have corrected that.This then can provide positioning in location server 160 then to other mobile phones of new phone version It is used as the new definition characteristic of " Given information " and new phone version during support.

Given information alterable with regard to the locating features of certain types of mobile device.As detailed in this article in embodiment Description, locating features may indicate that different types of ability, restriction, fault and other of the positioning with regard to specific mobile device type Property.In addition and/or the replacement scheme as any other ability described herein, specific mobile device type is known In general locating features can comprise for example following information：Supported air interface (for example, LTE, CDMA, WCDMA, GSM, WiFi, bluetooth etc.), for given interface the measurement capability supported (for instance, it is possible to measurement RSSI, RTT, S/N, AOA, sight Survey the time difference (OTD), TOA, RSTD etc.), the GNSS system (if present) supported, station-keeping mode (for example, the UE being supported Auxiliary, be based on UE, independence etc.), aiding data type (for example, GNSS rough time, GNSS fine-time, the GNSS that supported Position prediction, GNSS year calendar, GNSS ephemeris, base station almanac, mark map, WiFi AP position/transceiver location, WiFi AP RF thermal map etc.), if or how whether mobile device can calculate position and (comprise to allow location server to calculate position and whether Support that hybrid position calculates).
