Background

The field

Disclosed aspect relates to Wireless Telecom Equipment, relates in particular to system, method and apparatus that the location in the Wireless Telecom Equipment is provided.

Background

Such as Wireless Telecom Equipments such as cell phone, portable computer being popularized rapidly during the decade in the past.These equipment become the multifunctional equipment that wide range of functions can be provided day by day.For example, cell phone of today also can comprise computing power, the Internet access, Email, text message sending and receiving, GPS drawing, digital camera ability, audio frequency/MP3 player, video-game ability, video broadcasting receiving ability etc.

Except that above listed all functions, mobile communication equipment can be equipped with positioning service---such as based on the module of GPS (GPS) and/or based on the module of communication network, this equipment that makes can be determined its position at any time, such as geographic position and/or network site.For example, location or positional information are used in the navigational system, and these navigational system are followed the tracks of the geographic position with respect to the destination of drawing on the map, and this type systematic can be bonded to such as in the Wireless Telecom Equipments such as cell phone.Yet, in Wireless Telecom Equipment, use locating information to be not limited to navigational system.Other application also can utilize positional information.For example,---such as call drop, withdraw from service (OOS) generation, call failure and/or the insert successful positions---benefit that can reside in performance tracker on wireless device inside or the external network layer from knowing the position that the execution incident takes place.In addition, the method for application is revised or upgraded to the environmental characteristics of many other applications exploiting equipment---position that comprises equipment---.

At present, there are the various operator schemes that are used to locate.For example, gps system can be dependent on based on movement station (based on MS) pattern, movement station auxiliary (MS is auxiliary) but pattern, stand-alone mode or any other known at present or know in the future row mode.Various patterns provide the distinct methods that is used to locate.

For example, in based on the MS pattern, wireless device obtains the information relevant with the location of gps satellite from network positions entity (PDE), and carries out location Calculation at the Wireless Telecom Equipment place subsequently.Satnav information is referred to as almanac data and almanac data.Almanac data is the coarse orbit parameter of all gps satellites in the system, and is considered to be in and reaches in several months effectively.By contrast, almanac data is the point-device track and the clock correction of each gps satellite, and is considered to only effective in 30 minutes.Therefore, in based on the MS pattern, wireless device can but be not to need acquired information all the time from PDE, this depends on the flow time or the length of time of satellite information.

In the MS auxiliary mode, wireless device and PDE exchange such as satellite communication information and/or base station information and/or with the position relevant based on network information, and receive the position that calculates from PDE.Like this, operate in order to make the MS auxiliary mode, wireless device need be communicated by letter with PDE.Therefore, by contrast, though utilize wireless signal to communicate by letter with PDE to carry out some location based on the pattern of MS, the MS auxiliary mode utilizes wireless signal to communicate by letter all to locate with PDE.

On the contrary, in stand-alone mode, all positioning functions are carried out at the wireless device place.Like this, stand-alone mode need not to utilize wireless communication signals to communicate by letter to position with PDE.Yet in stand-alone mode, wireless device is used to determine its position from the signal of at least three gps satellites.Therefore, when indoor making a try, stand-alone mode has high failure rate, maybe can not be received because satellite-signal is very weak, and the MS auxiliary mode preference pattern when indoor making a try normally, because the communication network signal usually can be in office be where exchanged between wireless device and the wireless network.

In present practice, be suitable for the GPS pattern by application definition, or choose in the initialization/unloading phase of wireless device, the latter is a kind of method of paying no attention to the situation that wireless device experiences, wherein these situations may influence the location possibility of success.Institute's lectotype like this, institute's lectotype is applied to Location Request, even may not be to be optimal mode for given occasion.For example, the term of execution that various situations may being present in application whole, these situations are relevant with the validity of institute's lectotype.For example, the MS auxiliary mode utilizes wireless communication signals---such as CDMA (CDMA) signal or GSM (global mobile system) signal or UMTS (Universal Mobile Telecommunications System) signal, therefore, if it is auxiliary that institute's lectotype is MS, then under the sluggish situation of wireless signal or can not set up under the situation with maintenance call, the location will can be not successful.Other situation that influences the performance of station-keeping mode has: the flow time or the length of time of the current environment of equipment, battery charge level, audio call state, data call state, PDE satellite information.

Therefore, need overcome owing to the location mortality of choosing station-keeping mode at the initial phase of application layer or wireless device.Described method and apparatus should be taken into account the situation that exists in the moment of making the location, to guarantee to locate possibility of success.

For example, in some respects, be characterised in that at the wireless device place based on the location of MS pattern 48 and use positioning function 65 to carry out the calculating of device location.Though can utilize such as PDE supplementarys 56 such as almanac data 58 and/or almanac data 60 based on MS pattern 48 and to help obtain gps signal, each location is attempted can not comprising with PDE 18 and is communicated by letter under the current situation that is enough to determine the position of PDE supplementary 56.For example, in some respects, lucky first based on MS between trial period, locating module 30 will be downloaded almanac data 58 and almanac data 60.Yet, should be noted that this information can otherwise catch.Afterwards, locating module 30 can be carried out ephemeris and verify and investigate almanac data 60, to understand whether any satellite of lift-off is recently arranged, and under the situation of needs, will please look for novelty based on the number of the visible satellite that has its fresh almanac data 60 or upgraded almanac data 58.For example, depend on the size of satellite network, ephemeris is verified the request to renewal PDE supplementary 56 that can cause generation in per 30 to 90 minutes.When wireless device upgraded PDE supplementary 56, wireless device was just communicated by letter with PDE18 to obtain current almanac data 58 and/or almanac data 60 by communication link via wireless network.In case PDE supplementary 56 has been verified or obtained to wireless device, wireless device just uses PDE supplementary 56 to be provided for receiving the parameter of gps signal, and receives subsequently from the time-base signal of gps satellite broadcasting.In case receive gps signal, the PDE supplementary 56 that wireless device just is used to help decoding parametric is set is come decoded signal.Wireless device uses through when decoding base information subsequently and carries out positioning function 65 and determine device location 36.

More specifically, in another example, use gpsOne ^TMSolution be to have some assistant GPSs that mix abilities to realize based on MS pattern 48.In this pattern, wireless device does not directly utilize the CDMA pilot phase to measure (PPM) in location Calculation, thus the indoor positioning ability is limited in the zone that can detect enough gps signals.Yet, based on gpsOne ^TMThe MS pattern can utilize some local network parameters to promote acquiring satellite number of times and device sensitivity, thereby realizes the locking time and the availability of lifting with respect to the independent GPS solution of typical case.

MS auxiliary mode 50 location are characterised in that at PDE 18 places carries out the calculating of device location, and like this, at using each location trial generation of MS auxiliary mode and communicating by letter of PDE 18.If wireless device is selected to upgrade PDE supplementary 56, then wireless device is communicated by letter to obtain current almanac data and/or almanac data with PDE 18 by wireless network.In case PDE supplementary 56 has been verified or obtained to wireless device, wireless device just uses PDE supplementary 56 to be provided for receiving the parameter of gps signal, and receives subsequently from the time-base signal of gps satellite broadcasting.In case receive gps signal, the PDE supplementary 56 that wireless device just is used to help decoding parametric is set is come decoded signal.Wireless device uses through the time base information of decoding and makes and measurement apart from the distance dependent of gps satellite, and wireless device conveys to PDE with this metrical information.PDE 18 uses metrical information and carries out positioning function 65 to determine the position of wireless device.Therefore,, need wireless network signal or communication link, because MS auxiliary mode 50 utilizes and the communicating by letter of PDE18 for MS auxiliary mode 50.

More specifically, in another example, use gpsOne ^TMThe MS auxiliary mode 50 of solution uses wireless device to gather satellite data and the CDMA pilot phase is measured (PPM).This information is used for calculating the position of wireless device by PDE.Wireless device serves as sensor in essence to realize the position calculation on the PDE.PDE provides sensitivity again and catches supplementary, and this is caught supplementary and greatly promotes GPS sensitivity, system availability, landform covering and accuracy, and the execution location Calculation provides the position---be also referred to as locking.By utilizing the PDE supplementary, MS auxiliary mode solution provides the GPS sensitivity and the accuracy of highest level, eliminates basically the cold start-up time simultaneously.Use the degree of depth indoor positioning ability of pilot frequency information realization except that promoting the AGPS performance concomitantly based on CDMA.

Stand-alone mode 52 is characterised in that and carries out the calculating of device location and do not communicate by letter with PDE18 on wireless device.Yet, and to compare with pattern Network Based based on MS, MS are auxiliary, stand-alone mode 52 is normally handled the most intensive location, so the maximum powers of battery of stand-alone mode utilization.During when wireless device is outside cellular footprint, when wireless device does not have visit to PDE or in the expectation minimization data service, can utilize independent GPS pattern operation.Even this type of regional typical case be when lacking communication link therein navigation and/or location also may be spendable navigate or outdoor/hikings/camping environment in, perhaps alternatively, in the areal coverage of contour utilization application such as fleet management.In stand-alone mode, wireless device receives from the time-base signal of gps satellite broadcasting.Wireless device uses time-base signal and carries out positioning function 65 and determine device location.

In some respects, model selection routine 32 can be configured to order by test of many times to manage successfully to determine position 36.In addition, model selection routine 32 can be configured to provide repeatedly trial in this test before routine is abandoned given test and moved to next test in the sequence.Provide a kind of mode selecting method with the Fig. 4 that is described in more detail below, this method is passed through each test based on order, and attempts repeatedly the location and attempt in given test.Order is by a plurality of tests and allow repeatedly attempting in the given test make model selection routine 32 to make based on validity, efficient, passing performance and the power of battery of each orderly pattern to be used for each pattern is according to priority arranged.For example, in some model selection routines 32, based on MS pattern 48 can be first pattern in the sequence, because it provides the high relatively probability of success, only utilizes under PDE supplementary 56 requires news more and the radio communication of PDE and the restriction use to the power of battery.On the contrary, in some routines 32, stand-alone mode 52 can be the final mode in the sequence, and can be limited to once trial, because it utilizes very high amount of battery power.

In other respects, the one or more existing situation that model selection routine 32 can be configured to determine the influence location and/or influence equipment performance, and identifying and/or preference pattern based on determined existing situation subsequently.The example of existing situation includes but not limited to: such as CDMA (CDMA) signal condition or global mobile system (GSM) signal of communication state, Universal Mobile Telecommunications System (UMTS) signal condition, Wireless Fidelity (Wi-Fi) signal condition, current wireless signal conditions such as micro-wave access to global intercommunication (WiMAX) signal condition, such as almanac data, almanac data etc. are from the current state of PDE information conveyed, such as the audio call state, current communications status such as data session state, current battery power status, such as the observability of gps satellite or receive current environment condition status such as signal intensity, and any other can influence the existing situation of location.

Therefore, model selection routine 32 can be communicated by letter with wireless signal monitor 62 to determine the current state of wireless signal, for example with determine with the communication link of wireless network whether and/or can be established and safeguard.In addition, whether model selection routine 32 can be communicated by letter with audio call module 64 enlivens to determine that audio call is current, and whether communicate by letter with data call module 66 current active with the specified data session.In addition, model selection routine 32 can be communicated by letter with PDE supplementary 56 to determine the length of time or the flow time such as PDE supplementarys such as ephemeris several 58 and almanac data 60.In addition, model selection routine 32 can be communicated by letter with battery monitor 68 to determine current battery power levels.In addition, select routine 32 can communicate by letter with other environmental aspect modules 70 to determine other environmental aspects of influence location and/or equipment performance.

It should be noted that, though locating module 30 and assembly thereof and wireless signal monitor 62, audio call module 64, data call module 66 and battery monitor 68 are illustrated as module and the monitor that resides in the storer 24 in the wireless device 10 of Fig. 2, but in other respects, other system components that in these modules or the monitor any or all can be used as wireless device 10 exist, in the processing subsystem 42 that is present in processor 22.

Except that selecting the station-keeping mode based on existing situation, determined existing situation can be used in the model selection routine 32 to hang up or to cancel the execution of corresponding station-keeping mode.For example, some situation---such as making simultaneous audio call or the data call that attempt the location---can have a negative impact to the performance of audio call or data call.In some respects, with reduce the equipment user by audio call or data call are had a negative impact and experience different, model selection routine 32 can be configured to postpone the routine predetermined amount of time or finish until audio call or data call, and perhaps model selection routine 32 can be configured to cancel the execution of location.

Model selection routine therein 32 is configured to determine more than one in existing situation and the example based on this existing situation preference pattern more than one, to the selection of pattern can be based on a plurality of situations and/or pattern according to priority arrange, to a plurality of situations and/or pattern weighting and/or realize any other be used for relatively another situation or pattern ranking or emphatically situation or pattern so that can select the logic decision process of a pattern.

In some respects, model selection routine 32 can be configured to determine one or more existing situations and further determine whether to attempt enabled mode based on existing situation.For example, on the one hand, wireless device can be limited to a station-keeping mode.In this regard, can determine one or more existing situations, and can decision making about whether continuing to attempt station-keeping mode based on existing situation subsequently.For example, if wireless device is limited to MS auxiliary mode location, and one of existing situation is the situation of wireless signal or communication link, then determines the current unavailable trial that will cause not making to using the MS auxiliary mode to locate of wireless signal or communication link.

In addition, in some respects, model selection routine 32 can be configured to determine one or more existing situations, and determines that based on existing situation which pattern is the optimal mode that is used to locate or determines for mode sequence of the best of location usefulness or the mode list of according to priority arranging.Should be noted that can be according to producing the highest pattern of successfully locating possibility or using the pattern of minimal equipment stock number or the pattern of the suitably use of balance success possibility and limiting device resource or the pattern that other wireless device services are had minimum influence define optimal mode.

Particularly, as following illustrated in reference to Fig. 6 and 7 methods of being discussed, in some respects, model selection routine 32 can regulation in proper order by a plurality of tests, allow the repeatedly trial in the given test, and in a test or in the predetermined one or more existing situation of determining the influence location in the sequence of testing.

Therefore, wireless device 10 comprises and can determine station-keeping mode, attempt the location and preserving determined position under the situation of trial and success and attempting the module and the logic of preserving the unsuccessful designator of attempting of indication under the unsuccessful situation based on the model selection routine in response to Location Request.

Referring to Fig. 3, provided the process flow diagram of the method for the position that is used for definite Wireless Telecom Equipment.In incident 100, receive request to the location.This request can be to be received from the internal request of utilizing the application of location such as mapping or navigation application, performance diagnogtics application etc., and perhaps this request can be the external request that wirelessly is received from the network equipment or entity.

In incident 110, identify at least one station-keeping mode based on the model selection routine in response to Location Request.It should be noted that: in some instances, wireless device may only have an available station-keeping mode, and in this case, this unique enabled mode will be the determined institute of model selection routine markers.As discussed previously, in some respects, the mark location pattern can comprise order by a plurality of tests and allow the repeatedly location in the given test to attempt, and/or determines the one or more existing situation of influence location and based on determined existing situation preference pattern.Wireless device only has the particular aspects of an available station-keeping mode therein, and the model selection routine can be determined existing situation, and based on existing situation, makes definite about whether attempting enabled mode.In other respects, the model selection routine can be determined existing situation, and based on existing situation, determine optimal mode in the middle of a plurality of station-keeping modes or general wherein the pattern ranking or sort by priority, perhaps be identified for the optimal sequence of execution pattern.

In incident 120, the pattern that is identified is performed to try hard to obtain the position of Wireless Telecom Equipment.In some respects, institute's lectotype can be attempted repeatedly the positioning result until success.In other respects, such as when implementation pattern sorts, an optional majority pattern, and predetermined order is carried out the positioning result until success.Should also be noted that: in some instances, the execution of institute's lectotype or all institutes lectotype can cause the location failure.Exist therein in some examples of particular condition, the location failure can be the receptible result of position fixing process, guaranteeing the integrality of other functions of the equipments, do not interrupt execution, battery power levels etc. such as Another Application on audio call or data call quality, the equipment.

In incident 130, the result who attempts the position of acquisition wireless device is stored in the storer.With the result who attempt to obtain the position be stored in can relate in the storer position returned to the internal application of request location and with location storage in using, the result that perhaps will attempt obtaining the position is stored in can relate in the storer and the position is conveyed to the network devices/entities that request locatees and subsequently the position is remotely being stored in the network data base.

Referring to Fig. 4, a kind of one side of the method that is used to locate comprise model selection routine operation with based on order by a plurality of tests and allow the repeatedly trial in the given test to identify and execution pattern.In incident 200, receive request to the location.As discussed previously, request can be to be received from the internal request of application or request can be the external request that is received from network devices/entities.

In incident 210, use first station-keeping mode to be made a try in the location.First station-keeping mode is first pattern in the mode sequences and defines first test.Sequence order can based on the efficient that influences position fixing process and validity and on wireless device, just carrying out other use and the various factors of the validity of feature is determined.

In incident 220, whether successfully make definite in the position of definite equipment about trial.If attempt locating successfully, then in incident 230, with location storage in internal storage or in the external memory storage such as long-range or removable equipment.Get nowhere if attempt locating, then in incident 240, about whether making definite at the additional trial of the first test execution.In this, model selection routine can be configured to provide once above trial to given test.For example, model selection routine can be configured to be defined in order and proceed to and use first station-keeping mode to carry out the trial of pre-determined number before second station-keeping mode.If first test has additional trial available, then routine will turn back to incident 210, and use first station-keeping mode to make additional the trial.

If first test does not have other trials available, then in incident 250, routine proceeds to second station-keeping mode with order, and uses second station-keeping mode to come to be made a try in the location.

In incident 260, whether successfully make definite in the position of definite equipment about trial.If attempt locating successfully, then in incident 270, memory location in the above described manner.Get nowhere if attempt locating, then in incident 280, about whether making definite at the additional trial of the second test execution.If second test has additional trial available, then routine will turn back to incident 250, and use second test to make additional the trial.

Order is by testing successfully to locate the final test of proceeding in meeting with sequence.Fig. 4 illustrated aspect, the final test in the sequence is the defined n test of n station-keeping mode, wherein n is a positive integer.The n test can be second test in the sequence, perhaps can be any follow-up test in the sequence.Continue the description of above method, if second test does not have other trials available, then in incident 290, routine proceeds to the n test with order, and uses n station-keeping mode to be made a try in the location.In incident 300, whether successfully make definite in the position of definite equipment about trial.If attempt locating successfully, then in incident 310, memory location.Get nowhere if attempt locating, then in incident 320, about whether making definite at the additional trial of n test execution.If the n test has other trials available, then routine will turn back to incident 290, and use n pattern to make additional the trial.If there are not other trials available, then in incident 330, position fixing process finishes, and in this example, does not successfully locate.

Referring to Fig. 5, a kind of one side of the method that is used to locate comprises that the operation of model selection routine is with the existing situation of definite influence location and based on determined existing situation preference pattern.In incident 400, receive request to the location.As discussed previously, request can be to be received from the internal request of application or request can be the external request that is received from network devices/entities.

In incident 410, in response to receiving Location Request, wireless device is determined the one or more existing situation of influence location.For example, existing situation can be scheduled to, and is comprised as the part of model selection routine 32.The example of existing situation includes but not limited to: such as CDMA (CDMA) signal condition or global mobile system (GSM) signal of communication state, Universal Mobile Telecommunications System (UMTS) signal condition, Wireless Fidelity (Wi-Fi) signal condition, current wireless signal conditions such as micro-wave access to global intercommunication (WiMAX) signal condition, such as almanac data, almanac data etc. are from the current state of PDE information conveyed, such as the audio call state, current communications status such as data session state, current battery power status, such as the observability of gps satellite or receive current environment condition status such as signal intensity, and any other can influence the existing situation of location.

In incident 420, come the mark location pattern based on one or more existing situations.For example, if existing situation is defined as the current state of wireless signal or wireless communication link, then routine can be selected the pattern based on MS under the current situation that does not have wireless signal or wireless communication link to use, and perhaps routine can be selected the MS auxiliary mode under the situation that wireless signal or wireless communication link can be used.More than one therein existing situation is determined and is used for the example of preference pattern, can be to each of situation and/or each arrangement according to priority, weighting and/or the relative to each other ranking in addition of pattern.For example, can come each of these a plurality of situations of weighting based on each of a plurality of situations with respect to the importance of the successful possibility of given station-keeping mode.In addition, for example, can use just suitable weighting algorithm or any other decision-making mechanism to come based on a plurality of situation preference patterns.Except that based on the existing situation preference pattern, this method also can be stipulated to hang up or the realization of cancellation pattern based on existing situation.For example, if situation is defined as the current state of voice or data call, then routine can be configured to postpone or cancel the execution of station-keeping mode and/or routine.

Wireless device only has a particular aspects of an available station-keeping mode therein, and the model selection routine can be determined existing situation, and based on existing situation, makes definite about whether attempting enabled mode.In other respects, the model selection routine can be determined existing situation, and based on existing situation, determines the optimal mode that a plurality of available station-keeping modes are central or the optimal sequence of deterministic model.

In incident 430, the pattern that is identified is performed to try hard to obtain the position of Wireless Telecom Equipment.As previously discussed, in some instances, the execution of institute's lectotype or all institutes lectotype can cause the location failure.

In incident 430, the result who attempts the position of definite wireless device is stored in the storer.As previously discussed, the result who attempts the location is stored in can relate in the storer position is returned to the internal application of request location, memory location internally, the result that perhaps will attempt the location is stored in can relate in the storer and the position is conveyed to the network devices/entities that request locatees and subsequently the position is remotely being stored in the network data base.

Referring to Fig. 6, an aspect of the ad hoc approach that is used to locate comprises that the operation of model selection routine is to pass through a plurality of model tests in proper order, one or more the comprising having determining of situation now in wherein all tests.Three model tests of illustrated aspect regulation are used for the location, yet, should be noted that and can use n test.First station-keeping mode is selected in first test 500, and can attempt this more than test once before moving to second test.Second test 510 is selected or first or second station-keeping mode based on determined existing situation, and can move to the 3rd or the n test before hit and miss experiment once more than.N test 520 selects n station-keeping modes also to attempt this pattern once, if the trial of n pattern is got nowhere, and then routine end and do not have positioning result.

In incident 530, use first station-keeping mode to be made a try in the location.In incident 540, whether successfully make definite in the position of definite equipment about trial.If attempt locating successfully, then in incident 550, with location storage in internal database or in the external data base such as network data base.If it is unsuccessful to attempt the location, then in incident 560, about first test whether have additional attempt available make definite.In this, model selection routine can be configured to specifying test that once above trial is provided.If first test has additional trial available, then routine will turn back to incident 530, and can use first station-keeping mode to make additional the trial.

Whether if first test does not have other trial available, then in incident 570, routine proceeds to second test 510 with order, and influence the existing situation of locating and make definite about running into.For example, any other situation of defined existing situation current state that can be wireless signal or influence location.If do not run into these situations,, use first station-keeping mode to be made a try in the location then in incident 580.It should be noted that: do not require first pattern of use; Under the situation that does not run into these existing situations, can use any other enabled mode.If run into these existing situations,, use second station-keeping mode to be made a try in the location then in incident 590.

In incident 600, whether successfully make definite in the position of definite equipment about trial.If attempt locating successfully, then in incident 610, with location storage in internal database or in the external data base such as network data base.If it is unsuccessful to attempt the location, then in incident 620, about second test whether have additional attempt available make definite.If second test has additional trial available, then routine will be returned incident 570, and select to determine whether to run into existing situation before the pattern that will be used to attempt locating.

If second test does not have other tests available, then in incident 630, routine proceeds to n test 520 with order, and uses the n pattern to come to be made a try in the location.In incident 640, whether successfully make definite in the position of definite equipment about trial.If attempt locating successfully, then in incident 650, with location storage in internal database or in the external data base such as network data base.If the not success of trial location, then in incident 660, position fixing process finishes, and in this example, does not successfully locate.As discussed previously, the n test 520 in the illustrated aspect of Fig. 6 is configured to only stipulate once to attempt about the n station-keeping mode.

Referring now to Fig. 7,, the one side of the ad hoc approach that is used to locate comprises that the operation of model selection routine is to pass through three tests in proper order, in given test, attempt the location repeatedly, determine the existing situation in second test, and select next pattern that to carry out based on determined existing situation.Three tests are stipulated to model selection in illustrated aspect, yet, can utilize n test.In this case, three test models and relatively ordering be scheduled to so that the minimization device resource is used and is convenient to minimize such as the interruption of the use of other services such as audio call on the equipment or the degradation of its quality.

In addition, although be described as order by three tests, yet in this regard, the model selection routine also can be described to choose in the middle of the set of first station-keeping mode based on the set of first situation.Subsequently, depend on the result, from the set of second station-keeping mode, choose that the rest may be inferred based on the second situation set different etc. with first situation set.Like this, each in operation order can with because of the different set of modes of order and/or be used for determining selecting which be associated because of the different situation set of order of corresponding modes.Should be appreciated that it can be identical that station-keeping mode set and situation are gathered for each order in each routine and/or the routine, perhaps can be depending on the specific purpose of given realization of model selection routine and difference.

First test 700 utilizes based on the MS pattern and locatees more than can attempting once before moving to second test and attempt.Second test 800 is selected based on the current wireless equipment state or based on MS pattern or MS auxiliary mode, and can move to the 3rd or the n test before attempt once the trial of above location.The 3rd test 900 selects stand-alone modes also to attempt the pattern pre-determined number, if all trial of stand-alone mode are all got nowhere, and then routine end and do not have positioning result.

In incident 702, make definite to the new request of the location that is called the GPS locking in addition about whether having.If define new request,, whether support to make definite based on MS pattern location about wireless device then 704 to the location.If do not support that based on MS pattern location, then routine will be skipped first test 700, and move to second test 800 immediately.If the wireless device support based on MS pattern location, then in incident 706, is used based on the location of MS pattern and is attempted positioning.In incident 708, whether successfully make definite in the location about trial.If trial and success, then in incident 710, with location storage in the Local or Remote storer.

If attempt getting nowhere, then routine will be returned incident 702, to determine whether the request to the location is new request.If request is not new request,, whether be that the last trial that test is disposed is made definite about previous trial then in incident 712.Test can be configured to allow the one or many location under this test to attempt.If make previous trial and be not determining of last trial that test disposed, then in incident 706, use and make another time based on the location of MS pattern and attempt, and in incident 708 with the location, make and follow-uply determining to determine to attempt whether success.If trial and success, then in incident 710, the memory location, whether if perhaps attempt getting nowhere, then routine is returned incident 704, there, be that the last trial that test is disposed is made definite about previous trial.In case the last trial in the test is not successfully finished, then finish first test 700, and routine moves to second test 800.

In incident 802, whether there is trial to can be used as definite about second test.Similar with first test, second test can be configured to allow repeatedly to attempt so that use second test to obtain the position.If attempt availablely,, carry out determining to existing situation then in thing 804.Particularly, in incident 804, about wireless signal current whether available make definite.If there is not wireless signal to use,, whether support to make definite based on MS pattern location about wireless device then in incident 806.If support,, use based on the location of MS pattern and attempt positioning then in incident 808 based on MS pattern location.If do not support,, use the location of MS auxiliary mode to attempt positioning then in incident 810 based on MS pattern location.As discussed previously, the MS auxiliary mode utilizes wireless signal to communicate by letter with PDE, because in the MS auxiliary mode, location Calculation is finished on PDE.Therefore, in order to make this trial and success, wireless signal must have and become available, determines because made in incident 804.In case to the location carried out attempting (or incident 808 or 810), just definite 812 about attempting whether successfully making.If trial is successfully located, then routine is returned incident 802 to determine whether second test has additional trial available.If trial and success, then in incident 813, the speed of making is verified to determine whether the location comprises speed parameter.If the location comprise speed parameter, then in incident 814, with location storage in inside or external memory storage.If the speed verification determines that the location does not comprise speed parameter, then routine is returned incident 802 to determine whether second test has additional trial available.

If make determining that wireless signal can use in incident 804, then in incident 816, about radio frequency (RF) emission/reception (Tx/Rx) chain of for example wireless communication link current whether available make definite.If RF Tx/Rx chain can be used,, use MS auxiliary mode location to attempt positioning then in incident 810.If RF Tx/Rx chain is unavailable, then in incident 818, about audio call current whether making definite.If audio call carries out, then in incident 820, can hang up one schedule time of location amount, perhaps straight notice such as scheduled events such as end of callings.Usually, attempting the location during audio call will influence the quality of audio call unfriendly, so position fixing process is not suspended so that user's voice calling experience is not caused adverse effect.Currently do not have that audio call is ongoing to be determined if make, then in incident 822, about data call/session current whether making definite.If there is not data session to carry out,, use MS auxiliary mode location to attempt positioning then in incident 810.If data call/session is carried out, then in incident 824, the idle predetermined amount of time of routine or until the notice of end of calling is striven for data session finishes after and is waited for and attempt locating trying hard to.After the predetermined empty lots,, use MS auxiliary mode location to attempt positioning in incident 810.In case attempt the MS auxiliary mode, just whether successfully make definite about trial in incident 812.If trial and success, then in incident 814, with location storage in inside or external memory storage.If attempt successfully not locating, then routine is returned incident 802 to determine whether second test has additional trial to carry out.If second test does not have other trials available, then finish second test and routine and move to the 3rd test 900.

Whether in incident 902, it is definite to support stand-alone mode to make about wireless device.If do not support stand-alone mode,, do not having to finish routine under the situation of successfully locating then in incident 904.If the support stand-alone mode, then in incident 906, about independent experiment attempt whether available make definite.If there do not have independent experiment to attempt to be available,, do not having to finish routine under the situation of successfully locating then in incident 904.If it is available that stand-alone mode is attempted,, use the stand-alone mode location to attempt positioning then in incident 908.In case whether the trial stand-alone mode just successfully makes definite about trial in incident 910.If trial and success, then routine is returned incident 906, and about additional stand-alone mode attempt whether available make definite.If trial and success, then in incident 914, with location storage in inside or external memory storage.
