On the other hand, some transmitting sets can broadcast its position, and this type of positional information can be stored in shifting In one or more data bases in dynamic station, such as it is stored in the transmitter data base 250 of movement station 322. Such as, this type of transmitting set positional information can with other network entity share, such as secondary server or Location server 170 location server such as grade of such as Fig. 1.

Additionally, on the other hand, BSA240 can store the BSA185 of the most for example Fig. 1 wherein Subset Deng bigger BSA data base.On the one hand, such as location server 170 or BSA server 180 Can determine that and be stored in Deng network entity in the associated plurality of transmitting set of the information in BSA185 Which transmitting set makes it possible to one or more signal and is obtained by movement station 322, and can enter one Step determines that each transmitting set in the plurality of transmitting set is to movement station 322 navigation operation in the future Expection contribution.As set forth above, it is possible to be based at least partially in the following one or more determine right The expection contribution of movement station in the future: accuracy, covering are observed in range capability, expection measurement accuracy, expection Area size or the information about each transmitting set importance in the navigation operation in past.Additionally, The probability that one or more signal obtained by movement station 322 of making for each transmitting set can be down to It is at least partly based on the adjacency of individual transmitter and the current location of movement station 322.On the other hand, this can Energy property can be based at least partially on movement station 322 within a period of time in past and obtain from individual transmitting set The number of times of the number of winning the confidence.On the other hand, this probability can be based at least partially on individual transmitter and movement station The adjacency of the history route of 322.This probability can based on other example of information comprise the steps that movement Stand various Radio Access Type that 322 Radio Access Type supported, movement station 322 supported The Radio Access Type and the individual radio transmitter that currently enable on utilization rate, movement station 322 make Obtaining the frequency that signal is obtained by other movement stations multiple, other movement station the plurality of is to such as location server 170 webservers such as grade report that it is observed.Certainly, these only can be used for determining for multiple wireless Penetrate the letter of the probability that one or more signal is obtained by movement station of each transmitting set in machine The example of breath, and the scope of subject content required for protection is not limited in this respect.

On the one hand, in order to make the such as network entity such as location server 170 or BSA server 180 determine The possibility that expection is contributed and made one or more signals of specific wireless transmitter be obtained by movement station 322 Property, this network entity can receive information from movement station 322.As it has been described above, movement station 322 can be at lock Given data storehouse 230 is collected the information about position lock operation, including identifying and be positioned at position locking behaviour The information of the transmitter observed during work.For an example implementation, can be by the letter about particular transmitter Breath is stored in transmitter data base 250.In an example implementation, it is stored in lock database 230 or sends out The information in machine data base 250 of penetrating is provided to such as location server 170 or BSA server 180 Deng network entity.The information being provided to cordless communication network 120 can provide to cordless communication network 120 Enough information determines that the one or more signals making at least some of transmitting set are obtained by movement station 322 Probability.Certainly, as can determine that about the movement station past from the information of the transmitter of its acquisition signal, Also can determine that about movement station the most not yet from the information of the transmitter of its acquisition signal.On the one hand, movement station Past not yet can be confirmed as having make one or more signal by movement station from its transmitter obtaining signal The 322 relatively low probabilities obtained.

Fig. 3 is that depicted example base station almanac (BSA) server 350 is via the most for example WLAN332 With one or more cordless communication networks 330 of cellular network 334 and via the Internet 340 and several shiftings The diagram that dynamic station 320 communicates.For this example, movement station 322 can represent can be supported and packet switch The multimode device communicated of wireless lan (wlan) 332 and both cellular networks 334.Certainly, this It is only the example of the cordless communication network type that multimode device communicates, and theme required for protection Scope be not limited in this respect.And, for this example, movement station 324 can represent can be supported and honeybee The single mode device of the communication of nest network 334.Again, cellular network only can be set up with movement station and communicate One example of cordless communication network.

Fig. 3 further depict movement station 320 several transmitter types 310 capable of being monitored.Movement station 320 may Any given network subscribed or be not subscribing to be associated with each corresponding transmitter type is so as to monitor from respectively The signal that transmitter type is launched.Therefore it provides can include or may not include to the BSA information of movement station The information not being associated to its network subscribed with movement station.If request BSA information, then movement station is permissible Specify specific network or specific transmitter type.For the example of Fig. 3, one or more movement stations 320 Can ask to include the BSA information of at least one subset of the BSA from BSA server 350.

On the other hand, BSA server 350 can obtain BSA from outside almanac source 360.Such as, honeycomb Network provider can be signed a contract with third party and developed BSA information or provide to BSA server 350 BSA information.At least one subset of this information finally can be transmitted to one or more movement station 320.Another Aspect, sends out when one or more movement stations 320 are delivered from one or more example at least partially through supervision When penetrating the signal of machine 310 to form this type of information, BSA server 350 can receive from one or more shiftings The BSA information at dynamic station 320.It addition, on the other hand, outside one or more movement stations 320 are optional Whether the BSA information that portion provides should make this type of request in response to movement station and be delivered to movement station, Or whether the BSA information initially formed by movement station at least in part should be delivered.On the other hand, The optional combination from the outside information with local source of one or more movement stations 320.

Although the example of Fig. 3 depicts two movement stations, but actually presents the difference in functionality of broad range Or the various movement station types of storage capacity can be used to and diversified potentially possible network Type communication.Additionally, movement station can present the different purposes pattern of broad range.Therefore, for BSA For server 350, it is provided that the personalized subset of BSA information that each movement station may require or asks It is probably useful, and provides in a flexible way according to specified file size, the area of coverage or transmitter class This type of information of several format samples that type is only exemplified by assignable parameter is probably further Useful.One aspect, these parameters can be specified by movement station.

On the other hand, its information is by the BSA information being included in the movement station being provided to make request Transmitter can make the neighbour of the current location estimated by movement station of request with this according to each transmitter Recency determines.This for determining will provide which technology of BSA information to the movement station making request Idea behind is that the movement station making request more likely obtains its overlay area in the future of relative close Signal with those transmitting sets that the appointment geometry around the position estimated by movement station intersects. On the one hand, this shape can include having the appointment half extended from the position made estimated by the movement station of request The circle in footpath.As an example, if the individual overlay area of a transmitter is intersected or complete with this shape Entirely surrounded by this shape or (center of such as, the estimated area of coverage is in this shape in somewhere betwixt Portion), then give transmitter and its information can be included in the BSA information of the movement station being supplied to make request In.As another example, the data available can being based at least partially in the movement station of the request of making storage comes Be made whether conditionally to be included in the information about a given transmitting group of planes to make request by being provided to Judgement in the BSA information of movement station.Such as, space availability is depended on, it may include or individual Penetrating machine or launch the information of a group of planes, information of wherein adding is until reaching BSA information size threshold value.BSA The big I of information is such as based on largest amount or the expectation making data available storage in the mobile device of request Size.

For instantiation procedure 400, network almanac 410 can be divided into multiple regionality and go through by zone manager 420 Book subregion 430 and multiple sparse network almanac (SNA) 440 subregion." sparse network almanac " is permissible Relate to the almanac including each packet of base station or access point.Packet generally can with in almanac and lower layer region thereof The hierarchical identity element of each represented network is associated.Regional almanac subregion 430 can include base area Reason region divide (as the term suggests) more detailed information.

On the one hand, download manager 450 can determine that and will download 460 provide which to movement station 322 by mobile A little information.On the one hand, download manager 450 can be based at least partially on and be stored in network almanac 410 In the future of movement station 322 the is navigated expection contribution of operation of each transmitting set of being associated of information come Select to be provided to the information of movement station 322.For example, it is possible to be based at least partially in the following One or more determine expection contribution: range capability, expection measurement accuracy, expection observe accuracy, Overlay area size or the information about each transmitting set importance in the navigation operation in past.With Sample, can be based at least partially on and be stored in associated plurality of wireless of the information in network almanac 410 Penetrating which transmitting set in machine may make one or more signal be selected letter by movement station 322 acquisition Breath.This probability can be based at least partially on the neighbouring of individual transmitter and the current location of movement station 322 Degree, or on the other hand, this probability can be based at least partially on movement station 322 within the past period The number of times of signal is obtained from individual transmitting set.As other example, this probability can be at least in part Adjacency based on individual transmitter with the history route of movement station 322, or on the other hand, this probability The Radio Access Type that movement station 322 is supported can be based at least partially on.Probability also can at least portion Divide ground based on the utilization rate of various Radio Access Type that movement station 322 is supported, movement station 322 The Radio Access Type that currently enabled or may also be based at least in part on individual transmitting set and make The frequency that signal is obtained by other movement stations multiple, other movement station the plurality of is to such as download manager 450 Report that it is observed Deng network entity.Certainly, these only can be used for determining in multiple transmitting sets The showing of the information making probability that one or more signal obtained by movement station of each transmitting set Example, and the scope of subject content required for protection is not limited in this respect.

On the one hand, movement station 322 can provide the request to network almanac information by upload manager 470, And the request of downloading 401 can be forwarded to download manager 450.Equally, as it has been described above, movement station 322 Can provide to network entity (example described for Fig. 4 it include upload manager 470) and be stored in Wireless transmit machine information in lock database 230 or transmitter data base 250.Upload manager 470 is also The wireless transmit machine information from other movement stations multiple can be collected, and these information can be added to network Almanac 410.On the other hand, represented in collecting about network almanac 410 from each movement station nothing During the additional information of at least some transmitting set in line transmitter, information can be with obtaining additional reference point It is refined and becomes more accurate.Such as, the first movement station can report the position of specific wireless transmitter.The Two movement stations can report the slightly different with the position that the first movement station is reported of this specific wireless transmitter Position.In the case of only the two reference point, it is likely difficult to determine this specific nothing in this particular example The fairly accurate position of line terminal.But, if can be from additional mobile station or in the moment after a while with not Co-located obtains additional report from the first and second identical movement stations, then can obtain this particular transmitter More accurately estimating of position.

Fig. 5 is the schematic diagram of illustrated example layering transmitting set almanac 500.For this example, layering knot Structure can store the information about WLAN.But, in the following discussion, also discuss relate to cellular radio lead to The element of letter, because shown laminated tissue can be used for any kind of network.As it has been described above, movement station may Because size and cost consider, there is the limited capacity for storing information at least in part.Generally, including Many information in base station almanac are to repeat, and this is owing to for wireless communication system (such as cellular system) Great majority or whole sector of interior great majority or all transmitter store similar parameters.Have with each transmitter The information closed can be stored as flat list, the most such as, for all individual fan of all individual transmitters District, the Proprietary Information of each transmitter is stored in independent entry.Accordingly, because the weight of transmitter information Renaturation feature, and due to movement station limited for storing the capacity of this type of information, by reducing the non-of information It is useful that necessity repeats more efficiently to store transmitter information in base station almanac.

In one aspect, the information of base station almanac can use laminated tissue to store.Laminated tissue can include number Individual layer.In one example, the top stem that includes, and lowermost layer can include access point identity layer 550 (in the case of the wireless communication systems such as such as WLAN332), or for such as cellular network 334 Deng wireless communication system, lowermost layer can include sector mark (SECTOR_ID) layer.Public information can quilt It is stored in stem rather than repeats to be public information across all or almost all sector.With this side Formula, the single instance of public information can be stored in stem, and without in all access points or sector entry In repeat this information.On the one hand, it should be appreciated that the information being stored in stem is applicable to access point identity or fan All entries of district's label layer, unless marked any in the individual entries of access point identity or sector mark layer Exception.Generally, the information repeated in the considerable entry of normal base station almanac can be deposited by any script Storing up in the single entry in the high level of layering base station almanac and store, the most greatly reducing originally will be in routine The amount repeated present in base station almanac.

On the one hand, layering transmitting set almanac 500 can represent be stored in such as BSA server 180 or BSA on 350 BSA server such as grade.On the other hand, layering transmitting set almanac 500 can represent want Send movement station the BSA information being stored in this movement station to.A kind of wireless communication networks of exemplary types Network includes CDMA (CDMA) network.Cdma network can include can be with the ID parameter of laminated tissue. Therefore, the almanac of the given collection of transmitters of conveying is probably useful in a hierarchical manner.Similarly, it is used for The ID parameter of WLAN332 can be by layered mode tissue.The example described for Fig. 5, is layered nothing Line transmitter almanac 500 can include multiple layering, such as header layers 510, can include one or more system System banner (SID) layer 520 of label layer entry, one or more network identity layer entry can be included Network identity layer (NID) 530, area identification layer 540(are in the case of wlan) or cellular cell Label layer (in the case of cellular network) and access point identity layer (in the case of wlan) or Sector mark layer (in the case of cellular network).For the example of Fig. 5, SID layer 520 includes a pair Entry SID521 and SID522, NID layer 530 includes entry NID531 and NID532, and region is marked Know layer 540 and include area entries 541-544, and access point identity layer 550 includes access point entry 551-579 (skipping even number, see as in Fig. 6).As an example, NID entry 531 and 532 can include One or more network identifiers, these network identifiers can identify one or more network provider.One side Face, area entries 541-544 can include one or more area identification value or one or more realm identifier, And access point entry 551-579 can include one or more access point identity value.Certainly, wireless for layering The example tissue that transmitter almanac 500 is described is only an example, and the scope of subject content required for protection The most unrestricted.Such as, the scope of subject content required for protection is not limited to for layering nothing The specific quantity of line transmitter almanac 500 description or the layer of type.Similarly, in theme required for protection The scope held is not limited to be layered described quantity or the bar of type in each layer of transmitting set almanac 500 Mesh.

On the other hand, some networks do not utilize layered coding scheme.The most for example those can conduct The WAP of the part of WLAN332 can place their position with self-organizing according to its owner Mode is organized.WAP almanac is likely to the transmitter because of greater number but more dense.Will The transmitting set being included in the BSA subset of movement station to be sent to (such as movement station 322) can be extremely It is at least partly based on its position in the geometry region specified by movement station to be chosen, or passes through Region is specified to include that its area of coverage is chosen.On the one hand, the granularity of provided information is in district interested The center in territory is bigger than at separate location.Permission movement station 322 is connect by this from BSA server 350 It is received in movement station 322 and is likely to there is the BSA of greater density and accuracy by being in place therein in a short time Information, but there is the almanac information of more broad area simultaneously.Such as, movement station 322 can be at it to BSA The request of server 350 is specified near the most intensive almanac himself estimating position, and also may specify The more rough almanac information of further distance.

Fig. 6 is the ground of the example location being depicted on map 600 the multiple transceivers being marked as stain The diagram of Figure 60 0.For the example of Fig. 6, map 600 depict be distributed in each position access point 601, 603,605,607,609,611,613,615,617,619,621,625,627 and 629.One Aspect, access point 601-629 can include WLAN access point, but the model of subject content required for protection Enclose and be not limited in this respect.Map 600 further depict airport 602, highway 620, hospital 606, does Public bombyx Botryticatus 619, car service station 608 and office building 604.Map 600 further depict labeled The entrance on airport 602 is arrived in multiple streets of the south-north direction for 664,666,668,672 and offer Street 662.Equally, depict east-west some streets, be marked as 651,653,655,657, 659 and 661.Certainly, map 600 and each ingredient thereof are only claimed merely for convenient discussion The purpose of each side of subject content and present.Map 600 and ingredient thereof are not intended to describe such as to build Build, truly or accurately arrangement or the general layout of street or access point.

As set forth above, it is possible to each access point being based at least partially in multiple access point is to movement station 322 Future navigation operation expection contribution come to movement station (such as movement station 322) provide almanac information son Collection.Expection contribution can be such as based on expection contribution margin and be also based on making one for each access point Or the probability that multiple signal is obtained by movement station 322.In addition, on the one hand, for each WAP The probability that one or more signal is obtained by movement station 322 can be based at least partially on individuality and connect The adjacency of the current location of access point and movement station 322.For example, it is assumed that movement station 322 estimates that its position exists Position " A " at hospital 606 between street 657 and 659 on map 600 Shang street 664. On the one hand, movement station 422 can have enough data storage capacities and preserves about access point 601-629's Almanac information.But, in more real environment, the region described in such as map 600 potentially includes The access point more much more than the access point described.Such as, each in office building 604 and 610 can To have multiple access point in this building.Many family, office, retailing facility, restaurants etc. can be wrapped Containing access point to provide Wi-Fi to access to resident family, lessee, client, employee, traveller etc..But, For illustrative purposes, for relating to the example of Fig. 6, it is assumed that access point 601-629 represents to have and is available for depositing All access points of the storage known or estimated information in almanac.

For relating to Fig. 6 and the example of map 600, movement station 322 may have access to layering transmitting set almanac 500.For one or more examples, the region described in map 600 can correspond to Fig. 5 and described Layering transmitting set almanac 500 area entries 541.Access point 601-629 is wireless with layering respectively Access point entry 551-579 in the access point identity layer 550 of transmitter almanac 500 is associated.Note, Access point entry 551-579 of access point identity layer 550 is associated with area entries 541.On the one hand, district Territory entry 541 can include access point entry 551-579 is designated the information being associated with area entries 541. Area entries 541 can include that for being reversely relevant to all of area entries 541 or most of access point be public Common information.Such as, if all access points are all compatible with IEEE801.11g standard, then area entries 541 can store this information, and this information will be without being stored in each access point entry 551-579.

Return wherein movement station 322 and be positioned at the example of the position " A " at hospital 606, can be by such as downloading Which in multiple access point 601-629 the network entities such as manager 450 or BSA server 350 make about A little access points make it possible to the judgement that one or more signal is obtained by movement station 322 in the near future.For This example, this judgement can be based at least partially on the estimated position of each access point and movement station 322 Adjacency.On the one hand, on range, access point closest to position " A " will have so that signal is in the recent period The interior bigger probability obtained by movement station 322.On the other hand, may be made that about access point 601-629 In which access point on range closest to the judgement of position " A ", and be at least partially in response to this One judge, can by be determined to be on range closest to going through that those access points of position " A " are associated Letter breath is transferred to movement station 322.In this way, when movement station 322 is when position " A " is mobile, close The almanac information of those access points likely observed in movement station 322 is already stored at movement station 322 Place.For this example, access point 607,609 and 627 can be confirmed as making it possible to signal and be moved Stand 322 obtain.Certainly, in an actual realization, can relate to much more access point.On the other hand, may be used To periodically repeat the locking of the position to movement station 322, and can the most more be newly stored in movement station Almanac information at 322.

Another example technique above-mentioned can relate to be based at least partially on movement station 322 within the past period Each access point from multiple access points obtains the number of times of signal and determines making for each access point The probability that one or more signals are obtained by movement station 322.For this example, it is assumed that user one Friday Secondary go work with movement station 322, and it is further assumed that the path of this user working includes from east to west Street 653 travels through access point 621 and 625.Along same street from west when this user comes off duty Travel eastwards, also pass through access point 621 and 625.Therefore, for this simple examples, access point 621 Observed weekly at least 10 times by movement station 322 with 625.In addition, it is assumed that this user is once in a while along street 651 Advance.Therefore, movement station 322 will observe access point 615 once in a while.As a result, for this example, access Point 621 and 625 is confirmed as having the probability obtained by movement station 322 so that one or more signals, And the almanac information about those access points can be provided to movement station 322.Equally, although showing for this Example access point 615 is relatively close access point 625 in distance, but because movement station 322 is the most just observed Access point 615, so such as the almanac information about access point 615 can be not applied to movement station 322.

As another example, make one or many for determining for each access point in multiple access points The technology of the probability that individual signal is obtained by movement station 322 can include being based at least partially on individual access point with The adjacency of the history route of movement station 322 determines this kind of probability.Return to map 600, it is assumed that use Advance along highway 620 with movement station 322 once in a while and move from south orientation backlands in family.For this letter Single example, although this is not likely to be recurrent, but sees successively at each time or the most each time movement station When observing access point 603,605 and 607, movement station 322 all continues to observe access point 609,611 and 613.Therefore, such as the Internet resources such as download manager 450 or BSA server 350 can determine shifting Dynamic station 322 is along history route and advances and have this movement station and will observe the possibility of access point along this route The almanac information about the access point along this history route is provided to movement station 322 during property.

Another example as history route, it is assumed that most of time movement station 322 observes access point 605 Then observe access point 601(to represent to airport 602 to advance), movement station then finds that oneself is at old gold International airport, mountain (SFO).For this example, if download manager 450 has determined movement station 322 Continuous Observation is to access point 605 and 601, then download manager can provide about SFO to movement station 322 Almanac information so that movement station 322 final really at SFO time this movement station 322 at it Almanac information needed for middle storage, and navigate and can immediately begin to when arriving.

On the other hand, one or more letter is made for each access point in multiple access points for determining The technology of number probability obtained by movement station 322 can include being based at least partially on individual access point and movement Stand 322 prediction route adjacency to determine this kind of probability.On the one hand, it was predicted that route can at least portion Divide ground one or more history route based on movement station 322, but subject content required for protection is this side Face is unrestricted.On the other hand, as it has been described above, probability can be based at least partially on movement station 322 is propped up The Radio Access Type held.Probability may also be based at least in part on: it is various that movement station 322 is supported The Radio Access Type that currently enabled on the utilization rate of Radio Access Type, movement station 322 or May also be based at least in part on individual transmitting set within a period of time makes signal be moved by multiple other Stand obtain number of times, to such as download manager 450 network entity such as grade, other movement station the plurality of reports that it is seen Examine.Certainly, these only can be used for determining for each transmitting set in multiple transmitting sets Make the example of the information of the probability that one or more signal obtained by movement station, and required for protection The scope of subject content is not limited in this respect.

In examples described herein, movement station (such as movement station 322) is described as taking to BSA BSA information asked by business device 350.In response to the request received from movement station 322, BSA server 350 configure suitable information and deliver it to movement station 322.But, there are many changes of these examples Shape, because there being the various technology for transmitting BSA information to movement station 322.In some cases, institute The particular type of air interface can be depended, at least partially, on by technology.In some air interfaces, launch real Body can also store and forward the BSA information of their own or the BSA information of its neighboring entities.Such as, referring to Fig. 1, base station 132 can store BSA information, and can receive from when the request of movement station 150 This BSA information is transmitted to movement station 150 at least partially.Base station 132 can show according to above-mentioned Example is compressed or adds confidential information.On the other hand, BSA information can be asked by base station 132 granting movement station Certification movement station 150 before asking.

It addition, on the one hand, base station 132 can periodically in range and have and base station 132 to place The ability of communication and the movement station broadcast BSA information of authority.Can presence or absence from movement station or This type of transmission is carried out in the case of the prompting of another network entity.On the other hand, can carry to movement station 150 The URL (URL) of network site of BSA information can be obtained from it for pointing to movement station 150. For the example in Fig. 1, network entity can include BSA server 180.But, as depicted in figure 3 , as another example, movement station also can obtain database information from the outside almanac source 360 of third party.? On the one hand, movement station (such as movement station 324) can be from the outside almanac of the third party providing on-demand BSA to update Source 360 booking service.Or, on the other hand, such as, the outside almanac source 360 of third party can be periodically Ground provides and updates, or updates whenever providing when generation demand because such as system reconfigures.

As discussed previously, in one aspect, BSA server 350 can receive from third-party BSA Information.On the other hand, BSA server 350 or the storage such as the most one or more base station or access point Any other network entity of BSA information can receive the BSA information collected from one or more movement stations. The information collected from movement station can include the such as information of collection during location estimation operates.The opposing party Face, some movement stations can store them and receive from it the data base of the transmitter of signal.On the one hand, This data base can include the particular community about those transmitters, the most for example positional information, carrier frequency Rate etc..This information may be supplied to movement station by wireless network, or can be derived letter by movement station self Breath.Regardless of source, in the exploitation and maintenance of the BSA that can be used by the movement station in given area, Collected information can be desired.

On the other hand, it may be desirable to movement station reports specified amount information to base station almanac server, with such as Exchange more complete BSA information.Movement station is collected and the information of report can include that adjoint relevant position is indefinite Property a series of positions, and may also include movement station from those position detections to transmitter be found belong to Property.These attributes such as can include transmitter identification information, and signal(-) carrier frequency, relatively or definitely believes The timing of number intensity, colour coding, gap or any other potentially contribute to BSA server and map individual transmitter The area of coverage for information about.These attributes may also include code-phase or some standard timing sources of each transmitter Timing relationship between (such as SPS time) and one or more framing structure receiving signal.

Fig. 7 is to incite somebody to action movement station for being based at least partially on one or more corresponding transmitting set The one or more expection contributions operated of navigating determine goes through the transmitting set being sent to movement station The flow chart of the instantiation procedure of the subset of letter breath.At frame 710, can be based at least partially on multiple wireless Each transmitting set in transmitter future of movement station is navigated operation expection contribution value and for One or more signal that makes of each transmitting set in multiple transmitting sets is obtained by movement station Probability determines that the future of movement station is navigated by each transmitting set in the plurality of transmitting set and grasps The expection contribution made.On the one hand, as non-limiting example, it is contemplated that contribution margin can based on range capability, Expection measures or observes accuracy, overlay area size or previously navigates in operation about particular transmitter The statistical data of importance.For determining that the one or more signal that makes for each transmitting set is moved The example of the possible technology of the probability that dynamic station obtains is discussed above, and can include partly Adjacency based on individual transmitter with the current location of movement station determines this kind of probability, or at another Aspect, this kind of probability can be based at least partially on movement station and obtain letter in the past from individual transmitting set Number frequency.As additional example, probability can be based at least partially on individual transmitter and movement station The adjacency of history route, or on the other hand, this kind of probability can be based at least partially on movement station institute The Radio Access Type supported.Probability may also be based at least in part on the various nothings being supported movement station Line is electrically accessed on the utilization rate of type, movement station the Radio Access Type currently enabled or also can be extremely Being at least partly based within a period of time individual transmitting set makes signal be obtained by other movement stations multiple Number of times, other movement station the plurality of to the such as network entity such as download manager or BSA server report It is observed.As other example, probability can be based at least partially on the pre-of individual transmitter and movement station Whether adjacency or the movement station of surveying route are authorized to be communicated by transmitting set.

At frame 720, can be based at least partially on determined by the expection contribution of each transmitting set come really Determine the subset of transmitting set.On the one hand, determine that the subset of transmitting set may include determining whether for each nothing Whether the probability of line transmitter exceedes the threshold value being pre-selected.At frame 730, can identify about determined by The almanac information of the subset of transmitting set.Example according to theme required for protection can include frame Whole or the most less or more frame of 710-730.Additionally, the order of frame 710-730 is only It is sample order, and the scope of theme required for protection is not limited in this regard.
