## Title
Geographic redundancy determination for time based location information in a wireless radio network

## Abstract

Determining levels of geographic redundancy among radios of a wireless radio network is disclosed. The level of geographic redundancy for a radio can affect the determination of location information for a user equipment (UE) on the wireless radio network. The disclosed subject matter can be employed in conjunction with timed fingerprint location (TFL) technologies to facilitate selection of radios employed in determining time values for TFL location determination. Levels of geographic redundancy can be employed to rank or order radios of a wireless radio network so as to reduce the likelihood of using geographically redundant radios in location determination. Further, rules can be selected to adjust threshold values and equations employed in determining the levels of geographic redundancy. Moreover, rules can be selected to apply boundary conditions to reduce the number of determinations formed for a set of radios of the wireless radio network.

TECHNICAL FIELD
The disclosed subject matter relates to a determining geographic redundancy in a wireless radio network, e.g., determination of geographically redundant radios employed in determining time based location information in a wireless radio network.
BACKGROUND
In mobile equipment networks, locating user equipments (UEs) can provide valuable additional benefits to users and opportunities for additional or improved services. Locating UEs in a wireless network can facilitate providing location-centric services or information in relation to the UE, such as E911 services, mapping services, or traffic information services, among many others. Additionally, UE location information can be employed to improve network performance, to troubleshoot networks, by law enforcement, to aggregate valuable demographic information, or nearly a limitless number of other uses. Network timing delays include site timing delay in the wireless signal path among radio component(s) at the wireless base station and a sector antenna. Network timing delays further include delays that can arise from various mismatches (e.g., impedance mismatch) among electronic elements and components, stray capacitances and inductances, length of the antenna(s) cable(s) in base station(s); tower height of base station, signal path scattering, or “signal bounces,” such as multipath or strong reflections, and the like. Propagation delay between a UE and a NodeB is conventionally assumed to be negligible with respect to timing delay. However, depending on the architecture of the serving base station and covered sector antenna(s), signal propagation delay can be non-negligible, particularly in distributed antenna systems and low-power wireless radio cells and cause error in UE location determinations for traditional methods.

DETAILED DESCRIPTION
The subject disclosure is now described with reference to the drawings, wherein like reference numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the subject disclosure. It may be evident, however, that the subject disclosure may be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to facilitate describing the subject disclosure.
By way of brief background, a network locating system (NELOS) can employ timed fingerprint location (TFL). TFL, as disclosed in U.S. patent application Ser. No. 12/712,424, can facilitate determining location information based, in part, on receiving timing measurements between at least a pair of wireless network radios and a device. In an aspect, determining location information in a NELOS-enabled system, e.g., a system employing TFL, benefits from employing one or more timing measurements for a non-redundant radio link with a device, e.g., timing measurements associated with radio links between a NodeB site pair (NBSP) and a mobile device. Non-redundant radio links can generally employ non-redundant radios. A radio can be associated with a level of redundancy where, geographically, two or more radios are close enough to each other that they result in highly similar timing measurements for use in location information determination. In an aspect, while radios that are close together can be employed in determining location information, they generally will have greater error in a location determination information that radios that are not geographically redundant. As an example, radio pairs, e.g., NBSPs, with geographically redundant radios in a TFL-enabled system can yield results from a query that are highly similar and thus, determining an intersection of those query results can have a lower level of confidence than would be associated with query results from NBSPs with non-redundant radios.
A NELOS can employ TFL technologies that can include location information or timing information as disclosed herein and as further disclosed in more detail in U.S. Ser. No. 12/712,424 filed Feb. 25, 2010, which application is hereby incorporated by reference in its entirety. TFL information can facilitate access to location information for a mobile device, e.g., a UE. TFL information can be information from systems in a timed fingerprint location wireless environment, such as a TFL component of a wireless telecommunications carrier. As a non-limiting example, UEs, including mobile devices not equipped with a GPS-type system, can be associated with TFL information, which can facilitate determining a location for a UE based on the timing information associated with the UE.
In an aspect, TFL information can include information to determine a differential value for a radio, e.g., a NodeB site pair, and a bin grid frame, as disclosed in more detail in incorporated U.S. Ser. No. 12/712,424. A centroid region (possible locations between any site pair) for an observed time value associated with any NodeB site pair (NBSP) can be calculated and can be related to the determined value (in units of chip) from any pair of NodeBs. When UE time data is accessed, a value look-up can be initiated (e.g., a lookup for “DV(?,X)” as disclosed in more detail in the application incorporated herein by reference). Relevant NBSPs can be prioritized as part of the look-up. Further, the relevant pairs can be employed as an index to lookup a first primary set. As an example, time data for a UE can be accessed in relation to a locating event in a TFL wireless carrier environment. In this example, it can be determined that a NBSP, with a first reference frame, be used for primary set lookup with the computed DV(?,X) value as the index. This can return, for example, a set of bin grid frame locations forming a hyperbola correlating to the radios of the NBSP. A second lookup can then be performed for an additional relevant NBSP, using the same value DV(?,X), as an index into the data set. Continuing the example, the returned set for the look up with second NBSP can return a second set of bin grid frames. Thus, the UE is likely located in both sets of bin grid frames. Therefore, where the UE is likely in both sets, it is probable that the location for the UE is at an intersection of the two sets. Additional NBSPs can be included to further narrow the possible locations of the UE by providing additional intersections among relevant bin grid sets. As such, employing TFL information for location determination is demonstrably different from conventional location determination techniques or systems such as GPS, AGPS, triangulation or multilateration in wireless carrier environments, near field techniques, or proximity sensors.
In an embodiment, a system can include a processor and memory. The processor can facilitate the execution of computer-executable instructions stored on the memory. The processor can facilitate execution of the computer-executable instructions to determine a level of geographic redundancy for a first radio of a wireless network. The determined level of geographic redundancy can be based on geographic information relating to a set of radios, of the wireless network, including the first radio.
In another embodiment, a method can include determining, by a system including at least one processor, a level of geographic redundancy for a first radio of a wireless network. The determining of the level of geographic redundancy can be based on geographic information relating to a set of radios, of the wireless network, including the first radio.
In a further embodiment, a method can include receiving, by a system including at least one processor, predetermined information relating to levels of geographic redundancy for a set of radios of a wireless network. The method can further include determining, by the system, location information based on information relating to a selected radio. The selection of the radio can be based on the predetermined information relating to the levels of geographic redundancy for the set of radios of the wireless network.
To the accomplishment of the foregoing and related ends, the disclosed subject matter, then, comprises one or more of the features hereinafter more fully described. The following description and the annexed drawings set forth in detail certain illustrative aspects of the subject matter. However, these aspects are indicative of but a few of the various ways in which the principles of the subject matter can be employed. Other aspects, advantages and novel features of the disclosed subject matter will become apparent from the following detailed description when considered in conjunction with the drawings.
FIG. 1 is an illustration of a system 100, which facilitates adaptive calibration in accordance with aspects of the subject disclosure. System 100 can include radio geographic information (RGI) component 110 that can facilitate access to geographic information related to radios of a wireless network. In an aspect, wireless network carriers know the location at which the radios of the wireless network are placed as part of deploying the physical resources of a wireless network. In certain embodiments, geographic information for wireless network radios can be in the form of geographic information system (GIS) information. A geographic information system can be a system designed to handle types of geographical data. At a very basic level, GIS can be a mélange of cartography, statistical analysis, and database technology. RGI component 110 can enable, in some embodiments, interaction with GIS information. As a non-limiting example, RGI component 110 can facilitate receiving geographic position information for radio resources of a wireless network carrier by way of a coupling with the carrier's GIS system.
System 100 can further include rule component 120 that can facilitate access to one or more rules associated with determining a level of geographic redundancy. In an aspect, rules can relate to definition of, or characterization of geographic information as it relates to geographic redundancy. As an example, a rule can include one or more predetermined threshold values that correspond to different levels of redundancy. In a further aspect, rules can relate to boundary conditions related to determinations of geographic redundancy. As an example, in large sets of radios, a boundary condition can limit determining redundancy to radios within a predetermined distance, selected region, selected status, etc. Rule component 120 can also receive rule updates to facilitate changes to rule sets that affect the determination of levels of geographic redundancy.
System 100 can further include geographic redundancy component 130 to facilitate determination of a level of geographic redundancy. Geographic redundancy component 130 can be communicatively coupled to RGI component 110 to facilitate receiving geographic information for a set of radios associated with a wireless network. Geographic redundancy component 130 can also be communicatively coupled to rule component 120 to facilitate receiving at least a rule associated with determining a level of geographic redundancy for the set of radios associated with the wireless network.
In an aspect, geographic redundancy component 130 can determine a level of geographic redundancy. A level of geographic redundancy can be binary, e.g., redundant or not redundant, or can relate to a plurality of levels of redundancy, e.g., highly redundant, moderately redundant, slightly redundant, not redundant, etc. As an example, a determination of ‘highly redundant’ can be associated with not using the radio in location determination, while a determination of ‘slightly redundant’ can be associated with using the radio for location determination only when it is also a well calibrated radio. Additionally, a level of geographic redundancy can be employed to rank or order radios, or as a factor in other ranking or ordering techniques, etc. As an example, the higher the level of geographic redundancy, the lower the radio can be ranked for selection in determining location information. Continuing the example, other factors, such as calibration confidence, etc., can be associated with increasing the ranking of the radio for use in determining location information.
In a further aspect, the determined level of geographic redundancy can be employed to update radio information. Wherein the geometry of wireless network radios is known, the geographically redundant radios can be determined and the information can then be associated with the radios such that the information is predetermined with respect to determining location information based on timing information relating to the radios of the wireless network. This can facilitate selection of radios that meet predetermined ranking criteria associated with a predetermined level of geographic redundancy. As an example, a UE can be associated with a set of radio pairs facilitating a TFL information determination, the set including at least a pair of radios with a predetermined level of geometrically redundancy. In light of the predetermined level of redundancy, the exemplary TFL information determination can be based on radio pairs of the set of radios with lower levels of geometric redundancy to increase an overall level of confidence in the determined location information.
In a further aspect, geographic redundancy component 130 can determine levels of geometric redundancy for some, all, or no radios in a set of radios associated with RGI received by way of RGI component 110. In an embodiment, the selection of a subset of radios from a set of radios for which RGI is available can be a form of bounding. Bounding can allow, for example, predetermination of a level of geometric redundancy for radios within a predetermined distance from each other, etc. This can significantly reduce the number of determinations that are made in large sets of radios, e.g., determinations of radio sets for regions of a wireless network, etc.
FIG. 2 is a depiction of a system 200 that can facilitate determining a level of geographic redundancy in accordance with aspects of the subject disclosure. System 200 can include RGI component 210 that can facilitate access to geographic information related to radios of a wireless network. RGI component 210 can enable, in some embodiments, interaction with GIS information.
RGI component 210 can be communicatively coupled to radio information store 212. Radio information store 212 can be a store of information relating to a radio of a wireless network of radios. In some embodiments, radio information store 212 can comprise part of a carrier's GIS. Radio information store 212 can warehouse information about radios including geographic information, levels of geographic redundancy, radio identification, radio timing values, radio calibration information, or nearly any other type of information relative to a radio of a wireless network. Radio information store 212 can receive updates to the radio information as a radio update, e.g., information relating to a new radio, removal of a radio, updating a radio information, etc.
System 200 can further include rule component 220 that can facilitate access to one or more rules associated with determining a level of geographic redundancy. Rule component 220 can include rule criteria component 222. In an aspect, rules can relate to definition of, or characterization of geographic information as it relates to geographic redundancy. As an example, a rule can include one or more predetermined threshold values that correspond to different levels of redundancy. Criteria for rules can be received by way of rule criteria component 222. As an example, an equation for determining a level of geographic redundancy can be received by way of rule criteria component 222. As another example, a rule for determining a level of geographic redundancy can be based on predetermined threshold values that can be received by way of rule criteria component 222.
Rule component 220 can further comprise boundary condition component 224. Boundary condition component 224 can receive information relating to a bounding condition. Rules can include boundary conditions related to determinations of geographic redundancy. As an example, in large sets of radios, a boundary condition can limit determining redundancy to radios within a predetermined distance, selected region, selected status, etc. Rule component 220 can also receive rule updates to facilitate changes to rule sets that affect the determination of levels of geographic redundancy.
System 200 can further include geographic redundancy component 230 to facilitate determination of a level of geographic redundancy. Geographic redundancy component 230 can be communicatively coupled to RGI component 210 to facilitate receiving geographic information for a set of radios associated with a wireless network. Geographic redundancy component 230 can also be communicatively coupled to rule component 220 to facilitate receiving at least a rule associated with determining a level of geographic redundancy for the set of radios associated with the wireless network.
In an aspect, geographic redundancy component 230 can determine a level of geographic redundancy. Determinations of a level of geometric redundancy can be made by determination component 232 and can be based on a rule received by way of rule component 220 and RGI by way of RGI component 210. A level of geographic redundancy can be employed to rank or order radios, or as a factor in other ranking or ordering techniques, etc.
In a further aspect, a determined level of geographic redundancy can be employed to update radio information. Designation component 234 can facilitate designation a level of geometric redundancy by facilitating access to information relating to the determined level of redundancy. Wherein the geometry of wireless network radios is known, geographically redundant radios can be determined and the information can then be associated with the radios such that the information is predetermined with respect to determining location information based on timing information relating to the radios of the wireless network. Thus, predetermined levels of geometric redundancy can be determined, at determination component 232, and information about said levels can be received, by way of designation component 234, for storage at radio information store 212 by way of RGI component 210. This can facilitate selection of radios that meet predetermined ranking criteria associated with a predetermined level of geographic redundancy.
In another aspect, geographic redundancy component 230 can determine levels of geometric redundancy for some, all, or no radios in a set of radios associated with RGI received by way of RGI component 210. In an embodiment, the selection of a subset of radios from a set of radios for which RGI is available can be a form of bounding. Bounding can allow, for example, predetermination of a level of geometric redundancy for radios within a predetermined distance from each other, etc. This can reduce the number of determinations that are made in large sets of radios.
Moreover, detection component 236 can determine if there have been changes to information relating to a set of radios, e.g., by communicative coupling with radio information store 212 by way of RGI component 210. Changes can include addition of a new radio, e.g., a new radio being installed in a wireless network, etc., deletion of a radio, or updates to an existing radio. Where changes in radios occur, the RGI and geometric redundancy can also be impacted. As such, a detected change can allow for an automatic redetermination of geometric redundancy information. Further, the automatic redetermination can be for part, all, or none of a radio set based on which radios are detected as having changed. As an example, where a single radio is added, this can influence a relative few determined levels of geometric redundancy. As another example, where a new region of wireless network is added, e.g., by way of acquiring another wireless carrier, etc., it can be more prudent to re-determine all or most of the geometric redundancy determinations.
FIG. 3 illustrates a system 300 that facilitates determining a level of geographic redundancy for a timed fingerprint locating enabled system in accordance with aspects of the subject disclosure. System 300 can include RGI component 310 that can facilitate access to geographic information related to radios of a wireless network. In certain embodiments, geographic information for wireless network radios can be in the form of GIS information. RGI component 310 can enable, in some embodiments, interaction with GIS information. In an aspect, RGI component 310 can be communicatively coupled to radio information store 312. Radio information store 312 can be a store of information relating to a radio of a wireless network of radios. In some embodiments, radio information store 312 can comprise part of a carrier's GIS. Radio information store 312 can warehouse information about radios including geographic information, levels of geographic redundancy, or nearly any other type of information relative to a radio of a wireless network. Radio information store 312 can receive updates to the radio information as a radio update.
System 300 can further include rule component 320 that can facilitate access to one or more rules associated with determining a level of geographic redundancy. In an aspect, rules can relate to definition of, or characterization of geographic information as it relates to geographic redundancy. In a further aspect, rules can relate to boundary conditions related to determinations of geographic redundancy. Rule component 320 can also receive rule updates to facilitate changes to rule sets that affect the determination of levels of geographic redundancy.
System 300 can further include geographic redundancy component 330 to facilitate determination of a level of geographic redundancy. Geographic redundancy component 330 can be communicatively coupled to RGI component 310 to facilitate receiving geographic information for a set of radios associated with a wireless network. Geographic redundancy component 330 can also be communicatively coupled to rule component 320 to facilitate receiving at least a rule associated with determining a level of geographic redundancy for the set of radios associated with the wireless network.
In an aspect, geographic redundancy component 330 can determine a level of geographic redundancy. A level of geographic redundancy can be employed to rank or order radios, or as a factor in other ranking or ordering techniques, etc. In an aspect, the determined level of geographic redundancy can be employed to update radio information. This can facilitate selection of radios that meet predetermined ranking criteria associated with a predetermined level of geographic redundancy.
In a another aspect, geographic redundancy component 330 can determine levels of geometric redundancy for some, all, or no radios in a set of radios associated with RGI received by way of RGI component 310. In an embodiment, the selection of a subset of radios from a set of radios for which RGI is available can be a form of bounding. Bounding can allow, for example, predetermination of a level of geometric redundancy for radios within a predetermined distance from each other, etc. This can significantly reduce the number of determinations that are made in large sets of radios, e.g., determinations of radio sets for regions of a wireless network, etc.
System 300 can further comprise timed fingerprint location (TFL) component 340. TFL component 340 can be communicatively coupled to radio information store 312 to receive predetermined geographic redundancy information stored thereon by way of geographic redundancy component 330. As such, geographic redundancy information can be employed in selection of radio pairs employed in determining location information by way of a TFL system, e.g., NELOS. As an example, a UE can be associated with a set of radio pairs facilitating a TFL information determination, the set including at least a pair of radios with a predetermined level of geometrically redundancy. In light of the predetermined level of redundancy, the exemplary TFL information determination can be based on radio pairs of the set of radios with lower levels of geometric redundancy to increase an overall level of confidence in the determined location information.
FIG. 4 is an illustration of an exemplary system 400 having a level of geographic redundancy in accordance with aspects of the subject disclosure. System 400 can include a set of radios, the set including radios 410, 420, 430, and 440. The set of radios can comprise part of a wireless network. Timing signals associated with radio links between the radios of the set and UEs can facilitate determination of location information, e.g., a NELOS or TFL-enabled wireless network. The distance between radio 410 and radio 420 can be distance 460. Similarly, the distance between radio 410 and radio 430 can be distance 450. Likewise, the distance between radio 420 and radio 430 can be distance 470.
In an aspect, UEs can employ radio pairs, such as the pair 410/420 and the pair 410/430, for determination of location information, such as by way of TFL techniques. However, use of radio pairs 410/420 and 410/430 can result in a degree of error where radios 420 and 430 can have a level of geometric redundancy. As an example, where radio 420 and radio 430 are close geometrically with respect to radio 410, the resulting TFL lookups in a TFL-enabled system, can return similar sets of bins that can result in an inaccurate union between the returned sets of bins and a widening effect on the probable location of a UE. By predetermining that radio 420 and radio 430 have a level of geometric redundancy with regard to radio 410, the selection of radio pairs for TFL lookup using both of the redundant radios can be deprioritized, for example, in favor of using just one of the geometrically redundant radios.
In an exemplary embodiment, the level of geometric redundancy can be binary. The exemplary embodiment can further be based on distance 450 and 460 being within, for example, 10% of each other. Then, where distances 450 and 460 are within 10% of each other, the distance 470 can be further evaluated to determine redundancy. As an example, where distance 470 is less than 10% of the average of distances 450 and 460, then radios 420 and 430 can be determined to be geometrically redundant with regard to radio 410.
In another exemplary embodiment, the same exemplary threshold values and rules can be employed and be applied with regard to radios 440, 420, and 430. As such, where distances 490 and 480 are within 10% of each other, then distance 470 can be evaluated to determine geometric redundancy. Thus, where distance 470 is less than 10% of the average of distances 480 and 490, radios 420 and 430 can be geometrically redundant with regard to radio 440. As can be observed, where radio 410 is much further away from radios 420 and 430 than radio 440, for the exemplary criteria, radios 420 and 430 are more likely to be geometrically redundant with regard to radio 410 than for radio 440.
The level of geometric redundancy information can be stored for the several radios, e.g., by way of radio information store, 212 or 312, etc. This predetermined geometric redundancy information can then facilitate selection of radio pairs that can be less affected by geometric redundancy when determining location information based on radio timing information.
It will be noted that the exemplary 10% value is arbitrarily selected to illustrate an example of the disclosed subject matter and that the disclosure is not so limited to that value or those near it. As further examples, the first determination of the difference between the long legs of the radio pair triangle, e.g., distances 460 and 450, etc., can be subject to any threshold value, such as, but not limited to, 1%, 10%, 50%, 90%, 100 meters, 2 chip, 5 msec, etc. Similarly, the determination of a level of geometric redundancy with regard to the short leg of the radio pair triangle, e.g., distance 470, etc., can be subject to any equation and/or threshold value, such as, but not limited to, distance 470 is greater than 1 meter but less than 100 meters; distance 470 is less than 2% of the sum of distances 460 and 450; distance 470 is less than 22% of the average of distances 490 and 480, etc.
FIG. 5 is an illustration of an exemplary system 500 having a level of geographic redundancy in accordance with aspects of the subject disclosure. System 500 can include a set of radios, the set including radios 510, 520, 530, and 570. The set of radios can comprise part of a wireless network. Timing signals associated with radio links between the radios of the set and a UE 502 can facilitate determination of location information, e.g., a NELOS or TFL-enabled wireless network.
Determination of a level of geometric redundancy can occur as disclosed herein. This predetermined level of redundancy can be stored and received to facilitate selection of radio pairs for determination of location information. Determination of location information can be by way of TFL-enabled techniques, e.g., NELOS. As an example, radios 520 and 530 can be predetermined to be geometrically redundant with regard to radio 510 and not geometrically redundant with regard to radio 570. As such, selection of radio pairs for location determination can be considerate of the predetermined geometric redundancy.
Continuing the example, if radio pair 510/520 and radio pair 510/530 are selected for determining location information by way of a TFL technique, lookup of the timing values of the pairs can result in exemplary probable bin locations defined by curved lines 540 and 550 respectively. As will be noted in the illustration of system 500, bin locations for 540 and 550 are highly similar and a union of the two sets of bin locations could result in a probable location between area 560 and 562 along curves 540 or 550. This result can be less accurate, due to employing geometrically redundant radio pairs, than a TFL lookups with non-redundant radio pairs.
As an example of selecting non-redundant radio pairs, curved line 580 can represent the set of returned bin grid locations for an exemplary TFL lookup for radio pair 570/530. As such, for determining location information for UE 502, it can be determined that employing radio pair 510/520 in conjunction with radio pair 510/530 is lower priority because of a predetermined geometric redundancy. Therefore, either radio pair 510/520 or radio pair 510/530 can be employed with another non-redundant radio pair, such as radio pair 570/530. This can result in determining the probable location to be at the union of either curve 540 or 550 with curve 580. Given that the curves are much less similar, the union can be more distinct and can have less ambiguity as to the probable location of UE 502 at 582, rather than between 560 and 562 as discussed earlier in the example.
In a further aspect, treatment of radio pairs demonstrating a level of geometric redundancy can include exclusion of one of the redundant radio pairs as disclosed in the above example. Another treatment option can include exclusion of both pairs in favor of purely non-redundant radios. A further treatment can include ‘averaging’ the redundant radio pairs, e.g., an ‘average’ of radio 520 and radio 530 with regard to radio 510 can return an average of the curves 540 and 550. Yet another treatment can include selecting one or more of the redundant radios based on another criteria in light of the radios being redundant, for example, where the radios are redundant but have the most recent calibration they can still be selected over other non-redundant but poorly calibrated radios, though the selection techniques are beyond the scope of the present disclosure.
In view of the example system(s) described above, example method(s) that can be implemented in accordance with the disclosed subject matter can be better appreciated with reference to flowcharts in FIG. 6-FIG. 8. For purposes of simplicity of explanation, example methods disclosed herein are presented and described as a series of acts; however, it is to be understood and appreciated that the claimed subject matter is not limited by the order of acts, as some acts may occur in different orders and/or concurrently with other acts from that shown and described herein.

Moreover, interaction diagram(s) may represent methods in accordance with the disclosed subject matter when disparate entities enact disparate portions of the methods. Furthermore, not all illustrated acts may be required to implement a described example method in accordance with the subject specification. Further yet, two or more of the disclosed example methods can be implemented in combination with each other, to accomplish one or more aspects herein described. It should be further appreciated that the example methods disclosed throughout the subject specification are capable of being stored on an article of manufacture (e.g., a computer-readable medium) to allow transporting and transferring such methods to computers for execution, and thus implementation, by a processor or for storage in a memory.
FIG. 6 illustrates aspects of a method 600 facilitating determining a level of geographic redundancy in accordance with aspects of the subject disclosure. At 610, radio geographic information (RGI) can be received. RGI can be related to radios of a wireless network. Whereas wireless network carriers know the location at which radios of a wireless network are placed as part of deploying the physical resources of a wireless network, RGI can include the geographic information of radios in the wireless network. In certain embodiments, geographic information for wireless network radios can be in the form of geographic information system (GIS) information. A geographic information system can be a system designed to handle types of geographical data.
At 620, a level of geographic redundancy can be determined based on the RGI received at 610. The determination of the level of geographic redundancy can be based on a rule. In an aspect, rules can relate to definition of, or characterization of geographic information as it relates to geographic redundancy. As an example, a rule can include a predetermined threshold value that corresponds to different levels of redundancy. In a further aspect, rules can relate to boundary conditions related to determinations of geographic redundancy. As an example, in large sets of radios, a boundary condition can limit determining redundancy to radios within a predetermined distance, selected region, selected status, etc.
A level of geographic redundancy can be binary or can relate to a plurality of levels of redundancy. Additionally, a level of geographic redundancy can be employed to rank or order radios, or as a factor in other ranking or ordering techniques, etc. In a further aspect, levels of geometric redundancy can be determined for some, all, or no radios in a set of radios associated with received RGI. In an aspect, the selection of a subset of radios from a set of radios for which RGI is available can be a form of bounding. Bounding can allow, for example, predetermination of a level of geometric redundancy for radios within a predetermined distance from each other, etc. This can significantly reduce the number of determinations that are made in large sets of radios, e.g., determinations of radio sets for regions of a wireless network, etc.
At 630, radio information can be updated based on the determined level of geographic redundancy. At this point, method 600 can end. A determined level of geographic redundancy can be employed to update radio information. This can facilitate selection of radios that meet predetermined ranking criteria associated with a predetermined level of geographic redundancy. As an example, a UE can be associated with a set of radio pairs facilitating a TFL information determination, the set including at least a pair of radios with a predetermined level of geometrically redundancy. In light of the predetermined level of redundancy, the exemplary TFL information determination can be based on radio pairs of the set of radios with lower levels of geometric redundancy to increase an overall level of confidence in the determined location information.
FIG. 7 illustrates a method 700 that facilitates determining a level of geographic redundancy in accordance with aspects of the subject disclosure. At 710, radio information can be received. Radio information can be for a set of radios (RS) including a first radio (RA) a second radio (RB) and a third radio (RC) of a wireless network. At 720, RGI can be determined from the radio information received at 710. RGI can be related to radios of a wireless network. RGI can include the geographic information of radios in the wireless network.
At 730, the difference between the distance from the first to the third radio and the distance from the second to the third radio can be determined, e.g., the difference between RA to RC (AC) and RB to RC (BC). In an aspect, this can be written in equation form as |AC−BC|. At 740, a distance between the first and second radio can be determined, e.g., the distance RA to RB (AB).
At 750, a level of geographic redundancy can be determined based on the distances determined at 730 and 740, e.g., AC, BC, and AB, etc. The determination of the level of geographic redundancy can be based on a rule. In an aspect, rules can relate to definition of, or characterization of geographic information as it relates to geographic redundancy. As an example, a rule can include a predetermined threshold value that corresponds to different levels of redundancy. In a further aspect, rules can relate to boundary conditions related to determinations of geographic redundancy. As an example, in large sets of radios, a boundary condition can limit determining redundancy to radios within a predetermined distance, selected region, selected status, etc.
A level of geographic redundancy can be binary or can relate to a plurality of levels of redundancy. Additionally, a level of geographic redundancy can be employed to rank or order radios, or as a factor in other ranking or ordering techniques, etc. In a further aspect, levels of geometric redundancy can be determined for some, all, or no radios in a set of radios associated with received RGI. In an aspect, the selection of a subset of radios from a set of radios for which RGI is available can be a form of bounding. Bounding can allow, for example, predetermination of a level of geometric redundancy for radios within a predetermined distance from each other, etc. This can significantly reduce the number of determinations that are made in large sets of radios, e.g., determinations of radio sets for regions of a wireless network, etc.
In an embodiment, the determination of a level of geographic redundancy can be based on a two-part determination. The first part of the determination can be based on the distance difference determined at 730. As a non-limiting example, a rule for the first part of the determination can be that to proceed to the second part of the determination the difference between the distance from the first to the third radio and the distance from the second to the third radio must be within 10%. The first part of the exemplary determination, in equation form, can be

The second part of the determination for the particular embodiment can be based on a comparison of the distance between the first and second radios and the determined distance from the first part of the determination. As a non-limiting example of the second part of the determination, inclusive of the results of the first part of the determination, in equation form, can be that geometric redundancy is present if, [2(AB)/((AC)+(BC))]≦0.1. It will be noted that the exemplary threshold values and exemplary equations are merely for illustration and are non-limiting. It will further be noted that other equations and threshold values can be employed without departing from the scope of the present subject matter. Moreover, the particular example of a two-part determination is non-limiting and other examples are not presented simply for clarity and brevity, though all such other techniques for determining a level of geographic redundancy are to be considered within the scope of the presently disclosed subject matter.

At 760, radio information can be updated based on the determined level of geographic redundancy. At this point, method 700 can end. A determined level of geographic redundancy can be employed to update radio information. This can facilitate selection of radios that meet predetermined ranking criteria associated with a predetermined level of geographic redundancy. As an example, a UE can be associated with a set of radio pairs facilitating a TFL information determination, the set including at least a pair of radios with a predetermined level of geometrically redundancy. In light of the predetermined level of redundancy, the exemplary TFL information determination can be based on radio pairs of the set of radios with lower levels of geometric redundancy to increase an overall level of confidence in the determined location information.
FIG. 8 illustrates a method 800 that facilitates determining a level of geographic redundancy in accordance with aspects of the subject disclosure. At 810, radio information can be received. Radio information can be for a set of radios (RS) including a first radio (RA) a second radio (RB) and a third radio (RC) of a wireless network. At 820, RGI can be determined from the radio information received at 810. RGI can be related to radios of a wireless network, e.g., RS. RGI can include the geographic information of radios in the wireless network.
At 830, it can be determined if the difference between the distance from the first to the third radio and the distance from the second to the third radio is within a predetermined range of values, e.g., the difference between distance AC can be less than a predetermined percentage of the distance BC. If the determination at 830 is affirmative, at 840, it can be determined if a distance between the first and second radio, e.g., distance AB, is less than a weighted average of the distance from the first to the third radio and the distance from the second to the third radio, e.g.,




  AB

        )

    .
  




Where 840 is determined in the affirmative, a level of geographic redundancy is indicated and method 800 proceeds to 850.

At 850, radio information can be updated based on the determined level of geographic redundancy. At this point, method 800 can end. A determined level of geographic redundancy can be employed to update radio information. This can facilitate selection of radios that meet predetermined ranking criteria associated with a predetermined level of geographic redundancy.
It will be noted that the exemplary threshold values and exemplary equations are merely for illustration and are non-limiting. It will further be noted that other equations and threshold values can be employed without departing from the scope of the present subject matter.
FIG. 9 presents an example embodiment 900 of a mobile network platform 910 that can implement and exploit one or more aspects of the disclosed subject matter described herein. Generally, wireless network platform 910 can include components, e.g., nodes, gateways, interfaces, servers, or disparate platforms, that facilitate both packet-switched (PS) (e.g., internet protocol (IP), frame relay, asynchronous transfer mode (ATM)) and circuit-switched (CS) traffic (e.g., voice and data), as well as control generation for networked wireless telecommunication. As a non-limiting example, wireless network platform 910 can be included in telecommunications carrier networks, and can be considered carrier-side components as discussed elsewhere herein. Mobile network platform 910 includes CS gateway node(s) 912 which can interface CS traffic received from legacy networks like telephony network(s) 940 (e.g., public switched telephone network (PSTN), or public land mobile network (PLMN)) or a signaling system #7 (SS7) network 970. Circuit switched gateway node(s) 912 can authorize and authenticate traffic (e.g., voice) arising from such networks. Additionally, CS gateway node(s) 912 can access mobility, or roaming, data generated through SS7 network 970; for instance, mobility data stored in a visited location register (VLR), which can reside in memory 930. Moreover, CS gateway node(s) 912 interfaces CS-based traffic and signaling and PS gateway node(s) 918. As an example, in a 3GPP UMTS network, CS gateway node(s) 912 can be realized at least in part in gateway GPRS support node(s) (GGSN). It should be appreciated that functionality and specific operation of CS gateway node(s) 912, PS gateway node(s) 918, and serving node(s) 916, is provided and dictated by radio technology(ies) utilized by mobile network platform 910 for telecommunication.
In addition to receiving and processing CS-switched traffic and signaling, PS gateway node(s) 918 can authorize and authenticate PS-based data sessions with served mobile devices. Data sessions can include traffic, or content(s), exchanged with networks external to the wireless network platform 910, like wide area network(s) (WANs) 950, enterprise network(s) 970, and service network(s) 980, which can be embodied in local area network(s) (LANs), can also be interfaced with mobile network platform 910 through PS gateway node(s) 918. It is to be noted that WANs 950 and enterprise network(s) 960 can embody, at least in part, a service network(s) like IP multimedia subsystem (IMS). Based on radio technology layer(s) available in technology resource(s) 917, packet-switched gateway node(s) 918 can generate packet data protocol contexts when a data session is established; other data structures that facilitate routing of packetized data also can be generated. To that end, in an aspect, PS gateway node(s) 918 can include a tunnel interface (e.g., tunnel termination gateway (TTG) in 3GPP UMTS network(s) (not shown)) which can facilitate packetized communication with disparate wireless network(s), such as Wi-Fi networks.
In embodiment 900, wireless network platform 910 also includes serving node(s) 916 that, based upon available radio technology layer(s) within technology resource(s) 917, convey the various packetized flows of data streams received through PS gateway node(s) 918. It is to be noted that for technology resource(s) 917 that rely primarily on CS communication, server node(s) can deliver traffic without reliance on PS gateway node(s) 918; for example, server node(s) can embody at least in part a mobile switching center. As an example, in a 3GPP UMTS network, serving node(s) 916 can be embodied in serving GPRS support node(s) (SGSN).
For radio technologies that exploit packetized communication, server(s) 914 in wireless network platform 910 can execute numerous applications that can generate multiple disparate packetized data streams or flows, and manage (e.g., schedule, queue, format . . . ) such flows. Such application(s) can include add-on features to standard services (for example, provisioning, billing, customer support . . . ) provided by wireless network platform 910. Data streams (e.g., content(s) that are part of a voice call or data session) can be conveyed to PS gateway node(s) 918 for authorization/authentication and initiation of a data session, and to serving node(s) 916 for communication thereafter. In addition to application server, server(s) 914 can include utility server(s), a utility server can include a provisioning server, an operations and maintenance server, a security server that can implement at least in part a certificate authority and firewalls as well as other security mechanisms, and the like. In an aspect, security server(s) secure communication served through wireless network platform 910 to ensure network's operation and data integrity in addition to authorization and authentication procedures that CS gateway node(s) 912 and PS gateway node(s) 918 can enact. Moreover, provisioning server(s) can provision services from external network(s) like networks operated by a disparate service provider; for instance, WAN 950 or Global Positioning System (GPS) network(s) (not shown). Provisioning server(s) can also provision coverage through networks associated to wireless network platform 910 (e.g., deployed and operated by the same service provider), such as femto-cell network(s) (not shown) that enhance wireless service coverage within indoor confined spaces and offload RAN resources in order to enhance subscriber service experience within a home or business environment by way of UE 975.
It is to be noted that server(s) 914 can include one or more processors configured to confer at least in part the functionality of macro network platform 910. To that end, the one or more processor can execute code instructions stored in memory 930, for example. It is should be appreciated that server(s) 914 can include a content manager 915, which operates in substantially the same manner as described hereinbefore.
In example embodiment 900, memory 930 can store information related to operation of wireless network platform 910. Other operational information can include provisioning information of mobile devices served through wireless platform network 910, subscriber databases; application intelligence, pricing schemes, e.g., promotional rates, flat-rate programs, couponing campaigns; technical specification(s) consistent with telecommunication protocols for operation of disparate radio, or wireless, technology layers; and so forth. Memory 930 can also store information from at least one of telephony network(s) 940, WAN 950, enterprise network(s) 960, or SS7 network 970. In an aspect, memory 930 can be, for example, accessed as part of a data store component or as a remotely connected memory store.

In addition, these components can execute from various computer readable media having various data structures stored thereon. The components may communicate via local and/or remote processes such as in accordance with a signal having one or more data packets (e.g., data from one component interacting with another component in a local system, distributed system, and/or across a network such as the Internet with other systems via the signal). As another example, a component can be an apparatus with specific functionality provided by mechanical parts operated by electric or electronic circuitry, which is operated by a software or firmware application executed by a processor, wherein the processor can be internal or external to the apparatus and executes at least a part of the software or firmware application. As yet another example, a component can be an apparatus that provides specific functionality through electronic components without mechanical parts, the electronic components can include a processor therein to execute software or firmware that confers at least in part the functionality of the electronic components. While various components have been illustrated as separate components, it will be appreciated that multiple components can be implemented as a single component, or a single component can be implemented as multiple components, without departing from example embodiments.
In addition, the term “or” is intended to mean an inclusive “or” rather than an exclusive “or.” That is, unless specified otherwise, or clear from context, “X employs A or B” is intended to mean any of the natural inclusive permutations. That is, if X employs A; X employs B; or X employs both A and B, then “X employs A or B” is satisfied under any of the foregoing instances. Moreover, articles “a” and “an” as used in the subject specification and annexed drawings should generally be construed to mean “one or more” unless specified otherwise or clear from context to be directed to a singular form.
Moreover, terms like “user equipment (UE),” “mobile station,” “mobile,” subscriber station,” “subscriber equipment,” “access terminal,” “terminal,” “handset,” and similar terminology, refer to a wireless device utilized by a subscriber or user of a wireless communication service to receive or convey data, control, voice, video, sound, gaming, or substantially any data-stream or signaling-stream. The foregoing terms are utilized interchangeably in the subject specification and related drawings. Likewise, the terms “radio,” “access point (AP),” “base station,” “Node B,” “evolved Node B (eNode B),” “home Node B (HNB),” “home access point (HAP),” and the like, are utilized interchangeably in the subject application, and refer to a wireless network component or appliance that serves and receives data, control, voice, video, sound, gaming, or substantially any data-stream or signaling-stream to and from a set of subscriber stations or provider enabled devices. Data and signaling streams can include packetized or frame-based flows.
Additionally, the terms “core-network,” “core,” “core carrier network,” “carrier-side,” “carrier network,” or similar terms can refer to components of a telecommunications network that typically provides some or all of aggregation, authentication, call control and switching, charging, service invocation, or gateways. Aggregation can refer to the highest level of aggregation in a service provider network wherein the next level in the hierarchy under the core nodes is the distribution networks and then the edge networks. UEs do not normally connect directly to the core networks of a large service provider but can be routed to the core by way of a switch or radio area network. Authentication can refer to determinations regarding whether the user requesting a service from the telecom network is authorized to do so within this network or not. Call control and switching can refer determinations related to the future course of a call stream across carrier equipment based on the call signal processing. Charging can be related to the collation and processing of charging data generated by various network nodes. Two common types of charging mechanisms found in present day networks can be prepaid charging and postpaid charging. Service invocation can occur based on some explicit action (e.g. call transfer) or implicitly (e.g., call waiting). It is to be noted that service “execution” may or may not be a core network functionality as third party network/nodes may take part in actual service execution. A gateway can be present in the core network to access other networks. Gateway functionality can be dependent on the type of the interface with another network.
Furthermore, the terms “user,” “subscriber,” “customer,” “consumer,” “prosumer,” “agent,” and the like are employed interchangeably throughout the subject specification, unless context warrants particular distinction(s) among the terms. It should be appreciated that such terms can refer to human entities or automated components (e.g., supported through artificial intelligence, as through a capacity to make inferences based on complex mathematical formalisms), that can provide simulated vision, sound recognition and so forth.
Aspects, features, or advantages of the subject matter can be exploited in substantially any, or any, wired, broadcast, wireless telecommunication, radio technology or network, or combinations thereof. Non-limiting examples of such technologies or networks include Geocast technology; broadcast technologies (e.g., sub-Hz, ELF, VLF, LF, MF, HF, VHF, UHF, SHF, THz broadcasts, etc.); Ethernet; X.25; powerline-type networking (e.g., PowerLine AV Ethernet, etc.); femto-cell technology; Wi-Fi; Worldwide Interoperability for Microwave Access (WiMAX); Enhanced General Packet Radio Service (Enhanced GPRS); Third Generation Partnership Project (3GPP or 3G) Long Term Evolution (LTE); 3GPP Universal Mobile Telecommunications System (UMTS) or 3GPP UMTS; Third Generation Partnership Project 2 (3GPP2) Ultra Mobile Broadband (UMB); High Speed Packet Access (HSPA); High Speed Downlink Packet Access (HSDPA); High Speed Uplink Packet Access (HSUPA); GSM Enhanced Data Rates for GSM Evolution (EDGE) Radio Access Network (RAN) or GERAN; UMTS Terrestrial Radio Access Network (UTRAN); or LTE Advanced.
What has been described above includes examples of systems and methods illustrative of the disclosed subject matter. It is, of course, not possible to describe every combination of components or methods herein. One of ordinary skill in the art may recognize that many further combinations and permutations of the claimed subject matter are possible. Furthermore, to the extent that the terms “includes,” “has,” “possesses,” and the like are used in the detailed description, claims, appendices and drawings such terms are intended to be inclusive in a manner similar to the term “comprising” as “comprising” is interpreted when employed as a transitional word in a claim.
