     TECHNICAL FIELD 
     The present application relates generally to wireless communications networks, and more particularly, to motion adaptive user equipment (UE) in a wireless communications network environment adapted for selecting one or more subsets of accessible user interface (UI) functions based, at least in part, on the determined motion of a UE. 
     BACKGROUND 
     In wireless communications networks, modern wireless communication devices, e.g., user equipment (UE), provide users more access to interesting and useful applications and functions than ever before. While this can be a huge benefit to a user, it can also contribute to distracting a user from important tasks at hand. For example, where a user, as a driver, is employing a cell phone or other mobile device in a vehicle, certain interactions with the user equipment can contribute to the distraction of the user that can endanger the user or other drivers. However, in contrast, where the user, as a passenger, is employing a cell phone or other mobile device and a vehicle, the same interactions with the user equipment may contribute to a dangerous condition for the user or other drivers. 
     Traditional systems for determining if user equipment is in motion commonly rely on the detection of motion in systems other than the user equipment. For example, speed sensors in the wheels of vehicles may be employed to determine the motion of a vehicle, and hence the motion of a user equipment inside the vehicle. However, this requires each user equipment to interface with each vehicle speed sensing system in a relatively seamless manner. This can be burdensome where there may be no set interface standard. Other traditional systems for determining if user equipment is in motion can be burdened by other technological difficulties. For example, an assisted global positioning system (AGPS) can be employed to determine the position of an AGPS detector, which can be co-located with a user equipment, to determine the position of user equipment. However, determining the position of the GPS detector can be power intensive, decreasing battery life for the mobile device. Further, AGPS capability is widely acknowledged to have substantial limitations resulting from geography, topology, or other forms of timing signal interference, such as building reflection, etc. These traditional systems, thus, often do not provide adequate information as to the relative movement of user equipment or can be overly taxing on the resources of the user equipment. As such, traditional systems often do not provide satisfactory results for motion detection. 
     Despite these limitations in effective and efficient motion detection for conventional motion detection systems, wireless carriers have attempted to limit or disable user equipment functionality based on UE motion. The results have been generally unsatisfactory as is evidenced by a lack of widely available wireless products that limit or defeat user access to the mobile device while the user device is in motion. Improvements to motion detection of UEs can lead to desirable improvements in limiting the use of mobile equipment in compliance with safety standards, ordinances, or conditions. 
     The above-described deficiencies of traditional motion sensing systems for wireless communications technologies are merely intended to provide an overview of some of the problems of conventional systems, and are not intended to be exhaustive. Other problems with conventional systems and corresponding benefits of the various non-limiting embodiments described herein may become further apparent upon review of the following description.

     DETAILED DESCRIPTION 
     The disclosed subject matter 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 disclosed subject matter. It may be evident, however, that the disclosed subject matter 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 disclosed subject matter. 
       FIG. 1  is a block diagram illustrating a system  100  that can determine motion-based user interface feature subsets in accordance with aspects of the disclosed subject matter. System  100  can include motion analysis (MA) component  110 . MA component  110  can access user equipment motion data (UEMD). UEMD can be data related to the motion of user equipment (UE). 
     In an aspect, UEMD data can include UE location data as disclosed in related application U.S. Ser. No. 12/712,424, incorporated herein by reference in its entirety. Similarly, UEMD data can include location data as disclosed in related application U.S. Ser. No. 12/836,471, incorporated herein by reference in its entirety. As such, UEMD data can include timed fingerprint locating (TFL) or TFL for idle-state UEs as disclosed in the related applications. The accuracy of TFL and TFL for idle-state UEs provides an improved ability to measure movement over more conventional methods. For example, TFL and TFL for idle-state UEs can provide more accurate speed measurements (change in location over time) than AGPS over a wider range of geographic/topographic conditions (as disclosed in the referenced applications). As a second example, TFL and TFL for idle-state UEs can provide for easier implementation and higher confidence as compared to more conventional systems such as speed sensors in a vehicle where the location measurement is for the UE itself rather than being associated with a vehicle, especially where the UE can move through a variety of vehicles that can present significant handshake issues, correlation issues, etc. 
     Generally, for TFL data and TFL for idle-state data, a given propagation delay, B, can be determined for location aware UEs within a TFL wireless environment. Further, cell site delay, A, can be initially determined where an observed UE time difference, C, is also available by subtracting the propagation delay, B, from the observed UE time difference, C, (e.g., A=C−B). Cell site delay, A, is generally stable over periods of hours to days. Assuming A is relatively stable, B can be determined for C values (e.g., B=C−A). Wherein UEs (e.g., both location enabled and non-location enabled UEs) can make time data (e.g., an observed UE time difference, C) available, for example by transmitting it wirelessly, the propagation delay for most or all UEs can be determined with a simple calculation, given a determined A value. Further, given that the propagation delay, B, is essentially proportional to distance (e.g., B*speed of light=distance), the propagation delay, B, can be employed to determine a region of probable locations for a UE at a set distance from the related NodeB for which the propagation delay was measured. This can provide a centroid region in which the UE is likely to be located. T FL data and TFL for idle-state data can thus provide for computation of UE position and, as such, UE motion wherein UE motion can be a change in UE position over time. 
     MA component  110  can analyze UEMD to determine compliance with one or more motion rules. These motion rules can be related to the use of the UE while the UE is in motion. In an aspect, MA component  110  can determine one or more subsets of user interface (UI) functions that can be accessed for a given UE motion condition. As a non-limiting example, a rule can be that the keypad on a UE can accept only “9-1-1” key sequences while the UE is traveling at more than 15 miles per hour (MPH). As a second non-limiting example, a rule can be that the “ON” button of a UE cannot be activated for 60 seconds after a UE drops below 5 MPH after having descended from more than 2000 feet of vertical elevation in a pattern associated with the glide path of a common carrier aircraft. It will be appreciated by one of skill in the art that the terms rule, directive, goal, preference, argument, policy, etc. can be interchangeably used without departing from the scope of the presently disclosed subject matter and that all such permutations are within the present scope of the subject matter wherein the term “rule” is employed simply to provide concise and clear disclosure without any intention of being strictly limiting. 
     In an aspect, MA component  110  can analyze UEMD to determine UE motion. UE motion can include the position, speed, acceleration, velocity, direction, magnitude, etc. of a UE. As such, UEMD can be used to map the motion of a UE in two dimensions, e.g., motion on or near the surface of the earth, or three dimensions, e.g., motion above (or below) the surface of the earth, for example, by plane, gondola, helicopter, etc. UE motion analysis can facilitate limiting the functionality of the UI based, at least in part, on the motion. In an aspect, motion can include instantaneous motion and historical motion. Further, motion can include predictive motion, or anticipated motion, such as anticipating motion based on inference, etc. Moreover, motion can be classified, wherein a motion class can be employed to represent motions that fall into broader classes, as non-limiting examples: a vehicular motion class comprising car, bus, motorcycle, tram, trolley, or other similar motions; a high speed motion class comprising plane, high speed train, etc., a pedestrian class comprising walking, bicycling, escalator, elevator, etc. 
     UE motion can be applied to the motion rules by MA component  110  to form a determination of subsets of UI features that can be made accessible through the UE. Subset information can be accessed by UI component  120 . As such, UI functionality can be adapted to the motion of a UE. As a non-limiting example, a parcel delivery corporation can have a policy that company issued UEs can only display map information above 5 MPH but have full functionality below that speed. In this example, a rule can be to limit the UI to displaying and interactive map above 5 MPH. As a second example, a county can have an ordinance that allows only emergency or hands-free interaction with a UE when the UE is in a moving vehicle. In this example, a rule can be that when within the county and where vehicle class motion is determined, the UE can operate in hands-free mode and allow non-hands-free emergency calls (e.g., 911, or similar) until a pedestrian motion class is determined, the UE has been stationary for 60 seconds, or the UE is no longer in the county. One of skill in the art will appreciate that rules can be of any level of sophistication without departing from the scope of the presently disclosed subject matter. Further, it will be appreciated that rules can be employed as individual elements to form more complex decision making processes within the scope of the present disclosure. 
     In an aspect, user interfaces can include access to applications, such as by way of an icon on a smartphone, a dedicated key on device keypad, etc. MA component  110  can determine interaction with these applications at the UI level. MA component  110  can access one or more indicators related to interaction with applications. For example, a flag can be set that an application can or cannot be accessed based on the motion of the UE. As such, it is envisioned that applications can include one or more components that interact with the presently disclosed subject matter, for example by accessing the one or more indicators, as part of being compliant with said disclosed subject matter. Thus, as a non-limiting example, a voice recorder application, “VoiceApp”, can include support to check for a motion permission to operate. As such, when a UE is in motion, MA component  110  can specify that “VoiceApp” is not allowed to operate. Therefore, when the UE is in motion and a user attempts to active the “VoiceApp” application, the application can refuse to open based on the designation of MA component  110 . It is further envisioned that motion permissions can include partial operation, no operation, full operation, operation dependant on other metrics, etc., without departing from the scope of the subject disclosure. One of skill in the art will appreciate that the term “application” is employed in this paragraph as a general term to represent programs, software applications, etc., that can reside and/or execute, in whole or in part, on a UE. 
       FIG. 2  is a block diagram of a system  200  that can employ motion-based user interface feature subsets in accordance with aspects of the disclosed subject matter. System  200  can include MA component  210 . MA component  210  can be the same as, or similar to, MA component  110 . MA component  210  can access UEMD. MA component  210  can analyze UEMD to determine the motion of a UE. MA component  210  can further determine one or more subsets of UI features that can be made accessible by way of the UE based, at least in part, on the motion of the UE. 
     System  200  can further include UI component  220 . UI component  220  can access subset information determined by MA component  210 . UI component  220  can selectively make available features of a UI in accord with the one or more subsets of UI features as determined by MA component  210 . 
     In an aspect, UI component  220  can comprise override component  230 . Override component  230  can allow an override of the limited or disabled UI functions. That is, an override condition can result in allowing UI functionality that would otherwise be disabled or limited due to UE motion. As a non-limiting example, an override can allow a passenger to operate a moving UE without limitation, e.g., a passenger in a vehicle can operate a UE in a different UI functional capacity than a driver of a vehicle where the passenger can provide the override and the driver cannot. The particular override is beyond the scope of the present disclosure, however one of skill in the art will appreciate that the presently described subject matter is capable of accessing overrides to provide override functionality. In an aspect, override component  230  can provide for an override hook in a software development environment to allow inclusion of override functionality in UE software. 
     As a non-limiting example, system  200  can be configured to limit a UI to allow only outgoing emergency calls when moving at more than 20 MPH to prevent a user from operating the UE while driving. Where the exemplary UE is moving at 30 MPH the UI can be limited to outgoing emergency calls only. However, where the exemplary UE is used by a passenger in a vehicle, the prohibition on full UE use can be overridden by providing an override by way of exemplary override component  230 . Where, for example, the override is provided by occasionally completing a task that requires high levels of concentration that would be overly burdensome for most vehicle operators, a passenger can have unfettered use of the UE. As such, facilitating an override provides a degree of selectivity that can be important in distinguishing between users that should be burdened and those that should not be burdened by rules relating to the motion of a UE. 
       FIG. 3  is a block diagram of a system  300  that can determine motion-based user interface feature subsets in accordance with aspects of the disclosed subject matter. System  300  can be the same as, or similar to, system  100  or  200 . System  300  can include MA component  310  and UI component  320 , which can be the same as, or similar to, the corresponding components of system  100  or  200 . System  300  can further include local position component  340 . Local position component  340  can facilitate auxiliary determination of position. The auxiliary determination of UE position can be beneficial in determining the one or more subsets of UI functions to make accessible by way of a UE. This local position data can be auxiliary or supplementary location information to UEMD, including TFL data and TFL for idle-state data. As a non-limiting example, a local position component can access a UE camera to determine that the UE is likely located in the passenger portion of a vehicle rather than in the operator portion of the vehicle. As a second non-limiting example, a local position component can access RFID tags in a vehicle to determine position within a vehicle. One of skill in the art will appreciate that various systems and techniques can be employed in an auxiliary determination of UE position and that all such systems and techniques are within the scope of the subject disclosure. 
     The auxiliary determination of position can be employed in conjunction with motion determinations when further determining one or more subsets of UI functions to make available. As a non-limiting example, where a UE camera is employed by local position component  340  to determine that the UE is most likely in the passenger area of a vehicle, a different subset of UI functions can be made available by MA component  310  than if local position component  340  determined the UE was most likely in the operator position of a vehicle. As such, despite a UE moving as a speed that would otherwise limit the UI functionality, the position of the UE within the frame of movement can provide information that can be employed to allow a different level of UI functionality. As a further non-limiting example, a vehicle operator positioned UE in motion can be limited to emergency calls only, while a passenger positioned UE in motion can be limited to emergency calls and incoming calls only, while a UE not in motion can be allowed full UI functionality. 
       FIG. 4  is a block diagram of a system  400  that can update motion-based user interface feature subset determination rules in accordance with aspects of the disclosed subject matter. System  400  can be the same as, or similar to, system  100 ,  200 , or  300 . System  400  can include MA component  410  and UI component  420 , which can be the same as, or similar to, the corresponding components of system  100 ,  200  or  300 . System  400  can further include enterprise rule engine component  450 . Enterprise rule engine component  450  can facilitate access to one or more motion rules. In an aspect, enterprise rule engine component  450  can generate one or more motion rules. These motion rules can be related to goals of the enterprise. As a non-limiting example, a goal of an enterprise can be to comply with ordinances related to UE usage in vehicles or standards related to worker safety. As such, the exemplary enterprise rule engine component  450  can generate one or more motion rules reflective of the goals of the enterprise, for example, a rule can designate that a UI is disabled above 25 MPH in a first county and disabled above 5 MPH in a second county in compliance with the ordinances of the first and second counties. 
     System  400  can further include rule library component  455 . Rule library component  455  can be a rule store. As a non-limiting example, rule library component  455  can be a local rule database. In an aspect, rule library component  455  can store one or more motion rules. In a further aspect, rule library component  455  can update the one or more rules stored therein. Motion rules can be accessed by rule library component  455  by way of enterprise rule engine component  450 . As such enterprise rule engine component  450  can facilitate generating and updating motion rules associated with rule library component  455 . 
     Motion rules associated with rule library component  455  can be employed in determinations made by MA component  410 . As such, where motion rules change relative to UE scope, the motion rules can be updated to remain relevant. As a non-limiting example, rule library component  455  can facilitate access to California motion rules for a corporate issued UE. Where the corporate issued UE travels with an employee-user to Virginia, rule library component  455  can access Virginia motion rules. Access to the exemplary Virginia motion rules can be facilitated by enterprise rule engine component  450 . For example, enterprise rule engine component  450  can generate a Virginia-centric set of motion rules that are also compliant with motion rules of the corporate owner of the UE. One of skill in the art will appreciate that updating motion rules can provide additional desirable functionality to systems like system  400  and that all such systems or techniques for storing, updating, and generating motion rules are within the scope of the present disclosure. 
       FIG. 5  is a block diagram of a system  500  that can determine motion-based user interface feature subsets in accordance with aspects of the disclosed subject matter. System  500  can be the same as, or similar to, system  100 ,  200 ,  300 , or  400 . System  500  can include MA component  510  and UI component  520  which can be the same as, or similar to, the corresponding components of system  100 ,  200 ,  300  or  400 . System  500  can further comprise user preference component  560 . User preference component  560  can facilitate access to one or more user preferences related to motion rules. In an aspect, user preferences can comprise voluntary and involuntary user preferences. Voluntary user preferences can be those preferences indicated by a user. Involuntary user preferences can be those preferences indicated for a user. As a non-limiting example, a voluntary user preference can be indicated by “child 1” for “child 1” while an involuntary user preference can be indicated by “parent 1” for “child 1”. As a second non-limiting example, a voluntary user preference can be indicated by “employee 1” for “employee 1” while an involuntary user preference can be indicated by “supervisor 1” for “employee 1”. Thus for example, “child 1” can indicate that access to entertainment applications is limited while driving and “parent 1” can indicate that access to social media applications is limited while “child 1” is driving. 
     In an aspect, user preference component  560  can facilitate tiered motion rules for various users. Each user can comprise a particular combination of motion rules in light of one or more levels of voluntary and/or involuntary user preferences. As a non-limiting example, a user preference component can facilitate access to a user profile including motion rules from “employee 1”, the employee&#39;s direct supervisor, and the employee&#39;s regional director. Other permutations of user preference tiers are readily envisioned and one of skill in the art will appreciate that all such permutations are within the scope of the subject 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  through  FIG. 11 . 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. For example, one or more example methods disclosed herein could alternatively be represented as a series of interrelated states or events, such as in a state diagram. Moreover, interaction diagram(s) may represent methods in accordance with the disclosed subject matter when disparate entities enact disparate portions of the methodologies. 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 features or advantages 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 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  is exemplary flowchart of procedures defining a method  600  for determining at least a subset of accessible user interface functions in accordance with aspects of the disclosed subject matter. At  610  of method  600 , user equipment motion data (UEMD) can be accessed. UEMD can include timed fingerprint locating (TFL) or TFL for idle-state UEs as disclosed in the related applications. UEMD can relate to the position, speed, acceleration, velocity, direction, magnitude, etc. of a UE. As such, at  620 , the motion of a UE can be determined based, at least in part, on the UEMD. For example, where the location of a UE is given at two points in time by TFL data or TFL for idle-state data, the change in location over the change in time can be related to the motion, e.g., the speed, of the UE. 
     At  630 , one or more subsets of user interface functions can be determined based, at least in part, on the UE motion determination from  620 . It should be noted that a subset can include all, some, or none of a superset, and as such, a subset of user interface functions can include all UI functions, some UI functions, or no UI functions. At this point method  600  can end. 
     As a non-limiting example, a first UI function subset can include all UI functions, a second UI function subset can include all telephone keypad functions, a third UI function subset can include only UI functions for dialing “9-1-1” (or other emergency numbers), etc. Thus, based on the motion of a UE, different functionality can be made available to a user through the UI by determining which subset(s) of UI functions are accessible. As a non-limiting example, when a UE is moving at more than 20 MPH, only UI functions for dialing “9-1-1” can be allowed. One of skill in the art will appreciate that numerous other examples of accessible UI functions are possible and that all such examples are within the scope of the present disclosure. 
       FIG. 7  is an exemplary flowchart of procedures defining a method  700  for selectively limiting the functionality of a UE based, at least in part, on a subset of accessible user interface functions in accordance with aspects of the disclosed subject matter. At  710 , UEMD can be accessed. At  720 , UE motion can be determined based on UEMD from  710 . At  730  one or more subsets of accessible UI functions can be determined based, at least in part, on the UE motion from  720 . At  740 , the UI of a UE can be selectively limited based, at least in part, on the one or more subsets of accessible UI functions determined at  730 . At this point method  700  can end. 
       FIG. 8  is an exemplary flowchart of procedures defining a method  800  for selectively limiting the functionality of a UE based, at least in part, on a subset of accessible user interface functions in accordance with aspects of the disclosed subject matter. At  810 , UEMD can be accessed. At  820 , UE motion can be determined based on UEMD from  810 . At  830 , one or more subsets of accessible UI functions can be determined based, at least in part, on the UE motion from  820 . 
     At  840 , override data can be accessed. Override data can be one or more indicators of an override condition as disclosed supra. For example, an override condition can exist where a motion rule as applied would result in UI limitations inconsistent with the intent of the motion rule, such as, limiting vehicle passenger use of a UE when the intent of the motion rule is to limit vehicle operator use of the UE. At  850 , the UI of a UE can be selectively limited based, at least in part, on the one or more subsets of accessible UI functions determined at  830 , the override data accessed at  840 , or both. As a non-limiting example, an override condition can result in no limitation being placed on the UI of a UE even where the UE experiences motion that would otherwise result in limited UI functionality. At this point method  800  can end. 
       FIG. 9  is an exemplary flowchart of procedures defining a method  900  for determining at least a subset of accessible user interface functions in accordance with aspects of the disclosed subject matter. At  910 , UEMD can be accessed. At  920 , UE motion can be determined based on UEMD from  910 . At  930 , local position data can be accessed. As disclosed hereinabove, local position data can be auxiliary UE position data that can serve to improve selective application of motion rules to a UE. For example, local position data can be accessed by way of position beacons in a user environment, wherein UE proximity to said position beacon can be employed in determining how to apply motion rules. At  940 , one or more subsets of accessible UI functions can be determined based, at least in part, on the UE motion from  920 , local position data from  930 , or both. At this point method  900  can end. 
       FIG. 10  is an exemplary flowchart of procedures defining a method  1000  for determining at least a subset of accessible user interface functions in accordance with aspects of the disclosed subject matter. At  1010 , UEMD can be accessed. At  1020 , UE motion can be determined based on UEMD from  1010 . At  1030 , user preference data can be accessed. At  1040 , one or more subsets of accessible UI functions can be determined based, at least in part, on the UE motion from  1020 , user preference data from  1030 , or both. At this point method  1000  can end. 
     As presently disclosed hereinabove, user preference data can be voluntary or involuntary. Further, as disclosed herein, user preference data can be employed in a tiered or hierarchical form. As such, user preference data can impact what UI functions are made available to a UE. As a non-limiting example, a user preference can indicate that a loud ring tone be employed when a UE is in motion above an indicated speed. As a second non-limiting example, a user preference can indicate that text messages should be queued but not presented by way of the UI until the UE is moving at less than 5 MPH. One of skill in the art will appreciate that nearly unlimited number of combinations of user preference data can be employed and that all such permutations are within the scope of the present disclosure. 
       FIG. 11  is an exemplary flowchart of procedures defining a method  1100  for determining at least a subset of accessible user interface functions in accordance with aspects of the disclosed subject matter. At  1110 , UEMD can be accessed. At  1120 , UE motion can be determined based on UEMD from  1110 . At  1130 , rule update data can be accessed. As disclosed herein, motion rules can be updated dynamically. As such, method  1100  facilitates accessing updated rules. As a non-limiting example, a corporation may update rules for employee UEs. These corporate updates can be accessed at  1130 . One of skill in the art will appreciate that many other permutations of access to rule update data remains within the scope of the subject disclosure. At  1140 , one or more UI functionality access rules can be updated based, at least in part, on the rule update data accessed at  1130 . At  1150 , one or more subsets of accessible UI functions can be determined based, at least in part, on the UE motion from  1120 . At this point method  1100  can end.

     The system bus  1208  can be any of several types of bus structure that may further interconnect to a memory bus (with or without a memory controller), a peripheral bus, and a local bus using any of a variety of commercially available bus architectures. The system memory  1206  includes read-only memory (ROM)  1210  and random access memory (RAM)  1212 . A basic input/output system (BIOS) is stored in a non-volatile memory  1210  such as ROM, EPROM, EEPROM, which BIOS contains the basic routines that help to transfer information between elements within the computer  1202 , such as during start-up.

The hard disk drive  1214  (or  1215 ), magnetic disk drive  1216  and optical disk drive  1220  can be connected to the system bus  1208  by a hard disk drive interface  1224 , a magnetic disk drive interface  1226  and an optical drive interface  1228 , respectively. The interface  1224  for external drive implementations includes at least one or both of Universal Serial Bus (USB) and IEEE1394 interface technologies. Other external drive connection technologies are within contemplation of the subject matter disclosed herein. 
     The drives and their associated computer-readable media provide nonvolatile storage of data, data structures, computer-executable instructions, and so forth. For the computer  1202 , the drives and media accommodate the storage of any data in a suitable digital format. Although the description of computer-readable media above refers to a HDD, a removable magnetic diskette, and a removable optical media such as a CD or DVD, it should be appreciated by those skilled in the art that other types of media which are readable by a computer, such as zip drives, magnetic cassettes, flash memory cards, cartridges, and the like, may also be used in the exemplary operating environment, and further, that any such media may contain computer-executable instructions for performing the methods of the disclosed subject matter. 
     A number of program modules can be stored in the drives and RAM  1212 , including an operating system  1230 , one or more application programs  1232 , other program modules  1234  and program data  1236 . All or portions of the operating system, applications, modules, and/or data can also be cached in the RAM  1212 . It is appreciated that the disclosed subject matter can be implemented with various commercially available operating systems or combinations of operating systems. 
     A user can enter commands and information into the computer  1202  through one or more wired/wireless input devices, e.g., a keyboard  1238  and a pointing device, such as a mouse  1240 . Other input devices (not shown) may include a microphone, an IR remote control, a joystick, a game pad, a stylus pen, touch screen, or the like. These and other input devices are often connected to the processing unit  1204  through an input device interface  1242  that is coupled to the system bus  1208 , but can be connected by other interfaces, such as a parallel port, an IEEE1394 serial port, a game port, a USB port, an IR interface, etc.

The logical connections depicted include wired/wireless connectivity to a local area network (LAN)  1252  and/or larger networks, e.g., a wide area network (WAN)  1254 . Such LAN and WAN networking environments are commonplace in offices and companies, and facilitate enterprise-wide computer networks, such as intranets, all of which may connect to a global communications network, e.g., the Internet. 
     When used in a LAN networking environment, the computer  1202  is connected to the local network  1252  through a wired and/or wireless communication network interface or adapter  1256 . The adapter  1256  may facilitate wired or wireless communication to the LAN  1252 , which may also include a wireless access point disposed thereon for communicating with the wireless adapter  1256 .

       FIG. 13  presents an example embodiment  1300  of a mobile network platform  1310  that can implement and exploit one or more aspects of the disclosed subject matter described herein. Generally, wireless network platform  1310  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. Mobile network platform  1310  includes CS gateway node(s)  1312  which can interface CS traffic received from legacy networks like telephony network(s)  1340  (e.g., public switched telephone network (PSTN), or public land mobile network (PLMN)) or a signaling system #7 (SS7) network  1370 . Circuit switched gateway node(s)  1312  can authorize and authenticate traffic (e.g., voice) arising from such networks. Additionally, CS gateway node(s)  1312  can access mobility, or roaming, data generated through SS7 network  1370 ; for instance, mobility data stored in a visited location register (VLR), which can reside in memory  1330 . Moreover, CS gateway node(s)  1312  interfaces CS-based traffic and signaling and PS gateway node(s)  1318 . As an example, in a 3GPP UMTS network, CS gateway node(s)  1312  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)  1312 , PS gateway node(s)  1318 , and serving node(s)  1316 , is provided and dictated by radio technology(ies) utilized by mobile network platform  1310  for telecommunication. 
     In the disclosed subject matter, in addition to receiving and processing CS-switched traffic and signaling, PS gateway node(s)  1318  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  1310 , like wide area network(s) (WANs)  1350 , enterprise network(s)  1370 , and service network(s)  1380 , which can be embodied in local area network(s) (LANs), can also be interfaced with mobile network platform  1310  through PS gateway node(s)  1318 . It is to be noted that WANs  1350  and enterprise network(s)  1360  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)  1317 , packet-switched gateway node(s)  1318  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)  1318  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  1300 , wireless network platform  1310  also includes serving node(s)  1316  that, based upon available radio technology layer(s) within technology resource(s)  1317 , convey the various packetized flows of data streams received through PS gateway node(s)  1318 . It is to be noted that for technology resource(s)  1317  that rely primarily on CS communication, server node(s) can deliver traffic without reliance on PS gateway node(s)  1318 ; 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)  1316  can be embodied in serving GPRS support node(s) (SGSN). 
     For radio technologies that exploit packetized communication, server(s)  1314  in wireless network platform  1310  can execute numerous applications (e.g., location services, online gaming, wireless banking, wireless device management . . . ) 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  1310 . Data streams (e.g., content(s) that are part of a voice call or data session) can be conveyed to PS gateway node(s)  1318  for authorization/authentication and initiation of a data session, and to serving node(s)  1316  for communication thereafter. In addition to application server, server(s)  1314  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  1310  to ensure network&#39;s operation and data integrity in addition to authorization and authentication procedures that CS gateway node(s)  1312  and PS gateway node(s)  1318  can enact. Moreover, provisioning server(s) can provision services from external network(s) like networks operated by a disparate service provider; for instance, WAN  1350  or Global Positioning System (GPS) network(s) (not shown). Provisioning server(s) can also provision coverage through networks associated to wireless network platform  1310  (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. 
     It is to be noted that server(s)  1314  can include one or more processors configured to confer at least in part the functionality of macro network platform  1310 . To that end, the one or more processor can execute code instructions stored in memory  1330 , for example. It is should be appreciated that server(s)  1314  can include a content manager  1315 , which operates in substantially the same manner as described hereinbefore. 
     In example embodiment  1300 , memory  1330  can store information related to operation of wireless network platform  1310 . In particular, memory  1330  can include contents of memory  440  in example system  400 . Other operational information can include provisioning information of mobile devices served through wireless platform network  1310 , 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  1330  can also store information from at least one of telephony network(s)  1340 , WAN  1350 , enterprise network(s)  1360 , or SS7 network  1370 .

Coupled to receiver/transmitter  1416  is a multiplexer/demultiplexer  1417  that facilitates manipulation of signal in time and frequency space. Electronic component  1417  can multiplex information (data/traffic and control/signaling) according to various multiplexing schemes such as time division multiplexing (TDM), frequency division multiplexing (FDM), orthogonal frequency division multiplexing (OFDM), code division multiplexing (CDM), space division multiplexing (SDM). In addition, mux/demux component  1417  can scramble and spread information (e.g., codes) according to substantially any code known in the art; e.g., Hadamard-Walsh codes, Baker codes, Kasami codes, polyphase codes, and so on. A modulator/demodulator  1418  is also a part of communication platform  1415 , and can modulate information according to multiple modulation techniques, such as frequency modulation, amplitude modulation (e.g., M-ary quadrature amplitude modulation (QAM), with M a positive integer), phase-shift keying (PSK), and the like. Communication platform  1415  also includes a coder/decoder (codec) component  1419  that facilitates decoding received signal(s), and coding signal(s) to convey. 
     Access point  1405  also includes a processor  1435  configured to confer functionality, at least in part, to substantially any electronic component in AP  1405 . In particular, processor  1435  can facilitate determination of propagation delay information of RF signal, or microwave signal, among communication platform  1415  and antennas  1420   1 - 1420   N  in accordance with various aspects and embodiments disclosed herein. Power supply  1425  can attach to a power grid and include one or more transformers to achieve power level that can operate AP  1405  components and circuitry. Additionally, power supply  1425  can include a rechargeable power component to ensure operation when AP  1405  is disconnected from the power grid, or in instances, the power grid is not operating.

     In AP  1405 , memory  1445  can store data structures, code instructions and program modules, system or device information, code sequences for scrambling, spreading and pilot transmission, location intelligence storage, determined delay offset(s), over-the-air propagation models, and so on. Processor  1435  is coupled to the memory  1445  in order to store and retrieve information necessary to operate and/or confer functionality to communication platform  1415 , calibration platform  1412 , and other components (not shown) of access point  1405 . 
     As used in this application, the terms “component,” “system,” “platform,” “layer,” “selector,” “interface,” and the like are intended to refer to a computer-related entity or an entity related to an operational apparatus with one or more specific functionalities, wherein the entity can be either hardware, a combination of hardware and software, software, or software in execution. As an example, a component may be, but is not limited to being, a process running on a processor, a processor, an object, an executable, a thread of execution, a program, and/or a computer. By way of illustration, both an application running on a server and the server can be a component. One or more components may reside within a process and/or thread of execution and a component may be localized on one computer and/or distributed between two or more computers. Also, 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. 
     Moreover, the word “exemplary” is used herein to mean serving as an example, instance, or illustration. Any aspect or design described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other aspects or designs. Rather, use of the word exemplary is intended to present concepts in a concrete fashion. 
     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 device,” “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 “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 from a set of subscriber stations. Data and signaling streams can be packetized or frame-based flows. 
     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 supported through artificial intelligence, e.g., a capacity to make inference based on complex mathematical formalisms, which can provide simulated vision, sound recognition and so forth. 
     As used herein, the terms “infer” or “inference” generally refer to the process of reasoning about or inferring states of the system, environment, and/or user from a set of observations as captured via events and/or data. Inference can be employed to identify a specific context or action, or can generate a probability distribution over states, for example. The inference can be probabilistic—that is, the computation of a probability distribution over states of interest based on a consideration of data and events. Inference can also refer to techniques employed for composing higher-level events from a set of events and/or data. Such inference results in the construction of new events or actions from a set of observed events and/or stored event data, whether or not the events are correlated in close temporal proximity, and whether the events and data come from one or several event and data sources. 
     Wi-Fi, or Wireless Fidelity, allows connection to the Internet from a couch at home, a bed in a hotel room, or a conference room at work, without wires. Wi-Fi is a wireless technology similar to that used in a cell phone that enables such devices, e.g., computers, to send and receive data indoors and out; anywhere within the range of a base station. Wi-Fi networks use radio technologies called IEEE802.11(a, b, g, n, etc.) to provide secure, reliable, fast wireless connectivity. A Wi-Fi network can be used to connect computers to each other, to the Internet, and to wired networks (which use IEEE802.3 or Ethernet). Wi-Fi networks operate in the unlicensed 2.4 and 5 GHz radio bands, at an 11 Mbps (802.11b) or 54 Mbps (802.11a) data rate, for example, or with products that contain both bands (dual band), so the networks can provide real-world performance similar to the basic “10BaseT” wired Ethernet networks used in many offices. 
     Various aspects or features described herein can be implemented as a method, apparatus, or article of manufacture using standard programming and/or engineering techniques. In addition, various aspects disclosed in the subject specification can also be implemented through program modules stored in a memory and executed by a processor, or other combination of hardware and software, or hardware and firmware. 
     The term “article of manufacture” as used herein is intended to encompass a computer program accessible from any computer-readable device or media. Computing devices typically include a variety of media, which can include computer-readable storage media and/or communications media, which two terms are used herein differently from one another as follows. Computer-readable storage media can be any available storage media that can be accessed by the computer and includes both volatile and nonvolatile media, removable and non-removable media. By way of example, and not limitation, computer-readable storage media can be implemented in connection with any method or technology for storage of information such as computer-readable instructions, program modules, structured data, or unstructured data. Computer-readable storage media can include, but are not limited to, RAM, ROM, EEPROM, flash memory or other memory technology, CD-ROM, digital versatile disk (DVD) or other optical disk storage, magnetic cassettes, magnetic tape, magnetic disk storage or other magnetic storage devices, or other tangible and/or non-transitory media which can be used to store desired information. Computer-readable storage media can be accessed by one or more local or remote computing devices, e.g., via access requests, queries or other data retrieval protocols, for a variety of operations with respect to the information stored by the medium. 
     Communications media typically embody computer-readable instructions, data structures, program modules or other structured or unstructured data in a data signal such as a modulated data signal, e.g., a carrier wave or other transport mechanism, and includes any information delivery or transport media. The term “modulated data signal” or signals refers to a signal that has one or more of its characteristics set or changed in such a manner as to encode information in one or more signals. By way of example, and not limitation, communication media include wired media, such as a wired network or direct-wired connection, and wireless media such as acoustic, RF, infrared and other wireless media. 
     As it employed in the subject specification, the term “processor” can refer to substantially any computing processing unit or device comprising, but not limited to comprising, single-core processors; single-processors with software multithread execution capability; multi-core processors; multi-core processors with software multithread execution capability; multi-core processors with hardware multithread technology; parallel platforms; and parallel platforms with distributed shared memory. Additionally, a processor can refer to an integrated circuit, an application specific integrated circuit (ASIC), a digital signal processor (DSP), a field programmable gate array (FPGA), a programmable logic controller (PLC), a complex programmable logic device (CPLD), a discrete gate or transistor logic, discrete hardware components, or any combination thereof designed to perform the functions described herein. Processors can exploit nano-scale architectures such as, but not limited to, molecular and quantum-dot based transistors, switches and gates, in order to optimize space usage or enhance performance of user equipment. A processor also can be implemented as a combination of computing processing units. 
     In the subject specification, terms such as “store,” “data store,” “data storage,” “database,” “repository,” and substantially any other information storage component relevant to operation and functionality of a component, refer to “memory components,” or entities embodied in a “memory” or components comprising the memory. It will be appreciated that the memory components described herein can be either volatile memory or nonvolatile memory, or can include both volatile and nonvolatile memory. In addition, memory components or memory elements can be removable or stationary. Moreover, memory can be internal or external to a device or component, or removable or stationary. Memory can include various types of media that are readable by a computer, such as hard-disc drives, zip drives, magnetic cassettes, flash memory cards or other types of memory cards, cartridges, or the like. 
     By way of illustration, and not limitation, nonvolatile memory can include read only memory (ROM), programmable ROM (PROM), electrically programmable ROM (EPROM), electrically erasable ROM (EEPROM), or flash memory. Volatile memory can include random access memory (RAM), which acts as external cache memory. By way of illustration and not limitation, RAM is available in many forms such as synchronous RAM (SRAM), dynamic RAM (DRAM), synchronous DRAM (SDRAM), double data rate SDRAM (DDR SDRAM), enhanced SDRAM (ESDRAM), Synchlink DRAM (SLDRAM), and direct Rambus RAM (DRRAM). Additionally, the disclosed memory components of systems or methods herein are intended to comprise, without being limited to comprising, these and any other suitable types of memory. 
     What has been described above includes examples of the various embodiments. It is, of course, not possible to describe every conceivable combination of components or methodologies for purposes of describing the embodiments, but one of ordinary skill in the art may recognize that many further combinations and permutations are possible. Accordingly, the detailed description is intended to embrace all such alterations, modifications, and variations that fall within the spirit and scope of the appended claims. 
     In particular and in regard to the various functions performed by the above described components, devices, circuits, systems and the like, the terms (including a reference to a “means”) used to describe such components are intended to correspond, unless otherwise indicated, to any component which performs the specified function of the described component, e.g., a functional equivalent, even though not structurally equivalent to the disclosed structure, which performs the function in the herein illustrated exemplary aspects of the embodiments. In this regard, it will also be recognized that the embodiments includes a system as well as a computer-readable medium having computer-executable instructions for performing the acts and/or events of the various methods. 
     In addition, while a particular feature may have been disclosed with respect to only one of several implementations, such feature may be combined with one or more other features of the other implementations as may be desired and advantageous for any given or particular application. Furthermore, to the extent that the terms “includes,” and “including” and variants thereof are used in either the detailed description or the claims, these terms are intended to be inclusive in a manner similar to the term “comprising.”
