20240040471
The subject application is related to different approaches to handling wireless communication in networked computer systems and, for example, to limiting the use of certain bands by user equipment above ground level.
As network implementations have continued to increase in size and diversity, a variety of different bands are available for use by different wireless carriers. Problems can occur because some of these bands are thought by some to potentially interfere with the operation of certain aircraft systems. Addressing these assessments of potential interference can be challenging because of the variety of locations in which access points and user equipment can operate.
In some circumstances, for some bands, potential and actual interference has resulted an inability for wireless carriers to fully deploy spectrum.
The technology described herein is illustrated by way of example and not limited in the accompanying figures in which like reference numerals indicate similar elements and in which:
Generally speaking, one or more embodiments of a system described herein can facilitate, based on a determination that a user equipment is operating from an airborne aircraft, limiting the use signals with potentially interfering bands. It is important to note that, as used herein, signals operating at ‘potentially interfering bands’ are not considered herein to have been established to be actually interfering with other signals in the different example circumstances discussed herein. One or more embodiments can operate to reduce or eliminate the potential for interference by these signals using different approaches.
In addition, one or more embodiments described herein can be directed towards a multi-connectivity framework that supports the operation of new radio (NR, sometimes referred to as 5G). As will be understood, by reducing the use of signals with some bands in some circumstances, one or more embodiments can provide benefits including, system robustness and increased confidence in the safety of the operation of the network.
It should be understood that any of the examples and terms used herein are non-limiting. For instance, while examples are generally directed to identifying potential interference by certain wireless communication bands with aircraft operations, it should be understood that it is straightforward to extend the technology described herein to other scenarios where interference can be caused by different signal bands. As such, any of the examples herein are non-limiting examples, any of the embodiments, aspects, concepts, structures, functionalities or examples described herein are non-limiting, and the technology may be used in various ways that provide benefits and advantages in radio communications in general.
In some embodiments, understandable variations of the non-limiting terms “signal propagation source equipment” or simply “propagation equipment,” “radio network node” or simply “network node,” “radio network device,” “network device,” and access elements are used herein. These terms may be used interchangeably and refer to any type of network node that can serve user equipment and/or be connected to other network node or network element or any radio node from where user equipment can receive a signal. Examples of radio network node include, but are not limited to, base stations (BS), multi-standard radio (MSR) nodes such as MSR BS, gNode B (gNB), eNode B (eNB), network controllers, radio network controllers (RNC), base station controllers (BSC), relay, donor node controlling relay, base transceiver stations (BTS), access points (AP), transmission points, transmission nodes, remote radio units (RRU) (also termed radio units herein), remote ratio heads (RRH), and nodes in distributed antenna system (DAS). Additional types of nodes are also discussed with embodiments below, e.g., donor node equipment and relay node equipment, an example use of these being in a network with an integrated access backhaul network topology.
In some embodiments, understandable variations of the non-limiting term user equipment (UE) are used. This term can refer to any type of wireless device that can communicate with a radio network node in a cellular or mobile communication system. Examples of UEs include, but are not limited to, a target device, device to device (INSTRUCTION COMPONENTD) user equipment, machine type user equipment, user equipment capable of machine to machine (M2M) communication, PDAs, tablets, mobile terminals, smart phones, laptop embedded equipped (LEE), laptop mounted equipment (LME), USB dongles, and other equipment that can have similar connectivity. Example UEs are described further with
One having skill in the relevant art(s), given the disclosure herein understands that the computer processing systems, computer-implemented methods, equipment (apparatus) and/or computer program products described herein employ hardware and/or software to solve problems that are highly technical in nature (e.g., determining that some certain bands are to be limited in some circumstances), that are not abstract and cannot be performed as a set of mental acts by a human. For example, a human, or even a plurality of humans, cannot efficiently monitor use of complex user equipment signaling (e.g., MIMO operations) and alter the use of certain signals, with the same level of accuracy and/or efficiency as the various embodiments described herein.
Aspects of the subject disclosure will now be described more fully hereinafter with reference to the accompanying drawings in which example components, graphs and selected operations are shown. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the various embodiments. For example, some embodiments described can facilitate, based on a determination that a user equipment is operating from an airborne aircraft, limiting the use signals with potentially interfering bands. Different examples that describe these aspects are included with the description of
Airborne user equipment 155 is depicted as operating in airborne aircraft 187. As is discussed further herein, airborne aircraft 187 is a non-limiting example of a location where a user equipment can be operated substantially above ground level, e.g., by a drone with mobile connectivity, an aircraft such as a helicopter or airplane, a structure (e.g., a building) where a user equipment is operated.
Interference controller equipment 150 can include computer executable components 120, processor 160, storage device 162 and memory 165. Computer executable components 120 can include altitude component 122, instruction component 124, communication component 126, and other components described or suggested by different embodiments described herein, that can improve the operation of system 100.
Storage device 162 can include bands list 167, which, in different implementations, can include a subset of available bands in serving sites of the communications network. This subset can include bands that can potentially interfere with other signals in a particular area. Nonlimiting examples of bands list 167 used by one or more embodiments described herein can include bands that can interfere with the operation of aircraft, e.g., some of the so-called C-band spectrum is thought by some analysts to have the potential to interfere with the operation of some instruments of large airplanes, e.g., radio altimeter operation. As 5G operation becomes more prevalent, the new bands used by 5G MIMO devices represent new potentially interfering bands to be handled by one or more embodiments.
Different areas that can be covered in bands list 167 as potentially interfering with other signals include user equipment operating at altitudes where their signal is spread beyond the normal distribution of ground-based user equipment, e.g., when a user equipment (or a drone with UE capabilities) is operating from an altitude comparable to a base station tower, the user equipment can broadcast signals to a wide area like the base station tower.
In one or more embodiments, bands list can be pre-loaded and relatively static, or dynamically altered based on analysis of usage data, e.g., adjusted based on artificial intelligence, such as is discussed with
Further to the above, it should be appreciated that these components, as well as aspects of the embodiments of the subject disclosure depicted in this figure and various figures disclosed herein, are for illustration only, and as such, the architecture of such embodiments are not limited to the systems, devices, and/or components depicted therein.

Further examples of memory 165 are described below with reference to system memory 1006 and
According to multiple embodiments, storage device 162 can include, but is not limited to, RAM, ROM, EEPROM, flash memory or other memory technology, solid state drive (SSD) or other solid-state storage technology, Compact Disk Read Only Memory (CD ROM), digital video disk (DVD), blu-ray disk, or other optical disk storage, magnetic cassettes, magnetic tape, magnetic disk storage or other magnetic storage devices, or any other medium which can be used to store the desired information and which can be accessed by the computer.

Further, in another example, in one or more embodiments, computer executable components 120 can include instructions that, when executed by processor 160, can facilitate performance of operations defining instruction component 124. As discussed with
In yet another example, computer executable components 120 can include instructions that, when executed by processor 160, can facilitate performance of operations defining communication component 126. As discussed herein, in one or more embodiments, communication component 126 can communicate the signal limiting instruction to alter the signal associated with the user equipment with respect to a potentially interfering bands. For example, one or more embodiments can communicate the signal limiting instruction 172 to alter the signal associated with the user equipment with respect to a potentially interfering bands, as specified by bands list 167 discussed above.
As depicted, system 200 can include UE 155 connected to interference controller equipment 150 via base station 295. In one or more embodiments, UE 155 can include memory 265 that can store one or more computer and/or machine readable, writable, and/or executable components and/or instructions 220 that, when respectively executed by processor 260, can facilitate performance of operations defined by the executable component(s) and/or instruction(s).
In system 200, computer executable components 220 can include altitude component 212, instruction component 214, signal altering component 216, and other components described or suggested by different embodiments described herein that can improve the operation of system 200. For example, in some embodiments, UE 155 can further include various computer and/or computing-based elements described herein with reference to mobile handset 900 of
In one or more embodiments, computer executable components 220 can be used in connection with implementing one or more of the systems, devices, components, and/or computer-implemented operations shown and described in connection with
In another example, in one or more embodiments, computer executable components 220 can include instructions that, when executed by processor 260, can facilitate performance of operations defining instruction component 214. As discussed below, instruction component 214 can, in accordance with one or more embodiments, identify an instruction that is related to a signal bands, with the instruction being generated based on a determination, based on the altitude, that a signal of the signal bands has at least a threshold likelihood of interfering with a modality of transport.
In another example, in one or more embodiments, computer executable components 220 can include instructions that, when executed by processor 260, can facilitate performance of operations defining signal altering component 216. As discussed below, instruction component 216 can, in accordance with one or more embodiments, based on the instruction, alter use of the signal bands for transmission by the user equipment. In an example, based on the altitude of UE 155 and bands list 167, interference controller equipment 150 can alter the use of certain bands by UE 155, e.g., by instruction 172.
As depicted, system 300 shows aircraft 390A-B operating at altitudes 340A-B respectively, with example UEs on board (not shown). Structure 375 includes high-rise user equipment 377 operating at altitude 340C. Aircraft 390A is depicted as operating above high-altitude threshold 315 and both aircraft 390B and high-rise user equipment 377 are depicted operating between medium altitude threshold 316 and high-altitude threshold 315. Serving site tower 310 is depicted as having a transmission element operating below medium altitude threshold 316.
At 410, the bands list can be read to facilitate analysis of the potential interference. As noted above, this table can be specific to a particular area, and describes not only particular bands that have the potential to interfere with other signals, but also parameters to apply to limit the potential interference of the listed bands when using the bands is permitted.
At 420, Z axis elevation (e.g., altitude above sea level) 420 is determined. As noted above, one approach to determining the transmitting altitude of a user equipment is to use the GPS capabilities of the user equipment to determine the altitude. As noted, the development of enhanced emergency calling (e.g., 911) capabilities has improve this altitude estimate (e.g., also termed Z axis elevation) for some devices.
As noted with
One way that altitude component 222 can estimate the altitude of UE 155 is by using the GPS of UE 155 to identify altitude and velocity. In some circumstances however, because of certain circumstances (e.g., being inside of airborne aircraft 190A-B) an accurate GPS signal is not available. In these circumstances other user device sensors (e.g., discussed with
Another way that one or more embodiments can facilitate UE 155 determining an airborne status (e.g., without a network connection or GPS signal) is to detect signals from high altitude signal sources that have characteristics associated with a high-altitude receiver receiving a signal transmitted at a high altitude. Example characteristics include UE 155 detecting several network serving sites (e.g., serving site tower 310) at strong signal levels and low reference signal received quality. UE 155 can interpret these characteristics as evidence that the signals have arrived at line-of-sight propagation, e.g., instead of being received at ground level with Rayleigh scattering. One or more embodiments can determine elevation of user equipment my identifying that the UE has received line-of-sight transmissions from a tower at an example two-hundred (200) foot height.
In one or more embodiments, high-rise user equipment 377 is being operated from structure 375. One or more embodiments can use one or more of the other approaches described herein to determine that high-rise user equipment is at a height where interference can cause problems.
Another approach that can be used to determine the interference potential of UE 155 is by configuring an aircraft to emit positioning information with a repeater/transmitter that is internal to the aircraft, e.g., GPS, WiFi, Femto. In this circumstance, instead of GPS or interference controller equipment 150 connectivity, one or more embodiments can receive information broadcast by the aircraft that provides interference potential information, e.g., the position notifier can be integrated with avionics (i.e., radio altimeter) so that UE 155 can be disabled from C band while certain aircraft instruments are in use.
At 430, the determined altitude is compared to a high-altitude threshold 315. In some circumstances, high-altitude threshold 315 can be set to a distance above which interference would likely be so significant that use of potentially interfering bands is set to be preemptively disabled 450, e.g., before use of the bands, and before notice or detection of any interference by signals of the bands. In an example implementation, this high-altitude threshold is two hundred (200) feet above sea level, an example aircraft 190A depicted as operating above this threshold.
Alternatively, when the elevation is not above high-altitude threshold 315 (e.g., 435) a middle threshold value is compared to the altitude. In one or more embodiments, because of the lower potential interference from the identified bands, transmission of signals with these bands are not disabled. Instead, the transmission is altered, e.g., to reduce the potential of interference based on the altitude by issuing an instruction 172 that can limit the potential for interference. In an example, the instruction 172 used to limit the potential for interference is a power instruction that can reduce a transmission power of the transmission of the signal using the potentially interfering bands. In another example instruction 172, the instruction can be an interval instruction that reduces a transmission time interval (TTI) allocated to the user equipment for the transmission of the signal using the potentially interfering bands. In yet another example, instruction 172 can limit the potential by reducing a size of a physical resource block (PRB) allocated for the transmission of the signal using the potentially interfering bands. One having skill in the relevant art(s), given the description herein, appreciates that other approaches can be implemented in 5G and LTE radio access technologies to reduce the likelihood of interference in circumstances described herein.
At 470, a timer can be checked to determine whether an interference check can be paused (e.g., to save battery, if needed). If, at 475, this timer has expired then a check is made to determine whether a recheck 480 is selected.
As depicted, system 500 can include interference prediction component 524, historical data store 525, training data 595, and interference prediction model 510. Interference prediction component 524 in this example can include artificial neural network (ANN) 575, ANN training model 572, and regression analysis component 590.
In certain embodiments, different functions of interference predicting component 524 can be facilitated based on classifications, correlations, inferences and/or expressions associated with principles of artificial intelligence and machine learning. For example, interference predicting component 524 can employ expert systems, fuzzy logic, SVMs, Hidden Markov Models (HMMs), greedy search algorithms, rule-based systems, Bayesian models (e.g., Bayesian networks), ANNs, other non-linear training techniques, data fusion, utility-based analytical systems, systems employing Bayesian models, and ensemble ML algorithms/methods, comprising deep neural networks (DNN), reinforcement learning (RL), Bayesian Statistics, long short-term memory (LSTM) networks. One or more of the above approaches can be specified in capacity prediction model 510 can be used by capacity prediction component 370 to analyze one or more sources of network usage information discussed above.
In an example embodiment, the historical data store 525 can be included in information stored in ANN 575, that was trained by historical information associated with the interference controller equipment 150. In additional embodiments, initial and subsequent training of ANN 575 can be based on collected production data stored in historical data store 525 that has been divided into training data 595 in a first data portion and optimizing data (e.g., testing, validation) in a second portion of data. In different approaches, these portions can be selected based on different approaches that can include, but are not limited to, a random or pseudorandom selection process.
As would be appreciated by one having skill in the relevant art(s), given the description herein, different aspects of network data records (e.g., results of one or more embodiments with respect to interference by certain bands) can be used to train ANN 575. Example values that can be assessed can include, bands utilization, quality of service metrics such as key performance indicators (KPIs) and key quality indicators (KQI), performance and configuration data collected by UE/eNodeB, along with different scenarios of interference detected and reported.
As would be appreciated by one having skill in the relevant art(s), given the description herein, after training by the first portion of data, the second portion of data, analysis results for the data, can be used to validate and update ANN 575, if needed. It should be noted that this description of employing an ANN is non-limiting, e.g., one or more embodiments can use other types of artificial intelligence and machine learning algorithms that receive input and perform capacity analysis as described above.
In another approach, machine learning (supervised learning) based solutions to analyze the types of data described above to generate predicted interference by different bands. As would be appreciated by one having skill in the relevant art(s), given the description herein, regression analysis component 590 can be used to apply a regression analysis approach to machine learning for embodiments, e.g., this approach being useful in some circumstances for analyzing data to generate different improved solutions to a problem.

This function supports the indoor radio link, such as IEEE 802.11, for the dual-mode GSM handset 900. The handset 900 can accommodate at least satellite radio services through a handset that can combine wireless voice and digital radio chipsets into a single handheld device.
Network 190 can employ various cellular systems, technologies, and modulation schemes to facilitate wireless radio communications between devices. While example embodiments include use of 5G new radio (NR) systems, one or more embodiments discussed herein can be applicable to any radio access technology (RAT) or multi-RAT system, including where user equipment operate using multiple carriers, e.g., LTE FDD/TDD, GSM/GERAN, CDMA2000, etc. For example, wireless communication system 200 can operate in accordance with global system for mobile communications (GSM), universal mobile telecommunications service (UMTS), long term evolution (LTE), LTE frequency division duplexing (LTE FDD, LTE time division duplexing (TDD), high speed packet access (HSPA), code division multiple access (CDMA), wideband CDMA (WCMDA), CDMA2000, time division multiple access (TDMA), frequency division multiple access (FDMA), multi-carrier code division multiple access (MC-CDMA), single-carrier code division multiple access (SC-CDMA), single-carrier FDMA (SC-FDMA), orthogonal frequency division multiplexing (OFDM), discrete Fourier transform spread OFDM (DFT-spread OFDM) single carrier FDMA (SC-FDMA), Filter bank based multi-carrier (FBMC), zero tail DFT-spread-OFDM (ZT DFT-s-OFDM), generalized frequency division multiplexing (GFDM), fixed mobile convergence (FMC), universal fixed mobile convergence (UFMC), unique word OFDM (UW-OFDM), unique word DFT-spread OFDM (UW DFT-Spread-OFDM), cyclic prefix OFDM CP-OFDM, resource-block-filtered OFDM, Wi Fi, WLAN, WiMax, and the like. However, various features and functionalities of system 100 are particularly described wherein the devices of system 100 are configured to communicate wireless signals using one or more multi carrier modulation schemes, wherein data symbols can be transmitted simultaneously over multiple frequency subcarriers (e.g., OFDM, CP-OFDM, DFT-spread OFMD, UFMC, FMBC, etc.). The embodiments are applicable to single carrier as well as to multicarrier (MC) or carrier aggregation (CA) operation of the user equipment. The term carrier aggregation (CA) is also called (e.g., interchangeably called) “multi-carrier system”, “multi-cell operation”, “multi-carrier operation”, “multi-carrier” transmission and/or reception. Note that some embodiments are also applicable for Multi RAB (radio bearers) on some carriers (that is data plus speech is simultaneously scheduled).
Various embodiments described herein can be configured to provide and employ 5G wireless networking features and functionalities. With 5G networks that may use waveforms that split the bands into several sub bands, different types of services can be accommodated in different sub bands with the most suitable waveform and numerology, leading to improved spectrum utilization for 5G networks. Notwithstanding, in the mmWave spectrum, the millimeter waves have shorter wavelengths relative to other communications waves, whereby mmWave signals can experience severe path loss, penetration loss, and fading. However, the shorter wavelength at mmWave frequencies also allows more antennas to be packed in the same physical dimension, which allows for large-scale spatial multiplexing and highly directional beamforming.
Generally, program modules include routines, programs, components, data structures, etc., that perform particular tasks or implement particular abstract data types. Moreover, those skilled in the art will appreciate that the various methods can be practiced with other computer system configurations, including single-processor or multiprocessor computer systems, minicomputers, mainframe computers, Internet of Things (IoT) devices, distributed computing systems, as well as personal computers, hand-held computing devices, microprocessor-based or programmable consumer electronics, and the like, each of which can be operatively coupled to one or more associated devices.

In this regard, the terms “tangible” or “non-transitory” herein as applied to storage, memory or computer-readable media, are to be understood to exclude only propagating transitory signals per se as modifiers and do not relinquish rights to all standard storage, memory or computer-readable media that are not only propagating transitory signals per se.
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.
With reference again to
The system bus 1008 can be any of several types of bus structure that can 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 1006 includes ROM 1010 and RAM 1012. A basic input/output system (BIOS) can be stored in a non-volatile memory such as ROM, erasable programmable read only memory (EPROM), EEPROM, which BIOS contains the basic routines that help to transfer information between elements within the computer 1002, such as during startup. The RAM 1012 can also include a high-speed RAM such as static RAM for caching data.
The computer 1002 further includes an internal hard disk drive (HDD) 1014 (e.g., EIDE, SATA), one or more external storage devices 1016 (e.g., a magnetic floppy disk drive (FDD) 1016, a memory stick or flash drive reader, a memory card reader, etc.) and a drive 1020, e.g., such as a solid-state drive, an optical disk drive, which can read or write from a disk 1022, such as a CD-ROM disc, a DVD, a BD, etc. Alternatively, where a solid-state drive is involved, disk 1022 would not be included, unless separate. While the internal HDD 1014 is illustrated as located within the computer 1002, the internal HDD 1014 can also be configured for external use in a suitable chassis (not shown). Additionally, while not shown in environment 1000, a solid-state drive (SSD) could be used in addition to, or in place of, an HDD 1014. The HDD 1014, external storage device(s) 1016 and drive 1020 can be connected to the system bus 1008 by an HDD interface 1024, an external storage interface 1026 and a drive interface 1028, respectively. The interface 1024 for external drive implementations can include at least one or both of Universal Serial Bus (USB) and Institute of Electrical and Electronics Engineers (IEEE) 1394 interface technologies. Other external drive connection technologies are within contemplation of the embodiments described herein.
The drives and their associated computer-readable storage media provide nonvolatile storage of data, data structures, computer-executable instructions, and so forth. For the computer 1002, the drives and storage media accommodate the storage of any data in a suitable digital format. Although the description of computer-readable storage media above refers to respective types of storage devices, it should be appreciated by those skilled in the art that other types of storage media which are readable by a computer, whether presently existing or developed in the future, could also be used in the example operating environment, and further, that any such storage media can contain computer-executable instructions for performing the methods described herein.
A number of program modules can be stored in the drives and RAM 1012, including an operating system 1030, one or more application programs 1032, other program modules 1034 and program data 1036. All or portions of the operating system, applications, modules, and/or data can also be cached in the RAM 1012. The systems and methods described herein can be implemented utilizing various commercially available operating systems or combinations of operating systems.
Computer 1002 can optionally comprise emulation technologies. For example, a hypervisor (not shown) or other intermediary can emulate a hardware environment for operating system 1030, and the emulated hardware can optionally be different from the hardware illustrated in
Further, computer 1002 can be enable with a security module, such as a trusted processing module (TPM). For instance, with a TPM, boot components hash next in time boot components, and wait for a match of results to secured values, before loading a next boot component. This process can take place at any layer in the code execution stack of computer 1002, e.g., applied at the application execution level or at the operating system (OS) kernel level, thereby enabling security at any level of code execution.
A user can enter commands and information into the computer 1002 through one or more wired/wireless input devices, e.g., a keyboard 1038, a touch screen 1040, and a pointing device, such as a mouse 1042. Other input devices (not shown) can include a microphone, an infrared (IR) remote control, a radio frequency (RF) remote control, or other remote control, a joystick, a virtual reality controller and/or virtual reality headset, a game pad, a stylus pen, an image input device, e.g., camera(s), a gesture sensor input device, a vision movement sensor input device, an emotion or facial detection device, a biometric input device, e.g., fingerprint or iris scanner, or the like. These and other input devices are often connected to the processing unit 1004 through an input device interface 1044 that can be coupled to the system bus 1008, but can be connected by other interfaces, such as a parallel port, an IEEE 1394 serial port, a game port, a USB port, an IR interface, a BLUETOOTH® interface, etc.
A monitor 1046 or other type of display device can be also connected to the system bus 1008 via an interface, such as a video adapter 1048. In addition to the monitor 1046, a computer typically includes other peripheral output devices (not shown), such as speakers, printers, etc.
The computer 1002 can operate in a networked environment using logical connections via wired and/or wireless communications to one or more remote computers, such as a remote computer(s) 1050. The remote computer(s) 1050 can be a workstation, a server computer, a router, a personal computer, portable computer, microprocessor-based entertainment appliance, a peer device or other common network node, and typically includes many or all of the elements described relative to the computer 1002, although, for purposes of brevity, only a memory/storage device 1052 is illustrated. The logical connections depicted include wired/wireless connectivity to a local area network (LAN) 1054 and/or larger networks, e.g., a wide area network (WAN) 1056. Such LAN and WAN networking environments are commonplace in offices and companies, and facilitate enterprise-wide computer networks, such as intranets, all of which can connect to a global communications network, e.g., the Internet.
When used in a LAN networking environment, the computer 1002 can be connected to the local network 1054 through a wired and/or wireless communication network interface or adapter 1058. The adapter 1058 can facilitate wired or wireless communication to the LAN 1054, which can also include a wireless access point (AP) disposed thereon for communicating with the adapter 1058 in a wireless mode.
When used in a WAN networking environment, the computer 1002 can include a modem 1060 or can be connected to a communications server on the WAN 1056 via other means for establishing communications over the WAN 1056, such as by way of the Internet. The modem 1060, which can be internal or external and a wired or wireless device, can be connected to the system bus 1008 via the input device interface 1044. In a networked environment, program modules depicted relative to the computer 1002 or portions thereof, can be stored in the remote memory/storage device 1052. It will be appreciated that the network connections shown are example and other means of establishing a communications link between the computers can be used.
When used in either a LAN or WAN networking environment, the computer 1002 can access cloud storage systems or other network-based storage systems in addition to, or in place of, external storage devices 1016 as described above, such as but not limited to a network virtual machine providing one or more aspects of storage or processing of information. Generally, a connection between the computer 1002 and a cloud storage system can be established over a LAN 1054 or WAN 1056 e.g., by the adapter 1058 or modem 1060, respectively. Upon connecting the computer 1002 to an associated cloud storage system, the external storage interface 1026 can, with the aid of the adapter 1058 and/or modem 1060, manage storage provided by the cloud storage system as it would other types of external storage. For instance, the external storage interface 1026 can be configured to provide access to cloud storage sources as if those sources were physically connected to the computer 1002.
The computer 1002 can be operable to communicate with any wireless devices or entities operatively disposed in wireless communication, e.g., a printer, scanner, desktop and/or portable computer, portable data assistant, communications satellite, any piece of equipment or location associated with a wirelessly detectable tag (e.g., a kiosk, news stand, store shelf, etc.), and telephone. This can include Wireless Fidelity (Wi-Fi) and BLUETOOTH® wireless technologies. Thus, the communication can be a predefined structure as with a conventional network or simply an ad hoc communication between at least two devices.
The above description of illustrated embodiments of the subject disclosure, including what is described in the Abstract, is not intended to be exhaustive or to limit the disclosed embodiments to the precise forms disclosed. While specific embodiments and examples are described herein for illustrative purposes, various modifications are possible that are considered within the scope of such embodiments and examples, as those skilled in the relevant art can recognize.
In this regard, while the disclosed subject matter has been described in connection with various embodiments and corresponding Figures, where applicable, it is to be understood that other similar embodiments can be used or modifications and additions can be made to the described embodiments for performing the same, similar, alternative, or substitute function of the disclosed subject matter without deviating therefrom. Therefore, the disclosed subject matter should not be limited to any single embodiment described herein, but rather should be construed in breadth and scope in accordance with the appended claims below.
Further to the description above, 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 may also be implemented as a combination of computing processing units.
In the subject specification, terms such as “store,” “storage,” “data store,” data storage,” “database,” 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.
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 and not limitation, 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. In addition, these components can execute from various computer readable media, device readable storage devices, or machine-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.
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.
Additionally, the terms “core-network”, “core”, “core carrier network”, “carrier-side”, 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. User equipment 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; 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 disclosure 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.
While the various embodiments are susceptible to various modifications and alternative constructions, certain illustrated implementations thereof are shown in the drawings and have been described above in detail. It should be understood, however, that there is no intention to limit the various embodiments to the specific forms disclosed, but on the contrary, the intention is to cover all modifications, alternative constructions, and equivalents falling within the spirit and scope of the various embodiments.
In addition to the various implementations described herein, it is to be understood that other similar implementations can be used, or modifications and additions can be made to the described implementation(s) for performing the same or equivalent function of the corresponding implementation(s) without deviating therefrom. Still further, multiple processing chips or multiple devices can share the performance of one or more functions described herein, and similarly, storage can be affected across a plurality of devices. Accordingly, the embodiments are not to be limited to any single implementation, but rather are to be construed in breadth, spirit and scope in accordance with the appended claims.
