The subject disclosure relates to selectively streaming media, such as video, while conserving network resources.
With the wide adoption of video capturing devices, such as smartphones, millions of videos are generated and made available for streaming every day. These devices are also connected to the Internet, making them a convenient place to stream and consume video content online. Together with traditional video content, such as movies and TV shows, Internet based video streaming has generated a significant portion of today's Internet traffic. Together with the popularity of video streaming services, several business models have been proposed. In advertisement (AD) supported video on demand (VOD) streaming services, some ADs are skippable, which gives users an option to skip the video AD after a certain duration (e.g. a few seconds).
Reference will now be made to the accompanying drawings, which are not necessarily drawn to scale, and wherein:
The subject disclosure describes, among other things, illustrative embodiments for selectively streaming media, such as video, while conserving network resources. Other embodiments are described in the subject disclosure.
One or more aspects of the subject disclosure include a mobile device, comprising: a user interface; a wireless communications transceiver; a processor in communication with the user interface and the transceiver; and a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations. The operations may comprise receiving a request for media content through the user interface and transmitting a request for the media content through the transceiver. The operations may comprise retrieving a first portion of a preceding media, such as an AD through the transceiver and presenting the first portion of the preceding media through the user interface. The operations may comprise determining whether a second portion of the preceding media is skippable. If the second portion of the preceding media is not skippable, the operations may comprise retrieving the second portion of the preceding media and presenting the second portion of the preceding media without constraints. If the second portion of the preceding media is skippable, the operations may comprise determining whether a skip request is received through the user interface. If the skip request has not been received, the operations may comprise retrieving the second portion of the preceding media imposing constraints and presenting the second portion of the preceding media. If the skip request has been received, the operations may comprise ceasing retrieval of the second portion of the preceding media, retrieving the media content, and presenting the media content through the user interface.
The constraint may be downloading a limited part of the second portion of the preceding media. For example, downloading the limited part of the second portion of the preceding media may comprise waiting to download a next segment of the second portion of the preceding media until an immediately preceding segment of the second portion of the preceding media begins to play. Thus, the first portion of the preceding media and the media content may be received at the mobile device in their entirety. But, if the skip request is received, at least part of the second portion of the preceding media need not be received at the mobile device.
One or more aspects of the subject disclosure include a method comprising: determining whether a skippable media is being streamed; responsive to determining that the skippable media is being streamed, determining, by the processing system, a skip point in the skippable media; streaming, by the processing system, a first portion of the skippable media without imposing a constraint, wherein the first portion of the skippable media precedes the skip point; and streaming, by the processing system, a second portion of the skippable media while imposing the constraint, wherein the second portion of the skippable media follows the skip point.
The constraint may be downloading a limited part of the second portion. For example, downloading the limited part of the second portion may comprise waiting to download a next segment of the second portion of the skippable media until an immediately preceding segment of the skippable media begins to play. The next segment of the second portion of the skippable media need not be downloaded if a request to skip is received.
Streaming the second portion of the skippable media while imposing the constraint may comprise downloading a next segment of the second portion of the skippable media while an immediately preceding segment of the skippable media is playing. The next segment of the second portion of the skippable media need not be downloaded until a threshold is met, wherein the threshold specifies a maximum amount of time remaining to be played of the immediately preceding segment of the skippable media. The next segment of the second portion of the skippable media need not be downloaded if a request to skip is received before the threshold is met.
In some embodiments, each segment of the second portion of the skippable media spans at least a time period and the maximum amount of time specified by the threshold is less than that time period. In some embodiments, the maximum amount of time specified by the threshold is less than half of that time period.
In some embodiments, streaming the second portion of the skippable media while imposing the constraint comprises waiting to download a next segment until most of an immediately preceding segment of the skippable media has been played. Streaming the second portion of the skippable media may be terminated upon receiving a request to skip.
In some embodiments, each segment of the second portion of the skippable media spans at least a time period and streaming the second portion of the skippable media while imposing the constraint comprises downloading a next segment fraction of the skippable media while an immediately preceding segment fraction of the skippable media is playing. The next segment fraction may be shorter than the time period.
One or more aspects of the subject disclosure include a server, comprising: a processing system including a processor; and a memory that stores executable instructions that, when executed by the processing system, facilitate performance of operations, the operations comprising: receiving a request for media content from a mobile device; retrieving a first portion of an AD and sending the first portion of the AD to the mobile device without imposing a constraint; determining whether the AD includes a skippable portion. If the AD does not include the skippable portion, the operations may comprise retrieving a second portion of the AD and sending the second portion of the AD to the mobile device without imposing the constraint. If the AD includes the skippable portion, the operations may comprise retrieving the second portion of the AD and sending the second portion of the AD to the mobile device imposing the constraint. If a request to skip the AD is received, the operations may comprise ceasing the retrieving the second portion of the AD. The operations may comprise retrieving the media content and sending the media content to the mobile device without imposing the constraint.
The constraint may comprise downloading a limited part of the second portion of the AD. For example, downloading the limited part of the second portion of the AD may comprise waiting to download a next segment of the second portion of the AD until an immediately preceding segment of the second portion of the AD begins to play. Thus the first portion of the AD and the media content may be received at the mobile device in their entirety. But, if the request to skip the AD is received, at least part of the second portion of the AD need not be received at the mobile device.
Video streaming has become very popular in the last decade and has generated a significant portion of today's Internet traffic. While there are different business models for video streaming services, AD-supported online VOD streaming has attracted a very large number of users, at least partially due to the free use of video content. However, users usually need to watch AD(s) before the requested video starts playing. In general, there are two types of video ADs: skippable and non-skippable. The former gives users an option to skip the video AD after a certain duration (e.g. a few seconds). This may lead to network bandwidth wastage when video ADs can be fetched quickly, for example under 4G LTE networks and 5G networks. By the time a user can skip the video AD, a very large portion or even the whole video AD may have already been downloaded. Such downloaded and skipped AD content is a waste of both provider's network resource and user's network data plan.
We propose a novel method and system that can reduce network bandwidth usage during video AD streaming, under the “skippable video AD” scenario. Broadly speaking, our method consists of two phases: detecting “skippable video AD” and reducing network bandwidth usage. The detection phase may use screen analysis and/or machine learning at user equipment (UE) and/or on the network to identify whether a current video AD can be skipped and the required duration. Then, the reduction phase may leverage intelligence at the UE and/or on the network to control the downloading of video AD. For example, some embodiments download just enough of a video AD for playback before the required duration times out (e.g. if the user is eligible to skip AD in 5 seconds, some embodiments need only download 5 seconds worth of AD content).

Some embodiments may be based on large-scale data collection and machine learning on the network, such as at middle boxes. First, UE may perform skippable video AD detection using a local detection method. Then, the UE may send the video AD identifier (e.g. its URL) and its associated metadata, such as “skippable in X seconds” or “non-skippable”, as training data to a middle box or other network element. As more and more training data is collected, network elements can learn a prediction algorithm, perform classification for future video AD, and notify a UE directly on whether the AD is skippable or not and/or its required duration. In this way, UE need not perform local video AD detection at all.

The content sources 175 and or the network elements 150, 152, 154, 156 may precede the media content with one or more ADs. Advertisers, who pay to have their ADs thus inserted, may specify how much of the AD must be watched in order for any such payment to become due. These advertisers may also require user input before skipping any skippable portion of their ADs. For this reason, most content/network providers do not simply automatically skip ADs or portions thereof.
The method 200 described herein may be performed in whole, or in part, by any of the access terminal 112, the data terminals 114, the mobile devices 124, the vehicle 126, the media terminal 142, the display devices 144, the network elements 150, 152, 154, 156 and/or the content sources 175 discussed above. For example, the method 200 described herein may be distributed across any of the access terminal 112, the data terminals 114, the mobile devices 124, the vehicle 126, the media terminal 142, the display devices 144, the network elements 150, 152, 154, 156 and/or the content sources 175 discussed above. The method 200 described herein may be embodied by a machine-readable medium comprising executable instructions that, when executed by a processor, facilitate performance thereof, by any of the access terminal 112, the data terminals 114, the mobile devices 124, the vehicle 126, the media terminal 142, the display devices 144, the network elements 150, 152, 154, 156 and/or the content sources 175 discussed above.
As shown in 202, the method may begin by receiving a request for media content from a user, such as through their UE, which may forward that request, or send another request, to the network elements 150, 152, 154, 156 and/or the content sources 175 discussed above. As discussed above, the network elements 150, 152, 154, 156 and/or the content sources 175 may insert an AD in front of the requested media content, and begin retrieving that AD and sending that AD to the UE, as shown in 204. The UE may begin presenting the AD as soon as it begins being retrieved, or received, at the UE.
As shown in 206, the UE, the network elements 150, 152, 154, 156 and/or the content sources 175 may attempt to determine whether the AD is skippable, or contains a skippable portion. This may be done at the UE, such as by screen capture, text recognition, and/or by another technique as described above. This may also be done at the network elements 150, 152, 154, 156 and/or the content sources 175, such as by analyzing metadata, a source of the AD, previous experience with the AD, and/or by another technique as described above. For example, the metadata may indicate that the AD is skippable and/or a skip point in the AD, after which the AD is skippable. More specifically, the metadata may indicate that the AD is thirty (30) seconds long and may be skipped after the first five (5) seconds. In this example, the skip point would be five (5) seconds into the AD. Skip points at other times, such as two, four, ten, or fifteen seconds are also contemplated.
Some advertisers, or AD sources, may indicate that their AD is skippable and/or a skip point in the AD. Prior experience may indicate that an AD is skippable and/or a skip point in the AD. For example, if a portion of prior users have previously skipped a portion of the AD, then the system or device implementing the method 200 may presume that the AD is skippable and/or a skip point in the AD. More specifically, the greater the portion of prior users that have previously skipped a portion of the AD, the more likely that portion of the AD is skippable in the present instance.
If the AD is skippable, or contains a skippable portion, in 206, the system or device implementing the method 200 continues to retrieve and/or present the AD up to and including the skip point, normally, without imposing special/additional constraints. Once the skip point has been reached, the system or device implementing the method 200 begins retrieving the skippable portion, post skip point, for presentation on the UE, as shown in 208. In some embodiments, the system or device implementing the method 200 begins retrieving the skippable portion during retrieval and/or presentation of the non-skippable portion, i.e. before the skip point has been reached.
In some embodiments, the skippable portion is retrieved and/or presented just as the preceding non-skippable portion, such as to maximize the user's quality of experience (QoE). In some embodiments, the skippable portion is retrieved and/or presented at a lower quality, resolution, bandwidth, and/or bit rate than the preceding non-skippable portion. In some embodiments, the skippable portion is retrieved in smaller chunks than the preceding non-skippable portion. In some embodiments, the skippable portion is retrieved using a just-in-time procedure that attempts to retrieve chunks of the skippable portion of the AD just in time for presentation on the UE. In some embodiments, this just-in-time procedure may utilize less of the UE's buffer capacity and/or other capabilities when compared with retrieval and/or presentation of the non-skippable portion of the AD and/or the requested media content itself.
The skippable portion may be retrieved imposing constraints not imposed on retrieving the non-skippable portion of the AD and/or the requested media content itself. A constraint may comprise downloading a limited part of the skippable portion of the AD at a time. For example, downloading the limited part of the skippable portion of the AD may comprise waiting to download a next segment of the skippable portion of the AD until an immediately preceding segment of the skippable portion of the AD begins to play. The next segment of the skippable portion of the AD need not be downloaded if a request to skip is received. Thus the non-skippable portion of the AD and the media content may be received at the mobile device in their entirety. But, if a request to skip the AD is received, at least part of the skippable portion of the AD need not be received at the mobile device.
It should be understood that while skippable ADs have been described, other forms of skippable media are contemplated. It should also be understood that retrieving the media may be followed by playing the media on the device, where retrieving and playing the media may be referred to as streaming the media.
Thus, a first of skippable media skippable media may be streamed without imposing constraints and a second portion of the skippable media may be streamed imposing constraints. For example, streaming the second portion of the skippable media while imposing the constraint may comprise downloading a next segment of the second portion of the skippable media while an immediately preceding segment of the skippable media is playing. The next segment of the second portion of the skippable media need not be downloaded until a threshold is met, wherein the threshold specifies a maximum amount of time remaining to be played of the immediately preceding segment of the skippable media. The next segment of the second portion of the skippable media need not be downloaded if a request to skip is received before the threshold is met.
In some embodiments, each segment of the second portion of the skippable media spans at least a time period and the maximum amount of time specified by the threshold is less than that time period. In some embodiments, the maximum amount of time specified by the threshold is less than half of that time period.
In some embodiments, streaming the second portion of the skippable media while imposing the constraint comprises waiting to download a next segment until most of an immediately preceding segment of the skippable media has been played. Streaming the second portion of the skippable media may be terminated upon receiving a request to skip.
In some embodiments, each segment of the second portion of the skippable media spans at least a time period and streaming the second portion of the skippable media while imposing the constraint comprises downloading a next segment fraction of the skippable media while an immediately preceding segment fraction of the skippable media is playing. The next segment fraction may be shorter than the time period.
Any combination of these techniques may be utilized in order to avoid wasting network and/or UE resources, in the event that the user elects to skip the skippable portion of the AD or other skippable media.
While the skippable portion is being retrieved and/or presented on the UE, after the non-skippable portion has been presented, the system or device implementing the method 200 may monitor the UE's user interface to determine whether, and if so when, the user requests to skip the skippable portion of the AD, as shown in 210. In some embodiments, the system or device implementing the method 200 may monitor the UE's user interface to determine whether the user requests to skip the skippable portion of the AD before the skip point, or during presentation of the non-skippable portion of the AD.
In any case, once a request to skip the AD is received, the system or device implementing the method 200 may cease retrieving and/or presenting the AD, as shown in 212, and retrieve the requested content for presentation on the UE, as shown in 214. In this manner, the UE need not retrieve all of the AD. For example, the UE may only need to retrieve the non-skippable portion of the AD. In some embodiments, the UE may only need to retrieve the non-skippable portion of the AD and enough of the skippable portion to give the user time to initiate the request to skip the AD. In some embodiments, the UE may only need to retrieve the non-skippable portion of the AD and enough of the skippable portion to prevent a stall of the AD presentation on the UE.
Rather than being implemented solely on ADs, the selective video streaming discussed herein may be implemented on intro sequences and/or other portions of the media content. For example, some videos may be preceded with series recaps or other introductory segments that may be skipped much as described above. In that case, the system or device implementing the method 200 may retrieve a first portion of the video without constraints, impose constraints as to quality, resolution, bandwidth, bit rate and/or buffer capacity as described herein (while monitoring for a skip request) on a second portion of the video (such as a skippable intro) and then retrieve the remainder of the video without constraints. Thus, in some embodiments, the system or device implementing the method 200 may selectively retrieve and/or stream the media content, such as video and/or audio/video AD, based on whether a portion of the video is skippable, as described herein.
It can be appreciated that if the system or device implementing the method 200 does not retrieve all of the AD, network and/or UE resources are likely preserved or otherwise reserved, especially where the user requests to skip the skippable portion of the AD. Further, where the skippable portion of the AD is retrieved at a lower quality, resolution, bandwidth, bit rate and/or utilizing less of the UE's buffer capacity, the user may be encouraged—such as by the lower quality or resolution itself—to request to skip the AD, thereby preserving network and/or UE resources. In any case, where the skippable portion of the AD is retrieved at a lower quality, resolution, bandwidth, bit rate and/or utilizing less of the UE's buffer capacity, the system or device implementing the method 200 may preserve network and/or UE resources. These preserved network and/or UE resources may be utilized to get a head-start on retrieving the requested media content. For example, while the system or device implementing the method 200 is retrieving the skippable portion of the AD, it may begin retrieving the requested media content.
If the AD is skippable, or contains a skippable portion, but the user never requests to skip the skippable portion of the AD, the system or device implementing the method 200 continues to retrieve the skippable portion of the AD for presentation on the UE, as shown in 216, and then retrieves the requested content for presentation on the UE, as shown in 214. In some embodiments, the system or device implementing the method 200 may continue to monitor the UE's user interface for a request to skip the AD, while continuing to retrieve the skippable portion of the AD for presentation on the UE. It should be appreciated that such monitoring need only be done where it is determined that the AD contains, or likely contains, a skippable portion. In some embodiments, the system or device implementing the method 200 may begin retrieving the requested content for later presentation on the UE, while continuing to retrieve the skippable portion of the AD for presentation on the UE.
As shown in 216, if the AD is not skippable, then the system or device implementing the method 200 simply continues to retrieve the AD for presentation on the UE. Upon completion of the AD, as shown in 218, the system or device implementing the method 200 retrieves the requested content for presentation on the UE, as shown in 214. Retrieving and/or presenting the requested content may be done at the highest quality, resolution, bandwidth, and/or bit rate in order to maximize QoE.
Many of the above described features may be user dependent and/or configurable. For example, a user may proactively opt out of any of the above described features. In some embodiments, a user may historically request to skip every AD as soon as is possible. In this case, the system or device implementing the method 200 may not retrieve any of the skippable portion of the AD anticipating that the user will once again provide the request to skip the AD as soon as the skip point is reached. In some embodiments, such as where a user does not historically request to skip ADs, the system or device implementing the method 200 may retrieve the skippable portion of the AD at the normal/regular quality level/resolution, but utilizing the just-in-time procedure described above to avoid potentially wasting resources, while maximizing QoE, if the user requests to skip the particular AD being retrieved. In some embodiments, such as where a user historically requests to skip ADs, not necessarily immediately, but within five (5) seconds of the skip point, the system or device implementing the method 200 may only retrieve five (5) seconds of the skippable portion of the AD, anticipating that the user will once again provide the request to skip the AD within five (5) seconds of the skip point.
Many of the above described features may be also be dependent on the AD. For example, if most users request to skip a particular AD as soon as possible, the system or device implementing the method 200 may not retrieve any of the skippable portion of the AD. Where users typically request to skip a particular AD within five (5) seconds of the skip point, the system or device implementing the method 200 may only retrieve five (5) seconds of the skippable portion of that AD. Where users typically do not request to skip a particular AD, the system or device implementing the method 200 may retrieve the skippable portion of the AD at the normal/regular quality level/resolution, but utilizing the just-in-time procedure described above to avoid potentially wasting resources.

In particular, a cloud networking architecture is shown that leverages cloud technologies and supports rapid innovation and scalability via a transport layer 350, a virtualized network function cloud 325 and/or one or more cloud computing environments 375. In various embodiments, this cloud networking architecture is an open architecture that leverages application programming interfaces (APIs); reduces complexity from services and operations; supports more nimble business models; and rapidly and seamlessly scales to meet evolving customer requirements including traffic growth, diversity of traffic types, and diversity of performance and reliability expectations.
In contrast to traditional network elements—which are typically integrated to perform a single function, the virtualized communication network employs virtual network elements (VNEs) 330, 332, 334, etc. that perform some or all of the functions of network elements 150, 152, 154, 156, etc. For example, the network architecture can provide a substrate of networking capability, often called Network Function Virtualization Infrastructure (NFVI) or simply infrastructure that is capable of being directed with software and Software Defined Networking (SDN) protocols to perform a broad variety of network functions and services. This infrastructure can include several types of substrates. The most typical type of substrate being servers that support Network Function Virtualization (NFV), followed by packet forwarding capabilities based on generic computing resources, with specialized network technologies brought to bear when general purpose processors or general purpose integrated circuit devices offered by merchants (referred to herein as merchant silicon) are not appropriate. In this case, communication services can be implemented as cloud-centric workloads.
As an example, a traditional network element 150 (shown in
In an embodiment, the transport layer 350 includes fiber, cable, wired and/or wireless transport elements, network elements and interfaces to provide broadband access 110, wireless access 120, voice access 130, media access 140 and/or access to content sources 175 for distribution of content to any or all of the access technologies. In particular, in some cases a network element needs to be positioned at a specific place, and this allows for less sharing of common infrastructure. Other times, the network elements have specific physical layer adapters that cannot be abstracted or virtualized, and might require special DSP code and analog front-ends (AFEs) that do not lend themselves to implementation as VNEs 330, 332 or 334. These network elements can be included in transport layer 350.
The virtualized network function cloud 325 interfaces with the transport layer 350 to provide the VNEs 330, 332, 334, etc. to provide specific NFVs. In particular, the virtualized network function cloud 325 leverages cloud operations, applications, and architectures to support networking workloads. The virtualized network elements 330, 332 and 334 can employ network function software that provides either a one-for-one mapping of traditional network element function or alternately some combination of network functions designed for cloud computing. For example, VNEs 330, 332 and 334 can include route reflectors, domain name system (DNS) servers, and dynamic host configuration protocol (DHCP) servers, system architecture evolution (SAE) and/or mobility management entity (MME) gateways, broadband network gateways, IP edge routers for IP-VPN, Ethernet and other services, load balancers, distributers and other network elements. Because these elements don't typically need to forward large amounts of traffic, their workload can be distributed across a number of servers—each of which adds a portion of the capability, and overall which creates an elastic function with higher availability than its former monolithic version. These virtual network elements 330, 332, 334, etc. can be instantiated and managed using an orchestration approach similar to those used in cloud compute services.
The cloud computing environments 375 can interface with the virtualized network function cloud 325 via APIs that expose functional capabilities of the VNEs 330, 332, 334, etc. to provide the flexible and expanded capabilities to the virtualized network function cloud 325. In particular, network workloads may have applications distributed across the virtualized network function cloud 325 and cloud computing environment 375 and in the commercial cloud, or might simply orchestrate workloads supported entirely in NFV infrastructure from these third party locations.

The illustrated embodiments of the embodiments herein can be also practiced in distributed computing environments where certain tasks are performed by remote processing devices that are linked through a communications network. In a distributed computing environment, program modules can be located in both local and remote memory storage devices.
Computing devices typically comprise a variety of media, which can comprise 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 comprises 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 comprise, but are not limited to, random access memory (RAM), read only memory (ROM), electrically erasable programmable read only memory (EEPROM), flash memory or other memory technology, compact disk read only memory (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.

The system bus 408 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 406 comprises ROM 410 and RAM 412. 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 402, such as during startup. The RAM 412 can also comprise a high-speed RAM such as static RAM for caching data.
The computer 402 further comprises an internal hard disk drive (HDD) 414 (e.g., EIDE, SATA), which internal HDD 414 can also be configured for external use in a suitable chassis (not shown), a magnetic floppy disk drive (FDD) 416, (e.g., to read from or write to a removable diskette 418) and an optical disk drive 420, (e.g., reading a CD-ROM disk 422 or, to read from or write to other high capacity optical media such as the DVD).

A user can enter commands and information into the computer 402 through one or more wired/wireless input devices, e.g., a keyboard 438 and a pointing device, such as a mouse 440. Other input devices (not shown) can comprise a microphone, an infrared (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 404 through an input device interface 442 that can be coupled to the system bus 408, but can be connected by other interfaces, such as a parallel port, an IEEE 1394 serial port, a game port, a universal serial bus (USB) port, an IR interface, etc.
A monitor 444 or other type of display device can be also connected to the system bus 408 via an interface, such as a video adapter 446. It will also be appreciated that in alternative embodiments, a monitor 444 can also be any display device (e.g., another computer having a display, a smart phone, a tablet computer, etc.) for receiving display information associated with computer 402 via any communication means, including via the Internet and cloud-based networks. In addition to the monitor 444, a computer typically comprises other peripheral output devices (not shown), such as speakers, printers, etc.
The computer 402 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) 448. The remote computer(s) 448 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 comprises many or all of the elements described relative to the computer 402, although, for purposes of brevity, only a remote memory/storage device 450 is illustrated. The logical connections depicted comprise wired/wireless connectivity to a local area network (LAN) 452 and/or larger networks, e.g., a wide area network (WAN) 454. 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 402 can be connected to the LAN 452 through a wired and/or wireless communication network interface or adapter 456. The adapter 456 can facilitate wired or wireless communication to the LAN 452, which can also comprise a wireless AP disposed thereon for communicating with the adapter 456.
When used in a WAN networking environment, the computer 402 can comprise a modem 458 or can be connected to a communications server on the WAN 454 or has other means for establishing communications over the WAN 454, such as by way of the Internet. The modem 458, which can be internal or external and a wired or wireless device, can be connected to the system bus 408 via the input device interface 442. In a networked environment, program modules depicted relative to the computer 402 or portions thereof, can be stored in the remote memory/storage device 450. 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.
The computer 402 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, restroom), and telephone. This can comprise 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.
Wi-Fi can allow 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 IEEE 802.11 (a, b, g, n, ac, ag, 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 can use IEEE 802.3 or Ethernet). Wi-Fi networks operate in the unlicensed 2.4 and 5 GHz radio bands 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.

As an example, in a 3GPP UMTS network, serving node(s) 516 can be embodied in serving GPRS support node(s) (SGSN).
For radio technologies that exploit packetized communication, server(s) 514 in mobile network platform 510 can execute numerous applications that can generate multiple disparate packetized data streams or flows, and manage (e.g., schedule, queue, format . . . ) such flows. Such application(s) can comprise add-on features to standard services (for example, provisioning, billing, customer support . . . ) provided by mobile network platform 510. Data streams (e.g., content(s) that are part of a voice call or data session) can be conveyed to PS gateway node(s) 518 for authorization/authentication and initiation of a data session, and to serving node(s) 516 for communication thereafter. In addition to application server, server(s) 514 can comprise utility server(s), a utility server can comprise 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 mobile network platform 510 to ensure network's operation and data integrity in addition to authorization and authentication procedures that CS gateway node(s) 512 and PS gateway node(s) 518 can enact. Moreover, provisioning server(s) can provision services from external network(s) like networks operated by a disparate service provider; for instance, WAN 550 or Global Positioning System (GPS) network(s) (not shown). Provisioning server(s) can also provision coverage through networks associated to mobile network platform 510 (e.g., deployed and operated by the same service provider), such as distributed antennas networks that enhance wireless service coverage by providing more network coverage.
It is to be noted that server(s) 514 can comprise one or more processors configured to confer at least in part the functionality of mobile network platform 510. To that end, the one or more processor can execute code instructions stored in memory 530, for example. It is should be appreciated that server(s) 514 can comprise a content manager, which operates in substantially the same manner as described hereinbefore.
In example embodiment 500, memory 530 can store information related to operation of mobile network platform 510.

Other components not shown in
The terms “first,” “second,” “third,” and so forth, as used in the claims, unless otherwise clear by context, is for clarity only and doesn't otherwise indicate or imply any order in time. For instance, “a first determination,” “a second determination,” and “a third determination,” does not indicate or imply that the first determination is to be made before the second determination, or vice versa, etc.
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 comprise both volatile and nonvolatile memory, by way of illustration, and not limitation, volatile memory, non-volatile memory, disk storage, and memory storage. Further, nonvolatile memory can be included in read only memory (ROM), programmable ROM (PROM), electrically programmable ROM (EPROM), electrically erasable ROM (EEPROM), or flash memory. Volatile memory can comprise 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.
Moreover, it will be noted that the disclosed subject matter can be practiced with other computer system configurations, comprising single-processor or multiprocessor computer systems, mini-computing devices, mainframe computers, as well as personal computers, hand-held computing devices (e.g., PDA, phone, smartphone, watch, tablet computers, netbook computers, etc.), microprocessor-based or programmable consumer or industrial electronics, and the like. The illustrated aspects can also be practiced in distributed computing environments where tasks are performed by remote processing devices that are linked through a communications network; however, some if not all aspects of the subject disclosure can be practiced on stand-alone computers. In a distributed computing environment, program modules can be located in both local and remote memory storage devices.
Some of the embodiments described herein can also employ artificial intelligence (AI) to facilitate automating one or more features described herein. The embodiments (e.g., in connection with automatically identifying acquired cell sites that provide a maximum value/benefit after addition to an existing communication network) can employ various AI-based schemes for carrying out various embodiments thereof. Moreover, the classifier can be employed to determine a ranking or priority of each cell site of the acquired network. A classifier is a function that maps an input attribute vector, x=(x1, x2, x3, x4, . . . , xn), to a confidence that the input belongs to a class, that is, f(x)=confidence (class). Such classification can employ a probabilistic and/or statistical-based analysis (e.g., factoring into the analysis utilities and costs) to determine or infer an action that a user desires to be automatically performed. A support vector machine (SVM) is an example of a classifier that can be employed. The SVM operates by finding a hypersurface in the space of possible inputs, which the hypersurface attempts to split the triggering criteria from the non-triggering events. Intuitively, this makes the classification correct for testing data that is near, but not identical to training data. Other directed and undirected model classification approaches comprise, e.g., naïve Bayes, Bayesian networks, decision trees, neural networks, fuzzy logic models, and probabilistic classification models providing different patterns of independence can be employed. Classification as used herein also is inclusive of statistical regression that is utilized to develop models of priority.
As will be readily appreciated, one or more of the embodiments can employ classifiers that are explicitly trained (e.g., via a generic training data) as well as implicitly trained (e.g., via observing UE behavior, operator preferences, historical information, receiving extrinsic information). For example, SVMs can be configured via a learning or training phase within a classifier constructor and feature selection module. Thus, the classifier(s) can be used to automatically learn and perform a number of functions, including but not limited to determining according to predetermined criteria which of the acquired cell sites will benefit a maximum number of subscribers and/or which of the acquired cell sites will add minimum value to the existing communication network coverage, etc.
