Description

CROSS-REFERENCE TO RELATED APPLICATIONS
• This application is a continuation of U.S. patent application Ser. No. 17/315,411 filed May 10, 2021, which is a continuation of U.S. patent application Ser. No. 16/388,914 filed Apr. 19, 2019 (now U.S. Pat. No. 11,039,221). All sections of the aforementioned application(s) and patent(s) are incorporated herein by reference in their entirety.
FIELD OF THE DISCLOSURE
• The subject disclosure relates to apparatuses and methods for facilitating trickplay playback of content, such as for example a playback of content by resource-constrained devices.
BACKGROUND
• Users of devices, such as set-top boxes (STBs), have become accustomed to the ability to engage in a trickplay playback of content items. For example, VCR-style commands allow a user to rewind, pause, resume, or fast-forward content during playback. Traditionally, STBs were of a relatively large physical form-factor/profile and accommodated storage (e.g., memory) capacities that enable large amounts of data or metadata to be stored therein. As a result of such large storage capacities, traditional STBs can accommodate trickplay capabilities over the entirety of a typical content item. However, as the form-factor/profile of devices (e.g., STBs, mobile devices, etc.) continues to shrink/decrease, all other conditions being equal the amount of storage capacity that is available for accommodating trickplay playback of a content item decreases.

• FIG. 2A is a block diagram illustrating an example, non-limiting embodiment of asystem200afunctioning within, or overlaid upon, the communication network ofFIG. 1 in accordance with various aspects described herein. Thesystem200amay include one or more communication devices, such as for example a first user equipment (UE)202a, afirst server206a, asecond server210a, athird server214a, a second UE218a, etc. While theservers206a,210a, and214aare shown and described separately, in some embodiments two or more of the servers may correspond to a same/common server. In some embodiments, a given server (e.g., thefirst server206a) may correspond to a management or control server, and one or more of the other servers (e.g., thesecond server210aand/or thethird server214a) may correspond to content delivery server(s).
• Thesystem200amay be used to select and distribute one or more content items, potentially in conjunction with one or more networks. In some embodiments, thesystem200amay facilitate trickplay playback on, e.g., the UE202awith respect to the one or more content items. The above-noted features are described in more detail below in connection withFIG. 2B. More generally,FIG. 2B depicts an illustrative embodiment of amethod200bin accordance with various aspects described herein.
• Inblock204b, theUE202amay receive (and thefirst server206amay transmit) an indication of one or more content items that are available to theUE202a. The content item(s) may be available to theUE202aon the basis of a license or subscription. TheUE202amay receive the indication in response to a request transmitted by the UE. For example, the request may be generated by theUE202a(or another device) in response to a user input.
• In some embodiments, the indication obtained by theUE202ainblock204bmay take one or more forms. For example, the indication may facilitate a presentation of the indication by theUE202aas, e.g., an audio rendering, an electronic programming guide (EPG), an interactive programming guide (IPG), a menu, etc., or any combination thereof.
• Inblock208b, theUE202amay transmit (an indication of) a selection of a content item. Thefirst server206amay receive the (indication of the) selection as part ofblock208b.
• Inblock212b, theUE202amay receive a first manifest file based on the selection ofblock208b. Thefirst server206amay transmit the first manifest file to theUE202aas part ofblock212b.
• The first manifest file may be pertinent to the content item that is selected as part ofblock208b. For example, the first manifest file may include data/metadata that identifies when the selected content item is available, a location where portions of the selected content item may be obtained/retrieved, etc.
• In some embodiments, the location where the selected content item may be obtained/retrieved may be identified in accordance with an address (e.g., a network address). The address may uniquely identify a first device that hosts/stores one or more portions of the selected content item from other devices. Continuing the above example, and assuming that the selected content item is stored at/by thesecond server210a(and not thethird server214a), the data/metadata of the first manifest file may identify or include the address of thesecond server210a. It should be noted, however, that in some embodiments, multiple servers may store respective portions of a content item. Still further, at least some of the portions of a content item may be replicated across multiple servers in order to promote reliability (e.g., in order to safeguard against a given server being inoperable or offline).
• In some embodiments, the first manifest file may refer to a portion (e.g., a segment or chunk) of the selected content item that is less than the whole of the selected content item. For example, the first manifest file may contain up to a threshold amount (e.g., 6 seconds) of metadata associated with a playback of the content item. The threshold amount of metadata may be selected to enable theUE202ato pre-fetch a sufficient amount of data associated with the selected content item inblock250b(described below), while reducing (e.g., minimizing) buffering-related delays during the playback. The threshold may be predetermined and/or may be adapted in response to changing/dynamic conditions (e.g., network loads, quality of service (QoS) parameters, types of communication sessions that theUE202ais engaged in, etc.).
• Inblock250b, theUE202amay obtain the data associated with the portion of the selected content item. For example, theUE202amay obtain the data associated with the portion of the selected content item in accordance with the terms/conditions imposed by the first manifest file received inblock212b. Continuing the above example, as part ofblock250btheUE202amay transmit a request to thesecond server210afor data associated with a portion of the selected content item, and thesecond server210amay transmit the data associated with the portion of the selected content item to theUE202ain response to receiving that request.
• Inblock254b, theUE202amay playback the portion of the selected content item based on the data obtained as part ofblock250b. While not shown inFIG. 2B, fromblock254bflow may proceed to, e.g., block212b. Thus, a loop may be established whereby theUE202acontinues to receive an updated version of the first manifest file from, e.g., thefirst server206a, in order to facilitate receipt of metadata by theUE202athat, when taken/viewed in the aggregate, describes/refers to multiple portions (e.g., the entirety) of the selected content item.
• Assuming that the playback of the selected content item as part ofblock254bis a linear playback (such as for example playback associated with a broadcast or multicast distribution model) then every UE that is part of thesystem200amay receive substantially the same (first) manifest file from, e.g., thefirst server206ain conjunction with that selected content item and may playback the selected content item in the manner set forth above (e.g., there may be a direct flow fromblock212bto block250bas shown via the dashed arrow inFIG. 2B that connects those blocks). Moreover, the loop described above (in respect of the flow fromblock254bto block212b) may facilitate a rolling window in terms of a respective portion of the selected content item, which is to say that as a first portion of the playback is completed that first portion (in terms of the metadata associated with the manifest file and/or in terms of the data of the selected content item itself) may be discarded of or overwritten by subsequently received data or metadata. In this manner, the size and content of the first manifest file as utilized by the UEs may the same/common across all the UEs.
• However, if trickplay capability is to be supported/facilitated, then as shown on thetimeline200cofFIG. 2C, theUE202amay initiate a first trickplay action (e.g., may initiate a pause) at afirst point202cin the playback of the selected content item, and another UE (e.g., theUE218ainFIG. 2A) may initiate a second trickplay action (e.g., may initiate a rewind, pause, resume, or fast-forward) at asecond point218cin the playback of the selected content item. While thesecond point218cis shown inFIG. 2C as a different time point relative to thefirst point202c, thesecond point218cmay be the same as thefirst point202cin some instances. Furthermore, the second trickplay action may be the same as, or different from, the first trickplay action.
• Unless every UE in a system initiated the same trickplay action at the same point in time of the playback of a content item (which rarely, if ever, would be the case in practical embodiments where there may be hundreds or thousands of UEs), then the first manifest file transmitted from, e.g., thefirst server206ato the UEs (as part ofblock212b) may need to effectively be adapted/modified in accordance with the specific circumstances/conditions associated with the playback by a respective UE. Referring back toFIG. 2B, such an adaptation/modification of the first manifest file is described in further detail below in respect of theUE202aofFIG. 2A. One skilled in the art will appreciate that other UEs (e.g., theUE218aofFIG. 2A) may perform a similar/analogous adaptation/modification.
• Inblock216b, theUE202amay obtain (e.g., receive) a command to initiate a trickplay action (e.g., a rewind, a pause, a resume, or a fast-forward). The trickplay command may be based on a user input obtained by theUE202a. As shown inFIG. 2B, block216bis denoted with a dashed outline which represents that a trickplay command might not be obtained in some instances. For reasons that will become clearer below, in some instances a generation of a second manifest file (as described below in conjunction withblock220b, as well as in conjunction withFIG. 2D) may be conditioned on obtaining a trickplay command in the first instance.
• Inblock220b, theUE202amay generate and/or modify a second manifest file that is based on the first manifest file received inblock212b. For example, the second manifest file may incorporate at least some of the metadata of the first manifest file that is received inblock212b.
• Assuming that upon entry intoblock220bthat the second manifest file already exists, theUE202amay, or might not, overwrite some or all of the metadata that may have been previously present in the second manifest file with the metadata included in the first manifest file (ofblock212b). To demonstrate, if upon entry intoblock220bthe (user of the)UE202ahad initiated a trickplay action (e.g., a pause in the playback of the selected content item) as shown inblock216band as represented atpoint202cinFIG. 2C, then it might not be desirable to overwrite the metadata associated with a portion of the selected content item that is proximate to thepoint202c. For example, it may be desirable (e.g., necessary) to maintain such metadata in the second manifest file in order to facilitate a resumption of the playback starting with the point in time that is just after when the playback was paused, such that there is continuity in the presentation of the selected content item on/by theUE202a. In this respect, as part ofblock220btheUE202amay supplement existing metadata in the second manifest file by adding/appending the metadata included in the first manifest file to the second manifest file (without deleting/discarding/overwriting the existing metadata).
• In some instances, upon entry intoblock220bit may be desirable or even necessary to delete/remove and/or ignore at least some of the metadata that may be exchanged (e.g., transmitted or received) as part of thesystem200a. For example, if due to a constraint (e.g., a physical constraint, such as a small form-factor) theUE202ahas insufficient storage (e.g., memory) capacity to add/append the metadata of the first manifest file (received inblock212b) to the second manifest file as described above, at least some of the pre-existing metadata that may be present in the second manifest file may be deleted/discarded/overwritten to create room for the incoming metadata of the first manifest file.
• The selection of metadata to delete/remove or ignore may be based on one or more rules. For example, a first rule may provide for an elimination/deletion of the oldest metadata first (e.g. as part of a first-in-first-out [FIFO] approach). A second rule may be to examine other metadata that indicates portions of the selected content item that are deemed to be important or given a high priority relative to other portions; metadata associated with lesser/lowest priority portions may be deleted/removed first to make/preserve capacity for higher priority portions. As an example of this second rule, if the selected content item is a movie pertaining to a solving of a murder mystery, metadata associated with a portion of the movie that reveals the identity of the murderer may be retained in favor of metadata associated with a portion of the movie that deals with the murderer's upbringing in rural Montana. Other rules may be established and utilized for selecting metadata to maintain/preserve or selecting metadata to delete/remove/overwrite.
• The second manifest file may be stored by theUE202a. In some embodiments, the second manifest file may be stored at/by another device that may be accessed by theUE202a.
• In terms of the obtaining of the portion of the selected content item inblock250b, the portion that is obtained may be based on, or performed in accordance with, terms/conditions imposed in the second manifest file ofblock220b.
• As described above, in some embodiments the generation of a second manifest file may be conditioned on receiving a trickplay command/input in the first instance. For example, if the creation/generation of the second manifest file represents appreciable/substantial overhead, it may be desirable to only create the second manifest file if it is needed, such as for example in relation to trickplay playback/actions.FIG. 2D illustrates amethod200dwhereby the generation of the second manifest file is conditioned on an initiation of a trickplay command.
• Themethod200dis similar to themethod200bofFIG. 2B, where similarly numbered ‘d’ blocks, e.g., blocks204d,208d,212d, and254d, are counterparts to ‘b’ blocks204b,208b,212b, and254b, respectively. Accordingly, a complete re-description of the aforementioned ‘d’ blocks is omitted herein for the sake of brevity.
• Inblock218d, theUE202amay make determination as to whether a trickplay command has been obtained (e.g., received). If so (e.g., the “yes” path is taken fromblock218d), flow may proceed fromblock218dto block222d. Otherwise (e.g., the “no” path is taken fromblock218d), flow may proceed fromblock218dto block226d.
• Inblock222d, a second manifest file may be generated and/or modified. The operations ofblock222dmay incorporate some or all of the aspects ofblock220bdescribed above. Fromblock222d, flow may proceed to block230d.
• Inblock226d, the first manifest file (ofblock212d) may be treated/declared as a selected manifest file.
• Inblock230d, the second manifest file (ofblock222d) may be treated/declared as a selected manifest file.
• Inblock234d, a portion of the selected content item (ofblock208d) may be obtained per the terms/conditions of the selected manifest file (e.g., the selected manifest file ofblock226dor block230d). The operations ofblock234dmay incorporate some or all of the aspects ofblock250bdescribed above.
• The playback ofblock254dmay be based on the obtained portion ofblock234d.
• While for purposes of simplicity of explanation, the respective processes are shown and described as a series of blocks inFIG. 2B andFIG. 2D, it is to be understood and appreciated that the claimed subject matter is not limited by the order of the blocks, as some blocks may occur in different orders and/or concurrently with other blocks from what is depicted and described herein. Moreover, not all illustrated blocks may be required to implement the methods described herein. While themethods200band200dare illustrated separately for the sake of convenience, in some embodiments aspects of a first of the methods (e.g., themethod200b) may be combined with aspects of one or more other methods (e.g., themethod200d).
• Aspects of the disclosure may be used to promote efficiency in terms of resource utilization. For example, aspects of the disclosure may enable one or more servers (or other network elements or devices) to simply distribute a manifest file to facilitate a playback of a content item without regard as to any playback options (e.g., trickplay actions) that may be initiated by a communications device (e.g., a UE) in respect of such a playback. Responsibility for maintaining a manifest file to facilitate trickplay playback/actions may be delegated/allocated to the communications device (or another device).
• Aspects of the disclosure may be applied in connection with one or more distribution models. For example, aspects of the disclosure may be applied with respect to a broadcast distribution model, a multicast distribution model (e.g., dissemination of pay-per-view or other subscription-based assets), etc. Aspects of the disclosure may be applied in conjunction with a streaming, over-the-top (OTT) distribution model, where content may be delivered to a communications device via a network (e.g., an Internet) connection.
• Aspects of the disclosure may be used to facilitate various playback options, including trickplay playback, on a resource-constrained device. For example, resource constraints may include limitations with respect to storage (e.g., memory) resources that are available, network connection constraints (e.g., limitations on bandwidth), power limitations (e.g., limited battery levels), etc. In some embodiments, the playback options may facilitate playback by the device without making sacrifices in terms of the quality or data-richness during a presentation of a content item. Still further, quality/data-richness with respect to a playback of a content item may be maintained while also accommodating other types of items (e.g., one or more operating systems, programs, applications, etc.) on/by the device.
• Referring now toFIG. 3, a block diagram300 is shown illustrating an example, non-limiting embodiment of a virtualized communication network in accordance with various aspects described herein. In particular a virtualized communication network is presented that can be used to implement some or all of the subsystems and functions ofcommunication network100, the subsystems and functions ofsystem200a, andmethods200band200dpresented inFIGS. 1, 2A, 2B, and 2D. For example,virtualized communication network300 can facilitate in whole or in part receiving a first indication of a plurality of content items that are available via a network, responsive to the receiving of the first indication, transmitting a second indication of a selection of a content item included in the plurality of content items, responsive to the transmitting of the second indication, receiving a first manifest file that identifies a location on the network where at least a first portion of data associated with the content item may be obtained, responsive to the receiving of the first manifest file, declaring one of the first manifest file or a second manifest file as a selected manifest file, and obtaining the at least a first portion of data from the location on the network in accordance with the selected manifest file.Virtualized communication network300 can facilitate in whole or in part receiving a first manifest file from a first server that includes first metadata that identifies a second server where a first portion of data associated with a content item is stored, responsive to the receiving of the first manifest file, determining that a trickplay command is received by a processing system, responsive to the determining that the trickplay command is received, generating or modifying a second manifest file to incorporate the first metadata, and obtaining the first portion of the data associated with the content item from the second server in accordance with the second manifest file.Virtualized communication network300 can facilitate in whole or in part receiving a first manifest file from a server, wherein the first manifest file comprises first metadata for obtaining first data associated with a first portion of a first content item, receiving a trickplay command with respect to a playback of the first portion of the first content item, receiving a second manifest file from the server subsequent to the receiving of the first manifest file, wherein the second manifest file comprises second metadata for obtaining second data associated with a second portion of the first content item, third data associated with a third portion of a second content item, or a combination thereof, and responsive to the receiving of the trickplay command and the receiving of the second manifest file, appending the second metadata to a third manifest file.
• In particular, a cloud networking architecture is shown that leverages cloud technologies and supports rapid innovation and scalability via atransport layer350, a virtualizednetwork function cloud325 and/or one or more cloud computing environments375. 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 ofnetwork elements150,152,154,156, 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 element150 (shown inFIG. 1), such as an edge router can be implemented via aVNE330 composed of NFV software modules, merchant silicon, and associated controllers. The software can be written so that increasing workload consumes incremental resources from a common resource pool, and moreover so that it's elastic: so the resources are only consumed when needed. In a similar fashion, other network elements such as other routers, switches, edge caches, and middle-boxes are instantiated from the common resource pool. Such sharing of infrastructure across a broad set of uses makes planning and growing infrastructure easier to manage.
• In an embodiment, thetransport layer350 includes fiber, cable, wired and/or wireless transport elements, network elements and interfaces to providebroadband access110,wireless access120,voice access130,media access140 and/or access tocontent sources175 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 asVNEs330,332 or334. These network elements can be included intransport layer350.
• The virtualizednetwork function cloud325 interfaces with thetransport layer350 to provide theVNEs330,332,334, etc. to provide specific NFVs. In particular, the virtualizednetwork function cloud325 leverages cloud operations, applications, and architectures to support networking workloads. Thevirtualized network elements330,332 and334 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,VNEs330,332 and334 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. Thesevirtual network elements330,332,334, etc. can be instantiated and managed using an orchestration approach similar to those used in cloud compute services.
• The cloud computing environments375 can interface with the virtualizednetwork function cloud325 via APIs that expose functional capabilities of theVNEs330,332,334, etc. to provide the flexible and expanded capabilities to the virtualizednetwork function cloud325. In particular, network workloads may have applications distributed across the virtualizednetwork function cloud325 and cloud computing environment375 and in the commercial cloud, or might simply orchestrate workloads supported entirely in NFV infrastructure from these third party locations.

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.
• Turning now toFIG. 5, an embodiment500 of amobile network platform510 is shown that is an example ofnetwork elements150,152,154,156, and/orVNEs330,332,334, etc. For example,platform510 can facilitate in whole or in part receiving a first indication of a plurality of content items that are available via a network, responsive to the receiving of the first indication, transmitting a second indication of a selection of a content item included in the plurality of content items, responsive to the transmitting of the second indication, receiving a first manifest file that identifies a location on the network where at least a first portion of data associated with the content item may be obtained, responsive to the receiving of the first manifest file, declaring one of the first manifest file or a second manifest file as a selected manifest file, and obtaining the at least a first portion of data from the location on the network in accordance with the selected manifest file.Platform510 can facilitate in whole or in part receiving a first manifest file from a first server that includes first metadata that identifies a second server where a first portion of data associated with a content item is stored, responsive to the receiving of the first manifest file, determining that a trickplay command is received by a processing system, responsive to the determining that the trickplay command is received, generating or modifying a second manifest file to incorporate the first metadata, and obtaining the first portion of the data associated with the content item from the second server in accordance with the second manifest file.Platform510 can facilitate in whole or in part receiving a first manifest file from a server, wherein the first manifest file comprises first metadata for obtaining first data associated with a first portion of a first content item, receiving a trickplay command with respect to a playback of the first portion of the first content item, receiving a second manifest file from the server subsequent to the receiving of the first manifest file, wherein the second manifest file comprises second metadata for obtaining second data associated with a second portion of the first content item, third data associated with a third portion of a second content item, or a combination thereof, and responsive to the receiving of the trickplay command and the receiving of the second manifest file, appending the second metadata to a third manifest file.
• In one or more embodiments, themobile network platform510 can generate and receive signals transmitted and received by base stations or access points such as base station oraccess point122. Generally,mobile network platform510 can comprise components, e.g., nodes, gateways, interfaces, servers, or disparate platforms, that facilitate both packet-switched (PS) (e.g., internet protocol (IP), frame relay, asynchronous transfer mode (ATM)) and circuit-switched (CS) traffic (e.g., voice and data), as well as control generation for networked wireless telecommunication. As a non-limiting example,mobile network platform510 can be included in telecommunications carrier networks, and can be considered carrier-side components as discussed elsewhere herein.Mobile network platform510 comprises CS gateway node(s)512 which can interface CS traffic received from legacy networks like telephony network(s)540 (e.g., public switched telephone network (PSTN), or public land mobile network (PLMN)) or a signaling system #7 (SS7)network560. CS gateway node(s)512 can authorize and authenticate traffic (e.g., voice) arising from such networks. Additionally, CS gateway node(s)512 can access mobility, or roaming, data generated throughSS7 network560; for instance, mobility data stored in a visited location register (VLR), which can reside inmemory530. Moreover, CS gateway node(s)512 interfaces CS-based traffic and signaling and PS gateway node(s)518. As an example, in a 3GPP UMTS network, CS gateway node(s)512 can be realized at least in part in gateway GPRS support node(s) (GGSN). It should be appreciated that functionality and specific operation of CS gateway node(s)512, PS gateway node(s)518, and serving node(s)516, is provided and dictated by radio technology(ies) utilized bymobile network platform510 for telecommunication over aradio access network520 with other devices, such as aradiotelephone575.
• In addition to receiving and processing CS-switched traffic and signaling, PS gateway node(s)518 can authorize and authenticate PS-based data sessions with served mobile devices. Data sessions can comprise traffic, or content(s), exchanged with networks external to themobile network platform510, like wide area network(s) (WANs)550, enterprise network(s)570, and service network(s)580, which can be embodied in local area network(s) (LANs), can also be interfaced withmobile network platform510 through PS gateway node(s)518. It is to be noted thatWANs550 and enterprise network(s)570 can embody, at least in part, a service network(s) like IP multimedia subsystem (IMS). Based on radio technology layer(s) available in technology resource(s) orradio access network520, PS gateway node(s)518 can generate packet data protocol contexts when a data session is established; other data structures that facilitate routing of packetized data also can be generated. To that end, in an aspect, PS gateway node(s)518 can comprise a tunnel interface (e.g., tunnel termination gateway (TTG) in 3GPP UMTS network(s) (not shown)) which can facilitate packetized communication with disparate wireless network(s), such as Wi-Fi networks.
• In embodiment500,mobile network platform510 also comprises serving node(s)516 that, based upon available radio technology layer(s) within technology resource(s) in theradio access network520, convey the various packetized flows of data streams received through PS gateway node(s)518. It is to be noted that for technology resource(s) that rely primarily on CS communication, server node(s) can deliver traffic without reliance on PS gateway node(s)518; for example, server node(s) can embody at least in part a mobile switching center. As an example, in a 3GPP UMTS network, serving node(s)516 can be embodied in serving GPRS support node(s) (SGSN).
• For radio technologies that exploit packetized communication, server(s)514 inmobile network platform510 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 bymobile network platform510. 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 throughmobile network platform510 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,WAN550 or Global Positioning System (GPS) network(s) (not shown). Provisioning server(s) can also provision coverage through networks associated to mobile network platform510 (e.g., deployed and operated by the same service provider), such as the distributed antennas networks shown inFIG. 1(s) 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 ofmobile network platform510. To that end, the one or more processor can execute code instructions stored inmemory530, 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 embodiment500,memory530 can store information related to operation ofmobile network platform510. Other operational information can comprise provisioning information of mobile devices served throughmobile network platform510, subscriber databases; application intelligence, pricing schemes, e.g., promotional rates, flat-rate programs, couponing campaigns; technical specification(s) consistent with telecommunication protocols for operation of disparate radio, or wireless, technology layers; and so forth.Memory530 can also store information from at least one of telephony network(s)540,WAN550,SS7 network560, or enterprise network(s)570. In an aspect,memory530 can be, for example, accessed as part of a data store component or as a remotely connected memory store.

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.
• In one or more embodiments, information regarding use of services can be generated including services being accessed, media consumption history, user preferences, and so forth. This information can be obtained by various methods including user input, detecting types of communications (e.g., video content vs. audio content), analysis of content streams, sampling, and so forth. The generating, obtaining and/or monitoring of this information can be responsive to an authorization provided by the user. In one or more embodiments, an analysis of data can be subject to authorization from user(s) associated with the data, such as an opt-in, an opt-out, acknowledgement requirements, notifications, selective authorization based on types of data, and so forth.
• 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.
