## Title
Method, apparatus, network entity, system and computer program product for sharing content

## Abstract

A method, apparatus, network entity, system and computer program product are provided for content sharing. In particular, a technique is provided whereby an individual desiring to share content including, for example, photograph albums, music or video files, or the like, need only select the individual(s) with whom he or she would like to share the content, and the device on which he or she is operating will determine all of the necessary protocols, connectivity bearers, and the like, for sharing the content, as well as the appropriate device with which the content should be shared.

## Background
FIELD
Exemplary embodiments of the present invention relate, generally, to sharing content and, in particular, to a technique for seamlessly sharing content in a manner that is transparent to the user.
BACKGROUND
With the usage of advanced features in the latest personal devices (e.g., cellular telephones, personal digital assistants (PDAs) pagers, and the like) the creation and consumption of digital content has become part of many individuals' everyday life. This includes taking digital photos, listening to digital music, watching short videos, and more. Apart from self-creation and self-consumption, the concept of content sharing is stronger than ever. People want to be able to share their content on many different levels with others including, for example, their family, friends and colleagues.
One problem arises, however, from the fact that there are many different protocols or services that can be used for exchanging content, and each protocol or service may be ideal for certain situations, but not for others. Examples of such services include E-mail, which is mostly used for person-to-person communication, is targeted to devices connected to the Internet, and requires certain infrastructure (e.g., E-mail servers, etc.); Multimedia Messaging Service (MMS), which is used in the mobile domain and is targeted for exchanging small media files; and Universal Plug and Play (UPnP)/Audio Video (AV), which is targeted to device-to-device communications and, while it supports large files, is targeted mainly for personal devices, wherein the sending and receiving devices are typically owned by the same person.
Other examples of services or protocols used for exchanging content include Atom, an XML-based syndication format that is mainly used for uploading content to weblogs; Web Distributed Authoring and Versioning (WebDAV), which is an enhancement to the HTTP protocol that enables documents to be written via HTTP, is mainly used in the enterprise domain, supports large files, and requires numerous settings; Peer-to-Peer networks, which are used for public user-to-user exchange of large files; and Bluetooth Object Exchange (OBEX), which is targeted to device-to-device content exchange where devices are in proximity of one another.
Because the majority of devices, both fixed and mobile, support many of these services and protocols, it is up to the user desiring to transmit or share his or her content with other individuals to select the appropriate one for each particular instance (i.e., depending upon, for example, what content he or she is transmitting and/or where, in relation to his or her device, the intended recipient is located).
In addition to the numerous available services and protocols, there are also numerous connectivity bearers that may be used, wherein, like the services and protocols, each may be best for a specific instance. Examples of such connectivity bearers include Cellular Packet Radio, used for mobile devices; Wireless Local Area Network (WLAN) Infrastructure, used both in fixed and mobile devices typically for Internet connectivity; WLAN Ad-hoc, which is used primarily in mobile devices for proximity services (e.g., mobile-to-mobile connectivity); Bluetooth, which, like WLAN Ad-hoc, is typically used in mobile devices for proximity services; and the fixed Internet, which is used by static devices for Internet connectivity.
A user may, likewise, be required to determine and specify which connectivity bearer should be used depending upon, among other things, the content he or she is sharing and, as above, where his or her device is located with respect to the intended recipient.
To make things even more complicated, many individuals have more than one device (e.g., a cellular telephone, PDA, pager, home media center or content server, personal computer (PC), laptop, etc.), wherein each device may have a different range of connectivity (e.g., short or wide) and different capabilities for handing different types and sizes of content. For example, while a PC may support E-mail, UPnP/AV, Peer-to-Peer, and the like, an individual's cellular telephone may support Bluetooth, MMS and E-mail.
In order to share content, a user may be required to determine, among other things, which service or protocol to use, which connectivity bearer to use, and to which device associated with an intended recipient to transmit the content. In order to make these determinations, the user may be required to determine, for example, whether the sending and the receiving devices support the same protocols, whether the receiving device is in proximity and, if not, whether it can be reached using an alternative method, whether the receiving device can handle (render) the specific content type or the size of the shared file (i.e., does the receiving device have the requisite memory space), or how will the sending and receiving devices exchange settings (e.g., MAC/IP addresses, usernames, passwords, security keys, directory paths, etc.).
In addition to the foregoing, in many instances users are able to invite other individuals to remotely access content stored on the user's home PC or server, or even his or her mobile device. While beneficial, this too may cause even further issues in terms of how the invitees will know how or where to access the content, particularly if the user moves the content from one device (e.g., his or her mobile device) to another (e.g., his or her media server).
A need, therefore, exists for an easier way to share content with others that does not require a user to make difficult determinations in terms of how and to where to transmit the content.
BRIEF SUMMARY
In general, exemplary embodiments of the present invention provide an improvement over the known prior art by, among other things, refocusing existing device-centric content sharing to a more people-centric method of sharing content. In particular, exemplary embodiments enable an individual to merely select to whom they would like to share the content, and the individual's device, rather than the individual himself, will make the aforementioned decisions regarding how and to where to send the content and/or from where and how to access the content. The determinations may be based, for example, on the type and/or size of the content being shared, the capabilities of various devices associated with the intended recipient or sharing party (i.e., a party offering various content files for the user to access) and/or the proximity of the intended recipient's/sharing party's devices, to name a few. In order to make these decisions, the electronic device of one exemplary embodiment accesses a personal resource file or database associated with the intended recipient or sharing party that provides information regarding each of the intended recipient's/sharing party's devices.
In accordance with one aspect, a method is provided of sharing content. In one exemplary embodiment, the method includes: (1) accessing a resource file associated with a party, wherein the resource file comprises information relating to one or more devices associated with the party; and (2) determining a manner in which to share one or more content files with the party based at least in part on the information included in the resource file.
According to yet another aspect, a network entity is provided for sharing content. In one exemplary embodiment, the network entity includes a processor and a memory in communication with the processor. The memory of this exemplary embodiment stores one or more resource files corresponding with a respective one or more parties, wherein respective resource files comprise information relating to one or more devices associated with the respective parties, and wherein respective resource files are capable of being used to determine a manner in which to share one or more content files with the respective parties. The memory may further store an application executable by the processor, wherein the application is configured, upon execution, to provide access to the resource files.
According to another aspect, an apparatus is provided that is capable of sharing content. In one exemplary embodiment the mobile device includes a processor and a memory in communication with the processor that stores an application executable by the processor, wherein the application is configured, upon execution, to: (1) access a resource file associated with a party, wherein the resource file comprises information relating to one or more devices associated with the party; and (2) determine a manner in which to share one or more content files with the party based at least in part on the information included in the resource file.
In accordance with yet another aspect, a computer program product is provided for sharing content. The computer program product contains at least one computer-readable storage medium having computer-readable program code portions stored therein. The computer-readable program code portions of one exemplary embodiment include: (1) a first executable portion for accessing a resource file associated with a party, wherein the resource file comprises information relating to one or more devices associated with the party; and (2) a second executable portion for determining a manner in which to share one or more content files with the party based at least in part on the information included in the resource file.
In accordance with another aspect, a system for content sharing is provided. In one exemplary embodiment, the system includes a database comprising one or more resource files corresponding with a respective one or more parties, and an apparatus configured to access at least one of the resource files. Respective resource files of this exemplary embodiment include information relating to one or more devices associated with the respective parties, and the apparatus is configured to determine, based at least in part on this information, a manner in which to share one or more content files with the party corresponding with the accessed resource file.

DETAILED DESCRIPTION
Exemplary embodiments of the present invention now will be described more fully hereinafter with reference to the accompanying drawings, in which some, but not all embodiments of the inventions are shown. Indeed, exemplary embodiments of the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. Like numbers refer to like elements throughout.
Overview
In general, exemplary embodiments of the present invention involve the generation of personal resource files or databases that are associated with respective individuals and include information relating to, for example, the protocols, capabilities, addresses, bearers and security associations relating to each of the individual's personal devices (e.g., his or her cellular telephone, PDA, pager, PC, laptop, home media server, etc.). When another individual (referred to herein as the “sender”) wishes to share content, such as digital photographs, music files, or the like, with the individual with whom the resource file is associated (referred to herein as the “intended recipient”), the sender need only select the contact entry associated with the intended recipient in the sender's device contact list (e.g., an address or phone book application operating on the electronic device), and the device will access the resource file associated with the intended recipient and determine, based, for example, on the type and size of the content to be shared, the proximity and availability of the intended recipient's device, and the like, what service or protocol and connectivity bearer to use, as well as to which of the intended recipient's devices to send the content.
In addition, exemplary embodiments of the present invention may be used to facilitate the offering of content to others. As used herein “offering” refers to the instance where an individual (referred to herein as the “sharing party”) invites other individuals (referred to as the “visitors”) to access content, such as photo albums or the like, stored on various devices associated with the sharing party. In this exemplary embodiment, the personal resource file associated with the sharing party may include a list of albums the sharing party desires to offer along with links to the devices on which respective albums are stored and information relating to the supported protocols, configurations, and the like of those devices. When a visitor wishes to access content made accessible by the sharing party, the visitor's device retrieves the resource file associated with the sharing party and uses it to determine how best to gain access to the content.
As is discussed in more detail below, the personal resource files may be stored on a server that is publicly accessible via a Wide Area Network (WAN) (e.g., the Internet). In this exemplary embodiment, the sender or visitor devices may browse to an address (e.g., a URL address) provided by the intended recipient or sharing party in order to access the corresponding resource file. Alternatively, the resource files may be maintained by a Presence Server, wherein the information contained in the resource files may be provided to mobile devices as part of the Presence Service provided by the mobile device operator. In yet another exemplary embodiment, the resource files may be stored directly on the sender/visitor devices themselves. In this latter embodiment, the device may periodically synchronize the resource files stored on the device with, for example, those stored on a central server or with a peer-to-peer device.
Method of Seamlessly Sharing Content
Reference is now made to FIG. 1, which illustrates the steps which may be taken in order to alleviate the burden placed on individuals seeking to share content with and/or offer content to others. As shown the process begins at Step 101, wherein a personal resource file or database is created for a particular individual or party. As discussed above, the resource file includes information, such as the protocols and connectivity bearers supported by, the capabilities of, and/or the security associations relating to respective devices operated by, or otherwise associated with, the individual. In particular, each device, for which information is included in the personal resource file, supports content sharing via one or more content transfer protocols (e.g., UPnP, WebDAV, Atom, etc.). The devices further have one or more connectivity interfaces (e.g., WLAN, Bluetooth, General Packet Radio Service (GPRS), etc.), and the device services are addressable using one or more Internet/proximity addresses (e.g., URLs, MAC addresses, etc.). The personal resource file includes a description of some portion, if not all, of the foregoing.
The following provides an example of the information which may be included in a personal resource file of an individual having a cellular telephone, a PC, a media server and a weblog, all of which support content sharing:

As will be recognized by those of ordinary skill in the art, any format may be used for the resource file including, for example, Extended Markup Language (XML), Really Simple Syndication (RSS), or the like. In one exemplary embodiment, once the resource file has been created, the devices themselves are responsible for providing the information stored therein. To illustrate, FIG. 2 represents an individual's cellular telephone 10, PC 50, and media server 60 communicating with a host server 22, on which the individual's corresponding resource file 70 is stored, for the purpose of providing information related to the respective devices.
In addition to the foregoing, Step 101 may further include providing a list within the personal resource file of one or more content files that are stored on respective devices associated with the individual, and which may be accessed by certain other individuals (i.e., content files being offered to visitors). The resource file may further include information regarding how best to access those content files (e.g., an address where they can be located, a method, protocol and/or configuration to use when doing so, etc.). According to exemplary embodiments, therefore, individuals can avoid uploading content files, such as photo albums, music files, and the like, to publicly available web sites and can, instead, just provide information regarding how to access the content directly on their devices. To illustrate, the following provides an exemplary resource file including information regarding two photo albums (BestOfShopping and Summer2005) being offered:

As shown, in addition to specifying the available content files and their location, the resource file may specify which third parties (i.e., visitors) have access rights to the stored content files, discussed in detail below.
In one exemplary embodiment, where information associated with a particular device changes (e.g., the capabilities of an individual's cellular telephone improve because of additional services purchased by the individual), the device may automatically update the resource file. In particular, the device may access the resource file (in a manner described below with reference to Step 104), and modify the information included, such that the resource file will maintain up-to-date information regarding each of the individual's devices. Respective devices may further update the resource file when a particular content file is moved from one device to another, or when the content file has been updated (e.g., new photographs have been added to the album). To illustrate, FIG. 3 represents the situation where an individual has moved the content file for the photo album BestOfShopping 80 from his or her cellular telephone 10 to his or her media server 60. As shown, in one exemplary embodiment, the cellular telephone 10 will update the individual's resource file 70 by deleting or removing the reference to the photo album that has been removed from the phone 72 from its portion of the resource file 70. In addition, the media server 60 of this exemplary embodiment will update the resource file 70 by adding the removed reference 72 to its section of the resource file 70. According to this embodiment, visitors need not be individually informed when and to where content files, to which they have been granted access, have been moved.
Returning to FIG. 1, the process continues, in Step 102, where an individual (e.g., a sender) selects one or more content files, for example, saved on his or her device, for the purpose of transmitting the file(s) to an intended recipient. As discussed above, the content files may include, for example, digital photographs, music files, video clips, and the like. As will be recognized by those of ordinary skill in the art, in the instance where the individual desires to access (rather than transmit) content stored on a device associated with a sharing party, Step 102 may be bypassed and the process continues directly to Step 103.
Once the content file(s) have been selected (or once the resource file has been created, in the instance where the individual associated with the resource file has offered content for sharing), the sender/visitor may then select a contact from his or her address or phone book to which to transmit the selected content file(s) or whose content he or she would like to access. (Step 103).
In one exemplary embodiment, this may involve highlighting and selecting the name, phone number, or E-mail address of the contact as displayed on a display screen of the electronic device. Alternatively, where, for example, the electronic device responds to voice commands, Step 103 may involve speaking the name of the contact or some other word or phrase associated therewith (e.g., “mom,” “secretary,” etc.).
At this point, the device on which the sender is operating will access the resource file associated with the contact selected. (Step 104). In one exemplary embodiment, the personal resource files or databases associated with various individuals may be stored on a server that is publicly accessible via, for example, a WAN (e.g., the Internet). In this exemplary embodiment, respective contact entries of an individual's content list may include the address (e.g., a URL address) of the corresponding personal resource file (e.g., http://www.isp.com/my_resource.xml). When the sender selects the contact entry, the device may browse to the address included in the contact entry in order to access the resource file. In this exemplary embodiment, in order for individual devices, for which information is included in respective personal resource files, to periodically update that information, as discussed above, the devices will simply browse to the address and update the information stored at that location.
In another exemplary embodiment, a cellular network operator's Presence Service may be used to store and provide access to the various personal resource files. As will be recognized by those of ordinary skill in the art, Presence refers to the ability and willingness of a user to communicate information regarding the location and availability of his or her device(s) across various sets of services and devices. Presence information is typically linked to the device's telephone number and is published, in the form of a Presence Document, to other devices having the corresponding telephone number stored thereon (e.g., in the form of a contact entry relating to the user). When an individual accesses his or her contact list, he or she can view the Presence Document in order to see whether the corresponding contact is available or, for example, in a meeting. Presence enablers are currently installed by many cellular operators in order to provide their customers services such as, Instant Messaging (IMing), push-to-talk, and the like.
According to this exemplary embodiment, the existing Presence Service offered by cellular network operators may be used to provide a “sharing service.” In particular, the Presence Documents used to publish the Presence information relating to a particular individual or device may include the personal resource file associated with that individual. In other words, in addition to using the Presence Service to advertise presence information, an individual can use the service to also advertise protocol, bearer, capability and security information relating to his or her devices, as well as information regarding various content files that are being offered to third parties.
The following information may be included in the Presence Document according to exemplary embodiments of the present invention: Sharing Service availability, indicating a user's willingness to communicate using this service (e.g., “open” may indicate that the user is willing to be contacted, while “closed” may indicate that the user is not willing to communicate using the sharing service); a Sharing Service Identifier, which is published to indicate the type of service described by the tuple; a list of devices in which the Sharing Service is running (e.g., a list of hardware devices capable of running the service), whereby content may be delivered according to the content type, device capabilities and priorities of the devices running the Sharing Service; and the information discussed above relating to the individual devices (e.g., protocols, bearers, capabilities, etc.).
The following Presence Document illustrates an example of a Sharing Service running on four devices, namely a mobile phone, a home server, a public media server, and a weblog server. The mobile phone of this example is capable of receiving content over Bluetooth, MMS and WLAN. Content may be sent to the home server via UPnp technology. The media server may be exposing a UPnP and a WebDAV interface, and the weblog server may be accessed over HTTP.

One advantage of this embodiment over the former (i.e., storing the resource files on a server publicly available via the Internet) is that there is no need for the contact entry to include an address associated with the resource file (i.e., there is no need for the individual associated with either the contact entry or the device to manually enter the address). In contrast, the resource file will be directly linked to the telephone number in the contact entry. When a user selects the contact, the network operator will use the telephone number to find the presence information, or Presence Document, (including the resource file) stored on the Presence Server and then provide that information to the user's device.
One disadvantage to this embodiment, however, is that because Presence Service is a service offered by cellular network operators, it is limited to use within the mobile or cellular domain. An alternative embodiment, therefore, provides a hybrid of the preceding two embodiments. In particular, according to one exemplary embodiment, the personal resource file or database may be maintained on a publicly available server (as was the case in the first embodiment described above), and the link to the resource file, rather than the file itself, may be published using the Presence Service. In other words, the Presence Document, which is linked to the individual's telephone number, will contain the address associated with the resource file, rather than the resource file itself. Electronic devices will be able to access the resource file by either browsing to the address contained in a particular contact entry (i.e., where the device is not associated with a cellular network operator), or accessing the Presence Document associated with the telephone number of the particular contact, retrieving the address, and then accessing the resource file using the address (i.e., where the device is associated with a cellular network operator).
The following illustrates how a Sharing Service may publish a link to the resource file or database in a Presence Document:

In yet another exemplary embodiment, the resource files may be stored directly on the electronic device itself. The disadvantages to this embodiment, however, are that the various resource files may take up a considerable amount of the device memory, and it may be difficult for various devices, for which information is provided in the resource files, to update that information in the event of changes to their capabilities, supported protocols and/or bearers, or the like. In one exemplary embodiment, the latter disadvantage may be lessened, however, by enabling the device to periodically synchronize the resource files stored thereon with, for example, those stored on a central server (i.e., enabling various updates to be performed to the files while saved on the server rather than directly on the device) or with a peer-to-peer device.
Regardless of where the resource file is located or how it is accessed, the process continues, in Step 105, when the sender/visitor device determines the manner in which to share content with the selected contact or party. The determination may be based, at least in part, on the information included in the resource file, as well as the type and/or size of the content file(s) either selected in Step 102 or described in the accessed resource file (in the instance where the party seeks to access, rather than transmit, the content file). Determining the manner in which to share the selected content may include, for example, determining which protocol and/or connectivity bearer to use, as well as to which of the intended recipient's devices to transmit the selected content. Where the object is to access one or more content files being offered by the contact, Step 105 may include determining on which device the content is available, and what protocol, connectivity bearer and/or address to use in order to access the content file(s).
Once the manner has been selected, the device, in Step 106, shares the content with the selected contact in the manner determined in Step 105. This may include, for example, transferring the selected content to one of the devices associated with the contact, or accessing one or more content files available on the contact's device(s).
To illustrate, in one exemplary embodiment where a sender has selected the contact entry corresponding with an intended recipient having a resource file that resembles that illustrated above, once the device has retrieved the resource file, the device will first check to see whether the intended recipient is in proximity. In other words, it will check to see whether Bluetooth or WLAN Ad-hoc may be used to transmit the selected content to the intended recipient. Where the intended recipient is in proximity, the device establishes a connection with either the Bluetooth address provided in the resource file (11:22:33:44:55:66) or the WLAN address (77:88:99:00:11:22), and then uses defined higher transfer protocols to send the content. If the intended recipient is not in proximity, the device will attempt to use an alternative sharing method as described in the resource file. For example, the device may connect via remote access to the intended recipient's home computer (e.g., by accessing the UPnP server at http://mypc.isp.com:5678/UPnP)
According to one exemplary embodiment of the present invention if, while the sender/visitor is in the process of transmitting/accessing the content files, a change occurs with respect to the intended recipient/sharing party and/or his or her device(s), the device on which the sender/visitor is operating will recognize this change and proceed accordingly. For example, consider the scenario where the sharing party was originally in proximity of the visitor, causing the visitor to use Bluetooth or WLAN Ad-hoc, for example, to access the shared content files, but then moves out of proximity while the visitor is still accessing the shared content file. In this instance, the visitor device will see that the Bluetooth or WLAN Ad-hoc connection has been lost, but that the resource file indicates that the content is also accessible remotely via, for example HTTP, and will establish a connection via remote access. In one exemplary embodiment, this entire process may be transparent to the visitor.
As noted above, according to exemplary embodiments of the present invention, a sharing party may be able to specify, within his or her resource file, specific parties having access to specific content files. Where, for example, a party without access to a particular content file retrieves the sharing party's resource file, reference to that particular content file (e.g., where it is located and how it can be accessed) may not be included in the resource file retrieved. In this exemplary embodiment, the server hosting the resource file (e.g., the publicly accessible server, or the presence server), may be responsible for filtering the resource file prior to providing it to parties requesting it. In addition, parties may be required to authenticate themselves using, for example, a username and a password, prior to receiving the requested resource file.
Resource files stored on a publicly available server may further be encrypted, such that only parties having the correct decryption keys would be able to access the data. In one exemplary embodiment, the sharing party may distribute the keys to his or her friends and family using, for example, a Short Message Service (SMS) or MMS message, or E-mail. As will be recognized by those of ordinary skill in the art, any number of methods or means may be used to secure the data included in personal resource files so that parties who are not authorized to access the data are unable to do so, without departing from the spirit and scope of exemplary embodiments of the present invention.
Exemplary embodiments of the present invention provide several advantages over the prior art by, among other things, greatly reducing the burden placed on individuals seeking to share content with other individuals. In particular, according to exemplary embodiments, content sharing can be performed by simply selecting a person with whom to share the content. All of the technical issues (e.g., device/service discovery, connection establishment, data transfer, protocols to be used, etc.) are handled by the system without the user's direct involvement. Similarly, the offering of content is done transparently, such that visitors access photo albums, and the like, without knowing where they are located or how they are being accessed. Even if a connection is lost, another connection may be seamlessly created. Even where content files are moved, they can easily be accessed, without the visitor even being cognizant of the move.
Overall System and Mobile Device
Referring to FIG. 4, an illustration of one type of system that would benefit from exemplary embodiments of the present invention is provided. As shown in FIG. 4, the system can include one or more mobile stations 10, each having an antenna 12 for transmitting signals to and for receiving signals from one or more base stations (BS's) 14. The base station is a part of one or more cellular or mobile networks that each includes elements required to operate the network, such as one or more mobile switching centers (MSC) 16. As well known to those skilled in the art, the mobile network may also be referred to as a Base Station/MSC/Interworking function (BMI). In operation, the MSC is capable of routing calls, data or the like to and from mobile stations when those mobile stations are making and receiving calls, data or the like. The MSC can also provide a connection to landline trunks when mobile stations are involved in a call.
The MSC 16 can be coupled to a data network, such as a local area network (LAN), a metropolitan area network (MAN), and/or a wide area network (WAN). The MSC can be directly coupled to the data network. In one typical embodiment, however, the MSC is coupled to a Packet Control Function (PCF) 18, and the PCF is coupled to a Packet Data Serving Node (PDSN) 19, which is in turn coupled to a WAN, such as the Internet 20. In turn, devices such as processing elements (e.g., personal computers, server computers or the like) can be coupled to the mobile station 10 via the Internet. For example, the processing elements may include a Host Server 22 and/or a Presence Server 24, configured to store one or more personal resource files and from which the resource files may be accessed in accordance with Step 104 of FIG. 1, discussed above. As will be appreciated, the processing elements can comprise any of a number of processing devices, systems or the like capable of operating in accordance with embodiments of the present invention.
The BS 14 can also be coupled to a signaling GPRS (General Packet Radio Service) support node (SGSN) 30. As known to those skilled in the art, the SGSN is typically capable of performing functions similar to the MSC 16 for packet switched services. The SGSN, like the MSC, can be coupled to a data network, such as the Internet 20. The SGSN can be directly coupled to the data network. In a more typical embodiment, however, the SGSN is coupled to a packet-switched core network, such as a GPRS core network 32. The packet-switched core network is then coupled to another GTW, such as a GTW GPRS support node (GGSN) 34, and the GGSN is coupled to the Internet.
Although not every element of every possible network is shown and described herein, it should be appreciated that the mobile station 10 may be coupled to one or more of any of a number of different networks. In this regard, mobile network(s) can be capable of supporting communication in accordance with any one or more of a number of first-generation (1G), second-generation (2G), 2.5G and/or third-generation (3G) mobile communication protocols or the like. More particularly, one or more mobile stations may be coupled to one or more networks capable of supporting communication in accordance with 2G wireless communication protocols IS-136 (TDMA), GSM, and IS-95 (CDMA). Also, for example, one or more of the network(s) can be capable of supporting communication in accordance with 2.5G wireless communication protocols GPRS, Enhanced Data GSM Environment (EDGE), or the like. In addition, for example, one or more of the network(s) can be capable of supporting communication in accordance with 3G wireless communication protocols such as Universal Mobile Telephone System (UMTS) network employing Wideband Code Division Multiple Access (WCDMA) radio access technology. Some narrow-band AMPS (NAMPS), as well as TACS, network(s) may also benefit from embodiments of the present invention, as should dual or higher mode mobile stations (e.g., digital/analog or TDMA/CDMA/analog phones).
One or more mobile stations 10 (as well as one or more processing elements, although not shown as such in FIG. 4) can further be coupled to one or more wireless access points (APs) 36. The AP's can be configured to communicate with the mobile station in accordance with techniques such as, for example, radio frequency (RF), Bluetooth (BT), infrared (IrDA) or any of a number of different wireless networking techniques, including WLAN techniques. The APs may be coupled to the Internet 20. Like with the MSC 16, the AP's can be directly coupled to the Internet. In one embodiment, however, the APs are indirectly coupled to the Internet via a GTW 28. As will be appreciated, by directly or indirectly connecting the mobile stations and the processing elements (e.g., Host Server 22 and/or Presence Server 24) and/or any of a number of other devices to the Internet, whether via the AP's or the mobile network(s), the mobile stations and processing elements can communicate with one another to thereby carry out various functions of the respective entities, such as to transmit and/or receive data, content or the like. As used herein, the terms “data,” “content,” “information,” and similar terms may be used interchangeably to refer to data capable of being transmitted, received and/or stored in accordance with embodiments of the present invention. Thus, use of any such terms should not be taken to limit the spirit and scope of the present invention.
Although not shown in FIG. 4, in addition to or in lieu of coupling the mobile stations 10 to one or more processing elements (e.g., the Host Server 22 and/or Presence Server 24) across the Internet 20, one or more such entities may be directly coupled to one another. As such, one or more network entities may communicate with one another in accordance with, for example, RF, BT, IrDA or any of a number of different wireline or wireless communication techniques, including LAN and/or WLAN techniques. Further, the mobile station 10 and the processing elements can be coupled to one or more electronic devices, such as printers, digital projectors and/or other multimedia capturing, producing and/or storing devices (e.g., other terminals).
