  • SIP Session Initiation Protocol
  • a mobile handset When a mobile handset first powers on, logic residing in the handset initiates a "registration" procedure with the IMS core, first by requesting the radio access network to assign it an IP address. After it receives an IP address, the mobile handset attempts to register as an IP-enabled endpoint with the IMS core, by sending a "register" request to the P-CSCF. Assuming that the handset is registering from a visiting domain, the P-CSCF then uses a Domain Name Server (DNS) to search for the handset's home domain S-CSCF. Once the P-CSCF locates the S-CSCF for the mobile handset, it passes the "register" request to that S-CSCF.
  • DNS Domain Name Server
  • the S-CSCF contacts the Home Subscriber Subsystem (HSS), which looks up the mobile handset's profile. This profile contains assorted information about the user, and what services the handset is authorized to use. A logical function in the S-CSCF called the "registrar” then authenticates the mobile handset, e.g., verifies that the handset is legitimate. [0009]

  • embodiments of the invention allow a multimedia object to be rendered, i.e., displayed and played on the audio/video outputs of the receiving party handset, without allowing the receiving party to store, copy or preserve for later use the object itself. It is assumed that the party, i.e., first party, initiating the rendering of the multimedia object has the right to render the object in question for personal use. The present application assumes that rendering such an object for a second party, without allowing said party to store, copy or preserve for later use, does not violate any rights.
  • Combinational services are gaining popularity amongst wireless operators worldwide and several such operators have expressed interest in offering such services to their subscribers. It has been estimated that 900 million handsets will be capable of receiving simultaneous CS and PS connections by the year 2011 , i.e., will be capable of supporting combinational services. More than 50% of handsets manufactured today contain cameras and other appurtenances for supporting the rendering of multimedia objects. As has been stated before a combinational service, as envisioned by 3GPP, uses the CS connection for carrying voice and uses the PS connection for carrying the multimedia objects, simultaneously. Often cited examples of combinational services are as follows:
  • IP signaling in mobile devices we begin by describing IP signaling in mobile devices and how IP connectivity can be re-established if handset becomes not IP-accessible. We then describe how a CS network can be used to initiate connection to the PS network using a service delivery platform (SDP). We then focus our attention on the Serving Node (SN) and the personal agent (PA) components of the SDP. Finally, we describe the details of the system and methods for preserving digital rights and personal content in combinational services. IP Signaling in Mobile Devices
  • a network operator may disconnect a mobile handset from a packet-switched (PS) network by withdrawing its IP address. For example, if a first mobile handset registers to the IMS network, thus obtaining an IP address, but then does not use its IMS connection for a specified period of time, the network may withdraw its IP address and assign that address to a second mobile handset. In this case, the first handset is disconnected from the IMS network, and thus no longer IP accessible until it re-registers to the IMS network. When a handset loses its IP address and is disconnected from the IMS network, it can no longer participate in IP-based services.
  • PS packet-switched
  • Systems and methods described below allow another entity, such as another handset or a network entity, to send an IP -based message to a handset that lacks an IP address, in effect "waking up" the handset and causing it to initiate its own request for an IP address, so that it can receive the IP-based message.

  • IP network e.g., Internet 2220
  • the PPP session may be maintained even if the handset goes "dormant," so the handset will remain IP-accessible.

  • PCF packet control function
  • network operators in such networks typically choose to de-allocate IP addresses and tear down the PPP session in order to conserve IP addresses, if the mobile handset does not use its PPP session for a specified period of time. If the mobile handset 2210 does not have a PPP session, other entities cannot contact it via the IP network.
  • a mobile handset Even if a mobile handset is not IP-accessible, e.g., because the GSM/GPRS or CDMA network has de-allocated its IP address, it still has a connection to the circuit- switched (CS) network; as described above, the CS connection can be used to initiate and receive voice calls, SMS and other circuit-switched services.
  • CS circuit- switched
  • a mobile handset lacks an IP address and so cannot be directly contacted by another entity, the handset's existing CS connection can be exploited to cause the handset to initiate its own connection to the PS network.

  • One example is Unstructured Supplementary Services Data (USSD).
  • SN 2110 can also receive media traffic from content source(s) 2140, e.g., camcorders or digital cameras, and content server(s) 2150 that are capable of providing multimedia content 2160. This functionality is described in greater detail below.

  • SN 2110 communicates with CS network 2120 and IMS core 2130.
  • SN 2110 includes Load Balancer/ Admission Control 2221, which includes a series of load balancing functions that handle incoming signals from CS network 2120 and IMS core 2130.
  • Load Balancer/ Admission Control 2221 then passes the signals to Signaling Adaptation Layer (SAL) 2222, which aggregates the signals into a common internal form.
  • SAL Signaling Adaptation Layer
  • Call Leg Manager (CLM) 2223 then logically processes the aggregated signals.
  • call models used to describe telephone connections often split call states in one or more "call legs.”
  • GCCM General Call Session Manager
  • Control of call legs is discussed in greater detail in U.S. Patent Pub. No. 2006/0291488, the entire contents of which are incorporated herein by reference.
  • SN 2110 can also receive media traffic from content servers 2250, such as camcorders, external cameras, or proxies for same.
  • a logical function called the Media Leg Manager (MLM) 2240 handles this media traffic, using protocols such as RTP, IP, and/or RTSP.
  • Media traffic may also be re-directed by SN 2110 under roaming scenarios, as described in greater detail in U.S. Patent Pub. No. 2006/0291412, the entire contents of which are incorporated herein by reference.
  • SN 2110 may act as a proxy and retrieve content and media from such servers, then process it and transmit it to mobile handsets. In order to carry out these functions, SN 2110 supports various proxy functions.
  • SN 2110 supports a variety of combinational services, some examples of which are described below, and also provides an interface for supporting 3 rd party Application Servers (AS) 2255 (see, e.g., Fig. 6). These services, as stated earlier, generally involve contemporaneous circuit-switched and packet-switched connections. Some examples of such services as “See What I See” (SWIS) one "Image Ring” (IR) and “Ad Ring” (AR).
  • SWIS See What I See
  • IR Image Ring
  • AR Ad Ring
  • the architecture of SN 2110 includes SCF 2233 and Registrar 2235 components cooperatively to make such services possible. In those cases where an external media service is needed, the proxy components of SN 2110 may be used to receive the external media, process it internally for use in mobile handsets, and then transmit the media to the handsets.
  • SN may also use its mobility management components as described in greater detail in U.S. Patent Pub. No. 2006/0291412, the entire contents of which are incorporated herein by reference, to ensure that a favorable network connection is used to deliver the media to the roaming mobile handset.
  • services from the circuit-switched and packet-switched networks may be combined in various temporal sequences and modalities.
  • SN 2110 contains a Service Control Interaction Manager (SCIM) 234 component that uses policy driven service logic to resolve feature interactions when services are combined from different or the same networks are combined in various ways.

  • the PS logic only responds to messages from SN. And since it is only the SN that is aware of both the PS and CS connections and impending and ongoing call state information, the SN is useful in delivering and coordinating the advertisements.
  • the PA logic provides flexibility in which advertisements are shown when to the recipient. However, it is possible to envision a system in which the PA logic is not used to provide such flexibility.
  • a fixed rendering mechanism may be used (e.g., provided by the handset manufacturer) in the handset that employs a single algorithm to render the advertisements. This algorithm may be updated by sending an SMS message to the recipient handset. The user is then required to "click" on the received SMS message that causes a new algorithm to be loaded from the SN on to the handset.
  • PA 2185 A special piece of service logic installed in a user's handset is referred to as the Personal Agent (PA).
  • the basic architecture of PA 2185 assumes that the handset supports connections to both the circuit-switched (CS) network 2120 and the packet-switched (PS) network 2190, which are described in greater detail above.
  • CS circuit-switched
  • PS packet-switched
  • some handsets simultaneously support connections to both networks, and other handsets support a connection to only one network at a time.
  • the handset is assumed to support a number of CS signaling channels (CS Sch 1-n), and also a number of PS signaling channels (PS Sch 1-n).
  • CS Sch 1-n CS signaling channels
  • PS Sch 1-n PS signaling channels
  • the PA includes CS "Listener” 2321 and PS “Listener” 2322, which receive messages on the signaling channels (CS Sch 1-n) and (PS Sch 1-n), respectively.
  • CS Listener 2321 and PS Listener 2322 direct these messages to another service logic component called the “Dispatcher” 2330.
  • Dispatcher 2330 uses internal logic to direct the messages appropriately either to the handset's operating system (OS) 2350 or to the Combinational State Machine 2340.
  • Combinational State Machine 2340 handles the message according to its service logic. The actions of the combinational state machine are specific to the service that is being implemented.
  • the appropriate Listener in party B's handset receives the message and transmits it to the Dispatcher, which then sends it to the Combinational State Machine.
  • the Combinational State Machine in party B's handset interprets the message, terminates the CS voice call, initiates a PS connection to receive the picture and, after receiving the picture, terminates the PS connection. Then, the Combinational State Machine in party A's handset initiates a new CS voice call to party B's handset, and the parties can continue talking.
  • the service delivery platform has knowledge of both the CS and PS networks, the platform could be said to be aware of the circuit and packet components of combinational services.
  • the SN and the PA can be used together to synchronize a packet-switched connection with a circuit-switched connection in the user's handset, even if the handset itself cannot simultaneously support both kinds of connections.
  • the functional entities we will describe include a Media Player (MP) which is responsible for interpreting objects such as video clips, (streaming) real time video, audio clips, etc., that may use different encoding formats such as MPEG4; a functional entity called the Renderer that accepts as input a symbolic description of the object from the MP and is responsible for rendering the object on the A/V output of the handset.
  • MP Media Player
  • Renderer a functional entity called the Renderer that accepts as input a symbolic description of the object from the MP and is responsible for rendering the object on the A/V output of the handset.
  • handsets contain service logic that allows MP to access multimedia objects stored in the memory of the handset.
  • the MP is encapsulated within an application.
  • Handsets also typically contain service logic that takes the output of the Renderer and uses it to re-fresh the A/V outputs.
  • the video output of the Renderer is referred to as a Screen Buffer (SB), which is used to create the output for the display of the handset.
  • SB Screen Buffer
  • MP accesses the contents of the stored media for a selected object, retrieves said object, and interprets said object in terms specified by the Renderer interface. For example, consider a video clip stored in the memory of the handset. MP accesses this video clip, interprets the format of the clip, e.g., MPEG4, and creates a representation of the clip for processing by the Renderer. The Renderer accepts the representation from MP, processes it and creates a screen buffer. Service logic in the handset then reads the screen buffer and renders the video component on the display of the handset and the audio component on the speaker of the handset. Note that the Renderer is aware of the local hardware environment, e.g., size of the handset display, in order to create an appropriately sized screen buffer.
  • the screen buffer is refreshed by the Renderer as new information becomes available at an appropriate rate.
  • MP interprets the MPEG2 format and creates a representation of the clip that is then interpreted by the Renderer.
  • the Renderer is not, in general, familiar with the different formats and encodings of the multimedia objects. Instead, it relies on an internal representation (format) into which media players translate all objects that need to be rendered.
  • one of the Renderer's main functions is to create and maintain the screen buffer, e.g., the data structures and logical devices needed by the A/V system of the handset.
  • DRM Digital copy protection procedures
  • DRM-protected objects the objects can be shared without copying them using the methods described in greater detail below in the section entitled "Contemporaneous Rendering Without Violating Digital Rights.”
  • SDP Service Delivery Platform
  • Transmitting selected digital objects is a fundamental capability of the SDP.
  • the PA service logic resident in the handset
  • the PA aids in the selection of an object, creates a "network path" from the handset "A” to the SN from whence a second "network path” is created to the receiving handset.
  • Contents of the selected object are transmitted along these two paths, via the SN.
  • the setting up of the network paths is preceded by control information (“signaling") that aids in setting up the paths and the transmittal of the selected object is typically referred to as "bearer" traffic.
  • the two network paths are more typically referred to as "call legs.”
  • Embodiments of appropriate signaling protocols between the handsets and network entities is described in greater detail in U.S. Pat. Pub. No. 2007/0197227, attached as Appendix A, as well as in U.S. Patent Application No. 1 1/709,469, filed February 22, 2007 and entitled “System and Methods for Enabling IP Signaling in Wireless Networks.”
  • the rendering of the selected object may begin at both handsets independently, e.g., using the model described above. In some implementations it is not necessary for the entire copy of the selected object to exist on the handset "B" before rendering can be initiated. Rather, a fraction, i.e., a portion, of the said object is enough to start the rendering operation. This is typically referred to as "streaming.”
  • RTCP is an exemplary protocol that can be used, and other more timely constructs may be used as can other mechanisms that may be developed for this specific purpose.
  • FIG. 1 The architecture used for rendering multimedia objects contemporaneously on two handsets is illustrated in Fig. 1.
  • Initiator handset (I) 10 makes a voice call 11 to recipient handset (R) 12.
  • Initiator handset 10 exchanges options with recipient handset 12 via the SDP 20 to assess if recipient handset 12 is capable of the service.
  • SDP 20 gets indication from recipient handset 12, and notifies initiator handset 10 (e.g., with a "green" indicator) conveying that recipient handset 21 is capable of service.
  • Streamer 18 in initiator handset 10 takes the output from the initiator handset's renderer (Rl) 16 and sends it to the SDP 20.
  • SDP 20 adapts the format to a format conducive to the recipient handset 12.
  • Interceptor 28 in recipient handset 12 takes the information coming from SDP 20, and passes it to the recipient handset's Tenderer (R2) 26.
  • Renderer 26 displays on the screen of the recipient handset 12 what renderer (Rl) 16 is displaying at the initiator handset 10.
  • Initiator handset (I) makes a voice call to recipient handset (R);

  • SDP adapts the format to a format conducive to the recipient handset
  • Interceptor in recipient handset takes the information coming from SDP, and passes it to the recipient handset's renderer (R2);
  • Recipient handset's renderer displays on the screen of the recipient handset what renderer (Rl) is displaying at the initiator handset 10.
  • step (5) is optional as adaptation of the format by the SDP may not be necessary (e.g., when the recipient and the initiator handsets are the same handset model).
  • PA service logic in the first handset intervenes in the internal processing of the screen buffer, which is described in greater detail above, and encapsulates the contents of the screen buffer using an internal protocol (e.g., RTP).
  • This encapsulated information is then transmitted to the second handset, received by PA service logic resident in the second handset, de-encapsulated, and inserted into the screen buffer of the second handset from whence native service logic of the handset uses the newly inserted information to re-fresh the display.
  • An exemplary embodiment of the contemporaneous rendering of the multimedia objects is as follows. It is assumed in this exemplary embodiment that the two consumers engage in sharing a music video, i.e., the media sharing service allows a music video to be contemporaneously rendered on the two handsets.
  • An exemplary sequence is as follows:
  • Consumer A initiates phone call to consumer B;
  • PA logic resident in handset A is activated by the originating call event (most handset OS support native APIs that provide such event notifications);
  • PA(A) engages in capability exchange with PA(B) via SN to establish signaling and bearer paths for possible combinational service use;
  • Consumer A initiates media sharing service, for example by entering an appropriate command at handset A and selects the music video to be shared with consumer B;
  • PA(A) registers that selected media is DRM protected and initiates DRM- protection mode for sharing service
  • PA(A) intervenes in internal rendering process of handset A and reads screen buffer periodically at a pre-determined and programmed rate; 7. PA(A) encapsulates screen buffer information into a suitable format for transmittal to handset B via SN;
  • native service logic of handset A uses the contents of screen buffer to re-fresh the display of the handset A and to direct audio of the music video to the suitable audio out components of the handset, i.e., the rendering of the music video on handset A begins under control of the native service logic;
