  • 3 Rd Generation Partnership Project 3 Rd Generation Partnership Project (3GPP) has defined a model IP communication network in Release 5 specification. These specifications are under continuous improvements and enhancements, such as Release 6, Release 7, to incorporate past experience, technology advancements, and future requirements.
  • 3GPP Technical Specification 3GPP TS 23.140 “Multimedia Messaging Service (MMS) (TS 23.140 v6.8.0 (2004-12)), which is herein incorporated by reference in its entirety, describes a method to send and receive digital content (e.g. text, image, audio, video, vector graphics etc.) from a mobile device. It also describes a standard architecture and elements (MMS User Agent, MMS Server/Relay, Message Store, HLR, MMS VAS Applications, and External Server) to support such service. These elements form a group represented as MMS Environment (MMSE). Chapter 4.3 of TS 23.140 describes the addressing scheme to be used for recipients. These schemes are E- Mail addresses (RFC 2822), MSISDN (E.164), and service provider specific address.

  • the sender User Agent does not have any control over the MM.
  • the scheme treats all addresses (MSISDN, E-Mail, or service provider specific) different even if it belongs to the same person or application. There is no method to unify these addresses and configure rules for controlling access, privacy, usage, expiry, compliance and synchronization control of the shared data. In the current scheme, if possible, these rules have to be set for individual addresses

  • the present invention solves the control problem by making all the elements involved in MMSE as Identity aware. What it means that these elements understand constructs of a digital identity as represented by a universal, abstract, persistent identifier such as XRI and are able to follow the controlling contracts based on persistent Identities.
  • An Identity refers to a representation of a real world identity entity that is capable of triggering a resource transfer and represents either an originating or a terminating end point in any sharing transaction referred to. during the course of this document. For representation, abstraction and resolution of these identities, an appropriate addressing scheme is used to uniquely and persistently identity users and the associated channel and / or applications.
  • An identity represents a user that has different identifiers for various channels and / or applications. Any such user could also have multiple distinct identifiers for the same channels and / or application. These identities can be associated to any subscribers, application, machines, etc.
  • IDENTIFIER An identifier is a construct used to define parameters of the sharing relationship that may exist vis-a-vis another user identity for / across various channels, networks, applications, domains etc.
  • the nature of identifiers used throughout the document include - Universal single, abstract , persistent and standard based identifier that encompasses several concrete identifiers representing same / different domains, channels and applications
  • absolute identifier (representing a non persistent, temporal identity of a user on a single domain and / or channel and / or application)
  • a multimedia resource can be either stream or a discrete format.
  • the ownership of the resource may either lie solely with the originator or jointly between the originating end point and the terminating end point identities, depending on the terms of the contract defined by the originating identity.
  • the resolution process refers to sequences of steps carried out to locate a real - world identity across same / different domains and / pr channels and / or applications.
  • Resolution Process for sharing of resource between 2 identities through SAP (single, abstract, persistent) Identifiers The process includes -

  • CONTRACT A contract refers to a defined structure that holds terms of data sharing from originating end point identity to terminating end point identity. It may represent enforceable rules pertaining to zero. or more resources, that extends multi-dimensional controls (access, privacy, usage, synchronization and compliance) to any / all resources shared and / or transferred by the originating end point identity to the terminating end point identity. Examples of controls extended would include enforced time based access to the shared resource, permissions associated with usage and / or distribution of the resource etc.

  • FIG. 2 is a block diagram that represents a real world identity as a universal, single, abstract, persistent (SAP) identifier.
  • This procedure is capable of encompassing various concrete identifiers belonging to different addressing domains through abstraction and static / dynamic resolution. For any inbound or outbound transaction based on these identifiers, the location of the relevant end point takes place based on a resolution process using a set of criteria which may depend on current set of attributes / preferences / presence information, etc pertaining to the real world entity at the respective end point.
  • Commonly used communication media like Email, IM, VoIP, etc. use single, concrete and absolute identifiers, to represent the end points for any transaction / communication. These identifiers may again be broadly classified into various standards such as the UR! and E.164.
  • the Identifier Abstraction and Resolution procedure converts these various formats into a SAP identifier, which is further processed by the communication framework to deliver the service required.
  • Figure 3 is a block diagram that represents the transfer / sharing of a resource from an originating real world entity to a terminating end point real world entity represented by universal single, abstract, persistent identifiers, while extending control (including but not limited to access, privacy, usage, expiry, compliance and synchronization control) of the said resource by means of enforcing contracts (extended or otherwise) defining the privileges associated with resource by the originating end point and the preferences associated with the receiving end point as defined through the current set of attributes or preferences or presence information pertaining to the terminating end point real world entity.
  • the underlying architecture When communication is sought by two or more identities the underlying architecture provides for a seamless addressing mechanism along with more advanced control of the resource and its representation for the identities involved in the communication.
  • the actual resource may or may not be transferred to the end point.
  • the resource may be retained at a common location or at the originator location and a representation or view of the resource may be presented to the end point.
  • the representation of the resource can also be enhanced using privileges set by the originator and preferences set by the end point identity. All preferences / settings which are set for a particular contract may be changed during the lifetime of the contract based on various access control mechanisms which may be built into the contract properties.
  • Figure 4 is a block diagram that represents the transfer / sharing of a resource from an originating real world entity represented through a universal single, abstract, persistent identifier to a terminating end point real world entity represented by a single, concrete, absolute identifier and vice versa, while extending control (including but not limited to access, privacy, usage, expiry, compliance and synchronization control) of the said resource by means of enforcing contracts (extended or otherwise) defining the privileges associated with resource by the originating end point.
  • control including but not limited to access, privacy, usage, expiry, compliance and synchronization control
  • the conversion from a SAP identifier to the traditional single, concrete, absolute identifier requires a conversion from the large set of features provided by the SAP addressing scheme to the limited set of features of the other identifiers.
  • This conversion may either be a simple static conversion to access the resource or a dynamic conversion.
  • Identities at originator end points can publish the digital data in three steps by selecting the data, selecting the receivers, and using the publish button to share the data.
  • the above can be carried out using a programmable button on a user / communication device.
  • the transfer / sharing of a resource by an originating real world entity represented by a single, concrete, absolute identifier, to a terminating real world entity represented through a universal single, abstract, persistent does not include extending control beyond access of the said resource.
  • the reception location of the resource however would be subject to the preferences associated with the receiving end point as defined through the current set of attributes or preferences or presence information pertaining to terms of the contract as set by the terminating end point real world entity with respect to the originator or otherwise.
