## Title
Shared view of customers across business support systems (BSS) and a service delivery platform (SDP)

## Abstract

An identity management tool provides identity management across multiple domains, providing a single access point not only for information for runtime, network, and service layer information, but also for systems such as business support systems (BSS), operational support systems (OSS), and third party systems. The identity management tool creates a unified user profile that maps customer identities across the various domains, and presents the information in a virtual directory wherein the information appears to come from a single source, creating a central data hub for the various systems. This aggregation provides for the same experience and service across various access networks and using various channels. Such an architecture allows billing and service information to be shared with subscription and customer information, even though the data is substantially unrelated data from disparate data sources, without the need to combine schemas or aggregate the data into a single data store.

BACKGROUND OF THE INVENTION
The present invention relates generally to the management of data across a domain, an in particular to providing a common view and access point for customer information across multiple disparate data sources.
As an ever increasing number of services is being offered by various network providers, there is a corresponding increase in the number of systems, devices, applications, and components that utilize and store data for customers. While some of these data sources contain related data that can be easily aggregated or combined into a common schema, there are many sources that contain data that is considered to be substantially unrelated, or not easily aggregated, such that the data is not typically able to be accessed in a common fashion or point of entry. Further, companies may not wish to spend the time and money to generate common schemas or data repositories that are used across an entire domain.
For example, a telecommunications service provider typically maintains a large set of different repositories that each contain certain information about customers of that provider. FIG. 1 illustrates an example of an architecture 100 for such a provider. It can be seen that a number of systems and components reside behind the network and gateway layer 102, such as may include Business Support Systems (BSS) 104, a Service Delivery Platform (SDP) 106, Operational Support Systems (OSS) 108, and various other third party content and services 110. Each of these systems typically includes at least one repository containing a specific type of information, which generally is not substantially related or available to information in the repositories of the other systems.
For example, a BSS repository can store customer information from a service provider point of view, such as customer address information, customer billing information, products purchased by the customer, and campaigns to which a customer has responded. A BSS repository also can include subscription information for a customer, such as information for any voice, wireless, or roaming plan, as well as number of minutes purchased per month, etc. Such information is treated as product information from a BSS point of view, and the BSS repository also will include information as to whether a particular customer is subscribing to that product. If, for example, a customer subscribing to a new subscription is entitled to a new phone, that information typically will be maintained in the BSS repository. A BSS repository also typically is used to maintain trouble tickets, such as information regarding problems with service or failure to receive a form, as well as maintaining security credentials.
An OSS repository, on the other hand, is used for monitoring and administration of the system or other OSS operations such as charging/rating and activation provisioning. An OSS repository can also contain subscriber information such as information for the current and active bill for a customer, an inventory of assets associated with a customer, types of products or services provided to a customer, etc. A repository at the network level might include current network information for a customer, such as whether the customer is logged onto the network, a location of the customer on the network, whether a customer device is active, etc.
A service resource such as an SDP repository stores subscription information for a customer that is useful in running software services that are exposed to the customer, such as whether a particular customer has requested to receive news updates, and if so, also stores preference information such as which types of news the customer wishes to receive, e.g., international news or news related to a specific topic, as well as a channel in which to receive the news (e.g., SMS or MMS) and format information for the news (e.g., background color and font size). The SDP repository also can include information such as an identity for each customer, credentials, customer availability, etc.
There is other information that a telecommunications service provider may wish to combine with the SDP information. For example, a provider typically has to manage runtime information, such as presence and location information for a user on the network or other details related to the network activities, connectivity, etc. In addition to the context of a well factored-out service layer, the provider also manages dynamic information coming from the network, such as IMS Home Subscriber Service (IMS HSS) and Home Location Register (HLR) information. It can be desirable for all this information to be available to various services and applications.
Certain information overlaps or is related to other information stored for different services or in different repositories. Unfortunately, it is not practical for most entities to rewrite the schemas or redesign all the systems and services to use a common data model, single repository, single point of access, etc. As such, there typically is no way to treat the various repositories as a single data source that is readily available to applications, users, etc.
Certain approaches utilize a common database for all information related to principals such as subscribers. An exemplary architecture 200 for such an approach is shown in FIG. 2. In this example, data hubs 202 are used that are based on a common model, such as a customer data model or TMF (Telemanagement Forum) Shared Information/Data (SID) model. A problem with such an approach is that the common data model does not allow a system such as a BSS system to share data with the execution environment, which can include Home Subscriber Server (HSS) information, service specific data, presence information, etc., as the data is still maintained in silos at that level.
Further, a model such as that shown in FIG. 2 does not provide for identity management across the various systems (i.e., the possibility to associate credential, single sign-on, map/associate multiple identities to a same principal, anonymize some identities or federate the identities and repositories across multiple service providers/actors), and does not provide the tools needed to manage the identity of customers across the network, such as when a customer accesses a new service on the network or accesses the network using a new device. Further, functionality such as single sign-on and identity federation is not provided at the level of the customer data hub(s).
BRIEF SUMMARY OF THE INVENTION
Systems and methods in accordance with various embodiments of the present invention can overcome these and other deficiencies in existing systems by providing a common view and access point for multiple disparate data sources and systems across different data domains. Various tools provide for the mapping and management of identity across the domains, allowing for use of a single identities.
In one example, a common view of customer data is provided across data domains including a BSS data source, an OSS data source, a service layer or service delivery platform data source, a runtime data source, and a network data source. The data in the different domains can be stored according to different schemas and using different identifiers for the customer. A unified user profile is created that maps the identities of the customer across the various data domains to a single identity. A virtual directory is provided using the unified user profile that allows customer data from each of the data domains to be viewed and accessed by a user or application as if all the customer data is stored in a single repository and uses a single customer identifier. A user, service, application, or other entity or component is able to thus access the customer information in the data repositories through a single interface to the virtual directory.
Various tools provide for the management of identity across the various data sources and systems, allowing for such functionality as single sign-on and federated identities. A common access point thus allows for sharing of BSS, OSS, billing, and subscription information, along with other dynamic, runtime, service, and network information across different access networks, and allows different access channels to access the same services using the same settings, and sharing information already stored for the customer on the network. The common access point and managed identity also allows a user or application to concurrently update information related to a customer across the various domains, regardless of the where the data is stored.
A further understanding of the nature and the advantages of the inventions disclosed herein may be realized by reference of the remaining portions of the specification and the attached drawings.

DETAILED DESCRIPTION OF THE INVENTION
Systems and methods in accordance with various embodiments can overcome the aforementioned and other deficiencies in existing systems by providing a common view and access point for multiple disparate data sources and systems. Further, various tools provide for the management of identity across the various data sources and systems, allowing for such functionality as single sign-on and federated identities. For a telecommunications service provider, for example, a unified user profile (UUP) and common access point provides for sharing of BSS, OSS, billing, and subscription information, along with dynamic information (e.g., presence and location information) and service and network location information (e.g., HSS), across different access networks, and allows different access channels (e.g., broadband, cable, or wireless) to access the same services using the same settings, and sharing information already stored for the customer on the network.
A system in accordance with one embodiment provides a unified user profile and common access point that allows any system behind the network gateway to be accessed as a single source of information. At least one interface (e.g., an API) is provided that allows a user to access any information related to a given customer using the federated customer identity through a single access point. The access point and managed identity also allows a user or application to concurrently update information related to a customer across the various systems, regardless of the system(s) containing the information being updated.
One way in which this is achieved is through the use of a virtual directory, which provides the ability to view all the data across the domain. In one embodiment, a single API is used to provide access to multiple databases as if those databases were part of a common data source, and allows the information to be viewed as it the information was part of a single “virtual” directory. In creating the API, information from the various repositories can be aggregated with information coming from the service delivery platform. As illustrated in the exemplary architecture 300 of FIG. 3, a user request coming through the network and gateway layer should be able to interact with the service delivery platform 304, as well as systems and services such as BSS 306, OSS 308, and third party content and services 310. An identity management module or service 312 can be used to manage the unified user profile 314, as well as provide the vitural directory service 316 and provide for single sign-on service 318. In this case, the data from the BSS 306 and OSS 308 can be combined with data from the network layer 302, such as Home Location Register (HLR) or Home Subscriber Server (HSS) information, and aggregated with data from the service delivery platform 304, which can include information such as presence or location information for a customer.
It is likely that the identities used for each of the repositories will be different, even for a common customer (e.g., when coming from different access network or when considered in different domain (OSS, BSS and run time)). The identity management tool 312 is able to federate the identities across the various repositories, identifying identifiers for a single user and mapping those identities to a unified identifier that allows a user or application to access any of the data in any of the repositories using just the unified identifier, as the identity management tool 312 then can determine the appropriate identifier(s) to use for the necessary system(s). The identity management tool also can pull information for the customer from the various repositories using the unified profile information, and can present that information to the user or application in a virtual directory wherein the data appears to come from a single source.
In one example, identities are mapped to a single principal identity, and items from different repositories are mapped together using various tools or predefined schema mappings. Using the mappings, input from the different databases are aggregated and presented in an aggregated manner that instelf can be managed with the single principal identity.
A UUP can include a service resource such as an enabler that provides an identity managed virtual view of all the data about principals encountered in the SDP, including information such as credentials, subscriptions, service-specific data, network data (e.g., HSS), dynamic data (e.g., presence and location information), and profile information. The UUP provides for customizable schema mapping and caching or pre-fetching of data. The UUP also allows northbound interfaces to be wrapped and/or transformed as needed. These northbound interfaces can include, for example, interfaces such as Java (e.g., JNDI, JAX RPC, JAX WS), SOAP/HTTP (e.g., Rg Interface), LDAP, Diameter (e.g., Sh/Dh, Cx/Dx), OMA GSSM, and XCAP (e.g., OMA XDM profile enabler) interfaces. The UUP also can support “southbound” protocols including LDAP, XCAP, JDBC, Custom/Web service, and Diameter (e.g., Sh/Dh, Cx/Dx, HSS, SLS) protocols. The UUP can support various IMS profiles, customer data models, subscriber management features including integration with OSS/BSS, and various administration features.
A UUP also can be used to provide identity management across multiple domains including OSS, BSS, SDP or service layer, and network domains. For a service layer, the UUP can provide for the user of single sign-on features and partnership with third party providers. Identity management and federation are essential across service layer and access networks to enable consistent customer identification across access networks. Identity management shared with OSS/BSS is essential to allow shared OSS/BSS across access networks (e.g. common CRM or Subscription management).
The integration can also take advantage of a virtual directory that provides a virtually consolidated LDAP view of heterogeneous identity sources without requiring any synchronization. The virtual directory can connect OTB with LDAP and databases, and can provide a custom adapter that can support connections to any resource, such as Web services, to which Java can connect. A virtual directory also can provide various northbound (e.g., LDAP and DSML) and southbound (e.g., LDAP, database, custom) interfaces, as well as a join view that can combine data from multiple sources into a single virtual “super” entry.
In the example of FIG. 3, the service delivery platform (SDP) includes a horizontal, standards-based platform that abstracts the underlying network resources and follows a service-oriented architecture (SOA). Further information about such a service delivery platform is detailed in co-pending U.S. patent application Ser. No. 11/357,653, filed Feb. 16, 2006, entitled “FACTORIZATION OF CONCERNS TO BUILD A SDP (SERVICE DELIVERY PLATFORM),” which is hereby incorporated herein by reference. In one embodiment, the SDP utilizes a horizontal SOA platform based on the Java 2 Platform, Enterprise Edition (J2EE). The SDP includes a converged container based on Java Specification Requests JSR 116/289 and JSR 32, which includes SOA SIP AS, OSA AS, and telephony AS as a J2EE converged container. The SDP also exposes mobile, voice, and other communications enablers.
A service delivery platform such as is illustrated in FIG. 3 can build upon a standards based IT platform, such as an underlying J2EE core, and can make the platform carrier grade. The SDP can extend support beyond IP HTTP to support key protocols for telecommunications, for example, such as SIP/ISC, Diameter, and Parlay CORBA, for example, as well as adapters to messaging gateways. A standard or generic approach can be used to build adapters to any other resource or protocol using JCA 1.5. An SDP also can provide enablers as reusable components that abstract network resources and northbound interfaces. Services such as revenue services can be provided via IT and/or SOA functionality. The SDP also can provide support for SOA-based policies and business rules, as well as SOA-based integration of domains such as OSS domains with the SDP domain.
The SDP can include a number of enablers that can be implemented on, for example, SIP and Parlay. A presence enabler can be provided that follows OMA SIP/SIMPLE Presence, XDM, and RLS enabler specifications, which can aggregate presence from other networks and provide a northbound Parlay X interface for applications to use presence without participating in the presence network. Location data can be modeled as a presence attribute in one approach using an extensible presence data model. A multi-channel application-to-person (A2P) and person-to-application (P2A) messaging enabler can be sued that allows for sending and receiving of messages in channels like SMS, MMS, email, IM (XMPP), SIP, and others. A service level charging enabler can expose online, offline charging balance inquiry and tracking, pre-rated charging, etc., integrated to Ro/Rf (AAA media gateways), Parlay and Oracle BRM. A media server control enabler and voice access enabler can be used to control a wide variety of voiceXML servers, IVRs, announcement servers, and media servers (e.g. MSML, MSCML, MSCP, MGCP, . . . ). Protocols not available out of the box can be built on SIP AS or using JCA 1.5, for example.
FIG. 4 illustrates a first implementation 400 of a unified user profile (UUP) 402, wherein the UUP provides various applications in the SDP with concurrent network access to various directories and repositories/database management systems across the domain. Concurrent access can be provided via various methods, such as by using Identity Management (IdM), Lightweight Directory Access Protocol (LDAP v3), Directory Services Markup Language (DSML v2), and Diameter Sh and Cx. The UUP can include a highly extensible user profile with support for application-specific dynamic user views, and can provide support for Home Subscriber Server (HSS) and Subscription Location Function (SLF) functionality, as the views of the HSS or SLF (e.g., HLR) can be aggregated. If the northbound interface includes Diameter, for example, then it can behave similar to an HSS, and can extend the nature of the data provided. It can be advantageous to extend traditional network, OSS, or BSS data repositories by behaving similar to those repositories, but providing extensions via other data sources, using the same or an extended schema but the same interface, API, reference point, or protocol as the northbound interface that is exposed to others for accessing or interacting therewith. The user profile data can be managed using any appropriate data management system, such as the Oracle RDBMS server available from Oracle Corporation of Redwood Shores, Calif.
The UUP 402 also can be unified with a customer data hub in order to provide for all service-specific data, not just BSS information but also information such as privacy and preference information. The UUP also can overlap with dynamic data provided by Home Subscriber Server (HSS) 404 and Subscription Location Function (SLF) services, which can provide information such as presence and location information, along with a function such as HLR. By providing a common access point, the virtual directory provided by the UUP tool can also provide access to information such as account and billing information, subscription information, provisioning settings, and identity authorization and security information, for example. Identity management provided for the data hub through the UUP can include functionality such as single sign-on, identity federation, and anonymization. The authorization enabler and BSS can be used to provide for charging, messaging, and other functionality of an enabler framework via the identity management tool.
An advantage to such an approach is that the common view is not done from a static schema or data aggregation point of view. While schemas can certainly be combined and used with various embodiments, there is no need to combine schemas or aggregate data into a single data repository. Embodiments are able to combine views of the various data sources into a common view via the virtual directory, effectively combining information for a user from the various sources across the BSS and runtime of the network without the need to change any schemas or existing data models. The schemas can all be different, but the common view and identity management can hide these differences. For example, it is possible that all the data is simply lumped together. It then is also possible to use tools such as those provided by OVD to do a mapping in advance of fields that can be combined, cleaned using policies or scripts, or other such functions. This can be done in real time.
Such an approach also allows for a common view of types of data that typically are not combined in a traditional system. When aggregating data, systems typically combine data of similar types, such as BSS data from multiple BSS repositories (or OSS repositories). Other systems combine data from multiple sources to build a new data source. Embodiments described and suggested herein avoid the expense and work needed for such approaches by instead utilizing adapters built into sources of data that have not previously been combined, such as authorization data with presence data in such a system. Presence data, for example, is dynamically updated into a presence server, and is not related with authorization tables that an application is building, or related to billing or subscription information maintained by the BSS system. As such, this data would not have been combined using previous approaches. Embodiments herein, however, allow can provide a common view of data coming from completely different domains without altering anything about those domains, effectively combining data that would not have been considered to be common or related data before. Further, embodiments combine the customer data with information such as network state, location preference, and service preference, which was not previously provided in such systems.
