## Background
CROSS-REFERENCES TO RELATED APPLICATIONS
The present application claims benefit under 35 USC 119(e) of U.S. Provisional Application No. 61/301,827, filed on Feb. 5, 2010 by Maes and entitled “Service Based Consolidation of Applications Across Networks,” of which the entire disclosure is incorporated herein by reference for all purposes.


BACKGROUND OF THE INVENTION
Embodiments of the present invention relate generally to methods and systems for supporting interactions in communication sessions and more particularly to consolidating applications or services across networks to allow the applications or services to be available on networks of different types.
Various types of “legacy” networks such as the Internet, Public Switch Telephone Network (PSTN), and various other types of fixed and mobile communication networks are also in common use. A great many applications have been developed for and specific to these networks. For example, such applications in a telecommunication environment can include applications for performing various services like conferencing, call forwarding, etc as well as various accounting, i.e., charging or billing, subscriber management, and other functions. Additionally, new networks, i.e., “next generation networks,” such as Internet Protocol (IP) Multimedia Subsystem (IMS) networks and various IP-based networks have been and are being developed to support communication sessions and services related thereto. However, the “legacy” written for one of the legacy networks are typically not portable. That is, the applications cannot be moved from one legacy network to another or from a legacy network to a next generation network. Furthermore, the applications or services operating on one network, i.e., in a protocol supported by that network, are typically not available on another, different type of network even if that other network is accessible. However, these legacy applications may still be useful and valuable and replacing or modifying these legacy applications to operate on or interact with other networks can be costly and time consuming. Hence, there is a need for improved methods and systems for allowing applications or services to be available across networks of different types.
BRIEF SUMMARY OF THE INVENTION
Embodiments of the invention provide systems and methods for consolidating applications or services across networks to allow the applications or services to be available on networks of different types. According to one embodiment, a method for consolidating applications across a plurality of networks of different types can comprise receiving at a service layer component a communication in a communication session from a first communication network of the plurality of networks. The communication can be in a first protocol. The communication can be translated from the first protocol to a second protocol with the service layer component of based on a state of the communication session. The first protocol can be different from the second protocol. The translated communication can be provided to a component of a second network of the plurality of networks.
For example, the service layer component can comprise a Service Delivery Platform (SDP). In such cases, providing the second communication to the component of the second network comprises providing the second communication to a northbound interface of an enabler of the SDP. Additionally or alternatively, providing the second communication to the component of the second network can further comprise providing the second communication to a Session Initiation Protocol (SIP) servlet of the SDP and the second protocol comprises SIP.
The first communication can be from a client of the first network and providing the translated communication to the component of the second network can comprise providing the translated communication to a service of the second network. Additionally or alternatively, the first communication can be from a service of the first network and providing the translated communication to the component of the second network can comprise providing the translated communication to a client of the second network.
According to another embodiment, a system can comprise a first network operating on a first protocol, a second network operating on a second protocol, wherein the second protocol is different from the first protocol, and a service delivery platform (SDP) communicatively coupled with the first network and the second network. The service delivery platform can be adapted to translate communications of the first network and second network between the first protocol and the second protocol.
The SDP can further comprise one or more enablers communicatively coupled with the next generation network and adapted to provide a northbound interface abstracting the underlying network technologies of the next generation network. In some cases, the SDP can further comprise a Session Initiation Protocol (SIP) servlet. In such cases, translating communications between the protocol of the legacy network and the protocol of the next generation network can comprise translating communications between the protocol of the legacy network and the protocol of the next generation network to SIP. Additionally or alternatively, a service can be communicatively coupled with the first network and a client communicatively coupled with the second network. In such cases, the SDP can be adapted to receive a communication in a first protocol from the service, translate the message from the first protocol to a second protocol different from the first protocol, and provide the translated message to the client. Additionally or alternatively, a client can be communicatively coupled with the first network and a service communicatively coupled with the second network. The SDP can be adapted to receive a communication in a first protocol from the client, translate the message from the first protocol to a second protocol different from the first protocol, and provide the translated message to the service.
According to yet another embodiment, a machine-readable medium can have stored thereon a series of instruction which, when executed by a processor, cause the processor to consolidate applications across a plurality of networks of different types by receiving at a service layer component a communication in a communication session from a first communication network of the plurality of networks. The communication can be in a first protocol. The communication can be translated from the first protocol to a second protocol with the service layer component of based on a state of the communication session. The first protocol can be different from the second protocol. The translated communication can be provided to a component of a second network of the plurality of networks.
For example, the service layer component can comprise a Service Delivery Platform (SDP). In such cases, providing the second communication to the component of the second network comprises providing the second communication to a northbound interface of an enabler of the SDP. Additionally or alternatively, providing the second communication to the component of the second network can further comprise providing the second communication to a Session Initiation Protocol (SIP) servlet of the SDP and the second protocol comprises SIP.
The first communication can be from a client of the first network and providing the translated communication to the component of the second network can comprise providing the translated communication to a service of the second network. Additionally or alternatively, the first communication can be from a service of the first network and providing the translated communication to the component of the second network can comprise providing the translated communication to a client of the second network.

DETAILED DESCRIPTION OF THE INVENTION
In the following description, for the purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of various embodiments of the present invention. It will be apparent, however, to one skilled in the art that embodiments of the present invention may be practiced without some of these specific details. In other instances, well-known structures and devices are shown in block diagram form.
The ensuing description provides exemplary embodiments only, and is not intended to limit the scope, applicability, or configuration of the disclosure. Rather, the ensuing description of the exemplary embodiments will provide those skilled in the art with an enabling description for implementing an exemplary embodiment. It should be understood that various changes may be made in the function and arrangement of elements without departing from the spirit and scope of the invention as set forth in the appended claims.
Specific details are given in the following description to provide a thorough understanding of the embodiments. However, it will be understood by one of ordinary skill in the art that the embodiments may be practiced without these specific details. For example, circuits, systems, networks, processes, and other components may be shown as components in block diagram form in order not to obscure the embodiments in unnecessary detail. In other instances, well-known circuits, processes, algorithms, structures, and techniques may be shown without unnecessary detail in order to avoid obscuring the embodiments.
Also, it is noted that individual embodiments may be described as a process which is depicted as a flowchart, a flow diagram, a data flow diagram, a structure diagram, or a block diagram. Although a flowchart may describe the operations as a sequential process, many of the operations can be performed in parallel or concurrently. In addition, the order of the operations may be re-arranged. A process is terminated when its operations are completed, but could have additional steps not included in a figure. A process may correspond to a method, a function, a procedure, a subroutine, a subprogram, etc. When a process corresponds to a function, its termination can correspond to a return of the function to the calling function or the main function.
The term “machine-readable medium” includes, but is not limited to portable or fixed storage devices, optical storage devices, wireless channels and various other mediums capable of storing, containing or carrying instruction(s) and/or data. A code segment or machine-executable instructions may represent a procedure, a function, a subprogram, a program, a routine, a subroutine, a module, a software package, a class, or any combination of instructions, data structures, or program statements. A code segment may be coupled to another code segment or a hardware circuit by passing and/or receiving information, data, arguments, parameters, or memory contents. Information, arguments, parameters, data, etc. may be passed, forwarded, or transmitted via any suitable means including memory sharing, message passing, token passing, network transmission, etc.
Furthermore, embodiments may be implemented by hardware, software, firmware, middleware, microcode, hardware description languages, or any combination thereof. When implemented in software, firmware, middleware or microcode, the program code or code segments to perform the necessary tasks may be stored in a machine readable medium. A processor(s) may perform the necessary tasks.
Embodiments of the invention provide methods and systems for consolidating applications across a plurality of networks of different types. Generally speaking, consolidating applications across a plurality of networks of different types can be performed by using a service level component such as s Service Delivery Platform (SDP) as will be described in greater detail below to perform mapping and translation between the protocols of the different networks. Additionally, and as will also be described in greater detail below, the SDP can be implemented in a manner to allow the SDP to abstract the underlying network technologies of the next generation network so as to allow the legacy applications to interact with or participate in communications with services, components, clients, etc, of the next generation network without needing to be aware of the protocols and other technologies thereof. Furthermore, the SDP can perform translation of messages to and from components of the different networks, for example to an intermediate or common protocol such as SIP
More specifically, consolidating applications across a plurality of networks of different types can comprise receiving at a service layer component, such as an SDP, a communication in a communication session from a first communication network of the plurality of networks. The communication can be in a first protocol, i.e., a protocol of the first network. The communication can be translated from the first protocol to a second, different protocol within the service layer component based on a state of the communication session. The translated communication can be provided to a component of a second network of the plurality of networks. For example, providing the second communication to the component of the second network can comprises providing the second communication to a northbound interface of an enabler of the SDP. Additionally or alternatively, providing the second communication to the component of the second network can comprise providing the second communication to a Session Initiation Protocol (SIP) servlet of the SDP and the second protocol can comprise SIP. So, for example, the first communication can be from a client of the first network and providing the translated communication to the component of the second network can comprise providing the translated communication to a service of the second network. Conversely, the first communication can be from a service of the first network and providing the translated communication to the component of the second network can comprise providing the translated communication to a client of the second network. In this way, services can be provided, i.e., consolidated, across networks, even if the networks are of different types. Various additional details of embodiments of the present invention will be described below with reference to the figures.

These user computers 105, 110 may also have any of a variety of applications, including one or more development systems, database client and/or server applications, and web browser applications. Alternatively, the user computers 105, 110 may be any other electronic device, such as a thin-client computer, Internet-enabled mobile telephone, and/or personal digital assistant, capable of communicating via a network (e.g., the network 115 described below) and/or displaying and navigating web pages or other types of electronic documents. Although the exemplary system 100 is shown with two user computers, any number of user computers may be supported.
In some embodiments, the system 100 may also include a network 115. The network may can be any type of network familiar to those skilled in the art that can support data communications using any of a variety of commercially-available protocols, including without limitation TCP/IP, SNA, IPX, AppleTalk, and the like. Merely by way of example, the network 115 maybe a local area network (“LAN”), such as an Ethernet network, a Token-Ring network and/or the like; a wide-area network; a virtual network, including without limitation a virtual private network (“VPN”); the Internet; an intranet; an extranet; a public switched telephone network (“PSTN”); an infra-red network; a wireless network (e.g., a network operating under any of the IEEE 802.11 suite of protocols, the Bluetooth protocol known in the art, and/or any other wireless protocol); and/or any combination of these and/or other networks such as GSM, GPRS, EDGE, UMTS, 3G, 2.5 G, CDMA, CDMA2000, WCDMA, EVDO etc.
The system may also include one or more server computers 120, 125, 130 which can be general purpose computers and/or specialized server computers (including, merely by way of example, PC servers, UNIX servers, mid-range servers, mainframe computers rack-mounted servers, etc.). One or more of the servers (e.g., 130) may be dedicated to running applications, such as a business application, a web server, application server, etc. Such servers may be used to process requests from user computers 105, 110. The applications can also include any number of applications for controlling access to resources of the servers 120, 125, 130.

The web pages created by the web application server may be forwarded to a user computer 105 via a web server. Similarly, the web server can receive web page requests and/or input data from a user computer and can forward the web page requests and/or input data to an application and/or a database server. Those skilled in the art will recognize that the functions described with respect to various types of servers may be performed by a single server and/or a plurality of specialized servers, depending on implementation-specific needs and parameters.
The system 100 may also include one or more databases 135. The database(s) 135 may reside in a variety of locations. By way of example, a database 135 may reside on a storage medium local to (and/or resident in) one or more of the computers 105, 110, 115, 125, 130. Alternatively, it may be remote from any or all of the computers 105, 110, 115, 125, 130, and/or in communication (e.g., via the network 120) with one or more of these. In a particular set of embodiments, the database 135 may reside in a storage-area network (“SAN”) familiar to those skilled in the art. Similarly, any necessary files for performing the functions attributed to the computers 105, 110, 115, 125, 130 may be stored locally on the respective computer and/or remotely, as appropriate. In one set of embodiments, the database 135 may be a relational database, such as Oracle 10 g, that is adapted to store, update, and retrieve data in response to SQL-formatted commands.
FIG. 2 illustrates an exemplary computer system 200, in which various embodiments of the present invention may be implemented. The system 200 may be used to implement any of the computer systems described above. The computer system 200 is shown comprising hardware elements that may be electrically coupled via a bus 255.

FIG. 3 is a block diagram illustrating, at a high-level, functional components of a system for consolidating applications across a plurality of networks of different types according to one embodiment of the present invention. In this example, the system 300 includes a first network 310 such as a Public Switch Telephone Network (PSTN), or various other one or more fixed and mobile communication networks or even a next generation network such as an Internet Protocol (IP) Multimedia Subsystem (IMS) networks and various IP-based networks. A first network application or service 311 can be communicatively coupled with the first network 310 and can be adapted to provide services and/or interact with one or more clients 312 of the first network 310 as known in the art.
The system can also include a second network 315. For example, such a network 315 can comprise any type of legacy or next generation network as described above but is of a different type and operates on a different protocol from the first network 310. A second network application or service 316 can be communicatively coupled with the second network 315 and can be adapted to provide services and/or interact with one or more clients 317 of the second network 315 as known in the art.
The system 300 can also include a Service Delivery Platform (SDP) 305 communicatively coupled with the first network 310 and the second network 315. According to one embodiment, the SDP 305 can abstract the underlying networks 310 and 315 and/or resources, e.g., services 311 and 316, so as to allow applications and/or services to access the network, resources, services, etc. of the other network in a way independent of the underlying network(s) and or resource(s) and the technologies upon which they may be implemented. Such a SDP can be implemented, for example, as described in U.S. patent application Ser. No. 11/357,653, filed Feb. 16, 2006, by Maes and entitled “Factorization of Concerns to Build a SDP (Service Delivery Platform)” of which the entire disclosure is incorporated herein by reference for all purposes.
More specifically, the SDP 305 can include one or more enablers 340-350 communicatively coupled with the networks 310 and 315. As used herein, the term enabler refers to a reusable service layer component or components that provide a function for use by others (other enablers, applications (i.e. services) or any authorized resource) through appropriate northbound interfaces. These functions may be implemented by network resources, devices or OSS/BSS functions. An enabler accesses these resources and/or functions via any mechanism appropriate for the resource. That is, a southbound interface is not specified as part of the adapter, so it can be changed from resource to resource. However, northbound interfaces provided by an enabler may be standardized. The enablers 340-350 can include any one or more of the enablers described, for example, in U.S. patent application Ser. No. 12/544,484 filed Aug. 20, 2009 by Maes and entitled “Charging Enabler”, U.S. patent application Ser. No. 11/949,930 filed Dec. 4, 2007 by Maes and entitled “Call Control Enabler Abstracted from Underlying Network Technologies”, a media server control enabler as described in U.S. patent application Ser. No. 11/877,129 filed Oct. 23, 2007 by Maes and entitled “Network Agnostic Media Server Control Enabler”, an intelligent messaging enabler as described in U.S. patent application Ser. No. 11/939,705 filed Nov. 14, 2007 by Maes and entitled “Intelligent Message Processing” of which the entire disclosure of each is incorporated herein by reference for all purposes. Other types of enablers are contemplated and considered to be within the scope of the present invention.
Thus, the enablers 340-350 provide southbound interfaces specific to the underlying network technologies, i.e., of the networks 310 and 315, that allow access to the different networks. The enablers 340-350 also provide northbound interfaces that provide a way to compose, impose policies on, build application access, etc. the underlying networks and communications thereon. According to one embodiment, the SDP 305 can also include a translation module 335 communicatively coupled with the enablers 340-350. The translation module can be adapted to translate between the northbound interfaces of the enablers 340-350 and the protocols of the networks 310 and 315. For example, the specific protocols of the networks 310 can be converted to Session Initiation Protocol (SIP) by the translation module 335. In this way, the SDP 305 or other service layer component can be adapted to interact with the networks 310 and 315 or resources or other components thereof, e.g., services 311 and 316 or clients 312 and 317, regardless of and independent from the underlying network technologies. Furthermore, this abstraction allows the SDP to make the service 311 of the first network 310 available to the client of the second network 317 and the service 316 of the second network 315 available to the client of the first network 312.
As noted above, the SDP 305 described herein can be implemented according to the methods and systems described in the referenced applications entitled “Factorization of Concerns to Build a SDP (Service Delivery Platform)” and “Service Delivery Platform Based Support of Interactions Between Next Generation Networks and Legacy Networks.” As noted therein, such an SDP can be implemented, e.g., via a set of one or more enablers, to abstract the underlying protocols and technologies of the networks on which a communication session is occurring. Furthermore, the SDP 305 can translate the various protocols, for example to SIP or another protocol, and handle or process the communications based on the translated messages. A portion of the application entitled “Service Delivery Platform Based Support of Interactions Between Next Generation Networks and Legacy Networks” is reproduced here for the sake of convenience.
FIG. 4 is a block diagram illustrating additional details of a system for consolidating applications across a plurality of networks of different types according to one embodiment of the present invention. More specifically, this example illustrates an SDP 305 which, as noted above, can be adapted to support interactions in a communication session as described herein. In this example, the SDP 305 includes a number of adapters 410-422 for providing an interface between the SDP 305 and any number of networks and/or resources of various types. For example, these adapters 410-422 can include but are not limited to one or more JCA 1.5 adapters 410 such as a Parlay adapter 411, a Diameter adapter 412, and others 413, an HTTP adapter 415, a SIP adapter 416, and one or more Transaction Capabilities Application Part (TCAP) adapters 417 such as adapters for INAP 418, CAP 419, WIN 420, AIN 421, and others 422.
The SDP 305 can also include an enabler framework 440. The enabler framework 340 can include an OSA application server 441 implemented, for example, in Parlay JR, Parlay X etc. The enabler framework 340 may additionally or alternatively include a SIP servlet container 442 providing functions such as a proxy, registrar, location services, etc. The enabler framework 340 may additionally or alternatively include a Signaling System 7 (SS7) server 443 adapted to implement or provide IP Multimedia Service Control Functions (IM-SCF) 430, IP Multimedia Service Switching Functions (IM-SSF) 431, and other functions.
Enablers of the enabler framework 440 can include but are not limited to: Messaging 446, e.g., application to person and person to application multi-channel messaging able to support email, SMS, MMS, IM, Voice Messages and SIP; Presence 452, e.g., Presence, XDM and RLS enabler functions that can be aggregated across multiple presence-enabled networks and sources; Call control 450, e.g., generic, 3rd party and multi party call control (voice and media) realizable on many network technologies application routing/dispatching independently of the network technology; Media server control 454, e.g., media processing, mixing and streaming control realizable against many network and media server technologies; Voice Access 448, e.g., inclusion of voice and DTMF dialogs in a call/interaction with a user; Web and mobile access (not shown here), e.g., multi-channel portal including associated supporting technologies such as device recognition, device repository, adaptation and delivery to multiple channels; Charging 444, e.g., service level on-line and offline charging including Balance check/tracking, pre-rated charges, delegated rating and rate inquiries; Device Management (not shown here), e.g., device and network resource provisioning, policy execution, enforcement and management providing functions such as PDP (Policy Decision Point), PEP (Policy Enforcement Point), PEEM (callable and proxy mode), PE.; and others. One or more custom enablers 451 can also be included or added. Providing additional/new enablers or extending them can be accomplished by developing new J2EE components with northbound interfaces, following the enabler principles and reusing the enabler framework functions or by developing new adapters using standard technologies and recipes (e.g. JCA 1.5, SIP, HTTP, etc.) to integrate existing enabler with new resources, protocols or network technologies.
The SDP 305 can include applications for providing or supporting VoIP services 456, a virtual PBX 458, a telephony application server 460, etc. The SDP 305 can also include applications for supporting or providing chat services 455, one or more custom services 460, content delivery 465, identity management 438, etc.
As noted above, the SDP 305 can abstract the underlying networks and/or resources, e.g., services, so as to allow applications and/or services to access the networks, resources, services, etc. of other networks in a way independent of the underlying network(s) and or resource(s) and the technologies upon which they may be implemented. That is, this abstraction allows the SDP to make the service of one network available to the clients and/or service of another network that may be of a different type and operating on a different protocol.
In the foregoing description, for the purposes of illustration, methods were described in a particular order. It should be appreciated that in alternate embodiments, the methods may be performed in a different order than that described. It should also be appreciated that the methods described above may be performed by hardware components or may be embodied in sequences of machine-executable instructions, which may be used to cause a machine, such as a general-purpose or special-purpose processor or logic circuits programmed with the instructions to perform the methods. These machine-executable instructions may be stored on one or more machine readable mediums, such as CD-ROMs or other type of optical disks, floppy diskettes, ROMs, RAMs, EPROMs, EEPROMs, magnetic or optical cards, flash memory, or other types of machine-readable mediums suitable for storing electronic instructions. Alternatively, the methods may be performed by a combination of hardware and software.
While illustrative and presently preferred embodiments of the invention have been described in detail herein, it is to be understood that the inventive concepts may be otherwise variously embodied and employed, and that the appended claims are intended to be construed to include such variations, except as limited by the prior art.
