Abstract

An open communications framework including an application layer that defines standards for applications, a middleware layer that defines standards for middleware, an operating system layer that defines standards for operating systems, and a hardware layer that defines standards for hardware. Interface layers based upon open-standards can be used to communicate data between the application layer and the middleware layer, between the middleware layer and the operating system layer, and between the operating system layer and the hardware layer.

Claims

1. A method for providing communications services using a services layer model for providing standards-based, open communications in a communications framework comprising:

providing a communications framework having a hardware-independent architecture with a services layer model, the communications framework specifying functional components capable of creating Next Generation Network (NGN) solutions, relationship of the components to each other, and interfaces between the components, the communications framework defining a layered network architecture that utilizes open standard interfaces to communicate between layers, the communications framework including;

an application layer configured for solution specific telecommunication applications;

an application services layer;

a middleware layer configured for middleware;

a platform services layer;

an operating system layer configured for a plurality of operating systems;

a modular hardware services layer; and

a hardware layer configured for a plurality of mechanical and electronic parts; and

providing communications services using the services layer model;

wherein the services layers are provided based upon open-standards to communicate data between the application layer and the middleware layer, between the middleware layer and the operating system layer, and between the operating system layer and the hardware layer;

wherein the services layers integrate open standards, open source software, and commercially available components into service providers'"'"' network delivery platforms so as to enable the delivery of multi-vendor services, content, and applications;

wherein the services layers interoperate to establish and maintain relationships among distributed, communication components so that solution integrators can utilize these service layers to properly position and map various communication standards and various commercial off the shelf (COTS) communication solutions to eliminate gaps and overlaps, thereby enabling the construction of communication solutions in a modular fashion;

wherein the application services layer is a layer of abstraction between the application layer and the middleware layer and is configured to include a plurality of open-standard and technology independent interfaces, each interface for communicating information between applications in the application layer and middleware in the middleware layer, so that a same application can access multiple network infrastructures, wherein services specified by the application services layer comprise protocol services, OAM&

P services, and telecommunication application services;

wherein the platform services layer is a layer of abstraction between the middleware layer and the operating system layer and is configured for a plurality of open-standard interfaces, each interface for communicating information between middleware in the middleware layer and operating systems in the operating system layer, wherein services specified by the platform services layer comprise IP workload management services, security intelligence and system modeling services, database modeling and connectivity services, and messaging services;

wherein the hardware services layer is a layer of abstraction between the operating system layer and the hardware layer and is configured for a plurality of open-standard interfaces, each interface for communicating information between operating systems in the operating system layer and hardware in the hardware layer, wherein services specified by the hardware services layer comprise storage services, hardware acceleration services, device drivers, firmware services, and hardware management services; and

wherein the operating system layer comprises carrier grade operating system enhancements including at least one of improved resource locking, heartbeat timers, hardened device drivers, low latency file systems, soft realtime task scheduling, and high performance process threading.

2. The method of claim 1, wherein at least one open standard is specified by the application layer to which applications of the application layer conform, and wherein at least one open standard is specified by the middleware layer to which middleware of the middleware layer conforms, and wherein at least one open standard is specified by the operating system layer to which operating systems of the operating system layer conforms, and wherein at least one open standard is specified by the hardware layer to which hardware of the hardware layer conforms.

3. The method of claim 1, wherein the middleware layer comprises signaling protocol stacks, gateway protocol stacks, parlay gateway components, parlay integration components, operation, administration, maintenance, and provisioning (OAM&

P) middleware components, database middleware, and Web services middleware.

4. The method of claim 1, wherein the operating system layer further comprises standard computer operating systems and embedded operating systems.

5. The method of claim 1, wherein the hardware layer comprises components for storage, input/output adaptors, network components, processors, and memory.

6. The method of claim 1, wherein the open standard interfaces of the application services layer comprise at least one standard selected from the group consisting of Open Mobile Alliance (OMA), Parlay, Open Systems Architecture (OSA), Second Generation Partnership Program (2GPP), Third Generation Partnership Program (3GPP), International Telecommunications Union (ITU), and Signaling Transport (SIGTRAN).

7. The method of claim 1, wherein the open standard interfaces of the application services layer comprises at least one standard selected from the group consisting of Session Initiation Protocol (SIP), Media Gateway Control Protocol (MGCP), Stream Control Transmission Protocol (SCTP), Universal Description, Discovery and Integration (UDDI), and Lightweight Directory Access Protocol (LDAP).

8. The method of claim 1, wherein the open standard interfaces of the application services layer comprises at least one standard selected from the group consisting of Simple Object Access Protocol (SOAP), eXtensible Markup Language (XML), Interface Definition Language (IDL), and Web Services Description Language (WSDL).

9. The method of claim 1, wherein the open standard interfaces of the platform services layer comprises at least one standard selected from the group consisting of Application Interface Specification (AIS), Carrier Grade Linux(CGL), and Open Cluster Framework (OCF), and Portable Operating System Interface (POSIX).

10. The method of claim 1, wherein the open standard interfaces of the platform services layer comprises at least one standard selected from the group consisting of Common Object Request Broker Architecture (CORBA), Remote Method Invocation/Internet Inter-ORB Protocol (RMI/IIOP), Simple Network Management Protocol (SNMP), and JAVA.

11. The method of claim 1, wherein the open standard interfaces of the hardware services layer comprises at least one standard selected from the group consisting of Hardware Platform Interface (HPI), Intelligent Platform Management Interface (IPMI), and Storage Management Initiative Specification (SMI-S).
