At least one call state control function (CSCF) entity generates subscriber-related queries according to an abstracted profile (AP) protocol. At an abstracted profile server (APS), a CSCF-generated, subscriber-related query is received, subscriber information is gathered related to the CSCF-generated, subscriber-related query from at least one subscriber information database using a native protocol of the subscriber information database, a reply message for the CSCF-generated, subscriber-related query is generated based on the gathered subscriber information and the reply message is forwarded to a respective CSCF that generated the CSCF-generated subscriber-related query, the reply message being forwarded according to the AP protocol.
RELATED APPLICATIONS This application claims the benefit of U.S. Provisional Patent Application Ser. No. 60/637,426 and U.S. Provisional Patent Application Ser. No. 60/637,337 both filed Dec. 17, 2004; the disclosure of each of which is incorporated herein by reference in its entirety.
TECHNICAL FIELD The subject matter described herein relates to multimedia services and more particularly to supporting database access in an Internet protocol multimedia subsystem network environment.
BACKGROUND Internet protocol (IP) multimedia subsystem (IMS) is defined by the Third Generation Partnership Project (3GPP) as a new mobile network infrastructure that enables the convergence of data, speech, and mobile network technology over an IP-based infrastructure. IMS bridges the gap between the existing traditional telecommunications technology and Internet technology, allowing network operators to offer a standardized, reusable platform with new, innovative services by enhancing real time, multimedia mobile services, such as voice services, video telephony, messaging, conferencing, and push services. IMS can be used to provide services for both mobile networks and fixed networks at the same time, providing unique mixtures of services with transparency to the end-user.
IMS supports the establishment of any type of media session (e.g., voice, video, text, etc.) and provides the service creator the ability to combine services in the same session and dynamically modify sessions �on the fly� (e.g., adding a video component to an existing voice session). As a result, new and innovative user-to-user and multi-user services become available, such as enhanced voice services, video telephony, chat, push-to-talk, and multimedia conferencing, all of which are based on the concept of a multimedia session. The underlying IMS infrastructure enables mobile IP communication services via its ability to find a user in the network and then to establish a session with the user. The key IMS components enabling mobility management are the call session control function (CSCF) and home subscriber server (HSS). The CSCF is essentially a proxy, which aids in the setup and management of sessions and forwards messages between IMS networks. The HSS holds all of the key subscriber information and enables users (or servers) to find and communicate with other end users.
SUMMARY In one aspect, the subject matter described herein includes a system for supporting database access in an IMS network environment. The system includes at least one CSCF entity for generating subscriber-related queries according to an abstracted profile (AP) protocol. The system also includes an abstracted profile server (APS) for receiving a CSCF-generated subscriber-related query and for gathering subscriber information related to the CSCF-generated subscriber-related query from at least one subscriber information database using a native protocol of the subscriber information database, generating a reply message for the CSCF-generated subscriber-related query based on the gathered subscriber information, and forwarding the reply message to a respective CSCF that generated the CSCF-generated subscriber-related query, the reply message being forwarded according to the AP protocol.
FIG. 9 is a block diagram illustrating an IMS cluster node 900 according to another embodiment of the subject matter described herein. IMS cluster nodes are described further in commonly-assigned U.S. Provisional Application No. 60/637,337, filed Dec. 17, 2004, entitled �Methods and Systems for Providing Subscriber Information to a Call State Control Function in an Internet Protocol (IP) Multimedia Subsystem (IMS),� the disclosure of which is incorporated by reference in its entirety. In FIG. 9, IMS cluster node 900 includes I-CSCF modules 902 and 904, S-CSCF modules 906 and 908, an internal communication bus 910, and APS 300 with an associated network interface card (NIC) 912. Internal communication bus 910 provides a communication path between the various printed circuit cards or processor modules in IMS cluster node 900. As such, any module may communicate with other modules in the IMS cluster node 900, such as I-CSCF module 904 and APS 300, via the internal communication bus 910. I-CSCF modules 902 and 904 may also have associated NICs 914 and 916. NICs 912, 914, and 916 are adapted to communicate with circuit switched and/or packet switched networks. I-CSCF modules 902 and/or 904 may include a subscription locator function (SLF) 918. SLF 918 is adapted to receive a communication session-related registration message, such as a session initiation protocol (SIP) REGISTER message, and identify an HSS entity 112 that contains a subscriber's location and subscription information. In the implementation illustrated by FIG. 9, HSS 112 is external to IMS cluster node 900 and accessed by APS 300 via NIC 912. In an alternative implementation illustrated by FIG. 10, HSS 112 functionality is included within IMS cluster node 900 as an HSS processor or module that is connected to internal communication bus 910. Once a subscriber's HSS 112 is identified, the subscriber's HSS 112 processor may be queried to determine the identity of a S-CSCF to which a communication session-related registration message should be forwarded. S-CSCF functionality may be included within IMS cluster node 900 as an S-CSCF processor or module that is connected to the internal communication bus as shown in FIGS. 9 and 10.
