Methods, systems, and computer program products for clustering and communicating between Internet protocol multimedia subsystem (IMS) entities and for supporting database access in an IMS network environment. According to one aspect, an IMS cluster node includes a serving call state control function (S-CSCF) for controlling media sessions between IMS users. The cluster node further includes a home subscriber service (HSS) function for storing and providing IMS subscription information to the S-CSCF function. A shared memory is operatively associated with the S-CSCF function and the HSS function. The S-CSCF function obtains IMS subscription information from the HSS function via the shared memory.

A method for providing presence gateway functionality includes deriving presence information for subscribers in a first set of subscribers based on telecommunications signaling messages. The first set of subscribers includes at least one subscriber who is not a subscribed-to presentity. The method also includes determining whether presence status information for a subscriber in the first set of subscribers has changed. In response to detecting a change in presence status, it is determined whether the subscriber is a subscribed-to presentity. If the subscriber is a subscribed-to presentity, a presence server is notified of the change in status of the subscriber.

Methods, systems, and computer program products for supporting database access in an Internet protocol (IP) multimedia subsystem (IMS) network environment are disclosed. 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.

A filtering and application triggering platform may be implemented on a signaling message routing node to decode signaling messages and increase efficiency in subsequent processing of the signaling message. A communications link module on a signaling message routing node receives a signaling message. A first filtering and application triggering module associated with the communication link module extracts predetermined parameters from the signaling message and generates a decode key based on the parameters. The first filtering and application triggering module applies a first triggering rule to the decode key and determines whether to forward or drop the message. If the first filtering and application triggering module determines that the message should be forwarded, the first filtering and application triggering module forwards the message to another processing module within the signaling message routing node. The decode key is forwarded along with the message. The next processing module may extract additional parameters from the message, add the parameters to the decode key, and apply a triggering rule to the modified decode key.

A short message gateway may include signal transfer point (STP) functionality, mobile originating short message service center (SMSC) functionality, and short message delivery peer-to-peer (SMPP) gateway functionality. The short message gateway may receive an SS7 message including a short message payload. The short message gateway may formulate an SMPP message including the short message payload and access one or more internal address resolution and/or number portability databases to determine the destination address for the SMPP message. The short message gateway may then forward the SMPP message to its destination.

Methods and system for delivering presence information regarding push-to-talk subscribers are disclosed. In one method, a short message gateway receives presence information from a first push-to-talk subscriber from a presence or push-to-talk server. The short message gateway determines the location and availability of a second push-to-talk subscriber to which the presence information is directed. If the second push-to-talk subscriber is available, the SMS gateway delivers the presence information to the second push-to-talk subscriber in a manner that bypasses the SMSC. If the SMS gateway determines that the second push-to-talk subscriber is not available, the SMS gateway discards the presence information.

A routing node () includes a usage measurements module () for polling internal processing modules () and communication link modules (, and) for usage measurements collected by these modules and forwarding the usage measurements to a general-purpose computing platform () via a high speed communication link (). The usage measurements module () may include load sharing functionality that allows distribution of usage measurements collection among multiple usage measurements modules. The usage measurements module () may also include a reports generator for generating user-configurable reports.
