Various exemplary embodiments relate to a method of routing Diameter requests. The method includes: receiving an initial request from a client, the initial request including a session identifier, an initial destination realm, and request content; determining a Diameter route for the initial request based on the destination realm and the request content; forwarding the initial request according to the Diameter route; receiving a response to the initial request; extracting an origin realm or host from the response; and storing the origin realm or host in association with the session identifier. Various exemplary embodiments relate a Diameter Routing Agent (DRA) configured to perform the above method. Various exemplary embodiments relate to a non-transitory machine-readable storage medium encoded with instructions for performing the method.

Various exemplary embodiments relate to a method and related network node including one or more of the following: determining a session to roll over; determining whether usage monitoring at a usage monitoring node is currently disabled for the session; and if usage monitoring at the usage monitoring node is currently disabled for the session, sending a message from the session management node to the usage monitoring node, wherein the message includes an instruction to enable usage monitoring for the session. Various alternative embodiments additionally include one or more of the following: waiting for a length of time to receive a usage report at the session management node from the usage monitoring node; wherein the step of sending a message from the session management node to the usage monitoring node is only performed when a usage report is not received during the length of time.

A system and method for simplifying management information discovery in a Triple Play provider network involves configuring an element management system (EMS) database to store DHCP information, and configuring the EMS to serve the information to a subscriber service controller or other operations support services component.

A method and a tool for provisioning media gateway resources in a network management context are presented. Circuit emulation entities are selected via the interaction with the tool in a combination of configuration and selection contexts. Further circuit emulation entity identification may be effected by using a combination of filter options. Once a list of identified circuit emulation entities is generated, a determination is made as to which entities are available. Connection control over all selected available circuit emulation entities is either relinquished or regained via a network management system by interacting with the tool. Relinquishing connection control for the selected circuit emulation entities includes, but is not limited to, configuring thereof for H.248 signaling, configuring port buffers, reserving resources at network nodes. The advantages are derived from a bulk media gateway provisioning at reduced costs lowering entry barriers in migrating circuit-switched service content transport over a packet-switched infrastructure.

The invention provides a system and method of retrieving data associated with a file from a database by a field name into local memory. It comprises calculating an address reference for a storage location in the local memory for the data; fetching the data from the database; and utilizing the address reference to map the data to an address in the local memory. The address reference is an offset value from a base address of the storage location. Several files may be accessed using a cross reference table containing pointers to field tables. Entries in the cross reference table point to a field table. Each field table is a list of fields associated with the file. Each entry in the field table is a calculated offset value providing an address offset of a particular field from the base address of the file.
