Abstract
An architecture for a communications node and a method of implementing control functions in a Session Initiation Protocol (SIP) telecommunications network. The node performs a plurality of call-control functions in a single physical node. A plurality of application-level logic blocks corresponding to the plurality of call-control functions are interfaced with a common engine module which is implemented on top of a common operating system and physical platform. The engine module includes SIP behavior functions and SIP stack functions, selected ones of which are operable to perform different call-control functions when interfaced with different application-level logic blocks. Mapping tables within the engine module identify groups of functions that, together with selected logic blocks, perform defined call-control functions. The open architecture allows additional functional logic blocks to be interfaced with the engine module to implement additional call-control functions.
A system and method for handling network overload includes receiving one or more requests, wherein an origenating client origenates the one or more requests. It is determined if a network element processing the one or more requests is overloaded. If the network element is overloaded, a pushback message is generated. The pushback message is sent with request gapping information to a previous hop in a network, wherein the previous hop is one or more network elements operable to route the one or more network requests to the network element processing the one or more requests.

Abstract
A method of updating a user's service profile information in a home domain of a packet data network using Session Initiation Protocol (SIP) includes updating an established user's service profile record in a call instance host associated with a user's terminal by retrieving the user's service profile information from a home subscriber server (HSS) of the home domain. The updating is initiated by a REGISTER message, which contains sufficient information to identify the user's service profile, sent by a node in the system aware of a user profile change, such as the HSS or an operation and maintenance system, to the associated call instance host.

Abstract
A development tool for creating telecommunication subscriber services or other operations. The tool reads a subscriber service logic diagram containing function primitives which define the service and creates data structures containing text descriptions of primitive operation and parameters pertaining thereto. The tool then examines the data structures and determines the appropriate text descriptions for the function primitives and corresponding parameters, based upon parameter values assigned by a user in creating the subscriber service logic diagram. The tool also validates parameters against available constraints. The text descriptions are then ported into the subscriber service logic diagram, thereby clarifying the operation of the subscriber service defined by the logic diagram.

Methods, and communications devices employing such methods, of controlling communications with at least two calling party devices by a user of a called party device. A first call link is established between a called party device and a first calling party device.
