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.

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.

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. The called party device then receives a call request from a second calling party device; e. g. , a call-waiting indication. A user of the called party device places the first call link on hold, and accepts the call request from the second calling party device to establish a second call link between the called party device and the second calling party device. While the user of the called party device is in communication with the user of the second calling party device, the user can cause a message to be transmitted to the first calling party device, whereby the user of the called party device can communicate information to a user of the first calling party device without interrupting communications with a user of the second calling party device. A message to the first calling party device can, for example, instruct the user to hang up, continue to hold, or leave a message for the user of the called party device.

Event services provided between domains include receiving a first subscription request to receive an event state of an event source. A view associated with the first subscription request is determined. A notify message is sent that reflects a first defined view into the event state of the event source that corresponds to the first subscription request. A second subscription request is received to receive the event state of the event source. A view associated with the second subscription request is determined. It is determined if the first defined view corresponds to the second subscription request.

A system and method for handling network overload includes receiving one or more requests, wherein an originating client originates the one or more requests. It is determined if a network element handling the one or more requests is overloaded. If the network element is overloaded, a pushback message associated with a specific request of the one or more requests is generated. The pushback message is sent to the originating client.

A system and method for handling network overload includes receiving one or more requests, wherein an originating client originates 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.

Methods, systems, and computer readable media for regulating pinhole preservation traffic generated or received by firewall or network address translator (NAT) session initiation protocol (SIP) user agent clients (UACs) are disclosed. One method includes, maintaining a list of contact information for a plurality of SIP UACs registering from behind at least one of a firewall and a NAT. The method further includes iterating through the list to generate SIP messages to the different UACs such that the SIP messages to the different UACs are spaced at substantially regular intervals with respect to each other, wherein the SIP messages to the different UACs trigger responses from the UACs such that the responses are spaced at substantially regular intervals with respect each other.

The subject matter described herein relates to methods, systems, and computer readable media for generating and using statelessly reversible representations of SIP information by SIP cluster entities. One method includes, at a first SIP cluster entity, receiving a first SIP message including SIP information. The method further includes generating a second SIP message including a statelessly reversible representation of the SIP information. The method further includes transmitting, to a SIP entity that is not a member of the cluster to which the first SIP entity belongs, the second SIP message with the statelessly reversible representation and information for reaching the cluster.
