Another heater component has a mass of between about 0.1g and about 1g. A further heater component comprises an alloy comprising at least 99 wt % Iron. A yet further heater component comprises carbon steel. A still further heater component defines a longitudinal axis and has a wall thickness, measured in a direction perpendicular to the longitudinal axis, of between about 0.025 mm and about 2 mm.

Abstract: An aerosol provision device includes at least one inductor coil for generating a varying magnetic field and a susceptor assembly arranged to receive aerosol generating material. The susceptor assembly is heatable by penetration with the varying magnetic field and includes a first portion defining an opening at one end of the susceptor assembly, where the opening has a first internal cross section. The susceptor assembly further includes a second portion adjacent to the first portion. The second portion has a second internal cross section that is less than the first internal cross section.

Abstract: A system and method for maintaining resiliency of subscriptions to an event server includes receiving a subscription request to establish a subscription to receive event state information of an event source, a primary event server providing the event state information. The event state information is received from the primary event server in accordance with the subscription request. The primary event server provides the event state information to an event consumer. It is determined whether the primary event server fails during the subscription.

Abstract: 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.

Abstract: 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.

Abstract: 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.

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.

Abstract: A system and method for optimizing inter-domain event services includes 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.

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.
