Abstract: Embodiments relate to a communication system comprising a call handler arranged to process channel signalling received from a communication network; a workload controller comprising means to determine the workload of at least one processing resource of the communication system; wherein the call handler comprises means to block establishment of at least one channel in response to the workload of the at least one processing resource.

Abstract: A voice markup language for a service for a telecommunication service platform, the telecommunication service platform having a communication layer and a session layer, the language comprising an application transfer tag, the application transfer tag comprising an identifier corresponding to a further service provided on the telecommunication service platform, wherein the application transfer tag causes the session layer to cause a call connected to the service to be processed by the further service.

Abstract: To provide a specialized resource function within the telephone network, server apparatus is described having a first interface for communication with a signalling network of a telephone network and a second interface for communication with a media gateway that has at least one bearer channel to the telephone network. The apparatus has a control arrangement for enabling the apparatus to provide, through the second interface, a document, such as a VoiceXML document, for rendering by the media gateway, the document being provided at least partly under the control of information received from a service control subsystem of the telephone network in an interaction through the first interface. An associated media gateway and method are also described.

Abstract: Methods, systems, and devices are provided for a media platform. One method includes receiving DMA requests for connecting media data traffic to DMA slots of a DMA memory module. Available DMA slots are determined from a pool of available DMA slots and allocated for media data traffic. DMA slots are released to the pool of available DMA slots when a DMA slot is no longer being used. The method further includes using a TMC proxy to connect media data traffic between the DMA memory module and a DSP software module based on assigned DMA slots.

Abstract: An exchange node operable to establish a backward connection comprising part of a call session, the exchange node being operable, on the occurrence of a fault in a backward direction of the exchange to transmit a pivot request to a pivot node in a backward direction of the fault, the pivot request comprising a redirection request, a call identifier, and instructions to establish a return connection between the pivot node and a nominated node.

Abstract: A computer system is provided with an operating system that has a streams mechanism for providing streams between user-space processes and drivers. This mechanism permits a user-space process to set up a multiplexer driver for multiplexing and demultiplexing streams. To facilitate the dynamic allocation of new streams to the multiplexer driver, a stream server is associated with the multiplexer driver, the stream server keeping a pool of available streams from which it satisfies any requests for more streams made by the multiplexer driver. The stream server can request a special user-space process to supply new streams to top up the pool.
