Abstract: Methods and systems for determining call types are described herein. An intelligent node is configured to determine whether a call is a mobile-to-mobile call between subscribers of a telecommunication service provider based on a response to a request from the intelligent node. The intelligent node may further be configured to send a state request to an interconnecting network of the telecommunication service provider. A node of the interconnecting network determines whether a serving subscriber identifier is included in a routing database of that node. If the identifier is not included, the node responds with an error message. If the identifier is included, the node communicates with a relay function and responds to the request with a state received from the relay function. The intelligent node may also be configured to send an ENUM query and receive an identifier of the telecommunication service provider associated with the serving subscriber.

Abstract: The present invention discloses a simple low cost framework for robust operational control of video encoders. The framework comprises a two-layer architecture that effectively decouples the processes of video bit rate control and video quality/distortion control. The upper layer includes a video bit rate controller that operates on a single picture/picture-slice, or a set of pictures/picture-slices, and is based on feedback control techniques used in automatic control systems. The lower layer includes a video quality/distortion controller that operates at the level of blocks of pixels, and reduces distortion artifacts. The decoupled nature of the encoder control architecture of the present invention provides the flexibility of combining various feedback control algorithms and various distortion reduction schemes.
