Abstract:
El objeto reivindicado se refiere a sistema y métodos para autorizar servicios. Un método incluye recibir un conjunto de datos relacionados con la pre-autorizacion de calidad de servicio (QoS) y procesar condicionalmente solicitudes de configuraciones de QoS subsiguientes basados al menos en parte en la informacion de pre-autorizacion. Dependiendo de la informacion de pre-autorizacion que corresponde a la solicitud de configuracion de QoS, la solicitud puede ser concedida, denegada o resultar en enviar una solicitud para la autorizacion.
Abstract:
Methods and apparatus related to message compression/decompression are described. A compressed message is generated by indicating what changes are to be made to a previous message to produce the message sought to be transmitted. The required change, in the form of at least one command and corresponding parameter, is transmitted as a compressed version of the message being communicated. This approach takes advantage of the fact that messages sent over time often include much of the same message content and only one or a few fields may have changed. The techniques are general and involve including a command in the compressed message along with at least one parameter. The command indicates processing to be performed on a previous message to generate the uncompressed message. The parameter may be, e.g., data to be inserted into the previous message or specify a location in the previous message where the change is to be made.
Abstract:
Methods and apparatus for compressing messages used to support mobile communications are described. After transmission of a first mobile IP message which may be a conventional mobile IP message, a compressed mobile IP message is transmitted. The compressed message includes a new "compressed message" indicator and information which is to replace information in the previous message or to be added to the previous message to construct a new message. In some embodiments, the compressed message includes a mask field, e.g., a sequence of bits, each bit corresponding to one field of a standard registration request message or binding update message. If the mask flag bit corresponding to a field is set, it indicates that the compressed message includes information to replace the content in the corresponding field of the previous message or to be added to the previous message as a field corresponding to the asserted bit.
