Document Type and Number:
Japanese Patent JP3505150
Kind Code:
B2
Abstract:
According to the invention, a service-specific static rate adaptation factor that controls a service-specific quality of service is determined in a manner already known per se. A dynamic rate-oriented rate adaptation factor is determined for a link, whereby said factor adapts the hypothetical volume of data to a volume of data that is available in the next frame while taking into account the adaptation of the service-specific data rate that is yet to be performed. It is possible to pass through several optimization loops if said data volume is not rigidly predetermined as a result of a sufficient number of transmission channels and spread factors. A service-specific rate adaptation factor is determined by combining the static rate adaptation factor and the dynamic link-oriented rate adaptation factor, whereupon one single and therefore one-step adaptation of the data rate is carried out. Service data is thus compressed or expanded only once with said service-specific rate adaptation factors and inputted into a frame for transmission. The method is suitable for CDMA transmission methods within a UMTS.
