Method for the transmission of data of a plurality of connections having data rates that change during an established connection and corresponding station

摘要

The method involves each connection using the lower of 2 transmission rates more often than a higher rate, mutually orthogonal spreading codes and at least 2 encryption codes. The data for a connection are spread with an individual connection code and encrypted with a first code to determine a first rate for the connection. The data are divided into groups that are spread and encrypted with different codes to determine the second rate. The method involves each connection (V1,V2) using the lower of two possible transmission rates more often than a higher rate and using mutually orthogonal spreading codes and at least two encryption codes. The data for a connection are spread using an individual connection code and encrypted with a first code to determine a first transmission rate for the connection. The data are divided into groups (G11-G22) that are spread and to which different encryption codes are applied to determine the second rate. AN Independent claim is also included for the following: (a) a station for a communications system for transmitting data for several connections with varying transmission rates.
