Abstract
A system for configuring signaling messages in a telecommunications system when setting up the data transmission rates on the forward and reverse links for data transmission on a variable rate symmetric/asymmetric data channel, so as to shorten the time and signal length required in the connection setup of such a system and to reduce the demand on processing resources and processing time in both the mobile and the base stations. An information record contained in a signaling message, such as a Service Request Message, a Service Response Message, a Service Connect, or a Status Response Message, that is used to to setup the forward and reverse links of the data channel, is provided with an ASYMMETRIC.sub.-- RATES bit field. In the case when both forward and reverse links are indicated in a service type message to use the same rate configuration, i.e., the same link setup parameters, the ASYMMETRIC.sub.-- RATES bit, i.e., the bit in the ASYMMETRIC.sub.-- RATES field in the signaling message, is set to one binary value, e.g., `0`, to indicate that the same rate configuration is used for both directions. Then only one rate configuration is encoded in the service type message and the mes…
