Abstract
Abstract In a communication system, a link protocol for a transparent data between a mobile station and a base station is selected by pre-selecting from all possible combinations of available link protocols a set of pre-selected combinations of link protocols based on a predefined service requirement and at least one basic capability of the mobile or base stations. Then, the link protocol is selected from the pre-selected combinations of link protocols based on measurements of one or more link quality parameters and at least one variable restriction caused by instantaneous conditions in the communication system.
