Abstract
A bit rate indicator for use in the mobile station of a radiotelephone system which provides an indication to the user of the maximal bit rate available in the current cell and the predicted bit rate the user can expect to achieve if a session were initiated in his present location. In calculating the maximal bit rate, the mobile station receives a message from the base station indicating the base station's capabilities, such as support for multi-slot operations and coding/modulation schemes. The mobile station then uses the base station's capabilities along with its own capabilities to determine the maximal bit rate. In calculating predicted bit rate, the mobile station measures the link quality of at least one channel and based on, at least one of, the measured link quality and mobile's capabilities, determines a predicted bit rate the user would achieve in his present location. Both the maximal and predicted bit rates can be outputted on the mobile station for comparison by the user. This information can be used to effectively direct the user to the location in a cell with the best link quality. The present invention may be especially useful when using a mobile station to interface with the Internet.
