A communication apparatus is provided, which is capable of selecting the communication rate at high speeds with increased reliability along with a communication rate selecting method for use therein. An TCH number in this station detecting means 21 is provided for detecting a number of TCH to be assigned by a base station. An detected TCH number notify control means 22 is operatively responsive to receipt of the TCH number as detected by the TCH number in this station detecting means 21 for notifying it to a connected station under communication. An TCH number in connected station detecting means 23 is operable to monitor a received signal from the communication with connected station for detection of a TCH number as presently assigned thereto by the base station. A communication rate request/instruction reception means 24 is for receiving a communication rate switching request from a user via a key input unit 30 . A communication rate switching control means 25 performs a communication rate switching control operation in accordance with the TCH number detected by the TCH number in this station detecting means 21 and the TCH number detected by the TCH number in connected station detecting means 23 as well as the communication rate switching request from the user.
