Abstract
The present invention discloses a protocol version negotiation method, a mobile terminal and a base station. The method includes: receiving, by a mobile terminal, an air interface message sent by a base station according to a 3GPP protocol, where the air interface message includes an information element for indicating a highest protocol version supported by the base station, and the air interface message is sent before the base station sends a request message for querying the mobile terminal capability set; obtaining the highest protocol version supported by the base station according to the information element; and if the highest protocol version supported by the mobile terminal is later than the highest protocol version supported by the base station, configuring, by the mobile terminal, a protocol version used by the mobile terminal to a protocol version same as the highest protocol version supported by the base station.
