| 发明名称 | Protocol version negotiation method, mobile terminal, base station and communications system | ||
| 摘要 | 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. | ||

| 主权项 | 1. A protocol version negotiation method, comprising: receiving, by a mobile terminal, an air interface message sent by a base station according to a 3rd Generation Partnership Project protocol, wherein the air interface message comprises 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 a mobile terminal capability set; obtaining the highest protocol version supported by the base station according to the information element; determining whether the highest protocol version supported by the mobile terminal is later than the highest protocol version supported by the base station; 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, wherein the information element of the air interface message includes a number indicating the highest protocol version supported by the base station in one of a system message and a master information block system message. | ||
