摘要：
A method, device and system for updating a security algorithm of a mobile terminal are disclosed in the present invention. The method includes the steps of when a communication connection between a mobile terminal and a network side is established, transmitting a Device Management (DM) request message for obtaining state related information on a designated type to the mobile terminal; receiving the state related information on the designated type returned by the mobile terminal; and obtaining an algorithm identifier corresponding to the state related information and indicating the mobile terminal to update the security algorithm used locally according to the algorithm identifier. It is able to ensure the usage security of mobile terminals according to the present invention.
