Abstract
Disclosed are a method and device for determining a security algorithm, and a computer storage medium. The method comprises: a first base station configures an RAN notification area for a terminal, wherein all base stations in the RAN notification area at least support a first security algorithm; the first base station configures the terminal for the first security algorithm.
Claims4
A method for determining a security algorithm, comprising:
- determining, by a base station, whether the base station supports a security algorithm of a terminal;
- and
- if the base station does not support the security algorithm of the terminal, sending a radio resource control (RRC) connection establishment message to the terminal in order for the terminal to reestablish an RRC connection.
A device for determining a security algorithm, comprising a processor, a memory for storing instructions, and a transmission apparatus for communication functions,
- wherein the processor is configured to execute the instructions in the memory to:
- determine whether a base station supports a security algorithm of a terminal;
- and
- send a radio resource control (RRC) connection establishment message to the terminal if the base station does not support the security algorithm of the terminal, in order for the terminal to reestablish an RRC connection.
