Provided in the embodiments of the disclosure are methods and apparatuses for parameter configuration, a network device, and a terminal. The method includes that: a first base station receives first indication information and/or first configuration information from a terminal in a connected state. The first indication information indicates the terminal uses or supports an extended Discontinuous Reception (eDRX) operation in an inactive state, and the first configuration information includes an eDRX configuration parameter configured by the terminal; and the first base station configures a first eDRX configuration parameter for the terminal based on the first indication information and/or the first configuration information, the first eDRX configuration parameter is an eDRX configuration parameter corresponding to the inactive state.
