Abstract: Embodiments of the present invention provide a method and a device for associating a user with a group. The method includes: receiving, by a first communications device, a first association request sent by a second communications device, where the first association request includes an identifier of an MCPTT user and identifiers of N MCPTT groups, and N is a positive integer; associating the MCPTT user with M MCPTT groups of the N MCPTT groups according to association subscription information of the MCPTT user; and sending a first association response to the second communications device, where the first association response is used to indicate that the MCPTT user is successfully associated with the M MCPTT groups of the N MCPTT groups, 1≤M≤N, and M is an integer. In this way, the MCPTT user is associated with the M MCPTT groups that the MCPTT user is interested in.

Abstract: A method, a terminal and a communication system are provided for generating a local interface key. In the disclosure, the terminal generates a variable parameter and sends the generated variable parameter and other parameters for generating the local interface key to a network. The network derives, according to the variable parameter and the parameters for generating the local interface key, the local interface key. The terminal obtains the local interface key from the network so as to use in intercommunication with other device, such as a UICC, or other terminal device. Thus, the security of the intercommunication between the terminal and the other device is ensured.
