Abstract

The invention discloses a non-access stratum digest authentication method in a trunking communication system, comprising: UE sends a trunking registration request message to a target T-CN, the message carries login authentication indication information and a first Inquiry parameter value, so that the target T-CN feeds back the cluster registration acceptance message to the UE based on the login authentication indication information; the UE authenticates the target T-CN based on the first response parameter value for authenticating the network carried in the cluster registration acceptance message. -CN; if the authentication is successful, the UE obtains the second response parameter value for authenticating the UE based on the second challenge parameter value carried in the cluster registration acceptance message for inquiring the UE; the UE sends the cluster to the target T-CN A registration complete message, which carries a second response parameter value, so that the target T-CN authenticates the UE based on the second response parameter value, and implements non-access stratum digest authentication. The invention can realize two-way authentication between UE and T-CN.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a non-access stratum digest authentication method in a cluster communication system. Background technique [0002] The trunking communication system is a dedicated wireless communication system developed to meet the command and dispatch needs of industry users and is oriented to specific industry applications. In the trunking communication system, a large number of wireless users share a small number of wireless channels, and the command and dispatch business is the main application. It is a multi-purpose, high-efficiency wireless communication system that utilizes frequency resources. The trunking communication system has a wide range of application markets in the fields of government departments, public safety, emergency communications, electric power, civil aviation, petrochemical and military. LTE (Long Term Evolution, long-term evolution) broadband multimedia trunking...
