Abstract

The invention discloses a non-access stratum abstract authentication method in a trunking communication system, the method comprises the following steps: UE sends a cluster registration request message to a target T-CN, the message carries a login authentication indicating information and a first interpellation parameter value for interpellating a network, and thus, the target T-CN is enabled to feed back a cluster registration accepting message to the UE based on the login authentication indicating information; the UE authenticates the target T-CN based on a first response parameter value which is used for authenticating the network and carried in the cluster registration accepting message; if authentication is successful, based on a second interpellation parameter value which is used forinterpellating the UE and carried in the cluster registration accepting message, the UE obtains a second response parameter value used for authenticating the UE; the UE sends a cluster registration completed message to the target T-CN, the message carries the second response parameter value, thus, the target T-CN is enabled to authenticate the UE based on the second response parameter value, andnon-access stratum abstract authentication is realized. The method provided by the invention can realize bidirectional authentication of 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...
