Unified authentication method for application in trunking system, server and terminal

A unified authentication method for application in a trunking system, comprising:

• transmitting, by a terminal, a registration request to an application service network element of a server, wherein the registration request carries a token indicating a unique identity of a user initiating the registration request and an identification, enabling the application service network element of the server to perform a registration to the terminal according to the identification and transmit the token to an authorization authentication network element of the server which performs a token authorization to the user according to the token, and the token is assigned by the authorization authentication network element of the server to the user when the user logs onto the terminal;
• and
• performing, by the terminal, an application service interaction with the application service network element of the server if the token authorization is passed.

A terminal, comprising:

• a transmitting module, configured to transmit a registration request to an application service network element of a server, wherein the registration request carries a token indicating a unique identity of a user initiating the registration request and an identification, enabling the application service network element of the server to perform a registration to the terminal according to the identification and transmit the token to an authorization authentication network element of the server which performs a token authorization to the user according to the token, and the token is assigned by the authorization authentication network element of the server to the user when the user logs onto the terminal;
• and
• an interacting module, configured to perform an application service interaction with the application service network element of the application server if the token authorization is passed.
