A method for pre-accessing a conference telephone is disclosed in the present invention. The method includes that: a network side detects a received call whose target is a main control party after the main control party initiates an encryption conference telephone; the call is not accessed if the call is a non-encryption conversation; the call is allowed to be accessed if the call is an encryption conversation. A system for pre-accessing a conference telephone is also disclosed in the present invention, wherein, the system includes a pre-accessing processing unit and a call type detection unit of the network side. A network side device is also disclosed in the present invention. The present invention realizes the pre-accessing of the encryption conference telephone, thereby improving security of the encryption conversation as well as avoiding the problem that a user is frequently affected when performing the encryption conference telephone.

A method for implementing information exchange is disclosed in the present invention, and the method comprises: a calling user terminal sending information to be sent to a called user terminal by carrying the information in a user-to-user signaling (UUS) field of a call message; the called user terminal sorting out the information carried in the UUS field from the call message after receiving the call message, and feeding back a message other than an acknowledge message to the calling user terminal; the calling user terminal terminating this call after receiving the message fed back by the called user terminal. The simplicity and the easy transformation of the software update of user terminals are fully utilized in the present invention; therefore the present invention can enable a user terminal to have the information exchange function only by properly modifying the software of the user terminal.

The present invention discloses a method for clear session and scrambled session communication switch between mobile terminals comprising: a first terminal initiating a scrambled session switch control request to a second terminal, and the second terminal returning a scrambled session switch control response after receiving the scrambled session switch control request; and the first terminal initiating a key negotiation process with the second terminal after receiving the scrambled session switch control response returned by the second terminal, and then transferring to scrambled session communication or suspending the scrambled session communication with the second terminal; wherein the scrambled session switch control request includes a scrambled session request or a clear session request. The present invention further provides a system for clear session and scrambled session communication switch between mobile terminals comprising a scrambled session switch control module and an encryption module set in a mobile terminal. The present invention protects end-to-end security in the communication process of the mobile terminals effectively.

The present invention provides a method and system for verifying a user alias. The method comprises: a calling terminal inserting a set alias and a calling user's own number into calling information when calling a called terminal; after the called terminal receives the calling information, when the calling terminal registers calling number display restriction or when the calling terminal cancels the calling number display restriction and the calling number of the calling is inconsistent with a calling user number stored locally in the called terminal, determining whether the calling user's own number matches successfully with the calling user number stored locally in the called terminal to display in different modes when the matching is successful and unsuccessful, respectively.
