摘要:
The present invention discloses a method and system for implementing short message encryption. Both the Mobile Station (MS) and the Mobile Switching Center (MSC) are configured with encryption-decryption modules (1), which can encrypt and decrypt the short message by using the Cipher Key (CK) as the encryption-decryption factor. The CK is variable with the Random value (RAND). The CK is not shared between the receiving end and the sending end in the whole process, so that the encrypted short message has a high confidentiality. In addition, the security of the whole transmission environment can be realized by the selectable configuration.

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.

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.

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.

Disclosed in the present invention are an access method for performing a video call and a video call apparatus, wherein the method comprises the steps of: presetting an access password for a video call; after answering the video call, closing audio and video channels, and transmitting a command to a calling terminal for providing an access password for the video call so as to prompt said calling terminal to input an access password associated with the video call; determining if the access password associated with the video call and inputted by said calling terminal matches the preset access password; if so, performing the video call, and if not, refusing said calling terminal's request to perform the video call. According to the technical solution provided by the present invention, the function of automatically selecting whether to answer the video call according to the other party's identity is enabled.

Disclosed in the present invention is a method for transmitting prompt information and a terminal, which method comprises: a first terminal and a second terminal establishing communication; the first terminal acquiring a language type currently used by the second terminal; and the first terminal selecting a corresponding prompt information according to the language type and transmitting the prompt information to the second terminal. By virtue of the present invention, a corresponding prompt information can be selected according to the language type of a peer to prompt the peer during communications such as videophone and so on, which greatly improves the availability of the terminal and the user experience.
