A user mode control method and system based on iris recognition for mobile terminal are provided. When the mobile terminal receives an operation instruction of a user to start a display screen, iris feature data of the current user are scanned. The iris feature data of the current user are matched with iris feature data of users collected in advance, and the corresponding user mode is started when the match succeeds. The user mode control method and system prevents a stranger from accessing private data, and greatly improves security of the user data.

A method for automatically switching subscriber mode through identifying IMSI includes, when a cell phone is turned on, determining if a first IMSI is consistent with a pre-stored second IMSI. If the first IMSI is determined to be consistent with the second IMSI, the cell phone enters a subscriber mode corresponding to the second IMSI. If the first IMSI is determined to not be consistent with the second IMSI, the first IMSI is matched with a third IMSI of an IMSI list pre-stored in the cell phone; when the first IMSI is determined to be consistent with the third IMSI, the cell phone enters a subscriber mode corresponding to the third IMSI. Thereby, the cell phone quickly and efficiently completes identifying an IMSI and automatically switches subscriber mode.

A method for transmitting contact information during a call may include, in a call of a mobile terminal, extracting voice data of a subscriber. The method may also include determining if voice data is representative of a voice control command. If the voice data is representative of a voice control command, converting the voice control command to a corresponding Unicode code. The method may further include searching for contact information that the subscriber needs to transmit according to the Unicode code, and transmitting the found contact information to another party. The method may not affect the call of the subscriber during the information transmission process. The method may not require manual operations by the subscriber. As a result, associated operations may be very convenient.

The present invention discloses a method and an apparatus for eliminating frequency-domain interference signals, and relates to communication technologies. The method includes: multiplying a frequency-domain channel estimation value by a frequency-domain interference signal to obtain a frequency-domain received interference signal; and subtracting the frequency-domain received interference signal from the frequency-domain received signal to obtain the frequency-domain received signal free of interference. The apparatus includes a multiplying module and a subtracting module. A frequency-domain equalizer includes an interference signal obtaining module and an interference signal eliminating module. The technical solution provided herein eliminates interference signals in the frequency domain, and saves the calculation load in contrast with elimination of time-domain interference signals.
