Abstract: A board includes: a baseband unit, multiple transmitters, multiple receivers, a multi-antenna array, a correction transceiver, a correction calculation unit, a bidirectional coupler, and a combiner-splitter. The bidirectional coupler is configured to couple radio frequency signals output by the multiple transmitters and then transmit the coupled radio frequency signals to the combiner-splitter, and to couple receiver correction reference signals obtained by performing division by the combiner-splitter and then send the coupled receiver correction reference signals to the multiple receivers; and the combiner-splitter is configured to combine transmitter radio frequency signals coupled by the bidirectional coupler and then transmit the combined transmitter radio frequency signals to the correction transceiver, and to divide a receiver correction reference signal sent by the correction transceiver and then send receiver correction reference signals obtained by performing division to the coupler. Accuracy of channel reciprocity correction of a transmitter and a receiver can be ensured.

Abstract: The present invention discloses a method and a relevant apparatus for achieving localized roaming of a mobile terminal. In the present invention, the mobile terminal sends real SIM card information to apply for a virtual SIM card to obtain a corresponding mobile terminal number of a roaming region, and registers user information to activate the virtual SIM card to serve as a calling party or a called party, so as to set up a called communication connection of a real SIM card. The mobile terminal applies for a virtual SIM card from a communication network of a roaming country to obtain a corresponding mobile terminal number of the roaming region through allocation, so that the user does not need to purchase a new SIM card in the roaming region, thereby saving the charges for purchasing the SIM card, ensuring a convenient operation and satisfying the demand of the user.
