CIPHERTEXT SENDING METHOD, CIPHERTEXT TRANSMISSION METHOD, MOBILE TERMINAL AND COMMUNICATION BASE STATION

摘要

The present invention relates to the field of communications. Disclosed are a ciphertext sending method, a ciphertext transmission method, a mobile terminal and a communication base station. The method comprises the following steps: acquiring a network standard of an accessed communication network; and sending a direct transmission command to the communication network before sending a ciphertext if the network standard is a CDMA standard.
