Abstract

The invention provides a data service transmission method and mobile communication equipment. The mobile communication equipment comprises a first modulation-demodulation module, a second modulation-demodulation module, a third modulation-demodulation module and a radio frequency link module. The data service transmission method comprises the following steps: selecting one of the first modulation-demodulation module, the second modulation-demodulation module and the third modulation-demodulation module when a roaming zone is reached, thus executing data service transmission under a third communication network; acquiring the card information of a user identification card in the third communication network from a server by the second modulation-demodulation module by virtue of the radio frequency link; receiving an authentication request aiming at the card information by the selected modulation-demodulation module by virtue of the radio frequency link, and transmitting the authentication request to the second modulation-demodulation module; acquiring the authentication information by the second modulation-demodulation module by virtue of communication between the radio frequency link and the server, and transmitting the authentication information to the selected modulation-demodulation module; and transmitting the authentication information to a third communication network by the selected modulation-demodulation module by utilizing the radio frequency link, and executing the data service transmission under the third communication network.

Description

technical field [0001] The present application relates to the technical field of communication, and more specifically, to a data service transmission method and a mobile communication device adopting the data service transmission method. Background technique [0002] With the development of smart terminals and wireless network technologies, users expect to use the same terminal to access the Internet at different locations. Different locations may be covered by different communication networks, and correspondingly, end users may need to pay expensive roaming data service charges for data transmission, especially in the case of international roaming. [0003] In order to save tariffs, end users may need to purchase a roaming subscriber identification card, that is, a subscriber identification card. Subscriber ID cards are bound to operators. If the user wants to change the operator, the user needs to buy a calling card in the roaming area or go to the operator's business ha...
