Abstract

The invention provides a data service transmission method and a mobile communication device. The mobile communication device includes a first modulation-demodulation module, a second modulation-demodulation module and a radio frequency link module. The data service transmission method includes: when the mobile communication device is at a roaming place, service transmission under a first communication network is stopped; the second modulation-demodulation module acquires card information of a user ID card in a third communication network at the roaming place through a radio frequency link in the radio frequency link module from a server; the first modulation-demodulation module receives an authentication request from the third communication network through the radio frequency link and sends the authentication request to the second modulation-demodulation module; the second modulation-demodulation module communicates with the server through the radio frequency link to acquire authentication information and sends the authentication information to the first modulation-demodulation module; the first modulation-demodulation module sends the authentication information to the third communication network through the radio frequency link and performs 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...
