Abstract

Provided are a communication method and mobile communication device. The communication method is applied to a mobile communication device, wherein the mobile communication can execute service transmission in a circuit switching domain under a first communication network. The communication method includes the steps of: when the mobile communication device arrives at a roaming place, utilizing service transmission n the circuit switching domain under the first communication network to obtain user identity identification information associated with a second communication network of the roaming place; based on the received user identity identification information, registering on the second communication network; and executing service transmission in a circuit switching domain or packet switching domain under the second communication network.

Description

technical field [0001] The present invention relates to the technical field of communication, and more specifically, to a communication method and a mobile communication device. 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. Specifically, the user identity card (such as a SIM card) is bound with the home. If the terminal user continues to use the SIM card after leaving the place where the SIM card is currently used, additional roaming charges will be incurred. [0003] In order to save tariffs, end users may need to purchase roaming SIM cards to achieve localization of tariffs. SIM cards are also tied to a...
