Abstract

The invention relates to the field of wireless communication, and discloses a dual-mode dual-card dual-standby dual-pass wireless terminal and a communication method thereof. In the method, when a USIM card stays in a GSM cell, two cards perform time division multiplexing on a GSM radio frequency physical layer; when the USIM card stays in a WCDMA cell, the two cards use the GSM radio frequency physical layer and a WCDMA radio frequency physical layer respectively, so that dual-card dual-standby dual-pass can be realized with fewer radio frequency devices, including a GSM+GSM mode and a WCDMA+GSM mode, and one of the cards can realize dual-mode seamless switching between GSM and WCDMA. When the SIM card and the USIM card have paging channel conflict, one card performs cell reselection; and if the conflict still exists, the SIM card can be abandoned.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a dual-mode, dual-card, dual-standby, and dual-pass communication technology. Background technique [0002] With the rapid development of wireless communication, mobile phones have become an indispensable communication tool for people. People's demand for communication has also developed from simple voice communication to all-round services such as video, Internet access, and positioning. In order to adapt to the development of user needs, the communication system is also constantly evolving. At present, many countries have shifted from second-generation mobile communication systems such as Global System for Mobile communication (GSM for short) and Code Division Multiple Access (CDMA for short) to wideband CDMA The evolution of third-generation mobile communication systems such as Wideband Code Division Multiple Access (WCDMA for short) and Time Division Synchronous Code D...
