Multi-card and multi-mode terminal, method and device for synchronizing access modes thereof

Abstract

The invention discloses a multi-card and multi-mode terminal, a method and device for synchronizing access modes thereof. The method for synchronizing the access modes of the multi-card and multi-mode terminal comprises the following steps of: when a terminal card is triggered to be switched from a first cell in a first network mode to a second cell in a second network mode, controlling the triggered terminal card to be switched to the second cell and controlling other terminal cards to be in an interrupt state; and, after the triggered terminal card is successfully switched to the second cell, controlling other terminal cards to be switched to the second cell. According to the technical scheme of the invention, in the event of not increasing hardware equipment of the multi-card and multi-mode terminal, the multi-card and multi-mode terminal can be synchronously switched to the same access technology. A plurality of terminal cards can work in a network mode simultaneously, therefore, the investment of user equipment is saved; and modes of the multi-card and multi-mode terminal can be freely switched.

Description

technical field [0001] The invention relates to a mobile communication terminal, in particular to a multi-card multi-mode terminal and a method and device for synchronizing access modes thereof. Background technique [0002] In the second generation of mobile communication (2G) technology, Global System for Mobile Communications (GSM, Globe System of Mobile Communication), and its evolution system General Packet Radio System (GPRS, General Packet Radio System), Enhanced Data Rate GSM Service (EDGE , Enhanced Data rates for GSM service) is one of the most widely used mobile communication systems in the world. At present, with the gradual popularization of third-generation mobile communication (3G) technology, for example, 3G services based on Time Division-Synchronous Code Division Multiple Access (TD-SCDMA, Time Division-Synchronous Code Division Multiple Access) technology have been launched nationwide , more and more people start to use 3G mobile phones, but because the c...

Problems solved by technology

[0008] In addition, for a multi-card multi-mode terminal that only uses one set of communication modules (including radio frequency chips and baseband processing chips), if multiple terminal cards reside in different cells, the paging reception and neighboring cell The measurement can only be switched in a time-sharing manner, and the paging reception efficiency of multiple terminal cards residing in different cells is usually inversely proportional to the number of cards that are on standby at the same time. Decrease with the increase of the number of cards

[0009] In terms of power consumption, since each terminal card resides in a different cell, it needs to perform paging reception and neighbor cell measurement on different cells in turn in time-sharing, so the idle time of the terminal will be much less, and the corresponding power consumption will be reduced. consumption will be higher
