Embodiment Construction

[0047] The embodiment of the present invention considers whether multiple terminal cards can reside in the same cell when the multi-card multi-standby terminal is turned on, that is, initiate cell synchronization of multiple terminal cards if possible, and try to allow multiple terminal cards to reside In the same cell, the terminal cards residing in the same cell can share cell information, such as system information, measurement results of neighboring cells, etc., and can receive paging messages of the multiple terminal cards at the same time.

[0048] The multi-card multi-standby terminal synchronization method in the embodiment of the present invention includes: after starting up, the first terminal card searches the network and resides in the first cell; controls the second terminal card to reside in the first cell, and the second The terminal card is a terminal card suitable for residing in the same cell as the first terminal card.

[0049] The first terminal card may be...

Abstract

The invention discloses a multi-card multi-standby terminal and a synchronization method and device thereof. The synchronization method of the multi-card multi-standby terminal comprises the steps: after starting up, a first terminal card searches a network and residues a first cell; and a second terminal card is controlled to residue in the first cell, and the second terminal card is a terminal card suitable for residing the same cell with the first terminal card. The technical scheme of the invention has the advantages of increasing paging receiving efficiency and neighbor measurement efficiency, reducing terminal power consumption, shortening cell residing time of the terminal cards, simplifying physical layer realization and the like.

Description

technical field [0001] The invention relates to a mobile communication terminal, in particular to a multi-card multi-standby terminal and its synchronization method and device. Background technique [0002] With the rapid development of communication technology, information exchange between people is also more frequent, a mobile communication terminal (such as mobile phone, vehicle mobile terminal, etc.) can no longer meet people's needs, especially those engaged in sales, management and other People, sometimes need two or three or more terminals to barely meet the needs. It is very inconvenient to carry so many terminals, therefore, multi-card terminals have appeared on the market. This kind of terminal allows the user to only need one carrier, but can install multiple terminal cards (SIM card or UIM card or USIM card), which is obviously much more convenient than carrying multiple terminals. [0003] If the user needs to use multiple numbers on one terminal, the followin...
