Abstract: A gain obtaining method for a non traffic card of a multi-card multi-standby communication device, comprising: acquiring spare time information of a traffic card (S101); monitoring a cell broadcast channel of a non traffic card in a spare time of the traffic card, to measure a current signal intensity of a cell (S102); and calculating a signal gain required by the non traffic card for correctly receiving data according to the signal intensity (S103). Based on the gain tracking method for a non-traffic card, a multi-card multi-standby communication device is further provided. Through the technical solutions, the traffic card can track the gain required by the non traffic card for correctly receiving data during the implementation of a service.

Abstract: A method for receiving paging information, including acquiring free time information of a traffic card and occupation time information for receiving paging information of a non-traffic card; and when occupation time for receiving paging information of the non-traffic card is not in conflict with free time of the traffic card, receiving paging information of the non-traffic card on the free time. Based on the above method, an apparatus for receiving paging information is provided. Paging information of a non-traffic card can be received when the traffic card is in traffic, which helps identify if the non-traffic card has incoming service (i.e. incoming traffic).

Abstract: A method and an apparatus for synchronizing card without traffic in multi-card multi-standby mobile terminal are disclosed. The method includes: receiving, by a non-traffic card, a synchronization channel signal from an adjacent network cell according to frequency point of a synchronization channel of the adjacent network cell prestored in the non-traffic card, when a traffic card is in traffic; if the receiving of the synchronization channel signal from the adjacent network cell fails, performing, by the non-traffic card, a full-frequency network searching after the traffic of the traffic card, for receiving a synchronization channel signal from a network cell of the network cells and establishing synchronization with the network cell corresponding to the synchronization channel signal. The method and apparatus avoid communication failures caused by the out-of-synchronization of non-traffic card during the traffic (i.e. service) of the traffic card.

Abstract: The present invention provides a method of resolving reception conflicts for a multi-card multi-standby mobile terminal, which is for resolving the conflicts of the mobile terminal based on Global System for Mobile communication (GSM) network and in the standby mode, including: acquiring synchronization result with base stations and judging if there are time slot conflicts between multiple SIM cards of the multi-card multi-standby mobile terminal according to the synchronization result; if the conflicts being non-time slot conflicts, receiving and processing data of different SIM cards in different time slots of a TDMA frame; and if the conflicts being time slot conflicts, receiving and processing data of a non-current SIM card in redundant frames of BCCH or CCCH of a current SIM card.
