Multi-SIM Standby Gain Tracking During Traffic Card Idle Slots
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-SIM multi-standby communication devices, non-traffic cards cannot obtain the necessary signal gain to receive data correctly due to their inability to monitor a cell's broadcast channel and measure signal intensity when a traffic card is conducting a service.
Innovation Solution
A method and device that involve obtaining information about the idle time period of a traffic card, monitoring the cell's broadcast channel associated with a non-traffic card during this idle time to measure current signal intensity, and calculating the signal gain needed for correct data reception.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single communication module is used for multi-SIM multi-standby, then device complexity and power consumption are reduced, but non-traffic cards cannot obtain signal gain to receive data correctly when traffic card is conducting service
Solution Approach 1:
The patent applies preliminary action by having non-traffic cards monitor broadcast channels and measure signal intensity in advance during the traffic card's idle periods. This allows the system to pre-calculate the necessary signal gain for non-traffic cards before they need to receive data, ensuring reliable reception without requiring additional communication modules.
2Adaptability or versatility
If multiple communication systems are used for multi-SIM multi-standby, then each SIM card can be in standby or communicating state simultaneously, but additional cost and power consumption increase
Solution Approach 1:
The patent merges multiple SIM card operations into a single communication module. By allowing non-traffic cards to monitor broadcast channels during traffic card idle periods and pre-calculating signal gain, the system achieves multi-SIM multi-standby functionality with simultaneous communication capability while using only one communication module, thereby reducing power consumption compared to having separate communication systems for each SIM card.
3Reliability
If non-traffic card monitors broadcast channel during traffic card service, then signal gain can be obtained for correct data reception, but time slot conflicts occur
Solution Approach 1:
The patent applies periodic action by having non-traffic cards monitor broadcast channels during the traffic card's periodic idle periods. Since GSM systems operate in structured time slots with regular idle periods for traffic cards, the patent utilizes these periodic opportunities to gather signal intensity data and calculate gain, ensuring both reliable data reception preparation and proper time slot management without conflicts.

AI summary
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.
