Method for improving access success rate of multi-card and multi-standby mobile terminal and mobile terminal

Abstract

The invention discloses a method for improving the access success rate of a multi-card and multi-standby mobile terminal and the mobile terminal. A conflict cell list between standbys is arranged in the multi-card and multi-standby mobile terminal, and when a first user identification card in the multi-card and multi-standby mobile terminal executes frequency band searching, frequency points conflicting with current residing cells of the other user identification cards in the multi-card and multi-standby mobile terminal in the frequency band searching result of the first user identification card are filtered according to the conflict cell list between the standbys. According to the method and the multi-card and multi-standby mobile terminal, when a certain user identification card executes cell reselection or cell selection, the user identification card is made not to try to conflict with the current residing cells of the other user identification cards, the cell reselection or cell selection process can be effectively shortened, the call completion ratio can be effectively improved, the number of network failure is reduced, power consumption of mobile equipment is reduced, and thus normal operation of service communication is guaranteed, and work performance of the multi-card and multi-standby mobile terminal can be more stable and reliable.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method for improving the access success rate of a multi-card multi-standby mobile terminal and a mobile terminal. Background technique [0002] With the development of mobile devices, mobile communication has a greater impact on people's work and life. At the same time, people have higher and higher requirements for communication devices. In order to meet such needs, dual-card dual-standby mobile communication devices have emerged. Multi-card multi-standby mobile terminals, such as dual-card dual-standby on a single chip and single antenna, are an important cost reduction solution. For example, in a single-chip single-antenna dual-card dual-standby communication system, the mobile device needs to receive the Broadcast Control Channel (BCH) information of two Subscriber Identification Module Cards (SIM) within a specified period And paging channel (Paging Channel, ...

AI Technical Summary

Problems solved by technology

It is conceivable that multiple subscriber identification cards, such as two subscriber identification cards, have a relatively high probability of conflict when receiving BCH information and PCH information. As a result, the BCH information of a certain subscriber identification card cannot be fully received within the specified time or a downlink occurs. The possibility of failure is greatly increased

In addition, the wireless environment is affected by various uncertain factors such as various interferences and terrains, which leads to the frequent execution of cell reselection or cell selection process by mobile devices, which leads to a decrease in the call pass rate of mobile communication devices, frequent network disconnections, and power failures. Excessive consumption and various unfavorable conditions affect the stability of mobile devices
