Cross-binding control method and device for dual-SIM mobile phone

Abstract

The invention relates to a dual-SIM mobile phone cross binding control method. The method comprises steps: cross binding is carried out and whether cross binding fails is monitored; when cross binding is monitored to fail, the cross binding state is updated, and a cross binding ending instruction is sent to a RIL (radio interface layer); and the RIL receives the cross binding ending instruction, and the RIL state is updated to be a normal state. When cross binding is monitored to fail, the cross binding ending instruction is sent to the RIL to enable the state to be updated to be the normal state, the RIL can give an order to activate an SIM, and thus, normal network registration of the SIM can be realized without restarting the mobile phone after cross binding fails. The invention also provides a dual-SIM mobile phone cross binding control device.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a method and device for controlling cross-binding of a dual-card mobile phone. Background technique [0002] In a single-antenna, multi-mode dual-card mobile phone, not both cards can perform the same business. The corresponding card on the main stack has the strongest function, and the function of the card on the secondary stack is relatively weak. Sometimes it is necessary to bind the cards on the secondary stack to the main stack to perform the required business. The protocol stack and the card slot are bound to each other, and the unbinding and binding between the corresponding protocol stack and the card slot is mainly completed through cross-binding. The card needs to be disabled during the cross-binding, but the cross-binding Errors may occur during the process, resulting in an error in the state of the RIL (radio interface layer, radio interface layer), making the...

Problems solved by technology

The protocol stack and the card slot are bound to each other, and the unbinding and binding between the corresponding protocol stack and the card slot is mainly completed through cross-binding. The card needs to be disabled during the cross-binding, but the cross-binding There may be errors in the process, resulting in RIL (radio interface layer, radio interface layer) state errors, making RIL in an abnormal state

If the RIL is in an abnormal state, the RIL will not order to activate the card, which will cause the card to be unable to be re-activated, which will also cause the card to fail to log into the network normally.

Even if the card is hot-swapped, the state of RIL cannot be restored to normal. Only by restarting the mobile phone can the card be injected into the network normally.
