1. A method for resolving control channel transmission collision in a mobile device having first and second subscriptions (SUBs) when the first SUB is in an active voice call and the second SUB is in a held voice call, the method comprising:
determining, by the mobile device, whether a control channel transmission of the first SUB would collide with a control channel transmission of the second SUB; and alternating, by the mobile device, the first SUB control channel transmission and the second SUB control channel transmission to avoid collision, in response to determining the first SUB control channel transmission would collide with the second SUB control channel transmission, the method further comprising: when the determining indicates collision, determining, by the mobile device, whether the active call conditions are poor; when the determining of the active call conditions indicates the active call conditions are not poor, determining, by the mobile device, whether the held call conditions are poor; and when the determining of the held call conditions indicates the held call conditions are not poor, alternating, by the mobile device, first SUB control channel transmission and second SUB control channel transmission. |
