There are only 4 modes PS Mode 1, PS Mode 2, PS/CS Mode 1, PS/CS Mode = 2. These modes only specify, what type of attach is required (a IMSI, = EPS or a combined). Also if UE supports CSFB, it should be in CS/PS = modes . There is also +VCMOD which can be used to decide whether to use = CS or PS for voice calls. What does the Register interface do w.r.t ofono? What AT commands could = be used here to signal the UE mode of operation to modem? How does "voice" or "messaging" relate to the 4 modes specified in = 27.007 and 24.301?
