Various embodiments implemented on a mobile communication device leverage the availability of multiple RATs to receive service from a combination of RATs that avoids the potential for inter-RAT coexistence interference. A mobile communication device processor may determine whether there is a likelihood of inter-RAT coexistence interference between a first RAT and a second RAT. In response to determining that there is a likelihood of interference occurring between the first RAT and the second RAT, the device processor may attempt to receive service with the first RAT and a third RAT that will not interfere with the first RAT. The device processor may monitor conditions to recognize when the likelihood of interference no longer exists between the first RAT and the second RAT, and reestablish service with the second RAT when that happens. Thus, the device processor may ensure that service is only acquired with non-interfering RATs.

Avoidance of interference during simultaneous multi-active technologies in global mode

Methods, devices, and systems embodiments enable management of service preemption of at least one of a plurality of subscriptions that utilize a plurality of radio-frequency (RF) chains on a multi-Subscriber-Identity-Module, multi-active communication device in a manner that can accommodate a variety of different RF hardware components and configurations. Various embodiments provide methods implemented by a processor to manage service preemption. In response to detecting that a service of a second subscription initiated on a first RF chain is or will preempt a service of a first subscription that is also serviced by the first RF chain, the processor may determine whether there is a similar service on a second RF chain that may be used as a substitute for the first subscription's preempted service and, when available, the processor may configure the first subscription to begin utilizing the substitute service until the first RF chain is available.
