Abstract: A communication device for providing dual-active personae using a single subscriber identification module. A long term evolution (LTE) protocol stack, maintained in the memory, defines a layered data structure for transmitting and receiving data. A single subscriber identification module provides data for a first persona and a second persona. A processor is coupled to the single subscriber identification module and memory and implements, on the single communication device, first virtual user equipment (vUE) associated with the first persona and second vUE associated with the second persona using virtual LTE protocol stacks for each vUE supported by the single subscriber identification module.

Abstract: A multiple-persona system and method is described, wherein a UE (user equipment) is able to connect to two different networks simultaneously. In a multiple-persona system, one of the personas may have a higher significance than the other persona. For example, a connection to a work network may be prioritized over connection to a home network. In such a situation, it may be desirable to have applications running on the work network have priority over applications running on the home network. Such a method and system may operate independently of the eNodeB or have the eNodeB actively controlling the priority among the personas. The scheduler in either the eNodeB or the UE may contain anew input for the significance of the persona. The significance of the persona is taken into account when sending data to and from the UE.
