Abstract

Divers aspects de la présente divulgation portent d'une manière générale sur la communication sans fil. Selon certains aspects, un équipement utilisateur (UE) peut initier un premier service associé à un premier module d'identité d'abonné (SIM) de l'UE et à une première priorité. L'UE peut initier un second service associé à un second SIM de l'UE et à une seconde priorité. L'UE peut commuter la première priorité et la seconde priorité pendant au moins une partie du premier service ou du second service. L'UE peut assurer une communication en fonction d'au moins une de la première priorité et la seconde priorité. La divulgation porte sur de nombreux autres aspects.
