Abstract

La présente invention concerne l'optimisation de recherches de réseau sans fil cellulaire par un dispositif sans fil qui prend en charge de multiples modules d'identité d'abonné (SIM) et/ou SIM électroniques (eSIM). Le dispositif sans fil comprend au moins deux SIM/eSIM actifs, chaque SIM/eSIM étant associé à un modem distinct. Un premier modem effectue des recherches de PLMN et fournit des résultats de recherche de PLMN à un second modem, qui renonce à ou retarde ses propres recherches de PLMN. Des résultats de recherche de PLMN sont fournis dès qu'un PLMN est détecté par le premier modem, et le second modem peut attendre sur (ou resélectionner) un PLMN de priorité plus élevée/la plus élevée détecté et rapporté par le premier modem sans attendre des résultats de recherche de PLMN supplémentaires. Lorsqu'un premier modem du dispositif sans fil est dans un mode de service limité ou normal, le second modem ignore des messages de bloc d'informations système (SIB) pour des alertes d'urgence et repose sur le premier modem pour surveiller des messages SIB et fournir un accès à des services d'urgence.
