Abstract

Se proporcionan métodos para que un equipo de usuario, UE, (10) en NR RRC para regresar a un contexto de seguridad antiguo si falla un procedimiento de Reanudación de RRC desde un estado inactivo. De esta manera, cualquier intento de Reanudación posterior por parte del UE (10) derivará en nuevas claves de seguridad a partir de las claves antiguas, lo que significa que las claves y el contexto de seguridad serán los mismos para cada intento. De esta manera, el contexto de seguridad en el UE (10) permanecerá sincronizado con el contexto de seguridad de la red, independientemente de cuántos intentos haya llevado a cabo el UE (10) (asumiendo que la red no cambie el contexto de seguridad cuando falle el procedimiento de Reanudación). Como alternativa, el UE (10) puede almacenar el nuevo contexto de seguridad que deriva durante el primer intento de Reanudación, y luego asegurarse de que se vuelva a usar en intentos de Reanudación posteriores.
