Abstract

La présente invention concerne un procédé et un appareil de transmission de messages système, un procédé et un appareil de réception, ainsi qu'un terminal. Le procédé de transmission comprend les étapes consistant à : diviser à l'avance un message système en un bloc d'informations principal (MIB), des informations système (SI) minimales restantes et des SI autres, le MIB comprenant des informations d'indication de diffusion indiquant quels blocs d'informations système (SIB) dans les SI autres doivent être diffusés, et les SI minimales restantes comprenant des informations de planification concernant la diffusion de SIB dans les SI autres; et diffuser un SIB correspondant dans les SI autres sur un troisième canal de diffusion en fonction des informations d'indication de diffusion et des informations de planification. Dans la solution technique de la présente invention, les informations de planification concernant les blocs d'informations dans les SI autres sont relativement stables, ce qui permet de garantir que les contenus des SI minimales restantes sont relativement stables, et facilite ainsi la transmission des SI minimales restantes.
