Abstract

L'invention concerne un procédé, un appareil et un système de transmission de message de système. Le procédé selon les modes de réalisation de la présente invention comprend les étapes suivantes : une station de base envoie un premier message de système à un dispositif terminal grâce à un canal de diffusion, le premier message de système comprenant un paramètre de réception d'un deuxième message de système et des informations d'indication, les informations d'indication étant utilisées pour indiquer si le premier message de système comprend ou non un paramètre de transmission de liaison montante ; la station de base envoie le deuxième message de système au dispositif terminal selon le paramètre de réception du deuxième message de système. Les modes de réalisation de la présente invention résolvent le problème de retard et de temps système importants de transmission de liaison montante effectuée par un dispositif terminal parce que le dispositif terminal peut effectuer la transmission de liaison montante uniquement lors de la réception d'un message minimal restant dans le cas où l'approche de segmentation dans un système LTE associé est appliquée à une nouvelle génération de système de communication mobile, et résout également le problème de mauvaises commodité et flexibilité de l'envoi de messages de système parce que l'approche de segmentation dans le système LTE est fixe.
