Abstract

Sont divulgués un procédé d'ajout de nœud, un talkie-walkie, un système et un support de stockage. Le procédé comprend les étapes consistant à : obtenir une signalisation de notification ; stocker une adresse d'un second dispositif de nœud dans une table de routage d'un premier dispositif de nœud ; générer et diffuser une signalisation de nœud nouvellement ajouté, de sorte que d'autres premiers dispositifs de nœud dans la mise en réseau mettent à jour une table de routage correspondante et une période de diffusion de signalisation de mise en réseau, la signalisation de nœud nouvellement ajouté transportant l'adresse du second dispositif de nœud ; ajuster la période de diffusion de la signalisation de mise en réseau sur la base de la table de routage du premier dispositif de nœud ; et générer une première signalisation de mise en réseau, diffuser la première signalisation de mise en réseau selon la période de diffusion ajustée et recevoir une seconde signalisation de mise en réseau diffusée par un autre premier dispositif de nœud ou un second dispositif de nœud, de sorte que le premier dispositif de nœud et le second dispositif de nœud établissent une relation de mise en réseau.
