Abstract

L'invention concerne un procédé pour central de VOIP et un dispositif apparenté. Le procédé comporte les étapes consistant à: acquérir des premières informations d'identifiant global ou des deuxièmes informations d'identifiant global; lorsque les premières informations d'identifiant global sont acquises, envoyer les premières informations d'identifiant global à une station de base et une passerelle de desserte où est situé un terminal appelé, afin que la station de base et la passerelle de desserte où est situé le terminal appelé fassent fonction de central local pour un terminal appelant et le terminal appelé en fonction des premières informations d'identifiant global; et lorsque les deuxièmes informations d'identifiant global sont acquises, informer la station de base où sont situés le terminal appelant et le terminal appelé pour faire fonction de central local pour le terminal appelant et le terminal appelé en fonction des deuxièmes informations d'identifiant global. La présente invention peut être utilisée pour résoudre le phénomène de redondance de trajets existant dans la VOIP d'un réseau mobile, de façon à réduire le trafic du réseau et l'investissement dans le réseau.
