Abstract

Des modes de réalisation de la présente invention portent sur un procédé, un appareil et un système de recherche de mobile, et concernent le domaine technique des communications. Le procédé consiste à : recevoir une requête de recherche de mobile envoyée par un nœud de prise en charge de service général de radiocommunication par paquets de desserte; acquérir des informations d'une cellule de résidence originale d'une station mobile recherchée conformément à la requête de recherche de mobile; et délivrer la requête de recherche de mobile à la cellule de résidence originale et à des cellules voisines de la cellule de résidence originale. Par mise en œuvre de la solution technique de la présente invention, le nombre de requêtes de recherche de mobile délivré par le BSC est réduit, et la charge d'un canal CCCH de cellule et le surdébit de signalisation d'un système sont réduits, ce qui réduit les congestions de canal CCCH dans une cellule.
