Abstract

L'invention concerne un procédé et un équipement pour traiter le service de courriel sans fil. Le problème technique qui affecte l'expérience d'utilisateur est résolu, tel que lorsqu'un client MEM a besoin de se connecter de nouveau au serveur MEM, l'interface utilisateur est généralement annulée, et l'opération de l'utilisateur n'est pas continuée quand le réseau porteur est commuté. Dans l'invention, lorsqu'un terminal mobile commute du réseau d'accès source au réseau d'accès destinataire, une nouvelle liaison sur le serveur de courriel sans fil (serveur MEM) est créée dans le réseau d'accès destinataire, et une demande de commutation est envoyée au serveur de courriel sans fil (serveur MEM) pour demander de réaliser la commutation de réseau (S202) ; le serveur de courriel sans fil (serveur MEM) reçoit la demande de commutation, commute sur la nouvelle liaison, et continue de communiquer avec le terminal mobile grâce à la nouvelle liaison selon les informations stockées locales concernant le service de courriel sans fil (MEM) pour le terminal mobile (S204). Grâce à l'utilisation de l'invention, après que le réseau porteur est commuté, la continuité du service de client MEM est garantie et l'expérience d'utilisateur est améliorée.
