Abstract: A method and a system for providing easy access to an e-mail account, in particular a POP3/SMTP e-mail account, via a mobile communication network. The method comprises the steps of: providing a mobile terminal having a generic e-mail configuration with at least one default POP3/SMTP server address, setting up a connection to a server identified by the default POP3/SMTP server address via the mobile communication network using a standard POP3/SMTP protocol, and in the proxy server evaluating a user identification based on specific information assigned to the user, identifying a user e-mail account assigned to the user identification, and setting up a connection to the identified e-mail account of an e-mail system.

Abstract: The invention relates to a method an a system for providing easy access to an e-mail account, in particular a POP3/SMPT e-mail account, via a mobile communication network (1). According to the invention the method comprises the steps of: providing a mobile terminal (2) having a generic e-mail configuration with at least one default POP3/SMPT server address, setting up a connection to a server (5) identified by the default POP3/SMPT server address via the mobile communication network (1) using a standard POP3/SMPT protocol, in the proxy server (5): evaluating a user identification based on specific information assigned to the user, identifying an user e-mail account assigned to the user identification, setting up a connecting to the identified e-mail account of an e-mail system (8).

Abstract: The invention relates to a process for data exchange via a communications channel between a central unit, which processes, stores and provides data, and a data terminal device. Initially, a permanently unchanged application-independent query structure (general query structure) is stored both in the central unit and in the data terminal device, as are a small number of permanently unchanged application-independent response formats. For each application, the specific query structure is defined on the basis of the general query structure and is stored in the central unit in the form of a parameter set. As needed, the data terminal device requests from the center unit, via the communications channel, a specific query structure not yet stored in the data terminal device and receives and stores the applicable parameter set.
