Abstract

The registration at a terminal on the basis of registration data which are stored in a terminal memory and the need to deregister oneself subsequently at the same terminal has the disadvantage that, if the deregistration is forgotten, the terminal memory is unnecessarily occupied by invalid information. This is prevented if the deregistration is performed from a further terminal, the possibilities including both an explicit deregistration and an implicit deregistration on the basis of a further registration. If the registration data are split into identification data and terminal data, more efficient use is made in that case of the terminal memory and if the identification data are split into user data and service data the possibility even arises of deregistering a user at a particular terminal for some services but not for other services.

Claims20

Dependent claims

A method for deregistering a user registered at a first terminal via registration data, the first terminal being provided with a terminal memory in which the registration data is stored in response to supplied user identification information, registration location data supplied to a network being stored in a memory field of location memory means of the network, the method comprising the steps of:

supplying certain data to a second terminal by the user;
transmitting, via a second-terminal-network connection, an information signal to the network by the second terminal in response to the certain data;
adjusting, by the network, the registration location data stored in the memory field of the location memory means in response to the information signal;
transmitting, as a consequence of the information signal and via a first-terminal-network-connection, a clearing signal from the network to the first terminal;
and
in the first terminal and in response to the clearing signal received from the network, clearing at least a portion of the terminal memory so as to delete the registration data stored in the terminal memory.

3 more elements

A telecommunication system comprising a first terminal, a second terminal and a network situated between and interconnecting the first and second terminals, wherein:

the first terminal has a terminal memory for storing registration data for registering a user in response to supplied user identification information and first means for transmitting, in response to the identification information, a first information signal to the network;
the network has location memory means for storing registration location data in a memory field of the location memory means in response to the first information signal;
the second terminal has second means for transmitting, in response to certain data supplied to the second terminal, a second information signal, via a second-terminal-network-connection, to the network;
the network has means for adjusting, in response to the second information signal, the registration location data already stored in the memory field of the location memory means and third means for transmitting, as a consequence of the second information signal, a clearing signal, via a first-terminal-network-connection, from the network to the first terminal;
and
wherein the first terminal further comprises processor means for clearing, in response to the clearing signal received from the network, a portion of the terminal memory so as to delete the registration data stored in the terminal memory.
