Problems solved by technology

[0002] The above-mentioned devices are well known, but, as said above, they have the disadvantage that two different codes have to be entered each time the terminal is activated, or that it is too lazy to lock e.g. service card or access unit
Therefore, the device is cumbersome to operate

Embodiment Construction

[0011] In the embodiment shown in FIG. 1 , it can be seen that the terminal unit in the device 10 is a mobile phone 1 and the access unit is a user electronic service card 2 . The device also comprises button means 5 , memory 3 and microprocessing unit 4 . The telephone number can be seen in the display 6. In the exemplary embodiment shown, the device is a cellular so-called GSM mobile telephone system, in particular the CME20 system (Ericsson). In this article, it also refers to the recommended GSM11.11 system. In the embodiment shown, the card 2 with electronic memory constitutes a so-called SIM (Subscriber Identity Module) card, a more detailed description of which can be found in the proposed GSM02. identity information. A so-called IMSI (International Mobile Subscriber Identity) code is stored in the SIM card 2 . The mobile station MS can be, for example, a vehicle-mounted switchboard, a portable switchboard or a portable switchboard, which can only be used when a val...

Abstract

The present invention relates to a device (10) for rendering services such as for example telephone communication, data communication and so on comprising a terminal unit (1) and an access unit (2), the terminal unit (1) comprising terminal unit identification means (PINtm) which are stored in the terminal unit and the access unit comprising first access identification means (IMSI) in the form of a code or similar, terminal unit (1) as well as an access unit (2) being lockable. In the terminal unit are furthermore first access identification means for a given number of access units (SIM) stored wherein upon starting up of the device involving contact between terminal unit (1) and actual access unit (SIM) (2) with a certain access unit identification means (IMSIc), the code of the identification means (IMSIc) of the access unit (2) is compared to in the terminal unit (1) stored code / -s for first access iclentification means (IMSI) in the terminal unit, correspondence between stored access identification means (IMSI) and actual access unit identification means (IMSIc) leading to locking up of the terminal unit whereas non-correspondence between stored and actual access unit identification means respectively at least the terminal unit identification code (PINt) must be given.

Description

technical field [0001] The present invention relates to an apparatus for providing business services such as telephone communication, data communication and the like. The device includes a terminal unit and an access unit. The terminal unit contains inside the terminal unit identification means (PINtm) and the access unit contains first access identification means (IMSI) in the form of a code or similar, both the terminal unit and the access unit can be locked. Devices like these are open to abuse in many situations and have an extremely tempting allure to be stolen with serious consequences. This would occur, for example, if the access units could not be locked or unlocked, and the terminal units could not be locked or unlocked at the same time, so that they could not be used only by those users who are allowed to use them. This occurs, for example, when a user subscribes to a mobile phone not by using a particular mobile phone or terminal unit, but by using a separate serv...
