SYSTEM AND METHOD FOR DETECTING AN ACTIVE PHONE INTERFACE

The invention relates to a method as defined in the preamble of claim 1 and to a system for detecting an active telephone subscription in a mobile station as defined in claim 7.

With a mobile device and a Dual Numbering Subscriber Identity Module (Dual Numbering-SIM) attached thereto, it is possible to select one of the two subscriptions to be active by assigning a unique personal identification number (PIN) to the subscription. All terminal calls are routed through the active subscription. Both subscriptions have their own phone numbers and 15 personal identification numbers. In addition, it is previously known to use a standardized payment display service (AoC, Advice of Charge) in a mobile station to display the cost of a call stored on the subscriber identity module memory slots on a mobile phone display.

A problem with the above-mentioned mobile subscriptions is that the user of the terminal cannot see which subscription is active at any given time. The user of the terminal has to shut down and turn on his 25 communicators and provide the personal identification number of the subscription he wants every time he does not remember which subscription is active and wants to use a particular subscription.

The object of the invention is to eliminate the above-mentioned drawbacks.

. In particular, it is an object of the invention to provide a method and system for active subscriber access; for display on a subscriber's terminal. A further object of the invention is to simplify the use of the Dual Numbe-35 ring subscriber identity module.

As regards the features of the present invention, reference is made to the claims.

The communication system for detecting an active telephone subscription according to the invention includes a communication network with a home location register (HLR). A home location register is required to maintain subscriber-specific information. The system further comprises a terminal device and a subscriber identity module connected thereto, preferably a SIM (Subscriber Identity Module) SIM. Depending on the application, the subscriber identity module is provided with memory areas for storing subscriber-specific identifier information such as subscriber numbers (MSISDN) and telephone network information.

According to the invention, a unique identifier of each subscriber connection defined therein is stored in the subscriber identity module and the identifier of the active subscriber connection is detected over the mobile network by the terminal. In the subscriber identity module, the subscriber interface ID is stored in the memory area of the payment display (AoC, Advice of Charge) instead of the call balance and currency name. Further, according to the invention, the payment display 20 must be turned off in the mobile switching center, so that making calls does not affect the parameters of the payment display and thus making a valid ID.

The invention facilitates the securing of an active ti-25 broadband and enables it to be viewed directly from a terminal, such as a mobile phone display. Furthermore, the invention allows the setting of a completely unique identifier for each subscriber connection.

In one embodiment of the invention, the terminal user, after entering the required PIN2 code for changing the subscriber identity module memory locations, sets and stores the desired identifier from the terminal in the payment display memory locations to the subscriber interface recognizing the PIN.

The system of the invention includes means for storing and modifying the identifiers of the subscriber identity modules defined in the subscriber identity module and for detecting the identity of the active subscriber subscriber device through a mobile network via a terminal.

Further, the system includes means for deactivating a pay-per-view in the mobile switching center and for changing telephone subscriber identities from a terminal.

In the following, the invention will be described in detail with reference to the accompanying examples, with reference to the accompanying drawing, which schematically illustrates a system according to the invention.

The system of Figure 1 comprises a communications network 1 comprising a mobile services switching center MSC 15 and a home location register 2 connected thereto. The system further comprises a terminal MS connected to a space identity module SIM storing memory areas 3 and 4 for storing subscriber and telephone network information.

In one embodiment of Fig. 1, the Subscriber Identity Module SIM (Subscriber Identity Module) is used as a Dual Numbering SIM card, whereby two separate GSM subscriptions are connected to one Subscriber Identity Module. The interface is selected to be active when the telephone is switched on by providing v to the terminal MS with an interface-specific PIN. According to the invention, the active subscriber information such as name and number is identified and read using a pay-as-you-read display service (AoC, Advice of Charge) defined in the space identity module memory areas for the subscriber identity module currency name (three letters). for display on a terminal. By entering the PIN2 code in the terminal, the user can access 35 to change the payment display information. For example, the currency name of another subscription is replaced by "JOB" and the call balance is replaced by "1". For example, the name "MY" and the number "2" for the call balance are stored in place of the second connected currency name. Further, in connection with these subscriptions, the pay-5 display service (AoC) in the mobile switching center MSC home register 2 is set to inactive, so that the call balance does not change when making calls. After the previous arrangements, the terminal will display the ID of the currently active telephone subscription. In the example above, the ID is "JOB 1" or "MY 2".

The invention is not limited only to the above exemplary embodiment, but many modifications are possible within the scope of the inventive idea defined by the claims.
