DESCRIPTION:

BRIEF SUMMARY
BACKGROUND OF THE INVENTION

The invention relates to a method in a radio system, comprising a subscriber database containing data informing of facilities activated for the subscriber, exchanges, base stations and subscriber stations, for keeping the subscriber stations informed of the facilities activated therefor.
A typical feature of subscriber stations of radio telephone systems, i.e. radio telephones or other such terminals, is that the subscriber stations move within and from a network area, being sometimes outside the coverage area of the network and thus losing connection with the network. Due to the fact that a radio telephone may move and operate in the radio network area of several different operators and that there is no data communication between the exchanges of the radio networks, terminals, i.e. radio telephones moving at times in the area of other radio networks, may lose connection with their own actual home radio telephone network. For this reason, a radio telephone and its user have data of facilities and services activated for radio telephones which are different from respective data contained in the exchange of the home radio telephone network of the radio telephone.
Another typical feature of radio terminals is that they are used periodically, which means that they they are at times switched on and in communication with their own radio telephone network and at times switched off, closed, and thus without communication with the radio telephone network. Additionally, radio telephones may sometimes lose connection with the radio telephone network, because a radio telephone power source, typically a battery, runs out of power. Furthermore, one radio telephone may have several users in some cases, a typical example of which is common use of a radio telephone in a company.
On account of the above facts, there is also a risk that a radio terminal and its user, on the one hand, and an exchange of a radio telephone system and an associated database, on the other hand, have different information of which operations have been programmed in the terminal to be implemented by the exchange of the radio telephone network. The user of a radio terminal, for instance, may then believe that no call transfer has been activated for calls addressed to their terminal, even though it is so in reality, and accordingly, the subscriber waits for calls to come to his or her terminal in vain, since these calls have been transferred elsewhere. In addition to the call transfer facility or call diversion facility, being a facility by means of which incoming calls can be transferred to an exchange, to a call request service implemented in connection with the exchange or to another subscriber number, there are other services implemented by the exchange and to be activated for the subscriber, whereby it is of utmost importance for the subscriber using the subscriber unit to know of an activation, i.e. a status, of these services. A further telecommunications service of this kind is a call restriction facility restricting outgoing and incoming calls. Call restrictions are, e.g., a barring of long-distance and international calls and a barring of incoming or outgoing calls. Such a call restriction may, for instance, be activated if the subscriber has not paid his or her telephone bill. Another example of the call restriction facility may be a facility preventing the subscriber from using his or her terminal for other purposes than for emergency calls. Except for these above-mentioned facilities, a large number of other facilities and telecommunications services to be provided by means of these facilities exist or are developed Just now, whereby the subscriber using the terminal should know of the activation or status of these services as far as his or her particular terminal is concerned.
According to the prior art, various attempts have been made to satisfy the above need of the subscriber to be informed of which telecommunications services and associated facilities have been activated for the terminal used by the subsc
