BACKGROUND OF THE INVENTION The use of network services, such as call transfer and call waiting services for mobile tele- phone subscribers, in a telecommunication network has been common practice for many years. The user has to order different services separately by setting up a connection with the desired service base from his/her own terminal and giving a setting to activate the service in question. After this, the settings stored in the service base control an application server and the application produces the desired services for the terminal until the function is deactivated by again setting up a connection with the service base and changing the settings.

A problem with the above-mentioned method is the difficulty of activating and deactivating network services. If several services have to be turned on at the same time, the service base settings for each service have to be changed separately. Moreover, the difficulty of activating network services is a re- striction on comprehensive use of the possibilities created by network services. It is not possible to make network service settings that change the service functions automatically in accordance with a predeter- mined instruction. Further, it is impossible or very difficult to change the service settings of a plural- ity of different network services simultaneously.

A further problem with the use of network services is that the services cannot function unless the terminal is connected to the network. Services cannot be active if e. g. the terminal has been switched off. In addition, it is difficult and time- consuming to verify which services have been activated for the terminal. If the subscriber to the services is uncertain about his/her active services, he/she must check their status by establishing a connection sepa- rately with each service base and checking the service status there. Furthermore, verifying the service status in a graphic form is not possible.

BRIEF DESCRIPTION OF THE INVENTION The object of the present invention is to eliminate the drawbacks mentioned above or at least to significantly alleviate them.

A specific object of the present invention is to disclose a method and system for centralised and continuous management of network service profiles re- gardless of whether the subscriber's terminal is con- nected to the network or not.'Profile'here means a set of network services for a subscriber, with sub- scriber-specific settings defined for the set. A fur- ther object of the invention is to provide means for easier and faster use of network services and for eas- ier and faster changing of their settings and also to provide a possibility to use services implemented in different systems.

As for the features characteristic of the in- vention, reference is made to the claims.

The telecommunication system of the invention for service profile management comprises a telecommu- nication network, such as a mobile telephone network, together with a service base for maintaining service data for each network service used by a subscriber and for setting up the service.

Furthermore, the telecommunication system of the invention comprises a profile server connected to the terminal via a telecommunication network and con- taining storage areas for the control of the service bases of all network services used by the subscriber.

According to the invention, network services implemented for a subscriber on different service bases are assembled into profiles. A profile comprises at least one network service and the profiles are man- aged in a centralised manner from a profile server provided for the subscriber, in accordance with set- tings established in the server. A subscriber may have one or more profiles, and all profiles are defined in the profile server. Selection of service profile is effected either via control by an external signal or via activation by the subscriber, in accordance with location information, time of day and/or other func- tions programmed in the profile server.

Further, according to the invention, one or more profiles may be continuously active. The sub- scriber can also deactivate all profiles. Furthermore, the subscriber to network services can change the set- tings in the profile server from his/her own terminal or from another system, e. g. from the Internet, via service pages established there. To allow the settings to be changed and/or checked from another system, a separate server is provided, which makes it possible to transmit and change subscriber-specific settings in the profile server between systems. This provides e. g. the possibility to print out the service profiles for a subscriber in a graphic form to a terminal connected to the subscriber's telecommunication network.

The system of the invention comprises means for activating and deactivating the network services for a subscriber via a profile server. Furthermore, the system comprises means for maintaining and chang-

ing the settings and identifying the subscriber in the profile server.

According to the invention, the profile server controls the network services even if the ter- minal is not connected to the telecommunication net- work.

The invention makes it considerably easier to use network services and provides a possibility to program service profiles so that they will function in accordance with pre-established settings. Moreover, the service profiles can be caused to change easily and preferably automatically, e. g. according to time of day, location data, via activation by subscriber and/or by some other external signal. In addition, the invention makes it possible to easily change the whole profile with a single command.

Further, the invention provides an easy way for the subscriber to check his/her network services.

All profiles can be verified from the network server.

The verification can also be done in a graphic form or via some other system. Moreover, in the system of the invention, the terminal need not have a continuous connection with the telecommunication network, but the services function under the control of the profile server. The profile server preferably also allows the use of services implemented in other systems.

BRIEF DESCRIPTION OF THE DRAWING In the following, the invention will be de- scribed in detail by the aid of embodiment examples with reference to the attached drawing, which presents an embodiment of the system of the invention.

DETAILED DESCRIPTION OF THE INVENTION The system illustrated in Fig. 1 comprises a profile server 2, which is provided with storage areas

for the storage of data needed for the control of service bases 7,8,9,..., n. Further, the system comprises a terminal 3 and an external excitation 4, by means of which the functions of the profile server are controlled. The external excitation 4 may be e. g. a signal source dependent on the location of the sub- scriber's terminal. Moreover, the system comprises a server 5 provided with a graphic user interface which can be used via the Internet 6.

In an. embodiment as illustrated in Fig. 1, the user of a terminal 3 wants to create two different service profiles for his/her mobile station: profile A and profile B. Profile A comprises the following func- tions: call waiting service activated, call transfer to another number and call transfer back to the mobile station's own number if there is no answer from the former number within fifteen seconds. Profile B is the same as profile A, but without the call waiting serv- ice. The user of the mobile station wants to have pro- file A active every day from 07: 00 to 16: 00 and pro- file B at other times. He/she stores in the profile server 2 the functions required for the control of the desired profiles consisting of network services via his/her own terminal 3 or e. g. by using services cre- ated for the Internet 6.

In the Internet 6, changes can be made in subscriber-specific profiles via the service pro- vider's home pages created in a server 5. On the home pages, the subscriber is identified and can then change his/her existing profiles or create new ones in a graphic form. In the Internet, the subscriber can quickly and advantageously check the profiles cur- rently valid for him/her. In addition to the Internet, other systems or services, such as a service number, connected to the telecommunication network 1 can be used for the same purpose.

After the above-mentioned actions, the pro- file server 2 automatically changes the profile every day at 07: 00 and at 16: 00 hours. The profile server changes the profiles by sending commands to the rele- vant service bases. In the case of the above example, the profile server sends a MML command (MML, Man Ma- chine Language) to the subscriber's home location reg- ister (HLR), which in this case is a service base 7, to change the service setting. In the case of the ex- ample, no other changes need to be made after the first activation of the services because the other services are the same in both profiles.

In the case of the example, there may be nu- merous different services simultaneously and they all can be activated and deactivated in a centralised man- ner from the profile server. The functions of other network services are controlled in accordance with the settings in their own service bases 7,8,9,..., n, and all these are controlled and activated/deactivated in a centralised manner from the profile server. The activation/deactivation of the services can also be effected using an external excitation 4 supplied to the profile server. The external excitation may be any signal designed for the purpose, and the system per- mits the use of a plurality of such signals.

The invention is not restricted to the embodi- ment example described above, but many variations are possible within the scope of the inventive idea de- fined in the claims.
