Abstract

The present invention relates to a method of changing the telecommunication settings of a subscriber station (1) in a radio system providing a wireless subscriber interface. For easy and swift changing of the telecommunication settings the subscriber station (1) is equipped with means (13) for changing its telecommunication settings as a response to a message received by the subscriber station over the radio path, a message (S1) is transmitted to the subscriber station including new telecommunication settings, and an acknowledgement (S2) of the implementation of the new telecommunication settings is awaited from the subscriber station (1).

Claims

AMENDED CLAIMS

[received by the International Bureau on 1 September 1997 (01 09 97), original claims 1-10 replaced by amended claims 1-8 (3 pages)]

1 A method of changing the telecommunication settings of a subscriber station (1 ) in a radio system providing a wireless subscriber interface, in which method the subscriber station (1) is equipped with means (13) for changing its telecommunication settings as a response to a message received by the subscriber station over the radio path, a message (S1) containing new telecommunication settings is transmitted to the subscriber station, and an acknowledgement (S2) of the implementation of the new telecommunication settings is awaited from the subscriber station (1), characterized in that said subscriber station is equipped at least with means (13) for changing the telecommunication settings associated with the radio cell used, and a message is sent to the subscπber station for transferring it to a specific radio cell

2 A radio system providing a wireless subscriber interface and comprising a subscriber network element (6) in a data transmission connection with a local exchange (7) of a public telephone network, base stations (5, 5', 5") and subscriber stations (1 , 9), the subscriber network element (6) and said base stations (5, 5', 5") comprising means for transferring telecommunication signals between the local exchange and the subscriber stations, in which system the subscriber network element (6) comprises means for transmitting a predetermined message (S1) via a base station over the radio path to a given subscriber station (1) in order to change its telecommunication settings, and the subscriber station (1) comprises means (13, 14) for changing its telecommunication settings as a response to information contained in the message (S1), and means for transmitting an acknowledgement (S2) over the radio path via the base station to the subscriber network element (6) in order to confirm the implementation of the new telecommunication settings, characterized in that when said message (S1 ) contains a new cell identity (TA), the subscriber station (1) comprises means for going through the calling channels used by the system until it finds a calling channel using said new cell identity (TA), and the subscriber station transmits said acknowledgement (S2) to the subscriber network element (6) and moves to said new calling channel

3 A radio system as claimed in claim 2, characterized in that if the subscriber station (1 ) does not find a calling channel using said new cell identity (TA), it returns to the original calling channel without changing its telecommunication settings 4 A radio system as claimed in claim 2, characterized in that signalling between the subscriber station (1) and the subscriber network element (6) is essentially similar to that defined in NMT-900 specifications, the subscriber network element being arranged to use frame 1a, 1a', 1a" or 1b defined in NMT-900 specifications point 4 3.2 1 as said predetermined message, and the subscriber station (1) is arranged to acknowledge the implementation of the new telecommunication settings to the subscriber network element by frame 10a or 10d defined in NMT-900 specifications point 4 3.2.2

5. A subscriber station (1) of a radio system providing a wireless subscriber interface and consisting of terminal equipment (3) having a radio part (11 ), and of a user interface (2) linked to the terminal equipment by means of a two-wire line (4), said terminal equipment comprising means (13, 14) for changing the telecommunication settings of the subscriber station as a response to a predetermined message (S1) received over the radio path, characterized in that the terminal equipment (3) comprises means for 15

changing the telecommunication settings (TA) associated with the radio cell used as a response to the message (S1) received by the subscriber station (1), whereby the subscriber station (1) is arranged to switch to utilize the new radio cell assigned to it by said message (S1) 6 A subscriber station as claimed in claim 5, characterized in that the terminal equipment (3) comprises means (11 13) for transmitting a predetermined acknowledgement (S2) over the radio path as a response to the implementation of the new telecommunication settings

7 A subscriber station as claimed in claim 5, characterized in that the terminal equipment (3) comprises means for limiting the maximum transmission output level used by the subscribe station (1 ) on the basis of information included in said message (S1)

8 A subscriber station as claimed in claim 5, characterized in that the terminal equipment (3) comprises means for changing the telecommunication settings associated with the call set-up of the subscriber station (1) in order for a transparent or a non-transparent call set-up procedure to be chosen as a response to the information contained in the message (S1) received by the subscriber station
