This invention presents a service of barring the forwarded calls. According to the invention, a subscriber may define in his subscriber information that all calls forwarded to him are to be rejected. In response to receiving a request for establishing a call to a subscriber, his subscriber information is checked to find out if he has defined that calls forwarded to him are to be rejected. If the subscriber information shows that the subscriber wishes to reject the forwarded incoming calls, the call establishment signaling is studied to find out if the call has been forwarded. If the call is determined to have been forwarded, the call is rejected. In a preferred embodiment the subscriber may define a set of allowed numbers from which even the forwarded calls are to be accepted.

Handling of forwarded calls

The present invention relates to a method for transmitting information to a subscriber in a telephone system in connection with call establishment. In order to achieve more efficient transmission of information between the parties participating in the call establishment, a message designated for a predetermined subscriber or a group of subscribers is stored in a memory means, whereby in connection with the call establishment another party to the call establishment is identified, the message designated for the identified party is retrieved from the memory means, and said message is sent to the identified party in connection with the call establishment.

Transmission of information during call establishment

A method and a system for communicating data in a telecommunication network () in which the available capacity is not uniformly distributed is disclosed. The system comprises a controller () for tracking the locations of a mobile station () moving in the telecommunication network (), and for scheduling the data communication to or from the mobile station in accordance with the available capacity of the network.

Prioritized sending of data

Within a cellular network, an incoming voice mail message is received at a voice mail server (), adapted into a format suitable for transmission by a network connection which does not meet a delay requirement for delay sensitive information, dispatched to a mobile station (), and received, readapted and stored thereat within a storing means (). Adaptation, transmission, reception and readaptation conform to standards such as the GPRS and the UMTS. The voice mail message is dispatched directly to the mobile station () via an IP address of an ISDN address thereof. In this manner, instead of dispatching a message via the SMS, the sending of an adapted voice mail message directly to a mobile station () and storing it thereat makes it possible to avoid that a user has to poll a service center by calling in order to have the message delivered.

In a communications system, the subscriber data in a home network of a subscriber is provided with a subscriber ciphering profile, which indicates whether an unciphered call, session or data packet is to be rejected, accepted or handled in some other manner. A serving network checks the subscriber ciphering profile in one or more of the following cases: 1) for each setup of an unciphered call or connection, 2) for each unciphered packet switched data transmission session, or 3) for each packet data transmission originating from subscriber equipment, and rejects or accepts the unciphered call, connection, session, or data packet, respectively, according to the subscriber ciphering profile. As a result, unciphered calls, sessions, or packet data transmissions will be reliably rejected.

Control of unciphered user traffic

System and method for providing a service to a subscriber in a network. A specific network information of a mobile station () is provided to a service provider () which generates an individual service message on the basis of the provided network information. The provision of the network information may be dependent on a predetermined subscriber condition. Thus, the service message can be transmitted to predetermined subscribers without requiring the subscriber to generate and transmit the specific network information to the service provider ().

Method and system of providing a service to a subscriber

The invention relates to a handover method in a mobile communication system in which error correction of a radio signal can be arranged with different protection levels. The method comprises measuring the signal level and/or quality of base stations in a mobile station, the signal quality and level of the mobile station at the base station is measured, comparing measurements results thus obtained and other variables of the connection with handover criteria, and handover is performed from the source cell to the target cell, when the handover criteria are met. The invention is characterized by determining at least one handover criterion depending on error correction of the radio connection. The invention further relates to a mobile communication system for performing handover.

The present invention relates to a method of transmitting an acknowledgement to an A subscriber in a telephone system in connection with call establishment. In order to improve transmission of information between the parties to the call establishment, communications means are arranged in the system for transmitting a predetermined message, a call associated with a terminating call is received from the A subscriber, and the communication means are activated via the user interface of a subscriber station to transmit said acknowledgement message to the A subscriber.

Method of transmitting an acknowledgement to an A-subscriber

A digital data transmission system includes a transmitting party, a receiving party, a non-transparent circuit-switched data connection between the transmitting and receiving parties, a control element for changing the data transmission capacity of the data connection, and a sliding-window data flow control protocol where the number of transmitted data frames to which the transmitting party has not received an acknowledgement from the receiving party is not allowed to exceed the size of the sliding window. The transmitting and receiving parties are arranged to change the size of the sliding window when one or both of them receive information from the control element on a change in the data transmission capacity of the data connection.

Sliding-window data flow control using an adjustable window size

A mobile communications system and method for use in a high-speed data transmission between a mobile station and a mobile communications network in the mobile communications system based on time division multiple access (TDMA). The mobile communications system is arranged to use a different frequency for a transmitting direction and a receiving direction. The mobile communications system includes a time-slot allocating mechanism arranged to allocate at least two time slots in at least one of the transmitting and the receiving direction for data transmission; a time-slot employing mechanism arranged to employ time-slots asymmetrically so that in the transmitting direction and in the receiving direction a number of the time-slots corresponds to a currently required data transmission rate in each respective direction, the time-slot employing mechanism further arranged to keep allocated ones of the time-slots that are not used for data transmission; and a time-slot selecting mechanism arranged to select ones of the time-slots used for the data transmission in each direction such that even at a maximum timing advance.

Asymmetric high-speed data transmission apparatus and method in a mobile communications network

The invention relates to a handover method in a mobile communication system in which error correction of a radio signal can be arranged with different protection levels. The method comprises measuring the signal level and/or quality of neighbouring base stations (BTS) at a receiver of a mobile station (MS), comparing the measurement results thus obtained and other variables of the connection with handover criteria, and performing a handover from the source cell to the target cell, when the pre-set handover criteria are met. The method of the invention is characterized by determining at least one error connection possible for the connection in a potential target cell for the handover, determining at least one handover criterion on the basis of the determined error correction of the potential target cell, and setting the error correction of the connection in the target cell (BTS,) as said error correction of the base station of the target cell. The invention further relates to a mobile communication system for performing handover.
