The invention relates to a data transmission in a digital mobile communication system. In a mobile communication system employing a so-called multi-channel access technique, one or more traffic channels may be allocated to a mobile station (MS) for data transfer, in accordance with the data transfer rate required by the application using the mobile station. In the invention, a data call is determined minimum and maximum requirements for the data transfer rate of the user data. The mobile communication network (BSS, MSC) dynamically adjusts (Handover CMD/Additional Assignment) the channel configuration assigned to the mobile station (MS) for the data call and consisting of one or more traffic channels, within the limits of said minimum and maximum requirements of the data channel, depending on the changing allocation state of the resources of the mobile communication network.

High-speed data transmission in a digital mobile communication system

A method of paging a mobile station to establish a packet-switched connection in a mobile telephone network that supports a circuit-switched connection and a packet-switched connection. To establish a mobile-terminated circuit-switched connection, the mobile telephone network sends the mobile station a page request, as a result of which the mobile station switches to standby mode for a circuit-switched connection. To save the batteries and to reduce the need of processing, the mobile station listens only to the paging channels of the circuit-switched connection. To establish a mobile-terminated packet-switched connection, the mobile telephone network sends the mobile station a page request via a circuit-switched connection and subsequently sends the mobile station the additional information commanding the mobile station to switch to a packet-switched connection. After detecting the additional information, the mobile station switches to the packet-switched connection.

Paging of mobile subscriber to establish packet-switched connection

A method of transmitting area-specific information on a telecommunications network. The invention comprises at least one element, e.g., a weather probe, which is external to the telecommunications system and transmits local information to the telecommunications system, which independently determines in which at least one node the information should be transmitted and, after the determination, transmits this information to at least one subscriber terminal via at least one node.

Method of transmitting area-specific information on a telecommunications network

A method and apparatus for data transmission in a time division multiple access (TDMA) mobile communication system, in which one or more time-slots may be allocated to a mobile stations for data transmission. The mobile station indicates, upon setting up a data call, to the mobile communication network a desired level of service for the user data transfer and the mobile communication network assigns the mobile station for a data call a channel configuration consisting of one or more time- slots in connection with call set-up or handover. The assigned channel configuration depends on the resources currently available in the mobile communication network and enables a data channel performance which is within the limits of the desired level of service.

Data transmission method in a TDMA mobile communication system

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.

Handover in a mobile communication system

A method for eliminating the disturbance caused by a mobile station (MS) situated within a certain area . In order to be able to prevent disturbance caused by a mobile station reliably, the mobile station (MS) is provided with control means for the muting of the mobile station as a response to a predetermined message (S ) transmitted to the mobile station, and transmitting means (BTS) are arranged in said certain area for the transmitting of said predetermined message to a mobile station situated in the area in order to mute the mobile station.

Mobile communication devices

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

In a cellular communication system, multiple TDMA time slot channels may be assigned to a single mobile station. The network may dynamically adjust, during a call, the number of channels assigned to any one mobile station based on resources available to the network and based on a level of service desired by the mobile station. In this manner, mobile stations having varying bandwidth requirements can be efficiently served by a single communication system.

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.

A data transmission in a digital mobile communication system employing a so-called multi-channel access technique, in which one or more traffic channels may be allocated to a mobile station for data transmission in accordance with the data transfer rate required by the application using the mobile station. Upon establishing a data call, the mobile station indicates to the mobile communication network the maximum and optionally the minimum requirements for the user data transfer rate. The mobile communication network assigns the mobile station for a data call a channel configuration consisting of one or more traffic channels in connection with call set-up or handover, the channel configuration depending on the resources currently available in the mobile communication network and enabling performance of the data channel, which is not lower than the minimum requirement and not higher than the maximum requirement.

For data transmission in a digital mobile communication system, in a mobile communication system employing a so-called multi-channel access technique, one or more traffic channels may be allocated to a mobile station for data transfer, in accordance with the data transfer rate required by the application using the mobile station. Minimum and maximum requirements are determined for the data transfer rate of the user data. The mobile communication network dynamically adjusts the channel configuration assignment to the mobile station for the data call, so as to consist of one or more traffic channels, within the limits of the minimum and maximum requirements of the data transfer rate, depending on the changing allocation state of the resources of the mobile communication network.
