Dataöverföringsförfarande i ett TDMA-mobilradiosystem

摘要

The data transmission method involves assigning one or more time-slots to a mobile station for data transmission, depending on the data transfer rate required by an application using the mobile station. A data call minimum and maximum requirements is determined for the user data transfer rate. The channel configuration consisting of one or more time-slots is dynamically adjusts and assigned to the mobile station for a data call within the limits of the minimum and maximum requirements of the data channel, depending on a varying allocation level of network resources of a mobile communication network. The minimum and the maximum requirements for a user data transfer rate are indicated by the mobile station to the mobile communication network, upon setting up a data call. A channel configuration consisting of one or more time-slots is assigned for a data call in connection with call set-up or handover. The channel configuration depends on the network resources currently available in the mobile communication network and enables a data channel performance which is not lower than the minimum requirement and not higher than the maximum requirement.
