Data transmission method for TDMA mobile communication system - performing dynamic adjustment of channel configuration assigned to data call within limits of minimum and maximum requirements, depending on varying allocation level of network resources

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.
