Abstract
The invention concerns a method, uplink traffic control device and computer program product for reducing the delay of uplink communication between a mobile station and a wireless communication network. The uplink traffic control device (21) comprises an uplink scheme determining unit (24) configured to obtain a service type indicator associated with a mobile station and determine an uplink transmission scheme based on the obtained service type indicator and a transmission control unit (30) configured to periodically grant transmissions to be made from the mobile station according to the uplink transmission scheme in order to speed up mobile station transmissions to the wireless communication network.

17. A method for scheduling uplink traffic from a mobile station to a base station in a wireless communication network, the method being performed in a node of the wireless communication network and comprising:
-
obtaining a service type indicator associated with the mobile station, said indicator providing a low priority; obtaining traffic load data concerning the traffic load in the wireless communication network; determining an uplink transmission scheme based on the obtained service type indicator; determining that the uplink transmission scheme is to be applied if the traffic load is below a traffic load threshold; and
,in response to determining that the uplink transmission scheme is to be applied, periodically granting transmissions to be made from the mobile station according to the uplink transmission scheme in order to speed up mobile station transmissions to the wireless communication network; wherein the uplink transmissions scheme is determined before mobile station transmissions are granted. - View Dependent Claims (18, 19, 20, 21, 22, 23)

32. A non-transitory computer-readable medium comprising, stored thereupon, computer program code for scheduling uplink traffic from a mobile station to a base station in a wireless communication network, wherein the computer program code is configured to cause an uplink scheme determining module of an uplink traffic control device to:
-
obtain a service type indicator associated with the mobile station, said indicator providing a low priority; determine an uplink transmission scheme based on the obtained service type indicator; determine that the uplink transmission scheme is to be applied if the traffic load is below a traffic load threshold; and
,in response to determining that the uplink transmission scheme is to be applied, periodically grant transmissions to be made from the mobile station according to the uplink transmission scheme in order to speed up mobile station transmissions to the wireless communication network, wherein the uplink transmissions scheme is determined before mobile station transmissions are granted.
