Scheduling of delay-sensitive traffic
First Claim
1. 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 a communication session of the mobile station, said indicator indicating that the communication session has a low priority;
obtaining traffic load data concerning the traffic load in the wireless communication network;
determining an uplink transmission scheme for the communication session based on the obtained service type indicator, wherein the uplink transmission scheme specifies the periodicity of the uplink transmission as well as the data size of the transmissions;
determining that the uplink transmission scheme is to be applied, in response to determining that 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.

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.
