Abstract
The present invention relates to a method in a radio communication system providing packet data services. A radio communication system providing packet data services and a packet data scheduler (PS) are also disclosed. In accordance with the method capacity is requested for a packet data bearer, whereafter capacity is allocated for the packet data bearer based on a first timing scheme. The allocated capacity may be modified based on a second timing scheme. The packet data scheduler (PS) comprises two timers (T1, T2) fore implementing the two different timing schemes.
Claims25
A method in a radio communication system providing packet data services, comprising:
- receiving a request for a packet data bearer at a packet data scheduler apparatus;
- allocating capacity for the packet data bearer based on a first timing scheme using a first timing entity;
- and
- modifying the allocated capacity based on a second timing scheme using the first timing entity or a second timing entity, wherein the allocating capacity for the packet data bearer and the modifying the allocated capacity are based on two time periods, an allocation period and a bitrate modification period respectively, and are repeated periodically in accordance with the respective timing schemes,
- wherein at least one of the capacity allocation or capacity modification are based on load information from at least one of a base station or a mobile station of the radio communication system, and
- wherein an additional modification step is accomplished between periodical modifications defined by said second timing scheme, if a triggering condition is satisfied.
A radio communication system providing packet data services, comprising:
- a packet data scheduler, said scheduler being arranged to allocate capacity for at least a packet data bearer and to modify the allocated capacity;
- a first timer for timing the allocation of capacity for the packet data bearers;
- and
- a second timer for timing the modification of the allocated capacity, wherein the packet data scheduler is arranged to accomplish the capacity allocation and the capacity modification periodically based on two time periods, an allocation period and a bitrate modification period respectively,
- wherein said allocation period and said bitrate modification period occur at regular respective intervals, and
- wherein an additional modification step is accomplished between periodical modifications defined by a second timing scheme, if a triggering condition is satisfied.
A packet data scheduler for a radio communication system, comprising:
- an interface configured to receive a request for a packet data bearer;
- a first timer for timing an allocation of capacity for at least said packet data bearer;
- and
- a second timer for timing a modification of the allocated capacity, wherein the packet data scheduler is arranged to accomplish the capacity allocation and the capacity modification periodically based on two time periods, an allocation period and a bitrate modification period respectively,
- wherein said allocation period and said bitrate modification period occur at regular respective intervals, and
- wherein an additional modification step is accomplished between periodical modifications defined by a second timing scheme, if a triggering condition is satisfied.
A radio communication system providing packet data services, comprising:
- means for receiving a request for a packet data bearer;
- means for allocating capacity for at least said packet data bearer and for modifying the allocated capacity;
- means for timing the allocation of capacity for the packet data bearers;
- and
- means for timing the modification of the allocated capacity, wherein the means for allocating accomplishes capacity allocation and the capacity modification periodically based on two time periods, an allocation period and a bitrate modification period respectively,
- wherein said allocation period and said bitrate modification period occur at regular respective intervals, and
- wherein an additional modification step is accomplished between periodical modifications defined by a second timing scheme, if a triggering condition is satisfied.
