Embodiment Construction

[0050] Throughout the drawings, the same reference numerals will be used for corresponding or analogous elements.

[0051] The present invention relates to traffic management in communication systems and networks, and in particular to techniques for managing and handling situations in which the current traffic pattern in the system differs significantly from a predefined traffic model according to which Defined business models to design and plan.

[0052] In sharp contrast to prior art admission and congestion control solutions, the present invention provides for a communication system by combining and using so-called prioritization or shaping profiles / schemas for at least a portion of the active communication terminals in the system. Partial, temporary and dynamic modification of business models in .

[0053] Said modification is local in that it generally affects only a part of the communication system, more precisely only the communication terminals present in a part of th...

Abstract

The present invention involves traffic management in a communication system (1) comprising multiple communication terminal (10, 200) that each has data flows presented in transmit buffers (14, 220). The terminals (10, 200) utilize a default priority scheme for selecting data from the buffers (14, 220) to transmit at transmission occasions determined by a schedule scheme. A switching event is detected based on information of an estimate distribution of data flows in a first portion (2) of the system (1). A priority scheme update message is generated based on this event detection. The update message comprises information of a temporary priority scheme that is to be used by terminals (10, 200) in a second portion (2; 5) of the system (1).; By using this temporary scheme that assigns new temporary priorities to the data flows, a local shaping of the transmission pattern and data flow distribution in the second system portion (2; 5) is possible.

Description

technical field [0001] The present invention relates generally to traffic management in communication systems, and in particular to traffic management causing dynamic, local and temporary changes in transmission modes in communication systems. Background technique [0002] Operators design and dimension communication systems and networks to handle specific average traffic situations. This means planning the network for a certain traffic volume and configuring it to support a given mix of application flows. In today's communication networks, there are various application flows, each of which has specific characteristics in terms of transmission quality of service (QoS) requirements, data packet size, data flow time length, daily traffic density distribution, etc. feature. The network operator uses this information to compile a business model according to which the network is planned and built. [0003] This means that a specific communication network is designed to (effect...
