Abstract:
1. A method for congestion control in a telecommunications network, the telecommunications network supporting one or more active data sessions between a server and at least a first and second communication terminal by providing at least a first and a second bearer, respectively, the method comprising the steps of: storing a common group identifier assigned to a group comprising the at least the first and second communication terminal; storing a first individual bit rate for the first bearer and a second individual bit rate for the second bearer of the first and second communication terminals, respectively, wherein the first and second individual bit rates correspond to first and second maximum bit rates allowed on the first and second bearers, respectively; monitoring in the telecommunications network a group load indicator defined for the group of at least the first and the second terminal corresponding to the common group identifier, wherein the group load indicator corresponds to a measure of total traffic load carried on the at least first and second bearers; comparing the group load indicator of the group with a group load condition of the group of the at least first and second communication terminals corresponding to the common group identifier; and controlling congestion in the telecommunications network by reducing at least one of the first individual bit rate of the first bearer and the second individual bit rate of the second bearer when the group load indicator satisfies the group load condition; wherein the group load indicator is a measured aggregate bit rate of the group, wherein the group load condition is an aggregate bit rate threshold of the group, and wherein a case in which the group load indicator satisfies the group load condition is a case in which the measured aggregate bit rate of the group exceeds the aggregate bit rate threshold of the group.
