indication scheme in a network or a part of the network is determined, and a load threshold is dynamically adjusted according to the penetration of terminals supporting a congestion indication scheme, wherein the load threshold is used for controlling load in the network or the part of the network. ## Claims ### Claim 1 An apparatus, comprising a processor configured to determine penetration of terminals supporting a congestion indication scheme in a network or a part of the network, and a threshold adjuster configured to dynamically adjust a load threshold according to the penetration of terminals supporting a congestion indication scheme, the load threshold being used for controlling load in the network or the part of the network. ### Claim 2 (depends on 1) The apparatus according to claim 1, wherein the processor is configured to control load in the network or a part of the network by determining the current load in the network or the part of the network and comparing the determined load with the load threshold. ### Claim 3 (depends on 2) The apparatus according to claim 2, wherein the processor is configured to perform an admission control, a load control and/or packet scheduling for controlling the load in the network or the part of the network. ### Claim 4 (depends on 1) The apparatus according to claim 1, wherein the processor is configured to determine the penetration of terminals supporting the congestion indication scheme based on statistics. ### Claim 5 (depends on 4) The apparatus according to claim 4, wherein the processor is configured to collect the statistics per operator, site and/or cell basis. ### Claim 6 (depends on 1) The apparatus according to claim 1, wherein the threshold adjuster is configured to increase the load threshold in case the penetration of terminals supporting the congestion indication scheme is increased. ### Claim 7 (depends on 2) The apparatus according to claim 2, wherein the processor is configured to perform an access control, in which a codec rate for at least one new call sup-porting the congestion indication scheme is determined based on the current load. ### Claim 8 (depends on 2) The apparatus according to claim 2, wherein the processor is configured to perform a load control, in which a codec rate for at least one existing call supporting the congestion indication scheme is determined based on the current load. ### Claim 9 (depends on 1) The apparatus according to claim 1, wherein the penetration of terminals supporting the congestion indication scheme is defined as a percentage of those terminals supporting the congestion indication scheme with respect to the number of all terminals present in the network or the part of the network. ### Claim 10 (depends on 1) The apparatus according to claim 1, wherein the part of the network comprises a cell and/or a group of cells. ### Claim 11 A method, comprising determining penetration of terminals supporting a congestion indication scheme in a network or a part of the network, and dynamically adjusting a load threshold according to the penetration of terminals supporting a congestion indication scheme, the load threshold being used for controlling load in the network or the part of the network. ### Claim 12 (depends on 11) The method according to claim 11, further comprising controlling load in the network or the part of the network by determining the current load in the network or the part of the network and comparing the determined load with a load threshold. ### Claim 13 (depends on 12) The method according to claim 12, wherein controlling load in the network or the part of the network comprises an admission control, a load control and/or packet scheduling. ### Claim 14 (depends on 11) The method according to claim 11, wherein the penetration of terminals supporting the congestion indication scheme is determined based on statistics. ### Claim 15 (depends on 14) The method according to claim 14, wherein the statistics are collected per operator, site and/or cell basis. ### Claim 16 (depends on 11) The method according to claim 11, wherein the load threshold is increased in case the penetration of terminals supporting the congestion indication scheme is increased. ### Claim 17 (depends on 12) The method according to claim 12, wherein controlling load of the network or the part of the network comprises an access control, in which a codec rate for at least one new call supporting the congestion indication scheme is determined based on the load. ### Claim 18 (depends on 12) The method according to claim 12, wherein controlling load of the network or the part of the network comprises a load control, in which a codec rate for at least one existing call supporting the congestion indication scheme is determined based on the load. ### Claim 19 (depends on 11) The method according to claim 11, wherein the penetration of terminals supporting the congestion indication scheme is defined as a percentage of those terminals supporting the congestion indication scheme with respect to the number of all terminals present in the network or the part of the network. ### Claim 20 (depends on 11) The method according to claim 11, wherein the part of the network comprises a cell and/or a group of cells. ### Claim 21 (depends on 11) A computer program product comprising code means for performing a method according to claim 11 when run on a processing means or module. ### Claim 22 (depends on 21) The computer program product according to claim 21, wherein the computer program product is embodied on a computer-readable medium.
