A method is provided of regulating a load placed on a first node (200) of a telecommunications network caused by transactions (Tr) sent to the first node (200) by a second node (100) of the network according to a signalling protocol between reached the first node (200) and the second node (100). The method comprises specifying a limit on the number of transactions sent from the second node (100) to the first node (200) for which a reply (R) has not yet been received, and adjusting the limit based on signals received at the second node (100) from the first node (200) that provide an indication of a level of load being experienced at the first node (200). In one example, the signalling protocol is the H.248 protocol, the signals comprise H.248.11 overload notifications, and the network is a Next Generation Network. The second node may be a gateway controller node and the first node may be a gateway node.
