Abstract
A device (D) is dedicated to local routing of local traffic between optionally mobile communications terminals. The device (D), which is installed, for example, in a traffic router (R) connected via a transmission network portion to a radiocommunications network including a call switch (MSC), comprises processor means serving, in the event of first and second up traffic channels being set up between calling and called terminals (T, T) and the call switch (MSC), and first and second down traffic channels being set up between the call switch (MSC) and the calling and called terminals (T, T), to compare selected data conveyed in the first up traffic channel and in at least one down traffic channel set up after the first up traffic channel and in a selected time window, and then in the event of the comparison indicating that there is a correlation between the data conveyed in those channels, to order the traffic router (R) to route locally and directly the traffic from the first up channel to the second down channel and from the second up channel to the first down channel, without the traffic being sent to the call switch (MSC).
