This paper reports a new operational mode, Group Transit Switching (GTS)" applicable to transit switching centers in a switched communication network. Group Transit Switching (GTS) proposed here is a kind of transit switching where a multiple number of trunk circuits is assigned to a route and reset in proper time as a group. In this approach, cascaded trunk circuit groups are kept connected for a period of time between specific two switching centers via so-called group transit switching center(s), where the number of trunk circuit groups being increased or decreased according to the change of traffic flow pattern on group basis. Thus, it is possible to save control load of the transit switching centers and to improve the adaptability of the communication network to traffic pattern variation. This paper also reports quantitative investigation on the traffic characteristics of GTS and the switching control load of group transit switching center, as well as some GTS application field. It is indicated that this GTS system can realize a saving of transit switching center switching control load and the flexible operation of the communication network without sacrificing the trunk efficiency of corresponding trunk circuit too much.
