A communications network system which is capable of continuously performing a normal communications of data on a communication cable. A Navigation unittransmits an intersection data having ID0001 to an automatic transmission control unitvia communications cable. A gatewaywhich accepts communications from an information system network B to a control system network A is intervened on a communications line between both networks. When detecting a sending data having an ID code of ID0001, gatewaycompares its communication period 0 of the data with previously stored communications period. If they are coincident with each other, the communications from network B to network A is enabled. If communications periods are incoincident with each other, the ID code when the intersection data is transmitted is changed to ID0110 and communications enabling (accepting) ID code by gateway is also changed from ID0001 to ID0110.

Communications network system using gateway

In information communication system and method applicable to an in-vehicle networking architecture, at least one first electronic equipment which is enabled to serve another electronic equipment with its function and at least one second electronic equipment which is enabled to make use of a function which another electronic equipment serves are connected to a common communication bus (network). An equipment managing apparatus connected to the common communication bus stores a function serving information representing the function that the first electronic equipment can serve and a making-use-of function information representing the function of which the second electronic equipment can make use. If both contents of the function serving information and the making-use-of function information are coincident with each other, the second electronic equipment makes use of the function of the first electronic equipment.
