Abstract

An optimized communications system for radio-assisted traffic services such as railroad services. In addition to the fixed-position central services and the fixed-position decentralized control centers, one or more decentralized gateway computers are introduced into the traffic network, with the communication between the mobile objects and the fixed-position objects being provided via the gateway computers.

Claims

1. A communications system for radio-assisted traffic services for radio transmission of data between mobile objects and central services and fixed-position objects, which have decentralized control centers, using at least one gateway computer, wherein

communication between the mobile objects and the fixed-position objects is implemented via the at least one gateway computer such that

for the mobile objects which communicate with the at least one gateway computer, one substitute object is set up in the at least one gateway computer and in the fixed-position objects, and

for the fixed-position objects which communicate with the at least one gateway computer, substitute objects are set up directly in the at least one gateway computer or indirectly via at least one information server,

using an update process, substitute information in the at least one gateway computer and in the fixed-position objects is updated directly between the substitute objects in the at least one gateway computer and the fixed-position objects, or indirectly between the at least one gateway computer and the information server, and

wherein if information servers are connected between the at least one gateway computer and the central services as well as decentralized control centers, the update information is cascaded, and compressed information about accessible mobile objects is produced in the information server.

2. The communications system as claimed in claim 1, wherein the compressed information is configured to be called by fixed-position objects.

3. The communications system as claimed in claim 1, wherein the information servers actively communicate with fixed-position objects and filter and/or distribute update information.
