Communication system, computer and method for determining a communication protocol to be used in a communication system

摘要

The invention relates to a communication system (100) with at least one first communication network (10-1, 10-2), which is designed for communication according to a first protocol. It comprises at least one second communication network (20) which is designed for communication according to a second protocol. It comprises at least a third communication network (30-1, 30-2) which is designed for communication according to the first and the second protocol, the at least one first communication network (10-1, 10-2) and / or the at least one second communication network (20) and / or the at least one third communication network (30-1, 30-2) are coupled to one another for exchanging messages. It comprises a mobile computer (40), which is designed for communication according to the first and the second protocol, as well as a target computer (42), which is designed for communication according to the first and / or the second protocol, and a computer of the first or the second or third communication network (10-1, 10-2, 30, 30-1, 30-2), the communication system being designed such that when the mobile computer (40) is connected to a network connection computer (31) of the third Communication network (30-1, 30-2) before establishing a communication connection to the target computer (42) is determined which protocol is to be used for communication with the network connection computer (31).
