Abstract
The invention relates to a communication system and a method for providing a mobile telecommunication service. A communication network transmits messages on the basis of at least one internet protocol. A network connection computer connects an access network for mobile computers and the communication network. The access network is equipped with several access points comprising corresponding access point connection computers, which are configured to create a communication connection between variable access points and the mobile computers. An authorization verification computer establishes and manages trusted relationships between several communication elements. The network connection computer and the access point connection computer are configured to execute packet filtering during the receipt and transmission of messages for the secure protection of the communication system.

16. A communication system for providing a mobile telecommunication service, comprising:
-
a communication network configured to transmit messages based upon an Internet protocol;
a mobile computer;
an access network for the mobile computer in which messages are transferred using a multicast process;
a network connection computer that connects the access network to the communication network;
a plurality of access points in the access network, each access point having respective access point connection computers configured to establish a communication connection with the mobile computer; and
an authentication verification computer for establishing and managing trusted relationships between a plurality of the communication elements, wherein the network connection computer and the access point connection computer are configured to execute a packet filtering method for security-related protection of the communication system when receiving and transmitting messages, and wherein the network connection computer and the authentication verification computer are configured to execute an overload control method by providing a communication protocol for the communication elements in order to prevent a malfunction of the communication elements as a result of an attack. - View Dependent Claims (17, 18, 19, 20, 21, 22)
