Method and system for providing information data (ID) using a notification system (BSYS) for an application (APP) of a terminal (EG), having the steps of: reception (S1) of a notification registration (BREG) by the notification system (BSYS) from the terminal (EG) during registration of the terminal (EG) with the notification system (BSYS), the received notification registration (BREG) having a notification address (B-ADR), for addressing a web service (WS) provided by a gateway component (GWK), and a call parameter (AP), which is dependent on a notification token (BT) of the terminal (EG); transmission (S2) of a notification (B), which contains information data (ID) as notification content (BI), by the notification system (BSYS) to the notification address (B-ADR) that the notification registration (BREG) contains; derivation (S3) of the notification token (BT) by the web service (WS), addressed by the notification address (B-ADR), of the gateway component (GWK) from the call parameter (AP) obtained, the derived notification token (BT) being transmitted to a delivery system (ASYS) together with the information data (ID) or an access address (Z-ADR) for accessing the information data (ID); identification (S4) of the terminal (EG) by the delivery system (ASYS) on the basis of the notification token (BT) obtained, and forwarding of the information data (ID) or the access address (Z-ADR) for accessing the information data (ID) to the application (APP) of the identified terminal (EG) by the delivery system (ASYS).

Methods for broadcast transmission of data in frames having multiple time slots (TS), from one transmitting node (SK) to multiple receiving nodes (EK) in a network, said method having the following steps: The sending out of at least one broadcast request message (MSH-DSCH Request IE) from the transmitter node (SK) to the receiver nodes (EK), wherein the time slots (TS) available to the transmitter node (SK) for data transmission are indicated; The transmitting back of time-slot granting messages (MSH-DSCH Grant IE) from the receiving nodes (EK), wherein at least one of the time-slots available to the respective receiver node (EK) for data transmission is in each case indicated jointly with one at the transmitter node (SK); The sending out of a confirmation message (MSH-DSCH Grant IE as Grant Confirmation) from the transmitter node (SK) to the neighboring receiving nodes (EK), wherein all of the receiving nodes (EK) are indicated in the time-slot granting messages (MSH-DSCH Grant IE) jointly with the time-slots (TS) available at the transmitter node (SK); The performing of a broadcast transmission of the data from the transmitter node (SK) to the receiver nodes (EK) in the jointly available time slots (TS).

The invention relates to methods, networks and network nodes for setting up a route in a packet-switched network comprising network nodes which are connected to one another for data engineering purposes, said route connecting a starting node to a destination node via intermediate nodes, in which a route is set up with a distance correlation to a reference route which has already been set up in the network.

The invention describes a method for secure data transmission in a wireless mesh network. A sending node (Ai) sends at least one packet (P) to at least one forwarding node (Rj). The at least one forwarding node (Rj) receives the at least one packet from the sending node (Ai) and forwards the at least one packet to one or more receiving nodes (NRk). A destination node (D1) receives the at least one packet from the at least one receiving node (NRj). The invention comprises the step of transmitting a challenge from the sending node (Ai), being a challenging node, to the at least one forwarding node (Ri) causing the at least one forwarding node (Ri), being a challenged node, to reply both to the sending node (Ai) and the at least one receiving node (NRk) with a response, the response at least comprising transformed information about one or more of the at least one packet/packets which has/have been sent form the sending node (Ai) to the destination node (D1) via the at least one forwarding node (Rj) and the at least one receiving node (NRk). The invention further comprises the step of processing the response to find out whether the at least one forwarding node (Rj) is misbehaving or not by verifying whether the transformed information is equal to an information which can be or has been derived from the requested packet/packets, wherein the processing is carried out both by the sending node (Ai) and the at least one receiving node (NRk).
摘要:
The invention relates to a method for transmitting data in a wireless radio network having a multiplicity of base stations for wirelessly sending and receiving data, wherein the base stations are wirelessly networked such that each base station can communicate wirelessly with one or more adjacent base stations. The invention is distinguished by the transmission of broadcast messages, wherein broadcast messages are transmitted between a mobile station for wirelessly sending and/or receiving data and the base stations and wherein broadcast messages are also forwarded between the base stations. These broadcast messages do not have an associated explicit connection between two units in the radio network. Moreover, the mobile station which receives a broadcast message can process this message regardless of the base station from which it originates. This avoids what are known as “hand offs”, which are used in the prior art to associate a mobile station with a new base station when the mobile station moves out of range of the earlier base station. These hand offs result in time delays which are unacceptable in safety-critical applications. The method according to the invention is particularly suitable for use in traffic systems, particularly in rail traffic systems, in which, by way of example, a train is controlled via a central unit using the radio network. In such applications, it is particularly important for no relatively long delays to arise in the data transmission, since otherwise the safety of the traffic system is no longer assured.
