Method for reducing costs during the transfer of unidirectional information flows
View Patent ↗During the output of data and distribution services, user data streams frequently transferred to a corresponding communication device (i.e. information output system and/or the distribution system) are possibly irrelevant to the server. Despite this, resources for the processing of incoming useful data flows inside the communication device are provided in many cases on account of compatibility grounds. As a result, energy is reduced in the communication device. According to the invention, in order to reduce the efforts involved in processing useful data transferred in the direction of the communication device, at least one part of useful data is discarded prior to the implementation of working steps provided for the processing of useful data.
1. A method for reducing a cost of processing user data transmitted in the direction of a communication device, wherein a bidirectional connection between the communication device and a communication partner entity is established for a service, and wherein the service does not require the user data transmission to the communication device, the method comprising:
transmitting user data from the communication partner to the communication device;
discarding at least part of the user data;
transmitting information from the communication device to the communication partner entity indicating a trouble-free transmission of the user data from the communication partner entity to the communication device, the information relating to a transmission quality of the user data transmitted from the communication partner entity to the communication device;
wherein the user data is transmitted as a user data packet over a packet-oriented network in the direction of the communication device;
wherein at least a part of a plurality of user data packets arriving at the communication device from the communication partner are filtered;
wherein the filtered data packets are discarded; and
wherein the filtering is based on a port address.
2. The method according to claim 1 , wherein the communication device is an information output system or a distribution system.
3. The method according to claim 1 , wherein the communication partner entity is a terminal or a gateway.
4. The method according to claim 1 , wherein a router upstream from the communication device discards the at least part of the user data.
5. The method according to claim 1 , wherein the user data packet is transmitted in accordance to a real time protocol (RTP).
6. The method according to claim 1 , wherein the information is transmitted in accordance to a real time control protocol (RTCP).
7. The method according to claim 1 , wherein RTP packets are discarded.
8. A communication system having a connection between a communication partner entity and a communication device, comprising:
a filter for identifying user data transmitted from the communication partner entity to the communication device;
a simulation information transmitted to the partner entity to simulate a trouble-free transmission of the user data from the communication partner entity, said simulation information relating to a transmission quality of the user data transmitted from the communication partner entity to the communication device;
wherein a plurality of data packets arriving at the communication device are filtered;
wherein the filtered data packets are discarded; and
wherein the filtering is based on a port address.
9. The communication system according to claim 8 , wherein the user data is transmitted as a user data packet over a packet-oriented network in the direction of the communication device.
10. The communication system according to claim 9 , wherein the information is transmitted in accordance to a real time control protocol (RTCP).
11. The communication system according to claim 8 , wherein a router upstream from the communication device discards the at least part of the user data.
12. The communication system according to claim 8 , wherein the user data packet is transmitted in accordance a real time protocol (RTP).
13. The communication system according to claim 8 , wherein RTP packets are discarded.
14. A router in a connection path for a connection between a communication partner entity and a communication device, comprising:
a filter for discarding at least part of user data transmitted from the communication partner entity to the communication device;
a simulation information transmitted to the partner entity to simulate a trouble-free transmission of the user data from the communication partner entity, said simulation information relating to a transmission quality of the user data transmitted from the communication partner entity to the communication device;
wherein user data is transmitted as user data packets over a packet-oriented network in the direction of the communication device;
wherein the user data packets arriving at the communication device are filtered;
wherein filtered user data packets are discarded; and
wherein the filtering is based on a port address.
15. The router according to claim 14 ,
wherein user data is transmitted as user data packets over a packet-oriented network in the direction of the communication device, and
wherein the user data packets are transmitted in accordance to a real time protocol (RTP).
16. The router according to claim 14 , wherein user data is transmitted as user data packets over a packet-oriented network in the direction of the communication device.
17. The router according to claim 16 , wherein the information is transmitted in accordance to a real time control protocol (RTCP).
18. The router according to claim 14 , wherein RTP packets are discarded.
