Abstract

Disclosed herein is a gateway arrangement for receiving first and second types of traffic. The arrangement includes first and second gateways. The first gateway is arranged to separate the first and second types traffic. The first type of traffic is output to the second gateway. The second gateway is arranged to extract information from the first type of traffic and output the extracted information to the first gateway. The first gateway has an output interface arranged to output the second type of traffic dependent upon the extracted information.

Claims

1. A gateway arrangement for receiving traffic comprising a first type of traffic and a second type of traffic, the gateway arrangement comprising a first gateway and a second gateway, the first gateway being arranged to separate the first and second types traffic, the first type of traffic being output to the second gateway, the second gateway being arranged to extract information from the first type of traffic and output the information to the first gateway, and the first gateway having an output interface which is arranged to transmit the second type of traffic dependent upon the extracted information,

wherein the output interface is also an input interface which is arranged to receive first and second types of traffic signals, the first type of traffic is signaling traffic and the second tune of traffic is payload traffic.

2. The arrangement according to claim 1, wherein the first and second gateways are connected to a connector and the signaling traffic is sent between the first and second gateways via the connector.

3. The arrangement according to claim 2, wherein the connector is provided by a local area network.

4. The arrangement according to claim 1, wherein the first and second gateways are connected directly to each other.

5. The arrangement according to claim 1 wherein the first gateway is arranged to be connected to a mobile telecommunications network.

6. The arrangement according to claim 5, wherein the first gateway has a second interface for connecting to said mobile telecommunications network.

7. The arrangement according to claim 1, wherein the first gateway is arranged to be connected to a wired telecommunications network.

8. The arrangement according to claim 1, wherein the first and second gateways are connected via a wired connection.

9. The arrangement according to claim 1, wherein the first and second gateways are connected via a wireless connection.

10. The arrangement according to claim 1, wherein a plurality of first gateways are provided for the second gateway.

11. The arrangement according to claim 10, wherein eight of the first gateways are provided for the second gateway.

12. The arrangement according to claim 1, wherein the first gateway is arranged to alter the coding of the payload traffic.

13. The arrangement according to claim 1, wherein the second gateway is arranged to alter the protocol of the signaling traffic.

14. The arrangement according to claim 1, wherein the output interface is in accordance with ETSI E1 standard.

15. The arrangement according to claim 1, wherein the gateway arrangement is provided between a GSM environment and an IP environment.

16. The arrangement according to claim 1, wherein the extracted information is at least one of time slot and address information.

17. The arrangement according to claim 1, wherein the gateway arrangement further comprises a plurality of second gateways.

18. A gateway arranged to receive first and second types of traffic, the gateway comprising:

means for separating the first and second types of traffic;

means for outputting the first type of traffic to a second gateway for processing by the second gateway;

means for receiving a processed first type of traffic from the second gateway, whereby the second type of traffic is transmitted by the means for outputting dependent upon the processed first type of traffic received from the second gateway,

wherein the means for outputting is also means for inputting which is arranged to receive first and second types of traffic signals, the first type of traffic is signaling, traffic and the second type of traffic is payload traffic.

19. A gateway arrangement for receiving traffic comprising a first type of traffic and a second type of traffic, the gateway arrangement comprising a first gateway and a second gateway, the first gateway being arranged to separate the first and second types traffic, the first type of traffic being output to the second gateway, the second gateway being arranged to extract information from the first type of traffic arid output the information to the first gateway, and the first gateway having an output interface which is arranged to transmit the second type of traffic dependent upon the extracted information, wherein eight of the first gateways are provided for the second gateway.

20. A gateway arrangement for receiving traffic comprising a first type of traffic and a second type of traffic, the gateway arrangement comprising a first gateway and a second gateway, the first gateway being arranged to separate the first and second types traffic, the first type of traffic being output to the second gateway, the second gateway being arranged to extract information from the first type of traffic and output the information to the first gateway, and the first gateway having an output interface which is arranged to transmit the second type of traffic dependent upon the extracted information, wherein the first gateway is arranged to alter the coding of the payload traffic and the second gateway is arranged to alter the protocol of the signaling traffic.

21. A gateway arrangement for receiving traffic comprising a first type of traffic and a second type of traffic, the gateway arrangement comprising a first gateway and a second gateway, the first gateway being arranged to separate the first and second types traffic, the first type of traffic being output to the second gateway, the second gateway being arranged to extract information from the first type of traffic and output the information to the first gateway, and the first gateway having an output interface which is arranged to transmit the second type of traffic dependent upon the extracted information, wherein the output interface is in accordance with the ETSI E I standard and the extracted information is at least one of time slot and address information.

22. A, gateway arrangement for receiving traffic comprising a first type of traffic and a second type of traffic, the gateway arrangement comprising a first gateway and a second gateway, the first gateway being arranged to separate the first and second types traffic, the first type of traffic being output to the second gateway, the second gateway being arranged to extract information from the first type of traffic and output the information to the first gateway, and the first gateway having an output interface which is arranged to transmit the second type of traffic dependent upon the extracted information, wherein the gateway arrangement is provided between a GSM environment and an IP environment and the extracted information is at least one of time slot and address information.
