Accurate control of transmission information ad hoc networks
First Claim
1. A gateway for forwarding transmission information between a first terminal node of a first network and a second terminal node of an ad hoc network, wherein the first terminal node is addressed by a global source address and the second terminal node is addressed by an ad hoc destination address, the gateway comprising:
- a transmission/reception unit adapted to receive transmission information from said first terminal node and to transmit said transmission information to said second terminal node; and
an acknowledgment information detection unit adapted to detect the receipt of acknowledgment information from said second terminal node acknowledging that said second terminal node has received said transmission information;
wherein said transmission/reception unit comprises a first tunnel setup unit for setting up a first tunnel link between said gateway and said second terminal node by encapsulating a transmission packet received from said first terminal node and having a global source address of said first terminal node and a global destination address of said second terminal node into a modified transmission packet having an ad hoc source address of said gateway and an ad hoc destination address of said second terminal node, wherein said transmission/reception unit transmits said transmission information and receives said acknowledgment information to and from said second terminal node respectively through said first tunnel link.

Abstract
In communication system (SYS) including a first network (IN) with at least a first terminal node (CN), and an ad hoc network (AHN) with at least a second terminal node (RN1-RN4; MN), and a gateway (GW), transmission information (TI) is forwarded between the first terminal node (CN) of the first network (IN) and the second terminal node (RN1-RN4; MN) of the ad hoc network (AHN). In order to perform a more accurate flow control of transmission information (TI) inside the mobile ad hoc network (AHN), the gateway (GW) and the second terminal node (MN) exchange transmission information (TI) as well as acknowledgement information (ACTAN, ACTAN′, ACTAN″). Preferably, the exchange of the transmission information (TI) and the acknowledgement information (ACTAN, ACTAN′, ACTAN″) is carried out through a tunnel link (TUN1) established between the gateway (GW) and the second terminal node (MN).

8. A first terminal node of an ad hoc network for exchanging transmission information with a second terminal node of another network connected to said ad hoc network through a gateway, wherein the first terminal node is addressable by an ad hoc destination address and the second terminal node is addressable by a global resource address, the first terminal node comprising:
-
a transmission/reception unit adapted to receive transmission information from said another terminal node through said gateway; and an acknowledgment information transmission unit adapted to transmit to said gateway acknowledgment information acknowledging that said transmission/reception unit has received said transmission information;
whereinsaid transmission/reception unit comprise a first tunnel setup unit for setting up a first tunnel link between said second terminal node and said gateway by encapsulating a transmission packet received from said first terminal node and having a global source address of said first terminal node and a global destination address of said second terminal node into a modified transmission packet having an ad hoc source address of said gateway and an ad hoc destination address of said second terminal node, wherein said transmission/reception unit receives said transmission information and transmits said acknowledgment information from and to said gateway respectively through said first tunnel link. - View Dependent Claims (9, 10)

11. A method for forwarding transmission information between a first terminal node of a first network of a communication system and a second terminal node of an ad hoc network of said communication system, wherein the first terminal node is addressable by a global source address and the second terminal node is addressable by an ad hoc destination address, the method comprising the following steps in a gateway of said communication system:
-
setting up a first tunnel link in the ad hoc network between said gateway and said second terminal node by encapsulating a transmission packet received from said first terminal node and having a global source address of said first terminal node and a global destination address of said second terminal node into a modified transmission packet having an ad hoc source address of said gateway and an ad hoc destination address of said second terminal node and further transmitting said transmission information and receiving said acknowledgment information to and from said second terminal node respectively through said first tunnel link; receiving, in said gateway of said communication system, transmission information from said first terminal node and transmitting, from said gateway via the first tunnel link, said transmission information to said second terminal node; and detecting, in said gateway, the receipt of acknowledgment information via the first tunnel link from said second terminal node acknowledging that said second terminal node has received said transmission information. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
