Abstract

An ad-hoc network that includes a plurality of telephones at least one of which is a mobile repeater telephone for establishing a first telephone connection line between a first caller telephone and a first receiver telephone, and for simultaneously establishing at least one second telephone connection line between a second caller telephone and a second receiver telephone. A subset of all the mobile repeater telephones in the network each have its own unique code and a subset of the unique codes are known to a subset of all mobile repeater telephones in the ad-hoc network. The mobile repeater telephones have a software program stored on the processors of the telephones or a database that is accessible by the telephones. The software program includes a geographic map in electronic form of the area of the network and includes data about topography and obstacles and how much the obstacles attenuate the signal.

Claims

1. An ad-hoc network comprising a plurality of telephones at least one of which is a mobile repeater telephone for establishing a first telephone connection line between a first caller telephone and a first receiver telephone in the ad-hoc network, wherein at least one mobile repeater telephone has at least one transmitter, at least one receiver, a processor, and at least one repeater for repeating a signal received or transmitted by the at least one mobile repeater telephone for establishing the at least one telephone connection line, wherein the at least one transmitter, at least one receiver and at least one repeater simultaneously allow establishing at least one second telephone connection line between at least a second caller telephone and at least one second receiver telephone different from the first caller telephone and the first receiver telephone, respectively, with at least a subset of all the mobile repeater telephones in the ad-hoc network having its own unique code and at least a subset of all the unique codes of the mobile repeater telephones in the ad-hoc network are known to at least a subset of all mobile repeater telephones in the ad-hoc network, and further wherein the mobile repeater telephones in the ad-hoc network have a software program stored on the processors of the mobile repeater telephones or on a database that is accessible by the mobile repeater telephones, wherein the software program:

includes a geographic map in electronic form of the area of the ad-hoc network and includes data about the topography on the geographic map and

has all the obstacles positioned on the geographic map and how much the obstacles attenuate the signal.

2. The ad-hoc network according to claim 1, wherein the unique code is a telephone number.

3. The ad-hoc network according to claim 1, wherein a telephone connection line comprises a plurality of mobile repeater telephones in a series wherein at least one of the plurality of mobile repeater telephones also is or is not part of different telephone connection lines.

4. The ad-hoc network according to claim 1, wherein at least a subset of all the mobile repeater telephones in the ad-hoc network acts as serial or parallel transmitters of signal for establishing a telephone connection line.

5. The ad-hoc network according to claim 1, wherein a telephone connection is via Internet protocol telephony via a station with a transmitter, receiver and a repeater connected to a computer or via Voice over Internet protocol.

6. The ad-hoc network according to claim 5, wherein the repeater connected to the computer is a component in establishing a connection between the first or the second caller telephone and the first or the second receiver telephone.

7. The ad-hoc network according to claim 1, wherein the at least one mobile repeater telephone has a PS receiver (positioning system receiver).

8. The ad-hoc network according to claim 7, wherein the unique code, the position according to the PS receiver and the neighbors of at least a subset of all the mobile repeater telephones are known by at least a subset of the mobile repeater telephones.

9. The ad-hoc network according to claim 1, wherein the mobile repeater telephones communicate as half-duplex devices or walkie-talkies.

10. The ad-hoc network according to claim 7, wherein the software program is adapted to compare the positions of the mobile repeater telephones according to the PS receiver with the geographic map.

11. The ad-hoc network according to claim 1, wherein the software program is adapted to give information about whether two mobile repeater telephones are in direct connection or not.

12. The ad-hoc network according to claim 1, wherein at least one mobile repeater telephone comprises means to ensure that if the calculations show that a break will probably occur in 15 minutes, in 10 minutes, in 5 minutes, in 2 minutes, in 1 minute, or in 30 seconds the mobile repeater telephone may connect to another mobile repeater telephone and in that way maintain the conversation.

13. The ad-hoc network according to claim 12, wherein the mobile repeater telephone has an indicator that shows the power of the signal in a certain direction.

14. The ad-hoc network according to claim 13, wherein a directed antenna directs the signal and increases the power-density of the transmitted signal to the other mobile repeater telephones.

15. The ad-hoc network according to claim 1, wherein the at least one mobile repeater telephone has at least two transmitters, at least two receivers, and at least two repeaters.

16. A method for maintaining a telephone call between mobile repeater telephones in an ad-hoc network according to claim 7, which comprises comparing positions of the mobile repeater telephones according to the PS receiver to data about the topography of the area of the ad-hoc network on a geographic map in a software program stored on the mobile repeater telephone processor or on a database that is accessible by the mobile repeater telephone and the software program.

17. The method according to claim 16, wherein the positions of the mobile repeater telephones according to the PS receiver are further compared to obstacles positioned on the geographic map and how much the obstacles attenuate the signal.

18. The method according to claim 16, wherein the software gives information whether two mobile repeater telephones are in direct connection or not.

19. The method according to claim 16, wherein the mobile repeater telephone connects to another mobile repeater telephone and in that way maintain the conversation if means of at least one mobile repeater telephone shows that a break will probably occur in 15 minutes, in 10 minutes, in 5 minutes, in 2 minutes, in 1 minute, or in 30 seconds.

20. A method for configuring an ad-hoc network with mobile repeater telephones in the ad-hoc network according to claim 1, which comprises making known the unique code of at least a subset of at least one mobile repeater telephone already in the ad-hoc network to a mobile repeater telephone to be introduced into the ad-hoc network and making known the unique code of the at least one mobile repeater telephone to be introduced into the ad-hoc network to at least a subset of all mobile repeater telephones already in the ad-hoc network.

21. The method according to claim 20, wherein mobile repeater telephone neighbors of at least a subset of mobile repeater telephones already in the ad-hoc network are made known to a mobile repeater telephone to be introduced into the ad-hoc network and mobile repeater telephone neighbors of the mobile repeater telephone to be introduced into the ad-hoc network is made known to at least a subset of all mobile repeater telephones already in the ad-hoc network.

22. The method according to claim 21, wherein two mobile repeater telephones that are neighbors and loose direct contact with each other or two mobile repeater telephones that are not neighbors and establish direct contact with each other make the unique codes of the two mobile repeater telephones and whether the two mobile repeater telephones have lost or have established direct contact with each other known to at least a subset of all mobile repeater telephones in the ad-hoc network.
