Abstract

Fast connections of end users to the Internet are becoming more and more common today, and the most common types of these fast connections are ADSL and cable modems. These connections are typically highly asymmetric and allow typically 500-1500 KBit per second (most typically 750 or 1500 Kbit) for the downlink and typically for example 64 KBit or 96 Kbit or 128 Kbit per second for the uplink (although standard ADSL can in principle support up to 8 Mbit per second download speed and up to 800 Kbit per second upload speed), based on the assumption that most users download much more data than they upload. However, at least for some users these limitations are highly undesirable, and these are for example users or small businesses or organizations who want to use the connection also for example for VOIP (voice over IP) communications or Video-over IP communications or conferences or for example running web servers. Actually ADSL is beginning to be replaced by VDSL in places where the distance to the nearest street switchboard is about 1.2 Kilometers or less, which in principle allows up to 52 Mbit per second Download speed and up to 16 Mbit per Second Upload speed. However, even when end users become connected directly by fiber-optics, the typical ratio of much more Downlink versus Uplink will remain. The present invention tries to solve the problem for users who need constantly or on a changing basis more Uplink, by preferably allowing users to preferably temporarily change their Uplink-Downlink ratio on a need basis, while preferably keeping the general balance across users. Other variations allow also compensating for example for variations of the average ratio across users for example according to time of day. The patent also covers some relevant issues related to IP telephony.

Claims

1-18. -18. (canceled)

19. A method that allows users to change their Uplink-Downlink ratio on at least one of the Internet and other networks, while keeping a general balance across users, comprising at least one of the following steps:

a. Compensating for variations or fluctuations of the average ratio across users by using lines with switchable directions at least part of the way;

b. Allowing users to flexibly define their desired Up-Down ratio.

20. The method of claim 19 wherein ADSL modems can at least one of:

a. Dynamically change the up and/or the down frequency or frequencies;

b. Use time-swapping between directions, so that a certain percent of the time the higher frequency is used for the down link and the lower frequency for the uplink, and another percent of the time this is reversed.

21. The method of claim 19 wherein when the user requests higher upload speed, at least one of the following features exists:

a. The user automatically has to “

pay”

by automatic corresponding reduction in the download speed available to him/her;

b. The user is automatically charged an additional amount corresponding to the percent of the time that the upload link was increased and/or the percent of the time the uplink was used in practice according to the higher speed;

c. The request for additional uplink speed can be done by the user manually in a way that can move only within a preset range;

d. Some software and/or hardware automatically senses when the user needs more upstream bandwidth, however the user can also intervene in this since an automatic decision might not really know the user'"'"'s priorities;

e. The user can define specific hours or times and/or events in which automatically the ratio changes.

22. The method of claim 19 wherein in cable modems at least one of the following features exists:

a. The protocol is changed to use multiple frequencies that can be dynamically allocated to the up and down links;

b. Different frequencies are used for one or more of the users on the same line;

c. A combination of changing the time ratio together with letting users increase or decrease also their individual slice of the shared uplink time;

d. If the users of higher uplink bandwidth have to “

pay”

by automatically reduced downlink bandwidth, then this reduction is based on lowering the priority of packets that are intended to them.

23. The method of claim 19 wherein lines with switchable direction between routers on the network are implemented by at least one of:

a. Dynamic frequency allocation;

b. Rapid time switching of the line with a variable ratio between the Up and down direction if electrical lines are used;

c. Using switches which can change an entire line or a section of a line across multiple routers from the down direction to the up direction for a few minutes or hours or more;

d. In optic fibers switching of the direction of a line can be done by optical cross-links;

e. When a line'"'"'s direction is changed, this change of direction is automatically conveyed to all the desired routers along the way, so that the relevant optic or electric line becomes regarded by all the relevant routers along the desired section as an opposite-direction line;

f. Each pair of routers can reverse one or more lines between them according to various needs without necessarily reversing them with other routers.

24. The method of claim 19 wherein the system prevents forgery of email and/or IP addresses in order to compensate for the increased ability to send outgoing email messages.

25. The method of claim 19 wherein in order to enforce different priorities at least one of the following features exists:

a. The IP protocol is changed so that the packet header carries also a priority value, which can be added by at least one of software on the user'"'"'s computer and/or by the ISP;

b. The user can assign higher priority to certain download or upload jobs, and the ISP can change the priority of the user'"'"'s outgoing packets and/or the priority of packets that will be sent back to the user;

c. The priority set by the ISP can override any priority set by the user or by any software on the user'"'"'s computer;

d. In order to enable the ISP to affect the priority of packets that are downloaded by the user, the Internet Protocol is changed so that requests for data can carry a priority value which is respected by the server that provides that data and is automatically added by the server to packets sent back from it;

e. If identical packets going to the same general area are condensed into a single copy of the identical data with a multiple list of targets, the condensed packet is given highest priority, and the priority data is dropped or the priority value is kept for each target address and is later used when reconstructing the original packets;

f. If the original condensed packet is replicated into smaller groups as it nears the destination, the priority values of the constituent packets begin to take more effect in the smaller groups.

27. The method of claim 19 wherein if an organization is using one or a few modems with one or more routers coupled to them for multiple end-user stations, the organization can set the Up-Down ratios independently for each end-station.

28. The method of claim 19 wherein the increased uplink ratio is used to enable more efficient Voice-Over-IP and/or Video-Over-IP.

29. The method of claim 28 wherein at least one of the following features exists:

a. A single phone is used which can be used both for normal phone line and for IP telephony directly through the Internet;

b. A single phone is used which can automatically switch between normal phone line to IP telephony directly through the Internet;

c. In order to solve the problem of compatibility of numbers, one or more phone-table server databases are available over the Internet, so that the Internet identity of users can be linked to their phone numbers, so that when dialing a “

normal”

number through the Internet, the system automatically first goes to one of these phone-number-servers to check if such a phone number already has an Internet identity linked to it;

d. In order to prevent people from illegally “

hijacking”

a phone number of a person or a company and linking it to the wrong Internet identity, users can get an entry that links a phone number with a given Internet identity only upon submitting sufficient evidence that they are indeed who the claim to be and indeed own the phone number in question or have the right to assign it;

e. If the user is connected through ADSL or VDSL, since at least the phone company'"'"'s switchboard and/or the ISP can know both real the phone number though which the user is connected and his/her IP address, this address can be automatically updated in the special phone-server Databases.

26. A method that allows to enforce different priorities on packets in order to enforce different priorities to various tasks as defined by the user and/or by the ISP, comprising at least one of the following steps:

a. Changing the IP protocol so that the packet header carries also a priority value, which can be added by at least one of software on the user'"'"'s computer and/or by the ISP;

b. The system first tries to establish the actual connection through the internet and then uses a special ring to alert the phoning user, but in that case the corresponding Internet phone at the called user only gets a notice that a phone call is pending but is not instructed to actually ring as long as the phoning user has not picked up the phone.

36. The method of claim 30 wherein the IP phone or the switchbox has the ability to indicate if the user is busy with another phone call and at least one of the following features exists:

a. If a normal phone-call comes in and the user is currently talking on the phone (either normally or through the Internet) then the switchbox or the special phone or the system can indicate to the phone company that the line is busy and/or indicate to the user that there is an incoming call;

b. If the incoming call is through the Internet telephony, and the user is currently speaking with someone else through the normal telephony infrastructure or through the direct Internet telephony, the Internet phone protocol indicates a busy signal to the calling user and/or indicate to the user that there is an incoming call.

38. The method of claim 30 wherein the phoning user can ring the desired user through normal telephony and if both users are near their computer or near some other Internet link that they can use, then at least one of the following features exists:

a. They can both for press some button on the phone or on the switchbox or for activate some option in the computer, and then the phone-call can immediately be switched to direct IP telephony through the internet without them having to hang-up and reconnect;

b. As soon as one of them requests the switch to IP telephony, his system automatically informs the other user'"'"'s system, and then the other user'"'"'s system automatically checks if the other user can also revert to IP telephony and in that case switches over automatically even if the other user has not pressed the convert switch;

c. The two phones automatically check if they can make the switch into direct IP telephony and if it is possible then they automatically make this switch even without any request on part of either of the users;

d. If the calling user does not know the Internet phone number of the called user and/or his/her current IP address and/or other data needed for direct VOIP contact, the calling user'"'"'s phone can first call the other user through normal telephony and then automatically exchange internet phone numbers with the called user'"'"'s phone and/or exchange other internet information, and then the two phones can immediately automatically switch to IP telephony;

e. This can work automatically with cellular phones, so that the cellular phone automatically includes also the special ID that uniquely identifies the user, and if the user is near enough to some Internet link, the phone can automatically revert to IP telephony;

f. If only one of the users is near an Internet link the phone call can automatically revert to IP telephony on this side and normal Cellular or non-cellular telephony on the other user'"'"'s side.
