Abstract

Embodiments include an improved tethering system in which a handheld device may be used by a user to reach the same network that the handheld device also provides access to for a tethering machine. Some embodiments include performing the following on a hand held device concurrently with the hand held device providing a user of the handheld device with access to a data network: receiving a packet from a tethering machine, replacing the packet'"'"'s source address with a new source address, and transmitting the packet into a wireless network. Some embodiments include receiving from the wireless network a response packet, replacing the response packet'"'"'s destination address with the packet'"'"'s source address, and transmitting the response packet to the tethering machine.

Claims

1. A machine readable storage medium having stored thereon program code that when processed by a processing core of a hand held device causes a method to be performed, said method comprising:

performing the following on said hand held device concurrently with said hand held device providing a user of said handheld device with access to a data network;

receiving a packet from a tethering machine;

replacing said packet'"'"'s source address with a new source address;

transmitting said packet into a wireless network;

receiving from said wireless network a response packet;

replacing said response packet'"'"'s destination address with said packet'"'"'s source address; and

,

transmitting said response packet to said tethering machine.

2. The machine readable storage medium of claim 16 wherein said packet is received and said response packet is transmitted from one of:

a Bluetooth interface;

a WiFi interface;

a Universal Serial Bus interface;

a local area network interface.

3. The machine readable storage medium of claim 16 wherein said wireless network is one of:

a WiFi network;

a cellular network.

4. The machine readable storage medium of claim 16 further comprising:

replacing said packet'"'"'s source port information with new source port information;

replacing said response packet'"'"'s destination port information with said packet'"'"'s source port information.
