For example, if the velocity of wireless communication device 101 exceeds ten miles per hour, packet router 130 would typically select a larger number of output ports to increase the likelihood that wireless communication device 101 will receive the packet.
- packet router 130 broadcasts the data packet over the plurality of output ports ( 206 ).

- the four rows shown in wireless device information database 340 represent four different wireless communication devices at different locations, as indicated by the GPS ranges for each of the IP and MAC address pairs.
- wireless device information database 340 is utilized by packet router 330 to assist in routing packets to the wireless communication devices identified in database 340 .
- the table shown in router port database 350 comprises two columns labeled GPS and ROUTER PORTS.
- the table in router port database 350 maps GPS ranges to router ports of packet router 330 .
- the GPS field shown in router port database 350 typically corresponds to the GPS field in wireless device information database 340 , so that a GPS range received by querying wireless device information database 340 can be used to query router port database 350 to determine the appropriate router ports of packet router 330 on which to broadcast a packet.
- GPS ranges 2, 3, and 4 are associated with multiple ports of packet router 330 : B+C, A+C, and A+B+C, respectively. It should be understood that although the tables shown in databases 340 and 350 on FIG. 4 only comprise four rows each in this example, the number of rows of information in these tables would typically be much greater.
- FIG. 5 is a sequence diagram that illustrates an operation of communication system 300 in an exemplary embodiment.
- wireless communication device 301 Prior to the steps shown on FIG. 5 , wireless communication device 301 has acquired an IP address from communication network 320 and has determined its current location by utilizing GPS satellites. To begin, wireless communication device 301 transmits its IP address, MAC address, and a GPS range indicating the current location of device 301 for delivery to wireless device information database 340 .
- wireless communication device 301 has an IP address of 64.173.211.241, a MAC address of 00:1D:FE:22:B2:DF, and a GPS of “RANGE 3”, which corresponds to the third row down in the table of wireless device information database 340 as shown in FIG. 4 .
- this information is provided by wireless communication device 301 and entered into wireless device information database 340 , as shown in FIG. 5 .
- packet router 330 After the database 340 has been updated with the information from wireless communication device 301 , packet router 330 receives a data packet with a destination address corresponding to the IP address of device 301 . Packet router 330 therefore queries wireless device information database 340 with the destination IP address of the received packet to determine the MAC address and GPS range associated with this IP address. Wireless device information database 340 responds to the query with the MAC address and GPS range that are stored therein for wireless communication device 301 based on the IP address in the query. Once packet router 330 receives the MAC address and GPS range for wireless communication device 301 , packet router 330 queries router port database 350 with the GPS range received from wireless device information database 340 .
- the GPS range in this case is “RANGE 3”, so when packet router 330 queries router port database 350 with this GPS range, router port database 350 returns router ports A and C to packet router 330 , as shown in the table of router port database 350 in FIG. 4 .
- packet router 330 receives a response from router port database 350 indicating that router ports A and C correspond to the GPS “RANGE 3”
- packet router 330 broadcasts the data packet over both ports A and C with the MAC address for wireless communication device 301 .
- the MAC address for device 301 was previously received by packet router 330 in response to the query to wireless device information database 340 .
- Packet router 330 broadcasts the data packet with the MAC address for wireless communication device 301 to enable device 301 to detect the packets intended for it based on its MAC address.
- wireless communication device 301 is configured to listen for data packets having this MAC address on all wireless networks that are in communication with device 301 .
- router port A communicates over a third generation (3G) CDMA wireless network
- router port C communicates over a fourth generation (4G) WiMAX wireless network
- wireless communication device 301 is a dual-mode 3G/4G device.
- wireless communication device 301 is configured to identify data packets having its MAC address on both the 3G CDMA network and the 4G WiMAX network in this example. Note that although wireless communication device is only shown in FIG. 5 as listening for packets with its MAC address at the time packet router 330 broadcasts the packet, device 301 would typically be configured to continually listen for packets with its MAC address at all times.
- wireless communication device 301 Although packet router 330 broadcasts the data packet simultaneously over both ports A and C, wireless communication device 301 first receives the data packet over the 4G WiMAX wireless network via port C of packet router 330 . Subsequently, wireless communication device 301 receives the same packet from packet router 330 over the 3G CDMA wireless network via port A. In this example, wireless communication device 301 is configured to determine whether any data packets received have already been received over a different access medium. Therefore, wireless communication device 301 processes the two packets and determines that the packet received over the 3G CDMA wireless network was already received by device 301 over the 4G WiMAX network. Thus, wireless communication device 301 discards the duplicate packet and presents only one copy of the packet to the network layer (layer 3 ) interface of device 301 .
- layer 3 network layer
- wireless communication device 301 may receive packets over a plurality of wireless access media as device 301 transitions between them.
- the received packets are processed to ensure that any duplicate packets are discarded, and the packets are then transparently presented to the layer 3 network layer of device 301 , so that the layer 3 interface of device 301 is unaware over which wireless network or networks the packets were received.
- packet router 330 could be configured to broadcast data packets over multiple router ports only when the packet is in the proximity of its target destination. This proximity determination could be based on comparing the location of wireless communication device 301 to threshold values. For example, if wireless communication device 301 is currently located in a geographic area served by a different router than packet router 330 , packet router 330 would simply forward packets to the router that is currently serving device 301 based on the GPS range or other location information in the wireless device information database 340 .
- the router that is serving the area in which wireless communication device 301 is located receives the packets from packet router 330 , that router could query wireless device information database 340 to determine that the location of device 301 is within a proximity threshold, and would therefore broadcast the packets over the ports indicated in its router port database. Effectively, as packets near their destination, a packet router that is closer to the target device will tend to broadcast the packets over a greater number of ports than a router that is farther away from the destination.
