Abstract

A wireless router employing a technique to couple a plurality a host services or host systems and a plurality of wireless networks. A method to route data items between a plurality of mobile devices and a plurality of host systems through a common wireless router. A point-to-point communication connection is preferably established between a first host system and a common wireless router, a mobile network message at a mobile device is generated, the mobile network message is transmitted via a wireless network to the common wireless router which in turn routes a data item component of the mobile network message to the appropriate host service.

Claims

1. A method of routing data between a wireless routing system and a plurality of mobile devices operating on a plurality of wireless networks, comprising:

receiving data at the wireless routing system;

determining a mobile device identifier from the received data;

accessing a database that associates mobile device identifiers for the mobile devices with the wireless networks, wherein the database includes for each mobile device identifier (i) an indication of the wireless network that the mobile device identifier is associated with, and (ii) an indication of a current connection status of the mobile device that is associated with the mobile device identifier;

determining a particular wireless network associated with the received data using the determined mobile device identifier;

formatting a message associated with the received data according to a protocol of the particular wireless network; and

routing the formatted message from the wireless routing system to the particular wireless network.

2. A method of routing data between a wireless routing system and a plurality of mobile devices operating on a plurality of wireless networks, comprising:

receiving data at the wireless routing system;

determining from a database a mobile device identifier and a particular wireless network associated with the received data, wherein the database includes for the mobile device identifier (i) an indication of the wireless network that the mobile device identifier is associated with, and (ii) an indication of a current connection status of the mobile device that is associated with the mobile device identifier;

determining a protocol control for the particular wireless network;

formatting a message associated with the received data according to the protocol control of the particular wireless network; and

routing the formatted message from the wireless routing system to the particular wireless network.

3. An apparatus, comprising:

a wireless router that receives data messages from a plurality of host services and a plurality of mobile devices;

wherein the data messages include a mobile device identifier associated with a particular mobile device;

a database at the wireless router having information reflecting whether the particular mobile device associated with the mobile device identifier is presently connected to a particular wireless network;

wherein the wireless router is operable to;

(i) if the particular mobile device is presently connected to a particular wireless network, generate wireless network data messages including the received data messages associated with the particular mobile device, and

(ii) format the wireless network data messages according to a protocol of the particular wireless network, and

(iii) transmit the wireless network data messages from the wireless router to the particular wireless network,

wherein for each mobile device identifier, the database at the wireless router includes;

(i) an indication of the wireless network that the mobile device identifier is associated with, and

(ii) an indication of a current connection status of the mobile device that is associated with the mobile device identifier.

4. The apparatus of claim 3, further comprising:

a plurality of network interface adapters within the wireless router for each of the plurality of wireless networks;

wherein each of the plurality of network interface adapters provides protocol control for communicating data over one of the plurality of wireless networks.

5. The apparatus of claim 4, further comprising:

a plurality of wireless transport handlers within the wireless router for interfacing communications from the plurality of host services with the network interface adapters; and

wherein each of the plurality of wireless transport handlers provides data transfer control to and from a mobile device via one of the network interface adapters.

6. The apparatus of claim 3, wherein:

the database includes an indication of whether any data is pending for a particular mobile device identifier.

7. The apparatus of claim 3, wherein:

the database is configured with a data structure for tracking a status of the plurality of mobile devices.

8. The apparatus of claim 7, further comprising:

a registration services component within the wireless router for sending a registration response responsive to a registration request from a mobile device.

9. The apparatus of claim 8, further comprising:

for each mobile device registered with the wireless router;

(i) a mobile device identifier stored in a first field of the data structure comprising a numerical or alphanumerical set of data that uniquely identify the mobile device;

(ii) a network type identifier stored in a second field of the data structure for indicating the wireless network to which the mobile device is presently connected; and

(iii) a physical connection identifier stored in a third field of the data structure indicating which of a plurality of physical connections between the wireless router and the wireless network identified in the second field is being used to communicate with the mobile device.

10. The apparatus of claim 3, further comprising:

a peer-to-peer (P2P) messaging component within the wireless router;

wherein the peer-to-peer messaging component is operable to control the wireless router to send data messages between a pair of mobile devices.

11. The apparatus of claim 10, wherein:

one of the pair is out of wireless network coverage.

12. The apparatus of claim 10, wherein:

one of the pair is temporarily unavailable.

13. The apparatus of claim 10, wherein:

the data messages are sent directly between the pair.

14. The apparatus of claim 10, wherein:

the data messages sent between the pair are encrypted.
