Abstract

A wireless data network which provides communications with a Point-to-Point Protocol server is disclosed. The network includes a home network that includes a home mobile switching center, a wireless modem and one or more end system. The wireless modem and the end systems are connected together via an ethernet link. The network also includes a PPP server, wherein PPP information sent from PPP server for the end system is encapsulated buy the wireless modem in an ethernet frame and sent to the end system via the ethernet link.

Claims

1. A wireless data network, comprising:

a home network that includes a home mobile switching center, a wireless modem, and at least one end system, the home mobile switching center including a home inter-working function; and

a PPP server,

wherein the home mobile switching center connects to the wireless modem,

wherein an ethernet link connects the wireless modem and said at least one end system, and

wherein the wireless modem encapsulates PPP information sent from the PPP server for said at least one end system in an ethernet frame and sends the ethernet frame to said at least one end system via said erhermer link.

2. The wireless data network of claim 1, wherein PPP information from said at least one end system is sent to the wireless modem via the ethernet list and then transmitted from the wireless modem to the PPP server.

3. The wireless data network of claim 1, wherein a message that includes the PPP information is coupleable from said at least one end system through the home innter-working function to the PPP server.

4. The wireless data network of claim 3, wherein PPP information from said PPP server is transmitted through the home inter-working function to the wireless modem.

5. The wireless data network of claim 4, wherein PPP information from said at least one end system is sent to the wireless modem via the ethernet link and then transmitted from the wireless modem to the PPP server through the home inter-working function.
