a router to separate the user traffic into voice traffic and data traffic, to communicate the voice traffic with the satellite modem, and to communicate the data traffic over the second satellite modem,
wherein the EPC CN device manages communication of user traffic from the cellular base station to the satellite modem.
2. The device of claim 1 , wherein the satellite modem communicates signaling traffic from the cellular base station over the satellite link.
3. The device of claim 1 , wherein the EPC CN device manages Internet Protocol (IP) address mapping for user traffic.
4. The device of claim 1 , wherein the user traffic over the satellite link is communicated to one or more of an IP Multimedia Subsystem (IMS), a Public Switched Telephone Network (PSTN), a Home Subscriber Server (HSS), an external network, and an EPC service node.
5. The device of claim 1 , wherein the EPC CN device comprises one or more of a Mobility Management Entity (MME), a Policy and Charging Rule Function (PCRF), a Packet Data Network Gateway (PGW) and a Serving Gateway (SGW).
6. The device of claim 1 , wherein the cellular base station comprises an Evolved Node B (eNB).
7. The device of claim 1 , wherein the cellular base station comprises a Long Term Evolution (LTE) base station.
8. A cellular system using backhaul satellite communications, the cellular system comprising:
a cellular base station; and
a Very Small Aperture Terminal (VSAT) comprising:
an Evolved Packet Core (EPC) Core Network (CN) device, and
a satellite modem connected to the EPC CN device and to communicate over a satellite link,
a second satellite modem to communicate over a second satellite link with a data service, and
a router to separate the user traffic into voice traffic and data traffic, to communicate the voice traffic with the satellite modem, and to communicate the data traffic over the second satellite modem,
wherein the cellular base station is connected to the VSAT, and the EPC CN device manages communication of user traffic from the cellular base station to the satellite modem.
9. The system of claim 8 , wherein the satellite modem communicates signaling traffic from the cellular base station over the satellite link.
10. The system of claim 8 , wherein the EPC CN device manages Internet Protocol (IP) address mapping for user traffic.
11. The system of claim 8 , wherein the user traffic over the satellite link is communicated to one or more of an IP Multimedia Subsystem (IMS), a Public Switched Telephone Network (PSTN), a Home Subscriber Server (HSS), an external network, and an EPC service node.
12. The system of claim 8 , wherein the EPC CN device comprises one or more of a Mobility Management Entity (MME), a Policy and Charging Rule Function (PCRF), a Packet Data Network Gateway (PGW) and a Serving Gateway (SGW).
13. The system of claim 8 , wherein the cellular base station comprises an Evolved Node B (eNB).
14. The system of claim 8 , wherein the cellular base station comprises a Long Term Evolution (LTE) base station.
15. A Very Small Aperture Terminal (VSAT) to provide backhaul satellite communications, the VSAT comprising:
an evolved Node B (eNB);
a satellite modem connected to the eNB and to communicate over a satellite link;
a second satellite modem to communicate over a second satellite link with a data service; and
a router to separate the user traffic into voice traffic and data traffic, to communicate the voice traffic with the satellite modem, and to communicate the data traffic over the second satellite modem,
wherein the eNB communicates signaling and user traffic to the satellite modem.
16. The device of claim 15 , wherein the user traffic over the satellite link is communicated to one or more of an EPC CN device, an IP Multimedia Subsystem (IMS), a Public Switched Telephone Network (PSTN), a Home Subscriber Server (HSS), an external network, and an EPC service node.
17. The device of claim 15 , wherein the eNB comprises a Long Term Evolution (LTE) base station.
