1. A wireless network comprising:
- a first base station configured to communicate with at least one wireless device employing a wireless technology;
a cellular network gateway;
a packet network gateway;
a control server; and
a cell site gateway comprising;
a first interface connected to the first base station, the first base station communicating with the cellular network gateway through the cell site gateway;
a second interface connected to the packet network gateway;
a third interface connected to the control server to exchange control plane information to program a forwarding layer, the control plane information comprising at least one first label and at least one second label, wherein the control server exchanges the control plane information with the packet network gateway; and
the forwarding layer, wherein the forwarding layer is configured to;
transmit a second plurality of packets to the packet network gateway employing the second interface;
receive a first plurality of packets from the packet network gateway employing the second interface;
attach at least one of the at least one second label to the second plurality of packets; and
remove at least one of the at least one first label from the first plurality of packets.

Abstract
A cell site gateway comprises a first interface connected to a base station, a second interface connected to a packet network gateway, a forwarding layer, and a third interface connected to a control server. The forwarding layer transmits and receive packets. The control plane information comprises at least one first label value and at least one second label value. The control server exchanges the control plane information.

17. A wireless network comprising:
-
a first base station configured to communicate, employing a wireless technology, with at least one wireless device; a cellular network gateway; a packet network gateway; a control server; and a cell site gateway comprising; a first interface connected to the first base station, wherein the first base station is configured to communicate with the cellular network gateway through the cell site gateway; a second interface connected to the packet network gateway; a third interface connected to the control server to exchange control plane information to program a forwarding layer, the control plane information employed to program at least; a first flow entry comprising a first match field; and a second flow entry comprising a second match field; and the forwarding layer, wherein the forwarding layer is configured to; transmit, to the first base station via the first interface, a first plurality of packets if the first plurality of packets matches the first match field; and transmit, to the packet network gateway via the second interface, a second plurality of packets if the second plurality of packets matches the second match field. - View Dependent Claims (18, 19, 20)
