Abstract
A wireless network site comprises a base station and a cell site gateway. The cell site gateway comprises a first interface connected to the base station, a second interface connected to a packet network gateway, a forwarding layer, and a third interface connected to a control server to exchange control plane information. The forwarding layer transmits and receive packets. The control plane information comprises at least one first label value for transmitting a first plurality of packets to the base station and at least one second label value for transmitting a second plurality of packets to the packet network gateway.
Claims20
A wireless network site comprising:
- (a) a first base station, the first base station:
- (i) communicating employing a wireless technology with at least one wireless device;
- and
- (ii) communicating with a cellular network gateway through a cell site gateway;
- and
- (b) the cell site gateway, the cell site gateway comprising:
- (i) a first interface connected to the first base station;
- (ii) a second interface connected to a packet network gateway;
- (iii) a third interface connected to a control server to exchange control plane information to program a forwarding layer, the control plane information comprising at least one first label value and at least one second label value,
- wherein the control server exchanges the control plane information with the packet network gateway;
- and
- (iv) the forwarding layer for:
- (1) transmitting a second plurality of packets to the packet network gateway employing the second interface;
- (2) receiving a first plurality of packets from the packet network gateway employing the second interface;
- (3) attaching at least one of the at least one second label to the second plurality of packets;
- and
- (4) removing at least one of the at least one first label from the first plurality of packets.
