In some embodiments, a routing device comprises a control module, a service module, and a router module. The control module may be configured to receive communication instructions from a control server. The service module may be configured to process the communication instructions and provide data path instructions based on the communication instructions. The router module may be configured to receive data from a source device and route the processed data to a target device based on the data path instructions. The control server may comprise a WiMax server such as an ASN server or a CSN server. ## Claims ### Claim 1 A system comprising: a base station configured to receive source data from a mobile device, the source data including a routing device address to send the source data to, and to generate, in a control plane protocol, control data based on the source data, the control data including a control server address to send the control data to; a control server for performing control plane functions, the control server configured to receive the control data from the base station and generate communication instructions, for carrying out data path functions, based on the control data; and a routing device for performing data plane functions, the routing device separate from the control server and comprising: a control module configured to receive the communication instructions from the control server; a service module configured to generate, in a protocol that can be read by a router module, data path instructions for the source data based on the communication instructions; and the router module configured to receive the source data from the base station and route the source data to a target device based on the data path instructions. ### Claim 2 (depends on 1) The system of claim 1, wherein the control server is a WiMAX server. ### Claim 3 (depends on 1) The system of claim 1, wherein the control server is an LTE server. ### Claim 4 (depends on 1) The system of claim 1, wherein the control server is an access server network (ASN) server and the routing device communicates with the ASN server over an R7 interface. ### Claim 5 (depends on 1) The system of claim 1, wherein the communication instructions comprise instructions to tunnel the received data using one of a plurality of generic routing encapsulation (GRE) tunnels. ### Claim 6 (depends on 1) The system of claim 1, wherein the communication instructions comprise instructions to tunnel the received data using one of a plurality of IP tunnels. ### Claim 7 (depends on 1) The system of claim 1, wherein the communication instructions comprise instructions to tunnel the received data using one of a plurality of IP tunnels and wherein the target device comprises a connectivity service network (CSN) server. ### Claim 8 (depends on 1) The system of claim 1, wherein the communication instructions comprise instructions to process the received data using a virtual local area network (VLAN) protocol. ### Claim 9 (depends on 1) The system of claim 1, wherein a connectivity service network (CSN) server comprises the routing device. ### Claim 10 A method comprising: receiving, by a base station, source data from a mobile device, the source data including a routing device address to send the source data to; generating, by the base station in a control plane protocol, control data based on the source data, the control data including a control server address to send the control data to; generating, by a control server configured to perform control plane functions, communication instructions, for carrying out data path functions, based on the control data received from the base station; receiving, by a routing device separate from the control server and configured to perform data plane functions, the communication instructions from the control server; generating, by the routing device in a protocol that can be read by a router module, data path instructions for the source data based on the communication instructions; receiving, by the router module, the source data from the base station; and routing, by the router module, the source data to a target device. ### Claim 11 (depends on 10) The method of claim 10, wherein the control server is a WiMAX server. ### Claim 12 (depends on 10) The method of claim 10, wherein the control server is an LTE server. ### Claim 13 (depends on 10) The method of claim 10, wherein the control server is an access server network (ASN) server and wherein receiving communication instructions comprises receiving communication instructions from the ASN server over an R7 interface. ### Claim 14 (depends on 10) The method of claim 10, wherein the communication instructions comprise instructions to tunnel the received data using one of a plurality of generic routing encapsulation (GRE) tunnels. ### Claim 15 (depends on 10) The method of claim 10, wherein the communication instructions comprise instructions to tunnel the received data using one of a plurality of IP tunnels. ### Claim 16 (depends on 10) The method of claim 10, wherein the communication instructions comprise instructions to tunnel the received data using one of a plurality of IP tunnels and wherein the target device comprises a connectivity service network (CSN) server. ### Claim 17 (depends on 10) The method of claim 10, wherein the communication instructions comprise instructions to route the source data using a virtual local area network (VLAN) protocol.
