Revised 20/09/2018. Claim 1. The anchor base station is for use in systems comprising a built-in backhaul base station that communicates via a radio interface to the anchor base station, where the anchor base station is positioned to communicate with the cellular network service gateway (S-GW) or the mobile disengagement unit (MME) node of the user device via the transport network, where the S-GW comprises a second S-GW, where the built-in backhaul base station is accessible by the second S-GW or MME node via the anchor base station, and where the anchor base station performs the following functions: acting as a proxy between the second S-GW or MME node and the built-in backhaul base station by translating messages in the control plane and by switching data packets, resulting in the user device appearing to the second S-GW and MME node directly connected to the anchor base station in such a way that the built-in backhaul base station is hidden from the second S-GW and MME node; receiving data packets at the endpoint for the user device; Mapping data sets received from the General Packet Radio Services (GPRS) tunnelling protocol (GTP) tunnel to the outgoing GTP tunnel; receiving control messages and modifying control message elements while duplicating other elements in the control message by modifying the user device's connection indicator or by translating the beaver setup for the user device to the beaver towards the built-in backhaul base station; and forwarding modified control messages between the built-in backhaul base station and a second S-GW or MME node. (OCR) Page 1 of 2. Claims. 1. An anchor base station is used in systems consisting of a backhaul base station that communicates via a radio interface with the anchor base station, where the anchor base station is deployed to communicate with the gateway, providing cellular network services (S-GW) or a mobility disengagement unit (MME) node of the user device via the transport network. The S-GW consists of a second S-GW, which the built-in backhaul base station is accessible by the second S-GW or MME node through the anchor base station, and the anchor base station performs the following functions: acting as a proxy between the second S-GW or MME node and the anchor base station and the built-in backhaul base station by translating messages in the control plane and by switching data sets, resulting in the user device appearing to the second S-GW and MME node directly connected to the anchor base station, in such a way that the built-in backhaul base station is hidden from the second S-GW and MME node; Receive the endpoint data packet for the user's device; truncate the data packet received from the General Packet Relay Service (GPRS) tunneling protocol (GTP) tunnel; receive control messages and truncate control message elements while duplicating other elements in the control message by truncating the user's device's connection indicator or by translating the truncation of the user's device to the built-in backhaul base station; and forward the truncate control message between the built-in backhaul base station and a second S-GW or MME node. 2. The operation method at the anchor base station, configured in a system consisting of a built-in backhaul base station, communicates via a radio interface to the anchor base station, where the anchor base station communicates with the cellular network service gate (S-GW) or the mobile disengagement unit (MME) node of the user device via the transport network. The S-GW consists of a second S-GW, and the built-in backhaul base station is accessed by the second S-GW or MME node of the anchor base station. This is accomplished by: using a proxy process at the anchor base station, where the anchor base station acts as a proxy between the second S-GW or MME node and the built-in backhaul base station by sending messages in the control plane and by switching data sets. As a result, the user device appears to have the second S-GW and MME node directly connected to the anchor base station, in such a way that the built-in backhaul base station is hidden from the second S-GW and MME node. Receiving data packets with destinations for the user's device; configuring data packets received from the General Packet Radio Service (GPRS) tunneling protocol (GTP) tunneling protocol; receiving control messages and configuring elements of the control message while copying other elements in the control message by configuring the user's device's connection indicator or by translating the user device's piercer configuration to the piercer via the built-in backhaul base station; and forwarding the configured control messages between the built-in backhaul base station and a second S-GW or MME node. 3. The method specified in Claim 2, whereby the ANSOR base station will operate according to the proxy process by: maintaining the UE connection by maintaining the SI (CP) control plane connection to the built-in backhaul base station and another SI-CP connection to the MME node and mapping the UE connection indicator. 4. The bracing method specified in Reserviment Clause 2, whereby the Ansor base station will perform the proxy bracing process by: maintaining the UE's pierer connection with a GTP gunnel to the Backhall base station in 1 and another GTP gunnel to the second S-GW; and arranging the layout between the two gunnel connections. 5. The method specified in Claim 4, GTP Gunnel or UE connection identifier, where the Anchor Base Station will establish a scheduling table at the time the UE Pierreux is established.
