Claim of US Patent No. 10,148,340

1. A method of operating a multi-core data communication system to serve a wireless relay from a relay core system and to serve User Equipment (UE) from a UE core system, the method comprising:the relay core system establishing a relay bearer between the wireless relay and the relay core system over a wireless base station;
the wireless relay receiving a wireless data request from the UE and responsively transferring an S1-MME UE data request for delivery to the UE core system and indicating a UE Identifier (ID), a Relay ID, and a Relay Core ID;
a UE Mobility Management Entity (UE-MME) in the UE core system receiving the S1-MME data request having the relay ID and the relay core ID and the UE core system responsively transferring a core-to-core message indicating the Relay ID for delivery to the relay core system;
the relay core system receiving the core-to-core message and responsively transferring a base station message directing the wireless base station to modify the relay bearer;
the UE MME in the UE core system responsively transferring an S11 bearer request having the relay ID and the relay core ID to a UE Serving Gateway (UE-SGW) in response to the S1-MME data request;
the UE-SGW receiving the S11 bearer request and responsively transferring an S5 bearer request having the relay ID and the relay core ID to a UE Packet Data Network Gateway (UE-PGW);
the UE-PGW receiving the S5 bearer request and responsively transferring a Gx bearer request having the relay ID and the relay core ID to a UE Policy Charging and Rules Function (UE-PCRF); and
the wireless relay exchanging wireless data with the UE over a UE bearer, the wireless relay and the wireless base station exchanging the user data over the UE bearer, the wireless base station and the relay core system exchanging the user data over the UE bearer, and the relay core system and the UE core system exchanging the user data over the UE bearer, wherein the UE bearer traverses the modified relay bearer between the wireless relay and the relay core system.
