1. A method comprising:at a first network device configured to operate as a small cell gateway for a Master Radio Access Point (MRAP) and a Secondary Radio Access Point (SRAP), wherein the first network device presents the MRAP and the SRAP as a single access point to a perspective of a plurality of core network functions that use the first network device to access the MRAP and SRAP:
receiving, from the MRAP, a first message comprising an indication that a first bearer is to be switched from the MRAP to the SRAP, the first message comprising:
a Tunnel Endpoint Identifier TEID for the first bearer in the SRAP identifying a GTP tunnel endpoint for the first bearer within the SRAP, and
a first transport layer address of the SRAP to which downlink data for the TEID for the first bearer in the SRAP is to be sent;
receiving first downlink user plane data for a subscriber session identified by a TEID for the first bearer in the MRAP;
replacing, for the first downlink data, the TEID for the first bearer in the MRAP with the TEID for the first bearer in the SRAP; and
sending the first downlink data to the first transport layer address using the TEID for the first bearer in the SRAP.
