Abstract
Systems and methods are disclosed for a CDMA base station management gateway for integrating CDMA into an LTE Evolved Packet Core (EPC) core network. In one embodiment, a system is disclosed, comprising: a base station management gateway situated between a code division multiple access (CDMA) base transceiver station (BTS) and an Evolved Packet Core (EPC) core network, the base station management gateway also situated between an additional base station and the EPC core network, the base station management gateway The method may further comprise: a stateful interworking proxy configured to perform interworking of CDMA signaling to Evolved Universal Mobile Telecommunications System Terrestrial Radio Access (EUTRAN) signaling by using an S2a/S2b interface toward the EPC and an A10/A11 interface towards the CDMA BTS; and a packet routing virtual function configured to enable mobile devices attached to the CDMA BTS to obtain IP connectivity via the EPC core network.
