Abstract  Abstract

A method for use in a source long term evolution (LTE) mobility management entity (MME) and an MME are disclosed. The method includes receiving a relocation request from an evolved Node B (eNB) determining a handover target global system for mobile (GSM)/enhanced data rates for GSM evolution (EDGE) radio access network (GERAN) system for a handover of a wireless transmit/receive unit (WTRU) based on the received relocation request identifying a serving General Packet Radio Service (GPRS) support node (SGSN) that controls a target GERAN cell and forwarding the relocation request to a target SGSN.
