METHOD FOR MANAGING CS IRAT HANDOVER FROM 2G/3G NETWORK TO LTE NETWORK |
摘要 |
The invention relates to a method to manage a CS IRAT (Circuit Switch Inter RAT) handover of a user equipment (UE) from a 2G/3G network to a LTE (Long Term Evolution) network in which: the UE transmits its CS IRAT handover from 2G/3G to LTE capabilities to the BSC/RNC node; the BSC/RNC node selects a routing paths among said different routing paths based on the UE capabilities for CS IRAT handover from 2G/3G to LTE and transmits to a MSC/VLR node (Mobile services Switching Center) of said 2G/3G network a Handover message comprising an information indicative of the selected path corresponding to the selected CS handover technology; and the MSC/VLR node transfers said Handover message to said target eNodeB through a MME (Mobility Management Entity) node or through an IWF node (Interworking Function) depending on the selected CS handover technology. |
