INTER-RADIO ACCESS TECHNOLOGY (IRAT) MEASUREMENT METHOD WHEN IN TD-SCDMA CONNECTED MODE

摘要

When a user equipment (UE) is operating in connected mode in a Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) network all time slots may be allocated to communications, leaving insufficient time for the UE to perform measurement of neighboring radio access technologies (RATs). When the UE moves out of TD-SCDMA coverage, it may report to the base station and receive an instruction to switch into time division multiplexing (TDM) mode and to perform inter-RAT measurement while in TDM mode.
