What is UMTS Paging?

Paging process in UMTS or HSDPA system is called UMTS Paging. The Paging Channel (PCH) is a downlink transport channel. The PCH is always transmitted over the entire cell. The transmission of the PCH is associated with the transmission of physical-layer generated Paging Indicators, to support efficient sleep-mode procedures. Paging Channel selection System information block… Read More »
