What Is Paging? Why Paging Is Required?

Answer»

Paging: This procedure is used to transmit paging information to selected UEs in idle mode, CELL_PCH or URA_PCH state using the paging control channel (PCCH).

Paging can be initiated :

  • Upper layers in the network MAY request paging, to e.g. establish a signaling connection.
  • UTRAN may initiate paging for UEs in CELL_PCH or URA_PCH state to trigger a cell UPDATE procedure.
  • UTRAN may initiate paging for UEs in idle mode, CELL_PCH and URA_PCH state to trigger READING of updated system information.
  • UTRAN may also initiate paging for UEs in CELL_PCH and URA_PCH state to release the RRC connection.
