UPDATE/RESELECTION OF CELL IN PROCESS OF EXPANDED CONDITION OF CELL FORWARD ACCESS CHANNEL (CELL_FACH) Russian patent published in 2013 - IPC H04W36/10 H04W60/00 

FIELD: radio engineering, communication.

SUBSTANCE: method is proposed for update (and reselection) of a cell in process of Cell_FACH condition, in which after selection of a target cell the system information is read from a target cell, including common system information on a high-speed downlink shares channel (HS-DSCH). A radio network time identifier (RNTI), received in an initial cel, is cleaned, and a variable HS_DSCH_RECEPTION is set as TRUE. An object of access control to a transfer environment (MAC-hs) HS-DSCH is configured on the basis of general system information about HS-DSCH. Transfer of high-speed packet access along a downlink (HSDPA) is then received in a target cell, and a message CELL UPDATE is sent to notify cell modification. Transfer of HSDPA may be received using a broadcasting transfer of the common H-RNTI in the system information, reserved by the H-RNTI according to a request in a message CELL UPDATE or a time identifier, which is a subset of U-RNTI. MAC-hs may be set into the initial condition.

EFFECT: provision of soft token passing of service.
