Performing cell reselection (update) when a source cell is in a Cell_FACH state and a target cell supports enhanced Cell_FACH. Problem: target cell supports Enhanced Cell_FACH (i.e. Cell_FACH state in which High-Speed Downlink Packet Access, HSDPA, is used, supported or available), but source cell supports non-enhanced Cell_FACH. Solution: selecting the target cell that supports Enhanced Cell_FACH; reading system information broadcast from the target cell, the system information including high speed downlink shared channel, HS-DSCH, common system information; clearing an HS-DSCH radio network temporary identity, H-RNTI, associated with a source cell; clearing a cell RNTI, C-RNTI, associated with the source cell; resetting an HS-DSCH medium access control, MAC-ehs, entity configured in the source cell; configuring a MAC-ehs entity based on the HS-DSCH common system information; and receiving high speed downlink packet access, HSDPA, transmission in the target cell. |
