Abstract
A method and apparatus provide for the control of wireless communication signals over an enhanced dedicated channel (E-DCH) resource while operating in the CELL_FACH state with an allocated E-DCH radio network temporary identifier (E-RNTI). A determination is made that a periodic cell update timer is expired. In response to the periodic cell update timer expiring, a determination is made whether the WTRU has an allocated E-DCH resource. If the WTRU has an allocated E-DCH resource, the periodic cell update timer is re-started without performing a periodic cell update.

A wireless transmit/receive unit (WTRU) comprising:
- a processor configured to:
- determine whether the WTRU is operating in a CELL_FACH state with an allocated E-DCH resource at a time that a periodic cell update timer expires;
- on a condition that the WTRU is operating in the CELL_FACH state and does not have the allocated E-DCH resource at the time that the periodic cell update timer expires, perform a periodic cell update;
- and
- on a condition that the WTRU is operating in the CELL_FACH state and has the allocated E-DCH resource at the time that the periodic cell update timer expires, re-start the periodic cell update timer, wherein the periodic cell update timer is re-started without performing the periodic cell update.
A wireless transmit/receive unit (WTRU) comprising:
- a memory;
- and
- a processor, wherein the WTRU is configured to:
- operate in a CELL_FACH state with ongoing common control channel (CCCH) traffic, wherein an allocated E-DCH resource is associated with the ongoing CCCH traffic;
- prevent dedicated control channel (DCCH)/dedicated traffic channel (DTCH) data from being transmitted using the allocated E-DCH resource that is associated with the ongoing CCCH traffic;
- determine whether the WTRU is operating in the CELL_FACH state and has the allocated E-DCH resource at a time that a periodic cell update timer expires;
- and
- on a condition that the WTRU is operating in the CELL_FACH state and has the allocated E-DCH resource at the time that the periodic cell update timer expires, re-start the periodic cell update timer, wherein the periodic cell update timer is re-started without performing a periodic cell update.
A method comprising:
- operating in a CELL_FACH state with ongoing common control channel (CCCH) traffic, wherein an allocated E-DCH resource is associated with the ongoing CCCH traffic;
- preventing dedicated control channel (DCCH)/dedicated traffic channel (DTCH) data from being transmitted using the allocated E-DCH resource that is associated with the ongoing CCCH traffic;
- determining whether the WTRU is operating in the CELL_FACH state and has the allocated E-DCH resource at a time that a periodic cell update timer expires;
- and
- on a condition that the WTRU is operating in the CELL_FACH state and has the allocated E-DCH resource at the time that the periodic cell update timer expires, re-starting the periodic cell update timer, wherein the periodic cell update timer is re-started without performing a periodic cell update.
