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.
Claims16
A method for control of wireless communication signals implemented in a wireless transmit/receive unit (WTRU), the method comprising:
- operating in a CELL_FACH state with an allocated enhanced dedicated channel (E-DCH) radio network temporary identifier (E-RNTI);
- determining that a periodic cell update timer expires;
- determining whether the WTRU has an allocated E-DCH resource at the time the periodic cell update timer expires;
- and
- in response to a determination that the WTRU has an allocated E-DCH resource, re-starting the periodic cell update timer, wherein the periodic cell update timer is re-started without performing a periodic cell update.
A wireless transmit/receive unit (WTRU), wherein the WTRU is in a CELL_FACH state with an allocated enhanced dedicated channel (E-DCH) radio network temporary identifier (E-RNTI), comprising:
- a receiver configured to receive an allocation of an enhanced dedicated channel (E-DCH) resource;
- and
- a processor configured to determine that a periodic cell update timer expires, and to determine whether the WTRU has an allocated E-DCH resource at the time the periodic cell update timer expires, wherein the processor is further configured to re-start the periodic cell update timer in response to a determination that the WTRU has an allocated E-DCH resource, wherein the periodic cell update timer is re-started without performing a periodic cell update.
