Method and apparatus for supporting machine-type communications with a mobile-originated-only mode

摘要

A method and apparatus for supporting machine-type communications (MTC) are disclosed. A wireless transmit/receive unit (WTRU) may configure itself to operate in a mobile-originated-only mode. The WTRU may perform no, or a subset of, radio resource control (RRC) idle and/or non-access stratum (NAS) idle/standby state procedures in the mobile-originated-only mode. For example, the WTRU may perform cell reselection but not paging monitoring in the mobile-originated-only mode. Alternatively, the WTRU may perform paging monitoring but not cell reselection and location update. The operation in the mobile-originated-only mode may be triggered explicitly or implicitly. For example, the WTRU may operate in the mobile-originated-only mode if an inactivity timer expires. The WTRU may switch the mode in accordance with a pre-configured schedule. After transition of the operation mode, the WTRU may send a message to the network indicating such mode switch.

主权项

1. A wireless transmit/receive unit (WTRU) supporting machine-type communications for use in a wireless network, comprising:
a first WTRU timer that indicates to the WTRU to change from a mobile originated-and-terminated-mode to a mobile-originated-only mode, in which the WTRU is attached to a wireless communications network and performs no cell reselection, no location update procedures, no system information monitoring, or no paging monitoring while attached to the network; a second WTRU timer that indicates to the WTRU to change from the mobile-originated-only mode to the mobile originated-and-terminated-mode; and a processor comprising executable instructions to change the WTRU from the mobile originated-and-terminated-mode to the mobile-originated-only mode in response to the first WTRU timer, and to change the WTRU from the mobile-originated-only mode to the mobile originated-and-terminated-mode in response to a mobile origination event or the second WTRU timer.
