US 2014/0235226 A1 · METHOD AND APPARATUS FOR SUPPORTING MACHINE-TYPE COMMUNICATIONS WITH A MOBILE-ORIGINATED-ONLY MODE

Abstract

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.

Dependent claims

A method of supporting machine-type communications implemented by a wireless transmit/receive unit (WTRU), the method comprising:

sending a message to a network, wherein the message indicates that the WTRU supports a mobile-originated-only (M-O-O) mode, wherein the message is for a trigger value for the M-O-O mode, and wherein the message is sent during one of an attach procedure, a tracking area update (TAU) procedure, or routing area update (RAU) procedure;
receiving a trigger value from the network in response to the message;
transitioning to the M-O-O mode on a condition that the trigger value expires;
and
transitioning out of the M-O-O mode on a condition that a mobile originated event occurs, wherein the mobile originated event is one of a periodic TAU procedure, a periodic RAU procedure, or transmission of mobile originated data.
