Embodiment 1

[0079] Example 1. A method of operating a wireless device (UE) in a radio access network, wherein an active time is defined for monitoring of downlink transmissions in an idle state following a connected state, the method comprising: in a connected state providing wireless communication with a radio access network (803, 807); receiving a disconnect message (809), the disconnect message including an indication to disable monitoring of downlink transmissions in an idle state; and in response to receiving including disabling A disconnect message indicating monitoring of downlink transmissions in an idle state, upon receipt of the disconnect message initiates (823) a power save mode for the wireless device without waiting for a duration of active time.

Embodiment 2

[0080] Example 2. The method of embodiment 1, wherein the connected state is a first connected state, and wherein the disconnect message is a first disconnect message, the method further comprising: providing wireless communication with the radio access network in the second connected state communicating (803, 807); receiving a second disconnect message (809) without an indication to disable monitoring of downlink transmissions in an idle state; and in response to receiving the second disconnect message, Monitoring (815) downlink communications from the radio access network for the duration of the active time in the idle state after receiving the second disconnect message; and initiating (823) in response to expiration of the duration of the active time Power saving mode for wireless devices.

Embodiment 3

[0081] Example 3. The method of embodiment 2, wherein providing wireless communication with the radio access network in the second connected state comprises providing wireless communication with the radio access network in the second connected state after initiating the power saving mode.

Abstract

A method of operating a wireless device in a radio access network may be provided wherein an active time is defined for monitoring of downlink transmissions in an idle state following a connected state. The method may include providing wireless communication with the radio access network in the connected state. A disconnect message may be received including an indication to disable monitoring of downlink transmissions in the idle state. In response to receiving a disconnect message including an indication to disable monitoring of downlink transmissions in the idle state, a power save mode for the wireless device may be initiated after receiving the disconnect message without waiting for a duration of active time .

Description

technical field [0001] The present disclosure relates generally to wireless communications, and more particularly to disconnect messages for communications between wireless terminals and base stations. Background technique [0002] A new feature, Power Save Mode (PSM), has been introduced in 3GPP Rel-12. It is generally described in TS23.682 V12.2.0 (2014-06) titled "Architecture Enhancements To Facilitate Communications With Packet DataNetworks And Applications" [http: / / www.3gpp.org / DynaReport / 23682.htm] Sub-entry 4.5.4, for LTE is in TS 23.401 V13.0.0 (2014-09) titled "General Packet RadioService (GPRS) Enhancements For Evolved Universal Terrestrial Radio Access Network (E-UTRAN) Access" [http: / / www.3gpp.org / DynaReport / 23401.htm] entry 4.3.22, and for 2G / 3G in TS 23.060 V13.0.0 (2014-09) titled "General PacketRadio Service (GPRS); Service Description" [ http: / / www.3gpp.org / DynaReport / 23060.htm] sub-entry 5.3.20. This feature is intended for battery powered machine-to-m...
