Abstract

A network node receives a first service request, which includes service pattern information and a second service request. Further, the network node selects a wireless transmit/receive unit (WTRU) reader from among one or more candidate WTRUs. Also, the network node determines a WTRU state management strategy based on the service pattern information and the second service request. Further, the network node transmits, to the selected WTRU reader, a third service request in a first radio resource control (RRC) message. Moreover, the third service request is an ambient-power-enabled Internet of Things (IoT) (AIoT) service request and includes the second service request. Further, the network node receives, from the selected WTRU reader, an AIoT service response in a second RRC message. Additionally or alternatively, the network node may forward the received AIoT service response to an AIoT function (AIoTF) node. Further, the first service request is received from the AIoTF node.

Description

BACKGROUND An ambient-power-enabled Internet of Things (IoT) (AIoT) device, is a kind of IoT device that can harvest energy from the environment, such as wireless radio waves, motion, vibration, piezoelectricity, solar power, wind power, and so forth. AIoT devices are typically either battery-less or have limited energy storage, such as by using a capacitor. AIoT devices often find their usage in Industrial Wireless Senor Networks where the environment is harsh (e.g., extremely high or low temperature) and requires devices to be battery-less and maintenance-free, and have a long service life. They will also play an important role in Smart Logistics and Smart Warehousing. Their low-cost, small-form, battery-lessness and durability make AIoT devices suitable to be attached to a huge number of goods and facilitate more efficient identifying, sorting, tracking and inventory of goods. In 3rd Generation Partnership Project (3GPP) wireless communication, a device that tis capable of communicating with AIoT devices over a radio interface is called a reader or AIoT reader. SUMMARY Disclosed herein are apparatus and methods for wireless transmit/receive unit (WTRU) reader management by a base station node for ambient-power-enabled Internet of Things (IoT) (AIoT) services. In an example, a network node receives a first service request, which includes service pattern information and a second service request. Further, the network node selects a WTRU reader from among one or more candidate WTRUs. Also, the network node determines a WTRU state management strategy based on the service pattern information and the second service request. Further, the network node transmits, to the selected WTRU reader, a third service request in a first radio resource control (RRC) message. Moreover, the third service request is an AIoT service request and includes the second service request. Further, the network node receives, from the selected WTRU reader, an AIoT service response in a second RRC message. Additionally or alternatively, the network node may forward the received AIoT service response to an AIoT function (AIoTF) node. Further, the first service request is received from the AIoTF node. Additionally or alternatively, the network node may transmit, based on the determined WTRU state management strategy, a first RRC release message to the selected WTRU reader. Additionally or alternatively, the network node may transmit, based on the determined WTRU state management strategy, a second RRC release message to the selected WTRU reader. Additionally or alternatively, the second RRC release message includes configuration information for entering an RRC_Inactive state. Additionally or alternatively, the first service request is received in an N2 message. Additionally or alternatively, the second service request is an AIoT service request originating at an AIoT application function (AF). Additionally or alternatively, the AIoT service request originating at the AIoT AF includes one or more of: a target AIoT device identifier, an AIoT service type, and a target area. Additionally or alternatively, the WTRU reader is selected based on location information of the one or more candidate WTRUs. Additionally or alternatively, the location information is determined based on an AIML-based positioning calculation using collected positioning measurements of the one or more candidate WTRUs. Additionally or alternatively, the WTRU reader is selected based on a mobility state of the one or more candidate WTRUs. Additionally or alternatively, the first service request includes a list of the one or more candidate WTRUs, and a target area.
