RRC Inactive Paging Cycle Updates Without Connected-State Resume

Solution Overview

Problem

Existing communication systems face challenges in efficiently updating the inactive-state paging cycle of terminal devices without requiring the terminal device to enter a connected state, leading to inefficiencies in power consumption and resource utilization.

Innovation Solution

A communication method and apparatus that allows an access network device to manage the inactive-state paging cycle by sending configuration and policy update information to the terminal device and core network elements, aligning updates without the terminal device entering a connected state, using existing signaling mechanisms to minimize additional resource usage.

Engineering Contradictions & Design Principles

1Measurement precision

If the terminal device enters a connected state to update the paging cycle, then the paging cycle can be updated, but power consumption increases and resource utilization decreases

Engineering Contradiction:

Improvepaging cycle update accuracyVSAvoidterminal device power consumption

Core Design Contradiction:

Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The patent segments the paging cycle update process into two independent parts: (1) the access network device updates the paging cycle configuration and notifies the core network element, and (2) the terminal device receives the updated configuration directly from the access network device. This segmentation eliminates the need for the terminal device to enter a connected state, thereby reducing power consumption while ensuring accurate updates at both the network and terminal sides.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The access network device performs the paging cycle update in advance by configuring the terminal device with the new paging cycle before the terminal device needs to use it. The access network device also proactively notifies the core network element of the update, ensuring that all network entities are synchronized beforehand, thus avoiding the need for the terminal device to establish a connected state for updates.

Solution Approach 1:

The patent segments the paging cycle update process into two independent parts: (1) the access network device updates the paging cycle configuration and notifies the core network element, and (2) the terminal device receives the updated configuration directly from the access network device. This segmentation eliminates the need for the terminal device to enter a connected state, thereby reducing power consumption while ensuring accurate updates at both the network and terminal sides.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The access network device autonomously manages the paging cycle update by directly configuring the terminal device and notifying the core network element without requiring terminal device participation in a connected state. This self-service approach allows the network side to handle the update independently, improving resource utilization efficiency while ensuring consistent updates across all network entities.

Inventive Principle:

Solution Approach 1:

The access network device performs the paging cycle update in advance by configuring the terminal device with the new paging cycle before the terminal device needs to use it. The access network device also proactively notifies the core network element of the update, ensuring that all network entities are synchronized beforehand, thus avoiding the need for the terminal device to establish a connected state for updates.

Inventive Principle:

Solution Approach 2:

The access network device sends notification information to the core network element about the paging cycle update, creating a feedback mechanism that ensures the core network element is aware of and synchronized with the updated paging cycle configuration. This feedback loop maintains network element synchronization while using efficient signaling mechanisms.

AI summary

A communication method includes receiving, by a first access network device or a chip configured for the first access network device, information useable to request to resume a radio resource control (RRC) connection from a terminal device, sending second information to a core network element, and sending first information to the terminal device or a second access network device. An inactive-state paging cycle of the terminal device is a first paging cycle. The second information is useable to start, cancel, or modify a mobile terminated communication handling policy of the terminal device. The first information is useable to configure the inactive-state paging cycle of the terminal device as a second paging cycle.
