Idle Mode Paging for Direct Device Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional communication systems in idle mode require establishing an RRC connection to control communication devices, which is inefficient for quick instruction delivery and mobility management.
Innovation Solution
A method and apparatus that allow communication devices to check for and respond to messages with secondary identifier values associated with specific actions, enabling quick instruction delivery without establishing an RRC connection by using a first identifier value to determine resource allocation for message transmission, including secondary identifier values that are recognizable for specific actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional RRC connection establishment is used to control communication devices in idle mode, then reliable instruction delivery is achieved, but instruction delivery time is increased and system efficiency is reduced
Solution Approach 1:
The patent extracts the essential control function from the complete RRC connection establishment procedure. By using a simplified paging message format that can directly carry control instructions or trigger immediate actions, the system removes the unnecessary overhead of full RRC connection setup while retaining the core capability to deliver control instructions to idle mode devices.
Solution Approach 2:
The patent prepares communication devices in advance by configuring them with specific identifier values and action associations before idle mode operations are needed. Devices are pre-configured to recognize certain identifier patterns in paging messages and automatically execute associated actions (such as traffic switching or cell reselection) without requiring real-time connection establishment, thus achieving both speed and reliability.
2Ease of operation
If RRC connection is established for every control operation, then accurate device control is achieved, but device complexity and signaling overhead are increased
Solution Approach 1:
The patent segments the control message into distinct identifier fields and action indicators that can be independently processed. The paging message contains a primary identifier for device identification and additional identifier values that encode specific control actions. This segmentation allows the device to parse and execute relevant actions without establishing a full connection, reducing complexity while maintaining control accuracy.
Solution Approach 2:
The patent enables communication devices to autonomously interpret and execute control instructions embedded in paging messages. Devices self-configure their response behavior based on pre-associated actions with identifier values, eliminating the need for complex connection management and back-and-forth signaling. The device independently determines which actions to take based on the received identifier patterns.
3Device complexity
If traditional paging messages are used without secondary identifier values, then message simplicity is maintained, but instruction delivery capability is limited
Solution Approach 1:
The patent makes the paging message structure multi-functional by incorporating secondary identifier values that can represent different types of control instructions (traffic switching, cell reselection, measurement configuration, etc.). The same basic message format can convey multiple different control meanings depending on which identifier values are present, eliminating the need for multiple specialized message types while maintaining structural simplicity.
Solution Approach 2:
The patent nests additional identifier values within the existing paging message structure. The secondary identifiers are embedded as additional fields or encoded elements within the conventional message framework, allowing the system to convey complex control information without fundamentally changing or complicating the base message structure. This nested approach preserves simplicity while expanding capability.

AI summary
Methods and apparatuses are disclosed for controlling communications devices. An access node can generate a message for at least one communication device for transmission at a resource determined at least partly on the basis of a first identifier value assigned to said at least one communication device. The generation comprises including in the message at least one other identifier value, wherein the other identifier values are assigned to communication devices for a purpose of addressing messages to communication devices. The at least one other identifier value is used exclusively for said at least one communication device at said resource and is recognisable to said at least one communication device as instruction to take one or more actions associated with the at least one other identifier value. A communication device can check for a message at the resource, the checking comprising checking in the message for the one or more other identifier values. In response to detecting one or more of said one or more other identifier values, said communication device can take one or more actions associated with said detected one or more of said one or more other identifier values.
