UE Fast State Transition via Paging Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication networks face inefficiencies in transitioning between operating states by user equipment (UE) due to the need for extensive signaling and resource allocation, which consumes network resources and delays data transmission.
Innovation Solution
The technique involves sending configuration information over paging messages to allow UE to transition directly from a state like CELL_PCH to CELL_DCH without additional signaling, using pre-stored or default parameters to reduce overhead and latency, thereby enabling fast state transitions.

1Reliability
If the UE transitions between operating states using traditional signaling methods, then the state transition can be completed with proper resource allocation, but the process consumes excessive network resources and introduces delays
Solution Approach 1:
The network pre-configures the UE with configuration information for future state transitions while the UE is in idle state. This configuration is stored in the UE and activated immediately when needed, eliminating the need for time-consuming signaling exchanges during actual state transitions.
Solution Approach 2:
Configuration information acts as an intermediary that carries state transition parameters between the network and UE. Instead of direct signaling during state transition, the pre-configured information serves as a mediator that enables rapid state change without additional network communication.
2Reliability
If the UE transitions between operating states using traditional signaling methods, then the state transition can be completed with proper resource allocation, but extensive signaling is required which consumes network resources
Solution Approach 1:
The network sends configuration information to the UE in advance during idle state, so that when state transition is needed, the UE already has all necessary parameters stored locally. This eliminates the need for multiple signaling messages during active state transitions, reducing network resource consumption.
Solution Approach 2:
The UE uses pre-stored configuration information to autonomously perform state transitions without requiring continuous network signaling. The UE essentially serves itself by using previously received configuration data, reducing the burden on network resources.

AI summary
Techniques to support fast state transition by a user equipment (UE) are described. The UE may operate in a first state (e.g., a CELL_PCH state) in which the UE does not transmit or receive user data. The UE may receive a paging message carrying first configuration information. The UE may transition from the first state to a second state (e.g., a CELL_DCH state) in response to receiving the paging message. The UE may determine a set of communication parameters based on the first configuration information received from the paging message and second configuration information stored at the UE. The UE may then exchange user data based on the set of communication parameters. The UE may use default values for some parameters in order to reduce the amount of first configuration information to send in the paging message.
