Service-Configured UE Access for Inactive Direct Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, multiple UEs attempting to access the same cell can cause interference and network overload, leading to congestion, resource waste, QoS degradation, and potential service unavailability, necessitating effective access control mechanisms, especially during inactive direct transmissions.
Innovation Solution
Implementing access control systems that allow UEs to perform direct data transmissions in an INACTIVE state without transitioning to the CONNECTED state by using service configuration signals and access control parameters, including backoff mechanisms and RACH procedures, to manage UE access attempts and network load.

Engineering Contradiction Analysis
1Productivity
If multiple UEs attempt to access the same cell simultaneously, then data transmission opportunities increase, but signal interference and network overload occur
Solution Approach 1:
The system performs preliminary actions by evaluating access control parameters and determining allowed direct transmissions before UE access attempts are processed. The network evaluates whether a UE is allowed to perform direct transmission based on pre-configured parameters, and the UE evaluates whether it should attempt direct transmission based on access control information, thereby preventing harmful interference and overload before they occur.
2Reliability
If access control mechanisms are implemented to limit UE access attempts, then network overload and congestion are reduced, but access control complexity increases
Solution Approach 1:
The access control mechanism is segmented into separate evaluation components: network-side evaluation of direct transmission allowance based on service configuration signals, and UE-side evaluation of access permission based on access control parameters. This segmentation distributes the complexity and enables independent optimization of each component's logic.
Solution Approach 2:
The system uses parameter changes by evaluating access control parameters and service configuration signals to dynamically determine allowed direct transmissions. The network and UE exchange parameter-based information (such as access control information, service configuration signals) that enables flexible access control without requiring complex procedural overhead.
3Reliability
If UEs transition to CONNECTED state for data transmission, then transmission reliability improves, but network resources and time are consumed
Solution Approach 1:
The system extracts the essential function of reliable data transmission from the full CONNECTED state transition process. By enabling direct transmissions in INACTIVE state for UEs that meet access control criteria, the system separates the reliability function from the state transition overhead, allowing UEs to transmit data reliably without always transitioning to CONNECTED state.
Data Source
AI summary
A user equipment (UE) associated with a wireless communication system is disclosed. The UE comprises one or more processors configured to process a service configuration signal received from a base station associated therewith. In some aspects, the service configuration signal comprises an indication of one or more service configurations associated with a data transmission that are allowed to be transmitted by the UE during an INACTIVE state of the UE. The one or more processors is further configured to determine the one or more service configurations associated with the data transmission that are allowed to be transmitted by the UE during the INACTIVE state of the UE, based on processing the service configuration signal.
