UE Registration Retry Control for Failure Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems have inefficient or ineffective fixed time durations and quantities of registration retry attempts for user equipment (UE) during registration procedures, which can lead to suboptimal connection establishment.
Innovation Solution
The UE selects the duration and quantity of registration retry attempts based on observed conditions, such as type, battery status, network conditions, and user preferences, allowing flexible adaptation of retry strategies.

Engineering Contradiction Analysis
1Ease of manufacture
If fixed time durations and quantities of registration retry attempts are used, then the registration procedure is simple to implement, but the efficiency and effectiveness of registration is reduced
Solution Approach 1:
The patent implements dynamic retry parameters where the quantity of registration retry attempts and time durations are no longer fixed but adapt based on UE-specific conditions such as battery status, device type, and network conditions. This allows the system to optimize registration efficiency for different scenarios while maintaining implementation simplicity through standardized adaptation rules.
Solution Approach 2:
The patent changes the parameters of registration retry attempts from fixed values to variable values that depend on UE conditions. The quantity of retries and time durations are adjusted based on factors like battery level, device capabilities, and network state, thereby improving registration efficiency without significantly complicating the implementation through clear parameter adaptation criteria.
2Ease of operation
If fixed time durations and quantities of registration retry attempts are used, then the system is easy to manage, but it is ineffective for different UE conditions
Solution Approach 1:
The patent applies local quality by tailoring the registration retry parameters to specific UE conditions rather than using a uniform approach for all devices. Different UE types, battery statuses, and network conditions receive customized retry configurations, improving adaptability while maintaining system manageability through standardized rules for determining these localized parameters.
Solution Approach 2:
The UE autonomously determines its own retry parameters based on its internal conditions (battery status, device type) and observed network conditions, without requiring complex external configuration or management. This self-service approach enhances adaptability to individual UE conditions while keeping the system easy to manage by eliminating the need for centralized parameter distribution.
3Reliability
If the quantity of registration retry attempts is increased, then the connection success rate improves, but the resource consumption increases
Solution Approach 1:
The patent dynamically adjusts the quantity of registration retry attempts and associated time durations based on UE-specific parameters such as battery status, device type, and network conditions. This allows the system to increase retries when resources are abundant (improving connection success rate) while reducing retries when resources are constrained (conserving energy), thereby resolving the contradiction between reliability and energy loss.
Solution Approach 2:
The retry parameters are made dynamic rather than static, allowing the system to adapt the quantity of retry attempts to current UE conditions. When the UE has sufficient battery and good network conditions, more retries are permitted to improve connection success. When battery is low or conditions are poor, fewer retries are attempted to conserve resources, balancing reliability and energy consumption.
Data Source
AI summary
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a registration request to a network entity that requests registration of the UE on a wireless network associated with the network entity. The UE may detect a registration failure associated with the registration request, the registration failure being associated with a condition associated with the UE. The UE may transmit a set of registration request retry messages based at least in part on the registration failure, wherein at least one of a quantity of registration request retry messages in the set of registration request retry messages or a duration between transmissions within the set of registration request retry messages is based at least in part on the condition associated with the UE.
