Base Station Acknowledgment Signaling for Adaptive Service Timers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
User equipment in wireless communication systems often abandon service requests prematurely due to default guard timers expiring before the base station can complete the service, leading to unnecessary resource monopolization and increased latency.
Innovation Solution
Base stations dynamically adjust timer values by transmitting acknowledgments indicating either a default or extended time interval based on the availability of resources and configuration information, allowing user equipment to modify their timers accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If user equipment uses a default guard timer to wait for service completion, then the timer duration is short and resource monopolization is reduced, but the timer may expire before the base station can complete the service leading to unnecessary request abandonment
Solution Approach 1:
The patent applies dynamics by making the guard timer value adjustable rather than fixed. The base station dynamically determines an extended timer value based on current network conditions, service type, and resource availability, then communicates this extended value to the user equipment. This allows the timer to adapt between short default values (when service can be completed quickly) and longer extended values (when resource allocation or service setup takes more time), resolving the contradiction between minimizing time loss and ensuring reliable service completion.
Solution Approach 2:
The patent implements feedback by having the base station monitor its own service completion capability and resource status, then provide feedback to the user equipment about the appropriate guard timer value to use. The base station sends an extended guard timer value in response to a service request, creating a feedback loop that allows the timer duration to be optimized based on actual network conditions rather than using a static default value, thereby improving service completion reliability without excessive time loss.
2Reliability
If user equipment extends the guard timer to wait for service completion, then service completion reliability is improved, but resource monopolization increases and system efficiency decreases
Solution Approach 1:
The patent resolves this contradiction through dynamic timer adjustment where the guard timer is extended only when necessary. The base station evaluates whether service completion can be achieved within the default timer period and only communicates an extended timer value when additional time is actually needed for resource allocation or service setup. This dynamic approach ensures high service completion reliability while preventing unnecessary resource monopolization, as the timer is prolonged only in cases where the base station genuinely requires more time to fulfill the service request.
Solution Approach 2:
The patent applies parameter changes by modifying the guard timer value parameter based on network conditions and service requirements. Instead of using a fixed extended timer value for all cases, the base station adjusts the timer parameter dynamically - using default short values when service can be completed quickly and extended longer values only when resource allocation or service setup requires additional time. This parameter adaptation resolves the contradiction by optimizing both reliability and system efficiency under different operating conditions.
3Reliability
If base station retrieves data from another network entity to service the request, then service quality is improved, but the time required to complete the service exceeds the default timer interval
Solution Approach 1:
The patent applies preliminary action by having the base station proactively determine whether data retrieval from another network entity is needed before the user equipment's guard timer expires. The base station evaluates its ability to complete the service within the default timer period and, if external data retrieval is required, pre-communicates an extended timer value to the user equipment. This preliminary assessment and communication prevent premature request abandonment by ensuring the user equipment maintains its service request state long enough for the base station to complete necessary external data retrieval operations.
Solution Approach 2:
The base station acts as an intermediary that mediates between the user equipment's timing constraints and the external network entity's data availability. When the base station needs to retrieve data from another network entity, it uses the extended guard timer mechanism to bridge the time gap, communicating to the user equipment that additional time is required while the base station handles the external data retrieval. This intermediary role allows the system to maintain service quality through external data retrieval while managing the time loss through coordinated timer extension.

AI summary
A base station includes a receiver configured to receive, from a user equipment, a request to establish a service to the base station. The base station also includes a processor configured to determine, in response to receiving the request, whether the request is serviceable within a default time interval. The base station further includes a transmitter configured to transmit an acknowledgment comprising information indicating an extended time interval in response to the base station determining that the extended time interval is needed to successfully complete the request. The user equipment includes a receiver configured to receive the acknowledgment from the base station. The user equipment also includes a timer configured to start and run for a default time in response to transmission of the request. The timer is modified in response to receiving the information indicating the extended time interval.
