Power Mode Aware Packet Communication Service Table
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional power-saving modes in communication devices lack control over packet disposition and alert mechanisms, leading to inefficiencies such as delivering unwanted packets and unnecessary power consumption, as they do not consider the specific power modes of receiving terminals.
Innovation Solution
A method and apparatus for packet communication that processes packets based on a service table indexed by packet classification and the power mode of receiving terminals, allowing for controlled delivery and alerting, thereby optimizing power saving and communication efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If packets are buffered for later delivery during power-saving mode, then power consumption is reduced, but communication efficiency deteriorates due to lack of control over packet disposition
Solution Approach 1:
The patent implements dynamic packet handling by allowing the terminal to flexibly control packet disposition based on current power mode and packet priority. The system transitions from static buffering to dynamic decision-making where packets can be delivered, discarded, or buffered according to real-time conditions, resolving the contradiction between power saving and communication efficiency.
Solution Approach 2:
The patent changes the parameter of packet disposition control from fixed system-wide settings to variable terminal-controlled decisions. By allowing terminals to adjust packet handling parameters based on their power mode and service requirements, the system achieves both power efficiency and communication effectiveness simultaneously.
2Reliability
If all packets arriving during power-saving mode trigger alerts, then no important packets are missed, but power consumption increases due to unnecessary wake-ups
Solution Approach 1:
The patent applies local quality by differentiating alert behavior based on packet type and terminal state. Instead of uniform alerting for all packets, the system selectively triggers alerts only for high-priority packets or specific service types, allowing terminals to maintain reliability for important communications while avoiding unnecessary wake-ups for low-priority traffic.
Solution Approach 2:
The patent creates a virtual copy of the alert mechanism that operates in two modes: a selective alerting path for high-priority packets and a suppressed path for low-priority packets. This copying approach allows the system to maintain the capability for reliable delivery when needed while consuming minimal power during normal operation.
3Loss of information
If all packets are delivered regardless of terminal interest, then no useful information is lost, but network bandwidth is wasted on unwanted packets
Solution Approach 1:
The patent implements preliminary action by having terminals pre-configure their packet filtering preferences and priority classifications before receiving packets. The network uses these pre-configured parameters to selectively deliver only relevant packets, preventing bandwidth waste while ensuring no important information is lost. This advance preparation eliminates the need for post-delivery filtering.
4Device complexity
If conventional power-saving modes are used without terminal control, then implementation is simple, but service quality deteriorates due to inability to differentiate packet importance
Solution Approach 1:
The patent achieves universality by designing a packet handling framework that can accommodate multiple service types and priority levels within a single unified structure. The terminal-controlled mechanism works across different power modes, packet types, and service requirements without requiring separate implementations, maintaining simplicity while dramatically improving service quality.

AI summary
Packet communication method and system in which a packet destined for a terminal is provided service according to a service table indexed by packet classification and the terminal's power mode. The service table may specify for a connection a predetermined quality of service or discarding the packet. For a power mode having an alerting (i.e., paging) mechanism, the service may include alerting the terminal. The service table may also include a network edge point's own service requests and service requests from terminals, provisioning servers, and handoff sources. For a multicast or broadcast packet, as each terminal may be in a different power mode, the associated service in the service table may therefore be different for each terminal. In that case, the packet is provided with service so that any given terminal is provided with at least the quality of service specified in the service table. Thus, a multicast or broadcast packet is discarded when the service specified for all terminals is “discard.” Each terminal is alerted, however, if the associated service includes alerting the terminal. During handoff, a part of service table associated with the terminal can be transferred from the handoff source to the handoff destination.
