Cellular Network Status-Dependent Mobile Service Filtering

Solution Overview

Problem

In cellular networks, mobile devices (UE) frequently transition between idle and connected modes to handle location updates and queries, leading to unnecessary battery consumption, especially in machine-to-machine (M2M) communications where queries may not require immediate responses, and current mechanisms lack power-saving considerations.

Innovation Solution

A mechanism where the mobile node informs the cellular network of its status through special information in tracking area update messages, allowing the network to determine if it can process specific services, thereby avoiding data delivery when the UE is not capable, and implementing a QoS check for uplink data to manage resource usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the mobile device constantly transitions from idle mode to connected mode to update location status and respond to queries, then the network can maintain up-to-date presence information, but the battery power is wasted

Engineering Contradiction:

Improvepresence information accuracyVSAvoidbattery power consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The network performs preliminary actions by proactively determining service capability status and pre-configuring filtering rules before data packets arrive. The network node checks whether the mobile device is capable of processing specific services in advance and configures packet filtering accordingly, so that when data packets arrive, the mobile device does not need to wake up from idle mode to process them.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The network node acts as an intermediary between the server and the mobile device. It intercepts data packets from the server, determines whether the mobile device is capable of processing the service based on pre-configured rules, and filters out packets for services the mobile device cannot handle. This intermediary filtering prevents unnecessary wake-ups while maintaining accurate presence information for services the mobile device can process.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If the network delivers data packets to the mobile device without checking service capability, then data delivery is simple, but network and mobile device resources are wasted

AI summary

The present invention introduces system, apparatus and method that reduce wastage of network resources and mobile phone resources. The mobile phone would indicate its status in a tracking area update message when it is connected to the device. The network can then understand from the status indication that the mobile phone is capable of delivering packets to the device, and would thus allow the server to initiate communications. An absence of the status indication would imply the mobile phone is not capable of delivering packets to the device, and the network would then disallow the server to initiate communications.
