Multipoint-to-Point EPS Bearer Clustering for Low Power IoT
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless communication systems for low power user equipments (UEs) consume excessive resources and maintain bearers in an 'ON' state even when not transmitting data, leading to inefficient energy use and resource utilization, particularly for low data size messages.
Innovation Solution
The implementation of a Multipoint-to-Point (MP2P) EPS bearer system in a packet switched transmission network, where multiple UEs are connected to a single eNodeB and S bearers, eliminating the need for individual bearers and packet inspection at the eNodeB and serving gateway, and activating only when data transmission is required.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional P2P EPS bearers are used for each UE, then each UE can establish individual connection, but network resources are consumed excessively and bearers cannot be switched OFF when not transmitting data
Solution Approach 1:
The patent merges multiple individual P2P EPS bearers into a single MP2P EPS bearer that serves multiple UEs simultaneously. This consolidation allows the network to maintain a single active bearer connection instead of multiple separate bearers, enabling the bearer to be switched OFF when not in use and significantly reducing energy consumption while maintaining reliable connection establishment for all UEs.
Solution Approach 2:
The MP2P EPS bearer is designed as a universal bearer that can serve multiple UEs with different purposes and QoS requirements through a single connection. This multi-functional bearer eliminates the need for separate dedicated bearers for each UE, allowing resource optimization and the ability to deactivate the bearer when no data transmission is required.
2Productivity
If conventional P2P EPS bearers are maintained in ON state, then data transmission can occur anytime, but surplus resources are consumed and bearers cannot be deactivated
Solution Approach 1:
The patent introduces dynamic state management for the MP2P EPS bearer, allowing it to transition between ON and OFF states based on actual data transmission requirements. This dynamic approach enables the bearer to be activated only when needed and deactivated when idle, optimizing resource utilization while maintaining the capability for timely data transmission when required.
Solution Approach 2:
The system changes the operational parameter of the bearer from a static ON state to a dynamic state that can be switched between ON and OFF based on traffic conditions. This parameter change allows the network to optimize bearer resource allocation by activating the bearer only when data transmission is required and deactivating it otherwise.
3Ease of operation
If packet inspection is performed at S1 bearer and serving gateway, then data routing can be controlled, but network complexity and processing overhead increase
Solution Approach 1:
The patent extracts and eliminates the packet inspection function from the S1 bearer and serving gateway by implementing a simplified routing mechanism where all UEs are clustered into a single group with a predefined destination. This extraction removes the complex packet inspection process while maintaining effective data routing control through the simplified group-based approach.
Solution Approach 2:
The solution implements a universal routing approach where a single MP2P EPS bearer serves all UEs in the cluster with a common destination, eliminating the need for individual packet inspection for each UE. This universal approach simplifies network processing while maintaining routing control through the grouped UE architecture.
4Productivity
If low data size messages are transmitted using conventional systems, then data can be sent, but bearers cannot be switched OFF and energy is wasted waiting for data accumulation
Solution Approach 1:
The patent merges multiple low data size message transmissions into a single MP2P EPS bearer connection, allowing small data packets from multiple UEs to be aggregated and transmitted efficiently. This consolidation enables the bearer to handle low data size messages without requiring separate dedicated bearers for each message, eliminating energy waste from maintaining multiple active bearers.
Solution Approach 2:
The system implements periodic data collection from UEs through the MP2P EPS bearer, allowing low data size messages to be transmitted at optimized intervals. This periodic action enables efficient data collection from multiple UEs while allowing the bearer to be deactivated between transmission cycles, preventing energy waste from continuous bearer maintenance.

AI summary
A method for creating a Multipoint-to-Point EPS bearer in a packet switched transmission network is envisaged. A plurality of user equipments are installed within a tracking area assigned to a serving gateway. The user equipments are communicably coupled to an eNodeB, which is configured to receive the uplink data packets transmitted from the user Equipments. The eNodeB is communicably coupled to an S1 bearer, and with the S1 bearer designated as the destination for every uplink data packet transmitted from the eNodeB, the need for packet inspection at the eNodeB is eliminated. Likewise, since the S1 bearer is the only possible intermediate destination for the downlink data packets originating from the serving gateway, the process of packet inspection is also absolved at the serving gateway. The Multipoint-to-Point EPS bearer is communicably coupled to the user equipments for transmission of both uplink data packets and downlink data packets without packet inspection.
