Bearer Service Management for Repetitive Data Transfers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication networks face inefficiencies in handling repetitive data transfers, particularly for small amounts of machine-generated data, due to high signalling overhead and resource wastage, with existing radio access bearers either consuming excessive resources or failing to guarantee timely delivery.
Innovation Solution
A network node with additional bearer service attributes for handling repetitive data transfers, allowing for the deactivation and reactivation of bearers based on predefined time intervals and data amounts, minimizing signalling overhead and optimizing resource usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a new radio access bearer (RAB) is established for each transfer event of small amounts of machine-generated data, then the data transfer can be performed timely and reliably, but the signalling overhead becomes un-proportionally high and network resources are wasted
Solution Approach 1:
The patent applies preliminary action by establishing a single RAB in advance for repetitive data transfers instead of creating new bearers for each transfer event. The RAB is configured with parameters such as time intervals between transfers and data amounts, allowing the system to prepare the communication path beforehand. This eliminates the need for repeated bearer establishment and release signalling, thereby reducing signalling overhead while maintaining reliable data transfer capability for machine-generated data
Solution Approach 2:
The patent makes the RAB multi-functional by enabling it to handle multiple repetitive transfer events with different data amounts and time intervals. The bearer service attributes are made variable to accommodate different transfer patterns, allowing a single RAB configuration to serve multiple transfer requirements. This universal approach replaces the need for multiple dedicated bearers, reducing overall signalling overhead while maintaining timely and reliable data transfer
2Reliability
If a radio access bearer (RAB) is established indefinitely to handle repetitive transfers, then network resources are always available for timely data transfer, but network resources are unnecessarily occupied when no data needs to be sent
Solution Approach 1:
The patent applies dynamics by making the RAB configuration adaptable and variable rather than static and fixed. The bearer service attributes including time intervals between transfers and data amounts are configured dynamically based on actual transfer requirements. This allows the system to optimize resource occupation by adjusting RAB parameters to match the actual repetitive transfer patterns, ensuring resources are available when needed while avoiding unnecessary occupation during idle periods
Solution Approach 2:
The patent changes parameters by introducing variable bearer service attributes such as time intervals between transfers and data amounts for each transfer event. These parameters allow the RAB to be configured specifically for repetitive transfer patterns rather than maintaining a fixed indefinite configuration. By adjusting these parameters, the system can guarantee resource availability for timely transfers while optimizing the quantity of occupied network resources to match actual usage patterns
3Quantity of substance
If an interactive RAB is set up to go to inactive state when no data to transfer, then network resources are released, but there is no way to guarantee access to network resources when data needs to be transferred
Solution Approach 1:
The patent applies preliminary action by pre-configuring the RAB with specific bearer service attributes that define the repetitive transfer pattern including time intervals and data amounts. This preliminary configuration allows the system to predict when data transfers will occur and prepare accordingly. The RAB is set up in advance with knowledge of future transfer requirements, enabling the system to guarantee resource availability at the precise moments when transfers are needed while releasing resources during predictable idle intervals

AI summary
The present invention relates to a network node supporting communication of information and comprising bearer service handling means supporting one or more bearer services, each defined by a number of attributes, and bearer service managing means for controlling enablement, modification and maintenance of bearer services with particular QoSs, resource handling means adapted to distribute resources between bearer services information, attribute handling means adapted to handle attributes QoS profile for one or more of traffic classes and admission control means adapted to control bearer service resource allocation. The managing means are adapted to handle a first additional bearer service attribute comprising information about a time period between at least two consecutive information transfer events and a second additional bearer service attribute comprising information relating to the amount of data to be transferred during at least one of said at least two consecutive information transfer events. The managing means are adapted to activate a bearer service adapted to handle repetitive information transfer at a first transfer event, to provide for deactivation of an activated repetitive bearer service when a respective information transfer events ends and reactivation of the respective bearer service resources at, initiation of a subsequent information transfer event.
