Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current management techniques for converged fixed-access and radio-mobile telecommunications networks lead to inefficient allocation of optical resources, failing to optimize bandwidth and resource distribution between fixed-access and mobile-radio parts, particularly in FTTH architectures, which affects Quality of Service (QoS) and network performance.
Innovation Solution
A centralized management module that collects performance indicators from both fixed-access and radio-mobile parts to dynamically allocate optical, virtualized, and radio resources, optimizing resource allocation based on throughput requirements and user profiles, ensuring efficient data transfer and performance across the network.

Engineering Contradiction Analysis
1Productivity
If current independent management techniques are used for fixed-access and radio-mobile networks, then each network can be managed separately with existing protocols, but resource allocation becomes inefficient and QoS cannot be optimized across the converged network
Solution Approach 1:
The patent merges the management of fixed-access and radio-mobile networks into a unified centralized management system. The centralized management module collects performance indicators from both network types and allocates optical resources considering both fixed and mobile traffic requirements, thereby improving overall resource allocation efficiency while maintaining manageable complexity through automation.
Solution Approach 2:
The centralized management module serves multiple functions: it manages optical resources for both fixed-access and radio-mobile networks, collects performance indicators from diverse network elements, and makes unified allocation decisions. This multi-functional approach eliminates the need for separate management systems while improving cross-network resource optimization.
2Reliability
If optical resources are allocated using traditional DBA mechanisms without considering mobile network specificities, then fixed-access network requirements are met, but mobile user QoS and throughput requirements cannot be guaranteed
Solution Approach 1:
The system dynamically adjusts optical resource allocation based on real-time performance indicators from mobile networks. The centralized management module continuously monitors traffic conditions, base station configurations, and user requirements to adaptively allocate bandwidth, ensuring QoS guarantees for mobile users while maintaining flexibility in network configuration.
Solution Approach 2:
The patent implements a feedback mechanism where performance indicators from mobile networks (such as throughput, latency, and traffic patterns) are collected and used to adjust optical resource allocation. This closed-loop feedback ensures that QoS requirements are met while adapting to changing network conditions and user needs.
3Productivity
If fiber capacity between CUs and DUs is increased to support virtualized radio functions, then mobile network performance is improved, but optical network infrastructure requirements and costs increase
Solution Approach 1:
The system changes the allocation parameters of existing optical infrastructure rather than expanding physical infrastructure. By dynamically adjusting bandwidth allocation parameters based on actual mobile traffic demands and virtualized function requirements, the system achieves high throughput capacity utilization without proportionally increasing fiber infrastructure quantity.
Solution Approach 2:
Instead of provisioning full fiber capacity for all possible scenarios, the system allocates optical resources partially based on actual demand patterns and performance indicators. This allows the network to achieve sufficient capacity for virtualized functions while avoiding over-provisioning of optical infrastructure.

AI summary
The invention relates to a method for managing resources of a mobile radio and fixed access convergent telecommunications network, at least some of the resources being implemented in remote and virtualized form in the network, optical resources of the network being allocated between at least one optical router and a plurality of optical modems of the network. According to such a method, a module (110) for the centralized management of the mobile radio resources of the network performs the following: receiving (E210) a performance indicator from the mobile radio portion of the network, transmitted by at least one base station (lOOdu) of the network connected to one of the optical modems and/or by a module (100vran) for virtualized radio functions that are remote in the network; estimating (E211) requirements of the mobile radio portion of the network in terms of optical resources based on the performance indicator from the mobile radio portion, delivering information representative of the requirements in terms of optical resources; and transmitting (E212) the information representative of the requirements in terms of optical resources to a module (120) for the centralized management of the optical and fixed access resources of the network in order to manage the optical resources of the network.
