Call-Routing Number Management in Distributed Switching Clusters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing call-routing number management in mobile communication networks is inefficient due to the need for multiple call-routing number series, leading to over-dimensioning and resource wastage, especially in distributed switching systems where not all cluster members require the same number of series based on traffic profiles.
Innovation Solution
A data structure and method for managing call-routing numbers that associates cluster members with the least significant digits of a number series, allowing for flexible distribution and balancing of numbers among cluster members, eliminating the need for additional number series when adding new members or adjusting for capacity changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complete call-routing number series is assigned to each cluster member, then each cluster member can independently route calls, but the number of call-routing number series increases unnecessarily, leading to resource wastage
Solution Approach 1:
The patent segments the call-routing number series into portions and distributes them among multiple cluster members. Instead of assigning complete series to each cluster member, the system divides the series into segments that can be allocated based on actual traffic requirements, reducing the total number of series needed while maintaining routing capability.
Solution Approach 2:
The patent implements a universal call-routing number management mechanism that allows multiple cluster members to share common number series. The system enables any cluster member to handle calls routed through the shared series, providing multi-functionality that eliminates the need for dedicated complete series for each cluster member.
2Productivity
If additional cluster members are added to the switch cluster, then capacity and load balancing improve, but new call-routing number series must be configured, increasing network complexity
Solution Approach 1:
The patent implements dynamic call-routing number allocation that automatically adapts when cluster members are added or removed. The system dynamically adjusts the distribution of number series among cluster members based on current configuration, eliminating the need for manual reconfiguration of number series when cluster members change.
Solution Approach 2:
The patent enables the switch cluster to self-manage its call-routing number allocation. When new cluster members join or existing members leave, the system automatically redistributes number series without requiring external intervention or manual configuration, allowing the cluster to self-adjust to capacity changes.
3Ease of operation
If call-routing numbers are distributed uniformly among cluster members, then simplicity is maintained, but cluster members with lower traffic capacity are over-provisioned, wasting resources
Solution Approach 1:
The patent applies local quality by tailoring the allocation of call-routing number series to the specific traffic characteristics of each cluster member. Instead of uniform distribution, the system allocates number series proportionally based on each cluster member's actual traffic profile, ensuring that members with higher capacity receive more numbers while members with lower capacity receive fewer numbers appropriately.
Data Source
AI summary
A technique for managing call-routing numbers in a mobile communication network using a distributed switching system is provided. The switching system embodies a cluster configuration, wherein at least one cluster of the switching system comprises a plurality of cluster members, each of which is capable of routing an incoming call based on a call-routing number temporarily associated with the call. A defined series of call-routing numbers is distributed between the plurality of cluster members. The management technique makes use of a common data structure which defines an amount of assignments equal to the length of a given series of call-routing numbers, wherein each assignment uniquely associates a cluster member with one or more least significant digits of the numbers of the number series.
