Group Communication Network Resource Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Group communication systems face challenges with latency, cost inefficiencies, and security/priority concerns due to the centralized control of network resources, especially in widely dispersed groups, which do not adequately account for geographical location, network load, and security/priority status.
Innovation Solution
Implementing a method to allocate network resources based on call control decision rules that consider parameters such as location, cost, network load, and security/priority status, using a parameter weighting system to optimize resource allocation and distribute control across multiple communication manager servers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If network resources are controlled by the communication manager server closest to the call initiator, then call setup is simplified, but latency increases due to long haul links
Solution Approach 1:
The patent segments the network into multiple service regions, each with its own communication manager server. Instead of having a single centralized controller, the system divides control functions across multiple regional servers. This segmentation allows calls to be controlled by local servers rather than requiring long-haul connections to a distant central server, thereby reducing latency while maintaining manageable complexity through modular regional control.
Solution Approach 2:
The patent implements local quality by allocating network resources based on the geographical location of group members. Calls are controlled by communication manager servers located in the same service region as the majority of participants, ensuring that control functions are performed locally rather than remotely. This local control reduces the need for long-haul links and minimizes call latency while keeping the system complexity manageable through regional autonomy.
2Device complexity
If network resources are allocated based on initiator proximity, then resource allocation is simple, but call costs increase due to long haul links
Solution Approach 1:
The patent applies local quality by allocating network resources according to the geographical distribution of group members. The system identifies which service region contains the majority of participants and allocates resources locally within that region. This approach replaces long-haul links with shorter local connections, reducing communication costs while maintaining simple allocation rules based on service region membership rather than complex real-time optimization.
Solution Approach 2:
The patent segments the network into cost-efficient service regions and allocates resources within each segment independently. By dividing the network into manageable regional segments with local communication managers, the system reduces the need for expensive long-haul links while keeping resource allocation logic simple through region-based rules rather than complex global optimization.
3Device complexity
If control is centralized at the initiator's location, then call management is straightforward, but security and priority requirements are not met
Solution Approach 1:
The patent implements local quality by controlling calls through communication manager servers located in the service region where the majority of group members are located. This local control mechanism ensures that calls are managed by servers that are geographically close to participants, reducing latency and costs. Simultaneously, the system maintains straightforward call management by using simple region-based control rules while meeting security and priority requirements through the decentralized architecture that allows appropriate servers to handle sensitive calls locally.
4Device complexity
If a single communication manager server controls the call, then resource allocation is simple, but network load is not optimized
Solution Approach 1:
The patent segments the control function across multiple communication manager servers distributed throughout the network, each responsible for a specific service region. This segmentation allows the system to maintain simple control architecture within each region while achieving network-wide load optimization. Calls are handled by local servers rather than being concentrated on a single server, distributing the network load efficiently across multiple nodes and improving overall network productivity.
Solution Approach 2:
The patent applies local quality by having each service region's communication manager server handle calls locally rather than centralizing control. This distributes the processing load across multiple local servers throughout the network, optimizing network efficiency by preventing any single server from becoming a bottleneck while maintaining simple local control logic at each server.

AI summary
Methods, devices, apparatus, computer-readable media and processors are provided for allocating network resources in a group communication system based on one or more call control rules. Call control rules may utilize one or more call control decision parameters including, but not limited to, the location of the group call members, the cost of the communication link and/or network resource options, the network load of the communication link options and the security status and/or priority status of the group call and/or the group call members. By basing allocation of the network resources on one or more of the call control decision parameters, the group communication call may experience improved latency and call cost, and/or may be assigned the requisite call security and/or call priority.
