Emergency Service Identifier Network Resource Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network communication technologies with an independent bearer control layer fail to ensure unconditional admission and non-degraded Quality of Service (QoS) for emergency services, such as police, fire, and ambulance calls, leading to potential losses and accidents when network resources are insufficient.
Innovation Solution
A method is introduced where an emergency service identifier is sent to the network, allowing for immediate resource allocation from reserved or unoccupied resources, with the option to release lower-priority services if necessary, ensuring emergency services are prioritized and connected without QoS degradation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional Diff-Serv model with independent bearer control layer is used for network resource management, then network resource utilization is improved, but emergency services cannot be guaranteed unconditional admission when resources are insufficient
Solution Approach 1:
The patent establishes a reserved resource pool specifically for emergency services in advance, before resource contention occurs. This preliminary action ensures that when emergency services need admission, dedicated resources are already available, guaranteeing unconditional admission regardless of overall network resource utilization status.
Solution Approach 2:
The patent segments network resources into two distinct parts: a reserved resource pool for emergency services and a dynamic resource pool for normal services. This segmentation allows independent management of emergency resources, ensuring they are not consumed by non-emergency traffic while still achieving high overall resource utilization through efficient dynamic allocation.
2Productivity
If resource allocation follows normal service procedures, then resource distribution is optimized, but emergency services may experience QoS degradation or rejection
Solution Approach 1:
The system performs preliminary identification of emergency services through emergency service identifiers before resource allocation occurs. This early detection enables the network to apply special resource allocation procedures specifically for emergency services, ensuring they receive guaranteed resources and QoS treatment while normal services continue to receive optimized resource distribution.
Solution Approach 2:
The patent applies different resource allocation qualities to different service types: emergency services receive guaranteed, priority resource allocation from the reserved pool, while normal services receive optimized allocation from the dynamic pool. This local differentiation ensures emergency services get the reliability they need without compromising overall system efficiency.
3Productivity
If network resources are fully utilized for normal services, then resource efficiency is maximized, but emergency services lack available resources during congestion
Solution Approach 1:
The network resources are segmented into a reserved pool for emergency services and a dynamic pool for normal services. The reserved pool maintains a baseline level of resources dedicated to emergency services, ensuring their availability during congestion. The dynamic pool maximizes resource efficiency by allocating available resources to normal services based on current network conditions and service demands.
Solution Approach 2:
The system preliminarily reserves a portion of network resources for emergency services before normal service allocation occurs. This preliminary reservation ensures that even when network resources are fully utilized, a guaranteed portion remains available for emergency services, maintaining their availability while still achieving high overall resource efficiency through the dynamic pool.

AI summary
The present invention discloses a method for handling an emergency service in a network communication, including: sending, by an emergency service initiating side, an emergency service identifier together with an emergency service to a network side; and allocating, by the network side, resource to the emergency service with a priority higher than those of normal services. With the present invention, a corresponding emergency service may be identified effectively in a network provided with an independent bearer-control-layer entity, and a resource may be allocated to the emergency service in accordance with a special resource allocation policy. Therefore, it is possible to guarantee the connectivity and the resource for the emergency service as requested in the network, and hence to reduce an unexpected and unnecessary loss.
