DTS Server MPS Token Management for Priority Data Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mechanisms for providing multimedia priority services (MPS) lack a prioritized data transport mechanism, leading to resource consumption and poor handling of emergency events due to the absence of such a mechanism.
Innovation Solution
A network device, the DTS server, provides prioritization for data transport services by generating and validating MPS tokens, managing MPS profiles, and allocating resources to support priority sessions for MPS subscribers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current mechanisms for providing multimedia priority services are used, then priority subscribers can make priority calls, but resource consumption increases and emergency events are poorly handled due to lack of prioritized data transport mechanism
Solution Approach 1:
The system performs preliminary actions by pre-establishing MPS profiles, tokens, and resource allocations before emergency events occur. The DTS server pre-validates subscriber eligibility, pre-allocates network resources, and pre-configures priority routing paths, enabling rapid response when emergency events actually happen without consuming resources on every individual event handling.
Solution Approach 2:
The DTS server acts as an intermediary between priority subscribers and the network infrastructure. It mediates by validating MPS tokens, managing profiles, and coordinating resource allocation across multiple network elements (RAN, EPC, IMS), thereby optimizing resource consumption while ensuring reliable emergency service delivery through centralized control.
2Loss of energy
If prioritized data transport mechanism is implemented, then resource consumption is conserved, but system complexity increases due to need for MPS token generation, validation, and profile management
Solution Approach 1:
The DTS server performs multiple functions within a single system component: generating MPS tokens, validating tokens, creating and managing MPS profiles, allocating resources, and coordinating priority data transport across RAN, EPC, and IMS. This multi-functionality consolidates what would otherwise require multiple separate systems into one unified platform, reducing overall system complexity while conserving resources.
Solution Approach 2:
The system implements self-service mechanisms where the DTS server automatically validates MPS tokens against stored profiles, autonomously allocates resources based on token validity, and dynamically manages priority bearers without requiring manual intervention. This automation reduces operational complexity and enables efficient resource conservation through programmatic control.

AI summary
A network device may receive a subscription request to subscribe to a multimedia priority service (MPS) for a user device, and may generate an MPS profile for the user device based on the subscription request. The network device may store the MPS profile in a data structure, and may receive, from the user device, a request to generate an MPS token for the user device. The network device may retrieve the MPS profile from the data structure based on the request to generate the MPS token, and may generate the MPS token based on the MPS profile. The network device may provide the MPS token to the user device.
