Cellular CDN Identification Using IMSI Format for Wireless Content Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is no standardized protocol for wireless communications between Content Delivery Networks (CDNs) and other nodes in cellular telecommunication networks, leading to the use of proprietary IP-based protocols, which is undesirable.
Innovation Solution
Utilizing the International Mobile Subscriber Identifier (IMSI) format used for identifying User Equipment (UE) to also identify CDNs, allowing standardized wireless communications and data transfer processes, including storage and retrieval of content items, within cellular telecommunications networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If proprietary IP-based protocols are used for wireless CDN communications, then wireless connectivity is achieved, but device complexity and cost increase
Solution Approach 1:
The patent applies universality by making the CDN server identifier format compatible with the UE identifier format (IMSI). This allows the same identifier structure to serve dual purposes: identifying user equipment and identifying CDN servers. By using the universal IMSI format for CDN identification, the system avoids creating a separate proprietary identification protocol, thereby reducing device complexity while maintaining wireless communication capability.
2Loss of time
If CDNs are deployed on mobile access nodes with wireless backhaul, then content delivery latency is reduced, but standardized communication protocols are lacking
Solution Approach 1:
The patent makes the CDN server identifier format universal by using the IMSI structure. This allows mobile access nodes to communicate with CDN servers using standardized cellular network protocols rather than proprietary protocols, thereby achieving low-latency content delivery through wireless backhaul while maintaining protocol standardization.
Solution Approach 2:
The patent changes the identifier parameter format to match the IMSI structure. By configuring the CDN server identifier to follow the same format rules as UE identifiers (including the same digit structure and encoding), the system enables standardized protocol usage while supporting wireless CDN deployment for improved content delivery latency.
3Adaptability or versatility
If dedicated radio links with proprietary protocols are used, then wireless CDN connectivity is established, but capital costs increase
Solution Approach 1:
The patent reduces capital costs by making CDN identification universal with the IMSI format. This allows existing cellular network hardware and protocol stacks to be reused for CDN communications, eliminating the need for separate proprietary protocol implementations and dedicated radio link infrastructure, thereby reducing deployment costs while enabling wireless CDN connectivity.
