3G to VoLTE Roaming Translator System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
User equipment (UE) faces challenges when traveling from a 3G network to an LTE network, as the visited network may not be configured for the same standard, requiring a new SIM and limiting seamless communication across different mobile networking standards.
Innovation Solution
A system that includes an evolved packet core (EPC) configured to proxy as an LTE-capable home public mobile network (HPMN) and a 3G mobile switching center (MSC) to proxy as a 3G-capable visited public mobile network (VPMN), with a translator to translate data, text, and voice communications between LTE and 3G standards, enabling LTE wireless communication and VoLTE roaming even without an IP multimedia subsystem (IMS) in the home network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a UE travels from a 3G network to an LTE network, then the UE can access newer technology, but the UE requires a new SIM and cannot communicate seamlessly
Solution Approach 1:
The patent introduces a roaming partner relationship between the 3G home network and LTE visited network, acting as an intermediary that enables the UE to access LTE services without requiring a new SIM. The visited network operator provides LTE access while the home network operator maintains 3G connectivity, bridging the compatibility gap through commercial and technical agreements.
2Productivity
If carriers operate on different communication standards, then each carrier can optimize its network, but seamless roaming between carriers is limited
Solution Approach 1:
The patent enables the UE to maintain multi-functionality by supporting both 3G and LTE standards simultaneously. The UE can selectively connect to 3G networks for home service and LTE networks for visited service, ensuring reliable roaming continuity across different communication standards without sacrificing network optimization capabilities.
3Reliability
If carriers establish direct partnerships for roaming, then seamless communication is achieved, but deployment time and complexity increase
Solution Approach 1:
The patent establishes pre-configured roaming agreements and technical frameworks between network operators before actual roaming is needed. By preparing roaming partnerships, inter-working protocols, and compatibility configurations in advance, the system enables rapid deployment when UEs need to roam between 3G and LTE networks, reducing both time and complexity.

AI summary
A 3G/LTE proxy system may enable LTE wireless communication by a UE roaming in an LTE VPMN but associated with a 3G carrier. The system may include an EPC configured to proxy as an LTE-capable HPMN for the UE as the UE is attached to a VPLMN. The system may include a 3G MSC configured to proxy as a 3G-capable VPMN for the HPMN. The system may include a translator. The translator may be configured to translate a data communication from an LTE data standard to a 3G data standard, and vice versa. The translator may be configured to translate a text communication from an LTE text standard to a 3G text standard, and vice versa. The translator may be configured to translate a voice communication from an LTE voice standard to a 3G voice standard, and vice versa.
