Roaming User Equipment Home Network APN Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for availing data services during international roaming often result in delays due to intermittent APN setting installation, leading to poor user experience, as they rely on network availability and bilateral agreements between operators.
Innovation Solution
A method and system where user equipment, equipped with both home and global IMSI, automatically extracts IMPI to identify configuration parameters, including APN, and transmits these to the network for authentication, enabling immediate data service access without relying on foreign network APN settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the user equipment relies on foreign network APN settings during international roaming, then the device can access local network services, but data service availability is delayed due to intermittent APN setting installation
Solution Approach 1:
The user equipment pre-configures multiple APN settings including both home network APN and foreign network APN before international roaming. When roaming, the device can immediately use the pre-configured home network APN without waiting for network-provided APN settings, thus eliminating installation delays and ensuring immediate data service availability.
2Productivity
If the user equipment uses home network APN settings during international roaming, then data service access is immediate, but network authentication complexity increases
Solution Approach 1:
The user equipment acts as an intermediary by maintaining and managing multiple APN configurations locally. The device automatically selects and switches between home network APN and foreign network APN based on roaming status, simplifying the authentication process by handling the complexity of multiple network configurations internally without requiring complex user intervention or network coordination.
3Adaptability or versatility
If the user equipment relies on bilateral agreements between operators for roaming data services, then network interworking is simplified, but service availability is reduced due to network availability constraints
Solution Approach 1:
The user equipment dynamically changes the APN configuration parameter based on roaming status. When detecting international roaming, the device switches from using foreign network APN (which requires bilateral agreements and network availability) to using home network APN (which provides guaranteed service continuity). This parameter change enables the device to maintain reliable data service access regardless of foreign network availability or bilateral agreement status.

AI summary
The present disclosure encompasses a system and a method for availing a data service by a user equipment [110] in an international location. In an embodiment, the user equipment [110], in the international roaming, transmits an attach request to a second network, wherein the user equipment [110] configured with a SIM [120]. The user equipment [110] then receives a rejection message or an acceptance message from the second network based on the attach request. On receiving the acceptance message, the user equipment [110] establishes a connection with the second network to extract an IMPI from the SIM, an IMSI from the IMPI; and a network parameter from the IMSI. The user equipment [110] then identifies a configuration parameter of the home network, corresponding to the network parameter. Finally, the user equipment [110] avails the data service using the configuration parameter.
