Multimode Device Network Identity and Time Zone Provisioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Multimode portable devices lack the capability to display accurate network identity and time zone information when transitioning between GSM/3GPP networks and non-3GPP networks, such as WLAN environments, leading to incorrect display of local time and network provider information.
Innovation Solution
The use of configuration protocols like SIP, NTP, DHCP, and SSID broadcast by wireless access points to determine and display the correct local time and network provider identity on multimode devices, ensuring accurate network identity and time zone information is displayed across different network technologies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multimode devices support multiple network technologies (GSM, 3GPP, non-3GPP), then network compatibility and service versatility improve, but the ability to accurately display network identity and time zone information deteriorates when transitioning between network types
Solution Approach 1:
The patent implements a universal configuration protocol handler that processes multiple configuration protocols (SIP, NTP, DHCP, SSID) across different network technologies. This multi-functional approach allows the device to maintain accurate network identity and time zone information regardless of whether it is connected to GSM, 3GPP, or non-3GPP networks, resolving the contradiction between network versatility and information accuracy.
2Adaptability or versatility
If the device transitions between different network types (GSM to non-3GPP), then service flexibility improves, but time zone information accuracy deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the configuration protocol handler continuously monitors network transitions and actively requests updated time zone information from the current network. When transitioning from GSM to non-3GPP networks, the system detects the network type change and triggers a new configuration protocol exchange to obtain accurate time zone data, ensuring time zone accuracy is maintained despite network flexibility.
3Loss of information
If the device uses multiple configuration protocols (SIP, NTP, DHCP, SSID), then information completeness improves, but system complexity increases
Solution Approach 1:
The patent merges multiple configuration protocol handlers (SIP, NTP, DHCP, SSID) into a single integrated configuration protocol handler component. This unified structure processes all configuration information through one coordinated system rather than four separate independent systems, reducing overall system complexity while maintaining complete information acquisition across all protocol types.
Data Source
AI summary
A system that provisions a multimode mobile or converged device with local time information and network provider identification when the multimode mobile device is operating within the purview of a wireless local area network (WLAN). The system includes components that receive protocol data and that extract network provider identification from the received protocol data as well as utilizing the received protocol data to ascertain the local time.
