Wireless Device Local Address Roaming Location
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication devices face challenges in maintaining accurate signal transmission and reception while reducing power consumption, especially when roaming, due to the increasing demand for features and functionality, which can strain battery life and require precise location determination for service provision.
Innovation Solution
A wireless device connects to a WLAN access point while roaming and provides a local address to its home network, allowing the network to determine the device's location and decide on service provision, thereby reducing the need for explicit location determination and conserving battery life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the wireless device uses GPS or other explicit location determination methods to provide location information to the home network, then the home network can accurately determine the device's location for service provision, but the battery consumption and processing time increase significantly
Solution Approach 1:
The patent introduces the WLAN access point as an intermediary to convey location information. Instead of the UE directly determining and transmitting its location using power-intensive GPS, the UE's local address is transmitted through the WLAN access point, which the home network then uses to infer the UE's location. This intermediary approach significantly reduces the UE's power consumption while still enabling location-based service provision.
Solution Approach 2:
The patent replaces the mechanical/GPS-based location determination system with a network-based inference system. Instead of using hardware GPS receivers and complex location calculation algorithms in the UE, the system substitutes this with a simpler mechanism where the home network infers location from the local address provided through WLAN messaging. This substitution reduces the computational burden and power consumption in the UE.
2Adaptability or versatility
If the wireless device provides explicit location information to the home network, then the home network can determine whether to provide services based on location, but this requires user authorization and increases device complexity
Solution Approach 1:
The patent extracts the location determination function from the UE and relocates it to the home network. The UE only needs to provide its local address through standard WLAN messaging, while the home network performs the location inference and service provision decisions. This extraction simplifies the UE's complexity by removing the need for explicit location determination mechanisms and user authorization workflows in the device.
Solution Approach 2:
The home network performs self-service by autonomously determining the UE's location based on the local address and independently making service provision decisions. This eliminates the need for the UE to implement complex location sharing mechanisms or to request user authorization, as the home network handles the entire location-based service management process on its own.
3Reliability
If the wireless device maintains accurate signal transmission and reception capabilities while roaming, then communication quality is improved, but the increasing features and functionality place significant strain on battery life
Solution Approach 1:
The patent applies partial action by having the UE provide only its local address through WLAN messaging rather than implementing full location determination functionality. This partial information provision is sufficient for the home network to infer location and maintain communication quality, while avoiding the excessive power consumption associated with complete location determination and the continuous operation of additional features and functionality.

AI summary
This disclosure relates to providing local address information while roaming. A wireless device may connect to a wireless local area network (WLAN) access point in a roaming location. The wireless device may communicate with one or more servers of a home network via the WLAN access point. The wireless device may provide a local address of the wireless device to the home network in one or more messages related to a service. The home network may be configured to determine a location of the wireless device based on the local address and determine whether to provide the service based on the location of the wireless device. In response to the home network determining to provide the service based on the location of the wireless device, the wireless device may perform the service using the home network via the WLAN access point.
