Softphone App Linking Mobile Devices to Hotel PBX
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hotels face challenges in providing convenient and cost-effective communication services to guests, as landline telephones require maintenance and guests often prefer using their mobile phones, but mobile phones can be inconvenient and incur roaming charges, especially with poor indoor reception.
Innovation Solution
A system and method that allows guests to link their mobile devices to the hotel's PBX system using an app, enabling them to place and receive calls through the hotel's network, leveraging mobile telephony technologies like SIP and WiFi for connectivity, and activating/deactivating calling features based on registration and location information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If landline telephones are installed in every hotel room, then guests can conveniently contact the hotel, but the hotel incurs ongoing maintenance costs and servicing requirements
Solution Approach 1:
The patent creates a virtual copy of the landline telephone functionality by implementing a softphone application on guests' mobile devices. This software-based telephone client replicates the core calling functions without requiring physical hardware installation in each room, thereby eliminating maintenance costs while preserving ease of operation.
Solution Approach 2:
The patent replaces the mechanical landline telephone system with a software-based mobile application. By substituting the physical hardware (landline phones, wiring, switches) with a software solution running on guests' existing mobile devices, the system eliminates ongoing maintenance requirements while maintaining telecommunication functionality.
2Loss of energy
If guests use their mobile phones to contact the hotel, then maintenance costs are reduced, but guests incur roaming charges and experience poor indoor reception
Solution Approach 1:
The patent introduces the hotel's WiFi network as an intermediary communication channel. The softphone application utilizes the hotel's local WiFi infrastructure to establish voice and data connections, serving as a mediator between guests' mobile devices and the hotel's communication systems. This eliminates dependence on external cellular networks, thereby avoiding roaming charges and reception issues.
Solution Approach 2:
The patent makes the hotel's WiFi infrastructure multi-functional by using it not only for general internet access but also as the primary communication channel for telephony services. This universal utilization of the WiFi network allows guests to make calls and access hotel services without incurring additional roaming charges or being affected by cellular reception quality.
3Loss of energy
If a softphone application is deployed on guests' mobile devices, then hardware maintenance is eliminated, but the system complexity increases through software integration requirements
Solution Approach 1:
The patent implements automatic registration and configuration features where the softphone application autonomously discovers the hotel's communication servers, retrieves necessary configuration parameters, and establishes connections without requiring manual setup by hotel staff. This self-service capability significantly reduces the operational complexity despite the sophisticated underlying software integration.
Solution Approach 2:
The patent performs configuration and authentication actions in advance during the guest check-in process. The softphone application is pre-configured with hotel-specific parameters, and authentication credentials are provided before the guest begins using the service. This preliminary setup eliminates the need for complex real-time configuration and reduces perceived system complexity for end users.
4Reliability
If calling features are continuously activated for all guests, then service availability is maximized, but system security and resource management are compromised
Solution Approach 1:
The patent implements dynamic activation of calling features based on real-time guest status. The system automatically enables or disables telephony capabilities according to check-in/check-out events, room occupancy status, and authentication states. This dynamic approach ensures service availability is maintained for authorized guests while automatically revoking access when conditions change, thereby balancing reliability with security.
Solution Approach 2:
The patent employs feedback mechanisms where the system continuously monitors guest status, authentication states, and usage patterns. Based on this feedback, the system automatically adjusts service availability, enabling calling features when appropriate and disabling them when security concerns arise. This closed-loop control ensures both high availability for legitimate users and robust security against unauthorized access.
Data Source
AI summary
A method and system of providing telecommunication services for guests is disclosed. A guest's registration is received. An app on a mobile electronic device is linked to the registration. Calling features are activated based on the registration. The app on the mobile electronic device is connected to an external phone system so the mobile electronic device can be used to place and receive calls through the external phone system.
