WLAN Caller ID Display via Mobile Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for displaying caller ID on a TV screen, such as those using IMS networks, require new network nodes and are not widely accessible due to the scarcity of IMS-enabled consumer equipment.
Innovation Solution
A method for a mobile communication device with a contacts database to wirelessly receive and process incoming caller information, determining if additional data is available in the database, and sending this information over a wireless local network to a displaying device, such as a TV, without the need for centralized storage, using standardized file formats like JPEG and communication protocols like DLNA and UPnP.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If IMS network architecture is used to display caller ID on TV screen, then caller ID display functionality is enabled, but device complexity and network infrastructure requirements increase
Solution Approach 1:
The patent extracts the caller ID information processing functionality from the centralized IMS network infrastructure and relocates it to the user's mobile device. The mobile device independently retrieves caller information from its own contacts database and transmits it via WLAN to the TV, eliminating the need for complex IMS network nodes and service broker functions.
Solution Approach 2:
The patent introduces a WLAN network as an intermediary communication channel between the mobile device and the TV. This simple wireless local area network serves as a mediator to transfer caller ID information without requiring the complex IMS network infrastructure, making the system more accessible to ordinary consumers.
2Adaptability or versatility
If centralized HSS database is used to store caller information, then caller ID service is enabled, but system complexity and cost increase
Solution Approach 1:
The patent extracts the caller information storage function from the centralized HSS (Home Subscriber Server) database and places it in the mobile device's local contacts database. This allows the system to use existing, simple database structures already present in mobile phones, eliminating the need for complex centralized database infrastructure.
Solution Approach 2:
The mobile device independently retrieves and processes caller information from its own contacts database without requiring external database queries or centralized service coordination. The device self-serves by having all necessary caller information locally available, simplifying the overall system architecture.
3Adaptability or versatility
If IMS-enabled equipment is deployed, then new functions are available, but accessibility to ordinary consumers is limited
Solution Approach 1:
The patent makes the mobile device universal by enabling it to perform multiple functions: it acts as both the caller ID information source (using its existing contacts database) and the communication initiator to the TV. This multi-functionality eliminates the need for specialized IMS-enabled equipment, allowing ordinary mobile phones to access the service.
Solution Approach 2:
The patent replaces expensive, specialized IMS network infrastructure with inexpensive, widely available components: a standard mobile device with WLAN capability and a TV with basic wireless reception. This substitution of cheap, accessible components for expensive infrastructure makes the service affordable and accessible to ordinary consumers.

AI summary
A method, a computer program, a computer program product and a user equipment (6) comprising a contacts database (16) and being connected to a telecommunications network (12) and to a displaying device (3) over a wireless local network (5). The method comprises the steps of: wirelessly receiving incoming caller information via the telecommunications network, determining based on the caller information, if there is additional information in the contacts database associated with the caller, determining if the local network is the same as a predefined network, and if the local network is the same as the predefined network perform the steps of: creating a message (19) comprising some of the received caller information and at least some of the additional information, sending the message to the displaying device to enable the displaying device to show the additional information comprised in the message.
