Caller ID Delivery via SMS for Mobile Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Certain mobile devices on wireless networks cannot receive CNAM caller ID display text information due to limitations in carrier network mobile switching centers and other communication facilities, such as SDB/CDMA networks, and GSM networks, which restrict the provision of CNAM query results during call processing.
Innovation Solution
The solution involves delivering CNAM query results from a traditional CNAM service to a mobile handset via a Short Message Service (SMS) channel on a mobile carrier network, where a caller name query is performed and the result is sent to the recipient device via an SMS message before initiating the call, using a Short Message Service Center (SMSC) and Line Information Database (LIDB) to obtain caller identification information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If CNAM query results are delivered via traditional call page, then caller ID information can be provided, but mobile devices without CNAM capability or networks without CNAM transport cannot receive the information
Solution Approach 1:
The patent uses SMS as an intermediary communication channel to deliver CNAM query results. Instead of relying on the traditional call page mechanism that requires CNAM transport capability, the system sends caller ID information via SMS messages which can be received by any mobile device regardless of CNAM capability or network type, thus resolving the compatibility issue while maintaining reliable delivery
2Loss of information
If CNAM query is performed during call processing, then caller name information is obtained, but the information cannot be delivered to devices with communication facility limitations
Solution Approach 1:
The patent changes the delivery parameter from traditional call page (which requires CNAM transport capability) to SMS messaging (which has universal compatibility). By performing the CNAM query during call processing to obtain the information, then delivering it via SMS with a different transmission parameter, the system overcomes the communication facility limitations while ensuring information reaches all devices
3Productivity
If SDB/DOS or traditional call page is used for caller ID delivery, then information can be sent, but these facilities are unavailable or limited on certain networks after call page is sent
Solution Approach 1:
The patent ensures continuous delivery capability by using SMS as the communication channel. Unlike SDB/DOS or traditional call page methods that become unavailable after the call page is sent, SMS provides a continuous and reliable messaging channel that operates independently of call processing state, ensuring caller ID information can always be delivered regardless of network limitations

AI summary
Caller name (CNAM) query results obtained from a traditional CNAM service are sent during call processing on a carrier network to the subscriber's mobile handset over a Short Message Service (SMS) channel on a mobile carrier network. A call page is received at a network carrier associated with a recipient of the received call page. A caller name (CNAM) query is performed, and the result of the performed CNAM query is sent to the recipient device before sending the call page to the recipient device. The CNAM query result is displayed on a display of the recipient device.
