Voice Mail eCNAM Envelope Storage for Caller Trust
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing voice mail systems do not provide enhanced calling name (eCNAM) information when a call is missed or rejected by the user equipment (UE) or when paging is unsuccessful, limiting the user's ability to retrieve trust levels and analytic data for caller IDs.
Innovation Solution
A method is introduced where a network determines to use a voice mail associated with a call based on missed or rejected calls by the UE or unsuccessful paging. The network stores enhanced calling name (eCNAM) related envelope information, including caller identity analytic data, caller ID, trust level, and timestamp for the voice mail, and transmits this information to the UE along with the voice mail.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the network does not store eCNAM envelope information for missed or rejected calls, then the system complexity is reduced, but the user cannot retrieve trust levels and analytic data for caller IDs when checking voice mails
Solution Approach 1:
The network stores eCNAM envelope information (including caller identity analytic data, trust level, and timestamp) in advance for missed or rejected calls before the user requests it. This preliminary storage action ensures that when the user checks voice mail later, the eCNAM information is already available without requiring real-time retrieval or complex on-demand processing.
2Ease of operation
If the network transmits eCNAM envelope information with every voice mail, then the user experience is improved, but the data transmission volume and network load increase
Solution Approach 1:
The patent extracts only the essential eCNAM envelope information (caller identity analytic data, trust level, and timestamp) needed for user decision-making, rather than transmitting complete caller profile data. This selective extraction reduces data transmission volume while still providing users with sufficient information to evaluate incoming calls.
3Reliability
If the network stores detailed eCNAM analytic data for all calls, then the user can make informed decisions about caller trust, but the storage requirements and processing complexity increase
Solution Approach 1:
The network creates and stores simplified copies of eCNAM analytic data (trust level indicators and key analytic results) rather than maintaining complete raw analysis datasets. These copied envelope information records provide users with reliable trust verification capabilities while significantly reducing storage requirements and processing complexity compared to storing full analytic datasets.

AI summary
A method and apparatus for enhanced voice mail envelope information using enhanced calling name (eCNAM) and caller identity analytic functions in a wireless communication system is provided. A network determines to use a voice mail associated with a call based on a determination that the call is missed or rejected by a user equipment (UE) or a paging is unsuccessful, and stores enhanced calling name (eCNAM) related envelope information for the voice mail. The eCNAM related envelope information includes (i) a caller identity analytic data for the call, (ii) a caller identifier (ID) for the call, (iii) a trust level of the caller ID, and (iv) a time stamp for the voice mail. The network transmits, to the UE, the voice mail and the eCNAM related envelope information.
