SIP Device Display_ID Parameter for Contact Details
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional SIP Enabled Devices do not effectively associate independent destination information with Direct Inward Dial (DID) or non-DID/private numbers, limiting the display of specific location and contact details to users during communication sessions.
Innovation Solution
Introduction of a Display_ID parameter, an alphanumeric data word stored locally on SIP Enabled Devices, which includes non-DID telephone numbers and location information, allowing additional user information to be displayed independently of SIP URI host address/user information, and included in communication session requests.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional SIP Enabled Devices display only SIP URI host address/user information, then data routing functionality is maintained, but specific location and contact details cannot be displayed to users
Solution Approach 1:
The patent segments the device information into two distinct parts: the traditional SIP URI (for routing) and the new Display_ID parameter (for display). This segmentation allows the SIP URI to maintain its routing functionality while the Display_ID provides additional location and contact details, resolving the contradiction between information completeness and data structure simplicity.
Solution Approach 2:
The Display_ID parameter acts as an intermediary between the SIP URI data and the user interface. It mediates by carrying additional display information (location, contact details) without interfering with the SIP URI's routing function, thus enabling rich information display while maintaining existing routing capabilities.
2Loss of information
If Display_ID parameter is added to communication session requests, then user information display is enhanced, but communication protocol data volume increases
Solution Approach 1:
The patent introduces a new parameter (Display_ID) to the existing SIP communication protocol. This parameter change enables additional user information to be transmitted without fundamentally altering the protocol structure. The Display_ID is formatted as an alphanumeric string that can be efficiently processed and transmitted, minimizing the impact on protocol data volume while maximizing information delivery.
Data Source
AI summary
An object of the invention is to associate a DID/public or non-DID/private telephone number and/or reachable location information with a SIP Enabled Device. More specifically, an embodiment of the invention is directed to providing an additional data parameter comprising alphanumeric data, as a “Display_ID” parameter. The parameter includes information including a DID/public telephone number non-DID/private number and/or location information that is specific to the SIP user endpoint and is different from the SIP URI host address/user information (terminal name and/or terminal number). In another embodiment, a first SIP Enabled Device accesses the local Display_ID and includes the Display_ID in a communication request. A second SIP Enabled Device is capable of processing the incoming communication request, extracting the Display_ID parameter, and displaying the Display_ID associated with the first SIP Enabled Device on the text display of the second SIP Enabled Device.
