Bootstrap Data Channel Setup for Interactive Call Services
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication technologies, such as those based on the Internet Protocol Multimedia System (IMS) networks, fail to support the establishment of interactive data channels that enable the transmission of diverse types of data, such as text, webpages, pictures, videos, and position information during voice and video calls, and lack clear specifications for triggering the bootstrap data channel establishment and network element cooperation.
Innovation Solution
A method for establishing an interactive bootstrap data channel in operator call networks, allowing terminals to initiate data channels with service platform media modules, enabling the transmission of richer data types, including text, webpages, pictures, videos, and position information, by integrating a bootstrap data channel with native call applications, and specifying network element cooperation for negotiation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional IMS network communication is used, then voice and video call functions are supported, but interactive data channel transmission (text, webpages, pictures, videos, position information) is not supported
Solution Approach 1:
The patent merges the voice/video call function with interactive data channel transmission by establishing a unified communication framework. The terminal device simultaneously maintains a voice/video call connection and a data channel connection with the same peer, allowing multiple data types (text, webpages, pictures, videos, position information) to be transmitted alongside audio/video streams through integrated protocol handling.
Solution Approach 2:
The communication system is enhanced to perform multiple functions: traditional voice calling, video calling, and interactive data transmission (text, webpages, pictures, videos, position information) all through the same communication infrastructure. The terminal device and service platform cooperate to provide a universal communication platform that handles diverse data types without requiring separate systems.
2Reliability
If bootstrap data channel establishment is integrated with native call applications, then end-to-end service implementation is enabled, but clear specifications for triggering and network element cooperation are required
Solution Approach 1:
The bootstrap data channel establishment process is triggered in advance during the call setup phase, before the actual voice/video transmission begins. The terminal device initiates the data channel negotiation as part of the call establishment sequence, ensuring that the data pathway is ready before service delivery starts, which improves reliability of end-to-end service implementation.
Solution Approach 2:
The service platform acts as an intermediary between terminal devices, coordinating the bootstrap data channel establishment. The service platform receives establishment requests from terminals, manages the negotiation process, and ensures proper routing and connectivity, thereby simplifying the complexity of direct peer-to-peer coordination while maintaining reliable end-to-end service.

AI summary
A communication method is provided. The method includes: monitoring, by a first terminal, a dialing event, triggering a process of establishing a bootstrap data channel with a service platform media module through the dialing event; after the bootstrap data channel with the service platform media module is successfully established, sending, by the first terminal, a service request message through the bootstrap data channel; and receiving, by the first terminal, a response message for the service request message returned by the service platform media module, and implementing at least one of an interface display or a service logic of a service based on an indication of the response message.
