Wireless Integrated Access Device VoIP Gateway
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
VoIP systems often experience quality issues due to congestion, bandwidth constraints, and packet loss, and some endpoint devices are not compatible with Voice over ATM and Voice over DSL technologies, leading to compatibility and reliability problems.
Innovation Solution
A wireless integrated access device (WIAD) is deployed on the customer's premise, compatible with Voice over ATM and Voice over DSL on the network side, while supporting VoIP on the customer premise side, using a VoIP server to establish wireless connections with IP-enabled endpoint devices, leveraging the reliability of dedicated-connection switching technologies like ATM and DSL.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If VoIP is used for voice communication, then compatibility with IP-enabled endpoint devices is improved, but communication quality and reliability deteriorate due to congestion, bandwidth constraints, and packet loss
Solution Approach 1:
The patent introduces a gateway device as an intermediary between the dedicated-connection network (ATM/DSL) and the packet-switched VoIP network. This gateway translates and bridges the two different communication protocols, allowing IP-enabled devices to communicate reliably by mediating the connection through a device that handles protocol conversion and quality assurance.
2Reliability
If dedicated-connection switching technology (Voice over ATM or Voice over DSL) is used, then communication quality and reliability are improved, but compatibility with VoIP endpoint devices deteriorates
Solution Approach 1:
The gateway serves as an intermediary that accepts connections from dedicated-connection networks (Voice over ATM or Voice over DSL) on one side and VoIP connections on the other side. It performs protocol translation and signaling conversion, enabling compatibility between endpoint devices that require VoIP and network infrastructure that uses dedicated-connection switching technology.
Solution Approach 2:
The gateway dynamically changes communication parameters including protocol type, signaling methods, and transmission formats based on the requirements of the connected endpoint devices and the available network infrastructure. This allows the system to adapt between different voice transmission technologies while maintaining consistent service quality.
3Reliability
If a gateway is introduced to bridge dedicated-connection networks and VoIP networks, then compatibility and reliability are improved, but device complexity increases
Solution Approach 1:
The patent combines multiple functions including protocol translation, signaling conversion, call control, and quality management into a single integrated gateway device. This merging of functions reduces overall system complexity by consolidating what would otherwise require multiple separate components while maintaining improved reliability and compatibility.

AI summary
A method and apparatus for handling a call using a wireless integrated access device that is compatible with Voice over ATM and Voice over DSL on a network side while being compatible with VoIP on a customer premise side are disclosed. For example, the present method employs a wireless integrated access device for receiving an incoming call from a broadband access network that uses dedicated connection switching. In turn, the method establishes a wireless connection for the incoming call with at least one VoIP enabled endpoint device located at a customer premise.
