Network Element Multiplexing Voice Data Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communication systems require separate data connections for each payload data connection, leading to inefficient bandwidth usage when transmitting voice data, as the data fields of transmission protocols like IP, UDP, and RTP are larger than the compressed voice data, resulting in increased bandwidth requirements.
Innovation Solution
A network element that allocates payload data connections to multiplexed connections between network elements, using signaling messages to indicate readiness for multiplexing, allowing for reduced bandwidth usage without requiring new messages in existing protocols like IPBCP, by introducing new SDP attributes or MIME parameters to manage multiplexing and identification codes within multiplexed connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate data connections are established for each payload data connection, then reliability of individual connection is improved, but bandwidth efficiency deteriorates
Solution Approach 1:
The patent combines multiple separate payload data connections into a single multiplexed connection. Instead of establishing individual IP/UDP/RTP connections for each voice channel, the invention merges multiple voice channels into one shared connection, where multiple data streams are multiplexed over the same physical link. This reduces the number of protocol headers needed and improves bandwidth efficiency while maintaining connection reliability through proper stream identification and management.
Solution Approach 2:
The patent creates a universal multiplexed connection that can carry multiple different voice channels simultaneously. The single connection serves multiple functions by transporting various payload data connections (different voice channels) over the same infrastructure. This multi-functional approach allows the network to efficiently handle multiple calls or data streams using shared resources, thereby improving bandwidth utilization without sacrificing the reliability of individual channels.
2Adaptability or versatility
If protocol data fields are used for transmitting compressed voice data, then transmission protocol compatibility is improved, but bandwidth consumption increases
Solution Approach 1:
The patent merges multiple protocol data fields into a single shared transmission medium. Instead of each voice channel having its own complete set of IP/UDP/RTP headers, the invention combines multiple channels into one multiplexed stream where a single set of protocol headers serves multiple payload data connections. This significantly reduces the overhead bandwidth consumption while maintaining compatibility with standard transmission protocols through proper encapsulation and identification mechanisms.
3Loss of energy
If multiplexed connections are introduced, then bandwidth efficiency is improved, but device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the multiplexing function into distinct manageable components. The network element separates the complexity of multiplexing management from the actual data transmission, using identification codes to segment and track individual payload data connections within the multiplexed stream. This modular approach to handling multiple channels reduces the operational complexity compared to managing numerous separate connections, as the segmentation allows for systematic identification and management of each channel through coded identifiers.

AI summary
The invention relates to a network element for allocating at least one user data link to a multiplex connection between a first network element and a second network element. The first element generates a first signaling message and transmits it to the second network element, the first signaling message indicating that the first element is available to transfer at least one respective user data link via one respective multiplex connection. The second network element assigns one multiplex connection between the first and second network element to each of the user data link or selects a transfer outside a multiplex connection for the user data link in accordance with the indicated availability of the first network element and depending on whether the second network element supports the transfer of the at least one user data link via multiplex connection.
