Media Gateway Bypass via Preceding Device Connectivity Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In packet-based telecommunications networks, media gateways often relay media data through all devices in the communication session path, leading to wastage of network resources and degradation of media quality due to increased latency, as they lack the ability to determine whether they are necessary for the media path.
Innovation Solution
The method involves including preceding device connectivity data in outbound communication session setup request messages to enable media bypass, allowing ensuing devices to determine if a media gateway can be bypassed based on connectivity settings, thereby optimizing the media path and reducing unnecessary relay.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If media gateway relays media data through all devices in the communication session path, then network security and control are maintained, but network resources are wasted and media quality degrades due to increased latency
Solution Approach 1:
The patent applies preliminary action by including connectivity data in outbound communication session setup request messages before media data transmission begins. This allows ensuing devices to pre-determine whether a media gateway can be bypassed, enabling optimal media path selection before resources are consumed, thus resolving the contradiction between maintaining security control and reducing resource waste
Solution Approach 2:
The patent implements dynamics by making the media gateway bypass decision configurable and adaptable based on connectivity data. The system dynamically determines whether to relay or bypass media data through the media gateway based on real-time connectivity information, allowing the network to adapt between security-focused relay mode and efficiency-focused bypass mode
2Reliability
If media gateway relays media data through all devices in the communication session path, then network security and control are maintained, but media quality degrades due to increased latency
Solution Approach 1:
The patent applies preliminary action by including connectivity data in outbound communication session setup request messages before media data transmission begins. This allows ensuing devices to pre-determine whether a media gateway can be bypassed, enabling optimal media path selection before resources are consumed, thus resolving the contradiction between maintaining security control and reducing resource waste
Solution Approach 2:
The patent applies skipping by enabling the media gateway to be bypassed in the media path when connectivity data indicates that direct connection is possible. This allows media data to skip unnecessary relay through the media gateway, reducing latency while maintaining security control through the signaling path
3Reliability
If media gateway relays media data, then safe option is selected for security, but valuable network resources are wasted
Solution Approach 1:
The patent applies preliminary action by including connectivity data in outbound communication session setup request messages before media data transmission begins. This allows ensuing devices to pre-determine whether a media gateway can be bypassed, enabling optimal media path selection before resources are consumed, thus resolving the contradiction between maintaining security control and reducing resource waste
Solution Approach 2:
The patent applies feedback by using connectivity data from preceding devices to inform subsequent devices about media path options. This feedback mechanism enables ensuing devices to make informed decisions about whether to bypass the media gateway, optimizing resource efficiency while maintaining security through the signaling path

AI summary
There is provided a method of enabling media bypass for a media gateway in a telecommunications network which includes a plurality of media gateways via which a signaling path for transfer of signaling information for setup of a communication session between endpoint devices can be established and via which a media path for transfer of media data between the endpoint devices during the communication session can be established. The method includes receiving, at the media gateway, an inbound communication session setup request message requesting setup of a communication session between an originating endpoint device and a terminating endpoint device in the telecommunications network, the inbound communication session setup request message being transmitted along an inbound signaling path to the media gateway; transmitting, from the media gateway, an outbound communication session setup request message in response to receiving the inbound communication session setup message, the outbound communication session setup request message being transmitted along an outbound signaling path from the media gateway; and including preceding device connectivity data in the outbound communication session setup request message, the preceding device connectivity data indicating at least one media connectivity setting for at least one preceding device which is located before the media gateway in the inbound signaling path, the at least one connectivity setting identifying one or more other devices to which the at least one preceding device is configured to be connectable in the media path, to enable bypass of the media gateway in the media path if an ensuing device in the outbound signaling path determines that such bypass should be conducted.
