Session Management for IPTV and Web Service Convergence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication networks, simultaneous access to multiple services by users leads to 'blind' TCP connections competing for quality of service and bandwidth, resulting in inefficient network resource management and potential service degradation.
Innovation Solution
A method where a first network equipment intercepts messages for accessing additional services and redirects user equipment to establish a single communication session, combining data from multiple services within this session, allowing for centralized management and optimization of bandwidth and QoS.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple TCP connections are established for simultaneous service access, then service convergence is enabled, but network resource efficiency deteriorates due to blind competition between sessions
Solution Approach 1:
The patent merges multiple TCP connections into a single unified connection managed by a specific network device. This allows the user equipment to access multiple services through one connection rather than establishing separate blind TCP connections for each service, thereby eliminating session competition while maintaining service convergence capability
Solution Approach 2:
The patent introduces an intermediary network device that acts as a mediator between user equipment and multiple service providers. This intermediary intercepts service access requests, establishes a unified TCP connection, and manages data transmission for multiple services through this single connection, resolving the efficiency problem caused by multiple independent sessions
2Adaptability or versatility
If separate TCP sessions are used for each service, then service independence is maintained, but QoS negotiation efficiency deteriorates due to lack of global session overview
Solution Approach 1:
The patent makes a single TCP connection universal by enabling it to carry multiple service data streams simultaneously. The network device manages this unified connection to handle different services with independent QoS requirements, eliminating the need for separate QoS negotiations for each service while maintaining service independence through logical separation within the unified connection

AI summary
The present invention relates to the management of communication sessions during access to services by a user equipment (10). In an application of the invention: a first communication session (31, S1) is established between a contents server (30, CS1) and the user equipment so as to transmit IPTV data; the terminal sends a DNS, DHCP or ARP type services discovery and attachment request relating to a website (40) to be accessed; the request is intercepted and processed in such a way as to transmit, to the user equipment, a network address of the contents server, which address is associated with the website; the user equipment sends, on said network address of the contents server, an HTTP request for access to a part of the website by combining a URL address relating to the website with said network address of the contents server; on receipt of said HTTP access request, the contents server identifies a web server (40) associated with the website by virtue of the reception network address, and despatches, to the web server, a request for access to the relating URL address to obtain data from the web service, the content server assembles the web data received from the web server with the IPTV data, so as to transmit the set of data to the user equipment via said communication session.
