Network Access Gateway Selection for Service Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication network standards, particularly in UMTS and LTE, do not allow for flexibility in choosing the access gateway for user equipment, limiting the ability to adapt to different services and quality of service requirements, as session establishment is typically initiated by the user equipment and not the network.
Innovation Solution
A method and system that detect service requests within established sessions, determine the need for a new session, and dynamically select an appropriate access gateway based on service requirements, user equipment information, and network policies, allowing the network to initiate the establishment of new sessions with suitable gateways for optimized service delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If session establishment is initiated only by user equipment according to current standards, then the network structure remains simple and standardized, but the flexibility in choosing access gateway is limited and service adaptation capability is reduced
Solution Approach 1:
The patent inverts the traditional session establishment initiation right from user equipment to network side. The network device detects service requests in packets and autonomously initiates new session establishment towards appropriate access gateways, enabling flexible service adaptation while maintaining standardized procedures through controlled network-side initiation.
Solution Approach 2:
The network device acts as an intermediary between user equipment and access gateways. It detects service requirements from user equipment packets, determines appropriate access gateways based on service type and network policies, and initiates session establishment on behalf of user equipment, thereby providing flexible service adaptation without requiring complex user equipment modifications.
2Reliability
If a single access gateway is used for all services, then the network configuration is simplified, but the ability to provide differentiated quality of service is reduced
Solution Approach 1:
The patent applies local quality by selecting different access gateways based on specific service requirements. The network device determines appropriate access gateways according to service type, user equipment information, and network policies, allowing each service to be handled by the most suitable gateway with appropriate quality of service characteristics.
Solution Approach 2:
The patent changes the parameter of access gateway selection dynamically based on service requirements. The network device evaluates service type, user equipment information, and network policies to determine the most appropriate access gateway for each service, enabling differentiated quality of service through parameter-based gateway selection.
3Adaptability or versatility
If user equipment manages multiple data network identifiers and gateway selections, then service flexibility is improved, but user equipment complexity and operational burden increase
Solution Approach 1:
The patent extracts the complexity of multiple data network identifier management and access gateway selection from user equipment and centralizes it in the network device. The network device detects service requests, determines appropriate access gateways, and manages session establishment, thereby providing flexible service provisioning while keeping user equipment simple and easy to operate.
Solution Approach 2:
The network device provides self-service by autonomously detecting service requests from user equipment packets and independently initiating session establishment towards appropriate access gateways. This eliminates the need for user equipment to manage multiple data network identifiers or make gateway selection decisions, maintaining operational simplicity while achieving service flexibility.

AI summary
The invention relates to a method for communication, within a packet-mode communication network, between user equipment and a data network. A session is established between said user equipment and a data-network access gateway via an access network. The method includes: a step (E11) of detecting a request for access to a service on the basis of at least one packet transmitted by the user device via the established session; a first step (E12) of determining, on the basis of at least one criterion, that a new session is to be established; a second step (E21) of determining another access gateway, said other gateway being suitable for the service required by the user equipment; and a step (E22) of triggering the establishment of said new session between the user equipment and said other access gateway, said establishment being initiated by equipment of the packet-mode communication network.
