Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication networks, user equipment data rates are limited by the access sub-network technology, and handovers between different networks can interrupt services, preventing simultaneous access to various services without disconnecting existing links.
Innovation Solution
A method that allows user equipment to establish links with multiple access sub-networks using different wireless communication technologies, enabling concurrent service access without handovers by forwarding service requests between sub-networks and optimizing data transmission through a core network, effectively combining data rates from various technologies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If user equipment establishes a link with a single access sub-network, then the network architecture is simple, but the data rate is limited to that access sub-network's capability
Solution Approach 1:
The patent combines multiple access sub-networks (GSM, UMTS, LTE, WiMax) into a unified access network architecture. The user equipment can simultaneously establish links with multiple access sub-networks, merging their data rates to achieve higher overall throughput while maintaining a simplified core network structure through a single serving gateway.
Solution Approach 2:
The serving gateway is designed with multi-functionality to handle user plane data transmission across multiple different access technologies. It can simultaneously manage data packets from GSM, UMTS, LTE, and WiMax networks, making it a universal node that adapts to various access types without requiring separate gateways for each technology.
2Adaptability or versatility
If user equipment hands over between access sub-networks to access different services, then service access flexibility is improved, but service interruption and handover delay occur
Solution Approach 1:
The user equipment proactively establishes links with multiple access sub-networks before needing to switch between services. This preliminary action ensures that when service requirements change, the equipment can immediately utilize the pre-established link without interruption or handover delay, maintaining service continuity while accessing different service types.
Solution Approach 2:
The patent enables continuous data transmission by maintaining simultaneous links with multiple access sub-networks. The serving gateway continuously routes data packets through the appropriate access network based on service requirements, ensuring uninterrupted service delivery without the need for breaking and re-establishing connections during service transitions.
3Adaptability or versatility
If user equipment disconnects existing link to access new service, then service switching capability is improved, but service interruption occurs
Solution Approach 1:
The user equipment merges multiple service connections by simultaneously maintaining links with different access sub-networks. Each link can carry different service types (voice, data, video), allowing the equipment to access multiple services concurrently without disconnecting any existing link, thus eliminating service interruption while maintaining service switching capability.

AI summary
The invention relates to a method of accessing, in a first access sub-network of a wireless communication network, the method including the steps of: establishing an initial link with a user equipment; receiving a second service request from the user equipment; forwarding the second service request to a core network; receiving second service downlink data from the core network or second service uplink data from a second access sub-network; and transmitting the second service downlink data to the second access sub-network or transmitting the second service uplink data to the core network, wherein, the first access sub-network and the second access sub-network adopt different wireless communication access technologies. With the solution of the invention, a limitation of the different wireless access technologies on a data rate of the user equipment can be eliminated so that the user equipment can access various types of services concurrently and the network architecture can be simplified.
