5G Multi-Access Resource Establishment via Indication Information
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Terminal devices in 5G mobile communications networks face challenges in supporting multi-access (MA) technology, which enables simultaneous use of both 3GPP and non-3GPP access technologies for data transmission, due to the need to establish and switch between network resources efficiently to meet varying quality of service (QoS) requirements.
Innovation Solution
A method and device configuration that allows a terminal device to request the establishment of network resources corresponding to both 3GPP and non-3GPP access technologies by sending indication information to session management function (SMF) or user plane function (UPF) network elements, enabling data transmission over multiple access technologies and supporting MA technology.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If network resources are established for both 3GPP and non-3GPP access technologies, then transmission reliability and adaptability are improved, but device complexity and resource management overhead increase
Solution Approach 1:
The patent segments the resource management process by introducing separate indication information mechanisms for controlling network resource establishment in 3GPP and non-3GPP access technologies. The SMF network element independently manages resources for each access type based on specific indication information, dividing the complex multi-access resource management into manageable segments that can be controlled separately while maintaining overall coordination.
Solution Approach 2:
The patent implements dynamic resource allocation by enabling the terminal device to send indication information that triggers dynamic establishment or release of network resources based on real-time transmission needs. The resource configuration changes dynamically in response to transmission requirements, allowing the system to adapt between different access technologies without manual reconfiguration, thus improving reliability while managing complexity through automated dynamic adjustment.
2Adaptability or versatility
If network resources are dynamically established and switched between access technologies, then adaptability and transmission efficiency are improved, but loss of time for resource establishment increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring indication information mechanisms that allow rapid resource establishment when needed. The terminal device and network elements are pre-equipped with the capability to send and process indication information, so when transmission requirements change, resources can be established or switched without delay. This preliminary preparation of the control mechanism reduces the time penalty associated with dynamic resource establishment.
Solution Approach 2:
The patent implements feedback loops where terminal devices monitor transmission requirements and send indication information to network elements, which then establish or release resources accordingly. This closed-loop feedback system enables rapid adaptation to changing transmission needs by continuously monitoring and responding to requirements, reducing the time loss for resource establishment through automated real-time adjustments.
3Reliability
If indication information is sent to establish network resources, then transmission reliability is improved, but use of energy and signaling overhead increase
Solution Approach 1:
The patent applies partial action by implementing indication information mechanisms that are activated only when resource establishment or switching is actually needed. Rather than continuously managing all possible access technologies, the system sends indication information selectively based on real-time transmission requirements, establishing resources only for the access technologies that are currently needed. This partial activation approach maintains reliability while reducing energy consumption compared to continuous full-resource management.

AI summary
A method for establishing a resource, includes: establishing a network resource corresponding to a first access technology of a quality of service (QOS) flow; and receiving first indication information sent by a terminal device or a user plane function (UPF) network element, where the first indication information is used to instruct to establish a network resource corresponding to a second access technology of the QoS flow, the first access technology is one of a 3GPP access technology or a non-3GPP access technology, and the second access technology is the other of the 3GPP access technology or the non-3GPP access technology.
