Core Network Uplink Address Allocation for Dual-Connectivity Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dual-connectivity networks face challenges in efficiently allocating uplink addresses between a core network and an access network, particularly in scenarios involving multiple coupled base stations, leading to difficulties in managing communication sessions and ensuring adequate resource allocation.
Innovation Solution
The proposed solution involves configuring and allocating multiple uplink addresses among network element nodes within the access network, with the core network providing these addresses and the access network determining their usage and correspondence with downlink addresses, enabling effective session management and resource allocation across multiple nodes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple base stations are coupled to form a dual-connectivity network, then communication capacity is increased, but address allocation complexity between core network and access network increases
Solution Approach 1:
The patent segments the address allocation process into distinct phases: core network configures uplink addresses, access network receives and allocates them to specific base stations, then reports downlink addresses back to core network. This segmentation resolves the contradiction by dividing the complex multi-node address management into manageable sequential steps, maintaining high communication capacity while reducing allocation complexity.
2Productivity
If uplink addresses are allocated among multiple network element nodes, then session management efficiency is improved, but the complexity of determining address usage and correspondence increases
Solution Approach 1:
The patent implements a feedback mechanism where the access network allocates uplink addresses to network element nodes, uses them for session management, then reports the actual downlink addresses back to the core network. This feedback loop resolves the contradiction by enabling efficient session management through address allocation while managing complexity through structured reporting and correspondence tracking.
3Reliability
If at least two uplink addresses are configured and allocated among coupled base stations, then resource allocation adequacy is improved, but the difficulty of managing address correspondence increases
Solution Approach 1:
The patent applies preliminary action by having the core network configure and allocate uplink addresses to the access network before actual data transmission begins. The access network then pre-determines the correspondence between uplink and downlink addresses, ensuring adequate resource allocation is in place beforehand while simplifying subsequent address management during operation.

AI summary
Provided are an address allocation method and apparatus, a core network, a node, a network system and a medium. In at least one of the case of establishing a session, at least two uplink addresses are configured and send to an access network. The access network is a connectivity network formed by a coupling of at least two network element nodes. At least part of the at least two uplink addresses are used for being allocated among the network element nodes. The access network receives the at least two uplink addresses sent by the core network and allocates the at least two uplink addresses. The access network sends at least one downlink address to the core network and determines usage of the uplink addresses. The access network may determine a correspondence between the uplink address and the downlink address. The core network receives the downlink address.
