Home Base Station Local Remote Traffic Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Home base stations in telecommunications systems cannot distinguish between local and remote traffic, leading to inefficient traffic handling and increased latency and costs for users, as all traffic is treated equally regardless of its origin or destination within the local network.
Innovation Solution
The home base station examines the destination address of uplink data packets to determine whether to route them locally within the home network or through the core network, allowing for separate handling of local and remote communication sessions, thereby reducing latency and offloading the core network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all traffic is routed through the core network, then centralized control and security are maintained, but latency increases and core network resources are consumed for local communications
Solution Approach 1:
The patent segments traffic into local and remote flows by examining destination addresses in uplink data packets. Local traffic (destined for devices on the home LAN) is separated from remote traffic and routed through different paths, allowing local communications to bypass the core network while maintaining centralized control for remote communications.
Solution Approach 2:
The home base station acts as an intermediary that inspects destination addresses and determines routing paths. It serves as a local decision point that can forward packets either to the core network or directly to local nodes, thereby reducing latency for local traffic while maintaining core network involvement for remote traffic.
2Device complexity
If all traffic is routed through the core network, then network management is simplified, but core network resources are unnecessarily consumed and costs increase
Solution Approach 1:
The patent segments traffic based on destination address analysis, separating local traffic that can be handled within the home network from remote traffic requiring core network resources. This segmentation prevents unnecessary consumption of core network resources for local communications while maintaining simplified management through automated address-based routing decisions.
Solution Approach 2:
The home base station performs self-service by autonomously examining destination addresses and making routing decisions without requiring complex centralized management for each packet. This enables the local network to handle its own traffic independently, reducing core network resource consumption while maintaining manageable complexity through automated local intelligence.
3Loss of time
If local transportation is enabled, then latency for local communications is reduced, but the home base station must examine and make routing decisions for each packet
Solution Approach 1:
The patent applies preliminary action by examining the destination address field of uplink data packets at the home base station before routing decisions are made. This early inspection allows the system to identify local traffic and route it appropriately, reducing latency while keeping the processing logic relatively simple through address field analysis rather than deep packet inspection.

AI summary
The present invention relates to methods and devices that allow for different types of transportation of data packets (6) in conjunction with a home base station (1). Traffic arriving in the home base station (1) from a mobile terminal (2) connected to the home base station (1) can be transported either via a core network (15) of a mobile telecommunications system or by means of local transportation, which implies that the traffic is forwarded to a local node (4) in a local network (20) without passing the core network (15). The home base station (1) examines data packets (6) that are received from the mobile terminal (1) and determines the appropriate type of transportation for each data packet (6). Thus it is not required for traffic that is destined for local nodes (4) to pass the core network (15), which allows for efficient traffic forwarding with several benefits such as offloading the core network (15).
