System Signature Distribution for Multi-Operator Network Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Inefficient energy consumption due to frequent and repetitive transmissions of system information in wireless communication networks, especially in multi-operator scenarios where third-party networks are integrated, leading to increased interference and energy expenditure.
Innovation Solution
Implementing a system where network nodes transmit a system signature that terminal devices can use to retrieve access information from a stored access information table, reducing the need for frequent broadcasts of system information and allowing seamless integration of third-party networks into larger operator networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If system information is broadcast periodically every 10 ms, then terminal devices can access the network properly, but energy consumption becomes significant
Solution Approach 1:
The patent extracts the essential access information from the periodic system information broadcasts and stores it in a terminal device memory. Instead of requiring terminal devices to continuously receive and process full system information blocks every 10 ms, the critical access parameters are extracted and cached locally, allowing terminal devices to operate independently of frequent broadcasts while maintaining network access capability.
Solution Approach 2:
The patent implements preliminary action by pre-configuring terminal devices with system information during initial network attachment or through update mechanisms. The terminal device receives and stores access information in advance, so it doesn't need to continuously monitor periodic broadcasts. This preliminary provisioning reduces the frequency of information exchange and lowers energy consumption while maintaining reliable network access.
2Adaptability or versatility
If third party networks broadcast their own PLMN IDs and synchronization signals, then network integration is achieved, but interference increases and energy consumption rises
Solution Approach 1:
The patent merges the third party network into the host operator's network infrastructure by having the host network node distribute access information for the third party network. Instead of the third party network broadcasting independently with its own PLMN IDs and synchronization signals, both networks are integrated under a unified broadcast structure managed by the host network, reducing interference while maintaining integration capability.
Solution Approach 2:
The host network node acts as an intermediary that distributes access information for both the host operator and third party networks. Rather than allowing direct competition between multiple independent broadcasts, the intermediary host network consolidates the information distribution function, enabling terminal devices to access both networks through a single integrated interface, thereby reducing overall interference and energy consumption.

AI summary
Methods and apparatus are disclosed for distributing access information in a multi-operator scenario. In a multi-operator network (100), network nodes (130, 140, 150) are configured to transmit one or more system signatures and one or more access information tables. A terminal device (200) can use a received system signature to retrieve a set of system information from an access information table. The retrieved system information is used by the terminal device (200) to initiate a random access procedure to gain access to an operator network.
