Nomadic Base Station Emulating Core Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication networks, such as LTE networks, face challenges in extending coverage to areas outside the base station's coverage area without requiring significant hardware and software changes to the infrastructure.
Innovation Solution
The implementation of a nomadic base station and an application-level server that establishes a virtual core interface with the network core, allowing mobile devices outside the base station's coverage to communicate through a nomadic cell, using a back-to-back connection and shell messages to emulate a direct interface, thereby extending coverage without major infrastructure changes.

1Area of stationary object
If an additional base station or relay base station is added to extend coverage, then mobile devices outside the original coverage area can communicate with the network core, but hardware and software changes or additions to the infrastructure are required
Solution Approach 1:
A nomadic base station is introduced as an intermediary device that provides wireless communication coverage in areas outside the original base station's coverage area. The nomadic base station establishes a back-to-back connection with the original base station, creating a relay path for mobile devices to communicate with the network core without requiring direct connection to the network core infrastructure.
Solution Approach 2:
The nomadic base station emulates the functionality of a traditional base station by implementing the same protocol stack and communication interfaces. It copies the essential base station functions including radio resource management, connection handling, and message forwarding, allowing it to integrate seamlessly into the existing network architecture without requiring specialized new hardware or software modifications.
2Area of stationary object
If a relay base station with customized hardware is added, then coverage is extended to areas outside the original base station's coverage, but specialized hardware and software additions are required
Solution Approach 1:
The nomadic base station is designed as a universal device that can be deployed in various locations to extend coverage. It implements standard base station functionality that can serve multiple purposes: extending coverage area, providing temporary communication infrastructure, and acting as a mobile relay node. The device uses standard communication protocols and interfaces, making it compatible with existing network infrastructure without requiring location-specific customization.
Solution Approach 2:
The nomadic base station replicates the functionality of traditional base stations using standard off-the-shelf hardware components and software implementations. By copying the essential protocols and interfaces (such as the back-to-back connection interface and core network messaging protocols), it achieves base station functionality without requiring specialized customized hardware, thereby simplifying deployment and reducing costs.

AI summary
Systems and methods for extending coverage of a communication network. In one embodiment, a system includes a first base station configured to communicate with a first mobile communication device and to generate a core interface message. The system also includes a second mobile communication device and an application level server. The second mobile communication device is connected to the first base station and is configured to obtain the core interface message from the first base station, generate a message including the core interface message in an application layer of the message, address the message to the application level server, and transmit the message to the application level server. The application level server is configured to receive the message, extract the core interface message from the message, and transfer the core interface message to a network core to emulate an interface between the first base station and the network core.
