COMMUNICATION METHOD AND RELATED DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18146527 titled 'COMMUNICATION METHOD AND RELATED DEVICE

Simplified Explanation

The abstract describes a communication method and device that improve the success rate, coverage capability, and access capacity of a network device in a user equipment-to-network relay scenario.

The method involves a first terminal device receiving a radio resource control (RRC) message from a second terminal device.
The first terminal device then sends a message to a network device through a radio bearer using obtained configuration information.
The message includes an RRC message requesting the setup of an RRC connection between the second terminal device and the network device, along with identification information of the second terminal device.

Potential applications of this technology:

Improving communication reliability and coverage in scenarios where a user equipment device needs to relay messages to a network device.
Enhancing the access capacity of network devices in situations where multiple terminal devices need to establish connections simultaneously.

Problems solved by this technology:

Increasing the success rate of accessing network devices by terminal devices in a user equipment-to-network relay scenario.
Improving the coverage capability of network devices, ensuring reliable communication in areas with weak signal strength.
Enhancing the access capacity of network devices, enabling simultaneous connections from multiple terminal devices.

Benefits of this technology:

Higher success rate in establishing connections between terminal devices and network devices.
Improved coverage in areas with limited signal strength, ensuring reliable communication.
Increased access capacity, allowing multiple terminal devices to connect to the network device simultaneously.

Original Abstract Submitted

Embodiments of this application provide a communication method and a related device. In the method, a first terminal device receives a first radio resource control RRC message from a second terminal device, and then sends a first message to a network device through a first radio bearer configured by using obtained first configuration information. The first message includes a first RRC message that requests to set up an RRC connection between the second terminal device and the network device, and identification information of the second terminal device. In this way, communication between the second terminal device and the network device is implemented in a user equipment-to-network relay (U2N) scenario. This increases a success rate of accessing the network device by the second terminal device, enhances a coverage capability of the network device, and improves an access capacity of the network device.
