Communication Method and Apparatus - A simplified explanation of the abstract
This abstract first appeared for US patent application 18167460 titled 'Communication Method and Apparatus
Simplified Explanation
The communication method described in this patent application involves establishing a protocol data unit session for a terminal device in a first network, which includes a specific quality of service flow. When the terminal device is handed over to a second network, the first quality of service flow is mapped to a first bearer in the second network.
- The method involves establishing a protocol data unit session for a terminal device in a first network.
- The session includes a specific quality of service flow.
- When the terminal device is handed over to a second network, the first quality of service flow is mapped to a first bearer in the second network.
- A second message is sent to an authentication, authorization, and accounting server, which includes an identifier of a first accounting session corresponding to the first quality of service flow and information about the first bearer.
- The second message instructs the authentication, authorization, and accounting server to update the first accounting session.
Potential Applications
- This communication method can be applied in various network environments where terminal devices need to be handed over from one network to another.
- It can be particularly useful in mobile communication networks where seamless handover between different networks is essential.
Problems Solved
- This method solves the problem of maintaining the quality of service flow for a terminal device when it is handed over from one network to another.
- It ensures that the first quality of service flow is mapped to a suitable bearer in the second network, allowing for uninterrupted communication.
Benefits
- The method allows for a smooth handover of terminal devices between different networks without compromising the quality of service.
- It ensures that the accounting session corresponding to the quality of service flow is updated correctly, providing accurate billing and accounting information.
Original Abstract Submitted
A communication method includes after a session management function network element establishes, for a terminal device, a protocol data unit session that is in a first network and that includes a first quality of service flow, and when a terminal device is handed over from the first network to a second network, if it is determined to map the first quality of service flow to a first bearer in the second network, the second message that includes an identifier of a first accounting session corresponding to the first quality of service flow and information about the first bearer may be sent to an authentication, authorization, and accounting server such that the second message indicates the authentication, authorization, and accounting server to update the first accounting session.
