COMMUNICATION METHOD AND APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 17958242 titled 'COMMUNICATION METHOD AND APPARATUS
Simplified Explanation
The patent application discloses a communication method and apparatus that allows a terminal to access a specific network slice in a tracking area. Here are the key points:
- The first AMF device receives a request message from a terminal, which includes the identifier of the network slice the terminal wants to access and the identifier of the tracking area it is located in.
- If the first AMF device determines that the tracking area supports the requested network slice, it sends a response message to the terminal.
- The response message includes a radio access selection priority index for the requested network slice, which helps the terminal select an access network device that supports the network slice.
- Even if the terminal is currently connected to an access network device that does not support the requested network slice, it can re-access an access network device that does support it.
Potential applications of this technology:
- This communication method can be used in various wireless networks, such as 4G and 5G, to enable terminals to access specific network slices based on their needs.
- It can be particularly useful in scenarios where different network slices offer different services or quality of service, allowing terminals to connect to the most suitable network slice.
Problems solved by this technology:
- The method solves the problem of terminals not being able to access specific network slices in a tracking area, even if they are available, by providing a mechanism for selecting the appropriate access network device.
- It also solves the problem of terminals being limited to the network slice supported by their current access network device, allowing them to re-access a different device that supports the desired network slice.
Benefits of this technology:
- The method improves the flexibility and efficiency of network slice access for terminals, as they can easily connect to the network slice that best meets their requirements.
- It enhances the overall user experience by enabling terminals to access specialized services or higher-quality network slices.
- The method optimizes network resource utilization by allowing terminals to connect to the most suitable network slice, reducing unnecessary traffic on incompatible network slices.
Original Abstract Submitted
This application discloses a communication method and apparatus. A first AMF device receives a first request message, where the first request message includes an identifier of a first network slice that a terminal requests to access and an identifier of a tracking area in which the terminal is located. When the first AMF device determines that the tracking area supports the first network slice, the first AMF device sends a response message, where the response message includes a first radio access selection priority index corresponding to the first network slice. The first radio access selection priority index is for selection of an access network device that supports the first network slice at the terminal. Even if an access network device currently accessed by the terminal does not support the first network slice, the terminal may re-access the access network device that supports the first network slice.
