HANDOVER METHOD AND DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18216827 titled 'HANDOVER METHOD AND DEVICE
Simplified Explanation
The patent application describes a method for reducing service interruption during handover between network devices. Here are the key points:
- The method involves sending a configuration message from a first network device to a terminal device.
- The configuration message instructs the terminal device to configure a ciphering/deciphering function associated with a second network device.
- The terminal device is also instructed to share a data packet numbering/reordering function.
- The terminal device is already configured with a ciphering/deciphering function associated with the first network device.
- The first network device receives a configuration complete message from the terminal device.
- This allows the terminal device to simultaneously perform data transmission with both the first and second network devices during handover.
Potential applications of this technology:
- Mobile networks: This method can be applied in mobile networks to ensure seamless handover between different base stations or access points.
- Wireless communication: It can be used in wireless communication systems to minimize service interruptions when switching between different network devices.
- Internet of Things (IoT): This method can be beneficial in IoT networks where devices need to maintain connectivity while moving between different network nodes.
Problems solved by this technology:
- Service interruption during handover: The method reduces or eliminates service interruptions that occur when a terminal device switches between network devices.
- Data transmission efficiency: Simultaneous data transmission with multiple network devices allows for a more efficient use of network resources and ensures uninterrupted communication.
Benefits of this technology:
- Seamless handover: The method ensures a smooth transition between network devices, minimizing service disruptions for users.
- Improved user experience: By reducing service interruptions, users can enjoy uninterrupted communication and data transmission.
- Efficient network utilization: Simultaneous data transmission with multiple network devices optimizes network resources, leading to improved overall network performance.
Original Abstract Submitted
A method includes: sending, by a first network device, a first configuration message to a terminal device, where the first configuration message is used to instruct the terminal device to configure a second ciphering/deciphering function associated with a second network device and share a first data packet numbering/reordering function, and the terminal device is configured with the first data packet numbering/reordering function and a first ciphering/deciphering function associated with the first network device; and receiving, by the first network device, a first configuration complete message sent by the terminal device. In this embodiment, the first configuration message is used so that the terminal device may configure the function associated with the second network device. Therefore, during handover, the terminal device may simultaneously perform data transmission with the second network device and the first network device, to reduce or avoid a service interruption time caused by handover.
