INFORMATION TRANSMISSION METHOD AND APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18477289 titled 'INFORMATION TRANSMISSION METHOD AND APPARATUS

Simplified Explanation

This patent application describes a method and apparatus for transmitting information in a mobile network. Here is a simplified explanation of the abstract:

  • The core network device obtains information about a second public land mobile network (PLMN) before a cell handover of a terminal device.
  • After the terminal device is handed over to a first cell, the core network device obtains information about the first PLMN of the first cell.
  • If the second PLMN is not in a PLMN list and the first PLMN is in the PLMN list, the core network device sends information to the first access network device corresponding to the first cell.
  • The information includes the PLMN list, which contains a set of PLMNs that allow the terminal device to perform minimization of drive test.

Potential applications of this technology:

  • Mobile network operators can use this method to improve the handover process between cells in their networks.
  • Terminal devices can benefit from a smoother transition between cells, resulting in better connectivity and user experience.

Problems solved by this technology:

  • The method addresses the issue of maintaining network connectivity during cell handovers.
  • It ensures that the terminal device can perform minimization of drive test, which helps optimize network performance.

Benefits of this technology:

  • Improved handover process leads to reduced call drops and improved call quality.
  • Minimization of drive test allows for efficient network optimization and resource allocation.
  • Enhanced user experience with seamless connectivity during cell handovers.


Original Abstract Submitted

This application provides an information transmission method and an apparatus. A core network device obtains second public land mobile network (PLMN) information of a second cell before a cell handover of a terminal device. After the terminal device is handed over to a first cell, the core network device obtains first PLMN information of the first cell. When a second PLMN does not belong to a PLMN list and a first PLMN belongs to the PLMN list, the core network device sends first information to a first access network device corresponding to the first cell, where the first information includes the PLMN list, and the PLMN list includes a PLMN set that allows the terminal device to perform minimization of drive test.
