A terminal switching method under high-speed mobility

Abstract

The invention discloses a terminal switching method under high-speed movement. During initialization, the conditions related to the switching of the terminal during multiple switchings, as well as the switching success rate under the corresponding conditions are recorded, and a switching information database is generated; when the When the terminal needs to switch between access points, according to the switching condition where the terminal is currently located and the generated switching information database, determine the switching success rate of the corresponding location; select the switching location and the corresponding switching location according to the determined switching success rate mode to switch between access points. The switching method can adapt to the high-speed mobile environment, greatly reduces the switching delay while ensuring the switching success rate, thereby enhancing the stability and continuity of communication.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a terminal switching method under high-speed movement. Background technique [0002] At present, according to the data released by the China Academy of Information and Communications Technology, two out of every three Chinese people use devices such as smartphones to access the mobile Internet. The current number of mobile Internet users in China has reached 875 million. In 2014, the number of mobile Internet users in China increased by 70 million compared with the previous year, and mobile Internet users accounted for more than 80% of the total Internet users. Mobile phones and mobile devices have become the first entrance to the Internet. According to a research paper published by the World Bank, the number of high-speed rail passengers increased from 128 million to 672 million between 2008 and 2013, and the number of passengers traveling by high-speed rail...

Problems solved by technology

However, in a high-speed mobile environment, such as the LTE network under the high-speed railway, the urban subway, or the high-speed movement of vehicles based on 802.11 Wifi access, the frequent switching caused by high-speed movement will cause the terminal access success rate to be low and drop. The high call rate seriously affects network performance; even between the same two base stations, simply relying on location information for handover will greatly reduce the success rate of handover, so there is an urgent need for a high-speed and reliable handover method to meet high-speed Handover requirements under mobile
