High-speed scene switching method based on multi-mode base stations

Abstract

The invention discloses a high-speed scene switching method based on multi-mode base stations, which mainly aims to solve the problem in the prior art that a user is easily disconnected during high-speed scene switching. The method adopts the technical scheme that each multi-mode station at least supports two types of radio access network (RAN) technologies, and through settings of corresponding power parameters, the coverage radius of each type of RAN is different, and network deployment of each type of the RAN meets full coverage requirements; between every two adjacent base stations, if a coverage radius RAN 1 of a first base station is larger than a coverage radius RAN 2 of the first base station, then the coverage radius RAN 1 of a second base station is smaller than the coverage radius RAN 2 of the second base station, so that successive interlacing is achieved; over-coverage is achieved between the different types of the RANs with the larger coverage radiuses of every two adjacent base stations; and the RANs with the smaller coverage radiuses are used for non-real-time multi-mode terminal data business, the RANs with the larger coverage radiuses are used for real-time multi-mode terminal data business, and the switching is achieved through inter-RAN. The method provided by the invention has the advantages that the user disconnection possibility is reduced, so that the high-speed motion scene switching performance for the mobile user is improved.

Description

technical field [0001] The invention belongs to the technical field of communication, and further relates to a high-speed scene switching method based on a multi-mode base station, which can be used to improve the switching performance of a mobile user in a high-speed motion scene. Background technique [0002] Handover is one of the key technologies in mobile communication technology. The quality of handover performance directly affects user satisfaction. How to effectively improve handover performance has become an important research topic in the field of mobile communication. [0003] When the mobile terminal is in a high-speed mobile state, due to the small overlapping coverage interval between two adjacent cells, the ideal handover area becomes smaller, resulting in the period from the user sending the measurement report to the serving base station sending the handover instruction The mobile terminal has already passed through the ideal handover area, so too early or to...
