Abstract

The present invention provides a cell handover method and related equipment. The method includes a source base station determining a target frequency resource, the source base station sending a target frequency resource indication message to the target base station, and the source base station receiving the target frequency resource sent by the target base station. An indication message, where the indication message is used to indicate that the terminal to be handed over is allowed to switch to the target frequency resource. It can be seen that when the source base station determines the target frequency resource to be switched and accessed by the terminal to be handed over that resides in the source cell, the source base station can send a target frequency resource indication message to the target base station, and then When the switching terminal initiates access to the target cell, the terminal to be switched can directly switch to the target frequency resource, which improves the accuracy of the terminal accessing the target cell and effectively avoids the possibility of the terminal accessing the wrong frequency resource It improves the success rate of cell switching and reduces the delay of cell switching.

Description

technical field [0001] The embodiments of the present application relate to the field of communication technologies, and in particular, relate to a cell handover method and related equipment. Background technique [0002] Each frequency band is defined in the umts terrestrial radio access network (E-Utran) of the Universal Mobile Telecommunications System (UMTS) Terrestrial Radio Access Network (E-Utran) in the 3rd Generation Partnership Project (3GPP) agreement The corresponding relationship with the frequency, based on the corresponding relationship between the frequency band and the frequency, the 3GPP protocol proposes a multi-frequency band indicator (MFBI) cell. [0003] In the MFBI cell, two frequency bands can be supported at the same time, one is the main frequency band and the other is the secondary frequency band, and the working frequency of the MFBI cell is in the overlapping area of ​​the main frequency band and the secondary frequency band, and the terminal su...
