Embodiment Construction

[0024] There is also a kind of home base station (Home eNB, HeNB) in the LTE system. As the exclusive resources of private users, femtocells are deployed in private places such as families, groups, companies or schools. They can provide users with various high-speed wireless access services and provide preferential tariffs, and at the same time make up for the existing distributed cellular wireless networks. Insufficient coverage of the communication system. A cell covered by a home base station is called a home base station cell. At present, there are three access modes of the home base station: open mode, closed mode and hybrid mode. Among them, the open mode home base station allows all users to access, and the corresponding cell is called an open mode home base station cell (open cell). There is no difference between this type of cell and ordinary cells; the closed mode home base station only allows authorized mobile terminals to access, such as authorized family members,...

Abstract

The invention provides a base station and a method for switching to a CSG cell. The method includes that when an indication for reading the system information of an adjacent CSG cell is sent to a mobile terminal in the dual connection, the information about the mobile terminal reading the system information of the adjacent CSG cell or creating the autonomous gap is sent to a secondary base station connected with the mobile terminal, when the information about determining the mobile terminal itself as the member of the adjacent CSG cell from the mobile terminal and the global cell identity of the adjacent CSG cell are received, the switching decision is made, the switching command is sent to the mobile terminal, so that the mobile terminal can be switched to the adjacent CSG cell. According to the invention, the waste of scheduling resources can be prevented during the CSG cell switching can be prevented and the dual connection of the mobile terminal is maintained.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a master base station and a method for handover to a CSG cell. Background technique [0002] Dual Connectivity (Dual Connectivity) is a technology in which a mobile terminal (or called a user terminal UE) in a connected state uses the wireless resources of two base stations at the same time. The two base stations are connected by a non-ideal backhaul link, and one of them The base station is the main base station (Master eNB, MeNB), and the other is the secondary base station (SeNB). The main base station is responsible for the radio link control of the mobile terminal, that is, RRC (Radio Resource Control). The RRC signaling of the mobile terminal passes through the main base station and the For air interface transmission between mobile terminals, the mobile terminal receives system messages and paging messages sent by the primary base station. There is data inter...
