Embodiment Construction

[0030] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0031] Figure 4 It is a flowchart of a cell handover method according to an embodiment of the present invention. Such as Figure 4 As shown, the cell handover method mainly includes the following processing:

[0032] Step S402: the source base station uses the historical information of the UE to assist in determining the handover mode and / or the target cell;

[0033] Step S404: The source base station initiates a handover procedure according to the determined handover mode and / or the target cell.

[0034] In related technologies, the time delay and overhead of UE switching to a closed or hybrid cell are relatively large. in such as Figure 4 In the cell handover method shown, the cell informat...

Abstract

The present invention provides a cell switching method and a base station. The cell switching method includes: a source base station determines a switching mode and / or a target cell by using historical information of a UE; and a source base station initiates a switching process according to the determined switching mode and / or target cell. According to the technical solution provided by the present invention, the time delay and overhead for UE switching to a closed or hybrid cell can be effectively reduced.

Description

technical field [0001] The present invention relates to the communication field, in particular to a cell switching method and a base station. Background technique [0002] The system architecture of the LTE standard formulated by 3GPP is called the Evolved Packet System (EPS for short), and the EPS consists of the Evolved Universal Terrestrial Radio Access Network (E-UTRAN for short) and the Evolved Packet Core network (Evolved Packet Core, referred to as EPC), wherein, the architecture of E-UTRAN can refer to figure 1 . [0003] In the E-UTRAN architecture, a base station (NodeB, abbreviated as eNB) is a network device that provides wireless access for user equipment (User Equipment, abbreviated as UE). The base stations are connected through the X2 interface, and the base station and the mobility management entity (Mobility Management Entity, abbreviated as MME) or Serving Gateway (Serving Gateway, abbreviated as S-GW), connected through S1 interface, where the interface...
