Problems solved by technology
If it is necessary to perform handover between a macro cell under the coverage of a macro base station and a home base station cell under the coverage of a femtocell, the existing technology requires the user equipment to read a large amount of broadcast information of the femtocell, thus wasting air interface resources and increasing large switching delay

The embodiment of the invention relates to a cell switching method and a cell switching system and access devices. The cell switching method comprises the following steps: acquiring home base station information associated with the first access device; and sending first access device information and the home base station information to the second access device for the second access device to determine target cells in a home base station coverage range for user equipment according to the first access device information and the home base station information. The other cell switching method comprises the following steps: receiving first access device information from the first access device and home base station information associated with the first access device; and determining target cells in a home base station coverage range for user equipment according to the first access device information and the home base station information. The embodiment of the invention is favorable for saving idle resources and reducing time delay for switching the cells.
Description
technical field [0001] The embodiments of the present invention relate to communication technologies, and in particular to a method and system for cell handover and access equipment. Background technique [0002] A home base station (Home evolved NodeB, referred to as HeNB; or Home NodeB, referred to as HNB) is generally a small base station device purchased and installed by users, and is usually connected to the operator's core network via an IP network. Users can turn on or off the home base station at any time according to actual needs. It can be seen that femtocells have the characteristics of dynamic deployment, large number, and strong access randomness. [0003] Different from home base stations, macro base stations (Macro eNB) are base station equipment deployed by operators after network planning. There can be standard communication interfaces (such as X2 interface) between macro base stations with adjacent cells, and the adjacent cell information between differen...
