Abstract: The present disclosure discloses a method, apparatus and system for implementing an X2 handover. In the scheme of the present disclosure, a Base Station (BS) initiates, after having determined the need for a handover and detected that there exists an X2 connection between the BS and a target BS and that the BS and the target BS are within the management scope of a same MME, an X2 handover, if it is determined that there exists a connection between the target BS and the serving gateway connected with the BS according to acquired serving gateways connected with an other BS. Here, the term “an/the other BS” refers to one different from the BS determines the need for a handover, and includes the target BS designated for a handover. By using the scheme provided herein in which a determination on whether an X2 handover condition is currently met, that is, whether there exists a connection between the target BS and the serving gateway connected with the BS, is accurately made before the BS initiates a handover, and an X2 handover is initiated by the BS when the X2 handover condition is met, the present disclosure effectively avoids the possibility of the failure of an X2 handover, increases the success rate of an X2 handover, and provides excellent user experience.

Abstract translation: 本公开公开了一种用于实现X2切换的方法，装置和系统。 在本公开的方案中，基站（BS）在确定了对切换的需要并且检测到在BS与目标BS之间存在X2连接以及BS和目标BS在 如果根据与其他BS连接的获取的服务网关确定目标BS和与BS连接的服务网关之间存在连接，则相同MME的管理范围，X2切换。 这里，术语“一/其他BS”是指与BS不同的一个BS确定切换的需要，并且包括被指定用于切换的目标BS。 通过使用本文提供的方案，其中确定当前是否满足X2切换条件，即在BS发起切换之前是否存在目标BS与与BS连接的服务网关之间的连接 ，并且当满足X2切换条件时，由BS发起X2切换，本公开有效地避免了X2切换失败的可能性，提高了X2切换的成功率，并且提供了优异的用户体验。
