Description
一种确定切换小区的方法以及基站 技术领域
发明涉及通信领域, 尤其涉及一种确定切换小区的方法及基站。 背景技术
长期演进( Long Term Evolved, LTE )网络是目前第三代合作伙伴计划( 3rd Generation Partnership Program, 3 GPP )组织中各厂商积极研究的一种移动通信 网络, 也是通用移动通信系统 ( Universal Mobile Telecommunication System, UMTS )的演进网络。 LTE网络的目的是提供一种能够降低时延、 提高用户数据 速率、 增加系统容量及降低覆盖成本的网络。 LTE 网络的空中接口一般通过部 署演进节点 B ( evolved Node B, eNB )来实现, 用户设备通过与 eNB通信可以 实现移动业务的空口传输。
目前, 在长期演进( Long Term Evolution, LTE )技术中, 为了用户设备服 务的连续性, 当处于连接状态的用户设备移动到小区边缘时, 基站将该用户设 备平滑切换到相邻小区。 现有的切换方法如下:
基站为用户设备配置测量目标与测量上报方式; 其中, 测量目标为同频、 异频或异系统频点, 同频是指与用户设备的服务小区中心频点相同的频带, 异 频是指与用户设备的服务小区中心频点不同, 但属于同一系统制式的频带, 异 系统频点是指与用户设备的服务小区不同制式系统的频点。 其中, 测量上报方 式可以是周期性上报或测量事件触发上报。 用户设备对测量目标进行测量, 当 满足测量上报要求时, 向基站上报测量结果; 基站根据用户设备上报的测量结 果, 为用户设备选择合适的切换目标小区, 并将用户设备切换至目标小区。
由于用户设备需要开启其他非数据传输射频 (Radio Frequency, RF )进行 异频或异系统频点测量, 这样额外开启的 RF将增加用户设备的功耗; 同时, 使 用测量间隙进行异频或异系统频点测量, 将减少用户设备数据接收时间, 降低 数据传输效率。 发明内容

上述技术方案中, 接收用户设备发送的位置信息, 获取所述用户设备所在 服务基站的相邻小区的覆盖范围, 根据所述用户设备的位置信息和所述相邻小 区的覆盖范围确定所述用户设备的切换目标小区, 这样在用户设备在确定切换 目标小区过程中, 用户设备不需要启动非正在监听服务小区的接收设备进行异 频和 /或异系统测量从而可以减少用户设备的功耗。 或者, 用户设备不必使用测 量间隙进行异频或异系统频点测量, 增加了用户设备接收数据的时间, 以提高 用户设备的数据传输效率。
