Description

一种控制用户设备切换的方法、 基站、 用户设备及系统 技术领域
本发明涉及通信技术领域，具体涉及一种控制用户设备切换的方法、基站、 用户设备及系统。
背景技术
随着蜂窝技术的不断发展， 宏基站和微基站共同组网的方式越来越普及， 这样可以增加系统容量， 为用户提供更高的服务速率， 更大的服务带宽。 宏基 站的覆盖范围可以称为宏小区， 微基站的覆盖范围可以称为小小区。
但由于小小区的覆盖范围小， 用户设备 ( User Equipment, UE )移动时切 换频繁，会影响系统性能以及用户感受。 因此在宏小区和小小区共同覆盖的范 围里， 可以使宏小区和小小区共同为用户设备提供服务，也就是使用户设备与 微基站和宏基站保持双连接，从而让部分用户数据在小小区传输的情况下，保 持用户设备和宏基站的连接， 从而避免频繁切换。
在对现有技术的研究和实践过程中，本发明的发明人发现当有多个基站可 以为用户设备提供双连接服务时 ,基站之间并不知道其他哪个基站还可以为用 户设备提供双连接服务，从而导致控制用户切换时， 无法准确切换到能够提供 双连接服务的基站。

下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清 楚、 完整地描述， 显然， 所描述的实施例仅仅是本发明一部分实施例， 而不是 全部的实施例。基于本发明中的实施例， 本领域技术人员在没有作出创造性劳 动前提下所获得的所有其他实施例， 都属于本发明保护的范围。
本发明实施例中的多连接指用户设备可以同时与多个基站或者多个基站 中的小区保持连接， 可以为双连接、 三连接、 四连接等等， 对具体连接的基站 或者小区的数量不做限制。
参阅图 1 ,本发明实施例提供的控制用户设备切换的方法的一实施例包括：
101、 获取用于控制用户设备切换的指示信息， 所述指示信息用于指示能 为所述用户设备提供多连接服务的小区或者基站。
本发明实施例中以双连接为例， 当正在为用户设备 UE提供服务的基站为 eNB 1和 eNB2时， eNB 1获取到 eNB2和 eNB3可以为 UE提供双连接服务的指示信 息， 其中， eNBl获取到的指示信息用于指示能为 UE提供双连接服务的基站为 eNBl和 eNB2, 或者， eNB2和 eNB3。
当正在为用户设备 UE提供服务的基站为 eNBl的小区 1和 eNB2的小区 2时， eNB 1获取到 eNB2的小区 2和 eNB3的小区 3可以为 UE提供双连接服务的指示信 息， 其中， eNBl获取到的指示信息用于指示能为 UE提供双连接服务的小区为 eNBl的小区 1和 eNB2的小区 2, 或者， eNB2的小区 2和 eNB3的小区 3。
102、 根据所述指示信息， 从所述能为所述用户设备提供多连接服务的小 区或者基站中确定待切换的目标小区或者目标基站。
如上个步骤中的例子， eNBl可以根据指示信息， 确定待切换的目标小区 为 eNB3小区 3 , 或者， 确定待切换的目标基站为 eNB3。
103、 向所述目标小区所在的基站或者所述目标基站发送切换请求， 以使 所述目标小区所在的基站或者所述目标基站为所述用户设备提供连接服务。
eNB 1确定待切换的目标小区为 eNB3小区 3 , 或者， eNB 1确定待切换的目 标基站为 eNB3后， eNBl就可以向 eNB3发送切换请求， 让 eNB3与 eNB2—同为 UE提供双连接服务。
本发明实施例釆用获取用于控制用户设备切换的指示信息，所述指示信息 用于指示能为所述用户设备提供多连接服务的小区或者基站；根据所述指示信 息，从所述能为所述用户设备提供多连接服务的小区或者基站中确定待切换的 目标小区或者目标基站；向所述目标小区所在的基站或者所述目标基站发送切 换请求，以使所述目标小区所在的基站或者所述目标基站为所述用户设备提供 连接服务。与现有技术中服务基站不知道其他哪些邻基站可以为用户设备提供 双连接服务相比，本发明实施例提供的控制用户设备切换的方法， 可以准确将 用户设备切换到可以为用户设备提供多连接服务的基站。

本发明实施例中，所述双连接指示信息可以用小区间双连接指示标识来表 示或者基站间双连接指示标识来表示。例如： 当指示信息为小区间双连接指示 标识时， 该指示信息用于指示 eNB2的小区 2可以和 eNB3的小区 3为用户设备提 供双连接服务， 当指示信息为基站间双连接指示标识时该指示信息用于指示 eNB2可以和 eNB3为用户设备提供双连接服务。
可选地， 在上述图 1对应的实施例的基础上， 本发明实施例提供的控制用 户设备切换的方法的另一实施例中，所述获取用于控制用户设备切换的指示信 息， 可以包括：

向所述目标基站发送切换请求，所述切换请求中携带基站标识字段为所述 目标基站的 ECGI, 以使所述目标基站为所述用户设备提供连接服务。
本发明实施例中的指示信息可以为隐式指示信息，通过演进的通用陆地无 线接入网 ( evolved universal terrestrial radio access network, E-UTRAN ) 小区 标识（ Cell Global Identifier, ECGI )来指示， 如： 当 eNBl获取到 eNB2提供的 两个 ECGI时， 一个为 ECGI1 , —个为 ECGI2, 当 ECGI1中的基站标识字段与 eNB2的基站标识相同， ECGI2中的基站标识字段与 eNB3的基站标识相同时， eNBl就可以获知 eNB2和 eNB3可以为 UE提供双连接服务。 这样， 在控制 UE切 换时， 就可以控制 UE切换到 eNB2和 /或 eNB3。
