Description

一种检测用户设备接近的方法和设备 本申请要求在 2013年 8月 26日提交中国专利局、 申请号为 201310376959.0、 发明名称为
"一种检测用户设备接近的方法和设备"的中国专利申请的优先权,其全部内容通过引用结合在 本申请中。 技术领域 本申请涉及无线通信技术领域, 特别涉及一种检测用户设备接近的方法和设备。 背景技术 在 LTE ( Long Term Evolution, 长期演进) 系统中, 釆取的是网络集中控制的方式, 即 UE (用户设备 ) 的上下行数据都在网络的控制下进行发送和接收。 UE和 UE之间的通 信, 是由网络进行转发和控制的。 UE与 UE之间不存在直接的通信链路, UE也不允许自 行发送上行数据, 参见图 1。
D2D ( Device-to-Device ), 即用户设备直通技术, 是指邻近的用户设备可以在近距离 范围内通过直连链路进行数据传输的方式, 不需要通过中心节点 (即基站)进行转发, 如 图 2所示。 D2D技术本身的短距离通信特点和直接通信方式使其具有如下优势:
用户设备近距离直接通信方式可实现较高的数据速率、 较低的延迟和较低的功耗; 利用网络中广泛分布的用户设备以及 D2D通信链路的短距离特点,可以实现频谱资源 的有效利用;
D2D的直接通信方式能够适应如无线 P2P ( Peer to Peer, 点对点)等业务的本地数据 共享需求, 提供具有灵活适应能力的数据服务;
D2D 直接通信能够利用网络中数量庞大且分布广泛的通信用户设备以拓展网络的覆 盖范围。
在 D2D通信模式中,用户设备和用户设备之间允许进行一定的直接通信,这些直接通 信链路可以是在网络控制或者辅助下建立起来的。用户设备和用户设备之间进行 D2D通信 的基础是对靠近的用户设备进行发现。
在一般的场景中, 两个互相通信的 UE可以由于彼此的接近, 将原本通过网络传输的 通信链路转化为本地的直接通信链路, 从而节省了大量的带宽和网络效率。 或者由于两个 UE的相互靠近, 而产生了通信的需求, 在这种接近的距离情况下, UE之间可以利用直接 通信链路进行通信来获得稳定高速低廉的通信服务。 例如公安, 消防, 救护等场景。
现有技术中用户设备间直接通信技术, 在检测接近的用户设备时, 需要发送方周期性 发送 "信标" 信号, 而接收方需要不断尝试解调 "信标" 信号。 如果接收方和发送方的距 离超过 "信标" 信号传输范围, 由于接收方无法接收到 "信标" 信号, 因此无法发现发送 方。
目前的方案中在检测接近的用户设备时, 要求发送方不断发送 "信标" 信号, 接收方 不断尝试解调 "信标"信号, 而很多 "信标"信号都不会被接收方接收到, 造成资源浪费, 并且发送方需要不断发送, 接收方需要不断尝试接收, 增大用户设备耗电量。 发明内容 本申请提供一种检测用户设备接近的方法和设备, 用以解决现有技术中存在的进行 D2D通信过程中, 在检测接近的用户设备时, 会造成资源浪费, 增大用户设备耗电量的问 题。

其中, 本申请实施例的小小区可以是 Pico cell (微小区)、 He B ( Home eNodeB, 家 庭式基站)等。
在实施中, 根据用户需要可以设置接近检测功能, 只有开启接近检测功能才可以进行 接近检测。
具体的, 网络侧设备在确定第一用户设备和第二用户设备中至少有一个用户设备开启 接近检测功能后, 根据第一测量结果和第二测量结果, 判断第一用户设备和第二用户设备 是否接近。
其中, 网络侧设备接收第一用户设备的服务基站发送的第一测量结果, 以及接收第二 用户设备的服务基站发送的第二测量结果。
较佳地, 若第一用户设备开启接近检测功能, 则第一用户设备的服务基站还可以将表 示第一用户设备开启接近检测功能的信息发送给网络侧设备;

在实施中, 还可以设定指定用户设备之间可以进行接近检测。

其中, 网络侧设备可以仅对第一用户设备的上下文进行判断, 并根据判断结果确定是 否判断第一用户设备和第二用户设备是否接近。 网络侧设备也可以仅对第二用户设备的上 下文进行检测, 并根据判断结果确定是否判断第一用户设备和第二用户设备是否接近。 网 络侧设备还可以对第一用户设备的上下文和第二用户设备的上下文进行检测, 并根据判断 结果确定是否判断第一用户设备和第二用户设备是否接近。
在实施中, 网络侧设备还可以接收第一用户设备的服务基站发送的第一用户设备的服 务基站的信息; 以及接收第二用户设备的服务基站发送的第二用户设备的服务基站的信 息。以便网络侧设备触发后续的信令过程。例如 e Bl将 UE1的测量上报通知网络侧设备, 和网络侧设备发现 UE1和 UE2靠近是两个独立的过程,因此网络侧设备在发现 UE1和 UE2 靠近后, 需要根据 UE上下文中保存的 UE当前服务基站信息, 确定发送后续 "消息" 针 对的目标基站。 (也就是说网络侧设备本身是以 UE ID为索引保存信息的)。
较佳地, 网络侧设备在确定第一用户设备和第二用户设备接近后, 向第一用户设备的 服务基站发送接近指示消息;

下面列举一个集中式例子对本申请的方案进行详细说明。
集中式例子、 基于中心设备方式的 UE接近检测过程。
步骤 1 : eNBl根据核心网指示, 为激活 UE接近检测功能的 UE1配置针对 UE1当前 服务小区及其邻小区的测量。
(例如 eNBl触发 UE1周期性上 4艮对当前服务小区与相邻小区信号的测量结果)。 步骤 2: UE1根据 eNBl的配置, 周期性的将当前服务小区和邻小区的测量结果上报 给当前服务基站 eNBl。
步骤 3: eNBl将从 UE处获得的对当前服务小区及其相邻小区的测量结果上 4艮给接近 检测服务器( PDC ), 其中包含当前 UE的接近检测标识(这个标识表示 UE已经激活 UE 接近检测功能)、 当前 UE的服务基站信息以及 UE对当前服务小区和邻小区的信号强度的 测量结果。
步骤 4: PDC确定用户的上下文中的接近检测的目标(例如 UE1的签约信息中包含对 UE2的接近检测签约)。
比如 PDC可以通过与保存 UE签约信息的实体 (例如 HSS ( Home Subscriber Server, 归属签约用户服务器))进行交互, 得到 UE当前的签约信息。
步骤 5: PDC根据 UE1 当前服务小区和相邻小区的信号强度信息与 UE2当前服务小 区和相邻小区的信号强度信息的比较, 判断 UE1和 UE2是否相互靠近(例如 UE1测量到 的小区列表和 UE2检测到的小区一样则认为 UE1和 UE2相互靠近)。
步骤 6: PDC在判断出 UE2接近 UE1后将接近指示信息发送给 UE1当前的服务基站 eNB 1 , 并在接近指示消息中携带 UE 1的标识信息、 UE2的标识信息, 以及 UE2的服务基 站 e B2的信息。
在实施中, UE1 可能同时签约了针对多个目标 UE 的接近检测的目标, 例如针对 UE2/UE3/UE4...的接近检测的目标。 因此 PDC根据 UE1签约进行顺序检测。 如果 UE1签 约针对多个目标 UE, 比如 UE2/UE3/UE4均接近 UE1 , 则需要将这三个事件都指示给 UE1 当前的服务基站。
步骤 7: e Bl可以根据 UE2的标识信息和 eNB2的信息, 发起针对 UE2的业务建立 过程, 具体可以根据需要选择不同的建立过程, 其中 e B2的标识信息用于信令路由, 而 UE2的标识信息用于 e B2确定目标 UE。
比如 UE1的服务基站可以触发 UE1与 UE2建立直接的信令连接, 使 UE1和 UE2通 过无线接口进行直接通信过程。

下面列举一个分布式例子对本申请的方案进行详细说明。
分布式例子、 基于基站分布式的 UE接近检测过程。
步骤 1 : 基站 e Bl根据核心网指示, 为激活 UE接近检测功能的 UE1配置针对 UE1 当前服务 ' j、区及其邻小区的测量。
(例如 eNBl触发 UE1周期性上 4艮对当前服务小区与相邻小区信号的测量结果)。 步骤 2: UE1根据基站 eNBl的配置, 周期性的将当前服务小区和相邻小区的测量结 果上 4艮给当前服务基站 e B 1。
步骤 3: eNBl将 UE1的接近检测标识(这个标识表示 UE已经激活 UE接近检测功能)、 UE1对当前服务小区和相邻小区的测量结果通过 Push的方式发送给相邻基站。
eNBl选择目标基站时, eNBl可以将消息发送给所有与 eNBl管理小区有相邻关系的 基站; eNBl也可以根据 UE1的相邻小区测量结果, 将消息仅发送给相邻小区测量涉及的 基站。 步骤 4: e B2在从邻小区获得 UEl的接近检测标识信息后, 结合当前 e B2上保存 的 UE上下文确定接近检测的目标(例如 UE2的上下文信息中包括授权 UE1对 UE2的接 近检测)。
步骤 5: eNB2根据 UE1当前服务小区和邻小区的信号强度信息, 以及 UE2当前服务 小区和邻小区的信号强度信息的比较, 判断 UE1和 UE2是否相互靠近(例如 UE1测量到 的小区列表和 UE2检测到的小区一样则认为 UE1和 UE2相互靠近)。
步骤 6: e B2判决出 UE1和 UE2彼此靠近后 , 可以向 e Bl发起针对 UE1的服务的 建立过程, 具体可以根据需要选择不同的建立过程; 也可以将 UE1与 UE2相互靠近事件, 以及 UE2当前的服务小区信息通过接近指示消息通知 eNBl , 由 eNBl发起针对 UE2的业 务建立过程, 具体可以根据需要选择不同的建立过程。
例如, UE1的服务基站可以触发 UE1与 UE2建立直接的信令连接, 使 UE1和 UE2 通过无线接口进行直接通信过程; 同理, UE2的服务基站也可以触发 UE1与 UE2建立直 接的信令连接, 使 UE1和 UE2通过无线接口进行直接通信过程。
又例如,UE1和 UE2之间通过无连接的方式实现 UEl和 UE2在空口的之间相互通信, 在此过程中, 网络侧和 UE侧可以分别建立 UE1和 UE2之间的关联关系, 从而实现 UE1 和 UE2通过无线接口进行直接通信的目的。
在上述实施例的步骤 3中, eNBl也可以不将信息通过 Push的方式发送给相邻基站, 而是由 eNBl根据信息进行是否接近的判断, 具体判断过程与上述例子类似, 只是在判断 之后, 不需要将 UE1与 UE2相互靠近事件, 以及 UE2当前的服务小区信息通过接近指示 消息通知 eNBl的步骤。
