Description

终端移动性管理的方法、网络设备及终端 技术领域
本发明实施例涉及通信领域，特别是涉及一种终端移动性管理的方法及网络设备。
背景技术
移动性管理(MM，Mobile Management)是对终端位置信息、安全性以及业务连续性等方面的管理，努力使终端与通信网络的联系状态达到最佳，进而为各种网络服务的应用提供保证。
现有GSM/WCDMA/LTE的终端移动性管理都是基于终端对基站的下行导频信号/下行参考信号的测量或测量上报进行的。例如，在LTE系统中，空闲态终端的移动性是由终端对基站的下行参考信号的接收强度/质量进行测量，并根据基站选择或基站重选准则选择合适的基站驻留；连接态终端的移动性是由终端对基站的下行参考信号的接收强度/质量进行测量，并进行上报，由服务基站根据一定准则进行切换判决，并下发给终端切换指令，完成切换。
超密集组网是5G网络重要的技术发展方向。未来5G的网络密集程度将可能达到现有4G网络的10倍甚至更高。也就意味着，相对于4G系统，未来5G的终端将有可能同时检测到10倍甚至更多的基站数量。因此，若采用4G中基于下行导频信号/下行参考信号测量的移动性管理策略，将可能导致终端的测量处理开销大、耗电高，以及频繁的基站重选或切换，用户体验不好。

对于本发明实施例中一些设备的介绍如下：
信标基站(Anchor BS)和移动性管理服务器(Mobil e Management Server，MMS)：若某一覆盖区域内有超远覆盖或基础覆盖的基站存在时，通常将该基站定义为信标基站，也可称移动性管理服务器；若该覆盖区域内没有超远覆盖或基础覆盖的基站存在时，则会在核心网侧部署移动性管理服务器，控制其覆盖区域内的多个基站。移动性管理服务器可以位于核心网的某个网元，也可以位于无线网的某个网元；当某个区域内有一个超远覆盖的基站时，通常可以将其当做该区域的移动性管理的锚点，也就是控制器，即移动性管理服务器，且由于它本身也是一个基站，也可以称为信标基站；当某个区域内所有基站的覆盖范围几乎相同，没有这种锚点性质的超远覆盖的基站时(即没有信标基站)，则需要一个移动性管理服务器连接该区域内的各个基站，控制各第一基站(下文解释)接收终端发送的上行信号，并为终端配置服务基站。
第一基站：由信标基站和移动性管理服务器根据规则配置，接收终端发送的上行信号，对上行信号测量得出上行信号测量信息并发送给信标基站和移动性管理服务器。
服务基站：服务基站都是信标基站和移动性管理服务器为空闲态终端配置的提供通信服务的基站。
图1为本发明实施例的应用环境示意图，如图1所示，本发明实施例可应用于移动通信网络中，实现第一网络设备200对终端100的移动性管理。第一网络设备200可以是信标基站或移动性管理服务器中的设备，第一网络设备位于基站实体内，集成了服务器的功能，通过接口获取终端信号。终端可以是智能手机等具有移动通信功能的移动终端。第二网络设备300可以是第一基站中的设备，对终端发送的上行信号进行测量，并将上行信号测量信息发送给第一网络设备200。
首先，对本发明实施例的整体方案流程进行详细说明。图2为本发明实施例的终端移动性管理的方法的流程图。图3为通信网络中基站分布及移动性管理示意图，如图3所示，5G网络的超密集组网将使终端可能同时检测到相比4G网络10倍甚至更多的基站数量。图中A为基础覆盖小区，B-F为提供超大带宽的小小区。A具有最广的覆盖范围，作为一片基站覆盖区内的信标基站，负责根据多个基站上报的根据接收到终端发送的上行信号测量信息，提供终端移动性管理服务，为终端进行移动性配置，例如确定终端的服务基站和对终端进行位置跟踪。
如图2所示，该方法包括：
步骤101.信标基站(或移动性管理服务器)向终端发送用于空闲态终端的上行信号配置信息。
需要说明的是，信标基站的广播信息中有很多分区，有的分区是针对所有状态终端的(空闲态、准连接态、连接态)，有的分区是针对空闲态的，有的分区是针对准连接态或连接态的，而这些分区很可能是信标基站在同一广播信息中发送的，不同状态的终端去不同分区解析自己 所需的信息。所以信标基站发送的广播信息中有可用于空闲态终端的内容，例如用于空闲态终端的上行信号配置信息。
步骤102.终端根据上行信号配置信息发送上行信号。
上行信号是终端在没有业务请求时的空闲状态下发送的，空闲态终端根据上行信号配置信息发送上行信号后，由接收到上行信号的第一基站对上行信号进行测量，得到上行信号测量信息。第一基站测量出上行信号测量信息后先保存，以备后续终端有业务请求时需要上报。
步骤103.第一基站接收终端发送的上行信号，测量得出上行信号测量信息。
第一基站可以是一个或多个，是信标基站根据规则预先配置好的，例如信标基站选择5公里范围内可以实现通信的无缝连接的一些基站组成第一基站。或者，在一些极端情况下，只有信标基站本身符合第一基站的选择条件，或者移动性管理服务器只指配一个第一基站(超远覆盖的基站，即信标基站)做上行信号的测量。
步骤104.第一基站向信标基站上报上行信号测量信息。
只有存储有该终端标识的上行信号测量信息的第一基站才向信标基站发送对终端的上行信号测量信息，也即对该终端的上行信号进行了测量的第一基站才会发送上行信号测量信息。
步骤105.信标基站向核心网上报信标基站内的空闲态终端标识列表。
步骤106.核心网接收终端下行业务请求，根据终端标识确定终端所驻留的信标基站。
当有针对该终端的下行业务请求后，核心网会根据终端标识确定终端所驻留的信标基站。
步骤107.核心网向所确定的信标基站发送包含终端标识的寻呼消息。
步骤108.信标基站根据第一基站上报的对终端的上行信号测量信息，确定终端的服务基站。
信标基站根据特定的准则从第一基站中选择准服务基站，该终端可能位于多个第一基站的覆盖范围的交叠区，可能会有多个第一基站能够接收到终端的上行信号，但是最佳的服务基站只有一个，可以根据特定的准则选择出服务基站。
步骤109.信标基站向确定的服务基站发送包含终端标识的业务建立请求。
步骤110.服务基站向信标基站发送业务建立请求响应。
步骤111.信标基站向终端发送寻呼消息。
步骤112.信标基站向核心网发送寻呼响应。
步骤113.核心网向服务基站发送下行业务。
步骤114.服务基站向终端发送下行业务数据。
相比现有技术中基于下行导频信号/下行参考信号测量的移动性管理方法，本发明实施例在终端侧不涉及基站重选或切换，终端只需要发送上行信号，由信标基站或移动性管理服务器的第一网络设备根据第一基站发送的上行信号测量信息为终端进行移动性配置，给终端配置服务基站，降低了终端对系统内和系统外的基站的下行信号的测量开销和能耗，不需要进行频繁的基站重选或切换，且终端可不考虑网络的覆盖情况及负载情况，由第一网络设备来决定给终端服务的基站，实现了5G网络对网随人动的需求，使终端有来自网络侧的下行业务请求时，能快速为终端分配服务基站。
本发明第一实施例提供了一种终端移动性管理的方法，该方法应用于信标基站或移动性管理服务器中的网络设备，图4为本发明第一实施例的终端移动性管理的方法的流程图。如图4所示，该方法包括：
步骤201.第一网络设备向终端发送用于空闲态终端的上行信号配置信息。
其中，上行信号为参考信号、信标信号和随机接入请求信号中的一种或多种。参考信号、信标信号、随机接入请求信号的核心信息包括发送端(终端)和接收端(第一基站)双方已知的序列，以供第一基站进行能量检测和/或信道估计。上述信号还可以在已知序列后携带额外的信息，例如，随机接入请求中可以加入终端的标识信息。
步骤202.第一网络设备接收第一基站发送的上行信号测量信息，其中所述上行信号测量信息为第一基站接收由终端根据所述上行信号配置信息发送的携带终端标识的上行信号后测量得出的信息。
步骤203.第一网络设备根据所述上行信号测量信息为所述终端进行移动性配置，其中所述移动性配置为网络侧有所述终端下行业务到达时，给终端配置服务基站，以使终端在所述服务基站接收寻呼消息。
步骤201中，第一网络设备发送上行信号配置信息具体包括如下步骤：
第一网络设备配置用于空闲态终端的上行信号的发送周期或触发事件类型；其中，触发事件包括所述终端的服务基站或信标基站的下行参考信号强度或下行参考信号质量低于第一预设门限值，或者终端距离上一次发送上行信号的时间间隔超过第二预设门限值；
第一网络设备向终端发送用于空闲态终端的上行信号的发送周期配置信息或上行信号的触发事件类型配置信息或指向所述终端的上报指令。
因此，终端发送上行信号可以采用如下方式中的任意一种：
1.终端按照第一网络设备配置的上行信号的发送周期发送上行信号。
其中，上行信号的发送周期可以是第一网络设备根据所述终端的移动速度预先配置所述终端的上行信号的发送周期。例如，终端的移动速度较快时，则第一网络设备配置较短的上行信号的发送周期，反之当终端的移动速度较慢时，则第一网络设备配置较长的上行信号的发送周期。
2.终端在发生第一网络设备配置的触发事件时发送上行信号。
其中，触发事件包括所述终端的服务基站或信标基站的下行参考信号强度或下行参考信号质量低于第一预设门限值，或者终端距离上一次发送上行信号的时间间隔超过第二预设门限值。第一预设门限值和第二预设门限值可以根据实际情况进行设定。当终端的服务基站或信标基站的下行参考信号强度或下行参考信号质量低于第一预设门限值时，可能是终端已位于服务基站或信标基站的边缘位置或者存在其他因素，此时需要进行基站切换，终端发送上行信号以使第一网络设备为终端进行基站切换等移动性配置。当终端距离上一次发送上行信号时间间隔超过第二预设门限值时，说明终端已经较长时间没有进行基站重选或基站切换，此时可能需要重新为基站进行移动性配置，以使第一网络设备为该终端选择最适合的基站提供服务。
3.终端在第一网络设备下发指向终端的上报指令时发送上行信号。
例如，另一终端发起对某一终端的连接需求时，第一网络设备会向被连接的终端下发上报指令，此时，由该终端根据收到的上报指令发送上行信号，以使第一网络设备为终端进行基站选择等移动性配置，满足另一终端与该终端之间的通讯需求。
此外，第一网络设备还可以配置用于空闲态终端的发送上行信号的资源位置和上行信号所包含的序列信息；然后向终端发送用于空闲态终端的发送上行信号的资源位置配置信息和上行信号所包含的序列信息配置信息。
其中，上行信号所包含的序列信息可以是参考序列、特殊序列、随机序列或已知序列等，序列信息主要用于终端标识，例如1024字节的序列长度代表某一特定的终端。
第一网络设备配置的终端发送上行信号的资源位置、上行信号所包含的序列信息，以及上行信号的发送周期或上行信号发送的触发事件类型是在信标基站的广播信息中发送的。当然，还可以在信标基站的控制信息中或者最佳业务请求接入基站在特定的资源位置进行发送。
在步骤201之前，该方法还可以包括如下步骤：
第一网络设备配置所述第一基站，以使第一基站接收到由终端根据所述上行信号配置信息发送的携带终端标识的上行信号后测量得出上行信号测量信息。
第一网络设备在接收到终端发送的携带终端标识的业务请求信息后向所述第一基站发送携带终端标识的测量上报信息指令，以使第一基站向第一网络设备发送所述上行信号测量信息。
第一网络设备可以采用如下方式中的一种或多种为所述终端进行移动性配置：
1.根据所述上行信号测量信息，选择信号强度最高或者信号质量最高的基站作为所述终端的服务基站；
2.根据所述上行信号测量信息，选择信号强度最高或者信号质量高于第三预设门限值的基站作为所述终端的服务基站；
第三预设门限值可以根据实际情况进行设定。可以选择出数个符合条件的基站作为终端的服务基站，而不仅仅是选择一个基站作为终端的服务基站，为终端的通信提供更丰富的基站选择。
3.根据所述上行信号测量信息和第一基站的负载情况，选择信号强度或信号质量高于第四预设门限值且负载最低的基站作为所述终端的服务基站。
第四预设门限值可以根据实际情况进行设定。可以进一步结合负载选择基站，例如信号强度或信号质量高于第四预设门限值且其负载最低的基站，适合提供给终端作为服务基站，此时可以选择该基站作为目标基站。
终端的状态可以为空闲态、连接态或准连接态。对于空闲态终端，第一网络设备将配置的 候选服务基站或服务基站通知空闲态终端，以使空闲态终端根据所述候选服务基站或服务基站发送上行业务请求；或者，第一网络设备配置寻呼消息，将配置的候选服务基站或服务基站以及寻呼消息通知空闲态终端，其中所述寻呼消息包含终端标识，所述寻呼消息是由信标基站或候选服务基站或服务基站发送的；对于连接态或准连接态终端，第一网络设备将配置的服务基站通知连接态或准连接态终端，以使连接态或准连接态终端与所述服务基站建立连接。
具体地，第一网络设备为终端进行移动性配置时，对于空闲态终端来说，信标基站确定终端的最佳寻呼基站或寻呼片区(下行业务请求到达时需精确寻呼)和/或最佳业务请求接入基站(由上行业务发起)。其中，最佳寻呼基站或寻呼片区由信标基站确定，并当下行业务请求到达时，在最佳寻呼基站或寻呼片区内发送包含终端标识的寻呼信息；最佳业务请求接入基站由信标基站确定，并在信标基站的广播信息或控制信息中，或者最佳业务请求接入基站在特定的资源位置进行发送，并当有上行业务请求时，终端在最佳业务请求接入基站发起业务请求。终端无需进行空闲态下的基站重选测量，终端的位置网络侧可判断，当有业务到达时，可精确地发送寻呼信息或发起业务请求，大幅降低终端测量的复杂度和功耗。
对于连接态或准连接态的终端来说，信标基站确定终端的候选服务基站或候选服务基站集合、服务基站或服务基站集合、切换基站或切换基站集合，并在信标基站的广播信息或控制信息中，或由移动性管理服务器在特定基站或特定资源位置发送终端对应的候选服务基站标识或候选服务基站集合标识序列、服务基站标识或服务基站集合标识序列、切换基站标识或切换基站集合；终端只需与候选服务基站或候选服务基站集合、服务基站或服务基站集合进行下行同步，并接收数据，或者对切换基站或切换基站集合进行下行同步，并发起切换请求。这样，无需进行连接态的下行本系统、异系统测量，大幅降低了终端的测量复杂度和功耗。
需要说明的是，第一网络设备为终端进行移动性配置时，为终端配置的服务基站通常为一个，当然也可以是基站组，当终端有业务请求时，从基站组中根据预设的规则选择一个基站进行服务。因此，在一些实施例中，第一网络设备还可以根据所述终端的移动方向和移动速度，预先为所述终端配置服务基站集合服务基站集合。图5是本发明实施例在列车应用场景的示意图，如图5所示，在高速公路或高铁场景中，终端处于移动状态，可以根据终端的移动方向和移动速度预先为终端配置服务基站集合。其中，终端的移动方向和移动速度可由终端在参考信号、信标信号和随机接入请求中携带，或由信标基站或移动性管理服务器根据多个基站对终端的参考信号、信标信号和随机接入请求信号进行联合定位和速度估计获知。具体地，可根据多个基站上报的终端的上行参考信号、信标信号和随机接入请求对终端的移动方向和/或移动速度进行估计，或者在终端的参考信号、信标信号和随机接入请求中携带终端的移动方向和/或移动速度信息。信标基站或移动性管理服务器根据终端的移动方向和/或移动速度信息，为终端配置最佳寻呼基站或片区序列，和/或最佳业务请求接入基站序列。终端在移动时：当有下行业务请求到达时，信标基站在最佳寻呼基站或寻呼片区内发送包含终端标识的寻呼信息；当有上行业务请求时，终端在最佳业务请求接入基站发起业务请求。在既定线路上提前预先给终端精确地配置上述基站，大幅降低接入或切换时延，提升用户体验。
第一网络设备对服务基站集合中的各个基站进行优先级标识，以使终端选择优先级高的服务基站接入。或者，由终端在服务基站集合或切换基站集合中随机选择准服务基站或服务基站接入或切换基站切换；或者，由终端对服务基站集合或切换基站集合中的基站进行下行参考信号测量，选择下行参考信号接收强度最高或下行参考信号质量最高的准服务基站或服务基站接入或切换基站切换。
本发明实施例中，终端发送上行信号(也即上报)时不必考虑由哪个基站接收，以及接收是否会随着终端的移动性而中断。终端只需按照信标基站的指示去上报即可，而信标基站接收并根据第一基站对上报的测量结果去判断适合终端的服务基站或服务基站组。当有下行业务到达时，信标基站会确定在哪个基站或哪些基站下发寻呼指令。
