Description

获取位置更新策略、 拒绝位置更新和寻呼的方法和设备 本申请要求 2009年 5月 20日递交的申请号为 200910143313.1、发明名称为"获取位置 更新策略、 拒绝位置更新和寻呼的方法和设备"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
本发明实施例涉及网络通信技术, 尤其涉及 MTC (Machine Type Communications; 机 器类型通讯)应用架构中的方法和设备。 背景技术
MTC应用指的是一个或者多个网元之间在不需要人为参与的情况下进行的网络通讯 (即, M2M应用) , 如交通控制与管理、 工厂监控、 远程抄表等应用。 针对大量的 MTC 应用, 移动网还是很有竞争力。 但是当前的移动网主要是针对 H2H (Human To Human; 人 对人)应用做的种种优化和建设, 对 M2M (Machine To Machine; 机器对机器)应用、 M2H (Machine To Human; 机器对人) 、 H2M (Human To Machine; 人对机器) 的优化和建设 非常少。 MTC应用中, 多个具有相同 MTC应用的 M2ME (Machine To Machine Equipment; 机器对机器设备, 本发明中我们用 UE代替)组成一个整体, 简称群(Group) , 网络运营 商或者行业用户可以将群作为一个整体进行管理或控制。例如电力行业的远程抄表应用,我 们可将上海市所有的电表组成一个群,网络运营商和电力行业用户可以将该群作为一个整体 进行移动性管理优化或者接入管理。 图 1给出一种 MTC应用的架构图, 随着技术发展, 以 后的网络架构图可能有所不同, 本发明对此不做限制。
如图 1所示, MTC应用的架构中主要包含移动性管理网元 10、 MTC Server (MTC应 用服务器) 20、 接入网网元 30、 HSS (归属用户服务器) 40几个逻辑功能体, 还包含至少 一个用户设备 UE 50。 其中移动性管理网元 10负责 NAS信令和 NAS信令加密以及漫游、 跟踪等功能, 分配用户临时身份标识、 安全功能等。 MTC Server 20即 MTC应用服务器, 可存储 M2ME (即 UE)或者群相关的数据或者信息。 HSS 40主要存储 UE或者群相关的签 约数据。
MTC应用中, 存在很多各种种类(Category) 的 MTC应用。 其中 MO Only (只进行 始发业务)指 UE只进行 UE主动发起的业务。 Low Data Usage (低数据应用)表示网络侧 和 UE有很少的数据交互或者 UE和网络侧在很长的时间段内不会有交互。 Low Mobility (弱 移动)表示 UE很少移动, 比如 UE位置固定或者游牧。
现有技术中采用 H2H的方式进行 UE的位置更新, 即当 UE位置发生变化时 UE会发 起位置更新流程告知网络侧 UE的位置,以便网络侧获知 UE的位置,进行寻呼和数据下发。 为了保证网络侧能够获知 UE的存在, UE会有规律的发起周期性位置更新流程。 在寻呼流 程中, 移动性管理网元在网络侧为 UE分配的位置(在 E-UTRAN网络中, 位置指跟踪区列 表; 在 UTRAN/GERAN网络中, 位置区指路由区或者位置区) 向所述位置对应的所有接入 网网元发起寻呼, 接入网网元针对所述位置对应的所有小区发起寻呼。
由于 MTC应用广泛, 所以会有大量的 M2M终端 UE出现。如果采用 H2H (Human to Human)的方式进行 UE的位置更新和寻呼, 不考虑 MTC应用的 UE或者群的特点, 则大 量的 UE会因为大量的位置更新信令和寻呼信令给网络侧造成严重的信令冲击,导致网络侧 负荷很高, 影响网络侧的正常运行。 发明内容

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,本领域普通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。
下文中以图 1所示的 MTC应用架构为例来描述本发明的实施例。 应注意, 随着技术 发展, 该架构可以有所变化, 因此 MTC应用架构不对本发明的范围构成限制。 图 2是示出根据本发明实施例的获取位置更新策略的方法 100的示意流程图。 该方法 100可以由图 1中的移动性管理网元 10或接入网网元 30来执行。
具体地, 在 S1010, 移动性管理网元 10或接入网网元 30获取用户设备 UE 50的机器 类型通讯的类型信息 MTC Type (也可以描述为 MTC Category (MTC种类) , 本发明中其 它地方同样处理) , 并根据所获取的 MTC Type来设置位置更新策略。 或者, 在 S1010, 移 动性管理网元 10或接入网网元 30可直接从服务器获取用户设备 UE 50的位置更新策略。
然后, 在 S1020, 移动性管理网元 10或接入网网元 30将位置更新策略发送给 UE 50。 应注意, 这里的用户设备 UE 50可以是多个, 并且可以组成群以作为一个整体进行管理或 控制。 在此情况下, 群的 MTC Type可以为 UE 50的 MTC Type。 下面, 结合具体例子描述根据本发明实施例的获取位置更新策略的方法 100。应注意, 这些例子仅仅是为了更清楚的描述本发明实施例的原理而不是要限制本发明的范围。 实施例一
首先描述本发明实施例中使用的各个术语。
本发明实施例中使用的"网络侧 "包括但不限于移动性管理网元、 HSS、 MTC Server或 者其他用于下发位置更新策略的服务器(例如,本发明实施例中下发位置更新策略的服务器 由 MTC Server或者 HSS代替, 可以统一称为 "服务器") , 本发明不对 MTC Server的名称 或用于下发位置更新策略的服务器的名称作任何限制。 本发明实施例中使用的"位置更新策略 "包括但不限于如下几种策略:
A、 网络侧动态设置大于或者等于 MTC应用的运行周期的周期性位置更新 Timer (定 时器)值, 其中 MTC应用的运行周期指的是 UE 50或者群发生 MTC应用的时间间隔。 例 如远程抄表中, 如果行业用户要求电表一个月上报一次数据, 则这里的 MTC应用的运行周 期可以是一个月, 网络侧为 UE 50或者群设置的周期性位置更新定时器为一个月或者一个 半月。 移动性管理网元 10将设置的周期性位置更新 Timer值在 NAS消息中带给 UE 50。
B、 网络侧设置去激活位置更新功能, 即网络侧设置 Low Mobility或者 MO Only或者 Low Data Usage的 UE 50或者群不执行位置更新功能, 具体如下: UE 50或者群的位置发生 变化, UE 50或者群内所有 UE 50可以不执行位置更新流程, 或者 UE 50或者群内所有 UE 50可以不执行周期性位置更新功能。
具体地, UE 50获取去激活位置更新功能的具体实现为, 移动性管理网元 10在 NAS 消息中携带指示信息通知 UE 50或者群去激活位置更新功能, 该指示信息的具体表现形式 包括但不限于以下方式。 方式一: 移动性管理网元在 NAS消息中携带信元 Disabled LAU Function (去激活位置更新功能),若此信元为 1,表示去激活位置更新功能,若此信元为 0, 表示位置更新功能正常(例如 UE 50的位置发生变化时, UE 50会发起位置更新流程) 。方 式二:移动性管理网元在 NAS消息中携带信元 Enabled LAU Function (激活位置更新功能), 若此信元为 1, 表示 UE 50的位置更新功能正常(例如 UE 50的位置发生变化时, UE 50会 发起位置更新流程) 。 若此信元为 0, 表示网络侧去激活位置更新功能。 方式三: 移动性管 理网元在 NAS 消息中的临时标识信元(在 E-UTRAN 网络, 临时标识信元指 GUTI, 在 UTRAN/GERAN网络, 临时标识信元指 P-TMSI)的保留位(或者其他信元的保留位)设置 为 Disabled LAU Function, 保留位设置为 1, 表示去激活位置更新功能, 保留位设置为 0, 表示位置更新功能正常。方式四: 临时标识信元的保留位(或者其他信元的保留位)设置为 Enabled LAU Function,保留位设置为 1, 表示位置更新功能正常, 保留位设置为 0, 表示去 激活位置更新功能。 方式五: 移动性管理网元发送 NAS消息 Disabled LAU Message (去激 活位置更新消息)或者 Enabled LAU Message (激活位置更新消息)发送给 UE 50, UE 50 收到此消息后, 根据消息类型即可获知 UE 50的位置更新功能被去激活或者激活, 本发明 不对此消息名称作任何限制。 方式六: 移动性管理网元如果要去激活某 UE 50的位置更新 功能, 移动性管理网元在 NAS消息中携带信元 Disabled LAU Function, UE 50收到该信元 后表示去激活位置更新功能, 即 UE 50不执行周期性位置更新流程或者由于位置变化导致 的位置更新流程;如果移动性管理网元在 NAS消息中没有携带信元 Disabled LAU Function, UE 50没有收到所述信元,即 UE 50可以根据周期性位置更新 Timer值执行周期性位置更新 流程; 或者当 UE 50位置变化时, UE 50可以发起位置更新流程。去激活位置更新功能的具 体表现形式不对本发明实施例的范围构成限制。
C、 网络侧设置去激活周期性位置更新功能。 该功能可以通过网络侧设置周期性位置 更新 Timer值为零来实现。移动性管理网元 10可以将周期性位置更新 Timer值在 NAS消息 中带给 UE 50。
D、网络侧静态配置位置更新策略,例如 UE 50或者群的位置更新策略固定配置在 HSS 或者 MTC Server或者其他服务器中。比如 MO Only类型的 UE 50或者群, 网络侧静态配置 去激活位置更新功能或者去激活周期性位置更新功能。 Low Mobility类型的 UE 50或者群, 网络侧静态配置去激活位置更新功能。 Low Data Usage类型的 UE 50或者群,网络侧上静态 配置周期性位置更新时长为某一特定的数值。移动性管理网元从 HSS或者 MTC Server或者 其他服务器中获取 UE 50或者群的位置更新策略, 移动性管理网元在 NAS消息中将位置更 新策略带给 UE 50。
本发明实施例中使用的" NAS消息"包括但不限于 Attach Accept (附着接受)消息、 TAU Accept (跟踪区更新接受) 消息、 LAU Accept (位置更新接受) 消息、 RAU Accept (路由 区更新接受)、 Attach Reject (附着拒绝)、 TAU Reject (跟踪区更新拒绝)或者 LAU Reject (位置更新拒绝) 、 GUTI Reallocation Command (全球唯一临时标识重分配命令)等。
本发明实施例中使用的"移动性管理网元"包括但不限于: 在 E-UTRAN网络中的移动 性管理网元指 MME; UTRAN/GERAN网络中移动性管理网元指代 SGSN; 非 3GPP网络的 移动性管理网元指代接入网关 AGW, 即在 WLAN网络中的移动性管理网元指 ePDG中的 移动性管理的逻辑功能, 在 WiMAX网络, 移动性管理网元指代 ASN GW, CDMA网络中, 移动性管理网元指代 HRPD AN中移动性管理的逻辑功能。

本发明实施例中使用的" MTC Server"包括但不限于: M2M应用服务器,该服务器中包 含 UE 50或者群的信息或者数据, 本发明不对 MTC Server的名称作任何限制。 本发明实施 例中 UE 50的 MTC Type (M2M应用种类或者系统优化种类)可以存储在 MTC Server 20 中 (还可以将 UE 50的 MTC Type存储在 HSS中) 。 如果一组 M2M应用种类或者系统优 化种类相同的 UE组成一个群, 则群的 MTC Type存储在 MTC Server中 (群的 MTC Type 也可以存储在 HSS中) 。
本发明实施例中使用的" MTC Type"包括但不限于: MO Only、 Low Data Usage, Low Mobility。 本领域技术人员清楚, 很容易根据实际需要增加、 删除、 替换上述具体类型, 这 样的 MTC Type也落在本发明实施例的范围内。 本发明实施例中使用的" UE" (可能包括 M2ME),都是对 M2M应用的设备的一种称呼, 本发明实施例不受 UE的具体形式的限制,并且本发明实施例中全部用 UE来称呼 M2M应用 的设备。
本发明实施例中描述的" UE 50"包括: 单个 UE、 群内部分 UE或者群内所有 UE。 应用本发明实施例中使用的 "位置更新策略"的情形可包括但不限于: E-UTRAN网络中 的跟踪区 (TA)更新策略; UTRAN/GERAN 网络中的路由区 (RA) 更新策略或者位置区 (LA)更新策略; 非 3GPP网络中的位置区 (LA)更新策略。

将 Low Mobility或者 MO Only或者 Low Data Usage作为 UE 50的 MTC Type或者群 的 MTC Type存储在 HSS 40或者 MTC Server 20。在图 2的方法 100的 S1010,移动性管理 网元 10或接入网网元 30从 HSS 40或者 MTC Server 20中获取 UE 50的 MTC Type或者 UE 50所属的群的 MTC Type。 然后, 移动性管理网元 10或接入网网元 30根据 UE 50的 MTC Type或者群的 MTC Type, 给 UE 50设置位置更新策略。 在 S1020, 移动性管理网元 10或 接入网网元 30下发位置更新策略, UE 50即可按照此位置更新策略进行位置更新流程。
具体地,移动性管理网元 10可以在附着流程或者位置更新流程 (RAU、TAU或者 LAU) 等多个移动性管理流程中, 从 HSS 40或者 MTC Server 20中获取 UE 50的 MTC Type或者 群的 MTC Type o
图 3示出了根据本发明实施例一的获取位置更新策略的方法 100a的示意图。在此实施 例中, 移动性管理网元 10或接入网网元 30可以从 HSS 40或者 MTC Server 20或者其他服 务器获取 UE 50的 MTC Type或者群的 MTC Type。
在 S110a, UE 50发送附着请求或者位置更新请求 (LAU、 TAU或者 RAU) , 该请 求消息中携带 UE标识和 /或携带群标识。
在 S120a, 移动性管理网元 10发送签约数据请求消息到 HSS 40或者 MTC Server 20 或者其他服务器, 该签约数据请求消息中携带 UE标识和 /或群标识。 如果该签约数据请求 消息中携带 UE标识, 则在 SBOa中获取的签约信息为 UE 50的签约信息。如果该签约数据 请求消息中携带群标识, 则在 SBOa中获取的签约信息为 UE 50所属的群的签约信息, 所 述消息是用于请求获取 UE或者群的签约数据的消息,本发明不对此消息的具体名称作任何 限制。
在 S130a, HSS 40或者 MTC Server 20或者其他服务器根据 UE 50的标识和 /或群标识 获取 UE 50或者群的签约信息, HSS 40或者 MTC Server 20在签约数据响应消息带回 UE 50 或者群的签约信息。如果 UE 50或者 UE 50所在的群的 MTC Type在 HSS 40或者 MTC Server 20中签约,则移动性管理网元 10通过 SBOa中获取 UE 50的 MTC Type为 Low Mobility或 者 MO Only或者 Low Data Usage; 或者移动性管理网元 10通过 SBOa获取群的 MTC Type 为 Low Mobility或者 MO Only或 Low Data Usage。 可选地, 签约数据中还包含 UE 50或者 群的运行周期。 UE 50的运行周期是移动性管理网元 10用来动态确定 UE 50的周期性位置 更新 Timer的参数。 如果 MTC Type是针对群的签约数据, 移动性管理网元 10发现已经存 在 UE 50所属的群签约数据, 则移动性管理网元 10可以不到 HSS 40或者 MTC Server20中 获取签约数据, 所述消息是用于发送 UE或者群的签约数据的消息, 本发明不对此消息的具 体名称作任何限制。
移动性管理网元 10除了可以采用上述方法获取 UE 50或者群的 MTC Type,移动性管 理网元 10还可以根据 UE 50或者群的 MTC Type为 UE 50或者群设置位置更新策略。例如, Low Mobility类型的 UE 50或者群, 可去激活位置更新功能。 Low Data Usage类型的 UE 50 或者群, 可设置周期性位置更新时长为某一特定的数值。
可替换地, UE 50或者群的位置更新策略可以被配置在 HSS 40或者 MTC Server 20或 者其他服务器中。 比如 MO Only类型的 UE 50或者群, HSS 40或者 MTC Server 20或者其 他服务器上静态配置位置更新策略。 Low Mobility类型的 UE 50或者群, 网络侧静态配置去 激活位置更新功能。 Low Data Usage类型的 UE 50或者群,网络侧上静态配置周期性位置更 新时长为某一特定的数值。在此实施例中,移动性管理网元 10在 SBOa中从 HSS或者 MTC Server中获取 UE 50或者群的位置更新策略。所述位置更新策略可如实施例一所述。换句话 说,在该实施例中,移动性管理网元 10或接入网网元 30从服务器(HSS 40或者 MTC Server 20或者其他服务器)获取用于 UE 50或者群的位置更新策略, 其中所述位置更新策略被配 置在服务器中。 移动性管理网元 10或接入网网元 30将所述位置更新策略发送给 UE 50或 者 UE所属的群, 以便 UE 50或者群内 UE (群内一部分 UE或者群内全部 UE)根据该位置更 新策略进行位置更新。
移动性管理网元 10在 S140a中将所述位置更新策略带给 UE 50。例如, 可以借助附着 接受消息或位置更新消息将位置更新策略带给 UE 50。
后续 UE根据获取的位置更新策略执行相应的处理, 如, 如果位置更新策略为去激活 位置更新功能, 则 UE在位置发生变化时不执行位置更新流程。
本实施例中移动性管理网元根据 UE或者群的 MTC Type设置位置更新策略或者从 HSS、或者 MTC Server或者其他服务器中获取位置更新策略,然后将位置更新策略发给 UE 或者群内 UE,后续 UE或者群内 UE根据位置更新策略执行相应的处理,从而大大减少 MTC 应用中的位置更新流程, 从而降低网络的负荷, 保障网络的正常运行。
本实施例中 S120a-S130a可对应于图 2中方法 100的 S1010, S140a可对应于方法 100 的 S1020。 实施例二

下文中, 以移动性管理网元 10从 UE 50获取 UE 50携带的 MTC Type为例来描述根 据本发明实施例二的方法 100b。 应注意, 该方法 100b也可以由接入网网元 30执行, 只需 进行相应的调整即可。 当然, 本实施例的用户也可以为群内部分 UE或者群内所有 UE, 在 此仅以单个用户为例。
MTC Server 20或者 HSS 40或者其他服务器通过 OMA DM (Open Mobile Alliance Device Management, 开放移动联盟设备管理)或者 OTA (Over The Air, 空中下载)或者广 播或者组播的方式将 UE 50或者群的签约数据下发给 UE 50或者群内 UE (本实施例以 OMA DM的方式作为例子进行描述, 其他方式的实现形式与 OMA DM的方式相同) 。 该签约数 据中包含 UE 50的或者群的 MTC Type o UE 50或者群内 UE在后续接入网络时,携带 MTC Type。移动性管理网元 10根据 UE 50或者群内 UE携带的 MTC Type给 UE 50或者群内 UE 设置一个合适的位置更新策略。

上述实施例描述了 UE获取网络侧设置的位置更新策略的方法。 下面描述根据本发明 实施例的拒绝位置更新的方法, 即在 UE获取到所述位置更新策略后、没有按照网络侧设置 的位置更新策略发起位置更新请求的情况下,或者 UE没有获取到所述位置更新策略按照现 有方式发起位置更新请求的情况下,网络侧如何拒绝 UE的非法位置更新请求。通过此方法, 网络侧能够控制 UE的非法操作, 节约网络资源, 拒绝非法接入。
图 7示出了根据本发明实施例的拒绝位置更新的方法 200的示意流程图。 该方法 200 可以由图 1中的移动性管理网元 10或接入网网元 30执行。
具体地, 在 S2010, 移动性管理网元 10或接入网网元 30接收用户设备 UE 50发送的 位置更新请求。在 S2020,移动性管理网元 10或接入网网元 30根据网络侧为 UE 50设置的 位置更新策略, 拒绝 UE 50发送的位置更新请求, 向 UE 50发送位置更新拒绝消息。 所述 位置更新拒绝消息中可携带指示网络侧限制所述位置更新请求的指示信息,例如所述指示信 息可以为失败原因值、或者失败指示信息、或者拒绝消息, 本发明不对所述指示信息的表现 形式做任何限制。

在 S2010a, UE 50发起位置更新请求到移动性管理网元 10.该位置更新请求可以是周 期性位置更新请求或者由于位置变化所致的位置更新请求。
在 S2020a, 移动性管理网元 10根据位置更新策略来判断 UE 50发起的位置更新请求 的合法性。 如果该位置更新策略允许 UE 50的位置更新请求, 则移动性管理网元 10发送位 置更新接受消息给 UE 50; 否则移动性管理网元 10拒绝 UE 50的位置更新请求, 发送位置 更新拒绝消息。 该位置更新拒绝消息中携带指示信息以指示网络侧限制所述位置更新请求, 例如携带失败原因值 Restricted for LAU strategy。 通过此原因值告知 UE 50网络侧限制所述 位置更新请求。 可选地, 移动性管理网元 10在位置更新拒绝消息中携带网络侧设置的位置 更新策略。 所述位置更新策略可以如前面实施例一所述。

在 S2010b, UE 50发起位置更新请求到接入网网元 30。该位置更新请求可以为周期性 位置更新请求或者由于位置变化所致的位置更新请求。
在 S2020b, 接入网网元 30根据位置更新策略来判断 UE 50发起的位置更新请求的合 法性。 如果位置更新策略允许 UE 50的位置更新请求, 则接入网网元 30继续将位置更新请 求消息发送给移动性管理网元; 否则接入网网元 30拒绝 UE的位置更新请求, 发送位置更 新拒绝消息。该位置更新拒绝消息中携带指示信息以指示网络侧限制所述位置更新请求,例 如携带失败原因值 Restricted for LAU strategy。 通过此原因值告知 UE 50网络侧限制所述位 置更新请求。 可选地, 接入网网元 30在位置更新拒绝消息中携带网络侧设置的位置更新策 略。 所述位置更新策略可以如前面实施例一所述。
应注意, 方法 200b不对位置更新策略的获取 /设置方法进行任何限制, 可按照上面描 述的方法 100、 100a, 100b, 100c, 100d来获取位置更新策略, 也可以按照其他方法获取 / 设置位置更新策略。
例如: 如果在 UE 50接入网络时, 接入网网元 30为 UE 50设置的位置更新策略为去 激活位置更新功能并将所述位置更新策略发送给 UE 50 (例如, 前面实施例三描述的相应方 法) 。 之后 UE 50位置发生改变时, 发送位置更新请求。 接入网网元 30收到位置更新请求 后, 查询网络侧为 UE 50设置的位置更新策略。 由于网络侧为 UE 50设置的位置更新策略 为去激活位置更新功能, 所以接入网网元 30发送位置更新拒绝消息。 该位置更新拒绝消息 中携带位置更新失败原因值 Restricted for LAU strategy, 此原因值用于告知 UE网络侧限制 所述位置更新请求。失败原因值的具体名称不对本发明实施例的范围构成限制。可选地,位 置更新拒绝消息中可携带网络侧为 UE 50设置的位置更新策略。
再例如: 如果在 UE 50接入网络时, 接入网网元 30为 UE 50设置的位置更新策略为 去激活周期性位置更新功能并将所述位置更新策略发送给 UE 50 (例如, 前面实施例描述的 相应方法) 。 UE 50在周期性定时器超时时, 发送位置更新请求。 接入网网元 30收到位置 更新请求后, 查询网络侧为 UE 50所设置的位置更新策略。 由于位置更新策略为去激活周 期性位置更新功能, 所以接入网网元 30发送位置更新拒绝消息。 该位置更新拒绝消息中携 带指示信息以指示网络侧限制所述位置更新请求。指示信息的具体表现形式对本发明实施例 的范围不构成限制。 可选地, 位置更新拒绝消息中可携带网络侧为 UE 50设置的位置更新 策略。
图 8和图 9所示的拒绝位置更新请求的方法可节约网络资源, 拒绝非法接入。
本实施例中网络侧拒绝 UE或者群内 UE非法位置更新,可以大大减少 MTC应用中的 非法位置更新流程, 从而提高网络安全, 保障网络和用户业务的正常运行。

应注意, 位置更新设备 600和 600'不一定被集中布置在一个设备中, 也可以根据需要 而分布在通信系统中的不同设备上。
位置更新流程是为了让网络侧获知 UE的具体位置以便可以寻呼到 UE或者下行数据 的下发, 周期性位置更新流程是为了向网络侧证明 UE的存在。
网络侧获取到 UE或群的 MTC Type或者位置更新策略后, Low Mobility的群或者 UE由于位置固定或者游牧, 所以位置变化导致的位置更新流程可以去激活, 简化 MTC实 现同时减轻网络负荷。 并且由于 UE或者群的位置固定或者游牧, 所以网络侧寻呼 UE时可 以以一个相对小的位置来寻呼 UE, 大大减小了网络侧寻呼量。
对于 Low Data Usage的群或者 UE和网络侧交互很少,所以网络侧不需要时时获知 UE 的存在。 因此适当增加这类 UE或者群的周期性位置更新的周期可使得 UE和网络交互信令 大大减小。 由于 M2M UE应用广泛, UE数量庞大, 这些位置更新策略能够很好的减轻网 络负荷并且不影响 UE正常进行业务。
对于 MO Only的群或者 UE, 所有的终端在发起业务时都是 UE主动发起的, 因此去 激活位置更新流程和周期性位置更新流程可以大大减轻大量 UE和网络之间的信令交互,从 而大大减轻了网络负荷。
