Description

用户终端的寻呼方法及系统、 用户终端、 寻呼网络 技术领域
本发明涉及缩小对用户终端( UE, User Equipment )的寻呼范围的技术, 尤其涉及一种扁平化架构下缩小对用户终端的寻呼范围的用户终端的寻呼 方法及系统、 用户终端、 寻呼网络。 背景技术
图 1为通用移动通信系统 ( UMTS , Universal Mobile Telecommunication System ) 的网络结构示意图, 如图 1 所示, 为寻呼方便, 运营商将一个或 多个小区组成一个位置区 (LA, Location Area ), 通过为 LA设置不同的编 码来区分, 这些 LA编码称为位置区码(LAC, Location Area Code ), 运营 商标识加上位置区码是全球唯一的。 位置区是用户终端非接入层(NAS , Non-Access-Stratum )移动性管理的最小区域, 对于电路交换( CS , Circuit Switch )业务来说是 LAC, 而对于分组交换(PS, Packet Switch )业务来说 是路由区码( RAC, Routing Area Code )。 UMTS系统中, 一个 RAC总是在 一个 LAC 范围内, 而且一个小区在某个域只会归属于一个位置区。 在 GERAN( GSM EDGE Radio Access Network )系统中,位置区的划分与 UMTS 系统相同。
目前现有技术中, 寻呼的过程是这样实现的:
在用户终端开机时, 或者用户终端在网络中移动而跨越位置区 (即从 一个位置区移动到另一个位置区) 时, 或者周期性地向网络侧发起位置更 新, 用户终端所发送的位置更新消息中包含有用户终端当前所驻留小区所 属的位置区信息。
MSC ( Mobile Switching Center ) /VLR ( Visitor Location Register )收到 用户终端的位置更新消息后 , 就能够确定用户终端所在的位置区并保存。 当网络侧需要与这个用户终端建立连接的时候, 则可以将用户终端位 置更新携带的位置区信息携带在寻呼消息中发送给该位置区归属的无线网 络控制器(RNC, Radio Network Controller ), 其中, 位置区归属的 RNC可 能有多个。 RNC收到寻呼消息后, 向本 RNC内归属于该位置区的所有小区 发送寻呼消息。
图 2为网络扁平化后的网络结构示意图, 如图 2所示, 网络扁平化即 把 BSC ( Base Station Controller ) /RNC的功能压缩到基站内, 这样基站就 和核心网直接相连。这时如果 MSC/VLR需要与某个用户终端建立连接,则 需要直接把寻呼消息发送给基站。众所周知,基站的数量比 RNC要多很多, 这样做将会导致 MSC/VLR与基站之间的寻呼消息激增,而寻呼消息的激增 势必会造成核心网的负荷过高, 并大大增加核心网和基站间交互信令的流 量。 UMTS网络中, 通常情况下, 一个 RNC可以管辖上千个基站, 假如一 个 RNC管辖 500个基站, 网络扁平化后, 核心网将要与这 500个基站直接 相连, 原来核心网与 RNC之间的寻呼消息将要放大 500倍, 这个消息量的 增加是相当惊人的。 目前, 现有技术中并未涉及到如何解决上述寻呼消息 激增的问题。 发明内容
有鉴于此, 本发明的主要目的在于提供一种用户终端的寻呼方法及系 统、 用户终端、 寻呼网络, 能根据用户终端的移动状态上报相应级别的位 置区信息, 准确定位出当前用户终端的确切位置, 从而仅向用户终端当前 位置所属的网元发送寻呼消息即可。

本发明首先设置不同级别的位置区, 并设置移动状态与用户终端所上 才艮位置区级别的对应关系。 例如将现有的位置区分成更小的子位置区和 /或 微子位置区, 可以根据位置区中的话务量, 或者用户数, 或者载频来决定 划分方式。 本发明也可以按覆盖面积的大小具体设置相应的位置区级别, 如第一级为现有的位置区, 第二级位置区比第一级位置区的覆盖面积小一 些, 按此原则依次设置系统所需级别的位置区, 上述上一级的位置区与下 一级的位置区之间可以有所属关系, 也可以无所属关系。 例如, 子位置区 可以是位置区的一部分。 或者, 子位置区的覆盖区域也可以不在位置区内, 即所划分的子位置区和 /或微子位置区的划分可以与当前的位置区没有任何 关系, 子位置区和 /或微子位置区与当前的位置区是并列关系。 上述各级别 的位置区的最小单位为小区。 以下将位置区划分为位置区、 子位置区和 /或 微子位置区为例说明本发明的技术方案, 本领域技术人员应当理解, 本发 明的位置区级别数量及覆盖区域的大小可根据具体需要而设置。
本发明中, 网络侧将用户终端当前所在小区归属的位置区、 子位置区 和 /或微子位置区可通过系统消息广播给用户终端。
本发明中, 在设置位置区的级别后, 还需要根据位置区的级别设置用 户终端的位置更新策略。 具体的, 位置更新策略即确定出用户终端根据自 身的移动状态向网络侧上报当前所处的位置区和 /或子位置区和 /或微子位 置区信息。 本发明中, 将用户终端的移动状态分成高速和正常两种状态, 并分别对应于位置区和子位置区。 也可以将用户终端的移动状态分为三类, 如高速、 中速和正常, 此时, 将位置区级别设置为位置区、 子位置区及微 子位置区, 用户终端的三种移动状态高速、 中速和正常分别对应位置区、 子位置区和微子位置区。 或者, 将位置区分成位置区及子位置区, 将正常 和中速对应子位置区, 高速对应位置区, 或者正常对应子位置区, 中速和 高速对应位置区。 具体的对应关系如下列表 1至表 4所示, 但不仅限于这 些对应关系。 移动状态的分类不限于上述的两种和三种, 可以根据需要来 分成相应的级别, 位置区的分类不限于上述的两种和三种, 可以根据需要 来分成相应的级别。

表 4
本发明中, 用户终端根据自身的移动状态按上表中的位置更新策略来 上才艮相应级别的位置区。 本发明中, 上 4艮位置区信息的触发条件包括: 用 户终端开机, 或预置的位置更新周期到来, 或用户终端跨越与当前移动状 态对应级别的位置区时。 特别地, 在移动状态发生变化时, 如果是降速(如 高速变成常速), 则可以按照常速原则来处理(如跨越常速对应级别的位置 区, 如子位置区时触发上报位置区信息), 如果是升速(如常速变成高速), 则可以在用户终端第一次跨越常速对应级别的位置区 (如常速对应的子位 置区) 时上报位置区信息, 后续则按照高速原则来处理(如跨越高速对应 级别的位置区时触发上 位置区信息)。
图 3为本发明中位置区划分方式的示意图, 如图 3所示, LA代表位置 区, Sub-LA代表子位置区, Sub-Sub-LA代表微子位置区, 图 3所示的各级 别的位置区与其上一级别的位置区均为所属关系。
本发明中,用户终端移动状态是指网络的移动速度的高低,在 UMTS 中是通过统计用户终端小区重选的次数, 结合网络配置的控制参数按照 一定的规则进行比较, 然后确定用户终端的移动速度的。 也可以采用其 他的手段, 比如全球定位系统 (GPS, Global Positioning System ) , 或 者利用用户终端位置更新的频度等等来确定移动速度。 UMTS 中, 用户 终端的移动状态包括高速和正常两种。 网络侧通过系统消息将控制参数 通知用户终端, 控制参数包含 TCRmax、 NCR和 TCRmaxHyst, 其中, 1^„^为 计算小区重选次数的时间范围, NCR为小区重选的最大次数, TCRmaxHyst 为用户终端离开高速状态前的一个时间范围。 用户终端将根据这些参数 来决定自身的移动状态, 比如, 在 TCRmaJ†间范围内用户终端进行小区 重选的次数超过 NCR, 则认为进入高速状态, 如果在 TCRma ^ 范围内 用户终端进行小区重选的次数不超过 NCR, 则用户终端可以选择保持高 速状态, 或者计算在 TCRmaxHyst时间范围内用户终端不满足进入高速状态 的条件(在 TCRmaJ^ 范围内用户终端进行小区重选的次数超过 NCR ) , 则可以恢复正常状态。
以下通过具体实施例, 进一步阐明本发明技术方案的实质。
实施例一
UMTS 系统中, 确定用户终端移动状态分为高速和正常两种, 分别对 应于位置区和子位置区。 图 4为 UMTS系统中用户终端在分级位置区中移 动时的结构示意图, 如图 4所示, 图中的小区 1、 2归属于位置区 1的子位 置区 1 (以下筒称 Sub-LA-1-l ),小区 3、 4归属于位置区 1的子位置区 2 (以 下筒称 Sub-LA-1-2 ), 小区 5、 6归属于位置区 2的子位置区 1 (以下筒称 Sub-LA-2-l ) , 小区 7、 8 归属于位置区 2 的子位置区 2 (以下筒称 Sub-LA-2-2 ) , 小区 9、 10 归属于位置区 3 的子位置区 1 (以下筒称 Sub-LA-3-l )„ 小区 1、 2、 3、 4、 5归属于基站 1 , 小区 6、 7、 8、 9、 10归 属于基站 2。 用户终端当前驻留在小区 2中, 并沿着箭头方向移动, 当前移 动状态为正常。
当 UE移动到 A处, 驻留到小区 3 , 由于 UE的移动状态为正常, 位置 更新应该携带子位置区信息, 因此向网络侧发送位置更新消息, 携带 Sub-LA-1-2信息。 网络侧收到位置更新消息后, 根据 Sub-LA-1-2信息确定 当前 UE处于 Sub-LA-1-2并保存。如果网络需要与这个用户终端建立连接, 则可以将 Sub-LA-1-2携带在寻呼消息中发送给基站 1 , 基站 1收到这个寻 呼消息后, 向归属于 Sub-LA-1-2的小区 3、 4发送寻呼消息。
当 UE移动到 B处,驻留到小区 4,根据协议确定的规则和网络广播的 控制参数决定自身的移动状态变为高速。 由于 UE的移动状态为高速,位置 更新应该携带位置区信息, 因此向网络侧发送位置更新消息,携带位置区 1 信息。 网络侧收到位置更新消息后, 确定当前 UE处于位置区 1。 如果网络 需要与这个用户终端建立连接, 则可以将位置区 1携带在寻呼消息中发送 给基站 1 ,基站 1收到这个寻呼消息后, 向归属于位置区 1的小区 1、 2、 3、 4发送寻呼消息。
当 UE移动到 C处, 驻留到小区 5, 由于 UE的移动状态为高速, 位置 更新应该携带位置区信息, 因此向网络侧发送位置更新消息,携带位置区 2 信息。 网络侧收到位置更新消息后知道当前 UE处于位置区 2。 如果网络需 要与这个用户终端建立连接, 则可以将位置区 2携带在寻呼消息中发送给 基站 1和基站 2, 基站 1收到这个寻呼消息后, 向归属于位置区 2的小区 5 发送寻呼消息, 基站 2收到这个寻呼消息后, 向归属于位置区 2的小区 6、 7、 8发送寻呼消息。
