Description

多制式移动通讯网络一体化运营方法系统及装置
技术领域 本发明涉及 2G 3G/LTE/4G/以及其他无线接入技术等多制式移动通讯网络一体化运营方法。 本发明所述 2G (2rd Generation,简称为 2G)网络包括但不限于 GSM网络和 CDMA网络等第二 代移动通讯技术； 3G(yd Generation, 简称为 3G)网络包括但不限于 WCDMA网络、 TD-SCDMA 网络、 CDMA2000网洛等第三代移动通讯技术； LTE网络指 Long Term Evolution 即 3G长期技术 演进包括无线侧的 LTE和核心网侧的 EPC(Evojved Packet Core network 演进的分组核心网）； 4G 网络指第四代移动通讯网络； 其他无线接入技术则主要包括但不限于无线局域网 WLAN (采用 WIFI等标准）、无线个域网 WPAN (包括蓝牙与超宽带 UWB等）、无线城域网 WMAN(包括 WIMAX 等） 和宽带移动接入 WBMA。 本发明所述多模单待终端指， 可以支持两种或两种以上无线技术， 在某一特定时间只驻留其 中一种无线技术网络的终端。

WIFI是指 wireless fidelity无线保真
UWB 是指 ultra wideband超宽带无线技术

WBMA是指宽带移动接入 背景技术 移动通讯技术从早期的第一代（ 1G )的模拟时代， 到后来广为发展被称为第二代（2G时期的 GSM/CDMA )的数字技术时代， 现在已经进入第 3代（3G ) ,目前， 正在热门讨论、 测试的是 LTE 技术， 以后很快会进入 4G时代。 另外， 还有 WLAN、 WPAN, WMAN、 WBMA等其他无 替换页 （细则第 26条) 线接入技术.不同的时期、不同制式移动通讯技术有不同的特点，可以提供特点不同 ;6^iS£ ^K务 1G主要是提供简单的模拟电路的语音业务； 2G实现了电路域业务数字化， 除了有电路域也开始 有低速数据业务； 3G时期开始网络 IP化建设， 分组数据业务的速率也有很大提高 和 的 4G时代已经没有传统的电路域， 所有业务都将在分组数据域实现， 分组数据业务的速率也有 ί, 极大提高. WLAN等其他无线接入技术， 适合一定范围区域内提供无线接入手段; ; ： 各 *(f 技术的无线频诸都有所不同.
不管是哪一代技术， 移动通讯网络简单说都包括： 终端、 无线接入网络、 核心网络等几个部 分， 终端通过分布在不同地理区域的无线接入网络， '注册到核心网络， 就可以在不同地理区域间 自由移动的同时开展业务， 使用核心网络提供的各项业务， 实现移动通讯.
移动通讯技术包括一些关鍵技术， 如: 1.终端开机后根据不同的无线技术制式、 信号强度等 因素 > 选择需要登录的网络. 比如， 支持 GSM900M频率的终端会选择 GSM 网络登录， 支持 络登录； 2.用户从一个移动通讯网络覆盖区漫游到另一个移动通讯网络援盖区， 或一个移动通讯 网络的边界 ¾盖区信号弱于另一个移动通讯网络的边界覆盖区信号， 将发生漫游或者切换等. 比 如， 终端在通话时， 从有 3G信号覆盖的区域移动到没有 3G信号覆盖只有 2G信号覆盖的区域， 就要从 3G网络切换到 2G网络.
从世界各 S发展 3G技术的商用经验表明，一方面， 3G、 LTE等技术能提供高速率的数据业 验， 但是由于业务推广、投资成本等等各方面的原因， 3G、 ITE网络在相当长时期内只能先 实现热点地区 盖， 不可能像 2G两络那样实现广覆盖. 用户选网、 漫游、 切换等都存在一定问 题，影响用户业^ 验； 另一方面， 2G网络经过 10几年的大 商用建设， 盖已经非常全面， 网络质量也比较理想， 是提供一般 CS业务和低速 PS业务的最佳手段， 同时， 积累投资的成本 也非常高了， 不可能一下消亡. WLAN等其他无线接入技术虽然能广域无线网络弥补楼宇覆盖 不足等劣势， 但也无法实现广域覆盖.
这种情况下， 所有的运营商都面临：
1.如何向用户提供高速率数据 Jk务的同时， 向用户提^ ^人满意的 CS业务；
2.如何保护以往巨大的既有投资， 使它们不是迅速成为运营商的沉没成本， 而是能持续不断 的发挥其作用；
3.如何使已有的 2G网络、 3G网络， 在建的 LTE网络， 以后的 4G网络以及其他无线接入技 术等平衡
4.室内、 楼宇. 隧道等特殊场合， 无线信号衰落严重， WLAN等技术虽然可以很妤实现这些 场所的覆盖， 但无法和广域网互动， 形成一个一体化网络.
这是接在通讯业界所有人面前的普遍问題.
现有技术存在的问题是：
无论是 2G/3G/LTE/4G哪种技术的网络，现在彼此之间都是独立运行，无法感知其他网络的运 营情况， 无法彼此秉顾, 互相发挥优势， 形成补充关系， 甚至某种程度上还有点竟争关系， 这对 同时部署多种制式网络的运营商来说是非常不利的.
比如， 3G网络 PS域虽然能提供较 2G网络 PS域高的速率， 但是， 运营商在发展 3G网络时， 一般只能先实现热点地区 3G网络覆盖，网络覆盖空洞很多、很广， 3G网络边缘地区信号质量差、 不稳定， 和 2G网络的乒乓漫游、 切换频繁， 用户的选网、 驻留策略等都是运营商非常难以很好 ^ 解决的问题.
而且， 3G/2G都能提供 CS业务， 两者虽然都是同一个运营商的网络， 却是有点竟爭^ ¾¾'. 至在 2G网络资源不够， 3G网络资源剩余的情况下， 也无法 3G也补充 2G网络.
3G网络 PS域和 WLA 等其他无线接入技术，都能提供髙速率、大带宽的分组数据 « ¾Ki s 即使它们都是同一个运营商的网络， 也是竟争关系， 要么用户从 3G网络 PS域接入， 要么从其 他无线接入技术， 即使某个网络资源紧张， 另一个网络空闲， 也不能从空闲网^ έ入.
乒乓漫游、 切换带来大量的无效信令流量、 降低网络效率， 增加网络维护难度， 降低了用户 的使用满意度. 资源紧张、 信号质量差、 不穗定， 用户满意度降低， 运营商吸引用户难度加大， 恶性循环.
尤其是对于中国、 加拿大、 印度、 美国这类地域较广的国家， 如何， 建立一个高质量的无线 通讯网络， 向用户提供高速率的 PS业务的同时， 减少不同网络网间漫游、 切换， 优化用户的选 网、 驻留策略， 给用户满意的语音服务， 世界各国的运营商都遇到了很多的问題， 没有满意的解 决方案.
还有， 一种新技术网络在开始建设后的相当长一段时期内， 用户数的增长有限， 而网络设备 的设计资源都是大容量的， 造成网络资源大量空闲， 另一方面， 老技术网络经过多年的发展， 用 户数量增长迅猛， 并且由于成本下降的优势， 用户还在不断增加， 老技术网络资源越来越紧张. 如何平衡利用各个网络的资源， 使投资效益最大化也是一个重大问题.
如杲， 使终端同时驻留多个模式的网络， 终端到底应该选择哪个网络发生业务， 变成一个复 杂问题， 对终端的电池待机能力也提出了极大的挑战. 发明内容
本发明所要解决的技术问题是在 2G 3G LTE/4G以及其他无线接入技术等多制式移动通讯网 络建设过程中， 如何最大限度利用各种网络的优势，使各种技术下的网络成为一体化运营的统一 网络. 比如， 在最大限度利用 3G/LTE/4G 网络大带宽、 髙速率、 资源充足的优势同时， 充分利 用 2/3G网络广覆盖、 语音盾量好的优势， 综合平衡利用 2 3/LTE 4G网络各个网络资源 > 使运营 商的 2 3/LTE/4G网络自动统一成一张完整的网络， 发挥最大的社会和经济效益. 在某种网络资 源紧张时， 能够通知其他资源富余的网络， 帮助分担业务负荷， 使各种网络都成为健壮运行的高 质量网络。

3. 目标网络接受用户终端注册请求后， 发起联合注册流程（比如联合位置更新流程）， 让终 端也注册到目标网络各个域，或者通过特定流程把终端从初始驻留网络各个域注销； 终端成功注 册到目标网络后， 初始驻留网络释放相关资源；
4. 当用户在目标网络的业务完 A ^或者当用户在目标网络发生特定业务时（比如在 3G网 络发生 CS业务， 也可以先在目标网络完成此次 CS业务， 然后）， 目标网络向初始驻留网络发送
-迁移通知消息， 把该终端迁移回初始驻留网络， 消息中携带自己新的迁移权重比； 初始驻留网络 收到该迁移通知消息后， 保存目.标网络网元新的迁移权重比， 并向目标网络发送迁移接受消息， 消息中携带自己的迁移权重比； 初始驻留网络网元发送接受迁移消息后， 触发起终端! ¾式强制 注册机制， 向用户终端发送特定消息， 让终端重新触发注册流程（比如路由更新流程）向初始驻 留网络注册； 初始驻留网络接受用户路由更新请求后， 发起联合注册 ϊ¾程（比如联合位置更新流 程）， 让终端也注册回到初始驻留网络各个域；
以上是由于发生业务， 引起的网络迁移. 除了这种方式， 还可以为了实现网络资源均衡使 用， 由驻留网络向目标网络发起通知消息， 实现迁移， 包括以下步壤：
1. 在网络部署时， 配置给各个网元的迁移权重比， 每个网元保存记录自己的迁移权重比和 其他目标网络网元的迁移权重比，要迁移时根据保存的目标网络网元权重比选择目标迁移网络 W 元； 在有初始驻留网络（比如 2G网络）和目标网络（比如 3G/LTE/4G ) 网络共覆盖的区域 当初始驻留网络资源紧张时， 迁移发起网络网元向有适当迁移权重比的目标网络网元（比如 2q MSC向 3G MSC Server, 或者 2G SGSN向 3G SGSN,或者 3G SGSN向 LTE MME等等）发出迁 移通知消息， 消息中携带本网络迁移权重比；
2. 目标网络网元收到迁移通知消息后， 根据自身资源负荷情况决定是否接受此用户迁移， 如果不接受， 直接向初始驻留网络网元返回迁移拒绝消息， 消息携带自己最新的迁移权重比， 初 始驻留网络网元收到目标网络的迁移拒绝消息后， 保存目标网络网元新的迁移权重比， 重新根据 各个网元迁移权重比选择新的迁移目标， 重新触发新的迁移流程； 如果接受， 保存初始驻留网络 网元的迁移权重比， 根据需要调整自己的迁移权重比， 并向驻留网络网元逸回迁移接受消息， 消 息携带自己新的迁移权重比； 并鍅发起终端隐式注册机制， 向用户终端发送特定消息， 让终端重 新通过目标网络新的无线接入技术触发注册流程（比如路由更新流程）向目标网络注册； 3. 目标网络接受用户终端注册请求后， 发起联合注册流程 (比如联合位置更新流程 终端也注册到目标网络各个域,或者通过特定流程把终端从初始驻留网络各个域注销； 终端成功 注册到目标网络后， 初始驻留网络释放相关资源；

目标网络接受用户终端注册请求后， 发起联合注册流程 （比如联合位置更新流程）， 让终端也注册 到目标网络各个域，或者通过特定流程把终端从初始驻留网络各个域注销； 终端成功注册到目标网络 后. 初始驻留网络释放相关资源；
以上是由于发生业务， 引起的网络迁移。 除了这种方式， 还可以为了实现网络资源均衡使用， 由 驻留网络或目标网络发起通知消息， 实现迁移， 包括以下步骤： 在网络部署时， 配置给各个网元的迁 移权重比， 每个网元保存记录自己的迁移权重比和其他目标网络网元的迁移权重比， 要迁移时根据保 存的目标网络网元权重比选择目标迁移网络网元； 在有初始驻留网络 （比如 2G 网络） 和目标网络 (比如 3G/LTE/4G ) 网络共覆盖的区域， 当初始驻留网络资源紧张时， 迁移发起网络网元向有适当 迁移权重比的目标网络网元 （比如 2G MSC向 3G MSC Server, 或者 2G SGSN向 3G SGSN，或者 3G SGSN向 LTE MME等等） 发出迁移通知消息， 消息中携带本网络迁移权重比； 目标网络网元收到迁 移通知消息后， 根据自身资源负荷情况决定是否接受此用户迁移， 如果不接受， 直接向初始驻留网络 网元返回迁移拒绝消息， 消息携带自己最新的迁移权重比， 初始驻留网络网元收到目标网络的迁移拒 绝消息后， 保存目标网络网元新的迁移权重比， 重新根据各个网元迁移权重比选择新的迁移目标， 重 新触发新的迁移流程； 如果接受， 保存初始驻留网络网元的迁移权重比， 根据需要调整自己的迁移权 重比， 并向驻留网络网元返回迁移接受消息， 消息携带自己新的迁移权重比； 并触发起终端隐式注册 机制， 向用户终端发送特定消息， 让终端重新通过目标网络新的无线接入技术触发注册流程 （比如路 由更新流程） 向目标网络注册； 目标网络接受用户终端注册请求后， 发起联合注册流程 （比如联合位 置更新流程）， 让终端也注册到目标网络各个域,或者通过特定流程把终端从初始驻留网络各个域注销； 终端成功注册到目标网络后， 初始驻留网络释放相关资源； 根据权利要求 1所述的方法， 其特征在于： 权 利 要 求 书
