Description

一种基于 LTE系统的信息推送方法和系统 本申请要求于 2010年 12月 24 日提交中国专利局, 申请号为 201010621143.6, 发明名称为 "一种基于 LTE系统的信息推送方法和 系统"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
本发明涉及通信技术领域, 尤其涉及一种基于 LTE 系统的信息 推送方法和系统。 背景技术
1 )短信推送机制
在 2G (第二代移动通讯技术) 系统中, 短信推送系统的工作原 理是当终端在 MSC ( Mobile Switching Center, 移动交换中心)之间 切换时, 需要与交换机交换数据信息, 当终端进行跨省市或在不同交 换机之间切换时, 可通过 HSTP ( High Signalling Transfer Point , 高级 信令点)和 LSTP ( Low Signalling Transfer Point, 低级信令点)接口 得到其位置信息的变动, 从而对进入一定范围的终端推送短信。
在短信业务迅速发展的同时,垃圾短信的存在成为制约其大幅增 长的瓶颈。由于交换机的覆盖范围较大,通常为一个省份或一个地区, 无选择性地向用户推送短信必然导致用户体验的下降,因此上述短信 推送系统只限于提升运营商服务质量的一般欢迎类信息。
为了更有针对性地向用户推送短信,现有技术中提出了一种小区 短信系统, 如图 1所示的小区短信系统示意图, 通过监测 BTS ( Base Transceiver Station, 基站 发信台)、 BSC ( Base Station Controller, 基站控制器)、 MSC、 LSTP, HLR ( Home Location Register, 归属位 置寄存器)之间的接口信息, 以统计终端用户进出特定小区的信息, 以及终端 IMSI ( International Mobile Subscriber Identity, 国际移动用 户标识)与 MSISDN( Mobile Subscriber ISDN Number,移动用户 ISDN 号; ISDN, Integrated Service Digital Network, 综合业务数字网)之 间的对应关系, 该对应关系用于推送短信。
基于图 1所示的小区短信系统, 相应的工作步骤包括: (1 )信令 采集部分采集 Abis接口、 A接口、 C接口及 MSC到 LSTP接口的数 据;数据处理部分通过解析上述数据得到终端在特定位置的信息以及 终端进出特定区域的信息。 ( 2 )对上述数据进行过滤分类处理后得到 系统关心的数据, 并存入数据库。 (3 )对数据库内存储的数据进行分 类、 筛选, 并存入用户群数据库。 (4 )由短信发布部分发送短信息到 用户群。 通过上述步骤, 该小区短信发布系统可对特定客户群(如旅 客、 购物者、 住宿及就餐人员 )提供富有个性化的短信推送服务。
2 ) LTE ( Long Term Evolution, 长期演进 ) 系统及短信发送机制 在 LTE 系统中, 无线接入侧节点为单个节点 eNB ( evolved NodeB ), 核心网节点完成控制面与用户面的分离, 控制面节点为 MME ( Mobility Management Entity , 移动性管理实体), 用户面节点 为 SGW ( Serving Gateway, 服务网关 )与 PGW ( PDN GW, PDN网 关; PDN, Packet Data Network, 分组数据网络)。 其中, MME负责 所有与终端移动性管理与会话管理的相关信令(如附着、 位置更新、 切换等); MME与 eNB之间的接口为 S1-MME接口,其上采用 SI AP ( S 1 Application Protocol , S 1接口应用协议)。
在移动通信系统中,位置更新技术使得成功附着的终端在移动时 仍能在网络中保持注册, 当终端移出注册位置区时即发起位置更新过 程。 在 LTE系统中位置区单元为 TA ( Tracking Area, 跟踪区)。 为了 适应以不同速率运动的终端,并保持寻呼量与终端位置更新频率之间 的平衡, 制定了跟踪区列表(TA List )技术, 即网络为终端分配一个 包含一个或多个 TA的 TA List, 当终端移出该 TA List时才发起位置 更新过程。 其中, TA List中包含的 TA及其数量由 MME根据一定策 略决定。
在 2G、 3G (第三代移动通讯技术 )系统中,短信通过 CS ( Circuit Switch, 电路交换) 方式发送。 而由于 LTE系统是一个全 IP系统, 因此其短信发送方式包括: a、 PS ( Packet Switch, 分组交换)短信, 这种方式下短信业务与其它 LTE业务一样均采用 PS方式发送; b、 CS短信, 这种方式下可通过 CS回退技术, 将 CS短信封装在 LTE 信令中发送, 或将终端切换到 2G/3G网络再接收 CS短信。
在实现本发明的过程中,发明人发现现有技术中至少存在以下问 题:
由于网络架构、接口信令均发生了根本性的改变, 现有的漫游短 信及小区短信机制不能应用于 LTE系统; 此外, 由于 LTE系统路由 区划分和位置更新机制的改变, 以及短信发送方式的不同, 现有机制 不能 4艮好地实现信息推送的功能。 发明内容
本发明实施例提供一种基于 LTE 系统的信息推送方法和系统, 以在 LTE系统中向用户推送信息。
为了达到上述目的, 本发明实施例提供一种基于 LTE 系统的信 息推送方法, 包括:
根据接入网设备与移动性管理实体之间交互的信息获取终端位 置信息, 并获取终端标识信息;
根据所述终端位置信息和所述终端标识信息将待推送信息发送 给终端。 本发明实施例提供一种基于 LTE系统的信息推送系统, 包括: 数据搜集分析实体,用于根据接入网设备与移动性管理实体之间 交互的信息获取终端位置信息, 并获取终端标识信息; 并根据所述终 端位置信息向信息推送实体发送通知消息,该通知消息中携带所述终 端标识信息;
信息推送实体, 用于当接收到通知消息时, 根据所述终端标识信 息触发信息发送平台将待推送信息发送给终端。 与现有技术相比, 本发明至少具有以下优点:
结合 LTE 系统移动性管理机制, 使得系统可根据应用需求锁定 不同的用户群, 并根据其行为特征向用户推送信息, 避免了无关短信 对用户的影响以及对系统资源的浪费。

具体实施方式
下面结合附图和实施例,对本发明的具体实施方式作进一步详细 描述:
现有移动通信系统中,基于信令监测的漫游短信和小区短信机制 已得到广泛应用; 然而在 LTE系统中, 目前还没有机制能够有效地、 有选择地向用户推送信息, 同时避免无关短信对用户体验的影响。 针 对上述问题, 本发明实施例提供一种基于 LTE 系统的信息推送方法 和系统, 以在 LTE系统中向用户推送信息。
下面将结合本发明中的附图, 对本发明中的技术方案进行清楚、 完整地描述, 显然, 所描述的实施例仅仅是本发明的一部分实施例, 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 在没有做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。 本发明实施例一提供一种基于 LTE 系统的信息推送方法, 该方 法应用于 LTE系统中, 如图 2所示的组网架构示意图。 在 LTE系统 中, 至少包括无线接入侧节点 eNB , 控制面节点 MME , 用户面节点 SGW、 PGW, HSS ( Home Subscriber Server, 归属用户服务器)和信 息发送平台。 其中, eNB 与网络侧之间的接口为 S1 接口, eNB 与 MME之间的接口为 S1-MME接口, eNB与 SGW之间的接口为 S1-U 接口; MME与 SGW之间的接口为 S11接口; SGW与 PGW之间的 接口为 S5接口; PGW与信息发送平台之间的接口基于 SGi接口; MME与 HSS之间的接口为 S6a接口。 在上述 LTE系统中, 本发明 实施例中还设置有数据搜集分析实体和信息推送实体,二者构成了本 发明实施例提供的信息推送系统。 其中, 二者可以部署在同一个设备 上,也可以部署在不同设备上;二者可以部署在现有的网元上(例如, 将数据搜集分析实体部署在 MME上、将信息推送实体部署在信息发 送平台上), 也可以单独实现。 为了方便描述, 本发明实施例中以数 据搜集分析实体和信息推送实体分别单独实现为例进行说明。
基于上述情况, 如图 3 所示, 本发明实施例一提供的基于 LTE 系统的信息推送方法包括以下步骤:
步骤 301 , 数据搜集分析实体获取终端位置信息, 并获取终端标 识信息。 其中, 数据搜集分析实体可根据接入网设备 eNB 与 MME 之间交互的信息获取终端位置信息。 具体的, 数据搜集分析实体通过 监测 eNB与 MME之间的 S1接口信息(即 S1-MME接口信息;), 即 可根据监测结果获取终端位置信息。
本发明实施例中,该终端位置信息包括但不限于以下信息的一种 或几种: 终端进入特定区域的信息; 终端位于特定区域的信息; 终端 离开特定区域的信息。 其中, 该特定区域可以是一个或多个 TA ( Tracking Area, 跟踪区)。 在 eNB与 MME之间交互信息的过程中, 数据搜集分析实体可通过 eNB与 MME交互的位置更新信息或切换 信息获取终端进入特定区域的信息; 可通过 eNB与 MME交互的位 置更新信息或服务请求信息或附着过程信息获取终端位于特定区域 的信息; 可通过 eNB与 MME交互的位置更新信息或切换信息获取 终端离开特定区域的信息。
实际应用中, 为了监测 eNB与 MME之间的 S1接口信息, 数据 搜集分析实体输入端与 S1-MME接口可通过高阻跨接或阻抗匹配方 式连接, 使得不影响现有网络的正常运行, 且数据搜集分析实体可对 eNB 与 MME之间的交互过程进行监测, 从而可以监测到 eNB 与 MME交互的位置更新过程、 切换过程、服务请求过程、 附着过程等, 继而可获知终端进入特定区域的信息、 终端位于特定区域的信息、 终 端离开特定区域的信息。 另外, 如果数据搜集分析实体部署在 MME 上时, 则数据搜集分析实体可直接监测 eNB与 MME交互的过程, 并获知自身需要的信息。 另外, 还可以由 MME获取终端进入特定区 域的信息、 终端位于特定区域的信息、 终端离开特定区域的信息, 并 将相应信息通知给数据搜集分析实体。
本发明实施例中, 在使用 CS的发送方式向终端发送待推送信息 时, 数据搜集分析实体可根据 MME与 HSS之间交互的信息获取终 端标识信息 (或者, 数据搜集分析实体可根据 MME与 HSS之间交 互的信息以及接入网设备与移动性管理实体之间交互的信息获取终 端标识信息)。 具体的, 数据搜集分析实体可通过监测 MME与 HSS 之间的 S6a接口信息(或者监测 S6a接口信息和 S1接口信息 ), 即可 根据监测结果获取终端标识信息。
实际应用中, 当采用 CS方式向终端发送待推送信息时, 终端标 识信息包括 MSISDN, 因此, 根据从 S6a接口上获得的 IMSI 与 MSISDN之间的对应关系, 即可以将待推送信息发送给对应的终端。
具体的, 在根据 MME与 HSS之间交互的信息获取终端标识信 息的过程中, 数据搜集分析实体可建立终端相关临时标识与终端 IMSI之间的对应关系、 以及终端 IMSI与 MSISDN之间的对应关系, 从而可确定终端标识信息。
另外, 在使用 PS的发送方式向终端发送待推送信息时, 数据搜 集分析实体可根据服务网关与分组数据网络网关之间交互的信息、以 及分组数据网络网关与信息发送平台之间交互的信息获取终端标识 信息。 具体的, 数据搜集分析实体通过监测服务网关与分组数据网络 网关之间的 S5接口信息、 以及分组数据网络网关与信息发送平台之 间的 SGi接口信息, 并根据监测结果获取终端标识信息。
实际应用中, 当采用 PS方式向终端发送待推送信息时, 终端标 识信息包括用户在 PS域的标识 (如 SIP ( Session Initiation Protocol, 会话初始协议)URI( Uniform Resource Identifier,统一资源标识)等)。 具体的, 为了获得终端标识信息, 还可以根据终端定制业务的终端业 务信息与终端标识信息的对应关系进行获取。而为了获取终端业务信 息, 数据搜集分析实体可根据 SGW与 PGW之间交互的信息以及 PGW与信息发送平台之间交互的信息进行获取。 因此, 数据搜集分 析实体通过监测 SGW与 PGW之间的 S5接口信息、 以及 PGW与信 息发送平台之间的 SGi接口信息,即可根据监测结果获取终端标识信 实际应用中, 为了监测 ΜΜΕ与 HSS之间的 S6a接口信息, 数 据搜集分析实体输入端与 S6a接口可通过高阻跨接或阻抗匹配方式 连接, 使得不影响现有网络的正常运行, 且数据搜集分析实体可对 MME与 HSS之间的交互过程进行监测,从而可以获知终端标识信息。 另外, 为了监测 SGW与 PGW之间的 S5接口信息、 PGW与信息发 送平台之间的 SGi接口信息, 数据搜集分析实体输入端与 S5接口可 通过高阻跨接或阻抗匹配方式连接, 数据搜集分析实体输入端与 SGi 接口可通过高阻跨接或阻抗匹配方式连接,使得不影响现有网络的正 常运行, 且数据搜集分析实体可对 SGW与 PGW、 PGW与信息发送 平台之间的交互过程进行监测, 从而可以获知终端业务信息, 继而获 知终端标识信息。 步骤 302, 数据搜集分析实体根据终端位置信息向信息推送实体 发送携带终端标识信息的通知消息,由信息推送实体根据该终端标识 信息触发信息发送平台将待推送信息发送给终端。 其中, 数据搜集分 析实体可根据终端位置信息统计终端数据,并根据终端数据确定待推 送终端, 在监测到待推送终端的指定行为 (如离开特定区域等)后, 向信息推送实体发送通知消息, 该通知消息中携带终端标识信息; 当 接收到该通知消息后,信息推送实体根据该终端标识信息触发信息发 送平台将待推送信息发送给终端。
本发明实施例中,该终端数据包括但不限于以下信息的一种或几 种: 终端在特定区域内停留的时间; 终端进出特定区域的频率; 终端 在特定区域中发起业务的频率和时间; 终端访问特定区域的时间段; 终端以连接态停留在特定区域内的时间。 具体的, 根据上述终端进入 特定区域的信息、 终端位于特定区域的信息、 终端离开特定区域的信 息, 该数据搜集分析实体即可以统计出终端数据。
本发明实施例中, 当确定了终端数据 (各个终端对应自身的终端 数据, 所有的终端可统计出用户行为数据库)后, 可根据一定准则从 该用户行为数据库中筛选出特定的终端, 并根据实时监测数据, 当感 知到特定终端进入、位于或离开特定区域时, 触发信息发送平台推送 待推送信息。
另外, 根据终端标识信息将待推送信息发送给终端时, 在数据搜 集分析实体的通知下,信息推送实体通知信息发送平台根据终端标识 信息将待推送信息发送给终端, 之后, 信息发送平台根据终端标识信 息将待推送信息发送给终端。 其中, 该待推送信息的发送方式包括但 不限于基于 CS的发送方式(如 CS短信)、 或者基于 PS的发送方式 (如 PS短信)、 或者其它应用相关信息形式。
综上所述, 本发明实施例中, 结合 LTE 系统移动性管理机制, 使得系统可根据应用需求锁定不同的用户群,并根据其行为特征向用 户推送信息, 避免了无关短信对用户的影响以及对系统资源的浪费。 而且本发明实施例提供了灵活的信息发送形式, 适合 LTE 时代丰富 的应用需求。 为了更加清楚的阐述本发明实施例提供的技术方案,以下结合具 体的应用场景对本发明实施例进行详细说明。
本发明实施例二提供一种基于 LTE 系统的信息推送方法, 本实 施例针对感知终端位置信息的过程进行详细说明。 本实施例中, 某热 点区域属于跟踪区 TA, 其 3艮踪区标识为 TAI_1。 该 TA由 eNB_l , eNB_2, eNB_3三个基站覆盖, 且均由同一个 MME服务。 数据搜集 分析实体监测 eNB_l , eNB_2和 eNB_3与 MME之间的接口, 并结 合 MME存储的终端上下文可获得终端进出该特定区域的信息, 该信 息如下:
( 1 ) 当终端从其它基站切换到 eNB_l/2/3 时, 数据搜集分析实 体可从 S1-MME接口上的切换信令获得终端的源小区、 目标小区, 以及目标小区所属的 TAI, 即可以获知终端已进入特定区域。 其中, 该切换信令 (以切换请求 HO Required为例 ) 内容如表 1所示: 表 1
Figure imgf000011_0001
(目标 ID ) 其中, MME UE S1AP ID唯一确定了 Sl-MME接口上的一个 per UE连接,结合 MME中存储的以终端 IMSI为唯一关键字的终端上下 文, 以及 S6a接口信息, 可以获得 MME UE S 1 AP ID与 IMSI之间的 关联信息, 并获得当前终端的 IMSI信息。 Target ID是切换目标侧标 识, 在本实施例所述的 intra-LTE切换中为目标 eNB标识 Global eNB ID及其所属 TAI。 通过 Target ID可以获知终端已进入以 TAI=TAI_1 为标识的特定区域。
( 2 )类似的, 当终端从 eNB_l/2/3切换到其它小区时, 可通过 ( 1 )所述方法获知终端离开特定区域。
( 3 ) 当空闲态终端进入该 TA并发起位置更新过程时, 通过解 析 Sl-MME接口相关信令,可获知终端进入该特定区域。其中, S1AP 信令(以初始 UE消息: Initial UE Message为例 )的内容如表 2所示: 表 2
Figure imgf000012_0001
其中, TAI和 E-UTRAN CGI表明当前终端所在的跟踪区和小区, 通过解析该 S1AP消息可获知终端进入特定区域。
( 4 )类似的, 当空闲态终端移出该 TA并在其它 TA内发起位置 更新过程时, 可以通过(3 )所述方法获知终端离开该特定区域。
( 5 ) 当空闲态终端在特定区域中发起其它非接入层过程(如服 务请求) 时, 同理 S1-MME接口上仍能监测到终端相关信令, 因此 数据搜集分析实体可获知终端位于特定区域中。 本发明实施例三提供一种基于 LTE 系统的信息推送方法, 本实 施例针对数据统计的过程进行详细说明。 本实施例中, 某热点区域属 于跟踪区 TA,其跟踪区标识为 TAI_1。该 TA由 eNB_l , eNB_2, eNB_3 三个基站覆盖, 且均由同一个 MME服务。 数据搜集分析实体监测 MME与 HSS之间的 S6a接口可获得终端 IMSI、 MSISDN等信息。 数据搜集分析实体基于 eNB_l/2/3 与 MME之间接口的实时监测数 据, 可以至少统计出以下信息的一种或几种: 终端在特定区域 TA中 停留的时间; 终端进出特定区域 TA的频率; 终端在特定区域 TA中 发起业务的频率和时间; 终端访问特定区域 TA的时间段; 终端以连 接态停留在特定区域内的时间。 进一步的, 数据搜集分析实体根据一 定的过滤规则对用户进行分类, 并筛选出需要的用户。 可选地, 数据 搜集分析实体通过监测 SGW与 PGW之间的 S5接口, 以及 PGW与 信息发送平台之间的 SGi接口, 可以获得终端的业务信息, 如终端的 IP地址、 终端在信息发送平台中的标识等。 本发明实施例四提供一种基于 LTE 系统的信息推送方法, 本实 施例针对信息推送的过程进行详细说明。基于本发明实施例三, 数据 搜集分析实体已经筛选出需要推送信息(待推送信息)的用户, 设其 中一个用户的 IMSI为 IMSI_1。数据搜集分析实体根据实时监测数据, 当监测到用户终端行为符合特定行为特征如进入、萬开或位于特定区 域时, 触发信息发送平台向用户终端发送信息, 如图 4所示的信息发 送流程示意图, 包括: 1、 数据搜集分析实体监测终端行为。
2、 当监测到终端符合特定行为特征时, 数据搜集分析实体向信 息推送实体发出通知。
3、 信息推送实体触发信息发送平台。
4、 信息发送平台根据现有机制发送信息。
在上述过程中, 特定行为特征可根据应用场景需要设定, 在设定 后根据实施例所述, 数据搜集分析实体可获知终端进入、 离开以及位 于特定区域的信息, 并根据实际需求推送信息。 基于与上述方法同样的发明构思,本发明实施例五中还提供了一 种基于 LTE系统的信息推送系统, 该系统包括: 数据搜集分析实体, 用于根据接入网设备与移动性管理实体之间交互的信息获取终端位 置信息, 并获取终端标识信息; 并根据所述终端位置信息向信息推送 实体发送通知消息, 该通知消息中携带所述终端标识信息; 信息推送 实体, 用于当接收到通知消息时, 根据所述终端标识信息触发信息发 送平台将待推送信息发送给终端。
