Description

一种机器类通信事件的上报方法及相应装置
技术领域
本发明涉及通信领域, 尤其涉及一种机器类通信事件的上报方法及相应 装置。
背景技术
随着移动网络服务和自动化控制技术的发展, 出现了一种机器类通信 ( Machine Type Communication, 简称为 MTC )方式, 在该通信方式中, 通 信的双方均为机器设备。
在 MTC通信中, 通信行为是自动化控制的, 即: 通信的发起、 终止及 通信过程中的一些准入和限制的控制均是自动化的行为。 这种行为依赖于 MTC通信中对机器 (即 MTC通信中的终端)行为的约束和控制。 MTC通信 中的终端的行为受业务签约数据的约束, 网络根据业务签约数据对 MTC通 信中的终端进行管理。
机器类通信中最典型的通信方式为终端和应用服务器之间的通信, 该终 端被称为 MTC终端 (MTC User Equipment, 简称为 MTC UE ) , 应用服务 器被称为 MTC服务器 ( MTC Server ) 。
在 2G ( 2nd Generation, 第二代移动通信技术) /3G ( 3rdGeneration, 第 三代移动通信技术) /LTE ( Long Term Evolution, 长期演进)接入下, MTC 通信主要以分组(Packet Service, 简称为 PS ) 网络作为底层承载网络, 实现 MTC终端和 MTC服务器之间的业务层通信。具体地, MTC通信实体可以通 过演进的通用移动通信系统陆地无线接入网 (Evolved Universal Terrestrial Radio Access Network, 简称为 E-UTRAN )接入到演进的分组系统( Evolved Packet System,简称为 EPS )网络,也可以通过 GSM( Global System for Mobile communications , 全球移动通信系统 ) /EDGE ( Enhanced Data Rate for GSM Evolution, 增强型数据速率 GSM演进)无线接入网络(GSM/EDGE Radio Access Network, 简称为 GERAN ) /UTRAN 网络接入到通用无线分组业务 ( General Packet Radio Service, 简称为 GPRS ) 。 图 1是 MTC通信实体接入到 EPS的架构示意图。如图 1所示, MTC Server 可以充当应用功能实体( Application Function , 简称为 AF )的角色, 通过 Rx 接口与策略和计费规则功能实体 ( Policy and Charging Rules Function, 简称 为 PCRF )连接,以实现对承载的控制。此夕卜, MTC Server可以充当 SIP( Session Initiation Protocol, 会话初始协议) AS ( Application Server ) 的角色, 通过 Sh接口和归属用户服务器(Home Subscriber Server, 简称为 HSS )连接, 以 存取应用服务数据。
如图 1所示, 一般情况下, MTC UE通过 E-UTRAN中的 eNodeB (演进 节点 B )接入到 EPS网络中。 在被分配 IP地址后 , MTC UE与 MTC Server 之间可以建立起 IP通道,从而实现与 MTC Server之间的上层业务通信。 MTC UE与 MTC Server之间所建立的 IP通道为一条逻辑上的 IP通道, 其物理路 径经过: eNodeB、 服务网关 (Serving Gateway, 简称为 S-GW或 SGW ) 、 分组数据网络网关( Packet Data Network Gateway, 简称为 PDN GW、 P-GW 或 PGW ) 。
在实际应用中, MTC Server需要监控 MTC UE的运行状态, 及时动态 地获知 MTC UE当前的状态,并在 MTC UE当前的状态发生变化时及时获知。 其中, MTC UE的状态变化可能包括: MTC UE从网络去附着、 MTC UE进 入非连接状态、 MTC UE释放了无线连接、 MTC UE的当前位置发生了变化 等。 这些 MTC UE的状态的变化, 可以称之为一个 MTC事件。 通常可以在 归属位置寄存器( Home Location Register, 简称为 HLR )或 HSS的 MTC业 务签约数据中定义需要监控的 MTC事件, 并且通过 MTC UE的附着到网络 的流程由 HLR 或 HSS 下发给服务通用分组无线业务支撑节点 (Serving General packet radio service Support Node, 简称为 SGSN )或 MME ( Mobility Management Entity, 移动管理实体) 。
而对于 MTC事件的检测, 则通常需要核心网的网络实体来进行。 如在
EPS网络中, 负责 MTC事件的检测实体(以下简称 MTC事件检测实体)包 括:
SGSN或 MME: 可以检测大部分的移动性管理事件, 比如: 附着、 去附 着; GGSN ( Gateway GPRS Support Node, 网关 GPRS支持节点)、 SGW或 PGW: 可以检测和承载相关的事件, 比如: 承载创建、 释放;
PCRF:可以检测和承载相关的事件,比如:承载创建、释放、 RAT ( Radio Access Technology, 无线接入技术)切换等。
当上述 MTC事件检测实体检测到 MTC事件后, 需要由 MTC事件上报 实体报告给 MTC Server。MTC事件上报实体可以是 MTC事件检测实体本身, 也可以是其他相关实体,如:在 MTC事件检测实体是 MME的情况下, MTC 事件上报实体可以是 PGW。
在实际应用中, 存在一个 MTC UE的 MTC事件同时被多个 MTC服务 所订阅的情况, 即存在多个 MTC服务器希望获得相同的 MTC事件的情况, 或者不同的 MTC服务希望获得同一个 UE的不同的 MTC事件的情况。 在现 有技术下, 需要 MTC事件检测实体和 MTC事件上报实体针对不同的 MTC 服务器对 MTC事件的订阅, 分别地将 MTC事件通知对应的 MTC服务器。
相关技术对于多方订阅 MTC事件的情形考虑的还不多。 如果按照相关 技术, 需要在 HSS中签约多方 AS对特定 MTC事件的订阅信息, 并下载到 SGSN或 MME中; 当 SGSN或 MME检测到相应的 MTC事件时, 需要将 MTC事件同时发送给多方 AS。
以 E-UTRAN接入为例 , 以 MME作为 MTC事件检测实体和 MTC事件 上报实体, 将 MTC事件报告给多个 MTC应用服务器的流程, 如图 2所示, 包括:
201 : MTC UE附着成功后 , HSS向 MME下载该 MTE UE的签约数据; 其中, 该签约数据中包括 MTC业务签约数据。 特别地, 在 MTC业务签约数 据包括多方 AS对 MTC事件的订阅信息;
202: 当 MME检测到 MTC事件时, 执行步骤 203;
203: MME根据多方 AS对 MTC事件的订阅信息, 将该 MTC事件报告 给多方 AS, 如 MTC AS1、 MTC AS2等。
上述方法可以实现将 MTC事件通知到多个不同的 MTC服务器的目的, 但是该方法对于网络而言增加了复杂性、 冗余性, 并且网络功能的划分也不 够清晰。 比如: 订阅 MTC事件、 将 MTC事件报告给多个签约该 MTC事件 的 MTC服务器, 属于应用层的范畴, 而按照现有技术, 需要 SGSN或 MME 到应用层进行处理, 使得逻辑功能混乱, 并且在 SGSN、 MME上增加了多方 分发的复杂性。 如果其中一个 MTC事件报告失败, SGSN、 MME还需要緩 存该 MTC事件并进行重发。 这些无疑增加了 SGSN、 MME的处理负担, 当 MTC终端大量应用到网络后, 更容易导致 SGSN、 MME过负荷。 发明内容

除上述说明外, 所述 MTC终端的 MTC业务签约数据中还可包括: 订阅
MTC事件的应用服务器用来标识所述 MTC终端的外部标识信息。
下面以三个应用示例进行进一步说明。
应用示例一
在本应用示例中 , MTC事件的检测和上报均由 MME执行。如图 4所示, 将 MTC事件上报给多方 MTC服务器的方法, 包括:
S401 , MTC UE请求附着到网络中; 在该 MTC UE附着成功后, 网络根 据 MTC UE的签约数据, 启动 MTC事件监控和检测功能。
在附着过程中, MME向 HSS发送位置更新报告, HSS 向 MME下载 MTC UE的签约数据;其中,在 HSS向 MME下载的 MTC UE的签约数据中, 包括 MTC业务签约数据。 特别地, MTC业务签约数据包括以下信息:
a、 所订阅的 MTC事件的类别, 如: 终端附着、 去附着、 位置变化等; b、 订阅 MTC事件的多方签约信息, 包括: 订阅 MTC事件的多个应用 服务器的地址或域名信息(以下简称为名址信息) , 比如: MTC AS1、 MTC AS2等;
c、可选地,每个应用服务器用来标识 MTC UE的外部标识( External ID )。 当然, 所有应用服务器可以使用相同的外部标识(External ID ) 来标识同一 个 MTC UE。 如果没有提供 MTC UE的外部标识 ( External ID ) , 也可以使 用 MTC UE的 MSISDN来代替;
d、 可选地, MTC-IWF的地址或域名信息。
HSS下发给 MME的 MTC业务签约数据中, 至少包括( a ) , 以便 MME 能检测 MTC终端的特定 MTC事件的发生。 或者, 还可以包括(b ) , 以便 MME能将订阅 MTC事件的多方应用服务器信息发送给 MTC-IWF。 或者, 还可以包括(d ) , 以便于 MME能发现该 MTC终端对应的 MTC-IWF , 能 将 MTC事件报告给该 MTC-IWF。
5402 , 网络检测到特定的 MTC事件发生;
如特定的 MTC事件是终端附着事件, 则网络须在 MTC UE完成附流程 后就通知 MTC事件。
对于大部分 MTC事件, MME可以检测到。 而对于某些特定的 MTC事 件,比如数据连接丟失等,可以被 PGW所检测到, 当 PGW检测到这些 MTC 事件后, 可以报告给 MME, 由 MME将所检测到的 MTC事件进行上报。
5403 , MME将 MTC事件上报给 MTC-IWF;
在该步骤中, MME向 MTC-IWF发送 MTC事件报告, 其中携带上述
MTC事件及订阅该 MTC事件的多方签约信息,即多个 MTC AS订阅该 MTC 终端的 MTC事件的信息。在具体实现时,可使用列表的方式列举订阅该 MTC 事件的多个 MTC AS的地址。
在该步骤中, 如果在 S401中 MME没有从 MTC业务签约数据中获取到 MTC-IWF 的信息, 则 MME可以根据本地配置、 漫游协议等方式获取到该 MTC UE对应的 MTC-IWF的地址或域名信息, 从而得到 MTC-IWF的具体 地址。
S404a/S404b , MTC-IWF收到 MME发送的 MTC事件报告后,根据报告 中所携带的订阅该 MTC事件的多方签约信息,将该 MTC事件相应地报告给 多个应用服务器, 如 MTC AS1、 MTC AS2。
在本应用示例中, MME将对订阅特定 MTC 事件的多方签约信息连同 MTC事件一起发送给 MTC-IWF, 由 MTC-IWF根据多方签约信息去分别发 送 MTC事件。 这种方式对 MME仍然需要一些增强, MME需要从签约数据 中提取出多方签约信息, 一并发送给 MTC-IWF。 而应用示例二、 三针对这 一点做了改进, 使得 MME无需处理多方签约信息。
应用示例二
在本应用示例中 , MTC事件的检测和上报均由 MME执行。如图 5所示 , 将 MTC事件上报给多方 MTC服务器的方法, 包括:
S501 , MTC UE请求附着到网络中; 在该 MTC UE附着成功后, 网络根 据 MTC UE的签约数据, 启动 MTC事件监控和检测功能。
在附着过程中, MME向 HSS发送位置更新报告, HSS 向 MME下载 MTC UE的签约数据;其中,在 HSS向 MME下载的 MTC UE的签约数据中, 包括 MTC业务签约数据。特别地, MTC业务签约数据包括: 所订阅的 MTC 事件的类别, 如: 终端附着、 去附着、 位置变化等;
额外地, MTC业务签约数据中还可以包括: MTC-IWF的地址或域名信 息。
S502, 网络检测到特定的 MTC事件发生;
如特定的 MTC事件是终端附着事件, 则网络须在 MTC UE完成附流程 后就通知 MTC事件。
5503 , MME将 MTC事件上报给 MTC-IWF;
在该步骤中, MME获得 MTC-IWF地址信息的方法,可釆用应用示例一 中相应方法, 在此不再进行赞述。
5504, MTC-IWF向 HSS发送签约查询请求, 查询订阅该 MTC事件的 多方签约信息; 在该步骤中,由于 MTC-IWF收到的 MTC事件报告并没有同时携带订阅 该 MTC事件的多方签约信息, 因此 MTC-IWF需要向 HSS查询订阅该 MTC 事件的多方签约信息。
典型地, MTC-IWF向 HSS发送的签约查询请求中携带: 上述 MTC UE 的内部标识信息 (如 IMSI ( International Mobile Subscriber Identification Number, 国际移动用户识别码) ); 还可以携带上述 MTC事件的类别信息;
S505, 接收到 MTC-IWF发来的签约查询请求后, HSS从上述 MTC UE 的签约信息中查询订阅该 MTC事件的多方签约信息, 通过签约查询响应返 回给 MTC-IWF;
典型地, 当签约查询请求中携带上述 MTC UE的内部标识信息和 MTC 事件的类别信息时, HSS向 MTC-IWF返回的签约查询响应中携带以下信息: a、 MTC UE的内部标识信息;
b、 上述 MTC事件的类别信息;
c、 订阅该 MTC事件的多方签约信息, 包括: 订阅该 MTC事件的多个 MTC AS的名址信息;
d、订阅了该 MTC事件的每个应用服务器用来标识该 MTC UE的外部标 识信息 (External ID ) ;
当签约查询请求中仅携带上述 MTC UE 的内部标识信息时, HSS 向 MTC-IWF返回的签约查询响应中携带以下信息:
a、 MTC UE的内部标识信息;
b、 MTC UE的签约数据;
MTC-IWF根据接收到的签约查询响应及上述 MTC事件,在签约数据中 查询订阅该 MTC事件的多方签约信息 (包括: 订阅该 MTC事件的多个 AS 的名址信息)及订阅了该 MTC事件的每个应用服务器用来标识该 MTC UE 的外部标识信息 (External ID ) ;
S506a/S506b, MTC-IWF根据接收到的订阅该 MTC事件的多方签约信 息,将该 MTC事件相应地报告给多个应用服务器,如 MTC AS1、 MTC AS2。 应用示例三
在本应用示例中 , MTC事件的检测和上报均由 MME执行。如图 6所示, 将 MTC事件上报给多方 MTC服务器的方法, 包括:
S601a/S601b, 多个 MTC服务器(如 MTC AS1、 MTC AS2等)分别向
MTC-IWF订阅针对特定 MTC UE的特定 MTC事件。 MTC-IWF存储该订阅 信息;
S602, MTC UE请求附着到网络中; 在该 MTC UE附着成功后, 网络根 据 MTC UE的签约数据, 启动 MTC事件监控和检测功能。
在该附着过程中, MME向 HSS发送位置更新报告, HSS向 MME下载
MTC UE的签约数据;其中,在 HSS向 MME下载的 MTC UE的签约数据中, 包括 MTC业务签约数据。特别地, MTC业务签约数据包括: 所订阅的 MTC 事件, 如: 终端附着、 去附着、 位置变化等;
额外地, MTC业务签约数据还可能包括: MTC-IWF的地址或域名信息。
S603 , 网络检测到特定的 MTC事件发生;
如特定的 MTC事件是终端附着事件, 则网络须在 MTC UE完成附流程 后就通知 MTC事件。
S604, MME将该 MTC事件上报给 MTC-IWF;
在该步骤中, MME获得 MTC-IWF地址信息的方法,可釆用应用示例一 中相应方法, 在此不再进行赞述。
S605a/S605b, MTC-IWF根据自身所存储的订阅该 MTC事件的多方签 约信息, 将该 MTC事件相应地报告给多个应用服务器, 如 MTC AS1、 MTC AS2。
上述应用实例一〜三中所述流程, 完全可以根据需要组合使用, 比如: 在应用实例一中,如 MME在发送 MTC事件报告时携带了订阅该 MTC事件 的多方签约信息, 则 MTC-IWF 可以直接利用该多方签约信息来发送 MTC 事件报告, 否则 MTC-IWF可以利用应用示例二中相应流程从 HSS处查询订 阅该 MTC事件的多方签约信息。 或者, 在应用示例三中, 如 MTC-IWF上已 经存储了订阅 MTC事件的多方签约信息,则 MTC-IWF可以直接使用该多方 签约信息来发送 MTC事件报告,否则 MTC-IWF亦可使用应用示例二中相应 流程向 HSS查询多方签约信息。
在上述三个应用示例中 , MTC事件的检测和报告均由 MME执行。 额外 地, 在具体应用时, MTC事件的检测也可以由 PGW或 PCRF执行。
当 MTC事件被 PGW/PCRF检测时, 可以使用类似于上述应用示例一〜 三所示的方法进行上 ·¾。 与应用实施例一〜三的不同之处在于, MME通过承 载控制信令将 MTC事件的业务签约数据传递给 PGW, 并根据需要由 PGW 进一步通过策略控制信令传递给 PCRF。比如:需检测的 MTC事件、 MTC-IWF 的地址、 订阅该 MTC事件的多方签约信息, 等等。 当 PGW/PCRF检测到特 定的 MTC事件后, PGW/PCRF可通过承载控制信令 /策略控制信令将 MTC 事件报告给 MME。 从而 , MME收集到 PGW/PCRF所检测的 MTC事件后 , 可以使用上述应用实施例一〜三的方法进行上报。
如图 7 所示, MME将 MTC 事件检测信息传递给 PGW/PCRF, 并从 PGW/PCRF收集 MTC事件报告的流程, 包括如下步骤:
5701 , MTC UE发起附着请求;
5702, MME向 HSS发起位置更新请求;
5703 , HSS返回位置更新响应,同时向 MME下载 MTC UE的签约数据, 其中包括 MTC业务签约数据;
其中, 所下载的 MTC业务签约数据包括所订阅的 MTC事件, 如: 终端 附着、 去附着、 位置变化等。 还可以包括: 订阅 MTC事件的多方签约信息, 和 /或 MTC-IWF的名址信息; 具体地, 订阅 MTC事件的多方签约信息包括: 多方 AS的名址信息及每个 AS所使用的该 MTC UE的外部标识信息( External ID ) ;
S704, MME向 PGW发起承载建立请求, 其中携带上述 MTC业务签约 数据;
S705, PGW向 PCRF发送策略控制请求, 其中携带上述 MTC业务签约 数据; 5706 , PCRF向 PGW返回策略控制响应;
5707, PGW向 MME返回 载建立响应;
5708, MME向上述 MTC UE返回附着响应。
5709, 网络打开 MTC事件监测功能;
在本步骤中, 如果 PCRF/PGW需要监测 MTC事件, 则 PCRF/PGW需 要和 MME—样打开 MTC事件监测功能;
S710-S713 , PCRF/PGW检测到 MTC事件, 相应地通过策略控制请求 / 承载控制请求, 将 MTC事件报告给 MME;
S714, MME收到 MTC事件报告后, 使用前述应用示例一〜三的方法向 MTC-IWF发送事件报告; 后续处理流程同应用示例一〜三所述, 在此不再进 行赘述。
通过上述方法, 可以使得 PGW/PCRF监控 MTC事件, 并报告给 MME, 进而由 MME向 MTC-IWF报告 MTC事件。
上述应用示例均以 E-UTRAN接入为例进行描述, 同样的实施例可以应 用到 GERAN/UTRAN接入, 在 GERAN/UTRAN接入下 , 和 MME作用等同 的是 SGSN, 和 PGW作用等同的是 GGSN。
