Description

控制 MTC设备接入及实现数据收发的方法和系统 技术领域
本发明涉及机器类型通信 ( MTC, Machine Type Communication )技术, 尤其涉及一种控制 MTC设备接入及实现数据收发的方法和系统。 背景技术
图 1为现有蜂窝无线通信系统的架构示意图, 如图 1所示, 蜂窝无线 通信系统主要由核心网(CN, Core Network )、接入网(RAN, Radio Access Network )和终端组成。 其中, 核心网负责非接入层事务, 比如终端位置更 新等, 核心网是用户面的锚点; 接入网负责接入层事务, 比如无线资源的 管理等, 接入网包括基站, 或者基站以及基站控制器, 基站之间可以根据 实际情况存在物理或逻辑上的连接, 如图 1中的基站 1和基站 2,基站 1和 基站 3之间的连接, 并且每个基站可以和一个以上的核心网节点连接; 终 端即是用户设备(UE, User Equipment ), 是指可以和蜂窝无线通信网络通 信的各种设备, 比如移动电话或笔记本电脑等。
MTC业务是指机器之间进行通信的业务, 在 MTC业务中不需要人的 参与, 所有的通信由机器自主完成。 MTC业务通过传感器等感知设备获得 数据, 然后通过通信模块将数据上报给移动通信网络, 并通过移动通信网 络接入到公共数据网, 例如在物流监控、 安全监测、 远程医疗检测、 远程 抄表等应用。 该数据由移动运营商或专门的 MTC运营商的特定 MTC服务 器进行管理, 可供 MTC用户或 MTC管理者查看。 在这个过程中, 获取业 务所需要的数据的设备即为 MTC设备。
MTC业务引入了一些与传统移动通信不同的特性,例如时间容忍特性。 时间容忍特性允许当网络负荷达到一定程度时, MTC设备延迟发送数据或 延迟对数据的接收。 在 MTC用户签约某 MTC设备为事件容忍特性时, 运 营商会在该 MTC设备的 MTC签约信息中预先设置一个负载门限, 并存储 在归属用户服务器(HSS, Home Subscriber Server )中。 HSS是电信网络中 用于保存用户或终端设备的身份信息、 认证信息和授权信息等的实体。 根 据不同情况, HSS 可用于保存用户的身份信息及用户和终端设备的绑定信 息,或只保存用户的身份信息(可由网关保存用户和终端设备的绑定信息 ), 或直接保存终端设备的身份信息。 HSS 还负责用户的签约数据库、 以及执 行用户的身份验证和授权等。 业务平台可从 HSS查询用户或终端信息。
在 MTC设备附着到网络上时, 核心网实体如移动性管理实体(MME, Mobility Management Entity )从 HSS中获得该 MTC设备的 MTC签约信息, 并保存在本地。 MME是核心网中用于管理用户终端控制信令的实体, 负责 接入控制, 包括: 鉴权控制、 标识(GUTI, TAI list )指配、 用户标识和设 备标识验证、 信令面加密、 与演进基站 (eNB, evolved Node B )之间的一 致性保护、 第二代(2G, Second Generation ) /第三代(3G, 3rd-Generation ) 与演进分组系统(EPS, Evolved Packet System )之间安全参数以及服务质 量(QoS , Quality of Service )参数的转换、 接入许可控制、 决定是否可以 获得请求的资源并预留这些资源、合法监听、移动性管理如实现对 UE当前 位置的跟踪和记录、 会话管理、 对 EPS承载的相关操作、 以及网元选择等。
在 MTC设备与 MTC服务器之间的数据通信中, 数据包在核心网通过 服务网关和分组数据网络网关进行传递。 其中, 服务网关负责对分组业务 承载的存储、 路由和数据转发, 可以作为基站间切换的锚点以及第三代合 作伙伴计划 (3GPP, The 3rd Generation Partnership Project ) 定义的接入不 同接入方式间的锚点, 并承担计费信息收集; 而分组数据网络网关负责网 络之间互联的协议( IP , Internet Protocol )地址的分配、 策略与计费规则功 能 ( PCRF, Policy and Charging Rules Function ) 的选择、 对分组业务承载 的存储和管理、 路由和数据转发、作为终端包括 MTC设备与外部网络通信 比如 MTC服务器的锚点, 同时还承担计费信息收集。
当数据从 MTC设备发送到 MTC服务器时, 数据从 MTC设备发送给 服务网关, 然后服务网关发送到分组数据网络网关, 分组数据网络网关再 将接收到的数据发送给 MTC服务器。 当数据从 MTC服务器发送给 MTC 设备时, 数据由 MTC服务器发送到分组数据网络网关, 分组数据网络网关 将接收到的数据发送到服务网关, 最后由服务网关将接收到的数据发送给 MTC设备。
目前, 在 3GPP提出的一项新的 MTC需求是时间容忍特性, 即: 允许 MTC设备在网络负荷较大时延迟其数据发送和接收。 在现有的 3GPP核心 网架构和功能中, 当网络负荷较大时有两种可能的处理方法, 第一种方法 是: 继续允许 MTC设备数据发送, 但是, 在资源上与其他终端同等竟争, 这样, 无疑降低了其他终端的服务质量, 尤其是当 MTC设备数量庞大时, 对网络资源的竟争导致原有终端的服务质量下降可能是不可接受的; 第二 种方法是: 直接拒绝 MTC设备数据的发送, 使得 MTC业务被终止。
从目前当网络负荷较大时, 对 MTC设备与 MTC服务器间实现数据收 发的方案来看, 无论是哪一种处理方式, 都不能满足 3GPP对 MTC设备提 出的新需求, 也就是说, 不能满足 MTC业务引入的时间容忍特性。 发明内容
有鉴于此,本发明的主要目的在于提供一种控制 MTC设备接入及实现 数据收发的方法和系统, 能够满足 MTC业务引入的时间容忍特性。
为达到上述目的, 本发明的技术方案是这样实现的:
一种控制 MTC设备接入的方法, 包括:
网络判断出当前负载超过预先设置的负载门限时, 阻止 MTC 设备接 入。 上述方案中, 所述阻止 MTC设备接入包括: MME在收到来自所述 MTC设备的附着请求后, 从 HSS获得 MTC签约信息或认证信息, 当前网 络负荷超过 MTC签约信息或认证信息中预先设置的负载门限时, 则 MME 拒绝所述 MTC设备的附着请求。

图 1为现有蜂窝无线通信系统的架构示意图;
图 2为本发明控制 MTC设备实现数据收发的方法的流程图; 图 3为本发明控制 MTC设备实现数据收发的系统的组成结构示意图; 图 4为本发明 MTC设备附着过程的实施例的流程示意图。 具体实施方式
图 2为本发明控制 MTC设备实现数据收发的方法的流程图,如图 2所 示, 包括以下步骤:
步骤 200: 在 MTC设备与 MTC服务器间收发数据。
当数据从 MTC设备发送到 MTC服务器时, 数据从 MTC设备发送给 服务网关, 然后服务网关发送到分组数据网络网关, 分组数据网络网关再 将接收到的数据发送给 MTC服务器; 当数据从 MTC服务器发送给 MTC 设备时, 数据由 MTC服务器发送到分组数据网络网关, 分组数据网络网关 将接收到的数据发送到服务网关, 最后由服务网关将接收到的数据发送给 MTC设备。
步骤 201 : 判断出当前网络负载超过预先设置的负载门限, 终止在 MTC 设备与 MTC服务器间收发数据。
MTC设备发送的数据可以在服务网关判断控制, 如果当前网络负载超 过在 MTC签约信息或认证信息中的预先设置的负载门限, 那么, 服务网关 终止 MTC设备发送的数据, 并向 MTC设备反馈用于指示 MTC设备停止 数据发送的反馈信息; MTC服务器发送的数据可以在分组数据网络网关判 断控制, 如果当前网络负载超过 MTC签约信息中的预先设置的负载门限, 那么, 分组数据网络网关终止 MTC服务器发送的数据, 并向 MTC服务器 反馈用于指示 MTC服务器停止数据发送的反馈信息;
也可以由服务网关或分组数据网络网关单一的实体来统一进行控制。 ΜΜΕ可以在 MTC设备附着时, 将从 HSS获得的 MTC签约信息发送 给月良务网关和 /或分组业务网络网关。
在接收到来自服务网关或分组数据网络网关的终止数据发送的反馈 后, MTC设备或 MTC服务器启动发送延迟定时器 Τ: 当延迟定时器 Τ未 超时时, MTC设备或 MTC服务器都不再次尝试数据发送, 当延迟定时器 Τ 超时时, MTC设备或 MTC服务器再次发送数据。 发送延迟定时器 Τ的定 时时长可以设定为任意值, 或者, MTC设备或 MTC服务器中保存的缺省 值。
进一步地, 在反馈信息中还可以包括延迟发送的时间或间隔。 这样, 发送延迟定时器 Τ的定时时长根据延迟发送的时间或间隔来设置, 如定时 时长为延迟发送的间隔。
负载门限可以是网元负荷率(单位百分比,比如网元负荷率达到 90% )、 或所占用的带宽、 或占用的带宽在网络提供的总带宽的比率等。 当网络负 载超过该负载门限时, 延迟 MTC业务的数据收发。 其用于延迟发送的时间 或间隔也可以作为签约数据的内容保存。
本发明方法之前还可以进一步包括: MTC设备发起附着请求或业务请 求等请求接入网络。 附着过程可以是按照现有协议规定实现, 也可以是按 照本发明方法实现。
本发明的附着过程具体实现包括:
ΜΜΕ在收到附着请求后 , 从 HSS获得 MTC签约信息或认证信息 , 如 果当前网络负荷超过 MTC签约信息或认证信息中预先设置的负载门限,则 MME拒绝 MTC设备的附着请求; 否则接受 MTC设备的附着请求。 其中, MME可以在向 MTC设备返回的附着拒绝信令中携带 MTC签约信息或认 证信息中的负载门限值。 进一步地, 在附着拒绝信令中还可以携带延迟发 送的时间或间隔。
而 MTC设备在接收到附着拒绝信令后, 同样可以启动发送延迟定时器 T, 当发送延迟定时器 T未超时时, MTC设备不再发起附着请求, 当发送 延迟定时器 T超时时, MTC设备再次发起附着请求。 如果 MME发送的附 着拒绝信令中携带有延迟发送的时间或间隔, 则发送延迟定时器 T的定时 时长根据延迟发送的时间或间隔来设置, 如定时时长为延迟发送的间隔; 如果拒绝信令中未携带延迟发送的时间或间隔, 则发送延迟定时器 T的定 时时长可以设定为任意值, 或者, MTC设备中保存的缺省值。
通过本发明方法, 在 MTC设备接入和 /或收发数据过程中, 一方面, 由于在网络负载大时, 不存在与其他终端的同等竟争, 从而提高了其他终 端的服务质量;另一方面,在满足了 MTC业务引入的时间容忍特性的同时, 最大限度地保障了 MTC业务的服务质量。

当数据从 MTC设备发送到 MTC服务器时, 核心网实体包括服务网关 和分组数据网络网关, 数据从 MTC设备发送给服务网关, 然后服务网关发 送到分组数据网络网关, 分组数据网络网关再将接收到的数据发送给 MTC 服务器。 当数据从 MTC服务器发送给 MTC设备时, 核心网实体包括分组 数据网络网关和服务网关, 数据由 MTC服务器发送到分组数据网络网关, 分组数据网络网关将接收到的数据发送到服务网关, 最后由服务网关将接 收到的数据发送给 MTC设备。
本发明系统中的 MTC设备或 MTC服务器, 还用于启动发送延迟定时 器 T, 在延迟定时器 T未超时时, MTC设备或 MTC服务器都不再次尝试 数据发送; 在延迟定时器 T超时时, MTC设备或 MTC服务器再次发送数 据。

HSS, 用于存储 MTC签约信息或认证信息, 并提供给 MME。
下面结合实施例对本发明方法进行详细描述。
图 4为本发明 MTC设备附着过程的实施例的流程示意图,本实施例中, 假设 MTC用户将其 MTC设备签约为时间容忍特性; 网络运营商为该 MTC 设备确定负载门限, 并保存在其 MTC签约信息中。 如图 4所示, 包括以下 步骤:
步骤 400: MTC设备开机后, 发起附着请求过程, 请求连接到网络。 在附着请求过程中, MTC设备发送附着请求信令给 MME: 附着请求信令 由 MTC设备发送到基站, 再由基站转发给 MME, 附着请求中携带有 MTC 设备的标识。
步骤 401: MME在收到 MTC设备的附着请求后 ,对 MTC设备进行安 全认证, 在通过对 MTC设备的认证后, MME将 MTC设备的标识发送给 HSS, 向 HSS请求 MTC签约信息。
步骤 402: HSS根据 MTC设备标识将对应的 MTC签约信息发送给 MME。
步骤 403: MME读取 MTC签约信息中的负载门限, 比较当前负载与 获得的负载门限, 如果当前负载高于负载门限, 则进入步骤 404a; 否则进 入步骤 404b。 步骤 404a: 向 MTC设备发送附着拒绝信令, 拒绝 MTC设备附着, 附 着拒绝信令中可以携带延迟发送的时间或间隔, 结束本流程。
如果 MTC设备接收到附着拒绝信令, 可以启动发送延迟定时器 T, 当 发送延迟定时器 T未超时时, MTC设备不再发起附着请求, 当发送延迟定 时器 T超时时, MTC设备再次发起附着请求。 如果 MME发送的附着拒绝 信令中携带有延迟发送的时间或间隔, 则发送延迟定时器 T的定时时长根 据延迟发送的时间或间隔来设置, 如定时时长为延迟发送的时间或间隔; 如果拒绝信令中未携带延迟发送的时间或间隔, 则发送延迟定时器 T的定 时时长可以设定为任意值, 或者, MTC设备中保存的缺省值。
步骤 404b: 向 MTC设备发送附着接受信令, MTC设备附着成功。 在 MTC设备附着成功后, 在 MTC设备与 MTC服务器间收发数据的 过程中, 如果当前网络负载超过 MTC签约信息中预先设置的负载门限, 那 么, 本发明方法会终止在 MTC设备与 MTC服务器间收发数据, 具体实施 下:
本实施例中, 假设由分组数据网络网关负责检测网络负载, 当网络负 载超过 MTC签约信息中的负载门限时,如果此时有来自 MTC设备的数据, 分组数据网络网关将不发送到 MTC服务器, 并向 MTC设备反馈用于指示 停止数据发送的反馈信息; 如果此时有来自 MTC服务器的数据时, 分组数 据网络网关将不经服务网关发送到 MTC设备, 并向 MTC服务器反馈用于 指示停止数据发送的反馈信息。 在反馈给 MTC设备或 MTC服务器的反馈 信息中可以携带延迟发送的时间或间隔。
在 MTC设备或 MTC服务器接收到用于指示停止数据发送的反馈信息 时, 可以启动延迟定时器 T, 当延迟定时器 T未超时时, MTC设备或 MTC 服务器都不再次尝试数据发送, 当延迟定时器 T超时时, MTC设备或 MTC 服务器再次发送数据。 如果反馈信息中携带有延迟发送的时间或间隔, 那 么, 延迟定时器 T的定时时长由该延迟发送的时间或间隔决定, 如为延迟 发送的间隔; 如果反馈信息中未携带延迟发送的时间或间隔, 则延迟定时 器 Τ的值设定为任意值或 MTC设备或 MTC服务器中保存的缺省值。
