Description

一种离线检测的方法、 装置及系统 本申请要求在 2010年 04月 29日 提交中 国专利局、 申请号为 201010163033.X,发明名称为"一种离线检测的方法、装置及系统"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, 特别是指一种离线检测的方法、 装置及系统。 背景技术
机器间 (Machine-to-machine, M2M )通信作为一种新型的通信理念, 其 目的是将多种不同类型的通信技术有机结合, 如: 机器对机器通信、 机器控 制通信、 人机交互通信、 移动互联通信, 从而推动社会生产和生活方式的发 展。 预计未来人对人通信的业务可能仅占整个终端市场的 1/3 , 而更大数量的 通信是机器间 (M2M )通信业务。
当前的移动通信网络是针对人与人之间的通信设计的, 如: 网络容量的 确定等。 如果希望利用移动通信网络来支持 M2M通信就需要根据 M2M通信 的特点对移动通信系统的机制进行优化, 以便能够在对传统的人与人通信不 受或受较小影响的情况下, 更好地实现 M2M通信。
一个实际的机器型通信(Machine Type Communications, MTC )终端可 以具有以下一个或多个特性: MTC终端具有低移动性; MTC终端与网络侧进 行数据传输的时间是可控的; 即 MTC终端只能在网络指定的时间段内进行接 入; MTC网络与网络侧进行的数据传输对实时性要求不高, 即: 具有时间容 忍性; MTC终端能量受限, 要求极低的功率消耗; MTC终端和网络侧之间只 进行小数据量的信息传输; MTC终端可以以组为单位进行管理; 需要对 MTC 终端的状态进行监测, 如果发现某个 MTC终端处于离线状态, 则需要通知相 应的网元设备。 对于上面所提及的需要对 MTC终端状态检测及离线通知的特性,主要的 应用场景是: 和人与人( human to human, H2H )通信不同, 由于 MTC设备 可能处于长时间的无人监测情况之下, 当 MTC设备和网络之间无法继续通信 时(可能由于链路质量变差、 也可能由于意外或人为的设备损害等), 需要系 统能够主动的检测该 MTC设备的状态并上报给相关的网元实体,以便网络能 够釆取相应的应对措施。 该特性定义了最大的离线指示检测时间 ( MAX— T— Detect ), 即从实际发生连接中断到该连接中断被检测到的最大时 间段长度, 要求系统能够在该时间段内 (基于 MTC签约信息 )检测到 MTC 设备离线事件, 该时间段长度可能是 1分钟到 1小时。
目前的通用移动通信系统 ( Universal Mobile Telecommunications System , UMTS ) 中, 针对终端设备的状态检测及通知的策略, 大致情况如下:
对于处于空闲模式的终端, 终端监听寻呼指示信道 (Paging Indicator Channel, PICH )并读取小区的系统广播信息, 同时周期性的进行位置更新。 当把终端的位置更新时间设置成离线指示检测时间, 网络侧可以通过终端发 起的周期性位置更新, 获知终端是否处于离线状态。
对于处于连接模式的终端, 存在以下几种情况:
1 )终端处于小区专用信道状态(CELL Dedicated Channel, CELL DCH ) 状态;
该状态下, 要求终端和网络必须保持空口的同步, 因此已有相应的机制 使网络能够检测上行链路质量的好坏, 比如在配置了伴随专用物理信道 ( Dedicated Physical Channel , DPCH ) 或上行非调度资源 (non-scheduling resource ) 的情况下, 基站设备基于上行数据的接收情况可以直接判断链路质 量; 在不存在伴随 DPCH或上行非调度的情况下, 基站需要通过周期性的调 度去维护链路同步。 因此, 在 CELL— DCH状态下, 网络能够及时了解终端的
2 ) 终端处于小区前向接入信道 ( CELL— Forward Access Channel , CELL FACH )状态; 该状态下, 终端设备没有被分配专用的物理资源, 在没有数据传输的情 况下, 终端无需保持上行同步, 终端需要监听下行 FACH信道或在增强的高 速分组接入 ( High speed packet access plus, HSPA+ ) 中需要监听高速下行共 享信道的共享控制信道(Shared Control Channel for HS-DSCH, HS-SCCH ), 以便及时触发上行同步建立过程进行数据的收发。 该状态下, 有周期性小区 更新机制, 网络可以通过终端发起的周期性小区更新知道终端是否处于离线 状态。
3 )终端处于小区寻呼信道( CELL Paging Channel , CELL PCH )或 UTRAN 注册区寻呼信道(UTRAN Registration Area— Paging Channel, URA— PCH )状 态;
该状态下, 终端设备没有被分配专用的物理资源, 终端只需要监听 PICH 信道,不需要保持上行同步,有数据发送的情况下,需要先转移到 CELL— FACH 状态。 该状态下, 有周期性小区更新机制, 网络可以通过终端发起的周期性 小区更新知道终端是否处于离线状态。
从上述的分析可以看出, 目前针对处于 CELL— FACH、 CELL PCH 或 URA— PCH状态的终端,虽然网络可以根据终端的周期性小区更新判断终端是 否处于离线状态, 但是由于小区更新过程终止于无线网络控制器 (Radio Network Controller , RNC ) , 因此对于处于 CELL— FACH、 CELL PCH 或 URA— PCH状态的终端,核心网并不知该终端是否离线; 同时网络侧配置的周 期性小区更新的时间是通过系统消息 1 告知终端的, 即该时间是一个小区级 别的参数, 针对该小区下所有的终端设备, 不区分需要支持 "离线指示" 的 MTC设备和普通的终端。 对于不需要支持 "离线指示" 的终端, 并不需要根 据离线检测时间来进行周期性小区更新, 尤其是当离线检测时间在分钟级时, 如果不需要支持 "离线指示" 的终端频繁的进行周期性小区更新, 极大的增 加了空口的信令负荷, 造成无线资源拥塞。 另外, 同一个小区下的 MTC设备 离线检测的时间也可能不同,但现有技术中同一小区下的所有 MTC设备使用 的是相同的离线检测时间。 基于上述情况, 针对 "离线检测及通知" 的 MTC特性, 需要对现有的机 制进行一定的改进, 才能够较优的支持该特性。 发明内容

为了解决现有技术中不需要支持 "离线指示" 的终端频繁的进行周期性 小区更新, 从而增加空口信令负荷的问题, 在本发明实施例中, 核心网配置 MTC设备的最大检测时间相关信息; MTC设备根据获取的周期性小区更新的 时间相关信息, 向 RNC发送周期性小区更新消息, 其中, MTC设备是从核 心网或者无线网络控制器 (RNC )获取确定的周期性小区更新的时间相关信 息,所述周期性小区更新的时间相关信息是根据该 MTC设备的最大检测时间 相关信息确定; RNC根据从核心网获得的 MTC设备的最大检测时间相关信 息对该 MTC设备进行离线状态检测。
参见图 1所示, 针对 RNC侧的实现过程, 本发明实施例的一种离线检测 方法包括以下步骤:
步骤 101 : RNC从核心网获得 MTC设备的最大检测时间相关信息。
这里, RNC可以接收核心网发送的 MTC设备的最大检测时间相关信息, 从而获得 MTC设备的最大检测时间相关信息,也可以接收其他节点设备转发 来的核心网发送的 MTC设备的最大检测时间相关信息。
当然, RNC也可以根据接收到的 MTC设备的最大检测时间相关信息, 向 MTC设备发送周期性小区更新的时间相关信息, 例如, 可以考虑各设备的 处理时间及传输时延等参数来确定周期性小区更新的时间相关信息, 比如, 计算最大检测时间 -RNC处理时间 -RNC与核心网之间的传输时延 -MTC设备 处理时间-基站处理时间 -MTC设备与基站传输时延的值, 将计算结果作为周 期性小区更新的时间相关信息发送给 MTC设备; 当然也可以直接将最大检测 时间相关信息作为周期性小区更新的时间相关信息发送给 MTC设备。 所述 MTC设备的周期性小区更新的时间相关信息用于 MTC设备进行周期性的小 区更新的触发。 也可以不由 RNC将接收到的 MTC设备的最大检测时间相关 信息发送给 MTC设备, 直接由核心网直接向 MTC设备发送 MTC设备的周 期性小区更新的时间相关信息,或由其他节点将核心网发送的 MTC设备的周 期性小区更新的时间相关信息转发给 MTC设备, 这样可以简化 RNC的处理 过程。
步骤 102: RNC根据所述 MTC设备的最大检测时间相关信息对该 MTC 设备进行离线状态检测。
步骤 102可以这样实现: RNC根据所述 MTC设备的最大检测时间相关 信息设定第一定时器, 例如, 在设定第一定时器时可以考虑各设备的处理时 间及传输时延等参数,比如,可以首先计算最大检测时间 -RNC处理时间 -RNC 与核心网之间的传输时延 -MTC设备处理时间-基站处理时间 -MTC设备与基 站传输时延的值, 然后设定时长为该计算结果值的第一定时器; 当然, 也可 以直接设定时长小于上述计算结果值的第一定时器。 如果在第一定时器没有 超时时, 接收到该 MTC设备发送的周期性小区更新消息或上行数据, 则确定 该 MTC设备处于在线状态, 并重启第一定时器。
步骤 102中, 如果 RNC在该第一定时器超时时, 没有接收到 MTC设备 发送的周期性小区更新消息和上行数据, 则该方法可以进一步包括: RNC根 据设定的规则确定是否需要发送离线指示给核心网, 并在确定需要发送离线 指示时, 向核心网发送该 MTC设备的离线指示信息。 这里, 设定规则具体可 以是, 如果设置的第一定时器的时长与最大检测时间的差值较大, 则等待第 一定时器超时几次后, 再发送离线指示给核心网。
参见图 2所示, 针对核心网侧的实现过程, 本发明实施例提供的一种离 线检测方法, 包括以下步骤:
步骤 201 : 核心网确定 MTC设备的最大检测时间相关信息, 并将所述 MTC设备的最大检测时间相关信息和周期性 d、区更新的时间相关信息分别提 供给 RNC和 MTC设备,所述 MTC设备的周期性小区更新的时间相关信息用 于 MTC设备进行周期性的小区更新的触发, 所述 MTC设备的最大检测时间 相关信息用于 RNC进行该 MTC设备的离线状态检测。
周期性小区更新的时间相关信息是可以根据所述 MTC设备的最大检测 时间相关信息确定。 例如, 在确定周期性小区更新的时间相关信息时可以考 虑各设备的处理时间及传输时延等参数, 比如, 可以计算最大检测时间 -RNC 处理时间 -RNC 与核心网之间的传输时延 -MTC设备处理时间-基站处理时间 -MTC设备与基站传输时延的值,将计算结果作为周期性 d、区更新的时间相关 信息; 当然, 也可以直接将最大检测时间相关信息作为周期性小区更新的时 间相关信息。 步骤 201中,将所述 MTC设备的周期性小区更新的时间相关信息提供给 MTC设备可以有多种实现方式, 比如: 核心网将所述 MTC设备的周期性小 区更新的时间相关信息直接发送给 MTC设备; 或, 核心网将所述 MTC设备 的周期性小区更新的时间相关信息发送给 RNC, RNC将所述 MTC设备的周 期性小区更新的时间相关信息发送给 MTC设备。 当然, 也可能由其他节点实 现转发处理, 这里并不做限定。
步骤 201中, 核心网获得 RNC检测到的该 MTC设备的离线指示信息, 可以这样实现: 核心网接收 RNC发送的离线指示消息, 其中含有该 MTC设 备处于离线状态的信息; 或, 核心网接收 RNC发送的现有的消息, 其中含有 将该 MTC设备处于离线状态的信息。
核心网可以根据 MTC设备的签约的最大离线指示检测时间信息, 确定 MTC设备的最大检测时间相关信息, 例如, 在确定 MTC设备的最大检测时 间相关信息时可以考虑核心网处理时延、 核心网与签约平台之间的传输时延 等参数, 比如, 可以计算 MTC设备的签约的最大离线指示检测时间信息-核 心网的处理时延-签约平台的处理时延 -核心网与签约平台之间的传输时延的 值, 将计算结果作为 MTC设备的最大检测时间相关信息; 当然, 也可以直接 将 MTC设备的签约的最大离线指示检测时间信息作为 MTC设备的最大检测 时间相关信息。 也可以参照其他参数进行确定。
步骤 202: 核心网获得 RNC检测到的该 MTC设备的离线指示信息。 在步骤 202之后,核心网可以将获得的该 MTC设备的离线指示信息通知 给 MTC服务器。
步骤 201中, 核心网也可以只确定 MTC设备的最大检测时间相关信息, 并将所述 MTC设备的最大检测时间相关信息提供给 RNC,所述 MTC设备的 最大检测时间相关信息用于 RNC进行该 MTC设备的离线状态检测以及确定 发送给该 MTC设备的周期性小区更新的时间相关信息。
参见图 3 所示, 本发明实施例提供的一种发起离线检测的方法, 包括以 下步骤: 步骤 301 : MTC设备获取核心网或 RNC确定的本 MTC设备的周期性小 区更新时间相关信息。
这里, MTC设备可以直接接收来自核心网的周期性 d、区更新的时间相关 信息, 也可以从 RNC上获得, 还可以接收其他节点设备转发来的周期性小区 更新的时间相关信息。
步骤 302: MTC设备才艮据所述周期性小区更新的时间相关信息, 向 RNC 发送周期性小区更新消息, 所述周期性小区更新消息用于 RNC进行离线状态 检测。
步骤 302可以这样实现: MTC设备根据所述周期性小区更新的时间相关 信息设定第二定时器, 并根据第二定时器向 RNC发送周期性小区更新消息。 例如, 在设定第二定时器时可以考虑各设备的处理时间及传输时延等参数, 比如,可以首先计算周期性小区更新的时间 - MTC设备处理时间 -MTC设备与 RNC/核心网的处理时间的值, 然后设定时长为该计算结果的第二定时器; 当 然, 也可以直接设定时长为周期性小区更新的时间的第二定时器。
根据第二定时器向 RNC发送周期性小区更新消息的方式可以如下: 如果 在第二定时器超时前, MTC设备成功发送了上行数据或信令, 则重启第二定 时器, 否则, 在第二定时器超时时, 向 RNC发送周期性小区更新消息, 并重 启第二定时器。
参见图 9所示, 本发明实施例由 MTC设备发起的离线检测方法, 具体包 括以下步骤:
步骤 901: 核心网配置 MTC设备的最大检测时间相关信息。
步骤 902: MTC设备根据获取的周期性小区更新的时间相关信息,向 RNC 发送周期性小区更新消息, 其中, MTC设备是从核心网或者 RNC获取确定 的周期性小区更新的时间相关信息, 所述周期性小区更新的时间相关信息是 根据该 MTC设备的最大检测时间相关信息确定。
这里,核心网可以确定 MTC设备的最大检测时间相关信息和周期性小区 更新的时间相关信息,并将所述 MTC设备的最大检测时间相关信息和周期性 小区更新的时间相关信息分别提供给 RNC和 MTC设备,所述 MTC设备的周 期性小区更新的时间相关信息用于 MTC设备进行周期性的小区更新的触发, 所述 MTC设备的最大检测时间相关信息用于 RNC进行该 MTC设备的离线状 态检测。
核心网还可以只确定 MTC设备的最大检测时间相关信息, 将所述 MTC 设备的最大检测时间相关信息提供给 RNC, RNC根据该最大检测时间相关信 息进行该 MTC设备的离线状态检测以及确定发送给该 MTC设备的周期性小 区更新的时间相关信息。 也就是说, 将所述 MTC设备的最大检测时间相关信 息提供给 RNC, RNC一方面用来进行该 MTC设备的离线状态检测, 另一方 面由 RNC根据所述 MTC设备的最大检测时间相关信息确定该 MTC设备的周 期性小区更新的时间相关信息, 并发送给该 MTC设备。
步骤 903: RNC根据从核心网获得的 MTC设备的最大检测时间相关信息 对该 MTC设备进行离线状态检测。
另夕卜,本实施例中可以按照图 1、 2和 3中示意的实施方式进行交互处理, 这里不再赘述。
以下举具体实施例, 详细描述本发明的具体实现过程。
本实施例中, MTC设备根据网络侧( RAN或核心网)配置的离线检测时 间发起周期性小区更新, RNC进行 MTC设备的离线状态检测, 在检测出离 线状态后, 通过一种新定义的信令将该事件上报给核心网, 具体参见图 4所 示。
步骤 401 : 核心网根据 MTC设备签约的 MAX— T— Detect参数, 通过 Iu 接口的无线接入网络应用协议 ( Radio Access Network Application Protocol, RANAP )信令将最大检测时间相关信息( RNC— MAX— T— Detect )相关信息通 知到 RNC, 相应的 RANAP消息可以是无线接入承载(RAB )建立消息, 如 果 MTC设备发生了跨 RNC的移动, 该信息也可以是 SRNC ( serving RNC ) 通过 Iur接口通知 DRNC ( Drift RNC ), 涉及的通知方式可能是控制面的 RSNAP消息或用户面的 FP帧。核心网在配置 RNC— MAX— T— Detect参数时需 要考虑到网络时延等因素。
步骤 402: 网络侧向 MTC 设备配置周期性小区更新的时间相关信息 ( UE— MAX— T— Detect )参数。
网络侧可以通过 RNC 或者核心网把 MTC 设备最大离线检测时间 UE— MAX— T— Detect参数配置给 MTC设备。 如果是由 RNC配置, 当 RNC收 到第一步配置的 RNC— MAX— T— Detect参数后, 根据网络环境等, 给 MTC设 备配置 UE— MAX— T— Detect, RNC可以通过 RRC连接建立、 RB建立或者 RB 重配置等消息, 通过添加新的 IE , 把该参数配置给 MTC 设备; 另外 UE— MAX— T— Detect参数也可以由核心网直接配置给 MTC设备 , 核心网根据 MAX— T— Detect 参数, 结合网络时延等因素, 可以通过 NAS 消息, 将 UE— MAX— T— Detect相关信息直接通知到 MTC设备, 如核心网可以通过位置 更新接受、 附着接受等消息把 UE— MAX— T— Detect参数配置给该 MTC设备。
步骤 403: MTC设备根据配置的 UE— MAX— T— Detect , 进行周期性的 、 区更新。
对于支持 "离线指示" 的 MTC设备, 忽略接收到的小区系统消息 1的周 期性小区更新时间,而是根据配置的 UE— MAX— T— Detect参数进行周期性的小 区更新。 具体的, MTC 设备初始化定时器取值为 0 , 该定时器运行到 UE— MAX— T— Detect时超时并停止, 如果定时器超时之前 MTC设备成功发送 了上行数据或者信令(如 UE移动切换小区触发的 CELL UPDATE过程 ), 则 重启定时器; 否则在定时器超时之时, 发送周期性小区更新, 并重启定时器。
步骤 404: RNC对相应的 MTC设备进行离线状态检测和判决。
具体的 , 针对处于 CELL— FACH、 URA PCH或 CELL— PCH状态的终端 , RNC可以基于 RNC— MAX— T— Detect设定定时器对 MTC设备进行离线检测。 一个实施例: RNC针对某个 MTC设备, 初始化定时器取值为 0, 该定时器运 行到 RNC— MAX— T— Detect时超时并停止, 如果定时器超时之前 RNC接收到 MTC设备的上行数据或者周期性小区更新, 则重启定时器; 如果在定时器超 时之时, RNC没有接收到 MTC设备的上行数据或者周期性小区更新, 根据 一定的规则进行判断并决策是否发送 "离线指示" 给核心网。
步骤 405: RNC检测到 MTC设备离线事件后, 通过新定义的 "小区离线 指示"消息将该事件通知核心网,通过 Iu接口的 RANAP信令将某 MTC设备 的 "小区离线状态" 通知给核心网。
步骤 406: 核心网对相关的信息进行汇总, 并最终形成离线的判断, 通过 新定义的 "MTC设备离线指示" 消息将该信息通知给 MTC user和 /或 MTC server。
