触发一组 MTC设备与 MTC服务器通信的方法及 MTC设备
本申请要求于 2010年 4月 30曰提交中国专利局、申请号为 201010168694.1 发明名称为"触发一组 MTC设备与 MTC服务器通信的方法及 MTC设备"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, 特别是涉及触发一组 MTC设备与 MTC服务器 通信的方法及 MTC设备。 背景技术
M2M (mach i ne-to-mach i ne,机器与机器间的通信)是指数据自动从一台终 端传送到另一台终端, 而不需要人的参与, 换言之, M2M 也就是机器与机器 的对话, M2M也被称为物联网(Internet of Things)。
在 M2M通信过程中会产生大量的 M2M信息, 这些信息需要基于通信 系统进行传输, 也就是说虽然 M2M是机器与机器之间的通信, 但是同样可 能需要网络侧的管理。 而现有的移动通信网络由于无须布线、 覆盖范围广, 成为 M2M信息承载和传送最广泛、 最有前景的技术, 并且随着移动通信网 络带宽的不断提高和终端的日益多样化, 数据业务能力不断提高, 将促使 M2M应用的发展进一步加快。
未来各行各业都将 1入 M2M通信, 同时, 针对各种不同的应用, 会有 万亿级别的海量终端引入。 如此海量终端的引入, 对网络侧的管理能力提出 了较高的要求, 同时, 增大了网络与终端之间的传输负荷。 为了能够优化网 络侧的管理能力, 并且, 优化网络与终端之间的信令 /数据传输, 可以使终端 在不需要进行数据传输的情况下, 仅与网络保持控制面的信令连接, 此时终 端仅能接收网络侧下发的指令, 但是不能进行业务层数据的传输。 这样, 当 需要终端进行业务层数据的传输时, 就需要首先将该终端 "唤醒", 也就是为 终端建立数据面的连接, 触发终端将自身的数据发送出去。 但是, 在实际应 用中, 为了完成某业务, 可能需要先触发多个终端, 此时, 关于如何触发这 多个 MTC设备, 现有技术中并没有相应的解决方案。 例如, 在针对电力系统的 M2M通信中, 为了完成获取某小区的电表度 数, 需要唤醒该小区内的所有电表向电力系统的 MTC Server ( Machine Type Communications Server, 机器类型通信服务器)传输数据。 此时, 如何触发 这些电表进行数据的发送成为需要解决的问题。 发明内容

下面将结合本发明实施例中的附图, 对本发明实施例中的技术方案进行 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所获得的 所有其他实施例, 都属于本发明保护的范围。
在本发明是实施例中, 可以基于 CBS ( Ce l l Broadca s t Shor t Mes sage , 小区广播短消息业务) 来触发多个终端。 其中, CBS 是指是以广播的方式将 信息发送给位于某个区域的所有设备, 在进行双向通讯之外的时间, 都可以 定期收到这些广播消息。 一般来说,电信业者所提供的股票行情、气象预报、 路况报导等数据, 因为收讯对象没有特殊的限制,所以都是经由 CBS来达成。
对于 CBS, J^. UMTS (Universal Mobi le Telecommuni cat ions Sys tern, 通 用移动通信系统)系统中, 其流程如图 1 所示, 即由 CBC Cell Broadcast Centre, 小区广播中心) 向 RNC (Radio Network Controller, 无线网洛控 制器) 发送 Write- Replace 消息, 其中, Wri te- Replace 消息携带有 SAI (Service Area Ident i ty,月良务区 i或标识)和 /或小区标识和 /或路由区 i或标 识 RAI , 然后由 MC (Radio Network Controller, 无线网络控制器)才艮据 SAI和 /或小区标识和 /或 RAI向指定区域 SA/RA/小区内的用户进行消息的广 播。
在 EPS (Evolved Packet System, 演进的分组系统) 系统中, 与 UMTS 系统中类似,具体的流程如图 2所示,即由 CBC向 MME( Mobility Management Entity, 移动管理实体)发送 Wri te- Replace 消息, 其中, Wri te- Replace 消息携带有设备区域标识 TAI (Tracking Area Identity, 跟踪区域标识) I 小区标识, MME将 Write- Replace消息转发给 eNB, 然后由 eNB根据 TAI/小 区标识向指定区域 TA/小区内的用户进行消息的广播。
可见, CBC需要预先获知设备区域标识, 才能够向该区域的 RNC或者 eNB 发起具体的 Write- Replace消息。 在通常的移动通信系统中, 是由移动通信 网内的网元或者应用服务器向 CBC发起广播, 而网内的网元或应用服务器需 要能够预先获取到设备区域信息。
但是, 在本发明实施例中, 发起 MTC通信倚求的是 MTC Server, 相对于 移动通信网络, MTC Server相当于是外网的网元, 并且 MTC Server只负责 接收 MTC设备发送来的数据, 而不关心 MTC设备当前所在的位置, 以及 MTC 设备是否具有移动性, 因此如何使得 CBC在发送广播消息前获取其广播区域 信息成为解决问题的关键, 本发明实施例就提供了相应的方法。
实施例一
在该实施例中, 殳所有 MTC Device已附着在 UMTS网络中, 图 3中标 识出了各网络实体间的接口,在该方案中,在 CBC和 HLR/HSS( Home Location Register/Home Subscriber Server, 归属位置寄存器归属 /用户服务器)之 间新增了 Ccb s接口, 其它接口可以复用现有的网络接口。
在本发明实施例一提供的方法中, 首先对 MTC设备进行分组, 例如, 可以从不同的维度(如: 不同的区域信息、 不同的应用、 或不同的 MTC所 有者等等)对 MTC 设备进行分组, 并且为每个组设置唯一标识该组的 ID ( MTC Group ID ), MTC Server中会存储该 MTC Group ID, 同时, 每个组 的签约信息以及各组中包含的各设备的签约信息均存放在 HLR/HSS中。
MTC Server在向 CBC发起唤醒请求时, 就可以携带需要触发的设备所 在组的 ID。 需要说明的是, 设备所在组的 Group ID并不一定能代表设备的 区域信息, 即 CBC在获知到设备的 Group ID之后, 可能无法直接发起广播 消息来触发该组中的设备, 所以需要获知到该组中设备的区域信息才可以进 行广播。
在 UMTS系统中,设备区域信息通常由 SAI (设备区域标识)或者 RAI (路 由区域标识)或者小区标识来表示,其中该 SAI由 PLMN( Public Land Mobile Network, 公共陆地移动网) ID、 LAC (Location Area Code, 艮踪区域码) 和 SAC (Service Area Code, 业务区域码)组成, 广播某消息之前, CBC需 要获知 SAI 列表、 小区标识列表或 RAI 列表中的至少一个。 其中, PL丽 ID 与发起请求的网元有关, 相对固定, i¾ SGSN ( SERVICING GPRS SUPPORT NODE, GPRS l 务支持节点)可以保存设备所在的 LAC和 SAC; 其中, 小区标识和 RAI 都可以直接从 SGS 中获取。 因此, CBC需要才艮据从 MTC Server获知的 Group ID来获取设备的 LAC和 SAC, 或者小区标识列表或者 RAI列表。
网络中的 SGSN有很多, 只有当某设备位于某 SGSN下时, 才能从通过该 SGS 获取到该设备的 LAC和 SAC, 因此, 还需要首先获知该组的设备位于哪 些 SGSN下。通常, 在 HLR/HSS中会记录有该信息, 因此, 在从 SGSN获取 LAC 和 SAC之前, 还需要向 HLR/HSS获取设备所在的 SGSN信息, 该 SGSN信息可 以是一个或者多个 SGSN标识。
也就是说, CBC在接收到 MTC Server发送的触发请求之后, 需要首先根 据设备的 MTC Group ID, 向 HLR/HSS获知设备所在的 SGSN列表, 然后再从 一个或者多个 SGSN中获知组中设备的一个或者多个 LAC和 SAC, 然后就可以 由 PLMN ID、 LAC和 SAC组成设备的 SAI , 最终再将该 SAI列表发送到 RNC , 由 RNC根据 SAI向特定的区域发起广播即可。
同样, CBC在接收到 MTC Server发送的触发请求之后, 需要根据设备的 MTC Group ID, 向 HLR/HSS获取设备所在的 SGSN列表, 然后再从一个或者多 个 SGSN中获知组中设备的小区标识列表或 RAI列表,最终再将该小区标识列 表或者 RAI列表发送到 RNC , 由 RNC根据小区标识列表或者 RAI列表向特定 的区域发起广播即可。
下面对上述方法的流程进行详细地描述。 参见图 3, 该方法包括以下步 骤:
S301 : MTC Server向 CBC发送 MTC倚求消息(可以是业务清求), 该 MTC 请求消息中携带 MTC指示 ( MTC标志位或 MTC标识等)、 MTC Group ID及触发 消息内容(即 No t i f ica t ion (通知消息), 用于指示该消息的类型为触发消 息), 该请求消息可以用短信息来发送。
S301 : MTC Server向 CBC发送 MTC请求消息,该 MTC请求消息中携带 MTC 指示 (MTC标志位或 MTC标识等)、 MTC Group ID、 通信通知消息, 还可以包 括 MTC指示信息和发起通信的随机化指示信息。 该请求消息可以用短信息来 发送。
其中, MTC指示信息用于指示指定区域内的 MTC设备接受 CBC发送广播 消息, 并且该 MTC指示消息也可以在 CBC中直接配置(如在 Mes sage ID中直 接配置 MTC Mes sage ID , 即在 Mes sage Ident i f i er中的 FFFF字段是用来定 义新业务), 或者由 MTC的网元 (如 MTC GW, MTC Server )和 CBC提前进行 协商, 如在 CBS的 Mes sage ID和 Mes s age Type中定义 MTC指示的相关信息, 从而由 MTC Server或 MTC GW将该 MTC指示信息发送给 CBC。 同理在实施例 二、 三、 四、 五、 六、 七、 八中的 MTC指示信息也可以采用同上所述的配置 方法。
其中, 发起通信的随机化指示信息用于指示该组内的 MTC设备根据该发 起通信的随机化指示信息获取随机接入时间, 在该随机接入时间内与 MTC服 务器进行通信。 对于该 MTC请求消息的类型可以在 Warning Type中 0000100 或者 0000101- 1111111进行定义。 同理在实施例二、 三、 四、 五、 六、 七、 八中的 MTC指示信息也可以釆用同上所述的配置方法。
这里需要说明的是,由于一个 SAI指示的区域内还可能包含有其他非 MTC MTC设备, 如 H2H设备等, 向一个 SAI指示的区域广播触发消息时, 除了 MTC 设备能接收到该广播消息之外, 其它非 MTC设备也能接收到, 但是, 显然对 于这些 H2H设备而言, 该请求消息是不需要接受的。 如果 H2H设备也接收该 触发消息, 也会进行一些处理, 最终发现自己该消息并不需要, 从而造成资 源上的浪费。 因此, 为了避免这种情况的发生, 在本发明的优选实施例中, 还可以由 MTC Server在发送 MTC请求消息时, 携带 MTC指示, 以此来指示该 消息是发送给 MTC设备的, 当 H2H设备接收到广播清求消息时, 如果发现带 有 MTC指示, 就可以不必接受该 MTC请求, 尽快地拒绝该请求, 从而避免浪 费的产生。
另外, 由于一组中的设备的数目可能非常大, 同时被触发时, 如果同时 向 MTC Server发送数据, 则可能会产生阻塞现象。 例如, M2M系统的一个组 中可能有亿万级别的设备, 所以如果组中设备在接收到小区广播消息后, 如 果同时向网络发起会话请求, 则该组中的所有设备同时接入网络后可能会引 起的网络拥塞问题。 为了解决该问题, 还可以由 MTC Server在发送 MTC请求 消息时, 携带发起通信的随机化接入指示信息, 这样, 该组中的各设备在接 受请求后, 可以根据随机接入指示按照一定的算法来发起会话请求, 以免拥 塞的产生。
为方便描述,该实施例一以及后续各实施例中均假设 MTC Server在发送 的 MTC请求消息中携带了 MTC指示以及随机接入指示。
其中, 对于该 MTC请求消息中的通信通知消息、 MTC指示信息以及发起 通信的随机化接入指示信息也可以分别在 CBS-Mes sage-Informa t i on-Page n 和 CBS- Mes sage- Informa t i on- Length n 进 行 定 义 。 其 中 , CBS-Mes sage-Informa t i on-Leng th n 表 明 具 体 的 消 息 长 度 , CBS-Message-Information-Page n携带具体的通信通知消息、 MTC指示信息 以及发起通信的随机化接入指示信息。 同理在实施例二、 三、 四、 五、 六、 七、 八中的 MTC指示信息和也可以釆用同上所述的配置方法。
S302: CBC 接收到该请求消息后, 向 HLR/HSS 发送 Identification Request 请求, 请求中携带 MTC Group ID, 请求获取组中设备所在的 SGSN 标识。
需要说明的是, 由于组中设备可以位于多个 SGSN下, 所以 CBC可能从 HLR/HSS中获取得到多个 SGSN的标识。
该请求消息可以用 MAP信令传输。 在 CBS协议( 23041 ) 中, CBC同其它 网元(除 MC、 丽 E之外)之间的接口以及其传输信令是没有定义的, 并且由 于 HLR / H S S支持 MAP协议, 所以只需要使 CBC支持 MAP协议, 从而就可以在 CBC和 HLR/HSS之间使用 MAP信令。
S303: HLR/HSS向 CBC返回 Identification Response, 响应中携带组中 MTC设备所在的 SGSN列表;
S304: CBC向组中设备所在的 SGSN发送 Identification Request请求 消息, 请求获取该组中 MTC设备所在的 LAC列表及 SAC列表, 或者, 小区标 识列表, 或者, RAI列表, 该请求消息用 MAP协议。
对于 CBC同 SGSN之间的请求消息, 可以用 MAP信令传输, CBC同其它网 元(除 RNC、 丽 E之外)之间的接口以及其传输信令是没有定义的, 并且由于 SGS 支持 MAP协议, 所以只需要使 CBC支持 MAP协议, 从而就可以在 CBC和 SGSN之间使用 MAP信令;
S305: SGSN向 CBC返回 Identification Response, 响应中携带组中的 设备所在的 LAC列表及 SAC列表, 或者小区标识列表, 或者 RAI列表; 需要说明的是, 一个 SGSN 下的设备也可能在不同的区域, 因此, 一个 SGS 返回的 LAC和 SAC的组合可能有多组,也可能是多个小区标识或者多个 RAL
S306: CBC 将各 SGSN 返回的 LAC 及 SAC 组合为 SAI ( SAI=PL N ID+LAC+SAC ),并向 C发送 Write- Replace请求消息, 该请求消息中携带组 中设备所在的 SAI列表或者小区标识列表或者 RAI列表、 MTC指示信息、 MTC Group ID、 通信通知消息以及发起通信的随机化接入指示信息;
同样, 对于 SGSN返回的小区标识列表或者 RAI 列表, CBC向 MC发送 Wr i t e-Rep l ace 请求消息, 该请求消息中携带组中设备所在的小区标识列表 或者 RAI列表、 MTC指示信息、 MTC Group ID、 通信通知消息以及发起通信 的随机化接入指示信息;
S307 : RNC根据接收到的 Wr i te-Rep l ace请求消息, 向所述区域中的所 有 UE发送 SMS Broadca s t Command, 该消息中携带组中设备所在的 MTC指示 信息、 MTC Group ID、 通信通知消息以及发起通信的随机化接入指示信息
S308 : RNC向 CBC返回成功响应;
S309 : 区域内的设备在接收到该请求后, 首先根据 MTC指示信息进行解 析, 如果该设备为 H2H设备, 则拒绝接受该广播消息; 如果是 MTC设备, 则 接受该广播消息, 并根据其内部存储的 search l i s t 与接收到消息中 MTC Group ID进行匹配, 如果满足, 则接受该请求消息; 如果不满足, 则不接受 该请求消息
S310: MTC 设备接受该请求消息, 同时计算出该发起通信的随机化接入 指示请求的具体内容或者随机接入时间;
S311 - S312 : MTC 设备根据随机接入时间向 MTC Server 发送会话请求 Ses s ion Reques t。
可见, 在该实施例一中 CBC能够获知设备的区域信息, 并进而向 RNC发 起广播请求, 从而实现了触发一组 MTC设备发送数据。 进一步的, 由于携带 了 MTC指示及发起通信的随机化接入指示, 减少了区域内非 MTC设备的消息 处理开销, 并且可以避免产生网络拥塞。
实施例二
实施例一是用 CBC根据设备所在的 Group ID获取设备的区域信息,在该 实施例二中, 为了减少对 CBC的增强, 避免过多地占用 CBC的资源, 还可以 使用一个独立的网元(该网元同时具备 MTC Server与 3GPP接口之间的功能, 即 Interworking Function, 如 MTC GW、 MTC Server或者其它具有代理功能 的实体 ) 来根据设备所在的 MTC Group ID获取设备的区域信息, 然后由该网 元将获取到的设备区域信息发送给 CBC, CBC直接根据设备的区域信息向 MC 发起广播请求即可。
参见图 4, 该实施例二的前提是所有 UE附着在 UMTS网络中。 并且在该 流程图中增加了 MTC 网关 ( GW, GateWay ), 在该 MTC GW上增加了获取 SGGN 和 SAI标识的模块。 同时, 该流程图中标识出了各网络实体之间的接口, 即 新增了 MTC Server与 MTC GW之间的接口 MGi, MTC GW与 HLR/HSS之间的接 口 MGc, MTC GW与 MME之间的接口 G- M2M, 其他都可以复用网络实体之间现 有的接口。 当然, 该 MTC网关的功能也可以由 MTC服务器来全部完成。
具体流程包括:
S401: MTC Server向 MTCGW发送 MTC请求消息, 该请求消息中携带 MTC 指示信息、 MTC Group ID、 通信通知消息以及发起通信的随机化接入指示信 息, 该请求消息可以用短信息来发送。
S402: MTC GW 向 HLR/HSS发送 Identification Request奇求消息,请 求中携带 Group ID, 请求获取组设备所属的 SGSN标识列表; 该请求消息使 用 MAP信令;
S403: HLR/HSS向 MTC GW返回 Identification Response响应, 响应中 携带该组中所有设备所属的 SGSN标识列表;
S404: MTC GW在接收到组设备所述的 SGSN标识后, 向所述的 SGSN发送 Identification Request倚求消息, 请求消息中携带 MTC Group ID, 请求获 取组中设备所述的 SAC列表和 LAC列表,或者小区标识列表,或者 RAI列表, 该请求采用 Diameter协议;
S405: SGSN向 MTCGW返回 Identification Response, 响应中携带组中 设备所属的 SAC列表及 LAC列表, 或者, 小区标识列表, 或者, RAI列表;
S406: MTC GW向 CBC发送 SMS请求消息,请求消息中携带 MTC指示信息、 MTC Group ID、 通信通知消息以及发起通信的随机化接入指示信息, 同时携 带 SAI list、 小 区标识列表或 RAI 列表中的至少一个, 其中 SA I =PLMN- 1 D+SAC+TAC; 该消息可以用短消息来发送;
S407: CBC向 RNC发送 Write- Replace请求消息, 该请求消息中携带组 中设备所在的 SAI列表、 小区标识列表或 RAI列表中的至少一个 , MTC指示 信息、 MTC Group ID、 通信通知消息以及发起通信的随机化接入指示信息, 该消息支持 MAP协议;
S408: RNC向 SAI列表、 小区标识列表或 RAI列表中的所有 UE发送 SMS Broadcast Command, 该消息中携带 MTC指示信息、 MTC Group ID、 通信通知 消息以及发起通信的随机化接入指示信息;
S409: RNC向 CBC返回成功响应;
S410: 区域内的设备在接收到该请求后, 首先根据 MTC指示信息进行解 析, 如果该设备为 H2H设备, 则拒绝接受该广播消息; 如果是 MTC设备, 则 接受该广播消息, 并根据其内部存储的 search list 与接收到消息中 MTC Group ID进行匹配, 如果满足, 则接受该请求消息; 如果不满足, 则不接受 该请求消息
S411: MTC Device接受该请求消息, 同时计算出该触发请求的具体内容 以及随机接入时间数;
S412: MTC Device 才艮据随机接入时间创建 Session Request, 向 MTC Server发送数据, 其中该 MTC Device可以是该组中的一个或者多个 MTC设 备。
可见, 在该实施例二中, 由于提供了专门用于获取设备区域信息的网絡 实体 MTCGW, 因此使得 CBC可以专注于完成最基本的操作, 避免过多地占用 CBC的资源。
其中, 新增加的 MTC GW用来完成以下三个功能:
1 ) 向 HLR/HSS获取 Group ID指示的组设备所属的 SGSN标识;
2 ) 向 SGSN中获取 Group ID指示的组设备所属的区域标识 SAI;
3) 向 CBC发送请求消息, 请求消息中携带 MTC指示、 MTC Group ID, 触 发消息内容以及设备接入网络的随机接入指示, 同时携带 SA I List; 在该实施例二中, 该 MTC GW的所有功能也可以直接由 MTC Server来完 成。
实施例三
在前述实施例一与实施例二中, 均以 SAC、 LAC、 小区标识或 RAI保存在 SGSN为例进行的介绍。 但是, 在实际的 M2M应用中, 有些低移动性 MTC设备 (如电表等), 设备的 SAC、 LAC或者, 小区标识、 RAI都比较固定, 因此设 备的 SAC、 LAC, 小区标识或 RAI可能就直接保存在 HLR/HSS中; 也就是说, 当需要唤醒大量的低移动性设备时, 可以直接从 HLR/HSS获知到设备的 SAC 列表和 LAC列表, 或者, 小区标识列表, 或者, RAI 列表。 此时, 相应的流 程会有所简化, 具体的, 参见图 5, 包括以下步骤:
S501: 同实施例一中的步骤 S301
S502: CBC向 HLR/HSS发送 Identification Request,请求获取该 Group ID中设备所在的 SAC列表和 LAC列表, 或者, 小区标识列表, 或者, RAI列 表;
S503: HLR/HSS向 CBC返回 Identification Response, 响应中携带 SAC 标识列表和 LAC标识列表, 或者, 小区标识列表, 或者, RAI列表;
S504 ~ S510: 同实施例一中的步骤 S306 ~ S312.
实施例四
针对该实施例三所描述的情形, 同样也可以釆用类似实施例二的方式, 即提供一个独立的网絡实体 MTC GW 用于获取设备的区域信息, 然后发送给 CBC, 由 CBC向 RNC发起广播请求。 其中, 该 MTC GW所实现的所有功能都可 以由 MTC Server来完成。 参见图 6, 具体的流程包括:
S601: 同实施例二中的步骤 S401
S602: MTC GW向 HLR/HSS发送 Identification Request, 请求获取该 Group ID中设备所在的 SAC列表和 LAC列表, 或者, 小区标识列表, 或者, RAI列表;
S603: HLR/HSS向 MTC GW返回 Ident ificat ion Response, 响应中携带 SAC标识列表和 LAC标识列表, 或者, 小区标识列表, 或者, RAI列表; S604 ~ S610: 同实施例二中的步骤 S406 ~ S412。 实施例五
前述各实施例均以 MTC设备附着在 UMTS网络进行的介绍,在实际应用中, MTC设备也可以附着在 EPS网络中, 具体的实现方法与在 UMTS网络中类似, 只是具体涉及的网络实体以及详细的流程略有不同, 下面对此进行介绍。
参见图 7, 该实施例五提供的方法包括以下步骤:
首先, 该实施例五的前提是所有 MTC设备已附着在 EPS网络中, 并且在 图 Ί中标识出了各网络实体间的接口, 在该方案中, 在 CBC和 HLR之间新增 了 Ccbs接口, 其它接口复用现有的网络接口。
S701: MTC Server向 CBC发送 MTC请求消息, 该 MTC请求消息中携带 MTC指示 (MTC标志位或 MTC标识等)、 MTC Group ID、 通信通知消息, 还可 以包括 MTC指示信息和发起通信的随机化指示信息。 该请求消息可以用短信 息来发送。
其中, MTC指示信息用于指示指定区域内的 MTC设备接受 CBC发送广播 消息, 并且该 MTC指示消息也可以在 CBC中直接配置(如在 Message ID中直 接配置 MTC Message ID, 即在 Message Identifier中的 FFFF字段是用来定 义新业务), 或者由 MTC的网元 (如 MTC GW, MTC Server )和 CBC提前进行 协商, 如在 CBS的 Message ID和 Message Type中定义 MTC指示的相关信息, 从而由 MTC Server或 MTC GW将该 MTC指示信息发送给 CBC。 同理在实施例 二、 三、 四、 五、 六、 七、 八中的 MTC指示信息也可以釆用同上所述的配置 方法。
其中, 发起通信的随机化指示信息用于指示该组内的 MTC设备根据该发 起通信的随机化指示信息获取随机接入时间, 在该随机接入时间内与 MTC服 务器进行通信。 对于该 MTC请求消息的类型可以在 Warning Type中 0000100 或者 0000101- 1111111进行定义。 同理在实施例二、 三、 四、 五、 六、 七、 八中的 MTC指示信息也可以釆用同上所述的配置方法。
这里需要说明的是,由于一个 SAI指示的区域内还可能包含有其他非 MTC 设备, 如 H2H设备等, 向一个 SAI指示的区域广播触发消息时, 除了 MTC设 备能接收到该广播消息之外, 其它非 MTC设备也能接收到, 但是, 显然对于 这些 H2H设备而言, 该请求消息是不需要接受的。 如杲 H2H设备也接收该触 发消息, 也会进行一些处理, 最终发现自己该消息并不需要, 从而造成资源 上的浪费。 因此, 为了避免这种情况的发生, 在本发明的优选实施例中, 还 可以由 MTC Server在发送 MTC请求消息时, 携带 MTC指示, 以此来指示该消 息是发送给 MTC设备的, 当 H2H设备接收到广播请求消息时, 如果发现带有 MTC指示, 就可以不必接受该 MTC请求, 尽快地拒绝该请求, 从而避免浪费 的产生。
另外, 由于一组中的设备的数目可能非常大, 同时被触发时, 如果同时 向 MTC Server发送数据, 则可能会产生阻塞现象。 例如, M2M系统的一个组 中可能有亿万级别的设备, 所以如果组中设备在接收到小区广播消息后, 如 杲同时向网络发起会话请求, 则该组中的所有设备同时接入网络后可能会引 起的网络拥塞问题。 为了解决该问题, 还可以由 MTC Server在发送 MTC请求 消息时, 携带发起通信的随机化接入指示信息, 这样, 该组中的各设备在接 受请求后, 可以根据随机接入指示按照一定的算法来发起会话请求, 以免拥 塞的产生。
为方便描述,该实施例一以及后续各实施例中均 支设 MTC Server在发送 的 MTC请求消息中携带了 MTC指示以及随机接入指示。
其中, 对于该 MTC请求消息中的通信通知消息、 MTC指示信息以及发起 通信的随机化接入指示信息也可以分别在 CBS-Message-Information-Page n 和 CBS- Message- Information- Length n 进 行 定 义 。 其 中 , CBS-Message-Information-Length n 表 明 具 体 的 消 息 长 度 , CBS-Message-Information-Page n携带具体的通信通知消息、 MTC指示信息 以及发起通信的随机化接入指示信息。 同理在实施例二、 三、 四、 五、 六、 七、 八中的 MTC指示信息和也可以采用同上所述的配置方法。
S702: CBC 接收到该诸求消息后, 向 HLR/HSS 发送 Identification Request请求, 请求中携带 MTC Group ID, 请求获取组中设备所在的 MME标 识列表。 因为组中设备可以位于多个丽 E下, 所以 CBC可以从 HLR/HSS中获 取得到多个 MME的标识。 该请求消息可以用 MAP信令传输。 在 CBS协议( 23041 ) 中, CBC同其它 网元(除 MC、 丽 E之外)之间的接口以及其传输信令是没有定义的, 并且由 于 HLR / H S S支持 MAP协议, 所以只需要使 CBC支持 MAP协议, 从而就可以在 CBC和 HLR/HSS之间使用 MAP信令;
S703: HLR/HSS向 CBC返回 Identification Response, 响应中携带组中 设备所在的 MME标识列表;
S704: CBC向组中设备所在的 MME发送 Identification Request请求消 息, 请求获取组中设备所在的 TAI列表或小区标识列表 (如 ECGI ( E-UTRAN Cell Global Identity ) 等), 该请求消息可以使用 SBc- AP协议发送。
S705: 匪 E向 CBC返回 Identification Response, 响应中携带组中的设 备所在的 TAI列表或小区标识列表;
S706: CBC向 MME发送 Wr i te- Replace请求消息, 该请求消息中携带組 中设备所在的 TAI 列表或小区标识列表, MTC指示信息、 MTC Group ID、 通 信通知消息以及发起通信的随机化接入指示信息;
实际上最终进行广播的是 eNodeB, 但是与 UMTS 系统中不同的是, CBC 并不是直接将 Wr i te-Replace请求消息发送给相关的 eNodeB,而是需要由 MME 进行转发; 该请求消息使用 SBc- AP协议;
S707: MME向 eNodeB发送 Write- Replace请求消息, 该请求消息中携带 TAI列表或小区标识列表, MTC指示信息、 MTC Group ID, 通信通知消息以及 发起通信的随机化接入指示信息; 该请求消息使用 S卜 AP协议;
S708: eNodeB 向 TAI 或小区标识指示的区域中的所有 UE 发送 S S Broadcast Command, 该消息中携带 MTC指示信息、 MTC Group ID、 通信通知 消息以及发起通信的随机化接入指示信息;
S709: eNodeB向 MME返回 Response-Success成功响应;
S710: MME向 CBC返回 Response- Succes s成功响应;
S711: 区域内的设备在接收到该请求后, 首先根据 MTC指示信息进行解 析, 如果该设备为 H2H设备, 则拒绝接受该广播消息; 如果是 MTC设备, 则 接受该广播消息, 并根据其内部存储的 search list 与接收到消息中 MTC Group ID进行匹配, 如果满足, 则接受该请求消息; 如果不满足, 则不接受 该请求消息
S712: MTC Device接受该请求消息, 同时计算出该触发请求的具体内容 以及随机接入时间;
S713: MTC Device 根据随机接入时间向 MTC Server 发送 Session Reques t。
实施例六
与前述实施例二相似, 在 EPS系统中, 同样可以提供一个专门用于获取 设备区域信息的网络实体 MTC GW。 参见图 8, 该方案的前提是所有 UE附着在 EPS网络中。 并且在该图 8中 增加了 MTC GW, 在该 MTC GW上增加了获取匪 E和 TAI标识的模块, 同时, 上述流程图中标识出了各网絡实体之间的接口, 即新增了 MTC Server与 MTC GW之间的接口 MGi, MTC GW与 HLR/HSS之间的接口 MGc, MTC GW与 MME之间 的接口 S-M2M, 其他都复用网络实体之间现有的接口。 同样, 在该实施例中, MTC GW所实现的功能可以由 MTC Server来完成。
S801: MTC Server向 MTCGW发送 MTC请求消息, 该请求消息中携带 MTC 指示信息、 MTC Group ID、 通信通知消息以及发起通信的随机化接入指示信 息, 该请求消息可以用短信息来发送;
S802: MTC GW 向 HLR/HSS发送 Identification Request请求消息,请 求中携带 MTC Group ID, 请求获取该组中设备所属的 MME标识列表; 该请求 消息使用 MAP信令;
S803: HLR/HSS向 MTC GW返回 Identification Response响应, 响应中 携带该组中所有设备所属的丽 E标识列表;
S804: MTC GW在接收到组设备所述的 MME标识后, 向所述的 MME发送 Identification Request请求消息, 请求消息中携带 MTC Group ID, 请求获 取组中设备所述的 TAI列表或小区标识列表, 该请求采用 Diameter协议; S805: MME向 MTC GW返回 Ident if icat ion Response, 响应中携带组中 设备所属的 T A I列表或 、区标识列表;
S806: MTC GW向 CBC发送 SMS请求消息,请求消息中携带 MTC指示信息、 MTC Group ID, 通信通知消息以及发起通信的随机化接入指示信息示, 同时 携带 TAI List或小区标识列表; 该消息可以用短消息来发送;
可见, 新增加的 MTC GW用来完成以下三个功能:
1 ) 向 HLR/HSS获取 Group ID指示的组设备所属的 MME标识;
2 ) 向 MME中获取 Group ID指示的组设备所属的区域标识;
3 )向 CBC发送请求消息, 请求消息中携带 MTC指示信息、 MTC Group ID、 通信通知消息以及发起通信的随机化接入指示信息, 同时携带 TA I L i s t或小 区标识;
S807 - S814与步骤 S706 ~S713相同, 这里不再赞述。
实施例七
与实施例三相似, 在 EPS系统中, 同样可能存在移动性较低的设备, 此 时, 设备的区域信息 TAI或小区标识就直接保存在 HLR/HSS中, 设备的 TAI 或小区标识比较固定,因此设备的 TAI或小区标识可能就直接保存在 HLR/HSS 中; 也就是说, 当需要唤醒大量的低移动性设备时, 可以直接从 HLR/HSS获 知到设备的 TAI或小区标识, 而不用再通过 MME获知。 此时, 相应的流程会 有所简化, 具体的, 参见图 9, 包括以下步骤:
S901: 同实施例五中的步樣 S701;
S902: CBC向 HLR/HSS发送 Identification Request, 请求获取组中设 备所在的 TAI列表或小区标识列表;
S903: HLR/HSS向 CBC返回 Identification Response, 响应中携带组中 设备所在的 TAI列表或小区标识列表;
S904 -S911: 同实施例五中的步骤 S706 ~ S713。
实施例八

S1002: MTC GW向 HLR/HSS发送 Identification Request, 请求获取该 MTC Group ID中设备所在的 TAI列表或小区标识列表;
S1003: HLR/HSS向 MTCGW返回 Identification Response, 响应中携带 所在的 TAI列表或小区标识列表;
S1004 ~ S1012: 同实施例六中的步骤 S806 ~ S814。 综合以上实施例一、 三、 五、 七提供的技术方案, 参见图 11, 本发明实 施例提供的触发一组 MTC设备与 MTC服务器进行通信的方法包括以下步骤:
