本发明涉及但不限于机器通信领域领域，尤其涉及更新资源通告的方法、本地公共业务实体及系统。
背景技术
M2M(Machine to Machine)通信网络由各个M2M节点和承载网络组成。M2M节点通过承载网络实现互相通信，一个M2M节点至少包含一个应用实体(AE，Application Entity)或者一个公共业务实体(CSE，Common Service Entity)。应用实体是执行实际M2M应用的逻辑单元，公共业务实体是对应用进行管理和服务的逻辑单元。
M2M应用之间的通信是通过公共业务实体CSE之间的交互来实现，M2M应用通过X接口连接到CSE，CSE之间通过Y接口进行通信，而通信的前提是M2M应用首先需要在本地CSE进行注册，然后才能通过CSE之间的通信实现M2M应用的交互，如图1所示M2M系统架构图：
在M2M系统架构中，应用节点是末端的执行节点，例如智能电表，温度测控传感器，火警报警器，智能家电等等，中间节点是连接末端执行节点到网络侧服务器的中间件，例如网关，基础节点是网络侧的服务器。
在实际应用中，应用节点上的应用实体相关资源需要注册到应用节点上的公共业务实体，而不需要注册到中间节点的公共业务实体和基础节点的公共业务实体，而为了方便中间节点上的应用实体能查找到应用节点上的资源，特使用资源通告的方式，在中间节点上创建与应用节点上的原始资源相应的通告资源，通告资源有着跟原始资源相同的搜索标签，并有原始资源的链接，使得中间节点上的应用可以方便的搜索到需要的资源，并根据链接访问原始资源。
一般的资源通告过程只能支持将资源通告到注册在拥有资源的CSE的远程CSE上，对于未注册的远程CSE，例如基础节点的CSE，不能执行资源通告的过程。当基础节点上的应用需要搜索应用节点上的资源信息时，需要首 先向连接到基础节点上的所有中间节点发送搜索请求，然后由中间节点将搜索结果反馈给基础节点。然而，随着日益增长的M2M应用，M2M应用节点和中间节点也会日益增长，导致基础节点搜索时会占用大量的资源和时间。因此，需要一种通告传播方法，可以将拥有资源的CSE通告到未注册的远程CSE上的，使得远程CSE上的应用实体也可以方便快捷的访问需要的资源。
上述内容仅用于辅助理解本发明的技术方案，并不代表承认上述内容是现有技术。

本发明目的的实现、功能特点及优点将结合实施例，参照附图做进一步说明。
本发明的较佳实施方式
应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
为了便于阅读和叙述，本地公共业务实体简写为CSE1，本地应用实体AE1，公共业务实体简写为CSE。
参照图2，图2为本发明更新资源通告的方法第一实施例的流程示意图。
在第一实施例中，该更新资源通告的方法包括：
步骤S10，CSE1接收AE1发送的更新资源请求消息，读取所述请求消息中的通告参数，该通告参数包括需要通告到的远程CSE的标识或地址；
步骤S20，CSE1向所述远程CSE发送创建通告资源请求消息，所述创建通告资源请求消息包括通告资源的标识或地址、被通告资源的搜索标签和所述通告参数；
所述远程CSE为一个或多个，当远程CSE为一个时，CSE1只向一个远程CSE发送创建通告资源请求消息，当远程CSE为多个时，CSE1向所有远程CSE发送创建通告资源请求消息，远程CSE与CSE1直接相邻或相距一定数量的相邻的公共业务实体；所述创建通告资源请求消息包括被通告资源的标识或地址，被通告资源的搜索标签和所述通告参数，便于远程CSE对被通告资源进行搜索和访问。
步骤S30，CSE1接收远程CSE在创建通告资源后发送的指示通告资源创建成功的响应消息，更新AE1的资源属性。
远程CSE接收到CSE1发送的创建通告资源请求消息后，检测通告参数中是否该远程CSE的标识或地址，若有，则验证CSE1的权限，判断CSE1是否具有指示远程CSE创建资源的权限，若有权限，远程CSE则创建资源，并向CSE1发送指示资源创建成功的响应消息，CSE1接收到指示资源创建成功的响应消息后，更新资源的属性“通告到”，即将远程CSE的标识或地址添加到属性“通告到”中。
在本实施例中，通过接收AE1发送的更新资源请求消息，读取所述请求消息中的通告参数，并向所述远程CSE发送创建通告资源请求消息，远程CSE创建通告资源并向CSE1发送指示资源创建成功的消息响应，以供CSE1更新AE1的资源属性，从而解决一般的通告方法不能将拥有资源的CSE通告到未注册的远程CSE上的技术问题。
参照图3，图3为本发明更新资源通告的方法第二实施例的流程示意图。
在第二实施例中，若远程CSE为多个时，步骤S20包括：
步骤S40，CSE1发送创建通告资源请求消息至距离CSE1最近的远程CSE，以供多个所述CSE逐级转发所述创建通告资源请求消息，直至发送至与CSE1距离最远的远程公共业务实体。
若远程CSE为多个，CSE1首先向距CSE1最近的远程CSE发送创建通告资源请求消息，最近的远程CSE接收到创建通告资源请求消息后，经过步骤S30，返回给CSE1指示资源创建成功的消息响应，以更新AE1的资源属性；离CSE1最近的远程CSE逐级向离CSE1远的远程CSE发送创建通告资源请求消息，直至距离CSE1最远端的远程CSE接收到所述创建通告资源请 求消息，经步骤S30处理向CSE1返回指示资源创建成功的消息响应，以逐步更新AE1的资源属性，提示AE1所需通告的资源更新到的位置。
参照图4，图4为本发明更新资源通告的方法第三实施例的流程示意图。
在第三实施例中，在步骤S10之后，所述更新资源通告的方法还包括：
步骤S50，CSE1判断需要通告到的所述远程CSE是否已接收到创建通告资源请求消息，若否，则CSE1向远程CSE发送创建通告资源请求消息。
CSE1读取创建通告资源请求消息中的通告参数，检测更新资源是否对通告参数中的远程CSE进行过通告，若未通告过，则发送创建通告资源请求消息给远程CSE；若已通告过，则不向远程CSE发送创建通告资源请求消息，这样避免了向已经通告过的远程CSE重复发送创建通告资源请求消息，避免了不必要的创建通告资源请求消息在网络上传输，减小了网络拥塞。
参照图5，图5为本发明更新资源通告的方法第四实施例的流程示意图。
在第四实施例中，在步骤S20之后，所述更新资源通告的方法还包括：.
步骤S601，远程CSE接收到所述创建通告资源请求消息后，检查所述通告参数中是否包括所述远程CSE的标识或地址，若是，则验证CSE1的权限；
步骤S602，远程CSE若验证CSE1有权限，则创建通告资源，并向CSE1发送指示通告资源创建成功的响应消息，以供CSE1更新AE1的资源属性。
远程CSE接收到所述创建通告资源请求消息后，检查所述通告参数中是否包括所述远程CSE的标识或地址，若没有该远程CSE的标识或地址，则意味着该远程CSE无需进行资源更新，则不作相关处理；若有通告参数中有该远程CSE的标识或地址，则开始验证CSE1的权限。
参照图1和图9，AE1注册到CSE1，CSE1是AE1的本地CSE，CSE2是中间节点，CSE3是基础节点，CSE2和CSE3是相对于CSE1的远程CSE。
本发明实施例更新资源通告的方法应用创建通告资源请求消息的两个远程CSE的流程如下：
1、应用实体AE1发送更新资源请求消息给本地公共业务实体CSE1，请求消息中包含通告参数；
通告参数包括用于指示需要通告到的远程CSE，该参数可以包含一个或多个远程CSE的标识或地址，在本实施例中设置为CSE2和CSE3的标识或地址；
2、如果更新资源请求中包含通告参数，则CSE1检查请求更新的资源是否已经在通告参数中的远程CSE上通告过，如果未通告过，则发送创建通告资源请求消息给CSE2，创建通告资源请求消息中包含：
1)原始资源“Resource-AE1”(即被通告的资源)的地址或标识；
2)原始资源“Resource-AE1”的搜索标签；
3)通告参数：与更新资源请求中的通告参数值相同；
3、CSE2接收到创建通告资源请求消息后，检查通告参数中是否包含CSE2的标识或地址，如果有，则验证CSE1的权限，验证通过后，创建资源“AE1-Annc”，发送指示资源创建成功的响应消息给CSE1；
4、CSE1接收到指示资源创建成功地响应消息后，更新资源“Resource-AE1”的属性“通告到”，即将CSE2的标识或地址添加到属性“通告到”中。
5、CSE2读取通告参数中包含有CSE3的标识或地址，发送创建通告资源请求消息给CSE3，创建通告资源请求消息中包含：
1)原始资源的地址或标识：原始资源“Resource-AE1”在CSE1上的地址或标识；
2)原始资源的搜索标签；
6、CSE3接收到CSE2发送的创建通告资源请求消息后，对CSE2的权限验证通过后，创建通告资源“AE1-Annc”。
7、CSE3发送响应消息到CSE1，指示成功创建通告资源；
8、CSE1在接收到CSE3的响应消息后，如果响应消息中指示成功创建通告资源，则将CSE3标识或地址添加到资源“Resource-AE1”的属性“通告到”。
可选地，参照图1和图10，AE1注册到CSE1，CSE1是AE1的本地CSE，CSE2是中间节点，CSE3是基础节点，CSE2和CSE3是相对于CSE1的远程CSE；并且，创建通告资源请求消息为资源递送消息，所述资源递送消息包 括以下属性：
发起实体属性，其设置为CSE1；
目标实体属性，其设置为远程CSE；
数据属性，其设置为所述创建通告资源请求消息，包括被通告资源的标识或地址、被通告资源的搜索标签和所述通告参数。
本发明实施例更新资源通告的方法应用资源递送消息的两个远程CSE的流程如下：
1、应用实体AE1发送更新资源请求消息给本地公共业务实体CSE1，请求消息中包含通告参数；
通告参数：指示需要通告到的远程CSE，该参数可以包含一个或多个远程CSE的标识或地址，在本实施例中设置为CSE2和CSE3的标识或地址；
2、CSE1接收到更新资源请求消息后，读取请求消息中包含的通告参数，检查请求更新的资源是否已经在通告参数中的远程CSE上通告，如果未通告，则发送创建通告资源请求消息给该CSE2，创建通告资源请求消息中包含：
1)原始资源“Resource-AE1”(即被通告的资源)的地址或标识；
2)原始资源“Resource-AE1”的搜索标签；
3、CSE2接收到创建通告资源请求消息后，并对CSE1的权限验证通过后，创建资源“AE1-Annc”，并发送响应消息给CSE1，响应消息中指示资源创建成功；
4、CSE1接收到响应消息后，如果响应消息中只是资源创建成功，则更新“Resource-AE1”的属性“通告到”；“通告到”属性用来指示成功通告了的远程CSE的标识或地址，更新属性“通告到”即将CSE2的标识或地址添加到“通告到”属性中。
5、如果通告参数中的远程CSE3未在CSE1上注册，则CSE1创建资源“递送1”，并设置资源“递送1”的属性：
1)属性“发起”设置为CSE1；
2)属性“目标”设置为CSE3；
3)属性“数据”设置为创建通告资源的请求，创建通告资源的请求中包含的信息与上述步骤2中相同；
6、CSE1发送创建递送资源请求消息给CSE2，请求消息中包含CSE1创 建的资源“递送1”的属性。
7、CSE2接收到创建递送资源请求消息后，并对CSE1的权限验证通过后，创建资源“递送2”，并设置资源“递送2”的属性：
1)属性“发起”设置为CSE1；
2)属性“目标”设置为CSE3；
3)属性“数据”设置为创建通告资源的请求；
8、CSE2发送创建递送资源请求消息给CSE3，请求消息中包含CSE2创建的资源“递送2”的属性。
9、CSE3接收到创建递送资源请求消息后，对CSE2的权限验证通过后，创建资源“递送3”，并设置资源“递送3”的属性：
1)属性“发起”设置为CSE1(本地CSE)；
2)属性“目标”设置为CSE3(资源需要通告到的CSE)；
3)属性“数据”设置为创建通告资源的请求；
10、CSE3读取属性“数据”中的创建通告资源的请求，创建通告资源“AE1-Annc”。
11、CSE3发送响应消息到CSE1，指示成功创建通告资源。
12、CSE1在接收到CSE3的响应消息后，如果响应消息中指示成功创建通告资源，则将CSE3标识或地址添加到资源“Resource-AE1”的属性“通告到”。
在本可选方案中，CSE1向远程CSE发送资源递送消息，利用资源递送消息替换创建通告资源请求消息，所述资源递送消息包括发起实体属性、目标实体属性及数据属性；CSE1接收远程CSE在创建通告资源后发送的指示通告资源创建成功的响应消息，更新本地应用实体的资源属性，这样，CSE1将资源递送消息发送给指定的远程CSE，然后由最近的远程CSE相远端的远程CSE逐级转发，CSE1发送一次资源递送消息后仅接收远程CSE返回的消息响应，并根据远程CSE返回的响应消息实时更新资源递送消息已经传送到的位置，避免因CSE1等待过久而重复发送资源递送资源，减少了网络拥塞。
此外，本发明实施例还提供一种更新资源通告系统，参照图6，图6为本发明实施例更新资源通告系统结构示意图。

参照图7，图7为本发明本地公共业务实体第一实施例的功能模块示意图，所述CSE1包括：
接收读取模块70，设置为接收本地应用实体发送的更新资源请求消息，读取所述请求消息中的通告参数，该通告参数包括需要通告到的远程CSE的标识或地址；

远程CSE接收到CSE1发送的创建通告资源请求消息后，检测通告参数中是否该远程CSE的标识或地址，若有，则验证CSE1的权限，判断CSE1是否具有指示远程CSE创建资源的权限，若有权限，远程CSE则创建资源，并向CSE1发送指示资源创建成功的响应消息，CSE1接收到指示资源创建成功的响应消息后，更新资源的属性“通告到”，即将远程CSE的标识或地址添加到属性“通告到”中。
