The middle node (MN) comprises a sending unit for the MN to send topological information about the MN to an infrastructure node (IN) after the IN is registered, the topological information comprising identification information about an application service node (ASN) and an application dedicated node (ADN) which have been registered to the MN; and an indication unit for instructing the IN to store the topological information to enable the IN to forward a machine-to-machine (M2M) service message according to the topological information and identification information about a destination ASN or ADN in the M2M service message. In the solution, the M2M service message is not required to be forwarded to all connected MNs, and only the MN to which the destination ASN or ADN is registered participates in a forwarding process of the M2M service message.

Description

Intermediate node, infrastructure node and M2M service message forwarding method

TECHNICAL FIELD The present invention relates to the field of Internet of Things technologies, and in particular, to an intermediate node (English: Middle Node, referred to as MN), an infrastructure node (English: Infrastructure Node, referred to as: IN), and a machine-to-machine (English: Machine-to -Machine, abbreviation: M2M) Service message forwarding method. Background technique

M2M communication is a networked application and service centered on machine intelligent interaction. By embedding wireless or wired communication modules and application processing logic inside the machine, data communication without manual intervention is realized to meet user monitoring and command. Information needs for scheduling, data collection and measurement.

The system that implements M2M communication is called M2M system. The M2M system has the following possible architectures. The first architecture includes IN, MN, and application service node (English: Application Service Node, ASN). The second architecture includes IN. , MN and Application Dedicated Node (English: Application Dedicated Node, ADN for short), the third architecture includes IN, MN, ASN and ADN. Figure 1 shows the structure of the third architecture. IN can connect multiple MNs. Each MN connects multiple ASNs and/or ADNs. IN can also directly connect multiple ASNs and/or ADNs and INs in ASNs. The M2M service message is forwarded between the ADN and the ASN and the ADN to implement the M2M service.

In the case where the IN is connected to multiple MNs, the IN first sends an M2M service message to each connected MN. After receiving the M2M service message, each MN determines the destination ASN or ADN of the M2M service message, the destination ASN or the ADN. The connected MN forwards the M2M service message to the destination ASN or ADN. It can be seen that in the process of forwarding an M2M service message, the IN needs to forward the M2M service message to all connected MNs. Therefore, each MN needs to participate in the M2M service message forwarding process, which causes serious signaling resources of the M2M system. waste.

The sending unit 21 is configured to send, by the MN, the topology information of the MN to the IN after the IN registration, and the topology information includes the identifier information of the ASN and the ADN that have been registered to the MN.

When an ASN or an ADN is registered to the MN, the MN stores the identification information of the ASN or the ADN to form the topology information of the MN. The identification information of the ASN or the ADN may be an Internet Protocol (English: Internet Protocol, IP address) address. , hardware serial number, and more.

After the MN registers on the IN, the transmission unit 21 can transmit the topology information of the MN to the IN.

The indicating unit 22 is configured to instruct the IN to store the topology information, so that the IN forwards the M2M service message according to the topology information and the identifier information of the destination ASN or the ADN in the M2M service message.

In the M2M system shown in Figure 1, when the M2M service is performed between the ASN or the ADN through the M2M service message, the IN can forward the M2M service message between the two ASNs or ADNs according to the stored topology information and the M2M service message.

In this solution, after the IN is registered, the MN sends its own topology information to the IN, and instructs the IN to store the topology information. Since the topology information includes the identifier information of the ASN and the ADN that have been registered to the MN, when the IN receives the M2M. After the service message, the MN registered by the destination ASN or the ADN can be determined according to the identifier information of the destination ASN or ADN carried in the M2M service message and the saved topology information, and then the M2M service message is forwarded to the determined MN without forwarding to all connections.

Specifically, the foregoing indicating unit 22 is specifically configured to:

Instructs IN to create network topology properties and store topology information in network topology properties.

When the indication unit 22 indicates that the IN stores the topology information of the MN, it may first instruct the IN to create a network topology attribute, and then store the topology information of the MN in the network topology attribute.

The network topology attribute can be an attribute of the resource created by the IN. For example, the resource created by the IN is represented as a <remote (English: remote) CSE> resource, and the network topology attribute can be represented as a topology attribute, and the topology attribute is 々61^16. > Properties under the resource.

Optionally, the indicating unit 22 is further configured to:

If it is detected that the ASN or ADN registered on the MN changes, according to the change of ASN or ADN, IN updates the topology information and sends it to IN, indicating that IN updates the topology information.

The ASN or ADN registered to the MN may change. For example, there may be a new ASN or ADN registered to the MN, or it may have been registered to the ASN or ADN on the MN to register, when these changes occur. The topology information of the MN is changed. Therefore, the indication unit 22 needs to monitor whether the ASN or the ADN on the MN changes, and the topology information of the MN is updated according to the change of the ASN or the ADN, so as to ensure the accuracy of the topology information on the IN. Sexuality, which in turn ensures that the IN correctly forwards M2M service messages.

The MN that is registered by the ASN or the ADN forwards the M2M service message to the found MN, and then the MN further forwards the M2M service message to the destination ASN or the ADN, thereby implementing the forwarding of the M2M service message, since only the M2M service message is sent. It is forwarded to the MN registered by the destination ASN or ADN, so it does not waste the signaling resources of the M2M system.

In this solution, after the IN is registered in the IN, the MN may not send its own topology information to the IN, but store its own topology information, and then send a topology information storage notification to the IN, since the topology information includes the ASN and the ADN registered to the MN. The identification information, when the IN receives the M2M service message, firstly, the topology information of each MN is used to query the identifier information of the destination ASN or ADN carried in the M2M service message, and then determine the MN registered by the destination ASN or ADN, and then The M2M service message is forwarded to the determined MN, and the MN registered by the destination ASN or the ADN is involved in the forwarding process of the M2M service message. The signaling resource of the M2M system is saved compared with the prior art.

When storing the topology information of the MN, the storage unit 51 may first create a network topology attribute and then store the topology information of the MN in the network topology attribute.

The network topology attribute may be an attribute under the resource created by the MN, for example, the resource created by the MN is represented as

<remoteCSE> resource, network topology attribute can be expressed as topology attribute, topology attribute is < 1^16. 8 £> Properties under the resource.

The topology information update notification is finally sent by the sending unit 52 to the IN according to the notification of the processing unit 54 to notify the IN that the topology information on the MN has been updated.

Specifically, the foregoing processing unit 54 is specifically configured to:

When the changes to the ASN or ADN registered to the MN are different, the topology information of the MN is updated differently.
