Problems solved by technology

[0004] In the process of communication between two devices using M2M services, if one device supports the CoAP protocol, while the other device supports other application layer protocols, such as: SIP (Session Initial Protocol, Session Initiation Protocol) or HTTP (Hyper Text Transfer Protocol, hypertext transfer protocol), etc., then in the prior art it is impossible to complete the message intercommunication between the two devices

Embodiment 1

[0049] see figure 2 , this embodiment provides a method for M2M service message delivery for the situation that the CoAP terminal first initiates a request message, and finally realizes the message intercommunication between the CoAP terminal and the Internet server. The method specifically includes the following steps:

[0050]S101. The CoAP terminal sends a CoAP request message to the M2M service gateway. The request message is a CoAP POST message (CoAP sending message), and the relevant header fields of the CoAP POST message are as follows:

[0051] Ver: 1

[0052] T: 0

[0053] OC: 1

[0054] CODE: 2 = POST

[0055] Transaction ID: 1234

[0056] Option Delta: 9 = URI

[0057] Length: 12

[0058] Option Value: www.m2m.com / weather

[0059] Payloads:

[0060] Data ID = Temperature;

[0061] Content=35

[0062] Wherein, the part before the Payloads in the CoAP request message is the CoAP message control parameter, and the part after the Payloads is the content of th...

Embodiment 2

[0081] see image 3 , this embodiment provides a method for M2M service message delivery for the situation that the CoAP terminal first initiates a request message, and finally realizes the message intercommunication between the CoAP terminal and the SIP client. The method specifically includes the following steps:

[0082] S201. The CoAP terminal sends a CoAP request message to the M2M service gateway. The request message is a CoAPPOST message, and the relevant header fields of the CoAP POST message are as follows:

[0083] Ver: 1

[0084] T: 0

[0085] OC: 1

[0086] CODE: 2 = POST

[0087] Transaction ID: 1234

[0088] Option Delta: 9 = URI

[0089] Length: 26

[0090] Option Value: www.m2m.com / delivering? Receiver=SIP:client@example.com

[0091] Payloads:

[0092] Data ID = Temperature;

[0093] Content=35

[0094] S202. After receiving the CoAP POST message in S201, the M2M service gateway performs route selection according to the Receiver identification parame...

Embodiment 3

[0123] see Figure 4 , this embodiment provides another M2M service message delivery method for the situation that the CoAP terminal first initiates a request message, and finally realizes the message intercommunication between the CoAP terminal and the Internet server. The method specifically includes the following steps:

[0124]S301. The CoAP terminal sends a CoAP request message to the M2M service gateway. The request message is a CoAP POST message, and the relevant header fields of the CoAP POST message are as follows:

[0125] Ver: 1

[0126] T: 0

[0127] OC: 1

[0128] CODE: 2 = POST

[0129] Transaction ID: 1234

[0130] Option Delta: 9 = URI

[0131] Length: 12

[0132] Option Value: www.m2m.com / weather

[0133] Payloads:

[0134] Data ID = Temperature;

[0135] Content=35

[0136] S302. After the M2M service gateway receives the CoAP POST message in step S301, it performs routing selection according to the M2M network configuration content stored in the ga...

Abstract

The invention discloses a method and device for delivering M2M (machine to machine) service messages, relating to the communication field and being used for realizing message intercommunication of devices for supporting a constrained application protocol (CoAP) and devices for supporting other application layer protocols in an M2M service. The method comprises the following steps: receiving a first protocol message sent by a sender; converting the first protocol message into a second protocol message; and sending the second protocol message to a receiver, wherein one of the first protocol message and the second protocol message is a CoAP message, and the other one is a protocol bearing message. The method and device disclosed by the invention can be applied to mutual conversion between the CoAP message and the protocol-bearing message.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for M2M service message delivery. Background technique [0002] The Internet of Things (Internet of Things or M2M) is to connect any object with the Internet through radio frequency identification equipment, infrared sensors, global positioning systems, laser scanners and other information sensing equipment according to agreed protocols for information exchange and communication. , to realize a network of intelligent identification, positioning, tracking, monitoring and management of objects. [0003] At present, major standard organizations in the industry are formulating standard protocols related to the Internet of Things. For example, IETF (Internet Engineering Task Force, Internet Engineering Task Force) has specially established a CoRE (Constrained RESTful Environment, Constrained Representational State Transfer Environment) working group , the group f...
