Information processing method for machine-to-machine/man (M2M) application, common services entity (CSE) and application entity (AE)

An information processing method for a Machine-to-Machine/Man (M2M) application, applied to a second Common Services Entity (CSE) and comprising:

• receiving a resource updating request sent when a first CSE determines that a resource requested to be created by an Application Entity (AE) has yet not been created in the first CSE, wherein the resource updating request contains a CSE Identifier (ID) of the first CSE and an AE ID;
• querying whether a CSE ID corresponding to a resource requested to be updated in the resource updating request is the CSE ID of the first CSE or not;
• and
• when the CSE ID corresponding to the resource requested to be updated in the resource updating request is the CSE ID of the first CSE, performing resource updating responsive to the resource updating request and sending a second response message indicating an operation success to the first CSE;
• when the CSE ID corresponding to the resource requested to be updated in the resource updating request is not the CSE ID of the first CSE, giving no response to the resource updating request and sending the second response message indicating an operation failure to the first CSE, or changing the CSE ID corresponding to the resource requested to be updated in the resource updating request into the CSE ID of the first CSE, performing resource updating responsive to the resource updating request and sending the second response message indicating an operation success to the first CSE.

A Common Services Entity (CSE), the CSE being a first CSE and comprising:

• a first receiving unit, configured to receive a resource creation request sent by an Application Entity (AE);
• a first judgment unit, configured to judge whether the resource creation request contains an AE Identifier (ID) of the AE or not;
• a second judgment unit, configured to, when the resource creation request contains the AE ID of the AE, judge whether a resource requested to be created in the resource creation request has been created or not based on the AE ID;
• and
• a first sending unit, configured to, in a case where the resource requested to be created in the resource creation request has been created, send a first response message indicating an operation failure to the AE;
• wherein the first sending unit is further configured to, in a case where the resource requested to be created in the resource creation request has yet not been created, send a resource updating request containing a CSE ID of the first CSE and the AE ID to a second CSE;
• and
• the first receiving unit is further configured to receive a second response message sent by the second CSE based on the AE ID and the CSE ID,
• wherein when a CSE ID corresponding to a resource requested to be updated in the resource updating request is the same as the CSE ID of the first CSE, the second response message is a response message indicating an operation success;
• when the CSE ID corresponding to the resource requested to be updated in the resource updating request is different from the CSE ID of the first CSE, the second response message is a response message indicating an operation failure, and the first sending unit is further configured to send the first response message indicating the operation failure to the AE;
• or, the second response message is a response message indicating an operation success which is sent after the second CSE changes the CSE ID corresponding to the resource requested to be updated in the resource updating request into the CSE ID of the first CSE, and the first sending unit is further configured to send a first response message indicating an operation success to the AE.

A Common Services Entity (CSE), the CSE being a second CSE and comprising:

• a second receiving unit, configured to receive a resource updating request sent when a first CSE determines that a resource requested to be created by an Application Entity (AE) has yet not been created in the first CSE, wherein the resource updating request contains a CSE Identifier (ID) of the first CSE and an AE ID;
• a query unit, configured to query whether a CSE ID corresponding to a resource requested to be updated in the resource updating request is the CSE ID of the first CSE or not;
• and
• a second sending unit, configured to, when the CSE ID corresponding to the resource requested to be updated in the resource updating request is the CSE ID of the first CSE, perform resource updating responsive to the resource updating request and send a second response message indicating an operation success to the first CSE;
• wherein
• the second sending unit is further configured to, when the CSE ID corresponding to the resource requested to be updated in the resource updating request is not the CSE ID of the first CSE, give no response to the resource updating request and send the second response message indicating an operation failure to the first CSE;
• or,
• the second sending unit is further configured to, when the CSE ID corresponding to the resource requested to be updated in the resource updating request is not the CSE ID of the first CSE, change the CSE ID corresponding to the resource requested to be updated in the resource updating request into the CSE ID of the first CSE, perform resource updating responsive to the resource updating request and send the second response message indicating an operation success to the first CSE.
