Machine-To-Machine (M2M) Interface Procedures For Announce and De-Announce of Resources

Abstract

Systems, methods, and instrumentalities are disclosed to propagate announcement and de-announcement of a resource across one or more networks. A first entity, which may be a hosting service capability layer (SCL), may receive a request from an issuer to announce a resource. The first entity may create a representation of the resource. The representation may be referred to as an announced resource. The first entity may send an announce resource request to a second entity (e.g., an announced-to SCL), which may be registered with the first entity. The announce resource request may be sent over an mid interface. The first entity may receive a first response from the second entity over the mid interface indicating that the second entity created the announced resource.

1 - 14 . (canceled) 
     
     
         15 . A method for creation of an announced resource, the method comprising:
 receiving, by a first entity, a request from an issuer to announce a resource to one or more service capability layers;   creating an announced resource on the first entity, wherein the announced resource comprises a search string and an identifier;   sending, by the first entity, an announce resource request to a second entity over an mId interface; and   receiving, in response to the announce resource request, a first response from the second entity over the mId interface indicating that the second entity created the announced resource.   
     
     
         16 . The method of  claim 15 , wherein the issuer is one of a service capability layer or an application. 
     
     
         17 . The method of  claim 15 , wherein the second entity has registered with the first entity. 
     
     
         18 . The method of  claim 15 , wherein receiving the request to announce the resource comprises receiving an attribute, wherein the attribute is changeable to indicate the request. 
     
     
         19 . The method of  claim 15 , further comprising determining that the second entity is an entity to announce to based on accessibility of the resource. 
     
     
         20 . The method of  claim 17 , wherein the first entity posts the announced resource to the second entity under a known URI. 
     
     
         21 . The method of  claim 15 , further comprising sending a second response to the issuer indicating that the second entity created the announced resource. 
     
     
         22 . A first entity comprising:
 a processor configured to:   receive a request from an issuer to announce a resource to one or more service capability layers;   create an announced resource, wherein the announced resource comprises a search string and an identifier;   send an announce resource request to a second entity over an mId interface; and   receive, in response to the announce resource request, a first response from the second entity over the mId interface indicating that the second entity created the announced resource.   
     
     
         23 . The first entity of  claim 22 , wherein the issuer is one of a service capability layer or an application. 
     
     
         24 . The first entity of  claim 22 , wherein the second entity has registered with the first entity. 
     
     
         25 . The first entity of claim  8 , wherein receiving the request to announce the resource comprises receiving an attribute, wherein the attribute is changeable to indicate the request. 
     
     
         26 . The first entity of  claim 22 , wherein the processor is further configured to determine that the second entity is an entity to announce to based on accessibility of the resource. 
     
     
         27 . The first entity of  claim 24 , wherein the first entity posts the announced resource to the second entity under a known URI. 
     
     
         28 . The first entity of  claim 22 , wherein the processor is further configured to send a second response to the issuer indicating that the second entity created the announced resource.
