This message may indicate identifiers of these resources, event notification criteria for each individual resource, and define cross-resource notification criteria, such as time window type and time window size. The resource host issues cross-resource notifications to the subscriber or its designated notification targets when expected changes on the target resources occur within a time window. ## Claims ### Claim at position 1 1-20. (canceled) ### Claim 21 An apparatus for cross-resource subscription, the apparatus comprising: a processor; and a memory coupled with the processor, the memory comprising executable instructions that when executed by the processor cause the processor to effectuate operations comprising: receiving a message for a cross-resource subscription, wherein the message is indicative of a request, by a remote device, for a subscription, wherein the subscription is for the remote device to be notified of a change of a plurality of target resources that meet a criteria within a window of time; based on the message, determining that the remote device has privilege to create the cross-resource subscription; and based on having the privilege to create the cross-resource subscription, generating a local subscription resource for the cross-resource subscription. ### Claim 22 (depends on 21) The apparatus of claim 21, wherein the message comprises a list of event notification criteria for the plurality of target resources. ### Claim 23 (depends on 21) The apparatus of claim 21, wherein the message comprises a number of the plurality of target resources in which a notification is expected to be received when the criteria are met. ### Claim 24 (depends on 21) The apparatus of claim 21, wherein the message comprises an indication of a type of the window of time. ### Claim 25 (depends on 21) The apparatus of claim 21, wherein the message comprises an indication of a type of the window of time, wherein the type of window of time comprises a sliding time window. ### Claim 26 (depends on 21) The apparatus of claim 21, the operations further comprising providing instructions to send a response message that comprises an indication of approval of cross-resource subscription. ### Claim 27 (depends on 21) The apparatus of claim 21, wherein at least one resource of the target resources is located on the remote device. ### Claim 28 (depends on 21) The apparatus of claim 21, the operations further comprising providing a request for a subscription to a first resource of the plurality of target resources, wherein the request comprises a criterion of the criteria. ### Claim 29 (depends on 28) The apparatus of claim 28, the operations further comprising: receiving a notification that the criterion of the criteria was met; determining that the criteria is met based on receiving the notification; and notifying the remote device based on the determining that the criteria is met. ### Claim 30 (depends on 21) The apparatus of claim 21, wherein the apparatus comprises a common service entity. ### Claim 31 A method for cross-resource subscription, the method comprising: receiving, by a machine-to-machine entity, a message for a cross-resource subscription, wherein the message is indicative of a request, by a remote device, for a subscription, wherein the subscription is for the remote device to be notified of a change of a plurality of target resources that meet a criteria within a window of time; based on the message, determining, by the machine-to-machine entity, that the remote device has privilege to create the cross-resource subscription; and based on having the privilege to create the cross-resource subscription, generating, by the machine-to-machine entity, a local subscription resource for the cross-resource subscription. ### Claim 32 (depends on 31) The method of claim 31, further comprising publishing an indication of information of the local subscription resource to a display. ### Claim 33 (depends on 31) The method of claim 31, further comprising publishing parameters of the message for cross-resource subscription to a display. ### Claim 34 (depends on 31) The method of claim 31, further comprising publishing, to a display, events that meet criteria within a graphical representation of the window of time. ### Claim 35 (depends on 31) The method of claim 31, wherein the message comprises list of event notification criteria for the plurality of target resources. ### Claim 36 (depends on 31) The method of claim 31, wherein the message comprises a number of the plurality of target resources in which notifications is expected to be received when the criteria are met. ### Claim 37 (depends on 31) The method of claim 31, wherein the message comprises an indication of a type of the window of time. ### Claim 38 (depends on 31) The method of claim 31, further comprising providing instructions to send a response message that comprises an indication of approval of cross-resource subscription. ### Claim 39 (depends on 31) The method of claim 31, wherein at least one resource of the target resources is located on the remote device. ### Claim 40 (depends on 31) The method of claim 31, further comprising providing a request for a subscription to a first resource of the plurality of target resources, wherein the request comprises a criterion of the criteria.
