An event notification method and server

Abstract

Embodiments of the present invention provide an event notification method and server, which relate to the field of communication technology and can solve the problem in the prior art that subscribers cannot meet diverse subscription requirements because subscription conditions are simply superimposed on a limited number of atomic conditions. The specific solution is: the server determines whether the updated resource of the publisher satisfies the subscription condition, the subscription condition includes a composite subscription condition, and the composite subscription condition includes at least one first atomic condition, the first atomic condition is the first resource identifier, the first resource attribute Or the condition corresponding to the data content of the resource instance, the first atomic condition in the composite subscription condition is combined through a logical relationship, the logical relationship includes "and", "or" or "not"; if the updated publisher's If the resource meets the subscription condition, the updated event corresponding to the resource of the publisher is notified to the address of the subscriber corresponding to the subscription condition. The embodiment of the present invention is used for event notification.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular, to an event notification method and server. Background technique [0002] The first-generation machine-to-machine (one Machine to Machine, oneM2M) standard is a standard specification for the combination of machine-to-machine communication and the Internet of Things. In the oneM2M standard, a common service entity (common service entity, CSE) represents a series of common service function (common service function, CSF) instances, wherein each CSF has corresponding resource representation and implementation. In the process of publishing and subscribing, the proxy server will notify the notification address (notificationURI) of events that meet the needs of the subscribers according to the subscription conditions stored in the attribute of the event notification rule (eventNotificationCriteria) in the Subscription resource corresponding to each su...
