Event notification method and server

Abstract

Embodiments of the invention provide an event notification method and a server, relate to the technical field of communication, and can solve a problem that various subscription requirements of a subscriber cannot be met due to the fact that a subscription condition is only simple superposition of limited atomic conditions in the prior art. A specific scheme is as follows: the server determines whether an updated resource of a publisher satisfies the subscription condition or not, wherein the subscription condition comprises a composite subscription condition, the composite subscription condition comprises at least one first atomic condition, and the first atomic condition is a condition corresponding to a first resource identifier, a first resource attribute or a data content of a resource instance, the first atomic conditions in the composite subscription condition are combined through a logical relationship, the logical relationship includes "AND", "OR" or "NOT"; and If the updatedresource of the publisher is determined to satisfy the subscription condition, an event corresponding to the updated resource of the publisher is notified to an address of the subscriber correspondingto the subscription condition. The embodiments of the invention are used for carrying out 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...
