Classification: CPC H | IPC H

Claim 12:
13. A network side device of an Internet of Vehicle (IoV) system, comprising:
a resource creation circuitry configured to create a subscription resource, the subscription resource comprising an event notification rule;
a determination circuitry configured to determine whether subscribed data meets the event notification rule; and
an event generation circuitry configured to, when the determination circuitry determines that the subscribed data meets the event notification rule, generate an event notification;
wherein the subscription resource further comprises a scenario rule, wherein the scenario rule comprises an environment rule and a road rule; wherein the environment rule comprises at least one of a temperature attribute, a humidity attribute, an amount-of-rain attribute and a sunlight intensity attribute; wherein the road rule comprises a vehicle information attribute and a traffic information attribute;
wherein the network side device further comprises a scenario determination circuitry configured to determine a first scenario where an IoV device in a vehicle is located in accordance with the scenario rule and determine a first event notification rule in accordance with the first scenario, and the determination circuitry is further configured to determine whether the subscribed data meets the first event notification rule in accordance with the first event notification rule; wherein first event notification rules in different first scenarios have different contents;
wherein the first event notification rule comprises a change rate event notification rule, and the change rate event notification rule comprises whether a change rate of content information about a received Nth content instance relative to content information about at least one content instance in a first content instance to an (N−1)th content instance meets a predetermined threshold, where N is a variable and a natural number not smaller than 2, wherein different first scenarios corresponds to different predetermined thresholds, respectively;
wherein the determination circuitry is further configured to determine whether the change rate of the content information about the received Nth content instance relative to the content information about the at least one content instance in the first content instance to the (N−1)th content instance meets the predetermined threshold, and when the change rate of the content information about the received Nth content instance relative to the content information about the at least one content instance in the first content instance to the (N−1)th content instance meets the predetermined threshold, determine that the subscribed data meets the event notification rule.
