Embodiment Construction

[0060] The technical solution in this application will be described below with reference to the accompanying drawings.

[0061] Based on the service architecture defined by 3GPP, such as the 5G system, when a certain network element judges that it is necessary to perform network element cutover, it will send a service deregistration request or a service update request to NRF, and NRF will deregister the status or The update state is notified to all other network elements (ie, subscribing network elements) that have subscribed to the service state of the network element, so as to trigger the subscribing network element to initiate or update a context request to the new side network element.

[0062] Since the NRF does not perceive the number of affected users on each subscribing network element or the reason for initiating network element cutover, it may be unreasonable for the NRF to notify each subscribing network element to register or update the status, resulting in core net...

Abstract

Provided are a method for notifying a service state, a communication system and a communication device, the method comprising: a first network element sending a service de-registration request messageor a service update request message comprising a notification policy to a network element discovery device, so that the network element discovery device can send the service state notification message (i.e., the de-registration state or the update state) is sent to the plurality of subscription network elements subscribing the service state of the first network element according to the notification policy in a relatively reasonable manner, so that the problems of overweight signaling load of a core network and fluctuation of network performance are solved.

Description

technical field [0001] The present application relates to the field of communication, and more particularly, to a method for notifying service status, a communication system and a communication device. Background technique [0002] Currently, in the fifth generation (5th generation, 5G) architecture defined by the third generation partner project (the 3rd generation partner project, 3GPP), the interface between network elements of the control plane adopts a service architecture. Based on the service architecture, each control plane network element registers its own address and supported service information with a network repository function (NRF) for third-party network elements to query. When a network element judges that it is necessary to perform network element cutover, it will send a service deregistration request message or a service update request message to NRF, and NRF will notify all subscribers of the network element service status of the deregistration status or ...
