Example Embodiment

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0030] At present, the architecture of the 5G core network is a service-based architecture. The network function software is integrated through an open application programming interface (API) to improve the overall agility and flexibility of application development. The NRF in the core network architecture supports network function service registration, status monitoring, etc., to realize automatic management, selection and scalability of network...

Abstract

The invention discloses a method and device for determining the state of a network element. The method comprises the steps: receiving a request message sent by the network element, wherein the requestmessage comprises at least one of a registration request message, a subscription request message, an update service request message and a notification confirmation request message; if the request message is not received within the set time interval, sending the request message; when the number of times that the request message is not received within the set time interval is greater than or equalto the set threshold value, determining that the network element state is a lost state. According to the invention, by setting the time interval and the number of times, the network element can be prevented from sending a large number of messages, and the signaling load of the network element is reduced, thereby avoiding the generation of signaling storms.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a method and device for determining the state of a network element. Background technique [0002] In recent years, with the development of communication technology, the development and changes of the core network architecture are becoming more and more rapid. [0003] In the service-based fifth-generation mobile communication technology (5th-Generation, 5G) core network architecture, the network repository function (network repository function, NRF) is used as the network function (network function, NF) in the core network, and the NF can periodically When the NRF does not receive the registration request message of the NF for several consecutive cycles, it determines that the NF is in a disconnected state. However, due to the large number of NFs, the registration request message is frequently sent to the NRF. This makes the signaling load of the NRF relatively la...
