Problems solved by technology

[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. The signaling load of NRF is relatively large, leading to the generation of signaling storms

Embodiment Construction

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0030] At present, the architecture of the 5G core network is a service-based architecture, and the network function software is integrated through an open application programming interface (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., and realizes automatic manage...

Abstract

The invention discloses a method and device for determining the state of a network element, which receives a request message sent by the network element, and the request message includes 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, and the number of times the request message is not received within the set time interval is greater than or equal to the set threshold, it is determined that the state of the network element is disconnected. By setting the time interval and The number of times can prevent the network element from sending a large number of messages, reduce the signaling load of the network element, and thus avoid the occurrence 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...
