AI Technical Summary

Technical Problem

In the prior art, the base station needs to maintain a communication link between the backup equipment, which increases the resource overhead of the base station.

Method used

The base station sends an S1 link establishment request to the first core network device and the second core network device, and after receiving the response message, it uses the main device to process the service. If the main device fails, the S1 link establishment request is periodically sent to the backup device, and the S1 link is not established until the backup device changes to the main device.

Benefits of technology

It reduces the resource overhead of base station maintenance equipment communication links, and solves the problem that base stations cannot obtain the load weight parameters of core network equipment.

Abstract

The present application provides a connection method and device between a base station and a core network device. The method includes: the base station sends a first S1 link establishment request to a first core network device and a second core network device respectively, receives a first S1 link establishment response message sent by the first core network device, and uses the first core network device to process services; receives a first S1 link establishment failure message sent by the second core network device, and periodically sends a second S1 link establishment request to the second core network device until a second S1 link establishment response message sent by the second core network device is received, and uses the second core network device to process services. The base station does not need to maintain the S1 link between the backup device, which reduces the resource overhead of the base station.
