Switching method, base station and communication system

Abstract

An embodiment of the invention provides a switching method. The method comprises the step that a source base station determines to switch user equipment to a target base station and then sends a switch request message to a source core network device, wherein the switching request message comprises identification information of a target core network device, and the switching request message is usedfor indicating the source core network device and the target core network device to perform core network migration. The switching method can be applied to a target base station and supports scenes ofthe source core network and the target core network; the switching request message carries the identification information of the target core network device, so that the source core network device canidentify the target core network device accurately so as to finish core network migration and improve switching efficiency.

Description

technical field [0001] Embodiments of the present invention relate to wireless communication technologies, and in particular to a handover method, a base station and a communication system. Background technique [0002] With the continuous improvement of user requirements, research on new radio access technology (new radio access technology, New RAT or NR or NRAT) is getting more and more in-depth. Compared with existing wireless communication systems, communication systems using new radio access technology (New RAT or NR or NRAT) can provide shorter delays, greater bandwidth, and support a large number of connections. To meet the growing demand for mobile communications. [0003] Based on the base station equipment in the Long Term Evolution (LTE) access network, that is, the evolved Node B (evolved NodeB, eNB), combined with New RAT, an evolved LTE base station (evolution of eNB, eLTE eNB) is produced. . The eLTE eNB is the base station equipment in the new radio access...

AI Technical Summary

Problems solved by technology

However, in the process of switching from the core network corresponding to the existing radio access network to the core network corresponding to the new radio access network, the source core network cannot accurately find the target core network according to the above tracking area identification, and thus cannot complete the core network migration process
