Embodiment 2

[0142] The embodiment of the present invention also provides a switching system of a base station. The system is used to implement the above-mentioned embodiments and preferred implementation modes, and what has been described will not be repeated. As used below, the term "module" may be a combination of software and / or hardware that realizes a predetermined function. Although the devices described in the following embodiments are preferably implemented in software, implementations in hardware, or a combination of software and hardware are also possible and contemplated.

[0143] The handover method of the base station in the embodiment of the present application can run on Figure 8 On the network architecture shown, Figure 8 is a schematic diagram of a handover system of a base station according to an embodiment of the present invention. Such as Figure 8 As shown, the system may include: a first AMF and a second AMF.

Embodiment 3

[0156] The embodiment of the invention also provides a storage medium. Optionally, in this embodiment, the above-mentioned storage medium may be configured to store program codes for performing the following steps:

[0157] S1. Instruct the first access and mobility management function module, the first AMF, to receive handover request information sent by the first base station, where the handover request information is used to request handover of the user equipment from the first base station to the second base station;

[0158] S2. In the case that the user equipment does not need to perform cross-AMF handover, instruct the first AMF to send a handover preparation request to the second base station to request target resources for the user equipment, and the handover preparation request carries handover request information and session information of the user equipment, The cross-AMF switching is used to indicate that the AMF of the user equipment is changed from the first AMF...

Abstract

The invention provides a base station switching method and system. The method comprises the following steps that: a first access and mobility control function (AMF) module receives switching request information transmitted by a first base station, wherein the switching request information is used for requesting switching of user equipment from the first base station to a second base station; underthe situation that the user equipment does not need to perform cross-AMF switching, the first AMF sends a switching preparation request to the second base station to request a target resource for theuser equipment, wherein the cross-AMF switching is used for indicating that an AMF of the user equipment is changed from the first AMF to a second AMF; and under the situation that the user equipmentneeds to perform the cross-AMF switching, the first AMF transmits the switching request information to the second AMF, and the second AMF sends a switching preparation request to the second base station in order to request a target resource for the user equipment. Through adoption of the base station switching method and system, the technical problem that a target side cannot reserve resources for a user terminal in the prior art is solved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a base station handover method and system. Background technique [0002] 3GPP (3rd Generation Partnership Project, Third Generation Partnership Project) has been discussing the next generation communication system (NextGen System) since R14. The next generation communication system can support eMBB (Evolved Mobile Broadband, evolved mobile broadband), mMTC (Massive Machine Type Communication, ultra-large connection machine communication), uMTC (Ultra Reliable Machine Type Communication, ultra-reliable machine communication) three business types, these three business types have different network characteristics. figure 1 It shows the next generation mobile communication network architecture, where the functions of each network element are as follows: [0003] The terminal UE (User Equipment) mainly accesses the network and obtains services through the next-generation wireless a...
