The following description describes a new radio (NR) system for example purposes, and NR terms are used in most of the following descriptions, but these technologies can also be applied to applications other than NR system applications, such as the 6th Generation (6G) communication system.

[0031] Figure 1 The following is a schematic diagram of the structure of a wireless communication system applicable to the embodiment of the present application. The wireless communication system includes a terminal 11, a signal amplifier and a network side device 12. The terminal 11 may also be referred to as a terminal device or a user terminal (User Equipment, UE). The terminal 11 may be a mobile phone, a tablet computer (Tablet Personal Computer), a laptop computer (Laptop Computer) or a notebook computer, a personal digital assistant (Personal Digital Assistant, PDA), a handheld computer, a netbook, an ultra-mobile personal computer (ultra-mobile personal computer, UMPC), a mobile Internet device (Mobile Internet Device, MID), a wearable device (WearableDevice) or a vehicle-mounted device (VUE), a pedestrian terminal (PUE) and other terminal side devices. The wearable device includes: a smart watch, a bracelet, a headset, glasses, etc. It should be noted that the specific type of the terminal 11 is not limited in the embodiment of the present application.

[0032] The network side device 12 can be a base station or a core network, wherein the base station can be referred to as a node B, an evolved node B, an access point, a base transceiver station (Base Transceiver Station, BTS), a radio base station, a radio transceiver, a basic service set (Basic Service Set, BSS), an extended service set (Extended Service Set, ESS), a B node, an evolved B node (eNB), a home B node, a home evolved B node, a WLAN access point, a WiFi node, a transmitting and receiving point (Transmitting Receiving Point, TRP) or some other suitable term in the field. As long as the same technical effect is achieved, the base station is not limited to a specific technical vocabulary.

[0033] The signal amplifier may include a terminal module (Mobile Termination, MT) and a radio unit (Radio Unit, RU), wherein the MT is used to establish a connection with a base station (such as an original base station or a target base station), that is, the base station exchanges information with the signal amplifier through the MT, such as configuring the transmission parameters of the signal amplifier, including the on / off of the signal amplifier, the transmission beam on the signal amplifier, etc. The RU is used to establish a signal connection with the UE for signal interaction. In other words, the signal amplifier can be understood as a network node located between the UE and the base station to amplify uplink and downlink signals.

[0034] So, for Figure 1 The wireless communication system shown in FIG. Figure 2 In order to ensure that the signal amplifier can be smoothly and smoothly switched from the original base station to the target base station, the present application provides a switching method, device and network-side equipment. The following further combines the accompanying drawings to describe in detail the technical solution provided by the embodiments of the present application through some embodiments and their application scenarios. It should be understood that, according to different communication scenarios, in the technical solution given by the present application, the original base station and the target base station involved in the switching process can exchange roles. For example, the original base station can be used as the target base station, and the target base station can also be used as the original base station, etc., which is not limited here.

[0035] like Figure 3 As shown, it is a flowchart of a switching method 300 provided by an exemplary embodiment of the present application. The method 300 can be, but is not limited to, executed by the original base station, and can be specifically executed by hardware and / or software installed in the original base station. In this embodiment, the method 300 can at least include the following steps.

[0036] S310, the original base station sends a handover request to the target base station.

[0037] The switching request carries context information of the signal amplifier to inform the target base station of RU capability parameters, current configuration parameters, etc. of the signal amplifier, so that the target base station can determine reconfiguration information for switching the signal amplifier based on the context information of the signal amplifier.

[0038] In this embodiment, the context information of the signal amplifier may include multiple types. For example, the signal amplifier includes Figure 2 or Figure 1 In the case of the MT and RU shown, the context information of the signal amplifier may include the context information of the MT and / or the context information of the RU. Accordingly, in the process of switching the signal amplifier from the original base station to the target base station, the MT and the RU also need to be switched from the original base station to the target base station at the same time. For example, taking the RU as an example, it is necessary to switch from forwarding the downlink signal sent by the original base station and the uplink signal forwarded to the original base station to forwarding the downlink signal sent by the target base station and the uplink signal forwarded to the target base station.

[0039] In one implementation, the handover request may be triggered by a measurement report sent by the original base station based on the signal amplifier. In addition, in addition to the context information of the signal amplifier, the handover request may also carry the context information of the terminal, so as to send a handover request to the target base station for both the signal amplifier and the terminal.

[0040] S320: The original base station receives a handover response sent by the target base station.

[0041] The handover response carries first reconfiguration information determined by the target base station based on the context information of the signal amplifier, such as working parameter configuration information of the RU, working parameter configuration information of the MT, and the like.

[0042] In one implementation, after receiving the switching request sent by the original base station, the target base station can determine whether to allow the signal amplifier to access, and if the signal amplifier is allowed to access, the target base station further determines the first reconfiguration information corresponding to the context information of the signal amplifier based on the context information of the signal amplifier carried in the switching request and in combination with its own configuration parameters, and sends it to the original base station through a switching response.

[0043] S330: The original base station sends a switching command to the signal amplifier.

[0044] The handover command carries second reconfiguration information determined by the original base station based on the first reconfiguration information. In this embodiment, the second reconfiguration information may be the same as the first reconfiguration information, or may include at least part of the first reconfiguration information, which is not limited here.

[0045] In one implementation, after receiving the switching command, the signal amplifier may switch from the original base station to the target base station according to the second reconfiguration information.

[0046] In this embodiment, when it is necessary to switch the signal amplifier from the original base station to the target base station, the original base station can send a switching request carrying the context information of the signal amplifier to the target base station, so that the target base station can feed back the reconfiguration information generated based on the context information of the signal amplifier to the original base station, and the original base station sends a switching command to the signal amplifier based on the reconfiguration information, so that the signal amplifier is switched from the original base station to the target base station. Thus, a set of switching processes can be provided for the switching of the signal amplifier, thereby ensuring that the signal amplifier is switched from the original base station to the target base station smoothly.

[0047] like Figure 4 As shown, it is a flowchart of a switching method 400 provided by an exemplary embodiment of the present application.
