Embodiment 1

[0023] An embodiment of the present invention provides a handover method, which is applied to a source base station, such as figure 1 shown, including:

[0024] Step 101: receiving a handover request from a target terminal device, the handover request at least including a signal measurement report of the target terminal device;

[0025] Step 102: Obtain a frequency offset value corresponding to the target terminal device, where the frequency offset value is used to represent the frequency offset of the uplink signal of the target terminal device at the current moment;

[0026] Step 103: Based on the signal measurement report of the target terminal device and the frequency offset value corresponding to the target terminal device, determine whether to perform a handover operation on the target terminal device.

[0027] Here, the source base station can be understood as a base station applied to a private network, especially a base station applied to a high-speed rail private ne...

Embodiment 2

[0047] On the basis of the above embodiments, this embodiment focuses on how to determine the frequency offset threshold, which may include the following two methods:

[0048] method one,

[0049] Obtain historical switching information of M terminal devices managed by itself; wherein, M is an integer;

[0050] Based on the historical handover information of the M terminal equipments, select N terminal equipments whose handover times between the source base station and the target base station are greater than 1; where N is an integer less than or equal to M;

[0051] Based on the historical handover information of the N terminal devices, acquiring the corresponding frequency offset values ​​of the N terminal devices each time the handover is determined;

[0052] Determine the frequency offset threshold corresponding to the source base station based on the frequency offset values ​​corresponding to the N terminal devices each time handover is determined.

[0053] Wherein, the...

Embodiment 3

[0073] An embodiment of the present invention provides a base station, such as Figure 5 As shown, the base station includes:

[0074] The receiving unit 51 is configured to receive a handover request sent by the target terminal device, where the handover request includes at least a signal measurement report of the target terminal device;

[0075] An information extraction unit 52, configured to acquire a frequency offset value corresponding to the target terminal device, where the frequency offset value is used to represent the frequency offset of the uplink signal of the target terminal device at the current moment;

[0076] The processing unit 53 is configured to determine whether to perform a handover operation on the target terminal device based on the signal measurement report of the target terminal device and the frequency offset value corresponding to the target terminal device.

[0077] Here, the source base station can be understood as a base station applied to a pr...

Abstract

The invention discloses a switching method and a base station. The method comprises the following steps: receiving a switching request sent by a target terminal device, wherein the switching request at least comprises a signal measurement report of the target terminal device; obtaining a frequency offset value corresponding to the target terminal device, wherein the frequency offset value is usedfor characterizing the frequency offset of an uplink signal of the target terminal device at the current moment; and determining whether to execute a switching operation on the target terminal devicebased on the signal measurement report of the target terminal device and the frequency offset value corresponding to the target terminal device.

Description

technical field [0001] The invention relates to signal processing technology in the communication field, in particular to a switching method and a base station. Background technique [0002] At present, the high-speed rail private network adopts the method of radiating signals from surrounding iron towers to the carriages. The high-speed rail carriages are closed and the penetration loss is high. Therefore, high-gain narrow-beam antenna products are generally used in high-speed rail private networks, and the antenna gain can reach 20dBi (this value is the value of the F frequency band, and 21dBi for the D frequency band). However, in the solutions provided in the prior art, in the scenario where a terminal device moving at high speed performs base station handover, it cannot be guaranteed to avoid multiple handovers between cells, and user experience cannot be guaranteed. Contents of the invention [0003] In view of this, the object of the present invention is to provide...
