Problems solved by technology

However, it is found in the prior art that the terminal switches from a cell with better communication quality to another cell with poorer communication quality, or there are unnecessary handovers such as frequent back and forth handovers (ie ping-pong handovers).

example 1

[0163] Such as Figure 7 As shown, this example provides a cell handover method, including:

[0164] Step 0: According to the network planning, configure the neighboring cell list, measurement parameters and handover parameters of the distributed antenna system, and configure the list of allowed handover target cells of each remote unit. The allowed handover target cell list here may be one of the aforementioned handover indication parameters.

[0165] Step 1: A terminal m accesses the distributed antenna system, and triggers handover event measurement and reporting due to location movement, and meets the handover threshold;

[0166] Step 2: The centralized unit demodulates the uplink SRS signal of the terminal m received by each remote unit, and determines that the remote unit n receiving the strongest uplink SRS signal strength is the access remote unit of the terminal m at this time;

[0167] Step 3: The centralized unit queries the allowed switching target cell list desc...

example 2

[0171] This example provides several examples of handover indication parameters based on the cell handover method in Example 1.

[0172] In the above step 0, only the list of whether each remote unit is allowed to be handed over is given, and an example of an implementable form of the allowed handover target cell list can be shown in Table 1:

[0173] Table 1. Example of a list of allowed handover target cells

[0174]

[0175] Wherein, the list of allowed handover target cells must be included in the neighbor cell table of the distributed antenna system.

[0176] In the above step 0, only the list of whether each remote unit is allowed to be handed over is given, and an example of an implementable list form of the allowed handover target cell can be shown in Table 2:

[0177] Table 2. Whether the remote unit is allowed to switch the list

[0178] Remote unit number Whether to allow switching 1 yes 2 no … … N yes

Abstract

The embodiment of the invention discloses a cell switching method, a communication device and a storage medium. The cell handover method includes: determining the remote unit currently accessed by the terminal; when the handover condition is met, querying the configuration parameters of the remote unit, wherein the configuration parameters at least include: a handover indication parameter; the handover indication Parameters, at least used to determine whether to allow the terminal to switch to a neighboring cell; the neighboring cell is a cell adjacent to the coverage area of ​​the corresponding remote area; according to the handover indication parameter, determine whether to allow the terminal to hand over the cell and / or Or the target cell that allows handover.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a cell switching method, communication equipment and a storage medium. Background technique [0002] There is a kind of distributed pico base station (Picocell) in the field of wireless communication. [0003] Such as figure 1 As shown, the distributed pico base station includes: N remote units, and the N remote units are connected to a centralized unit through one or more converging units. Said N is an integer not less than 2 such as 2 or 3. Different remote units cover different areas, but the multiple areas covered by the N remote units belong to the same logical cell. [0004] exist figure 1 Among them, the neighboring cells of the serving cell of terminal 1, terminal 2 to terminal M include: neighboring cell A and neighboring cell B. The terminal can switch between the serving cell and neighboring cell A and neighboring cell B. In the prior art, the termin...
