Problems solved by technology

[0015] The present invention is proposed in view of the problem that the relevant technology does not distinguish whether the candidate cell supports VAMOS, which may increase the network load of the target cell and cause a decrease in network quality. Therefore, the main purpose of the present invention is to provide a cell switching scheme, to address at least one of the above

example 1

[0056] Figure 4 is a flow chart of the method according to Example 1 of the embodiment of the present invention. Such as Figure 4 As shown, the method includes the following steps S402 to S406:

[0057] Step S402, when performing cell handover, the BSC acquires cell information of one or more candidate cells that meet the handover trigger condition, wherein the cell information includes an identifier for indicating whether the candidate cell corresponding to the cell information supports VAMOS.

[0058] In step S404, the BSC divides the candidate cells into two handover groups, Class A and Class B, according to the obtained cell identifiers, and sets the order selection priorities of different classes for the candidate cells in the two groups respectively. Among them, Class A includes all candidate cells that support VAMOS, and the Class B handover family includes all candidate cells that do not support VAMOS. The priorities of Class A and Class B are set according to app...

example 2

[0062] When the number of idle channels of a cell supporting VAMOS is greater than or equal to the number of idle channels of a cell not supporting VAMOS, the terminal supporting VAMOS is preferentially handed over to a candidate cell supporting VAMOS. Figure 5 It is the method flowchart of Example 2 according to the embodiment of the present invention, such as Figure 5 As shown, the method includes the following steps S502 to S510:

[0063] Step S502, when performing cell handover, the BSC divides all candidate cells that meet the handover conditions into two handover families, Class A and Class B, according to the obtained cell IDs during the process of sorting candidate cells, Class A includes all candidate cells that support VAMOS , Class B includes all candidate cells that do not support VAMOS.

[0064] Step S504: Set the family priority. The BSC defines the priority of a candidate cell supporting VAMOS (that is, Class A) as 1, and defines the priority of a candidate ...

example 3

[0072] In the case that the number of idle channels supporting VAMOS cells is smaller than the number of idle channels of cells not supporting VAMOS, it is considered that the terminal supporting VAMOS is handed over to a candidate cell not supporting VAMOS. Figure 6 It is a flow chart of the method according to Example 3 of the embodiment of the present invention, such as Figure 6 As shown, the method includes the following steps S602 to S610:

[0073] Step S602, during cell handover, during the process of sorting candidate cells, the BSC divides all candidate cells that meet the handover conditions into two handover families, Class A and Class B, according to the acquired cell identifiers, Class A includes all candidate cells that support VAMOS, Class B includes all candidate cells that do not support VAMOS.

[0074] Step S604: Set the family priority. The BSC defines the priority of Class A as 0, and the priority of Class B as 1. The priority 1 of a candidate cell that ...

Abstract

The invention discloses a cell switching method and a cell switching device. The cell switching method comprises the following steps: a network side obtains cell information of one or a plurality of candidate cells when performing cell switching, wherein the cell information includes identifications for indicating whether the candidate cells corresponding to the cell information support VAMOS or not; and the network side determines a target cell for switching in one or a plurality of candidate cells according to the identifications. The invention optimizes the network resource and improves the frequency spectrum utilization ratio.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a cell switching method and device. Background technique [0002] In the wireless communication network, due to the movement of the terminal location, the interference of the surrounding environment, and the change of the wireless environment, etc., the communication quality of the terminal will be reduced, thus easily causing call drop. Since the wireless communication network is composed of multiple service cells, in this case, the service can be switched to the cell with good communication quality through the handover process, so as to ensure the normal progress of the communication service and improve the network quality. [0003] The so-called handover refers to when a mobile station (MS for short), which can also be called a terminal, moves from one base station coverage area to another base station coverage area during a call, or when a call is caused by external interfe...
