Problems solved by technology

Once an unusable cell is formed in the field, it cannot be restored by itself, seriously affecting user access
[0008] For available cells, if the following conditions exist: the failure rate of wireless link establishment is high, the proportion of wireless links not restored after establishment is high, and the number of correct RACH packets received by the cell is small, such a cell is actually difficult to access. into

Embodiment Construction

[0047] Below in conjunction with accompanying drawing, the method for self-recovery of no-traffic cell of the present invention is described in further detail:

[0048] figure 1 Shows a self-recovery method for a cell without traffic of the present invention, such as figure 1 As shown, the method includes the following steps:

[0049] By detecting the items in the cell that cause user access difficulties within a certain period of time, it is confirmed whether the cell is a cell with no traffic;

[0050]After confirming that the cell is a cell with no traffic, delete the cell;

[0051] after deleting the cell, re-establishing the cell;

[0052] Among them, the items that cause user access difficulties include the failure ratio of wireless link establishment, the ratio of wireless link recovery, the number of correct RACH packets, the number of repeated deletions of the secondary public control physical channel SCCPCH, and the forward access channel in the cell. FACH, Rando...

Abstract

The invention discloses a telephone traffic-free cell self recovery method and a telephone traffic-free cell self recovery device. The method includes the following steps that: items of a cell which cause user access difficulty in a certain duration are detected, such that whether the cell is a telephone traffic-free cell is determined; after the cell is determined as the telephone traffic-free cell, the cell is deleted; and after the cell is deleted, a cell is re-established. According to the telephone traffic-free cell self recovery method, the items of the cell which cause user access difficulty are detected, such that the cell can be determined as the telephone traffic-free cell, and the telephone traffic-free cell is deleted, and the cell is re-established, and therefore, the problem of unavailability of cells can be solved, and normal user access can be ensured.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, in particular to a method and device for self-recovery of a cell without traffic. Background technique [0002] For the definition of an available cell, the following conditions must be met at the same time: [0003] Condition 1: The cell is not actively powered off, blocked, or powered off, the base station is not in engineering mode, and there are no other alarms that cause the base station to be unavailable. [0004] Condition 2: During system information update, the cell is not barred (BAR) or reserved (RESERVED), and the cell broadcast package is complete; [0005] Condition 3: Cell transmission channels RACH (Random Access Channel, Random Access Channel) and FACH (Forward Access Channel, Forward Access Channel) are all established successfully; [0006] Condition 1 is artificially causing the cell to be unavailable, which is not within the scope of the present invention. ...
