GSM Frequency Analysis Application

Scenarios

Scenarios of GSM frequency analysis are as follows:

Perform frequency optimization for some key cells after frequency planning on

the entire network.

Perform frequency optimization for cells with poor network quality or VIP cells.

Select frequencies for capacity expansion of cells.

Output the interference matrix to be used by other tools for frequency analysis.

Query (Frequency Optimization)

Meanings of values in the frequency

separation rule table are as follows:

Difference values of absolute frequencynumbers of two frequencies must be

greater than the set value:

0: Difference value of absolute frequencynumbers must be greater than or equal to

0 (that is, there is no restriction).

1: Difference value of absolute frequency

numbers must be greater than or equal to

1 (that is, the cells must not be configured

as intra-frequency cells).

2: Difference value of absolute frequency

numbers must be greater than or equal to

subscriber who has complaints in the wireless network.

The Nastar provides the complaint analysis support of a maximum of 2000 subscribers.

Supported analysis time range: The Nastar supports the analysis of subscriber complaints generated in the past seven days.

Query (2)Signaling procedure before call release:

1.For complaints of common subscribers, the Nastar provides the function of analyzing key signaling before call release.

For complaints of VIP subscribers, the Nastar provides the full signaling analysis of calls.2. The signaling analysis provides two analysis methods, namely, signaling flow table and signaling flow chart.

Tip: Double-click a signaling record. The dialog box for

viewing detailed signaling information is displayed.

Tip: Click a signaling record. The signaling flow

figure is interacted with data in the signaling flow

Tip: The function is used together with the neighboring cell, MR,

frequency, and uplink interference analysis functions to improve

the efficiency of solving subscribers' complaints.

Measurement information before call release:

1. For complaints of common subscribers, the Nastar provides the function of analyzing a few measurement reports before call release.For complaints of VIP subscribers, the Nastar provides the measurement analysis of the entire call process.

2. The measurement information analysis function provides two analysis methods, namely, measurement information table and measurement
