Adding a Common BTS

This describes how to add a common BTS in IP transmission mode for the BSC, and how to configure the site device attributes, cell basic attributes, and TRX attributes.

Scenario	BSC initial configuration and BSC capacity expansion
Mandatory/Optional	Mandatory

NOTE:

The BTS in IP transmission mode does not support the Ring Mode , Config AbisByPass or Backup OML function, and does not support cascading configuration.

Only the BTS3012, BTS3012AE, and BTS3012 II support the IP transmission mode.

The BTS in IP transmission mode cannot extract clock from the BSC directly. Its clock is provided by the IP clock server.

The BTS in IP transmission mode supports the device IP address and the port IP address. Select a specific transmission mode by setting BTS Communication Type. On the LMT, the port IP address of the BTS is used for transmission by default. When the device IP address is used in communication, the BTS routes must be configured; when the port IP address is used in communication, you do not need to configure the BTS routes.

Prerequisites

Preparation

NOTE:

The following procedure takes how to add a BTS on the GFGUB in the GEPS as an example.

Procedure

1. On the BSC6000 Local Maintenance Terminal, right-click the GFGUB in the GEPS.
2. Choose Add Site. A dialog box is displayed, as shown in Figure 1.
   Figure 1 Add Site dialog box (1)
   
   

3. Click Add Site. A dialog box is displayed, as shown in Figure 2.
   Figure 2 Add New Site dialog box
   
   

4. Set the parameters by referring to Table 1.
   NOTE:

   The Support Separate option is available only for the BTS3012, BTS3012 II, and BTS3012AE. If Support Separate is selected, the BTS3012, BTS3012 II, and BTS3012AE can be configured with the DTRU/QTRU.

5. Click OK. A dialog box is displayed, as shown in Figure 3.
   Figure 3 Add Site dialog box (2)
   
   

6. Click Next. A dialog box is displayed, as shown in Figure 4.
   Figure 4 Add Site dialog box (3)
   
   

7. Select a BTS, and then click Add Cell. A dialog box is displayed, as shown in Figure 5.

8. Set the parameters by referring to Table 1.
   NOTE:

   To add multiple cells at a time, set Number of Cells. The added cells are named in the form of current Cell Name + sequence number.

9. Click OK. A dialog box is displayed, as shown in Figure 6.
   Figure 6 Add Site dialog box (4)
   
   

10. Click Next. A dialog box is displayed, as shown in Figure 7.
    Figure 7 Add Site dialog box (5)
    
    

11. Click Site Attributes. A dialog box is displayed, as shown in Figure 8.
    Figure 8 Site Device Attributes dialog box
    
    

12. Double-click DDPU. A dialog box is displayed, as shown in Figure 9.
    Figure 9 Set Antenna Feeder Property dialog box
    
    
    NOTE:

    • This takes the configuration of one antenna feeder port on the DDPU as an example. If the antenna feeder port is not required, you can delete the DDPU.
    • You have to specify at least one TRX for the downlink tributary of the DDPU. For other tributaries, use the default settings.
    • The DDPU has two paths: A and B. The two paths are independent of each other. The data configurations of the DDPU must be consistent with the physical connections, and the frequency band of the TRX must be the same as the frequency band of the DDPU.

13. Set the parameters by referring to Table 1, as shown in Figure 10.
    Figure 10 Setting antenna feeder attributes
    
    

14. In the dialog box shown in Figure 8, right-click an empty slot in the DTRU and choose Add Board > TRU from the shortcut menu. A TRU is added.
15. Right-click the added TRU and choose Binding logical TRX from the shortcut menu. A dialog box is displayed, as shown in Figure 11.

    BTS3012, BTS3012AE, BTS3012_II, DBS3900, BTS3900, BTS3900A, BTS3900B, and BTS3900E do not support that Muplex Mode is set to HALF.

    The parameter Peer Port IP address index specifies the index of the valid IP address for a BSC port. The BSC supports the setting of multiple IP address under one Port No.. The Peer Port IP address index maps the valid IP address of the BSC port. After the value of Peer Port IP address index is specified, the BSC IP Address in the IP Interface Board Parameter of BTS tab page is generated automatically and the BSC IP Address cannot be changed.

22. Click the PTU parameter of BTS tab to display the tab page, as shown in Figure 14.

    NOTE:

    • For two cells, the values of at least one of the following parameters should be different: MCC, MNC, LAC, and CI.
    • If you select GPRS Support, the BSC must be configured with the built-in PCU. If the BTS does not support the GPRS function or the GPRS services are unavailable in the cell, do not select GPRS Support.
