BSS C O NFI GUR ATI ON AND U SER G UIDE 2. BSS Overview The base station subsystem (BSS) is responsible for setting up, maintaining, and terminating the radio connections towards the mobile station (MS). BSS is a common resource where the same equipment and frequencies are used for both packet-switched and circuit-switched traffic. It can handle GSM 850, 900, 1800, and 1900 bands. The WorldGSM™ BSS supports both transmission distribution mode (TDM) and internet protocol (IP) interfaces.
PAGE 16
BSS C O NFI GUR ATI ON AND U SER G UIDE • Base station controller (BSC) • Base transceiver station (BTS) BSC The BSC provides all the control functions and physical links between the mobile switching center (MSC) and BTS. BSC is a high-capacity switch that provides capabilities such as handover, cell configuration data, and control of radio frequency (RF) power levels in BTSs. In an area, the BTS connects to the BSC through the Abis interface. The BSC 500i is a table-top equipment.
PAGE 17
BSS C O NFI GUR ATI ON AND U SER G UIDE The network management supports the configuration, supervision, and the maintenance of the network resources and services. VNL® network management provides the necessary input to higher service-level management, business support systems, and other administrative systems.

BSS C O NFI GUR ATI ON AND U SER G UIDE ME after performing the action. This changes the operational state of the ME to enable. • Unlock: In this state, you cannot perform any action on the ME. However, there is an exception with the cell table. You can modify the handover and power control parameters in unlocked state. 2.2.2 Operational States Operational state of a ME tells you the functional state of that ME. The change in the operational state of a ME depends on the internal working of BSC.

BSS C O NFI GUR ATI ON AND U SER G UIDE • Disconnect: Used to disconnect a ME from a network. • Shut Down Active: Used to shutdown a ME, which is in active state. The standby card becomes active. This puts the card in hot swap state (meant for maintenance purpose) and you can jack-out the card. This is also called as graceful shutdown of the processes. • Shut Down Standby: Used to shutdown a ME, which is in standby mode.

BSS C O NFI GUR ATI ON AND U SER G UIDE 3. Managing the BSS Node This section describes the procedure to add the BSS node in OMC. In addition, this section describes the different modes for viewing the BSS node and configuration of trunkport. 3.1 Adding a BSS Node The addition of BSS node in OMC is a two-step process: 1. The registration of BSS node with the OMC server. 2. Assigning the BSS node to hierarchy. Registration is an automatic process that BSS node initiates.
PAGE 23
BSS C O NFI GUR ATI ON AND U SER G UIDE 3.1.1 Registering the BSS Node When you start (power-up) the BSS node, it initiates the registration process and sends its information to the OMC server. The IP address of the communicating OMC server is in the default factory settings of the BSS node. The following steps take place during the registration of the BSS node: 1. When BSS node is powered-up, it tries to connect to the designated OMC over transmission control protocol (TCP) interface. 2.
PAGE 24
BSS C O NFI GUR ATI ON AND U SER G UIDE 3.1.2 Assigning the BSS Node to Hierarchy You can view the settings and configure the BSS node after moving the BSS node from unAssigned hierarchy to another hierarchy. The following are the steps to assign the BSS node to the default hierarchy: 1. Open the Network Explorer window and double-click unAssigned hierarchy. All the existing unAssigned nodes appear in right-pane. 2.
PAGE 25
BSS C O NFI GUR ATI ON AND U SER G UIDE 3.2.1 Viewing Mode In this mode, you can only view the configuration details of a BSS node. You cannot edit any ME or fields of a ME.

BSS C O NFI GUR ATI ON AND U SER G UIDE Appendix.A Approaches for Adding BSS Node At OMC, you can add BSS node in the following two ways: • Bottom-up approach • Top-down approach VNL® recommends that you add a new BSS node by using the bottom-up approach because in this approach the node registers automatically with the OMC. However, while adding a BSS node by using bottom-up or top-down approach the node should have a reachable IP. Otherwise, the OMC is not able to register the new node.
