Full Description

The present document specifies the layer 3 procedures used on the Base Station System (BSS) to Mobile-servicesSwitching Centre (MSC) interface for control of GSM services.

For the purposes of call control and mobility management, messages are not interpreted at the Base Station System(BSS) which acts as a relay function. These messages and procedures are documented in 3GPP TS 04.08, the onlyrelevant issues covering these messages in the present document are those concerned with error conditions at theinterface, and the headers that are required for the correct addressing of the messages. This is specified in more detail in3GPP TS 08.06.

The functional split between MSC and BSS is defined in 3GPP TS 08.02 and states that the BSS is responsible for localradio resource allocation and in order to support this the required procedures between BSS and MSC are defined indetail in the present document.

3GPP TS 08.02 also states that the BSS is responsible for the scheduling of all CCCH/BCCH messages and thereforesome procedures for providing the BSS with the necessary information to be passed on these channels for individualcalls (i.e. paging) are defined in the present document, but the scheduling is not discussed.

This interface and consequently these layer 3 procedures are designed to support BSSs providing one or more cells.
