 The  BTS  provides  two-way  radio communication  between  the  PSTN  and Mobile  Station  (Mobile  Set)  located  in  a single  GSM  cell.  It  also  provides  a  similar link  between  the  mobile  station  and  the rest  of  the  networks.  The  BTS  provides  on interface  for  the  digital  baseband  signals used  by  the  land  based  networks  and  the GSM radio signals used by mobile station.

For  system  incorporating  GPRS  some additional components are required as shown  the  below  figure.  An  MFS  is placed in the system between the BSC and SGSN. The MFS contains a number of PCUs, one of which controls all  the GPRS activity for the one cell.

A serving GPRS support node (SGSN)  is responsible for the  delivery  of  data  packets  from  and  to  the  mobile stations  within  its  geographical  service  area.  Its  tasks include  packet  routing  and  transfer,  mobility management  (attach/detach  and  location management),  logical  link  management,  and authentication  and  charging  functions.  The  location register  of  the  SGSN  stores  location  information  (e.g., current  cell,  current VLR)  and user  profiles  (e.g.,  IMSI, address(es)  used  in  the  packet  data  network)  of  all GPRS users registered with this SGSN.

Functional Architecture of BTS

Page 8: Al-Catel BTS Presentation Complete

Channel OrganizationRF  signals  over  the  Air  interface  carry  traffic  and signaling/Control  channels  which  are  organized according  to  GSM  recommendations.  The  allocation and control of these channels are managed by the BTS functions.Radio  Resource  Management  function  controls  and organize  radio  resources  to  meet  current  operational needs of both the networks and individual.

Functional Architecture of BTS

Page 9: Al-Catel BTS Presentation Complete

As  the  principal  interface  between  the  PSTN  and  Mobile Stations, the BTS performs four primary functions. Transmission function, which manage the transfer of traffic and control data between the BTS and BSC.Telecommunication  functions,  which  manage  the  transfer  of traffic and control data between the BTS and Mobile Station.O&M function, which supervise the operation of the BTS.Support  function,  which  provides  a  logical  and  physical environment in which the BTS functions can be realized.

BTS Functions

               Communication between  the  transmission,  telecommunication, and O&M  functions  is managed according  to  the OSI model.  The BTS functions are concerned with  layer 1 (Physical), Layer 2 (Data Link), and Layer 3 (Network) of this

        model.

Page 10: Al-Catel BTS Presentation Complete

To minimize operating costs, all data passed between the BTS and BSC in Time division multiplexed onto a single physical interface. This is the Abis Interface, which carries all the data sent between the BSC and BTS. Logical links between the BSC and BTS handles the following information:

Transmission Functions

Signaling data used for control purposes

O&M data for the BTS transmission module

O&M data for the BTS entities

User data in the form of speech and data traffic.

User data in the form of speech and data traffic.

Page 12: Al-Catel BTS Presentation Complete

For BTS and BSC multiplexing equipment is normally connected using dedicated cabling. Other method of Abis Interface connection can be used for BTS, where the installation of the dedicated cabling in not possible. In this case, control of the transmission medium is in the hands of third party.

Abis Interface:

Microwave Link (used where line of sight radio path is available.

Leased  Line  (Copper  Cable  or  Fiber  Optic  used  where  the 

distance between the BSC and BTS is too great for microwave).

Satellite  Link  (Used  where  Previous  two  methods  are  not 

possible) 

Page 13: Al-Catel BTS Presentation Complete

There are two primary telecommunication functions:

Telecommunication Function

Based band funcations modulate and encode traffic and signaling data from the BSC according to GSM recomendaitos. This data  is then sent to the Mobile Stations using the RF function. Traffic and signaling  received  from  the Mobile  Stations  is  demodulated  and decoded to recover the baseband data. 

Baseband Functions:

Page 14: Al-Catel BTS Presentation Complete

Telecommunication Function

RF  functions  enable  traffic  and  signaling  to  be  sent  and  received over the Air Interface as a radio signal. A special link layer protocol ensures  the  reliable  transfer  of  signaling  data  over  the  Air Interface.For antenna Diversity, the telecommunication function uplink path is duplicated. The duplicated functions  intend from the antennas, through the RF functions.

RF Function:

Page 15: Al-Catel BTS Presentation Complete

O&M Functions

O&M  functions monitor  and  control  the  correct operation of  the BTS and its external interfaces. These function are shared between the BTS and BSC. The BSC provides overall control.The  O&M  function  use  Layer  2  links  for  BTS  internal communications.  A  terminal  connected  via  an  MMI  is  used  for local operator control of the BTS.

There are four categorized of O&M function:Configuration ManagementFault ManagementDedicated Alarm and Control HandlingExternal Alarm Handling.The O&M function also control the operation of the RF self-tests and manage the actions required by the BTS recovery Strategy.

Page 16: Al-Catel BTS Presentation Complete

Support Function

The support function provides a number of services relevant to the internal working of the BTS are:

Clock generation and distribution.

External alarm collection.

Internal self tests.
