 Guidelines  for  Cellular  SID  Administrators 


 1.0  PURPOSE  AND  SCOPE 
 This  document  contains  guidelines  for  the  FCC-  recognized  Administrators  for  Cellular  System  Identifier  Numbers  (SIDs)  within  the  United  States. 


 1.1  Since  the  early  1980’s,  Cellular  SIDs  have  been  assigned  by  the  FCC  and  have  been  a  required  element  of  the  FCC  authorization. 
 1.2  In  August  2002,  the  Commission  adopted  an  Order  to  eliminate  SIDs  from  being  a  required  element  of  the  license  and  to  transition  the  administration  of  SIDs  to  the  private 
 sector. 


 2.0  CELLULAR  SID  FUNCTION 
 2.1  System  Identification  Numbers,  or  SIDs,  are  numeric  identifiers  assigned  to  cellular  systems.  SIDs  are  transmitted  by  the  cellular  system  so  that  the  cellular  mobile  stations 
 can  determine  whether  the  system  through  which  they  are  communicating  is  a  system  to  which  they  subscribe,  or  whether  they  are  considered  by  the  system  to  be  roamers. 


 3.0  ASSUMPTIONS  AND  CONSTRAINTS 
 These  guidelines  are  based  on  the  following  assumptions  and  constraints: 
 3.1  These  guidelines  should  provide  the  greatest  latitude  to  those  providing  cellular  services  while  permitting  the  effective  and  efficient  management  of  a  finite  resource. 


 3.2  The  Cellular  SID  Administrators  initially  recognized  by  the  FCC  are  responsible  for  developing  an  efficient  process  for  administering  Cellular  SIDs  in  a  multiple 
 Administrator  environment.  The  process  will  be  reviewed  by  the  FCC  and  then  incorporated  in  these  Guidelines  under  Section  7.0. 


 3.3  A  Cellular  Carrier  can  request  a  SID  from  any  one  of  the  FCC-  recognized  Cellular  SID  Administrators. 
 3.4  New  Cellular  SID  Administrators  can  be  recognized  by  the  FCC  by  filing  a  letter  of  intent  and  certifying  they  will  comply  with  the  guidelines  and  then  signing  a 
 Memorandum  of  Understanding  with  the  Wireless  Telecommunications  Bureau.

 4.0  ASSIGNMENT  PRINCIPLES 
 The  assignment  principles  defined  below  allow  cellular  systems  the  greatest  possible  latitude  in  providing  seamless  roaming  capabilities. 


 4.1  Information  requested  from  applicants  for  Cellular  SID  numbers  will  be  kept  uniform  and  kept  to  a  minimum. 
 4.2  Maintain  the  current  practice  of  assigning  odd  number  SIDs  to  Channel  Block  “A”  licensees  and  even  number  SIDs  to  Channel  Block  “B”  licensees. 
 4.3  The  assignment  of  a  Cellular  SID  number  does  not  imply  ownership  of  the  Cellular  SID  number. 
 4.4  If  a  license  experiences  a  transfer  of  control  or  assignment  of  authorization,  the  authorized  use  of  the  Cellular  SID  remains  with  the  license. 
 4.5  A  request  to  use  a  SID  assigned  to  another  carrier  must  be  accompanied  by  a  notice  stating  that  the  authorized  SID  user  concurs  with  the  request 


 5.0  RESPONSIBILITIES  OF  CELLULAR  SID  ADMINISTRATORS 
 These  general  guidelines  will  be  used  by  the  Cellular  SID  Administrators  in  reviewing  and  processing  requests  for  a  SID.  A  Cellular  SID  Administrator  will: 


 5.1  Assign  a  Cellular  SID  number  to  any  FCC  licensed  cellular  carrier  who  submits  the  appropriate  request  for  a  SID  assignment. 
 5.2  Assign  SID  numbers  in  a  fair,  timely  and  impartial  manner  to  any  applicant  that  meets  the  criteria  for  assignment  (see  5.1). 
 5.3  Assign  SID  numbers  on  a  first  come,  first  served  basis  from  the  available  pool. 
 5.4  Request  the  minimum  information  necessary  to  make  a  SID  assignment. 
 5.5  Assign  the  number  of  SIDs  requested  based  on  industry  practices. 
 5.6  Treat  sensitive  information  received  from  applicants  as  proprietary  and  confidential,  and  not  to  be  shared  with  non-  administrator  personnel. 


 5.7  Charge  a  reasonable  fee,  based  on  current  practice,  for  the  service  rendered.  It  is  noted  that  the  Commission  charges  a  fee  of  $85  (February  2003). 
 5.8  Provide  the  Public  with  access  to  a  complete  listing  of  assigned  SIDs  updated  annually. 


 6.0  RIGHTS  AND  RESPONSIBILITIES  OF  CELLULAR  SID  APPLICANTS  AND  ASSIGNEES 


 Entities  requesting  a  Cellular  SID  assignment  shall: 
 6.1  Keep  administrative  information  current  with  an  Administrator. 
4
 6.2  Have  the  right  to  request  a  SID  from  any  one  of  the  recognized  Cellular  SID  Administrators 
 6.3  Comply  with  all  applicable  regulations. 


 7.0  CELLULAR  SID  ASSIGNMENT  PROCEDURES 
 7.1  [Reserved  for  the  SID  assignment  procedures,  including  the  coordination  of  SID  assignments  in  a  multi-  administrator  environment.  Procedures  will  be  developed  by  the 


 initial  FCC-  recognized  SID  Administrators.] 


 8.0  MAINTENANCE  OF  GUIDELINES 
 8.1  The  Cellular  SID  Administrator  Guidelines  can  be  changed  upon  agreement  between  the  FCC  and  the  recognized  Cellular  SID  Administrators.
