  1. What to do When TAC Run out John Talbot BABT Paul Gosden, GSMA

  2. TAC Allocated Since 2004

  3. Old IMEI Format

  4. Current IMEI Format Note: For NN = 35, initially YY was fixed at 00 and is subsequently incremented when XXXX reaches 9999

  5. Calculations to determine the lifetime of the remaining TAC numbers beginning 35 • For each TAC extension ( From 00 to 99) there are 8500 TAC numbers available since the first 1500 are reserved. • That gives a total of 850000 TAC numbers available. • There are approximately 31695 TAC numbers beginning 35 already allocated and currently in the system. • The number of TAC numbers allocated last year was approximately 8000 TAC numbers. • Based on these figures, the estimated lifetime of the pool of 35 TAC numbers has been calculated at differing % increases:

  6. Calculations to determine the lifetime of the remaining TAC numbers beginning 35 Since the 2008’s increase was approximately 30% up on the year previously and assuming that rate remains constant, that would give a lifetime of 13 years of 35 TAC

  7. Future requirements for TAC • The current demand for TAC in Mobile phones is increasing which is where we are seeing the current steady requirement from. • There is a added demand from Notebook vendors this will increase over the coming years but will never meet the current Mobile Phone requirements. • The huge demand will come from the requirements of the Machine to Machine market in modems. • Cars & Lorries • Vending Machines • Utility Meters

  8. Future requirements for TAC • If the predicted increase is 50% not 30% then the current 35 range of TAC will only last 9 Years • There are 75 reporting body numbers not started these would give a total of 75,800,000 TAC • At an annual increase of 50% the current TAC range would run out in approx 21 years. • We have a few TAC in reserve, these are Reporting Body numbers that were not fully used.

  9. So what do we need to do? • 21 Years is not long in the fast moving device manufacturing industry, and if the 50% increase is bigger, than we could only have 10 years before the TAC numbers are all gone? • If new hardware & software tools will be required we need to plan what is needed so that everyone concerned is given plenty of notice. • Should we allocate TAC in a different format of TAC for the M2M devices (e.g. 10 digit TAC numbers)? • So how can we increase the TAC range? • The old & the new TAC will need to be recognisable on the networks. • Who else do we need to engage in this discussion? • Is this nothing to do with DG and we should just send an LS to 3GPP?
