Function Documentation

unsigned int gsm0502_calc_paging_group ( struct gsm48_control_channel_descr chan_desc,
uint64_t  imsi 
)
uint32_t gsm0502_fn_remap ( uint32_t  fn,
enum gsm0502_fn_remap_channel  channel 
)

Calculate the frame number of the beginning of a block.

Parameters
[in]fnframe number of the block ending.
[in]channelchannel type (see also enum fn_remap_channel).
Returns
frame number of the beginning of the block or input frame number if remapping was not possible.
