This invention addresses the problem of latency of response regarding
information relying on an IMEISV from a CN. This is possible by defining
the early RRC connection bits' indication to determine the supported
signalling schemes and providing the IMEISV information from the terminal
to the network. After this point the CN is able providing this mapping
information to the radio access network before actual radio links are
utilized. The idea here is for early RRC message information to be used
for indicating what version of bitmap correction terminal capabilities
refers to and what procedures can be utilized while waiting for this bit
map information from the CN. Using this approach the length of the early
RRC message can be kept short, the content of corrections can be well
defined saving signalling bits, and the concern of a fast available
indication on the connection set-up phase can still be addressed.
