sgsn: Make P-TMSI a local TLLI to avoid clash Some broken equipment does not convert the P-TMSI to a Local TLLI. This leads to the SGSN ignoring the GPRS Attach Complete message from the phone. Proprietary SGSNs and some documentation we found state that one should always set the two highest bits of a P-TMSI to one. This will help broken equipment and will avoid a potential P-TMSI/TLLI clash. The P-TMSI/Local TLLI mapping is now bijective.
