Semantics description<br />

The TMSI/ PTMSI consis<strong>ts</strong> of<br />

4 octe<strong>ts</strong> (32bi<strong>ts</strong>). This can be<br />

represented by a string of bi<strong>ts</strong><br />

numbered from b0 to b31, with<br />

bit b0 being the least<br />

significant<br />

The "Routing parameter" bit<br />

string consis<strong>ts</strong> of bi<strong>ts</strong> b14<br />

through b23 of the TMSI/<br />

PTMSI. The first/leftmost/most<br />

significant bit of the bit string<br />

contains bit b23 of the TMSI/<br />

PTMSI.<br />

another PLMN; or, PTMSI<br />
