Many thanks!

大神們 請(qǐng)教下

1. TMSI在哪里中情況下會(huì)失效，這個(gè)失效是手機(jī)和網(wǎng)絡(luò)都認(rèn)定的嗎？

   A.關(guān)機(jī)，detach？

   B.detach一段時(shí)間？長(zhǎng)時(shí)間不做TAU導(dǎo)致impicity detach？

   C.UE進(jìn)到無(wú)服務(wù)區(qū)域一段時(shí)間？我想知道進(jìn)入一段時(shí)間之后，如果再回到之前有服務(wù)的那個(gè)小區(qū)時(shí)候TMSI還有效，是不是跟這個(gè)時(shí)間有關(guān)？

   請(qǐng)問(wèn)還有其他的嗎？

2.在Attach，LU/RAU/TAU，service request 和RRC連接請(qǐng)求里 都用TMSI嗎？那些情境不是用TMSI的？

    A.第一次插卡開(kāi)機(jī)

    B.TMSI在網(wǎng)絡(luò)端失效（第一問(wèn)中的）

    C.換了新的LAI時(shí)候的LU

請(qǐng)問(wèn)還有其他的嗎？
