手機一陣子沒有連線上網，系統HLR清除掉SGSN位址紀錄，造成連線失敗，必需關機重開，當長時間沒有連線上網，有辦法讓HLR不會清除掉SGSN位址紀錄嗎？

HLR清除掉SGSN位址紀錄 won't cause PDP context failure.
As I know, this kind of scenario has been definded and prevented in 3GPP standard, and has already been tested and passed in operator's (FET, TCC, CHT) system acceptance test.
It's a highly possibility you have to check with your mobile.
