METHODS AND APPARATUS FOR EXPEDITIOUSLY RELEASING NETWORK RESOURCES FOR A MOBILE STATION BASED ON LOW BATTERY AND LOST SIGNAL CONDITIONS

摘要

Methods and apparatus for expeditiously releasing network resources for a mobile station based on low battery and lost signal conditions are disclosed. The wireless network ( 104 ) receives a power down warning message from the mobile station ( 102 ) indicative of a low battery condition. The wireless network ( 104 ) then identifies whether a lost signal condition exists with the mobile station ( 102 ). In response to receiving the power down warning message and subsequently identifying the lost signal condition, the wireless network ( 104 ) causes network resources for the mobile station to be released. The wireless network ( 104 ) infers that the mobile station ( 102 ) has powered down due to low battery without enough time to send a power down registration to the wireless network ( 104 ).
