Patent ID: 8855643

Claim:
A method for improving a handover success rate of a group of mobile terminals, comprising: obtaining, by a mobile proxy, a maximum congestion adjustment time value according to obtained access parameters, wherein the maximum congestion adjustment time value is a maximum delay time value for adjusting an arrival rate of location update request messages; obtaining, by the mobile proxy, a minimum backoff time value according to the obtained access parameters, wherein the minimum backoff time value is less than the maximum congestion adjustment time value; receiving, by the mobile proxy, a message from a mobile terminal after entering a new cell; if the message is a handover request message, sending, by the mobile proxy, the message to a base station without waiting for expiry of a predetermined time after the message is received; if the message is not the handover request message, sending, by the mobile proxy, the received message to the base station upon the expiry of the predetermined time after the message is received, wherein the predetermined time is greater than or equal to the minimum backoff time value, and the minimum backoff time value is a minimum time value of the predetermined time when the message received from the mobile terminal is not the handover request message, and the predetermined time is less than or equal to the maximum congestion adjustment time value.
