System and method for a previously activated mobile station to challenge network mobile station knowledge during over the air activation

摘要

A system and Method are presented for Activation by Air (OTA) of a Mobile Station previously activated in a Telecommunications Network.During the new activation, a Processor of the cativacion Go requested by the configuration data of the mobile station.The mobile station can broadcast the first test the Processor Activation by air and it sends a test message to include certain parameters of the mobile station to eL Processor Activation by air.Then, the Processor communicates its Activation by Air Reconnaissance Center of Information NetworkReturn a message that originates from certain parameters of the test of the Mobile Station sends the message and return the test to the mobile station.The Mobile Station Validates the message return Test and if the validation is successful,The Mobile Station over the transfer of the configuration data of the mobile station to the Processor Activation by air.The Centre of recognition uses one of the Safety Locking Test Data (SSD shared secret Data (c) allowance and shared Secrets (ssd0 _ s hard not to broadcast over the air)Nte the generation of feedback message of the test.For this purpose,The Reconnaissance Center Stores the SSD _ D and selector of Shared Data (SSD _ Select) sent by the mobile station as one of the parameters passed to the applicationTest. Then, the Processor sends the Activation by Air New operating parameters and requests the......
