发明名称 Method for synchronizing a security start value in a wireless communications network
摘要 In a 3GPP system, a UE can process two RRC messages independently of each other, each of which may contain a START value for the same domain. To avoid loss of synchronization between the UE and the UTRAN with respect to these START values, in a first embodiment a UE ensures that the START values in the two messages are identical if the first message has not been fully acknowledged before the transmitting of the second message. In a second embodiment, the UTRAN only updates its "most recently received" START value if the message from the UE contains a greater-valued START value. In a third embodiment, only START values as embedded within a INITIAL DIRECT TRANSFER message are utilized by both the UE and the UTRAN in a Security Mode procedure.
