Patent ID: 8688123

Claim:
A method for transmitting a mobility state, comprising: when performing a handover of a user equipment (UE) in connectivity state from a source evolved NodeB (eNB) to a target eNB, the source eNB or the target eNB deciding the mobility state of the UE which indicates a speed level of the UE according to UE historical information in a service keeping period; wherein when the handover is an S1 handover, S1 being a logical interface between an Evolved Packet Core (EPC) and an eNB: the source eNB sends a handover request message carrying the UE historical information to the target eNB via a mobility management entity (MME), and the target eNB extracts the UE historical information from the handover request message, and decides the mobility state of the UE according to the UE historical information; or the source eNB decides the mobility state of the UE according to the UE historical information, and carries corresponding mobility state instruction information in the handover request message to send to the MME, the MME forwards the handover request message to the target eNB, and the target eNB acquires the mobility state corresponding to the UE according to the mobility state instruction information in the handover request message; when the handover is an X2 handover, X2 being a logical interface between eNBs: the source eNB sends the handover request message carrying the UE historical information to the target eNB, and the target eNB extracts the UE historical information from the handover request message, and decides the mobility state of the UE according to the UE historical information; or the source eNB decides the mobility state of the UE according to the UE historical information, and carries the corresponding mobility state instruction information in the handover request message to send to the target eNB, and the target eNB acquires the mobility state corresponding to the UE according to the mobility state instruction information in the handover request message.
