Abstract
The present invention discloses a method for transferring a context and a mobility management entity. When S1 handover occurs on an RN, the method includes: acquiring, by a source MME to which a UE is attached, an indicator for transferring a context of the UE, where the UE is a UE served by the RN when the S1 handover occurs; and transferring, by the source MME to which the UE is attached, the context of the UE to a target MME according to the indicator for transferring the context of the UE, so that the target MME acquires security information of the UE according to the context of the UE, where the target MME is an MME to which the UE needs to be attached in the handover process.
