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.
Abstract:
The present invention provides a method for processing an enhanced physical downlink control channel (EPDCCH), a network-side device, and a user equipment. The method includes: notifying a user equipment (UE) of M physical resource block (PRB) sets used for EPDCCH transmission and N reference signal (RS) configurations used for EPDCCH downlink control information (DCI) rate matching and/or EPDCCH resource mapping, and notifying the UE of correspondence between the M PRB sets and the N RS configurations, where N is a positive integer greater than 1, and M is a positive integer; and performing the EPDCCH DCI rate matching and/or the EPDCCH resource mapping according to the correspondence between the M PRB sets and the N RS configurations.
Abstract:
The present invention relates to the field of communications technologies and provides a relay node handover method. The method includes: receiving, by a target base station, a handover request sent by a source base station serving a relay node; acquiring, by the target base station, first transport network layer TNL information from the source base station; and establishing, by the target base station, a connection with the relay node according to the first TNL information. The present invention further provides a base station and a communication system. The present invention may implement the handover of a relay node from a source base station to a target base station, thereby ensuring the establishment of a connection between the relay node and the target base station.
Abstract:
The present disclosure relates to the field of communications technologies and discloses a method, a device, and a communication system for establishing a connection with a network management system. The method includes: obtaining, by a relay node, a first IP address of the relay node; obtaining, by the relay node, an IP address of a security gateway by using the first IP address of the relay node; establishing, by the relay node, an IP security tunnel with the security gateway according to the IP address of the security gateway; obtaining, by the relay node, a second IP address of the relay node and an IP address of the network management system through the IP security tunnel; and establishing, by the relay node, a connection with the network management system by using the second IP address of the relay node and the IP address of the network management system.
