  • Patent number: 10779195
    Abstract: This application discloses an information transmission method in a communication system. According to the method, a master base station sends a request message to a secondary base station for requesting to transfer one or more flows from the master base station to the secondary base station for transmission to a terminal device. The request message carries one or both of identification information of each flow, and information of a data radio bearer (DRB) associated with each flow. The master base station receives a response message from the secondary base station, indicating whether each of the one or more flows is admitted or rejected by the secondary base station. Based on the identification information of the flows, DRBs are mapped to the flows. QoS management of information transmission is more refined, and requirements of 5G communication systems for QoS management of information transmission in a dual connectivity scenario can be met.

  • Patent number: 10750422
    Abstract: The present application discloses a method and an apparatus. In the present application, a radio access network RAN server receives a measurement report from a terminal, determines a target inter-RAT cell of the terminal based on the measurement report, and configures a resource for the terminal in the target inter-RAT cell. The configured resource is a resource to be used by the terminal to access the target inter-RAT cell. The RAN server sends a handover command to the terminal. The handover command is used to instruct the terminal to hand over to the target inter-RAT cell, and the handover command carries an identifier of the target inter-RAT cell and information about the configured resource. In this way, when handover is performed between inter-RAT cells, handover can be implemented without across core networks, thereby reducing signaling exchange between a source core network and a target core network.

  • Patent number: 10750409
    Abstract: A method and an apparatus for non-access stratum (NAS) message processing during handover in an evolved network are provided. The method includes the following steps. An evolved packet core (EPC) receives a message which indicates that a UE is being handed over sent by a source evolved NodeB (S-eNB), and stops sending an NAS message to the UE temporarily. The EPC receives a message which indicates that the UE returns to an S-eNB service area sent by the S-eNB. The EPC sends the NAS message to the UE through the S-eNB, if needed. With the method and the apparatus, the EPC can acquire a location of the UE in time in the case of a handover failure of the UE, a time limit of a retransmission timer is set precisely, and a specific implementation for forwarding an NAS message through an X2 interface is provided.
