Abstract: This application provides a communication method and a communication system. A central unit (CU) obtains a quality of service (QoS) parameter of a QoS data flow and performs mapping the QoS data flow to a bearer based on the QoS parameter of the QoS data flow. The CU determines a QoS parameter of the bearer based on the QoS parameter of the QoS data flow and sends a context setup request message to a distributed unit (DU), wherein the context setup request message comprises the QoS parameter of the bearer, the QoS parameter of the QoS data flow and the mapping relationship between the QoS data flow and the bearer.

Abstract: The present disclosure relates to terminal devices, access network devices, air interface configuration methods, and wireless communications systems. In one example method, a second access network device in a radio access network determines air interface configuration information of an air interface between a terminal device and the radio access network, and sends a first air interface configuration message comprising the air interface configuration information to a first access network device in the radio access network. The first access network device and the second access network device use different wireless communications standards.

Abstract: Embodiments of the present disclosure provide a multi-connectivity communication method and a device. An access network device of an LTE network sets up a second connection for UE and splits data of the UE through the second connection. The second connection is a connection set up between the UE and the access network device of the LTE network through an access network device of a next generation network. Therefore, dual connectivity between the UE and the LTE network and the next generation network is implemented, a data transmission rate of the UE is increased, and a throughput of the entire network can be increased.

Abstract: A multi-connectivity communication method includes: a secondary base station receives a first RRC message generated by an RRC entity of an anchor base station and a second RRC message generated by an RRC entity of the secondary base station. The secondary base station sends the first RRC message and the second RRC message to the terminal via an air interface between the secondary base station and the terminal, where a PDCP header, an RLC header, or a newly added adaptation layer carries indication information, the indication information is used to indicate a target RRC entity that generates an RRC message, the target RRC entity is the RRC entity of the anchor base station or the RRC entity of the secondary base station, and the anchor base station and the secondary base station use different radio access technologies.

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.

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.
