Embodiments of this application provide security protection methods and apparatuses. One method includes: obtaining, by a master station, a user plane security policy, wherein the user plane security policy indicates whether to activate a user plane security protection, the master station communicates with a secondary station under a dual connectivity scenario; sending, by the master station, a message comprising the user plane security policy to the secondary station; receiving, by the secondary station, the message from the master station; and determining, by the secondary station, a user plane security algorithm based on the user plane security policy.

This application provides a data delivery status indicating method and an apparatus, to effectively indicate a data delivery status, facilitate more accurate flow control, and save transmission resources. A communication method is provided. The method includes a first network node sends data to a terminal device. The first network node sends first indication information and second indication information to a second network node. The first indication information indicated information about a highest sequence number (SN) successfully delivered in sequence in the data. The second indication information indicates information about an SN that is delivered after the highest SN.

Data delivery status indicating method and apparatus

A core network delivers two sets of quality of service (QoS) parameters to an access network device. The access network device selects one of the two sets of QoS parameters, and indicates the selected set of QoS parameters to the core network. An air interface rate required by the set of QoS parameters can be supported by a radio access network (RAN). In this way, a QoS parameter applied to a related user equipment (UE), a related bearer, a related packet data unit (PDU) session, or a related QoS flow can be effectively determined, and a hardware capability of an LTE base station does not need to be upgraded. In addition, the core network may set, based on a QoS parameter selected by a RAN side, a corresponding QoS management policy such as a rate adjustment policy, to facilitate data transmission between UE and the core network.

Signal transmission method, network device, and system

Embodiments of this application provide a data sending method, apparatus, and system, and relate to the communications field, so that an SN change in dual connectivity does not affect performance of a network in which an MN is located. The data sending method specifically includes: determining, by a source node device, whether direct data forwarding is supported between the source node device and a destination node device; and sending, by the source node device, a first message including a first indication to a first node device, where the first indication is used to indicate whether the direct data forwarding is supported between the source node device and the destination node device. This application is used for data sending.

Data sending method, apparatus, and system

This patent application provides a multi-connectivity data reporting method, including: obtaining, by a first network device, a first data volume report, where the first data volume report is used to indicate a volume of data that are of a terminal device and that pass through a second network device; and sending, by the first network device, the first data volume report to a third network device. The first data volume report includes one or more of QoS flow identifiers (QFIs) of one or more quality of service QoS flows, identifiers of one or more protocol data unit (PDU) sessions to which the one or more QoS flows belong, or data volumes of the one or more QoS flows.

Multi-connectivity data volume reporting method

Example communication methods and apparatus are described. One example method includes that a first communications apparatus sends quality of service (QoS) flow information to a second communications apparatus, where a QoS flow indicated by the QoS flow information corresponds to at least one bearer type. The first communications apparatus receives a QoS flow list sent by the second communications apparatus based on the QoS flow information, where each QoS flow list is mapped to a radio bearer. The first communications apparatus sends a radio bearer identifier of the QoS flow list to the second communications apparatus. In the embodiments of this application, a base station itself determines a radio bearer or a DRB used to transmit the QoS flow.

Resource push method and apparatus

According to a synchronization method and apparatus provided in this application, a source station sends location information of the source station; and after obtaining a signal propagation delay that is calculated according to the location information of the source station and location information of a to-be-synchronized station, the to-be-synchronized station performs synchronization with the source station according to a synchronization reference time obtained by subtracting the propagation delay from a receiving time of a first network reference signal received from the source station. It can be learned that, in a process in which the to-be-synchronized station performs synchronization with the source station, the signal propagation delay between the to-be-synchronized station and the source station is used to compensate for the receiving time of the first network reference signal. Therefore, the consumed propagation delay can be subtracted from the synchronization reference time, so that synchronization accuracy is improved.
