A communication method includes a first device that receives first indication information and a service flow identifier of a protocol data unit (PDU) session from a session management network element, where the first indication information indicates the first device to determine a transmission link for a service flow of the PDU session. The first device selects the transmission link for the service flow of the PDU session based on the service flow identifier and the first indication information.

Communication method and apparatus

The communication method according to the embodiments of this application is used to determine quality of service and/or charging control of a service flow of a terminal in a network that provides a service for a residential gateway, so as to ensure transmission quality of the service flow. A first control plane network element in a first network obtains a quality of service parameter and/or a charging policy of a service flow in the first network, where the service flow is a service flow in which a second terminal communicates with a second network by using a first terminal and a user plane network element in the first network; and the first control plane network element sends the quality of service parameter and/or the charging policy of the service flow to the user plane network element and/or the first terminal.

Communications method and apparatus

The technology of this application relates to a communication method and apparatus, to resolve a current problem that limited bandwidth resources of a single link affect quality of service. In an example embodiment, a terminal sends a first access message to an access gateway in a second core network through a first network, and sends a second access message to the access gateway through a second network, where the first access message is encapsulated by using a first IP address. Further, the access gateway requests an AMF network element to establish two communication links for the terminal. One communication link is for the terminal to access the core network through the first network, and the other communication link is for the terminal to access the core network through the second network. Through establishment of the two communication links between the terminal and the core network, bandwidth resources can be added, and the quality of service can be improved.

Embodiments of this application relate to a method for controlling service flow transmission. One example method includes: a session management network element obtains a first TMBR of a service flow transmitted in a session by using a first access technology and a guaranteed bandwidth of a first GBR service flow, where the TMBR indicates a TMBR of service flows transmitted in the session by using the first access technology. The session management network element sends first information to a data plane network element, where the first information is used by the data plane network element to determine one or more of the following information of the session: a first AMBR, a second AMBR corresponding to the first access technology, and a second TMBR. A second AMBR indicates an AMBR of a non-GBR service flow transmitted in the session by using the first access technology.

Communication method and communications apparatus

In a connection reactivation method, a connection of a PDU session established by user equipment on a N3GPP side is reactivated through communications via a 3GPP network. The user equipment accesses both the 3GPP and the N3GPP network and is originally in an idle state on the N3GPP network. An access and mobility management function entity receives a first message from a session management function entity to reactivate the PDU session connection of the user equipment. The access and mobility management function entity sends a second message to the user equipment via the 3GPP access network to instruct the user equipment to reactivate the connection of the PDU session.

Connection reactivation method, access and mobility management function entity, and system

Embodiments of the present disclosure disclose a session management method and an apparatus. The technology is specifically related to sending, by user equipment, a NAS message to an AGF, where the NAS message includes a PDU session establishment request message used to request to establish a PDU session, receiving, by the user equipment, a PDU session establishment accept message returned by a network side device, and establishing, by the user equipment, an access session with the AGF, where the access session is an access session related to the PDU session. The user equipment sends the NAS message to establish the PDU session, and establishes the access session with the AGF. Because the access session is related to the PDU session, the user equipment can map the PDU session to the access session, so that the user equipment accesses a 5G CN through a fixed network.

Example connection processing methods in a multi-access scenario and apparatus are described. One example method includes receiving a second transmission message by a session management functional entity from a mobility management functional entity. The session management functional entity determines whether establishment of a multi-access PDU session is allowed based on session subscription data of user equipment. In response to determining that the establishment of the multi-access PDU session is allowed, the session management functional entity sends an N4 session establishment or update request message to a user plane functional entity. The user plane functional entity sends a connection establishment reply message to the session management functional entity.
