Abstract: The present disclosure provides an offloading policy negotiation method and apparatus, so as to resolve problems in the prior art that a method for initiating data flow switching by UE has low applicability, and that a network side cannot control and manage the UE, and that user experience is reduced. The method includes: sending, by a first device, an offloading policy to a second device, where the offloading policy includes a default access indication and a routing rule; and receiving and storing, by the first device, an acknowledged offloading policy returned for the offloading policy by the second device, and transmitting a data flow based on the acknowledged offloading policy.

Abstract: 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.

Abstract: A network access control method and an apparatus are disclosed. The method includes controlling, by a first network device if determining that a terminal device already establishes a second data connection to a second network, the terminal device to stop establishment of a first data connection to a first network, or controlling the terminal device to end the second data connection, to smoothly establish a first data connection. In this way, it can be ensured that a data connection exists between the terminal device and one network, and it can be ensured that the terminal device can normally transmit data.

Abstract: Sending an authentication request message to an authentication device, receiving an authentication response message sent by the authentication device, where the authentication response message includes a trust relationship information element which is used for indicating a trust relationship of a current access, and establishing an S2c tunnel security association according to the trust relationship of the current access. The trust relationship when the non-3GPP access side accesses the EPS network may be obtained, thereby ensuring establishment of a correct S2c tunnel security data channel.
Abstract translation: 向认证装置发送认证请求消息，接收认证装置发送的认证响应消息，认证响应消息中包含用于指示当前接入信任关系的信任关系信息单元，建立S2c隧道 安全关联根据当前访问的信任关系。 可以获得非3GPP接入侧访问EPS网络的信任关系，从而确保建立正确的S2c隧道安全数据信道。

Abstract: Embodiments of this application provide a communication method, apparatus, and system. The method includes: A first user plane network element controls, based on a first AMBR, one or more data flows that are in data flows of a first session and that are transmitted on a data transmission channel of a first access technology; and a UL CL controls, based on a second AMBR, data flows that are in the data flows of the first session and that are transmitted on data transmission channels of a second access technology. This implements control on the data flows of the session and helps improve communication quality.

Abstract: The present disclosure relates to paging methods and apparatus. One example method is applied to a first access network device. The first access network device belongs to a first network, a second access network device belongs to a second network, and the first network may be different from the second network. When UE accesses the first network and downlink data of the second network arrives, the UE may receive the data of the second network. The first access network device receives downlink data of a terminal from a first core network device, where the first core network device belongs to the first network.
