Abstract: The present application relates to the technology of communications. Disclosed are a method and device for shunting IP streams during 3GPP access switching; after having received a command for 3GPP access switching transmitted by a source 3GPP access device, a user equipment (UE) determines the IP streams to be transferred, and then performs 3GPP access switching and IP stream transferring at the same time, thus improving IP stream transferring efficiency. In addition, the IP streams to be transferred contain an IP stream capable of being transmitted via WLAN access after a target 3GPP access device fails to allocate resources to a bearers for transmitting the IP stream, thereby avoiding service interruption due to bearer loss, and thus improving the QoS ensurance for the service.

Abstract: A method and an apparatus for session reestablishment, an Access and Mobility Management Function entity AMF, a Session Management Function entity SMF and a terminal are provided. The method includes: AMF obtaining a Non-Access Stratum NAS message transmitted by a terminal, where the NAS message is to request to establish a new packet data unit PDU session connected to a same data network as an initial PDU session, and the NAS message carries first identification information of the initial PDU session and second identification information of the new PDU session assigned by the terminal; and transmitting a session management request to SMF corresponding to the first identification information. The session management request carries the first identification information and the second identification information, and the session management request is to cause the SMF to establish the new PDU session based on the first identification information and the second identification information.

Abstract: The present disclosure provides a routing method and a routing device. The routing method includes: receiving, by an AMF, a first message from an (R)AN, the first message including session-related information and routing information associated with the session-related information; and routing, by the AMF, the session-related information to a relevant SMF in accordance with the routing information. According to the present disclosure, it is able to correctly route the session-related information between the (R)AN and the SMF.

Abstract: A network access method, a relevant device and a system are provided. The network access method includes: storing, by a UE, identifier information of a network node that the UE accesses via a first RAN; and transmitting, by the UE, a connection establishment request comprising the identifier information of the network node to a second RAN while the UE maintains the connection to the first RAN, to enable the second RAN to select the network node for the UE as a network node that the UE accesses via the second RAN.
