    Abstract: A Session Management Function (SMF) provides session and service continuity for a User Equipment (UE) transitioning between User Plane Functions (UPFs). The SMF establishes a first session between the first UPF and the UE using a first network address. The SMF determines that the UE transitions to the second UPF and establishes a second session between the second UPF and the UE using a second network address for new flows on the second session. The SMF queries the first UPF to determine any ongoing flows in the first session. The first UPF forwards packets in the ongoing flow(s) to the UE via the second UPF. The second UPF forwards packets in the ongoing flow(s) to the first UPF with the first network address. The SMF directs the second UPF to replace the first network address with the second network address in packets of a new flow for the UE.

    Abstract: A method is performed by a mobility management entity (MME) in a network. Responsive to a session request from user equipment (UE), the MME initiates a session request procedure that includes: selecting a control plane serving gateway (SGW) and a user plane packet data network gateway (PGW) to establish a session for the UE; and receiving from the control plane SGW a session response to the session request, the session response including an identifier of the user plane PGW. After the session is established, responsive to a relocation request from the UE, the MME initiates a relocation procedure that includes: selecting a new control plane SGW; and sending to the new control plane SGW a new session request with the identifier of the user plane PGW, to cause the new control plane SGW to perform selecting the user plane PGW for the session in the relocation procedure.

    Abstract: Provided herein are techniques to facilitate network slice service continuity in a mobile network environment. In one example, a method may include for a registration request involving a user equipment (UE), obtaining, by an Access and Mobility Management Function (AMF), subscription information identifying primary network slices backup network slices to which the UE is subscribed in which each of the primary network slices and the backup network slices are active network slices capable of actively handling sessions for multiple UEs. The method may further include determining whether there is registration capacity for the UE with each of the network slices with which the UE is allowed registration. Based on the determining that there is registration capacity for registration of the UE, the AMF can transmit a registration response to the UE that indicating registration with the first primary network slice and the first backup network slice is accepted.
