Title:
METHODS AND SYSTEM FOR CARRYING OUT A HANDOVER OF A MOBILE COMMUNICATION DEVICE BETWEEN DIFFERENT ACCESS NETWORKS
Document Type and Number:
WIPO Patent Application WO/2019/169612
Kind Code:
A1
Abstract:
A method of handing over a mobile communication device from a first access network to a second access network (in one implementation) is as follows. In response to a protocol data unit session update request, a first computing device (e.g., an AMF) receives an identifier of a protocol data unit session and network slice information regarding a network slice to be used by the mobile communication device to communicate on the second access network using the protocol data unit session. The first computing device uses the network slice information to select a network slice instance and to select a second computing device (e.g., another AMF) within the network slice instance. The first computing device transmits, to the second computing device, a relocation request that includes the network slice information and the identifier of the protocol data unit session.
