US 11,082,894 B2 · System and method for enhanced session management in nextgen mobile core networks

Abstract

The present disclosure relates to an enhanced session model capable of managing the configuration and the usage of a single packet data unit session, which is an association between a user equipment and a packet data network entity and is composed of multiple transmission bearers between the access network and the core network. The latter comprises a session type manager entity adapted to control the connectivity of these transmission bearers whose assignment is either individual or shared, multiple user plane function entities, a session type database and a control plane function entity. The latter can be functionally separate from the session type manager entity or extended with its functionalities. The user equipment and the user plane function entities are individually extended with the functionalities of, respectively, a user session type extension entity and user plane session type extension entities, which all comprise a respective mapping table dedicated to the assignment.

Dependent claims

A device in a core network (CN) of a mobile communication network, the mobile communication network including an access network (AN) and the CN, the device comprising:

one or more processors coupled to a memory that stores a program, which, when executed by the one or more processors, causes the one or more processors to:
control a connectivity of multiple transmission bearers over at least two access points (APs) of a same AN technology and the CN, based on a selective assignment of the multiple transmission bearers, wherein the selective assignment of the multiple transmission bearers is amongst at least two transmission bearers from the at least two APs of the same AN technology and at least one transmission bearer of the CN, the at least two transmission bearers from the at least two APs of the same AN technology and the at least one transmission bearer of the CN belonging to a single packet data unit (PDU) session;
and
provide information on an operation mode of a PDU session to be used by a user equipment (UE), the operation mode of the PDU session defining PDU session configuration information for a transmission of a data traffic over the at least two transmission bearers from the at least two APs of the same AN technology and the at least one transmission bearer of the CN.

1 more element

A method within a mobile communication network including an access network (AN) and a core network (CN), the method comprising:

controlling, at a device in the CN, a connectivity of multiple transmission bearers over at least two access points (APs) of a same AN technology and the CN, based on a selective assignment of the multiple transmission bearers, wherein the selective assignment of the multiple transmission bearers is amongst at least two transmission bearers from the at least two APs of the same AN technology and at least one transmission bearer of the CN, the at least two transmission bearers from the at least two APs of the same AN technology and the at least one transmission bearer of the CN belonging to a single packet data unit (PDU) session;
and
providing, at the device in the CN, information on an operation mode of a PDU session to be used by a user equipment (UE), the operation mode of the PDU session defining PDU session configuration information for a transmission of a data traffic over the at least two transmission bearers from the at least two APs of the same AN technology and the at least one transmission bearer of the CN.
