Example Embodiment

[0018] The following briefly introduces some concepts involved in the embodiments of the present application.

[0019] In the description of this application, unless otherwise specified, " / " means "or". For example, A / B can mean A or B. "And / or" in this article is only an association relationship that describes associated objects, which means that there can be three relationships, for example, A and / or B, which can mean: A alone exists, A and B exist at the same time, and B exists alone These three situations. In addition, "at least one" means one or more, and "plurality" means two or more. The words "first" and "second" do not limit the quantity and order of execution, and the words "first" and "second" do not limit the difference.

[0020] In the description of this application, the user terminal (target terminal, first target terminal) can be a user equipment (UE), such as a mobile phone, a computer, a cellular phone, a cordless phone, and a session initiation protocol (sessio...

Abstract

The invention discloses a method and a device for determining a routing selection policy (URSP), relates to the field of communication, and ensures the continuity of the URSP of a user terminal on different networks. The method comprises the following steps: receiving a route selection request sent by a user terminal; determining a routing selection strategy URSP corresponding to the user terminalaccording to the routing selection request, wherein the URSP includes: an attribute table of a plurality of routing descriptors (RSDs), the attribute table of each RSD at least comprises a radio access technology RAT type, and the RAT type is at least used for indicating that the attribute table of the RSD to which the RAT type belongs is only suitable for the network of the RAT type; and sendingthe URSP to the user terminal.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for determining URSP. Background technique [0002] Currently, in the third generation partnership project (third generation partnership project, 3GPP), the core network of the fifth generation mobile communication technology (the 5th generation mobile communication, 5G) defines a user equipment routing selection policy (user equipment routing selection policy, URSP), URSP focuses on defining service-level configuration and management strategies, and provides flexible configuration and management means for functions such as network slicing, service and session continuity defined by the 5G core network. [0003] However, the current URSP is only defined for the 5G system, that is, the current URSP can only take effect when the user accesses the 5G core network, which means that once the user moves out of the 5G coverage area, it will switch to the fourth gener...
