Method for wireless communication, core network entity and user equipment

Abstract

The present invention provides a method and device for wireless communication. The method is applied in a communication system. The communication system includes a user equipment UE, a radio access network RAN, a first core network entity, and at least one network slice. The method includes: a first A core network entity establishes a signaling connection with the UE; the first core network entity receives network slice information and non-access stratum NAS messages sent by the UE through the signaling connection; the first core network entity selects from at least one network slice according to the network slice information Determine the target network slice, wherein the target network slice includes the second core network entity, and the UE performs NAS communication with the second core network entity through the RAN and the first core network entity; the first core network entity sends the second core network entity The entity sends the NAS message. Therefore, the amount of signaling in the communication process can be reduced, and the efficiency of network management and maintenance can be improved.

Description

[0001] This application claims priority to a PCT patent application filed with the China Patent Office on May 30, 2016, with application number PCT / CN2016 / 083887, and the title of the invention is "Method and Device for Wireless Communication", the entire contents of which are incorporated herein by reference In this application. technical field [0002] Embodiments of the present invention relate to the communication field, and more specifically, to a method and device for wireless communication. Background technique [0003] In order to meet service requirements in various scenarios, a mobile communication system divides a physical network into multiple virtual logical networks, and these virtual logical networks are called network slicing (Network Slicing). That is, the network can be composed of multiple network slices. A specific network slice can be defined as a collection of logical network functional entities that support the communication service requirements of a s...

Problems solved by technology

[0004] In the existing standard scheme of the 3rd Generation Partnership Project (referred to as "3GPP"), the scenario where the UE accesses multiple Network Slicings at the same time is supported. During the communication process where the UE accesses multiple Network Slicings simultaneously, the network There are many signalings in the network, which leads to the waste of network resources and affects the user's communication experience
