Embodiment Construction

[0045] In order to better understand the technical solutions provided by the embodiments of the present application, the technical terms involved in the embodiments of the present application are first introduced.

[0046] 1. Network architecture of 5G system

[0047] See figure 1 , is a schematic diagram of the network architecture of the 5G system, where the network architecture includes a UE, an access network (access network, AN) device, a core network element, and a DN.

[0048] The access network device may also be a radio access network (radio access network, RAN) device. The access network device may include a base station (base station, BS), which may be a device deployed in a wireless access network and capable of wirelessly communicating with a terminal device. The base station may have various forms, such as a macro base station, a micro base station, a relay station, and an access point. Exemplarily, the access network device involved in this embodiment of the ...

Abstract

The invention provides a wireless connection establishment method and a communication device, which can be applied to an establishment process of a wireless connection of a PDU (Protocol Data Unit) session. The method may comprise: an access management network element receiving a first establishment request from a user equipment, the first establishment request being used for requesting to establish a first wireless connection; determining that a second wireless connection with a permanent online attribute is not established; and triggering the establishment of the first wireless connection, and triggering the establishment of the second wireless connection. By adopting the method and the device, the establishment process of a plurality of wireless connections can be simplified, so that the time delay is reduced.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular, to a method and apparatus for establishing a wireless connection. Background technique [0002] Fifth generation (5 th A wireless connection in a -generation, 5G) communication system may be a wireless connection of a protocol data unit (PDU) session. A PDU session refers to a process of communication between a user equipment (user equipment, UE) and a data network (data network, DN), and the wireless connection of the PDU session refers to a data transmission channel between the UE and the DN. For the access stratum (SA), the wireless connection of the PDU session may include data transmission channels between the UE and the access network and between the access network and the user plane function (UPF) network element . [0003] The 5G system establishes the wireless connection of the PDU session on demand. For example, the UE establishes the wireless co...
