Embodiments of this application provide a wireless communication method and a terminal device, to flexibly judge, according to configuration information of a network device, whether a PDCP layer entity needs to re-established, thereby preventing a re-establishment operation from being performed when the PDCP layer entity does not need to be re-established, and then reducing signaling overheads. The method includes: receiving, by a terminal device, configuration information that is used to perform mobility management on the terminal device and that is sent by a network device, where the configuration information includes indication information, and the indication information is used to configure a packet data convergence protocol PDCP layer entity; and determining, by the terminal device according to the indication information, whether to re-establish the PDCP layer entity.

This application discloses an indoor-outdoor determining-based uplink transmission method and apparatus. A terminal device or a positioning device determines whether the terminal device is located indoors or outdoors. The terminal device or the positioning device sends a first message to an access network device, where the first message includes a first information element, and the first information element indicates whether the terminal device is located indoors or outdoors. The access network device determines an access parameter of the terminal device based on the first information element, where the access parameter includes an access frequency. According to the method disclosed in embodiments of this application, uplink transmission of the terminal device in a proper frequency band is implemented, and communication interference is reduced.

Devices, systems, and methods relate to performing Internet Protocol (IP) Media Subsystem (IMS) bearer activation and radio bearer activation at different times. In some embodiments, a radio bearer is activated after the IMS bearer is activated. The radio bearer that is activated after the IMS bearer is activated may utilize a different Radio Access Technology (RAT) than an initial radio bearer. In certain instances, a device initiates activation of the radio bearer upon receiving confirmation that the IMS bearer is activated, or initiates activation of the radio bearer a predetermined period of time after initiating activation of the IMS bearer. In various embodiments, staggered IMS bearer activation and radio bearer activation can prevent collisions at components of an Evolved Packet Core (EPC).

The described technology is generally directed towards user equipment geolocation. Network measurement data associated with user equipment can be separated into static periods in which the user equipment was not moving, and moving periods in which the user equipment was moving. Static location processing can be applied to determine static locations from the static period network measurements, and moving location processing can be applied to determine moving locations from the moving period network measurements. Resulting static location information and moving location information can then be merged in order to improve the accuracy of both the static and the moving location information. The enhanced accuracy location information can be stored and used for any desired application.

A wireless device, receives, from a non-terrestrial network (NTN) node, a geographical zone configuration parameter. The wireless device determines a first zone identity of the wireless device based on the geographical zone configuration parameter and a first geographical location of the wireless device. The wireless device sends, to an access and mobility management function (AMF), a first registration request message indicating the first zone identity. The wireless device sends, to the AMF, a second registration request message indicating a second zone identity.

A wireless telecommunications device user's home telecommunications service provider determines that the user is traveling or about to travel to a foreign jurisdiction where telecommunications services are provided by a different telecommunications service provider, and proactively provides the user with options for selecting or upgrading telecommunications service and receives a selection from the user before the user leaves the home jurisdiction or ceases contact with the home service provider. When the user arrives in the foreign jurisdiction, upgraded service per the user's selection is established or soon ready to become active. The home service provider can determine the user's travel based on one or more of the user's electronic communications, calendar entries, current location, trending geographical movement, or patterns of past travels.
