Problems solved by technology

[0003] Currently, 5G technology requires the base station to know the notification area where the UE in the inactive state is located. However, due to the mobile nature of the UE, the notification area where the UE is located may change. Therefore, when When the notification area where the UE is located changes, the notification area needs to be updated

Embodiment Construction

[0129] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

[0130] Before explaining and describing the embodiments of the present disclosure in detail, the application scenarios of the embodiments of the present disclosure will be introduced first. At present, when the UE is in the inactive state, the base station needs to know the notification area where the UE is located, but the UE has mobile characteristics, which may cause the notificatio...

Abstract

The present disclosure relates to a method for updating a notification area, and relates to the field of wireless communications. The method comprises: in an inactive state, determining, based on a stored cell identifier list, a first cell identifier for currently updating a notification area, multiple cell identifiers and the current signal strength of a cell corresponding to each cell identifier being stored in the cell identifier list; sending a first notification area updating request to a base station, the first notification area updating request carrying the first cell identifier and a base station identifier of the access base station when a notification area is updated on the previous time; and receiving an updating permission notification sent by the base station, and updating a notification area into a cell corresponding to the first cell identifier. In the present disclosure, in an inactive state, the notification area is updated into the cell corresponding to the first cell identifier; and when the notification area where a UE in the inactive state is located is changed, an operation of updating the notification area can be performed.

Description

technical field [0001] The present disclosure relates to the field of wireless communication, and in particular to a method and device for updating a notification area. Background technique [0002] With the development of wireless communication technology, 5G (fifth-generation, fifth-generation mobile phone system) technology has also attracted more and more attention. Among them, the 5G technology introduces an inactive state. For a UE (User Equipment, user equipment) in the inactive state, the UE can interact with the base station in a small data packet. The small data packet refers to It is a data packet whose size is smaller than the preset size, that is, the UE can directly send and receive data packets in the inactive state without entering the connected state, thereby reducing the power consumption of the UE and saving Signaling overhead. [0003] Currently, 5G technology requires the base station to know the notification area where the UE in the inactive state is ...
