The embodiment of the present invention provides a method for triggering a user equipment to report information, or a method for triggering a user equipment to initiate an information update process, which is applied to a device side (for example, a user equipment) that triggers a user equipment reporting information/initiation information update process.

FIG. 2 is a flowchart of a method for triggering user equipment to report information according to Embodiment 1 of the present invention. As shown in FIG. 2, the method includes:

Step 201: The user equipment in the inactive state moves to a cell that is not in the area to which the user equipment belongs, or does not change in the area within a predetermined time, or moves to a new one via a radio access technology (RAT, Radio Access Technology) When the radio (NR) cell is in the inactive state, the user equipment is triggered to report related information to the network side, where the related information includes the identifier of the user equipment and the cell identifier.

In this embodiment, the cell identifier included in the related information may be a cell identifier of a cell where the user equipment is located when the information update is last completed.

In this embodiment, the area to which the user equipment belongs may be a RAN-based notification area, and the area may include one or more cells.

In this embodiment, the network side may configure its area for the user equipment in advance, and the user equipment pre-stores the area-related configuration information configured by the network side. For example, the configuration information may be represented by a cell identifier (Cell ID), such that the configuration information may include a cell identifier, such as a cell ID list, and the list may include one or more cell identifiers. Alternatively, the configuration information is represented by an area ID (referred to as area configuration information). In this way, the configuration information includes an area identifier, such as a list of area identifiers. (Area ID list), the list may include one or more area identifiers. In this case, the configuration information may further include a cell identifier list corresponding to each area, but the cell identifier list is optional.

When the cell identifier is not included in the configured cell identifier list, the location of the user equipment may be determined to be changed based on the area granularity; otherwise, the location may be determined. The location of the user equipment does not change based on the granularity of the area.

For example, when the area identifier is used to indicate the area, the user equipment can receive the network device of the cell in which the user is located, for example, the area identifier (Area ID) of the area to which the user equipment of the user equipment is broadcast, such as the base station (eg, gNB); The device compares the area identifier with the configured configuration information (area identifier list). When the area identifier is not included in the configured area identifier list, the device determines that the location of the user equipment changes based on the area granularity; otherwise It can be determined that the location of the user equipment has not changed based on the granularity of the area. In an embodiment, a period-updated area update timer, such as a T3xx timer, may be triggered to report the related information when the timer expires and the area to which the user equipment belongs does not change, and determine whether the user equipment belongs to the area. The method of change is as described above and will not be described here.
