Problems solved by technology

[0013] 1) During the process of reading system messages, since the total duration of the user equipment UE being unable to receive paging messages is the total time of the above two steps (4) and step (5), the user equipment UE is unable to receive paging time for the network Long, resulting in a high probability of not being connected;
[0014] 2) The existing process leads to a long time for updating the location of the user equipment UE, which is not conducive to precise network paging and wastes network resources

Embodiment Construction

[0090] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0091] The core idea of ​​the embodiment of the present invention is to implement the process of cross-LAC reselection in the TD network by the UE. When the terminal reads SIB1, SIB3, SIB5, SIB7 and other system messages, it submits them to the NAS layer to complete the non-access layer. In the process, the location area is updated in time. After the non-access stratum process is completed, the UE chooses to read the remaining SIB messages according to the current state. This reduces the time taken by the UE to read other system messages that are not related to location update and paging acceptance, and is also conducive to precise paging on the network side, reducing the probability of the network sending paging messages simultane...

Abstract

The invention provides a user equipment location area updating method and a device. The user equipment location area updating method includes a first step of obtaining a candidate cell listing, a second step of reading a first system message of candidate cells in the candidate cell listing in sequence, and confirming reselected cells of user equipment (UE) according to the first system message which is the required system message of the candidate cell, a third step of obtaining the position area information of the reselected cells, a fourth step of obtaining the position area information of the UE and judging whether the position area information of the UE accords with the position area information of the reselected cells, and a fifth step of updating the position area information of the UE if the position area information of the UE does not accord with the position area information of the reselected cells. The user equipment location area updating method and the device can reduce reselection time delay of the UE and improve the system connection rate.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method for updating a location area of ​​a user equipment, and a device for updating a location area of ​​a user equipment. Background technique [0002] During the standby process, the user equipment UE may leave the coverage of the current cell and enter a new cell. At this time, the user equipment UE will leave the original cell and determine a camping relationship with the new cell. In a certain state, the user equipment UE may use a cell reselection mechanism to select a new cell. Cell reselection is a must-have function of a mobile communication system. It is an important part of RRM (Radio Resource Management, radio resource management). The cell reselection of UE (User Equipment, user equipment) in idle mode is to update the cell where UE resides in time. , so that the UE resides in an ideal cell, thereby ensuring that the UE can correctly receive syst...
