Problems solved by technology

Because, on the one hand, the location area is too small to increase the probability of location update; on the other hand, the system needs to manage a large number of location area identifiers, which increases the difficulty of maintenance

Embodiment Construction

[0038] The core idea of ​​the embodiments of the present invention is that when the terminal enters the idle mode, it can select other cells to camp on. The specific method is: when it is judged that the terminal enters the idle mode, directly select the second cell (macro cell) corresponding to the first cell (micro cell) as the camping cell, and the corresponding second cell is the second cell covering the first cell . Thereafter, as long as the terminal moves within the location area to which the second cell belongs, it does not need to update its location. When the paging control center on the network side initiates paging, it only performs paging in the location area to which the second cell belongs. The paging message is only sent in the second cell, but not in the first cell. Certainly, the terminal must also keep waiting for the paging message in the second cell.

[0039] In a layered network, the second cell (macro cell) is mainly used for continuous coverage in a ...

Abstract

The invention example relates to the communication field and discloses a method to select a district. The method includes judging whether a terminal in a first district enters into a free mode or not; if so, selecting a second district covered on the first district to be a staying district. The invention example also discloses a paging control center and network system of a terminal and network. Adopting the method, system and relevant devices can reduce unnecessary sending of paging information, reduce the station location markers needed managing by system and lighten the system maintenance intensity.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for selecting a cell, a network system and related equipment. Background technique [0002] In cellular radio communication systems, a geographical area is divided into cells. At a certain moment, the terminal communicates only in one or a few cells. The terminal has multiple working modes. When the terminal has no business for a long time, in order to save power, it usually enters the idle mode. A typical process for a terminal to enter idle mode consists of two steps: 1. The terminal sends a message to the network side, requesting to enter the idle mode; 2. The network side sends a message to the terminal to confirm that the terminal has entered the idle mode. The terminal in the idle mode usually does not receive or send, but only periodically receives paging messages in the cell where it resides at the agreed time, and then decides whether to exit the idle mode accordin...
