Problems solved by technology

When the mobile terminal is far away from the base station, the received signal will gradually decrease, causing the signal reception quality of services such as calls to deteriorate
Moreover, when the received signal further deteriorates, it will cause the uplink / downlink wireless link to lose synchronization, which will lead to call drop

Embodiment approach

[0030] figure 1 An embodiment of the cell update method of the mobile communication system of the present invention is shown, which includes:

[0031] Execute step s1 to detect the neighbor cell configuration of the current serving cell;

[0032] Execute step s2, judge whether the current serving cell is configured with neighboring cells according to the detection result; if yes, end the cell update process; if not, go to step s3;

[0033] Execute step s3 to obtain the power-related measurement results of the current serving cell;

[0034] Execute step s4 to determine whether the power-related measurement result is less than the search threshold; if so, go to step s5; Monitoring of the power related measurement results of the serving cell;

[0035] Execute step s5, search for switchable cells existing in the surrounding area, the power correlation value of the switchable cell is greater than the switching threshold value, and the system message can be correctly received in ...

Abstract

The invention provides a cell updating method of a mobile communication system and a mobile terminal. The cell updating method of the mobile communication system comprises the following steps: detecting the configuration in neighboring cells of the existing service cell; acquiring related power measurement results when the existing service cell is not configured with neighboring cells; searching for surrounding switchable cells when the related power measurement results of the existing service cell are less than the search threshold value, wherein the related power value of the switchable cell is greater than the switchable threshold value, and the system information can be accurately received in the switchable cell; and conducting cell updating in the switchable cell. The cell updating method and the mobile terminal in the invention improve the problem of stepping out of the wireless uplink/downlink, thus lowering the dropped call rate of the isolated cells.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a cell update method and a mobile terminal of a mobile communication system. Background technique [0002] In a wireless cellular network, a mobile terminal will initiate a cell update process or similar processes based on various reasons. There are multiple reasons for the cell update process, for example, the terminal notifies the network that it is in a standby state, its location changes, and so on. For example, in a GSM / GPRS network, a mobile terminal periodically sends a location update request (Location Update Request) message to the network in order to update its own location information. In Time Division-Synchronous Code Division Multiple Access (TD-SCDMA, Time Division-Synchronous Code Division Multiple Access) or Wideband Code Division Multiple Access (WCDMA, Wideband Code Division Multiple Access) network, or even in a long-term evolution (LTE) system, mobile A...
