Patent ID: 7949337

Claim:
A cell reselection method in which a host system provides a mobile terminal with information about a most suitable cell on which to camp, the method comprising: performing, by the mobile terminal, a cell selection by camping on a cell which has the strongest receive signal strength among a plurality of neighboring cells after measuring signal strength of the plurality of neighboring cells; transmitting, by the mobile terminal, registration information to the host system, wherein the host system maintains a list of cells that are suitable for the mobile terminal to camp on based on the registration information provided by the mobile terminal, the list of cells including suitable cells and unsuitable cells, wherein the registration information comprises information about at least terminal specification, a service type or a data transfer rate associated with the mobile terminal, wherein the host system retrieves moving information of the mobile terminal according to changes in the registration information of the mobile terminal at predetermined time intervals, wherein the host system, in response to retrieving the moving information, updates the list of cells such that a most suitable cell for the mobile terminal is identifiable when a cell reselection request is received from the mobile terminal; scanning, by the mobile terminal, one or more cells neighboring the cell on which the mobile terminal is camping to determine respective signal strength of one or more neighboring cells when the mobile terminal is moved; transmitting, by the mobile terminal, the cell reselection request comprising identity and signal strength data for the neighboring cells to the host system, in response to determining that signal strength of the cell on which the mobile terminal is camping has fallen below a threshold; receiving, by the mobile terminal, a list comprising identity data for a target cell on which the mobile terminal is to camp from the host system, wherein the host system selects the most suitable cell for the mobile terminal as the target cell based on the updated list of cells.
