Patent ID: 7299045

Claim:
A cell reselection method for a mobile subscriber, the mobile subscribe receiving signals from a serving cell and a neighboring cell, the method comprising: (a) collecting a first C1 parameter and a first C2 parameter of the serving cell corresponding to the mobile subscriber, and a second C2 parameter of the neighboring cell corresponding to the mobile subscriber; (b) comparing the first C1 parameter to a predetermined value; (c) if the first C1 parameter is smaller than the predetermined value, comparing a second location area code (LAC) of the neighboring cell to a first LAC of the serving cell; (d) if the second LAC and the first LAC are the same, comparing the second C2 parameter to the first C2 parameter, and if the second C2 parameter remains larger than the first C2 parameter for a first predetermined period, executing cell switching from the serving cell to the neighboring cell for the mobile subscriber; (e) if the second LAC and the first LAC are not the same, comparing the second C2 parameter to a first parameter, and if the second C2 parameter remains larger than the first parameter for a second predetermined period, executing cell reselection from the serving cell to the neighboring cell for the mobile subscriber, wherein the first parameter is the sum of the first C2 parameter and a first threshold value; and (f) if the first C1 parameter is larger than the predetermined value, comparing the second C2 parameter to the first C2 parameter, and if the second C2 parameter remains larger than the second parameter for a third predetermined period, executing cell switching from the serving cell to the neighboring cell for the mobile subscriber, wherein the second parameter is the sum of the first C2 parameter and a second threshold value.
