Cell reselection methods based on tracking area for cellular systems

摘要

In a method of assigning cell reselection parameters to be utilized by user devices served by a first cell associated with a first tracking area, that a first signal frequency is associated with a second tracking area different than the first tracking area is determined. Based on a determination that the first signal frequency is associated with the second tracking area different than the first tracking area, a first set of one or more reselection parameters is assigned to the first signal frequency.

1. A method for performing cell reselection in a user device served by a first cell, the method comprising:
receiving a first set of one or more reselection parameters, wherein the first set of one or more reselection parameters includes (i) a tracking area identifier associated with a second cell and (ii) a priority of a signal frequency utilized by the second cell, wherein the second cell neighbors the first cell; comparing the tracking area identifier associated with the second cell to a tracking area identifier associated with the first cell; comparing the priority of the signal frequency utilized by the neighbor cell to a priority of a signal frequency utilized by the current cell; determining a second set of one or more reselection parameters associated with the second cell; and determining whether to reselect the second cell based on (i) a comparison of the tracking area identifier associated with the second cell to the tracking area identifier associated with the first cell, (ii) a comparison of the priority of the signal frequency utilized by the second cell to the priority of the signal frequency utilized by the first cell, (iii) the first set of one or more reselection parameters, (iv) the second set of one or more reselection parameters, and (v) a set of one or more reselection criteria, including
selecting a threshold based on (i) the comparison of the tracking area identifier associated with the second cell to the tracking area identifier associated with the first cell, and (ii) a comparison of the priority of the signal frequency utilized by the second cell to the priority of the signal frequency utilized by the first cell, andcomparing a reselection parameter of the second set to the selected threshold.
