System and method for a mobile station to avoid paging loss in multiple mobile networks
First Claim
1. A system for a mobile station to avoid paging loss in multiple mobile networks, the system comprising:
- a first mobile network;
a second mobile network; and
a mobile station capable of receiving paging messages from a plurality of serving cells by selecting at least a first suitable cell of the first mobile network and a second suitable cell of the second mobile network as the serving cells wherein paging occasion stagger occurs on paging occasions of the serving cells, whereby the mobile station avoids paging loss in at least the first and second mobile networks.

Abstract
A mobile station simultaneously stands by for multiple mobile networks so that the mobile station can receive paging messages from these mobile networks for responding to incoming calls. Since these mobile networks may not be synchronized, paging occasions of these mobile networks for the mobile phone may be in collision. This results in paging loss. In order to avoid paging loss, the mobile station according to the invention, during cell selection or cell reselection, selects suitable cells whose corresponding paging occasions of the mobile networks are staggered to camp on. Thus, paging messages from the mobile networks are received without paging loss.

10. A method for a mobile station to avoid paging loss in multiple mobile networks, the method comprising the steps of:
-
selecting a first suitable cell by performing cell selection for a first mobile network;
selecting a second suitable cell by performing cell selection for a second mobile network;
determining whether paging occasion stagger occurs on paging occasions of suitable cells including the first suitable cell and the second suitable cell; and
if so, camping on the suitable cells whose paging occasions are determined to be staggered, which are defined as serving cells;
whereby the mobile station avoids paging loss in the serving cells. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19)

20. A mobile station capable of avoiding paging loss in multiple mobile networks including a first mobile network and a second mobile network, the mobile station comprising:
-
means for selecting at least a first suitable cell of the first mobile network and a second suitable cell of the second mobile network to camp on during cell selection or cell reselection, wherein paging occasion stagger occurs on paging occasions for the first suitable cell and paging occasions for the second suitable cell; and
a radio frequency receiver, couple to the selecting means, to receive paging messages from at least the first and second suitable cell;
whereby the mobile station avoids paging loss in at least the first suitable cell and the second suitable cell. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28)
