Paging a mobile entity in mobile networks

摘要

The present invention relates to a method for paging, by a network mobility management unit, a mobile entity in a cellular network. The method includes receiving plural location reports, each respectively including an indicator indicating a position of the mobile entity, determining whether indicators included in at least two successive location reports indicate a position in a same second area, selectively setting paging control information for the mobile entity to a first area mode or to a second area mode based on said determining, paging the mobile entity in a first area of the cellular network when the paging control information is set to the first area mode, or paging the mobile entity in said second area when the paging control information is set to the second area mode. The second area is a sub-area of the first area.

1. A method for paging, by a network mobility management unit, a mobile entity in a cellular network, the method comprising:
receiving plural location reports, each respectively including an indicator indicating a position of the mobile entity, determining whether indicators included in at least two successive location reports indicate a position in a same second area, selectively setting paging control information for the mobile entity to a first area mode or to a second area mode based on said determining, paging the mobile entity across a first area of the cellular network when the paging control information is set to the first area mode, and alternately paging the mobile entity across said second area when the paging control information is set to the second area mode, wherein said second area is a sub-area of the first area, establishing whether the mobile entity is successfully paged while the paging control information is set to the first area mode, wherein, in response to establishing that the mobile entity is successfully paged for a predefined number of times in succession and determining during paging for the predefined number of times that the indicators in the location reports indicate positions in the same second area, setting the paging control information to the second area mode, and wherein, when the paging control information is set to the first area mode, a counter is adjusted towards a threshold in response to establishing that paging has been successful, and the counter is adjusted away from the threshold in response to establishing that paging has been unsuccessful or determining that indicators included in at least two successive location reports indicate positions in different second areas, wherein the paging control information is set to the second area mode responsive to the counter reaching the threshold.
