Method and apparatus for delivering multimedia multicast services over wireless communication systems
First Claim
Patent Images
1. A method for delivery of multimedia broadcast and multicast service (MBMS) over a wireless system, comprising:
- a) detecting a number of subscriber units (UEs) present within a given region;
b) comparing the number of UEs detected in step (a) with a given threshold;
c) setting a flag that UEs need not track a cell identification number (ID) when the number of UEs obtained in step (a) is greater than said threshold; and
d) delivering multicast updates to the UEs employing location area/routing area (AL/RA) paging.

Abstract
A method is provided for delivery of Multimedia Broadcast and Multicast Service (MBMS) over wireless systems. The method optimizes the number of paging messages sent over the air interface in order to enhance the overall system capacity. MBMS active Mobile Station User Equipments (UEs) track their locations to the granularity of a cell based on information sent by the system.

7. A method for use by a subscriber unit (UE) in a wireless system for monitoring cell changes, comprising:
-
a) the UE activating multicasting service in a given cell; and
b) the UE thereafter listening to broadcast and paging channels whereupon when a new page message is present, the UE updates the cell ID, accesses the system and updates cell location information. - View Dependent Claims (8, 9, 10)
