Abstract
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.

The method of claim 4 wherein the region is a location area/routing area (LA/RA).
Claim 9
Independent Claim
72 words
A method for use by a subscriber unit (UE) in a wireless system for providing updates to the system, comprising: a) the UE activating multicasting service in a given cell; and b) the UE while remaining in said given cell thereafter listening to broadcast and paging channels whereupon, responsive to a new page message in said given cell, the UE updates the cell ID, accesses the system and updates cell location information.
Claim 10
Independent Claim
72 words
A method for use by a subscriber unit (UE) in a wireless system for providing updates to the system, comprising: a) the UE activating multicasting service in a given cell; and b) the UE while remaining in said given cell thereafter listening to broadcast and paging channels whereupon, responsive to a new page message in said given cell, the UE updates the cell ID, accesses the system and updates cell location information.
Claim 11
Dependent Claim
23 words
The method of claim 7 wherein the UE, upon activation of the multicasting service, reverts to an idle mode in said given cell.
Claim 12
Dependent Claim
19 words
The method of claim 7 wherein step (b) comprises returning to step (a) when no new message is present.
Claim 13
Independent Claim
95 words
A method for use by a subscriber unit (UE) in a wireless system for providing updates to the system, comprising: a) the UE activating multicasting service in a given cell; b) the UE while remaining in said given cell thereafter listening to broadcast and paging channels whereupon when a new page message is present in said given cell, the UE updates the cell ID, accesses the system and updates cell location information; and wherein, at step (b) the UE further identifies a new cell ID and track cell ID when no new message is present.
Claim 14
Independent Claim
95 words
A method for use by a subscriber unit (UE) in a wireless system for providing updates to the system, comprising: a) the UE activating multicasting service in a given cell; b) the UE while remaining in said given cell thereafter listening to broadcast and paging channels whereupon when a new page message is present in said given cell, the UE updates the cell ID, accesses the system and updates cell location information; and wherein, at step (b) the UE further identifies a new cell ID and track cell ID when no new message is present.
