Method and apparatus for broadcast service classification and notification
First Claim
1. A method of operating a device in a wireless network to receive broadcast messages as well as point to point communications, the method comprising:
- waking up the device at a preprogrammed time;
upon waking up at the preprogrammed time, receiving a first message that includes a broadcast indicator code that identifies a broadcast category or a specific broadcast;
comparing the first broadcast indicator code to one or more stored codes indicative of broadcasts subscribed to; and
in a first case that it is determined that the broadcast indicator code does not match any of the one or more stored codes going into sleep mode; and
in a second case that it is determined that the broadcast indicator code matches one of the one or more stored codes, operating the device to receive the broadcast; and
in the second case, prior to operating the device to receive the at least one broadcast;
receiving a second message indicative of a subcategory of the broadcast; and
comparing the subcategory of the broadcast to information indicative of subcategories to which the device is subscribed that is stored in the device, wherein operating the device to receive the broadcast is contingent upon a match being found between subcategory information received in the second message, and subcategory information stored in the device.

Abstract
A system (100) and methods (400, 500) for alerting user equipment devices (116) in a wireless communication network (102) to broadcasts while limiting the amount of power that must be consumed in order to ascertain if the user equipment devices (116) have subscribed to the broadcasts are provided. A communication indicator (300) that is compatible with UMTS protocols and includes, in addition to paging indicators, one or more broadcast category indicator codes (304) is provided. Devices receiving the communication indicator (300) are able to ascertain based on the broadcast category indicator codes (304) whether there is a need to expend further power in determined whether they are subscribed to the broadcast.

5. A method of operating fixed infrastructure of a communication network to transmit broadcasts, the method comprising:
-
for each wireless device among a plurality of wireless devices to which a broadcast is to be transmitted; determining a transmit time based on an ID of each of the wireless devices among the plurality of wireless devices; at each transmit time transmitting a first message that includes a broadcast indicator code that identifies a broadcast category or a specific broadcast to one or more of the plurality of wireless devices having ID'"'"'s corresponding to the transmit time; and transmitting the broadcast to the plurality of wireless devices. - View Dependent Claims (6, 7, 8, 9, 10)

11. A user equipment device for use in a wireless communication network the device comprising:
-
a transceiver; a memory for storing a program for the user equipment device; a processor coupled to the transceiver, and to the memory, wherein the processor is programmed by the program to; wake up the device at a preprogrammed time; upon waking up at the preprogrammed time, receive a first message that includes a broadcast indicator code that identifies a broadcast category or a specific broadcast; compare the broadcast indicator code to one or more stored codes; in a first case that it is determined that the broadcast indicator code does not match any of the one or more stored codes going into sleep mode; and in a second case that it is determined that the broadcast indicator code matches one of the one or more stored codes operating the device to receive the broadcast; and in the second case, prior to operating the device to receive the broadcast, receive a second message indicative of a subcategory of the broadcast; and compare the subcategory of the broadcast to information indicative of subcategories to which the device is subscribed that is stored in the device, and operate the device to receive the broadcast if a match is found between subcategory information received in the second message, and subcategory information stored in the device. - View Dependent Claims (12, 13, 14)
