Abstract
Abstract A selective call device (130) has a receiver (204) for receiving a selective call signal including an address (312) and a topic sub-address (504) indicative of a subscribed information, a processor (212, 214) for correlating the address (312) in the selective call signal to determine when the selective call signal is directed thereto, a decoder (212), in response to the processor (212, 214) determining that the selective call signal is directed thereto, for decoding the topic sub-address (504) to determine when the selective call signal includes the subscribed information, and a battery saver, coupled to the receiver (204), for initiating battery saving when the address (312) does not correlate with a predetermined address of the selective call device (130) and for initiating battery saving when the topic sub-address (504) is absent from the selective call signal.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
126 words
A selective call device, comprising: a receiver for receiving a selective call signal including an address and a topic sub-address indicative of a subscribed information; a processor for correlating the address in the selective call signal to determine when the selective call signal is directed thereto; a decoder, in response to the processor determining that the selective call signal is directed thereto, for decoding the topic sub-address indicative of the subscribed information to be received; and a battery saver, coupled to the receiver, for initiating battery saving when the address does not correlate with a predetermined address of the selective call device and for initiating battery saving when the selective call signals include the address and the topic sub-address is absent from the selective call signal.
Claim 2
Dependent Claim
126 words
A selective call device, comprising: a receiver for receiving a selective call signal including an address and a topic sub-address indicative of a subscribed information; a processor for correlating the address in the selective call signal to determine when the selective call signal is directed thereto; a decoder, in response to the processor determining that the selective call signal is directed thereto, for decoding the topic sub-address indicative of the subscribed information to be received; and a battery saver, coupled to the receiver, for initiating battery saving when the address does not correlate with a predetermined address of the selective call device and for initiating battery saving when the selective call signals include the address and the topic sub-address is absent from the selective call signal.
Claim 3
Dependent Claim
26 words
The selective call device according to claim 1 wherein the decoder decodes the selective call signal for an information service sub-address associated with the subscribed information.
Claim 4
Dependent Claim
22 words
The selective call device according to claim 2 wherein the battery saver initiates battery saving when the information service sub-address is absent.
Claim 5
Dependent Claim
31 words
The selective call device according to claim 2 wherein the decoder decodes the information service sub-address of the subscribed information in response to decoding the topic sub-address of the subscribed information.
Claim 6
Independent Claim
71 words
A method, comprising the steps of: receiving a communication signal comprising an address and a topic sub-address indicative of a subscribed information service; initiating a first battery saving when the address is not received; decoding the communication signal for the topic sub-address in response to a receipt of the address; and initiating a second battery saving when the topic sub-address is not decoded indicating an absence of the subscribed information service.
Claim 7
Independent Claim
71 words
A method, comprising the steps of: receiving a communication signal comprising an address and a topic sub-address indicative of a subscribed information service; initiating a first battery saving when the address is not received; decoding the communication signal for the topic sub-address in response to a receipt of the address; and initiating a second battery saving when the topic sub-address is not decoded indicating an absence of the subscribed information service.
Claim 8
Dependent Claim
53 words
The method according to claim 5 wherein the step of decoding further comprising the steps of: decoding the communication signal for an information service sub-address indicative of the subscribed information service in response to decoding the topic sub-address; and initiating a third battery saving upon a failure to decode the information service sub-address.
Claim 9
Dependent Claim
27 words
The method according to claim 5 wherein the step of decoding further decodes the communication signal for a command number indicative of a range of topic sub-addresses.
Claim 10
Dependent Claim
42 words
The method according to claim 7 wherein the step of initiating initiates the second battery saving when the topic sub-address of the subscribed information service is not within the range of topic sub-addresses comprising a topic begin sub-address and an offset therefrom.
Claim 11
Dependent Claim
43 words
The method according to claim 7 wherein the step of initiating initiates the second battery saving when the topic sub-address of the subscribed information service is not within the range of topic sub-addresses comprising a topic begin sub-address and a topic end sub-address.
Claim 12
Dependent Claim
31 words
The method according to claim 5 wherein the step of decoding further decodes the communication signal for a command number indicative of a range or an itemized list of topic sub-addresses.
