Abstract
Abstract A method for efficiently paging a mobile phone in a radio communication system having a plurality of mobile phones is disclosed. A first paging signal is transmitted for a mobile phone on a first try channel. If the mobile phone does not acknowledge the first paging signal within a predetermined period of time, the call is transferred to at least a second try channel. A second paging signal is then transmitted for the first mobile phone on at least the second channel.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
98 words
A method for efficiently paging a mobile phone in a radio telephone system having a plurality of mobile phones, comprising the steps of: transmitting a first paging signal for a first mobile phone on a first calling channel; transferring the call to at least a second calling channel when said first mobile phone does not acknowledge said first paging signal within a predetermined period of time; and transmitting a second paging signal for said first mobile phone on at least said second calling channel, wherein said second channel employs more error correction coding than the first calling channel.
Claim 2
Independent Claim
98 words
A method for efficiently paging a mobile phone in a radio telephone system having a plurality of mobile phones, comprising the steps of: transmitting a first paging signal for a first mobile phone on a first calling channel; transferring the call to at least a second calling channel when said first mobile phone does not acknowledge said first paging signal within a predetermined period of time; and transmitting a second paging signal for said first mobile phone on at least said second calling channel, wherein said second channel employs more error correction coding than the first calling channel.
Claim 3
Dependent Claim
25 words
A method for efficiently paging a mobile phone according to claim 1, wherein said first paging signal contains a minimum amount of error correction coding.
Claim 4
Dependent Claim
23 words
A method for efficiently paging a mobile phone according to claim 1, wherein said first paging signal does not include error correction coding.
Claim 5
Dependent Claim
36 words
A method for efficiently paging a mobile phone according to claim 1, wherein said second calling channel broadcasts said second paging signal over a wider area than said first calling channel broadcast said first paging signal.
Claim 6
Dependent Claim
49 words
A method for efficiently paging a mobile phone according to claim 1, wherein said second calling channel employs more error correction coding than said first channel and said second channel broadcasts the second paging signal over a wider area than said first calling channel broadcasts said first paging signal.
Claim 7
Dependent Claim
72 words
A method for efficiently paging a mobile phone according to claim 1, wherein said second calling channel employs more error correction coding than said first calling channel in said first paging area, and said second calling channel broadcasts the second paging signal over a wider area than said first calling channel broadcasts said first paging signal, wherein said second paging signal does not include additional error correction coding in said wider area.
Claim 8
Dependent Claim
22 words
A method for efficiently paging a mobile phone according to claim 1, wherein said second calling channel transmits with a higher power.
Claim 9
Dependent Claim
37 words
A method for efficiently paging a mobile phone according to claim 1, wherein said second calling channel comprises a higher power transmission in the original paging area combined with a normal power transmission in a wider area.
Claim 10
Dependent Claim
42 words
A method for efficiently paging a mobile phone according to claim 1, wherein calls to mobiles using said first paging channel are queued in a first queue and calls to mobiles using said second paging channel are queued in a second queue.
Claim 11
Dependent Claim
58 words
A method for efficiently paging a mobile phone according to claim 1, further comprising the steps of: transferring said call to at least another calling channel when said mobile phone does not acknowledge said second paging signal within a second predetermined period of time; and transmitting at least another paging signal on at least said another calling channel.
Claim 12
Independent Claim
72 words
A method for calling particular mobile phones in a mobile telephone communication system comprising the steps of: determining a periodically recurring timeslot based on the mobile phone's identity for transmitting the call; transmitting the call repetitively in the recurring timeslot until a reply is received from the mobile phone or until a timeout period has expired; and transmitting the call using more redundant coding if the timeout period expires without a reply.
Claim 13
Independent Claim
72 words
A method for calling particular mobile phones in a mobile telephone communication system comprising the steps of: determining a periodically recurring timeslot based on the mobile phone's identity for transmitting the call; transmitting the call repetitively in the recurring timeslot until a reply is received from the mobile phone or until a timeout period has expired; and transmitting the call using more redundant coding if the timeout period expires without a reply.
Claim 14
Dependent Claim
78 words
A mobile phone capable of receiving calls in either a first channel or a second channel, comprising: means for transmitting a reply to a call received on the first channel using a first signal format; and means for transmitting a reply to a call received on the second channel using a second signal format, wherein the first signal format comprises a first amount of redundant coding and the second signal format comprises a second amount of redundant coding.
Claim 15
Dependent Claim
78 words
A mobile phone capable of receiving calls in either a first channel or a second channel, comprising: means for transmitting a reply to a call received on the first channel using a first signal format; and means for transmitting a reply to a call received on the second channel using a second signal format, wherein the first signal format comprises a first amount of redundant coding and the second signal format comprises a second amount of redundant coding.
Claim 16
Dependent Claim
31 words
A mobile phone according to claim 12, wherein the first signal format comprises transmission at a first power level and the second signal format comprises transmission at a second power level.
Claim 17
Dependent Claim
25 words
A mobile phone according to claim 12, wherein said first signal format comprises a short transmission and said second signal format comprises a long transmission.
Claim 18
Dependent Claim
35 words
A mobile phone according to claim 14, wherein the short transmission comprises a first number of timeslots of a TDMA frame and the long transmission comprises a second number of timeslots of the TDMA frame.
Claim 19
Dependent Claim
25 words
A mobile phone according to claim 12, wherein the first channel is a normal power channel and the second channel is a high power channel.
Claim 20
Dependent Claim
20 words
A mobile phone according to claim 12, wherein the first and second channels are different timeslots in a multiplex format.
Claim 21
Independent Claim
109 words
A method for efficiently paging a mobile radio in a radio telephone system having a plurality of mobile phones, comprising the steps of: transmitting a first paging signal for a first mobile phone on a first calling channel; transferring the call to at least a second calling channel when said first mobile phone does not acknowledge said first paging signal within a predetermined period of time; and transmitting a second paging signal for said first mobile phone on at least said second calling channel, wherein the second calling channel comprises a higher power transmission in the original paging area combined with a normal power transmission in a wider area.
Claim 22
Independent Claim
109 words
A method for efficiently paging a mobile radio in a radio telephone system having a plurality of mobile phones, comprising the steps of: transmitting a first paging signal for a first mobile phone on a first calling channel; transferring the call to at least a second calling channel when said first mobile phone does not acknowledge said first paging signal within a predetermined period of time; and transmitting a second paging signal for said first mobile phone on at least said second calling channel, wherein the second calling channel comprises a higher power transmission in the original paging area combined with a normal power transmission in a wider area.
