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.
Claims18
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.
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.
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.
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.
