Selective wireless paging receiver and radio frequency searching method therefor

A wireless selective paging receiver comprising:

• means for receiving a plurality of frequencies of a plurality of wireless paging systems;
• means for storing the received frequencies of the plurality of wireless paging systems;
• means for sequentially switching each of the stored received frequencies to be synchronized;
• means for storing a plurality of pre-determined system information items;
• means for determining each receiving area to be receivable if there is a match between system information included in the received frequency and one of the plurality of pre-determined system information items stored in said paging receiver;
• means for storing a correlation of the frequencies which are currently received, the system information of receiving areas which are covered with the corresponding received frequencies, and the receiving area information thereof;
• means for indicating the receivable areas to a user of said receiver;
• and
• means for switching the frequency to a frequency corresponding to a receiving area selected from the indicated receiving areas.

• means for storing the received frequencies of the plurality of wireless paging systems;
• means for sequentially switching each of the stored received frequencies to be synchronized;
• means for determining a receiving area to be a receivable area if there is a match between system information included in the received frequency and one of the plurality of pre-determined system information items stored in said paging receiver;
• means for storing a correlation of the frequencies which are currently received, the system information of receiving areas which are covered with the corresponding received frequencies, and the receiving area information thereof;
• means for detecting a strength of an electric field of one of the received frequencies;
• means for indicating to a user of said receiver a name or channel number with the receiving reliability of corresponding receiving areas sorted in decreasing order of the receiving reliability;
• and
• means for allowing a user of said receiver to switch the frequency to a frequency corresponding to a receiving area selected from the receiving areas to be receivable.

A radio frequency searching method used with a wireless selective paging receiver comprising the steps of:

• storing a plurality of received frequencies of a plurality of wireless paging systems;
• sequentially switching the stored received frequencies so as to conduct a search operation;
• determining a receiving area to be receivable if there is a match between system information included in the received frequency and a plurality of system information items stored in said paging receiver;
• indicating to a user a name or channel number and receiving reliability of each receiving area in decreasing order of the receiving reliability;
• wherein
• the user selects a frequency channel from the thus-indicated receiving areas, and a radio frequency to be received is thereby determined.
