THAT WHICH IS CLAIMED:
1. A method of storing directory
information in a cellular radiotelephone, said method comprising the steps of:
providing a network directory database in a cellular telephone system, said network directory database comprising a plurality of telephone numbers;
prompting for user input of search criteria;
accepting user input of said search criteria;
generating a search request data signal within said cellular radiotelephone in response to said search criteria, said search request data signal including said search criteria;
sending said search request data signal from said cellular radiotelephone to said cellular radiotelephone system;
searching said network directory
database for a match with said search criteria to identify a subset of said plurality of telephone numbers ;
returning said subset of said plurality of telephone numbers to said cellular radiotelephone; and
storing said subset of said plurality of telephone numbers in said cellular radiotelephone.

2. A method according to Claim 1 wherein said step of sending said search request data signal comprises sending said signal over a digital control channel.

3. A method according to Claim 1 wherein;
said prompting step comprises prompting for user input of a plurality of items of search criteria;

said accepting step comprises accepting user input of each of said plurality of items of search criteria;
said generating step comprises
generating a separate search request data signal in response to each of said plurality of items of search criteria; and
said sending step comprises sending each of said search request data signals separately.

4. A method according to Claim 1 wherein said network directory database further comprises a plurality of search terms, each of said search terms being associated with a respective telephone number, and wherein said step of searching said network
directory database comprises the steps of:
comparing at least a portion of said search request data signal with said search terms;
choosing a subset of said plurality of search terms which match said portion of said search request data signal; and
identifying a subset of said plurality of telephone numbers associated with said chosen subset of said plurality of search terms.

5. A method according to Claim 4 wherein one of said search terms is chosen from the group comprising a first name, a last name, a middle name, an initial, and an address for a respective one of said telephone numbers.

6. A method according to Claim 4 wherein said returning step includes returning said subset of search terms to said cellular radiotelephone.

7. A method according to Claim 1 further comprising the steps of :
selecting an individual telephone number from said subset of telephone numbers; and
storing said individual telephone number in a personal directory in said cellular
radiotelephone .

8. A method according to Claim 7 further comprising the step of establishing a cellular
radiotelephone communication using said individual telephone number.

9. A method according to Claim 7 further comprising the step of displaying said subset of telephone numbers at said cellular radiotelephone.

10. A method according to Claim 1 wherein said step of generating said search request data signal further comprises converting said search request data signal to modem signals.

11. A cellular radiotelephone comprising:
memory means;
prompting means for prompting a user of said cellular radiotelephone to enter input search criteria;
accepting means for accepting said input search criteria;
generating means for generating a search request data signal within said cellular radiotelephone in response to said input search criteria, said search request data signal including said search criteria;
transmission means for transmitting said search request data signal from said cellular
radiotelephone to a cellular radiotelephone system wherein at least a portion of said search request data signal is compared with a network directory database to identify at least one telephone number;
reception means for receiving a return data signal from said cellular radiotelephone system, said return data signal including said telephone number ; and
storage means for storing said telephone number in said memory means .

12. A cellular radiotelephone according to Claim 11 wherein said transmission means comprises means for transmitting said search request data signal over a digital control channel.

13. A cellular radiotelephone according to Claim 11 further comprising calling means for
establishing a cellular radiotelephone communication using said telephone number in said memory means.

14. A cellular radiotelephone according to Claim 11 wherein said network directory database information includes a plurality of telephone numbers and a plurality of search terms, each of said search terms being associated with a respective telephone number, and wherein said search request data signal is compared with said search terms to locate a subset of said plurality of telephone numbers, and wherein said return data transmission comprises said subset of telephone numbers, and wherein said subset of telephone numbers is stored in said memory means.

15. A cellular radiotelephone according to Claim 14 wherein said return data transmission further comprises a subset of said plurality of search terms, each of said search terms of said subset being
associated with a respective telephone number in said subset of telephone numbers, and wherein said subset of search terms are stored in said memory means .

16. A cellular radiotelephone according to Claim 14 further comprising means for displaying said plurality of telephone numbers in said memory means.

17. A cellular radiotelephone according to Claim 16 further comprising designation means for designating one of said telephone numbers in said subset and for storing said designated telephone number in a personal directory in said cellular
radiotelephone .

18. A cellular radiotelephone according to Claim 17 further comprising calling means for
establishing a cellular radiotelephone communication using said designated telephone number.

19. A cellular radiotelephone according to Claim 11 further comprising a modem to convert said search request data signals to modem signals.

20. A cellular radiotelephone system
comprising:
a network directory database comprising a plurality of telephone numbers;
reception means for receiving a search request data signal from a cellular radiotelephone, said search request data signal including search criteria generated by said cellular radiotelephone in response to prompts for user input followed by user input of said search criteria;
search means for searching said network directory database for a match with said search
criteria to identify a subset of said plurality of said of telephone numbers; and transmission means for transmitting a return data signal including said subset of telephone numbers to said cellular radiotelephone.

21. A cellular radiotelephone system
according to Claim 20 wherein said search request data signal is received from said cellular radiotelephone over a digital control channel.
