fig1 shows one embodiment 10 of a system in which patron 102 with a wireless device , such as cellular telephone 12 , approaches podium 11 of a restaurant where host / hostess 101 is positioned . not shown are the plurality of other patrons mingling around awaiting a table to become available . in the embodiment shown , host / hostess 101 enters an identification number ( such as the calling number ) of wireless device 12 into controller 15 in any one of a number of ways . the identification number could be spoken or it could be radio frequency identification ( rfid ), near - field ( nf ) transferred via wireless device 12 via receiving device 14 . controller 15 is essentially the same as controller 25 as will be discussed in more detail hereinafter with respect to fig2 b . in one embodiment , control number is provided to host / hostess 101 by controller 15 or alternatively host / hostess 101 provides the control number for use by controller 15 . this control number is then stored in a memory in association with the calling identification number of the patron &# 39 ; s wireless device . when the table for patron 102 becomes available , host / hostess 101 inputs the control number of patron 102 into controller 15 which then establishes a communication link via either the public switch network , a wireless communication network , or a pager network ( not shown ) to wireless device 12 which then provides a signal or a message to patron 102 indicating the availability of a table . this message , if desired , could also provide other information pertaining to the table , such as its location , etc . while the patron is waiting for a table , messages can be sent to device 12 from the business establishment . these messages can be , for example , specials of the day , menus , coupons for special pricing , music or other entertainment . one or more of these messages could be a bidirectional communication . for example , a message could say , “ we are featuring a certain drink or hors d &# 39 ; oeuvre today . the price is $ 4 . 95 . do you wish to order ?” patron 102 then could choose to answer “ yes ,” “ no ” or ignore the message . any reply message would be communicated over a bidirectional link back through the network to controller 15 which would then take the necessary action to insure that the request of patron 102 is performed . while the system is shown in conjunction with a restaurant setting , any merchandise ( or service ) that a patron is waiting for can be the subject of the system . fig2 a shows , for example , an embodiment 20 , in which pharmacy 21 has drive - up window 201 . patron 202 is in his / her vehicle waiting for service . patron 202 has wireless device 22 which can communicate via rfid or nf communication via input device 24 to register an identification number , such as the calling number of wireless device 22 . alternatively , the calling number can be registered verbally with a person located at pharmacy 21 , or the calling number could be registered from a remotely located patron by having that patron call in and verbally present the calling number . if desired , a caller id or other device could provide the identification of the wireless device of the remote patron . in on embodiment , the calling identification could be from memory 204 of controller 25 ( fig2 b ) or from a remote system , such as remote system 220 which can be , for example , the system shown in the above identified copending application entitled , “ system and method for coordinating payment identification systems .” in operation , using system 20 a prescription ( rx ) or other merchandise desired from pharmacy 21 would be entered into controller 25 as well as into the normal pharmaceutical system ( not shown ) of establishment 21 . the rx can be called in by a physician and attached to the prescription would be the patron identification number . controller 25 operates in conjunction with the pharmacy system , to cross - link the patron identification , as obtained from the doctor , with the patron &# 39 ; s calling identification number and with a code number ( if desired ). an alternate method of delivering a rx to establishment 21 is , of course , by physically hand carrying the rx to an attendant , who would then register the patron &# 39 ; s calling identification in association with a code number . the patron then is free to leave the establishment or do other shopping in the establishment or elsewhere and from time to time messages can be delivered to the patron using , for example , the code number , with respect to other services available , such as specials , coupons , rebates , etc . at the time when the rx becomes available , the code number associated with the rx is communicated to controller 25 ( fig2 b ) which , in one embodiment , has computer 203 , memory 204 , message store 26 , voice - to - text device 27 and text - to - speech device 28 operating in association therewith . when the code number of the available rx arrives at controller 25 , controller 25 then retrieves from memory the patron &# 39 ; s calling number , such as the calling number of wireless device 23 for patron 203 . a proper message is then selected from message store 206 for communication via a communication link to patron device 23 . this communication link can be established locally from establishment 21 or it can be established from remote system 220 . in some instances during the filling process of the rx the pharmacist may require additional information about the patient or a clarification of the patient &# 39 ; s birth date or other information . if the information is available , for example , in memory 204 then upon initiation of a request for the information the information can be provided from memory . in some situations , the request for additional information will be sent from controller 25 to the patron ; such as patron 203 via wireless device 23 on a bidirectional link under control of the assigned control code . the patron could be asked for a birth date , an address , or other information . the patron then can communicate the information , either using a touch pad or verbally back to the pharmacist . the verbal communications could be , if desired , translated by voice - to - text device 27 . when patron 203 &# 39 ; s rx is ready , a communication is sent from message store 26 through the system to wireless device 23 so that patron 203 can drive up to window 201 to retrieve his / her filled rx . as the patron is approaching window 201 , wireless device 203 could identify itself , for example , via rfid or nf detector 24 , and the proper rx would be ready when patron 203 arrives at window 201 . if desired , when patron 203 is notified that the rx ( or other merchandise ) is available a price could be included in the message and the patron given the opportunity to authorize payment for the merchandise at that time . this authorization could be under control of the system and method discussed in the above - identified u . s . patent application , “ system and method for coordinating payment identification systems .” again , it should be pointed out that while the inventive concepts have been discussed with respect to a pharmacy , any type of establishment can utilize the concepts discussed herein so that a patron can register ( or have registered ) his / her calling identification and when the merchandise is ready the patron will be notified . while the patron is waiting for such notification , other messages can be delivered to the patron pertaining to services available , either at the establishment or in conjunction with the desires of the patron . fig3 shows one embodiment of flow chart 30 illustrating the processes of the inventive concepts . process 301 determines whether a patron has signed in with a service provider . the service provider can be a restaurant , a pharmacy , or any other type of commercial environment where notification of an event is important . process 302 determines whether the system already has a calling phone or pager number of the wireless device used by the patron . if the system does not already have that information , then process 303 controls the input of that calling information number . this could be by rfid or nf communication , caller id , verbal with a voice - to - text conversion , ( such as speech - to - text converter 27 , fig2 b ). process 304 assigns a local control number ( lcn ) to the phone number . note that process 304 is not necessary and the system could , if desired , use the actual phone number or caller identification number of the wireless device . for ease of discussion herein it will be assumed that an lcn is utilized . the lcn is stored in association with the phone number via process 305 . this storage could be , for example , in memory 204 , fig2 b , of controller 25 under control of pc 203 , but any other system , either local to the physical location of the patron or the place of establishment or in a remote system , such as system 220 , fig2 a could be used . fig4 shows an embodiment 40 of a process for receiving messages and notifications and communicating those messages to a patron from time to time . process 401 is the message control which determines which messages are to be sent at a given time . these messages can be prerecorded and selected by identification number or they could be input into the system live by a host / hostess , pharmacist , or other establishment member and converted if desired to speech via text - to - speech device 28 , fig2 b . process 402 determines if it is time to send a message to a patron . this determination can be , for example , based on the fact that an rx is filled or that other merchandise or service is available . the time of the message can be controlled such that , for example , if an rx is filled in the middle of the night , the notification will not go out until morning . process 403 , in conjunction with process 404 , generates the message and / or retrieves it from a data store and sets up a link to the wireless device via process 405 under control of controller 25 , fig2 b . the message is then sent via process 406 via either the public switched network , internet connection , packed switched network or otherwise , in accordance with the calling identification number provided during the initial registration period ( process 30 , fig3 ). process 407 determines if a reply is expected , i . e ., bidirectional communication has been set up . if not , then the original message link is terminated via process 408 . however , if a reply is expected , then process 409 , in conjunction with process 410 , determines if a reply has been generated and if so then the reply is sent ( process 411 ) and the link is ended ( process 412 ). note that process 410 can be established such that if a reply is not generated within a certain time a repeat message is sent to the patron to try to establish a bidirectional communication so as to obtain a reply message under control of process 415 . although the present invention and its advantages have been described in detail , it should be understood that various changes , substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims . moreover , the scope of the present application is not intended to be limited to the particular embodiments of the process , machine , manufacture , composition of matter , means , methods and steps described in the specification . as one of ordinary skill in the art will readily appreciate from the disclosure of the present invention , processes , machines , manufacture , compositions of matter , means , methods , or steps , presently existing or later to be developed that perform substantially the same function or achieve substantially the same result as the corresponding embodiments described herein may be utilized according to the present invention . accordingly , the appended claims are intended to include within their scope such processes , machines , manufacture , compositions of matter , means , methods , or steps .
