Description: CALENDAR-DISPLAY APPARATUS, AND ASSOCIATED METHOD, T OR A MOBILE TERMINAL The present invention relates generally to a manner by which to display database information at a mobile terminal operable in a tadio communication system, such as a cellular mobile terminal opei able in a cellular communication system More particulai ly, the present invention lelates to apparatus, and an associated method, by which to display calendar information at a mobile terminal Calendar items stored, 01 generated, locally and calendar items stored, or generated, at a I emote source, such as a network calendar database, are displayable simultaneously at the mobile terminal BACKGROUND OF TH E INVENTION Advancements in communication technologies hav e permitted the development, installation, and widespread usage ol wn eless communication systems through which to communicate telephonically In a wireless communication system, a l adio link loi ms at least a poi tion ot a communication path upon which communication signals ai e ti ansmitted Increased mobility oi communication is. as a l esult, pci mittcd thi ough the utilization ot a wireless communication s\ stem The netwoi k intrasti ucture ot \ ui ious tvpcs ol cellulai communication systems, toi instance, have been installed thi oughout signi cant geogi aphical areas Large numbers ot subscribers to such cellulai communication systems ai e able to communicate telephonically w hen positioned in areas encompassed by the network infrastructuie ot the system pui suant to which subscription is made Telephonic communication ot both voice and data is generally permitted in such cellulai communication systems A. subscriber to a cellulai communication system K picallv utilizes a mobile terminal which is lormed oi a radio ti anscen ei capable ol both ti ansmitting and receiving l adio signals communicated upon l adio links with the network infrastructure of the communication system The tei m user shall be used herein to identify one utilizing the mobile terminal. Some communication systems utilize digital communication techniques in which information is digitized prior to its communication and subsequent to its reception. Processing circuitry is utilized to act upon information, prior to its transmission, and subsequent to its reception. The circuitry forming a mobile terminal is oftentimes packaged in a housing which permits convenient carriage of the mobile terminal by a user. Various constructions of mobile terminals are of physical dimensions permitting a user thereof to carry the mobile terminal in a shirt pocket, or the like, of the user. Because the mobile terminal utilizes processing circuitry, the processing circuitry can also be utilized to perform functions in addition to functions required to effectuate conventional communication operations. That is to say, functionality of other devices can be incorporated into the mobile terminal. For instance, information processing and retrieval functions are sometimes incorporated into a mobile terminal. For instance, some mobile terminals are capable of communicating with a device connected to a packet data network, such as the Internet. That is to say, packets of data are able to be communicated between a mobile terminal and the device upon a communication pack which includes both the radio link and also a wireline path extending through a packet data backbone to the device. The mobile terminal is able, thereby, to be operated in a manner analogous to that of a personal computer, or other processing device, more typically utilized to access web-based devices. Online calendars are exemplary of information retrievable from a device coupled to the Internet, or other packet data, backbone. Online calendars generally provide one or more of three types of views. One exemplary online calendar provides a personal calendar view listing the personal calendar of a user. Another online calendar provides an event list of a plurality of events, such as events occurring at a particular facility or events occurring on a particular date. And, another online calendar view forms an interests calendar which contains a subset of an event list filtered by an interest criteria. Analogous personal calendars are also available for local use at a processing device, such as a personal computer. Such local calendars would also be available for personal use at a mobile terminal containing appropriate circuitry to access , display, and update a local calendar. A mobile terminal operable in a G SM (Global System for Mobile communication) communication system which provides for SMS (Short Message Service) messaging is able to receive and send calendar items by way of a SMS message. Also, calendar items are selectable and a browser application is operable to open automatically a calendar application to handle the calendar item, such as vCalendar or /Calendar. The selection of the calendar application can be based, for instance, on the file type assoc iated therewith, such a .VCS. Online calendars are advantageous for the reason that a user is able to access the calendar using any processing device connectable to the Internet, or other packet-based, backbone. However, the ability to access the backbone, and in turn, the device at which the online calendar is located is, of course, required. Conversely, locally-based calendars are accessible irrespective of access to the backbone. But, calendar items are limited to items which are locally stored or generated. Conventionally, there is little interaction between conventional online calendars and locally-based calendars. The advantages inherent of an online calendar, therefore, are limited to users of online calendars. And, the advantages inherent of a locally-based calendar arc available only to users of locally-based calendars. If a manner could be provided by which to provide for interaction between locally-based calendars and online calendars, an improved calendar application would be provided. It is in light of this background information related to the display of database information that the significant improvements of the present invention have evolved. SUMMARY OF THE INVENTION The present invention, accordingly, advantageously provides apparatus, and an associated method, by which to display calendar information at a mobile terminal operable in a radio communication system. The calendar information displayable at the mobile terminal permits both calendar items stored, or generated, locally at the mobile terminal and calendar items stored, or generated, at a remote source, such as a network calendar database, to be displayed simultaneously at the mobile terminal. Through operation of an embodiment of the present invention, calendar displays generated pursuant to execution of a calendar application include calendar items provided by both a network calendar data base by way of a radio link and also with calendar items stored locally at the mobile terminal. The advantages inherent of both a locally-based calendar application and also of a network-based calendar application are prov ided by the calendar application of an embodiment of the present invention. Up to date information pertaining to events o f interest to a user of the mobile terminal are retrievable through operation of the calendar application and displayable at a portable, mobile terminal. Events and information, personal to the user of the mobile terminal, or otherwise not desired to be stored at a network-based device, conversely, are storable locally at the mobile terminal, thereby providing confidentiality of the personal information. Calendar displays displayable by the mobile terminal through operation of the calendar application of an embodiment of the present invention thereby permits upon a single calendar display calendar items, stored locally to maintain the confidentiality of such items, together with calendar items retrieved from a remote, network calendar database. In one aspect of the present invention, calendar displays are displayed in the form of sheets upon a visual display ice, such as a Liquid Crystal Display (LCD) screen. One sheet-type is a local sheet in which calendar items retrieved from a local storage element, or locally-entered, calendar items are positioned on the sheet and displayed at the display element of the mobile terminal. The local sheet is exportable to a remote server which forms the network calendar data base as well as another appropriate device through which the sheet is selected to be exported. Another sheet-type is a pushed sheet in which calendar items are downloaded from a remote location, such as a network calendar data base, to be stored at the storage element of the mobile terminal. Calendar items displayed upon the pushed sheet include the calendar items downloaded to the mobile terminal. Because the calendar items, once downloaded to the mobile terminal, are stored thereat, immediate retrieval of the calendar items is thereafter possible irrespective of subsequent connection, or reeonnection, of the mobile terminal to a remote network device. And, another sheet-type is a network sheet in which calendar items are stored at a network calendar database and are retrieved therefrom to be displayed upon the network sheet. Retrieval of the calendar items to form the network sheet require a connection between the mobile terminal and the network database. Because the calendar items are stored at the network data base, such items are updatable, as appropriate. Thereby, the calendar items which form a network sheet are maintainable in an up-to-date level of accuracy. The calendar items forming the network sheet are also storable at the mobile terminal in like manner to the manner by which the calendar items of the pushed sheets are storable at the mobile terminal. In one implementation, a calendar application is provided for a mobile terminal operable in a GSM (Global System for Mobile communications) cellular communication system. In one implementation, the GSM system provides for SMS (Short Message Service) messaging, and in another implementation, the GSM system further provides for GPRS (General Packet Radio Service). The mobile terminal is operable in an implementation in which the GSM system provides for SMS messaging to send and to receive SMS messages. And, in an implementation in which the GSM system further provides for GPRS, the mobile terminal is further operable to send and to receive packet data pursuant to GPRS . A calendar application is executable, such as through a user request to display selected calendar items upon a display element of the mobile terminal. Both calendar items stored, or entered locally at the mobile terminal, are displayable upon the display element of the mobile terminal, and calendar items retrieved from a remote network calendar database are displayable upon the display element of the mobile terminal. Calendar items retrieved from the network database and provided locally are displayable together upon a common display sheet, thereby to provide a user of the mobile terminal with both such calendar items. In these and other aspects, therefore, calendar-display apparatus, and an associated method, is provided for a mobile terminal for displaying calendar information. The mobile terminal is operable in a radio communication system having network infrastructure with which the mobile terminal communicates by way of a radio link. The network infrastructure is coupled to a network-based calendar information source containing at least one network-based calendar item. A mobile-based calendar information source is positioned at the mobile terminal. The mobile-based calendar information source contains at least one mobile-based calendar item. A retriever is positioned at the mobile terminal. The retriever retrieves at least a selected network-based calendar item stored at the network-based calendar information source. The retriever further retrieves at least a selected mobile- based calendar item stored at the mobile-based calendar information source. A display element is coupled to receive indications of the selected network- based calendar item and of the selected mobile-based calendar item. The display element displays together, in human perceptible form, the selected network-based calendar item and the selected mobile-based calendar item. A more complete appreciation of the present invention and the scope thereof can be obtained from the accompanying drawings, which are briefly summarized below, the following detailed description o f the presently- preferred embodiment of the invention, and the appended claims.

DETAILED DESCRIPTION O F THE PREFERRED EM BODIM ENT Figure 1 illustrates a communication system, shown generally at 10, in which an embodiment of the present invention is operable. While the description shall be described with respect to the exemplary system shown in Figure 1 , it should be understood that such description is by way of example only. An embodiment of the present invention is analogously operable in other types of communication systems. For instance, while the exemplary system shown in Figure 1 includes a GS M network, operation of an embodiment of the present invention can similarly be described with respect, e.g., to a so-called third generation network, such as that utilizing ( W) CDMA (wideband code division multiple access). Accordingly, operation of an embodiment of the present invention can analogously be described with respect to such other types of communication systems. The communication system 1 provides for wireless communications with a mobile station 12 by way of a radio link, here including downlink and uplink channels 14 and 16, respectively. In the exemplary implementation, the communication system 10 forms a GSM (Global System for Mobile communications) cellular communication system which provides for GPRS (General Packet Radio Service) as well as SMS (Short Message Service) messaging The mobile station 12 forms a GSM mobile station operable pursuant to the appiopπate GSM standaid to communicate by way ot the downlink 14 and uplmk 16 in conventional mannei with a l emote communication system In conventional mannei, the mobile station includes lecener ciicuitiy 24 and transmittei ciicuitry 26 capable ot leceiving and tiansmitting, respectively, communication signals by way ol an antenna tiansducer 28 The mobile station 12 is operable to effectuate cncuit-switched communications by way of the downlink and uplink 14 and 16 The mobile station is furthei operable to communicate SMS messaging puisuant to the protocol set foith in the appropriate GSM standaid and also to ellccluate GPRS opeiations, also puisuant to the appropriate GSM standaid SMS messages and GPRS opeiations aie peifoimed upon shaied uplink and downlink channels upon which packets of data aie communicated with the mobile station The mobile station tuithci includes a usα inteilace 32, heie including a keypad input actuator 34, selectably actuable by a usei ol the mobile station The usei mteiface also includes a display device, heie a LCD (Liquid Ciystal Display) element 36 I he input actuatoi ^4 and the I ( D element 36 aie coupled to a controllei 38 I he contiollei " 58 is opeiable, imei aha, to contiol operations ol the leceive ciicuitiv 24 and tiansmit ciicuitiy 26, such as lcsponsive to usei actuation ot the keypad input actuatoi 34 The contioller is also opeiable to ellectuate the geneiation ol displays, puisuant to opeiation of an embodiment oi the piescnt invention, upon the LC D element 36 The mobile station iuithei includes a stoiage element 42 opeiable to stoie calendai items and sheet templates theieat I he memoiv, 42 is a lead/write memoiy to peimit calendai items leliieved liom elsevheie, oi geneiated thiough actuation ot selected actuation keys ol the keypad actuatoi 34 to be stoied thereat and to be updated, as appiopπate The contiollei includes a functional element heie identified as a letnevei 44 The letnevei is opeiable dining opeiation of an embodiment ol the piesent invention, to ictiieve calendai items stoied at the stoiaue element 42 for display upon the LCD element 36. The retriever 44 is also operable to effectuate the retrieval of remotely-stored calendar items, also for display at the LCD element 36, together with the locally-stored calendar elements, to be displayed theretogether upon a common display at the LCD element. The communication system further includes the network infrastructure of the PLMN (public land mobile network), here a GSM network 46. The network 46 is here shown to include a base station system 48 and an SGSN (Serving GPRS Support Node) 54. The elements of the network infrastructure of the GSM network are operable in conventional manner and provide transceiving switching, and routing function, all as set forth in greater detail in the appropriate GSM specification. The SGSN 54, in turn, is coupled, in conventional manner to a GGSN (Gateway GPRS Support Node) 56. And. in turn, the GGSN 56 is coupled to a packet data network, here the Internet backbone 62. A server 64 containing a network calendar database 66 is coupled, in conventional manner, to the Internet backbone. Access to the contents of the network calendar database is effectuated pursuant to retrieval operations by, e.g., TCP/I P (Transport Control Protocol) requests. A SMS (Short Message Service) center 68 is further shown in the figure. I n conventiona l manner, the SM S center is coupled to the GSM network 46 and to the Internet backbone 62, here by way of a gateway 70. The SMS center functions as a store and forward center for storing and forwarding SMS messages generated during operation of the communication system. During operation of an embodiment of the present invention, the retriever 44 of the controller 38 of the mobile station is operable to cause retrieval of calendar items stored at the network calendar database 66 so that the retrieved calendar items can be displayed al the LCD element 36. Because the retriever is operable both to retrieve locally-stored calendar items from the storage element 42 and to effectuate retrieval of calendar items stored at the network calendar database 66, the display displayed upon the LCD element is able to include both network-stored calendar items and locally-stored calendar items upon a common calendar display. In the exemplary implementation, initiation of operation of a calendar display is effectuated by user actuation of selected keys of the keypad actuator 34. The retriever 34 is operable to detect the actuation of the keypad actuator indicative of the request for the display of the calendar program. Responsive thereto, the retriever retrieves one or more calendar items stored at the storage element 42. The retriever is further operable to cause the transmit circuitry 26 to generate a message which is transmitted upon a channel of the uplink 16, thereafter to be detected by the base station 48 and routed through the elements of the network portion of the communication system 10 to the server 64. The one or more network-based calendar items contained in the request are routed back to the mobile terminal in reverse manner transmitted upon a channel of the dow nlink 1 4, detected by the receive circuitry 24 of the mobile station and thereafter caused by the retriever 44 to be displayed at the LCD element 36. In one implementation, the retriever causes the transmit circuitry 26 to generate a SMS message which is transmitted upon a channel of the uplink 1 6, detected by the base station system 48 and routed to the SMS center 68. The SMS center 68, in turn, causes generation of a request which is routed to the server 64. A reply containing the one or more network-calendar elements is returned to the SMS center 68. And, the SMS center 68 generates a SMS message which is routed through the elements of the network infrastructure of the GSM network and transmitted upon a channel of the downlink 14 to the mobile station 12. In an implementation in which the GSM system provides for GPRS, a GPRS message is caused to be generated by the transmit circuitry 26. The GPRS message is routed through the netw ork inlϊastructui e of the GSM network, thereafter to be routed to the server 64. One or more network-based calendar items are retrieved and returned by way of a corresponding GPRS message which, when received at the mobile station, is caused to be displayed upon the LCD element 36 as a calendar display on a common user interface with calendar items retrieved from the storage element 42. In one implementation, calendar displays displayed upon the LCD element are displayed in the form of sheets. One sheet-type is a local sheet including calendar items l etrieved from the storage element 42 or entered through actuation of the keypad actuator 34. Such local sheets are exportable to the network calendar database 66 through the transmission of messages, such as SMS messages or GPRS messages containing the calendar information forming the local sheet. Another sheet-type is a pushed sheet which contains calendar items retrieved, in manners as above-described from the network calendar database 66 and then stored at the storage element 42. Once stored at the storage element, the calendar items are retrievable thereafter irrespective of subsequent connection of the mobile terminal by way of a radio link with the server 64. And, another sheet-type is a network sheet. Calendar items displayable upon a network sheet are retrieved from the network calendar database 66, in manners above-described, and updating of the calendar items are made by appropriate transmission of messages used to write over, or otherwise update, existing calendar items stored at the network calendar database. Figure 2 illustrates an exemplary calendar display, shown generally at 76, generated during operation of an exemplary embodiment of the present invention. The calendar display 76 is displayed upon the LCD element 36 of the mobile station 12. The display 76 here forms a daily calendar listing scheduled events indexed against a time-of-day index identified by a listing of successive hours of the day in a left-most (as shown) column 78. The calendar display 76 includes a first screen body portion 82 and a second screen body portion 84. The first screen body portion 82 initially lists personal calendar items, i.e., calendar items retrieved from the storage element 42 (shown in Figure 1 ). The calendar item "meeting with Carl" scheduled at 10:00 is a local calendar item. The calendar items displayed at the second screen body portion 84 are, initially, network-stored calendar items, i.e., calendar items retrieved from the network calendar database 66 (shown in Figure 1 ). The calendar items "Tampere basketball starts," "Tampere basketball finals," and "Ilves-Tampere, Hakametsa" are such network-based calendar items. Additional operation of an embodiment of the piesent invention permits the netwoik-based calendai items displayed upon the calendai display to be copied to the stored at the local stoiage element ot the mobile station As shown at the calendai entiy at 1 00 houis the netv oi -based calendar item displayed at the second scieen body poition is copied to the fust scieen body portion A top (as shown) toolbai portion of the calendai display The toolbai poition includes an identification poition 86, heie indicating that the calendar display is "My Calendai " a push infoimation indicatoi 88 indicating the type of calendar items which aie downloaded to the mobile station without specific lequest theiefoi, a second pushed poition 92 heie indicating that ' ( ompany ' calendai items are to be pushed to the mobile station a thud push-poition 94, heie indicating that "Spoil 1 lnlυimation is pushed to the mobile station, and a fouith push-portion 96, heie indicating also that "MT V3" iniormation is to be pushed to the mobile station, and an indicatoi 98 idcntilymg a link list ol available calendar views displayable at the calendai display dev ice The calendar display 76 thereby pro ides a convenient display to a us i ot the mobile station of both locally-stoicd calendai items and nctv oi -sloied calendai items Other calendai displays aie analogously also able to be displayed at the LCD element 36 (shown m I iguie 1 ) Figure 3 illustrates a message sequence diagram, shown geneially at 102, showing the sequence of signals geneiatcd dunng opeiation of the communication system shown Tigiπe 1 puisuant to an embodiment of the piesent invention First, and as indicated bv th segment 104 a signal is geneiated lesponsive to usei actuation ol a kc ad actuatoi of the usei interface 32 The signal indicates initiation ol a icquest loi display at the display element of the mobile station of a calendai display I he contiollei 34 detects the signal The contiollei, in tuin causes the tiansmit ciicuitiy ot the mobile station to geneiate a signal heie a SMS message lcpiesented by the segment 106 hich is sent to the base station sv tcm 48 ot the netwoik mliastiuctuie of the communication svstem I he base station utes a signal repiesentative ot the lequest, and heie indicated b> the segment 108, to the SMS center 68. And, the SMS center, in turn, generates a signal, here indicated by segment 1 12, which accesses the network database 66 of the server 64 (shown in Figure 1 ). Calendar items are retrieved from the network database, and signals representative thereof, here indicated by the segment 1 14, are routed back through the SMS center and to the base station system 48. The base station system generates a downlink signal, here represented by the segment 1 16, which is detected by the receive circuitry 24 (shown in Figure 1 ) of the mobile station, and provided to the controller 44. The controller, in turn, and as indicated by the segment 1 1 8, sends signals to the LCD element of the user interface. A calendar display containing the retrieved calendar item is displayed thereat. Figure 4 illustrates a method flow diagram, shown generally at 1 32, of an embodiment of the present invention. The method 1 32 is operable to cause the display of calendar information at a mobile terminal operable in a radio communication system. First, and as indicated by the block 134, at least one network-based calendar item is stored at a network-based calendar information source. Then, and as indicated by the block 1 36, at least one mobile-based calendar item is stored at a mobile-based calendar information source located at the mobile terminal. Thereafter, at least a selected network-based calendar item stored at the network-based calendar information source and at least a selected mobile- based calendar item are retrieved. And, as indicated by the block 142, a selected network-based calendar and a selected mobile-based calendar item are together displayed at a display element of the mobile terminal. Thereby, through operation of an embodiment of the present invention, calendar items, stored at both a network calendar database and locally at a mobile terminal, are displayable together at the mobile terminal upon a common calendar display. The previous descriptions are of preferred examples for implementing the invention, and the scope of the invention should not necessarily be limited by this description.
