1. Field of the Technology
The present disclosure relates generally to communication devices and messaging, and more particularly to user interface techniques for use providing a presentation for the composition of messages having size limitations.
2. Description of the Related Art
Today, wireless communication devices which operate in wireless communication networks have many capabilities, which may include a wireless messaging capability. Wireless messaging may include text messaging, such as short message service (SMS) messaging, multimedia messaging service (MMS) messaging, electronic-mail (e-mail) messaging, instant messaging, as a few examples.
Some of these types of messaging capabilities, such as SMS messaging, may have limitations on the number of characters permitted in each message, and/or limitations on the number of characters permitted in each message segment utilized to construct a message, and/or limitations on the number of messages segments utilized to construct a message. In some environments, it may be preferable for the user of the wireless communication device to be informed of such limitations during composition of a message (e.g. for reasons of cost).
What are needed are advantageous methods and apparatus for use in a wireless communication device for processing such messages, including methods and apparatus for use in providing presentations for the composition of such messages.
Embodiments of present disclosure will now be described by way of example with reference to attached figures, wherein:
Methods and apparatus for use in providing presentations for the composition of messages having size limitations are described. In one illustrative technique, the communication device receives, via its user interface, one or more character inputs in a message composition field for a new message being composed. While a character count of the message is less than a warning count value, the device refrains from presenting the number of allowed characters remaining for entry in the message. On the other hand, while the character count is greater than or equal to the warning count value, the device causes the number of allowed characters remaining for entry in the message to be presented for display. In one example, the number of allowed characters remaining for entry is provided in an alert bar, which is presented by being set in motion from an initial hidden position behind the message composition field to a final revealed position, with intermediate positions therebetween.
To illustrate one exemplary environment within which the present techniques may be practiced,
In most modern communication devices, controller 106 is embodied as a central processing unit (CPU) which runs operating system software in a memory component (not shown). Controller 106 normally controls overall operation of wireless device 102, whereas signal processing operations associated with communication functions are typically performed in RF transceiver circuitry 108. Controller 106 interfaces with device display 112 to display received information, stored information, input requests, and the like. Keyboard 114, which may be a telephone type keypad or full alphanumeric keyboard, is normally provided for entering data for storage in wireless device 102, information for transmission to network 104, a telephone number to place a telephone call, commands to be executed on wireless device 102, and possibly other or different input requests. In one embodiment, keyboard 114 may be or include a physical keyboard or a virtual or “soft” keyboard, implemented, for example, by way of images of keys rendered on a touch screen display.
Wireless device 102 sends communication signals to and receives communication signals from network 104 over a wireless link via antenna 110. RF transceiver circuitry 108 performs functions similar to those of base station 138, including for example modulation/demodulation and possibly encoding/decoding and encryption/decryption. It is also contemplated that RF transceiver circuitry 108 may perform certain functions in addition to those performed by base station 138. It will be apparent to those skilled in art that RF transceiver circuitry 108 will be adapted to particular wireless network or networks in which wireless device 102 is intended to operate.
Wireless device 102 includes a battery interface 118 for receiving one or more rechargeable batteries 120. Battery 120 provides electrical power to (most if not all) electrical circuitry in wireless device 102, and battery interface 118 provides for a mechanical and electrical connection for battery 120. Battery interface 118 is coupled to a regulator 122 which regulates power for the device. When wireless device 102 is fully operational, an RF transmitter of RF transceiver circuitry 108 is typically keyed or turned on only when it is sending to network 104, and is otherwise turned off to conserve resources. Such intermittent operation of transmitter has a dramatic effect on power consumption of wireless device 102. Similarly, an RF receiver of RF transceiver circuitry 108 is typically periodically turned off to conserve power until it is needed to receive signals or information (if at all) during designated time periods.
Wireless device 102 may consist of a single unit, such as a data communication device, a cellular telephone, a multiple-function communication device with data and voice communication capabilities such as a mobile telephone with data communication functionality, a personal digital assistant (PDA) enabled for wireless communication, a tablet computing device, or a computer incorporating an internal modem. Alternatively, wireless device 102 may be a multiple-module unit comprising a plurality of separate components, including but in no way limited to a computer or other device connected to a wireless modem. In particular, for example, in the wireless device block diagram of
Wireless device 102 may operate using a Subscriber Identity Module (SIM) 126 which is connected to or inserted in wireless device 102 at a SIM interface 124. SIM 126 is one type of a conventional “smart card” used to identify an end user (or subscriber) of wireless device 102 and to personalize the device, among other things. Without SIM 126, the wireless device terminal is not fully operational for communication through wireless network 104. By inserting SIM 126 into wireless device 102, an end user can have access to any and all of his/her subscribed services. In order to identify the subscriber, SIM 126 contains some user parameters such as an International Mobile Subscriber Identity (IMSI) and a Mobile Station Integrated International Service Digital Network (MSISDN). In addition, SIM 126 is typically protected by a four-digit Personal Identification Number (PIN) which is stored therein and known only by the end user. An advantage of using SIM 126 is that end users are not necessarily bound by any single physical wireless device. Typically, the only element that personalizes a wireless device terminal is a SIM card. Therefore, the user can access subscribed services using any wireless device equipped to operate with the user's SIM.
Some information stored on SIM 126 (e.g., address book and SMS messages) may be retrieved and visually displayed on display 112, Wireless device 102 has one or more software applications which are executed by controller 106 to facilitate the information stored on SIM 126 to be displayed on display 112. Controller 106 and SIM interface 124 have data and control lines 144 coupled therebetween to facilitate the transfer of the information between controller 106 and SIM interface 124 so that the information may be visually displayed. An end user enters input requests at keyboard 114, for example, and in response, controller 106 controls SIM interface 124 and SIM 126 to retrieve the information for display. The end user may also enter input requests at keyboard 114, for example, and, in response, controller 106 controls SIM interface 124 and SIM 126 to store information on SIM 126 for later retrieval and viewing. The software applications executed by controller 106 may include an application to retrieve and display address book information stored on SIM 126, and an application to retrieve and display SMS message information stored on SIM 126.
Wireless device 102 communicates in and through wireless communication network 104. In the embodiment of
Base station 138, including its associated controller and antenna tower 136, provides wireless network coverage for a particular coverage area commonly referred to as a “cell”. Base station 138 transmits communication signals to and receives communication signals from wireless devices within its cell via antenna tower 136. Base station 138 normally performs such functions as modulation and possibly encoding and/or encryption of signals to be transmitted to the wireless device in accordance with particular, usually predetermined, communication protocols and parameters, under control of its controller. Base station 138 similarly demodulates and possibly decodes and decrypts, if necessary, any communication signals received from wireless device 102 within its cell. Communication protocols and parameters may vary between different networks. For example, one network may employ a different modulation scheme and operate at different frequencies than other networks.
The wireless link shown in communication system 100 of
For all wireless devices 102 registered with a network operator, permanent data (such as wireless device 102 user's profile) as well as temporary data (such as wireless device's 102 current location) are stored in HLR 132, In case of a voice call to wireless device 102, HLR 132 is queried to determine the current location of wireless device 102. VLR 130 is responsible for a group of location areas and stores the data of those wireless devices that are currently in its area of responsibility. This includes parts of the permanent wireless device data that have been transmitted from HLR 132 to VLR 130 for faster access. However, VLR 130 may also assign and store local data, such as temporary identifications. Optionally, VLR 130 can be enhanced for more efficient co-ordination of GPRS and non-GPRS services and functionality (e.g., paging for circuit-switched calls, and combined GPRS and non-GPRS location updates).
Being part of the GPRS network, a Serving GPRS Support Node (SGSN) is at the same hierarchical level as MSC 140 and keeps track of the individual locations of wireless devices. An SGSN also performs security functions and access control. Further, a Gateway GPRS Support Node (GGSN) provides interworking with external packet-switched networks and is connected with SGSNs via an IP-based GPRS backbone network. The SGSN performs authentication and cipher setting procedures based on the same algorithms, keys, and criteria as in existing GSM. For SMS transfer over GPRS, the SGSN is used in place of MSC 140.
In order to access GPRS services, wireless device 102 first makes its presence known to wireless network 104 by performing what is known as a GPRS “attach”. This operation establishes a logical link between wireless device 102 and the SGSN and makes wireless device 102 available to receive, for example, pages via SGSN, notifications of incoming GPRS data, or SMS messages over GPRS. In order to send and receive GPRS data, wireless device 102 assists in activating the packet data address that it wants to use. This operation makes wireless device 102 known to the GGSN; interworking with external data networks can thereafter commence. User data may be transferred transparently between wireless device 102 and the external data networks using, for example, encapsulation and tunneling. Data packets are equipped with GPRS-specific protocol information and transferred between wireless device 102 and the GGSN.
SMS makes use of SMS-SC 128 which acts as a store-and-forward system for relaying short messages. Messages are stored in the network until the destination device becomes available, so a user can receive or transmit an SMS message at any time, whether a voice call is in progress or not. SMS-SC 128 may be integrated with a Gateway MSC for Short Message Service (SMS-GMSC) and an Interworking MSC for Short Message Service (SMS-IWMSC), as would be the case shown in
As apparent from the above, the wireless network includes fixed network components including RF transceivers, amplifiers, base station controllers, network servers, and servers connected to network. Those skilled in art will appreciate that a wireless network may be connected to other systems, possibly including other networks, not explicitly shown in
If wireless device 202 is enabled for two-way communication, wireless device 202 will normally incorporate a communication subsystem 211, which includes a receiver 212, a transmitter 214, and associated components, such as one or more (e.g., embedded or internal) antenna elements 216 and 218, local oscillators (LOs) 213, and a processing module such as a digital signal processor (DSP) 220. Communication subsystem 211 is analogous to RF transceiver circuitry 108 and antenna 110 shown in
Network access requirements will also vary depending upon type of network utilized. In GPRS networks, for example, network access is associated with a subscriber or user of wireless device 202. A GPRS device therefore operates in conjunction with a Subscriber Identity Module, commonly referred to as a “SIM” card 256, in order to operate on the GPRS network. Without such a SIM card 256, a GPRS device will not be fully functional. Local or non-network communication functions (if any) may be operable, but wireless device 202 will be unable to carry out any functions involving communications over the network. SIM 256 includes those features described in relation to
ireless device 202 may send and receive communication signals over the network after required network registration or activation procedures have been completed. Signals received by antenna 216 through the network are input to receiver 212, which may perform such common receiver functions as signal amplification, frequency down conversion, filtering, channel selection, and like, and in the example shown in
Wireless device 202 includes a microprocessor 238 (which is one implementation of controller 106 of
Microprocessor 238, in addition to its operating system functions, enables execution of software applications on wireless device 202. A predetermined set of applications which control basic device operations, including at least data and voice communication applications (such as a user interface technique), will normally be installed on wireless device 202 during its manufacture. One exemplary application that may be loaded onto wireless device 202 may be a personal information manager (PIM) application having the ability to organize and manage data items relating to user such as, but not limited to, e-mail, calendar events, voice mails, appointments, and task items. Naturally, one or more memory stores are available on wireless device 202 and SIM 256 to facilitate storage of NM data items and other information.
The PIM application has the ability to send and receive data items via the wireless network. In an exemplary embodiment, PIM data items are seamlessly integrated, synchronized, and updated via the wireless network, with the wireless device user's corresponding data items stored and/or associated with a host computer system thereby creating a mirrored host computer on wireless device 202 with respect to such items. This is especially advantageous where the host computer system is the wireless device user's office computer system. Additional applications may also be loaded onto wireless device 202 through network, an auxiliary I/O subsystem 228, serial port 230, short-range communications subsystem 240, or any other suitable subsystem 242, and installed by a user in RAM 226 or a non-volatile store for execution by microprocessor 238. Such flexibility in application installation increases the functionality of wireless device 202 and may provide enhanced on-device functions, communication-related functions, or both. For example, secure communication applications may enable electronic commerce functions and other such financial transactions to be performed using wireless device 202.
In a data communication mode, data such as an SMS message will be processed by communication subsystem 211 and input to microprocessor 238. Microprocessor 238 may further process the signal for output to display 222 or alternatively to auxiliary I/O device 228, A user of wireless device 202 may also compose data items, such as SMS messages, using keyboard 232 in conjunction with display 222 and possibly auxiliary I/O device 228. Keyboard 232 may be a complete alphanumeric keyboard and/or telephone-type keypad. In one embodiment, keyboard 232 may be or include a physical keyboard or a virtual or “soft” keyboard, implemented, for example, by way of images of keys rendered on a touch screen display. The composed items may be transmitted over a communication network through communication subsystem 211.
For voice communications, the overall operation of wireless device 202 is substantially similar, except that the received signals are output to speaker 234 and signals for transmission are generated by microphone 236. Alternative voice or audio I/O subsystems, such as a voice message recording subsystem, may also be implemented on wireless device 202. Although voice or audio signal output may be accomplished primarily through speaker 234, display 222 may also be used to provide an indication of the identity of a calling party, duration of a voice call, or other voice call related information, as some examples.

Wireless device 202 also includes a battery interface (such as that described in relation to
As shown in
Network entry point 305 is generally used to multiplex and demultiplex amongst many gateways, corporate servers, and bulk connections such as the Internet, for example. There are normally very few of these network entry points 305, since they are also intended to centralize externally available wireless network services. Network entry points 305 often use some form of an address resolution component 335 that assists in address assignment and lookup between gateways and wireless devices. In this example, address resolution component 335 is shown as a dynamic host configuration protocol (DHCP) server as one method for providing an address resolution mechanism.
A central internal component of wireless data network 345 is a network router 315. Normally, network routers 315 are proprietary to the particular network, but they could alternatively be constructed from standard commercially available hardware. The purpose of network routers 315 is to centralize a plurality (e.g., thousands) of base stations 320 normally implemented in a relatively large network into a central location for a long-haul connection back to network entry point 305. In some networks there may be multiple tiers of network routers 315 and there may be cases where there are master and slave network routers 315, but in all such cases the functions of network routers 315 are similar. Often network router 315 will access a name server 307, in this case shown as a dynamic name server (DNS) 307 as used in the Internet, to look up destinations for routing data messages. Base stations 320, as described above, provide wireless links to wireless devices such as wireless device 202.
Wireless network tunnels such as a wireless tunnel 325 are opened across wireless network 345 in order to allocate necessary memory, routing, and address resources to deliver IP packets. In GPRS, such tunnels 325 are established as part of what are referred to as “PDP contexts” (i.e., data sessions). To open wireless tunnel 325, wireless device 202 may use a specific technique associated with wireless network 345. The step of opening such a wireless tunnel 325 may require wireless device 202 to indicate the domain, or network entry point 305 with which it wishes to open wireless tunnel 325. In this example, the tunnel first reaches network router 315 which uses name server 307 to determine which network entry point 305 matches the domain provided. Multiple wireless tunnels can be opened from one wireless device 202 for redundancy, or to access different gateways and services on the network. Once the domain name is found, the tunnel is then extended to network entry point 305 and necessary resources are allocated at each of the nodes along the way. Network entry point 305 then uses address resolution component 335 (e.g., DHCP server 335) to allocate an IP address for wireless device 202. When an IP address has been allocated to wireless device 202 and communicated to gateway 340, information can then be forwarded from gateway 340 to wireless device 202.
Wireless tunnel 325 typically has a limited life, depending on wireless device's 202 coverage profile and activity. Wireless network 345 will tear down wireless tunnel 325 after a certain period of inactivity or out-of-coverage period, in order to recapture resources held by this wireless tunnel 325 for other users. The main reason for this is to reclaim the IP address temporarily reserved for wireless device 202 when wireless tunnel 325 was first opened. Once the IP address is lost and wireless tunnel 325 is torn down, gateway 340 loses all ability to initiate IP data packets to wireless device 202, whether over Transmission Control Protocol (TCP) or over User Datagram Protocol (UDP).
In the present disclosure, an IP-based wireless network (which is one specific type of wireless communication network) may include but is not limited to (1) a Code Division Multiple Access (CDMA) network that has been developed and operated by Qualcomm; (2) a General Packet Radio Service (GPRS) network for use in conjunction with Global System for Mobile Communications (GSM) network both developed by standards committee of European Conference of Postal and Telecommunications Administrations (CEPT); and (3) future third-generation (3G) networks like Enhanced Data rates for GSM Evolution (EDGE) and Universal Mobile Telecommunications System (UMTS). It is to be understood that although particular IP-based wireless networks have been described, techniques of the present disclosure could be utilized in any suitable type of wireless network. Note that the infrastructure shown and described in relation to
In the method of
Beginning at a start block 402 of
The processor maintains a character count of the number of characters in the message composition field (step 408 of
While the processor identifies the character count be less than the warning count value (“No” branch from step 410), the processor refrains from causing the number of allowed characters remaining for entry in the message to be presented in the display (step 414 of
Note further that, when the message is completed and transmission is desired, the processor will cause the message to be suitably formatted and transmitted via a wireless network through use of a Short. Message Service (SMS), or alternatively a Multimedia Messaging Service (MMS).
As described earlier above, each message may be constructed as one or more message segments, where the maximum number of characters permitted in a message is actually the maximum number of characters permitted in each message segment. In this case, the processor may maintain a message segment count of the number of message segments utilized for constructing or formatting the message. When the character count exceeds the maximum number of characters of the message segment, the processor operates to increment the message segment count and reset the character count (e.g. Char_Count=“0”). This process is described in more detail in relation to the method of
As described previously, the processor executes the messaging application for an end user to compose and transmit a new message from the communication device. In the technique, the processor maintains a character count (i.e. “Char_Count”), a message segment count (i.e. “Seg_Count”), and a remaining character count (“Rem_Count”). Char_Count is the current number of characters entered in the message composition field for a message segment. Seg_Count is the current number of message segments being utilized for constructing or formatting the message. Rem_Count is the current number of allowed characters remaining for entry in the message segment (e.g. Rem_Count=Max_Char_In_Seg−Char_Count). In this example, it will be assumed that the maximum number of characters permitted in a message segment (i.e. “Max_Char_In_Seg”) is one hundred and sixty four (164), the maximum number of message segments utilized for constructing or formatting a message (i.e. “Max_Seg_In_Msg”) is six (6), and the warning count value (i.e. “Warn_Count”) is one hundred and fifty four (154).
Beginning at a start block 422 of
During composition of the message, the user of the communication device may enter, via the user interface, one or more characters in the message composition field. In turn then, the processor may receive one or more character inputs in the message composition field (step 428 of
On the other hand in step 428, if the processor identifies a character update (to add, to delete, etc.), the processor updates the presentation in accordance with the added or deleted character (step 433 of
The processor identifies whether the character count is less than zero (step 436 of
If the character count is greater than or equal to zero in step 436 (i.e. normal condition), the processor identifies whether the character count is greater than the warning count value (e.g. Warn_Count) (step 442 of
On the other hand in step 442, if the character count is greater than the warning count value, then the processor identifies whether the character count is less than the maximum number of characters in the message segment (i.e. “Max_Char_In_Seg”) (step 448 of
The effect of steps 442, 444, 446, 448, 450, 452, and/or 454 is that the alert bar which includes remaining character count and/or message segment count is presented only when the character count is closely approaching the maximum count, for each message segment. Note that, in one variation on this method, the presentation includes the character count instead of the number of allowed characters remaining for entry.
On the other hand in step 448 of
If at step 464 the message segment count is greater than the maximum number of segments permitted in a message, then the processor will cause a switching of the current messaging mode to a different messaging mode (e.g. switch from SMS messaging mode to MMS messaging mode). Here, the processor sets the character count to the maximum count (maximum count=Max_Char_In_Seg×Max_Seg_In_Msg) (step 466 of FIG, 6), causes the current messaging mode to be switched to a different messaging mode (e.g. switches from SMS messaging mode to MMS messaging mode), and causes a messaging mode switching indication to be presented in the alert bar (step 470 of
However, in step 456, if the character count is greater than the maximum number of characters permitted in a message segment, then the processor identifies whether the character count is greater than a second warning count value (e.g. “Warn_Count2”) (step 458 of
The effect of steps 458, 470, and/or 472 is that the alert bar which includes remaining character count and/or message segment count is presented only when the character count is closely approaching the maximum count. The further effect of steps 458, 470, and/or 472 is that the alert bar is presented upon messaging mode switching plus a few characters of input.

Thus, methods and apparatus for use in providing presentations for the composition of messages having size limitations have been described. A communication device receives, via its user interface, one or more character inputs in a message composition field for a new message being composed. While a character count of the message is less than a warning count value, the device refrains from presenting the number of allowed characters remaining for entry in the message. On the other hand, while the character count is greater than or equal to the warning count value, the device causes the number of allowed characters remaining for entry in the message to be presented. The device then causes the message to be transmitted via a wireless network via a short message service (SMS). In one example, the number of allowed characters remaining for entry is provided in an alert bar, which is presented by being set in motion from an initial hidden position behind the message composition field to a final revealed position, with intermediate positions therebetween.
The above-described embodiments of disclosure are intended to be examples only. For example, the techniques may apply to other types of messages such as instant messages or email messages. Alterations, modifications, and variations may be effected to particular embodiments by those of skill in art without departing from scope of invention, which is defined solely by claims appended hereto.
