Full Text METHOD FOR OPERATING A PERSONAL
CELLULAR TELECOMMUNICATIONS DEVICE
Field of the Invention
The invention relates to the operation of cellular telecommunications
networks, and personal cellular telecommunications devices.
Background of the Invention
Global Networks for Mobile Communications (GSM) digital cellular
telecommunications networks have now been deployed alongside wireline
telecommunications networks in over a 100 countries. GSM supports a so-called
Short Message Service (SMS) functionality in two flavors: point-to-point for
sending a point-to-point message (SMS/PP) from a network operator to a single
personal cellular telecommunications device, and point-to-multipoint for sending
a Cell Broadcast (SMS/CB) inessage from a network operator to a plurality of
personal cellular telecommunications devices located in one or more cells. For
more details regarding the different classes of SMS messages, reference can be
made to ETSI TS 100 900 Version 7.2 (GSM 03.38 Version 7.2), the contents of
which are incorporated by reference.
In WO98/10604 entitled "Interactive Cell Broadcast Service", there is
illustrated and described a rnethod and apparatus for transmitting SMS/CB
display messages to subscribers who are prompted to respond by depressing a
pushbutton for immediately originating either a telephone call or an SMS/PP
message to an embedded callback number. One particular application of the
interactive cell broadcast service is for requesting a service which can then be
provided by so-called over the air programming. Each SMS/CB message is
displayed on the entire display screen either immediately upon its receipt, or
when requested by the user (see page 11, Tmes 27-29 of the specification,). Both
approaches severely limit the interactive cell broadcast service in terms of the
rate at which SMS/CB messages can be transmitted as follows. In the former,
immediately displaying SMS/CB messages on a display screen annoyingly
interrupts the operation of the device from the point of view of the subscriber
who would therefore be inclined to disable the service. And in the latter, storing
SMS/CB messages requires considerable memory resources, and requiring a user
to retrieve each SMS/CB message individually (and thereafter delete them
individually) is time consuming and battery wasteful.
Summary of the Invention
Broadly speaking, the present invention is directed toward the streaming of
mostly different content at least some interactive display messages on personal
cellular telecommunications devices for the benefit of subscribers for no more
than their occasional glancing at their personal cellular telecommunications
devices' display screens which they often do anyway, for example, to check the
time. The present invention can display both Point-To-Point (PTP) display
messages and Point-To-MultiPoint (PTMP) display messages but in the case that
PTP display messages and PTMP display messages are simultaneously
transmitted over their respective air interface channels, the former display
messages typically have a higher display priority than the latter such that they are
preferentially displayed.
The display messages are intended to have mostly different content
including inter alia news items, fmancial information, promotional offers, and the
like, in the form of alphanumeric messages, graphic messages, video clips, and
the like. Whilst some display messages will by their nature be repeated on a
regular basis, for example, display messages advertising a soft drink, the term
mostly different is intended to convey that identical display messages are not
display during consecutive time intervals of, say, between 1 minute and 5
minutes. At least some of the display messages are intended to be interactive in
the sense that a subscriber can automatically activate a point-to-point
transmission response mechanism from a dedicated response means integrally
provided in a display message. The existence of a dedicated response means does
not necessarily have to be indicated on a display message to a subscriber but can
be understood by him as being available a matter of course. A response
mechanism can be pushbutton activated, voice activated, or touchpad activated.
In the case of pushbutton activated response means, each response means may be
a dedicated "MORE INFO" key, or a key selectively dedicated for the response
means but otherwise a conventional key, for example, the key "*" as may appear
in a display message, for example, 'PRESS * FOR MORE INFO". The display
messages are preferably transmitted at a maximum rate of a new display message
about every 5 seconds on a so-called 24/7 basis i.e. all day every day, thereby, on
the one hand, rendering an interesting eye catching service of streaming display
messages but, on the other hand, still providing sufficient response time for a
subscriber to activate a response mechanism. Obviously, display messages can be
transmitted at slower rates, say, down to one display message about every 2
minutes, or even slower, say, one display message about every 5 minutes, and for
shorter periods, say, 10 minutes of display messages on the hour during peak
broadcasting hours only.
The display messages can occupy different regions of a display screen as
follows: First, they can replace a so-called "idle screen " typically occupying the
entire space of a display screen for displaying inter alia network related
information, for example, the name of an operator, time, signal strength, battery
strength, the presence of one or more voice messages and/or SMS messages
stored in a permanent storage buffer prior to their deletion, and the like. And
second, they can occupy a portion of a split screen, for example, a horizontally
disposed banner portion, also typically having a major portion for normally
displaying an idle screen. In the latter instance, the banner portion may be a
permanent feature of a display screen or it may be replaced together with the first
portion in a similar manner to the first instance on the invoking of a non-idle
activity specific screen having at least some indication of an ongoing activity
including inter alia the entire process from establishment to tear down of a voice
call irrespective of whether a subscriber is the originating party or the receiving
party, and any other subscriber initiated activity, for example, retrieving an item
stored in memory, playing a game, writing a memo, and the like. An exemplary
"idle screen " within the spirit of the present invention is displayed in the so-
called User Idle Screen Available Event (see 3GPP TS 31.111 V4.0.0 3rd
Generation Partnership Project; Technical Specification Group Terminals; USIM
Application Toolkit (USAT) (Release 4)).
The envisaged streaming of display messages provides a most convenient
platform for m-commerce applications, and in particular interactive m-commerce
applications catering for a wide range of ages, lifestyles, and the like. It is
believed that its exposure to the general public will be far greater than thait of
conventional radio, television and cable broadcasting services taking into
consideration the ubiquity of personal cellular telecommunications devices, the
fact that most subscribers now take their personal cellular telecommunications
devices wherever they go, and the fact that they are in idle mode for most of the
time that they are powered on. Moreover, unlike conventional broadcasting
services which are at best regional services, smce each BTS can be individually
addressed, the present invention readily facilitates the transmitting of far more
location specific content down to the granularity of a single BTS than hitherto
achievable. In this connection, additional BTSs can also be readily deployed for
the sole purpose of transmitting specific content at particular locations.

Detailed Description of the Drawings
Figure 1 shows a cellular telecommunications network 1 capable of
transmitting a multi-programming channel 24/7 cellular broadcasting service to a
plurality of individually addressable BTSs 2 each providing bidirectional signal
coverage over a predefined geographical area ranging from so-called typically
indoor pico cells each covering a few square meters through so-called micro cells
each covering anywhere from a few tens to a few hundreds of square meters upto
cells covering several square kilometers. The BTSs 2 are each capable of
transmitting Point-To-MultiPoint (PTMP) display messages and Point-To-Point
(PTP) display messages for streaming mostly different content, mostly interactive
display messages on personal cellular telecommunications devices 3. The PTMP
display messages are dispatched from a Point-To-MultiPoint Display Message
Dispatcher 4 and the PTP display messages are dispatched from a Point-To-Point
Display Message Dispatcher 6. Both the PTMP display messages and the PTP
display messages originate at a Display Message Input Entity 7. The devices 3
include inter alia simple handset phones, smartphones, combined PDA/phones,
combined MPS music players/phones, and the like.
Figure 1 also shows two exemplary successive time-sensitive display
messages displayed in a screen saver-like manner replacing a normally displayed
idle screen. The display messages include "NASDAQ DROPS 10% PRESS SND
FOR DETAILS" display at 9:00 and "NASDAQ JUMPS 20%" displayed at 9:01.
The 9:00 display message is an example of a display message prompting a
subscriber as to the action required by him to obtain additional information from
an information provider. Against this, the 9:01 display message is an example of
a display message which does not prompt a subscriber as to which action is needs
to take to obtain additional information since he is already cognizant of the fact
that pressing the SND key will automatically connect him to a suitable
information service. Figure 2 shows a display message prompting a subscriber to
activate a point-to-point transmission response mechanism from the list of: a
voice call; an SMS; a data session, for example, an Internet browsing session, a
SIM browsing session, and the like; e-mail; and a facsimile transmission.
Figure 3 shows that a cellular broadcasting service can include a non-
geocoded or nationwide programming channel, and one or more geocoded
programming channels for transmitting streams of PTMP and PTP display
messages from logical groups of BTSs each including one or more BTSs. Each
logical group of BTSs either covers an extended contiguous geographical area,
for example, a metropolitan area or geographical areas sharing a common theme,
for example, schools, along highways, and the like. The programming channels
typically include time slots for transmitting programs which are either common
to both the nationwide programming channel and the geocoded programming
channels, for example, the News, or dedicated to a particular logical group of
BTSs, for example, an Anti-drug program for transmission at BTSs of the logical
group of BTSs which cover schools, Traffic updates for transmission at BTSs of
the logical group of BTSs which cover major highways, and the like. Also, a
geocoded programming channel can be itself segmented to two or more so-called
geocoded programming sub-channels each to be transmitted at a subset of the
BTSs of the logical group of BTSs associated with the geocoded programming
channel. For example, the school programming channel can be segmented to an
elementary school programming sub-channel, a high school programming sub-
channel, and a college programming sub-channel.
It should be noted that a BTS may be assigned to one or more geocoded
progranmiing channels depending on its location, for example, a BTS which
covers a geographical area containing both a football stadium and a shopping
mall in most likelihood will be assigned to both a sports programming channel
and a shopping programming channel of the cellular broadcasting service to
maximize its efficacy in terms of geocoded content. In such instance, a
progranmiing channel allocation scheme 8 can be provided for determining
which stream of PTMP or PTP display messages should be displayed at each
BTS. The schemes can be time dependent, for example, sports programming
channel be transmitted during a time interval starting 2 hours before the start of a
football match and ending 2 hours after the football match ends, the shopping
programming channel be transmitted at other times when available for
transmission, and the nationwide programming channel be transmitted at all other
times that neither the sports programming channel nor the shopping
programming channel are available for transmission.
Figure 4 shows a staggered sequence of display messages for advertising
tickets for a football game to take place at a stadium over progressively smaller
geographical areas and at progressively lower prices on the same day as the game
assuming that unsold tickets still available. Such display messages may be either
PTMP display messages, or PTP display messages transmitted to subscribers
listed in the fan club of the stadium's home team. The geographical areas are
usually centered around the stadium, and are such that a subscriber can still reach
the stadium in time for kick-off. Such an advertising campaign can be readily
applied to other items with either a fixed "sellby" date or a limited stock, for
example, for advertising a clearance sale of consumer items at a retail outlet.
Figure 5 shows a GSM based personal cellular telecommunications device
3 including an antenna 11, a transceiver 12, a controller 13 providing a clock
time denoted Tclock, a SIM card 14 (constituting a smart card), a subscriber
interface 16, and a loudspeaker 17. The subscriber interface 16 includes a
display screen 18, a keypad 19, and a microphone 21. The display screen 18 may
be a touchpad. The device 3 may also include a voice recognition capability 22
for supporting voice activated activities including inter alia dialing, invoking a
response mechanism, and the like. The SIM card 14 includes two fixed size
dynamic storage buffers 23 and 24 for temporarily storing PTMP display
messages and FTP display messages, respectively, passed thereto by the
controller 13 prior to their being automatically discarded in accordance with a
display message discard scheme irrespective of their having been displayed or
not. The entire handling of a display message from its receipt through to its
being automatically discarded is a completely silent process irrespective of
whether the display message is displayed or not.
The operation of the screen saver-like application in respect of each of the
dynamic storage buffers 23 and 24 is as follows: The display message discard
scheme automatically discards undisplayed display messages from a dynamic
storage buffer on a First In First Out basis, thereby ensuring that the dynamic
storage buffer only stores the most recently received display messages, and
automatically discards display messages after they are displayed. In addition,
assuming that the display screen is available for display of a display message,
immediately before a display message is actually displayed, the following checks
are made: First, since display messages may be incomplete due to any one of
several occurrences, for example, air interface interference, hand over between
cells, and the like, each display message is checked for completeness and if it is
found to be incomplete, it is automatically discarded. Second, since at least some
of the display messages are time sensitive, each display message is checked for its
not being out-of-date by its satisfying the following condition: TCLOCK-
TRECEIPT and TDISCARD is a predetermined time interval, for example, three minutes, which
is necessary.
Figures 7A-7D show different modes of streaming of display messages on
a personal cellular telecommunications device having a split screen display screen
26 including a major portion 27, and a minor horizontal banner portion 28.
Figure 7A shows that the major portion 27 displays an idle screen whilst the
banner portion 28 shows a stream of at least some interactive display messages
whilst Figure 7B shows that the display messages are only displayed on the
banner portion 28 when the idle screen is displayed on the major portion 27.
Figure 7C shows that the banner portion 28 is a permanent feature of the split
screen display screen 26 either occupying only a portion thereof, or that it can be
extended to include the entire display screen 26 instead of the major portion 27
displaying an idle screen (see Figure 7D).
