Definitions

  • the present invention relates to a method of call management in a wireless information device, and in particular to a method of managing calls in such devices using a time zone based call handling system.
  • wireless information device used in this patent specification should be expansively construed to cover any kind of device with one or two way wireless information capabilities and includes without limitation radio telephones, smart phones, communicators, personal computers, computers and application specific devices. It includes devices able to communicate in any manner over any kind of network, such as GSM or UMTS, CDMA and WCDMA mobile radio, Bluetooth, IrDA etc.
  • the present invention addresses the problems associated with inconveniently timed or expensive incoming phone calls, specifically those receiving on mobile communications devices while roaming away from a home network.
  • lolan Software offer products for Symbian OS operating system handsets which are able to screen calls and filter them based on caller identity information (CID). This process is described in greater detail at http://www.iolansoftware.fi/products.html. Other blocking solutions aimed at advanced phones are possible, such as limiting calls to certain times of the day.
  • CID caller identity information
  • Non blocking mechanisms are also available, such as relying on presence information by which a user can publish or broadcast his or her availability (see http://www.openmobilealliance.org/tech/wg_committees/pag.html for more information on presence).
  • Presence facility is discussed further below.
  • a method of managing incoming telephone calls on a wireless communications device comprising a. maintaining a first record comprising the normal home network and time zone of the user of the device; b. maintaining a further record comprising the network and time zone in which the device is operating; and c. using the first and further records to manage incoming calls to the device.
  • a telecommunications device arranged to implement a method according to the first aspect.
  • a telephone network arranged to implement a method according to the first aspect.
  • an operating system arranged to cause a telecommunications device to operate in accordance with a method of the first aspect.
  • Figure 1 shows, schematically, how a call handling method according to the present invention may be implemented
  • FIG. 2 shows a call handling method in accordance with the present invention
  • Figure 3 shows an embodiment of an out of hours decision tree for use with the method of figure 2;
  • Figure 4 shows an embodiment of a caller identification decision tree for use with the method of figure 2;
  • Figure 5 shows an embodiment of a call action decision tree for use with the method of figure 2;
  • Figure 6 shows an embodiment of an automatic call handling system according to the present invention which accounts for a user of a call handling device moving between time zones.
  • the system of the present invention arises from an analysis of the concerns outlined above for existing call handling and is based on the perception that a solution to these concerns should be based on the same methodology as a caller would have used in deciding whether to proceed with the call or not, had the caller known the implications arising from the location of the recipient.
  • a further desirable characteristic of such a system is that it should be automatic; this means that it should require no active or special intervention on the part of the caller or of the recipient.
  • a highly desirable characteristic of such an automatic method is that it should also be intelligently adaptive; this means that it should not attempt to interfere with the process of making calls when it is unlikely that the problems associated with roaming will need to be considered by the caller. Any automatic method that interferes with normal non-problematic calls is unacceptable from the user's point of view. As described above in connection with using presence, it is not acceptable to solve a problem for a relatively small proportion of calls made to a relatively small proportion of users by making it more difficult, expensive and time consuming for all users to make all calls.
  • the present invention fulfils all the criteria for a good solution to the problems outlined above. It consists of a method for call management for a mobile telephone device, such that it is possible
  • Figure 1 shows the general call handling method context of the present invention where it can be seen that the invention can be implemented entirely within the network infrastructure, where it is transparent to both the originating terminal and the receiving terminal. Alternatively, the invention may be implemented entirely within the receiving terminal, in which case it is transparent to the network. It should be noted that with either implementation, the invention is completely independent of the nature and type of the originating terminal.
  • This device is provided with a framework or system enabling the user to define a set of criteria on his/her telephone that will govern the handling of incoming calls according to whether the device is operating in its home network or in its home time zone. The user is able to specify that incoming calls can be filtered depending a number of criteria which may include the following:
  • FIG. 2 An embodiment of this basic call handling method is shown in figure 2.
  • the method shown in figure 2 includes three decision trees through which an incoming call originating in any fixed or mobile network must pass before being connected to a recipient device. As can be seen from figure 2, these three decision trees are called o 'out of hours' decision tree o 'caller identification' decision tree o 'call action' decision tree.
  • Whether or not an incoming call is connected to a recipient device, rejected, or diverted is dependent on the settings of the recipient device, as defined by the user of that device, and the output of any of the above decision trees. In all cases (connection, diversion or rejection) a record is maintained of the caller ID, call details, and action taken for use in future decisions which might need to be made regarding the recipient device.
  • the out of hours decision tree is shown in detail in figure 3.
  • the process decides whether or not the time is determined to be "out of hours"; i.e. whether or not the actual time is acceptable for the call to be passed through to the recipient device.
  • the call is connected as normal. However, if the time is considered to be out of hours, the process continues to the "caller identification" decision tree, as shown in figure 4.
  • the system In this stage of the process, the system is seeking to determine whether or not the caller falls within a category of callers which the device user has specified as requiring a level of service other than straightforward call rejection because the incoming call is in an "out of hours" time frame for the recipient device user.
  • the system first considers whether the caller is in the phone book of the recipient device. If the answer is 'yes', the call is connected. If the answer is 'no', it is next determined whether the caller identity matches a 'white list' of callers stored in the system.
  • the call is connected, but if the answer is 'no' it is then determined whether or not the caller has received previously information regarding the time zone of the recipient. If the answer is 'yes' , the call is connected because the system considers that because the caller is aware of the recipient time zone and is still trying to connect, the call content must be considered sufficiently urgent by the caller to warrant connection even when the time zone consideration has been taken into account. If the caller has not previously received the recipient time zone information, the call request is passed to the "call action" decision tree, which is shown in figure 5.
  • the incoming call has been determined to be out of hours and it has not been accepted by any of the previous decision making processes. If the device user has configured the system to reject all such calls, the call is rejected, with a message and/or other notification, such as an SMS message, being sent to the caller.
  • a message and/or other notification such as an SMS message
  • the user has not configured rejection of all such calls, it is then determined whether the user has optionally configured diversion of all such calls. If the answer is 'yes' the incoming call is diverted to voicemail, or another number as has been decided by the user, as shown in figure 5.
  • the caller is presented with options on how to proceed, i.e. connect, divert, or end the call, with or without a message or notification. If the user has not configured "caller decides" then the network or recipient device may apply user defaults to handle the incoming call.
  • NITZ Network Identity and Time Zone
  • the current time zone is the same as the home time zone but for the device not to be in the home network. Users roaming in places where several contiguous countries share identical time zones (e.g. within Europe) will often find this, as will users roaming any international borders in a north/south direction (e.g. between the US and Canada). It is also possible for the home network to remain the same but for the time zone to be different; this can be the case when traveling in a large country with national phone networks, such as the USA, Australia or Russia.
  • the essence of this invention lies not in the retrieval of the NITZ data from the network, but in the comparison of this data with the data previously recorded by the user concerning the home time zone and home network. If both the current time zone and current network are identical to the home time zone and the home network, then no additional call management steps need to be taken.
  • the data is automatically collated (either in the network infrastructure or the handset) and submitted to a decision tree.
  • This decision tree would take into account, for example, the time that the call was being received; clearly, there would be a case for a call arriving at 0300 local time to be treated differently to a call arriving at 1500 local time. Other types of data that the decision tree may selectively take into account is discussed below.
  • option 1 is a blanket blocking mechanism and hence may be regarded as unsatisfactory.
  • Option 2 may also be regarded as unsatisfactory because, in essence, it is also a blanket blocking mechanism, but provides some feedback information to the caller as to why the call has not been connected as expected.
  • option 3 provides a solution to the concerns outlined above because what it does is to again make possible the mechanism of reliance on the caller's good sense.
  • caller identification which is normally provided by the network.
  • the prior art referred to above from lolan software teaches how this data can be used as a method of screening incoming calls.
  • the lolan software does not disclose or suggest the possibility of combining CID information with the comparison of NITZ data, as enabled by the present invention.
  • option 2 rejects calls with a message to the caller indicating that the recipient is either not on the home network or is in a different time zone, or both.
  • the telephone device is enabled to keep a record of the identity of callers to whom the message has been already been relayed. The device will then automatically be able to discriminate between callers who are aware of the necessary information needed in order to judge whether their particular call is inconvenient or expensive, and those who are unaware of this information.
  • the message going out to the caller can then be amended to tell the particular caller that if he/she wishes to continue with the call, he/she should redial, in which case the device will know that some judgment has been applied by the caller in calling again, and thus that this further call from that caller can be relied on and passed through to the recipient.
  • entries in the record may be time-expired, such that if a caller calls back relatively quickly, i.e. before being time expired, the call is passed through; but if the caller calls back a day later, i.e. after being time expired, then the original message is played and the call is again rejected.
  • option 3 above could be modified by utilising CID data.
  • the caller record time-expiry strategy could be used in a way such that callers who had previously received the auto-answer message could be treated as 'trustworthy' callers, so that the second call from that caller, and possibly all subsequent calls within a predefined time period, may be passed through to the recipient without the message intercept.
  • the message given to the caller may be either a standard message or one provided by the user of the mobile telephone device. Messages may also be customized using caller ID; for example, the country location and hence the probable native language of the caller may be identified, so that, for example, calls from New York can be presented with a message in English, calls from Shanghai can be presented with a message in Mandarin and calls from Paris can be presented with a message in French.
  • caller ID for example, the country location and hence the probable native language of the caller may be identified, so that, for example, calls from New York can be presented with a message in English, calls from Shanghai can be presented with a message in Mandarin and calls from Paris can be presented with a message in French.
  • This method may be preferable to options 2 or 3 on security grounds if the telephone user does not wish it to be known by any caller that he/she is roaming, and therefore likely to be away from home, but nevertheless still wants protection against inconvenient or expensive incoming calls from those callers most likely to try contact.
  • a process for the automatic control of call handling according to the present invention is shown in figure 6. From the NITZ data of the time zone of the recipient device, the system is able to determine when the user has moved from one time zone to another. If the user has moved from the home time zone to a time zone other than the home zone, the timezone based call handling system can be automatically enabled. Likewise, if it is sensed that the user has returned to the home time zone, the system can be disabled, as shown in figure 6.
  • callers who have called the user when in the previous time zone are sent updated information notifying of the user's new time zone, and the caller list can be updated and entries removed as appropriate. For example, a caller who was local to the previous time zone may have been listed as a caller whose calls were connected because the caller was located in the same time zone as the user. But, because this caller is now in a different time zone, the decision tree processes might be considered appropriate to apply because of the time zone difference arising from the user moving time zones.
  • the list of callers may be automatically deleted from the telephone device once the user has returned to his/her home network and home time zone.
  • text messages or text messages or voicemails could be sent to all those numbers on the list notifying them that the user of the device was once again in 'home' territory.
  • the call management system of the present invention is provided with the additional benefit of a self-cancellation ability.
  • caller ID can also be used to refine the method used in traversing the decision tree referred to above.
  • the CID can be matched against a database of area codes and time zones held on the device, and where the call is detected as being from a person in the same time zone, the decision tree may decide to pass the call through to the device user.
  • the decision tree may decide to pass the call through to the device user.
  • a call is received at 3am when the caller is asleep in bed, but is coming from someone for whom the local time is also the middle of the night, it might be decided that the judgment of the caller in making the call should be trusted and hence the call subject must be of sufficient importance to cause the caller to call at that time.
  • the call is passed through to the device user.
  • Complex decision trees can be built up using many different sources of data in addition to the ones already described, such as where the caller is located geographically, whether the caller as well as the recipient is also roaming, whether the caller is already in the contacts list or address book of the phone, how much the call is going to cost etc.
  • There could also be additional special cases programmed into the device such as a call originating from a phone from the same original time zone but currently roaming in the same time zone as the recipient and which is also in the address book of the phone; in this instance it might be assume that such a call is from a traveling companion of the user and therefore passed to the device.
  • Another useful special case may be to unreservedly allow incoming calls from numbers to which the device had made outgoing calls while in the current network and time zone.
  • this invention may be implemented by allowing users to input such data, either in whole or in part, manually either via their telephones or some other mechanism. Although this is not a preferred embodiment (as it is neither automatic nor as failure-proof) it is certainly possible.
  • This invention is not limited to any particular type of user interface for its implementation, which could vary from using dialogues or checkboxes on the device itself to manual setup by a skilled operator using data provided by the user over a voice link.
  • the present invention discloses a method of managing potentially incoming calls on mobile phones which may be roaming away from their home network and home time zone, based on a system which maintains a record of both the normal home network and time zone of the user of the phone and also a record of the network and time zone in which it is operating; a comparison of these records, possibly in conjunction with other relevant information available to the device, is used as input into the incoming call management system, which then takes appropriate action.
  • a call received at an antisocial time in the user's current location can be answered automatically with a recorded message being played to the caller specifying the time zone in which the recipient is currently located, perhaps along with the local time, perhaps in the language of the caller, with an option to allow the caller to either ring off without disturbing the recipient, divert to voicemail, or continue with the call if still considered urgent with the information then known to the caller.

Abstract

La présente invention se rapporte à un procédé de gestion d'appels entrant sur des téléphones mobiles qui peuvent être itinérants par rapport à leur réseau de rattachement et à leur fuseau horaire de rattachement. Des enregistrements sont tenus à jour à la fois pour le réseau de rattachement normal et le fuseau horaire normal de l'utilisateur du dispositif ainsi que pour le réseau et le fuseau horaire dans lesquels le dispositif fonctionne. Une comparaison de ces enregistrements, éventuellement en association à d'autres informations appropriées telles que des informations d'identité d'appelant (CID) ou les informations relatives au carnet d'adresses et aux contacts de l'utilisateur, est utilisée pour la gestion des appels entrant. Par exemple, un appel reçu à une heure antisociale au niveau de la localisation courante de l'utilisateur n'est pas transmise à l'utilisateur, un message enregistré étant alors diffusé à l'appelant, de préférence dans la langue de l'appelant, spécifiant que le fuseau horaire dans lequel l'utilisateur se trouve à cet instant, ainsi que leur local. L'appelant peut alors mettre fin à l'appel sans déranger le destinataire, se diriger vers une messagerie locale ou insister pour appeler s'il considère l'appel suffisamment urgent en fonction des informations alors connues de lui. Ce système de gestion des appels peut procéder à une annulation automatique lorsque l'utilisateur revient vers le réseau et le fuseau horaire de rattachement.
