## Background
RELATED APPLICATIONS
This application claims priority under 35 U.S.C. §119 based on U.S. Provisional Application Ser. No. 60/778,413, filed Mar. 3, 2006, the disclosure of which is incorporated herein by reference.


TECHNICAL FIELD OF THE INVENTION
The invention relates in general to communication of location information. More particularly, the invention relates to obtaining and/or providing location descriptor information.
DESCRIPTION OF RELATED ART
Since mobile phones no longer are used only for making phone calls, but for communicating information messages of many kinds including, SMS, MMS, IMS, etc., the mobile phones are seldom switched off.
It is therefore important to be able to set a user's accessibility, such as from whom a user can accept a phone call and with whom a user presently does not wish to communicate. Presently, entries about one's availability status may be made into the calendar of a mobile phone, which calendar of course may be subject to synchronization with a corresponding calendar in another computer system, typically a personal computer or a larger server based computer system.
In some instances, a user of a one mobile phone can gain information about the geographical position of another mobile phone being used by another user. If the user does not have sufficient knowledge about the geographical position, however, he or she may fail to take advantage of such geographical position information, such as using it adapt the volume of a voice call to the callee. In order to make use of information without sufficient prior knowledge of geographical position information, knowledge or supplementary information may have to be gained in a further processing step by the user. This is an inconvenience to the user seeking such information.
There is hence a need to overcome the limitations of such prior art technique and to provide a technique with which a user of a portable communication device can automatically gain access to information about the location of another portable communication device, which information is easily and quickly understandable.

DETAILED DESCRIPTION OF THE EMBODIMENTS
Aspects of the invention are directed toward gaining knowledge about the geographical location circumstances with respect to a user of a portable communication device. For example, in aspects of the invention, location information of a first portable communication device, such as a mobile phone, may be available to a network service provider and/or accessible to the network service provider. One example of such location information may identify where a first mobile phone is situated, such as a city, state and/or country, or more specific information, such as a street address within a city, a location such as an airport, train station, shopping mall, etc. Upon a request from a user of a second portable communication device, such location information may be automatically sent to user of second portable communication device. Gaining readily understandable information that a friend/colleague is in, for example, Istanbul, Turkey and that the local time is 4:30 AM, may be a very useful piece of information Indirectly, the information may also be used to let a user know that a friend/colleague is not in transit to a destination, but has arrived at his/her destination (Istanbul in this example).
With reference to FIGS. 1 and 2, schematically showing a portable communication device 100, according to an exemplary embodiment and a flow chart of a method of obtaining location descriptor information according to an exemplary embodiment respectively, the invention is now explained in more detail.
According to one embodiment, the portable communication device 100 comprises a user input unit 102, a transceiving unit 104, a memory unit 106, a control unit 108, and an information presentation unit 110. As shown in FIG. 1, the control unit 108 is connected to all other units (i.e., user input unit 102, transceiving unit 104, memory unit 106, and information presentation unit 110). Moreover, the memory unit 106 may be connected to the transceiving unit 104 and to the information presentation unit 110, according to this embodiment.
Reference will also be given to FIGS. 3 and 4, displaying a portable communication 30 device in the form of a cellular phone and a schematic diagram illustrating an exemplary communication system 40 communicating location descriptor information, respectively. System 40 includes a second portable communication device in the form of a mobile phone 42, a network service provider 44 of the second portable communication device 42, a network service provider in form of an electronic communication device or a communication server 46 (also referred to as a network server 46), and a first portable communication device 48 in the form of a mobile phone, according to one exemplary embodiment. In an exemplary embodiment, portable communication devices 30, 42 and 48 may be configured in a similar manner as portable communication device 100.
The method for which the flow chart is presented in FIG. 2 begins with the step of detecting a request for description of the location of a first mobile phone 48, being one example of a portable communication device, by a second mobile phone 42, again being one example of a portable communication device (step 202). In dependence of user input via the user input unit 102, this request for description of the location may be detected by the control unit 108.
According to an alternative embodiment, the step of detecting a request for description of the location may be performed elsewhere, such as for instance by the network service provider 44 of the second mobile phone 42. In this implementation, with respect to the second mobile phone 42, the request for description of the location of mobile phone 48 may be considered to be automatically generated since it is generated by the network service provider 44 and no user input associated with mobile phone 42 is required. In other words, in this embodiment, the request is performed independent of user input via the user input unit 102 of the second mobile phone 42.
Having requested a description of the location of the first mobile phone 48 in step 202, the request for the location description is sent to a network server 46 of the first mobile phone 48 (step 204). This step may include sending the request to a particular server, such as server 46, that is able to obtain relevant location related information associated with the first mobile phone 48.
After executing step 204, the method of obtaining location description information regarding the location of mobile phone 48 (for which the flow chart is presented in FIG. 2) includes awaiting a positive response to the sent request. For this reason and to follow the processing of the request as performed above, the method of providing description of the location of the first mobile phone 48 will now be discussed with respect to the flow chart of FIG. 5.
Referring to FIG. 5, the method may begin by receiving the request for description of the location of the first mobile phone 48, wherein the network server 46 receives the request from the second mobile phone 42 (act 502), according to one exemplary embodiment. For clarity it should be mentioned that the request being received at this step (i.e., step 502), is the request that was sent in step 204 in the method of obtaining location information in FIG. 2.
According to an alternative embodiment, the request received by the network server 46 in step 502 may be received from the network service provider 44 of the second mobile phone 42. The request for location information may thus originate from different sites, as was indicated above in connection with the flow chart of FIG. 2.
According to one embodiment, having received the request for location description information in step 502, the network server 46 of the first mobile phone 48 determines whether the second mobile phone 42 has been given permission by the first mobile phone 48 to access location information of the first mobile phone 48 (step 504).
User settings of various types by which permission may be granted to, for example, a subgroup of a user's contacts may be used. Alternatively, granting permission to access location information during working hours for one subgroup and permission to access location information during a different time interval by a second subgroup, such as, for example, a 24-hour basis, may be used to mention a few examples only
If it is determined in step 504, by the network server 46, that the second mobile phone 42 is not granted permission to access location information of the first mobile phone 48, the session may end (step 506).
If, however, it is determined by the network server 46 in step 504 that the second mobile phone 42 is granted permission to access location information of the first mobile phone 48, the location of the first mobile phone 48 may be determined (step 508), preferably by the network server 46.
The network server 46 typically has access to location information of the first mobile phone 48, but may have to determine such information more accurately depending on the precision of location information that is requested, according to an alternative embodiment.
Determining geographical position and location per se is well known to the skilled person and includes a number of ways to perform such a task. Such steps, therefore, will not be described in detail herein in order to not unduly obscure the thrust of the invention. It should also be understood that aspects of the invention are not limited to any particular method of determining location/geographical information.
Having determined the location of the first mobile phone 48 in step 508, information about the local time for that location of the first mobile phone may be obtained (step 510). With information about the location of the first mobile phone 48 and the local time of the location of which information was obtained, an image file may be obtained describing the location, preferably at that time of the day (step 512). For example, the image file may describe and/or illustrate how the location may look at 7:30 AM, such as an image file illustrating the sun coming up at that particular location. Within this step (i.e., step 512), explicit information about the time may also be obtained. That is, the local time at the particular location may be obtained. According to an exemplary embodiment this step may be performed by the network server 46.
However, according to another embodiment, location information may be received by other servers or networks, such as local area networks or hot spots, providing local descriptions of the location of the first mobile phone 48. This may be on request from the network server 46 or may be executed without a request from the network server 46, while the first mobile phone 48 is within the reach of the local area network of the hot spot, for instance. According to yet a different embodiment location descriptions may comprise moving pictures, such as video clips, associated with the particular location. This may include live video clips of the particular location or stored video clips associated with the particular location.
Alternatively, in some implementations, description information may be received from the user of the first mobile phone 48, whereby such descriptions may be stored, for example, in the network server 46. In such implementations, the particular descriptions to be presented to the user of the second mobile phone 42 may be descriptions that the user of the first mobile phone 48 would like seekers of location information, such as users of second mobile phone 42, to experience. For example, the description may include (for the example above in which the user is in Istanbul, Turkey) “I'm here in Istanbul, Turkey having a good vacation” or any other particular description information that the user of first mobile phone 48 would like to present to another mobile phone user, such as the user of second mobile phone 42.
In addition, interactive video files comprising audio and video information may similarly be obtained as the location descriptor information of the first mobile phone 48, according to another embodiment of the present invention. The interactive video files may be provided in addition to text providing location description information or may be provided without accompanying text providing a location descriptor.
Having obtained a description in step 512, containing location information and preferably including explicit time information, the step of sending the image file and the local time information to the second mobile phone 42 is executed (step 514). According to an alternative implementation, the image and time information may be sent to the network service provider 44 or a network server associated with the second mobile phone 42, for subsequent sending to the second mobile phone 42.
Returning to FIG. 2, as location information has been sent, the method of obtaining location descriptor information or description about the location (schematically presented in the flow chart in FIG. 2), an image file describing the location of the first mobile phone 48 may be received from, for example, the network server 46 and/or network service provider 44 (step 206). This information may be provided when the request for information was successfully processed by the server 46.
In the case the second mobile phone 42 was not granted permission to access location information of the first mobile phone 48, a time out may be executed and the method of providing is ended, as earlier described in connection with step 506.
Having received from either the network service provider 44 of the second mobile phone 42 of directly from the network server 46 of the first mobile phone 48, an image file describing the location of the first mobile phone 48, the second mobile phone 42 presents and/or displays the image file to a user of second mobile phone 42 (step 208).
Presenting the image file may preferably be performed by using the information presentation unit 110 of the portable communication device 100 as shown in FIG. 1. The user of the second mobile phone 42 can thereby obtain information about the location circumstances of the user of the first mobile phone 48. For example, the user of the second mobile phone 42 may view the image file, which may include a video clip and/or message as described above. In some implementations, the video clip and/or message may be personalized by the user of first mobile phone 48. For example, the video clip may be a short video clip taken by the user of the first mobile phone 48 along with audio provided by the user of the first mobile phone 48. Alternatively, the video clip may be a pre-stored video clip associated with the location of the user of the first mobile phone 48.
In some embodiments consistent with the invention, the location description information provided to a user of a communication device, such as second mobile phone 42 may be provided prior to setting up a voice and/or video communication session with a user of for example, first mobile phone 48. That is, the location information may be provided without the user of second mobile phone 42 actually placing and/or completing a call to the user of first mobile phone 42. In this manner, if the user of second mobile phone 42 determines that the user of the first mobile phone 48 is located at a train station, for example, the user of second mobile phone 42 may speak in a louder voice to the user of first mobile phone 48 when a call to the first mobile phone 48 is completed. In other implementations, the location information may be provided concurrently with the completion of a call to the first mobile phone 48.
According to one aspect consistent with the invention, a computer program product, for instance in the form of a CD-ROM disc, may be provided. The computer program product may comprise a computer readable medium having thereon computer readable code means, to make a computer or a device execute steps of a method consistent with the invention, when said program code means is loaded in the computer or the device.
In addition, FIG. 7 schematically presents one example of information that may be presented via an information presentation unit 110 of a mobile phone. According to this embodiment, the view provided by the information presentation unit 110 may schematically be visualized as FIG. 7, where the information presentation unit 110 typically is a display, such as a liquid crystal display (LCD) or some other display of a mobile phone. In this example, the image information (e.g., is denoted by 72 and the combined explicit time information together with location information which both were received, is denoted with 74, being “TOKYO, 3 AM” in this example.
The image information 72 may be an image file, a video clip, etc., as described above. Other explicit information, such as names, as well as time information showing a clock, may be incorporated in the image information, in the form of one or several still or moving images/pictures.
For example, according to one embodiment, location descriptor information may be presented by the information presentation unit 110 within the contact application above or below the label “LOCATION”. In the example of FIG. 7, the contact information belongs to “BERTIL PERSSON”.
According to a variation of the embodiment, the location descriptor information may be presented in a calendar application, in which “PRESENCE” already may be available as one option of obtaining availability information.
In yet a different alternative, an application combining the contact and the calendar, may be provided, in which location descriptor information of different kinds may be given emphasis.
It is emphasized that aspects consistent with the invention may be varied in many ways, of which the alternative embodiments described herein are only a few examples. These different embodiments are hence non-limiting examples. The scope of this present invention, however, is only limited by the claims and their equivalents.
For example, according to yet a different embodiment, the portable communication device used in implementations described above with respect to receiving and/or providing location information may comprise a personal digital assistant (PDA) or a hand held communication device, such as a combined MP3-camera-communication device, to mention a few examples only.
Aspects of the invention have thus been described with respect to methods for obtaining and/or providing location descriptor information, a portable communication device, an electronic communication device and computer program products, sharing the following overall advantages of providing means to quickly determine where a user of a portable communication device is located. In addition, some aspects of the invention advantageously provide for obtaining or receiving location descriptor information prior to setting up a voice or video communication session between parties.
