Abstract:
Ephemeris data is downloaded intelligently to a GPS-enabled wireless communications device based on user activity rather than at fixed predetermined intervals. Ephemeris data can be downloaded to enable both Aided GPS and Assisted GPS. The device can download ephemeris data based on the frequency of requests into an API communicating with a GPS driver, based on the detection of a new network, or a change in time zone of the network time. Intelligent, adaptive downloading of ephemeris optimizes the usage of bandwidth and the data charge to the user while ensuring that ephemeris data is cached to provide assistance for location-based services such as turn-based navigation.

Abstract:
A processor-implemented method of operating a mobile communication device operable to execute one or more communication applications includes issuing a query for contact data over a communication network, creating a contact resolution object, receiving contact data responsive to the query over the communication network, the contact data comprising communication contact data for the one or more communication applications, associating the contact data received with the contact resolution object, and resolving the contact resolution object to select communication contact data.
Abstract:
A method of displaying a map on a portable electronic device entails requesting map data that includes label data for at least one map label for a map feature known alternatively by a first name and a second name. The method further involves determining, based on a predetermined criterion, which of the first name and the second name is to be displayed on the portable electronic device. The predetermined criterion may be, for example, the current location of the device, a carrier identifier, or a personal identifier containing geographically relevant information from which a preferred map label may be inferred.

Abstract:
A method in a wireless communications device for transmitting current location information representing a current location of the wireless communications device. The method entails, from within a communication application executing on a processor of the wireless communications device, causing the wireless communications device to obtain the current location information representing the current location of the wireless communications device, including the current location information in a communication generated from within the communication application, and transmitting the communication that includes the current location information. The method optionally entails a further step of performing a reverse look-up of GPS coordinates representing the current location to determine address information for including in the communication. Location information, such as maps or URLs to maps can be sent directly from an e-mail application or instant messenger without having to separately launch a mapping application.
Abstract:
A system and method are provided that incorporate subjects or subject lines into instant messaging sessions or conversations on a mobile device. During an instant messaging session, the user is provided with an option to specify a subject for at least the current portion of the session or for the entire session. The subject is proposed to the other users in the session, who can accept, ignore or modify the subject at their end. Multiple subjects can be specified for a single conversation if desired, and the subjects can be displayed with the contact in a message list. The instant messaging sessions may then be searched using search tools that are typically used for search email and other data messages.
Abstract:
A wireless communications device includes a radiofrequency transceiver having a wireless voice channel for transmitting and receiving voice communications and a separate wireless data channel for concurrently transmitting and receiving other data. The wireless communications device also includes a memory operatively connected to a processor for processing current location data received over the data channel from another communications device with which the wireless communications device is simultaneously communicating on the voice channel. The wireless communications further includes a display for displaying a phone screen during a voice call, the phone screen presenting call-related information. A map is displayed on the phone screen during the voice call, the map presenting a location current of the other communications device based on the current location data received over the data channel. Optionally, the map can also show the current location of the wireless communications device.
Abstract:
A handheld electronic device, such as a GPS-enabled wireless communications device with an embedded camera, a GPS-enabled camera-phone or a GPS-enabled digital camera, determines whether ephemeris data needs to be obtained for geotagging digital photos taken with the device. By monitoring user activity with respect to the camera, such as activation of the camera, the device can begin pre-acquisition of a GPS position fix by obtaining needed ephemeris data before the photograph is actually taken. This GPS pre-acquisition improves the likelihood that a position fix (GPS lock) is achieved by the time the photo is taken (to enable immediate geotagging). Alternatively, the photo can be geotagged retroactively by appending the current location to the metadata tag associated with the digital photo. An optional acquisition status indicator can be displayed on a user interface of the device to indicate that a position fix is being obtained.
