Techniques are described for position source selection. In an implementation, an electronic device provides a variety of functionality including at least functionality to determine position. The electronic device may be further configured to select between a plurality of position sources to determine position based upon a variety of selection criteria. In an implementation, a last known position may be stored when position is being determined through the plurality of position sources. The last known position may be used as an alternative to determining position via the position sources when one or more of the position sources are unavailable. In another implementation, the last known position may be employed to automatically select one of the plurality of position sources to be used by the electronic device for determining position.

Techniques are described that facilitate the automatic creation of journals that may include a variety of related content. Journal creation functionality may be furnished by a server to one or more client devices to create journals of content that include content from one or more content sources. The content provided by the content sources includes tags (e.g., metadata) describing the content. Thus, a client device may furnish a request to a server to create a journal of content. The request includes an attribute to relate the content of the journal. The server causes content to be associated with the journal from one or more computer-readable content sources accessible by the server by associating one or more of the content tags with the attribute for one or more existing journals and thereafter creating the journal using the processor by causing content from the one or more existing journals to be associated with the journal, the associated content having tags associated with the attribute.

The present invention discloses a method and device for transmission self-configuration in a Self-Organized Network (SON), said method includes: a Dynamic Host Configuration Protocol (DHCP) client reporting a device identifier of this DHCP client to a DHCP server; said DHCP server configuring a transmission parameter for said DHCP client according to said device identifier, and sending said transmission parameter down to said DHCP client, said transmission parameter at least including an IP address of said DHCP client; and said DHCP client performing self-configuration according to said transmission parameter. The present invention uses the device identifier to allocate a fixed IP address, which is able to overcome the drawbacks caused by using the MAC address to allocate the fixed IP, and has a very strong maintainability.

Techniques are described to decode location information in content accessed by a mobile electronic device and pass the decoded information to a native mapping application to provide an enhanced user experience. In an implementation, location information is decoded by parsing a map link in content accessed by the mobile electronic device or from location information parameters associated with a mapping application programming interface (API) call made by a mapping script embedded in the content. The decoded location information is passed to a native mapping application of the mobile electronic device. A map-related function may then be provided by the mobile electronic device by accessing functionality of the native mapping application using the decoded location information.
