摘要:
While a mobile node is engaged in a communication session via a first air interface channel, the user of the mobile node requests a vertical handoff. In response to the user's handoff request, the mobile node goes into a dormant mode to release the first air interface channel. The mobile node then acquires a second air interface channel, which may have a higher data rate than the first air interface channel, and continues the communication session via the second air interface channel. The mobile node may also determine that a vertical handoff may be available, e.g., by checking a preferred roaming list (PRL), and then indicate to the user that a vertical handoff may be available.

A method for management of call tones (tones that a caller hears when they call a party) is described which is particularly suitable for use by wireless telephones. The management of call tones can by performed off line. The method includes a step of: a) downloading a call tone and associated identification data to the wireless telephone (e.g., downloaded from a call tone website); b) establishing, on the wireless telephone a correlation between the call tone identification data and a contact entry stored in memory on the wireless telephone; and c) transmitting a message from the phone to a network server that includes the correlation established in step b). Subsequently, when a telephone associated with the contact entry calls the wireless telephone the call tone is provided to the calling telephone.

An adaptive media distribution system provides an on demand user experience across a limited throughput wireless network by selectively utilizing available storage on a handheld communication device, taking advantage of increased availability of extended memory solutions. Creation of an adaptable user interface (UI) widget (e.g., Trig) serves as a near real-time mechanism for delivery of media content, overcoming the over-the-air latency and difficulties with streaming interoperability. Yet, for handheld communication devices with limited storage, the adaptive media distribution system further allows legacy devices to receive on demand services via streaming, albeit with the requisite relatively long latency associated with cellular multimedia services.

A method is disclosed for dynamically varying a content download depending on whether the download is a foreground-download or a background-download. When a server receives a content-request from a device, the server determines whether the content-request is foreground-generated or background-generated and accordingly selects a set of content to transmit in response to the device. If the content-request is background-generated, for instance, the server may select a smaller quantity of content, since the device user might not be actively involved with the download. On the other hand, if the content-request is foreground-generated, the server may select a larger quantity of content, since the user is involved at the time. Alternatively, the device itself may select a location from which to request content, based on whether the download is a foreground-download or a background-download.
摘要:
A method and apparatus for managing data resources on a computing device. One or more data resources are pre-loaded on the device but are not accessible to application programs on the device. A resource manager sits on the device as an intermediary or gatekeeper to manage the data resources. The resource manager maintains a set of access-rights data that indicates for each of the data resources whether a right exists to access the data resource. In response to a request to access or add a given one of the pre-loaded but not yet accessible data resources, the resource manager invokes a network-based rights-acquisition session through which the device acquires a right to access the data resource. The access-rights data is then updated to reflect that an access-right exists, and access is thereafter allowed.

Apparatus and methods for transport optimization for widget content delivery includes obtaining updated content corresponding to a mobile widget having a plurality of informational hierarchical depths, and obtaining user navigation pattern historical data corresponding to the mobile widget, wherein the user navigation pattern historical data corresponds to the plurality of informational hierarchical depths. The aspects also include obtaining a first informational hierarchical depth range for inclusion in a first content update message for delivery to a device, wherein the first informational hierarchical depth range is based on the user navigation pattern historical data. Further, the aspects include generating a content update message with a first portion of the updated content corresponding to the first informational hierarchical depth range. Optionally, the aspects further include reducing a size of the first portion of the updated content in the first content update message, thereby defining a first compressed portion of the updated content.

Methods and apparatus for scheduling a content update of a mobile widget are provided. The method may include receiving a widget update consideration. The method may also include generating a content update schedule for a mobile widget based on the update consideration. Further, the method may include storing the generated content update schedule for use in updating a content of the mobile widget.
摘要:
A contact list client application running on a client device operates to request and receive contact lists over a network from a plurality of different contact list servers, and the application stores the contacts from these lists in a merged contact list. When a user selects a contact in the merged list, the contact list client application identifies one out of a plurality of communication applications on the client device and causes the identified communication application to initiate communications with the contact. Contact lists that relate to different communications formats, such as voice communications, SMS (short message service) messages, and email can be integrated into a single client view on the client device.

A method and system provides for restricting access to particular network content. In one embodiment, a gateway can receive, from a client device, a content request that includes a rating-allowance for the requested content. The gateway can also receive, from a content provider, a content-rating for the requested content. The gateway can then compare the content-rating to the rating-allowance and, in response, either allow or block the delivery of that content to the client device.
