International Classification:

G06F 9/46

US Classification:

718100

Abstract:

Services for a personal electronic device are provided through which a form of background processing or multitasking is supported. The disclosed services permit user applications to take advantage of background processing without significant negative consequences to a user's experience of the foreground process or the personal electronic device's power resources. To effect the disclosed multitasking, one or more of a number of operational restrictions may be enforced. A consequence of such restrictions may be that a process will not be able to do in the background state, what it may be able to do if it were in the foreground state. By way of example, network-based applications may be suspended until a message is received for them. At that time, the suspended application may be moved into the background state where it is permitted to respond to the message. In a similar fashion, audio application may be permitted to execute in background until suspended by user action. At that time, the application is suspended.

International Classification:

H04L 41/12
H04L 41/085
H04L 41/0893
H04L 41/14

Abstract:

Techniques are disclosed for generating device cluster capability information for a cluster of devices in a network environment. Capability information can specify capabilities of the devices in the cluster. A first user device can generate device capabilities for the first user device and obtain device capabilities for other devices in the cluster. The first user device can generate cluster capability information providing an intersection of the first set of device capabilities and device capabilities of the other user devices in the cluster. The first user device can obtain cluster capability information for other clusters in the network environment and receive a request from a service user device to perform a specific task. The first user device can transmit cluster capability information relating to a selected cluster that corresponds with the request.

International Classification:

H04L 41/12
H04L 41/0681

Abstract:

Techniques are disclosed for coordinating state information between devices in a network of devices. In one example, a first user device can obtain event information identifying an event (e.g., triggering of an alarm) associated with another user device and state information identifying a state of the other device. The first user device can report the state and event information to devices in the network. Observers corresponding to each user device can identify the occurrence of the event corresponding to the event information for each user device. An action (e.g., output an audio chime) can be performed by each device with an observer that identifies the occurrence of the event corresponding to the event information for each user device.

International Classification:

H04L 29/08
H04L 12/26

Abstract:

Apparatuses, systems, and methods for a wireless device to perform methods for mitigating HTTP transaction errors for a data connection. The wireless device may establish a data connection over a first network interface of the wireless device at an HTTP layer of the wireless device. A transport connection may support the data connections and may support multiple HTTP transactions. An advisory signal may be received at the HTTP layer and, responsive to the advisory signal including first information, the HTTP layer may determine that at least a portion of the HTTP transactions can be (safely) retried. The HTTP layer may terminate, without notifying the application layer, the portion of HTTP transactions and may initiate, via a second transport connection established over a second network interface, retries of the first portion of HTTP transactions.

H04W 76/10
H04W 36/26

Abstract:

Apparatuses, systems, and methods for a wireless device to perform data stall mitigation. The wireless device may establish, at an HTTP layer of the wireless device, a data connection over a first network interface of the wireless device. The wireless device may compare an available duration of data in a data buffer associated with the data connection to a first threshold and notify, in response to the available duration approaching the first threshold, at least one lower layer of the wireless device of an emergency deadline. At least one lower layer may perform one or more remedial actions to avoid and/or mitigate a data stall.

International Classification:

US Classification:

709224

Abstract:

In some implementations, a network daemon can manage access to a mobile device's network interface. The network daemon (e.g., network connection managing process) can monitor the condition of the mobile device's network connection on one or more interfaces. The network daemon can monitor many conditions on the mobile device. The network daemon can receive background networking requests from network clients (e.g., processes, applications) that specify criteria for initiating a network connection. The network daemon can then smartly manage network connections taking into account network conditions, mobile device conditions and/or client criteria received in the client request. This can help reduce battery life impact, memory usage, likelihood of call drops, data usage cost, and load on network operators.
