Method, systems, and apparatuses are described for wireless communications. More particularly, a wireless station may connect to a wireless network using a first radio frequency (RF) band and detect a signal strength of the first RF band is greater than a roaming threshold. The wireless station may perform a plurality of scans for support by the wireless network of a second RF band in response to the detected signal strength. Each scan may occur when the signal strength of the first RF band is greater than the roaming threshold. The wireless station may selectively connect to the wireless network using the second RF band based at least in part on the scanning and a throughput supported by the wireless network over the second RF band. The first RF band may be a 2.4 GHz band and the second RF band may be a 5 GHz band.

Band preference in wireless networks

Disclosed are methods, systems and devices for addressing effects of transmission by a transmitter in an assigned uplink communication channel on a signal received at a receiver co-located with the transmitter. In a particular embodiment, communication in an alternative communication channel may be initiated in response to a determination that uplink transmission in the assigned communication channel likely interferes with at least one radio frequency receiving function.

Method, system and/or device for managing communication channels

Aspects of the present disclosure describe various techniques for handling data stall in wireless local area networks (WLANs). These techniques include, for example, a method in which wireless communications are switched at a wireless station from a first network device associated with a first radio access technology (RAT) (e.g., WLAN technology) to a second network device associated with a second RAT (e.g., wireless wide area network (WWAN) technology). The wireless station may then monitor network devices associated with the first RAT, including the first network device. The wireless station may filter results from the monitoring based at least in part on one or more threshold value and identify, based on the filtered results, one of the network devices as suitable for the wireless communications. The wireless communications may then be switched at the wireless station from the second network device to the one network device identified as suitable for the wireless communications.

Techniques for handling data stall in WLAN

A first access point (AP) detects a communication between a client device and a second AP. The first AP determines at least one criteria for AP steering is satisfied. AP steering is then used by the first AP to cause the client device to associate with the first AP, or a particular network of the first AP. For example, the first AP may transmit a disassociation message to the client device. The disassociation message may identify the second AP associated with the client device and cause the client device to disassociate from the second AP. After the client device disassociates from the second AP, the client device may select and associate with the first AP. The first AP may manage which network the client device associates with using a blacklist at the first AP.

Access point steering

An apparatus and method for allocating a data flow based on selection criteria including receiving at least one policy including at least one indication for selecting an access from two or more of available accesses; determining a selection criterion based on the data flow; and selecting the access based on the determined selection criterion and the at least one indication. In one example, the selection criterion is one of the following: a bandwidth requirement for the data flow, an application generating the data flow, a protocol used to carry the data flow, a file size, an application name/ID, a role ID, or a throughput of the data flow. In one example, the policy is a management object (MO) received from an Access Network Discovery and Selection Function (ANDSF) module and the selected access is for a wireless local area network (WLAN), a LTE network or for a 3GPP service.

Apparatus and method for allocating data flows based on indication of selection criteria

A method, an apparatus, and a computer program product for wireless communication are provided. A multi-radio device controls wireless communications by identifying one or more connection points between radio(s) of the multi-radio device and an operating system executing on a host device, analyzing a policy relating to the multi-radio device, and exposing, to the operating system, a subset of the connection points based on the policy. A modem manages a connection to an applications processor (AP) by virtualizing physical communication interfaces at the modem, providing a single Internet protocol (IP) interface representing the virtualized physical communication interfaces to a high level operating system (HLOS) at the AP, detecting a physical communication interface connected to the modem, and determining whether to expose the detected physical communication interface to the HLOS as a standalone virtualized physical communication interface, or hide the detected physical communication interface as part of an existing virtualized physical communication interface.

Configurable host interface using multi-radio device and architecture for WLAN offload

This disclosure describes systems, methods, and apparatus for per-application network traffic monitoring by extending socket functionality to include socket wrappers able to identify network traffic volume, applications responsible for the traffic, the network being loaded, and distinguish between internal device traffic and external network traffic. Network traffic shaping can then be carried out by managing an offending application's traffic. A disclosed method includes loading a call intercept library prior to loading any core libraries of an operating system, calling a socket wrapper, calling a socket by way of functions of at least one of the core libraries, and receiving at least one data packet, from a responding application external to the communications device, at the socket. The method may also include trapping a call, to read the at least one data packet; and releasing the call to the socket so the data packet is read by the destination application.

System and method for network traffic aggregation and analysis of mobile devices using socket wrappers

An apparatus or method of context-aware communication comprises obtaining, by an access terminal, a plurality of terminal data from a plurality of access terminal subsystems, one or more terminal applications, or a combination of both. Further, the various embodiments may include determining at least one context corresponding to at least a portion of the plurality of terminal data. Also, various embodiments may include creating a context profile having a context identifier identifying each context, wherein each context profile comprises profile parameters corresponding to the respective portion of the plurality of terminal data determined to correspond to the respective context. Additionally, the aspects include storing each context profile. Optionally, other embodiments may further include monitoring for the occurrence of a context corresponding to a content profile, and performing a context action triggered by detecting the occurrence of a context.
