20110134897 | SYSTEM AND METHOD FOR MULTIMEDIA EMERGENCY ACCESS IN A WIRELESS NETWORK - A method for distributing multimedia emergency contact information using an access point of a wireless local area network (WLAN) is disclosed. The access point is configured to retrieve service contact information from a lookup table. The method includes receiving a first generic advertisement service (GAS) query from a WLAN device. The first GAS query includes a uniform resource name (URN) identifying at least one of the services. The method includes retrieving contact information for the at least one of the services identified in the first GAS query. The contact information includes a uniform resource identifier (URI). The URI is configured to include session initiation protocol (SIP) URIs, and telephone URIs. The method includes transmitting a GAS query response to the WLAN device. The GAS query response includes the contact information for the at least one of the services identified in the first GAS query. | 06-09-2011 |
20130070644 | DISCOVERING NETWORK INFORMATION AVAILABLE VIA WIRELESS NETWORKS - Network information may be discoverable without requiring a connection to that network. For example, Access Network Query Protocol (“ANQP”) may allow a device to discover information about a network prior to the device associating with that network. In other words, ANQP allows a network terminal to request additional network information prior to establishing network capability. The additional network information that may be discoverable includes network latency, cellular capabilities, hotspot capabilities, mobility capabilities, neighbor reports, station identification, and multiple hotspot session identification. | 03-21-2013 |

20130121325 | Caching Network Discovery Responses in Wireless Networks - Network information may be discoverable without requiring a connection to that network. For example, Access Network Query Protocol (“ANQP”) may allow a device to discover information about a network prior to the device associating with that network. The network discovery information may be stored in a cache memory for future associations with the same network. | 05-16-2013 |
20130229923 | Methods And Apparatus For Improved Scanning Of A Radio Frequency (RF) Band For WLANs In An Unknown Regulatory Domain - Techniques are described for use in scanning by a mobile device which is configured to communicate in compliance with regulatory requirements of a regulatory domain based on country information communicated in one or more beacon frames. The mobile device scans a radio frequency (RF) band using passive scan operations on RF channels having passive scan status, where each passive scan operation involves monitoring an RF channel in attempt to decode a beacon frame. When the mobile device successfully decodes, on an RF channel for a passive scan operation, an information frame of a type that is different from a beacon frame, it changes the passive scan status of the RF channel to an active scan status and performs an active scan operation on the RF channel. | 09-05-2013 |
20140119353 | MULTIPLE ACCESS POINT NAME AND IP SERVICE CONNECTIVITY - A mobile device may communicate through multiple access point names (APNs) through wireless local area network (WLAN) protocols. The APNs are data routes that may be accessible to a device through other non-WLAN networks (e.g. cellular), but can be accessed with a WLAN device through WLAN protocols. A sub network access protocol (SNAP) header may be modified and used for routing traffic. | 05-01-2014 |
20140171082 | METHODS AND APPARATUS FOR USE IN IMPROVING NETWORK COVERAGE FOR VOICE OR DATA CALLS - To improve network coverage or reduce false handover triggering, at least one client terminal is set to operate as a virtual access point (VAP) in a first wireless network by an AP controller. If a mobile device detects that a signal quality estimate of communications via an AP or the first wireless network is below a first value, the mobile device performs a handover procedure to the VAP. While maintaining the call via the VAP, if the mobile device detects that the signal quality estimate is beck above the first value, the mobile device performs a handover procedure back to the AP of the first wireless network. On the other hand, if the mobile device detects that the signal quality estimate is below a second value which is less than the first value, the mobile device performs a vertical handover procedure from the VAP to a base station of a second wireless network. | 06-19-2014 |
