Methods and systems for controlling implementation of a location-based service for a wireless communication device
A wireless communication device (WCD) stores a location of a portable WAP and is configured to report the stored location of the portable WAP to a location-based service provider (LBSP) when the WCD is within coverage of the portable WAP and requests a location-based service from the LBSP. While the WCD is within coverage of the portable WAP, the WCD (i) uses a wireless-communication interface to detect that the WCD is also within one or more particular cellular coverage areas and (ii) stores a correlation between the portable WAP and the one or more particular cellular coverage areas. Thereafter, while the WCD is again within coverage of the portable WAP, the WCD determines that the WCD is not within coverage of the one or more particular cellular coverage areas. In response, the WCD reconfigures itself to not report the stored location of the portable WAP to the LBSP when the WCD requests the location-based service. |

Instant simultaneous messaging
The present invention relates to a process that enables nearly real-time exchange of instant simultaneous messages between the users of a digital communication network. Instant Simultaneous Messaging enables “real” simultaneous exchange of contents between the users over a subject. This simultaneous exchange ensures that each user can access other users' contents with exactly the same order, e.g. privilege. Therefore, none of the users within a simultaneous conversion can be affected by other users' messages. The purpose of instant simultaneous messaging is to heal herd mentality by enforcing novelty/originality to the contents that are exchanged between the users. Therefore, while users are communicating over a subject simultaneously, a given user can not learn or get affected by other users' opinions before disclosing its own.

Conveying instant messages via HTTP
A system and methods are provided for conveying connection-oriented communications (e.g., textual messages among multiple users) via a protocol such as HTTP (Hypertext Transfer Protocol). When a device operating a communication application that features a custom application layer protocol for formatting messages for transmission cannot connect to the system hosting the application using a default protocol stack that include the custom application layer protocol, it instead connects using HTTP's chunked mode of transfer encoding. Each outgoing communication is encapsulated in a separate HTTP chunk, and communications to multiple different users may be conveyed via the one connection. Incoming communications (e.g., from the multiple users) are received as separate chunks and are unwrapped or de-encapsulated to retrieve the communication for presentation to a user. |

End-to-end quality of service and flow control for adaptive channels
Providing quality of service (QoS) for applications such as Voice over IP (VoIP) and enforcing service level agreements (SLA) are major requirement in any current and future communication networks. On the other hand, more communication networks are employing adaptive transmission mechanisms, such as DVB-S2 ACM in satellite communication networks. In non-adaptive networks, QoS enforcers use static bit rate configurations. However, using a static bit rate configuration in an adaptive network may result in underflow situations, during which it may not be possible to utilize the full capacity of the transmission channel and expensive resources may therefore be wasted, In addition, using a static bit rate configuration in an adaptive network may result in overflow situations, during which it may be necessary to drop user traffic packets and therefore quality of service may not be maintained. It is therefore imperative that QoS enforcers have knowledge of the network's available bit rate at all times. This invention describes a method for achieving exactly that. |
