Video share

Video Share is an IP Multimedia System (IMS) enabled service for mobile networks that allows users engaged in a circuit switch voice call to add a unidirectional video streaming session over the packet network during the voice call. Any of the parties on the voice call can initiate a video streaming session. There can be multiple video streaming sessions during a voice call, and each of these streaming sessions can be initiated by any of the parties on the voice call. The video source can either be the camera on the phone or a pre-recorded video clip.
Video share is initiated from within a voice call. After a voice call is established, either party (calling or called) can start a Video Share (VS) session. The sending User is then able to stream one-way live or recorded video. The default behavior is that the receiving handset will automatically go to speakerphone mode when video is received, unless the headset is in place. The sender will be able to see what is being streamed on their handset, along with the receiving User. In this scenario, the sender can “narrate” over the CS audio connection while both parties view the video. Both users will have the ability initiate a video share session, and either the sender or recipient in a video share session can terminate the session at any time. As part of the VS invitation, the recipient can choose to reject the streamed video. It is intended that both sender and receiver will receive feedback when the other party terminates a session or the link drops due to lack of coverage.
The Video Share service is defined by the GSM Association (GSMA). It is often referred to as a Combinational Service, meaning that the service combines a circuit switch voice call with a packet switch multimedia session. This concept is described in the 3rd Generation Partnership Project (3GPP) specification documents 3GPP TS 22.279, 3GPP TS 23.279 and 3GPP TS 24.279. The Video Share service requires a 3GPP compliant IMS core system.
GSM Association has split the Video Share service definition [1] into 2 distinct phases. The first phase (also called Phase 1) involves sharing a simple peer-to-peer, one-way video stream in conjunction with, but not synchronized to a circuit switch voice call. The second phase (also called Phase 2) introduces the Video Share Application Server in the solution and supports more complex features and capabilities, such as point-to-multipoint video share calls, video streaming to a web portal, and integration of video share with instant messaging.
In the industry, Video Share is also referred to by other names such as See What I See and Rich Voice Call.

A mobile Virtual Private Network (VPN) is telecommunication solution that integrates all offices and employees in a common network that includes all mobile and desk phones. Simultaneously mVPN makes internal communication more efficient, by providing additional services and guarantees high quality for best value. Through a connection between a leased line (E1/T1) and an enterprise PABX (Private Automatic Branch Exchange) system, it connects remote and mobile users with the company.[1]
Using mVPNs the company has the following advantages [2]:
Direct connectivity - the corporate network becomes part of mobile operator's network through direct connection
Private numbering plan - the communication is tailored to company organisation
Corporate Business Group - all offices and employees are part of one common group, that includes all mobile and desk phones
Short dialling - a short number to access each employee, no meter on his mobile or desk phone
Smart Divert - easy divert within company group
Groups and subgroups - Several sub-groups could be defined within the group with different changing as well as with separate numbering plan
Calls control - certain destinations could be allowed or barred both on mobile and desk phones.
MVPN also stands for Multicast-VPN, which is an IETF draft which describes the implementation of customer multicast traffic over a service provider enabled MPLS backbone.

BlackBerry handhelds are integrated into an organization's e-mail system through a software package called "BlackBerry Enterprise Server" (BES). Versions of BES are available for Microsoft Exchange, Lotus Domino and Novell GroupWise. While individual users may be able to use a wireless provider's e-mail services without having to install BES themselves, organizations with multiple users usually run BES on their own network. Some third-party companies provide hosted BES solutions. Every BlackBerry has an id called BlackBerry PIN, which is used to identify the device to the BES.

CPU
Early BlackBerry devices used Intel-80386-based processors.[6] The latest Blackberry 9000 series is equipped with Intel XScale 624MHz CPU,which makes it the fastest Blackberry to date. Earlier BlackBerry 8000 series smartphones, such as the 8700 and the Pearl, are based on the 312MHz ARM XScale ARMv5TE PXA900. An exception to this is the BlackBerry 8707 which is based on the 80MHz Qualcomm 3250 chipset, this was due to the ARM XScale ARMv5TE PXA900 chipset not supporting 3G networks. The 80MHz Processor in the BlackBerry 8707 actually meant the device was often slower to download and render web pages over 3G than the 8700 was over EDGE networks.

BlackBerry 7250RIM provides a proprietary multi-tasking operating system (OS) for the BlackBerry, which makes heavy use of the device's specialized input devices, particularly the scroll wheel (1995–2006) or more recently the trackball (September 12th 2006–Present). The OS provides support for MIDP 1.0 and WAP 1.2. Previous versions allowed wireless synchronization with Microsoft Exchange Server's e-mail and calendar, as well as with Lotus Domino's e-mail. The current OS 4 provides a subset of MIDP 2.0, and allows complete wireless activation and synchronization with Exchange's e-mail, calendar, tasks, notes and contacts, and adds support for Novell GroupWise and Lotus Notes.
Third-party developers can write software using these APIs, proprietary BlackBerry APIs as well, but any application that makes use of certain restricted functionality must be digitally signed so that it can be associated to a developer account at RIM. This signing procedure guarantees the authorship of an application, but does not guarantee the quality or security of the code.

Similar hoaxes
Similar hoaxes
A similar hoax was attempted in July 2005. This hoax proposed a sexual practice called "greenlighting," in which men and women wore green shirts with the collars turned up, and had sexual relations with whoever turned the collars down. In truth, no such sexual practice has taken place on any notable scale. The hoax similarly involved posts to the blogosphere, and various sites that purported to coordinate and discuss among "greenlighters".
Toothing
Toothing
It appears that toothing started around March 2004, in the form of a fake forum designed by Ste Curran, then Editor at Large at games magazine Edge, and ex-journalist Simon Byron. On April 4, 2005, the creators of the forum admitted that the whole thing was a hoax.[1]
In toothing, a Bluetooth device is used to "discover" other enabled devices within about 30 feet (10 meters), then send the expression toothing? as an initial greeting. In addition, or when sending of text messages via Bluetooth is not possible, the Bluetooth name of the phone can be set to toothing? or something else to indicate interest. Since the hoax, there have been real Bluetooth dating devices to hit the market.
