The present invention provides for a method and system for measuring data quality of service in a wireless network using multiple peripatetic (i.e. mobile) and/or stationary, unattended, position, and performance instruments (PUPPIs) that are remotely controlled by a back end processor. In some embodiments of the invention, the data service whose quality is measured relates to wireless Internet access, e-commerce transactions, wireless messaging, or push technologies. In other embodiments of the invention, the system includes an element that is located within the wireless network infrastructure, for example, at the WAP gateway to monitor the wireless data protocol and to perform benchmarking measurements.

Bitwise monitoring of network performance

A wireless network can be easily optimized utilizing processes according to the present invention. A simulation environment allows a network engineer to vary parameters (e.g., antenna height, tilt, and power) of a virtual model of the wireless network and observe how the changes affect coverage. Algorithms also enable hand off timing parameters for sectors in a wireless network to be optimized. One algorithm analyzes measured data regarding network coverage and regional terrain to arrive at a report containing recommended values for window size parameters (code division systems) or timing advance parameters (time division systems). Another algorithm analyzes measured data regarding network coverage to arrive at a report, containing recommended neighbor lists for each sector in the network.

A method and apparatus for the re-routing of e-mail sent to a prior address (or an address that is non-working, or temporarily inconvenient) to the new address of an intended recipient. E-mail that is to be sent to a recipient is sent to the former Internet Service Provider (ISP). Because the recipient is no longer a subscriber to the old ISP, or because the address at the old ISP is temporarily inconvenient, the e-mail is re-routed to a re-route server of the present invention. The re-route server then causes the e-mail to be sent to the correct address through a variety of processes. Alternatively, new e-mail addresses are made available at the old ISP. The old ISP can then forward e-mail messages directly to the new ISP.

The present invention provides for a system and method for sharing user event information (such as, and without limitation, presence on a network) among mobile (wireless) devices and those connected to fixed IP networks such as the Internet. In accordance with embodiments of the invention, the system and method support instant messaging between wireless devices and fixed IP network devices and between wireless devices and other wireless devices. The term wireless device is used broadly to include cell phones, laptop computers with wireless modems, wireless PDAs, and any other remote wireless devices.
