Abstract: Packet data transmissions from network servers are provided to wireless communication stations via wireless communication networks. A network server 30 about to transmit packet data to a wireless communication station 20 first requests the wireless station 20 to provide its radio transferring capabilities to the server 30. Based on these radio transferring capabilities, the information content to be transferred from the server 30 to the wireless station 20, via a wireless communication network 10 and any operatively connecting the server with the wireless network 10, is adapted so that the resulting packet data transmission is suitable for the radio transferring capabilities of the wireless station 20. This results in a reasonable transmission time in elimination of any annoying transmission delays due to bandwidth capacity problems.

Abstract: A system and related method for supporting non-intrusive and effective voice communication among mobile users in which voice calls between mobile users are managed based on callee availability, caller-callee relationships, and non-intrusive information exchange, including interactive exchange at the time of call setup but prior to the call being answered. Callee availability can be based on callee device status, calendar activities, location, past behavior and other factors. The caller-callee relationships specify whether the callee is available, unavailable or on restricted availability relative to the caller. The interactive exchange can be implemented using voice and/or text/graphic displays on caller and callee mobile device. Callees are provided with options for handling the call. Callers are provided with information regarding the callee's current and future availability and willingness to receive a voice call from the caller, thus maximizing the chance of caller reaching the callee on every voice call.
