Abstract:
User (113) requests multimedia services from a visited network (129). The user's home network (101) dynamically establishes a secure call control link between two prior negotiated call stat control function units (305) and (315).
Abstract:
A presence server (70) receives a location from a location server (60) of a mobile device (10). If the mobile device has location based communication services provisioned for it (112), the presence server retrieves a current list of businesses authorized to send notifications to the mobile device (162). If the business is at the location of the mobile device (164) and if the mobile device allows notifications from that business (168), the presence server sends the notifications to the mobile device (170).

Abstract:
A method and a system for switching a mobile device (102) from a source Base Transceiver Station (BTS) to a target BTS in a mobile network (100) are disclosed. The method includes detecting an intention to switch the cell transmitted by the mobile device. A Base Station Controller (BSC) (112) then receives the switch detect time from the source BTS and/or the target BTS. The switch detect time is processed by the BSC to determine the switch time for the mobile device. The mobile device then switches from communication with the source BTS to communication with the target BTS, based on the switch time.
