Abstract: Location-based grouping according to the present invention enables grouping of wireless network subscribers (S1-S4) based on their location within a coverage area (24, 26) and offering services based on their respective group affiliations.. Specifically, the location-based grouping defines a plurality of zones (Z1-Z3), identified by coordinates, within a network coverage area (24, 26) and assigns a dynamic network subscriber group number to each zone. The location-based grouping of the present invention requires that a service provider (14) maintain both a static network subscriber group database containing network-wide subscriber subscription parameters and a dynamic network subscriber group database containing zone-specific network subscriber subscription parameters, and that a network subscriber (S1-S4) register when the network subscriber enters into one of the plurality of zones (Z1-Z3) within the network coverage area (24, 26).

Abstract: A router (200) monitors (302) a data packet sent from an originator (102) via the router and addressed to a destination device (112, 116) other than the router, and determines (304) whether the data packet is potentially harmful to the destination device. The router interrupts (306) transmission of the data packet in response to determining that the data packet is potentially harmful to the destination device, including communicating (307) with a second router to cause the second router to interrupt transmission of a future data packet; and transmits (308) the data packet in response to determining that the data packet is not potentially harmful to the destination device.

Abstract: A method and apparatus provides for motion activated control of an electronic device. The method activates a function, such as a backlight feature, of an electronic device, by storing at least one motion sequence and a function corresponding to each motion sequence. Motion of the electronic device is monitored, and when it is determined that the monitored motion corresponds to a motion sequence, the stored function that corresponds to the stored motion sequence is activated. The apparatus has a motion transducer that senses motion of the electronic device, and a device controller in communication with the motion transducer that activates the corresponding function when a motion processor determines that the stored motion sequence has been sensed by the motion transducer.

Abstract: An instant message (IM) proxy according to the present invention is capable of maintaining the availability status of a mobile subscriber even when the mobile subscriber is roaming or temporarily out of a mobile network coverage area, and even after the IM proxy unsuccessfully attempts to send an instant message to the mobile subscriber. Messages will continue to be re-sent to the mobile subscriber in the near-real time manner characteristic of a typical instant message system until IM parameters programmed into a retry counter and/or the timer located at the proxy are exceeded and the IM proxy drops the message.
