Abstract: Methods and apparatus for managing data objects in a communications network are disclosed. An exemplary method includes storing a plurality of data objects intended for rendering at a first communication device (e.g., a subscriber's communication device) in response to a triggering communication event, and transferring the plurality of data objects to the first communication device. Apparatus for implementing the preceding techniques are also disclosed.

Abstract: A technique for connecting a unique identifier to a data object is described. The connecting of a unique identifier such as a telephone number or an internet address such as an IPv6 address, to a specific data object, hereafter referred to as phonepage, will allow an A-party direct access to information that a B-party or B-party user equipment wishes to display to a connecting party. The phonepage resides in a memory in a telecommunications or data network. The phonepage may have a similar appearance to an Internet web page, but may also take other appearances. The displaying or processing of the phonepage may be made dependent upon the capabilities of the A-party user equipment.

Abstract: A method and system in which data objects including area-specific information are provided to a mobile communication device are disclosed. The device indicates a present physical location to a data object server, and the data object server returns a data object, such as an internet web page, WAP page, or other information, which contains information specific to the area in which the device is presently located. The areas for which data objects are provided can be independent of the structure of the communication network serving the mobile communication device.

Abstract: A data server derives information regarding the identities of users placing calls in a circuit-switched communication network. It performs this task by initially establishing at least one known and trusted identity “seed.” The data server uses the trusted identity seed, in conjunction with information regarding calls placed in the circuit-switched communication network, to derive additional user identities. Further, a user device may encrypt its secret identification number before transmitting it to the data server to maintain the secrecy of this information. The data server is additionally configured to modify previously derived identities when the server determines that they have become inaccurate.

Abstract: The invention concerns a method for operating a cellular radio system having a base station comprising at least one antenna with a wide area beam and at least one antenna with a narrow area beam whereby only a limited number of channels (p) are available on the at least one narrow beam antenna. According to the invention, a number of narrow beam channels are assigned to a number of mobile terminals (t, n, N) according to estimated duty cycle values (&agr;, &bgr;) on the up- and downlink channel for the respective mobile terminals in order to minimise interferences in the cellular system.

Abstract: The present invention provides a method and system for reducing the delay of the transmission of packet data including receiving data from a network via a base station and assigning a mobile station to a packet channel having an active mode and a variable fast page mode. Packet data is exchanged in the active mode until a first inactivity timer expires. The base station and mobile station are then switched to a variable fast page mode in which additional packet data can be exchanged, wherein the variable fast page mode has a greater delay between transmission opportunities than the active mode. The variable fast page mode schedules specific time slots which are monitored for the transmission and receipt of successive packets. In addition, the periodicity of future time slots can vary based on the delay between the successive packets.

Abstract: The present invention provides a method and system for reducing the delay of the transmission of packet data including storing, by a base station, data associated with a mobile station from a first packet data transaction. A packet for starting a second packet data transaction is received from a mobile station and the base station determines whether or not the packet has been correctly received. The base station correlates at least one field in the packet with the stored data. If the base station is able to identify the mobile station based on the correlation with the stored data, then the base station reserves a resource for transmission of a subsequent packet from the mobile station regardless of whether or not the packet has been correctly received.
