Title: System and methods for automatic negotiation in distributed computing
Inventor: BACIK ROMAN
IPC: H04L29/08
Filed: 2001-09-13
Abstract: This invention provides a methodology for negotiating parameters in a distributed computing environment. The invention may be implemented in a way which is simple, general and robust. Leasing, deadlock detection and starvation detection may be provided. The invention may be applied to automatic configuration of networked devices and their services. In one embodiment, devices on a computer network provide services. In each instance where one service imports functionality from another service a finite state machine associated with each service is instantiated.      The finite state machines exchange messages which cause them to progress through a sequence of states. The messages contain configuration data. When the finite state machines have reached their final states the functionality in question is made available to the importing service. The finite state machines enforce incremental negotiation. The finite state machines also provide smooth recovery from errors and interruptions in network availability.

Title: Preservation of cell borders at hand-off within a smart antenna cellular system
Inventor: DESGAGNE MICHEL
IPC: H04B7/04
Filed: 1999-12-28
Abstract: A cellular communications network includes a plurality of cells (100) whose base stations have both sector (104) and smart (110) antenna capabilities.  While engaged in a call (200), mobile station (114) downlink signal strength measurements (202,204) are made on its own serving traffic channel and the control channels of neighboring cells. These measurements are then adjusted (210) by one or more factors which take into account the operational and physical differences between sector antenna and smart antenna. For example, the signal strength measurements may be appropriately adjusted by measured differences in gain between the smart antenna and sector antennna, output power backoff values associated with smart antenna and sector antenna support of the traffic channels in comparison to the control channels, and power control attenuation applied to the traffic channels. The resulting adjusted downlink signal strength measurements may then be compared against each other (as off-set by any imposed hysteresis value) to more precisely locate the mobile station and uniformly, predictably and accurately identify when it is appropriate to authorize a hand-off

Patent CA-2370934-A1 (CA)
Title: Secure electronic commerce
Inventor: ITWARU MARK
IPC: G06Q20/00
Filed: 2002-02-22
Abstract: Secure transactions are achieved over a public network by using a private network to handle the sensitive information of the transaction. When a client requests a product from a vendor server over a public network, the vendor server notifies a facilitation server on the public network. This results in the client receiving a set of computer readable instructions from the facilitation server. The set of instructions provide access instructions to a transaction server system on the private network so that sensitive transaction information is sent to the transaction server system on the private network rather than over the public Internet. Where the sensitive information is credit card information, the transaction server system may obtain authorisation for the transaction from a financial institution and then notify the vendor accordingly. Where the sensitive information is the identity of a user of the client, the transaction server may selectively authorise the transaction without the vendor being apprised of the identify of a user of the client. Secure communications may also be achieved by sending sensitive communications over the private network.

Title: Allocation of a server address to a terminal
Inventor: FEYERABEND KONRAD
IPC: H04Q7/34
Filed: 2001-01-18
Abstract: The present invention relates to a method for allocating an address of a data service offering server to a communication device such as a mobile services device or a SIM card. With the allocation, the server address is selected from a number of address identifiers. Each address identifier identifies a valid server independently of the current server configuration of the communication network.  The server address can be combined out of a fixed and a variable portion. Moreover, the address identifiers can be updated, for example, by means of a so-called DNS server. The described server address allocation method improves the scalability of the communication system and offers an efficient measure for load distribution for both the data service offering application servers and for so-called DNS servers.  Moreover, the invention relates to a corresponding communication device for allocating a server address, and to a corresponding communication system and computer program.
